Example one
Fig. 1 is a schematic flowchart of a method for determining a position of a millimeter wave base station in a venue according to an embodiment of the present disclosure. As shown in fig. 1, the method specifically comprises the following steps:
s101, acquiring structure information in the venue through scanning, and acquiring distribution positions of uplink equipment and downlink equipment in the venue.
Firstly, the use scene of the scheme can be on an intelligent terminal, such as a smart phone, a tablet computer or a desktop computer, and can also be on an internet of things platform. The method is used for determining the position of the millimeter wave base station in the venue according to the venue information.
Based on the use scenario, it can be understood that the execution subject of the application may be the intelligent terminal or the internet of things platform, and no limitation is made here.
In the scheme, the stadium can be a stadium, a football field, a basketball field or the like for carrying out sports competition or sports exercise.
The structure information may include information such as the area, shape, facility layout, and facility configuration of the venue.
The uplink device may be a device that acquires information and then uploads the information, and may include devices such as a video camera and a still camera, for example.
The downlink device may be a device for displaying information, that is, a device for receiving information transmitted by the uplink device and displaying the information to a user, and may include devices such as a television and a Light Emitting Diode (LED) large screen, for example.
The distribution position may be coordinates of the uplink device and the downlink device in the stadium, and specifically, the stadium may establish its own three-dimensional stereo coordinate system and determine a unit length, and then represent the coordinates of the uplink device and the downlink device according to the coordinate system of the stadium, which may be represented in the form of (x, y, z).
The system can be used for scanning the venue by using the laser scanner and obtaining point cloud data, and the structural information in the venue can be obtained after scanning is finished, and the structural information is reflected in the form of point cloud data. The laser scanner is mainly constructed as a laser range finder, the surface of an object is scanned at a uniform speed by guiding laser through a reflecting prism, meanwhile, a signal reflected by the surface of the object is received for ranging, and depth data is calculated through an algorithm. Before laser scanning, a mark point is usually pasted on an object, the mark point can reflect light emitted by a device, a reflected signal is received by the device, and then received data is processed. Point cloud data refers to a collection of vectors in a three-dimensional coordinate system.
After point cloud data in the venue are obtained, the positions of the uplink equipment and the downlink equipment are converted according to a three-dimensional coordinate system of the venue, and then the coordinates of the uplink equipment and the downlink equipment in the venue can be obtained, namely the distribution positions of the uplink equipment and the downlink equipment represented by the three-dimensional coordinate system are obtained.
And S102, constructing a three-dimensional venue model according to the structural information and the distribution positions of the uplink equipment and the downlink equipment.
And after the structural information and the point cloud data of the distribution positions of the uplink equipment and the downlink equipment are obtained, transmitting the point cloud data to modeling software to construct a three-dimensional venue model. And after the modeling is finished, the venue can be restored according to a certain proportion, and the three-dimensional model of the venue can be checked by putting the three-dimensional model of the venue into a visualization system. The visualization system is a theory, a method and a technology which convert data into graphs or images to be displayed on a screen by using computer graphics and image processing technology and then carry out interactive processing.
S103, determining the position information of the millimeter wave base station erected in the venue based on the three-dimensional venue model.
The millimeter wave refers to a special electromagnetic wave with the wavelength of 1 mm to 10 mm and the fluctuation frequency of 30GHz to 300GHz. Compared with the frequency band below 6GHz, the millimeter wave has the unique advantages of large bandwidth, low air interface delay, flexible and elastic air interface configuration and the like, and can meet the requirements of future wireless communication on system capacity, transmission rate, differentiated application and the like. The millimeter wave base station is a communication base station, and refers to a radio transceiver station for information transmission with a mobile phone terminal through a mobile communication switching center in a limited radio coverage area.
The position information of the millimeter wave base station may be coordinates of the millimeter wave base station set in the venue, and may also be expressed by using a three-dimensional coordinate system in the venue, which may be expressed in the form of (x 1, y1, z 1).
When the three-dimensional model of the venue is viewed by using the visualization system, the usable areas and the unusable areas in the venue can be clearly viewed. When facilities such as uplink equipment, downlink equipment, sports equipment, seats and the like are erected in a venue, the area is regarded as an unusable area, and meanwhile, aisles and the like for pedestrians to walk are also unusable areas. And the millimeter wave base station needs to be built into a usable area during construction, namely, the area which does not influence the normal facility operation of the venue, the coordinates of the usable area in the venue can be determined according to the three-dimensional stereo coordinate system of the venue, and the coordinates of the millimeter wave base station can be further determined, namely, the position information of the millimeter wave base station is determined.
