Abstract

The embodiment of the invention discloses an electric energy meter, an electric energy meter calibration device and an electric energy meter calibration method. The electric energy meter comprises a first wireless communication module, a second wireless communication module and a data processing module, the first data processing module is used for converting a preset calibration pulse signal intoa calibration data packet; the first wireless communication module is used for handshaking with the electric energy meter calibration device based on a preset standard protocol and configuring a preset transmission parameter between the electric energy meter and the electric energy meter calibration device; and the second wireless communication module is used for sending the calibration data packet to the electric energy meter calibration device at a first delay time based on a preset transmission parameter, so that the electric energy meter calibration device determines the to-be-calibrated parameter of the electric energy meter according to the calibration data packet, and the first delay time is less than the minimum delay time for data transmission based on a preset standard protocol.According to the technical scheme, real wireless meter calibration can be realized, one-to-one calibration of the electric energy meter and the electric energy meter calibration device can be realized, and the anti-interference performance is high.

Description

technical field [0001] The invention relates to the technical field of electric energy meter calibration, in particular to an electric energy meter, an electric energy meter calibration device, a meter calibration station and an electric energy meter calibration method. Background technique [0002] At present, electric energy meters on the market widely use wired RS485 interface to realize remote meter reading. Since the energy meter needs to send a calibration pulse to the meter calibration station for calibration of the energy meter before leaving the factory, a pulse interface for transmitting the calibration pulse signal is usually set on the energy meter. This method needs to arrange a large number of communication cables, the cost of production and testing is high, and the construction and production testing are troublesome. [0003] With the promotion of Bluetooth low-power technology, some Bluetooth energy meters have appeared on the market, but ordinary Bluetooth ...
