Problems solved by technology
This calibration method wastes a lot of time in raising the power supply, switching the power supply, waiting for the power supply to stabilize, and waiting for the error meter to produce an error, especially for small signal power calibration. It takes a few minutes to wait for the error meter to produce an error. The workload of one person is about 90. -120 pcs / hour

The present invention discloses an automatic meter-calibration method for a single-phase electric energy meter production line, wherein a verification device is adopted. The hardware of the verification device comprises a single-phase standard meter, an error detector, a single-phase power supply, a state grid single-phase electric energy meter bracket, an air pump power source crimping device and a platform control module. The automatic meter-calibration method comprises nine meter calibration steps. According to the technical scheme of the invention, the calibration speed of electric energy meters is improved and the yield is increased. Meanwhile, the time-of-day clock error and the electric quantity error of electric energy meters are accurately calibrated. The basic parameters of electric energy meters can be verified, and common hardware problems can be found out. The production process of electric energy meters can be tracked. Moreover, during the calibration process of electric energy meters, key parameters can be recorded and data can be tracked. In case that the power supply is not switched, the errors of electric energy meters are calibrated according to power. Therefore, the switching time and the waiting time are reduced.
Description
technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an automatic meter calibration method for a single-phase electric energy meter production line. Background technique [0002] At this stage, most of the electric meter manufacturers use a 48-meter virtual serial port calibration platform for the calibration of single-phase electric energy meters, and perform error verification on single-phase electric meters in six steps. The verification process in this way has many inconveniences, wastes a lot of time, and increases bad examples. [0003] In terms of production process, the traditional production process is that after the watch is assembled on the assembly line, the watch is transported to an independent debugging workshop for calibration, and after calibration, the watch is transported to the aging workshop for aging. This method of independent debugging workshop, a lot of time is wasted in transportation, loos...
