[0020] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0022] As mentioned in the background technology section, with the development of science and technology and the acceleration of urbanization, people are more and more active in enclosed spaces such as underground facilities and inside buildings. Due to their special structure, these enclosed spaces are often unable to receive traditional satellite signals, resulting in the inability to use functions such as positioning, navigation, and timing. This has caused great inconvenience to the operation management and user experience of underground parking lots, tunnels, subway stations, large shopping malls, airports and other places.

[0023] Existing technologies face many challenges in achieving satellite signal coverage in enclosed spaces. Cost and deployment difficulty are significant issues. Traditional solutions usually require the installation of additional signal enhancement equipment in each enclosed space, which brings complexity to deployment. In addition, in complex electromagnetic environments such as underground or indoors, existing technologies are difficult to ensure the stability and reliability of satellite signals. At the same time, existing technologies are limited in coverage, making it difficult to achieve full coverage of large or complex enclosed spaces, and coverage blind spots often occur. With the continuous emergence of new technologies, the compatibility and scalability of existing technologies are also facing challenges, and they may not be able to adapt to or be compatible with emerging communication standards or equipment in a timely manner.

[0024] In view of this, the present application embodiment proposes a method for using a room distribution system to achieve satellite signal coverage of a closed space, referring to Figure 1 The indoor distributed system includes a satellite gateway, a plurality of branch processors and indoor distributed antenna equipment, and the method includes the following steps:

[0025] Step 101: Use the satellite gateway to acquire a plurality of first satellite signals, and pre-process the plurality of first satellite signals to obtain a plurality of second satellite signals.

[0026] In this step, when satellite signal coverage is required in a closed space, it is first necessary to use a satellite gateway to obtain multiple first satellite signals. The multiple first satellite signals here can come from a satellite signal source device or from an outdoor antenna device. Among them, a closed space refers to an area where satellite signals cannot reach directly, such as underground facilities or inside buildings. The present application is applicable to closed or semi-closed environments such as underground parking lots, tunnels, subway stations, large shopping malls, airports, etc., which are difficult to directly cover with satellite signals due to their special spatial structure. The satellite gateway is adaptable to the branch processor. If the satellite signal comes from a satellite signal source device, the satellite gateway can obtain the satellite signal sent by the satellite signal source device through a ground station. If the satellite signal comes from an outdoor antenna device, the satellite signal can be directly obtained by the satellite gateway. In order to ensure the quality of the first satellite signal, the multiple first satellite signals obtained are pre-processed to obtain multiple second satellite signals, which improves the anti-interference ability and stability of the signal, ensures the signal reliability in a complex electromagnetic environment, and ultimately improves the stability of multiple second satellite signals.

[0027] Step 102, based on the internal layout of the closed space, determine a target branch processor from the multiple branch processors, and use the target branch processor to distribute and process the multiple second satellite signals to obtain multiple target satellite signals.

[0028] In this step, the internal layout of the closed space is not static, and the internal layout of the closed space is determined by the user's predetermined needs. For example, the indoor buildings in the closed space may change, which in turn causes changes in the communication needs in the closed space, which will affect the coverage of the satellite signal in the closed space. For another example, the feeder compatibility and signal coverage requirements in the closed space will also change, which will affect the internal layout of the closed space and affect the coverage of the satellite signal in the closed space. Therefore, it is necessary to determine the target branch processor that needs to process multiple second satellite signals among multiple branch processors based on the internal layout of the closed space. For example, a simple closed space only needs to use the most basic branch processor, while a higher-level branch processor is required for a complex closed space. Multiple second satellite signals are sent to the target branch processor using a satellite gateway. The present application has multiple branch processors, and the target branch processor is selected according to the needs, taking into account the needs of rapid deployment, simplifying the installation process, and improving deployment efficiency. The target splitting processor is used to distribute and process the multiple second satellite signals to obtain multiple target satellite signals, so that the multiple target satellite signals can be diffused, and the diffusion range of the multiple target satellite signals is increased, so that the subsequent multiple target satellite signals can be fully covered in the closed space through the indoor antenna device. It should be noted that the type of the target splitting processor determines whether the multiple target satellite signals are actively sent to the indoor antenna device, or the indoor antenna device actively captures the multiple target satellite signals.

