摘要
在测控系统中应用CAN总线,充分利用CAN总线的优点,使系统庞大,应用环境复杂的测控系统中分系统之间的信息交换可靠地进行,提高整个测控系统可靠性。提出了3种CAN总线节点实现方法,在比较各种实现方法的基础上,选择了DSP芯片的方法。在某雷达设备改造中,分系统之间的通信采用CAN总线,CAN总线的灵活性、高稳定性、强的抗干扰能力都得到了充分的体现。
The stability of the observation and control is enhanced by adopting CAN bus and fully utilizing its strongpoint in the observation and control system,which makes the information exchange between subsystems（in the observation and control system working in the complex environment） reliable.Three ways to realize CAN bus node are proposed.DSP chip was selected on the basis of comparing three ways.In a radar improvement,CAN bus was applied in the communication between subsystems.The flexibility,high stability and high anti-jamming performance of CAN bus were reflected in the observation and control system.
