Description

Human body ultrasonic detection system

Technical Field

The invention relates to the field of massage and health care, in particular to a human body ultrasonic detection system.

Background

In the existing massage chair and the like, the body shape of a massage component is detected by shoulder position detection or multipoint sampling current detection. The shoulder position detection can only roughly detect the shoulder position and estimate the massage position, and the whole body accurate massage can not be carried out and the shoulder position can not be used as the reference of the 3D extension massage. The multipoint sampling current detection is that the current detection is carried out by carrying out multipoint extension by using a 3D extension motor in sampling, and the position of a human body curve is judged according to the current magnitude. The mode can detect the shoulder position and also can detect the approximate solid curve of the human body, and can better massage the human body including the 3D extending part. But the defect is that the requirement on the continuity of the motor transmission mechanism is higher, otherwise, the human body curve cannot be accurately detected. Secondly, the number of sampling points of the detection mode is limited, otherwise, the experience feeling is seriously influenced (the process is to upwards detect the current by using massage heads at different parts of a human body). Therefore, the accuracy is not too high as a whole, and the experience feeling is poor.

Detailed Description

As shown in fig. 1 to 3, a human body ultrasonic detection system comprises a massage manipulator arranged in a massage device, wherein the massage manipulator runs in the massage device to form a massage manipulator up-and-down running track 3, an ultrasonic receiving-transmitting probe 1 is arranged on the massage manipulator, the ultrasonic receiving-transmitting probe 1 is in signal connection with a PWM controller, the ultrasonic receiving-transmitting probe 1 faces a human body supporting surface 2 of the massage device, and the detection frequency of the ultrasonic receiving-transmitting probe 1 is 25-1000 KHz.

Furthermore, the PWM controller is in signal connection with the massage manipulator, and the ultrasonic transceiving probe 1 comprises an ultrasonic transmitting probe and an ultrasonic receiving probe; alternatively, the ultrasonic transmission/reception probe 1 is a probe that transmits and receives ultrasonic waves. The probe chip integrating ultrasonic wave transceiving is a TCT40 ultrasonic wave transceiving chip, wherein the chip of the PWM controller is an L298 control chip.

The distance between the massage manipulator and the human body supporting surface 2 is set to be X, and when the massage manipulator moves in the up-and-down moving track 3 of the massage manipulator, the ultrasonic receiving and transmitting probe 1 measures the distance D between the human body supporting surface 2 and the massage manipulator in the up-and-down moving track 3 of the massage manipulator. Thus, the data D is the data of the X-point robot extending to the human body. The upper and lower operation X1............... n will have the corresponding extension data of the massage manipulator of D1........ Dn, so that the massage manipulator can precisely massage the whole human body in the whole massage process. The massage can not be performed in some places and the massage in some places is too heavy;

when the ultrasonic wave receiving head works, the ultrasonic wave transmitting head transmits 4-8 continuous ultrasonic wave pulses, and the distance from the transmitting end to 2) = (time x sound velocity (340M/S))/2 can be calculated by the program according to the return time of the ultrasonic wave receiving head.

With PWM triggered ranging we can use pulse levels of 1us to 40us period (25K-1 MHz) since the test range is typically between 10cm to 50 cm. The simpler the hardware is to use the lower the acoustic frequency, the lower the relative cost implementation cost, but the lower the accuracy, when using 40KHz ultrasound detection, the minimum accuracy in terms of 4 pulse settling response times is: (4x (25/1000000) x340)/2= 17mm, and a theoretical accuracy of 1.7mmm (among other environmental factors) can be achieved if 400KHz is used. But in the practical application process, the ultrasonic wave of 100-200KHz is only required to be accurate to about 5mm, so that the invention can be realized.

The massage manipulator of this system moves about forming massage manipulator in massage equipment and moves the orbit, install ultrasonic transceiver probe on massage manipulator, ultrasonic transceiver probe signal connection PWM controller, ultrasonic transceiver probe is towards massage equipment's human holding surface, the ultrasonic transceiver process that adopts ultrasonic transceiver probe directly measures the position and the distance of human each position curve relative massage manipulator, whole massage in-process massage manipulator can all be accurate massage whole people like this, be unlikely to some local massages can not arrive, there is the overweight of some local massages, it is fast to have detection speed, the characteristics that the sampling point is many, whole testing process need not stretch out the massage head specially and surveys, it is fast to survey, do not influence customer experience, and it is accurate (can be accurate within 5mm to detect the location).
