Design And Implementation Of A Temperature Inspection Robot Based On Raspberry Pi

The country is undergoing a reform of the power system,and as the core of the power grid,ensuring the safe operation of substations is a very important task.The daily inspection work of substations tends to be automated and intelligent,and the progress and innovation of robot technology have made it an important assistance tool in the field of substation inspection.The function of inspection robots is to monitor the operation of equipment,achieve autonomous navigation,and upload inspection data to the management center,solving the problems of low efficiency,high labor intensity,and difficulty in data query caused by non-standard records in manual inspection methods.This article proposes a substation temperature inspection robot based on Raspberry Pi to address the issues in the traditional inspection process mentioned above.It proposes a method of using QR code labels to achieve device autonomous positioning,temperature measurement,and data storage to improve data accuracy and completeness.The specific research content of the project includes the following aspects:Firstly,by summarizing the current development status of inspection robots at home and abroad,the overall design scheme of the robot designed in this article is proposed,and each part is briefly explained,introducing the key technical functions of the robot.Secondly,conduct technical analysis on the hardware part of the robot,design mechanical structures,select hardware types for each part,and introduce technical indicators.The main control chip of the system adopts the ARM based microcomputer motherboard Raspberry Pi 4B.In the component design,the camera module,temperature sensor,motor drive module,servo drive module,ultrasonic sensor,and infrared sensor are respectively connected to Raspberry Pi to build an experimental platform.Once again,introduce the software part of the robot,explain the software system structure and technical implementation methods,use Python to complete the programming of the robot’s low-level control and intelligent obstacle avoidance functions,and use HTML language to write the user interface.The system combines OpenCV image processing library and Pyzbar algorithm to achieve functions such as positioning,temperature measurement,and data input of substation equipment.Then,functional experiments were conducted on the inspection robot,including remote control function testing,intelligent obstacle avoidance testing,video feedback testing,positioning temperature measurement and data storage testing,and analysis was conducted to verify the feasibility and stability of each part’s operation.Finally,map modeling of the actual working environment of the robot in the substation,designing path planning algorithms for two working scenarios,making relevant improvements,and conducting simulation tests to verify the feasibility of the algorithms.The robot in this article has been tested and achieved the expected effect,which can reduce the labor intensity of substation workers.The improved path planning algorithm shortens the inspection path,making work more efficient and convenient.
