[0062] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] The current approach to power conservation for wireless network equipment (wireless devices) in the civilian wireless communications industry is to reduce wireless resource configuration (such as reducing PRB resources and lowering RF power output) when the network is experiencing zero traffic. Otherwise, this will affect users' wireless service usage.

[0064] However, the period of true zero traffic within the coverage area of ​​wireless network equipment is relatively short (typically from 1:00 AM to 5:00 AM). Energy-saving measures are primarily implemented during this period of zero traffic. Energy-saving time periods are highly granular, and some specific scenarios with large numbers of wireless devices have many scattered periods of idle / zero traffic that are not fully utilized for energy conservation. This is primarily due to the industry's lack of a reliable method to identify and predict zero traffic conditions within the coverage area of ​​a specific civilian operator's wireless equipment in real time.

[0065] At the same time, the co-construction and sharing of wireless networks by multiple civil telecommunications operators complicates the feasibility of power-saving solutions for wireless devices. For example, in a city, Civil Telecommunications Operator A builds the 5G network, while Civil Telecommunications Operator B shares it. Based on current technology, Civil Telecommunications Operator A can manually monitor the 5G service status of a specific 5G wireless device in real time through its 5G wireless network management system. If the 5G device is experiencing zero traffic, this does not guarantee that Civil Telecommunications Operator B's 5G service will also be experiencing zero traffic on the same device. If Civil Telecommunications Operator A manually implements device power saving based on its own 5G network management information, it is very likely that 5G users of Civil Telecommunications Operator B, who share the same 5G device, will be unable to use 5G services.

[0066] Given the complexity and feasibility of the aforementioned wireless device power-saving methods, civilian communications operators currently employ deep sleep and symbol shutdown techniques to conserve power for wireless devices in low-load areas of the wireless network at night in the early hours of each morning. However, these energy-saving solutions do not fully exploit the energy-saving potential in special scenarios where a large number of wireless devices are deployed.

[0067] Taking the subway as an example, subway lines are a special scenario where a large number of wireless devices are deployed. In this scenario, to solve the problem of wireless communication in subway tunnels, 2G, 3G, 4G, and 5G wireless network equipment are deployed approximately every 300 to 600 meters in the tunnels. To save energy and reduce consumption, civil communication operators will keep the wireless devices in the subway tunnels in a low-power state for a few hours after the subway line stops operating each day and before normal operation the next day, thereby achieving energy-saving effects.

[0068] However, during normal subway line operation, these wireless devices operate at a preset output power. For each subway line, the tunnel section between two stations is in a zero-traffic state when no trains are passing through it. When a subway train passes through a tunnel section, the wireless devices covering that section provide wireless network services. Before or after the train reaches or leaves the tunnel section, the wireless devices covering that section continue to operate at the preset RF output power, even though they do not need to provide any services. These zero-traffic periods occur periodically in every tunnel section of the subway. During train operation hours, each tunnel section and each train has only about one minute of train traffic, with no trains passing for the remaining three to eight minutes. This means that for each train and each tunnel section, the majority of the time is in a zero-traffic state. However, according to current wireless network energy-saving solutions, the equipment in the tunnel track area still operates at the preset output power during these zero-traffic periods during operation hours, and the energy consumed during these periods does not generate any benefits.

[0069] In view of this, an embodiment of the present invention provides a wireless device energy-saving system, method, electronic device and storage medium. For tunnel sections, before the train arrives at these tunnel sections or after leaving these tunnel sections, the wireless devices in these tunnel sections automatically deactivate the radio frequency channels and other methods to significantly reduce the power consumption of the equipment (enter the energy-saving state), and activate the radio frequency channels in advance before the train is about to arrive at these tunnel sections (exit the energy-saving state) to ensure the normal use of wireless services by train passengers.

[0070] Reference Figure 1, which shows a block diagram of a wireless device energy-saving system provided in an embodiment of the present invention. The wireless device energy-saving system 100 includes a detection subsystem 101, a policy subsystem 102, and a scheduling subsystem 103. The policy subsystem 102 is connected to the detection subsystem 101 and the scheduling subsystem 103, respectively. The scheduling subsystem 103 is connected to the wireless device 201. The wireless device 201 and the detection subsystem 101 are deployed in a train tunnel. The train tunnel consists of several tunnel sections. The wireless device 201 is used to provide wireless network services for the tunnel sections.

[0071] The detection subsystem 101 is used to monitor the position information of the train in the train tunnel and send the position information to the strategy subsystem 102;

[0072] The strategy subsystem 102 is configured to send an energy-saving instruction to the scheduling subsystem 103 when it is determined based on the position information that the train has left the target tunnel section;

[0073] The scheduling subsystem 103 is configured to control the wireless device 201 in the target tunnel section to enter a power-saving state according to the power-saving instruction.

