[0030] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0031] Before introducing the technical solution provided by the embodiment of the present disclosure, an example description of the application scenario can be given first. The technical solution provided by the embodiment of the present disclosure can be applied in the scenario of determining the wireless signal strength corresponding to any indoor location. For example, the 5G signal strength of each location in a certain indoor area can be determined. It should be noted that the technical solution provided by the embodiment of the present disclosure can be executed based on the mobile terminal to determine the wireless signal strength. During the execution process, at least three UMB base stations and wireless signal sending devices are required to cooperate in the execution. Among them, the UMB base station and the wireless signal sending device are used to determine the specific location information. It should also be noted that during the execution process, the mobile terminal and the wireless signal sending device are always bound and move at the same time. Based on the technical solution of the embodiment of the present disclosure, combined with the advantage of high accuracy in determining the position based on the UWB base station, the target wireless signal strength of the current position can be determined more accurately.

[0032] Example 1

[0033] Figure 1 This is a flow chart of a UWB-enabled wireless signal strength determination method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to situations where the wireless signal strength corresponding to any indoor location is determined. The method can be executed by a UWB-enabled wireless signal strength determination device, which can be implemented in the form of software and / or hardware. The hardware can be a mobile electronic device, which can execute the UWB-enabled wireless signal strength determination method provided by this technical solution.

[0034] like Figure 1 As shown, the method includes:

[0035] S110: Receive data to be used sent by a wireless signal sending device.

[0036] It should be noted that the technical solutions provided in the embodiments of the present invention are implemented based on a mobile terminal, which can be a mobile phone, a tablet computer, or a smart wearable device.

[0037] The wireless signal transmitting device refers to a device that can continuously transmit pulses or data frames to communication facilities such as base stations deployed in the surrounding area. In the embodiment of the present invention, the base station can be a UWB base station. The wireless signal transmitting device can be an independent hardware device, which usually has its own processor, storage and wireless communication module. Figure 2 As shown, the wireless signal transmitting device as an independent hardware device can communicate and transmit information with the base station via wireless signals. The wireless signal transmitting device can also be a part integrated into other hardware devices, for example, embedded in a product or a mobile terminal.

[0038] It should be noted that Ultra Wide Band (UWB) is a wireless technology that operates within a wide spectrum range and transmits data in extremely short pulses or large bandwidth. UWB pulse duration is usually very short and the baud rate is extremely high, so it can achieve indoor positioning or ranging with centimeter-level or even higher accuracy. Figure 3 As shown, a UWB base station refers to a UWB signal transceiver device that is fixedly deployed in space and can listen to UWB signals sent from wireless signal transmitting devices. In order to obtain good coverage and reliable measurement, at least three UWB base stations need to be installed in different corners or at different heights of the positioning area. When installing a UWB base station, you can first confirm the main activity areas of the wireless signal transmitting equipment. The UWB base station layout should cover these areas and leave appropriate margins. The deployment locations of UWB base stations should be as dispersed as possible, and the relative positions between base stations can maintain a certain geometric distribution. When deploying UWB base stations, try to choose places with unobstructed sight or fewer obstacles. If the environment is more complex, the number of UWB base stations can be increased. When there are multiple UWB base stations, time synchronization is required between the base stations.

[0039] It should also be noted that, in embodiments of the present invention, a wireless signal transmitting device can exchange data with a UWB base station. The wireless signal transmitting device can send UWB signal packets to the UWB base station, and the wireless signal transmitting device can also receive messages fed back by the UWB base station based on messages sent by the wireless signal transmitting device. For example, the wireless signal transmitting device can send a UWB signal packet to the UWB base station, and the UWB signal packet can include timestamp information. The wireless signal transmitting device can receive UWB signal packets fed back by the UWB base station, and the UWB signal packet can also include timestamp information.

[0040] The wireless signal transmitting device sends a message to a UMB base station. After receiving the message, the UMB base station processes the message and feeds back relevant data to the wireless signal transmitting device. The message-related data sent by the wireless signal transmitting device and the message-related data fed back by the UMB base station to the wireless signal transmitting device are used as data to be used. The data to be used includes first time data based on when the wireless signal transmitting device sends a first message to at least three UWB base stations, and second time data based on when the wireless signal transmitting device receives a second message corresponding to the first message fed back by the at least three UWB base stations to the wireless signal transmitting device.

