Railway wagon wireless warning method and warning system based on ZigBee

Abstract

The invention discloses a railway wagon wireless warning method based on ZigBee. Carriage ZigBee equipment nodes are arranged above each wagon carriage door, a wireless sensor network is built, a ratio frequency card is adopted for writing the media access control (MAC) address of the ZigBee equipment nodes arranged on each carriage into the radio frequency card, the carriage number and the MAC address of the ZigBee equipment nodes can be statically bound, in addition, the carriage number can be correctly displayed on a hand-held terminal, a door magnetic sensing circuit is arranged on each carriage door for collecting the door state switch quantity signal, the ZigBee equipment nodes corresponding to the opened carriage door generate warning information when the carriage door is illegallyopened, the warning information is uploaded to a ZigBee coordinator through a wireless network, and the warning information is displayed on the hand-held terminal interface. The method is suitable for conditions with freely increased and decreased carriages, the operation by nonprofessional personnel is convenient, the carriage number is convenient to modify, safety and reliability are realized, the invasion of illegal personnel into the wagon carriage can be timely discovered, in addition, railway workers are prompted to adopt measures for processing through the warning, the labor and the materials can be greatly saved, the efficiency for fighting against the crime of stealing can be improved.

Description

technical field [0001] The invention relates to a ZigBee-based wireless alarm method and alarm system for railway freight cars. Background technique [0002] For a long time, the theft of railway wagons has been a frequent criminal case on the railway. It not only seriously violated the property safety of the majority of cargo owners, but also caused very large economic losses to the railway enterprises, damaged the reputation of the railway enterprises, and sometimes even caused serious damage to the military of the country. , science and technology, diplomacy, etc. have a bad impact, especially the consequences of the theft of some trucks will seriously endanger the safety of train traffic. [0003] The methods to prevent the theft of railway wagons include the use of duty personnel to inspect, install anti-theft door locks or electronic monitoring devices, etc. In the electronic monitoring devices of railway wagons, there is a video monitoring method, that is, monitorin...

AI Technical Summary

Problems solved by technology

However, due to the mobility of railway wagons, there will be increases or decreases in goods, increases or decreases in carriages, and changes in carriage numbers at different stops, which makes the above-mentioned monitoring methods inconvenient.
