摘　　要：为了解决数据从现场传感器传送到控制机房过程中的数据干扰、误码、丢失等问题,设计了一种以Cortex-M3-LPC1788为微控制器的多通道数据采集系统。该系统主要完成机械设备在运行过程中的数据采集、故障诊断及预测,实现了RS-485总线、CAN总线和以太网通信并存的数据通信方式,使得现场应用更为方便、灵活。In order to solve the data interference,error,loss and other issues during the data＇ s being sent from the field sen- sors to the control room, a kind of multi-channel data acquisition system, which use Cortex-M3-LPC1788 as a mierocontroller was designed. And it was mainly designed for data acquisition, fault diagnosis and prediction during operation of the mechanical bear- ing, meanwhile, it aJse realize coexist of data communication method with the RS - 485 bus, CAN bus and Ethernet. This method of data communication makes field applications more convenient and flexible.