[0041] It should be noted that the first message refers to the message sent by the wireless signal transmitting device to at least three UWB base stations. The first message sent by the wireless signal transmitting device to the UWB base station is typically a request message. Common content of the first message may include: the wireless signal transmitting device's ID, the timestamp of the wireless signal transmitting device sending the wireless signal to the UWB base station, i.e., a high-precision clock value or signal strength information. At the moment the wireless signal transmitting device begins or completes transmitting the first message, its internal timing module generates or reads a high-precision clock value. This clock value serves as the first time data. After at least three UWB base stations receive the first message from the wireless signal transmitting device, the UWB base station sends back a second message to the wireless signal transmitting device based on the first message. The second message sent back by the UWB base station to the wireless signal transmitting device is typically a response message, used to inform the wireless signal transmitting device of the wireless signal strength information measured by the UWB base station or other relevant information. For example, the UWB base station may send messages to the wireless signal transmitting device regarding system status, clock synchronization, calibration, or other parameters. At the moment the wireless signal transmitting device receives the second message, its internal timing module generates or reads a high-precision clock value, which serves as the second time data. The purpose of the wireless signal transmitting device sending the first message to the UWB base station and receiving the second message corresponding to the first message is to obtain the current location information of the wireless signal transmitting device.

[0042] Specifically, first, establish an environment layout with a wireless signal transmission device and at least three UWB base stations. Then, with the wireless signal transmission device and a mobile terminal configured as a local area network, move the wireless signal transmission device within the layout. The mobile terminal receives the data to be used, which is sent by the wireless signal transmission device. This data includes the high-precision clock value at the moment the wireless signal transmission device sends a message to the UWB base station. The data to be used also includes the high-precision clock value at the moment the wireless signal transmission device receives the feedback message from the UWB base station.

[0043] For example, Figure 4 As shown in the figure, after confirming the main activity area of the wireless signal transmission device, the UWB base stations are arranged according to a four-corner layout. Four UWB base stations are placed within the red box in the figure and the four UWB base stations are time-synchronized. Under the condition that the wireless signal transmission device and the mobile terminal are set up as a local area network, the wireless signal transmission device is moved within the layout environment. The mobile terminal receives the data to be used sent by the wireless signal transmission device. The data to be used includes the high-precision clock value at the moment when the wireless signal transmission device sends a message to the UWB base station. The data to be used also includes the high-precision clock value at the moment when the wireless signal transmission device receives the feedback message from the UWB base station.

[0044] In this embodiment, a wireless signal sending device sends a first message to at least three preset UWB base stations; and receives a second message corresponding to the first message fed back by the at least three UWB base stations.

[0045] It should be noted that before the wireless signal transmitting device sends the first message to the UWB base station, the UWB base station is pre-configured. The location of the UWB base station is usually pre-set, and the UWB base station is fixed at a known location based on the environment and requirements. Pre-configuration also means that the communication protocol between the wireless signal transmitting device and the UWB base station has been defined. When the wireless signal transmitting device sends a signal to the UWB base station, the UWB base station can understand and process these signals and then perform feedback operations on the signals. Pre-configuration also includes the wireless signal transmitting device being configured or registered with the UWB base station system. The UWB base station identifies and tracks the wireless signal transmitting device using its unique identifier to achieve effective communication between the wireless signal transmitting device and the UWB base station. In some systems, pre-configuration can also include the setting of a clock synchronization mechanism. The wireless signal transmitting device and the UWB base station need to be synchronized under pre-set conditions to ensure accurate timestamp calculation when sending and receiving messages, thereby ensuring positioning accuracy.

[0046] It should be noted that after the physical location and number of UWB base stations are planned, each one is assigned a unique identifier. These identifiers can be used to determine the order in which the UWB base stations send signals back to wireless signal transmitting devices. For example, numbers such as 1, 2, and 3 can be used as unique UWB identifiers.

[0047] Among them, at least three UWB base stations sequentially feed back the second message based on a preset sending order; the first time data of sending the first message and the second time data of receiving at least three second messages are encapsulated as data to be sent to the mobile terminal for use.

