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.
