Box opening carrier wave alarm reporting device of electric meter box

Abstract

The invention discloses a box opening carrier wave alarm reporting device of an electric meter box. The box opening carrier wave alarm reporting device of the electric meter box is applied to power supply enterprises and is a device which prevents the electric meter box from being opened illegally. The box opening carrier wave alarm reporting device of the electric meter box is composed of a door magnetic switch, a single chip computer, a carrier wave communication module, a liquid crystal display (LCD), a button, a buzzer and a power supply. The working process is as follows. The single chip computer checks the door magnetic switch. When the electric meter box is opened, the door magnetic switch is separated, and the single chip computer records box opening time and shows to input a password in set time. A meter reading person inputs the password through the button, the single chip computer records an operator if the password is right. When a right password is not provided in the set time, opening of the electric meter box is illegal. The single chip computer is driven to make alarm sounds. Alarm signals are sent to a carrier wave remote meter reading network of the power supply enterprises through the carrier wave communication module. The box opening carrier wave alarm reporting device of the electric meter box has the advantages that remote, real time and online monitoring and recording opening conditions can be carried out by using the carrier wave remote meter reading network of the power supply enterprises. Convenience is brought to the power supply enterprises to monitor and manage the electric meter box. Sealing electricity behaviors are prevented. Man-made electric energy loss is reduced.

Description

Technical field [0001] The invention relates to a carrier wave anti-stealing electric recording alarm device, which is applied in power supply enterprises to prevent illegal opening of electric meter boxes. technical background [0002] Preventing electricity theft and reducing line loss has always been a problem faced by power supply companies. In order to reduce costs, some companies have equipped the meter box key through various channels to open the meter box to steal electricity. Discriminating whether the electric meter box is opened illegally is an effective means to prevent the theft of electric energy, such as the anti-theft electricity unpacking recorder of CN101369353A. Using electronic lock plus radio frequency card authentication technology, each watch box is equipped with an electronic lock. The cost is high, and at the same time, the electronic mechanical lock is exposed to the wind and the sun outdoors, and the mechanical components are easily oxidized and r...
