When installing the sensor, installation and maintenance personnel need to use professional tools to obtain information such as the height and angle of the sensor in order to calibrate and adapt the sensing signal so that the perceived target information is accurate and consistent at different installation heights and angles. . For example, sensors usually include recommended heights and angles when they leave the factory. Users can also set the desired height and angle according to actual usage needs.

S610, obtain the first angle.

Specifically, the angle measuring device 511 in the sensor is used to obtain the first angle, or in other words, to measure the first angle.

The first angle includes the angular change amount of the current position of the sensor relative to the preset position, or the first angle may also include the angular change direction of the sensor. For example, the first angle may be 30° north by west.

In some embodiments, the preset position is located in a coordinate system composed of a first coordinate axis, a second coordinate axis, and a third coordinate axis, and the first coordinate axis, the second coordinate axis, and the third coordinate axis are in pairs. vertical. The first coordinate axis may be the x-axis of the coordinate system shown in Figure 7, the second coordinate axis may be the y-axis of the coordinate system shown in Figure 7, and the third coordinate axis may be the z-axis of the coordinate system shown in Figure 7 . The current position is located in the coordinate system composed of the fourth coordinate axis, the fifth coordinate axis and the sixth coordinate axis. The fourth coordinate axis can be the x' axis in the coordinate system shown in Figure 7, and the fifth coordinate axis can be The sixth coordinate axis may be the y′ axis in the coordinate system shown in FIG. 7 , and the sixth coordinate axis may be the z′ axis in the coordinate system shown in FIG. 7 . When the sensor only changes in angle, the origin of the x'y'z' coordinate system is the same as the xyz coordinate system.

The first angle may include at least one of a first angular component, a second angular component and a third angular component. The first angular component is an angular change amount of the fourth coordinate axis relative to the first coordinate axis, and also It is the angular change α ₁ of the x′ axis relative to the x axis. The second angular component is the angular change of the fifth coordinate axis relative to the second coordinate axis, that is, the angular change of the y′ axis relative to the y axis. The _third angular component is the angular change amount of the sixth coordinate axis relative to the third coordinate axis, that is, the angular change amount γ ₃ of the z′ axis relative to the z axis, as shown in Figure 7 .

It should be understood that when the angle of the sensor changes, if the x' axis rotates relative to the x axis, the y' axis and/or z' will also rotate accordingly. That is to say, at the rotated position, α ₁ , β ₂ and γ ₃ are determined angles. Furthermore, the sensor can adjust the angle of the sensor at the current position to be the same as the angle at the preset position according to the sizes of α ₁ , β ₂ and γ ₃ .

In some embodiments, the angle measurement device 511 in the sensor can measure the angular rotation amount of each of the three coordinate axes, that is, the difference between each coordinate axis of the coordinate system where the current position is located and each coordinate axis of the coordinate system where the preset position is located. angle, as shown in Table 1.

Table 1

In some embodiments, before the sensor acquires the first angle, the method may further include: determining a preset position, the preset position being an initial position for installation of the sensor.

The preset position, or the xyz coordinate system, can be determined by the angle measuring device 511 in the sensor. For example, when the sensor is fixed on the wall, the fixed position can be set as the origin, the wall height direction is the z-axis direction, the connection position between the wall and the ground is the x-axis direction, and the xOy plane is parallel to the ground.

The angle of the preset position can be the spatial angle of the body 510 at the preset position. For example, it can be represented by the pitch angle of the body 510 with the xOy plane, and the angle with the xOz or yOz plane. When the angle of the sensor changes, the angle of the preset position can be regarded as 0° to determine the deflection of the angle.

S620: According to the first angle, adjust the angle of the current position to be the same as the angle of the preset position.

The sensor includes a main chip, that is, a processor. The processor is connected to the angle measurement device 511. The processor can obtain the first angle from the angle measurement device 511. The processor is connected to the angle measurement device 511. The connection method can be BT connection or WiFi connection.

The sensor also includes an adjustment device, which is connected to the processor. The adjustment device can be a motor. The connection between the adjustment device and the processor can be a BT connection or a WiFi connection. After the processor obtains the first angle from the angle measurement device 511, it sends the first angle to the adjustment device. According to the first angle, the adjustment device drives the sensor to adjust the angle of the current position to be consistent with the preset angle. The angle of the position is the same.

In some embodiments, the processor may also send instruction information to the adjustment device to instruct the adjustment device to perform angle adjustment.

In some embodiments, adjusting the angle of the current position to the same angle as the preset position according to the first angle includes: according to at least one of the first angular component, the second angular component and the third angular component. One item, adjust the angle of the current position to be the same as the angle of the preset position. The sensor can automatically sense and measure the angle changes of the three coordinate axes, and adjust the angle of the sensor at the current position to be the same as the angle of the preset position based on the angle change amount and direction of the three coordinate axes.

Specifically, the adjustment device is used to adjust the angle of the current position to be the same as the angle of the preset position according to at least one of the first angular component, the second angular component and the third angular component.

Based on the solution provided by this application, the sensor can automatically sense and measure the change of the angle of the current position relative to the angle of the preset position, and according to the change, rotate the angle of the sensor or the angle of the sensor body 510 to The same angle as the original position.

