Embodiment Construction
[0054] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0055] Such as figure 1 As shown, the reception encryption and storage process of the embodiment of the present invention are as follows:
[0056] First of all, the structural test data is received in real time. Here, various collectors are needed to collect the field data in real time, and the data is received and analyzed by the host computer. Each piece of data parsed includes the following fields: collector number, sampling value, sampling unit, and sampling time. Before storing the structural test data in the database, each field of the collected data needs to be encrypted. Different encryption methods are used for time fields and non-time fields. For non-time fields, AES encryption algorithm is used for encryption. For time fields, the encryption method is as follows: figure 2 shown. The encryptio...
