| 摘 要： | 本文提出了一种以Intel8031单片机为网络控制器的“总线式复合测试网”。网络采用CSMA／CD通道访问协议，通过软件实现网络的全部通信过程，各数据设备（主控计算机、局部测试系统、测试仪器及辅助外设）相互独立，通过控制器的数据接口单元入网。实验表明，网径为1Km，通信速率可达110kb／s。该网络系统结构简单，成本低廉，在计算机自动测量和控制领域里有推广和实际应用意义。

| Abstract: | A bus-type compound testing network using Intel 8031 monolithic microcomputer as the network controller is presented in this paper.Adopting CSMA / CD access protocol, the network communication is achieved by software. All the data devices (main control computers, local area testing systems, measurement instruments and auxiliary peripheral devices) are independent to each other in communication process and linked to the network by the control1er interface units- The experiments show that the communication rate is up to 110 kb / s when the network length is 1 km. Being simpler in system structure and cheaper in cost, the design is valuable to computer automatic measurement and control. |