In some embodiments, the method further includes: sending first notification information, the first notification information being used to indicate that the angle of the sensor changes. The sensor can send the first notification information to the paired electronic device to facilitate the user to learn the angle change and adjustment of the sensor. The alarm device of the sensor can also send alarm information to the outside world, that is, the first notification information, such as a flashing indicator light or an alarm sound prompt, etc. to inform the user of the angle change and adjustment of the sensor.

Specifically, the processor may send the first notification information to the paired electronic device, or the processor may send the first notification information to the alarm device, and the alarm device forwards the first notification information to the outside world. The processor may also send instruction information to the alarm device to instruct the alarm device to alarm, that is, forward the first notification information.

In some embodiments, the first notification information is also used to indicate at least one of the first angle component, the second angle component and the third angle component.

In some embodiments, the method further includes: obtaining a first distance, where the first distance is the current position of the sensor relative to the preset distance. Set the distance change of the position.

Specifically, the distance measuring device 541 obtains the first distance.

During the use of the sensor, the position of the sensor may deviate from the original fixed position due to collision, that is, the current position changes in distance relative to the preset position. The distance measuring device 541 in the sensor can sense and measure the distance. Amount and direction of change.

In some embodiments, the first distance includes at least one of a first distance component, a second distance component, and a third distance component, and the first distance component is from the current position of the sensor to the first coordinate axis and the first coordinate axis. The distance from the plane formed by the second coordinate axis. The second distance component is the distance from the current position of the sensor to the plane formed by the first coordinate axis and the third coordinate axis. The third distance component is the distance between the sensor and the plane formed by the first coordinate axis and the third coordinate axis. The distance from the current position to the plane formed by the second coordinate axis and the third coordinate axis.

When the distance of the sensor changes, the coordinate system of the current position of the sensor can be the x"y"z" coordinate system as shown in Figure 8, and the origin O" can be the base 540 of the sensor after the distance of the sensor changes. location. The first distance component may be the distance from the coordinate origin O″ of the current position to the plane of the coordinate system xOy of the preset position, and the second distance component may be the distance from the coordinate origin O″ of the current position to the coordinate system of the preset position. The distance on the plane where xOz is located, the third distance component can be the distance from the coordinate origin O″ of the current position to the plane on which the coordinate system yOz is located at the preset position. The first distance component, the second distance component and the third distance component are also The direction in which the distance changes may be included. For example, when the magnitude of the first distance component is a negative value, it may mean that the position of the sensor moves in the negative direction of the z-axis.

It should be understood that when the angle and distance of the sensor change, the magnitudes of the first angular component, the second angular component and the third angular component of the sensor are still the angle between the x" axis and the x axis, y" respectively. The angle between the x-axis and the y-axis, the angle between the z″-axis and the z-axis, is equivalent to moving x″y″z″ back to the original x′y′z′ position, which is the angle between the x′-axis and the x-axis, y The angle between the ′ axis and the y axis, and the angle between the z′ axis and the z axis. The angle measuring device 511 can automatically measure the angle between the x″ axis and the x axis, the angle between the y″ axis and the y axis, and the angle between the z″ axis and the z axis.

In some embodiments, the method further includes: sending second notification information, the second notification information being used to indicate at least one of the first distance component, the second distance component and the third distance component. The first distance component may include the direction of the distance change, for example, the positive or negative value of the distance indicates the positive or negative movement of the sensor's position along the coordinate axis.

The sensor can send the second notification information to the paired electronic device, and the user can directly check the distance change of the sensor on the electronic device, or the alarm device of the sensor can send alarm information, that is, the second notification, to the outside world. Information to inform the user of the change in distance of the sensor so that the user can adjust the fixed position of the sensor.

Specifically, the distance measurement device 541 is connected to the processor. After the distance measurement device 541 obtains the first distance, the distance measurement device 541 sends the first distance to the processor. The processor communicates with the distance The connection mode of the measurement device 541 may be a BT connection or a WiFi connection. The processor sends the second notification information to the paired electronic device, or the processor sends the second notification information to the alarm device, and the alarm device forwards the second notification information to the outside world. The processor may also send instruction information to the alarm device to instruct the alarm device to issue an alarm, that is, forward the second notification information.

Through the embodiments provided by this application, the sensor can sense its own angle and distance changes at all times. When the angle changes, it automatically adjusts the angle of the current position to the same angle as the preset position, thereby ensuring the accuracy of the measurement signal before and after the angle change. Accurate and consistent. When the distance changes, the user is instructed to adjust the position of the sensor through notification information.

Based on the sensor provided by the embodiment of the present application, it can also reduce the difficulty for users to install the sensor. When the user installs the sensor, the distance measuring device 541 and the angle measuring device 511 in the sensor can directly measure the height and angle of different positions and prompt the user to facilitate the user to determine the appropriate installation position. Alternatively, the sensor can include different height and angle gears. The user can select the appropriate gear according to actual needs, and measure and sense whether the user has installed the sensor at the desired location through the angle measuring device 511 and the distance measuring device 541. Select the corresponding position of the gear, and the user can install the sensor without using professional calibration tools.

