| Zusammenfassung: | The invention provides a verification method of an intelligent electric energy meter. The verification method comprises the following steps that S10, a master Bluetooth module and a slave Bluetooth module carry out initialization time synchronization; S20, after the verification is started, the master Bluetooth module and the slave Bluetooth module carry out time synchronization once every 8-12ms until the verification process is finished; S30, after verification is started, a to-be-verified electric energy meter sends a pulse signal to the slave Bluetooth module, and the slave Bluetooth module sends the serial number of the received pulse signal and the time information of the received pulse signal to the master Bluetooth module; S40, the master Bluetooth module receives the information transmitted by the slave Bluetooth module, performs electric energy error calculation on the information, and sends a calculation result to a display unit; and S50, the display unit displays the electric energy error result. |
