摘要
CAN(ControllerAreaNetwork)是近年来发展很快的一种现场总线,20世纪80年代初,德国BOSCH公司就提出了用CAN控制器局域网络来解决汽车内部复杂的硬信号接线。目前,其应用范围不再局限于汽车工业,而向过程控制、纺织机械、家用机械、智能机器人、数控机床、医疗器械及传感器等领域发展。CAN总线以其独特的设计,低成本、高可靠性、实时性、抗干扰能力强等特点得到了广泛的应用。本文利用带CAN控制器的高性能8位单片机AT89S52,研制了能同时接受8路不同测温元件输入的带现场总线接口的新型智能测温仪。
The CAN (the Controller Area Network) is a kind of field bus that developed very quickly in recent years. At the beginning of 1980s in 20 century, the BOSCH company of German put forward to solve the complicated semaphore of the automobile inner parts with the CAN controller local area network. Currently it isn't limited to apply in the automative industry, turning to the fields such as tool machine, the medical apparatus and toward to the process control, the spinning machine, household-use machine, intelligent robot, etc. The CAN bus is widely used with its special design, the low cost and high reliability, real-time, the high anti jamming capability, etc. This text makes use of AT89S52 to study the new type measurable temperature meter.
