Kang Jingwei: Intelligent hardware will become the next entrance in the Internet of Things era

Kang Jingwei believes that the most important thing in the Internet of Things era is not capital, nor how big the company is, but innovation and creativity. In the future, people with innovation and creativity will be the masters of this world.

In his view, the manufacturing of the Internet of Things and intelligent hardware will be the entrance to the next generation of manufacturing. Kang Jingwei said that no matter what you do today, if you do not grasp the technological transformation of smart hardware and the Internet of Things after 5 or 10 years, many Chinese manufacturing companies may not survive. Nowadays, many traditional industries, if you look at the next 5 to 10 years, many of the items around you will be smart hardware, clothes, shoes, lights at home, chairs, and even drinking cups. Smart hardware.

Finally, Kang Jingwei shared his philosophy: to be a company today, to be an entrepreneur, we must invest in tomorrow's innovation, so that we can make a company able to do 5 or 10 years later, will not spend a time on the market. It shines like a meteor.

Live speech record:

Good afternoon everyone! Today, I am very simple to share with you the history of simple entrepreneurship as a startup company in the past 25 years.

In the past 25 years, I have founded four companies, two companies in the past 15 years, one design, and one Internet company. My first company was founded in 1995, listed in NASDA in 2005, which is relatively successful. The second company invested in the Internet bubble in 2000, and invested in the establishment of the first Internet company. After two or three years of struggle, it was forced in 2004. The success rate of entrepreneurial history in the past 15 years is only 50%, one listing, one failure. The lesson of the past 15 years, I started to do two other companies five years ago. In 2011, I started Cogobuy. After more than three years, I listed on the Main Board of Hong Kong in 2014, as China's largest, serving China's electronics manufacturing industry. The company's procurement of e-commerce platforms has maintained a rapid growth of 50% to 100% per year for the past five years. From this point of view, this enterprise is considered to be a successful business, and the third enterprise is considered a successful business. At present, Coton Core City's annual trading volume in Hong Kong stocks exceeds 20 billion yuan this year. The company's market value is about 18 billion Hong Kong dollars, which is used in all indexes of Shenzhen-Hong Kong Stock Connect and Shanghai-Hong Kong Stock Connect.

As a company, we use the Internet + model to serve the electronics manufacturing industry in Hong Kong. We have innovated a new service model and have made great progress. As a company, especially on the Internet, everyone knows that there is no secret in the business model itself, and there is no end to innovation. When I decided to go public in 2014, I was an internal assessment. If I couldn't prepare for two years, we would come up with a new service and new innovation. Maybe after two years, no matter how good we are, it is only a matter of time to be eliminated. From the end of 2013 to the beginning of 2014, we saw a new opportunity. In January 2014, Google announced that it would spend $3.2 billion to acquire ENST. We found this to be a new era of the Internet of Things. Google can actually spend $3.2 billion to acquire a hardware company that acts as a home alarm. What does this mean? This shows the coming of a new era. Starting from the Google project, the Internet market will completely evaluate all enterprises that make Internet and IoT smart hardware. This is no longer the traditional manufacturing industry, but the next generation of mobile Internet.

From here on, at that time, we understood the Internet of Things and the intelligent hardware very simple. The Internet of Things and intelligent hardware are actually artificial intelligence Internet of Things = artificial intelligence (AI) + hardware + cloud, three-in-one integration, so that these are lifeless. The things of thought have life and thoughts to serve human beings. This is the Internet of Things in our human heart. The most important thing in the Internet of Things era is not capital, nor how big your company is, but innovation and creativity. In the future, people with innovation and creativity will be the masters of this world. This is a small company, a big company, a new company. It doesn't matter to the guests. At that time, we thought about whether we could build an Internet platform and serve the innovative entrepreneurs of smart hardware in China. We launched a platform called Hard Egg.

Many investors ask me the first question is, why is this company's name hard? In fact, our name is to ask our young people to spend a hundred dollars on crowdfunding. At that time, the goal was very simple. We passed the hard egg and the goal was to incubate the smart hardware enterprise through the Internet. This was our original intention. What do we do to incubate this company? We are an Internet platform, connecting people who do smart hardware and innovative ideas on the one hand, that is, people who make ideas such as drones and robots today. We connect these people with the resources of China's manufacturing industry, and connect them with companies in the Pearl River Delta and the Yangtze River Delta around the mold, processing, and design, and help innovative entrepreneurs through the resources of China's manufacturing industry. One thing, turning their ideas into products, this is the original intention of the hard egg at that time, we want to create a supply chain that specializes in intelligent hardware innovation and entrepreneurship.

