101. and constructing a three-dimensional twin railway virtual scene based on the engineering internal structure building information model and the external environment geographic information system.

The building information model (Building Information Modeling, BIM) is a three-dimensional building model built and managed by taking various relevant information data of a building engineering project as a basis, and the three-dimensional building model simulates real information of a building through digital information, has the characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimality and diagonality, and is composed of complete information, and is easy to integrate information of all sides, thereby facilitating engineering and management such as planning, design, construction, operation and maintenance of a building life cycle.

The geographic information system (Geographic Information System, GIS) is a special and very important spatial information system, and under the support of a computer hard and software system, the technical system for collecting, storing, managing, calculating, analyzing, displaying and describing the related geographic distribution data in the whole or part of the earth surface (including the atmosphere) space is realized.

BIM and GIS are information simulation technologies, BIM contains a large amount of building information data, and displays the self-frame and internal detailed composition of the building in a three-dimensional image form, thereby providing a good platform for the whole life cycle management of the building engineering. The GIS contains a large amount of surrounding scene information, and based on geographic information data, the external space condition of the building is shown. The BIM and the GIS are fused, so that perfect combination of an engineering internal structure and an external environment is realized, a three-dimensional twin railway virtual scene is constructed, and a railway and surrounding environment scene can be restored more truly.

The three-dimensional twin railway virtual scene is a twin environment for constructing a track and surrounding buildings in a 1:1 mode, and the track trend can be seen in the three-dimensional twin railway virtual scene, and the position distribution of foundation components such as piers, roadbeds, culverts, sound barriers, overhead beams, channel doors and the like is realized. And clicking on each component, the underlying information can also be seen. For example: pier, basic information includes: bridge number, bridge name, pier number, pier height and mileage.

And the three-dimensional twin railway virtual scene also comprises a live-action roaming function, so that operations such as arbitrary ascending, descending, upward looking, overlooking, left turning, right turning, double-click positioning of a mouse and the like in the scene can be realized, and the three-dimensional twin railway virtual scene has comprehensive functions and is convenient to operate. In the scene, the right key can be double-clicked to rotate the whole scene, so that the user can watch the whole situation in all directions; a double click of the left button may be performed to quickly fly to a specific location.

And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a random access Memory (RAM, randomAccess Memory), a magnetic disk, or an optical disk, or other various media capable of storing program codes.

In another aspect, the present invention also provides a computer program product comprising a computer program storable on a non-transitory computer readable storage medium, the computer program when executed by a processor being capable of performing the railway personnel positioning method provided by the above methods, the method comprising: constructing a three-dimensional twin railway virtual scene based on the engineering internal structure building information model and the external environment geographic information system; receiving positioning inquiry information, inputting the positioning inquiry information into the three-dimensional twin railway virtual scene, and outputting real-time distribution results of personnel and vehicles; determining the regional information and the movement track of the person and the vehicle based on the real-time distribution result; prompting and marking the personnel and the vehicle when the moving track comprises an illegal track and/or the area information comprises a dangerous area; when the personnel and vehicles carrying out the prompt and marking give an alarm, responding to the alarm and generating an emergency plan; and adjusting the display picture to an alarm sending position based on the emergency plan, and adjusting the emergency plan by combining the real-time picture of the alarm sending position.

In yet another aspect, the present invention also provides a non-transitory computer readable storage medium having stored thereon a computer program which when executed by a processor is implemented to perform the railroad personnel positioning method provided by the above methods, the method comprising: constructing a three-dimensional twin railway virtual scene based on the engineering internal structure building information model and the external environment geographic information system; receiving positioning inquiry information, inputting the positioning inquiry information into the three-dimensional twin railway virtual scene, and outputting real-time distribution results of personnel and vehicles; determining the regional information and the movement track of the person and the vehicle based on the real-time distribution result; prompting and marking the personnel and the vehicle when the moving track comprises an illegal track and/or the area information comprises a dangerous area; when the personnel and vehicles carrying out the prompt and marking give an alarm, responding to the alarm and generating an emergency plan; and adjusting the display picture to an alarm sending position based on the emergency plan, and adjusting the emergency plan by combining the real-time picture of the alarm sending position.

The apparatus embodiments described above are merely illustrative, wherein the elements illustrated as separate elements may or may not be physically separate, and the elements shown as elements may or may not be physical elements, may be located in one place, or may be distributed over a plurality of network elements. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment. Those of ordinary skill in the art will understand and implement the present invention without undue burden.

From the above description of the embodiments, it will be apparent to those skilled in the art that the embodiments may be implemented by means of software plus necessary general hardware platforms, or of course may be implemented by means of hardware. Based on this understanding, the foregoing technical solution may be embodied essentially or in a part contributing to the prior art in the form of a software product, which may be stored in a computer readable storage medium, such as ROM/RAM, a magnetic disk, an optical disk, etc., including several instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the method described in the respective embodiments or some parts of the embodiments.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
