| Abstract: | At present, automatic monitoring system of pumping station is mainly based on RS-485 bus, which works as semiduplex, pull mode so unable to meet the need of reliability and cost. In this paper, a new automatic monitoring system based CAN bus is presented to overcome much disadvantages of RS-485, including the detailed hardware design and software development. In this system, CPU of intelligent monitor node is a kind of ARM processor, HMS30C7202, produced by Hynix, which embedded CAN controller is 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, high agility. |
