摘　　要：温度报警器系统以AT89S52单片机为主控制器,对温度报警和时间的显示、调整进行控制。采用高精度DS18B20为温度传感器,实现对环境温度的实时检测与采集,通过12864液晶显示温度和时间,当实时温度高于温度报警上限或低于下限时可利用蜂鸣器进行报警。通过红外遥控可以修改温度报警上限和下限、时间参数以及设置闹钟。本设计的创新点是增加了用VC6.0开发的上位机,在计算机上显示出时钟、温度计和视频界面,构成友好的人机界面。因此,本系统具有很高的实用价值。Temperature alarm system based on AT89S52 single chip controller controls the temperature alarm and time display, adjustment. Adopting high precision DS18B20 as a temperature sensor, realize real-time detection and acquisition of the environmental temperature, display temperature and time by 12864 LCD, alarm when the real time temperature is higher than the temperature alarm upper limit or lower than the lower limit by using the buzzer. By infrared remote control can modify the temperature alarm upper limit and lower limit, the clock time parameter and set Alarm clock. The innovation of this design is to increase the development of the PC by using VC 6.0, display clock, thermometer and video interface on computer, constitute a friendly man-machine interface. So this system has very high practical value.
