[0027] Embodiment 1

[0028] Figure 1 A flowchart of a wireless signal coverage method provided in Example 1 of the present application. This embodiment can be applied to the situation of providing wireless signal coverage for urban rail transit sections. The method can be executed by a wireless signal coverage device, which can be implemented in software and / or hardware and specifically configured in an electronic device, such as a wireless coverage control platform.

[0029] See also Figure 1 The wireless signal coverage method shown specifically includes the following steps:

[0030] S110: Acquire the area environment and antenna receiving direction of the area to be covered.

[0031] The interval to be covered may be an interval that needs to be covered by wireless signals. Exemplarily, the interval to be covered may be a subway interval. The interval environment may be an environment that affects the transmission of wireless signals in the interval to be covered, which is used to determine the radiation parameters of the smart metasurface. Exemplarily, the interval environment may include the wireless signal transmission environment, the interval terrain, and the type of wireless signal. For example, when the wireless signal transmission environment of the interval environment is poor, the radiation intensity of the wireless signal can be increased. For example, when the interval terrain is more complex, the radiation angle can be adjusted to ensure full coverage of the wireless signal in the interval to be covered. For example, when there are many types of wireless signals, signal radiation strategies of various standards can be set to ensure the transmission of wireless signals of various standards.

[0032] The antenna receiving direction may be the antenna receiving direction of the vehicle in the interval to be covered, which is used to determine the radiation parameters of the smart metasurface. The antenna receiving direction may be the roof, the bottom of the vehicle, or the position of a hidden antenna, etc., which is not specifically limited in this application. For example, if the vehicle receiving antenna is installed at the roof position, that is, the antenna receiving direction is in the direction of the roof, then the smart metasurface electromagnetic radiation unit can be adjusted to radiate wireless signals to the top of the vehicle; if the vehicle receiving antenna is installed at the bottom of the vehicle, that is, the antenna receiving direction is in the direction of the bottom of the vehicle, then the smart metasurface electromagnetic radiation unit is dynamically adjusted to radiate wireless signals to the bottom of the vehicle; if the vehicle is a hidden antenna, that is, the antenna receiving direction is in the direction of the hidden antenna, then the smart metasurface electromagnetic radiation unit can be adjusted to radiate wireless signals to the hidden antenna. The radiation direction is determined by the antenna receiving direction, and the scheme is flexible and adjustable, which reduces the space occupied by vehicle equipment in the interval to a certain extent.

[0033] S120. Determine the radiation parameters of the intelligent metasurface according to the section environment and the antenna receiving direction; the intelligent metasurface is installed in the shield segment.

[0034] Reconfigurable Intelligence Surface (RIS) is a metasurface that contains electronically controllable and low-power analog processing elements. It can adjust the absorption, reflection, refraction and phase of passive reflective elements in real time to guide the incident electromagnetic signal to the desired direction.

[0035] Smart metasurfaces can be deployed at different locations on surfaces such as buildings and indoor walls. In subway scenarios, prefabricated shield segments have been widely used in subway underground tunnel sections. When prefabricated shield segments are produced, installation space can be reserved according to the size of the smart metasurface electromagnetic radiation unit. The smart metasurface is installed in the shield segment, which does not occupy the installation space of the interval equipment, saves the installation space resources of the interval equipment, and reduces the risk of equipment infringement.

[0036] The radiation parameters may be related parameters for controlling the reflection and refraction of the intelligent metasurface, and are used to adjust the coverage area of ​​the wireless signal. For example, the radiation parameters may include the radiation direction and the radiation intensity. For example, the radiation direction is determined according to the terrain characteristics and the antenna receiving direction in the interval environment, and the radiation intensity is determined according to the propagation conditions in the interval environment.

[0037] In order to ensure the safe, high-density and efficient operation of urban rail transit, it is necessary to establish a corresponding wireless communication system. The wireless communication system is a safe, reliable and effective communication subsystem that can provide a reliable means of communication for the exchange of voice and data information between fixed users (control centers, vehicle base dispatchers and station attendants, etc.) and mobile users (train drivers, disaster prevention personnel and maintenance personnel). At the same time, when abnormal conditions occur in subway operations and wired communications fail, it can quickly provide wireless communication support required for command such as disaster prevention and rescue and accident handling. The wireless communication system installs wireless signal transmission equipment in the section to cover the entire section with wireless signals, so as to build a wireless network data channel between the vehicle and the ground, and meet the wireless network data transmission requirements between the vehicle and the ground.

