In order to improve the performance of temperature measuring and controlling system, the embedded technology is adopted. The distributed temperature measuring and controlling modules and upper computer are connected as a whole by CAN bus. It not only has the temperature measuring function of individual module, but also can realize centralize control. The temperature measuring and controlling module take Cortex-M3 series LPC1752 chip as the core. Through multi-temperature sensors, collects and processes temperature data of multi- computer rooms. The hardware design and software realization method of lower computer in this system are introduced in details.
