Description

This invention relates to the field of equipment maintenance, and more particularly to equipment maintenance methods, apparatus, and systems. As science and technology advance, various devices are applied to different aspects of daily life and production. Currently, after a device malfunctions, after-sales service technicians need to visit the customer's home, inspect and verify the information about the malfunctioning device, locate the faulty part, and then order and provide the part to the supplier. The general procedure for after-sales service technicians to visit the customer's home, inspect and verify the malfunctioning device, and locate the faulty part is as follows: After-sales service technicians, based on their experience, manually remove and inspect equipment on-site, and provide the equipment model number and parts information to the manager. The manager then searches for the part ID using the equipment exploded view diagram on the equipment management website based on the provided information, and further registers it on the parts inventory website to search for parts inventory information and prices using the part ID, and provides this feedback to the after-sales service technician. In recent years, several technologies have emerged that support equipment management and maintenance based on virtual displays. For example, by setting virtual display marks on equipment, users can scan these marks with a mobile phone terminal to view the equipment's operating information. It should be noted that the above introduction to the technical background is merely provided to facilitate a clear and complete explanation of the technical content of the present invention and to make it easier for those skilled in the art to understand. Since these technical details are described in the section on the background art of the present invention, they cannot be considered publicly known to those skilled in the art. However, the inventors discovered that manual inspection, repair, and maintenance methods, which primarily rely on experience to remove and inspect equipment, are inefficient, time-consuming, and make repairs to hidden faulty equipment and conduits more difficult and time-consuming. Furthermore, even with the introduction of virtual display technology, the process is usually complex. For example, in the case of the conventional technology described above, it is necessary to set virtual display marks for each piece of equipment, resulting in a complex and costly process. To solve at least one of the above problems, embodiments of the present invention provide a method, apparatus, and system for maintaining equipment, which create and display a simulation scene based on an engineering model of the equipment's installation location, assist maintenance workers in identifying target equipment in the simulation scene, and display relevant information about the target equipment at the site where the target equipment is located, assisting maintenance workers in maintaining the target equipment. In this way, by forming a maintenance simulation scene based on an engineering model, maintenance workers can more easily identify target equipment that requires maintenance, and by displaying relevant information about the target equipment and simple interaction with the simulation scene at the equipment site, maintenance workers can more quickly identify target parts that require maintenance on the target equipment. Therefore, in addition to effectively improving maintenance efficiency, the simulation scene helps maintenance workers inspect and repair hidden equipment. A first embodiment of the present invention provides a method for maintaining equipment, which includes: obtaining an engineering model of the equipment's mounting location; creating and displaying a simulation scene based on the engineering model and assisting a maintenance worker in identifying a target equipment in the simulation scene; and displaying relevant information about the target equipment based on the simulation scene at the site where the target equipment is located and assisting the maintenance worker in maintaining the target equipment. A second embodiment of the present invention provides a device for maintaining equipment, comprising: acquisition means for acquiring an engineering model of the equipment's mounting location; first display means for creating and displaying a simulation scene based on the engineering model and assisting a maintenance worker in identifying a target equipment in the simulation scene; and second display means for displaying relevant information about the target equipment based on the simulation scene at the site where the target equipment is located and assisting a maintenance worker in maintaining the target equipment. A third embodiment of the present invention provides a maintenance system for equipment, comprising the apparatus described in the second embodiment of the present invention and a detection de