[0038] At present, subway sections generally use leaky cables as radiation units to provide wireless signal coverage in the section. Directional antennas are added as supplementary coverage methods under special circumstances. In existing wireless coverage solutions and systems, the radiation equipment of wireless signals in the section has high requirements for installation space. In the face of complex environmental conditions, it is impossible to adaptively adjust the radiation direction and coverage strength of wireless signals. In the face of long sections, the coverage requirements can only be met by adding terminal equipment, and the implementation of the system solution is cumbersome and inflexible.

[0039] The technical solution of this embodiment obtains the interval environment and antenna receiving direction of the interval to be covered; determines the radiation parameters of the intelligent super surface according to the interval environment and antenna receiving direction; based on the editable characteristics of the intelligent super surface, the radiation parameters can be adaptively adjusted in real time according to the interval environment and antenna receiving direction, thereby improving the flexibility of adjusting the wireless signal coverage direction. The intelligent super surface is installed in the shield segment to reduce the requirements for installation space. Therefore, the technical solution of this application solves the problem that the leaky cable and antenna have high requirements for installation space, and the adjustment of the coverage direction of the wireless signal is complex and has poor adaptability, thereby achieving the effect of improving the flexibility and adaptability of adjusting the wireless signal coverage direction and reducing the requirements for installation space.

[0040] Embodiment 2

[0041] Figure 2a This is a flow chart of a wireless signal coverage method provided in Embodiment 2 of the present application. The technical solution of this embodiment is further refined on the basis of the above technical solution.

[0042] Furthermore, when the interval to be covered is the overlapping area of ​​adjacent cells, the "radiation parameters of the intelligent supersurface are determined according to the interval environment and the antenna receiving direction" is refined to: "According to the interval shape of the interval to be covered and the antenna receiving direction, the radiation direction and radiation intensity of the intelligent supersurfaces of two adjacent cells are determined" to realize cross-zone switching of adjacent cells.

[0043] See also Figure 2a A wireless signal coverage method is shown, comprising:

[0044] S210: Acquire the area environment of the area to be covered and the antenna receiving direction.

[0045] S220. Determine the radiation direction and radiation intensity of the intelligent supersurfaces of two adjacent cells according to the interval shape and antenna reception direction of the interval to be covered.

[0046] The radiation area corresponding to each smart metasurface is a cell. The wireless signal areas radiated by two adjacent smart metasurfaces will overlap to a certain extent, that is, there is a situation where the coverage interval is the overlapping area of ​​adjacent cells. At this time, it is necessary to dynamically adjust the radiation parameters of the adjacent cells so that the receiving device can achieve cross-zone switching of wireless signals and ensure full coverage of wireless signals. Figure 2b A schematic diagram of a handover. Figure 2b In the figure, 21 is the smart metasurface, 22 is the radiation area corresponding to the smart metasurface, and 23 is the vehicle traveling from left to right. Figure 2b There is a certain overlap in the radiation areas corresponding to the two adjacent smart metasurfaces. In order to ensure that the vehicle can smoothly achieve inter-zone switching when it drives into the overlapping area of ​​adjacent cells, it is necessary to adaptively adjust the radiation direction and radiation intensity of the two adjacent cell smart metasurfaces so that the vehicle can receive the wireless signal radiated by the right smart metasurface in time after entering the radiation area corresponding to the right smart metasurface.

[0047] When receiving two wireless signals, the receiving device will select one of the wireless signals to connect according to certain rules. For example, when the receiving device receives two wireless signals, it will connect to the wireless signal with greater signal strength. Therefore, when switching across cells, the wireless control system can dynamically adjust the radiation direction and radiation strength of the wireless signals in the overlapping coverage area of ​​the two cells, so that there is a significant signal strength difference in the overlapping coverage area of ​​the two cells, so as to ensure the smooth switching of wireless signals across cells and achieve continuous coverage of wireless signals in the interval.

[0048] In an optional embodiment, the radiation direction and radiation intensity of the intelligent supersurfaces of two adjacent cells are determined according to the interval shape of the interval to be covered and the antenna reception direction, including: if the interval to be covered is a straight segment interval, the radiation intensity of the first cell is reduced, and the radiation direction of the first cell is controlled to shift toward the current cell; if the interval to be covered is a curved segment interval, the radiation intensity of the first cell is reduced, and the radiation direction of the first cell is controlled to shift toward the adjacent cell.

