基于SOC多核单片机远程测控模块的研究

Research about the Remote Measurement and Control Module Based on the SOC Microcontroller

通过采用SOC多核单片机简化硬件设计、增加工作速度及通道数,对20mV以上的信号无需用户加装调理电路,可直接服务到端子,能够满足恶劣的工业现场对模拟、开关、脉冲量信号抗干扰性的需求。具有两个以上RS-485通信接口,既可与上位机交换数据又可自行组网。运用SMBUS和MODBUS通信协议实现单片机之间的通讯。

The hardware design can be simplified, and the working speed and the number of channels can be increased by the use of SOC multi-core microcontroller.The signal above 20mV can also work well with- out conditioning circuit.It can directly service to the terminal.The interference immunity of switch,analog, pulse signal conditioning circuit can meet the demand of harsh industrial fieldJt also can exchange data with the host computer and found its own network with more than two RS-485 communication interfaces. The communication between microcomputers is realized by SMBUS and MODBUS.
