A REAL-TIME REMOTE CONTROL AND MONITORING SYSTEM USING ZYNQ SOC FPGA BASED WEB SERVER

For the economic development and progress of any country, roads play an important role by providing transportation ease for goods as well as for passengers. The number of vehicles on road is increasing day by day which are controlled by the traditional Traffic Light Controller in the countries like India and other developing countries. In traditional Traffic Light Control system, fixed time is allotted for traffic on each road to pass irrespective of the traffic density. This is an inefficient controlling method which consumes time, effort and fuel of users unnecessarily. But while coming for control system implementation, they consist of parallel operations and conditional executions which cannot be effectively performed on present day FPGAs. This problem is addressed by using Real-Time Traffic Light Control system on Zynq Soc FPGA. This new generation of reconfigurable FPGA has experienced a rapid development in a present day environment which was accompanied by an increased need to monitor, maintain and update of the system. On the other hand, Web technology has become widely used with an ascending trend to migrate everything online and to remotely control systems. This paper describes an approach for the development of a real-time remote control and monitoring system using an FPGA based web server implemented on a Zynq SoC FPGA, which involves Client-Server architecture that act as operating system. The open source Light weight IP (LwIP) standalone TCP/IP protocol stack is used to implement networking capability and the FPGA based web server enables to access the control system by using a web browser to send the information and updates the system.
