Design of general data acquisition equipment software system based on filed-bus

A software design of multi-channel data acquisition system based on CAN bus is presented. The software design idea, the programmer flow chart of modules and the debugging result are given. The system achieves acquisition for front-end analog and periodic signal frequency through A/D equipment and single chip micro-processor. It accomplishes processing and other control functions by the single chip micro-processor. LCD is used to display and visualize the operation interface. Enactment of measurement range is carried out and the system accomplishes data transfers by CAN bus which achieves its open-architecture and network turns.
