The present invention relates to a method and a device for driving a piggy bank, and more particularly, a timer function, a date arithmetic and display function, a saving amount display function, an opening date reservation function, a saving amount reservation function, and a password reservation of a piggy bank having a predetermined internal space. The present invention relates to a method and apparatus for driving a piggy bank so that a piggy bank can be automatically opened when a date reserved or a low amount of money by the user becomes a reserved amount and a password is input by the user. Most of the piggy banks have a sealed space with a predetermined area, and only one side of the current-carrying opening is formed. Therefore, when a coin is different from one coin box and the coin is to be taken out, the piggy bank must be disassembled. There was this.

Conventionally, in order to solve this problem, a money box having an opening / closing device capable of taking out coins collected therein has been developed, but in this case, a locking device for opening / closing the opening / closing device is locked and determined by a predetermined key. It is difficult to store and the cloning of the keys is easy so that the opening and closing of the money box can be done easily by others, and it is not equipped with the accumulation function of the coins collected inside the money box so that the total amount of coins collected is not known at all. There was a problem.

An object of the present invention is to allow a user to continuously accumulate and display the amount of coins stored, and at the same time a desired amount is collected, or when a deposit is made for a certain period of time, or when a user enters a random password. The present invention provides a method and apparatus for driving a piggy bank, which can be automatically opened when the password is inputted in memory.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the apparatus of the present invention includes: a rectifying unit 2 for rectifying a predetermined AC voltage input from the power supply unit 1 into a DC voltage having a constant voltage; It consists of mode changeover switch (SW1), fast-up switch (SW2), slow-up switch (SW3), alarm switch (SW4), reservation switch (SW5) and reset switch (SW6). A key input unit 3 for selectively generating each of them; A coin input detector 4 for detecting how much coins are installed at the coin input port of the lower barrel; A reservation function selector (5) configured of one key switch (SW7) for selecting a reservation function; A matrix unit 6 for applying the outputs of the key input unit 3, coin input detector 4, and reservation function selection unit 5 to the microcomputer 7, respectively; A microcomputer 7 which receives signals input differently from each unit and performs overall control of the money box by a predetermined program; It consists of seven segment driving IC (U3), digit driving determination IC (U4), and several transistors (Q1-Q8), and several digits (D1-D8) by a predetermined signal output from the microcomputer (7). A liquid crystal display driver 9 for driving the liquid crystal display unit 8 including the AM / PM display light emitting diodes L7 and L8; It consists of a decoder U5 that decodes the microcomputer's output signal, an output driver IC U6, and an inverter I1, and displays various operating functions as well as light-emitting diodes L1-L6 and alarm signals. It is characterized in that it is configured by interconnecting the functional part drive unit 10 for selectively driving the generator 11 and the lock control relay RL1.

As shown in FIG. 2, the method of the present invention includes an initial value 1 setting process (S1) for initializing the microcomputer 7 when the power source is turned on; An initial value 2 setting process (S2) for keeping the microcomputer 7 in operation standby state; Detecting whether the mode conversion switch SW1 is input and performing a mode selection subroutine accordingly (S3); Performing an alarm subroutine by detecting whether the alarm switch SW4 is "on" (S4); Detecting whether or not a coin is input and performing a cumulative subroutine (S5); Detecting a "on" count of the alarm switch SW4 and performing an alarm subroutine corresponding thereto (S6); Detecting a "on" count of the mode conversion switch SW1 and performing a mode selection subroutine corresponding thereto (S7); And a step (S8) of detecting whether the reservation switch SW5 is " on " and the " on " number of times, and performing a reservation subroutine corresponding thereto.

The mode selection subroutine stores the number of times the mode conversion switch SW1 turns "on" as shown in FIG. 3 (a) (b). If it is 2, it displays the current date. If it is 3, it displays the amount saved up to the present. If the number 4 is "on", it displays the password function, and then the key switch (SW7) is entered. If fast and slow up switches SW2 and SW3, which are correction switches, are input, correct the respective values with the current values. Otherwise, if the current time is the alarm time, the alarm signal generator 11 detects whether the current time is the alarm time. If the current time is not the alarm time, the alarm signal is generated for a minute, and if the current time is not the alarm time, it sequentially detects whether the current date is the opening date of the savings account, the accumulated savings amount to the present ≥ the reserved savings amount or the inputted password is the reservation number. When satisfied it is to drive the relay (RL1) opening the bank and press the reset switch (SW6) when made of a thin phase back to the first process.

