Research And Realization Of Embedded Intelligent Control System For High Voltage Switch Detection Line

With the continuous improvement of the industrial technology development in China,electricity as one of the basic protection of industrial social development can be said to be the most important basis.But in the use of rising demand today,faced with two major problems:1.Power equipment safety and stability in the complex environment and the use of the process can not be effectively guaranteed;2.High-voltage switch quality testing means not intelligent and automation.One of the key components of a safe and stable electrical equipment system is a high-performance vacuum switchgear with breaking protection,the core of which is the high voltage switch.Therefore,high-voltage switch must be in the quality of protection,especially in the product testing of the link must ensure that the product quality testing accuracy and accuracy,to minimize the artificial intervention in the detection process to avoid man-made errors and errors The This requires a set of high-quality,high-efficiency automated testing equipment,instead of manually complete all the testing work including product transport,product performance testing,product quality distinctions and other columns may cause human interference.This research is based on the actual project of the intelligent control circuit of the high voltage switch product,and carries on the research and the realization to the transportation line control system,the handling robot and the comprehensive detection control system applied to the detection line.Transportation system to complete the product testing input,output and sorting work;handling robot to complete the high-voltage switch products handling(including loading and unloading material handling two links);integrated test station is completed on the high-voltage switch product performance testing,Including the appearance of detection,internal resistance detection,self-resistance force detection and vacuum detection.The subject needs to complete the hardware and software design and research of the corresponding control system according to the actual functional requirements of the high voltage intelligent control circuit.The transportation line adopts the embedded design,which consists of 16 Freescale microprocessors and various peripheral modules including:chip power circuit,real-time clock circuit,reset circuit,communication circuit,input and output circuit to realize the control system communication,motion control Function.The mobile robot and the integrated detector motion controller are also embedded in the design,32-bit high-performance ARM microprocessor LM3S9B96 and dedicated motion control chip PCL6045 BL combination to achieve,between the two parallel communication.On the basis of hardware,the modular and multitasking software design ideas are used to develop the system software control process in the uC/OS-Ⅱ environment,which occupies the first multi-task real-time embedded operating system kernel,and realizes the motion control unit module,communication module,A/D sampling module and fault handling module and other software development process,and in the underlying software module based on the realization of the transport line,handling robot and integrated test console control system software control process.In the field of operation,intelligent control test line has a very good stability and reliability,to meet the product testing accuracy and detection efficiency requirements.
