Subway environment monitoring system based on ZigBee and GPRS

Abstract

The invention relates to a subway environment monitoring system based on ZigBee and GPRS. A ZigBee terminal monitoring node collects environmental parameters in a subway tunnel, and the environmentalparameters are forwarded and transmitted to a coordinator through ZigBee wireless communication; the coordinator realizes conversion of a network protocol with a GPRS communication module; and finally, the data is transmitted to a remote monitoring center through the GPRS communication module, and the remote monitoring center can monitor on-site environment in real time, and can also send a command to control the whole system. The subway environment monitoring system is low in cost, high in flexibility and energy saving and environmental friendly, and is of great importance to ensure safe operation of the subway and improve management efficiency.

Description

technical field [0001] The patent of the present invention belongs to the field of environment monitoring, especially a subway environment monitoring system based on ZigBee and GPRS. Background technique [0002] The underground railway transportation system, referred to as the subway, is the extension of the railway in urban public transportation, and it is also the product of the development of the city to a certain extent. It makes full use of the underground space of the city, without hindering various ground buildings and destroying the ground landscape. Under the circumstances, the problem of large passenger flow transportation in the city is solved in a convenient and high-speed way. The rapid increase of modern urban population leads to the increase of vehicles, which brings a series of problems such as traffic congestion, environmental pollution and energy crisis to the city. Now the world's population exceeds 6 billion, and the number of cities with a population o...

Problems solved by technology

[0004] With the rapid development of urban rail transit, the subway has brought great convenience to the travel of residents, but during the operation of the subway, man-made or natural disasters may also occur, such as fires, poisonous gas, earthquakes, etc. These subway safety accidents will cause Huge economic losses, even casualties

In the traditional subway monitoring solution, the monitoring point adopts wired access, the construction and maintenance costs are high, and the system scalability is poor
