Intelligent civil air defense alarm system based on PDT digital trunking communication technology

Abstract

The invention relates to the technical field of civil air defense alarm, and discloses an intelligent civil air defense alarm system based on a PDT digital trunking communication technology, and the system comprises a PDT digital trunking communication network, a plurality of control centers, a plurality of environment monitoring units, and a plurality of alarm stations. The control center comprises a central controller and an alarm control server, and the central controller is electrically connected with the alarm control server; the alarm control server is in communication connection with the alarm station through a PDT digital trunking communication network; the environment monitoring unit comprises an environment acquisition module and an environment monitoring host, and the environment acquisition module is arranged at a monitoring position and is connected with the environment monitoring host; the environment monitoring host is in communication connection with the central controller through a PDT digital trunking communication network. The method can adapt to a complex electromagnetic environment, and faults of individual terminals cannot cause the system to work normally.

Description

technical field [0001] The invention relates to the technical field of civil air defense alarms, in particular to an intelligent civil air defense alarm system based on PDT digital trunking communication technology. Background technique [0002] Civil air defense, referred to as civil air defense, is the measures and actions taken by the government to mobilize and organize the people to prepare for enemy air attacks and eliminate the consequences, such as issuing and disarming civil air defense alarms. In wartime, it is responsible for the reporting task of guiding the masses to evacuate smoothly to prevent air raids; in peacetime, it is also responsible for the emergency reporting task of natural disasters and secondary disasters such as flood control and earthquake prevention. [0003] The civil air defense alarm system is an important part of the national defense system and emergency management system. Its working conditions directly affect the national war potential and ...

Problems solved by technology

[0004] However, the same-frequency and adjacent-frequency interference in ultrashort wave wireless communication is serious. Therefore, when individual devices in the ultrashort wave wireless network fail and are in a continuous transmission state, it is very likely that part or even the entire network cannot communicate normally.
