The setting of voice control chip, phonetic storage chip, audio amplification chip and loudspeaker realizes the voice of timer It reports, avoids contestant or trainer and need that timer is taken to understand fixture or instruction after match or training It is the problem of practicing the time, convenient and efficient.

Embodiment eight

On the basis of embodiment seven, micro-control unit includes growth data interface.

Micro-control unit can be with external various equipment, for example, can be to external synchronism output meter by growth data interface When data, for extend display or connection accumulation hub carry out achievement acquisition, extend the function of timer.

Embodiment nine

On the basis of any embodiment in embodiment three to embodiment eight, as shown in figure 5, timer further includes difference Power switch 7, storage button 8 and the reset key 9 being connect with control circuit 2, second source switch, storage button and reset are pressed Key is embedded in the surface of shell respectively.

After timing, the display screen of timing viewing area can show always the time of last time timing, at this time timer User can select to store the time or reset timer to prepare next round timing again.It is stored if user touches Button, then the symbol flicker of the Historical Results memory block in control circuit control display, control circuit will preferentially select one The region for not storing the time carries out the storage of time, if user wants to change storage region, can touch the first touch sensible Device or the second touch inductor select other storage regions.After choosing storage region, user's long-press storage button two seconds, Then games results can be stored to the region by control circuit.If user wants reset timer to prepare next round timing again, User touches reset key, and control will be 0 resetting time:00.000, and wait for the beginning of next round timing.It is convenient fast Victory enhances user experience.

For example, as shown in fig. 6, this timer (is mainly by main circuit board (being control circuit 2), left hand induction zone First touch inductor 31), right hand induction zone (be the second touch inductor 32), loudspeaker 44 and shell (being shell 1) group At.Wherein, large screen display (be display 6), voice module (including voice control chip 41, phonetic storage chip 42, Audio amplification chip 43), touch power switch 7, touch storage button 8, touch reset key 9, red indicating light (be first Color indicator light 51), green indicator light (be the second color indicator light 52), data-interface (being growth data interface) equal position It is shown for timing viewing area 61, Historical Results memory block 62, average time on main circuit board 2, being divided on large screen display 6 Area 63.

Large screen display can be liquid crystal display or light-emitting diode display.Power switch, storage button, reset key It is touch key-press, left hand induction zone and right hand induction zone are made of highly sensitive touch sensor, can be incuded in real time in one's hands Whether induction zone is placed on.

Entire timer is controlled by MCU, and left hand induction zone, voice module, touches power switch, touches right hand induction zone Storage button, touch reset key, red indicating light, green indicator light, data-interface are both connected on main control module, master control mould Block connects driver module, and large screen display connects driver module.

Voice module can send out corresponding prompt tone according to the state of current timer, and can terminate again timing it Voice broadcast timing time afterwards.

Data-interface can carry out achievement to external synchronism output chronometric data for extending display or connection accumulation hub Acquisition.Data-interface and serial ports that the connection between display can be wired, SPI, IIC communication are extended out, can also be wireless RF is communicated.Extend out display can simultaneous display timer timing content, other entrants for showing match or sanction Sentence, spectators etc..

Before timing starts, timer power supply is opened, the timing viewing area resetting time of timer is 0:00.000.Ginseng Left and right both hands must be placed on induction zone by match person, ensure that both hands must not carry out any operation before match in this way.When both hands are complete When portion is placed on induction zone, red light lights immediately, and loudspeaker can be simultaneously emitted by corresponding prompt tone and indicate that both hands correctly playback.

After both hands are placed into induction zone, it is necessary to place two seconds or more, green light lights at this time, and loudspeaker can be simultaneously emitted by accordingly Prompt tone indicates the timing that can take the field at any time.If there is any one hand to leave induction zone in two seconds, both hands are needed Playback, and place two seconds again or more, can just take the field timing.

After green light lights, entrant can proceed by match at any time, and timer can leave induction zone in any one hand It obtains and starts timing at that moment, loudspeaker can also send out corresponding prompt tone and indicate that timing starts simultaneously, and accuracy of timekeeping is 0.001 second.

In timing course, the timer moment detects the induction zone of right-hand man, when detecting that two hands return to induction zone Stopping timing at that moment, then this time as really start the time of racing match operation, loudspeaker while end Corresponding prompt tone can be sent out, and timing time that voice broadcast is current " when xx xx divide xx seconds xxx milliseconds ".

The sound prompt function opened or closed in timing course can be set, and timer can be according to the interval time of setting It sends out prompt tone, reminds entrant's time schedule, corresponding prompt tone can also be sent out when more than the games results of storage.

Timer is powered by dry cell or button cell, is not necessarily to power supply adaptor, is convenient for carrying and uses.

Timer uses touch power switch, and power supply can be opened by touching, and power supply can be closed again by touching.

Timer, 30 minutes will automatic shutdown without any operation under non-time status.

After timing, timing viewing area can show always the time of last time timing, can store the time at this time, or Person's reset timer prepares next round timing again.If touching storage button, the symbol of Historical Results memory block will It flickers (5 Historical Results can be stored altogether), preferential selection one was not stored the region of time by timer, was deposited if wanting to change Storage area domain can touch left hand induction zone or right hand induction zone to select other storage regions.It is long after choosing storage region By storage button two seconds, then games results are stored to the region.To reset timer, prepare next round timing again, then Reset key is touched, timer will be 0 resetting time:00.000 and wait for the beginning of next round timing.

If following and storage fixture can be two seconds with long-press reset key just by timer reset, adjust again Go out last time games results, is then stored again according to storage operating procedure.

After having updated Historical Results every time, average time viewing area can all recalculate Historical Results and show.

Battery is taken out in shutdown, does not all interfere with the Historical Results of storage.Storage button and reset are pressed except non-concurrent Button removes currently stored Historical Results, or presses storage button and reset key simultaneously and keep removing institute in three seconds There are Historical Results.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