[0074] The detection subsystem is a state detection subsystem responsible for real-time detection and timely reporting of train passing event information (location information). The strategy subsystem is a wireless device energy-saving policy management subsystem responsible for energy-saving policy setting, energy-saving event analysis, and energy-saving status update decisions. The scheduling subsystem is a wireless device energy-saving status scheduling subsystem responsible for executing energy-saving status update instructions.

[0075] Wireless devices can be 2G, 3G, 4G, or 5G. Civilian telecommunications operators will centrally install wireless devices at intervals (generally 300 to 600 meters) within the tunnel track area in both directions of travel of each train tunnel. Wireless signals from these devices will be transmitted through wireless signal transmission media such as leaky cables deployed along the tunnel section to provide wireless network services along the train route.

[0076] The train tunnel can be a subway tunnel, but the embodiments of the present invention are not limited to this. For example, the train tunnel can also be a train tunnel. There are two train track deployment schemes within a train tunnel. The first is to deploy the tracks for the up and down directions in two isolated, independent tunnels, and the second is to deploy the tracks for both directions in the same tunnel. For example, the current deployment scheme for domestic subway lines mainly focuses on the first scheme. The technical solution described in the embodiments of the present invention is based on the first subway train track deployment scheme, but it can also be applied to the second subway train track deployment scheme, and the embodiments of the present invention are not limited to this.

[0077] Specifically, the detection subsystem is deployed in a train tunnel. During train operation, the detection subsystem monitors the train's position in the tunnel and transmits this information to the policy subsystem. Based on the train's position information, the policy subsystem determines that the train has left the target tunnel section, indicating that the target tunnel section is in a zero-traffic state. Therefore, the policy subsystem transmits an energy-saving instruction to the scheduling subsystem, which controls the wireless devices in the target tunnel section to enter an energy-saving state based on the energy-saving instruction. For example, the scheduling subsystem can directly control the energy-saving / non-energy-saving state of the wireless devices. Alternatively, a dedicated management device can be used to manage the wireless devices in the target tunnel section, adjusting the state of the wireless devices in the target tunnel section to an energy-saving state or a non-energy-saving state. For example, upon receiving the energy-saving instruction, the scheduling subsystem transmits a state update instruction for the wireless devices to the management device, which then adjusts the wireless devices in the target tunnel section to an energy-saving state. The embodiments of the present invention are not limited to the manner in which the scheduling subsystem controls the wireless devices in the target tunnel section to enter an energy-saving state based on the energy-saving instruction.

[0078] In this embodiment of the present invention, during train operation, the detection subsystem detects the train's position in a tunnel and transmits this information to the strategy subsystem. Upon determining, based on this position information, that the train has left a target tunnel section, the strategy subsystem transmits an energy-saving instruction to the dispatch subsystem. The dispatch subsystem then controls the wireless devices in the target tunnel section to enter an energy-saving state based on the energy-saving instruction. In this embodiment of the present invention, during the operating hours of the train line, when a train leaves a target tunnel section and determines that the target tunnel section is within a zero-traffic time period, the wireless devices in the target tunnel section are automatically controlled to enter a low-energy energy-saving state. This increases the duration of wireless devices' energy-saving throughout the day, reduces their power consumption, and avoids resource waste.

[0079] A detection subsystem is used to obtain the train's position information in real time, determine the train's departure from the target tunnel section based on the position information, and then determine that the target tunnel section is in a zero-traffic state. Even in a scenario where multiple civil communication operators jointly build and share wireless equipment, the target tunnel sections and times where multiple civil communication operators simultaneously enter a zero-traffic state in the train tunnel can still be accurately and dynamically determined in real time, making the energy-saving method in the embodiment of the present invention applicable to the wireless equipment of multiple civil communication operators in the train tunnel.

[0080] In one embodiment of the present invention, the train tunnel is divided into several tunnel sections by platforms, the rear end of the target tunnel section is connected to the entrance end of the first platform, and the train leaves the target tunnel section through the first platform; the detection subsystem includes a first detection subsystem and a second detection subsystem, the first detection subsystem is deployed at the entrance end of the first platform, and the second detection subsystem is deployed at the exit end of the first platform; the first detection subsystem is used to send first information data representing the passing status of the train to the strategy subsystem when monitoring the train passing through the entrance end of the first platform; the second detection subsystem is used to send second information data representing the passing status of the train to the strategy subsystem when monitoring the train passing through the exit end of the first platform; the strategy subsystem is used to determine that the train leaves the target tunnel section when obtaining the first information data and the second information data, so as to send the energy-saving instruction to the scheduling subsystem.

[0081] The first information data, the second information data, and the third information data to be described later are train passing events of the train passing detection subsystem, which may include the position and time of the train passing.

