Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of a method for positioning a physical device based on 3D modeling according to the present invention. The method for positioning the physical equipment based on the 3D modeling comprises the following steps:
step S100: and constructing a physical equipment model and a reference object model of the equipment model.
The reference object model is a building model or a partial structure model of the building model; the reference object model provides a position fix for the physical equipment model.
For example: the physical equipment is the right wall of the 3-building of a certain building in latitude and longitude coordinates, so that the building and the position of the physical equipment can be completely drawn in the 3D model; the building location is the reference.
For a physical equipment manufacturer, an equipment management library can be established, each physical equipment installation is marked, and building space of the physical world can be restored based on a physical building virtual model. Usually, a lot of physical devices are needed in a building besides water and electricity, and each physical device has a fixed position after being installed, but people who do not participate in the installation generally do not have to find the devices quickly, such as maintenance personnel. It is often necessary for the building personnel to dock to the equipment with varying degrees of assistance.
If the maintenance personnel hold the virtual model of the building, the specific structure of the building can be intuitively known.
Step S200: and acquiring the operating parameters of the physical equipment and displaying the operating parameters in a model.
Currently, the main application of 3D model display technology is to provide high-performance interactive 3D graphics rendered in any compatible Web browser through the browser WebGL. Through the 3D modeling technology, the user scene can be quickly constructed, and problems can be found in an all-around, multi-directional, low-cost and real-time positioning mode.
Therefore, some operation parameters of the physical equipment can be collected and then displayed on a control terminal or an interface in a unified mode, and management personnel can conveniently consult the operation parameters.
Such as the rotational parameters of the fan, the electricity usage parameters, the age of use, etc. The operation state of the equipment can be visually drawn through 3D modeling. Therefore, maintenance personnel and management personnel can master the physical equipment information and synchronize the material equipment information. Meanwhile, the manual distribution of maintenance personnel is facilitated.
Step S300: and displaying a path to the physical equipment according to the selected physical equipment, wherein the path is used for pushing to maintenance personnel.
The maintenance personnel can select from the building model and the physical equipment model on the handheld equipment such as a mobile phone and a tablet computer, or directly locate the specific position of the physical equipment in the building by searching the serial number of the physical equipment, and then plan a path to the physical equipment based on the position of the physical equipment. Such as for example, to monitor the route of the center to the physical device.
Maintenance personnel can conduct equal-scale scaling on the virtual model in the handheld device, and model information can be better viewed.
The 3D model is used for drawing a user scene, so that the position of the equipment can be accurately positioned and the running state can be accurately described. The 3D can accurately identify and position the equipment and control the maintenance cost of the whole scene, and the labor cost can be further reduced. And the equipment configuration indexes and the environmental indexes can be early warned on a monitoring screen according to 3D display. The problem can be rapidly positioned and found, and the 3D visualization reduces the finding cost.
Furthermore, in the process of constructing the physical equipment model and the reference object model of the equipment model, according to the environment field information, the physical equipment model and the reference object model of the equipment model can be drawn and restored by a WebGL technology to form a building model;
and drawing the physical equipment model in the building model, and drawing reference object information according to the spatial position of the physical equipment.
And 3D modeling is carried out on the surrounding environment according to the provided environment site information, and reference object information is drawn according to the space position (longitude and latitude length, width and height). For example, the location and name of a certain market can be determined according to the longitude and latitude position of the certain market.
The manager when the maintainer arrives at the site or the monitoring center can know the state of the material equipment according to the operation parameters of the material equipment. Specifically, the operation parameters of the physical equipment are acquired and displayed in a model, and before the operation parameters are displayed, the physical indexes and the operation indexes of the operation parameters of the physical equipment are set.
And obtaining the operation parameters of the physical equipment, comparing the operation parameters with the operation indexes, warning when the boundary value is reached, and diagnosing, maintaining and warning according to the physical indexes if the physical state of the surrounding environment of the physical equipment changes.
When the material equipment is in over-standard operation or abnormal operation, sound and light, short messages and mails can be given for warning, reminding or warning information or displaying the information on handheld equipment and a monitoring center of maintenance personnel.
In an embodiment, the displaying a path to the physical device according to the selected physical device includes:
planning a path from the current position or the selected position to the physical equipment according to the selected physical equipment and the current position or the selected position, and displaying longitude and latitude information of the physical equipment and description of a special position mark.
Sometimes, the maintenance personnel are not necessarily in the monitoring center, and path planning needs to be performed according to the specific positions of the maintenance personnel. The 3D building model comprises all site information, the longitude and the latitude are obtained according to the spatial position of the physical equipment, and a route between the longitude and the latitude is drawn according to the site information. And when the maintenance personnel arrive near the equipment, displaying the 3D reference object interface and displaying the position of the equipment.
And peripheral maintenance personnel can be displayed according to the geographical position information of the physical equipment to be maintained, so that unified task allocation is carried out, and convenience is provided for personnel management and control.
Furthermore, the method for positioning the physical equipment based on the 3D modeling further comprises the steps of obtaining environmental physical parameters in the building, drawing an environmental model, and prompting the influence of the current environment on the physical equipment according to the environmental model.
The environmental physical parameter may be environmental information obtained by a sensor, or may be obtained by other systems or other methods. Each physical device has certain environmental requirements for operation, and the change of the environment can also affect the operation of the physical device. Therefore, the environment model can be established to simulate a real scene more truly and help maintenance personnel to maintain physical equipment.
