地面CAN总线隔离器测试台的设计

摘要

This paper introduces a design of ground test-platform for CAN-bus isolator .which performance can be fully measured through the test—platform. As the effect of the CAN-bus isolator,which can ensure stable real-time communication between the high-speed telemetry equipment of missile and the low-speed test-device of ground in aircraft systems,it was to isolate the speed between them,the test platform simulate the communication between them with isolator. This paper design a unified communication-protocol,which respectively simulate the communication between CAN-node of the missile and the ground with the isolator. In practical applications,the design of test-platform for CAN-bus isolator was feasible,which can fully examine the performance of CAN-bus isolator.%该文设计了一种CAN总线隔离器测试台对CAN总线隔离器的性能进行全面测试.由于CAN总线隔离器是对飞行器系统内弹上高速遥测设备和地面低速测试设备之间进行速度隔离,它可以确保飞行器弹上遥测设备和地面测试设备之间稳定实时通信,所以测试台对隔离器进行性能测试时模拟了地面测试设备和弹上遥测设备同隔离器之间的通讯.该文中设计了统一的通信协议分别模拟弹上CAN节点和地面CAN节点同隔离器之间的通讯.在实际应用中,该CAN总线隔离器测试台设计可行,能全面检验CAN总线隔离器的性能.
