Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular to an anchor point connection method based on a non-inductive gate, a device and a storage medium. BACKGROUND

[0002] In the architecture of a traditional access control system, the communication mechanism between an anchor device such as a gate and a mobile terminal generally adopts a one-way connection mode, and its technical implementation path completes identity verification based on a preset signal strength threshold or a fixed timing protocol. For example, the mobile terminal establishes a one-way connection with the anchor point through a Bluetooth broadcast signal or a UWB signal, and the gate is triggered to open when the signal strength reaches the threshold.

[0003] However, in the context of a two-way passage gate, the mobile terminal may accidentally establish a connection with the reverse gate anchor point due to signal reflection or refraction, and the traditional access control system can only perceive the state of "connection establishment" and cannot perceive the actual spatial position relationship of the mobile terminal. When the mobile terminal establishes a connection with the wrong anchor point, the anchor point will still execute a release instruction, resulting in the erroneous opening of other gates.

[0006] To achieve the above-mentioned purpose, the present application provides an anchor point connection method based on a non-inductive gate, applied to a non-inductive gate, wherein the non-inductive gate faces anchor points in a first passage direction and a second passage direction, and the anchor points are opposite end anchor points. The method comprises the following steps:

[0007] When the anchor point receives a received signal strength indication value sent by a mobile terminal, it determines whether the mobile terminal is in the target passage direction of the anchor point according to the received signal strength indication value;

[0008] If the anchor point determines that the mobile terminal is not in the target passage direction of the anchor point, the opposite end anchor point of the anchor point is taken as the target connection anchor point of the mobile terminal, and the configuration information of the target connection anchor point is obtained;

[0009] After the anchor point obtains the configuration information of the target connection anchor point, a switching instruction is generated based on the configuration information, and the switching instruction is sent to the mobile terminal;

[0010] When the mobile terminal receives the switching instruction, it disconnects the connection with the anchor point, and sends a connection request to the target connection anchor point according to the configuration information.

[0011] In an embodiment, before the step of determining whether the mobile terminal is in the target passing direction of the anchor point according to the received signal strength indication value sent by the mobile terminal, the method further comprises:

[0017] After determining the target anchor point, the target anchor point determines the position of the mobile terminal according to the distance from each anchor point to the mobile terminal;

[0018] When the target anchor point determines that the mobile terminal enters the preset position area according to the position of the mobile terminal, receiving the identity authentication information sent by the mobile terminal.

[0019] In an embodiment, the non-inductive gate is provided with two or more than two gateways facing the first passing direction and the second passing direction, and after the step of determining whether the mobile terminal is in the target passing direction of the anchor point according to the received signal strength indication value sent by the mobile terminal, the method further comprises:

[0020] If the anchor point determines that the mobile terminal is not in the target passing direction of the anchor point, sending a ranging signal to the mobile terminal and determining the position of the mobile terminal according to the ranging signal;

[0021] determining a gateway in which the mobile terminal is located according to the position of the mobile terminal, and determining the target connection anchor point according to the gateway.

[0022] In an embodiment, after the step of determining whether the mobile terminal is in the target direction of passing through the anchor point according to the received signal strength indication value, the method further comprises:

[0023] If the anchor point determines that the mobile terminal is in the target direction of passing through the anchor point, the anchor point sends a ranging signal to the mobile terminal, and determines the position of the mobile terminal according to the ranging signal.

[0024] After the anchor point determines the position of the mobile terminal, the anchor point determines a gateway in which the mobile terminal is located according to the position of the mobile terminal, and determines a main anchor point according to the gateway, so that the main anchor point receives identity authentication information sent by the mobile terminal.

[0025] In an embodiment, the step of determining the position of the mobile terminal according to the ranging signal comprises:

[0026] After the anchor point sends a first ranging signal to the mobile terminal, the anchor point acquires a first distance value of the mobile terminal according to the ranging signal.

[0027] After the anchor point acquires the first distance value, the anchor point controls other anchor points on the same side as the anchor point to send a second ranging signal to the mobile terminal, and receives the second distance value sent by the other anchor points after the other anchor points determine a second distance value of the mobile terminal according to the second ranging signal.

[0028] After the anchor point acquires the first distance value and the second distance value, the anchor point determines a three-dimensional coordinate of the mobile terminal according to the first distance value and the second distance value.

