Description

Description: TECHNICAL FIELD The present invention relates to an electric lock unlocking device for unlocking an electric lock using a card. [Background Art] Conventionally, in this type of electric lock unlocking device, a dedicated card (for example, a magnetic card) is separately prepared for each product, and the unlocking operation is performed using a different card for each product. . As described above, if a dedicated card is created for each product, the number of cards that tend to increase in number, such as bank cards (cash cards) or credit cards, which are currently generally issued, is further increased. Therefore, there is a problem that it is inconvenient for the user to carry, and it is difficult to recognize which card is used for which purpose, which makes the user very inconvenient. [Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to release an electric lock which can be unlocked with a general card used for other purposes. A locking device is provided. [Disclosure of the Invention] (Constitution) The present invention provides a card reading unit for reading the identification code of a general card such as a bank card in which an identification code for specifying the card is written, and an identification code in which the identification code is stored in advance. An identification code comparing unit that outputs a signal for unlocking the electric lock when the memory matches the identification code of the card read by the card reading unit with the data stored in the comparison data memory and agrees with each other; And an identification code registration switch operated when registering a new card as a card for unlocking an electric lock, and an identification code read by a card reading section when the identification code registration switch is operated. An identification code registration unit for registering the identification code of a new card in the identification code memory. It is that to be able to unlock the. (Embodiment 1) FIG. 1 is a view showing one embodiment of the present invention. In this embodiment, an electric lock is unlocked by using a card in which an identification code for specifying the card is written. The unlocking device for an electric lock according to the present embodiment includes a card reading unit 1 that reads the identification code of a card, an identification code memory 3 in which the identification code is stored in advance, and a card reading unit 1 that reads the card. An identification code comparison unit 2 that outputs a signal for unlocking the electric lock when the identification code matches the data stored in the identification code memory 3 and matches, and unlocks the new card with the electric lock. Code registration switch 4 operated when registering as a card for use, and an identification code for registering the identification code read by the card reading unit 1 in the identification code memory 3 when the identification code registration switch 4 is operated. It consists of a registration unit 5. The identification code memory 3
In the prior art, a ROM memory was used so that stored data could not be rewritten. In the present embodiment, data can be rewritten as a RAM memory. Hereinafter, the operation will be described. First, the operation of registering the identification code of a new card in which the identification code for specifying the card is written in the identification code memory 3 will be described. First, the identification code registration switch 4 is turned on.
Then, by inserting the card into a card insertion slot or the like of the card reader 1, the card reader 1 reads the identification code written on the card. The identification code read by the card reading unit 1 is registered, that is, written in the identification code memory 3 by the registration unit 5. Thereafter, when the identification code registration switch 4 is turned off, the identification code read by the card reading unit 1 is input to the identification code comparison unit 2,
By comparing with the identification code stored in the identification code comparison unit 3, it is determined whether the card inserted into the card reading unit 1 to unlock the electric lock is a registered card, and the registered card is registered. If it is a card, it outputs a signal to unlock the electric lock. As described above, by providing the identification code registration switch 4 and the identification code registration unit 5 and enabling the data stored in the identification code memory 3 to be rewritten, there is no need to create a dedicated card for each product, and a general card can be used. For example, if an identification code such as a bank card is registered in the identification code memory 3, a bank card and a card for unlocking an electric lock can be used in common, and therefore the number of cards can be reduced. Usability is improved for the user. If you want to delete the identification code of the card registered as described above, for example, you may want to use another card as a card for unlocking the electric lock, etc. The data stored in the memory 3 can be erased. First, a power switch (not shown) for supplying power to the unlocking device body of the electric lock is turned off. In this state, the identification code registration switch 4 is turned on, and then the power switch is turned on. The data stored in the identification code memory 3 can be erased. Since the registration data in the identification code memory 3 can be easily erased in this manner, it is possible to quickly respond to a case where the card is lost. A card having a horizontal redundancy check code (LRC code) at a predetermined byte as a card (for example, a bank card
When the second byte has a horizontal redundancy check code), the identification code of the card can be securely registered. In other words, when the identification code registration switch is operated and a new card is registered as an unlocking card,
When the value obtained by performing an exclusive OR operation on the data up to one byte before the predetermined byte and the value of the horizontal redundancy check code match, the identification code read by the card reading unit 1 is registered in the identification code memory 3. By providing the identification code registration unit 5 with a function of performing identification, the identification code registration unit 5 can determine whether or not the identification code read from the card by the card reading unit 1 is incorrect. The identification code can be registered in the identification code memory 3 only when the error occurs.
That is, the card user can register the magnetic card identification code in the identification code memory using the registration switch on site. At this time, as a means to prevent the magnetic card from being registered in the identification code memory even though it cannot be read correctly due to bad reading of the magnetic card, etc., it is determined whether the magnetic card was read correctly at the time of reading That is, a horizontal redundancy check code is used. If the magnetic card registered in the identification code memory is lost, all data registered in the identification code memory can be deleted. Normally, input means such as a numeric keypad and a display and display means are required to delete a magnetic card, but by using a combination of a registration switch and a power switch,
With a simple configuration based on the method of deleting data, the data deleting means of the identification code memory can be realized. Furthermore, if the following display unit is provided so that the operating state of the electric lock unlocking device can be accurately determined, the operation can be performed more reliably. As the display unit, a red light emitting diode and a green light emitting diode are used. When the identification code registration switch 4 is turned on, both light emitting diodes are turned on, and when a registerable card is inserted, a green light emitting diode is used. Is blinked for 5 seconds, and when a card that cannot be registered is inserted, the red light-emitting diode is blinked for 5 seconds, so that it is possible to accurately determine whether the card can be registered or not.
