[0019] Of course, the electronic device can also be a mailbox alarm device.

[0020] The following describes the relevant contents, concepts, meanings, technical issues, technical solutions, beneficial effects, etc. involved in the embodiments of this application.

[0021] First, some professional terms involved in this application are explained: A six-axis sensor is a composite sensor that integrates a three-axis accelerometer and a three-axis gyroscope. It can simultaneously detect two states of motion of an object in three-dimensional space. The three-axis accelerometer can measure the linear acceleration of an object in the X, Y, and Z directions, reflecting the speed of the object's movement (such as the push and pull force and speed increase or decrease when opening a door). The three-axis gyroscope can measure the angular velocity of an object around the X, Y, and Z axes, reflecting the speed of the object's rotational movement (such as the rate of change of the rotation angle when opening a door). In this application, the six-axis sensor is used to detect the opening and closing of the mailbox door (such as whether it is rotating, the rotation speed, and the push and pull force), providing data support for determining whether the mailbox door is open.

[0022] Mailbox alarm: refers to the function of detecting abnormal status of the mailbox (such as the mailbox door being illegally opened, internal items being stolen, foreign objects appearing, etc.) through sensors and transmitting abnormal information to managers or users.

[0023] See also Figure 1 , Figure 1 : This is a schematic diagram of the structure of a mailbox alarm device provided in an embodiment of the present application; it can be seen that the mailbox alarm device may include a six-axis sensor, a communication module, a control module, etc., which are not limited here, wherein: The six-axis sensor is used to collect data. It integrates a three-axis accelerometer and a three-axis gyroscope. It can detect the motion data of the mailbox door (acceleration, angular velocity changes) and identify "whether the mailbox door is open" (such as the motion characteristics when rotating, pushing or pulling); it can convert the motion data into electrical signals and transmit them to the communication module and / or control module in real time.

[0024] The communication module is used to transmit data. Common types include 4G modules, WiFi modules, and Bluetooth modules. It can receive "alarm instructions" from the control module and send information (such as "mailbox door abnormally opened") to the management personnel.

[0025] The control module coordinates the operations of other modules and is typically composed of a single-chip microcontroller or embedded chip. It receives and analyzes data from the six-axis sensor (to determine the mailbox door's motion status) to determine whether to trigger an alarm. If an alarm is triggered, it sends a "send alarm" command to the communication module.

[0026] It needs to be explained that in order to save costs, the structure of the mailbox alarm device can be simplified, the control module of the mailbox alarm device can be removed, and a cloud server can be used instead. The communication module can communicate with the cloud server, and the cloud server receives real-time data uploaded by the communication module (for example, the motion data of the mailbox door, etc.), and analyzes the data to determine whether to trigger an alarm, thereby realizing the functional replacement of the control module.

[0027] See also Figure 2 , Figure 2 This is a structural diagram of another mailbox alarm device provided in an embodiment of the present application; it can be seen that in addition to including a six-axis sensor, a communication module, and a control module, the mailbox alarm device can also include a power module, which supplies power to the mailbox alarm device.

[0028] See also Figure 3 , Figure 3This is a scenario application diagram of a mailbox alarm device provided by an embodiment of the present application. It can be seen that the mailbox alarm device is installed on the inner side wall of the target mailbox (in an area close to the door but not affecting the door's opening and closing) to prevent external damage. At the same time, it is close to the movement area of ​​the door, making it convenient for the six-axis sensor to detect the movement of the door (such as rotation, acceleration / angular velocity changes during pushing and pulling). When someone attempts to open the "mailbox door", the mailbox alarm device can execute the mailbox alarm method provided by the embodiment of the present application, as follows: Obtaining internal information of a first mailbox of the target mailbox; detecting target motion data of a mailbox door of the target mailbox by the six-axis sensor; Determine a target detection result according to the target motion data; the target detection result includes one of the following: the mailbox door is opened, the mailbox door is not opened; When the target detection result includes that the mailbox door is opened, obtaining the second mailbox internal information of the target mailbox; Determining target alarm information based on the internal information of the first mailbox and the internal information of the second mailbox; The target alarm information is sent to the administrator via the communication module to ensure mailbox security.

