微型电脑应用

针对汽车行驶过程中安全性无法得到保证的问题，提出一种基于CAN总线的车载网络通信系统设计方案。CAN总线具有设计简单、开发成本较低、通信安全性较高等优势，将其应用于系统的开发建设中，可将车载网络通信系统的开发成本降低。将该设计方案分为上位机和下位机两部分，上位机具有辅助功能，可协助测试人员对下位机进行控制与测试，利用仿真测试对系统的安全性及有效性进行验证，测试结果表明，该系统符合预期值。

The car safety cannot be guaranteed in the process, hence, we put forward a kind of on-board network communication system design scheme based on CAN bus and CAN bus. It is simple design, low cost of development, the advantages of high communication security. When it is applied to the development of the system construction, the development costs of an on-board network communication system can be decreased. The design scheme is divided into two parts: upper computer and lower computer. The upper computer has auxiliary functions, which can assist testers to control and test the lower computer. The security and effectiveness of the system are verified by simulation test.
