Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic control device, and more particularly to an electronic control device that controls the opening and closing of hotel room doors, locker doors, rental car doors, and the like.

0-Skin W In recent years, in addition to using a key made of gold, a system has been proposed that uses a magnetic card or punch card to lock and unlock a door lock device. A keyless system 11 has been proposed that unlocks an electronic lock by inputting the same number as a pre-registered number using multiple switches without using the key.For example, Japanese Patent Publication No. 14910/1983 As shown, a system for unlocking a door using a card is known.Also, as shown in Japanese Patent Application Laid-open No. 56-105076 and Japanese Patent Publication No. 59-32632, a system using a plurality of switches in a predetermined manner is known. The solution #ta is obtained by operating in the order of
Electronic locks that generate time are known. However, in a lock control system that uses a key or card, there is a risk that the key or card may be stolen by someone else.
left behind or duplicated indoors or in another different location;
It is also troublesome as it requires careful handling. Keyless engine using M/number of key switches as opposed to 2J!・Resiste t1 has the power of anti-theft and crime prevention:) Every time the use and - change, the password must be changed to a registration number that cannot be identified by the previous user or others. When changing the registration number using the central control device installed at the front desk of the hotel, an online system must be established by electrically connecting the central control device at the front desk and the locking devices in each section. Must be. For this reason, there are problems such as requiring a large amount of expense in terms of equipment. In order to solve the above problems, the present invention provides a progressive 1+J
After registering a user code number by inputting a guest code number that can be accessed, one objective is to provide an electronic control device that generates an unlocking signal by inputting only the user code number. The electronic control device according to the present invention includes a guest code progressive circuit that generates a progressive signal to progressively advance the guest code number, and a guest code progressive circuit that stores the guest code number and generates the progressive signal. a guest code storage means which advances the code number to the next Guess 1 when the Guess 1 code is received;
A guest code comparison means for comparing the IFI No. and 3 and sending out a match (No. 3) when a match is reached, and a user code storage means for storing an arbitrary user code number inputted by a plurality of switches in response to a match signal. A user code comparison means that compares the user code number stored in the user code storage means with the numbers inputted by the plurality of switches and generates an unlocking signal when they match, and a lock activated by the unlocking signal. The guest code number is progressive by the progressive signal of the guest code progressive circuit, and a new guest code number is set in the guest code storage means. When the code numbers match, a match signal is output from the guest code comparison means. Based on this match signal, the user code storage means stores any number newly inputted by the plurality of switches as the user code number. When the number entered by operating the switch matches the user code number, the user code comparison means sends an unlocking signal to the lock control device.In the state where the user code number is registered, this A user code number is used to unlock the locking device. However, the guest code used to store this user code number can no longer be used. For this reason, the user cannot use the card with the guest code number written on it. Even if you lose it or someone else can read it, the lock device cannot be unlocked. Therefore, after checking in, you will not be able to unlock or enter the room unless you use your user code. Only after the progressive circuit generates the progressive signal can a new user code number be registered.On the practical side, an embodiment of the electronic control device according to the present invention applied to a hotel room room will be described. Figures 1 to 3 will be explained. First, as shown in Figure 1 (n), the door of each room has a
A keyboard 10 is attached which has a plurality of switches 11 on which numbers O to 9 are displayed, a check-in switch C, a checker 1- switch O, and a star 1-switch ST. The keyboard 10 is electrically connected to a control unit 12 composed of, for example, a one-chip microcomputer, as shown in FIG. 1(b). The control unit 12 has an input port to which a plurality of switches 11 and a guest code initialization switch 13 are connected. Moreover, the control unit 12 is. It has an output coupler -1- connected to each base of transistors 14, 15.1f3 as drivers. Each collector of the transistors 14, 15 and 16 is connected to a lock control device 18. each having an actuator 17, such as a solenoid or a motor. Connected to buzzer 19 and display 20. The emitters of transistors 14, 15 and 16 are all grounded. The buzzer 19 generates a sound to confirm the suppressed state when any of the plurality of switches 11 is suppressed. Further, the display device 20 is a light emitting diode that is energized when one of the numbers (guess 1 to code number C) matches. In addition, the control unit 1-12 has an unlock switch ((
