Embodiment Construction

[0011] in figure 1 Shown: the external interrupt pin (INT0) of the main control MCU IC1 (ATMEGA16) is connected to the door sensor switch (J1) and connected to the ground via R5. The reed magnetic switch is fixed at the opening and closing of the meter box door, the meter box is opened, the meter box is opened, the door magnetic switch (J1) is turned on, the interrupt pin INT0 of (ATMEGA16) becomes high, and the master MCU IC1 detects After the door open signal, the main control MCU IC1 (ATMEGA16) drives the buzzer (BELL) to prompt the meter reader to enter the password. The meter reader uses K1 / K2 / K3 / K4 to form a keyboard circuit to input the password, the password is wrong or the time exceeds the limit. The main control MCU IC1 (ATMEGA16) drives the buzzer (BELL) to generate an alarm signal and sends the alarm information through the wireless transmitter module.

[0012] The pins (TXD / RXD) of the master MCU IC1 (ATMEGA16) are connected to the wireless transmitter module (RF) r...

Abstract

The invention provides a wireless alarm and record device for the opening of an electric meter box, which is used for preventing unauthorized opening of the electric meter box, and is applied to power supply enterprises. The device is composed of: a door magnetic switch, a microcontroller, a wireless transmitter module, an LCD, buttons, a buzzer, and a power supply. The working process of the device is as follows: the microcontroller detects the door magnetic switch; when the door of the electric meter box is open, the door magnetic switch is separated, and the microcontroller records the box-opening time and prompts for password entry; a meter reading worker enters the password of the worker his own via buttons, and if the password is right, the microcontroller records the operator; and if no right password is provided within a set time, the opening is counted as unauthorized opening, so the microcontroller generates an alarm sound, and transmits a signal to a wireless remote meter reading network of a power supply enterprise through the wireless transmitter module. The beneficial effects of the device are: by using the existing wireless meter reading system of the power supply enterprise, remote real-time online monitoring and recording electric meter box opening statuses can be realized, thereby facilitating the supervision and management of electric meter boxes for power supply enterprises, preventing behaviors of stealing electricity and reducing power losses caused by bad behaviors of human.

Description

Technical field [0001] The invention relates to a wireless anti-theft recording and alarm device, which is applied to power supply enterprises to prevent illegal opening of electric meter boxes. technical background [0002] Preventing electricity theft and reducing line losses have always been problems faced by power supply companies. In order to reduce costs, some companies use various channels to equip the meter box key to open the meter box to steal electricity. Discriminating whether the meter box is opened illegally is an effective means to prevent the theft of electric energy, such as the public number: CN101369353A, the anti-theft opening recorder. Using electronic lock and radio frequency card authentication technology, each meter box is equipped with an electronic lock. The cost is very high. At the same time, the electronic mechanical lock is exposed to the wind and sun, and the mechanical components are prone to oxidation and rust, so this product is difficult to app...
