基于CAN的火控光电仪数据交换网络设计

基于控制器局部网(CAN)的火控光电仪数据交换网络，采用CAN为系统各节点间的数据交换平台，通过CAN协议对通信数据块编码，扩展数据节点，设置节点筛选器，数据节点通过各自CAN控制器与总线相联，实现网络数据交换。其中，系统监控台接收并显示网络中传输的全部数据，其设计包括不同数据节点的CAN控制器，及单片机控制的CAN接口模块和基于DSPTMS320LF2407A的CAN总线接口等。

Design of Data-Changing Network for Firepower-Control Electrophotometer Based on CAN

In the design of data-changing network for firepower-control electrophotometer based on CAN, the controller area network (CAN) is used as the data-changing platform between data nodes of he system, the communicated data is encoded, data nodes are extended and filters of each node in the net are configured via the CAN protocol. Data nodes are connected to the bus through their own CAN controllers to realize network data-changing. All data transmitted in the net can be taken and displayed by the system console node. The design includes designs of different CAN controllers for different data nodes, the CAN module controlled by single chip computer and can bus interface based on DSP TMS320LF2407A, etc.