[And a progressive switch 63 is provided. Further, the control unit 12 includes a guess l-code progressive circuit that generates a progressive signal to progressively advance the guest code number, and a guess code progressive circuit that stores the guess code number and receives the progressive signal (, Y
When the guest code storage means progressively advances to the next guest code number and the number inputted by the plurality of switches 11 matches the guess 1 to code number registered in this guest code storage means, a match signal is generated. It has a guest code comparison means. Furthermore, the control unit 12 includes a user code storage means for storing a user code 1 which is entered by the user with an arbitrary password by operating the plurality of switches 11, and a user code stored in the user code storage means. When the number entered in the number matches =, a match signal is generated and this -
It has a user-to-1 comparison means that sends the Atsushi signal to the lock control device 18 as an unlocking signal. When the control unit 12 is composed of a one-chip microcomputer as shown in FIG. 1(b), the control unit 12 is operated according to the operation sequence shown in FIG. 2. The coupon for the hotel you checked in is the room number, stay [l]
You will be given a card at the front desk with the number and guest code number printed on it. Therefore, the usage piece inputs the check-in switch 0 and start switch S 'I' of the keyboard 10 provided adjacent to the door of the designated room,
7M number of switches 11t! : Operate in the prescribed order,
The user inputs the same number as the Guess 1-Court number displayed on the handed card (step Sl). At this time, the buzzer 19 generates an operation 2f every time a plurality of switches 11 are depressed. Second, a large number of guest code numbers are stored in advance in the guest code storage [- stage] in the control unit 12.
These Guess 1-code numbers are determined by, for example, a random number table, and programmed so that they can be sequentially output in a predetermined order. The guest code number and its order are the same as the contents of the storage means of the card issuing machine provided in the front desk 1-. The guest code numbers stored in each guest code memory F1 are supplied to the guess I/coat comparison stage. 11 [In step S1, at the stage of inputting the guest code number, assuming that the user code number shi) according to an arbitrary PIN number is not registered in the user code storage means, in step S2, the user', -, 3Q N
:'i! ';' l, and step S 3
Step 6 Next, the guest code comparison means in the control unit 12 determines whether the number input in step S1 matches the number 1 to the code number. - When the error occurs, a - error signal is generated from the guest code comparison means, and a match is displayed as in step S4.
As a result, the user code storage means enters the write mode in which the user code can be stored. When the user code storage means is in the light mode, when an arbitrary number is input using the plurality of switches [1 in step S5, that number is stored in the user code storage means as the user code number (step S6). When the user code number is stored in the user code storage means, the lock control device 18 is activated by the M key signal (step S7) generated from the user code comparison r= stage.
The actuator 17 is operated at IpH. At the same time, the 1 indicator 20 is activated and the process returns to the start. In step S3, when the numbers input by the plurality of switches 11 do not match case 1-code number-j. The process advances to step S10, where it is compared with the next guest number. Here, it is determined whether the input number matches the next guest code predetermined using a random number table or the like. If they do not match, return to star 1~,
If they match, the contents stored in the guess 1-code storage means are advanced by the guess 1-code progressive circuit. Therefore, a new guest code number is switched in place of the previous guest code in the game code storage means (step 5ll). Therefore, the user code ejection that was used last time is deleted (step 512). On the other hand, after checking in, if the user locks the door, goes out, and re-enters the room, it is not necessary to input the guest code 1 number again, but only the registered user code number. That is, when a number is input using the current switch [1, this number is compared with the user code number at the registration end by the user code comparing means (step S
2) If step S9 matches, proceed to step S7 and output an unlock signal. Like F-! With respect to the F and II operation sequences, when there is no input from the plurality of switches 11 in step Sl, the following actions occur from step 320 onwards. For example, suppose that the room is unlocked by a manager such as a maid with a mask key and the person is entering the room. In this case, the Guess 1-code progressive circuit is mechanically unlocked by the mask key. Therefore, unlock switch 6■
is turned on, and a timer measures a predetermined time of, for example, 3 minutes from this switch on (step 521).
. The reason for setting the timer is to distinguish from cases where the Guess 1-Code progressive switch installed in the room is accidentally operated. The guest code progressive switch 63 is activated by the following operation within the predetermined time.