[0049] The first cell can be the cell that the vehicle passes through first in the driving process of two adjacent cells. If the interval to be covered is a straight line interval, the wireless signal strengths of the two cells in the interval to be covered are basically the same, and the radiation directions are opposite. In this case, the wireless control system needs to be used to reduce the signal radiation power of the first cell and adjust the radiation direction to the direction of the cell, thereby reducing the repeated coverage area of ​​the wireless signals of the two cells and ensuring smooth cross-cell switching.

[0050] If the interval to be covered is a curved section, due to the constraints of terrain conditions, the radiation direction of the wireless signals of each cell in the interval to be covered will slightly deviate toward the direction of the cell. In this case, it is necessary to use the wireless control system to adjust the radiation direction of the wireless signal of the first cell toward the adjacent cell, thereby increasing the repeated coverage area and ensuring smooth switching across cells.

[0051] If the interval to be covered is a straight line interval, the radiation intensity of the first cell is reduced, and the radiation direction of the first cell is controlled to shift toward the current cell; if the interval to be covered is a curve segment interval, the radiation intensity of the first cell is reduced, and the radiation direction of the first cell is controlled to shift toward the adjacent cell, thereby ensuring that the radiation parameters are adjusted according to the radiation characteristics in different environments to achieve inter-zone switching of wireless signals.

[0052] In an optional embodiment, if there is a partition wall in the area to be covered, the radiation parameters of the smart metasurface are determined according to the area environment and the antenna reception direction, including: adding a passive relay unit in the partition wall, and determining the radiation direction of the smart metasurface according to the position of the passive relay unit and the antenna reception direction.

[0053] In subway scenarios, there is a complex underground section environment. Due to the needs of driving conditions and the constraints of actual geological conditions, partition walls are set between the driving tracks to ensure the stability of the section structure, but it is easy to cause wireless signal blind spots, affecting the full coverage of wireless signals. In traditional solutions, leaky cables or directional antennas are installed at the partition walls to cover the wireless signals at the partition walls, but the corresponding feeder lines need to be pre-buried under the driving track bed, which requires crossing the track, increasing the difficulty of project implementation.

[0054] The present invention utilizes the reflection characteristics of the intelligent metasurface electromagnetic radiation unit, sets a passive relay unit at the partition wall, adjusts the radiation direction of the wireless signal on the main line section side, covers the wireless signal blind area at the partition wall through the reflection mechanism, and reflects the wireless signal to the antenna receiving direction, so that the vehicle can receive the wireless signal. The passive relay unit is a passive device, and there is no need to place a signal feeder for connection, which reduces the interval wireless signal terminal equipment and cable connection, and reduces the difficulty of project implementation.

[0055] Part of the smart metasurface is a passive metasurface. Therefore, if there is a wall in the area to be covered, a passive relay unit can be added to the wall, that is, the smart metasurface is installed in the wall, and the smart metasurface is controlled to use the passive relay unit to reflect the wireless signal. Specifically, the radiation direction of the smart metasurface is determined according to the position of the passive relay unit and the antenna receiving direction, so that the wireless signal can be reflected to the antenna receiving direction.

[0056] Figure 2c This is a schematic diagram of a passive relay unit reflection. The tunnel wall is the outermost wall, and a partition wall is set in the middle. A signal blind spot may be formed in the middle of the partition wall. Therefore, a passive relay unit is added on the inner side of the partition wall to reflect the wireless signal and achieve full coverage of the wireless signal.

[0057] If there is a wall in the area to be covered, a passive relay unit is added to the wall, and the radiation direction of the smart metasurface is determined according to the position of the passive relay unit and the antenna receiving direction, so as to achieve coverage of wireless signals in the area blocked by the wall. In addition, adding a passive relay unit to the wall can reduce the difficulty of equipment installation.

[0058] The technical solution of this embodiment determines the radiation direction and radiation intensity of the intelligent supersurfaces of two adjacent cells according to the interval shape and antenna receiving direction of the interval to be covered when the interval to be covered is the overlapping area of ​​the adjacent cells, and adjusts the radiation direction and radiation intensity considering different interval shapes and antenna receiving directions to ensure smooth inter-cell switching between adjacent cells and ensure the continuity of wireless signals.

