Detailed Description

In an embodiment of the invention, the race organized in the open area refers to a non-field race, or a race pattern juxtaposed to a field race, such as a swimming race organized in open waters, a motocross, a marathon, a non-field bicycle race such as the cycloqinghai lake, and the like. The common attribute of such games is that there are generally many contestants, each player cannot be taken care of by the organizer of the game, and in the process of the game, the movement tracks of the contestants are complicated and the distribution of the players is wide. For safety, for example, in swimming competitions organized in open water, once an athlete drowns, the athlete often cannot give an alarm to the outside in time, or even if the athlete has an alarm, the athlete cannot be accurately positioned.

It should be noted that the timing system is often a system rather than a single device for timing purposes, and the current timing system is often integrated with more functional units.

In the above, position data, gyroscope data and heart rate data are generated, collectively referred to as game data. While data stored by, for example, the host-side database for comparison with match data is collectively referred to as experience data.

The position data, the gyroscope data and the heart rate data are all transmitted to the base station through the UWB positioning module. The housing incorporates an integrated circuit and may be configured with, for example, a distress button on the housing. The integrated circuit can be also provided with a charging module; when the SOS button is pressed, the UWB positioning module sends a preset SOS instruction to the base station and presents the position and ID of the positioning module to the competition organizer through a screen on the host side, for example. The charging module provides a contact or wireless charging mode.