[0082] The detection subsystem can be deployed within the platform or within the tunnel section, depending on the specific situation and is not limited in the embodiments of the present invention. As an example, the first detection subsystem and the second detection subsystem are deployed at the entrance and exit of the first platform. The first detection subsystem can be deployed within the first platform near the target tunnel section, and the second detection subsystem can be deployed within the first platform away from the target tunnel section; or the first detection subsystem can be deployed within the target tunnel section near the first platform, and the second detection subsystem can be deployed within the tunnel section next to the target tunnel section near the first platform.

[0083] The distance between the first detection subsystem and the second detection subsystem deployed at the entrance and exit ends of the first platform is greater than the length of the train, and the train usually stays at the platform for a certain period of time to allow passengers to enter or exit the station. Therefore, when the train passes through the first platform, it passes through the first detection subsystem and the second detection subsystem separately, and does not pass through the first detection subsystem and the second detection subsystem at the same time.

[0084] Specifically, the back end of the target tunnel section is connected to the entrance of the first platform. The first detection subsystem and the second detection subsystem are deployed at the entrance and exit of the first platform, respectively. When a train leaves the target tunnel section, it will inevitably pass through the first platform. Therefore, the first detection subsystem deployed at the entrance of the first platform and the second detection subsystem deployed at the exit of the first platform monitor the train to see if it passes through the first platform. When the first detection subsystem detects a train passing through the entrance of the first platform, it sends first information data indicating the train's passage status to the policy subsystem. When the second detection subsystem detects a train passing through the exit of the first platform, it sends second information data indicating the train's passage status to the policy subsystem. When the policy subsystem continuously obtains the first and second information data over a period of time, it indicates that the train has passed through the first platform and left the target tunnel section. Therefore, a power-saving instruction is sent to the scheduling subsystem, which controls the wireless devices in the target tunnel section to enter a power-saving state through the scheduling subsystem.

[0085] In an embodiment of the present invention, the strategy subsystem confirms that the train has left the target tunnel section only when it receives the first information data and the second information data sent by the first detection subsystem and the second detection system, and then commands the wireless devices in the target tunnel section to enter the energy-saving state, so as to avoid the situation where one of the detection subsystems is falsely triggered, resulting in the wireless devices in the target tunnel section being controlled to enter the energy-saving state when a train exists in the target tunnel section, causing passengers to be unable to use the wireless network service normally.

[0086] It should be noted that the normal use of passenger wireless network services is the bottom line. If one of the two detection subsystems deployed at the entrance and exit ends of the first platform fails to successfully report the train passing event, the wireless devices in the target tunnel section will remain in a non-energy-saving state to ensure the normal use of passenger wireless network services.

[0087] In one embodiment of the present invention, the strategy subsystem is further used to send a recovery instruction to the scheduling subsystem when it is determined based on the position information that the train is about to enter the target tunnel section; the scheduling subsystem is also used to control the wireless devices in the target tunnel section to exit the energy-saving state according to the recovery instruction.

[0088] Specifically, during the operation of the train, the detection subsystem monitors the position information of the train in the train tunnel and sends the train's position information to the strategy subsystem. If the strategy subsystem determines that the train is about to enter the target tunnel section based on the train's position information, indicating that the target tunnel section has left the zero-traffic state, a recovery instruction will be sent to the scheduling subsystem. The scheduling subsystem controls the wireless devices in the target tunnel section to exit the energy-saving state in advance according to the recovery instruction to ensure the normal use of passengers' wireless network services.

[0089] As an example, refer to Figure 2 , one of the schematic diagrams of the wireless device energy saving process provided in the embodiments of the present application is shown. When subway train 3 is in tunnel section B, the wireless device state of tunnel section B is in the non-energy saving state, and the wireless device states of tunnel section A and tunnel section C are in the energy saving state. When the detection subsystem detects that subway train 3 enters station 8, it indicates that subway train 3 is about to enter tunnel section A. Therefore, the wireless device state of tunnel section A is adjusted to the non-energy saving state, and the wireless device state of tunnel section B is adjusted to the energy saving state. Refer to Figure 3 , the second schematic diagram of the wireless device energy saving process provided in the embodiments of the present application is shown. In the same direction, as the next train (for example, train 4) travels forward, when the detection subsystem detects that subway train 4 is about to enter tunnel section C, the wireless device state of tunnel section C is adjusted from the energy saving state to the non-energy saving state to ensure the use of wireless network services by passengers.

[0090] In the embodiments of the present application, the detection subsystem detects the location of the train in real time, so that the wireless device of the target tunnel section where the train is located normally provides wireless network services, while the wireless devices of other target tunnel sections where there is no train implement energy saving operations. Following the travel of different trains, the wireless devices along the way can automatically enter and exit the "energy saving" state in time, thereby increasing the length of time for which the wireless devices are in energy saving throughout the day, reducing the power consumption of the wireless devices, and avoiding waste of resources.

