Design of Vehicle Remote Control System Based on 3G Network and CAN Bus[JZ)][HS)]

摘要:

针对传统汽车远程控制系统时延高、安全性差等问题,提出了新的远程控制方案,实现了远程服务器通过车载控制终端对车载网络中各节点设备的远程控制；在远程服务器与车载控制终端通信过程中采用3G网络、TCP协议和AES加密,降低了系统的通信时延,提高了系统的可靠性和安全性；车载控制终端与各节点设备采用CAN总线网络进行通信,实现了对各节点的有效控制；经过测试,系统能很好地满足远程服务器对车门窗、车灯、报警器和发动机等节点设备远程控制时延和安全性的要求,各节点响应快,可靠性高,具有较强的实时性和良好的扩展性。

Abstract:

For the drawbacks of traditional vehicle remote control systems,such as high latency and poor security,a new design scheme of remote control is proposed,realizing that remote server via vehicle control terminal controls each node device of vehicle network. The communication between remote server and control terminal uses 3G network,TCP protocol and AES encryption,reducing the latency of communication,improving the security and reliability of system. Control terminal communicates with each node via CAN bus,realizing effective control of each node. The test results indicate the system meets the need of latency and security when remote server controls vehicle doors,windows,alarms and engine node,each node response fast,with high reliability,strong real-time performance and good scalability.
