2 is a block diagram schematically showing the overall configuration of a wind turbine maintenance apparatus according to an embodiment of the present invention.

2, a wind turbine maintenance apparatus 200 according to the present invention includes a data collecting unit 210 for receiving and storing state information of a wind turbine generator from site servers 271, 273, and 275 that manage a wind turbine generator, A database 240 for storing information on the maintenance work required for the wind turbine generator and the status information of the wind turbine generators collected by the data collecting unit 210, the status information of the wind turbine generator 240 stored in the database 240, A task selection unit 220 for selecting a first maintenance task to be performed by the user, a task scenario generation unit 230 for generating a task scenario for performing the selected task, and a task instruction sheet including the generated task scenario And a work instruction sheet issuing unit 250 that transmits the work instruction sheet to the maintenance engineer terminal 280. In addition, A verification operation for managing the results proceeding up unit 260 and / or the display unit 290 to display the relevant information may be further included.

The data collecting unit 210 may collect data on the status monitoring of the wind turbine operated in each site server from one or more site servers 271 to 273. [ The data thus collected is stored in database 240 for use in a wind turbine maintenance device.

The database 240 stores not only status information of the wind turbines collected by the data collecting unit 210, but also operation information necessary for maintenance of the wind turbine generator. In general, it is possible to store the work necessary for optimum operation of the wind turbine generator, such as the problem-solving method suggested by the manufacturer, and the inspection to be performed periodically, and a work scenario related to the work.

The work selection unit 220 determines whether maintenance is required for the specific wind turbine based on the status information and the operation information of the wind turbine stored in the database 240. If the maintenance is required, You can select tasks.

Maintenance work required for wind turbines can be classified as post-maintenance, cycle maintenance, and state-based maintenance.

Referring to FIG. 3, the screen unit 290 may display all the work instruction sheets issued by the work instruction sheet issuing unit 250 in the work instruction book list area 310. [ If only a part of the issued work instruction sheets exists and can not be seen in the work instruction sheet list area 310, only a part of the work instruction sheets can be shown. When a specific work instruction sheet is selected, a work type area 320 showing a work type of the specific work instruction sheet and a work instruction content area 330 showing a work instruction content can be displayed. That is, the screen unit 290 can simultaneously display the work instruction book list area 310, the work type area 320, and the work instruction content area 330 on one screen. The work type area 320 is a part showing information on the job type of the specific work instruction book, and includes maintenance type information, maintenance type information, position information, parts information, job title information, site manager information, and / Information and so on. Here, the maintenance type information indicates whether the operation is state-based maintenance, periodic maintenance, or post maintenance, and the maintenance type information indicates whether the job is a warranty item or a maintenance item.
