| Abstract: | To solve the problem that the communication and networking capacity is limited,this paper presents a design of a high precision positioning system based on Ethernet,with FPGA as the core processor,which combineswith a high performance 18 bit digital-to-analog and a 16 bit analog-to-digital conversion module,and a W5300 network communication module and the PID control algorithm.Many sets of positioning control system can be organized into a network through a switch or hub with network transmission speed of up to 50 MBPS,and this network can realize remote setting of position control parameters and acquisition and analysis of real-time position data in the long distance by the the center computer.This system is ecnomical in price and convenient and flexible in operation,so it is suitable for complex distributed control system.It has passed the test. |
