WANG Hong-lei1,LI Chuan-fa2,MU Dong-zhou1,ZHANG Xue-song1(1.Xuzhou College of Industrial Technology,Jiangsu Xuzhou 221006,China;2.Xuzhou Medium Mines Alliance & Sci-Tech Co.Ltd,Jiangsu Xuzhou 221000,China)  
This article deals with a kind of interface design,which can control the multichannel CAN bus through the P87C591,the inside CAN controller and the SJA1000.Experiments have found solution for the problem of multichannel communication,i.e,sending and receiving the CAN message at the same time.The paper also analyses and solve the problem of the CAN message overflow,and illustrates the data flow chart and a partial C language source code,thus providing a certain practical value for making a study of the multichannel CAN bus.
