多功能数显表
本毕业设计的设计任务为一个多功能数显表。该数显表可以测量和显示气压、冲击频率和耗气量。并且具有RS232接口和时间显示。本毕业设计作品选用AK-4气压传感器和LWGY涡轮流量传感器，通过MCS-51单片机来控制操作，实现信号数据的采集、处理和发送。本毕业设计作品不仅可以将气压、冲击频率、耗气量及时间等数据显示在8个LED数码管上，还会通过RS232串口，将数据发送到PC上。并由PC上的配套程序，将信息数据显示在显示器上，这两部分所显示的数据是完全相同的。其中数字显示时间单位为秒，冲击频率的单位为BMP，耗气量的单位为立方米/小时。同时，系统会自动计时，开始运行3分钟之后，自动结束测量、显示，并保存信息数据。-Multi-function digital meter
The design of this graduation project is a multi-task digital form. The digital meter can measure and display pressure, impact frequency and air consumption. And has a RS232 interface and time display. The selection of graduate design works of AK-4 LWGY turbine flow sensors and pressure sensors, through the MCS-51 microcontroller to control the operation, and signal data collection, processing and transmission. This can not only graduated from design work to pressure, impact frequency, air consumption and time data is displayed in 8 LED digital tube, but also through the RS232 serial port, send data to the PC. By supporting programs on the PC, the information data displayed on the monitor, the data shown in these two parts are identical. One time, in seconds digital display, the impact frequency of the units BMP, air consumption of the units of cubic meters/hour. Meanwhile, the system will automatically time to start running after 3 minutes, automatically