[0029] It should be explained that the above-mentioned mailbox alarm device can also execute part or all of the steps of the mailbox alarm method provided in the embodiment of the present application.

[0030] See also Figure 4 , Figure 4 This is a flowchart of a mailbox alarm method provided by an embodiment of the present application. The method is applied to a mailbox alarm device (hereinafter referred to as the device), which may include a six-axis sensor and a communication module. The mailbox alarm device is disposed inside a target mailbox. The method includes but is not limited to the following steps: S401: Obtain internal information of a first mailbox of the target mailbox.

[0031] In the embodiment of the present application, a six-axis sensor can be used to detect the movement state of the mailbox door (such as acceleration, angular velocity changes). When the door is detected to move from rest to movement (linear acceleration suddenly changes from 0), it is determined that the door opening has started. When the door is detected to return from movement to rest (linear acceleration returns to 0 and lasts for a certain period of time, such as 2 seconds), it is determined that the door opening has ended. The time difference between the start and end of the door opening is calculated to obtain the first door opening duration. In addition, a weighing sensor can be installed at the bottom of the target mailbox or under the mail carrying surface, and the pressure change is used to reflect the number of mails. The weighing data is obtained by the weighing sensor detection. The weighing sensor can be physically or communicatively connected to the communication module, thereby transmitting the weighing data to the above-mentioned device. Each time new mail is added, the weight increases, and the device can adjust the weight according to the unit mail weight (which can be pre-set Weight, such as the average weight of ordinary letters and small parcels), calculate the change in the number of mails (the weight change value is divided by the unit mail weight and rounded up), add the change in the number of mails and the initial mail quantity to obtain the first mail quantity. Similarly, the device may also include an environmental sensor, which detects the environmental data around the target mailbox through the environmental sensor to obtain the first environmental data. Specifically, the environmental data may include at least one of the following: temperature, humidity, light intensity, etc., which are not limited here. For example, assuming that the environmental data is temperature, the environmental sensor may be a temperature sensor, which detects the temperature around the target mailbox through the temperature sensor to obtain temperature data, that is, the first environmental data. Finally, the internal information of the first mailbox can be composed of the first door opening duration, the first mail quantity, and the first environmental data.

[0032] S402: Detect target motion data of the mailbox door of the target mailbox using the six-axis sensor.

[0033] In an embodiment of the present application, the six-axis sensor can be integrated with a three-axis accelerometer and a three-axis gyroscope; the six-axis sensor can be rigidly fixed on the inside of the mailbox door, close to the hinge (the rotation axis of the mailbox door), so that the X, Y, and Z axes of the six-axis sensor are consistent with the movement direction of the mailbox door (for example, the X-axis can point to the width direction of the mailbox door, the Y-axis can point to the height direction of the mailbox door, and the Z-axis can point to the thickness direction of the mailbox door), which facilitates subsequent data analysis.

[0034] In a specific embodiment, the sampling frequency of the six-axis sensor can be set first, for example, 50~100 Hz (i.e., data is collected 50~100 times per second) to ensure that the details of the rapid door opening action are captured. Then, the six-axis sensor is operated at the set sampling frequency to collect linear acceleration and angular velocity data of the mailbox door of the target mailbox. Specifically, the linear acceleration of the mailbox door on the X, Y, and Z axes can be collected by a three-axis accelerometer to obtain three linear acceleration data, and the angular velocity of the mailbox door on the X, Y, and Z axes can be collected by a three-axis gyroscope to obtain three angular velocity data, thereby obtaining target motion data.

[0035] S403. Determine a target detection result according to the target motion data; the target detection result includes one of the following: the mailbox door is opened, and the mailbox door is not opened.

