The invention discloses a damaged single-phase intelligent electric energy meter electric quantity data extraction device. The device comprises a single chip microcomputer circuit which is connected to a button circuit, an SOP8 foot BIOS clamp circuit, an RS485 circuit, an FLASH memory circuit, an LCD display circuit, and a power supply circuit. When a fire occurs in a user site due to line lightning stroke, line aging, loose wiring screw loosening, poor contact and the like, a terminal and an internal circuit of an intelligent electric energy meter are damaged because of burning, a damaged single-phase intelligent electric energy meter can not work, and operation and maintenance personnel of a power supply department can not obtain electric quantity data of the damaged single-phase intelligent electric energy meter in the site. By using the device of the invention, the damaged electric energy meter can be processed in the site and the electric quantity data of the plurality of single-phase intelligent electric energy meters can be extracted and sent to a far end so as to find out a deeper fault reason. The site work difficulty of a power supply management department is mitigated and the operation and maintenance cost of an intelligent electric energy meter production enterprise is reduced.
Description
technical field [0001] The invention belongs to the field of smart grid, and relates to a device for extracting electric quantity data of a single-phase smart electric energy meter damaged on site and an operation method thereof. Background technique [0002] The single-phase smart energy meter has the functions of forward active power and reverse active power measurement; it has the functions of total, peak, peak, flat and valley time-sharing measurement; it has the function of recording the total power and each tariff for 12 settlement months; 254 hourly freeze power data recording function. These different types of electricity data can be read through the communication interface and directly viewed on the LCD display of the single-phase smart energy meter. Because of the obvious advantages of smart energy meters, more than 400 million smart energy meters have been installed at present, basically achieving comprehensive coverage. However, the popularity of single-phase s...
