基于CAN总线的车辆液晶显示处理系统

文章介绍了车辆状态信息显示处理系统及cAN总线在现代客车上的应用。该系统是以AT89S52单片机 SJA1000CAN控制节点十SED1335液晶显示控制器为核心，并辅以扩展电路构成的汽车行驶记录仪。在研究、参考国内外现有行车记录仪的基础上，充分利用现代电子、计算机、传感测控等方面的技术成果，开发了新一代基于CAN总线的多功能行车记录仪。该系统不仅具有检测、超限报警等常规功能，而且具有点阵LCD中文显示功能．数据存储功能，以及控制功能。实现了更高的智能水平。

Application of Display and Processing System Based on CAN-bus

The application of display and processing system of vehicle status information based on CAN bus is introduced. The system is based on AT89S52 8-bit microcontroller, SJA1000 CAN controller and SED1335 LCD driver, and accessorized with the vehicle running recorder. Under the study of the existent automobile data recorder, an advanced multi-functional security monitoring system for car is developed, which takes advantage of the technology progress in the fields such as electronic, computer, sensor and controlling. The system not only performs the general functions such as detecting, alarming and so on, but also possesses LCD interface to report parameter and working conditions, and the controlling functions.
