Internet-of-things lock for electric energy meter metering box

Abstract

An internet-of-things lock for an electric energy meter metering box comprises the electric energy meter metering box and an electronic lock, an MCU, an ESAM safety module, a Bluetooth module, a positioning module, an RS485 communication module and a power supply unit are installed in the electric energy meter metering box, and the electronic lock, the ESAM safety module, the Bluetooth module, the positioning module and the RS485 communication module are connected to the MCU; the MCU can control the electronic lock to lock and unlock the box door of the electric energy meter metering box; the ESAM safety module can be matched with the MCU to realize safety control of locking and unlocking processes; the Bluetooth module can receive locking and unlocking commands of a mobile phone terminal; the positioning module can send position information to the MCU; the RS485 communication module is communicated with other devices installed in the electric energy meter metering box through an RS485 bus. The electric energy meter metering box is knowable, controllable and measurable, and information can be uploaded through the RS485 module for analysis.

Description

technical field [0001] The invention relates to the technical field of electric energy meter metering boxes, in particular to an IoT lock used for electric energy meter metering boxes. Background technique [0002] As a key link in the distribution network, the electric energy meter metering box is not only the "protective shell" of electric energy metering equipment, carrying massive data of various electric power information, but also the power grid enterprise providing security for hundreds of millions of residential customers and the vast number of small and micro industrial and commercial users. The smallest unit of reliable power supply service is the demarcation point of property rights between the power grid and user equipment, and is an important bastion related to the safe and reliable power consumption of thousands of households. Its operation safety, reliability, and information utilization are particularly important. However, at present, the safety sealing perfo...

Problems solved by technology

[0003] For example, the Chinese invention patent 201811600486.7 proposes a multifunctional electric meter box smart lock system. Although it can verify the identity and unlock and has communication functions, it cannot realize the environmental status perception, monitoring and early warning of the electric energy meter meter box. For the electric energy meter meter box Various problems exist, and it is necessary to innovate and develop an intelligent IoT lock that integrates equipment perception and monitoring and early warning technology to realize online reliable management of electric energy meter metering box access control and real-time monitoring and early warning of electricity theft abnormalities, thereby greatly reducing the management and operation of the station area. The existing workload of the staff can effectively improve the work efficiency and data accuracy, and effectively promote the lean management of the station area to a new level