In addition, the alarm subroutine stores the "on" count of the alarm switch SW4 as shown in FIG. 4 (a). If it is one or more times, the alarm subroutine clears the "on" count of the alarm switch and resets the initial value of the microcomputer 7. Returning to the setting process (S1), if the number 1 is " ON ", the alarm time is displayed on the liquid crystal display 8, and if a correction switch is input, the alarm time is corrected. It returns to the initial value 2 setting process (S2) of (7). In addition, as shown in (b) of FIG. 4, the cumulative subroutine detects whether coins entered through the coin inlet of the piggy bank are 10, 50, 100, and 500 won, respectively, and accumulates the amounts of the coins. It is made up of steps that add to the amount.

On the other hand, the reservation subroutine is " on " of the reservation switch SW5 when the reservation switch SW5 is " on " while the key switch SW7 is ON, as shown in Fig. 4C. If the number of times is detected, the date reservation function is displayed on the liquid crystal display unit 8 in the first case, the low amount reservation function is displayed in the second case, and the password reservation function is displayed in the third case, and each reservation is made when the correction switch is input. After inputting the correction value according to the function, the process returns to the initial value 2 setting process (S2) of the microcomputer 7 as in the case where the correction switch is not inputted. The process returns to the initial value 1 setting process (S1) of (7).

Referring to the effects of the present invention as follows.

First, when the power supply voltage is applied to the piggy bank of the present invention, the bridge diode is the AC voltage output from the power supply (1) consisting of a transformer (T), the power switch (S1) and the input voltage switching switch (S2) of 110 / 220V The rectifier is composed of (BD), regulator (IC1) and condenser (C1, C2) and the like rectified to a DC voltage of a constant voltage and applied to each part, the microcomputer (7) performing the overall control function by a predetermined program at this time After the initial value 1 setting process (S1) for initializing the program and predetermined data in the self) is performed, the initial value 2 setting process (S2) for maintaining the operation standby state is performed. All functions (ie reservation function and alarm sound function) can be performed.

If the user operates the mode switching switch SW1 in the key input section 3 and inputs it to the microcomputer 7 through the matrix section 6, the number of times the " ON " If it is "on", the current time is displayed on the liquid crystal display (8), and if it is "on" twice, the current date is displayed. If it is 3, the accumulated amount so far is displayed and the number 4 is " If it is "ON", the password function is displayed, but if it has been "ON" more than five times, the "ON" count of the mode change switch (SW1) memorized for the first time is cleared.

To explain this in more detail, for example, when the mode conversion switch SW1 is turned “on” twice, first, since the “low” signal is input to the input terminal P1.0 of the microcomputer 7, the microcomputer is input. In (7), it is determined that the display mode is the date, and a predetermined output signal is generated through the output terminal P2.3 thereof, and this signal is transmitted through the input terminal 1A4 of the decoder U5 in the functional part driving unit 10. After being input and decoded, it is output from its output terminal 1Y4, and is input through the input terminal 4B of the output driving IC U6, and is output as a "low" signal through its output terminal 4C. The diode L4 is turned on so that the user can easily recognize the date display mode by the lighting state of the light emitting diode L4.

At this time, the output terminals P0.4-P0.7 of the several output terminals P0.0-P0.7 in the microcomputer 7 are among the digits D1-D8 installed in the liquid crystal display 8. It is connected to the input terminals AC and G1 of the digit drive determination IC U4 for determining which digit to drive. The output terminals P0.0-P0.3 are the seventh segment of the digit. Predetermined output through the output terminals (P0.0-P0.7) of the microcomputer 7, since it is connected to the input terminal (AD) of the seven-segment driving IC (U3) for determining which segment to drive. The date is displayed on the liquid crystal display 8 by the signal. For example, if the mode conversion switch SW1 is turned "on" once to display "12: 00" on the liquid crystal display unit 8, the output terminals Y0, Y2, and Y3 of the digit drive determination IC U4. Since Y5, Y6 and Y7 output the "low" signals, several transistors Q1, Q3, Q4 and Q6-Q8 connected to the bases are driven to light up the LED L7 for the afternoon display. Digits D1, D2, D4, D5, and D6 are driven.

When a predetermined digit is selected among the several digits D1-D8 as described above, predetermined output voltages are generated at the output terminal AG of the seven-segment driving IC U3, respectively, so that the digits D1 and D2 of the liquid crystal display 8 can be used. A predetermined number (that is, 12: 00) appears in, D4, D5, and D6.

