[0063] The high-precision modeling of the equipment is performed by using a three-dimensional modeling software, and the basic information of the main equipment and auxiliary equipment is simulated and displayed in the form of text, video and three-dimensional animation, so as to demonstrate and explain the basic information of the equipment, such as the name, type, purpose and characteristics.

[0064] The three-dimensional model of the whole plant is constructed by using a three-dimensional modeling tool, and the physical distribution and the running state of the equipment of the whole plant are displayed in three dimensions. The panoramic and entity description and reflection of the entity relationship, position and hierarchical description between the equipment are provided to accurately display the panorama of the whole plant.

[0065] The three-dimensional scene simulation of the key information, such as the general appearance, civil engineering, structure, spatial entity position of the main equipment and the arrangement of the pipeline and valve, is performed.

[0066] The user can click the system or equipment in the scene in the scene roaming, the three-dimensional model outline of the system or equipment is highlighted, indicating that the current system or equipment is selected, the composition and function thereof can be introduced, and the basic parameters, technical information and real-time data can be viewed, which is helpful for the overall understanding of the equipment of the whole plant.

[0071] Through the data collection of the current running state of the enterprise rotating equipment, digital management and the full participation of the equipment management personnel, the management of the equipment running state is realized to be known in mind and the equipment under jurisdiction is in dynamic control. Meanwhile, a working platform is provided for all equipment management personnel to provide the equipment running state monitoring level warning, professional analysis reference, processing process and final effect sharing of the equipment under jurisdiction, thereby improving the work efficiency.

[0072] The three-dimensional platform provides auxiliary tools, including model scattering tool, model splitting tool, model exporting tool, cutting tool, vector preprocessing tool, model mapping optimization tool, vector mapping tool, etc.

[0073] In the project, sometimes a single model is too large to affect the loading speed of the model, or for other reasons, the model needs to be decomposed according to the minimum composition. At this time, a model decomposition tool is needed. This tool is the model scattering tool. This tool decomposes the model according to the minimum composition, saves it to a directory, and generates a list file of the relative position of the model. In this way, the platform only needs to process small files when loading, and the performance will be improved to a certain extent.

[0074] The project requirements often contain some device query, classification display and other functions. These devices that need to be queried or specially displayed are called key devices. In order to support the implementation of program functions, key device models need to be stored independently in the system, that is, each key device model needs to be saved as a model file independently.

[0075] Supporting batch processing and uploading of different sources, different formats of data, documents and three-dimensional models of digital handover. At the same time of uploading the system, it can automatically integrate these information, establish various association relationships between data, documents and three-dimensional models based on the power plant object as the core, complete information integration, and realize that through the power plant object number, all associated information such as three-dimensional model, P&ID, layout drawing, data table, etc. of the device can be associated.

[0076] Since the model maker cannot accurately grasp the division of key devices, the model maker does not consider the problem of separate saving of key devices when making models, and only needs to group and export the entire scene model according to the requirements. The splitting of key devices is completed by the implementer according to the actual situation on site through the model splitting tool.

[0077] Data input data format:

[0078] IVE: Model file, which is also the direct object to be operated.

[0079] ME: Scene state save file, open to continue operation.

[0080] Data output data format:

[0081] Data format:

[0082] IVE, OSG: exported model file.

[0083] AVE: model texture file, located in the textures directory at the same level as the exported model.

[0084] DEVICE.INI: exported model file information record file, including: device name, model name, bounding box radius, center point.

[0085] ME: scene state save file.

[0086] Model export is through the installation of OpenSceneGraph plug-in, restart 3DSmax, click file menu in the Export export option, pop-up model options dialog box.

[0087] Vector data is an important part of geographic information system, in order to meet the needs of three-dimensional system, Lang Kun wisdom needs to carry on the resampling processing and format conversion of the terrain fitting of the conventional format of vector data, this part of work through the vector data preprocessing tool is completed.

[0088] The vector data processing flow is shown in Figure 1

[0089] For the model data is very big station, a large number of models loaded at one time, contains a large number of map files. Often will lead to a large amount of memory is occupied. In order to be able to reduce the occupation of memory, make the model of one-time loading quantity reduction is a simple and feasible method. Through the gradual increase of the distance of the model makes the memory load will not be very large in a short time.

[0090] Model map optimization tool is to carry on the batch processing of model, according to the size of the model set distance control, application of different scale of model's apparent and hidden control.

[0091] Personnel positioning management is one of the key links of the project, through the personnel positioning management can supervise and data statistical analysis of the whole plant personnel, realize the effective management of the scene operation, personnel protection management.

[0092] Personnel positioning management will use UWB communication technology to realize the positioning management of personnel. UWB communication technology is a kind of carrierless communication technology, using nanosecond to picosecond level of non-sine wave narrow pulse transmission data, with strong anti-interference ability, high transmission rate, large system capacity, small transmission power, low human influence, etc., can meet the functional demand application of Yiguang power generation in its complex site conditions.

