Electricity larceny prevention intelligent device

The present invention belongs to the field of electric meter box monitoring, and specifically relates to an electricity larceny prevention intelligent device. The device mainly comprises an intelligent module, two 485 interfaces, and a micropower wireless module. When a cabinet door is open, the intelligent device receives a cabinet opening signal, after a delayed alarm time, the intelligent device reports the cabinet opening event to the ammeter micropower wireless module, and the ammeter micropower wireless module uploads the event to a concentrator main meter reading module, and then the event is transmitted to a concentrator station, and is finally transmitted to a master station. The device is installed in an ammeter cabinet. Work personnel can use a special Bluetooth device to communicate with the intelligent device, so that the cabinet opening event is not uploaded as an alarm event. The device is internally provided with a battery, and the device can record information of opening-closing events of the cabinet door of a metering cabinet when an external line is power off.
