摘要
针对现有TPMS的不足,设计了胎压无线监测自控系统(TMACS);介绍了系统的整体设计方案,利用32位ARM微处理器和ZigBee芯片搭建了系统硬件平台,引入了嵌入式实时操作系统μC/OS-II进行软件设计,同时对远端轮胎模块的低功耗要求采用双向通信的设计方法;该系统具有实时监测显示轮胎的压力和温度,异常自动报警等传统功能,并新增了对压力异常的轮胎进行自动调压和参数设置功能,更有效地保障了行车安全。
In order to overcome the shortcoming of the current TPMS, designed tire pressure wireless monitoring auto control system （TMACS）. Introduced its overall plan, by using 32 bits microprocessor and ZigBee achieved its hardware platform. Embedded real-time operating system μC/OS-Ⅱ was added to design software. Bidirectional communication method was adopted to solve the low-power requirements of the remote module. This system not only has traditional function such as real-time monitoring and displaying tire pressure and temperature, auto-alarm for the abnormal tire pressure, but also can auto-adjust the abnormal tire pressure and set parameters. These ensure road safety more effectively.
