Multi-Channel Data Acquisition and CAN Communication System Based on Single-Chip Microcomputer

Abstract

Aimed at the problem that the traditional data acquisition system design with low efficiency and high cost. It is proposed that the C8051F040 microcontroller is based on the integrated A/D converter and CAN controller; utilize dynamic control simulation input quantity into the built-in A/D converter, process and store the data through the micro-processing unit, and use integrated CAN controller to transmit the data. From schematics design to the boards development, we have achieved the functions that acquisition of multi-channel data combined with CAN network communication through hardware and software debugging. The design of this product is small, powerful and wide used. It has good application and development prospects.