When the anchor point receives the received signal strength indication value sent by the mobile terminal, it determines whether the mobile terminal is in the target passing direction of the anchor point according to the received signal strength indication value. If the anchor point determines that the mobile terminal is not in the target passing direction of the anchor point, the opposite anchor point of the anchor point is taken as the target connection anchor point of the mobile terminal, and the configuration information of the target connection anchor point is obtained. When the anchor point obtains the configuration information of the target connection anchor point, a switching instruction is generated based on the configuration information, and the switching instruction is sent to the mobile terminal. When the mobile terminal receives the switching instruction, it disconnects the connection with the anchor point, and sends a connection request to the target connection anchor point according to the configuration information.

[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0051] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings in the specification and the specific embodiments.

[0052] In the architecture of the traditional access control system, the communication mechanism between the anchor device such as the gate and the mobile terminal generally adopts a one-way connection mode, and the technical implementation path is to complete identity verification based on a preset signal strength threshold or a fixed timing protocol. For example, the mobile terminal establishes a one-way connection with the anchor through a Bluetooth broadcast signal or a UWB signal, and triggers the gate to open when the signal strength reaches the threshold.

[0053] However, in the two-way gate scene, the mobile terminal may accidentally establish a connection with the reverse gate anchor due to signal reflection or refraction, and the traditional access control system can only perceive the state of "connection establishment" and cannot perceive the actual spatial position relationship of the mobile terminal. When the mobile terminal establishes a connection with the wrong anchor, the anchor will still execute the release instruction, causing the other gate to be opened by mistake.

[0054] In view of the above problems, the present application proposes an anchor connection method based on a non-inductive gate, which is applied to a non-inductive gate. The anchors of the non-inductive gate facing the first and second passing directions are opposite end anchors. When the anchor receives a received signal strength indication value sent by a mobile terminal, it determines whether the mobile terminal is in the target passing direction of the anchor according to the received signal strength indication value. If the anchor determines that the mobile terminal is not in the target passing direction of the anchor, the opposite end anchor of the anchor is taken as the target connection anchor of the mobile terminal, and the configuration information of the target connection anchor is obtained. When the anchor obtains the configuration information of the target connection anchor, a switching instruction is generated based on the configuration information, and the switching instruction is sent to the mobile terminal. When the mobile terminal receives the switching instruction, the connection with the anchor is disconnected, and a connection request is sent to the target connection anchor according to the configuration information.

[0055] The above method determines the direction of the mobile terminal through the received signal strength indication value, can actively identify whether the mobile terminal establishes a connection with the wrong anchor, and avoids the misopening of the gate caused by signal reflection or refraction. Even if the mobile terminal is mistakenly connected to the reverse anchor, the mobile terminal can be switched to connect to the opposite end anchor, so that the gate is only opened in the expected direction, and the passing efficiency is improved.

[0056] Based on this, the first embodiment of the present application provides an anchor connection method based on a non-inductive gate, which is applied to a non-inductive gate. The anchors of the non-inductive gate facing the first and second passing directions are opposite end anchors. Referring to Figure 1 In this embodiment, the anchor connection method based on the non-inductive gate includes steps S10-S40:

[0057] Step S10, when the anchor receives a received signal strength indication value sent by a mobile terminal, it determines whether the mobile terminal is in the target passing direction of the anchor according to the received signal strength indication value.

[0058] It should be noted that the received signal strength indication (RSSI) value is used to measure the strength of the wireless signal detected by the receiving end in wireless communication. In this embodiment, the received signal strength indication value represents the signal strength of the signal transmitted by the anchor point and received by the mobile terminal such as a mobile phone.

[0059] It should also be noted that the target traffic direction of the anchor point refers to the corresponding traffic direction of the gate where the anchor point is located. As shown in Figure 2 , the gate in the figure is provided with anchor point 1, anchor point 2, anchor point B and anchor point C. The first traffic direction of the gate can be the entrance direction, i.e. the direction from gate 1 to gate 3, and the second traffic direction of the gate can be the exit direction, i.e. the direction from gate 3 to gate 1. Anchor point 1 and anchor point 2 are located on the entrance side of the gate, and anchor point B and anchor point C are located on the exit side of the gate. In Figure 2 , the target traffic direction of anchor point 1 refers to the traffic direction of the entrance side where anchor point 1 is located, i.e. the direction of gate 1. That is, when the mobile terminal is located at gate 1, the target traffic direction of the mobile terminal at anchor point 1 and anchor point 2.

