In the face of all kinds of unexpected events, large-scale activities of security, natural disasters, etc., if the lack of efficient emergency system, will give social production, life and social stability caused great losses and adverse effects. Emergency communication system is an important part of the whole government emergency command system, it is an effective extension of the emergency command ability of government agencies, and can realize the emergency command and dispatch. Comprehensively solve the government emergency scene real-time monitoring, video / image transmission. Data transmission, multi - mode communication network interconnection and field command scheduling.
According to the actual demand, a public security unit needs to build a wireless emergency command system, that modular product is integrated in the vehicle terminal equipment, so as to improve the response speed of the incident. Command center is located in the office building, through the erection of a wireless base station, wireless signal coverage. Emergency command vehicle through the wireless device to the vehicle's audio and video signal real-time transmission to the command center, the transmission distance is greater than 20km. In the special environment, need to use individual equipment, through the vehicle relay mode, the wireless transmission distance between individual equipment and communication car, that requirement of more than 5km.
The 3onedata products are mainly used in wireless base station wireless receiving device and the front command vehicle terminal, that the IEM605-2D module is integrated into the vehicle terminal and base station communication device, that fast Ethernet port connection wireless antenna, decoder and camera, that the serial port for debugging equipment and vehicle controller. The whole emergency command system uses the wireless communication mode which the base station group covers the whole working area, which constitutes the internal wireless LAN, fast, reliable, safe and stable operation. Emergency communications vehicles equipped with wireless transmitter terminal equipment, the field of video and voice sent to the base station, the base station to send data to the command center and monitoring center, complete unified scheduling and monitoring.
