[0002] The construction of digital twin water conservancy projects is the main measure for smart water conservancy construction. Inspection and supervision of water conservancy project equipment is one of the main daily tasks of engineering management units. Generally, the units of hydropower stations are large in size, with numerous related equipment and facilities, and the workload of inspection and supervision is very large.

[0003] The equipment inspection method of the existing technology is generally that the equipment inspection staff carries the inspection form or the inspection management system handheld terminal, follows the preset inspection route, inspects and registers the equipment that needs to be inspected on the inspection route, and after the inspection, it is generally necessary to verify the completion of the inspection task and the operation of the inspection equipment; in addition, in order to improve the efficiency of the inspection, the existing technology also uses video surveillance technology as an auxiliary, but for the inspection task, on-site inspection by personnel is necessary and cannot be replaced.

[0004] The defects of the prior art are:

[0096] The present invention is further explained below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

Among them:

[0099] The inspection record statistics module is used to display the distribution of inspection routes as a whole, or to display the distribution of inspection routes independently by floor, or to query the inspection results of inspection tasks, or to perform visual replay of inspection tasks.

[0107] The floor inspection route display submodule is used to independently display the distribution of inspection routes by floor.

[0108] The conditional query submodule performs query operations on the results of the inspection tasks according to the query conditions.

[0109] The inspection task association submodule is used to display the floor information associated with the query results according to the queried inspection task.

[0110] The inspection route and inspection point spatial position display module is used to synchronously locate the spatial position of the inspection device or the inspection point corresponding to the inspection device when performing other query operations.

[0111] The inspection task visualization dynamic replay submodule is used to visualize the inspection tasks that have been completed.

[0112] The inspection specification management module is used to query the normal operating standards of any equipment in the inspection system based on the inspection point or inspection equipment, and perform visual positioning operations.

[0113] In this specific embodiment, the inspection specification management module includes an inspection point and inspection equipment query submodule and a visualization display submodule. Among them:

[0114] The inspection point and inspection equipment query submodule is used to query the normal operation standard of any equipment in this inspection system based on the inspection point or inspection equipment as the query condition.

[0115] The visualization display submodule is used to perform a visualization positioning operation on the queried inspection point or inspection equipment. The result of the visualization positioning operation includes the spatial position of the queried inspection point or inspection equipment displayed in a visualization form.

[0116] The video intelligent inspection module is used to link video surveillance equipment, or for a specific inspection device, directly retrieve the relevant video images of this inspection device or the inspection point corresponding to this inspection device, or further check the inspection device that is operating abnormally, and synchronously locate the spatial position of this inspection device or the inspection point corresponding to this inspection device.

[0117] In this specific embodiment, the video intelligent inspection module includes an inspection route and inspection point query submodule and a visual positioning submodule. Among them:

[0118] The inspection route and inspection point query submodule is used to query the inspection route or inspection point.

[0119] The visualization positioning submodule is used to visualize the spatial position of the inspection point and link this spatial position with the relevant video images of the inspection point.

[0125] A three-dimensional visualization hydropower station universal inspection method using a three-dimensional visualization hydropower station universal inspection system comprises the following steps:

[0126] like Figure 2a to Figure 2d As shown, S100. Install positioning system equipment and video monitoring equipment in the hydropower station. The positioning system equipment includes UWB positioning base station, NFC positioning point, and personnel NFC handheld terminal.

[0127] In this specific embodiment, in S100, UWB positioning base stations and NFC positioning points are used in conjunction with personnel's NFC handheld terminals to achieve personnel positioning.

[0128] When the distance between the inspection personnel and the UWB positioning base station is less than the manually preset personnel-base station distance threshold, the UWB positioning base station will automatically locate the personnel and push the relevant inspection tasks.

[0129] When the inspection personnel touch the NFC positioning point with the personnel NFC handheld terminal, the NFC positioning point will locate the personnel and push the relevant inspection tasks.

[0130] It should be noted that the role of the positioning system equipment is to locate the personnel of the inspection staff, which involves the influence of the internal structure of the building on the positioning effect, resulting in the technical solution of the UWB positioning base station plus the NFC positioning point adopted in the present invention, and its principle is:

[0131] For areas with many complex devices and narrow passages, the role of UWB positioning base stations is relatively limited. It is also prone to signal blind spots and the possibility of misjudgment. Therefore, for such areas, NFC positioning points are deployed to achieve personnel positioning. Patrol personnel achieve positioning by touching the personnel's NFC handheld terminal to the NFC positioning point.

[0132] For areas with neatly arranged equipment or spacious rooms, UWB positioning base stations are deployed to automatically locate the personnel and push related inspection tasks when the inspection personnel are a certain distance away from the positioning base station. This saves the personnel from having to touch the equipment once, making it more convenient.

[0133] S200. Establish a BIM model of the hydropower station plant and an equipment BIM model of the inspection equipment.

[0134] In this specific embodiment, in S200, BIM software is used to establish a factory building BIM model and an equipment BIM model.

[0135] The model accuracy of the factory building BIM model and the equipment BIM model is consistent with the manually preset equipment inspection requirements.

[0136] The factory building BIM model is split into individual units according to the equipment floors based on the equipment inspection requirements.

[0137] The factory building BIM model and equipment BIM model are both loaded into the WebGL 3D engine platform.

Based on the factory building BIM model and equipment BIM model established in S200, set up the inspection record statistics module, inspection specification management module, video intelligent inspection module, forecast and task release module according to the deployment plan of the inspection points.

[0141] Then the inspection record statistics module, inspection specification management module, video intelligent inspection module, forecast and task release module that have been set up and initialized are connected to the positioning system equipment and video monitoring equipment.
