Abstract:Abstract:It introduces a infrared measuring temperature system which makes ARM as its processor, in the system, it design and transplant real time operationg system uC/OS-Ⅱ, it can complete the detection of the disk surface temperature , and it displayed the object surface of each area of temperature and its distribution curve on LED,the specified points can be pointed through touch screen. Meanwhile, the system used an open-source TCP/IP protocol, it can realize the connection and interactive information between the system and external PC devices. The design has a certain reference value for the surface temperature of infrared detection
