In the description of the present invention, unless explicitly stated and defined otherwise, the step identifiers S101, S102, S103, etc. are used for convenience of description, and do not represent an execution sequence, and the corresponding execution sequence may be adjusted.

Example 1

Referring to fig. 1, a method for identifying the number of rope skipping includes:

s101, receiving an electric signal value detected by pressure sensing equipment, and acquiring the take-off time and the landing time according to the electric signal value; the pressure sensing equipment is arranged on the rope skipping pad;

s102, receiving an acceleration value detected by acceleration sensing equipment, and acquiring first time when the acceleration value exceeds an acceleration threshold value; the acceleration sensing equipment is arranged in the counterweight equipment connected with the handle;

s103, if the first time is in the time period between the take-off time and the landing time, increasing the rope skipping times by 1; the second time is a certain time before the landing time.

Specifically, the execution main body of the rope skipping frequency identification method comprises a main control module arranged on a rope skipping pad, wherein the main control module comprises a controller, and the controller is used for executing the rope skipping frequency identification method. In addition, S101 and S103 may be executed in a main control module on the rope skipping mat, and S102 may be executed in a cordless rope skipping apparatus.

In this embodiment, when the user jumps the rope on the rope-jumping pad, the jump and landing can both cause the pressure sensing device to change in pressure value or pressure state. Pressure sensing devices that may be used herein include membrane switches or carbon membrane spacers, which change resistance or state at both take off and landing, and ultimately convert to an electrical signal output. The main control module distinguishes the take-off and landing by sampling the electric signal value, correspondingly records the time of the take-off and landing, and records the number of times of rope skipping once when the process of taking-off and landing is completed once.

In the embodiment, when the pressure value suddenly decreases, the corresponding output electric signal value decreases, so as to judge the take-off action and the take-off time; correspondingly, at the moment when the pressure value suddenly increases, the corresponding output electric signal value increases, so that the landing action and the landing time are judged. It should be noted that, according to the specific pressure sensing device, the judging principle and method may be different, and the embodiment is not limited specifically.

When the acceleration sensing device is connected with the rope skipping pad in a wireless mode such as Bluetooth, position information can be transmitted. And the acceleration sensing equipment is arranged at a counterweight device (such as a counterweight small ball) connected with the handle, and acquires the acceleration value of each tiny moment (the specific sampling period can be set by the acceleration sensing equipment) in real time. The linear velocity and the angular velocity of the ball gradually decrease during upward movement, gradually increase during downward movement, and the values of the linear velocity and the angular velocity reach the maximum at the lowest point when the ball performs the variable-speed circular movement. In order to ensure that the centripetal force required by the circular motion of the ball is the maximum, and the acceleration value obtained by the acceleration sensing device is the result of the combined action of the centripetal force ensuring the circular motion and the gravity of the ball when the counterweight ball moves to the lowest point. Since the directions of the two directions are opposite, the acceleration value obtained by the acceleration sensing device at this time is the largest in the entire circular motion. The lowest point can be determined by setting an acceleration threshold.

According to the embodiment, the acceleration sensing equipment is arranged in the counterweight equipment connected with the handle, and meanwhile, data processing is carried out on the rope skipping pad, so that the structure of the handle is simplified, meanwhile, the influence of position change on the acceleration sensing equipment is more obvious, and the recognition accuracy is higher.

From the calculation formula f= 4*m pi of centripetal force ² *f ² * r and the stress analysis can prove that, in theory, the sum of the accelerations of the weight ball at the lowest points measured by the acceleration sensing device is a=g+4 pi ² *f ² * r, the acceleration threshold should be slightly greater than the calculated value due to the effect of jerk motion. When the acceleration value exceeds the acceleration threshold value, the minimum point is considered and information is sent, and the time of the minimum point is judged after calculation and correction of the rope skipping pad.

According to the above description, in this embodiment, the acceleration threshold is equal to the sum of the centripetal acceleration and the gravitational acceleration of the configuration module, i.e. a=g+4×pi ² *f ² * r. Wherein a represents an acceleration threshold; g represents gravitational acceleration; pi represents the circumference ratio; f represents the rotation frequency; r represents the length of the counterweight module pull wire.

According to the embodiment, the sum of the centripetal force acceleration value and the gravity acceleration value of the counterweight equipment at the lowest point is taken as an acceleration threshold value, the first time when the real-time acceleration value exceeds the acceleration threshold value is obtained in combination with the influence of jumping motion, and accurate rope jumping actions are identified by judging whether the first time is in a jumping time period.

In this embodiment, in order to further identify an accurate rope skipping action, the method for identifying the number of rope skipping times further includes: acquiring a maximum acceleration value and fourth time when the maximum acceleration occurs;

if the first time is within the time period between the take-off time and the third time, increasing the rope skipping times by 1, wherein the method specifically comprises the following steps:

if the maximum acceleration value exceeds the acceleration threshold value and the fourth time is within the time period between the take-off time and the third time, the rope skipping frequency is increased by 1.

Specifically, in the implementation process, the general frequency of the rope skipping is selected to be about 2HZ, the angle speed is obtained as the general frequency, and the acceleration threshold value is calculated. When the rope is jumped, when the acceleration sensing equipment in the small ball is configured to detect that the value of the acceleration at a certain moment is larger than the acceleration threshold value, the lowest point message is sent to the cushion, and the acceleration information at the moment is attached to the message, however, in the whole falling process of the small ball, the acceleration value for a period of time is larger than the acceleration threshold value, the lowest point moment is also in the time range, and the acceleration at the lowest point moment is the maximum value. When the rope skipping pad detects the time of the take-off, the time point of the time is recorded as T1, the time point of the time is recorded as T2, the process of one jump-off falling is recorded as the take-off times 1, the lowest value information sent by the received counterweight pellets is judged between the time T1 and the time T2, if the maximum acceleration value appears in the time period from the time T1 to the time T2, the success is judged, and if the maximum acceleration value does not appear in the time period, the failure is judged.

In order to take care of the use experience of the customer, the rope skipping confidence is established, and in the implementation process, the rope skipping success rate can be improved by setting an adjusting judgment method. The method does not judge the maximum acceleration between the time T1 and the time T2, and only if the maximum acceleration exceeds the acceleration threshold value, data are sent to the rope skipping pad, and the motion result is approximately judged.

Furthermore, the embodiment includes light interaction and/or sound interaction, specifically controlling the flicker frequency and/or sound level of the light based on the jump frequency, so as to increase the rope skipping fun through the light interaction and/or sound interaction, and the user can adjust the rope skipping rhythm according to the speed and/or sound level of the light.

Specifically, the interaction experience is adjusted according to the take-off frequency, and the interaction can be in a mode of light speed, sound height and the like. Frequency adjustment is achieved by setting a variable S, which has a maximum value, and the frequency of the adjustment of the interaction varies in proportion to or inversely with the size of S. Firstly, setting a fixed time t and an adjustment amount step, wherein a variable S in each period t is fixedly increased or decreased by step, when S becomes maximum or zero, the interaction frequency is minimum or maximum, when the rope is jumped, the variable S is reversely decreased or increased by each time the rope is jumped or fallen, and if the frequency period of the rope is smaller than the set time t, the variable S is gradually decreased or increased, so that the interaction frequency is changed in a direct or inverse proportion mode.