On the basis of the foregoing technical solutions, optionally, after determining the location information of the millimeter wave base station erected in the venue, the method further includes:
and determining the number of millimeter wave base stations required to be erected for each piece of position information according to the uploading data volume of the uplink equipment and the downloading data volume of the downlink equipment.
In this scheme, the upload data amount may be a data amount of the uplink device transmitting the network, and is usually represented by kb, and the unit is kb/s. For example, the uplink device has an upload data size of 2000kb/s, which means that the device 1s transmits 2000kb of data to the network. The larger the uploading data quantity is, the faster the uploading of the uplink equipment is represented.
The download data size may be a data size of downloading data uploaded by the uplink device to the local by the downlink device, and is also expressed by kb, where the unit is kb/s. The larger the download data amount is, the faster the download speed of the downstream device is.
After the uploading data volume of the uplink equipment and the downloading data volume of the downlink equipment are obtained, the data are input into a visualization system, the condition that the data are uploaded by the uplink equipment and the condition that the data are downloaded by the downlink equipment are simulated along with time change through the visualization system, and the number of the required millimeter wave base stations is determined according to the attribute information (such as bandwidth, frequency band and the like) of the millimeter wave base stations. For example, the upload data volume of the uplink device and the download data volume of the downlink device are 3072kb/s, the download rate supportable by the base station is 600mb/s, and
therefore, the upload data volume of the uplink device and the download data volume of the downlink device are both 3mb/s, so that the base station can support about 200 uplink devices and downlink devices around to work simultaneously (the sum of the uplink devices and the downlink devices is 200). Therefore, the number of the millimeter wave base stations can be determined according to the number of the uplink devices and the number of the downlink devices.
In the scheme, the mode of determining the number of the millimeter wave base stations through the uploading data volume of the uplink equipment and the downloading data volume of the downlink equipment can ensure that the condition that the base stations are wasted does not occur when the number of the millimeter wave base stations is accurately determined, all equipment can be ensured to normally and smoothly operate, and the user experience is improved.
On the basis of the above technical solutions, optionally, the uplink device includes a high-definition video recording device;
the downlink device comprises a recorded data display device.
In this scheme, high definition video recording equipment can be the high definition camera of shooting sports events. The recorded data display device may be a television relaying a sporting event or an LED large screen.
According to the scheme, the uplink equipment and the downlink equipment are specifically limited, the data uploading amount and the data downloading amount can be determined more accurately according to the equipment attribute information, and the millimeter wave base station number is determined more accurately.
On the basis of the above technical solutions, optionally, under the condition that the number of the millimeter wave base stations is not less than two, the method further includes:
and determining the networking mode of at least two millimeter wave base stations and the antenna gain parameters of the millimeter wave base stations at all positions according to the structure information of the venue.
The networking mode may be a connection mode between different millimeter wave base stations, and when the millimeter wave base station is established, the millimeter wave base station may be divided into a parent base station and a child base station. The signal of the child base station is received from the parent base station, and the signal of the parent base station is stronger than that of the child base station. The parent base station may be connected to the child base station, and the child base station may be connected to the child base station. For example, if there are 3 millimeter wave base stations, 1 parent base station and 2 child base stations in a network, then 3 connections can be made in total, that is, one parent base station is connected to two child base stations, and two child base stations are interconnected.
The antenna gain parameter may be a ratio of power densities of signals generated by an actual antenna and an ideal radiating element at the same point in space under the condition that input powers are equal, and a degree of concentrated radiation of the input power by an antenna is quantitatively described, so as to measure the ability of the antenna to transmit and receive signals towards a specific direction. The larger the gain parameter, the larger the network coverage in a certain direction, but at the same time, the narrower the beam (radiation area) width, resulting in poor coverage uniformity.
After the venue structure information is determined, the networking mode of at least two millimeter wave base stations including the setting positions and the connection mode of the parent base station and the child base station can be determined in Simulink. For example, if more facilities exist on the ground of the venue to block base station signals, a parent base station and a child base station can be selected to be erected high above the ground; if the ground of the venue is open, the base station can be placed on the ground. When the personnel in the area where the base station is placed are dense, a wired connection mode can be selected, namely, signals are transmitted to the communication equipment of each base station through a transmission optical cable; the network base station is controlled by the equipment such as a mobile switching center, a base station controller and the like; and the antenna at the upper end of the iron tower of the base station completes data communication with the mobile phone of the user. When the mobile terminal is in an area with wide area and rare people and the shielding phenomenon of the shielding object is not serious, a wireless transmission mode can be selected, namely, data transmission between the base stations can be realized by utilizing a microwave mode, and the coverage is realized through a 5G network.
