Device and method for automatically detecting intelligent ammeter liquid crystal wheel display content

Abstract

The invention provides a device and method for automatically detecting intelligent ammeter liquid crystal wheel display content. The device comprises an industrial personal computer, a serial server for carrying out RS 485 communication with an ammeter, an ammeter bearing tray for loading the ammeter, an image collecting unit for collecting images of a display screen of the ammeter, a driving device for driving the image collecting unit to move, an image processing unit for processing the collected images, a powering-up unit for enabling the ammeter to be in the working state, a PLC relay and a wiring mechanism. The image processing unit receives site collected signals of the image collecting unit to process the images, the image collecting unit and the driving device are respectively connected with the industrial personal computer, the industrial personal computer is connected with the serial server through communication, and the serial server is communicated with the ammeter through an RS 485 bus. The device can automatically finish intelligent ammeter liquid crystal displaying detecting and intelligent ammeter running state displaying polling.

Description

technical field [0001] The invention relates to the technical field of electrical measurement and electrical energy measurement, in particular to a device and method for automatically detecting the content displayed on a liquid crystal wheel of an intelligent electrical energy meter. Background technique [0002] The appearance automatic inspection unit is a main execution unit in the automatic verification assembly line of the smart energy meter. It is generally composed of the automatic transmission line of the smart energy meter, automatic wiring, automatic power-on module, automatic camera and intelligent image processing unit. The image recognition module passes Trigger the LCD backlight and full-screen display of the smart energy meter, automatically complete the shooting of the appearance, nameplate logo, LCD full-screen display and indicator lights of the smart energy meter, and realize the automatic detection of panel and display defects through the intelligent image...

Problems solved by technology

However, such a traditional method is to use a smart camera to take photos of the full display content of the smart energy meter when it is powered on to detect whether there is a gap in the display screen when the power is turned on, and it is impossible to detect the specific display content of various split-screen wheel displays. , if you need to detect the content displayed on the split screen, you need to press the display switching button of the smart energy meter to switch the content displayed on the screen, and then take a photo to determine, which results in low detection efficiency and insufficient simplification of the detection method
