Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a microcomputer locker having a microprocessor and a keypad. It relates to microcomputer lockers that can control unlocking of locker doors that do not have additional control # devices by inputting a number.

[Prior Art] A conventional microcomputer locker is equipped with a numeric keypad switch for each door, and a control device including a microprocessor for each fold. A key switch is provided on each prisoner, and after operating this key switch, the wlIri number is set. It is normal for a manager to be present when setting the password, and the key switch is usually operated by the manager. Although it is possible to configure a single control unit including a microprocessor, it is necessary to wire many lead wires from the six doors to the control device.

[Problems to be Solved by the Invention] If this conventional microcomputer locker consists of a single control unit, it will require many lead wires from the six doors to the W control device, and there is a risk of malfunction due to noise. At the same time, the number of man-hours required for wiring becomes large.

In addition, it requires the same number of numeric keypad switches as doors, so it has the disadvantage of increasing costs. In the case where the operating section and the control circuit are provided in the l1 section, the storage capacity of the locker is reduced and the amount of i in the door section is increased, causing problems in operability. In addition, operating the numeric keypad switch provided at a low position was cumbersome. Furthermore, if lockers with similar shapes are added, the user has the disadvantage that it takes time and effort to identify the desired locker.

The present invention was created in view of the prior art,
A single operation unit can be used to unlock and control the doors of additional lockers that do not have a control unit, and the storage space is large.
The purpose of this invention is to provide a microcomputer locker that can be configured at low cost.

[Means for Solving the Problems] The microcomputer locker of the present invention includes a numeric keypad switch for inputting serial numbers and a password, a plurality of doors assigned a group of numbers that can be unlocked by a solenoid, A control device that generates a signal to unlock the door having the serial number and password inputted from the numeric keypad switch, and a terminal that supplies a signal to control the locking and unlocking of the door to which the serial number of another group is assigned. are integrally constructed, and by inputting the serial number and password of the door of the other group using the numeric keypad switch, it is possible to lock and unlock the locker of the other group. According to a preferred embodiment of the present invention, the solenoid provided on the door is energized only for a predetermined period of time by inputting a serial number and a password using a numeric keypad switch.

[Function] In addition to a group of serial numbers integrally configured to control multiple prisoners, the microcomputer locker is also equipped with a control device that controls the locking and unlocking of other locker doors that do not have a control H position. provided. When the serial number and password are input using the numeric keypad switch, a signal for unlocking the corresponding door is supplied. By preparing the terminals in advance, it becomes possible to control the locker without having many control devices. Closing of the locker is possible even after the solenoid provided in the six doors is de-energized, and the user of the locker can close the door at will.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. 1 to 6.

FIG. 1 is a perspective view of an embodiment of the invention. In the same figure, reference number 1 indicates a microcomputer locker according to the present invention. This microcomputer locker 1 includes a single control device 3 equipped with a plurality of s2 and a numeric keypad switch. A solenoid is provided inside the $2, and when the solenoid is energized, the solenoid 12 can be opened.Reference numbers 20 and 30 in the figure indicate additional lockers, and these lockers 2
0.30 is equipped with a solenoid for unlocking 11121.31. The microcomputer locker and the additional locker 20.30 are electrically connected to each other by a connector (not shown) on the back side. In this case, the serial numbers of the microcomputer locker I are assigned, for example, 1 to 22, and the doors of the locker 20 are assigned numbers 23 to 46. Similarly, the doors of lockers 30 can be assigned numbers 47-700.

However, it is also possible to change the serial number assigned to each locker by changing the connection of the connector.

12 is an enlarged front view of the control device 3, in which the operation keys 4 are provided at the top. The operation key 4 is constituted by a key switch whose contacts are closed or opened by key operation.The normal operation key 4 is operated by an administrator as will be described later. The control device 3 is provided with a numeric keypad switch 5 for inputting a serial number and a password, and display devices 7 to 11 such as light emitting diodes for displaying operating states.

FIG. 3 is a side view of the control device 3 shown in FIG. 2. Normally, the numeric keypad switch 5 is arranged on the front surface which is inclined to improve operability.

Further, the operation key 4 is arranged on a surface that is erected from the inclined part. This control device 3 can be configured in various shapes taking design and other considerations into consideration.

