Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a door unlocking system, and particularly to a door unlocking system suitable for application to an automatic door system of an apartment complex management system.

[Background of the invention II] Recently, automatic doors have become popular in communal housing units such as condominiums. This type of automatic door automatically or unmannedly prevents unauthorized entry by outsiders.
The door is locked during normal operation, and in order to unlock or open the door, the resident must enter a PIN number known only to the resident using the numeric keypad on the panel of the communal entrance machine, or use the reverse master key owned by the resident. use On the other hand, a visitor calls the dwelling unit he/she is visiting through the doorphone or intercom of the common entrance machine and has the door unlocked by remote control from the home controller in the dwelling unit.

By the way, in this type of system, if an outsider repeatedly operates the numeric keypad with an appropriate fl@, an OI message may be accidentally generated.
It may match the identification number and be unlocked.

Therefore, a predetermined time is set in advance as the door unlocking time, and if, for example, the correct password is not entered within this door unlocking time after pressing the numeric keypad for the first time, countermeasures such as issuing an alarm are taken. , preventing unauthorized entry by outsiders.

Conventionally, this door unlocking time is set to a predetermined value in PROM.
(Proaraiable Raad 0nly
Mallor V) as fixed data, and this value was used. However, depending on the usage status of the collective entrance, there are times when it is desired to change the door unlocking time. In this case, in the method of storing in PROM, this PRO
This was very inconvenient as M itself had to be replaced or the stored value had to be changed. On the other hand, there is a method in which a DIP switch or the like is provided for setting the door unlocking time and the time is set using this method, but since a DIP switch is newly provided, the cost increases.

[Object of the Invention] In view of the above-mentioned problems with the conventional system, an object of the present invention is to provide an automatic door system for an apartment complex management system that easily sets and unlocks the door unlocking time exclusively for the apartment entrance without increasing costs. The purpose of the present invention is to provide a door unlocking system that can be changed from time to time.

[Summary of the Invention] In order to achieve the above object, the door unlocking system of the present invention includes a PIN number setting switch, a numeric keypad, and a comparison between data input from the numeric keypad and setting data of the PIN number setting switch. If it matches, unlock the door 1111
11 circuits and a door unlocking clear time setting switch, and the password setting switch is used as the door unlocking time setting switch for a predetermined period of time when the door unlocking time setting switch is turned on.

That is, the door unlocking system of the present invention compares the data entered by a resident etc. by operating the numeric keypad at the collective entrance machine with the PIN data set in advance with the PIN number setting switch, and checks whether they match. This is a door unlocking system that sends a door unlocking signal to the door interface circuit to unlock the door, and after turning on the door unlocking time setting switch, the password setting switch is turned on for a predetermined period of time. It is used as a lock time setting switch, and the set value of the password setting switch is stored in a memory and used as the door unlock time timer value.

This makes it extremely easy to set or change the door unlock time.

Note that the password setting switch may also be used as a numeric keypad. That is, the setting of the identification number and the setting of the door unlocking time when the door unlocking time setting switch is turned on may be performed using the ten keys. Also,
The password setting switch may be a switch that performs the conventional function, and the setting of the door unlocking time ti when the door unlocking time setting switch is turned on may be performed using a numeric keypad.

[Description of Example 1 Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 shows a schematic configuration of a door unlocking system according to an embodiment of the present invention.

In the figure, 1 is a password setting switch, 2 is a door unlocking time setting switch, 3 is a control circuit that controls the overall operation, 4 is a RAM, and 5 is a ROM. In addition, 6 is the panel of Kyodo Genllll11, the numeric keypad provided on the side, 7
is a door interface (door T/F) that transmits a signal indicating door unlocking etc. issued from the control circuit to the door rMrf1 mechanism.

In the above configuration, when a resident etc. inputs the password It@ using the numeric keypad 6 of the communal entrance machine, the control circuit 3 inputs the input number and the password? Check the PIN number set by the setting switch, and if they match, open the door.
/Sends a door unlock signal to F7. This will unlock the door.

To set the door unlock time, use the door unlock time set switch 2.
This is done using the password setting switch 1. first,
When the door unlocking time setting switch 2 is turned on, the control circuit 3 detects the rising edge of the switch and stores the value of the password setting switch 1 in the RAMJ as the value of the door unlocking time for a predetermined period of time, for example, one minute from that point. Remember. That is, for one minute after turning on the door unlocking time set switch 2, the password setting switch 1 is used for setting the door unlocking time, and during this time, by setting the desired door unlocking darkness value, the door can be unlocked. Lock time can be easily set. After a predetermined period of time has elapsed, the password setting switch will again function as the original password setting switch.

When a person who knows the password, such as a resident, operates the numeric keypad 6 of the communal entrance machine, the control circuit 3 uses an internal timer to measure the elapsed time from the time the numeric keypad 6 was pressed. Then, this elapsed time is successively compared with the door unlocking time set in the RAM 4. If it is determined that the elapsed time has exceeded the door unlock time, press numeric keypad 6.
The system assumes that the person operating the password does not know the password, and takes necessary measures such as issuing a warning.

As described above, it is possible to reduce the possibility that a person who does not know the password enters without permission. [Effect of the Invention] As explained above, according to the present invention, the door unlocking system can be used to unlock the door. Time Sera (- Since the PIN code setting switch can be used as the door unlocking time setting switch for a predetermined period of time after the switch is turned on, it is extremely easy to set or change the door unlocking time of the collective entrance, and the door unlocking time This method has the effect of reducing costs compared to a method that requires a dip switch cap for setting.
