基于CAN-bus的载体销毁触发系统的研究

Research of a storage destruction trigger system based on CAN BUS

针对紧急情况下敏感信息泄漏问题,设计了一种实时触发的信息载体销毁触发系统结构框架及其触发机制;在研究了CAN总线技术的基础上设计了消息类型和适用于信息载体销毁触发系统的CAN总线应用层协议;运用CAN适配卡及其提供的动态链接库实现了一个原型系统;实验结果表明该系统具有高实时性,能实时触发被控设备。

To solve the problem of preventing sensitive data from leaking when an emergency occurs, a framework and trigger mecha- nism of the real-time triggering information storage destruction trigger system are designed. The messages and CAN application proto- col which are suitable for the system are designed after studying CAN bus techniques. A prototype system is implemented by using CAN adapter and its dynamic-link library, The result of the experiment demonstrates that the system has a high capability of real-time, it can trigger the controlled equipments in time.
