Abstract: With the rapid development of industrial control network, more and more attention is paid to the fieldbus technology. As one of the highest market share in fieldbus, the CAN-bus has been widely used in the field of industrial control and other related fields, due to its openness, high reliability, good real-time performance and lower cost, iCAN system has iCAN protocol in the CAN-bus application layer, which has effectively solved the users’ problem of communication control and data collection and also meets the need of most domestic users of small and medium-sized fieldbus network. Basing on iCAN system, this paper designed and implemented an improved system to monitor and control the pumps at water source places with flexible construction, simple structure, low cost, good reliability and stability.
