摘要
针对飞行器内系统高速运行与地面测试系统低速运行的特点,为实现飞行器和地面之间稳定实时通信,设计一种CAN总线隔离器,可实现飞行器和地面之间的速度隔离。为更符合该系统要求特点,采用结构化方法独立设计飞行器和地面双方的通信协议。在实际应用中,该CAN总线隔离器设计可行,而且实时通信稳定。
In view of the characteristics of the system high-speed aircraft and low-speed running ground test system, for re- alizing stable real-time communication between the aircraft and the ground, a CAN-bus isolation is designed.The CAN-bus isolation realizes the speed isolation between aircraft and ground.To conform to this system request and characteristic, this system design uses the structurized method to design on the aircraft and the ground both sides communication protocol in- dependently. In the actual application, the CAN-bus isolation is feasible, and the real-time communication is stable.
