44、h图 1. 计时器的工作框图3.单位电路模块设计3.1 标准信号源产生脉冲信号的电路很多,例如由集成门电路构成的多谐振荡器,由555 定时器组成的方波发生器等。由于该标准信号源要求频率稳定性及输出信号精度比较高,故采用由CD4011与非门( CMOS)电路及晶体原件组成的多谐振频率的信号如图2所示,晶振的标称频率为32768Hz 。由于石英晶体的选频特性非常好,只有其串联谐振频率的信号才最容易通过,而其他频率会被晶体大大衰减,所以电路在满足震荡的条件下,其输出频率仅取决于晶体的标称频率,与其他原件参数无关。电路中的电阻 R是保证 G1门工作在线性状态而加入的,电容C抑制告辞谐波,以保证输出频率
45、稳定。G3门是为了改善输出波形质量,增加带负载能力而加入的缓冲级。3.2 分频器由于 f=32768Hz 频率比较高,为了得到低频信号且又能满足定时要求的脉冲,可采用CD4040二进制计数器 / 分频器进行分频。 CD4040 是由 12 个 T型触发器组成的串行二进制计数器/ 分频器。复位端高电平有效, 2 个输入端,一个是时钟 CP , 一个是复位清零端,有 12 个分频输出端 Q1-Q12,最大分频系数为 212=4096。n 位二进制计数器的最高位输出信号的频率fn与计数器脉冲频率fcp的关系为 fn=fcp/2n 。现选择 12 位异步二进制计数器 CD4040 , 则 CD4040
46、计数器最高位输出频率为 f12=f0=fcp/212=8Hz 电路如图 2, CR为清零端。12R1MCS32 76 8 HzC100pFG1G2G3foCPCrQ 11foCD 4 04 012G1G2G3R1100KD11 N 4 1 4 8C D 4 0 4 0CrQ 1 0 Q8Q7Q5CPC D 4 0 8 2C D 4 0 0 1fTfo图 2 标准信号源电路及分频器图 4 三分钟定时电路3.3 3分钟定时器该 电 路 是 本 系 统 的 关 键 。 n 位 二 进 制 计 数 器 的 输 出 状 态 与 计 数 脉 冲 的 个 数 关 系 为 :(N)D=2n-1Qn-1+2n-

69、C门输出的七段显示译码器74LS47 ,显示器采用共阳极七段LED数码管。其中 R是限流电阻,即当 74LS47输出为低电平时, 流入其输出端电流要小于74LS47的最大允许灌电流。 若 R过小,流入 74LS47的灌电流增大;若R过大,则 LED数码管太暗。一般R选择 200W 500W (在 5V电源下) 。CD4029通过控制输入端可构成二进制或者BCD计数器,它有 3 个控制端,即二进制 / 十进制转换 B/D,加/ 减转换 U/D和预置数 LD ,另外它还有 4 个置数端 D0-D3,4 个输出端 Q0-Q3,脉冲输入端 CP ,进位输入端 CI , 进位输出端 CO。CD4029具
70、有优先进位功能的四位二/ 十进制加 / 减计数器,进位功能可以根据加法和减法或者二进制和十进制来确定CP上升沿进行计数。电路如图 4 所示。由于 CD4029 无清零端,实现复位功能需要置数清零。译码器选用OC门输出的七段显示译码器 74LS47 ,显示器采用共阳极七段LED数码管。其中 R是限流电阻,即当74LS47输出为低电平时,流入 74LS47的灌电流增大;如果R过大,则 LED数码管太暗。一般 R选择 200-500 (在 5V电源下) 。3.5 复位电路根据设计要求,在每次通话之前一定要清零。当复位按键按下时,3 分钟定时电力和通话次数计数电路均被清零。如图6 所示。当 S(复位开
71、关)按下时, +5V电源同时加到 2 分钟定时器的清零端和通话次数的指数段,使其强迫清零。但由于二极管D1的存在, +5V电源加不到门电路CD4001的输出端,避免了 CD4001的损坏。另外。由于D2的作用,使得 3 分钟定时脉冲仅能加到3 分钟定时器的清零端和通话次数计数器的计数脉冲输入端,而传送不到通话次数计数器的置数端上来,从而实现了正常的计数。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 3 页,共 6 页Delegates, staff: Hello! in the run-up to the Spring Festival, we
