And the technical scheme has high cost.

Disclosure of Invention

The invention aims to overcome the problems of poor accuracy and timeliness and high cost in the prior art, and provides a detection method and a detection device for a flat plate support.

In order to solve the technical problems, the invention adopts the technical scheme that:

a detection method for a flat plate support is provided, which comprises the following steps:

the method comprises the following steps: the human body is kept prone, infrared sensor components are arranged at the ankle part and the shoulder part, and a photosensitive sensor is arranged at the crotch part; the infrared sensor assembly and the photosensitive sensor are electrically connected with a timer; the infrared sensor assembly and the photosensitive sensor are both arranged on the center line of the human body.

Step three: starting a timer, and starting to time the duration time of the flat plate support; if the infrared components are not paired or the infrared light does not pass through the light sensitive sensors, the timer pauses until the infrared components can be paired and the infrared light can pass through the light sensitive sensors in the crotch.

In the above technical solution, the standard motion of the flat plate support is that the trunk is straight, the shoulder, the hip and the ankle are kept in the same plane, that is, three points of the shoulder, the crotch and the ankle are on the same inclined straight line, after the infrared sensor assembly is installed on the shoulder and the ankle, the photosensor in the crotch is located between the emitting end and the receiving end of the infrared sensor assembly, the emitting end can emit infrared rays, and the infrared rays pass through the photosensor in the crotch to reach the receiving end at the other end, which indicates that the shoulder, the crotch and the ankle are kept in the same plane, and meets the motion standard of the flat plate support, so that a timer electrically connected with the infrared sensor assembly and the photosensor can perform timing. When the flat plate support deforms along with time, such as the hip position of a body protrudes upwards or sinks downwards, the shoulder sinks, and the like, infrared rays at the transmitting end cannot pass through the photosensitive sensor or cannot be received by the receiving end, and at the moment, the timer stops timing until the action is adjusted to be standard action again. Because the timer only needs to start or stop timing according to the electric signals of the infrared sensor assembly and the photosensitive sensor, when the action is not standard, the timer can quickly respond and stop timing. Meanwhile, when the emission angle of the emission end is corrected, under the standard action, the judgment of the standard action can be quickly and accurately judged by a judge according to the personal condition, and the labor cost can be saved when the judgment of the judge is not needed after the initial adjustment of the infrared sensor assembly is completed.