When a millimeter wave base station needs to transmit to a longer distance in a specific direction, antenna gain parameters can be improved in Simulink, even if equipment in the longer distance can work simultaneously; when the equipment in a short-distance and large-range area needs to work simultaneously, the antenna gain parameter can be reduced, namely, the radiation distance is reduced, and the radiation area is increased.
In the scheme, the networking mode and the antenna gain parameter of the millimeter wave base station can be determined according to the actual structure information of the venue, so that the working efficiency of the millimeter wave base station is improved, and the energy consumption of the millimeter wave base station is reduced. Meanwhile, due to the fact that the antenna gain parameters are adjusted, all devices of the venue can be guaranteed to be covered, and user experience and working efficiency of other devices are improved to a certain extent.
On the basis of the above technical solutions, optionally, determining a networking mode of at least two millimeter wave base stations according to the structure information of the venue includes:
determining the networking structure deployment of each piece of position information according to the seat arrangement partitions in the venue and the seat arrangement quantity of each partition; and determining the parent-child node relationship of each millimeter wave base station in the networking according to the specific position of each position information distributed in the venue.
In this scheme, the deployment of the networking structure may include the number, the setting position, and the connection manner of the child base station and the parent base station.
The parent-child node relationship may be a connection condition between the child base station and between the child base station and the parent base station, for example, when one parent base station and one child base station are set, the connection condition may be expressed as parent-child; when two child base stations and a parent base station are arranged, the connection condition can be expressed as child-parent, that is, after two child nodes are connected, the two child nodes are respectively connected with the parent node.
When a three-dimensional model of the venue is established in modeling software, seats in the venue are restored, namely seat arrangement partitions in the venue and the number of seat arrangements of each partition are restored, and the required millimeter wave base stations and networking structure deployment of the millimeter wave base stations can be determined according to the information. For example, 500 seats are provided in the north area of the stadium, 1000 seats are provided in the south area, and if one millimeter wave child base station can cover 600 seats, the north area can be set to be connected with one millimeter wave parent base station through one millimeter wave child base station; the south area can be firstly provided with two millimeter wave sub base stations for connection, and finally connected with a millimeter wave father base station. The reason is that the signals of the child base stations need to be supplied by the father base station, and the south area can not be completely covered by only one millimeter wave base station, so that two millimeter wave child base stations are needed to be supplied, and the child base stations are established and then connected with one father base station. After the connection is completed, if the child base station detects that a signal of a certain connected area is weak, the information can be reported to the parent base station, and the parent base station reallocates the information, namely the area is allocated to other child base stations so that the equipment in the area can normally work.
After the number of the required child base stations is determined, the relation between the required parent base station and the parent child node can be determined according to the distance between the areas. For example, if the east area has one child base station, the north area has two child base stations, and if the east area is closer to the north area, a parent base station may be arranged in the north area to simultaneously connect the child base stations of the east area and the north area, and the child base stations of the east area and the north area may also be interconnected, and the parent-child node relationship may be represented as a north child-east child-north parent, which represents the position of the child base station, and also represents the connection relationship between the parent base station and the child base station.
In the scheme, the number, the positions and the connection modes of the father base station and the child base stations can be determined more accurately by determining the deployment of the networking structure and the relationship between the father node and the child node according to the number of seats and the partitions in the venue, so that the problem that the coverage area of the base stations is repeated more to improve the construction cost is solved while the full coverage of signals in the venue is ensured, and the user experience can be improved to a certain extent.
On the basis of the foregoing technical solutions, optionally, after determining the location information of the millimeter wave base station erected in the venue, the method further includes:
according to the position information of the millimeter wave base station and the distribution positions of the uplink equipment and the downlink equipment, determining the azimuth information of the uplink equipment relative to the base station and the azimuth information of the downlink equipment relative to the base station;
and performing beam forming on the millimeter wave signals sent by the antenna array of the millimeter wave base station based on the azimuth information.
In this scheme, the direction information of the uplink device and the downlink device with respect to the base station may be expressed in the form of (relative position, distance). For example, after determining the position information (coordinate position) of a certain millimeter wave base station, if a certain uplink device is located 10 meters directly north of the millimeter wave base station, the uplink device may be represented in the form of (directly north, 10 meters).
Because the directivity of a single antenna is limited, in order to be suitable for applications in various occasions, an array formed by feeding and spatially arranging two or more single antennas operating at the same frequency according to certain requirements is called an antenna array.
