| Abstract: | A new automatic monitoring system based CAN bus is presented in this paper to solve the disadvantage of ordinary automatic monitoring systems of pumping station in China, which work based on RS-485 bus as Semiduplex. The disadvantages include the detailed hardware design and software development. In this system, CPU of intelligent monitor node is HMS30C7202 ARM processor, which is produced by Hynix and has embedded CAN controller used to communication between intelligent monitor node and industrial computer or among nodes. This system has such advantages as high efficiency, strong interference rejection, high reliability and high agility. |
