[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that, if not conflicted, the various features of the embodiments of the invention may be combined with each other within the scope of protection of the invention. Additionally, while functional block divisions are performed in the device diagrams, with logical sequences shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than the block divisions in the device diagrams, or the flowcharts.

The remote control device in the embodiment of the invention comprises a remote control body and a Hall rocker. The Hall rocker is fixed on the remote control body and is used for a user to operate so as to input a remote control command to the remote control device. The number of the Hall rockers can be set according to the requirement, such as one, two or more. In this embodiment, the remote control device includes two hall rockers. The two Hall rockers are respectively a left Hall rocker and a right Hall rocker, so that the left hand and the right hand of a user can operate respectively or simultaneously conveniently.

Wherein, as shown in fig. 1, each hall rocker includes: hall chip 100, magnet 200, and rocker 300. The hall chip 100 is fixed to the remote control device, and the magnet 200 is fixed to the rocker 300, as shown in fig. 2, when the rocker 300 is toggled, the magnet is driven to change according to a limited angle, and the angle range is limited according to the structure of the rocker.

In this embodiment, as shown in FIG. 3, when the Hall rocker is stationary, the Hall rocker is in a neutral position, maintaining a median value. The left area and the right area of the Hall rocker are filled with a maximum angle value and a minimum angle value which can respectively reach the transverse direction; the upper area and the lower area of the Hall rocker are filled with the liquid, and the maximum angle value and the minimum angle value in the longitudinal direction can be respectively reached. The maximum angle value or the minimum angle value corresponding to full left or full right, and the maximum angle value or the minimum angle value corresponding to full up or full down are not limited herein. For example, the maximum angle value corresponding to the transverse direction is set to be full to the right, and the minimum angle value corresponding to the transverse direction is set to be full to the left; and setting the maximum angle value which is fully filled upwards and corresponds to the longitudinal direction, and fully filling the minimum angle value which corresponds to the longitudinal direction downwards.

In this embodiment, the remote control device may be used to control devices such as drones, unmanned vehicles, and the like. A rocker calibration method is given below based on a hall rocker of the remote control. As shown in fig. 4, the method includes:

and step S11, acquiring the sampling parameters of the target point when the rocker is in the calibration mode.

The calibration mode refers to a mode of operation for determining the hall rocker indication error. The calibration mode may be triggered by the user actively turning on the calibration mode, for example, the user inputs a calibration mode command by voice, or inputs a calibration mode command on a touch screen of the remote control device by a finger, a stylus pen, or the like, or inputs a calibration mode command by pressing a button on the remote control device, or the like, thereby turning on the calibration mode. The calibration mode may be triggered by automatically entering the calibration mode according to a preset condition. For example, when the remote control device is used for the first time, the remote control device is in the calibration mode because the calibration parameters are not stored in the memory of the remote control device. Or, when the remote control device is powered on, whether the calibration parameters stored in the memory can be used or not can be detected, and if the calibration parameters cannot be used, the calibration mode is automatically entered. Or, when the remote control device is turned on, judging whether the hall rocker is at a preset position (such as a middle position), and when detecting that the hall rocker is not at the preset position within n seconds, automatically performing a calibration mode, wherein n can be any numerical value.

The target points refer to points for determining calibration parameters of the hall rocker, which are in particular points of a specific position determined according to the structure of the hall rocker.

For example, according to the working range of the hall rocker shown in fig. 3, it can be determined that the target points include 9 singular points as shown in fig. 5, where 0 point is a median point, 2, 4, 6, and 8 points are diagonal points, and 1, 3, 5, and 7 points are edge points. The median point is a point corresponding to the middle position of the Hall rocker. In this embodiment, these 9 singularities need to be sampled.

Acquiring the sampling parameters of the target point, namely, performing parameter sampling on the target point. Specifically, as shown in fig. 6, acquiring the sampling parameters of the target point includes:

step S111, controlling the rocker to move to the target point;

specifically, the user can control the rocker to move to the target point, and the remote control device detects whether the rocker is at the target point.

Step S112, calculating a transverse angle value alpha and a longitudinal angle value beta corresponding to the target point, wherein the transverse angle value alpha and the longitudinal angle value beta are sampling parameters of the target point;

wherein, theThe above-mentioned

Wherein, said m_x、m_y、m_zMagnetic flux of x, y and z axes output by the chip, k_a、k_b、k_tIs preset adjustable parameters.

In this embodiment, each target point includes sampling parameters in both the transverse direction and the longitudinal direction, and obtaining the sampling parameters in both the transverse direction and the longitudinal direction is to obtain an angle value, i.e., a transverse angle value and a longitudinal angle value, of the hall rocker poking in both the transverse direction and the longitudinal direction. The transverse angle value alpha and the longitudinal angle value beta may be calculated according to the above formula. The prior art can be referred to the principle of calculating the alpha and the beta according to the formula.

