Specific embodiment
Realization of the invention is specifically described below.
Such as Fig. 1, the present invention includes master control pusher side and from pusher side, master control pusher side include host SCM and with host list
The DS1302 clock module of piece machine connection, AT24C02 module, 8 common anode numeral method drive modules, Keysheet modules, host
RS-485 module and power supply include that slave single-chip microcontroller and the slave large-size screen monitors charactron connecting with slave single-chip microcontroller are aobvious from pusher side
Show drive module, slave acoustic-optic alarm, slave RS-485 module and power supply, host RS-485 module and slave RS-485 mould
Block is connected using RS-485 mode, and host SCM passes through host RS-485 module to slave single-chip microcontroller sending time signal harmony
Visual alarm.
It is preferred that host SCM and slave single-chip microcontroller are single-chip minimum system, it is more advantageous to equipment
It minimizes and portable.
Host SCM is core, and other circuits of master control pusher side are connect with host SCM, and Fig. 3 is 8 common anode numbers
Code pipe driver module circuit diagram, Fig. 4 are DS1302 clock module circuit diagram, and Fig. 5 is host RS-485 module
Circuit diagram, Fig. 6 are AT24C02 modular circuit schematic diagram.It is preferred that Keysheet module is matrix keyboard circuit, circuit such as Fig. 7
It is shown.
Host SCM and slave single-chip microcontroller are single-chip minimum system, have selected low-power consumption, 8 of high-performance CMOS
AT89S52 monolithic embedded microcontroller cpu chip uses as shown in Fig. 2, having 8K in-system programmable components flash storage
The manufacture of Atmel company high-density nonvolatile memory technology, chip completely compatible with the instruction of industrial 80C51 product and pin
Included programming interface.AT89S52 has following standard feature: 8k bytes Flash, 256 byte RAM, 32 I/O mouth lines are guarded the gate
Dog timer, 2 data pointers, three 16 bit timing devices/counters, 2 grades of interrupt structures of 6 vector, full duplex serial port,
Crystal oscillator and clock circuit etc. in piece.It is preferred that the port the AT89S52 planning of host SCM is as follows in the present invention:
P1.0: the clock input of AT24C02 is connect；
P1.1: the data terminal of AT24C02 is connect；
P1.6: Keysheet module line interface and downloading programming interface share；
P1.7: Keysheet module line interface and downloading programming interface share；
P0 mouthfuls: 8 common anode numeral method segment encode data ports；
Select mouth in P2 mouthfuls: 8 common anode numeral method charactron positions.
Wherein the port P1.6 and P1.7 is the programming interface of chip initial designs, also referred to as downloading programming interface, i.e. the external world is set
Thus the program of meter interface can be loaded into single-chip microcontroller and implement, due to Keysheet module in practical operation and downloading programming interface two
Person can't use simultaneously, therefore timesharing use will not cause to conflict.
In master control 8 common anode numeral method drive module circuit diagrams of pusher side as shown in Figure 3, P0 mouthfuls of selection total as 8
Positive numeral method segment encode data port selects P2 mouthfuls as 8 common anode numeral method charactron positions and selects mouth.It is filled in single-chip microcontroller
Common timing program is carried, in conjunction with DS1302 clock module, common anode numeral method Beijing time, 0 can be passed through in master control pusher side
~99 points and 0~59 second may be selected adjustment divide timing to countdown, the second timing that 0~99 second arbitrarily adjusts is countdowned,
Key module can be used for the pause or adjustment of time, the setting of time numerical value, reset etc., belong to the ordinary skill in the art, no longer
It is described in detail.Specific implementation citing: when showing what day and Hour Minute Second, 8 designs of Digital sum pipe Far Left one show week
Several, when six displays in right side, minute, second, left 2 blank can be used for dividing week and Hour Minute Second；In display match duration total score
In the case of second countdown or countdown in 24 seconds, the total every minute and second countdown of four LED display match durations of Far Left, rightmost two
LED shows countdown in 24 seconds, and the display tube among the two is without display, for being spaced.
Master control pusher side is generally hand-holdable, for judge use, from pusher side by large-size screen monitors charactron progress competition field synchronize it is aobvious
The temporal information for showing master control pusher side is believed from pusher side host RS-485 module to the display time for sending large-size screen monitors charactron from pusher side
Number, match the competition fields such as the countdown of total duration every minute and second and 24S countdown signal, sound and light alarm signal display signal.
From pusher side also using slave single-chip microcontroller as core, the circuit diagram of slave single-chip microcontroller is as shown in Figure 8.From its of pusher side

It is preferred that three groups of charactrons are at the arrangement of falling triangle disposition, as shown in Figure 9.For example, when showing the time, upper left side two to
When display, upper right side two is to show point, and middle downside two is to show the second；Display match the countdown of total duration every minute and second and
In the case of countdown in 24 seconds, the minute of upper left side two to show match total duration every minute and second countdown, upper right side two to
The second of display match total duration every minute and second countdown, and second of the middle downside two to show 24S countdown.Large-size screen monitors charactron can be adopted
Display mode is driven with dynamic scan.The circuit of slave acoustic-optic alarm is driven by the port P1.0 of slave single-chip microcontroller, is used for
Time reminding.Such as sound-light alarm is issued when the compete countdown of total duration every minute and second or 24S countdown are to 0, due to principal and subordinate's monolithic
Machine communication, the corresponding competition field temporal information of simultaneous display can be resetted in master control pusher side by key module, be released corresponding
Sound-light alarm.
