Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door opening/closing control device, and more particularly to a device for controlling the opening/closing of a door such as a safe that should only be openable by a specific person.

Door opening/closing control devices in conventional safes are generally mechanical, and by setting the dial to a predetermined combination of rotation i1i,', direction, and amount of rotation, I/A can be opened and closed. As long as you know the four dial settings, you can open and close I/A anywhere in the world, so there is a risk of misuse, and furthermore, once set, these dials cannot be changed.

The present invention has been made in consideration of the problems with the conventional type described above, and includes two keylet numbers, namely a first PIN number and a second PIN number string, and the first PIN number is input manually. By making it possible to open and close 1.A only when the three combinations of the time required to input the second PIN and the time required to input the second PIN match, it becomes more difficult for a third party other than a specific person to open and close I.A. In addition to making it possible to change the PIN number and time period as necessary, even if the PIN number and time d] are leaked to a third party, the third party's misuse is avoided as much as possible. The purpose of the present invention is to provide a door opening/closing control device that can control the door opening/closing. In order to achieve this objective, the present invention includes a first memory in which a first password is set, a second memory in which a second password is set, and a memory corresponding to the first password. a third memory in which a permissible period of time from when the first key is pressed until when a second key corresponding to the second password is pressed; a door opening/closing mechanism; and a first password. The door opening/closing mechanism determines that the number and the first key manual power and the second password and the second key manual power match and that the period of time is within an allowable range set in the third memory. and a determination unit that drives the determination unit.

The present invention will be described in detail below using the F1 side surface.

FIG. 1 is a block diagram showing the configuration of a door opening/closing control device according to an embodiment of the present invention. The apparatus shown in FIG. 1 includes a central control unit (CPU) 1, a memory only (ROM) 2, which stores each processing block. Random access memory (R
AM) 31 Clock 41 Mode switch 5 for switching between normal operation mode and preset mode for password, etc., power supply section 6
The main body 8 is equipped with a battery 7, a keyboard 9, a display section 1o, and an opening/closing mechanism section 11 connected to the main body 8.

As shown in FIG. 2, in the RAM a, there is a first memory area where the first pin code SC2 is set, a second storage area where the second pin code SC2 is set, and a lower limit of the time width. (Set time A) and upper limit (Set time B) are set, a third memory region, a first key human power buffer that temporarily stores the first key human power KII and the second key human power KI2, respectively; There is a second key human power buffer, as well as a first key human power KZI and then a second key human power KT.
It has various areas such as a counter that counts clock data until it reaches 2. Further, this RAM is backed up by a parallel circuit 7 so that the stored contents will not be destroyed even when the power supply 6 is cut off. Note that the above-mentioned PIN number SC'l can be stored by using an erasable blockable read-only memory (EPROM) instead of the RAM.

The SC2 and the set times A and B may be stored, and in this case, the battery 7 is not required.

The keyboard 9 includes numeric keys of clear keys C10 to C9, a password, and a setting key used to indicate that input using the numeric keys is a password.

The display unit 1O normally displays the contents of the clock 4, that is, the time. The person who opens and closes the door can look at this clock 4 and adjust the time range. The display unit 10 can also display an alarm in the event of an abnormality, such as when the one-hour width of the password does not match.

The door opening/closing mechanism section 11 can use a known mechanism such as one that automatically opens and closes the door using pneumatic force, electric force, etc., or one that simply locks and unlocks the door.

Next, the operation of the 1.A opening/closing control device shown in FIG. 1 will be explained with reference to the flowchart shown in FIG. In addition.

Setting the password and time can be done using a well-known method, so the explanation will be omitted.

An example of key operations when operating this device is as follows.

23 Setting 56 Setting Following the above operations, the apparatus of FIG. 1 operates as hJT'''.

First, when numerical data is entered manually from the keyboard ゛9,
This numerical data is sequentially stored in the 1 key manual buffer, and when the setting key F is further pressed, a counter is started. Next, it is determined whether the first key manual KII stored in the first key manual buffer and the first password SCI set in the first memory match.

If the first key manual input KII and the first password SCI do not match, error processing such as generation of an alarm is performed after the counter is cleared. In addition, when the first key KII and the first password SCI match, wait for the second key KII to be entered manually by pressing the number keys and the setting key F, and then press the second key KII. If there is a key KI2, the counter is stopped [1-]. Next, the second key human power KI2
and the second password - QSC2, and the time span counted by the counter, that is, the time from the first setting key press F to the second setting key press [] is the setting time A and the setting time. It is determined whether it is within the range between B and B. , -1-^1 If both decisions are YES, open the door, clear the counter, and complete the series!・A Finish the opening/closing control operation. Both or any of the above judgments are N
In the case of O, the error counter is cleared and error processing is performed to not issue an alarm.

As described above, according to the present invention, many combinations of two passwords and a time limit are possible, making it extremely difficult for a third party to misuse them. In addition, since it is electronic, the user can set the PIN number and time period at will, so there is less chance that the PIN number will be known to a third party compared to a case where the dial is set from the beginning. It can be changed even if it is known to a third party, making it highly secure against misuse.