[0048] Optionally, time division multiple access technology can be used to assign specific time slots to each UWB base station for information transmission. This ensures that at any given moment, only one UWB base station is transmitting, thus avoiding conflicts. It should also be noted that the time of all base stations needs to be consistent, which is achieved by implementing a global clock or synchronization mechanism for the UWB base stations. Pre-setting the transmission order is an important step to ensure communication coordination between UWB base stations. UWB base stations transmit signals according to the pre-set transmission order, ensuring that multiple UWB base stations in the same network do not interfere with each other, achieving positioning accuracy and system stability, and can be effectively synchronized.

[0049] After collecting the first time data and the second time data, the collected time data are filled into a predefined data structure to complete the encapsulation process.

[0050] Specifically, the wireless signal sending device sends a message to the UWB base station. The UWB base station feeds back a corresponding second message based on the first message according to the number set by the UWB base station. Then, the wireless signal sending device receives the second message corresponding to the first message fed back by the UWB base station. Finally, the wireless signal sending device encapsulates the first time data of sending the first message and the second time data of receiving the second message as data to be used, and sends the data to be used to the mobile terminal through the TCP communication protocol. After receiving the data to be used, the mobile terminal parses the data structure and extracts the required information. And in order to deal with potential problems in data transmission, resend the data or request retransmission when necessary.

[0051] In this embodiment, the data to be used also includes distance information between the wireless signal sending device and at least three UWB base stations. The method also includes: for at least three UWB base stations, determining the distance information between the UWB base station and the wireless signal sending device based on the second time information, first time information and preset medium propagation speed corresponding to the UWB base station.

[0052] Among them, the distance information refers to the distance set of the straight-line distance between each UWB base station and the wireless signal sending device. The first time information is the timestamp when the wireless signal sending device sends the message to all UWB base stations at the same time. After receiving the first message, all UWB base stations will feedback the second message to the wireless signal sending device. The second time information includes the timestamp when the wireless signal sending device receives all the second messages. In the process of interaction between the UWB base station and the wireless signal sending device, the propagation speed of the message, that is, the preset medium propagation speed, mainly depends on the propagation speed of the electromagnetic wave in the medium. For the propagation of radio signals in the air, the speed is basically equivalent to the speed of light. In the air, the propagation speed of the message is about the speed of light, that is, about 299,792,458 meters per second.

[0053] It should be noted that the distance information between the UWB base station and the wireless signal transmitting device can be determined based on the first time information, the second time information, the preset medium propagation speed and the distance information calculation formula. The distance information calculation formula is:

[0054]

[0055] Where i represents a unique identifier assigned to each UWB base station, that is, it represents a different UWB base station. d(i) represents the distance between each UWB base station and the wireless signal transmitting device. c represents the preset medium propagation speed. i represents the second time information, that is, the time when the wireless signal transmitting device receives the signal from each UWB base station. t represents the first time information, that is, the signal transmitting time of the wireless signal transmitting device.

[0056] Specifically, the wireless signal transmitting device first obtains the first time information when it simultaneously transmits a message to all UWB base stations. Then, in the order of the UWB base station identifiers, the wireless signal transmitting device sequentially obtains the second time information when each UWB base station sends back a signal to the wireless signal transmitting device. After obtaining the first and second time information and the preset medium propagation speed, the distance information between each UWB base station and the wireless signal transmitting device is calculated using a distance information calculation formula. After obtaining the distance information, the distance information is used as data to be used and transmitted to the mobile terminal.

[0057] In this embodiment, the data to be used is presented in a preset format, including a message frame header, a polling number, a timestamp, distance information between at least three UWB base stations and the wireless signal transmitting device, and a message frame tail.

[0058] The message header is the information appended to the front of the data packet to be used, used to convey control information and metadata. The message trailer is the information appended to the end of the data packet to be used, typically used for error detection and verification. The polling count represents the number of times data is obtained within a period of time.

[0059] It should be noted that presenting the data to be used in a preset format helps ensure a consistent presentation of the data, allowing users to quickly identify and understand the data. When the data to be used is presented in a preset format, analyzing and comparing multiple data sets becomes easier. Furthermore, when the data to be used is presented in a preset format, the preset format facilitates further processing of the data using automated tools. For example, data presented in a preset format can be directly input into a database, analysis software, or other system, eliminating the need for manual data calculations. This is particularly important when the data volume is large or the data processing is complex.