[0060] Optionally, the anchor point is provided with a directional antenna array to concentrate the signal energy in the target traffic direction of the anchor point, forming a fan-shaped radiation field facing the target traffic direction. Through the above steps, when the main lobe direction of the antenna is aligned with the target traffic direction, the signal strength in the target traffic direction will be significantly enhanced. That is, when the mobile terminal is in the target traffic direction of the anchor point, the received signal strength is larger, and therefore the received signal strength indication value is also relatively larger. Because the back lobe direction of the antenna is aligned in the opposite direction of the target traffic direction, the antenna gain is suppressed, making the signal strength in the opposite direction weaker. When the mobile terminal is not in the target traffic direction of the anchor point, the received signal strength is smaller, and the received signal strength indication value is also relatively smaller.

[0061] Optionally, the gate machine metal shell is provided between the anchor points of the non-inductive gate. It can be understood that the gate machine metal shell as an electromagnetic shield can cause reflection loss and absorption loss to electromagnetic waves. Therefore, a thicker gate machine metal shell can also be provided on the gate opposite to the target traffic direction of the anchor point to weaken the signal strength in the area opposite to the target traffic direction. The metal shell will reflect part of the electromagnetic waves, reducing the signal penetration into the opposite area of the anchor point, and at the same time, the conductivity of the metal material will cause eddy current loss during the penetration of the electromagnetic waves, further weakening the signal strength and generating a large attenuation effect on the signal in the opposite direction. This attenuation effect can further reduce the signal strength of the anchor point received by the mobile terminal when the mobile terminal is not in the target traffic direction of the anchor point.

[0062] By combining the aforementioned anchor antenna directivity design with metal casing shielding, the anchor point can create a significant difference in signal strength between the forward and reverse directions. Therefore, when the anchor point receives a received signal strength indication value from the mobile terminal, it can compare the received signal strength indication value with a set threshold: if the received signal strength indication value is greater than the threshold, it is determined that the mobile terminal is in the target travel direction of the anchor point; if the received signal strength indication value is less than the threshold, it is determined that the mobile terminal is not in the target travel direction of the anchor point.

[0063] Step S20: If the anchor point determines that the mobile terminal is not in the target travel direction of the anchor point, then the opposite anchor point of the anchor point is taken as the target connection anchor point of the mobile terminal, and the configuration information of the target connection anchor point is obtained.

[0064] The opposite anchor point refers to the anchor point on the other side of the same gate as the current anchor point. Figure 2 For example, anchor point B is the opposite anchor point of anchor point 2, and anchor point C is the opposite anchor point of anchor point 1. When the signal strength indicator value of the mobile terminal determines that the mobile terminal is not in the target direction of travel of the anchor point, it means that the mobile terminal is connected to the wrong anchor point. At this time, the opposite anchor point is taken as the target connection anchor point of the mobile terminal, and a configuration information request is sent to the opposite anchor point to obtain the configuration information of the target connection anchor point.

[0065] For example, suppose in Figure 2 In the process, when the mobile terminal is in gate 1, it incorrectly connects to anchor point B. When anchor point B determines that the mobile terminal is not in the target passage direction based on the signal strength indication value sent by the mobile terminal, it takes its opposite anchor point, i.e., anchor point 2, as the target connection anchor point of the mobile terminal and sends a configuration information request to anchor point 2 to obtain the configuration information of anchor point 2.

[0066] Optionally, in order to more accurately verify the location of the mobile terminal, when the anchor point determines that the mobile terminal is not in the target travel direction, the location of the mobile terminal can be further determined based on the ranging signal, and the target connection anchor point of the mobile terminal can be determined based on the location of the mobile terminal.

[0067] When the signal strength indicator value of the mobile terminal indicates that the mobile terminal is not in the target travel direction of the anchor point, it means that the mobile terminal is connected to the wrong anchor point. To verify whether the mobile terminal is truly not in the target travel direction, the anchor point can send a ranging signal to the mobile terminal to obtain its position. Specifically, a Cartesian coordinate system is established with the anchor point as the origin, the target travel direction of the anchor point as the X-axis, and the extension direction of the line connecting the anchor points on the same side of the gate as the Y-axis. The value of the mobile terminal in the X-axis direction of the Cartesian coordinate system is obtained, and the sign of this value determines whether the mobile terminal is truly in the target travel direction of the anchor point.