Wherein, the transverse angle value alpha and the longitudinal angle value beta corresponding to the target point include: the horizontal angle value alpha (0) and the longitudinal angle value beta (0) corresponding to the median point 0, the horizontal angle value alpha (2/4/6/8) and the longitudinal angle value beta (2/4/6/8) corresponding to the diagonal point 2/4/6/8, and the horizontal angle value alpha (1/3/5/7) and the longitudinal angle value beta (1/3/5/7) corresponding to the sideline point 1/3/5/7.

In order to have a more accurate sampling of the target point, in some embodiments, as shown in fig. 7, the method further comprises:

step S113, respectively sampling the transverse angle value alpha and the longitudinal angle value beta of the target point for preset times; the preset times can be customized by a user.

Step S114, calculating the average value of the transverse angle value alpha of the preset times and the average value of the longitudinal angle value beta of the preset times, wherein the average value of the transverse angle value alpha and the average value of the longitudinal angle value beta are sampling parameters of the target point.

In this embodiment, the finally obtained transverse angle value alpha and longitudinal angle value beta of the target point are average values of sampling values, so that the sampling precision of the target point is improved, and the accuracy of subsequently obtained calibration parameters is also improved.

And step S12, acquiring the maximum poking angle value of the rocker.

The maximum angle value refers to the maximum angle to which the rocker is shifted, the shifting position of the rocker is not limited, and the rocker can be in any direction of four directions, namely up, down, left and right. Since the structure of the hall rocker is fixed, there is no need to distinguish the direction in which the rocker is toggled, since the maximum angle to which the rocker is toggled in each direction is the same.

In this embodiment, an operation prompt message prompting the user to dial the rocker may be sent to the user, for example, the operation prompt message is broadcast by the remote control device in a voice broadcast manner, or the operation prompt message is sent by the remote control device on a display screen. And after the user finishes the operation of poking the rocker to the maximum angle, the remote control device acquires the maximum angle value.

In some embodiments, a maximum angle value of the rocker toggle, such as the last detected maximum angle value, may be pre-saved in the remote control device. So that the maximum angle value can be retrieved directly from memory. The pre-saved maximum angle value may be stored in the remote control device, or may be stored in a cloud server.

And step S13, calculating the calibration parameters of the target point according to the sampling parameters and the maximum angle value.

In this embodiment, the target points include a median point, a diagonal point, and an edge point. The specific steps of calculating the calibration parameters of the target points according to the sampling parameters and the maximum angle values are specifically described with reference to the horizontal left axis and the vertical left axis according to the position distribution of the target points in fig. 5.

Wherein, the calibration parameter of the median point in the transverse direction and the calibration parameter in the longitudinal direction are both fixed to be 1. Of course, in practical applications, the calibration parameter of the middle point may also be set to other values.

When the target point is a diagonal point, as shown in fig. 8, the calculating the calibration parameter of the target point according to the sampling parameter and the maximum angle value includes:

step S210, carrying out difference calculation on the transverse angle value of the diagonal point and the transverse angle value of the median point to obtain a first difference value;

step S220, carrying out difference calculation on the longitudinal angle value of the diagonal point and the longitudinal angle value of the median point to obtain a second difference value;

step S230, performing a quotient calculation on the maximum angle value, the first difference value and the second difference value respectively to obtain a first quotient value and a second quotient value, where the first quotient value is a calibration parameter of the diagonal point in the transverse direction, and the second quotient value is a calibration parameter of the diagonal point in the longitudinal direction.

The four diagonal points 2, 4, 6, 8 in fig. 5 may all be used to obtain their respective calibration parameters in the transverse direction and the longitudinal direction.

Wherein the edge points include horizontal axis edge points (such as point 1 and point 5) and vertical axis edge points (such as point 3 and point 7). When the target point is a horizontal axis edge point, as shown in fig. 9, the calculating the calibration parameter of the target point according to the sampling parameter and the maximum angle value includes:

step S310, carrying out difference calculation on the transverse angle value of the sideline point of the transverse axis and the transverse angle value of the median point to obtain a third difference value;

step S320, performing a quotient operation on the maximum angle value and the third difference value, and generating a calibration parameter of the horizontal axis sideline point in the horizontal direction.

And the calibration parameter of the horizontal axis sideline point in the longitudinal direction is 1. In practical applications, the calibration parameter of the horizontal axis edge point in the longitudinal direction may also be set to other values.

