[Detailed description of the invention] [Industrial application field]

The present invention relates to an electric lock for an entrance door installed at a common entrance of an apartment complex, and relates to a system for unlocking the electric lock by inputting a set password or identification code.

[Conventional technology]

In an electric lock device where an electric lock is installed on the common entrance door of an apartment complex and is unlocked by entering a PIN number, the PIN code for unlocking the front door is, for example, a date set at the entrance. There are some that allow setting using a four-digit number or the like by operating a push switch or the like. Therefore, if it is desired to change the password, the change can be made by operating the dip switch or the like again. However, this PIN is a common PIN that is required for people entering and exiting this apartment complex to open the front door, and changing it is required for all residents of this apartment complex, even non-residents. It is necessary to ensure that the person authorized to enter and exit the facility memorizes the new PIN number. However, the more people involved, the more difficult it is to ensure thorough implementation, and due to these constraints, changes are often virtually impossible. Therefore, it does not affect the residents who are currently coming in and going out, and for example, the front door cannot be opened for someone who was a resident of this apartment complex in the past (who knew the PIN number) but who would not be allowed to come in and out at the moment. There was a need for an electric locking device that could take measures to prevent accidents.

[Problem to be solved by the invention]

Reference numeral 11 denotes an input unit for inputting data such as a password to be stored in the memory unit 8. Reference numeral 12 denotes a display section that displays data and the like input in response to operations on the input section 11. 13 measures the time with a clock section, and input section 1
A signal is output within the time range set by operation 1. 14 is a storage unit that stores programs for controlling the management unit B and the like. Next, the operation of the electric lock system according to the present invention will be explained. To open the door to the common entrance, first operate the numeric keypad on the input section 1 of the entrance section Δ and enter the specified PIN number, or use an ID card with a predetermined identification code magnetically recorded on it. Insert it into a card reader and read the data. These pin code data or identification code data signals are transmitted from the input section 1 to the control section 2, and then to the telephone of the management section B via a communication signal line installed between the entrance section A and the management section B, etc. It is transmitted to the telephone exchange 6 and inputted from the telephone exchange 6 to the determination section 9 via the control section 7. The determination unit 9 compares the signal based on the operation of the input unit 1 with the data of the personal identification number or identification code read from the memory unit 8 via the control unit 7, and outputs a determination signal when they match. This signal is applied to the unlocking signal generating section 10 via the control section 7, and the unlocking signal generating section 10 generates an unlocking signal for unlocking the electric lock based on this signal input. The unlocking signal is then transmitted to the entrance section A via the telephone exchange 7 and the call signal line, and is applied to the electric lock driving section 3 via the control section 2.
The electric lock drive section 3 drives the electric lock of the entrance door to unlock and open the door. If the signal from the input section 1 does not match any of the data read out from the memory section 8, based on the determination of the mismatch by the discriminating section 9, the mismatch stored in the storage section 14 etc. is sent via the control section 7. An alarm signal is read out and transmitted to the entrance A via the control unit 7 and the telephone exchange 6, and the display signal generation unit 4 via the control unit 2 indicates that the PIN is incorrect or the ID card is used. A display signal or an audio signal is generated to notify that the device is disabled. Then, the generated signal is applied to the display unit 5 via the control unit 2, and the display unit 5 displays the message in text on the screen or in voice from the speaker, such as ``The password is incorrect'' or ``This card is not valid.'' The data such as the password or identification code stored in the memory section 8 is written by the operation of the input section 11.In other words, the required operation of the input section 11 causes the device to perform the data writing operation. , and enter the numeric value of the PIN or identification code to be memorized while checking the digits displayed on the display unit 12. Also, set a PIN that is valid only for a specific period, i.e., , to allow workers to enter and exit the building for construction work inside the house while residents are absent, or to allow newspaper delivery people to come and go during a specific time range every day, etc., set a PIN code that is valid only during a specified time range. To set this password, etc., set the password stored in the memory section 8 as a number with a specific identification code "*", etc., such as r*511J, and enter this number etc. in the input section. 11, the data is written into the memory section 8. The time during which this password is valid is set by inputting date and time data into the data storage area of the memory section 8 such as r*511j by operating the input section 11. As a result, for example, a construction worker or the like can enter the password r*511 in the input section l.
When inputting J, etc., the determination unit 9 determines the r*511J
It is determined whether there is any corresponding data, and if the corresponding data is determined, the time/date/time data is further determined and a signal is output. Then, based on this discrimination signal, the electric lock of the entrance door is unlocked. In addition, when the previous resident moves and another resident moves into the unit, the input unit 11 is operated to erase unnecessary data such as passwords from the memory unit 8 and new data is written. Make me remember. By providing the memory section 8 with a capacity capable of storing data such as a plurality of passwords, it is possible to set passwords that are easy for each resident to remember.

【Effect of the invention】

As explained above, in the electric lock system according to the present invention, when the PIN number entered at the entrance etc. matches any of the multiple PIN numbers etc. set and stored in the storage device, the entrance door can be locked. The electric lock is unlocked. Therefore, it is possible to set an easy-to-remember password for each resident who moves in, so it is possible to avoid problems such as forgetting the password immediately after moving in and not being able to enter the home without bothering the manager or the like. Furthermore, since the data in the storage device can be rewritten by the necessary operations, it is an easy-to-use and highly secure electric lock system that can eliminate the problem of unauthorized entry by former residents who have moved.
