Design of Data Collection System Based on CAN Field Bus

A low-cost plan for data collection system was introduced based on characteristics of CAN field bus technique, with overall structure of the system presented. The principle of hardware and method of software designing were explained. It indicates through the test that the system is simple and highly reliable, having improved the integrated degree of control testing system to answer for the data communications between the PC and the test system, which can be broadly used in distributed control system.
