計(jì)分系統(tǒng)：
（1）分為“A隊(duì)”和“B隊(duì)”的“3分”，“2分”，“1分”各六個(gè)按鍵輸入部分，以及兩隊(duì)比分的LED顯示部分。在每次增加分?jǐn)?shù)的同時(shí)，“24秒”計(jì)時(shí)恢復(fù)為初始值，“12分鐘”計(jì)時(shí)暫停，等待比賽的繼續(xù)進(jìn)行
計(jì)時(shí)系統(tǒng)：
（1）比賽開始/繼續(xù)：當(dāng)“比賽開始/繼續(xù)”鍵按下后，“24s”和“12分鐘”計(jì)時(shí)器開始倒計(jì)時(shí)；
（2）手動(dòng)24s復(fù)位：當(dāng)“24s復(fù)位” 鍵按下后，“24s”倒計(jì)時(shí)恢復(fù)初始值，“12分鐘”倒計(jì)時(shí)暫停，等待比賽的繼續(xù)；
（3）比賽暫停：“比賽暫停”鍵按下后，“24s”倒計(jì)時(shí)和“12分鐘”倒計(jì)時(shí)均暫停，等待比賽的繼續(xù)進(jìn)行；
（4）自動(dòng)增加比賽節(jié)數(shù)：當(dāng)“12分鐘”倒計(jì)時(shí)完成后，判斷當(dāng)前節(jié)數(shù)是否為最后一節(jié)，若不是，則節(jié)數(shù)自動(dòng)增加，并“12分鐘”和“24s”均恢復(fù)默認(rèn)值，等待下一節(jié)比賽的進(jìn)行。
