Abstract： Aiming at improving information intelligent control from the image and video of the remote monitoring system in electromechanical products，the ARM core controller based on PLC was added as the controller's control system，a low cost embedded B/S mode of remote real time monitoring system scheme of electromechanical products was designed and implemented. The system utilized Video4linux to obtain electromechanical products' real time working image data by control USB camera，and realized image compression by PNG algorithm，completed the communication between ARM and PLC through the RS232 interface，from which can obtain the electromechanical products' real-time working parameters and transmit the control orders. The system was realized through the embedded Boa server and using B/S mode，CGI technology was used to realize the image and data remote real-time transmission with dynamic. The results indicate that the “ARM+PLC+Web” interaction of this combination of embedded system，to solve the problem that current mechanical and electrical products remote monitoring can not meet the image and video information intelligent processing needs， provides a good platform.
