Design Of Automatic Verification System For General Electric Instruments

With the increasing demand for the use of automatic instruments,the detection of instrument accuracy is also indispensable.The traditional manual verification to complete the detection of power instruments is inefficient and gradually unable to meet the demand.In view of this practical project background,this paper studies and designs the instrument automation verification technology,and replaces the complex manual operation,which shows that this research has important practical significance for the popularization of automation technology.This project comes from the project of intelligent instrument calibr ation robot development(achievement transformation)-R & D and trial production of intelligent instrument calibration robot of China Southern Power Grid.The purpose of this project is to develop a universal verification platform for electric instruments.Based on the background and significance of the project,this paper investigates the research status of the instrument automation verification technology,and according to the actual needs of the project,finally realizes the development of the power instrument automation verification platform.Aiming at the problems of low automation and slow efficiency of power instrument verification equipment,this paper studies the recognition algorithm of monocular camera,the principle of hand eye calibration of mechanical arm,the use method of electric pneumatic actuator,ado.net and other related technologies,and uses the Internet of things as support,mobile sensing,information sensing,automatic control and other related technologies combined with automatic c ontrol system It has built an automatic,networked and intelligent measurement and calibration system.The power instrument automatic verification platform is composed of mechanical arm control module,instrument positioning module,instrument calibration verification module,digital identification module and data storage management module.Each module is integrated into a distributed network system through network information sensing.In the aspect of hardware,according to the appearance structure of electric instrument and the requirements of verification,the hardware equipment should be reasonably selected,designed and processed,and the precise control of pneumatic actuator and electric actuator should be realized by using the IO quantity in the control cabinet,as well as the operation of dismantling and wiring and adjusting the range of the instrument by using the mechanical arm.In the aspect of software design,using C# language to develop the design part of the main control unit,using the human-computer interaction structure,the system running state can be provided to the user in real time,and the verification results can be saved in the database of the main control unit.Finally,through the joint debugging of each module,through the analysis of the verification experimental results of the instrument,it can be concluded that the design platform is stable in operation,accurate in verification results,and can carry out automatic verification for most of the instruments,which meets the actual needs.
