Research On The Design Of Laboratory Environment Safety Inspection Robot And Its Control System

With the development of robot intelligence technology,inspection robots are gradually being used in more and more fields.In addition,in recent years,the country has paid more and more attention to the environmental safety of university laboratories and scientific research institutes.Inspection robots will provide laboratory safety control a means and tool.Although many research institutes and enterprises have researched and designed many different types of inspection robots,these machines are mainly used in fields such as high-voltage transmission lines and urban integrated pipe corridors.There are few researches on inspection robots for laboratory environment safety.Taking the laboratory environment safety as the starting point,this paper conducts in-depth development and research on the mechanical structure,hardware system,control and management system of the inspection robot.First,after analyzing the development status of inspection robots at home and abroad and the requirements of laboratory environment safety inspections,the design requirements of inspection robots are clarified.Comparative analysis of the advantages and disadvantages of different structural forms of inspection robots,determined the structure design of the whole machine,and carried out a detailed design of its structure.It is divided into three main modules:walking mechanism,lifting mechanism and detection platform.According to the functional requirements of each module,a specific design plan is given,and the feasibility and reliability of the mechanical structure design are verified through parameter calculation and simulation.At the same time,some necessary auxiliary devices are designed to ensure that the whole machine can work normally.Secondly,according to the inspection robot motion control requirements,the inspection robot control plan with Xinjie PLC as the main controller was determined,and the required control system hardware was selected to complete the hardware control system construction.The entire control is divided into three parts:manual and automatic control,motor speed regulation and speed measurement,and data acquisition.The linkage design with the host computer system is carried out to complete the design of the entire hardware control program of the inspection robot.Thirdly,the functional requirements of the remote control management system are analyzed,VB6.0 is selected as the development language,the hardware control program is coordinated,and a set of matching upper computer control management software is developed.The entire control management system mainly includes four modules:motion control,data display,video monitoring and database.According to the design principles of human-computer interaction interface,the interface design of the control system is given.Finally,through the prototype production and the establishment of a test environment,the necessary functions such as walking stability,lifting stability,positioning accuracy,sensor collection data accuracy,upper computer communication reliability and wireless charging of the prototype were tested,and the test verified the designed inspection The robot has a certain practicability and lays a good foundation for the improvement and upgrading of products in the future.
