Dairy products are popular among consumers because they are rich in nutrients such as protein, fat, vitamins and minerals. The shelf life of dairy products at room temperature is usually relatively short, so the production, transportation, storage and sales of dairy products require the participation of cold storage, refrigerated trucks and other cold chain equipment to ensure the quality and nutrition of dairy products. Cold chain logistics has the advantages of ensuring freshness and nutrition of dairy products, reducing deterioration loss of dairy products, extending the storage period of dairy products and thus expanding the scope of sales, and its influence on the consumption of low-temperature dairy products market is increasing. One of Humpback Whale's clients is a leader in the domestic dairy industry with a nationwide marketing network, and has over 50 leased warehouses that require dairy product cold storage monitoring, as well as monitoring the cold chain links of major production plants and intercity distribution. Humpback Whale's dairy cold storage freezer temperature and humidity monitoring solution helps the user to control the quality of their own products well and continues to be welcomed by consumers.

Challenge

As the leading company of the dairy industry, the customer's service network penetrates widely, and all products require high-level cold chain management capabilities, but the problems of inadequate cold chain logistics information system and imperfect dairy cold chain logistics information platform caused by the lack of information monitoring and timely use of information feedback plague the customer's daily production. The customer produces a wide range of dairy products, and the difference between cold chain logistics and storage is obvious, covering different levels of high temperature, medium temperature, low temperature and ultra-low temperature, etc. Items with different temperature requirements are kept in different temperature cold storage for short-term or long-term storage. Refrigerated food requires a relatively stable temperature in the refrigerated warehouse, excessive temperature fluctuations will cause food spoilage. Users of the sales network throughout the country, the rented outside the cold storage also exists relatively obvious differences, the new cold storage more rigid polyurethane or polystyrene foam insulation sandwich panel, with high-pressure foaming process once infusion molding, insulation effect is good, but due to the type of library panels are mostly color plastic steel, salt steel or embossed aluminum, etc., affect the wireless signal transmission, there is a certain impact on the transmission of information.

Solution

According to the actual situation of customers, Humpback Whale helps users establish a complete cold chain logistics management system through the collaboration of Whale Dart hardware and Whale Cloud platform. Through the platform, it establishes information sharing mechanism, improves logistics information, promotes the application of physical network and big data technology within the enterprise, and realizes the intelligence of cold chain logistics information between internal vehicles and outsourced transporters as well as own cold storage and leased cold storage. The data transmission of cold chain information is carried out through LoRA gateway and 4G communication, and the temperature and humidity changes of vehicles and cold storage are monitored in real time through portable temperature and humidity recording equipment and LoRA gateway and probe in cold storage, and the causes of temperature and humidity changes can be identified through statistical analysis to facilitate clear responsibility for quality accidents and regulation of the transportation and storage environment of cold chain logistics. The products involved in this case include LoRa gateway, external temperature probe, internal temperature and humidity probe, portable temperature recorder, ultra-low temperature portable temperature recorder, ultra-low temperature temperature probe, etc.