[0059] Embodiment 3

[0060] Figure 3 This is a flow chart of a wireless signal coverage method provided in Example 3 of the present application. The technical solution of this embodiment is further refined on the basis of the above technical solution.

[0061] Furthermore, if the interval environment includes at least two wireless standards, the "radiation parameters of the intelligent metasurface are determined according to the interval environment and the antenna receiving direction" is refined to: "radiation parameters of the intelligent metasurface are determined according to the wireless standard, interval environment and antenna receiving direction" to achieve full coverage of multiple wireless standards.

[0062] See also Figure 3 A wireless signal coverage method is shown, comprising:

[0063] S310: Obtain the area environment and antenna receiving direction of the area to be covered.

[0064] S320. Determine the radiation parameters of the smart metasurface according to the wireless standard, the area environment, and the antenna receiving direction.

[0065] Wireless standards can be wireless signals with different modulation modes and different frequency bands to meet the wireless communication needs of different devices. In the subway main line section, wireless signals with multiple frequency bands such as TETRA (800M) (professional term, a wireless standard), WLAN (2.4G) (professional term, a wireless standard), 4G (professional term, a wireless standard), and 5G (professional term, a wireless standard) may coexist.

[0066] According to the actual application environment and needs, optimization algorithms and wireless signal coverage strategies under different conditions can be established for different wireless standards, and the radiation parameters of the intelligent metasurface can be determined, so that the intelligent metasurface can realize beamforming and multipath propagation, improve the transmission rate and system capacity of wireless signals of different standards, and seamlessly match the network bandwidth requirements of various wireless standards such as TETRA, WLAN, 4G, 5G and 6G (professional term, a wireless standard), realize the smooth evolution and replacement of subway wireless communication systems, and provide wireless network bandwidth guarantee for smart urban rail services with large bandwidth requirements.

[0067] In an optional embodiment, the radiation parameters of the smart metasurface are determined according to the wireless standard, the interval environment and the antenna receiving direction, including: determining the number of electromagnetic radiation units of the corresponding smart metasurface according to the attenuation characteristics of the wireless standard, and determining the radiation intensity and radiation direction of the smart metasurface according to the interval environment and the antenna receiving direction.

[0068] The attenuation characteristic can be the propagation distance of wireless signals of different standards. Wireless signals will attenuate during the propagation process, and their effective coverage range is limited. Therefore, it is necessary to set up multiple smart metasurfaces for radiation to achieve full coverage in the interval. Therefore, in order to ensure full coverage of wireless signals of different standards, the number of radiation units of wireless signals of different standards is different. The radiation parameters of the electromagnetic radiation unit of the smart metasurface are adjusted at intervals so that it is compatible with wireless signals of multiple standards at the same time. For example, the TETRA signal attenuates slowly, and the coverage range corresponding to the same number of smart metasurface electromagnetic radiation units is larger. The number of smart metasurface electromagnetic radiation units of TETRA signals can be reduced to achieve full coverage of interval signals; the WLAN signal attenuates quickly, and the coverage range corresponding to the same number of smart metasurface electromagnetic radiation units is smaller. The smart metasurface electromagnetic radiation units of WLAN signals can be dynamically increased to achieve full coverage of interval signals.

[0069] At the same time, according to the different radiation characteristics of each type of wireless signal, the radiation intensity and radiation direction of the smart metasurface are determined according to the interval environment and the antenna receiving direction, that is, the corresponding wireless signal coverage strategy is set.

[0070] By determining the number of electromagnetic radiation units of the corresponding intelligent metasurface based on the attenuation characteristics of the wireless standard, it is ensured that wireless signals of different standards can achieve full coverage. The radiation intensity and radiation direction of the intelligent metasurface are determined according to the interval environment and the antenna receiving direction. The corresponding radiation intensity and radiation direction are determined based on the radiation characteristics of wireless signals of different standards to ensure compatibility with multiple wireless signals.

[0071] The technical solution of this embodiment is to determine the radiation parameters of the intelligent metasurface according to the wireless standards, the interval environment and the antenna receiving direction when the interval environment includes at least two wireless standards, thereby achieving full coverage of multiple wireless standards, achieving compatibility with wireless signals of multiple wireless standards, and smoothly evolving to be compatible with various wireless standards, thereby meeting the intelligent network bandwidth requirements of the subway.