[0036] Optionally, the target motion data includes: 3 linear acceleration data and 3 angular velocity data, each linear acceleration data corresponds to one angular velocity data, please refer to Figure 5 , Figure 5 This is a flow chart of a method for determining a target detection result provided by an embodiment of the present application. Step S403, determining the target detection result based on the target motion data, may include: Figure 5 Steps shown: A1. Determine the maximum linear acceleration corresponding to the three linear acceleration data and the maximum angular velocity corresponding to the three angular velocity data; A2. when the maximum linear acceleration is greater than a first preset linear acceleration, and / or the maximum angular velocity is greater than a first preset angular velocity, determining that the target detection result includes that the mailbox door is opened; A3. When the maximum linear acceleration is not greater than the first preset linear acceleration and the maximum angular velocity is not greater than the first preset angular velocity, determine the linear acceleration data corresponding to the maximum linear acceleration among the three linear acceleration data to obtain first linear acceleration data; determine the angular velocity data corresponding to the first linear acceleration data to obtain first angular velocity data; and determine the target detection result based on the maximum linear acceleration, the first linear acceleration data, and the first angular velocity data.

[0037] In the embodiment of the present application, the first preset linear acceleration and the first preset angular velocity can be preset in advance or defaulted.

[0038] In a specific embodiment, the maximum linear acceleration corresponding to the three linear acceleration data and the maximum angular velocity corresponding to the three angular velocity data can be determined. Specifically, the data in the three linear acceleration data can be compared two by two to find the maximum value therein, that is, the maximum linear acceleration. Similarly, the data in the three angular velocity data can be compared two by two to find the maximum value therein, that is, the maximum angular velocity. When the maximum linear acceleration is greater than the first preset linear acceleration, and / or the maximum angular velocity is greater than the first preset angular velocity, the target detection result can be determined as the mailbox door is open.

[0039] When the maximum linear acceleration is not greater than the first preset linear acceleration and the maximum angular velocity is not greater than the first preset angular velocity, the linear acceleration data corresponding to the maximum linear acceleration in the three linear acceleration data can be determined to obtain the first linear acceleration data. Specifically, it can be determined to which axis the maximum linear acceleration belongs, and the linear acceleration data corresponding to the axis can be recorded as the first linear acceleration data. Then, the angular velocity data corresponding to the first linear acceleration data is determined to obtain the first angular velocity data. Specifically, the target axis (one of the three axes X, Y, and Z) corresponding to the first linear acceleration data can be determined. Then, the corresponding angular velocity data can be found from the three angular velocity data according to the target axis, that is, the first angular velocity data. For example, if the target axis corresponding to the first linear acceleration data is the X axis, the angular velocity data corresponding to the X axis can be found from the three angular velocity data, that is, the first angular velocity data. Finally, the target detection result can be determined based on the maximum linear acceleration, the first linear acceleration data, and the first angular velocity data.

[0040] In this way, when the maximum linear acceleration (such as the impact force of violently pushing the door) exceeds the first preset linear acceleration, or the maximum angular velocity (such as the speed of rapid rotation of the door) exceeds the first preset angular velocity, it is directly determined that "the mailbox door is open". No complicated calculation is required to quickly determine that "the door is open", avoiding missed reports due to delays; when the motion data does not exceed the preset threshold (such as the door is lightly pushed but not fully opened, or slightly shaking), a secondary judgment is made based on the axis data corresponding to the maximum linear acceleration and the axis angular velocity data, thereby avoiding misjudgment.

