Abstract

The invention relates to the technical field of power system control, particularly to a remote intelligent verifying device and a method of a voltage monitor based on the GPRS / GSM network. The device comprises a terminal executive unit, a server unit and a human-computer interaction interface. The verifying device is provided with a sole data pass back function and can pass standard voltage data of the verifying device back solely, the server compares the data passed back by the verifying device and data pass back by the voltage monitor, and errors of the two sets of data can be checked more intuitively. The detection accuracy is high, staff do not need to verify the monitor in installation sites of the voltage monitor, a large amount of time is saved, workload is reduced, and efficient monitoring of the voltage monitor for quality of grids is guaranteed.

Description

technical field [0001] The invention relates to the field of power system control technology, in particular to a remote intelligent calibration device and method for a voltage monitor based on a GPRS / GSM network. Background technique [0002] With the wide application of voltage monitoring and testing instruments, in view of the fact that the voltage monitoring instrument may have inaccurate detection defects after a period of time, it needs to be calibrated frequently, which requires a special person to calibrate it. However, with the increase in the number of voltage monitors used, the labor cost will also increase. In addition, the calibration period is short, which will increase the workload of the staff, and sometimes some instruments may not be calibrated in time. This may prevent the power company from obtaining real power supply quality information in real time, and may also affect the user's power quality. Contents of the invention [0003] The present invention ...