FIG. 4 is a block circuit diagram of a control circuit for a microcomputer locker according to the present invention. In the figure, reference number 12 is a microprocessor, and various controls are performed by this microprocessor 12.

The contact outputs of the operation keys 4 and the outputs of the numeric keypad switches 5 are supplied to the microprocessor 12 . A RAMI 4 and a ROM 15 are connected to the microprocessor 12. A control program for the microprocessor 12 is stored in the ROM 15. The RAM 14 is used as a work area for a control program for the microprocessor 12 and for storing a password. Reference number 17 is a display element such as a light emitting diode, and although it is shown as a single block in the figure, a plurality of display elements are provided to confirm the operation. Further, reference number 58 indicates a solenoid provided on each door of the microcomputer locker 1, and a driver circuit (not shown) or the like is provided between the solenoid and the microprocessor 12.

The microprocessor 12 shown in FIG. 4 is further shown connected to a solenoid 21 and a solenoid 31 via a connector 23 and a connector 33. Soleno, Ido 21
1 generally shows those provided on the door of the added locker 20, and solenoids 31 collectively show those provided on the door of the added locker 30. Although not shown in the drawings, it is possible to connect even more additional lockers.

Since the RAM area for storing password numbers and serial numbers is extremely small, many lockers can be easily added by providing a plurality of connectors.

Next, the action of the microcomputer locker of the present invention is shown in FIGS. 6 and 6.
This will be explained with reference to the flowchart shown in the figure.

FIG. 6 is an operation flow diagram when setting a password. When the operation key 4 is operated by the administrator in step 5100, a serial number can be input in step 5lot. This serial number is input, for example, by the manager of a safe deposit box at a bank or a rental locker at a golf course. ! The s number is entered by inputting, for example, a three-digit numerical value, and finally, by pressing the # key of the numeric keypad switch 5, the input of the serial number is completed. When it is confirmed in step 5102 that the # key has been pressed, step 51
At step 03, it is checked whether the operation key 4 has been operated again. Generally, re-operating the operation key 4 corresponds to an operation such as removing the key. After operation key 4 is operated again, a serial number can be input in step 5104. Here, the user of the door enters a serial number, and when it is confirmed in step 5105 that the # key has been pressed, the serial number input by the administrator and the serial number input by the user are matched in step 5106. It is confirmed whether the If it is determined in step 3106 that the serial number input by the administrator and the serial number input by the user do not match, control proceeds to step 510.
You will be prompted to return to step 4 and re-enter. If it is determined in step 9106 that the serial number is correct, step 5IO
At step 7, the password can be entered. Here, a password having a predetermined number of digits is input, and when it is confirmed in step 8108 that the # key has been pressed, the password setting is completed. Although not shown in FIG. 5, the display device 7 such as a light emitting diode lights up when the operation key 4 is operated, and the display devices 78 to 11 such as light emitting diodes light up each time the password is input. The order of operations and the display on the display device such as a light emitting diode can be configured in various combinations, and the above is just an example.

Next, the operation of unlocking using a password will be explained with reference to FIG. FIG. 6 is an operation flow diagram at the time of unlocking. In step 5200, a serial number is input using the numeric keypad switch 5, and when it is confirmed in step 5201 that the # key has been pressed, a password can be input in step 5202. When it is confirmed in step 5203 that the # key has been pressed at the end of the PIN, it is determined in step 5204 whether the PIN corresponds to the serial number input in step 5200.
If it is determined that the 8 number and the password match, the door is unlocked in step 5205. When unlocking, a solenoid provided on the door is energized for a certain period of time. This time is counted by a timer, step 520
When the timer counts up in step 6, the energization is released and the lock becomes available in step 5207. Locker doors can only be opened when the solenoid is energized, and cannot be opened after the solenoid is de-energized; however, if the timer counts up or times out while the door is opening, the solenoid will open. Even if the power is de-energized, there is no problem because the door can be manually locked at will.Even when the door is unlocked, the display devices 7 to 11 such as light emitting diodes are used to indicate each operation. The condition is clearly indicated. In addition, if the user forgets the password or to manage the locker, the administrator can unlock the locker by operating the operation key or inputting the secret number.

[Effects of the Invention] As described above, according to the present invention, it is possible to perform unlocking control of the door of an additional locker that does not have a control unit using a single operation unit, and the storage space is wide and the cost is low. This has the effect of providing a microcomputer locker that can be configured as follows.
