Cold Chain Logistics (Cold Chain Logitics) generally refers to a system project that refrigerated and frozen food is always in a specified temperature environment in each link before consumption in production, storage, transportation and sale so as to ensure the quality of the food and reduce the loss of the food. The method is established along with the progress of scientific technology and the development of refrigeration technology, is a low-temperature logistics process based on refrigeration technology and by means of refrigeration technology, and avoids the phenomenon that refrigerated and frozen foods are deteriorated under the condition of overhigh temperature.
With the development of internet e-commerce technology, online shopping has become an indispensable life style of people more and more. Especially for young people, most commercial purchases are from the internet. With the development of the cold-chain logistics technology, agricultural products and fresh products also become objects of online shopping. The internet of things is an application expansion of the internet and is based on the internet technology.
Agricultural products and fresh products have high requirements on storage conditions, and in the links of production, transportation, distribution and the like, individual links are separated from monitoring. Therefore, an all-around comprehensive monitoring system and a monitoring method are established, which is particularly important for guaranteeing the quality of cold-chain logistics products.
In the past, only temperature and humidity are concerned in monitoring, but in reality, many factors are involved in safety and influence on product quality, and the factors are not monitored, so that safety holes and monitoring dead corners are caused.
In past monitoring, no distinction was made between storage conditions of different products. Because the storage environments with different levels are not set according to the product types, the temperature in the storage box is always lower than the required temperature, and other conditions are not low-carbon and energy-saving. Therefore, under such a situation, on one hand, the product quality cannot be guaranteed well, and on the other hand, energy is wasted due to the maintenance of a low temperature.
The current monitoring system cannot efficiently save and service nearby organization personnel for monitoring found problems, so that the service level is too low, and the service experience of users is not facilitated.