When is turned on (step 522), the guest code number is incremented (step S23). If the Guess I-'-do is unknown due to use over time, or if you want to initialize it, turn on the Guess 1 to code initial setting switches 13 without operating the guest code progressive switch (
In step S 2 =1), , sub-), the guest code number is returned to the progressive initial value (step 525). In addition, if you lose the guest code memory device given to you at the front desk when you first enter the room after check-in,
The user line requests reissuance of the next guest code number from Freon 1. If your lost card is handed over to someone else, Guess 1
- Even if someone else enters the room before you use it using your card number,
Since the user code number is stored based on the next progressive guest code number, the guest code number is automatically progressively changed to the next one. Therefore, after the user enters the room using the next reissued guest code note,
The lost previous Guess 1-code number has a usage rate of i+f. The progression of the guest 1-code number is performed in parallel by the guest code number storage means on the room side and the cart issuing machine on the front side. Next, FIG. 3 shows an example of the control unit 12 based on the above-described operation sequence. Switch 11 with 9 numbers is BCD conversion 1 for converting 2 communication signals.
11j 130 is connected to a guest code comparator 40 and a user code comparator (user code comparison means) 50. On the side of the guest 1 to code comparator 40, the address counter 42 and the guest code storage (guest code storage means) 4:3 are connected from the BCD conversion) 1:30 through the OR age 41. The output of the OR gate 41 is supplied to the buzzer 19 and the plurality of switches 1
An operating sound is generated from the buzzer 19 every time 1 is suppressed. In addition, the retrigger multivibrator 48 counts the time it takes to hold each input signal of the switch 11 at a constant value of 8 and ill (waveform shaping, and then the next switch) to lIi'IF. That is, after pressing the switch 11 in -2), it takes a certain period of time before pressing the next switch 11.
When the time elapses, the falling signal of the retrigger multivibrator 48 causes the one-shock 1-multivibrator 44
generates an output and resets the address counter /+2 through the OR gate 45. When the counter 46 counts a predetermined number of digits, such as 5 or 7 digits, it resets the address counter 42 and all other counters through an OR gate 45. Waveform shaped 'M! ．． The input signal from the number switch 11 is sent from the address counter 42 to the guest code memory/i3 as an address counter. I will. The guest code storage device 4:'S stores a large number of guest code numbers, for example, a combination of five numbers. These guess 1 to code numbers are progressively advanced by a guest code progressive circuit 60 via a counter 68. Further, the guest code storage device 43 is connected to the guess 1-code comparator 40. The guest code storage device 43 sends out the current guess 1 - court number and the guest code 1 to be advanced to the ratio 1bit'/+:'i40, and
Code comparison 'A: +4 0, when the current guest code number and the input numbers from the plurality of switches 11 match, output terminal 0. The output is sent to the counter 47. Guess l - the number of leading digits of the code number = match signal is the counter 4
When the count is 7, the address counter 42 is reset through O1<gate 49. In addition, in the guest code comparator 40, when the next guest code number to be progressively matched with the input number by the plurality of switches 11, an output is sent to the counter 68 from the output terminal 1r-02. When a signal is input to the guest code comparator 40 by the operation of multiple switches 11 by the user, the address counter 4
In response to the address signal No. 2, the guest code storage device 43 supplies the stored guest code number to the guest code comparator 40. For this reason. The guest code comparator 40 compares the number inputted by the plurality of switches 1 with the number stored in the guest code storage 43, and sends an output to the counter 47 every time the number reaches one S. This output is counted by the counter 47, and when all the digits of the guest code number match, the counter 47
A match signal is sent out from the display 20, and a match is displayed on the display 20. Further, the address counter 42 is reset to 1-. Here, if the user code number is stored in the user code storage device 51, the user code storage device 51 generates a high level output from the output terminal 0. Therefore, in the gate control circuit 70, the go1-circuit 71 is in a conductive state, and the output of the counter 117 is supplied to the set terminal of the R/S flip-flop 73 through the OR gate 74, and therefore the R/S flip-flop 73 is changed to the set state. When the R/S flip-flip tube 73 is in the set state, a high level signal is applied from the Q terminal to the gate circuit 52 and the W/R terminal of the user code storage 51, so when the gate circuit 52 is switched to the conductive state, At the same time, the user code storage 51 is switched to the RIE 1-mode. In this state, if an arbitrary number is set using the plurality of switches 11, that number will be displayed in the address counter 4.
