WSN (wireless sensor network) network-based anti-theft alarming device and alarming method of inspection well cover
By adding the reed switch approach switch, the device works only when the inspection well cover is moved, so that the energy consumption is saved and the working time of the device is greatly prolonged as a lithium thionyl chloride high-performance battery is used.
Abstract
The invention relates to a WSN (wireless sensor network) network-based anti-theft alarming device of an inspection well cover. The device comprises an alarm and a magnet, wherein the alarm comprises a shell, a triggering switch, a battery and a communication module, wherein the magnet is fixedly arranged at the back side of the inspection well cover; the alarm is fixedly arranged on the inner wall of the inspection well; the triggering switch is arranged within a magnetic range of the magnet; the triggering switch is of a reed switch approach switch; the communication module adopts a zigbee2.4GHz communication module; the battery adopts a high-performance battery; and the triggering switch, the battery and the communication module are arranged on a PCB (printed circuit board) in the shell. The invention also discloses an alarming method of the device. According to the device, a mode of mobile wireless transmission data GSM (global system for mobile communications), GPRS (general packet radio service) and CDMA (code division multiple access)) is replaced by the zigbee communication module, so that the power consumption is greatly reduced; by adding the reed switch approach switch, the device works only when the inspection well cover is moved, so that the energy consumption is saved; and the working time of the device is greatly prolonged as a lithium thionyl chloride high-performance battery is used.