After more than two years of development, especially with the help of the country's strategic support since 2015, the hard egg platform has become China's largest intelligent hardware innovation and entrepreneurial platform today. In the figures released by Q3, we are in Q3. At the end of the day, there are more than 16,000 smart hardware projects on the hard egg, about 80% of which are from China's innovative and entrepreneurial companies, and another 20% from Silicon Valley, Israel, Europe, Japan and overseas innovation and entrepreneurship projects. We use the Internet to connect more than 14,000 suppliers around Shenzhen, including some companies in the Pearl River Delta and the Yangtze River Delta. We create more than 16 million smart hardware fan bases. Create a closed loop in intelligent hardware B2B2C, serving the world as an innovative entrepreneur of intelligent hardware.

At the beginning of our platform, we learned Taobao and built such a platform with the free model. At that time, our original intention was to serve the makers and entrepreneurs, so we were initially positioned as a platform. But as the scale of the platform expands, we have found a very interesting phenomenon this year. Today, our hard egg platform is not just a small company, a startup company, we found that a large number of traditional enterprises joined the hard egg platform this year, for example, a microwave oven company in Shunde, he transformed into a smart microwave oven; a refrigerator company, he Transforming into smart refrigerators and smart homes; one of the audio companies to transform into smart audio, these needs are particularly high. Suddenly, one day we found that our hard egg platform has gradually evolved from helping young people to create a platform for transformation and upgrading of traditional Chinese manufacturing.

How can we help these companies transform and upgrade? We first put two core resources on our platform. The world's top 500 technologies, you can't do without the core technology companies such as chips, artificial intelligence, motors, etc. First of all, we bring the world's most core technology companies like Intel, Qualcomm, Microsoft, Google and other core technology companies on our platform. They have the core technology to do the lowest level of intelligent hardware. At the same time, we will increase the production capacity of China's manufacturing industry. We put the supply-side structural reform resources on the platform for the past two years, freely open to the Chinese and global entrepreneurs, and also to a large number of traditional Chinese enterprises. In this way, we can help many large-scale traditional Chinese manufacturing companies to transform and upgrade through intelligent hardware, regardless of the makers and entrepreneurs. This is the next step in the world's largest manufacturing sharing. Economic platform.

In the past, we feel that the form and method of doing the company in the future is totally different from the past capitalism. For the sake of the size of the company, we need a sparrow, but we are thinking about the future company form. If we share a lot of services through shared economic methods and then help to innovate entrepreneurs, there is a typical case for me, which is very instructive. I saw a privately-designed space shuttle company in Silicon Valley. This company has only 120 people. They used 120 people to do the work of hundreds of thousands of people in the space department. In the United States, there is already a complete ecosystem and industrial chain for the space shuttle.

If we can share the core industry chain of each industry through the Internet and share the economic model today, it is not a matter of heaven and night to design a plane and design a car at home. This is what we hardly want to build. Platform, hope that the Internet will create a shared economic platform for global manufacturing. The first output of this platform is China's high-end manufacturing capacity. I hope to link global innovation with Chinese manufacturing through the Internet.

Today we first provide the hard egg platform. We are the platform service super connector. This is to use the sharing economy model in manufacturing. Today we have a long-term judgment. Today we are talking about smart hardware. We are all talking about it. Some newer industries. For example, today our hard-core main service industry is made up of smart cars, robots, smart medical, smart homes, new materials... many new industries. But let's think about it. Today, in many traditional industries, if we look at it for 5 or 10 years, many items around us may be smart hardware. The clothes you wear, the shoes you wear, the lights of your house, the chairs you sit on, drink These are the smart hardware. So smart hardware is likely to be the entry point for the next generation of manufacturing. No matter what you do today, if after 5 or 10 years, you have not grasped the intelligent hardware, the wave of technology transformation of the Internet of Things, many Chinese manufacturing companies may not be able to survive. In our view, the manufacturing of the Internet of Things and intelligent hardware will be the entry point for the next generation of the entire manufacturing industry. We want to build such a platform to connect all the manufacturing industries of the next generation. This is how hard eggs are prepared.

China has left a very important asset in the past 20 years. Today, China is already the center of the world's largest manufacturing industry. We are the world's factories. Especially in the field of electronic products, we are basically all-encompassing, and we want all the people in the world to think about it. Electronic products are basically made in China. If we can present the capacity of these millions of Chinese manufacturing industries through the Internet, promote them to every corner of the world, connect the world's innovative and entrepreneurial people, the world's innovative and entrepreneurial companies, which will be completely through the Internet. Through the online “Belt and Road” initiative, we will push the production capacity of China's manufacturing industry to many parts of the world. This is the platform that our hard-boiled people want to build in the future, from manufacturing in China to global intelligent manufacturing. Through such a platform, we will innovate the world. Connected with Chinese manufacturing.

