The real-time information interaction between the accident scene and the dispatching command center is the key technology of emergency rescue dispatching command, and it is also a research hotspot in recent years. In other application fields of emergency rescue, such utility model patents have been applied for in recent years. In 2007, Shaanxi Haohan Xinyu Technology Development Co., Ltd. applied for "an underground emergency rescue wireless communication system and establishment method based on short-distance wireless communication (SDR) technology" (patent application number: 200710018358.7), using the method of short-distance wireless communication , to quickly and accurately obtain the key information data and on-site status information of the disaster site, so that the rescuers can organize and implement the rescue work, but this utility model cannot exchange information with the remote dispatching command center, so only the experience of the on-site rescuers The problem of emergency rescue. In 2008, Beijing University of Aeronautics and Astronautics applied for the "Airport-oriented Emergency Rescue Vehicle Dispatch and Command System" (patent application number: 200810104093), which uses GPRS to collect the basic information of surrounding rescue vehicles, and sends them to the dispatch command center in a timely manner through the GPRS network. Information feedback, with the popularization of 3G network and its compatibility with GPRS network, GPRS has been gradually replaced by 3G network. This patent is mainly used in emergency rescue for airports, but not in the field of emergency rescue for road traffic accidents.

It has an irreplaceable role and has played a huge role in emergency rescues such as floods, earthquakes, snow disasters, and fires. the

To sum up, 3G or GPRS networks cannot meet the requirements of complex traffic environments, and it is expensive to use maritime satellites for information exchange, which is not suitable for popularization and application. Therefore, the utility model utilizes the effective combination of these two communication modes, and utilizes the redundancy and complementary characteristics of different communication modes, so as to ensure the reliability and robustness of information exchange in emergency rescue. the
