Intelligent calibration system of operating panel relay of low-voltage microcomputer protection and monitoring device

The invention relates to an intelligent calibration system of an operating panel relay of a low-voltage microcomputer protection and monitoring device. The intelligent calibration system of the operating panel relay of the low-voltage microcomputer protection and monitoring device comprises an upper computer and a single chip microcomputer monitoring device. Calibration software runs in the upper computer. The single chip microcomputer monitoring device is connected with the upper computer and produces at least two direct-current current signals and at least one direct-current voltage signal under the control of the upper computer. The single chip microcomputer monitoring device is connected with an operating panel so as to achieve connection of the intelligent calibration system and a relay to be calibrated. The intelligent calibration system adopts a method for connecting the relay to a calibration simulating circuit to perform automatic calibration on the relay. All of relays on the operating plate of a typical relay protection product can be accurately calibrated, and the intelligent calibration system can be widely applied to production and debugging of a relay protection device and can remarkably improve the testing accuracy and safety.