This is to share with you, the hard egg from a dual-creation platform, slowly become the world's largest manufacturing sharing economy platform, and finally share with us our philosophy: to do any business today, be an entrepreneur, regardless of us How about today, we want to innovate tomorrow, we want to invest in tomorrow's innovation, so that we can make a company able to do it in 5 or 10 years, it will not be a flash of light like a meteor in the market. We must continue to innovate and let us stay in this industry.

thank you all!

Wireless Bridge

1. What wireless network
Wireless network, as the name suggests, is a way to build a network without relying on network cables, which is mainly achieved by using wireless communication technology. There are two main ways of wireless network (such as 4G, 3G or GPRS) and wireless local area network (WiFi) through mobile communication networks.

2, What wireless bridge
Wireless bridge, as the name suggests, is the bridge of wireless network, which uses wireless transmission to achieve a communication bridge between two or more networks. In addition to having the basic characteristics of a wired bridge, a wireless bridge works in the 2.4G or 5.8G wireless license-free frequency band, making it easier to deploy than other wired network equipment.

From the function to understand the wireless bridge, it can be used to connect two or more independent network segments, these independent network segments are usually located in different buildings, hundreds of meters to tens of kilometers apart, can be widely used in the interconnection between different buildings.

At the same time, according to different protocols, wireless Bridges can be divided into 802.11b, 802.11g and 802.11n in the 2.4GHz band and 802.11a and 802.11n wireless Bridges in the 5.8GHz band.

3, the meaning of wireless bridge 2.4G and 5.8G
2.4G Bridge:

The advantages are low frequency, large wavelength and strong diffraction ability. Simply put, the propagation performance is good, and the propagation path is slightly shielded. Then there is the relatively low cost.

The disadvantage is that there are many devices using the 2.4G band, and the electromagnetic wave signal emitted by the bridge is easily interfered with the signal emitted by other devices, resulting in a decrease in transmission quality. Moreover, it is limited by the transmission bandwidth of the 2.4GHz band itself, which generally does not exceed 300Mbps

5.8G Bridge:

The advantages are high frequency, relatively pure channel, and large transmission bandwidth. The transmission bandwidth starts at 433Mbps and can easily reach more than 1Gbps. It is suitable for scenarios that require high data transmission.

The disadvantage is that the frequency is high, the signal wavelength is short, the penetration is poor, and there can be no shelter during the propagation. The cost of 5.8G equipment is higher than 2.4G, and it is still in the popularization stage.

Wireless bridge transmission system is usually composed of two or more wireless devices, due to the two-way transmission of data, each device needs to have the ability to send and receive wireless signals.

4, the working principle of wireless bridge
The working principle of the wireless bridge is that the bridge uses the air as a medium to transmit signals, which is simply that one end of the bridge converts the signal in the network cable into a wireless electromagnetic wave signal and transmits it to the air in a directional manner. The bridge at the other end does the opposite, picking up radio electromagnetic signals in the air and converting them into wired signals.

The wireless electromagnetic wave signal can be transmitted by air as the transmission medium, which can solve many problems of difficult construction of wired deployment: such as highways, rivers, mountain streams, or road hardening, and wired deployment and construction difficulties.

Wireless bridge networking has obvious advantages, and can achieve point-to-point or point-to-multipoint network connections at distances of up to 50 kilometers, and data transmission speeds of up to 108Mbps. Effectively solve the problem of network connectivity in the interval, as long as the wireless signal coverage area, the client can easily access the network, the fusion system, without any wiring, the wireless terminal can achieve zero configuration access, so it is very easy to carry out network maintenance and expansion.

Bridges are generally used in the following scenarios: wireless data acquisition, monitoring data transmission (outdoor and elevator), outdoor wireless coverage, outdoor remote wireless bridging, private ISP wireless broadband, unmanned monitoring station data return, etc.

5. How to choose the right bridge
Wireless bridge is a wireless monitoring and transmission equipment commonly used in the field of wireless monitoring, although it is a wireless device like wireless AP and Wireless Router, but it does not need to build wifi coverage, but is used to wireless transmission of video data. Like the switch in wired monitoring, the wireless bridge is an important transmission equipment in wireless monitoring, which is widely used in the two major fields of outdoor surveillance video transmission and elevator surveillance video transmission.

There are many kinds of wireless Bridges on the market, so how to choose a bridge that suits your needs? We will answer your questions from the following aspects.