[0091] The detection subsystem detects the location information of the train in real time, and there are multiple ways to determine that the train is about to enter the target tunnel section, as follows:

[0092] In one embodiment of the present invention, the front end of the target tunnel section is connected to the exit of the second platform, the rear end of the previous tunnel section of the target tunnel section is connected to the entrance of the second platform, the front end of the previous tunnel section is connected to the exit of the third platform, the train enters the previous tunnel section through the third platform, leaves the previous tunnel section through the second platform, and enters the target tunnel section; the detection subsystem includes a third detection subsystem and a fourth detection subsystem, the third detection subsystem is deployed at the entrance of the third platform, and the fourth detection subsystem is deployed at the exit of the third platform. the exit end of the third platform; the third detection subsystem is used to send the third information data representing the passing status of the train to the strategy subsystem when it detects that the train passes through the entrance end of the third platform; the fourth detection subsystem is used to send the fourth information data representing the passing status of the train to the strategy subsystem when it detects that the train passes through the exit end of the third platform; the strategy subsystem is used to determine that the train is about to enter the target tunnel section when obtaining the third information data and the fourth information data, so as to send the recovery instruction to the scheduling subsystem.

[0093] Specifically, the front end of the target tunnel section is connected to the exit end of the second platform, the rear end of the previous tunnel section of the target tunnel section is connected to the entrance end of the second platform, and the front end of the previous tunnel section is connected to the exit end of the third platform. The train enters the previous tunnel section through the third platform, leaves the previous tunnel section through the second platform, and enters the target tunnel section. Therefore, when the train passes through the third platform and just enters the previous tunnel section, it indicates that the train is about to pass through the second platform to enter the target tunnel section. Therefore, it is possible to determine whether the train is about to enter the target tunnel section by detecting whether the train passes through the third platform.

[0094] The third and fourth detection subsystems are deployed at the entrance and exit of the third platform. When the third detection subsystem detects a train passing through the entrance of the third platform, it sends third information data indicating the train's passage status to the policy subsystem. When the fourth detection subsystem detects a train passing through the exit of the third platform, it sends fourth information data indicating the train's passage status to the policy subsystem. If the policy subsystem continuously receives the third and fourth information data over a period of time, it indicates that the train has passed through the third platform, entered the previous tunnel section, and is about to enter the target tunnel section. Therefore, a recovery instruction is sent to the dispatch subsystem, which controls the wireless devices in the target tunnel section to exit the energy-saving state before the train enters the target tunnel, ensuring the normal use of wireless network services for passengers.

[0095] In another embodiment of the present invention, the front end of the target tunnel section is connected to the exit of the second platform, the rear end of the upper tunnel section of the target tunnel section is connected to the entrance of the second platform, and the train leaves the upper tunnel section through the second platform and enters the target tunnel section; the detection subsystem includes a third detection subsystem and a fourth detection subsystem, the third detection subsystem is deployed in the upper tunnel section and is separated from the entrance of the second station at a preset distance, and the fourth detection subsystem is deployed at the entrance of the second station; wherein the preset distance is greater than the the length of the train; the third detection subsystem is used to send the third information data representing the passing status of the train to the strategy subsystem when the train is detected to have passed through the third detection subsystem; the fourth detection subsystem is used to send the fourth information data representing the passing status of the train to the strategy subsystem when the train is detected to have passed through the entrance of the second platform; the strategy subsystem is used to determine that the train is about to enter the target tunnel section when the third information data and the fourth information data are obtained, so as to send the recovery instruction to the scheduling subsystem.

[0096] It should be noted that since the train enters the target tunnel section as soon as it passes the second platform, it is not possible to deploy the detection subsystem at the entrance and exit of the second platform to monitor whether the train passes the second platform to determine whether the train is about to enter the target tunnel section. Therefore, in this embodiment of the present invention, the train can be determined to be about to enter the target tunnel section by monitoring whether the train passes through a section in front of the second platform.

[0097] Specifically, the third detection subsystem is deployed in the upper tunnel section and is separated from the entrance of the second station at a preset distance, and the preset distance is greater than the length of the train. The fourth detection subsystem is deployed at the entrance of the second station. When the fourth detection subsystem detects the passing of the train, it indicates that the train has just entered the second platform, has not entered the target tunnel section, and is about to enter the target tunnel section.

[0098] When the third detection subsystem detects that a train has passed through the previous tunnel section and is a preset distance from the second station's entrance, it sends third information data indicating the train's passage status to the strategy subsystem. When the fourth detection subsystem detects that a train has passed through the second platform's entrance, it sends fourth information data indicating the train's passage status to the strategy subsystem. If the strategy subsystem continuously acquires the third and fourth information data within a certain period of time, indicating that the train has passed through the area before the second platform and entered the second platform, and is about to enter the target tunnel section, a recovery instruction is sent to the dispatch subsystem, which controls the wireless devices in the target tunnel section to exit the energy-saving state before the train enters the target tunnel, thereby ensuring the normal use of wireless network services for passengers.

