Thus, whenever a time signal generated by the movement is applied to the central control unit 10 every time, the program embedded in the central control unit 10 is driven and operated according to the control flow.

In this case, the day and night detection unit 20 generates a specific signal so as to distinguish between day and night, which is determined to be daytime when a light intensity of a predetermined intensity or more is detected by detecting a light intensity using a photo sensor. Each signal is applied to the central control unit 10 so that it is determined to be a night when a luminance of less than a predetermined intensity is detected.

Then, the central controller 10 first determines whether the current time at which the time signal is input is at any time during the day or night by using the signal input from the day / night detection unit 20, and then changes the control according to the determination result. To do.

That is, the cuckoo model, which is found to be day, is moved forward, and then "Cuckoo" sound is reproduced by repeating the number of times corresponding to the time number of the time signal.

A switching transistor Ql is provided to which a resistor R12 for adjusting the volume of output sound is connected. A capacitor C7 is connected between the collector terminal and the power supply terminal of the switching transistor Q1. Can be configured by connecting a speaker in parallel with (C7).

According to a preferred embodiment of the present invention configured as described above, a clock oscillator having a crystal oscillator (CR2) and capacitors (C1, C2) provides an oscillation clock (CLOCK) of 32.76 KHz, and the microcomputer (MICOM) U1 is controlled by a program built in.

When the time signal from the movement is applied to the RAO and RTCC terminals of the MICOM U1, the RTCC (REAL TIME COUNTER REGISTER) value in the MICOM U1 is increased by +1. Increases. In the present embodiment, when the timing signal is transitioned from a high state to a low state, it is made to be active.

Thus, when the active signal (ACTIVE SIGNAL) is applied from the movement, the MICOM (U1) receives the photo sensor output of the day and night detection unit 20 through the RA1 terminal, night and day When it is determined, it is determined whether it is received at the RA1 terminal, which is night or day. If the RA1 terminal is "HIGH" state, it is recognized as day and the RB5 terminal is "high" state. By outputting " ON " the switching transistor Q4, the motor MA for driving the cuckoo model is operated in the forward direction.

Next, the outputs of the RB1 and RB2 terminals of the MICOM U1 are controlled to output a signal corresponding to a "click" sound and to be applied to the speaker SPEAKER through the switching transistors Q1 and Q2. Cuckoo "is to play sound.

At this time, the number of the reproduced " cuckoo " sounds is output as many times as the number stored in the RTCC of the MICOM U1. In the present embodiment, the resistor R5 and the capacitor C4, C9 and C6 are for giving Vibration and Echo to the sound to be reproduced, and the magnitude of the reproduced sound is adjusted as the resistor R12.

In the present embodiment, when the "Cuckoo" sound is reproduced, the transistor (Q3) connected to the RB3 terminal of the MICOM (U1) is operated for a time corresponding to "tight", and the tail of the cuckoo model is shaken for a predetermined time. In order to make it possible, a control signal is generated as shown in the timing diagram of FIG.

Through this process, after the reproduction of the "Cuck" sound, the control signal is generated at the RB5 terminal of the MICOM U1 as shown in the timing diagram of FIG. By operating the motor (MATOR) for driving the cuckoo model (MA) in the reverse direction. In the figure, resistors R9 and Rl0 are for adjusting the output of the motor MA connected to the body of the cuckoo model.

After reproducing the "Cuckoo" sound and driving the motor (MA), a signal that can trigger the MELODY IC (U2) connected to the RB4 terminal of the MICOM (U1) (TRIGGER) ("ACTIVE" LOW "to output a predetermined melody sound signal through the resistor R19, thereby providing a speaker drive circuit including the resistor Rl1, the switching transistor Q1, and the capacitor C7. In operation, the predetermined melody is output to the speaker SPEAKER. In this case, the resistor R19 is a resistor for controlling the size of the melody sound and impedance matching (IMPEDAMCE MATCHING).

The microcomputer MICOM U1 checks the LED output state of the melody generating IC U2 while the melody sound is generated by a program therein so that the LED output of the melody generating IC U2 is " high " ", The switching transistor Q6 is operated through the RB7 terminal of the MICOM U1 to drive the motor MB which performs the music box ORGOL function.

When the LED output of the melody generating IC U2 becomes " low ", the switching transistor Q6 is turned off (0FF) to stop the operation of the motor MB.

On the other hand, when the time signal from the movement (MOVEMENT) is applied, if the RA1 terminal of the MICOM (U1) is "low" state, the current time is recognized as night, and the new time again Transitioning to a state of monitoring whether or not a signal is inputted, it prevents a series of operations as described above until a new timing signal is input from the mover.

4 is a flowchart illustrating a control process of operating the clock clock by using the control circuit of the present invention.

As shown in the figure, first, the microcomputer U1 at power-on System initialization such as is made (101). Then, the microcomputer U1 continuously monitors the terminals RAO and RTCC to which the time signal from the movement is input (103). When the time signal is input, the clock chime of the RTCC is locked. chime) +1 to increase the count (105). In addition, the state of the input terminal RA1 is read to determine whether the current time corresponds to night or day (107). Do not

On the other hand, if the current time is found to be low, the output terminal RB6 is controlled so that the cuckoo model moves forward by a predetermined distance (109).

Then, the output terminal RB2 and the output terminal RB3 are immediately controlled to output a "cuckoo" sound, and the cuckoo model, which is moved forward, shakes its tail in accordance with the cuckoo (111). The number of times is repeatedly output by the clock chime (C1ock chime) count number of the RTCC, so that the user can recognize the current time by looking at the cuckoo or the cuckoo's shaking tail.

Thus, after the cuckoo output and the cuckoo tail shaking operation are performed by the corresponding count number, the cuckoo that has been moved forward is returned to the original position by controlling the output terminal RB5.

Subsequently, the output terminal RB4 and the output terminal RB7 are controlled to generate a melody sound for a predetermined time and to perform an ORGOL operation (115).

After the above operation is completed, it is necessary to check whether the clock chime count value currently set in the RTCC has a value equal to or greater than 12 (117). Thus, if the present count value is less than 12, the process proceeds to the timing signal input standby step 103 again to monitor whether the timing signal is applied from the movement (103 to 117). Repeat).

On the other hand, if the clock chime (C1ock chime) count value currently set in the RTCC is set to a value equal to or greater than 12, the process proceeds back to the system initialization step 103, and after the RTCC is initialized, It is to repeat the entire process (101 to 117).

In the present invention, through such a control process, the one-chip microcomputer U1 adopted can be controlled collectively, which greatly simplifies the hardware configuration, and selects a set function and performs a function through a software change. It can be easily modified to maximize control and use efficiency.

Therefore, the present invention, which is constructed and operated as described above, employs the microcomputer control system to collectively control various functions, thereby simplifying the configuration circuit, reducing the material cost and manufacturing cost, as well as the control and use efficiency. It has the effect of maximizing and improving operational reliability.
