The design adopts S3C6410 microprocessor which is based on ARM11 architecture as its main controller and embedded operating system (OS) WinCE60. Data acquisition module was composed of the wind speed sensor, wind direction sensor, temperature and humidity sensor and air pressure transmitter, and ZigBee technology was used to construct wireless sensor network so as to realize the frontend data acquisition. Embedded SQLite database was used to realize local storage of acquisiton data, and the Advanced Encryption Standard (AES) protocol was used to encrypt data. General Packet Radio Service (GPRS) wireless transmission technology was used to encrypt data, which were transmitted to the remote data service center, in order to carry on the realtime monitoring of the wind field data easily. VS2005 software was used to design its data center software, and the data acquisition system had low cost. Unattended data acquisition was realized, as well as of realtime display and storage. After the module test and overall test, it proves that the system can meet the requirements with quite great popularization value.