[0099] It should be noted that, in addition to being deployed at the locations described above, the detection subsystem may also be deployed at other locations within the train tunnel, and the specific configuration may be based on actual conditions, which is not limited in the embodiments of the present invention.

[0100] In one example of the present invention, detection subsystems are deployed at both the entrance and exit ends of the terminal platform in the direction of train travel, such as deploying a first detection subsystem at the entrance end of the terminal platform, and deploying a second detection subsystem at the exit end of the terminal platform, so as to determine whether the train has left the tunnel section connected to the terminal platform and the next platform on the terminal platform (the platform in the opposite direction of the train's travel) through the train passing status monitored by the first detection subsystem and the second detection subsystem.

[0101] Usually after the train arrives at the terminal station, the passengers get off, and the train continues to move forward. After passing through a short tunnel, it drives to the turning yard on the ground. In the turning yard, the rear end of the original train becomes the front end, and after changing tracks, it drives in the opposite direction and enters another tunnel. The first station platform after entering another tunnel is the starting station at the same location as the above-mentioned terminal station.

[0102] In one embodiment of the present invention, detection subsystems are deployed at both the entrance and exit ends of the starting station in the train's direction of travel. For example, a first detection subsystem is deployed at the entrance end of the starting platform, and a second detection subsystem is deployed at the exit end of the starting platform. When a train enters the starting station from another tunnel terminal station through the return yard, the train's passing status monitored by the first and second detection subsystems is used to determine whether the train has left the starting station and entered the tunnel section connecting the starting station and the next platform (the platform ahead in the train's direction of travel). Because this first detection subsystem is the first detection subsystem in the train's direction of travel, the interval between the train passing the first detection subsystem and entering the starting station and the next platform is relatively short. To ensure 5G network service within the tunnel section connecting the starting station and the next platform (the platform ahead in the train's direction of travel), the wireless devices within the tunnel section connecting the starting station and the next platform (the platform ahead in the train's direction of travel) are maintained in normal use.

[0103] In one embodiment of the present invention, the scheduling subsystem is configured to control the wireless devices in the target tunnel section to exit the energy-saving state according to the recovery instruction after receiving the recovery instruction sent by the policy subsystem within a preset time.

[0104] Specifically, when it is determined that the train is about to enter the target tunnel section, there may still be a relatively long time before entering the target tunnel section. Therefore, after the scheduling subsystem receives the recovery instruction sent by the strategy subsystem, it is not necessary to immediately control the wireless devices in the target tunnel section to exit the energy-saving state. Instead, it waits for a preset time, and only controls the wireless devices in the target tunnel section to exit the energy-saving state when the train is about to enter the critical time value of the target tunnel section, thereby increasing the length of time that the wireless devices remain in the energy-saving state. Among them, the preset time can be calculated based on the speed of the train and the distance between the train and the front end of the target tunnel section when it is determined that the train is about to enter the target tunnel section. Of course, it can also be calculated in other ways, and the embodiment of the present invention is not limited to this.

[0105] In one embodiment of the present invention, the detection subsystem includes a train passing state sensing module and a communication module; the train passing state sensing module is used to monitor whether a train passes to determine the location information of the train; the communication module is used to send the location information to the strategy subsystem; the strategy subsystem includes a communication interface integration module and a function management integration module; the communication interface integration module of the strategy subsystem is used to receive the location information sent by the detection subsystem and send the energy-saving instruction or the recovery instruction to the scheduling subsystem; the function management integration module is used to determine, based on the location information, that the train is about to enter or leave the target tunnel section, so as to issue the energy-saving instruction for saving energy or the recovery instruction for exiting energy saving to the wireless devices in the target tunnel section; the scheduling subsystem includes a communication interface integration module and a state update execution module; the communication interface integration module of the scheduling subsystem is used to receive the energy-saving instruction or the recovery instruction sent by the strategy subsystem; the state update execution module is used to control the wireless devices in the target tunnel section to enter or exit the energy-saving state according to the energy-saving instruction or the recovery instruction.

[0106] Reference Figure 4 , which shows a structural block diagram of another wireless device energy-saving system provided in an embodiment of the present invention. The wireless device energy-saving system 400 includes a detection subsystem 410, a policy subsystem 420, a scheduling subsystem 430, and an operation and maintenance platform 440.

[0107] The detection subsystem 410 includes a power supply module 411, a communication module 413, and a train passing state sensing module 412 (hereinafter referred to as "sensing module 412"). The detection subsystem 410 is deployed in the subway tunnel track area. Among them:

[0108] 1) Power module 411 contains "-48V DC power module", "POE power module 411", network cable, power cable, responsible for detecting the power supply of subsystem 410. -48V DC power supply can be used to directly power the detection subsystem 410, or -48V DC power supply or 220 AC power supply can be converted into network cable based DC power supply to power the detection subsystem 410.