In addition, if the mode switch SW1 is turned "on" 2 and 3, the liquid crystal display 8 displays the date and the total savings of coins put in the money box by the same operation as described above.

On the other hand, when the user desires to modify the reservation savings, etc. desired by the user, the key switch SW7 must be "on" as shown in FIG. 4 (c) so that a "low" signal is applied to the input terminal TXD of the microcomputer 7. After inputting, according to the number of times the key switch SW7 is "on", the reservation function of the date, the reservation amount of the low amount, and the reservation function of the password are performed. For example, the key switch SW7 is set to "2". ON to select the low value reserve function, and then operate the correction switch fast up switch SW2 and the slow up switch SW3 to set the low amount to the desired amount.

In other words, every time the reservation switch SW5 is turned "on", a "low" signal is input to the input terminal RXD of the microcomputer 7, and the microcomputer 7 receives a money box when a single "low" signal is input. The reservation function of the open date is performed, and when the second time is entered, the reservation function of the low amount is performed, and when the third time is entered, the reservation function of the password is performed. For example, if the reservation switch SW5 is "on" three times while the key switch SW7 is "on" to reserve a password, a "low" signal is input to the input terminal TXD of the microcomputer 7. In the state, since the "low" is input three times to the input terminal RXD, the microcomputer 7 performs the password reservation function. In this case, the fast-up switch SW2 and the slow switch are the same as in the low-cost reservation function. The password is corrected to the number desired by the user by operating the up switch SW3.

In addition, the cumulative coins of the coin input through the coin inlet is continuously performed since the clock function is activated after the power input, which is a switch in the coin input detector 4 whenever a predetermined coin is input through the coin inlet ( It is detected by S500, S100, S50, and S10 how many coins are input and input through the input terminals P1.4-P1.7 of the microcomputer 7, so that the calculation function of the microcomputer 7 can be used. Accumulate by

That is, the total amount of coins previously put in the microcomputer 7 is stored, and the amount of coins inputted through the coin input detector 4 is recognized and accumulated, respectively, as well as the present value through the liquid crystal display 8. Display the total savings.

For example, if the amount of money put into a predetermined money box is 15,000 won, but a coin of 500 won is put through the coin insertion hole so that the switch S500 of the coin input detecting unit 4 is "on", Since the "low" signal is applied to the input terminal P1.4, the microcomputer 7 receives this signal and recognizes that the currently put coin is 500 won and adds it to the previous amount, and then adds the amount to the liquid crystal display unit ( 8) through a predetermined number (that is, 15,500 won), so that the user can easily recognize the cumulative current while he is currently saving in a predetermined money box.

In addition, when the alarm switch SW4 is turned "on", a "low" signal is applied to the input terminal P1.3 of the microcomputer 7, so that the microcomputer 7 receives liquid crystal through the liquid crystal display driver 9. The time for generating an alarm is displayed on the display unit 8. When the correction switch is input, the modified alarm time setting value is displayed on the liquid crystal display unit 8.

When the current time reaches the preset alarm reservation time, the microcomputer 7 generates a predetermined output signal to the output driving IC U6 through the decoder U5 of the functional part driver 10. When the "low" signal is output from the output terminal 8C of the output driving IC U6, the alarm in the alarm signal generator 11 is buzzed and BZ is driven to generate a predetermined alarm sound for 1 minute. When the user "offs" the alarm on / off switch S3, the generation of the alarm sound is blocked.

On the other hand, the opening of the piggy bank is when the current date becomes the reservation opening date of the piggy bank reserved above, or when the accumulated savings of coins stored in the piggy bank is more than or equal to the reserved saving amount or when the password is artificially input by the user. When the reservation number is the same, the "high" signal is output from the output terminal T1 of the microcomputer 7, so that the "low" signal is output from the output terminal 7C of the output driving IC U6, so that the solenoid RL1 is output. Since the lock of the opening and closing device not shown is opened, the coin can be easily taken out by opening the piggy bank when the desired date or desired amount and password are met without damaging the piggy bank.

As described above, according to the present invention, the coin is inserted into the coin when saving various coins in a piggy bank having a predetermined internal space, and the accumulated value thereof is displayed and the date, time, and alarm time are reserved. The function is performed so that the bank can be opened automatically when the reservation date for opening the bank is opened, or when a desired amount is collected in the bank, or when a password set by the user is set arbitrarily. It is a useful invention that can accurately know the amount of coins to be able to accurately control the amount of savings of coins until the desired date, as well as to prevent the release of the locking device from others in advance to further improve the reliability of the product.
