Abstract:A sort of design technique of distributed measurement and control system is given. The overall framework of system was expounded. Design scheme of universal measurement and control terminal was introduced mainly. Key techniques were analyzed in many modules design. This system was based on Field-Programmable Gate Array (FPGA) and ARM dual-core control. Analog input and output, conditioning circuit, switch input and output circuit, pulse input and output, Controller Area Network (CAN) communication interface, FLASH read and write modules were devised. Experiments show that this system has advantages of openness, miniaturization, network interconnection, friendly man-machine interface, high reliability, and high cost performance characteristics.
