Remote Laser Monitoring System Based On CAN Bus

In recent years,the rapid rise of the Internet of Things,the strong potential of the market has been stimulated,and the Internet of Things technology has become a new driving force for economic development.It is an intelligent network that connects controllers,sensors,machines,objects and people through Internet technology to enable information transfer between objects and people,things and things.It has a wide range of applications in smart homes,driverless,smart security,smart energy and environmental protection,industrial monitoring and other fields.This topic selects the "Internet + Laser" mode to collect the operating parameters of the laser through the CAN bus module,and transmit it to the remote server for real-time display via the Internet to realize remote monitoring of the laser.CAN bus is an international standard field bus,which has a wide range of applications in industrial control,automotive manufacturing,medical equipment and other fields.By connecting each control unit on the laser to the CAN network topology,the nodes of the control unit can be flexibly increased or decreased to obtain more abundant laser operation information,improve the reliability and anti-interference ability of data acquisition,and is more conducive to laser failure.Monitoring and troubleshooting.This topic is based on CAN fieldbus and IoT technology to realize remote monitoring of lasers.The main work contents are as follows:(1)In-depth analysis of the monitoring target laser,and research on the laser control method and remote monitoring scheme.On this basis,the overall scheme of laser remote monitoring system based on CAN bus and Internet of Things technology is designed.(2)With the STM32F103 chip as the core,the design of the laser discharge protection and detection CAN module is completed,and the real-time collection and protection of the discharge current of the 6-channel discharge tube can be realized.The STM32F103 development board design program enables real-time acquisition of signals from a variety of other laser parameters such as temperature,power,and discharge tube current.The CAN bus communication program of the lower computer is designed,and the parameters of the laser are transmitted to the upper computer in real time.(3)Customize the CAN bus application layer protocol according to the characteristics of the laser remote monitoring system in the host computer,and complete the communication program design with the lower computer CAN module.The EDP protocol design program is used to connect the host computer equipment to the China Mobile OneNET platform,and the web page is designed on the server side to realize real-time display of laser data,threshold alarm,remote control and other functions.(4)With the help of CAN analyzer,EdpProtoDebugger software and other tools to test the hardware connection and software program.On the one hand to verify whether the CAN bus communication function and performance meet the system requirements,on the other hand to detect system loopholes,timely changes and improvements.
