Design of the pre-device for the online inspection and fault diagnosis in gateway electrical energy metering device
There are some problems too difficult to solve traditionally existing in the remote calibration and online diagnosis of the gateway electrical energy metering device. A new method is introduced to design the pre-device for the remote calibration and online fault diagnosis in the gateway electrical energy metering device. In this design, the local time domain waveform data of current and voltage can be acquired by the high-precision sampling circuit based on GPS synchronous sampling and wireless communication. These data are uploaded to the master station server by the wireless network composed of WIFI modules. In the master station server, these data are processed with the algorithms of energy calibration and model statistic optimization to realize the online inspection and fault diagnosis of the electric energy tariff point metering device. Thus the level of supervise management along with the remote calibration and online diagnosis can all be improved in the gateway electrical energy metering device.
