Abstract

The invention relates to a real-time temperature and humidity monitoring and alarm method for fixed cold-chain equipment on the basis of wireless communication. The real-time temperature and humidity monitoring and alarm method includes steps that 1), a temperature and humidity acquisition module acquires temperature and humidity information of the fixed cold-chain equipment in real time and transmits the temperature and humidity information to a CPU (central processing unit); 2), the CPU receives the temperature and humidity information of the fixed cold-chain equipment, stores the temperature and humidity information locally and regularly transmits the temperature and humidity information to a cloud platform server via a wireless communication network, the temperature and humidity information is compared to set threshold values, a local alarm is raised if the temperature and humidity information exceeds the set threshold values, and alarm information is transmitted to the cloud platform server via the wireless communication network; 3), the cloud platform server transmits the alarm information to a user in real time via a mobile communication network by various information approaches, and the user can query the temperature and humidity information of the fixed cold-chain equipment via the cloud platform server. Compared with the prior art, the real-time temperature and humidity monitoring and alarm method has the advantages of wide monitoring range, high reliability, good safety and the like.

Description

technical field [0001] The invention relates to a cold chain equipment monitoring related technology, in particular to a wireless communication-based real-time temperature and humidity monitoring and alarm method for fixed cold chain equipment. Background technique [0002] China reaches 70,000,000,000 yuan every year due to the waste that discards rotten food and causes, accounts for as much as 20% of food production total value. Some food is discarded during transportation because it cannot be kept fresh for a long time. Experts say this waste is mainly due to the lack of a "cold chain transportation" system. In the transportation of fresh, live and perishable goods, except for a small number of deaths caused by care on the way or vehicle discomfort, most of them are caused by rot. [0003] The cold chain process must rely on freezing or refrigerating equipment. The freezing or refrigerating equipment must be additionally equipped with freezing or refrigerating and heat ...