[0060] Specifically, the data to be used sent by the wireless signal sending device and received by the mobile terminal is presented in a preset format.

[0061] For example, 55AA26000D0A5800001A7300001478000010B600001834FBDB can be data to be used in a preset format. 55AA is the message frame header. FBDB is the message frame trailer. 26 represents the polling number. 000D0A58 represents the timestamp. 00001A73, 00001478, 000010B6, and 00001834 represent the distance information between four UWB base stations and the wireless signal transmitting device, respectively.

[0062] S120: Obtain at least one target power.

[0063] The target power is the signal receiving power corresponding to the current position of the mobile terminal, and the current position is the current position of the wireless signal transmitting device and the mobile terminal.

[0064] It should be noted that signal received power refers to the power strength of the wireless signal received by a mobile terminal in wireless communication. For example, signal received power can be the power strength of the 5G signal received by a mobile phone in wireless communication. The mobile terminal can scan and record the strength of the surrounding wireless signals at regular intervals to obtain the corresponding wireless signal received power at the current location. Because the mobile terminal may obtain one or more target powers during the process of the wireless signal transmitting device sending the first message to the UWB base station and the wireless signal transmitting device receiving the second message fed back by the UWB base station, the mobile terminal obtains at least one target power.

[0065] In this embodiment, the positions of the mobile terminal and the wireless signal sending device change synchronously during the movement.

[0066] It's important to note that mobile devices and wireless signal transmitters typically transmit and receive signals at regular intervals. To accurately measure the distance from a mobile device to a UWB base station and determine positioning, it's crucial to ensure that the positions of the mobile device and the wireless signal transmitter change synchronously during wireless signal transmission. This synchronized movement of the mobile device and the wireless signal transmitter ensures real-time updates of the mobile device's location information, providing more precise positioning results. This is crucial for efficient and accurate positioning.

[0067] Specifically, during the movement process, it is ensured that the positions of the mobile terminal and the wireless signal transmitting device are always synchronized. Figure 5 As shown in the figure, when the mobile terminal is started, the time interval for obtaining the target power can be set in the mobile terminal interface. After the time interval for obtaining the target power is set on the mobile terminal, the control for obtaining the target power is triggered, and the mobile terminal can obtain the signal receiving power corresponding to the current location according to the set time interval. Figure 6 As shown, when the mobile terminal is in working state, the data to be used and the target power presented in a preset format can be obtained.

[0068] S130: Determine a target wireless signal strength at the current location based on the data to be used and at least one target power.

[0069] The target wireless signal strength refers to the strength of the wireless signal power value received by the mobile terminal at the current location in the wireless communication system.

[0070] It should be noted that determining the target wireless signal strength at the current location is intended to measure the signal propagation effect and quality. In communication and positioning systems, the magnitude of the wireless signal strength directly reflects the efficiency and reliability of signal transmission. Determining the target wireless signal strength at the current location not only helps assess network coverage and the positioning accuracy of the device, but also provides information about the distance between the device and the base station, thereby optimizing signal coverage and improving positioning accuracy. Low wireless signal strength can sometimes indicate signal interference, obstructions, or device failure. Monitoring wireless signal strength helps identify and resolve these issues. Furthermore, in dense wireless communication environments, wireless signal strength helps identify interference sources and perform interference management and channel selection, thereby improving overall system performance. In embodiments of the present invention, a received wireless signal strength indicator (RSSI) can be used to characterize wireless signal strength. RSSI is the most commonly used wireless signal strength metric, typically expressed in dBm. RSSI measures the power strength of the received wireless signal.

[0071] Optionally, after determining the target wireless signal strength at the current location, if the wireless signal strength is weak, it may be necessary to deploy devices such as signal amplifiers, repeaters, or relay stations to improve the range and strength of the wireless signal. Based on this wireless signal strength information, the wireless network configuration can be adjusted, such as selecting an appropriate channel, adjusting transmit power, and increasing the number of base stations to ensure wider network coverage and stronger signals. In some mobile communication systems, the transmit power of devices can also be dynamically adjusted based on signal strength to achieve more efficient communication and minimize interference.

