Abstract

The invention discloses a human body movement velocimeter based on radar. The human body movement velocimeter comprises a supporting table, a mounting plate, a radar velocity measurement sensor, a fixed tripod and a sound wave reflection vest. The velocimeter has the beneficial effects that radar speed measurement, electronic timing and electronic calculation of measurement results are facilitated by the aid of the radar velocity measurement sensor, reliability is high, the radar velocity measurement sensor can be conveniently fixed by the aid of the fixed tripod and is prevented from toppling during testing, a cursor is attached to the surface of the acoustic wave reflection vest and it is convenient to enhance the reflection precision of radar microwaves, so quite precise speed data is acquired. The radar velocity measurement sensor module adopts a GHZ microwave radar sensor with VCO modulation as a radar device for speed measurement, remote speed measurement can be conveniently achieved, the human body movement velocimeter is connected with a mobile terminal through a wireless communication module, a user can conveniently issue a speed measurement starting instruction through the mobile terminal, and the operation is more convenient.

Description

technical field [0001] The invention relates to a speedometer, in particular to a radar-based human body movement speedometer, which belongs to the technical field of speedometers. Background technique [0002] At present, there are generally four methods for measuring the moving speed of a human body. The first is to specify the length of the test route, manually time and record the movement time, and finally calculate the average displacement of the human body. This test method is more convenient, but only reference data can be obtained. This method cannot obtain real-time speed, nor can it when the human body is exercising. It is guaranteed to be completely straight, so the measurement accuracy of this test method is extremely low; the second method is to carry electronic tags on the tester, place readers at fixed intervals, and finally obtain segmental speed information, but this method also changes the human body movement. As a straight line, there are still errors; th...