[0068] Exemplarily, as shown in Figure 3 When the mobile terminal is at Gateway 1, the wrong connection is made to Anchor B, and Anchor B determines that the mobile terminal is not in the direction of the target passage, i.e., the direction of Gateway 3, by the signal strength indication value sent by the mobile terminal. Anchor B sends a Poll frame to the mobile terminal through the UWB module to start the two-way ranging, obtains the ranging value with the mobile terminal, controls the same side Anchor C to send a Poll frame to the mobile terminal for two-way ranging, and receives the ranging value sent by Anchor C with the mobile terminal. A rectangular coordinate system is established with Anchor B as the origin. The three-dimensional coordinates of the mobile terminal are obtained by the ranging values of Anchor C and Anchor B, combined with the angle of arrival (AOA) information.

[0069] Specifically, it is assumed that the coordinates of Anchor B are B (x1, y1, z1), the coordinates of Anchor C are C (x2, y3, z2), and the mobile terminal is P (x, y, z). The distances to the two anchors are d1 and d2, respectively. According to the distance formula between two points in a three-dimensional space, two spherical equations can be written as:

[0070]

[0071] For Anchor B, it is assumed that the azimuth angle of the measured signal arrival is θ1, the elevation angle is , and the direction vector is: . The direction vector is collinear with , so:

[0072]

[0073] Similarly, for Anchor C, we have:

[0074]

[0075] The above two equations are eliminated to obtain:

[0076]

[0077] Substituting x, y, and z into the spherical equation, we can solve k1 = ±d1. Since the distance is positive, we take k1 = d1, thus uniquely determining the position of P on the direction vector of Anchor B.

[0078] Similarly, for Anchor C, we have:

[0079]

[0080] Combining k2 = d2, we obtain another set of coordinate expressions. By combining the two sets of coordinate expressions, we obtain a linear equation system about x, y, and z. For example, comparing the expressions of x: Similarly, the equations for y and z are obtained. Obviously, the AOA direction vectors of the two anchor points are not collinear, and thus x, y and z have a unique solution.

[0081] After the coordinates of the mobile terminal are obtained, the target passing direction of the mobile terminal relative to the anchor points can be determined. For example, if x is positive, it indicates that the mobile terminal is in the target passing direction of anchor point B, and if x is negative, it indicates that the mobile terminal is not in the target passing direction of anchor point B.

[0082] It can be understood that the above ranging method is only one feasible implementation scheme of the embodiment, and in other embodiments, the position of the mobile terminal can also be obtained by adding a movable anchor point to construct equations.

[0083] In step S30, after the anchor point obtains the configuration information of the target connection anchor point, a switching instruction is generated based on the configuration information, and the switching instruction is sent to the mobile terminal.

[0084] In step S40, after the mobile terminal receives the switching instruction, the connection with the anchor point is disconnected, and a connection request is sent to the target connection anchor point according to the configuration information.

[0085] In the above example, it is assumed that after anchor point B obtains the configuration information of anchor point 2, such as the connection address, HUS_Session_ID (session identifier), Channel_ID (channel identifier), encrypted frequency hopping sequence and security authentication token of anchor point 2, a switching instruction such as a SwitchGate instruction packet is generated according to the configuration information, and then the SwitchGate instruction packet is sent to the mobile terminal. After the mobile terminal receives the SwitchGate instruction packet, the connection between the mobile terminal and anchor point B is disconnected, the SwitchGate instruction packet is parsed, and a connection request is sent to anchor point 2 through the connection configuration information of anchor point 2 in the SwitchGate instruction packet, and a connection is established with anchor point 2.

[0086] Optionally, after the target connection anchor point receives the connection request sent by the mobile terminal, a connection is established with the mobile terminal and ranging is performed, and after the target connection anchor point determines that the mobile terminal enters the preset position area of the non-inductive gate according to the distance from the mobile terminal, identity authentication information sent by the mobile terminal is received, and after the target connection anchor point verifies the mobile terminal according to the identity authentication information, the gate is controlled to be opened.

[0087] With reference to the above examples, after receiving the connection request sent by the mobile terminal, the anchor point 2 responds to the connection request and establishes a connection with the mobile terminal. Then, the anchor point 2 determines the distance from the mobile terminal according to the UWB signal or other ranging signals, judges the position of the mobile terminal, and when the mobile terminal enters the preset position area of the non-inductive gate, the anchor point 2 sends an identity information request to the mobile terminal, instructing the mobile terminal to provide identity authentication information. After obtaining the identity authentication information, the anchor point 2 verifies the mobile terminal, such as whether the mobile terminal is in the passable form in the system database. If the verification is successful, the gate is controlled to open.