[0029] Step 103: Use the room-based antenna device to transmit the multiple target satellite signals in the closed space, so that the multiple target satellite signals cover the closed space.

[0030] In this step, after completing the above operations, you can start using the indoor antenna equipment to transmit multiple target satellite signals into the enclosed space. In this process, it is necessary to ensure that all indoor antenna equipment can work normally and will not interfere with each other, so as to achieve the best signal coverage effect. The indoor antenna equipment is distributed in the enclosed space, and the indoor antenna equipment can receive or capture the target satellite signals within its working range, so that the target satellite signals can fully cover the enclosed space, thereby improving the accuracy and reliability of positioning, navigation and timing in the enclosed space.

[0031] It should be noted that the specific number of satellite gateways, branch processors and indoor antenna equipment is determined according to the area of ​​the enclosed space and user needs. The indoor system design in this application is forward-looking, can adapt to the development of future technologies, and has good compatibility and scalability. The system of the present invention also supports software upgrades and remote management, has high flexibility and scalability, and can easily cope with new technologies and challenges that may arise in the future. The present application is designed for enclosed spaces such as underground pipe galleries where satellite signals are limited, which not only improves the positioning accuracy and safety of underground spaces, but also has broad application potential. This technology can be easily extended to various indoor places such as underground mines, tunnels, commercial centers, etc., to optimize emergency response and daily operation and maintenance processes. Its flexibility and scalability mean that it can be integrated with a variety of indoor positioning technologies to form a high-precision positioning system, providing strong technical support for the underground space management of smart cities.

[0032] Through the above scheme, the satellite gateway is used to obtain multiple first satellite signals, and the multiple first satellite signals are pre-processed to obtain multiple second satellite signals, thereby improving the stability of the multiple second satellite signals. Based on the internal layout of the closed space, a target branch processor is determined among the multiple branch processors, and the target branch processor is used to distribute and process the multiple second satellite signals to obtain multiple target satellite signals, so that the multiple target satellite signals can be diffused, thereby increasing the diffusion range of the multiple target satellite signals. The multiple target satellite signals are transmitted in the closed space using the room antenna device so that the multiple target satellite signals cover the closed space, so that the target satellite signals can fully cover the closed space.

[0033] In some embodiments, determining a target branch processor from the multiple branch processors based on the internal layout of the closed space includes: determining the complexity of the internal layout based on the internal layout of the closed space; and screening out the target branch processor from the multiple branch processors based on the complexity.

[0034] In this embodiment, the internal layout of the closed space is different, and the complexity of the internal layout is different. When the internal layout is relatively complex, the complexity of the internal layout is relatively high; when the internal layout is relatively simple, the complexity of the internal layout is relatively low. For example, when there are relatively many buildings indoors, the complexity of the internal layout is relatively high; when there are relatively few buildings indoors, the complexity of the internal layout is relatively low. It should be noted that the flow of people can also be regarded as a special internal layout, and the flow of people in the closed space can be predicted based on historical experience. The internal layout determines the communication needs of the closed space, and the internal layout is quantified into complexity by comprehensively considering the factors involved in the internal layout. Based on the complexity, the target branch processor is screened out from multiple branch processors to ensure that the target branch processor can meet the needs of branching multiple target signals.

[0035] In some embodiments, the branch processor includes a first branch processor, a second branch processor and a third branch processor; based on the complexity, screening out the target branch processor from the multiple branch processors includes: in response to determining that the complexity is greater than or equal to a first complexity, determining the first branch processor as the target branch processor; in response to determining that the complexity is less than the first complexity and greater than or equal to a second complexity, determining the second branch processor as the target branch processor; in response to determining that the complexity is less than the second complexity, determining the third branch processor as the target branch processor.

