Description

[Detailed Description of the Invention] [Industrial field of application] The present invention memorizes a personal identification number set by a user, and unlocks when the input number and the stored personal identification number match. It relates to a personal identification number input type locker device.

[Problems to be solved by conventional techniques and devices]

Conventionally, the above locker device has been widely used, for example, as a rental locker for sports facilities, and this type of device is provided with an operation unit such as a numeric keypad on the locker door table and the like, and the input of a password for unlocking operation is performed. Is operated by key input from the operation unit. For this reason, the user does not need to store the key etc. just by remembering the personal identification number,
Further, there is an advantage that inconvenience due to loss or theft of the key can be avoided.

By the way, in this type of locker device, it is initialized when the power is turned on, and is ready for setting a personal identification number. However, the locker device that has been used once needs to delete the set personal identification number for the next use, which causes the following problems.

For example, in the case of centralized control of many lockers, the power is shut off all at once for a specified time to erase the PINs of all lockers, so lockers for long-term rental and short-term rental are available. There is a problem that it is not possible to individually deal with a plurality of locker devices, such as by providing a locker for each.

Further, in the case where the power is turned on by using a card as disclosed in Japanese Utility Model Laid-Open No. 62-193066, it is possible to remove the card, turn off the power, and erase the personal identification number. Although it can be done, there is a problem that it takes time if the card is left without being removed after unlocking.

In addition, there is a device in which the password is deleted once it is unlocked, but in this case, the password must be set again each time the user performs the opening / closing operation several times. There is a problem that is bad.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the usability by automatically restoring the usable state even if the personal identification number input type locker device is used once.

[Means for solving the problem]

You can do it.

 FIG. 2 is a block diagram of the embodiment.

The control unit 16 is composed of a microcomputer including a RAM, a ROM, an I / O port and the like (not shown), and controls each unit based on a control program stored in the ROM as described later.

The DIP switch 17 is for externally setting the time count timed by the control unit 16, and the control unit 16 reads the state of the DIP switch 17 and stores the set time in the memory.

The time counting operation in the control unit 16 is performed using a timer interrupt generated inside the microcomputer. That is, the number of timer interrupts generated in a constant cycle is counted using a counter preset in the memory, and the number of interrupts corresponding to the set time set in the DIP switch 17 is compared with the count value of the counter. The end of time measurement is detected by.

The solenoid drive circuit 18 turns on and off the current supplied to the solenoid 12 from a power source (not shown) by the ON / OFF signal from the controller 16, and the LCD drive circuit 19 controls the controller 1
The liquid crystal display unit 23 is driven based on the output data from 6. The number input from the numeric keypad 21 at the time of setting the personal identification number and the unlocking operation is displayed on the liquid crystal display unit 23 via the control unit 16 and the LCD drive circuit 19.

FIG. 3 is a flow chart showing the control flow of the control unit 16, and the operation will be described based on this figure.

When the control program is started, it is judged whether or not there is a secret code stored in the memory (step S ₁ ), and if there is a secret code, it is judged whether or not the state of the microswitch 13 is locked (step S ₁ ). S ₄ ).

If the password is not stored in the memory,
The input states of the numeric keypad 21 and the set key 22 are monitored and waited until the personal identification number is input and the setting operation is performed (step S
_2), further sets the key number is input a predetermined number of digits (e.g. 4 digits) is input, and stores the entered personal identification number into the memory (Step S _3), a micro switch 1
It is determined from the state of 3 whether or not it is locked (step S ₄ ).

In this way, when it is detected from the state of the micro switch 13 that the locking operation is performed, the solenoid 12 is turned off.
Set to F and lock (step S ₅ ). Starts counting by reading the set time from the DIP switch 17 (step S _6, step S _7).

As described above, the registration of PIN locker completed is locked, the control unit 16 monitors the time-up of the presence and configuration time for number input from the numeric keypad 21 (step S _8, step S ₉ ), Depending on the case where the input of the number is detected before the set time is up and when the time is up before the number is input, the flow branches into the following two flows.

