医用冰箱及冷库无线报警系统的电路设计

摘要

A simple and high-efifciency wireless alarm system for medical refrigerator and cold storage was designed. This paper introduced the circuit design of the extension set in the aspects of coding circuit, transmission circuit, detection circuit for door opening of the refrigerator and so on as well as the circuit design of the main engine in the aspects of receiving circuit, decoding circuit and so on. The results of fault response tests for the system were also discussed in this paper.%设计了一种简易高效的医用冰箱及冷库无线报警系统。本文主要从编码电路、发射电路、冰箱开门检测电路等方面介绍了该系统的分机电路设计，从接收电路、解码电路等方面介绍了主机电路设计，并阐述了该系统的故障响应测试结果。
