汽车信号灯检测与处理系统硬件整体设计

Hardware design of detection and processing system for automobile signal lamp

本设计基于AT89C51单片机开发汽车信号灯系统故障检测与替代的智能控制软硬件系统。该方案检测汽车信号灯可能出现的故障,进行软件处理。系统正常时,按正常信号灯要求操控;信号灯出现故障时,可视化的警示同时在不影响其他信号灯操控的情况下对故障信号灯进行功能替代,减少和防止可能的交通隐患。该方案可对故障部位进行可视化文字提示,司乘人员能及时准确的发现问题,也为维修人员解决问题提供帮助。汽车信号灯控制系统包括软硬件两部分,硬件主要包括电源、主机、前后控制器、文字显示等,软件用汇编编写,包括信号灯控制、故障扫描、故障提示、故障替代等模块。以下为控制系统硬件整体设计。

The design is based on AT89C51 MCU development automobile signal lamp system fault detection and the replacement of the intelligent control software and hardware system. This scheme can detect the faults of the automobile signal lamp, and carry out the software processing. Normal system, control according to the requirements of the normal signal lights; signal lamp failure, visual warning also in does not affect the other signal lamp control of signal lamp failure function alternative, reduce and prevent possible traffic hazards. The scheme can prompt the fault parts for text visualization, passengers can timely and accurately discover a problem, but also for the maintenance personnel to help solve their problems. Automobile signal lamp control system includes two parts: hardware and software. The hardware includes power, host, and controller, text display, software used to prepare a compilation, including signal lamp control, fault scanning and tips, fault substitution module. The following is the overall design of the hardware control system.
