Description

Goal timing display

The utility model is a kind of timing display of croquet match usefulness.

When croquet is competed, according to regular needs full time was controlled in 30 minutes, each player in's of both sides hitting time will be limited in 10 seconds simultaneously, the complete backward timing and scoring means that adopt people's work card stopwatch, abacus bead to score respectively of croquet match at present, each 10 team member of both sides according to number order enter the court in turn, 10 seconds of timing are all wanted in each team member batting, and both timing uncertainty was true, and more loaded down with trivial details.

The croquet timing display that the utility model aims to provide a kind of energy self-clocking score and shows.

For reaching above-mentioned purpose, the utility model has adopted following structure: it comprises power supply, power switch S ₁, timing control enclosure box body 1, control knob S ₂, display 2, hummer, single-chip microcomputer etc., single-chip microcomputer external clock circuit, address latch, program storage, display decoder driver, this part circuit all are contained in the timing control enclosure box body 1, display decoder driver and display 2 link, and it is characterized in that: described control knob S ₂Be self-resetting type single-pole double-throw (SPDT) pushbutton switch, display 2 is contained on timing control enclosure box body 1 panel, power switch S ₁, control knob S ₂Be contained on the timing control enclosure box case control knob S ₂The moved end connects the single-chip microcomputer input end, normally-open normally-close end one end ground connection, and a termination positive supply, single-chip microcomputer output terminal also link with the aforesaid hummer input end that is contained in the box body.

The principle of work of this device is: be installed in that display on the timing control enclosure panel limits the whole audience 30 minutes and 10 seconds that each team member's time in the court is limited, the mode with countdown showed, and the zero-time of timing is by control knob S ₂Control is whenever S ₂The moved end throw end once by opening to often, promptly equal to pulse signal of single-chip microcomputer input, this device also is furnished with the software program that the timing at real racetrack need design, and presses self-resetting type single-pole double-throw (SPDT) button S the first time ₂, whole audience limiting time promptly on display since countdown in 30 minutes, when both sides team member by 1,2,3 ... when number order is entered the court, whenever go up a team member and click S ₂, display promptly from countdown in 10 seconds, shows player in's number simultaneously, arrive 10 seconds, software program promptly sends signal by computing machine to hummer, hummer rings, team member's number adds 1, as less than 10 second the player in promptly hit a ball, press S ₂Once, countdown was restarted from 10 seconds, and it is constant that team member's number shows, gave the team member chance of once batting once more, under the situation that player in's batting is hit off the target less than 10 seconds, as continuously by 2 S ₂, then countdown in 10 seconds starts, and shows next striker's number.When whole field time to 30 minute, hummer sends chimes of doom.This device can be provided with the figure place of display as required, be equipped with corresponding software programs again, can realize limiting functions such as countdown, the demonstration of player in's number, the demonstration of both sides team member's score situation, power switch S such as whole limiting time countdown, player in's hitting time ₁Can play a part simultaneously to have a power failure and restart total system and reset.

The croquet referee adopts the timing of this device very convenient on the field, only need control by a button, can self-clocking also show, it is inaccurate to have changed original manual time keeping, loaded down with trivial details situation, and this device can be equipped with different software programs and corresponding display figure place as required to show limiting time, player in's number, two teams' score situation etc. intuitively, and playing conditions is shown on score indicator at a glance.
