Abstract :
The paper introduces a wireless sensor network (WSN) used for an intelligent temperature measurement system. In the system, temperature signals are acquired by digital multipoint thermometers, and transmitted to the advanced RISC microprocessor (ARM) by using Wireless Fidelity (WiFi) technology. Then they are stored in SD card which is controlled by the microprocessor according to the IIS-bus standard format. The software design of data acquisition is completed in this paper. The progress of transplanting Linux operating system to the ARM hardware platform is described, and the driver programs of SD card and SD WiFi device are developed based on Linux operating system and SD card agreement. A special data storage file system is accomplished for reading and writing SD card, as well as managing of the data file by the FAT16 file system. At last, the function of man-machine interaction is accomplished.