The beam shape may be a shape that changes the beam of the millimeter wave signal emitted by the millimeter wave base station to a shape only for a specific direction, so as to enhance the signal in the specific direction. For example, the equipment included in a certain node is mainly responsible for collecting videos near a football goal, so that all cameras are concentrated near the football goal, and the beams emitted by the millimeter wave base station responsible for the node only face the direction of the football goal, so that the signals of the equipment near the football goal can be enhanced, and the work is smoother.
After a three-dimensional model of the venue is built in modeling software, namely position information of the millimeter wave base station, the uplink equipment and the downlink equipment is determined, the three-dimensional coordinate system of the venue can be used for measuring the position information of the uplink equipment and the downlink equipment relative to the millimeter wave base station.
After the azimuth information is determined, a beam-forming instruction can be generated by using an intelligent terminal or an internet of things platform, the instruction can contain the azimuth information and antenna gain parameters, and then the instruction is sent to the millimeter wave base station through a wireless communication technology, so that the millimeter wave base station can send millimeter wave signals according to the azimuth information and the antenna gain parameters in the instruction after receiving the instruction. Among them, wireless communication is a communication method for exchanging information by utilizing the characteristic that an electromagnetic wave signal can propagate in a free space.
In the scheme, the millimeter wave signals are subjected to beam forming according to the direction information of the uplink equipment and the downlink equipment relative to the millimeter wave base station, so that the signals can be sent to a specific direction, the equipment signals corresponding to the direction are enhanced, and the working efficiency is improved. Meanwhile, the energy utilization rate can be improved, and the energy consumption is saved.
In the embodiment of the application, the structure information in a venue is obtained through scanning, and the distribution positions of uplink equipment and downlink equipment in the venue are obtained; constructing a three-dimensional venue model according to the structural information and the distribution positions of the uplink equipment and the downlink equipment; and determining the position information of the millimeter wave base station erected in the venue based on the three-dimensional venue model. By the method for determining the position of the millimeter wave base station in the venue, the position of the millimeter wave base station can be accurately determined, the interference of a shelter on signals of the millimeter wave base station is eliminated, the data transmission speed of the millimeter wave base station in a specific venue is ensured, and the user experience can be improved to a certain extent.

S202, constructing a three-dimensional venue model according to the structural information and the distribution positions of the uplink equipment and the downlink equipment.
And S203, adding a pedestrian interference factor into the three-dimensional venue model according to the structure information in the venue.
The pedestrian interference factor can be the running path of pedestrians in a stadium, a channel for the pedestrians to run in the stadium, and because the signal sent by the millimeter wave base station can be interfered by any shelters, the interference of the pedestrian walking on the signal needs to be considered when the millimeter wave base station is established. Therefore, when the millimeter wave base station is established, the uplink equipment, the downlink equipment and the millimeter wave base station are selected to be established on one side of the pedestrian passageway, so that the problems that signals sent by the millimeter wave base station during operation are blocked by pedestrians, and the uplink equipment and the downlink equipment cannot receive the signals, so that the signals cannot normally work are avoided.
When modeling is carried out by using modeling software, a pedestrian model can be added in a pedestrian passage in the model, and the actual situation of the stadium in normal operation is restored. And after modeling is finished, the model is transmitted to a visualization system to check the three-dimensional model of the venue, so that corresponding adjustment is carried out according to data provided by the visualization system.
And S204, constructing a dynamic simulation model based on the three-dimensional stadium model and the pedestrian interference factor.
The dynamic simulation model can represent the change condition of the state along with time, and in the scheme, the venue dynamic simulation model can reflect the balance relations among all components in the venue and between the venue and the outside and the motion process models of the balance relations.
After the three-dimensional model and the pedestrian interference factors are obtained, a dynamic simulation model of the venue can be constructed using Simulink (visual simulation tool). And then, putting the dynamic simulation model into a visualization system, simulating the actual operation condition of the venue, and determining the placement position of the millimeter wave base station according to the actual operation condition of the venue. After the millimeter wave base station placing position is determined, the coordinate of the millimeter wave base station placing position is determined according to the venue three-dimensional coordinate system, namely the position information of the millimeter wave base station is determined.
S205, determining the position information of the millimeter wave base station erected in the venue according to the dynamic simulation model.
In the embodiment of the application, through increasing the pedestrian interference factor and constructing the dynamic simulation model, the position information of the millimeter wave base station can be determined more accurately, so that the millimeter wave base station can play a role to the greatest extent, and the work efficiency of the millimeter wave base station is improved. Meanwhile, the signal can be prevented from being shielded, and the user experience is improved.
