4. Public health events: mainly includes the epidemic situation of infectious diseases, group unknown cause disease, food safety and occupational hazards, animal epidemic situation and other serious influence public health and life safety event;
When sudden public events occur, the emergency communication command system often assume the responsibility of the communication network. When emergency communication command vehicle arrived after the event, we can quickly build up the communication network system, collect the visual/audio, data and information, and accept the superior to the command, scheduling and guidance. The emergency communication command system load function often becomes public emergencies successfully resolved the key factor.
Two, the function overview
Emergency communication command system is a rapid response communication system and information system integration platform, integrated all sorts of emergency service resources, unity of command, joint action, for citizens to provide rapid, timely emergency rescue service for the public safety of society to provide a strong guarantee. Has been widely used in government, public security, armed police, army, civil air defence and fire, banking, energy, meteorology, earthquake, etc.
Site emergency communication command system main function is as follows:
The information acquisition function. Usually emergency cases, emergency most appear in the environment very complicated city or remote areas, emergency communication command vehicle system can only reach near the scene of the area for emergency decision and command scheduling communication. At this time, communication command vehicle except at various levels and the competent department command center set up information real-time transmission between the interaction, at the same time also need to provide emergency first field and field headquarters (emergency communication command vehicle) audio/video, data transmission channel. Acquisition event occurred the geographical position information, image information, audio information, environmental parameters, such as information;
Foreign communication function. Through the 350 MHZ radio, or may use the GSM, CDMA, WCDMA, WiMAX mobile phone to the command and dispatch.
The image access and display. Communication command vehicle image information directly from the site, the amount of information is bigger, because upload communication link bandwidth restricted, cannot at the same time will be multiple image access at all levels of the department in charge of emergency command center. Thus, communication command vehicle configuration baimiao display, audio and video switching matrix, storage equipment, for the real-time display and record the site condition to use.
Intelligent decision. With the site condition real-time monitoring, display, analysis, comprehensive treatment function, for the event handling, emergency command to provide decision-making basis. The relevant application system for commander informed of the incident development situation, check all of the data gathering field audio/video and read the history data and emergency plan and make a command decision to provide the platform.
Three, the technical implementation

Emergency motor command communication vehicle system by the vehicle system, communication system, computer and integrated control system, field monitoring and video transmission system, strong lighting system, broadcasting system, power system, conference system, warning system, multi-function bearing car frame system composition.
Four, the application and the customer benefit
Emergency motor command communication car is fixed command center expansion and extension, able to the scene of the incident quickly feedback to the competent department command center. Can be used as emergency field emergency command communication center, near the scene of the event constitute the command platform for each site and provide support for the government emergency decision and command provide rely on, further improve the governments at all levels capable of responding to emergencies.
Five, involving the product
Emergency communication command vehicle, COFDM transmission equipment, telephoto camera (focal length 10-300 mm, 500 meters monitoring).