[0088] Alternatively, if the anchor point determines that the mobile terminal is in the target passing direction of the anchor point, the anchor point directly sends an identity information request to the mobile terminal to obtain the identity authentication information of the mobile terminal after determining that the mobile terminal enters the preset position area of the non-inductive gate according to the distance from the mobile terminal, and after verifying the identity information of the mobile terminal, implements the subsequent ranging and gate opening control steps.

[0089] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above embodiment one can be referred to the above introduction, and the subsequent will not be described in detail. On this basis, before step S10, the anchor point connection method based on the non-inductive gate further includes steps S50-S70:

[0090] Step S50, when the mobile terminal detects the Bluetooth broadcast signals sent by the plurality of to-be-connected anchor points, determines the anchor point to be connected according to the strength of the Bluetooth broadcast signal, and after obtaining the configuration information of the anchor point from the Bluetooth broadcast signal corresponding to the anchor point, sends a connection request to the anchor point.

[0091] Exemplarily, taking Figure 2 for example, the four to-be-connected anchor points on the non-inductive gate can broadcast their configuration information through Bluetooth broadcast signals, and the Bluetooth broadcast signals are used to wake up the mobile terminal to obtain the broadcasted configuration information, and then the mobile terminal performs UWB (Ultra Wide Band) connection with the corresponding anchor point according to the configuration information. Alternatively, the Bluetooth broadcast names on the same gate side can also be set to be the same, thereby simplifying the scanning strategy on the mobile terminal side. For example, the Bluetooth broadcast names of the anchor point 1 and the anchor point 2 on the entrance side of the gate are set to be the same, and the Bluetooth broadcast names of the anchor point B and the anchor point C on the exit side of the gate are set to be the same. When the mobile terminal detects the Bluetooth broadcast signals sent by the plurality of to-be-connected anchor points, the Bluetooth broadcast with the strongest Bluetooth broadcast signal is preferentially selected, the UWB access configuration information contained in the Bluetooth broadcast is obtained, and the UWB connection with the to-be-connected anchor point is performed according to the configuration information, so as to improve the possibility of connecting to the correct anchor point.

[0092] Step S60, when the anchor point receives the connection request of the mobile terminal, connecting with the mobile terminal and sending a UWB signal to the mobile terminal.

[0093] Step S70, when the mobile terminal receives the UWB signal, determining the received signal strength indication value corresponding to the UWB signal and sending the received signal strength indication value to the anchor point.

[0094] It can be understood that, since the distance between the two sides of the gate on the import and export of the anchor point is not very large, the strength difference of the Bluetooth broadcast signal broadcasted by each anchor point will not be very large for the mobile terminal. In order to ensure that the mobile terminal can be connected to the correct anchor point, in addition to the preliminary Bluetooth broadcast signal strength judgment, it is also necessary to judge whether the mobile terminal is connected to the correct anchor point through the received signal strength indication value of the UWB signal with greater difference.

[0095] Exemplarily, when the anchor point receives the connection request of the mobile terminal, the anchor point is connected with the mobile terminal through UWB, forms a directional beam through a phased array antenna, and sends a UWB signal to the target direction of travel in a preset frequency band. The UWB chip of the mobile terminal captures the UWB signal pulse waveform at a predetermined sampling rate to obtain N continuous baseband signal samples r. Then, the mobile terminal sums the amplitude square of the N continuous baseband signal samples r to obtain an instantaneous power value P . Then, the instantaneous power value P is converted to a dBm unit to obtain a received signal strength indication value RSSI calibration offset. Wherein, the calibration offset can be set according to prior knowledge. After the mobile terminal calculates the received signal strength indication value RSSI, the received signal strength indication value RSSI is sent to the connected anchor point.

[0096] Based on the above embodiments of the present application, in the third embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be described in detail. On this basis, the anchor point connection method based on the non-inductive gate further includes steps S11-S13:

[0097] Step S11, if each anchor point on the non-inductive gate has established a connection with the mobile terminal, each anchor point determines the distance from the mobile terminal according to the UWB signal sent by the mobile terminal, and then takes the anchor point with the smallest distance from the mobile terminal as the target anchor point.

[0098] It can be understood that each anchor point usually corresponds to a travel direction of the non-inductive gate, and when the distance between the mobile terminal and a certain anchor point is the smallest, it can be inferred that the user is moving towards the area covered by the anchor point. For example, in Figure 4In the process, when the mobile terminal is close to anchor point 1 and the positioning distance between the mobile terminal and anchor point 1 is the smallest, it can be determined that the user intends to enter the gate from the direction of anchor point 1.

