Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In a first aspect of the present invention, as shown in fig. 1, an anti-pinch control method S100 is provided, including:
s110, elastic wave signals generated by the target equipment in the motion process are collected, and the elastic wave signals are converted into electric signals.
Specifically, in this step, the target device may be an in-vehicle device, such as a trunk, a window, and the like, and the target device may also be a home device, such as a home appliance and the like. Besides, the target device can be defined as some other controllable devices according to actual needs. The sensor can be used for acquiring an elastic wave signal generated by the target equipment in the motion process and converting the elastic wave signal into an electric signal. The sensor may be an elastic wave sensor including, but not limited to, a piezoelectric sensor, a strain gauge sensor, etc., and the piezoelectric sensor may include a piezoelectric ceramic sensor, a piezoelectric thin film sensor, a piezoelectric crystal sensor, or other sensor having a piezoelectric effect.
And S120, determining whether the target equipment meets an obstacle in the moving process according to the electrical signal.
Specifically, in this step, for example, the electrical signal may be compared with a preset voltage threshold, and it is determined whether the target device encounters an obstacle during the movement according to the comparison result. Of course, besides, other determination means may also be used to determine whether the target device encounters an obstacle during the movement process, and those skilled in the art may determine the determination according to actual needs.
And S130, when an obstacle is encountered, controlling the target equipment to stop moving or retreat for a preset safe distance.
The anti-pinch control method comprises the steps of firstly collecting elastic wave signals generated by target equipment in the moving process and converting the elastic wave signals into electrical signals; secondly, determining whether the target equipment meets an obstacle in the movement process according to the electrical signal; and finally, when an obstacle is encountered, the control target device stops moving or retreats for a preset safe distance. The obstacle information in the movement process of the target equipment can be effectively identified, so that intelligent anti-pinch can be realized, misoperation of a user is avoided, and meanwhile, the condition that the target equipment is damaged and the like can be avoided.
In order to accurately realize intelligent anti-pinch, the step S120 specifically includes:
and respectively comparing the signal characteristic value of the electrical signal with a pre-stored operation event characteristic value and an opening and closing event characteristic value, and judging whether the electrical signal meets an obstacle.
Specifically, whether the difference between the signal characteristic value of the electrical signal and the pre-stored operating event characteristic value exceeds a first threshold value is judged, if yes, whether the difference between the signal characteristic value of the electrical signal and the pre-stored opening and closing event characteristic value exceeds a second threshold value is judged, and if yes, it is determined that an obstacle is encountered.
For example, in this step, the first threshold and the second threshold may be determined based on experimental or empirical values, the operation event characteristic value should be a characteristic value corresponding to an elastic wave signal generated when the target device does not encounter an obstacle during the movement, and the opening/closing event characteristic value should be a characteristic value corresponding to an elastic wave signal generated when the target device does not encounter an obstacle at both the opening moment and the closing moment. Assume that the first threshold value is b1, the second threshold value is b2, the operational event characteristic value is n1, the signal characteristic value is n, and the opening/closing event characteristic value is n 2. Let a1 be n/n1, assuming a1 < b1, it can be determined that no obstacle has been encountered; on the contrary, if a1 > b1 indicates that an obstacle may be encountered, and further confirmation is required, in this case, let a2 be n/n2, and if a2 < b2, it may be determined that no obstacle is encountered; on the contrary, if a2 > b2, it is determined that an obstacle exists, and the target device needs to stop moving or move back for a certain distance.
It should be noted that, in addition to comparing whether the ratio of the signal characteristic value to the operation event characteristic value exceeds the first threshold and the second threshold, whether the difference between the signal characteristic value and the operation event characteristic value exceeds the first threshold and the second threshold may also be compared, and the comparison may be specifically determined according to actual needs.
More specifically, in this step, the signal characteristic value of the electrical signal may be analyzed in a time domain and a frequency domain, where in the time domain, the signal characteristic value may be a voltage amplitude value or a voltage fluctuation value corresponding to any time, and in the frequency domain, the signal characteristic value may be an energy value corresponding to any frequency domain, and the like. After the signal feature values are obtained, the signal feature values may be combined into a signal feature vector, and the signal feature vector includes values (voltage amplitude, voltage fluctuation value, energy value, etc.) and directions of the values, for example, a voltage amplitude of +5V indicates that the voltage amplitude at the time is 5 and is positive, whereas a voltage amplitude of-5V indicates that the voltage amplitude at the time is 5 and is negative.
It should be noted that, the operation event characteristic value and the opening/closing event characteristic value may be stored in advance, and the user may also define the operation event characteristic value and the opening/closing event characteristic value by himself, for example, the user collects, according to the vehicle type of the user, an elastic wave signal that the target device does not encounter an obstacle during the movement process and an elastic wave signal that the target device does not encounter an obstacle at the opening/closing moment, converts both of the signals into corresponding electrical signals, and forms the characteristic values corresponding to the electrical signals into the operation event characteristic value and the opening/closing event characteristic value.
In order to accurately realize intelligent anti-pinch of the target device, the step S120 specifically includes:
and calculating a motion resistance force value of the target equipment according to the electrical signal.

In addition, an energy value can be calculated according to the electrical signal, and a motion resistance value can be calculated according to the energy value, specifically as follows:
in particular, in the present embodiment, one or more sensors C may be utilized1To CnRespectively converting the respective received elastic wave signals into electrical signals D with the frequencies consistent with those of the elastic wave signals received by the respective elastic wave signals1To DnThen according to each electrical signal D1To DnRespectively calculating the energy value E of each electrical signal1To EnAnd finally, the energy value E is used1To EnTo obtain a final value of the total energy of the elastic wave (when only one energy value E is obtained) 1When the sum is not accumulated and averaged or 1 × E11) is added; it should be noted that, in the above process, the method for calculating the energy value according to the electrical signal can be mainly calculated by the following formula:
In the above formula, m is the number of collected signal points; n is the number of signal points determined by selecting the wavelength of the electrical signal with the preset length according to the actual situation, and related technicians in the field can select the setting according to the actual needs, and the invention is not further limited herein; e is the energy value of the electrical signal.

and processing the electrical signals in the preset time period, and calculating the motion resistance value.
