2020 Electronic Competition Question F-Simple non-contact temperature measurement and identification device (Anhui Division)

This device uses STM32F103 microcontroller as the main control module, and is designed to include an infrared temperature measurement module, an ultrasonic ranging module, an image acquisition module, an identity recognition module, a voice module, a liquid crystal display module and a power supply module for simple non-contact temperature measurement and identification. device. The infrared temperature measurement module is used to achieve non-contact real-time temperature measurement. The temperature measurement range is between 28°C and 48°C. It also has a temperature over-standard alarm function and the alarm temperature threshold can be set within the range of 30°C to 46°C. The voice module can issue alarm prompts. The image acquisition is connected to the STM32F103 microcontroller via USB. The camera records facial information into the picture library for identity comparison and recognition. The identification device can also determine whether the person being tested wears a mask in accordance with epidemic prevention requirements and displays whether he or she is wearing a mask through the liquid crystal display module. This set of simple body temperature measurement and identity recognition devices is simple to operate, has reliable performance, and its technical indicators meet the design requirements and has good human-computer interaction performance.
