冷库温湿度检测与GSM短信报警系统的设计

Design of Temperature and Humidity Testing and GSM Short Message Alarm System in Cold Storage

中小型冷库的大量建设,延长了农产品的存储时间,为农民带来了一定的经济利润。同时,由于冷库温度和湿度的检测和控制不当,会使存储的农产品发生冻伤以及腐烂,给农民带来较大的经济损失。设计了一种基于无线的冷库多点温度和湿度的采集系统,当温度和湿度不在安全范围内时,可以利用GSM短信以及声光等进行报警,进一步提高了冷库的科学管理方法。

A large number of small and medium sized cold storages have extended the storing time of agricultural products, which brought cer- tain amount of economic profit for farmers. Meanwhile, because the incorrect detecting and controlling of temperature and humidity, the stored agricultural products would be frostbitten and decayed, that gave farmers greater economic losses. This paper presents a temperature and hu- midity detecting and controlling system based on multi-point wireless communication in cold storage, When the temperature and the humidity is not in a safe range, GSM short message and sound-light will give a alarm, which further improve the method of manage cold storages scientifically.