â‘  Transmission distance

Wireless monitoring projects need to transmit the distance is not the same, wireless bridge transmission distance there are many kinds, some transmission 1~3 km, some transmission 3~5 km, some transmission 5~10 km, some transmission more than 20 km, must be determined according to the monitoring of the transmission distance, as far as possible the maximum transmission distance of the bridge is greater than the monitoring transmission distance, Because rain, fog, snow and other weather in the actual application environment will cause the transmission performance of the bridge to decline, the project construction should reserve sufficient performance margin.

â‘¡ Transmission bandwidth

There are many kinds of transmission rates of wireless bridge, such as 150Mbps, 3000Mbps, 450Mbps, 600Mbps, 900Mbps, etc., which rate to choose can be determined according to wireless monitoring requirements. What users actually need to consider is the transmission performance of the bridge over a specific distance, rather than the theoretical bandwidth data. For example, the theoretical transmission bandwidth of the IP-COM AP625 bridge is 433Mbps, and the actual point-to-point transmission bandwidth can reach 200Mbps at a distance of 2 kilometers, with 25 200W cameras without pressure.

â‘¢ Operating frequency

There are two main operating frequencies of wireless Bridges, 2.4G and 5.8G, and the characteristics of the two Bridges are different. In general, 2.4G wireless bridge is the current mainstream frequency band, good compatibility, good diffraction ability, but the anti-interference is relatively poor, especially in the urban area is vulnerable to wireless signal interference transmitted by other WiFi devices. The 5.8G channel is relatively pure, the anti-interference ability is better, the transmission distance is long, but the diffraction ability is poor.

Urban, downtown, long-distance transmission, camera stream is large, 2.4G interference is more, choose 5.8G wireless bridge. Others such as the transmission distance is relatively close, relatively remote, and the same frequency interference is less, etc. 2.4G wireless bridge is used

â‘£ antenna

Antenna is an important part of wireless bridge, used to transmit and receive wireless signals, no antenna, wireless bridge can not achieve communication. There are many types of antennas, including omnidirectional antennas and directional antennas. Omnidirectional antenna is used for short-range coverage and transmission, and directional antenna should be selected for long-distance bridge. The larger the gain of antenna, the better the performance of wireless bridge.

⑤ Power supply mode

The working environment of the wireless bridge usually involves some complex outdoor environments, such as forests, ports, tunnels, reservoirs and other places, so the power supply is a more troublesome problem. Choosing a wireless bridge that supports POE cable power supply can solve this problem well. IP-COM bridge all support PoE injector power supply, power supply distance up to 60 meters.

â‘¥ Protection level

The wireless bridge works outdoors, the environment is changeable, such as rain, rain and snow, high temperature, etc., the first requirement is waterproof, dustproof, heat resistance, and condensation resistance. For a qualified wireless bridge, these "qualities" are a must.

⑦ Pairing method

At present, there are three mainstream bridge pairing methods: key pairing, dip code pairing, automatic pairing. In terms of the simplicity of engineering applications, especially for projects that install dozens or hundreds of network Bridges at a time, automatic pairing is undoubtedly the best choice. IP-COM network bridge supports the automatic pairing of two network Bridges when they are powered on in the factory state, greatly reducing the workload.

6, wireless bridge installation requirements
Wireless bridge is an important transmission equipment in wireless monitoring, which is widely used in outdoor surveillance video transmission and elevator surveillance video transmission. In addition to selecting the right wireless bridge, we also need the bridge equipment to give full play to its performance advantages after installation to assist users in the project. Therefore, for some installation requirements and precautions of wireless bridge, we should pay more attention to avoid various problems in the later stage.

â‘  Installation height

In the process of wireless transmission, obstacles such as trees, buildings and large reinforced buildings will weaken and block wireless signals. In order to improve the wireless transmission performance and prevent signal damage and weak signal, the user should try to ensure that there are no obstacles in the transmission route of the wireless bridge during installation, and meet the transmission conditions that the two ends can see each other.

Both ends can not be simply understood as point-to-point visibility, which means that there can be no obstacles or potential obstacles in the Fresnel zone (radio wave terminology) in which the antenna is propagated. The main RF energy between the antennas is transmitted in this area, so the transmitting antenna must be high enough above the obstacle to maintain a line of sight path between it and the receiving antenna in order for the communication link to work properly.

â‘¡ Angle and signal debugging

Since the quality of the wireless bridge signal is directly related to the bandwidth and stability of the link, it is necessary to further debug the wireless bridge signal after the installation is completed (the signal strength can be adjusted by adjusting the direction of the antenna on both sides, the pitch Angle, etc.). The signal strength can be checked according to the signal status indicator of the bridge device (three lights, three signals are best, two are average, and one is poor) or the software. Detailed installation procedure for outdoor wireless aps

â‘¢ Requirements for lightning rod

When the wireless bridge is installed in the field, if there are no tall buildings or lightning rod protection nearby, lightning protection measures need to be considered, usually using lightning rod, generally installed in the urban area or surrounded by lightning rod protection, can not be set separately.

