Detailed description of the invention
Digital air pressure and temp moisture measurement monitor is powered and is inputted as power supply by connector Power, its supply district.
For 5-24V; first input power carries out low-and high-frequency filtering through sized capacitors CIN1, CIN2 and CIN3; thus obtain high-quality power supply; it is then passed through the stable+5V power supply of DC/DC module output; three end power supply chip ASM1117 make+5V be transformed into+3.3V and supply electricity to sensor assembly, control processor module, communication module and startup module work; the power supply of LED and current-limiting resistance R9 display system is the most normal; DC/DC module and three end power modules are all integrated with overcurrent protection, thus system protection is the most reliable.Connector CONMS connects the I/O port controlling processor PA2-PA5 for pressure transducer, and PA2 output SCLK provide serial data clock signal；PA3 with DIN is connected offer serial date transfer function；PA4 with DOUT is connected as serial data output port；PA5 with MCLK is connected and is supplied to working sensor clock frequency, and in the design, pressure transducer operating frequency is 32.768KHz.Connector CONSHT connects the I/O port controlling processor PA6-PA7 for humidity temperature pickup, PA6 with SCK is connected offer working sensor frequency and data transmission frequencies, and in the design, humidity temperature pickup operating frequency is 100KHz;PA7 with DATA is connected as the transmission of temperature humidity data.After system electrification work, control processor generation and drive signal accordingly, sensor is under the driving driving signal, start to sample ambient parameter and by the data that obtain by corresponding format with in speed rates to control processor respective cache, control processor and connect lower caching data acquired, decoded data press pressure temperature humidity order format coding, then directly transmit transmission by RS232, it is not necessary to interactive instruction.FPDP can be directly connected to LED screen and show, also can carry out data storage by host computer carries out secondary development simultaneously.
