如图3所示，本发明的电路工作原理是：红外接收头U7接收到外部遥控器发来的红外预置信号并经解码后，送入U1的INT0输入口，经U1进行识别处理，从输出口P00～P05分别送到U2、U3进行数字译码和锁存，再经U4、U5进行电流驱动，并由电阻R1～R14限流，然后点亮十分钟位造型数码超高亮显示屏L1和分钟位造型数码超高亮显示屏L2，接着由后续的启动信号使其开始倒计时闪烁显示，U1同时从P06口输出高电平，使TR2导通，点亮“-”号字符屏L3，指示出进行的是倒计时状态；到达零分钟后转为超时正向计时显示，U1使TR2截止和L3熄灭，并从P07口输出高电平，使TR3导通，点亮“+”号字符屏L4，指示出进行的是正向计时状态；以“分”为计时单位的造型字符超高亮显示屏L5经电阻R15限流，始终保持点亮状态；U1收到停止信号则停止内部计时，进而经U2和U3的控制作用使L1和L2显示屏数据停止不动；另方面，若按动x10分钟预置按键S4、x1分钟预置按键S3、手动启动按键S2、手动停止按键S1，相应的操作信号经U1识别处理后，实现与上述遥控器同样的控制功能；在“停止”之后若再执行“启动”操作，则不必重复进行“预置”，U1能调用原先已预置的时限数据进行新一论的显示和运作U1内部同时监测时刻点，在相应时刻点诸如倒计时的开始处、剩余3分钟处或1分钟处、到达0分钟处和转为正计时后每分钟处，通过P10～017和P27端口把响应的语音寻址地址送到U6的A0～A8地址端口，在U6内部识别相应的语音音素并进行合成后，通过SP+和SP-双端口输出语音信号，经阻容网络C6、C7和R25、R26耦合，由电位器POT控制音量，送至U8的IN+和IN-输入端，进行功率放大后驱动喇叭发出提示语音。每一轮过程中的限时时间、所用时间或超时时间等数据由U1的P25和P26端口以串行方式送到U9进行停电不失性储存。在需要向计算机传送数据时，U1把记录在U9中的数据读出，然后通过通信端口RXD和TXD送到U10进行电平转换，再经通信插口COM向外部计算机传送。电容C4和电阻R22、手动复位按键S0分别产生上电复位和手动复位高电平，送至U1的RESET复位端实现系统复位，若U7收到的是外部遥控器发来的复位信号，则U1从P24口送出低电平，使晶体管TR1导通，引起C4放电，从而使U1的RESET复位端出现高电平而实现遥控复位。C17用作直流电源去耦电容，C18～C23分别用作集成件U1、U2、U3、U6、U9和U10的供电端去耦电容。As shown in Figure 3, the working principle of the circuit of the present invention is: the infrared receiving head U7 receives the infrared preset signal sent by the external remote controller and after decoding, sends it to the INT0 input port of U1, and performs identification processing through U1, from The output ports P00~P05 are respectively sent to U2 and U3 for digital decoding and latching, and then current driven by U4 and U5, and the current is limited by resistors R1~R14, and then the ten-minute digital super bright display is lit L1 and the minutes-shaped digital ultra-bright display L2, followed by a subsequent start signal to start the countdown and flashing display, U1 simultaneously outputs a high level from the P06 port, making TR2 conduction, lighting up the "-" character screen L3 , indicating that it is in the countdown state; when it reaches zero minutes, it turns into a timeout positive timing display, U1 cuts off TR2 and turns off L3, and outputs a high level from P07 port, turns on TR3, and lights up the "+" character The screen L4 indicates that it is in the forward timing state; the ultra-bright display screen L5 with "minutes" as the timing unit is limited by the current of the resistor R15, and always keeps on; U1 stops the internal timing when it receives the stop signal, Then, through the control of U2 and U3, the data on the display screens of L1 and L2 are stopped; on the other hand, if the x10 minute preset button S4, x1 minute preset button S3, manual start button S2, and manual stop button S1 are pressed, the corresponding After the operation signal is recognized and processed by U1, the same control function as the above remote control is realized; if the "start" operation is performed after "stop", there is no need to repeat the "preset", and U1 can recall the previously preset time limit Data display and operation U1 internally monitors the time points at the same time, at the corresponding time points such as the beginning of the countdown, the remaining 3 minutes or 1 minute, the arrival of 0 minutes and every minute after turning to positive timing, through Ports P10~017 and P27 send the corresponding voice addressing address to A0~A8 address ports of U6. After the corresponding phoneme is recognized and synthesized inside U6, the voice signal is output through the dual ports SP+ and SP-. The network C6, C7 is coupled with R25 and R26, and the volume is controlled by the potentiometer POT, which is sent to the IN+ and IN- input terminals of U8. After power amplification, the speaker is driven to issue a prompt voice. The time-limited time, elapsed time or overtime data in each round process are sent to U9 in serial mode through the P25 and P26 ports of U1 for power failure non-volatile storage. When it is necessary to transmit data to the computer, U1 reads the data recorded in U9, and then sends it to U10 through the communication ports RXD and TXD for level conversion, and then transmits it to the external computer through the communication port COM. Capacitor C4, resistor R22, and manual reset button S0 respectively generate power-on reset and manual reset high levels, which are sent to the RESET reset terminal of U1 to reset the system. If U7 receives a reset signal from an external remote control, U1 A low level is sent from the P24 port to turn on the transistor TR1, causing C4 to discharge, so that the RESET reset terminal of U1 appears a high level to realize remote reset. C17 is used as a DC power supply decoupling capacitor, and C18-C23 are respectively used as decoupling capacitors for the power supply terminals of the integrated parts U1, U2, U3, U6, U9 and U10.
