GSM和基于GPS的车辆安全系统。目前几乎有一个自己的车辆公众，盗窃发生在停车场，有时驾驶不安全的地方。车辆的安全是公共车辆非常必要的。车辆跟踪和锁定系统安装在车辆中，以跟踪位置和锁定发动机马达。使用全球定位系统（GPS）和全球系统移动通信（GSM）的所确定的车辆的位置。这些系统要不断地观察一个移动的车辆和报告需求的状态。当防盗识别，相关负责人发送短信给单片机，单片机再发出控制信号，以停止发动机马达。授权人需要发送密码到控制器重新启动车辆并打开车门。这是更安全的，可靠的和低cost.VVVVVV

ARM7下面读写串口的两种方式：中断方式和查询方式的源代码。详细介绍了ARM7下面读写串口的方式。-ARM7 serial read and write the following two ways: interrupt mode and query the source code. Described in detail ARM7 serial read and write the following way.

在数字电路的设计中，时序设计是一个系统性能的主要标志，在高层次设计方法中，对时序控制的抽象度也相应提高，因此在设计中较难把握，但在理解RTL电路时序模型的基础上，采用合理的设计方法在设计复杂数字系统是行之有效的，通过许多设计实例证明采用这种方式可以使电路的后仿真通过率大大提高，并且系统的工作频率可以达到一个较高水平-In digital circuit design, timing design is a main indicator of system performance in high-level design methods, control of timing was also a corresponding increase in the abstract, so more difficult to grasp in the design, but in understanding the RTL circuit timing model based on rational design methods used in the design of complex digital systems is a well-established through many design examples prove that this approach can make the circuit after the simulation significantly improve pass rates, and the system operating frequency can reach a high level
