Embodiment 1

[0049] The present invention includes a sports timing device, which is used as a recording device for athletes passing through checkpoints. The sports timing device communicates with the NFC tags carried by the athletes. The NFC tag that is carried, this type of NFC tag has a storage space of 800 bytes, and the price is low.

[0050]The main function of the resistor in this embodiment in the sports timing device is to limit the current and provide load, and does not participate in the construction of high-frequency circuits. Therefore, ordinary thick-film chip resistors or thick-film precision resistors can meet the requirements; in addition , since the sports timing device is a portable device, the layout area is very important in the circuit design, and the circuit board area needs to be compressed as much as possible, and the volume of the ceramic capacitor can be made very small, so this implementation The capacitor described in the example is a ceramic capacitor. At the s...

Abstract

The invention discloses a sports timing device and method, which uses Sub-G radio frequency communication to send the NFC tag data and timing information to a wireless access point. Compared with the prior art, the invention ensures long-distance transmission and transmission rate Simultaneously, the present invention adopts the control chip of integrated single-chip microcomputer and Sub-G radio frequency communication, reduces the layout area and the number of components of the sports timing device, ensures that the sports timing device is light and easy to carry, and is convenient for the staff before the game. Setup and post-race recovery.

Description

technical field [0001] The invention relates to the field of sports timing, in particular to a sports timing device and method. Background technique [0002] Orienteering is an outdoor sport. Participants need to hold a map and visit various checkpoints according to its instructions and punch in records. The sports timing device is the key device for recording the order of athletes' visits. Because some games need to be played in a large area in the wild, the wireless transmission distance is long, and the signal is weakened when the radio wave encounters obstacles, and the athlete's motion data cannot be transmitted to the server in time, which affects the judgment of the game result. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a sports timing device and method supporting long-distance real-time transmission. [0004] A sports timing device, comprising: a radio frequ...
