Abstract
A set of intelligent monitor and control system based on CAN bus takes STC89LE54RD+ as microcontroller,SJA1000 as CAN controller and PCA82C250 as CAN controller interface chip.Its software adopts modularization design.The system includes upper program module,data acquisition processing module and CAN communication module,which adopts IBM-PC tolerance PC,singlechip and SJA1000 to compose the two-level control system.Therefore,the integration operating is realized.