[0072] Specifically, after obtaining the data to be used, the first time data and the second time data are determined, and the target wireless signal strength at the current location is determined based on the first time data, the second time data, and at least one target power.

[0073] The technical solution of the embodiment of the present disclosure receives data to be used sent by a wireless signal transmitting device, wherein the data to be used includes first time data based on when the wireless signal transmitting device sends a first message to at least three UWB base stations, and second time data based on when the wireless signal transmitting device receives a second message corresponding to the first message fed back by the at least three UWB base stations to the wireless signal transmitting device. Then, at least one target power is obtained, wherein the target power is the wireless signal receiving power corresponding to the current position of the mobile terminal, and the current position is the current position of the wireless signal transmitting device and the mobile terminal. Finally, based on the data to be used and the at least one target power, the target wireless signal strength of the current position is determined. This solves the problem of inaccurate positioning of the measurement point, high time cost, and insufficient density of measurement points caused by manual positioning based on the position of the signal measurement point marked on the map when measuring the target wireless signal strength of the current position in the prior art. The embodiment of the present invention can determine the target wireless signal strength corresponding to the mobile position in real time during the synchronous movement of the mobile terminal and the wireless signal transmitting device. When a mobile device and a wireless signal transmitter move synchronously, if the movement covers the entire indoor area, the wireless signal strength measurement coverage is expanded to the entire indoor area, increasing the number of detection points and ensuring a high density of measurement points. This improves positioning accuracy and signal acquisition efficiency during wireless signal strength measurement.

[0074] Example 2

[0075] Figure 7 This is a flowchart of a method for determining wireless signal strength enabled by UWB according to an embodiment of the present invention. Based on the previous embodiment, this method further refines the method for determining the target wireless signal strength at the current location. For specific implementations, please refer to the technical solution of this embodiment. Technical terms that are identical or corresponding to those in the previous embodiment are not repeated here.

[0076] like Figure 7 As shown, the method specifically includes the following steps:

[0077] S210: Receive data to be used sent by a wireless signal sending device.

[0078] S220: Obtain at least one target power.

[0079] S230: Determine the wireless signal strength corresponding to the same time by processing the first time data and the reception time of at least one target power in the data to be used.

[0080] Specifically, after obtaining the data to be used, the mobile terminal may obtain first time data and second time data from the data to be used. The target power reception time is obtained. A target power whose reception time falls between the first time data and the second time data is determined. Then, based on the at least one target power, the wireless signal strength corresponding to the same time is determined.

[0081] For example, after obtaining the data to be used, the mobile terminal can obtain the first time data and the second time data in the data to be used, thereby determining the specific time range in which the measurement occurred. Then, based on the specific time range in which the measurement occurred, all target powers whose reception times fall between the first time data and the second time data are determined. Furthermore, the average of all target powers within the time range can be used as the wireless signal strength corresponding to the current location at the same time.

[0082] S240: Determine the current location of the wireless signal sending device according to the distance information in the data to be used and the base station location information of at least three UWB base stations.

[0083] The base station location information of the UWB base station refers to the relative coordinates of all UWB base stations. For example, when there are four UWB base stations, the coordinates of one of the UWB base stations can be set to (0,0,0), and the relative coordinates of the remaining three UWB base stations can be determined based on the measured distances.

[0084] Specifically, when the wireless signal sending time of the wireless signal sending device is t, the signal receiving time when the wireless signal sending device receives the signal from the first UWB base station is t1, the signal receiving time when the wireless signal sending device receives the signal from the second UWB base station is t2, the signal receiving time when the wireless signal sending device receives the signal from the third UWB base station is t3, and the signal receiving time when the wireless signal sending device receives the signal from the fourth UWB base station is t4, based on the signal propagation speed, it can be determined that the distance information between the first UWB base station and the wireless signal sending device is d1, the distance information between the second UWB base station and the wireless signal sending device is d2, the distance information between the third UWB base station and the wireless signal sending device is d3, and the distance information between the fourth UWB base station and the wireless signal sending device is d4. Furthermore, assuming that the spatial location information of the first UWB base station is (x0, y0, z0), assuming that the spatial location information of the second UWB base station is (x1, y1, z1), assuming that the spatial location information of the third UWB base station is (x2, y2, z2), assuming that the spatial location information of the fourth UWB base station is (x3, y3, z3). All distance information is sent to the mobile terminal. The mobile terminal obtains the spatial location information of at least three UWB base stations and the distance information between the UWB base stations and the wireless signal transmitting device. Assuming that the current location of the wireless signal transmitting device is (x, y, z), according to d1= as well as The current location (x, y, z) of the wireless signal transmitting device can be determined.

