Abstract

The utility model discloses a remote control system of an electronic scoreboard. The remote control system comprises a radiofrequency transmitting unit and a radiofrequency receiving unit, wherein the radiofrequency transmitting unit is arranged in a remote controller, and the radiofrequency receiving unit is disposed inside the electronic scoreboard and is communicated with the radiofrequency transmitting unit by radiofrequency. The remote control system of the electronic scoreboard has the advantages that the remote control system is not limited by directions when used owing to a radiofrequency communication mode, and operation is greatly facilitated.

Description

A kind of telechirics of electronic timer

Technical field

The utility model relates to a kind of telechirics of electronic timer, is applied to various with the match place than resolution victory or defeat.

Background technology

Billiard ball, table tennis etc. are ball all to be with than differentiating victory or defeat, for the ease of understanding the match process, needs to use scoreboard to show score in real time.Scoreboard the earliest adopts manual mode bonus point or subtracts branch, for the ease of operation, uses a teleswitch scoreboard is operated.When a certain side needed bonus point, the judge was with regard to the bonus point button on the remote controller, and scoreboard is just operated according to the instruction of being received.In the prior art; Common employing infrared ray between telepilot and the scoreboard transmits; Need directed remote control, promptly telepilot need be aimed at the infrared interface on the scoreboard when operation, otherwise scoreboard just can not receive the instruction of telepilot; The promptness that this has influenced operation greatly can not in time show on scoreboard when the player obtains bonus point.

The utility model content

To the above-mentioned defective that prior art exists, the problem that the utility model will solve provides a kind of telechirics of electronic timer, can carry out straighforward operation to electronic timer quickly and easily.

For addressing the above problem; The utility model provides a kind of telechirics of electronic timer, comprises being arranged at the rf transmitter unit in the telepilot and being arranged in the said electronic timer and the rf receiver unit through radio communication between the said rf transmitter unit.

The telechirics of the electronic timer of the utility model need not considered direction through adopting the mode of radio communication during use, greatly facilitates operation.

Description of drawings

Fig. 1 is the structured flowchart of telechirics of the electronic timer of the utility model;

Fig. 2 is the synoptic diagram of the employed telepilot of telechirics of the electronic timer of the utility model.

Embodiment

Specify the embodiment of the embodiment of the utility model below in conjunction with accompanying drawing.

As shown in Figure 1; The telechirics of the electronic timer of the embodiment of the utility model comprises being arranged at the rf transmitter unit 11 in the telepilot 1 and being arranged in the electronic timer 2 and the rf receiver unit 21 through radio communication between the said rf transmitter unit 11.This telechirics adopts the less radio-frequency of 315MHZ to communicate,

The radiofrequency signal that rf receiver unit 21 in the said electronic timer 2 is received is exported to the external interrupt I/O mouth of single-chip microcomputer 23; Single-chip microcomputer 23 is through address contrast, data decode; Distinguish whether this less radio-frequency information that receives is the operation to this scoreboard; Decipher out relevant right instructions through communication protocol again;,, deliver to the back level again and drive, show through corresponding demonstration or operate the I/O mouth according to referring to that resulting instruction controls score, the clocking capability of electronic timer 2 by single-chip microcomputer 23.

The employed telepilot of the telechirics of the electronic timer of the utility model as shown in Figure 2; In the time of need carrying out associative operation; Only need press corresponding button, the rf transmitter unit 11 in the telepilot 1 just to around send corresponding radiofrequency signal transmit because radiofrequency signal has non-directional; And the advantage of long transmission distance, the electronic timer that is located in the certain limit all can be received its radiofrequency signal.

The telechirics of the electronic timer of the utility model adopts radio frequency to communicate;, remote control need not consider direction when using; Needn't hold telepilot and aim at electronic timer; Play due remote control effect accurately even be placed on can make things convenient in the pocket, on the big event field, just can control the scoreboard that hang over diverse location and be provided with the identical address sign indicating number with same telepilot easily, very easy to use.

Certainly; The above is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.

Claims

1. the telechirics of an electronic timer is characterized in that, comprises being arranged at the rf transmitter unit in the telepilot and being arranged in the said electronic timer and the rf receiver unit through radio communication between the said rf transmitter unit.
