Description

Technical Field

[0001] The present invention relates to the technical field of data management, and in particular to a method for managing underground substation engineering settlement monitoring data based on blockchain. Background Art

[0002] With the increasing shortage of construction land, the number of high-rise buildings in cities is increasing. In order to ensure the safe construction of construction projects, it is necessary to strengthen the monitoring work during the construction, decoration and operation stages of the main building, and establish an early warning mechanism for the settlement of high-rise buildings. Starting from the accuracy indicators and technical processes of high-rise building settlement monitoring, it is planned to combine and actually explore its application analysis in building settlement data processing. Settlement observation is generally a periodic observation, and the entire cycle lasts about 3 to 4 years; the observation period is different according to the construction stage of the monitored building. The first observation should be carried out at the beginning of the building foundation, and the settlement observation points buried on the longitudinal and transverse axes of the foundation should be monitored.

[0003] The result of the first monitoring is the key to the entire settlement observation. All subsequent observation data must be compared and analyzed with the first phase data until the entire process is completed. Therefore, the accuracy of the first phase observation is relatively high. Generally, a precision electronic level is used. The first elevation of each observation point is generally determined after 2 to 3 observations in the same period. During the construction of the building, the settlement observation should be closely followed by observation as much as possible for each layer of the structure. If the building construction increases evenly, it should be measured at least once when the load increases by 25%, 50%, 75% and 100%. If the construction is temporarily suspended during the construction process, it should be observed once when the work is suspended and when it is restarted. During the suspension period, observations can be made every 2 to 3 months. Building settlement observation technology is very important in engineering. It has the characteristics of strong professionalism, long time consumption, and susceptibility to external influences. Therefore, we must strictly measure and observe in accordance with the project design book and the current specifications of relevant projects, and appropriately use reasonable and advanced observation technology and data calculation methods to obtain more accurate measurement data, thereby accurately reflecting the actual situation of building settlement.

[0004] However, traditional settlement monitoring data management methods usually store data in a single server or database, which causes the server or database to become a vulnerable link of single point failure. If the server crashes or a hardware failure occurs, all monitoring data may be affected or even lost. At the same time, centralized storage methods usually require data to be transmitted to a central server. Especially when designing sensitive data transmission, there is a risk of data leakage and security issues. Therefore, a blockchain-based underground substation project settlement monitoring data management method that can eliminate the risk of single point failure and improve data security is urgently needed to solve such problems.
