Development Of Weather Data Acquisition System Based On MSC1210

Weather data acquisition system is refers can automatically collect, processing, the memory or the transmission meteorology information process. Generally by the sensor, the data acquisition, PC machine and so on is composed. The data acquisition the parameter which gathers to the sensor carries on processing according to the hypothesis request, after the processing meteorological data gives the PC machine with wire or the wireless way transmission.This article introduced the weather data acquisition system is composed by the hardware and the software two parts. The hardware partially uses TI Corporation MSC1210 mcu chip will be the core component, has designed one kind of multi-channel data acquisition that realization in nobody supervising and managing situation to the meteorological element temperature, the humidity, the pressure, the rainfall, the wind direction and wind speed gathering, wireless corresponds the data which two ways will gather real-time through the serial communication and GPRS to transmit on the position computer.Software partially including data acquisition application software and PC application software development. Data acquisition software carries on the sampling, processing according to the hypothesis sampling period to the input sensor signal; On position machine data acquisition software completes with data acquisition correspondence, memory, curve and tabular display. This data acquisition system has the precision high, the volume is small, the power loss low characteristic, can satisfy the meteorological observation the request, also may apply in domain and so on environment, transportation.
