Abstract and Keywords

Abstract: In order to prevent accidents caused by overheated brake drum temperature or excessively high differential oil temperature under high load after the long-time braking of truck, this paper designs a monitoring and prediction system for truck brake drum temperature and differential oil temperature based on STM32F429 and STM32F103 single chip microcomputers working together. This system uses STM32F429 single chip microcomputer as the main processor, uses controller area network (CAN) bus and slave processor with STM32F103 as the core to carry out timely data transmission and storage, and integrates into STemWin system to design human machine interface. The temperature prediction model is established based on the moving average theory of autoregressive quadrature. The simulation results show that the system is stable, reliable, accurate and can effectively reduce the accidents caused by high brake drum temperature or differential oil temperature.

Keywords: STM32 single chip microcomputer; controller area network(CAN) bus; human machine interface; brake drum temperature; temperature prediction model

摘要和关键词

摘要: 为防止卡车在长时间刹车后,刹车鼓温度过热或高负载情况下差速器油温过高而发生事故,文章设计一种基于STM32F429和STM32F103单片机协同工作的卡车刹车鼓温度、差速器油温监控与预测系统。该系统以STM32F429单片机为主处理器,利用控制器局域网(controller area network, CAN)总线和以STM32F103为核心的从处理器进行及时数据传输和存储,并融入STemWin系统设计人机交互界面,基于自回归求积移动平均理论建立温度预测模型。仿真结果表明:该系统稳定可靠、预测精准,能有效减少因刹车鼓温度或差速器油温过高而引起的事故。
