Detailed Description
The technical scheme of the invention is further specifically described below through examples and with reference to the accompanying drawings.
Example 1: as shown in the figure, the intelligent billing method and system for the overhaul work ticket of the transformer substation comprise seven parts, namely a work task input module 101, a work interval determining module 102, a device state judging module 103, a dangerous point analyzing module 104, a safety measure arranging module 105, a manual checking module 106 and a work ticket intelligent output module 107.
The work task input module 101 inputs maintenance work tasks to be carried out into the substation work ticket intelligent billing system by a work ticket billing personnel.
Further, in view of the fact that the overhaul work of the transformer substation is mainly divided into two types of single-interval overhaul and centralized multi-interval overhaul, the arrangement logic of safety measures of the transformer substation is different, and therefore the transformer substation work ticket intelligent billing system is provided with a selection window for single-interval overhaul and multi-interval overhaul in the first step.
The working interval determination module 102 is composed of two methods, manual determination and intelligent determination.
Further, the manual determination is that the working interval is determined by a working ticket issuer according to the equipment for carrying out maintenance work and the corresponding working interval thereof in a clicking mode.
Further, the intelligent determination is based on text classification technology to realize intelligent determination of the working interval to be overhauled. The intelligent billing method and system for the working ticket of the transformer substation firstly analyzes and summarizes the characteristics of text information such as maintenance work tasks, then utilizes a distributed text learning tool word2vec, simultaneously combines the technical nouns of the power system, automatically learns semantic information, and represents the professional words related to the maintenance work tasks by using low-dimensional dense vectors. And then, establishing a circular convolution neural network, and intelligently classifying text information of the overhaul work task based on an end-to-end network structure of the circular convolution neural network.
Further, the intelligent billing system for the transformer substation work ticket takes a 110kV transformer substation as an example, and five levels are divided into the intelligent billing system, as shown in fig. 3 in the description of the drawings. The first hierarchy is a substation layer, and the hierarchy corresponds to each substation. The second level is a regional level, and 110kV substations can be divided into three main categories, 10kV part, 110kV part and transformer part. The third level is a type layer that can be divided into various service interval types of lines, capacitors, voltage changes, ground changes, etc. The fourth layer is a spacer layer, and specifically corresponds to a corresponding device interval, for example, a certain line interval of 110kV, a certain line switch cabinet interval of 10kV, or a certain capacitor interval of 10kV, etc. The fifth level is a device layer, and the level corresponds to a specific device, such as an upper cabinet door, a middle cabinet door and a lower cabinet door, which are spaced by a certain line of switch cabinets of 10 kV. Through the division of five layers, the specific equipment needing to be subjected to maintenance work can be accurately positioned. In particular, the above-mentioned intelligent determination method can make intelligent determination on five levels of information by using text classification technology, and manual determination requires that the work ticket issuer make item-by-item determination by means of manual mode.
Further, if the maintenance work is performed as a single interval maintenance type, one of the corresponding spacers is selected and only one of the spacers is selected. Similarly, if the maintenance work is a multi-interval maintenance type, the corresponding spacer layer can be selected in multiple ways.
Further, due to the consistency of arrangement of safety measures of overhaul work of the same type of equipment, the intelligent billing system for the transformer substation work ticket divides a state layer, an safety measure layer and a dangerous point layer after the equipment layer based on the characteristics. Corresponds to the equipment state judging module 103, the dangerous point analyzing module 104 and the safety measure arranging module 105 in the system.
The equipment state judging module 103, the dangerous point analyzing module 104 and the safety measure arranging module 105 all collect working interval information from the working interval determining module 102 and simultaneously perform logic criteria of the corresponding modules.
The equipment state judging and identifying module 103 determines the outage state of equipment to be overhauled by the working ticket intelligent billing system according to the working interval information, and specifically comprises cold standby, switch overhauling, line overhauling, switch line overhauling, capacitor overhauling and the like. And outputting the opening and closing conditions of the corresponding breaker, the disconnecting switch, the grounding wire and the grounding disconnecting switch in the shutdown state according to the shutdown state of the equipment and the power system knowledge graph. The part specifically corresponds to two items of a circuit breaker (switch), a disconnecting switch (disconnecting link) and a grounding wire which are to be connected and a grounding disconnecting link which are to be connected in a first working ticket of the transformer substation.
The dangerous point analysis module 104 determines high-voltage incoming call points which possibly generate dangers to maintenance work according to the working interval information by the working ticket intelligent billing system. This portion corresponds specifically to the entry of the first ticket of the substation where the live portion or notice is reserved.
The safety measure arrangement module 105 automatically generates corresponding safety measures by the work ticket intelligent billing system according to the work interval information, including stop steps, high-voltage danger, closing prohibition, work by someone, work here and the like which need to be hung. The part specifically corresponds to an item of 'shielding to be installed, a sign board to be hung, measures for preventing false collision of a secondary circuit and the like' in the first working ticket of the transformer substation.
Furthermore, when the corresponding safety measure arrangement scheme is output, the intelligent ticket billing system can automatically count the required obscuration and the number of the nameplates in the arrangement scheme, so that convenience can be provided for operation and maintenance personnel to arrange and arrange the safety measures, and the operation and maintenance personnel can be facilitated to strengthen the management and resource allocation of the nameplates of each transformer substation.
The manual verification module 106 verifies the work ticket issued by the work ticket issuing system by a work ticket issuing person. If the staff of the work ticket issuing personnel find that the work ticket has a small range of errors, the manual modification mode can be selected to correct the work ticket. If the job ticket issuer finds that there is a large error in the job ticket, the job interval determination module 102 may be returned to and the job ticket issuing operation may be repeated.
The intelligent ticket output module 107 outputs corresponding tickets by the intelligent ticket issuing system according to the first/second ticket format requirement of the transformer substation.
Furthermore, when a new work ticket is successfully issued, the intelligent work ticket issuing system can automatically generate a visual display diagram of corresponding safety measure arrangement according to the content of the safety measures in the work ticket, thereby providing convenience for operation and maintenance personnel to correctly arrange the safety measures.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