The method described in Figures 6 to 8 is to use the angle measurement device 511 in the sensor to measure the rotation angles of the three coordinate axes in the coordinate system where the preset position is located, and to measure the sensor based on the rotation angles of the three coordinate axes. Angle is carried out. The following is an adaptation method of the sensor angle provided by this application in conjunction with Figure 9. When the angle of the sensor changes, the sensor can adjust the angle of the sensor according to the pitch angle of the target relative to the sensor and the coordinate system of the original position. The angle is adjusted by the angle between the y-axes.

As shown in Figure 9, the sensor can be used to measure the position of a target such as a human body.

For example, the sensor can be fixed on the wall. Assume that a three-axis coordinate system is established with the perpendicular foot of the sensor to the ground as the origin. The straight line where the perpendicular line of the sensor to the ground is located is the z-axis, and the intersection line between the wall and the ground is The x-axis and the y-axis are the coordinate axes perpendicular to the xOz plane.

The distance measuring device 541 located in the base 540 can measure the distance d between the base 540, that is, the sensor device and the ground, and the straight-line distance r from the human body. The angle measuring device 511 located in the body 510 can measure the distance between the target object and the human body. The pitch angle θ of the sensor is the angle between the line between the target and the sensor and the xOy plane, as well as the line between the vertical foot of the sensor on the xOy plane and the vertical foot of the target on the xOy plane. The angle between the y-axes

Assuming that the position of the target is (x ₀ , y ₀ , z ₀ ), z ₀ is the height of the target, then the position of the target can be calculated by the following formula:
z ₁ =r·sinθ (1)


z ₀ =dz ₁ (4)

Among them, z ₁ is the height difference between the target object and the sensor. When the installation height d of the sensor is lower than the height of the target object z ₀ , z ₀ =d+z ₁ , thus calculating the position of the target object ( x ₀ , y ₀ , z ₀ ).

When the angle of the sensor changes, the above angle θ and will change accordingly as the angle of the sensor changes. The angle change of the sensor is still explained using the coordinate system shown in Figure 7. x′y′z′ is the coordinate system where the sensor is located after rotation.

As shown in Table 1 above, assuming that the coordinate axes of the coordinate system where the sensor is rotated are x', y' and z' respectively, the angle measuring device 511 in the body 510 can respectively measure the rotated coordinate axes and The angle between the original coordinate axes: the angle between the x′ axis and the x axis is α ₁ , the angle between the x axis and the y axis is β ₁ , and the angle between the z axis and the z axis is γ ₁ ; the angle between the y′ axis and the x axis The angle between is α ₂ , the angle between it and the y-axis is β ₂ , and the angle between it and the z-axis is γ ₂ ; the angle between the z′-axis and the x-axis is α ₃ , and the angle between it and the y-axis is β ₃ , the angle with the z-axis is γ ₃ . Then the conversion relationship between the rotated coordinate system x′y′z′ and the original coordinate system xyz can be expressed by the following formulas (5), (6) and (7):
x′＝x·cosα ₁ +y·cosβ ₁ +z·cosγ ₁ (5)
y′＝x·cosα ₂ +y·cosβ ₂ +z·cosγ ₂ (6)
z′＝x·cosα ₃ +y·cosβ ₃ +z·cosγ ₃ (7)

The position of the target object has been measured in the original coordinate system, that is, x ₀ , y ₀ , z ₀ and z ₁ are known numbers. Combined with formula (1), that is, in the rotated coordinate system, the The pitch angle of the target relative to the sensor is θ′, as shown in equation (8):
θ′＝arcsinz′/r (8)

It should be understood that when the angle of the sensor changes, if the reference object does not shift, the distance between the sensor and the reference object is regarded as unchanged.

Similarly, combined with the above formula (2), the angle between the reference object and the y-axis of the sensor is The size of is shown in equation (9):

Then Δθ=arcsinz′/r–θ (10)

The θ and and the angle between each coordinate axis, and send them to the SoC for calibration. That is to say, the SoC can perform the calculations of the above formulas (1) to (11) and send instruction information to the adjustment device, instructing the adjustment device according to Δθ and Adjust the angle of the sensor. Alternatively, the angle measurement device 511 and/or the distance measurement device 541 may also perform the calculation of the above formula. For example, the distance measurement device 541 performs the calculation of the target position, that is, performs the calculation of the above formulas (1) to (4). , the angle measuring device 511 performs the calculation of the coordinate system conversion and the calculation of the angle that needs to be adjusted, that is, the calculation of the above equations (5) to (11) is performed. The distance measuring device 541 and the angle measuring device 511 may be connected through a BT connection or a WiFi connection for transmitting angle and distance measurement results and other information.

Based on the embodiments provided by this application, adding an angle measurement device 511 and a distance measurement device 541 to a sensor, such as a human body sensor, can automatically sense the angle and distance changes of the current position relative to the preset position, and detect changes in the angle when the angle changes. It automatically adjusts its own angle at any time to ensure the accuracy and consistency of the measurement signal before and after the angle changes. Using the sensor provided by this application can also reduce the difficulty of sensor installation.