[0093] ​The personnel positioning system sends out pulse data packets by the positioning tags worn by the personnel. The data packets are composed of a series of ultra-wideband pulses. Since the tags do not send out pulses at the same time and the time for each tag to send out a pulse is very short, the probability of continuous data packet collision is very small, so hundreds to thousands of positioning tags can be processed in the same area; the positioning base stations receive the pulse data packets sent out by the positioning tags. The base stations are usually deployed at the edges of the positioning area. Each base station uses a highly sensitive, high-speed, short-pulse listener to measure the accurate time of each pulse data packet to its antenna. The ultra-wideband pulse has a wide bandwidth, so the base stations can measure the time of arrival of the pulse data packet to the level of nanoseconds. The central switch accurately determines the actual position of a positioning tag according to the coordinates of the base stations, the time difference of the pulse data packets arriving at each base station, and a multi-path algorithm.

[0094] The base station list interface can set the group of the base station. After a new group is created, the name of the group is maintained, and the spatial picture of the current group is uploaded in all operations. The specific position of the base station is automatically displayed on the spatial picture of the current group by the spatial parameter attribute of the base station itself, and the base station list is refreshed on the left side of the picture.

[0095] Traditional positioning is based on a plan view and uses GPS and other technologies to position in a two-dimensional space, which has low accuracy and is difficult to show the personnel distribution in a three-dimensional space.

[0096] The personnel positioning system of the project mainly fuses three-dimensional simulation technology and personnel positioning technology to realize three-dimensional positioning in a three-dimensional space. Through accurate positioning of the XYZ coordinates of the personnel and in combination with a three-dimensional model, the real-time spatial position of the personnel can be accurately positioned, and the accuracy of personnel positioning is greatly improved.

[0097] The RedBat positioning system based on UWB technology is used in the scheme.

[0098] UWB (Ultra Wide Band) is a kind of carrierless communication technology that transmits data by using non-sine wave narrow pulses of nanoseconds to microseconds. UWB modulation uses fast rising and falling pulses with a pulse width of ns level. The spectrum covered by the pulses is from direct current to GHz, and no RF frequency conversion is required for conventional narrowband modulation. After pulse shaping, the pulses can be directly sent to the antenna for transmission. The spectral shape can be adjusted by the very narrow continuous single pulse shape and the antenna load characteristics. The UWB signal is sparsely distributed on the time axis, and the power spectral density is very low.

[0099] Because of its unique technical characteristics, UWB can replace most application scenarios of RFID, Bluetooth, ZigBee and other technologies. It is considered by the industry as the most advanced radio frequency identification and positioning technology.

[0100] RedBat does not interfere with the spectrum of commonly used RFID, Bluetooth, WiFi, ZigBee, GPS, 3G, 4G, etc., which makes it possible to mix with various communication technologies.

[0101] Redbat uses the way of accurate measurement of the arrival time of the pulse signal, which makes the receiver more accurate in time perception of the source. Therefore, through the electromagnetic propagation rate and time, the distance between the transmitter and the receiver can be accurately calculated, with an accuracy of + / - 5 cm. The accuracy of the later precise positioning can reach 10-30 cm.

[0102] The pulse transmission frequency of RedBat is adjustable, and the highest frequency of a single transmitter can reach 2000Hz. In a typical RedBat positioning system, the refresh rate for asset positioning is generally selected at 0.1Hz-1Hz; the refresh rate for personnel positioning is generally selected at 1Hz-5Hz, and can be higher in special scenarios; the refresh rate for vehicle positioning is generally selected at 5Hz-10Hz.

[0103] Based on the calculation of 1Hz refresh rate per tag, a single area can support up to 240 tags, and the whole area is not limited by this.

[0104] The working frequency band of RedBat is 3.1-10.6GHz, and it is a direct pulse modulation technology without carrier, which is different from the modulation method of some existing communication technologies. It will not be affected by the problem of carrier interference. At the same time, the radiation power of UWB is very low, generally one thousandth of that of a mobile phone, so it will not cause interference to commonly used electronic instruments and communication equipment.

[0105] RedBat positioning technology combines the characteristics of radio frequency identification and precise positioning, so it can support multiple positioning modes.

[0106] The visual safety supervision method is to set up an electronic fence for dangerous areas, special areas and sources of danger. These areas are prohibited for personnel or only allow part of the personnel to enter or approach, so as to avoid safety accidents. When personnel enter or leave the electronic fence, the electronic fence will alarm; the alarm color is divided into red, blue, green, orange and yellow.

[0107] When the personnel tag does not enter the electronic fence area, the electronic fence alarm color shows green to remind others not to enter;

[0108] When the personnel tag does not enter the electronic fence area, the alarm color shows red to drive the personnel away;

[0109] When the personnel tag does not enter the electronic fence area and is driven away by the alarm, the personnel leave the electronic fence area, the electronic fence shows orange within five minutes after the personnel leave to remind others not to enter;

[0110] When the personnel tag passes through the allowed entry electronic fence area, the alarm color is displayed in blue, i.e. it is displayed that someone is allowed to enter;

[0111] When the personnel tag passes through the allowed entry electronic fence area for 30 minutes and still does not leave, the electronic fence displays a yellow drive-off, reminding the entering personnel to leave on time;

[0112] When the personnel tag passes through the allowed entry electronic fence area for more than 30 minutes and passes through the alarm drive-off, the personnel leaves the electronic fence area, and the electronic fence displays an orange reminder that other people cannot enter within five minutes after the personnel leaves; the personnel passing through the allowed entry electronic fence area is allowed to enter for a maximum of 30 minutes under non-special circumstances; the personnel tag refers to the real-time display of the personnel in the form of a tag in the digital 3D map.