It makes a comparison with the case where (number input when before time is up) is input when the number input is detected and PIN in the memory (step S _10), the must match the similarly numbered inputs Presence / absence and time-up of the set time are monitored (steps S ₈ and S ₉ ). Further, in the case where the number entered and personal identification number match unlocked by a solenoid 12 to ON (step S _11), monitors the time-up condition and the set time of the microswitch 13 (Step S _12, step S _13).

When the locking operation before the time-up has been performed is detected, and lock by the solenoid 12 to OFF (step S _14), monitors the timeout of whether the set time of the similarly numbered inputs (step S _8, step S _9). Further, when the time is up before the locking operation is detected, clear the PIN number stored in the memory returns to the flow of (step S ₁₅₎ when the program starts.

(Time-up if the prior number input) number input is when time is up and wait state numbers entered without locked state (step S _16), number input is entered with the code number in the detected memory number Is compared with (step S ₁₇ ).

Then, if no match and number input and personal identification number becomes a waiting state of the similarly numbered inputs ((Step S _16), if they match clears the PIN number stored in memory At the same time, the solenoid 12 is turned on and unlocked (steps S ₁₈ and S ₁₉ ), and similarly to after the start of the program, it is in the standby state for the setting operation of the personal identification number for monitoring the input state of the numeric keypad 21 and the set key 22. Return (step S ₂ ).

Thus, if the interval is shorter than the set fixed time, the locker can be repeatedly used by using the same personal identification number set at the beginning. Also, when the unlocked state is reached after the elapse of a certain period of time, it is returned to the initial state in which the personal identification number can be registered. Further, since the set time can be freely set by the DIP switch 17, it is possible to divide the lockers according to the purpose of use in a centrally controlled locker group, etc., and set different use times for each classification. .

FIG. 4 is a block diagram showing a rocker device according to another embodiment. The same parts as those in FIG. 2 are designated by the same reference numerals and the description thereof will be omitted.

The apparatus of this embodiment is used, for example, as a locker for centralized control, and the control unit 16 'is composed of a microcomputer like the control unit 16 of the above embodiment, and the I / O is operated according to the control flow shown in FIG. A notification signal is output from the port to the central controller 5. As shown in FIG. 5, in this embodiment, the unlocking operation (step S in FIG.
₁₉ ) is eliminated and the notification and unlock detection (step S ₁₉ ′, step S ₂₀ ′) operations are performed.

That is, as in the above embodiment, when the time is up in the locked state (when the time up is before the number input)
To become a waiting state of the number input (step S _16), the inputted number and the personal identification number and is a match (step S _17), clears the PIN number stored in memory,
A notification signal is output to the central controller 5. (Step S ₁₉ ′) Then, based on the state of the microswitch 13, it is monitored whether or not the locker is unlocked (step S ₂₀ ′).

In this way, the central control unit 5 of the centralized control can notify the manager or the like that the user has returned by the notification signal.

Further, in this case, when the lock of the lock is released by the master key as described above and the tongue 11 is disengaged from the frame portion 20 of the rocker body by turning the handle 3, this operation is detected by the micro switch 13.

When this unlocking operation is detected, the operation returns to the standby state for the operation of setting the personal identification number for monitoring the input state of the ten keys 21 and the set key 22 (step S ₂ ), as in the case after the program is started, and the personal identification number is confirmed. It will be in the initial state where registration is possible.

[Effect of device]

As described above, according to the present invention, the personal identification number input type locker device is provided with a timer for measuring a preset constant time and a time setting means for setting the constant time to be locked, When an operation is performed, the above timer function is activated to start counting a fixed time, and when the counting of the fixed time ends, the stored PIN is invalidated and the PIN returns to the initial state where a new PIN can be set. Since it is possible to repeat the normal opening and closing operations within a certain time after the start of use of the locker, it is possible to reuse it even once it is used, so turn off the power supply. It is possible to obtain a locker device that is easy to use, such as eliminating the need to erase the personal identification number.
