Description

The telechirics that is used for electronic timer with self-learning function

Technical field

The utility model relates to the telechirics with self-learning function that is used for 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.The problem that prior art exists:

1, when adopting general IR remote controller, if telepilot of the fixing coupling of each electronic timer is used other telepilot instead and just can not be operated after telepilot is lost or damaged.

If between 2 telepilots and the electronic timer be not fixing coupling, in the occasion of using a plurality of electronic timers, the situation of phase mutual interference between the telepilot can appear, and possibly occur operating a telepilot and the situation of a plurality of electronic timers responses arranged.

The utility model content

Above-mentioned defective to the prior art existence; The problem that the utility model will solve provides a kind of telechirics with self-learning function that is used for electronic timer; An electronic timer can be mated with different telepilots, and avoid the phase mutual interference between the telepilot.

For addressing the above problem; The utility model provides a kind of telechirics with self-learning function that is used for electronic timer, comprises that the interior burning that is arranged in the telepilot has the rf transmitter unit that has said telepilot address code in the radiofrequency signal of telepilot chip and emission of this telepilot address code; And be arranged in the said electronic timer and said rf transmitter unit between handle and extract the single-chip microcomputer of said telepilot address code and be used to preserve the storer of said telepilot address code through the rf receiver unit of radio communication, the radiofrequency signal that is used for that said rf receiver unit is received.

As preferably, be with 20 bit address sign indicating numbers in the said telepilot chip.

As preferably, said storer is EEROM.

The telepilot chip of the telechirics of the electronic timer of the utility model through being built-in with the telepilot address code be used to preserve the storer of said telepilot address code; Realized learning between electronic timer and the different telepilot coupling; And avoid the phase mutual interference of telepilot, prevent maloperation.

Fig. 2 is the synoptic diagram of the employed telepilot of telechirics with self-learning function that is used for electronic timer of the utility model.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail, but not as the qualification to the utility model.

As shown in Figure 1; The telechirics with self-learning function that is used for electronic timer of the embodiment of the utility model comprises being arranged in the telepilot 1 interior CMOS of the employing technology and burns the rf transmitter unit 11 that has said telepilot address code in telepilot chip 12 that this telepilot address code is arranged and the radiofrequency signal of launching; And be arranged in the electronic timer 2 and the rf receiver unit 21 through radio communication between the said rf transmitter unit 11, be used for the radiofrequency signal that said rf receiver unit 21 is received is handled and extracted the single-chip microcomputer 23 of said telepilot address code and is used to preserve the storer 24 of said telepilot address code.The telechirics of present embodiment adopts the less radio-frequency of 315MHZ to communicate; The radiofrequency signal that rf receiver unit 21 in the 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, according to resulting instruction score, the clocking capability of electronic timer 2 are controlled by single-chip microcomputer 23.Mate through the telepilot address code between electronic timer 2 and the telepilot 1.

The employed telepilot of the telechirics with self-learning function that is used for 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 all can be received its radiofrequency signal apart from the electronic timer in telepilot 1 certain limit.

Below in conjunction with Fig. 1 and Fig. 2 the process that the telechirics of present embodiment is carried out self study is described briefly.So-called " self study " refers between any a pair of telepilot and the electronic timer and can mate through the mode of storage telepilot address code in electronic timer.

The built-in telepilot chip 12 of each telepilot 1 all has a telepilot address code, and it is long by the learning key (not shown) on (3 second) electronic timer to finish the back in this electronic timer POST, and the I/O mouth of single-chip microcomputer 23 is changed to low level; Single-chip microcomputer 23 gets into the state of learning remote control device address code, at this moment, clicks any button on the telepilot 1; Rf transmitter unit 11 just sends the radiofrequency signal that has the telepilot address code; After rf receiver unit 21 receives said radiofrequency signal, give single-chip microcomputer 23, single-chip microcomputer 23 therefrom proposes the telepilot address; Store in the storer 24, as the foundation of identification telepilot.In use; Single-chip microcomputer 23 is when receiving the radiofrequency signal that contains remote information; Whether the telepilot address code of at first resolving, contrasting in this remote information is corresponding with the address code of self preserving; Fully corresponding just the execution accordingly of address code operated, if not correspondingly just this signal is ignored.

After damaging or change at telepilot, still can operate electronic timer, in the present embodiment, as preferred version, storer 24 adopts EEROM (electrically-erasable ROM (read-only memory)).New telepilot and electronic timer once mate again, and the telepilot address code of preserving in the storer 24 is just refreshed automatically and can use.In addition,, at will select a telepilot and the electronic timer of wanting to mate to carry out telepilot address code coupling No. one time, but just operate as normal needn't worry that telepilot mixes up in the occasion that a plurality of identical telepilots are arranged.

In the present embodiment, the model of telepilot chip is EV1527, is to adopt CMOS (CMOS) but the IC of the pre-burning ISN that technological design is made; The ISN of this IC has 20 bits; But code combination in pre-burning 1048576 (i.e. 2 the 20 powers) group can form 1048576 different telepilot address codes, reduces the probability of repeated code between the telepilot; Guarantee same on-the-spot many cover electronic timers and the telepilot of using, can the phase mutual interference.

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.
