Description

Technical Field

[0001] This application relates to the fields of financial technology and other related technologies, and more specifically, to an alarm method, device, electronic device and storage medium for safes. Background Technology

[0002] In the current technology, bank vault safes mainly rely on manual management. Generally, security cameras, access control systems and sensors are installed in the vault to monitor and manage the safes.

[0003] However, manual management methods typically cannot provide high-precision location information and can only monitor through devices such as cameras. Furthermore, relying on manual methods cannot provide real-time monitoring of the safe's location. Managers need to determine the safe's location by reviewing surveillance footage, making it impossible to promptly understand the safe's real-time location and status. This results in low monitoring efficiency for the safe and an inability to promptly alert authorities if the safe is not in the preset location.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

First, the target device sends N wireless signals to the terminal device. These N wireless signals are generated by the target device and are of the same frequency. The terminal device is mounted on a safe, and N is a positive integer. Then, the terminal device receives the N signal strength values ​​and N signal delay values ​​returned by the terminal device, and the target relative position between the terminal device and the target device is determined based on these values. Finally, if the target relative position differs from the preset relative position, an alarm message is generated. Each signal strength value and each signal delay value represent the signal strength and delay of a wireless signal detected by the terminal device. The preset relative position is the relative position between the terminal device and the target device when the safe is at the target position. The alarm message indicates that the safe is not at the target position.

[0020] As described above, this application utilizes wireless signal positioning. The target device sends a wireless signal to a terminal device installed on the safe. Based on the wireless signal strength and latency detected by the terminal device, the relative position between the terminal device and the target is determined, thereby confirming whether the safe containing the terminal device is located at the preset target position.

[0029] The present application will be further described below with reference to various embodiments.

[0030] Example 1

[0031] According to an embodiment of this application, an embodiment of an alarm method for a safe is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] Figure 1 This is a flowchart of an optional alarm method for a safe according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps:

[0033] Step S101: Send N wireless signals from the target device to the terminal device.

[0034] In step S101, N wireless signals are generated by the target device, and the N wireless signals are signals of the same frequency. The terminal device is set on the safe, and N is a positive integer.

[0035] Optionally, the target device can be a base station device or other device capable of generating and transmitting wireless signals, while the terminal device can be a wireless signal receiver or other device. Furthermore, the wireless signal can be any signal that can be transmitted wirelessly, such as WiFi, Bluetooth, ultrasonic, or RFID signals.

[0036] Alternatively, the size of the terminal device should be as small as possible. For example, the terminal device can be a chip set in a safe, so that wireless signal transmission and reception can be achieved without taking up too much space.

[0037] It should be noted that the N wireless signals are not transmitted simultaneously, but are transmitted once at preset intervals, for a total of N transmissions, so that the target device sends N wireless signals to the terminal device.

[0038] Step S102: Receive N signal strength values ​​and N signal delay values ​​returned by the terminal device.

[0039] In step S102, each signal strength value is the signal strength value of a wireless signal detected by the terminal device, and each signal delay value is the signal delay value of a wireless signal detected by the terminal device.

[0040] Optionally, after receiving a wireless signal, the terminal device will detect the signal strength and signal delay value. The signal strength value can be directly determined by the terminal device. The process for determining the signal delay value is as follows:

[0041] First, when the target device transmits a wireless signal, it sends the transmission time of the wireless signal as time information to the terminal device along with the wireless signal. Then, the terminal device receives the time information at the same time as receiving the wireless signal. Subsequently, the terminal device can determine the signal delay value of the wireless signal based on the reception time and the transmission time of the wireless signal.

[0042] Since the target device sent a total of N wireless signals to the terminal device, each wireless signal corresponding to a signal strength value and a signal delay value, the terminal device detected a total of N signal strength values ​​and N signal delay values. Finally, the terminal device returned N signal strength values ​​and N signal delay values ​​to the target device.

[0043] Step S103: Determine the target relative position between the terminal device and the target device based on N signal strength values ​​and N signal delay values.

[0044] Optionally, the target device can determine the target relative position between the terminal device and the target device based on the N signal strength values ​​and N signal delay values ​​returned by the terminal device. Specifically, the target device can determine a relative position between the terminal device and the target device (e.g., a first relative position) based on the N signal strength values ​​returned by the terminal device, and determine a relative position between the terminal device and the target device (e.g., a second relative position) based on the N signal delay values ​​returned by the terminal device. Then, the target device determines one of the relative positions from the first and second relative positions as the target relative position based on the specific scenario in which the target terminal and the terminal device are located.

[0045] Step S104: If the relative position of the target is different from the preset relative position, generate an alarm message.

[0046] In step S104, the preset relative position is the relative position between the terminal device and the target device when the safe is in the target position, and the alarm information is used to indicate that the safe is not in the target position.