[0109] 2) Communication module 413 contains a plurality of wireless frequency band programmable radio frequency module, responsible for wireless transmission of information data between detection subsystem 410 and strategy subsystem 420. In the uplink transmission wireless signal frequency band, communication module 413 sends information data (position information) representing train passing state to strategy subsystem 420; in the downlink transmission wireless signal frequency band, receive control information sent by strategy subsystem 420 and execute, including uplink wireless channel transmit power, uplink wireless channel sending period, etc.

[0110] 3) Sensing module 412 contains sensors for sensing whether there is a train passing, data storage of train passing event. This module periodically senses whether there is a train passing in real time, stores the information data of train passing event and time in time, so that communication module 413 can send it to strategy subsystem 420. At the same time, the storage data of sensing module 412 can also be queried through strategy subsystem 420.

[0111] The sampling period of sensing module 412 in detection subsystem 410 can be reasonably configured according to the highest designed speed of each line. For example, the highest designed speed of domestic subway is generally 80km / h, the total length of subway car is 120m, and the time of train passing sensing module 412 at the highest speed is 120÷(80000÷3600)=5.4s. Therefore, the sampling period of sensing module 412 is recommended to be not more than 1.8s, so that even if the train passes through sensing module 412 at the highest speed, sensing module 412 can detect at least 2 train passing events when the train passes through.

[0112] Strategy subsystem 420 contains communication interface integrated module 421, function management integrated module 422. Strategy subsystem 420 is deployed on a server. Among them:

[0113] 1) Communication interface integrated module 421 contains information transmission communication interface between communication module 413 of detection subsystem 410, information transmission communication interface between dispatching subsystem 430, communication interface between operation and maintenance platform 440.

[0114] 2) Functional management integration module 422 includes a wireless device group management module and an energy-saving policy management module. The wireless device group management module groups wireless devices covering different tunnel sections into different device groups, with each wireless device in each group implementing the same energy-saving policy. The energy-saving policy management module configures appropriate energy-saving policies for different device groups and remotely optimizes and adjusts them in real time. It also stores, analyzes, and determines information data related to train passage events, issuing instructions to enable or disable energy-saving for wireless devices within a target wireless device group.

[0115] The scheduling subsystem 430 includes a communication interface integration module 431, an energy-saving state storage module 432, and a state update execution module 433. The scheduling subsystem 430 is deployed on a server and can be deployed in conjunction with the policy subsystem 420 on hardware.

[0116] 1) The communication interface integration module 431 includes a communication interface with the policy subsystem 420 and a communication interface with wireless device professional network management systems such as the wireless professional network management 510 .

[0117] 2) The energy-saving status storage module 432 includes the storage and query of energy consumption status data of each wireless device in all wireless device groups at different times (whether each device is in energy-saving state, energy-saving scheme of each device, RF power value of each device at a specified sampling time point, etc.).

[0118] 3) The state update execution module 433 is responsible for receiving the energy-saving state update command from the policy subsystem 420, issuing an instruction to execute the "enter energy-saving state" or "exit energy-saving state" script to each device in the target wireless device group, and recording the time when the energy-saving state update command is received and the script execution instruction is issued.

[0119] The operation and maintenance platform 440 is used to query the information data of each subsystem and configure the operating parameters of each subsystem.

[0120] Reference Figure 5 , showing a flowchart of the steps of wireless device energy saving provided by an embodiment of the present invention. The process of wireless device energy saving system realizing energy saving of wireless network devices in tunnel track area is described as follows:

[0121] 1) The energy-saving system's detection subsystem's sensing module periodically detects the presence of a train. Whenever a train passes by, the module transmits the detected train passing event data (location information) to the strategy subsystem via the communication module. For example, the communication module transmits this information data via a 4G network.

[0122] 2) The strategy subsystem's communication interface integration module receives the "train passing event information data" from the detection subsystem and submits it to the function management integration module for analysis. The function management integration module combines the current and previous "train passing event information data" to preliminarily determine whether the device groups in the tunnel section the train has exited and the tunnel section the train is about to pass can enter or exit the energy-saving state, respectively. Next, the function management integration module reads the energy-saving status of each wireless device in the target device group from the energy-saving state storage module of the scheduling subsystem through the communication interface integration communication module, verifies the status, and confirms that the current status is "non-energy-saving state" and "energy-saving state," respectively. Finally, the function management integration module determines that the target device group can execute the "enter energy-saving state" and "exit energy-saving state" operations, respectively, and sends the command to the status update execution module of the scheduling subsystem to execute the operations.