[0041] Optionally, the first linear acceleration data includes multiple linear accelerations, and the multiple linear accelerations correspond to multiple first sampling times; the first angular velocity data includes multiple angular velocities, and the multiple angular velocities correspond to multiple second sampling times. Step A3, determining the target detection result based on the maximum linear acceleration, the first linear acceleration data, and the first angular velocity data, may include the following steps: B1. When the maximum linear acceleration is greater than the second preset linear acceleration, fitting is performed based on the multiple linear accelerations and the multiple first sampling times to obtain a first acceleration line; the abscissa of the first acceleration line is time, and the ordinate is linear acceleration; and the second preset linear acceleration is less than the first preset linear acceleration; B2. Fitting the multiple angular velocities and the multiple second sampling times to obtain a first angular velocity line, wherein the abscissa of the first angular velocity line is time and the ordinate is angular velocity; B3. Determine the target detection result according to the first acceleration line and the first angular velocity line; B4. When the maximum linear acceleration is not greater than the second preset linear acceleration, determine that the target detection result includes that the mailbox door is not opened.

[0042] In the embodiment of the present application, the second preset linear acceleration can be preset in advance or defaulted.

[0043] In a specific embodiment, when the maximum linear acceleration is greater than the second preset linear acceleration, fitting can be performed based on multiple linear accelerations and multiple first sampling times to obtain a first acceleration line. Specifically, each linear acceleration and its corresponding first sampling time can be combined to obtain multiple first coordinate points. Then, a straight line fitting method (for example, the least squares method) can be used to fit these multiple first coordinate points to obtain a first acceleration line. Then, fitting can be performed based on multiple angular velocities and multiple second sampling times to obtain a first angular velocity line. Specifically, the method for obtaining the first angular velocity line can be the same as the method for obtaining the first acceleration line. Then, the target detection result can be determined based on the first acceleration line and the first angular velocity line.

[0044] When the maximum linear acceleration is not greater than the second preset linear acceleration, the object detection result may be determined as the mailbox door is not opened.

[0045] In this way, when the maximum linear acceleration is not greater than the second preset linear acceleration, it is directly determined that "the mailbox door is not open" without the need for subsequent fitting analysis, thereby reducing the computing power consumption of the device (especially suitable for battery-powered low-power devices) and avoiding misjudging environmental vibrations as door opening actions. In addition, when the maximum linear acceleration is greater than the second preset linear acceleration, the data is fitted and analyzed to obtain the target detection result.

[0046] Optionally, step B3, determining the target detection result according to the first acceleration line and the first angular velocity line, may include the following steps: C1. Determine a first slope corresponding to the first acceleration line and a second slope corresponding to the first angular velocity line; C2. determining a ratio between the first slope and the second slope; C3. If the ratio is less than or equal to 0, determining that the target detection result is that the mailbox door is open; C4. If the ratio is greater than 0, determining a slope difference between the first slope and the second slope to obtain a target slope difference; C5. When the target slope difference is greater than a preset slope difference, determining that the target detection result is that the mailbox door is opened; C6. When the target slope difference is not greater than the preset slope difference, predicting the moment when the linear acceleration of the mailbox door reaches the first preset linear acceleration based on the first acceleration line to obtain a first predicted moment; C7. Determine a first time length between the first predicted moment and the current moment; C8. If the first time length is not greater than a preset time length, determining that the target detection result includes that the mailbox door is opened; C9. If the first time length is greater than the preset time length, predicting the time when the angular velocity of the mailbox door reaches the first preset angular velocity based on the first angular velocity line to obtain a second predicted time; C10. Determine a second time length between the second predicted moment and the current moment; C11. If the second time length is greater than the preset time length, determining that the target detection result includes that the mailbox door is not opened; C12. If the second time length is not greater than the preset time length, determine that the target detection result includes that the mailbox door is opened.

[0047] In the embodiment of the present application, the preset slope difference and the preset duration can be preset or defaulted in advance.

