The invention provides a new energy power station production data off-line synchronization apparatus and method, wherein the system comprises labels, multiple off-line synchronizers and a production data management apparatus; the labels are installed on power equipment for collecting related operation data information of the power equipment and outputting the data information; the off-line synchronizers are used for obtaining the data information collected by the labels and storing the data information or synchronizing the data information to a network, and verifying data information stored in other off-line synchronizers and storing the data information; the production data management apparatus is used for storing the data information stored in the off-line synchronizers. In this way, close contact with equipment is avoided; work convenience is guaranteed; off-line data is stored in a memory by encryption during the data recording process; and off-line data security is guaranteed. At the same time, the transmitted data is encrypted, therefore, the data can be decrypted only when arriving at an application server; off-line data secure synchronization is guaranteed; and the process of program automatic synchronization is realized.
