SUMMARY OF THE INVENTION An object of the present invention is to provide a method capable of locking and unlocking a safe door by operating a device having the above-described configuration by a program embedded in the microcomputer.

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

2 is a flowchart of a program for explaining the operation of the present invention. When the power is input, the microcomputer 1 enters the self-diagnosis mode consisting of steps 101 to 110, first outputting a key sound to the buzzer 5, and at the same time, the display device 3 is turned on. After displaying the word "step 101", the word "SUN SAFE" is displayed on the display device 3 together with the key tone (step 102). At the same time, the key tone is output to the buzzer 5. While displaying the word "TEST" on the display device 3, the microcomputer 1 diagnoses the display device 3 and Y pyrom 2 (step 103.) When the microcomputer 1 finishes self-diagnosis, After outputting a key tone to the buzzer 5 (step 104), the word " Test " displayed on the display device 3 is erased, and the display device 3 is " informed " ty-EEP "is displayed (step 105). In step 106, the password stored in EPI rom 2; Read parity 1, 2 and calculate parity based on the readout values 1. Use 1, 2 as password storage address of YPIROM (2) and 3, 4 as master number storage address The storage format is:

2nd

1st address

In addition, parity calculation is as follows.

Parity 2 = Digit 6 + Digit 5 + Digit 4

Parity1 = digit3 + digit2 + digit1

The microcomputer 1 compares the parity value calculated using the passwords recorded at addresses 1 and 2 of the Y. pyrom 2 with the parity value in the Y. pyrom 2 (step 106). In addition, after displaying the word "Good" on the display device 3 and enters the weighting mode (step 107). At this time, if the parity value in the Y pyrom 2 is 0 (step 108), an error sound is output to the buzzer 5, and the word “d-Err” is displayed on the display device 3, and then a holt is displayed. Enter the mode (step 110). If the parity value in the Y pyrom 2 does not match the calculated parity value, an error sound is generated through the buzzer 5 and the word “r-Err” is displayed on the display device 3 and then the holt is displayed. Enter the mode (step 109).

After the self-diagnosis mode of the microcomputer 1 is finished, it enters the D-mode and the M-mode. The D-mode and the M-mode consist of steps 112-132. The microcomputer 1 releases the weighting mode or the holt mode when the key is input (step 112), and determines whether the star art key (S key) is pressed (step 113). The microcomputer 1 determines whether the display key D key is pressed through the button 4 (step 114), and if it is determined that the display key is input through the button 4, the buzzer makes a buzzer sound. While outputting through (5) (step 115), the password currently stored in the ypyrom 2 is read out and displayed on the display device 3 (step 116), and the system enters the holt mode (step 117). If the microcomputer 1 recognizes that the display key is not input through the password key button 4 in step 114, it is determined whether the memory key M key is pressed (step 118) and the password key button 4 is pressed. When the memory key is input, it is determined again whether it is in the program (PGM) mode (step 119). If it is in the program mode, the new password is recorded in the ypyrom 2 (step 120) and the new password is read out from the ypyrom 2 again. (Step 121) and compares whether the recorded password matches the password entered through the button 4 (step 122). As a result of the comparison, if the value recorded in the ypyrom (2) matches the value entered through the button (4), the new password is correctly recorded in the ypyrom (2). The word "In" is displayed on the display device 3 at the same time as the output (step 123), and the new password is displayed on the display device 3 (step 124). If the value recorded in the ypyrom 2 in step 122 does not match the value entered through the button 4, an error sound is output through the buzzer 5 and the display device 3 displays " In-Err " Display is displayed (step 125) and enters the Holt mode (step 126). If the star art key (S key) is inputted via the password key button 4 in step 113, the microcomputer 1 determines whether the star art key has been pressed 16 times within 3 minutes (step 127) and within 16 minutes. If it is determined that the star art key has been pressed more than once, a warning sound is output for three minutes through the buzzer 5 (step 131), and then the holt mode is entered (step 132). If it is determined in step 127 that the Star Art key has been pressed 16 times or less within 3 minutes, the microcomputer 1 sets the S-mode and initializes it by setting 10 seconds (step 128). Subsequently, after generating the key sound through the buzzer 5, the word " Ready " is displayed on the display device 3 and ready to accept all the keys (step 129). Enter the weighting mode (step 130). In step 118, the microcomputer 1 enters the S-mode when it is determined that the memory key is not pressed.

Figure 2 (c) shows a flow chart for the S-mode operating state of the operational flow according to the present invention. Steps 133 to 147 form an S-mode. When the microcomputer 1 recognizes the S-mode (step 133), it determines whether the password key is input via the button 4 (step 134), and when the password is input, accepts the password (step 135). ) If all six digits of the password are entered (step 136), the entered password is compared with the password read out from EPI rom (2) (step 137) to determine whether the two passwords match (step 138). The sound is sent through (5) and the word “Open” is displayed on the display device 3. (Step 139.) The microcomputer 1 then drives the solenoid 6 for about 3 seconds to unlock the safe door. If it exceeds 3 seconds (step 141), the safe door is locked (step 141) by not driving the solenoid 6 (step 147).

If the two passwords do not match in step 138, the microcomputer 1 is set to the program (PGM) mode and initialized by setting 5 seconds at the same time (step 142), and enters the weighting mode (step 145).

In addition, if it is determined in step 133 that the microcomputer 1 is not in the S mode, the microcomputer 1 enters the holt mode (step 146). If the password is not entered in the step 134, the weighting mode is entered (step 143). If not entered, the weighting mode is entered (step 144).

Figure 2 (d) shows a flow chart for the weighting mode operating state of the operation flow in accordance with the present invention. Steps 148 to 156 form a weighting mode. Step 148 is a step of time up-date, which is a process of continuously initializing the time setting.

In step 149, it is determined whether the operating state of the system is in the program (PGM) mode or the S-mode, and in the case of the S-mode, it is determined whether the 10 seconds that were initialized in step 128 have elapsed (step 150), and when 10 seconds have elapsed. The device 3 displays the word " OFF " (step 153) and then enters the Holt mode (step 156).

If it does not exceed 10 seconds, the key is checked (step 151) and it is determined whether the key has been entered, and if not, go to step 148, and if so, go to step 112 (step 152). In the case of the program (PGM) mode in step 148, it is determined whether 5 seconds that have been initialized in step 142 have elapsed (step 154). If 5 seconds have not elapsed, the process proceeds to step 151. At the same time as the output of the display, the display apparatus 3 displays the character " d-Err " (step 155).