[0048] In a specific embodiment, the first slope corresponding to the first acceleration line and the second slope corresponding to the first angular velocity line can be determined. Specifically, the first linear equation y=ax+b of the first acceleration line can be obtained, where y is the linear acceleration value, x is the time point, a is the first slope, and b is the intercept. The first slope can be obtained according to the first linear equation. Similarly, the second slope can also be obtained. Then, the ratio between the first slope and the second slope can be determined, as follows: Ratio = first slope / second slope; The above formula yields a ratio. If the ratio is less than or equal to 0, it means the acceleration trend (first slope) and the angular velocity trend (second slope) are in opposite directions, or there is no trend in either direction (e.g., the first slope is 0). In this case, the target detection result can be determined to be that the mailbox door is open. For example, suppose the user initially pushes the door with considerable force (acceleration increases over time, the first slope is positive), and the door begins to rotate (angular velocity increases over time, the second slope is positive). The user then reduces the force (acceleration decreases over time, the first slope becomes negative), but the door continues to accelerate due to inertia (angular velocity continues to increase, the second slope remains positive). In this case, the first slope is negative and the second slope is positive, and the ratio is less than 0. However, the door is clearly in a "continuously open" state. Therefore, the target detection result can be determined to be that the mailbox door is open.

[0049] If the ratio is greater than 0, the slope difference between the first and second slopes can be determined to obtain the target slope difference. Specifically, the target slope difference can be obtained by subtracting the second slope from the first slope. When the target slope difference is greater than the preset slope difference, it indicates that the rate of change of acceleration and the rate of change of angular velocity are significantly different. For example, assuming the acceleration slope is 3.0 and the angular velocity slope is 0.5, the difference of 2.5 is greater than the preset slope difference of 1.0. This difference does not exist in "non-door opening motion" but rather indicates an "unsteady state" that may occur during the door opening process (such as uneven force or a door hinge suddenly smoothing after being stuck). In this case, the target detection result can be determined to be that the mailbox door is open.

[0050] When the target slope difference is not greater than the preset slope difference, the moment when the linear acceleration of the mailbox door reaches the first preset linear acceleration can be predicted based on the first acceleration line to obtain the first predicted moment. Specifically, the first preset linear acceleration can be substituted into the first linear equation for calculation to obtain the first predicted moment; then, the first time length between the first predicted moment and the current moment can be determined, for example, the first time length can be obtained by subtracting the current moment from the first predicted moment; if the first time length is not greater than the preset time length, it means that the linear acceleration of the mailbox door can reach the first preset linear acceleration in a shorter time, thereby achieving door opening, and then it can be determined that the target detection result includes that the mailbox door has been opened.

[0051] If the first time length is greater than the preset time length, the moment when the angular velocity of the mailbox door reaches the first preset angular velocity can be predicted based on the first angular velocity line to obtain a second predicted moment. Specifically, the second straight line equation corresponding to the first angular velocity line can be obtained, and the first preset angular velocity can be substituted into the second straight line equation for calculation to obtain the second predicted moment; then, the second time length between the second predicted moment and the current moment can be determined, for example, the second time length can be obtained by subtracting the current moment from the second predicted moment; if the second time length is greater than the preset time length, it is determined that the target detection result includes that the mailbox door is not opened.

[0052] If the second time length is not greater than the preset time length, it is determined that the target detection result includes that the mailbox door is opened.

[0053] In this way, the mailbox door status is judged through the multi-level progressive logic of "slope ratio → difference threshold → time prediction", and the "non-door opening movement" is filtered layer by layer to reduce misjudgment and improve the accuracy of mailbox door status judgment.

[0054] Optionally, when the target slope difference is not greater than the preset slope difference, the method may further include the following steps: D1. Determine the combined acceleration data corresponding to the three linear acceleration data; D2. Determine a second acceleration line corresponding to the combined acceleration data; the abscissa of the second acceleration line is time, and the ordinate is the combined acceleration; D3. Determine a maximum combined acceleration corresponding to the combined acceleration data and a third slope corresponding to the second acceleration line; D4. Determine the resultant angular velocity data corresponding to the three angular velocity data; D5. Determine a second angular velocity line corresponding to the resultant angular velocity data; the abscissa of the second angular velocity line is time, and the ordinate is the resultant angular velocity; D6. Determine a maximum angular velocity corresponding to the angular velocity data, and a fourth slope corresponding to the second angular velocity line; D7. Determine the target detection result according to the maximum resultant acceleration, the third slope, the maximum resultant angular velocity, and the fourth slope.

