Description

Compositive mahjong timer

The present invention relates to a kind of apparatus that utilizes microprocessor the athletic competition of 4 people's mahjong to be carried out timing.

Board games such as existing Chinese chess, go are two people match, so timer is provided with at two people's sequential operation, can not carry out 4 people's the timing that contains non-order status.

The object of the present invention is to provide a kind of compositive mahjong timer, can finish the person of playing a card at the characteristics of 4 people's mahjong and in the process of playing a card, bumping board, thick stick board, carry out timing control and demonstration.

The object of the present invention is achieved like this:

Compositive mahjong timer, its composition comprises: shell, be installed in the circuit board in the described shell, one-chip computer, the driving circuit that links to each other with the I/O mouth of this computing machine, the keyswitch circuit that links to each other with described computing machine and display circuit and display are housed, by the timing of computer realization order, bump the sequencer program control of the non-order timing of board state on the described circuit board.

Above-mentioned compositive mahjong timer, the timing of described realization order, the sequencer program that bumps the non-order timing of board state comprise:

A. the energized program begins;

B. just making makes it to make zero, and waits for button operation, and current window is set;

C. according to current window, send operation to allow sign;

D. the processing of order timing, the interruption timing processing of bumping the non-order timing processing of board state, fork board or thick stick board,

E. be provided with or revise display unit;

F. judge whether overtimely,, directly show if not overtime;

If g. overtime, then carry out overtime warning and demonstration.

The invention has the advantages that:

1. can carry out timing to the mahjong contest that 4 people carry out, by the program setting, not only can carry out the common timing of bridge etc., i.e. four order timing that the people plays a card by turns in order can also be carried out the timing of bumping operations such as board, thick stick board of sequential operation timing and non-order according to the distinctive rules of contest of mahjong.Can adapt to the requirement of the various special timing of 4 people's mahjong.

2. single-chip microcomputer is applied in the sports timing of mahjong, can utilize the basic function of computing machine not increasing under the preceding topic of hardware by popular software or programming, finish warning, shovel stops and return functions such as last time status, system reset, can be more complete carry out the management of computing machine to timing.

3. this product has the distinctive board function of bumping, promptly after the seller timing finishes, starting the player whose turn comes next picks up counting, in official hour, allow to bump the board operation, two families that can bump board, the operation push-button of in time pressing is effective, just begin to bump the board timing, bump the play a card timing of family of former regulation that the board timing recovers to have begun, and beginning deducts this timing bumping in the board timing, pick up counting then.Utilize the program step of this product, can accurately finish clocking capability.

4. be provided with interrupt function, promptly starting the clock or during the games, can cancel the timing of any family, promptly connect with the I/O mouth of computing machine (for example 89C51), reach the effect of bypass, realize interrupt function by operation ON/OFF key.

Adopt circuit of the present invention and program, can carry out the timing operation like this:

1. reset

When every dish begins, use specific purpose tool to press " reset key " by the professional, timer can show the time " 2:00 " of inserting, promptly 2 minutes automatically.

2. startup timing

When every dish begins, click Ben Men " timing key " by first participants in a bridge game that plays a card and start timer, and after playing a card, click " timing key " again and stop this timing and start the player whose turn comes next.

Behind the timer initiation, in official hour (5 seconds), the demonstration of clock can be glimmered.Allow nonsequential operation (bumping or the non-seller board of thick stick) this moment.Need to click this " timing key " when newspaper " bumping " or " thick stick ", the timer that the front can have been started restores, and its used time deducted from this timer and continues timing.

Each timer is pressed " timing key " as effectively, can send about 1 second left and right sides prompt tone, stops this timing and starts the player whose turn comes next.

3. system halt

Press " Pause key " timer and suspend, press the button once to suspend again and remove, timer continues timing.This key is generally used by the professional when on-the-spot dispute occurring.

4. timing is returned

Under halted state, press " backspace key ", can make the state before the present timing clock recovery starts to this, and after suspending releasing, from then on state begins to continue timing.

5. select and striking out

Penalized these personnel and to stop or use by the professional when lacking these personnel, in order to skip this timer." options button " of timer pushes " ON " retaining, shows selected participation timing; " options button " of timer pushes " OFF " retaining, then is out or absent.

6. system alarm

This timer when preset time is reduced to certain value, can provide prompting or warning for subtracting a timer.

If certain timer clock is less than or equal to 30 seconds excess time, this timer is started at every turn all can send a prompting long.

Timer is kept at 0 o'clock and sends interrupted alarm sound, and the timer locking.Need " options button " of this timer to be pushed " OFF " retaining, alarm release by the professional.Need click Ben Men " timing key " this moment, starts the timing of the next position timer.Three. the application notice of timer

1. the timer working voltage is: DC 5V.

2. Pause key ", " backspace key ", " reset key " only be placed in the timer of " east " locating and have, and could be operated with specific purpose tool by the professional.
