400YK shortwave radio station Yuanyao is a remote connection control device for independent frequency selection shortwave radio stations

Shortwave communication is an important communication method that can realize long-distance communication without establishing a relay station. For many years, it has been widely used in government, military, and civil air defense departments to transmit language, text, data, and static images. Especially in the military sector, it has always been one of the important communication means for long-distance military command and bottom-line communications.

The self-selected shortwave radio is a new generation of shortwave communication equipment developed to meet the needs of the new era. It is a shortwave radio designed based on advanced cognitive radio technology and centered on user experience. It does not rely on frequency planning, contact documents and the operational capabilities of the operators. The communication parties do not need to agree on frequencies or additional service channels. As long as they turn on the phone and enter the address of the other party to call, the radio station can independently select the available frequencies and establish a communication channel for users. ". If the link is not established, the "WeChat" method similar to that of a mobile phone is used to realize voice, message transmission, and situation monitoring. The self-selected shortwave radio has the characteristics of power-on, full-time, on-the-fly, and interference-on-the-fly, which effectively solves the current problems of “difficulty in selecting frequencies” and “difficulties in using frequencies” in shortwave communications. Shortwave communication under various conditions such as complex geographical environment, long distance and all-weather can greatly improve the probability of success of shortwave communication.

The 400YK shortwave radio station is a remote connection control device for independent frequency selection shortwave radio stations. It is mainly used to meet the separation of the human-computer interaction part (hand microphone, control panel, etc.) from the radio station and antenna part in the application of independent frequency selection shortwave radio station. Long-distance) use needs to solve the urgent need to solve the urgent need to solve the urgent need to solve the urgent need to solve the urgent need to solve the urgent need to solve the urgent need to solve the urgent need to solve the urgent needs of the main control room and the radio station are not in the same place, the distance between the antenna installation location and the main control room exceeds the maximum length specified by the antenna feeder, and the emergency The problem is specially developed. The independent frequency selection shortwave radio remote equipment connection is simple, and the expansion function is rich. The system can remotely connect the shortwave radio control part with the shortwave radio through the IP network/optical fiber line.

2. The basic application of independent frequency selection shortwave radio remote system

1), the remote application of the shortwave radio set up on the top of the building and the communication command room inside the building

The antenna of the shortwave radio station is generally required to be erected at the commanding height position on the top of the tall building without surrounding obstacles to achieve a good communication effect. However, the communication room or command center where personnel operate and use the radio is often not in the same place as the antenna installation point that can exert good communication effects, and the distance exceeds the length range specified by the antenna feeder, so a set of equipment in the middle is needed to realize the man-machine of the radio station. The interactive part is remotely connected to the shortwave transmitter station at the antenna installation site through the network to realize the separation of man and machine, remote control, and real-time feedback of various status information of the transmitter station. 400YK independent frequency selection shortwave radio remote equipment can be conveniently through the internal network To achieve this function, the use of a software display interface that is more convenient to operate and exactly the same as the radio station has solved this problem.

2) Unified control application of shortwave radio in the communication command vehicle

Conventional small communication command vehicles and command centers are equipped with shortwave, ultrashortwave, satellite and telephone systems as the basic communication guarantee. These voice communication methods have their own characteristics and coverage, and they also have their own communication blind spots. By combining these This kind of communication equipment is connected to 400YK and performs system integration to realize the integrated communication of shortwave, ultrashortwave, satellite and telephone systems.

The PAD installed with 400YK independent frequency selection shortwave radio remote dispatch management software can be connected to the remote terminal on the final assembly cabinet of the communication command vehicle (usually at the rear of the vehicle) through a wired or wireless router, so that it is connected to the shortwave on the remote terminal , Ultra-short wave, satellite and telephone were taken over by 400YK. In the position of the co-pilot or console of the communication command vehicle, directly use the PAD to operate various voice communication equipment in the assembly cabinet to realize the separation of equipment access and control, which is convenient for managing the operation and communication of dispatchers during driving. The unified dispatch of the communication command system provides an effective solution.

3) The remote application of shortwave radio stations and underground bunker command posts set up at the commanding heights of cities

400YK also supports long-distance connection via optical fiber network. The independent frequency-selecting radio stations and antennas erected on the hilltops or commanding heights around the city can select standard IP optical transceivers (photoelectric conversion) according to different transmission distances through the optical fiber network of dedicated or leased operators. The connection of the city, the underground bunker or the communication command center at the other end of the city, through the computer or PAD 400YK dispatch command software for calls and remote control, provides a solution for the separation of the communication command system from the console and the launching station.

The 400YK self-selected shortwave radio station can also remotely control the power switch of the shortwave radio station and other peripheral devices, and can prevent the device from crashing or running away in long-term operation through remote real-time reset or timing reset. It is equipped with equipment that needs to be manually turned on. Artificial robotic arm, these functions ensure the long-term unattended and maintenance-free implementation of the shortwave radio transmitter (antenna erection point) far from the urban area. At the same time, the separation of the operator from the console and the launch pad greatly guarantees the safety of personnel in wartime and improves the ability of the shortwave communication system to resist damage.

3. Comprehensive application of independent frequency selection shortwave radio remote system

Directly control the receiving and sending of the shortwave radio station through the computer or PAD, adjust the parameters of the shortwave radio station, and feed back various status information of the shortwave radio station in real time.

8) 400YK equipment technical parameter list

TVS DIODE

Transient voltage suppression diode, also known as a TVS diode, is a protective electronic component that protects electrical equipment from voltage spikes introduced by wires.

TVS diodes are placed in parallel with the circuit to be protected. When its voltage exceeds the burst breakdown level, excessive current is directly shunted. TVS diodes are clamps that suppress excessive voltages that exceed their breakdown voltage. When the overvoltage disappears, the TVS diode automatically resets and absorbs much more energy than a similarly rated crowbar circuit.