[0055] In an embodiment of the present application, the combined acceleration data corresponding to the three linear acceleration data can be determined first. Specifically, the three linear acceleration data correspond to the accelerations of the object (mailbox door) in the X-axis, Y-axis, and Z-axis directions in the three-dimensional space, respectively. These three accelerations are perpendicular to each other and together constitute the motion acceleration vector of the object (mailbox door) in space. The three linear acceleration data can be synthesized according to the principle of space vector synthesis to obtain the combined acceleration data; then, the second acceleration line corresponding to the combined acceleration data can be determined. Specifically, the method for obtaining the second acceleration line can be the same as the method for obtaining the first acceleration line, which will not be repeated here.

[0056] Furthermore, the maximum combined acceleration corresponding to the combined acceleration data and the third slope corresponding to the second acceleration line can be determined. Specifically, the maximum value in the combined acceleration data, that is, the maximum combined acceleration, can be found. Then, the third straight line equation corresponding to the second acceleration line can be obtained, and the third slope can be determined based on the third straight line equation; then, the combined angular velocity data corresponding to the three angular velocity data can also be determined. Specifically, the method for obtaining the combined angular velocity data can be the same as the method for obtaining the combined acceleration data, which will not be repeated here.

[0057] Then, the second angular velocity line corresponding to the combined angular velocity data can be determined. Specifically, the method for obtaining the second angular velocity line can be the same as the method for obtaining the first angular velocity line, which will not be repeated here; then, the maximum combined angular velocity corresponding to the combined angular velocity data and the fourth slope corresponding to the second angular velocity line can be determined. Specifically, the maximum value in the combined angular velocity data, that is, the maximum combined angular velocity, can be found. Then, the fourth straight line equation corresponding to the second angular velocity line can be obtained, and the fourth slope can be determined based on the fourth straight line equation; finally, the target detection result can be determined based on the maximum combined acceleration, the third slope, the maximum combined angular velocity and the fourth slope.

[0058] In this way, by synthesizing the three linear acceleration data (angular velocity data), the combined acceleration data (combined angular velocity data) is obtained, which integrates the linear motion intensity (rotational intensity) of the X, Y, and Z axes, avoiding missed judgments caused by "single-axis data does not exceed the standard but multi-axis superposition is severe."

[0059] Optional, see Figure 6 , Figure 6 is a flowchart of another method for determining target detection results provided by an embodiment of the present application, step D7, determining the target detection result according to the maximum combined acceleration, the third slope, the maximum combined angular velocity and the fourth slope, may include Figure 6 Steps shown: E1. When the maximum combined acceleration is greater than the first preset linear acceleration, and / or the maximum combined angular velocity is greater than the first preset angular velocity, determining that the target detection result includes that the mailbox door is opened; E2. When the maximum resultant acceleration is not greater than the first preset linear acceleration, and the maximum resultant angular velocity is not greater than the first preset angular velocity, obtaining a target motion duration corresponding to the target motion data; E3. Determine the total target rotation angle according to the target motion duration and the second angular velocity line; E4. If the total rotation angle of the target is greater than a preset rotation angle, determining that the target detection result includes that the mailbox door is open; E5. If the target total rotation angle is not greater than the preset rotation angle, determining an average combined angular velocity corresponding to the combined angular velocity data; and determining a third time length based on the target total rotation angle, the average combined angular velocity, and the preset rotation angle. E6. If the third time length is greater than the preset time length, determining that the target detection result includes that the mailbox door is not opened; E7. If the third time length is not greater than the preset time length, determine that the target detection result includes that the mailbox door is opened.

[0060] In the embodiment of the present application, the preset rotation angle may be preset in advance or defaulted, for example, the preset rotation angle may be 60 degrees.

