摘　　要：检测体温是预防和控制流感的主要手段,而传统的水银体温计和人体红外测温仪在应用中存在诸多不便。利用STC单片机并行控制DS18B20温度传感器,设计了适合学校使用的快速多点体温检测系统。该系统每分钟可以同时为64位学生检测体温,并将体温数据即时显示到LCD 12864上,方便医护人员记录。实践证明,采用DS18B20的多点体温检测系统具有成本低廉、快速检测、并行支持多用户、使用简便等特点,满足快速检测大量用户体温的需求。Measuring body temperature is the primary means to prevent and control influenza, while the traditional mercury thermometer and infrared thermometer are so inconvenient in operation. By adopting STC single chip computer to control DS18B20 temperature sensors in parallel, the fast speed multiple-point measuring system for body temperature suitable to be used in schools has been designed. With this system, body temperature of 64 students can be measured in every minute, and the data can be displayed on LCD 12864 for easy record of heahheare professionals. The practice verifies that such system features low cost, fast speed measurement, easy operation, and supports multiple users in parallel to meet the demand of fast speed body temperature measurement for a large amount of users.
