With the gradual development of the society, the fire and emergency accidents also enter into a rapid growing phases. The loss caused by the accident is far higher than the national growth rate. Since the beginning of this century, China's major or fatal fires, mine explosions, earthquakes and toxic leaks and other accidents occur frequently and directly endanger people's lives and property, which seriously affect the country's sustainable development strategy and social stability.

In recent years, as the urban construction expanding and skyscrapers erected, the chemical industry growing rapidly and large markets, shopping malls and public places of entertainment could be seen everywhere. In this new situation, the fire accident also appears to complicated with a variety of new features, such as fire, explosion, poisoning, etc. are often happened simultaneously. From the object view, the object from a single unit to comprehensive, from one to many. Take the modern chemical enterprise as an example, it has complicated technique and modernization equipments, and also each workshop has storage of different inflammable and explosive chemicals. Especially the pipeline is very complex, once the fire happened, it will be easily spread like the chain. Take public places as another example, it's very obvious that it increase to be large-scale trend in recent years. The shopping malls, restaurants, hotels, dance halls and other large buildings tend to be concentrated in the same place with luxurious decoration and complex layout, the channel twists and turns complicated and flammables objects everywhere. Once it's fired, it needs a lot of site information for command and decision.

View from the fighting conditions, the urban fire facilities are growing and spread over the street. Also the fire sites, vehicles and equipment also increasing rapidly day to day. So the scientific management and rational management of fire vehicles and equipment facilities is especially important nowadays.

At present, the equipments for dispatch are mainly for the radio communications, the dispatch center sent out orders to the driver of the vehicle, and the driver can only speak the location according to their own judgment. If the location of vehicles is unfamiliar or at night, or even lost, it will surely miss the best time to fire fighting.

Therefore, how to effectively restrain the rapid development of fire accidents and reduce fire losses, timely processing and transmission of fire-fighting command information, scientific control of use of existing equipment, manpower, resources, and comprehensive information resources, and take reasonable and effective measures to prevent and eliminate fire has become an increasingly important task.

Network topology
Benefits from the entire system based on Hiinfo onboard computer, which has the powerful, scalable hardware platform. The core is the onboard computer and through the wired and wireless IP networks, to realize the real-time monitoring of fire engines, and the management and spot command of vehicle information. Meanwhile, the system could use the Internet link (2.5G, 3G, Wi-Fi or maritime satellite) channel to set up physical link between the vehicle and command centre to construct a complete network.

System function

Aim at the logistic drivers, the system offers the following features
·Video Surveillance
·Automatic Report
·Live video capture
·receive remote control
·Automatic navigation

For command and control center, the system provides the following features
Fire engine location query / Fire Trading Data Query
Traffic data query / alarm display
History track playback / Map Maintenance
Voice monitoring / remote vehicle control
Fire vehicle scheduling / traffic video monitoring
Fire Vehicle Information Inquiry

Technical Framework
The system adopts stratified modular system design. The technical platform offers GIS, database, WEB, middleware and other basic software applications to provide run support environment. The application products (car computer, WEBGIS scheduling navigation systems, video surveillance systems) could be integrated and constitute the onboard computer as the core in the car to provide fire industry solutions.

Vehicle information system technology
In-Vehicle Information System (Car PC) combined with the car electronics and embedded computer technology, which applies the computer technology to the vehicles application, which connect the computer with the automotive power, sensors and other related control signals, and forms an open information processing platform to provide GPS positioning and navigation, digital instrumentation, fault detection, wireless network communication, multimedia and entertainment features to enhance the level of the car information level, safety driving and entertainment.

WEBGIS Technology
This is a new structural model of the network geographic information technology. The system structure design is more emphasis on display and processing ability; It adopts the network programming tools (Java language) to develop and the running program is less than 100kb which is convenient for network transfer. The whole system adopts the clients and server distributed processing model, the multi-vector data solutions solve the problem of narrow bands transmitting huge amounts of data which can greatly improve customer access speeds and lower system investment costs. The client and the server also provides the secondary development interface respectively.

Video surveillance technology
The system adopts the multi-channel video surveillance which could install system, installed in the car inside and outside the various high-speed video camera, which can store all graphics locally in each position. Through optimized compression algorithm for compressed video signals, it will upload to the military control centre through the internal network. The Command and Control Center will decompress the video data and display of multiple video signals to issue orders depending on the road condition.

3G Wireless Video Surveillance
By 3G wireless network, it will collect the real-time image data and transmit to the remote command center, which will help the command center to know the actual situation and make proper judgments. Meanwhile, it could effectively deploy the resources depending on the actual situation, and rapidly respond to control the situation. Based on onboard computer, it provides full ranges of remote surveillance functions for the remote online user. With professional, personalized, humanized software features, it can influence the centralized surveillance system in the customized, compatibility, stability aspects.

It¡¯s very influential to promote this solution in the fire-fighting industry. This solution used many advanced technologies and achieving seamlessly command from the control center to fire engines, which greatly improves the speed of fire fighting system and management efficiency, standardized the fire system procedure. The system has a powerful 3G navigation function to provide long-term instructions and location services for the fire vehicles in the disaster site, and also enhance the working efficiency and save time. This system is advanced, simple, stable, great expansibility with high values, which will surely enhance the information level of fire-fighting industry.
