Description
Technical Field
The present invention relates to the field of blockchain technologies, and in particular, to a method and a system for processing power construction service data based on blockchains.
Background
In the construction field, the electric power construction is mainly carried out by dynamic multi-engineering three-dimensional operation, production facilities are multiple in temporary property, the operation environment is multiple in variability, personnel and equipment are multiple in mobility, dynamic collection and distribution of people, machines and materials are often formed in the construction process, the management difficulty of construction projects is increased, and the hidden danger of the safety quality of the electric power construction is buried. Strengthening and perfecting the safety quality management of construction projects is a problem that power construction enterprises attach high importance and constantly catch.
The traditional construction management system has the following problems:
1) the traditional engineering management information system generally uses a local server or a cloud server, the data security is poor, a deployed independent database needs to be maintained daily through external network connection, if account passwords are cracked or the operation is not proper, the cost of the data restoring technology is high, even the data cannot be restored after the database and backup are damaged at the same time, and the data security cannot be guaranteed.
2) The project management system, system construction, document returning hierarchical management, authorization management mechanism and the like are influenced by regional distance, uneven quality of management personnel, more man-made interference factors and the like in project management, the effective supervision of project management is poor due to loopholes in the aspect of project data safety, and the claims of right maintenance are difficult to realize if the project has accidents.
3) The engineering management informatization degree is not high, the certificate storage and management means are backward, important data generally become an information isolated island, the data cannot be directly read when other services are used, the effect of mutual communication and linkage between different systems cannot be achieved, and the technical barrier of traditional cooperation and contract management is formed.
4) The linkage capability is poor, namely when data is exchanged by engineering related parties, cross-platform development of different systems has the limitations of poor expansibility, high cost of secondary development, high risk, long period and the like, so that the data interaction processing period is long and the transparency is poor.
5) The single-point control, that is, the traditional construction management system has only one input and control point, the working efficiency is not high, and the input data efficiency and quality are low.
6) The data consistency is poor, namely in the engineering implementation process, data mastered by all construction related parties are respectively stored in own databases, the data consistency is difficult to guarantee, and the problems of 'information isolated island' and 'information asymmetry' are easy to occur.
7) The data resistance is poor, namely, engineering participants can randomly change engineering indexes, parameters, progress and the like according to the idea of maximizing the benefits of the engineering participants, so that the trust crisis among stakeholders is caused.
The construction site management is an important link in the construction project management, is concerned with the implementation effect of the construction project, and is a core area with frequent safety quality problems. A series of risk hidden dangers such as inadequate safety quality supervision, lack of supervision and tracking of core safety quality points, field communication information errors, personnel replacement, material stealing and reduction exist in a construction field. Because the refinement degree and the informatization level of the current construction site management need to be improved, the risk hidden danger often brings economic loss for power construction enterprises, and the quality safety liability risk is increased. Meanwhile, the construction site conditions are variable, part of construction contents are required to be modified frequently, information trace-leaving means convenient for retrospective tracing is lacked in the business negotiation process of power construction enterprises and partners, and the situation that the identifications of the power construction enterprises and the partners are inconsistent during acceptance and settlement often occurs. The electric power construction enterprises usually promote project progress on the premise of oral commitment of the partner due to project urgency, but due to lack of credible partner commitment certificates, historical contents of business negotiation with the partner cannot be verified afterwards, so that economic loss is suffered.
As an undertaker and a supervisor of power construction, the responsibility of a power construction enterprise is important, but due to the lack of reliable informatization system assistance, the supervision difficulty of the power construction enterprise is high and the power construction enterprise also bears great pressure in the development of actual construction projects, and the concrete performance is as follows: (1) lack of effective job site supervision and management tools; (2) construction teams and personnel management need to be promoted; (3) the key quality safety monitoring points lack reliable field informatization recording and management; (4) the matching degree of the current informatization system and a construction site is to be improved; (5) the process of consulting business lacks traceability; (6) historical engineering information is not efficiently analyzed.
Therefore, the information management system used by the current power construction enterprise has a management blind area for the above-mentioned core problems of the construction site, so that the availability of the management system is limited, the management efficiency is not high, and the management requirements of the power construction enterprise on the construction site cannot be met. Therefore, a novel informatization management method which meets the requirements of power construction enterprises and is applied to construction site management is urgently needed to assist managers in improving the management level of a construction site and preventing the safety quality problem of the construction site.
