摘要
CAN(Controller Area Net)总线技术,是主要用于各种过程检测和控制的一种现场总线。CAN总线采用双线串行通讯方式,具有很强的检错和抗干扰能力,最高通讯速率可达1Mbit/s,最大通讯距离为10000m。CAN具有优先权和仲裁功能,多个具有CAN总线控制器的带有CPU的仪器连接到CAN总线上,可以形成多主机的局部控制网。本文主要介绍CAN总线技术在导弹遥测系统中的应用展望。
CAN (Controller Area Net)-bus is a kind of field bus mainly used for checking and controlling various procedures. CAN-Bus adopts two-line serial communication mode and owns strong error checking and antijamming capability. The maximum speed rate can reach 1Mbit/s and maximum communication distance is 10000m. CAN possesses priority and arbitration function. Multiple instruments with CPU and CAN-bus controller connected to CAN-bus can form multi-host local control net. The article introduces the application of CAN-bus technique in missile telemetry system in future.
