吸油烟机风量风压测试系统的设计和开发的全部过程。 实现串口通讯技术和使用Excel 2000调出报表的方法是本系统开发的关键之处。作者在本文中重点论述了其具体的设计和实现方法，通过串口通讯来实现数据采集，进而实现对吸油烟机风量风压的检验，并按标准要求打印测试报告、绘制出风压风量和效率曲线。-Range Hood air volume air-testing system in the design and development of the whole process. Serial communication technology and the use of Excel 2000 statements for the transfer of the system is the key to it. In this paper focuses on the specific design and implementation, through serial communications to data collection, so as to realize the right amount of wind Range Hood Pressure testing, in accordance with standard print test reports and draw air-air volume and efficiency curve.

模拟交通信号灯控制，一般情况下正常显示，有急救车到达时，两个方向交通 信号灯全红，以便让急救车通过。设急救车通过路口时间为10 秒，急救车通过后，交通恢 复正常，用单次脉冲申请外部中断，表示有急救车通过。-simulated traffic signal control, under normal circumstances normal show that emergency vehicles arrived, the two directions of traffic lights all red, in order to allow emergency vehicles through. Based emergency vehicles through the intersection for 10 seconds, after the passage of emergency vehicles, traffic returned to normal, with a single pulse for external interrupts, saying that a first aid trucks.