When the target point is a longitudinal axis edge point, as shown in fig. 10, the calculating the calibration parameter of the target point according to the sampling parameter and the maximum angle value includes:

step S410, carrying out difference calculation on the longitudinal angle value of the longitudinal axis sideline point and the longitudinal angle value of the median point to obtain a fourth difference value;

step S420, performing a quotient operation on the maximum angle value and the fourth difference value, and generating a calibration parameter of the longitudinal axis edge point in the longitudinal direction.

Wherein the calibration parameter of the longitudinal axis edge point in the transverse direction is 1. In practical applications, the calibration parameter of the longitudinal axis edge point in the transverse direction may also be set to other values.

And step S14, calibrating the rocker according to the calibration parameters.

Calibrating the rocker according to the calibration parameters comprises: acquiring new parameters of the rocker according to the calibration parameters and the original parameters of the rocker; and converting the new parameters of the rocker into a rocker instruction, namely converting the data of the original data after the calibration parameter calculation into the rocker instruction of the remote control device for controlling other equipment, such as the rocker instruction for controlling the unmanned aerial vehicle.

In some embodiments, during the calibration of the joystick, an alarm message may be sent to prompt the user to pay attention to the current calibration mode.

In some embodiments, during the calibration of the joystick, the whole calibration process can be displayed on the remote control device, and a prompt message is sent after the calibration is completed.

The rocker calibration method described above is described in detail below as an example. For example, referring to fig. 5, the hall rocker is calibrated, i.e., the calibration parameters of 9 singularities in fig. 5 are obtained. Firstly, acquiring sampling parameters of the 9 singularities, namely (alpha _ bias (0), beta _ bias (0)), (alpha _ bias (1), beta _ bias (1)), (alpha _ bias (2), beta _ bias (2)), (alpha _ bias (3), beta _ bias (3)), (alpha _ bias (4), beta _ bias (4)), (alpha _ bias (5), beta _ bias (5)), (alpha _ bias (6), beta _ bias (6)), (alpha _ bias (7), beta _ bias (7)), (alpha _ bias (8) and beta _ bias (8)); then determining the maximum angle value as scope _ value;

the calibration parameters for calculating the diagonal points 2, 4, 6, and 8 are:

alpha_scale[2]＝scope_value/(alpha_bias(2)-alpha_bias(0))；beta_scale[2]＝scope_value/(beta_bias(2)-beta_bias(0))

alpha_scale[4]＝scope_value/(alpha_bias(4)-alpha_bias(0))；beta_scale[4]＝scope_value/(beta_bias(4)-beta_bias(0))

alpha_scale[6]＝scope_value/(alpha_bias(6)-alpha_bias(0))；beta_scale[6]＝scope_value/(beta_bias(6)-beta_bias(0))

alpha_scale[8]＝scope_value/(alpha_bias(8)-alpha_bias(0))；beta_scale[8]＝scope_value/(beta_bias(8)-beta_bias(0))

the calibration parameters for calculating the edge points 1, 3, 5, and 7 are:

alpha_scale[1]＝scope_value/(alpha_bias(1)-alpha_bias(0))；beta_scale[1]＝1

alpha_scale[3]＝1；beta_scale[3]＝scope_value/(alpha_bias(3)-alpha_bias(0))

alpha_scale[5]＝scope_value/(alpha_bias(5)-alpha_bias(0))；beta_scale[5]＝1

alpha_scale[7]＝1；beta_scale[7]＝scope_value/(alpha_bias(7)-alpha_bias(0))

the calibration parameters for the median point 0 are: alpha _ scale [0] ═ 1; beta _ scale [0] is 1.

In some embodiments, as shown in fig. 11, fig. 11 differs from fig. 4 primarily in that the method further comprises:

and step S15, dividing the target point into sectors according to the position of the target point.

The dividing the target point into sectors according to the position of the target point specifically is to divide a total area where the target point is located into a plurality of sub-areas, the areas of the sub-areas may be the same, and each sub-area includes the same number of target points. For example, as shown in fig. 12, 13, and 14, the sectors may be divided as shown in fig. 12, 13, and 14, but the present invention is not limited to fig. 12, 13, and 14.

And step S16, calculating calibration parameters of the sector according to the divided sector and the calibration parameters of the target point.

Wherein, the calculating the calibration parameters of the sector according to the divided calibration parameters of the sector and the target point comprises: determining a target point corresponding to the sector; and carrying out averaging operation on the calibration parameters of the target points corresponding to the sectors to generate the calibration parameters of the sectors.

