The display screen a2 has a plurality of screens, and can divide the screen into a plurality of small squares to display the running states of athletes on different tracks, and can control starting to display the information of each athlete.

A plurality of wearable devices 5 for wearing or wearing on the body of the athlete. Have display screen B, power module B, bluetooth wireless transmission module B, rhythm of the heart monitoring module, transmitter A, receiver A, timing module, sensor A and vibration module among the wearable equipment 5. The wearable device 5 can communicate with the timing control module 1, transmit the athlete's information to the timing control module 1, and the coach can analyze the athlete's information. Wearable device 5 can also transmit information to the sportsman simultaneously, feeds back the sportsman with the vibration module. For example, after the athlete has run past the endpoint and time has been recorded, the vibration module can feed back a vibration signal to the athlete so that the athlete can know that the endpoint has passed, can stop, and know that information and time has been collected.

An origin commander 6 for commanding the athlete at the origin and triggering the timing module of the wearable device 5. The starting point starting device 6 comprises a starting module, a sound acquisition module, a Bluetooth wireless transmission module C, a transmitter B and a receiver B.