[0099] Optionally, in this embodiment, the anchor points on the sensorless gate are grouped into a network. For example, the anchor points are grouped into a network. Figure 4 The four anchor points on the sensorless gate—anchor point 1, anchor point 2, anchor point A, and anchor point B—are grouped together, and their Bluetooth broadcast names are set to be the same. When a mobile terminal approaches the sensorless gate, the Bluetooth broadcast signals from each anchor point wake up the mobile terminal, allowing it to obtain the UWB connection configuration information of each anchor point. The mobile terminal then establishes a UWB connection with each anchor point on the sensorless gate based on this configuration information.

[0100] When a mobile terminal approaches the sensorless gate, each anchor point on the gate can determine the distance between itself and the mobile terminal via UWB signals. The anchor point with the smallest distance from the mobile terminal is then used as the target anchor point to perform subsequent ranging, authentication, and gate opening control operations.

[0101] like Figure 4 As shown, when the mobile terminal is in gate 1, anchor points 1, 2, A, and B on the sensorless gate determine their distances from the mobile terminal based on the UWB signal. Figure 4 In the context of the mobile terminal, when the distance between the mobile terminal and anchor point 1 is the smallest, it indicates that the mobile terminal is in the target travel direction between anchor point 1 and anchor point 2. At this time, anchor point 1 with the smallest positioning distance can be selected as the target anchor point.

[0102] Step S12: After determining the target anchor point, the target anchor point determines the position of the mobile terminal based on the distance between each anchor point and the mobile terminal.

[0103] Step S13: After the target anchor point determines that the mobile terminal has entered the preset location area based on the location of the mobile terminal, it receives the identity authentication information sent by the mobile terminal.

[0104] After determining the target anchor point, since all anchor points on the contactless gate are networked as a group, the target anchor point can read the distances between any two other anchor points on the gate and the mobile terminal. The three-dimensional coordinates of the mobile terminal are then determined using these three distances. Based on the mobile terminal's three-dimensional coordinates, the target anchor point determines whether the mobile terminal has entered the gate's preset location area. If it has, it receives the authentication information sent by the mobile terminal and, upon successful verification, controls the gate to open.

[0105] In the embodiment, by networking the anchor points on the non-inductive gate as a group of anchor points, the mobile terminal can be connected with all the anchor points after synchronization ranging. The anchor point with the smallest distance from the mobile terminal is directly determined as the target anchor point based on the ranging result, without relying on RSSI to determine the gate made by the mobile terminal, so as to avoid the anchor point connection switching delay, and more quickly and simply determine the target anchor point for subsequent ranging, identity verification and gate opening control.

[0106] Based on the above-mentioned embodiments of the present application, in the fourth embodiment of the present application, the non-inductive gate is provided with two or more gates in the first and second passing directions. The same or similar contents as the above-mentioned embodiments can be referred to the above description, and will not be described hereinafter. On this basis, when there are multiple gates, please refer to Figure 5 , after step S10, the anchor point connection method based on the non-inductive gate further includes steps S80-S90:

[0107] Step S80, if the anchor point determines that the mobile terminal is not in the target passing direction of the anchor point, a ranging signal is sent to the mobile terminal, and the position of the mobile terminal is determined according to the ranging signal.

[0108] Step S90, when the anchor point determines the position of the mobile terminal, the gate where the mobile terminal is located is determined according to the position, and the target connection anchor point of the mobile terminal is determined according to the gate.

[0109] Exemplarily, referring to Figure 6 When there are multiple gates and gates, assuming that the mobile terminal is connected with the anchor point A in the gate 1, and the anchor point A determines that the mobile terminal is not in the target passing direction of the anchor point A through the received signal strength indication value sent by the mobile terminal, the gate position where the mobile terminal is located needs to be determined according to the ranging signal first, and then the target connection anchor point corresponding to the gate position is controlled to be connected with the mobile terminal.

[0110] For example, when the anchor point A determines that the mobile terminal is not in the target passing direction, a rectangular coordinate system can be established with the anchor point A as the origin, the target passing direction of the anchor point A as the X-axis direction, and the extension direction of the connecting line of the anchor points A, B and C on the same side as the Y-axis direction, the three-dimensional coordinates of the mobile terminal are determined according to the ranging signal, and the gate where the mobile terminal is located is determined according to the value of the Y-axis direction of the mobile terminal and the values of the Y-axis directions of the anchor points A, B and C.