For example, as shown in fig. 12, four sectors are divided, and in the horizontal direction, the calibration parameter of the first sector is sector _ alpha _ scale [1] (alpha _ scale [1] + alpha _ scale [2] + alpha _ scale [8 ])/3; the calibration parameter of the second sector is sector _ alpha _ scale [2] (alpha _ scale [2] + alpha _ scale [3] + alpha _ scale [4 ])/3; the calibration parameter of the third sector is sector _ alpha _ scale [3] (alpha _ scale [4] + alpha _ scale [5] + alpha _ scale [6 ])/3; the calibration parameter for the fourth sector is sector _ alpha _ scale [4] (alpha _ scale [6] + alpha _ scale [7] + alpha _ scale [8 ])/3. In the longitudinal direction, the calibration parameter of the first sector is sector _ beta _ scale [1] - (beta _ scale [1] + beta _ scale [2] + beta _ scale [8 ])/3; the calibration parameter for the second sector is sector _ beta _ scale [2] (beta _ scale [2] + beta _ scale [3] + beta _ scale [4 ])/3; the calibration parameter for the third sector is sector _ beta _ scale [3] (beta _ scale [4] + beta _ scale [5] + beta _ scale [6 ])/3; the calibration parameter for the fourth sector is sector _ beta _ scale [4] (beta _ scale [6] + beta _ scale [7] + beta _ scale [8 ])/3.

For example, as shown in fig. 13, eight sectors are divided, and in the horizontal direction, the calibration parameter of the first sector is sector _ alpha _ scale [1] (alpha _ scale [1] + alpha _ scale [2 ])/2; the calibration parameter for the second sector is sector _ alpha _ scale [2] (alpha _ scale [2] + alpha _ scale [3 ])/2; the calibration parameter of the third sector is sector _ alpha _ scale [3] (alpha _ scale [3] + alpha _ scale [4 ])/2; the calibration parameter for the fourth sector is sector _ alpha _ scale [4] (alpha _ scale [4] + alpha _ scale [5 ])/2; the calibration parameter for the fifth sector is sector _ alpha _ scale [5] (alpha _ scale [5] + alpha _ scale [6 ])/2; the calibration parameter for the sixth sector is sector _ alpha _ scale [6] (alpha _ scale [6] + alpha _ scale [7 ])/2; the calibration parameter for the seventh sector is sector _ alpha _ scale [7] - (alpha _ scale [7] + alpha _ scale [8 ])/2; the calibration parameter for the eighth sector is sector _ alpha _ scale [8] (alpha _ scale [8] + alpha _ scale [1 ])/2. In the longitudinal direction, the calibration parameter of the first sector is sector _ beta _ scale [1] (beta _ scale [1] + beta _ scale [2 ])/2; the calibration parameter for the second sector is sector _ beta _ scale [2] (beta _ scale [2] + beta _ scale [3 ])/2; the calibration parameter for the third sector is sector _ beta _ scale [3] (beta _ scale [3] + beta _ scale [4 ])/2; the calibration parameter for the fourth sector is sector _ beta _ scale [4] (beta _ scale [4] + beta _ scale [5 ])/2; the calibration parameter for the fifth sector is sector _ beta _ scale [5] (beta _ scale [5] + beta _ scale [6 ])/2; the calibration parameter for the sixth sector is sector _ beta _ scale [6] (beta _ scale [6] + beta _ scale [7 ])/2; the calibration parameter for the seventh sector is sector _ beta _ scale [7] - (beta _ scale [7] + beta _ scale [8 ])/2; the calibration parameter for the eighth sector is sector _ beta _ scale [8] (beta _ scale [8] + beta _ scale [1 ])/2.

For example, as shown in fig. 14, eight sectors are divided, and each sector corresponds to one singular point, i.e. several singular points 1 to 8, so when the sectors are divided in this way, the calibration parameter of the sector is the calibration parameter of each singular point, and reference can be specifically made to the above-mentioned embodiment.

And step S17, calibrating the rocker according to the calibration parameters of the sector.

According to the embodiment, the moving range of the rocker is divided into different sectors, and then the calibration parameters are obtained based on the sectors, so that the finally obtained calibration data is more accurate and stable due to the finer sector distribution.

The calibration parameters obtained in the above embodiment can be stored in the remote control device, and the calibration parameters can be directly used each time the remote control device is turned on. When the remote control device is used, the obtained three-axis magnetic flux data of the sensor Hall chip are calculated through the calibration parameters, integrated into a control instruction and then sent to a controlled device, such as an unmanned aerial vehicle, so that the controlled device is safely controlled.

The embodiment realizes the calibration function of the Hall rocker, has simple whole process, reduces the calibration complexity of the Hall rocker, is suitable for most remote control devices with the Hall rocker, and has stronger universality.
