An approach of intelligent sensor based on CAN bus with PIC16F877A
stand-alone CAN bus controller MCP2501 and PCA82C250 is introdued.The principle of software and hardware for an electronic throttle body CAN bus controlling system which makes all intelligent nodes share data and coorperate each other with high efficiency through intelligent sensor node and CAN bus is also provided.The experiment result shows that the data collected by intelligent sensor is accurate
the efficiency of data transmission is high
the reacting time of the system is fast and the goal of controlling system is reached.