[0036] In this embodiment, the complexity determines which branch processor is selected from multiple branch processors as the target branch processor. When the complexity is greater than or equal to the first complexity, the first branch processor included in the multiple branch processors is used as the target branch processor, and the first branch processor is suitable for a closed space with a relatively complex internal layout because it has a stronger signal diffusion capability. When the complexity is less than the first complexity and greater than or equal to the second complexity, the second branch processor included in the multiple branch processors is used as the target branch processor, and the second branch processor is suitable for a closed space with a medium complexity internal layout, and its signal diffusion capability is weaker than that of the first branch processor. When the complexity is less than the second complexity, the third branch processor included in the multiple branch processors is used as the target branch processor, and the third branch processor is suitable for a closed space with a relatively simple internal layout, and its signal diffusion capability is slightly weaker than that of the second branch processor. Comparing the complexity with the comparison value ensures that the selected target branch processor can meet the needs of branching multiple target signals.

[0037] In some embodiments, the target branch processor is a first branch processor, which includes a first multi-system access platform, a first power divider, a first coupler and a leaky cable; the use of the target branch processor to distribute and process the multiple second satellite signals includes: using the first multi-system access platform to receive the multiple second satellite signals and combining each second satellite signal; using the first power divider to evenly distribute signals of the multiple second satellite signals that have undergone the combining process; using the first coupler to distribute power to the multiple second satellite signals that have undergone the evenly distributed signals; and using the leaky cable to diffuse the multiple second satellite signals that have undergone the power distribution in the closed space.

[0038] In this embodiment, the first branch processor includes a first multi-system access platform, a first power divider, a first coupler and a leaky cable, wherein the first multi-system access platform receives multiple second satellite signals and combines each second satellite signal with a cellular network signal of an existing communication system (such as 4G / 5G). Satellite signals and cellular network signals each have their own unique advantages and limitations. By integrating the two, they can give full play to their respective advantages and make up for each other's shortcomings. The first multi-system access platform can ensure the compatibility of satellite signals. The first multi-system access platform sends multiple second satellite signals that have been combined to the first power divider to perform preliminary signal distribution in a closed space. The first power divider is used to evenly distribute the signals of the multiple second satellite signals that have been combined to ensure that the signals can be evenly distributed to each coverage area in the closed space later. The first power divider is used to send multiple second satellite signals that have been evenly distributed to the first coupler, and the first coupler is used to distribute the power of multiple second satellite signals that have been evenly distributed. The first coupler is allocated according to the power requirements of the signal to meet the needs of different coverage areas. A first coupler is used to send multiple power-distributed second satellite signals to a leaky cable, which is evenly distributed in a closed space. The leaky cable is a special transmission line that can guide electromagnetic waves in its structure to propagate along its length, while allowing the signal to "leak" out at a specific location for use by the receiving device. The leaky cable is used to widely diffuse multiple power-distributed second satellite signals in a closed space. It should be noted that when the indoor antenna device determines that the target branch processor is the first branch processor, the leaky cable widely diffuses the multiple power-distributed second satellite signals in the closed space to obtain multiple target satellite signals, and the indoor antenna device captures the multiple target satellite signals. The present application utilizes a room-based antenna system including a leaky cable to achieve full coverage of the closed space without dead ends or omissions.

[0039] In some embodiments, the target branch processor is a second branch processor, and the second branch processor includes a second multi-system access platform, a second power splitter and a second coupler; the use of the target branch processor to distribute and process the multiple second satellite signals includes: using the second multi-system access platform to receive the multiple second satellite signals and combining each second satellite signal; using the second power splitter to evenly distribute the signals of the multiple second satellite signals that have been combined; and using the second coupler to distribute the power of the multiple second satellite signals that have been evenly distributed.