[0123] 3) Based on the received energy-saving state update command from the policy subsystem, the state update execution module of the scheduling subsystem selects an appropriate parameter configuration script and notifies the wireless professional network administrator via the integrated interface communication module to execute the "enter energy-saving state" or "exit energy-saving state" operation on the target wireless device. Five seconds after the execution instruction is issued (this time should be appropriately set based on the maximum execution time of the wireless device parameter configuration script), the state update execution module notifies the wireless professional network administrator via the integrated interface communication module to query the target wireless device for the script execution completion status. After confirming that all executions are complete, it notifies the energy-saving state storage module to update the energy-saving state information of the target device group and notifies the policy subsystem's function management integration module of the completion of the energy-saving state update command.

[0124] The detection subsystem is deployed in a tunnel, where the physical environment is relatively harsh and the wireless environment is relatively unstable. At the same time, the energy-saving system needs to exchange data with wireless professional network managers from different wireless equipment manufacturers. The method of the present invention proposes a "quadruple guarantee mechanism" to ensure the timeliness and stability of the energy-saving status update of the target device group and guarantee the reliability of the energy-saving effect.

[0125] 1. The sensing module adopts at least two sensing technologies: The detection subsystem may include at least two different sensors, and adopt at least two different sensing technologies to timely detect the passing of trains, such as sound decibel sensing, light reflection sensing, etc. As long as one of the sensing technologies detects the passage of a train, the information data of the train passing event will be reported, ensuring that even if one sensor fails or malfunctions, the passing of a train can still be detected.

[0126] Second, data reporting via two civilian telecom operators: For example, the communication module in the detection subsystem simultaneously uses the 4G networks of two civilian telecom operators within the tunnel to report train passing events. During the train's passage, all event counts collected by the sensing module are reported to the strategy subsystem. The strategy subsystem only needs to receive two data reports from one of the 4G networks within six seconds. It should be noted that the wireless devices corresponding to the networks used for data reporting remain in normal use and are not switched to a power-saving state.

[0127] 3. Comparison and confirmation of data reported by the two detection subsystems: After the strategy subsystem receives a train passing event report from the detection subsystem deployed at the exit of a station platform, it confirms that it has also received a train passing event report from the detection subsystem deployed at the entrance of the same station platform. It then commands the wireless device group within the tunnel section connected to the station platform, which is opposite to the train's direction of travel, to enter a power-saving state. The normal operation of the passenger wireless network service is paramount. If either of the two detection subsystems deployed before and after the station entrance fails to successfully report a train passing event, the targeted wireless device group remains in a non-power-saving state to ensure the normal operation of the subway passenger wireless network service.

[0128] 4. Reconfirm the energy-saving status update result: After the scheduling subsystem issues an energy-saving status update operation instruction to the wireless professional network manager to execute the target wireless device group, it will query the wireless professional network manager about the current status of the target wireless device group after a reasonable period of time to verify whether the target wireless device group has reached the expected status. If it is not the expected status, the update operation instruction will be issued again until the queried current status is consistent with the expected status.

[0129] In order to better understand the embodiments of the present invention, the following will be explained by taking the process of all 5G wireless devices in a 5G wireless device group covering a certain tunnel section entering and exiting the energy-saving state as an example.

[0130] There are four consecutive tunnel sections along the current subway train's travel direction: L(m-1), Lm, L(m+1), and L(m+2). The train travels from L(m-1) to Lm, then to L(m+1), and finally to L(m+2). The wireless device groups providing wireless signal service for these four tunnel sections are G(m-1), Gm, G(m+1), and G(m+2). Gm includes all wireless devices covering the Lm section, and the same applies to G(m-1), G(m+1), and G(m+2). The subway station platforms between L(m-1) and Lm, between Lm and L(m+1), and between L(m+1) and L(m+2) are S(m-1)m, Sm(m+1), and S(m+1)(m+2).

[0131] A detection subsystem is deployed in the subway tunnel closest to the station, both before and after entering platform Sm(m+1). These subsystems periodically collect data on train passing events. The detection subsystem deployed before entering the Sm(m+1) tunnel (at the entrance end of platform Sm(m+1)) is called SENm(m+1)f (abbreviated as sensor m(m+1)front), and the detection subsystem deployed after exiting the Sm(m+1) tunnel (at the exit end of platform Sm(m+1)) is called SENm(m+1)b (abbreviated as sensor m(m+1)back). Similarly, detection subsystems are deployed before entering and after exiting other stations.

[0132] All wireless devices in the device group G(m+1) covering the tunnel segment L(m+1) enter the energy-saving state as follows:

[0133] 1) At two consecutive sampling times, the detection subsystem SEN(m+1)(m+2)f senses the passage of a subway train. Subsequently, the detection subsystem SEN(m+1)(m+2)b also senses the passage of a subway train at two consecutive sampling times. Both SEN(m+1)(m+2)f and SEN(m+1)(m+2)b send the train passage event data to the strategy subsystem in real time. The two train passage events of SEN(m+1)(m+2)f are referred to as E(m+1)(m+2)f1 and E(m+1)(m+2)f2, respectively. The two train passage events of SEN(m+1)(m+2)b are referred to as E(m+1)(m+2)b1 and E(m+1)(m+2)b2, respectively.

