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
