On The Research And Realization Of Portable Meteorological Data Collection System

In our daily life, and in the industry and agriculture production process, we need some meteorological informtions such as temperature, humidity and barometric etc. However, the traditional methods, manual measurement and manual reading meter, not only make a waste of time and manpower, but also make some errors. So it is a must to develop a more advanced data collection system so as to collect the meteoralogical informations more conveniently,faster and accurately.In this thesis, a portable meteorological data collection system is proposed and developed. In this system, informations including temperature, humidity, dewpoint, barometric, time, location and so on, are collected by temperature/humidity sensor, barometric sensor and GPS, real-time displaying in LCD, and sent to network center by GPRS. In the network center, the database and website are created and the collected informtions are taking on and managed by the website. Both hardware and software of the data collection terminal have been designed. And the software of the network center has also been designed. The tests to prove the stability and performance of the complete system have also been given. Experimental results show that the system can collect and manage meteorological informtions stabilitily and achieve the expected goal.Meteorological data collection system is designed and based on the advanced technology of MCU, communication, sensor and so on. So the meteorological informations are collected more accurately and efficiently. What's more, it can be operated more conveniently by user for its portable characteristic.