[0134] 2) After receiving E(m+1)(m+2)b1 and E(m+1)(m+2)b2, the strategy subsystem queries whether there is event information data E(m+1)(m+2)f1 and E(m+1)(m+2)f2 within a specific time period (the time period is determined based on the time period with the most frequent subway train schedules). When the query result is "yes", the strategy subsystem determines that the train has left the interval L(m+1) and can implement energy saving for the wireless devices contained in G(m+1). The strategy subsystem sends an instruction to the scheduling subsystem, requiring the wireless devices in the G(m+1) group to enter the energy saving state.

[0135] 3) The scheduling subsystem sends instructions to the wireless professional network manager through the communication interface, and the wireless professional network manager executes the energy-saving solution script for the wireless devices in the G(m+1) group.

[0136] All wireless devices in the 5G wireless device group G(m+1) covering the tunnel segment L(m+1) exit the energy-saving state as follows:

[0137] 1) In 2 consecutive sampling time, the detection subsystem SEN(m-1)mf all senses the subway train passing, then the detection subsystem SEN(m-1)mb also senses the train passing in 2 consecutive sampling time, SEN(m-1)mf and SEN(m-1)mb all send the train passing event information data to the strategy subsystem in real time. The two train passing events of SEN(m-1)mf are respectively referred to as E(m-1)mf1, E(m-1)mf2, and the two train passing events of SEN(m-1)mb are respectively referred to as E(m-1)mb1, E(m-1)mb2.

[0138] 2) After receiving E(m-1)mb1, E(m-1)mb2, the strategy subsystem queries whether there are event information data E(m-1)mf1, E(m-1)mf2 in a specific time period (the time period is determined according to the densest time period of subway train scheduling). When the query result is "yes", the strategy subsystem judges that the train has been in the interval segment Lm and will arrive at the interval segment L(m+1) later, and can require the wireless devices contained in G(m+1) to exit the energy-saving state in advance.

[0139] The dispatching subsystem sends instructions to the wireless professional network management through the communication interface, the wireless professional network management executes the end energy-saving state script for the wireless devices in the G(m+1) group, enters the normal working state, and provides wireless communication services for passengers on the train passing by.

[0140] In the embodiment of the application, the detection subsystem is used to detect the position of the train in real time, so that the wireless devices in the target tunnel interval where the train is located can normally provide wireless network services, and the wireless devices in other target tunnel intervals where there is no train can implement energy-saving operation. Following the driving of different trains, the wireless devices along the route can automatically enter and exit the "energy-saving" state in time, thereby increasing the time length of energy-saving of the wireless devices throughout the day, reducing the power consumption of the wireless devices, and avoiding waste of resources.

[0141] The detection subsystem is used to acquire the position information of the train in real time, and the position information is used to determine that the train leaves the target tunnel section, and then determine that the target tunnel section is in the business zero-flow state. Even in the scenario of multiple private communication operators co-construction and co-wireless equipment, the target tunnel section and time when multiple private communication operators in the train tunnel are in the business zero-flow state can be accurately and dynamically determined in real time. Therefore, for a tunnel line, only one set of wireless equipment energy saving system is deployed, and multiple private communication operators providing wireless coverage for the tunnel line can share the real-time information data of the wireless equipment energy saving system to implement energy saving operation on their own multiple wireless networks. The real-time information data of the wireless equipment energy saving system is unique, and different private communication operators can formulate different energy saving strategies for different wireless networks according to their own needs by using the data.

[0142] The wireless network energy saving scheme currently used in the industry is implemented during the non-operation period of the subway line. The energy saving scheme in the embodiment of the present application can implement energy saving operation during the operation period of the line, and does not affect the wireless service perception of passengers;

[0143] During the non-early morning time, the current industry makes a prediction of the target area without users or business zero-flow, which is mainly based on the signaling interaction between the personal mobile communication terminal and the wireless communication equipment. Since there are many brands and models of personal mobile communication terminals, some terminals may have signaling missing or other problems when performing signaling interaction, thereby reducing the accuracy of the prediction. The energy saving scheme in the embodiment of the present application does not depend on the signaling interaction between the personal mobile communication terminal and the wireless communication equipment. The detection subsystem detects the position information of the train in real time, and accurately predicts the appearance / disappearance time and appearance / disappearance section of the business zero-flow according to the position information of the train in real time, so that the wireless equipment along the train tunnel accurately and timely enters / exits the "energy saving" state.

[0144] When the wireless equipment in the tunnel section enters the energy saving state, the internal same frequency interference on the wireless network in the subway platform can be reduced, and the business perception of passengers waiting on the platform can be improved.
