With the increasing demand for fresh agricultural products, cold chain logistics for frozen storage of vegetables, fruits andmeat has also entered a period of rapid development. The construction of cold chain logistics training room based on Beidou technol-ogy is very important for the cultivation of cold chain logistics technology and management professionals. This paper focuses on theanalysis of the construction of cold chain logistics engineering technology training room based on Beidou technology, integrates Bei-dou technology, big data, Internet of things and mobile Internet with cold chain logistics technology, and develops the core contentof the training room - cold chain logistics big data real-time monitoring platform, i.e. cold chain logistics positioning, tracking anddistribution system. Through this platform, students can be familiar with and understand the process of Beidou positioning trackingdata collection, the law of data change, the role of data on cold chain logistics management and so on. The construction of the labora-tory meets the needs of cold chain logistics transformation and upgrading, and also provides support for accelerating the populariza-tion and application of Beidou satellite navigation system。