[0111] In order to better understand the scheme given in the present example, the present example is further described in combination with a specific application scenario.

[0112] Assuming that the distance between each gate is fixedly set as 1 meter, a coordinate system is established with anchor point A as the origin, then the coordinates of anchor point A is (0, 0, 0), the coordinates of anchor point B is (0, 1, 0), and the coordinates of anchor point C is (0, 2, 0). If anchor point A determines the three-dimensional coordinates of the mobile terminal as (1, 1.5, -1) according to the ranging signal, it can be judged that the mobile terminal is displaced between anchor point B and anchor point C, and the target passing direction of the mobile terminal is known to be not at anchor point A, so the mobile terminal is determined to be located at gate 1.

[0113] After determining the gate where the mobile terminal is located, any anchor point in the direction of the gate is taken as the target connection anchor point. For example, in the above example, after determining that the mobile terminal is located at gate 1, anchor point 1 or anchor point 2 in the direction of gate 1 is taken as the target connection anchor point of the mobile terminal.

[0114] Optionally, the step of determining the position of the mobile terminal according to the ranging signal comprises steps S81-S83:

[0115] Step S81, after the anchor point sends a first ranging signal to the mobile terminal, a first distance value of the mobile terminal is obtained according to the ranging signal.

[0116] Step S82, after the anchor point obtains the first distance value, the other anchor points on the same side of the anchor point are controlled to send a second ranging signal to the mobile terminal, and after the other anchor points determine a second distance value of the mobile terminal according to the second ranging signal, the second distance value sent by the other anchor points is received.

[0117] For example, referring to Figure 6 , it is assumed that the mobile terminal is connected with anchor point 2 when it is located at gate 3. After anchor point 2 sends a first ranging signal to the mobile terminal, a first distance value is obtained. Then anchor point 2 controls anchor point 1 or anchor point 3 on the same side to send a second ranging signal to the mobile terminal. For example, anchor point 2 sends a ranging instruction packet containing the address identification of the mobile terminal to anchor point 1. It is assumed that anchor point 1 completes ranging to the mobile terminal after sending a second ranging signal to the mobile terminal, obtains a second distance value and reports it to anchor point 2. It should be noted that the first ranging signal and the second ranging signal described above can be UWB signals, or other signals that can be used to measure distance, which are not limited in the present application.

[0118] Step S83, after the anchor point obtains the first distance value and the second distance value, the three-dimensional coordinates of the mobile terminal are determined according to the first distance value and the second distance value.

[0119] For example, in the above example, when anchor point 2 receives the second distance value Afterwards, a three-dimensional rectangular coordinate system is established, with anchor point 2 as the origin, the target passing direction of anchor point 2 as the X-axis direction, and the extension direction of the connecting line of the same side gate anchor points as the Y-axis direction. The three-dimensional coordinates of the mobile terminal are solved according to the first distance value, the second distance value, and the coordinates of anchor point 1 and anchor point 2.

[0120] Optionally, when there are multiple gates and gateways, there are multiple anchor points on one side of the gate. In order to more accurately calculate the three-dimensional coordinates of the mobile terminal, the positioning error of the mobile terminal can be corrected by minimizing the difference between the ranging distance value and the calculated distance value, and the final three-dimensional coordinates are obtained. Among them, the ranging distance value refers to the distance value between the anchor point and the mobile terminal measured by the ranging signal, and the calculated distance value refers to the distance value between each anchor point and the mobile terminal calculated by the coordinates of the anchor points and the three-dimensional coordinates of the mobile terminal obtained by establishing the spherical equation and AOA angle measurement.

[0121] Exemplarily, the three-dimensional coordinates of the mobile terminal after calibration . Among them, represents the ranging distance value actually measured by the i-th anchor point, and ‖P- represents the Euclidean distance between the position P of the mobile terminal obtained by the circle equation , , and the coordinates of the i-th anchor point.

[0122] Optionally, after the anchor point determines the position of the mobile terminal, the step of determining the gateway in which the mobile terminal is located according to the position includes: after the anchor point determines the three-dimensional coordinates of the mobile terminal, the gateway in which the mobile terminal is located is determined according to the three-dimensional coordinates and the width of each gateway.