[0061] In a specific embodiment, when the maximum resultant acceleration is greater than the first preset linear acceleration, and / or the maximum resultant angular velocity is greater than the first preset angular velocity, it indicates that the mailbox door is subjected to a large thrust or impact force, causing the door to move from a stationary state to a moving state in a short period of time and will soon be opened. In this case, it can be determined that the target detection result includes that the mailbox door is opened; When the maximum resultant acceleration is not greater than the first preset linear acceleration, and the maximum resultant angular velocity is not greater than the first preset angular velocity, the target motion duration corresponding to the target motion data can be obtained. Specifically, the acquisition time of each data in the target motion data can be obtained first, and multiple acquisition times can be obtained. The earliest time and the latest time among the multiple acquisition times are determined, and the target motion duration can be obtained by subtracting the earliest time from the latest time. Then, the target total rotation angle can be determined according to the target motion duration and the second angular velocity straight line. Specifically, the second angular velocity straight line can be integrated within the target motion duration to obtain the target total rotation angle. If the target total rotation angle is greater than the preset rotation angle, it is determined that the target detection result includes that the mailbox door is open.

[0062] If the target total rotation angle is not greater than the preset rotation angle, the average value of the combined angular velocity data, that is, the average combined angular velocity, can be calculated; then, the third time length can be determined based on the target total rotation angle, the average combined angular velocity and the preset rotation angle. Specifically, the target total rotation angle can be subtracted from the preset rotation angle to obtain the target angle difference, and then the target angle difference can be divided by the average combined angular velocity to obtain the third time length; if the third time length is greater than the preset time length, it is determined that the target detection result includes that the mailbox door is not open.

[0063] If the third time length is not greater than the preset time length, it is determined that the target detection result includes that the mailbox door is opened.

[0064] In this way, when the maximum combined acceleration (maximum combined angular velocity) exceeds the first preset linear acceleration (first preset angular velocity), the door is directly judged to be open. Otherwise, whether the door is open is judged based on the target total rotation angle and the preset rotation angle. If the target total rotation angle is greater than the preset rotation angle, the door is judged to be open. If the target total rotation angle is not greater than the preset rotation angle, the door is judged to be not open, filtering out "meaningless small shakes", thereby improving the accuracy of the judgment.

[0065] S404: When the target detection result includes that the mailbox door is opened, obtain the second mailbox internal information of the target mailbox.

[0066] In an embodiment of the present application, when the target detection result includes that the mailbox door is open, the internal information of the second mailbox of the target mailbox can be obtained. Specifically, the method for obtaining the internal information of the second mailbox can be the same as the method for obtaining the internal information of the first mailbox, which will not be repeated here.

[0067] S405: Determine target alarm information according to the internal information of the first mailbox and the internal information of the second mailbox.

[0068] In the embodiment of the present application, the difference information between the internal information of the first mailbox and the internal information of the second mailbox can be determined, and the target alarm information can be determined based on the difference information.

[0069] Optionally, the first mailbox internal information includes: the first mail quantity, the first door opening duration, and the first environmental data; the second mailbox internal information includes: the second mail quantity, the second door opening duration, and the second environmental data; and determining the target alarm information based on the first mailbox internal information and the second mailbox internal information may include the following steps: S51. Determine the difference between the second number of mail items and the first number of mail items to obtain a target number difference; S52. Determine a first anomaly score corresponding to the target quantity difference; S53: Determine the difference between the second door opening duration and the first door opening duration to obtain a target duration difference; S54, determining a second anomaly score corresponding to the target duration difference; S55. Determine a third anomaly score based on the first anomaly score and the second anomaly score; S56. Determine the deviation between the second environmental data and the first environmental data to obtain a target deviation; S57, determining a target adjustment coefficient corresponding to the target deviation; S58. Adjust the third anomaly score according to the target adjustment coefficient to obtain a target anomaly score; S59: Determine a target anomaly level corresponding to the target anomaly score; S510: Determine the target alarm information corresponding to the target abnormality level.