It can be seen from the characteristics of the lightning rod that the lightning rod is a lightning source, and the lightning rod will discharge in the grounding path when it is hit by lightning. Therefore, the lightning rod and the protected equipment need to be insulated, otherwise the lightning rod will have a lightning effect on other equipment when discharging. Due to the tip discharge characteristics of the lightning rod, it is easier to cause lightning discharge than the general equipment, so if the lightning rod cannot be isolated from the protected equipment, it will increase the probability of lightning strikes of other equipment. Therefore, the lightning rod grounding must be separate from the device grounding and cannot share the same grounding.

Do enterprises most afraid of products can not be sold, enterprises have no visibility. Now is the Internet era, the era of wine not afraid of the alley is gone. Want to do a good job in sales, please register for free Aike business network members, you can free release product sales information, industry exhibition information, investment information, can also release corporate news, new product delivery and other advertising articles. There are more than a dozen vertical business websites under the Aike business network, such as plastic business network, chemical business network, instrument business network and so on. Register an account and you can publish business information on more than 10 platforms for permanent display. Colleagues are on the move, you must not forget oh.

â‘£ Power supply requirements

The normal input voltage of the PoE power module of the bridge ranges from 100V to 240V and the output voltage ranges from 24V to 48V. If the voltage is lower than or higher than this voltage, the normal operation of the device is affected or the PoE power module is damaged. In view of the unstable and high voltage field power supply, it is necessary to design a PoE power supply solution (such as regulated power supply and UPS power supply) that ADAPTS to the working voltage.

Because the bridge is a precision electronic equipment, it has high requirements for power supply, and is vulnerable to the impact and influence of other power supply equipment, so the power supply of the bridge should be separated from other high-power equipment such as pumping units, oil pumps, etc. When taking power at the same location, UPS, regulated power supply or isolation transformer should be installed to filter out the influence and interference on the power supply when the high-power motor is working.

When the PoE module is used to power the bridge through the network cable, the recommended distance is not more than 60 meters. When this distance is exceeded, it is recommended to move the transmission line near the bridge to meet the recommended power supply distance.

⑤ Device grounding requirements

The wireless bridge should be grounded. If the device is not grounded, the device may run abnormally or be damaged. The grounding resistance of the device should be less than 4 ohms, and the grounding cannot be shared with the lightning rod or strong current line. If PoE power is used, the ground cable also needs to be grounded. Users can ground a Class 5 (or higher) shielded network cable with a ground cable and a PoE adapter to effectively prevent static electricity and lightning strikes. The ground cable and ground point should be waterproof using waterproof tape and waterproof cement according to the waterproof requirements to prevent the ground point from being exposed to the air for a long time, which may cause oxidation or rust.

7, wireless bridge erection method
There are four common wireless bridge transmission modes, the distribution is point-to-point, point-to-multipoint, relay, reflection, here the first monitoring combined with pictures for you to briefly introduce the characteristics of these four wireless transmission modes.

â‘  point-to-point transmission

Point-to-point transmission mode is the simplest transmission mode, that is, we often say PTP, to a single device transmission, and then received by a single device, one-to-one transmission and reception is simple and direct. Point-to-point transmission mode of wireless bridge is often used in the case that the transmission distance is long, or the monitoring point is widely distributed, and point-to-multipoint transmission cannot be achieved.

â‘¡ Point-to-multipoint transmission

The point-to-multipoint transmission mode is developed based on the point-to-point transmission mode, which is often represented as a receiving end to multiple transmitting ends, and is often used for the situation where the transmission distance is relatively close, there are more monitoring points and the distribution is dense.

â‘¢ Relay transmission

The relay transmission mode is because the transmitting end and the receiving end can not avoid the barrier blocking the microwave signal, so the transfer equipment is added in the middle, so that the microwave signal is smoothly transmitted to the receiving end through the transfer equipment, this mode is due to increase the transfer equipment and increase the equipment cost investment, so it is generally not used when unnecessary.

â‘£ Reflection transmission

Reflection transmission is microwave transmission with the help of objects outside the transmission device, such as the transmitting end and the receiving end can not be seen, but there is a large building or a mountain with smooth rock walls in the middle, so that you can adjust the Angle of the equipment, through the building or mountain to reflect microwave signals for wireless communication.