[0040] In this embodiment, if Figure 2 As shown, the second branch processor includes a second multi-system access platform, a second power divider, and a second coupler, wherein the second multi-system access platform receives multiple second satellite signals and combines each second satellite signal with the cellular network signal of the existing communication system (such as 4G / 5G). Satellite signals and cellular network signals each have their own unique advantages and limitations. The integration of the two can give full play to their respective advantages and make up for the shortcomings of each other. The second multi-system access platform can ensure the compatibility of satellite signals. The second multi-system access platform sends multiple second satellite signals that have been combined to the second power divider to perform preliminary signal distribution in the closed space. The second power divider is used to evenly distribute the signals of the multiple second satellite signals that have been combined to ensure that the signals can be evenly distributed to each coverage area in the closed space later. The second power divider is used to send multiple second satellite signals that have been evenly distributed to the second coupler, and the second coupler is used to distribute the power of multiple second satellite signals that have been evenly distributed. The second coupler is allocated according to the power requirements of the signal to meet the needs of different coverage areas. Since the internal layout complexity corresponding to the second reasonable processor is medium, the signal distribution function of the power divider and the coupler can meet the signal coverage requirements of the closed space by using the multi-system access platform, which not only saves relevant resources but also ensures that the signal can be fully covered in the closed space. It should be noted that when the target branch processor is determined to be the second branch processor by using the target branch processor, the obtained multiple target satellite signals are sent to the indoor antenna device.

[0041] In some embodiments, the target branch processor is a third branch processor, and the third branch processor includes a third power divider and a third coupler; the distribution processing of the multiple second satellite signals using the target branch processor includes: using the third power divider to evenly distribute the multiple second satellite signals and using the third coupler to perform power distribution on the multiple second satellite signals that have been evenly distributed through the signals.

[0042] In this embodiment, the third branch processor includes a third power divider and a third coupler, wherein the third power divider is used to evenly distribute the received multiple second satellite signals to ensure that the signals can be evenly distributed to each coverage area in the closed space later. The third power divider is used to send the multiple second satellite signals that have been evenly distributed to the third coupler, and the third coupler is used to distribute the power of the multiple second satellite signals that have been evenly distributed. The third coupler distributes the signals according to the power requirements to meet the needs of different coverage areas. Since the internal layout complexity corresponding to the third reasonable processor is relatively low, the signal distribution function of the power divider and the coupler can meet the signal coverage requirements of the closed space, which not only saves relevant resources, but also ensures that the signal can be fully covered in the closed space. It should be noted that when the target branch processor is used to determine that the target branch processor is the third branch processor, the obtained multiple target satellite signals are sent to the indoor antenna device. It should also be noted that the first branch processor, the second branch processor and the third branch processor all include power dividers and couplers. When deploying the indoor distributed system, only one set of power dividers and couplers can be deployed, making the indoor distributed system easy to deploy.

[0043] In some embodiments, the preprocessing includes regeneration processing and forwarding processing; the preprocessing of the multiple first satellite signals includes: in response to determining that the first satellite signal is a satellite signal generated by a source device, performing the regeneration processing on the first satellite signal; in response to determining that the first satellite signal is a satellite signal received by an outdoor antenna, performing the forwarding processing on the first satellite signal.

[0044] In this embodiment, a plurality of first satellite signals are preprocessed, and the preprocessing mentioned here may refer to regeneration processing or forwarding processing. For example, when the first satellite signal is directly sent by the satellite signal source device, the first satellite signal at this time is an original signal without any processing, so it needs to be regenerated, that is, the first satellite signal is amplified and sent out again, and the specific regeneration processing includes signal amplification, frequency correction and noise reduction. By regenerating the first satellite signal, the quality and stability of the signal are ensured. When the first satellite signal is received by the outdoor antenna device and then sent to the satellite gateway, the first satellite signal at this time has been amplified to a certain extent, so it only needs to be forwarded. By forwarding the first signal, the signal can be enhanced and the loss during transmission can be reduced. After the outdoor antenna receives the satellite signal, it converts it and retransmits it into the closed space. The source device generates a satellite signal and broadcasts it as a new signal source in the closed space. Acquiring the satellite signal generated by the source device not only improves the flexibility of the system, but also reduces the dependence on the external signal source, so that the indoor positioning function can be realized even in the scenario where the GNSS signal cannot be directly received.

[0045] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0046] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
