1、 论文题目：论文题目：大型货车制动过热自动控制系统大型货车制动过热自动控制系统 摘摘 要要 大型货车在丘陵地带或坡道上行驶时需频繁或长时间刹车，会造成刹车鼓 （盘） 、制动蹄温度骤升，轮毂温度聚增，在剧烈高温下最终会导致刹车失灵， 以及温度过高至使轮胎气压过高而出现爆胎现象而造成安全事故， 通过对国内外 刹车过热问题采取的解决方法的研究,最好的解决方案是设计出了一套大型货车 制动过热自动控制系统装置,该系统由温度检测单元、液位检测单元、人机接口 单元以及单片机控制单元等部分组成。 该系统通过遥控发射接收装置控制大型货 车制动过热自动控制系统的开启或关闭,有自动和手动两种工作模式;在自动方 式下

2、,DS18B20 温度传感器通过感应当前刹车毂或止动蹄的温度，对刹车系统温 度进行实时监测,温度信号输入到主控芯片(AT89C51 单片机),主控芯片根据设定 的温度条件输出控制信号,启动喷水设备对刹车系统降温;在手动方式下,也可以 控制单片机启动喷水设备，降低刹车系统的温度。本课题对系统的硬件和软件进 行分析说明，通过绘制相关的硬件连接图和软件流程图,建立系统软硬件模型， 证明该系统可以实现对大型货车制动过热自动控制的功能。 关键词关键词:制动系统;DS18B20 温度传感器;电容开关传感器;AT89C51 单片机； 2262,2272 遥控发射接收模块 Design Of The Temp

3、erature Self-control Of The Truck Skid System Abstract Required frequent or prolonged braking when large Vehicles with goods driving on hills or ramps ,it will cause the brake drum (disk) , brake shoe temperature leapt hub ,at the same time, it will increase the truck skid system in the high tempera

4、ture , eventually ,the result will cause severe brake failure, and the high tire pressure temperature is too high to make the phenomenon appear flat tire and caused accidents, according to research the solutions of overheated brakes in abroad, the best way solution is designing a new set of device .

5、the set of device with the temperature self-control of the truck skid system inclusions the temperature detection unit, the level detection unit,the man-machine interface unit and the MCU control unit and other components. The device with the temperature self-control of the truck skid system run on

6、or off by the transmitting and receiving device ,it has automatic mode and manual mode,in the automatic mode, DS18B20 temperature sensor measure real-time monitoring of the truck skid system temperature by sensing the current brake shoe on the wheel or the temperature of the stopper , and send the temperature signal to the master chip (AT89C51 MCU), the main chip export the output control signal according to the main chip set temperature, to start to spraying equipment to cool the braking sys
