Microsoft, Google, Magic Leap and other large and small companies are all working on AR augmented reality. Apple also believes that AR is more promising than VR. Although we can see AR蹦跶 in the news from time to time, we can even see the wonderful AR show at the “eight minutes of Tokyo†at the closing ceremony of the Rio 2016 Olympic Games. However, many students still have some misunderstandings about AR. What are the misunderstandings? 1. Augmented reality and virtual reality are one thing Knocked on the blackboard! They are two things! We have already explained the difference between AR and VR many times, so I won't go into details here. We will help you to distinguish in the most straightforward way. VR virtual reality is a real-world fantasy created by data that is completely out of the real environment. After you wear a VR glasses, you are separated from the real environment you are in, and then enter a virtual reality. For example, you obviously listen to songs in a simple student dormitory, but after wearing VR glasses, You will be able to "get in" at the star concert scene in an instant. AR augmented reality won't let you get rid of the real environment. It just integrates virtual elements into the real environment, and it's hard to tell. For example, after wearing the AR device, you can see that there are several beautiful peacocks in the house, but in fact there is no peacock at home. 2, AR is a brand new technology No no no no no, AR's history of augmented reality can be traced back to 1990, developed by Boeing engineer Tom Caudell, and used to guide shop floor staff. However, due to technical limitations, AR has not achieved any development until the last two years. Thanks to the rapid development of mobile technology, mobile phones can have built-in cameras, sensors and powerful processors, creating opportunities for AR technology on mobile phones. So, we saw the AR explosion game like Pokemon Go coming out, and let AR technology get to know thousands of people overnight. Although the Pokemon Go boom has cooled, we believe that there will be more AR content coming. 3. Augmented reality is difficult to use Maybe we think that a new technology will be difficult to use and I don't know where to start. In fact, the use of AR is very simple, almost no skills, just like our usual mobile phone application. All you need to do is download an augmented reality app from the app store. Some people may say that I don't have augmented reality devices. It doesn't matter. Some mobile phones are now able to implement AR augmented reality functions, such as Lenovo Phab 2 Pro, which will be launched on November 1. And now there are some AR applications that can be used by ordinary mobile phones. For example, Hyundai Motor released a Virtual Guide based on AR augmented reality technology to guide users to use or simply repair the car. 4, you can only superimpose pictures or text on the real environment This understanding is too simple, superimposing pictures or text on the real picture, this is only part of AR, not all. AR allows you to add all your data elements to the real world. For example, if you are an interior designer, you can put a set of sofas "real" in the living room to see the effect. 5. Augmented reality is tomorrow's technology Wrong and wrong, many companies use AR technology in the field of game consumption. For example, Coca-Cola applied AR technology to B2B sales, AR technology was also used when renovating the new site, and they also used AR technology to preview the product display. Fire Resistant Network Cable is the most commonly used twisted-pair cable flame retardant grade, its test standard is UL 1581.
If you burn it, you release a lot of heat.According to the code of construction for integrated wiring, twisted pair wires shall be laid through metal pipes and behind metal Bridges in floors, ceilings and walls.In this case, the use of ordinary twisted-pair wire can be installed in any situation without concern for smoke and toxicity.

So the CM level cable fire characteristic is as follows: not spontaneous combustion; In the flame will smoke, and may appear flame; The speed of flame spread along the cable is very slow; When the external fire source is cut off, the fire on the cable will gradually go out.
CM class cables do not take into account smoke density and toxicity (no mention of smoke density and toxicity in UL 1581) as long as they meet flame retardant rating requirements.Cm-level cables are mostly horizontal twisted-pair and are used in wiring subsystems.The sheath layer of CM class cable is mostly PVC material, while the insulation layer is high-density PE material.The advantage is that it is cheap, while the disadvantage is that the ignition point is low, the normal operating temperature is below 70℃, when the temperature reaches 160℃ or higher, THE PVC material will emit toxic halogen and smoke.
