Abstract:For the traditional non-contact temperature measurement system with a single function, which cannot realize the functions of GPS positioning and time display, this design proposes a design scheme with diversified functions. The scheme uses IAP15 microcontroller as the controller, combined with infrared temperature sensor, GPS module, memory circuit, keypad circuit, OLED display circuit and other hardware to build a combined infrared temperature measurement and GPS positioning system. Through the analysis of device selection, software and hardware design and debugging, the design is completed. The system has the functions of infrared measurement of human body temperature, GPS positioning information and time display; with the function of ambient temperature measurement; with the function of human body temperature threshold setting and over limit alarm; with the function of location information storage; with the function of Bluetooth transmission. The experiment proves that the system has the advantages of diversified functions, high measurement accuracy, intuitive display and stable operation. Combining non-contact temperature measurement and positioning, the system is a useful reference for real-time monitoring of human body temperature in different environments and locating and storing measurement locations. |