[0047] For example, suppose the safe is at the target location, and the terminal device on the safe should be 10 meters directly in front of the target device (corresponding to the preset relative position mentioned above). However, if the target device determines, based on N signal strength values ​​and N signal delay values, that the terminal device is 5 meters directly to the left of the target device (corresponding to the target relative position mentioned above), then the safe is not actually at the target location. To promptly alert relevant personnel, the target device will generate an alarm message. This alarm message can be in various forms, such as voice, SMS, email, or light, to provide a timely reminder.

[0048] In addition, if the target relative position is the same as the preset relative position, the target device will determine that the safe is in the target position.

[0049] Based on the above steps S101 to S104, this application uses a method to determine the target relative position between the terminal device and the target device based on N signal strength values ​​and N signal delay values. First, the target device sends N wireless signals to the terminal device. These N wireless signals are generated by the target device and are of the same frequency. The terminal device is located on the safe, and N is a positive integer. Then, the terminal device receives the N signal strength values ​​and N signal delay values ​​returned by the terminal device, and determines the target relative position between the terminal device and the target device based on these values. Finally, if the target relative position differs from the preset relative position, an alarm message is generated. Each signal strength value is the signal strength value of a wireless signal detected by the terminal device, and each signal delay value is the signal delay value of a wireless signal detected by the terminal device. The preset relative position is the relative position between the terminal device and the target device when the safe is at the target position. The alarm message indicates that the safe is not at the target position.

[0050] As described above, this application utilizes wireless signal positioning. The target device sends a wireless signal to a terminal device installed on the safe. Based on the wireless signal strength and latency detected by the terminal device, the relative position between the terminal device and the target is determined, thereby confirming whether the safe containing the terminal device is located at the preset target position. This solution eliminates the need for security cameras, access control systems, and sensors, and eliminates the need for constant monitoring of the safe by management personnel. This not only saves on equipment costs but also improves the monitoring efficiency of the safe and enhances the timeliness of alarms for safes not in the preset position.

[0051] In one optional embodiment, in order to determine the target relative position between the terminal device and the target device based on N signal strength values ​​and N signal delay values, the target device calculates the average value of the N signal strength values ​​to obtain the average signal strength value corresponding to the terminal device receiving N wireless signals, and then inputs the average signal strength value into a pre-trained first model to obtain the first relative position output by the first model, wherein the first relative position is the relative position between the terminal device and the target device predicted by the first model based on the average signal strength value.

[0052] On the other hand, the target device also calculates the average of N signal delay values ​​to obtain the average signal delay value corresponding to the terminal device when receiving N wireless signals, and inputs the average signal delay value into the pre-trained second model to obtain the second relative position output by the second model. The second relative position is the relative position between the terminal device and the target device predicted by the second model based on the average signal delay value.

[0053] Finally, the target device determines the target relative position between the terminal device and the target device based on the first relative position and the second relative position.

[0054] Optionally, determining the relative position of the terminal device and the target device based solely on a single signal strength value or a single signal delay value may be highly unreliable, thus affecting the accuracy of the relative position determination. To avoid this problem, this application calculates the average signal strength value of N signal strength values ​​and determines the relative position of the terminal device and the target device based on this average signal strength value. Similarly, this application also calculates the average signal delay value of N signal delay values ​​and determines the relative position of the terminal device and the target device based on this average signal delay value.

[0055] In an optional embodiment, the first and second models described above are trained through the following steps, such as... Figure 2 As shown, it includes:

[0056] Step S201: Determine M test positions corresponding to the terminal device, wherein the M test positions include at least the first position, and the relative position between the terminal device and the target device when the terminal device is in the first position is the target relative position.

[0057] Optionally, the first position is the position of the terminal device when the safe is in the target position. In addition to the first position, the M test positions also include other positions.

[0058] Step S202: Obtain M test signal strength values ​​and M test signal delay values ​​detected by the terminal device based on M test locations. Each test signal strength value is the signal strength value of the wireless signal sent by the target device detected by the terminal device when it is located at a test location, and each test signal delay value is the signal delay value of the wireless signal sent by the target device detected by the terminal device when it is located at a test location.

[0059] Optionally, when the terminal device is in the first position, the test signal strength value and test signal delay value received by the terminal device are positive sample data. When the terminal device is not in the first position, the test signal strength value and test signal delay value received by the terminal device are negative sample data.

[0060] Step S203: Train the first model based on the M test signal strength values.

[0061] Step S204: Train the second model based on the delay values ​​of M test signals.

[0062] Optionally, in step S203 above, the target device uses each test signal strength value as first sample information and sets a first label for the first sample information, wherein the first label represents the relative position between the test position corresponding to the first sample information and the target device. Then, the target device inputs the first sample information and the first label corresponding to the first sample information into a preset first deep learning network, and obtains a first model after multiple iterations of training.