[0085] S250: Use the wireless signal strength as the target wireless signal strength at the current location.

[0086] Specifically, after obtaining the location information of at least three UWB base stations and the distance information in the data to be used, the mobile terminal can calculate the current location of the wireless signal transmitting device. By matching the first time data, the second time data, and the reception time of the target power, the target power at the current location at the same time can be obtained, and ultimately the wireless signal strength at the current coordinate location can be determined.

[0087] The technical solution of the disclosed embodiment receives data to be used sent by a wireless signal transmitting device and obtains at least one target power. Then, by processing the first time data and the reception time of at least one target power in the data to be used, the wireless signal strength corresponding to the same moment is determined. Furthermore, the current location of the wireless signal transmitting device is determined based on the distance information in the data to be used and the location information of at least three UWB base stations. Finally, the wireless signal strength is used as the target wireless signal strength at the current location, thereby improving the positioning accuracy during wireless signal strength measurement.

[0089] Figure 8 This is a structural diagram of a UWB-enabled wireless signal strength determination device provided by an embodiment of the present disclosure. As shown in the figure, the device includes: a data receiving module 310 to be used, a target power acquisition module 320 and a target wireless signal strength determination module 330.

[0090] The data to be used receiving module 310 is used to receive the data to be used sent by the wireless signal sending device, wherein the data to be used includes first time data when the wireless signal sending device sends a first message to at least three UWB base stations, and second time data when the wireless signal sending device receives a second message corresponding to the first message fed back by the at least three UWB base stations to the wireless signal sending device; the target power acquisition module 320 is used to obtain at least one target power, wherein the target power is the signal receiving power corresponding to the current position of the mobile terminal, and the current position is the current position of the wireless signal sending device and the mobile terminal; the target wireless signal strength determination module 330 is used to determine the target wireless signal strength of the current position based on the data to be used and the at least one target power.

[0091] The technical solution of the embodiment of the present disclosure receives data to be used sent by a wireless signal transmitting device, wherein the data to be used includes first time data based on when the wireless signal transmitting device sends a first message to at least three UWB base stations, and second time data based on when the wireless signal transmitting device receives a second message corresponding to the first message fed back by the at least three UWB base stations to the wireless signal transmitting device. Then, at least one target power is obtained, wherein the target power is the signal receiving power corresponding to the current position of the mobile terminal, and the current position is the current position of the wireless signal transmitting device and the mobile terminal. Finally, based on the data to be used and the at least one target power, the target wireless signal strength of the current position is determined. This solves the problem in the prior art of manually locating the signal measurement points marked on the map when measuring the target wireless signal strength of the current position, which results in inaccurate positioning of the measurement points, high time cost, and insufficient density of measurement points. The embodiment of the present invention can determine the target wireless signal strength corresponding to the mobile position in real time during the synchronous movement of the mobile terminal and the wireless signal transmitting device. When a mobile device and a wireless signal transmitter move synchronously, if the movement covers the entire indoor area, the coverage of the wireless signal strength measurement is expanded to the entire indoor area, increasing the number of detection points and ensuring a high density of measurement points. This improves positioning accuracy during wireless signal strength measurement and increases wireless signal acquisition efficiency.

[0095] The data to be used encapsulation module is used to encapsulate the first time data of sending the first message and the second time data of receiving at least three second messages into the data to be used to be sent to the mobile terminal.

[0096] Based on the above technical solutions, the positions of the mobile terminal and the wireless signal sending device change synchronously during the movement.

[0097] Based on the above technical solutions, the device also includes: a distance information determination module, which is used to determine the distance information between the UWB base station and the wireless signal sending device for the at least three UWB base stations based on the second time information, first time information and preset medium propagation speed corresponding to the UWB base station.
