摘要
针对目前半挂车存在因超载造成轮胎压力过大,易磨损脱层甚至爆胎等问题,提出在传统TPMS方案上进行改进,采用CAN总线结构实现各轮胎结点与其它汽车电子单元一起构建CAN网络,实现安全预警检测。新系统可扩展性好,通信快捷可靠,是半挂车安全预警装置的发展方向。文中给出了系统设计方案和中央预警模块的软硬件具体实施办法。
An improved scheme suggests CAN network based on conventional TPMS, which is constituted with CAN bus structure and automobiles' electronic cells, aiming to solve the problems occurring in current semi-trailers of tyres extra-pressure, abrasion and even burst caused by overload. So the safe alarm and detection can be implemented. The new system features good expansion, quick and reliable communication. Therefore, it is the developing trend for setting semi-trailers to alarm and detect safety. The design scheme and the practical implementation approaches of central alarming module is described and illustrated in this paper.
