CAN总线智能采集卡的设计与实现

The design and implementation of Intelligent Data-Acquisition Card based on CANBUS

本智能采集卡取代了传统的模拟传感器的功能,将采集到的温度数据进行处理后通过CAN总线传送到主机和其他控制节点,也可以称之为智能传感器。本采集卡是以温箱为采集对象,卡上具有CAN通信接口,并且可以通过CAN智能识配卡与上位机PC进行通信,PC机又可通过TCP/IP协议连入Internet,进而实现远程控制。

In this thesis the design and implementation of Intelligent Data-Acquisition Card based on CANBUS are discussed.This intelligent gathering card has substituted for the traditional simulation sensor function, after will gather the temperature data will carry on processing to transmit through the CANBUS to the main engine and other control node, also might call it the intelligent sensor. This gathering card is take the thermostat as the gathering object,in the card has the CAN correspondence connection,and may match the card through the CAN intelligence knowledge to canT on the correspondence with super monitoring machine,super monitoring machine may pass TCP/IP agreement enters Internet, then realization long-distance control.
