Description

The basketball electronic timer

Technical field

Timing in 24 seconds and single-unit time set that the utility model uses when relating to a kind of Basketball Match specifically are a kind of basketball electronic timers.

Background technology

At present, basketball electronic timer (hereinafter to be referred as timer) on the market generally comprises controller and timing display device, controller is installed on the technology platform, for technician's operation, the timing display device then is installed on the basketball stands of both sides, place, watch for spectators and sportsman, both communicate by cable.Also there are following two weak points in the timer of said structure in the use of reality:

1, the controller of prior art timer and timing display device are owing to be to be connected and to communicate by cable, and also need when installing cable is connected up with the functional reliability of assurance timer, so the timer of prior art installs inconvenience.

2, because the distance of controller and timing display device is distant, thereby it is also just long to connect their telecommunication cable, and cable is long more with regard to the easy more external interference that is subjected to, thereby the timer communication of prior art is interfered easily, functional reliability is low.

The utility model content

The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of easy for installation and be not vulnerable to external interference, basketball electronic timer that functional reliability is high.

The technical solution of the utility model is, a kind of basketball electronic timer is provided, comprise controller and timing display device, be equipped with wireless communication module in described controller and the timing display device, the wireless communication module in the described controller is connected with radio communication mold block signal in the timing display device.

After adopting above structure, the utility model compared with prior art has the following advantages:

1, the utility model basketball electronic timer is owing to adopted the sending module and the receiver module that can carry out radio communication, need not to connect up and to realize communication between controller and the timing display device, solved the problem of the installation inconvenience that timer in the past brings owing to wiring, thereby the utility model installs more convenient.

2, owing to be radio communication between controller of the present utility model and the display device, it is long and be subject to the problem of external interference so the functional reliability height of the utility model timer therefore to have solved timer cable in the past.
