摘要
根据煤矿抽水泵站水池液位连锁问题,设计了一种采用CAN协议总线作为数据传输手段,利用单片机和外围电路构成总线采集传输节点。该系统可以对水池液位高度实时采样、显示和报警,同时各节点采集的水池液位等参数经CAN总线传输实现联动控制系统。
According to the linkage problem of water level at a pump water station in coal mine, a system adopting CAN protocol bus as the mean of data transmission and using both the single chip microcomputer and peripheral circuits as the bus acquisition and transmission nodes is designed. The system can do real-time sampling, displaying and alarming for water level, at the same time, the parameters such as water level that acquired by all nodes can be transmitted through CAN bus to realize a linkage control system.
