Problems solved by technology
The fuzzy mathematics method + analytic hierarchy process (AHP) in the commonly used comprehensive state evaluation method is an effective method to solve multi-criteria and multi-objective problems, but when there are many comparison factors, the judgment matrix is not easy to achieve consistency, and Difficult to adjust; the gray relational degree analysis method provides a quantitative measure for the development and change of a system, which is very suitable for dynamic process analysis, but when performing fault diagnosis, adopting different processing methods for the sequence will cause the size of the relational degree to change. change, while the associative order usually does not change

Embodiment Construction
[0077] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0078] Such as figure 1 Shown is the frame diagram of the functional modules of the portable terminal. In this embodiment, on the basis of the PWS-472 professional overhaul mobile portable terminal, the following functional modules are added: user login and user registration modules for user management, two-dimensional codes for data management, new tasks, data Input and query module. During the specific operation, after the maintenance personnel log in, scan the QR code on the transformer through the portable terminal to obtain the basic information of the transformer; create a new maintenance project, fill in the substation name, project name, project start and end date, select the project execution working group, add Maintenance tasks; enter and modify transformer maintenance data; query evaluation results and early warning suggestions, including:...

The invention relates to a transformer professional maintenance method based on a portable terminal. The method comprises the steps that 1, a transformer professional maintenance data platform is constructed; 2, data acquisition is performed on the maintained transformer by using the portable terminal; 3, the acquired data aggregate is transmitted to a far-end server; 4, assessment is performed through a transformer state discrimination and early warning model based on fuzzy comprehensive evaluation and Bayesian discrimination and early warning suggestions are given; 5, the assessment result and the early warning suggestions are transmitted to the portable terminal; and 6, the maintenance personnel maintains the transformer according to the assessment result and the early warning suggestions. The comprehensive discrimination method of the fuzzy theory + the Bayesian discrimination method is put forward, and the membership grade situation of the evaluated transformer is comprehensivelyevaluated from multiple factors so that the evaluation method of transformer professional maintenance is enabled to be more scientific and comprehensive and the accuracy of the result of transformer professional maintenance can be guaranteed; and the data required for maintenance are acquired onsite and the maintenance result of the transformer is acquired in real time in transformer maintenance.
Description
technical field [0001] The invention belongs to the technical field of power system transformer maintenance, and in particular relates to a portable terminal-based professional transformer maintenance method. Background technique [0002] The state information collection technology level of traditional power grid equipment is not high, and the key state information of some equipment cannot be obtained in real time, and the self-inspection and self-diagnosis capabilities of the equipment need to be further improved. In terms of the application of operation and maintenance information, traditional status assessment and diagnosis mainly focus on the analysis of single indicators, fail to effectively use multi-source data to achieve comprehensive research and judgment, and provide insufficient support for equipment status control and factory maintenance. [0003] The state evaluation process is a quantitative process that maps the equipment state quantity from the information sp...
