基于CMC芯片的信号采集系统设计

The Design of Signal Sampling System Based on CMC Chip

基于高性能低功耗的工业控制芯片,研发新型信号采集控制系统,涵盖开关量输入、输出:模拟量输入、输出:内置PID模块和标准功能块,支持MODBUS/CMC通信协议,提供两种通信总线的接口、自由量程设定、超量程警报等功能,开发的信号采集系统稳定性好,适用各种工业场合的监控。

This study proposes a new Signal Sampling System, which is based on Industrial Control Chip that is high performance and low power consumption, covering the functions like switch signal I/O, AI/AO, inner PID, measurement range set, outrange alarm, besides this new Signal Sampling System supports communication protocol of MODBUS /CMC and provides two kind of communication bus interface. The results show that this new developed Signal Sampling System has high system stability, can be applied to monitoring application of various industrial situations.