[0123] For example, in the above example, after establishing the rectangular coordinate system with anchor point 2 as the origin, the target passing direction of anchor point 2 as the X-axis direction, and the extension direction of the connecting line of the same side gate anchor points as the Y-axis direction, assuming that the gateway width is w, the coordinates of anchor point 2 are (0, 0, 0), the coordinates of anchor point 1 are (0, w, 0), and the coordinates of anchor point 3 are (0, -w, 0). Then, according to the value of the three-dimensional coordinates of the mobile terminal after calibration, it is judged which two anchor points the mobile terminal is located between, and then the gateway in which the mobile terminal is located is determined.

[0124] Based on the above embodiments of the present application, in the fifth embodiment of the present application, the same or similar contents as the above embodiments can be referred to in the above description, and will not be described in detail. On this basis, when there are multiple gateways, please refer to Figure 7 , after step S10, the anchor point connection method based on the non-inductive gate further includes steps S100-S110:

[0125] ​​Step S100, if the anchor point determines that the mobile terminal is in the target direction of travel of the anchor point, sends a ranging signal to the mobile terminal, and determines the position of the mobile terminal according to the ranging signal.

[0126] Step S110, after the anchor point determines the position of the mobile terminal, determines the gateway in which the mobile terminal is located according to the position, and determines the master anchor point according to the gateway, so that the master anchor point receives the identity authentication information sent by the mobile terminal.

[0127] In the above embodiment, the step of sending a ranging signal to the mobile terminal by the anchor point and determining the position of the mobile terminal according to the ranging signal, and the step of determining the gateway in which the mobile terminal is located according to the position are consistent with the above embodiment, and will not be repeated here.

[0128] After the anchor point determines the gateway in which the mobile terminal is located, any one of the anchor points at both ends of the gateway is taken as the master anchor point, and the master anchor point receives the identity authentication information sent by the mobile terminal. For example, the anchor point on the right side of the gateway is taken as the master anchor point, that is, after the mobile terminal establishes a connection with the anchor point 3 at the gateway 1, the anchor point 3 judges that it is located at the gateway 1, and the anchor point 1 on the right side of the gateway 1 is taken as the master anchor point, and the anchor point 2 is taken as the slave anchor point, and the ranging, identity authentication and control of opening the gate of the mobile terminal are performed by the anchor point 1.

[0129] For the purpose of facilitating understanding of the implementation process of the anchor point connection method based on the non-inductive gate obtained by combining the above embodiment, please refer to Figure 8 , Figure 8 A brief flowchart of the anchor point connection method based on the non-inductive gate is provided, specifically:

[0130] The anchor point first receives the received signal strength indication value sent by the connected mobile terminal, and then judges whether the mobile terminal is in the target direction of travel according to the received signal strength indication value.

[0131] In a single gate scenario, if the current anchor point determines that the connected mobile terminal is in the target direction of travel and judges that the mobile terminal enters the preset position area of the non-inductive gate through ranging positioning, the identity authentication information sent by the mobile terminal is received, and the subsequent verification and gate opening process is performed. If the current anchor point determines that the connected mobile terminal is not in the target direction of travel, the opposite anchor point is taken as the target connection anchor point of the mobile terminal, or a ranging signal is sent to the mobile terminal, the position of the mobile terminal is determined according to the ranging signal, the target connection anchor point is determined according to the position of the mobile terminal, and then a switching instruction is sent to the mobile terminal, so that the mobile terminal disconnects the connection with the current anchor point, and then connects with the correct target connection anchor point.

[0132] In the multi-gateway scenario, if the current anchor point determines that the connected mobile terminal is in the target passing direction, a ranging signal is sent to the mobile terminal, the position of the mobile terminal is determined according to the ranging signal, the gateway where the mobile terminal is located is determined according to the position of the mobile terminal, the main anchor point is determined according to the gateway, and when the mobile terminal enters the preset position area of the non-sensing gateway, the identity authentication information sent by the mobile terminal is received by the main anchor point. If the current anchor point determines that the connected mobile terminal is not in the target passing direction, a ranging signal is sent to the mobile terminal, the position of the mobile terminal is determined according to the ranging signal, the gateway where the mobile terminal is located is determined according to the position of the mobile terminal, the target connection anchor point is determined according to the gateway, a switching instruction is sent to the mobile terminal, so that the mobile terminal disconnects the connection with the current anchor point, and then connects with the correct target connection anchor point.

[0133] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the anchor point connection method based on the non-sensing gateway of the present application.