The user code is stored in the user code storage 51 according to the address signal No. 2. When all numbers of predetermined digits are stored in the user code storage device 51, the output generated at the output terminal O is switched from high level to low level. At this point, Wangshoso 1
- The multivibrator 72 generates an output, the flip-flop 73 is reset, and the Q terminal output is switched to a low level. Therefore, the user code storage H 51 is switched to read mode. Goo 1 - circuit 52 is switched to a non-conducting state. Also, the output of the one-shot multivibrator 72 causes O r
<Input is input to the lock control device 18 through games 1 to 55.
'j- is selected and the lock control device 18 is activated. Therefore, the door can be unlocked. After that, the door can be unlocked simply by entering the user code number. At the same time, the display 20 is activated and the address counter 42 is reset. That is, an input number is given to the user code comparator 50 by actuation of the plurality of switches 11, and an address signal is inputted to the user code storage +41 5 1 through the address counter 42. Therefore, the user code number read from the user code storage 51 is given to the user code comparator 50 (17). The user code comparator 50 generates an output every time each digit matches, and this output is counted by the counter 53. When all the digits match, the output of the counter 53 is sent to the lock control device 18 through the OR gate 55 and unlocked. At this time, when counted by the counter 53, 0 1 <The address counter 42 is reset through the gate 54. When the lock control device 18 is activated, its output is displayed on the display 2.
The lock is set to 0 and the unlock display appears. In the embodiment of the present invention, the code progressive circuit 60 to Guess 1 operates an unlock switch 61 that is activated when the manager, such as a maid, unlocks the door using a mask key (mechanical or infrared remote control). Uzuro. That is, when the unlock switch 61 is turned on, the timer 62 is activated, and for example, the timer 62 is activated.
A timer output is given to the ΔND game 1-65 for a predetermined period of minutes. When the guest code progressive switch 63 is turned on within this predetermined time, the ΔN l) game 1-65 generates an output and becomes 0.

1'i+). Therefore, the guest code number in the guest code storage device 43 is automatically progressively advanced to the next predetermined number from 1 to 1. This is the same as when changing the storage number. Also,
The guest code number becomes progressive when the number input by the t9 number switch 11 matches the guest code number. This is also done by the output of a counter 6ε3 which counts the output occurring at the output 7-o2 of the guest code comparator 40. OR gate r'=
When 6 generates an output, the gold counter is reset. Guest code: Progressive circuit (:0 is provided with a guest code initial setting switch 13 that initializes the Guess 1 to code numbers. This Guess 1 to code initial setting switch] 3 is connected to the timer 62 as well as the HND gate 67. The output of the gate 67 is connected to the reset terminal ``fR'' of the guest code storage 43. If you turn on the guest code initial setting switches 1 and 3 during the predetermined time when the output is being generated, the /'I N I) gate will receive an output from 7 and 1.
- 1. The guess i-code number in the memory 43 is reset to the progressive initial value. Or < to game 1 (46 and △l"J D gate [; 7 output is OR game 1~,
Since it is supplied to the OR key 1 45 and the reset 1 terminal of the user code storage unit 51 through 80, 01ζ game hG ('i and ΔN]-1 game l-F:
With the output of , the counter 42 and the user code memory 51 are set to ljt. After the user code 1-. is recorded in the self-storage unit 51, the 'L-mine' code number is recorded. The user code comparator 50 described above compares the iterated user code number with the number input by the switch 11. In this user code comparator 50, the result of the comparison is ->9, and the matching signal when the result is found is sent to the lock control device 18 as an unlocking signal. In the lock control device 18, an actuator 17 such as an electromagnetic solenoid is actuated by this unlocking signal. As is clear from the structure and operation of 1U, the guest code number is 5'! -8, and then an unlock signal is output by inputting the user code number,
After a guest checks in, the system is such that even maids and other management staff cannot unlock the room using the guest code number like in the past. Therefore, when the customer is out,
The only way to enter the room on the management/8' side is to unlock it with a mask key, which provides protection against theft and crime against external intruders and front management/8. In this case, the administrator's N. Entry into the lock is performed using a master key. On the practical side, an example of implementing the present invention on a hotel door has been described, but it is also possible to implement the present invention on rental locker doors or rental car doors installed in public facilities such as golf courses. The electronic control device according to the present invention can only operate the lock control device by inputting the same user code number as the user code number arbitrarily registered by Sukawa. Since the lock control device can be activated, it has a high anti-theft effect. Also, since the lock control device can be managed offline, equipment costs can be reduced. Furthermore, a keyless entry system can be established for multiple uses. Therefore, you must carry the key with you even if you use it.
