System and method for mass production and testing of electric power monitoring instrument

Abstract

The invention discloses a batch production test system for electric power monitors, which comprises: a processing terminal, a power source, a measurement and control module, a connection module, a hub, a scanner, a detection switch and an indicator light; the power source is connected to the electric power measurement and control instrument through the connection module , the power measurement and control instrument communicates with the processing terminal through the hub, and the power source and the output module communicate with the processing terminal through the serial port. One end of the detection switch is connected to the common terminal of the measurement and control module, and the other end of the detection switch is connected to the DI interface of the measurement and control module. The indicator light is connected to the DO interface corresponding to the DI interface, and the scanner is connected to the processing terminal. The invention also discloses a mass production and testing method of the electric power monitor. The present invention can simultaneously test a plurality of power monitors, and if a certain station is not equipped with a power monitor, it will not affect the normal tests of other stations.

Description

technical field [0001] The invention relates to the technical field of power monitors, in particular to a system and method for mass production and testing of power monitors. Background technique [0002] During the production of the power monitor, due to the layout of its internal components, material selection, plug-in connection, machine or manual welding technology and other issues, it will more or less affect the pass rate of the production product and reduce the product quality of the power monitor. Quality: Bad power monitors, in actual use, directly affect the abnormality of the monitored data, and even cause quality or personal hazards. Therefore, before the power monitor is assembled and ready to be shipped, it is necessary to conduct a comprehensive functional test of the system to ensure that each module of the product can operate normally and stably. [0003] At present, many manufacturers of power monitors will allocate multiple stations, and each station will...

AI Technical Summary

Problems solved by technology

Because in the power system, it is required that the current cannot be broken and the voltage cannot be short-circuited, otherwise it will easily cause a safety accident.

This will lead to the fact that if you only want to test a small amount, such as a power monitor, you must install power monitors on other stations, or connect the current terminals of other stations in series to avoid current disconnection. The manufacturer's power monitor detection device cannot solve the simultaneous test of any number of power monitors
