Urban emergency wideband communication system on the basis of temporary communication resource

Abstract

The present invention provides an urban emergency wideband communication system on the basis of a temporary communication resource. The system provided by the invention comprises an emergency communication management center, a portable wireless self-organization communication device, a control box configured to receive center control signals and control a local device and a signaling channel. The emergency communication management center is composed of a server and application software and a management agency communication device, and the portable wireless self-organization communication device is connected with the emergency communication management center through the signaling channel. Answering alarm people provide an application of starting the urban emergency wideband communication system through the wireless self-organization communication device; the emergency communication management center is configured to calculate an urban emergency wideband communication system organization scheme according to an alarm position and an incident position; incident scene image information is reported to the emergency communication management center through the urban emergency wideband communication system, and the emergency communication management center provides required communication channels; and the system is closed after the disposition of the emergency is finished, and temporarily borrowed frequency resource is released.

Description

technical field [0001] The invention belongs to the field of overall system design, in particular to an urban emergency broadband communication system based on temporary communication resources. Background technique [0002] Urban emergency response involves multiple ministries and commissions such as public security, armed police, medical rescue, transportation, and fire protection. On-site images during emergency handling, as the most important source of command information, are always urgently needed by command posts at all levels and types when emergencies occur. The most direct information obtained is an important basis for command and decision-making. However, due to the uncertainty of the time, location and nature of the emergency, the pre-arranged mode is difficult to meet the business needs during the emergency, and wireless, as a fast networking and service provision mode, is very suitable for the unknown situation in advance Therefore, the wireless method has bec...

Problems solved by technology

However, due to the uncertainty of the time, location and nature of the emergency, the pre-arranged mode is difficult to meet the business needs during the emergency, and wireless, as a fast networking and service provision mode, is very suitable for the unknown situation in advance Rapid system construction, so the wireless method has become the main technical means of emergency scene image transmission

[0003] However, due to the limitation of wireless resources (frequency) and technical problems such as wireless broadcast transmission, multi-channel high-definition wireless image transmission and reporting at the scene of the incident has always puzzled the designers of emergency systems, how to obtain more available wireless resources, and How to solve the problem of wireless communication occlusion in the city (such as places such as basements) has become an urgent problem for urban emergency services, and the present invention will solve these problems that have plagued the emergency command system for many years

[0004] Judging from the current situation, the public security, armed police, and firefighting have all built their own wireless image transmission systems, but due to frequency resources and networking issues, only 1 to 2 channels of standard definition (or even lower standard) image transmission can be realized. And in the work, it is often blocked by various terrains and buildings in the city, so it is impossible to achieve high reliability of emergency communication. The reason is that the fixed allocation mode of wireless communication frequency and bandwidth, as well as single or several fixed access points Insufficient wireless coverage for
