Abstract
This paper introduces a kind of distributed test system based on CAN (Contoller Area Network) bus and virtual instrument tech- nique for engineering equipment. It consists of host and intelligent node, with parameter signals communication through CAN bus to form a distributed high-precision status parameters test system. The host computer implements the user interaction, data storage, status monitoring, power measurement and computation as well as management. The client unit reads the commands of host, detects all the parameters of system and transmits the data. The hardware and software structure of the distributed testing system (client) with ATmega128 micro single chip computer and communication module are implemented. And the application software was developed with graphical virtual instrument language LabVIEW.
