Power monitoring instrument batch production test system and method

Abstract

The invention discloses a p<{EN0}>power monitoring instrument batch production test system, which comprises a processing terminal, a power source, a measurement and control module, connection modules,a hub, a scanner, detection switches and indicator lights. The power source is connected with power measurement and control instruments through the connection modules; the power measurement and control instruments are communicated with the processing terminal through the hub; the power source and an output module communicate with the processing terminal through a serial port; one end of each detection switch is connected with the common end of the measurement and control module, and the other end of the detection switch is connected to a DI interface of the measurement and control module; theindicator lights are connected to DO interfaces corresponding to the DI interfaces; and the scanner is connected to the processing terminal. The invention also discloses a power monitoring instrumentbatch production test method. The system and method can simultaneously test multiple power monitoring instruments; and if some station has no power monitoring instrument, normal test of other stations is not influenced.

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...

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
