在2019年的12月份，在我国的武汉出现了一种未知的病毒，后被命名为新型冠状病毒。此病毒在全世界范围内迅速蔓延，公共场所的体温检测、人数控制及其口罩佩戴检测是我们日常生活中防疫的第一道战线，也是至关重要的筛查措施。当前针对商场等人流量较大场合下，传统方式都是安排相关人员实时站岗检测，因此会浪费大量的人力和物力，且不能对人数进行及时控制。此次设计为了解决该问题，本设计以STC12C5A60S2单片机为核心设计系统。主要功能是在当前疫情形势下，实现较为安全的非接触式测温、人数控制、口罩识别等功能，从而减少接触系数，降低感染风险。该系统包括单片机最小系统，红外非接触传感器MLX90614，红外计数管、红外避障管、口罩识别、按键电路、LCD1602显示屏、语音播报模块、GSM模块。相比传统温度计，有效提升了防疫工作效率，减轻了医护人员工作负担，非常适合当下严重的抗疫形势。
Abstract
In December 2019, an unknown virus emerged in Wuhan, China, which was later named the novel coronavirus. the virus has spread rapidly around the world. Temperature detection, population control and mask wearing detection in public places are the first front of epidemic prevention in our daily life, and are also crucial screening measures. At present, special people are basically arranged to stand guard and detect in real time under the majority of occasions such as shopping malls, which will waste a lot of manpower and material resources, and the number of people cannot be controlled in time. In order to solve this problem, the design of STC12C5A60S2 microcontroller as the core design system. The main function is to achieve relatively safe non-contact temperature measurement, number control, mask identification, reduce the contact coefficient and reduce the risk of infection in the case of epidemic. The system includes microcontroller minimum system, infrared non-contact sensor MLX90614, infrared counter tube, infrared obstacle avoidance tube, mask recognition, key circuit, LCD1602 display screen, voice broadcast module, GSM module. Compared with the traditional thermometer, it effectively improves the efficiency of epidemic prevention and reduces the workload of medical staff, which is very suitable for the current serious epidemic situation.
