Introduction to the urban major emergency rescue system

China has a vast territory, many mountainous areas, and the environment is more complicated. In recent years, abnormal weather such as typhoons and heavy rainfall frequently occur, and the economic losses and casualties caused by bad natural disasters are not optimistic every year. In order to effectively reduce the damage caused by harsh nature and ensure the safety of personnel, the urban emergency rescue command communication system is indispensable.

The emergency rescue system function must meet the following points

1. Multi-network integration: Integrate wired network, operator public network 4G, municipal private network 4G, fire private network 4G, MESH network, satellite network and other networks to form a comprehensive communication network with full coverage and no blind zone. One kilometer of network communication blind zone ensures smooth communication of voice, video and data.

2, multi-level command: to achieve voice scheduling, video scheduling, data scheduling, GIS scheduling and large-screen scheduling, geographical connection accident scene, front and back, vertical construction of multi-level (site, detachment, corps, ministry, etc.) command and dispatch The system, horizontally collaborating with the government, transportation, health and other departments to form a comprehensive emergency command and communication platform covering all aspects of command.

3. Multi-data integration: Integrate a variety of data information, comprehensively integrate air call, vital signs, location tracking, environmental detection, individual video voice and fire service system data, and realize alarm linkage with emergency communication system Linked with the command.

4, multi-resource scheduling: comprehensive linkage of multiple information system platforms, to achieve emergency / normal, flat / war combined people, vehicles, equipment, materials and other comprehensive command and control and management.

Emergency rescue system consists of:

1. Front end - patrol camera + walkie-talkie: used to monitor the running status of the patrol car in real time and report the voice to the scene environment.

2, the middle end - mobile transmission equipment: common COFDM mobile wireless video transmission equipment, single-armed wireless video transmission equipment, portable wireless video transmission equipment, handheld terminals.

3, back-end - monitor display + hard disk recorder (NVR) + walkie-talkie: used to display and store surveillance video images, as well as command orders for patrol cars and front-end rescue personnel.

The city's major accident emergency rescue system plays a key role in the smooth operation of accident and disaster relief work, and is an important guarantee for ensuring the efficient implementation of disaster relief emergency command work and ensuring the safety of urban people and property.