Further, when the data of the identification code memory 3 is erased, when the power switch of the unlocking device main body is turned on, the identification code registration switch 4 is turned on, so that both the red and green light emitting diodes are turned on. It can be seen that the registration data in the identification code memory 3 has been deleted. Also, when inserting the already registered card and unlocking the electric lock, the green light emitting diode is turned on for 2 seconds at the output of the identification code comparison unit 2 generated when it is determined that the card is correct, and the card is correctly If not, the red light emitting diode may be turned on for 2 seconds. (Embodiment 2) FIG. 2 is a view showing another embodiment of the present invention. In this embodiment, the security of the card is checked by comparing the identification code of the card and the password input by the ten keys 6. It is intended to improve the above safety. Therefore, the unlocking device for an electric lock according to the present embodiment includes a numeric keypad 6 for inputting a security code for identifying a user of the card, and the security code in advance at the subsequent stage of the circuit described in the first embodiment. When the stored identification code memory 8 and the identification code coincide with the data of the identification code memory 3 in the identification code comparison unit 2, the data stored in the identification code memory 8 and the numeric keypad 6 are input. A password code comparison unit 7 that outputs a signal for unlocking the electric lock when the input code is compared with the input code and operates when registering a new card as a card for unlocking the electric lock. Security code registration switch
And a password code registering section 9 for registering a password entered by the ten keys 6 in the password code memory 8 when the password code register switch 11 is operated.
In the above-described embodiment, the registration data stored in the identification code memory 3 is erased by the registration switch 4 and the power switch. However, in this embodiment, the numeric keypad 6 and the identification code memory 3 are deleted. PIN code memory 8
Are connected via erase switches 12 and 13, respectively, the erase switches 12 and 13 are closed, and a special erase code is entered with the ten keys 6 so that the registered data can be erased. An output unit for unlocking the electric lock and controlling the operation of the display unit is provided as an output of the personal identification code comparison unit 7.
10 are provided. Hereinafter, the operation will be described. First, a case of registering a new card will be described. First, the identification code of the card is registered in the identification code memory 3 as described in the first embodiment. Next, the personal identification code registration switch 11 is turned on, and an appropriate personal identification code to be attached to the card is input from the numeric keypad 6 using the numeric keypad 6. The input code entered by the ten keys 6 is used as a secret code registration unit 9.
Is written in the password code memory 8. Thus, the electric lock can be unlocked with the card and the numeric keypad 6. Now, when the card is inserted into the card reading section 1 and the identification code is correct, that is, when the card is correct, the personal identification code is input by the ten keys 6 next. For a long time after the card is inserted (for example,
If the security code is not entered with the numeric keypad 6 during 20 seconds), it is not preferable from the viewpoint of security for crime prevention.
If there is no operation of the numeric keypad 6 within 20 seconds, the input of the numeric keypad 6 is not accepted by the password code comparison unit 7.
As described above, the period for receiving the input from the ten keys 6 is
By blinking the green light emitting diode of the first embodiment described above for 20 seconds, the input possible period is indicated to the user with the ten keys 6. The input code input by the numeric keypad 6 (code immediately after input by the numeric keypad and input data that has not been recognized as a security code) is compared with certain data registered in the security code memory 8 by the security code comparison unit 7. Is done. When the personal identification code (the data determined as the personal identification code) matches, the output unit 10 unlocks the electric lock at the output of the personal identification code comparing unit 7. Also,
If the passwords do not match, the output unit 10 flashes the red light emitting diode for 5 seconds in accordance with the output of the password comparison unit 7 to notify the user that the password is incorrect. The registered data in the identification code memory 13 can be erased by turning on the erase switch 13 and inputting “9” to all digits using the numeric keypad 6, for example. Can respond to. [Effect of the Invention] As described above, the present invention provides a card reading unit that reads the identification code of a general card such as a bank card in which the identification code for specifying the card is written, and an identification that stores the identification code in advance. An identification code comparison for outputting a signal for unlocking an electric lock when a code memory and an identification code of a card read by the card reading unit are compared with data stored in the identification code memory and they match. Unit, an identification code registration switch operated when registering a new card as a card for unlocking an electric lock, and an identification code read by a card reading unit when the identification code registration switch is operated. It has an ID code registration unit to register in the ID code memory, so when an electric lock unlocking device is installed in a building, for example, the user can register on site. There is an advantage that the magnetic card identification data can be freely registered in the identification memory unit by using the switch, and the magnetic card already possessed by the user, for example, an employee card or a bank card can be used as it is, and in particular, the electric lock is unlocked. It is economical because there is no need to prepare a dedicated card for the device and there are few magnetic cards to carry, and it is not necessary to record an identification code for each product in advance at the factory shipment, making it easy to manufacture products. is there. In other words, by turning on the identification code registration switch, the data stored in the identification code memory can be rewritten by the identification code registration unit, so that it is not necessary to create a dedicated card for each product, and a general card can be used. For example, if an identification code of a bank card or the like is registered in the identification code memory, a bank card and a card for unlocking an electric lock can be used in common, so that the number of cards can be reduced, and Since the number of sheets is reduced and the trouble of identifying which card is the unlocking card of the electric lock is reduced, there is an effect that the usability is improved for the user. In addition, even if the product is manufactured, it is not necessary to create an identification code memory in which an identification code is made different for each product, so that it is easy to manufacture.