[0063] Optionally, in step S204 above, the target device uses each test signal delay value as second sample information and sets a second label for the second sample information, wherein the second label represents the relative position between the test position corresponding to the second sample information and the target device. Then, the target device inputs the second sample information and the second label corresponding to the second sample information into a preset second deep learning network, and obtains a second model after multiple iterations of training.

[0064] In one optional embodiment, in order to determine the target relative position between the terminal device and the target device based on the first relative position and the second relative position, the following describes how to determine the target relative position from the first relative position and the second relative position in four scenarios.

[0065] In the first scenario, when the first relative position and the second relative position are the same, the target device determines the first relative position or the second relative position as the target relative position.

[0066] Optionally, if the first relative position determined by the target device based on N signal strength values ​​and the second relative position determined based on N signal delay values ​​are the same, then the target device can use either the first relative position or the second relative position as the target relative position.

[0067] In the second scenario, when the first relative position and the second relative position are not the same, the target device calculates the variance of N signal strength values ​​and the variance of N signal delay values. Then, if the variance of the N signal strength values ​​is greater than the variance of the N signal delay values, the target device determines the second relative position as the target relative position; if the variance of the N signal strength values ​​is less than the variance of the N signal delay values, the target device determines the first relative position as the target relative position; if the variance of the N signal strength values ​​is equal to the variance of the N signal delay values, the target device randomly determines either the first relative position or the second relative position as the target relative position.

[0068] Optionally, this application provides a strategy for determining which of the first and second relative positions has higher reliability based on the volatility of N signal strength values ​​and the volatility of N signal delay values. Since variance characterizes volatility, and smaller volatility indicates less random data, a prediction result with smaller variance has higher reliability. Based on this, if the variance of the N signal strength values ​​is greater than the variance of the N signal delay values, the target device determines the second relative position as the target relative position; if the variance of the N signal strength values ​​is less than the variance of the N signal delay values, the target device determines the first relative position as the target relative position.

[0069] In the third scenario, when the first relative position and the second relative position are different, the target device obtains the number of signal transmission paths between the terminal device and the target device, where each signal transmission path is the path from the target device's wireless signal to the terminal device. Subsequently, if the number of signal transmission paths is greater than or equal to a preset number, the target device determines the second relative position as the target relative position; if the number of signal transmission paths is less than the preset number, the target device determines the first relative position as the target relative position.

[0070] Optionally, this application provides another strategy to determine which of the first and second relative positions is more reliable based on the presence of a significant multipath effect between the terminal device and the target device. The multipath effect refers to whether there are multiple signal transmission paths between the terminal device and the target device. When the number of signal transmission paths is greater than or equal to a preset number, it indicates a significant multipath effect between the terminal device and the target device. In this case, signal delay is usually more suitable for judging the appropriateness of the distance. This is because under the multipath effect, the wireless signal undergoes reflection, scattering, and diffraction along different paths during propagation, resulting in the wireless signal received by the terminal device having multiple propagation paths and different delays. That is, the signal delay variation under the multipath effect is more obvious. In this case, by measuring the signal delay, the signal propagation distance can be more accurately inferred.

[0071] In the third scenario, where the first relative position and the second relative position are different, the target device acquires the signal strength attenuation value of each wireless signal transmitted from the terminal device to the target device, obtaining N signal strength attenuation values. Then, it calculates the average of these N signal strength attenuation values ​​to obtain the average signal strength attenuation value. Finally, if the average signal strength attenuation value is greater than or equal to a preset threshold, the target device determines the first relative position as the target relative position; if the average signal strength attenuation value is less than the preset threshold, the target device determines the second relative position as the target relative position.

[0072] Optionally, this application provides another strategy to determine which of the first and second relative positions is more reliable based on whether there is a significant signal attenuation effect between the terminal device and the target device. Specifically, when the average signal strength attenuation value is greater than or equal to a preset threshold, it indicates a relatively significant signal attenuation effect between the terminal device and the target device. In this case, signal strength is generally more suitable for judging the appropriateness of the distance. This is because under a strong attenuation effect, the strength of the wireless signal will decrease with increasing distance; that is, the change in the wireless signal strength will be more significant. By measuring the signal strength, the distance the signal has propagated can be inferred.

[0073] As described above, this application utilizes wireless signal positioning. The target device sends a wireless signal to a terminal device installed on the safe. Based on the wireless signal strength and latency detected by the terminal device, the relative position between the terminal device and the target is determined, thereby confirming whether the safe containing the terminal device is located at the preset target position. This solution eliminates the need for security cameras, access control systems, and sensors, and eliminates the need for constant monitoring of the safe by management personnel. This not only saves on equipment costs but also improves the monitoring efficiency of the safe and enhances the timeliness of alarms for safes not in the preset position.
