[0038] The jump measurement device is used in the following manner: the height module senses the distance h1 between the height module and the test area, and transmits the distance h1 to the control module; when the tester stands in the test area, the height module senses the distance h2 from the height module to the top of the tester's head, and transmits the distance h2 to the control module, and the control module obtains the tester's height h3 by subtracting the distance h2 from the distance h1; when the tester stands on the test area, the electric pulse of the grating sensor is blocked, and when the tester starts to jump, the electric pulse of the grating sensor is connected and sends a trigger signal to the control module, so that the control module starts timing, and when the tester falls back into the test area, the electric pulse of the grating sensor is blocked again, and at this time the control module stops timing and obtains the tester's air time t.

[0039] To summarize, a trigger module is fixedly connected to the base frame, and the trigger module is used to sense and trigger the control module for timing.

[0043] A jump measurement method is introduced below, and the jump measurement device mentioned above can be used to implement the following method.

The control module determines that the tester jumps in the test area, and the control module starts timing after receiving the first connection signal. Using the trigger module to trigger the control module for timing is more accurate than manually pressing the stopwatch to time.

[0049] e. The height module senses the distance h between itself and the top of the tester's head multiple times and sends the distance h to the control module. At the same time, each time the height sensing module sends the distance h, the control module records the corresponding time T1;

[0050] f. The control module compares the received distances h in the order in which they are received, and obtains the minimum data h1. The time T1 corresponding to the minimum data h1 is recorded as the rise time T2;

[0051] g. The control module subtracts the minimum data h1 from the distance H2 to obtain the height h of the highest point jumped by the tester;

[0052] h. After the trigger module is blocked again, the trigger module sends a second blocking signal to the control module, and the control module determines that the tester has fallen back into the test area, then the control module stops timing and records the time at this time as the empty time t;

[0053] i. After the trigger module is turned on again, the trigger module sends a second turn-on signal to the control module, and the control module clears the recorded data.

[0054] As a preferred method of this embodiment, step j is also included after step h is executed: the control module sends the collected and calculated data to the mobile terminal.