[0070] In the embodiment of the present application, the anomaly score represents a quantitative indicator of the anomaly of the target mailbox. The value range of the anomaly score can be 0~10, where the higher the anomaly score, the greater the possibility that the target mailbox has an anomaly (for example, emails are stolen).

[0071] In a specific embodiment, the target quantity difference can be obtained by subtracting the first quantity of mails from the second quantity of mails; then, the first anomaly score corresponding to the target quantity difference can be determined. For example, a mapping relationship between a preset quantity difference and anomaly score can be pre-stored, and the first anomaly score corresponding to the target quantity difference can be determined based on the mapping relationship; then, the target duration difference can be obtained by subtracting the first door opening duration from the second door opening duration; then, the second anomaly score corresponding to the target duration difference can be determined. Similarly, a mapping relationship between a preset duration difference and anomaly score can be pre-stored, and the second anomaly score corresponding to the target duration difference can be determined based on the mapping relationship.

[0072] Furthermore, a third anomaly score can be determined based on the first anomaly score and the second anomaly score. Specifically, the first anomaly score and the second anomaly score can be directly added to obtain the third anomaly score. Alternatively, a first weight (e.g., 0.7) corresponding to the first anomaly score and a second weight (e.g., 0.3) corresponding to the second anomaly score can be determined, and the sum of the first weight and the second weight is 1. A weighted operation is performed based on the first anomaly score, the second anomaly score, the first weight, and the second weight to obtain the third anomaly score. Then, the deviation between the second environment data and the first environment data can be determined as follows: Target deviation = (second environment data - first environment data) / first environment data × 100%; According to the above formula, the target deviation can be obtained; then, the target adjustment coefficient corresponding to the target deviation can be determined. Specifically, a mapping relationship between a preset deviation and an adjustment coefficient can be pre-stored, and the target adjustment coefficient corresponding to the target deviation can be determined based on the mapping relationship, wherein the target adjustment coefficient can range from 0 to 0.15; then, the third anomaly score can be adjusted according to the target adjustment coefficient, as follows: Target anomaly score = third anomaly score × (1 + target adjustment coefficient); According to the above formula, the target anomaly score can be obtained; then, the target anomaly level corresponding to the target anomaly score can be determined. Specifically, the target anomaly level can be determined according to the size of the target anomaly score. For example, when the target anomaly score is between 0 and 3, the corresponding target anomaly level is a low anomaly level. When the target anomaly score is between 4 and 7, the corresponding target anomaly level is a medium anomaly level. When the target anomaly score is between 8 and 10, the corresponding target anomaly level is a high anomaly level. Finally, the target alarm information corresponding to the target anomaly level can be determined. Specifically, the corresponding target alarm information can be generated according to the level of the target anomaly level. The mapping relationship between the preset anomaly level and the alarm information can be pre-stored, and the target alarm information corresponding to the target anomaly level can be determined based on the mapping relationship.

[0073] S406: Send the target alarm information to the administrator via the communication module to ensure mailbox security.

[0074] In an embodiment of the present application, the target alarm information can be sent in the form of text messages, emails, mobile phone pop-ups, voice prompts, etc. The communication module sends the target alarm information to the management personnel to prompt the management personnel to conduct a security check on the target mailbox, thereby ensuring the safety of the mailbox. For example, the target alarm information can be "[xx Community Smart Mailbox Warning] An abnormality occurred in the mailbox No. x in Building x at x time: 2 items were reduced after the door was opened, suspected of being stolen. Please go and check immediately."

[0075] It can be seen that the mailbox alarm method described in this application first confirms whether the mailbox door is open through a six-axis sensor, and then compares the difference in internal information before and after the door is opened to determine whether there is an abnormality (such as mail theft, foreign objects intrusion, etc.). After confirming the existence of the abnormality, an early warning operation is performed through the communication module, thereby realizing the abnormal alarm function of the mailbox.
