The software section of tae kwon do electrometer subsystem is formed by being poised for battle table manager, information for the game database and three independent sectors of match master control system.
As shown in figure 13, match control system software comprises four functional modules, and the time of being respectively is provided with module, and the total information display module is pressed key processing module, every innings of information display module.Time comprises that fixture setting and time of having a rest are provided with in the middle of module is set.Use two edit boxes to be used for client's time and import, use two global variable game_time and rest_time to store this two times at main interface then, be used for the use of main window.The total information display module mainly comprises: opposing teams' name, and school, game status, time showing, score show that warning, point penalty show.By key processing module mainly is both sides' information button and match control button.The information button is that both sides' score, foul, point penalty are added and subtracted.Match control button mainly is to realize suspending in the match, continues, and finishes, and function such as reset.The realization of information button can be made amendment to variables corresponding by key response, upgrades in the static text at main interface then.Every innings of information display module comprises that score shows, warning, point penalty show and sideline judge's button shows.Score demonstration and warning, point penalty show with total demonstration similar, just the variable difference.Sideline judge's button shows and can show for 1 second at display module with picture simultaneously in real time to sideline judge's key response, reminds the user, also can carry out record to every innings of each judge's touch potential, judges whether judge or machine go wrong.
The information for the game database is made up of three tables: the Information table---record match sportsman name, group, feather weight, sex, school.This shows to be the initial information table after the competition data importing that information wherein is basic registration information.Round table---wheel number in the group, red name school, blue or green side's name school, rank, group, sex, the first round such as arranges number at information.This table for system with same levels, group, the rank results of the antagonism group of sex in calculates the at most rounds of match of this group, is saved to wheel number in the group, shows use for finalround.Finalround table---red name school, blue or green side's name school, rank, sex is finally arranged competition sessions, victor's name, school.This table is poised for battle table for the final match of all ranks of a full match after arranging according to each round of group table, group, sex.Promptly can be used as match table poised for battle after this table is derived and be issued to the leader of every team.After every game finished, main program can be revised victor's name and school, and it is inserted in the table poised for battle of next round.
The system platform that list management system poised for battle is to use Netbeans software and Java language to write.Can control it database is carried out direct bookkeeping.Major function is as follows: add player information: can import the excel table, information storage is in the information table.Arrange and be poised for battle table: the information table is handled, generated last finalround table at random, and be presented on the screen.Can begin several byes in the match of taking turns according to the different few groups of number that make of round in the round table during arrangement, so just can guarantee that last takes turns match is all other finals of level.Empty and be poised for battle table: empty round table and finalround table.Derive and be poised for battle table: the table poised for battle that can derive any effective number among the finalround.Table is poised for battle in the inquiry change: the information among the information is inserted deletion, operations such as modification.Generate and derive the system of battle formations: be that the unit generation is tree-shaped to the system of battle formations with the group, make the match process more clear.
In addition, list management system poised for battle also is provided with two different rights: one is administration authority, is poised for battle table for the tournament director to competing and manages, and above all functions are open to it; Another is reporter's authority, for related personnel such as reporters by LAN inquiry match dynamically, table is poised for battle in its open inquiry, derives and is poised for battle table, derives functions such as the systems of battle formations.
The course of work of the present utility model is: by written challenge to war editing machine being imported each team member of team participating in competition information, use generates the written challenge to war at random automatically to written challenge to war arranging functional and deposits to database before the match.Open main control software, set fixture, the time of having a rest, competition sessions import match and are poised for battle table, and output game status video is on TV, and the sportsman takes the field.The sideline judge holds sideline judge's controller station in field week during match, uses wireless telecommunications and host computer communication to carry out the transmission of real-time match score information, and the plate umpire controller links to each other with computer by serial ports, and each sideline judge's marking situation is reached computer.System writes down result of the match (time and the number of times that comprise score and foul) automatically after the end of match, upgrades game under the laggard row of the written challenge to war.
