📦 单片机的多点温度显示和报警系统设计 - 免费下载

本文介绍以单片机为核心的多点温度显示与报警系统的设计,硬件电路由复位电路、测量电路、键盘输入电路、温度显示电路以及报警电路构成。系统通过键盘输入电路将预设温度临界值输入单片机,由多个DS18B20以多点组网的方式实现温度的多点测量,并将测量的实时温度反馈给单片机,单片机通过温度显示电路显示,当温度超过临界值时通过报警电路进行报警反馈。

This paper introduces the design of multi-point temperature display and alarm system with single chip as the core. The hardware circuit consists of reset circuit, measurement circuit, keyboard input circuit, temperature display circuit and alarm circuit. The system inputs the preset temperature threshold value into the single-chip microcomputer through the keyboard input circuit, and the multipoint measurement of the temperature is realized by multiple DS18B20s in a multi-point networking manner, and the measured real-time temperature is fed back to the single-chip microcomputer, and the single-chip microcomputer displays through the temperature display circuit, When the temperature exceeds the critical value, the alarm circuit is used for alarm feedback.
