Abstract

PURPOSE:To make burglar prevention more effective by letting a progressive signal be used from a progressive cord comparator to a guest cord progressive circuit by means of remote actuation so as to let a new user cord number be set up, and thereby letting a releasing signal be issued to a lock control device based on said signal. CONSTITUTION:Electromagnetic waves including cord numbers are generated by means of a remote actuation device, and the output from a receiving means 14 allows a progressive cord comparator 24 to compare the aforesaid cord number with the cord number of a progressive memory means 23 so as to allow a progressive signal to be generated by a guest cord progressive circuit 60, when agreement is good in the aforesaid comparison for letting a new guest cord number be set up in a guest cord memory means 43. And when an input number by plural numbers of switches 11 is consistent with a new guest cord number, a consistent signal is outputted from a guest cord comparator 40 so that a given number to be newly inputted into an user cord memory means 51 is stored as an user cord number. After then, when a number inputted from the plural numbers of the switches 11 is consistent with the user cord number, a releasing signal is issued from the comparator 50 to a lock control device 15 so that the lock is released.

Description

[Detailed description of the invention]

The present invention relates to an electronic control device, and 1!1 is an electronic control device for controlling the opening and closing of hotel room doors, locker doors, rental car doors, etc. Regarding a control device. One of the tricks of the trade in recent years. For locking and unlocking the door lock device, in addition to using a metal key, systems have been proposed that use a magnetic card or a punch car. A keyless entry system has been proposed in which an electronic key or card is used to unlock an electronic lock by dialing the same number as a pre-recorded number using a plurality of switches. For example, as shown in Japanese Patent Publication No. 58-14910, a system for unlocking a door using a card is known. Further, as shown in Japanese Patent Application Laid-Open No. 56-105076 and Japanese Patent Publication No. 59-32632, electronic locks that generate an unlocking signal by operating a plurality of switches in a predetermined order are known. . However, with a lock control system that uses a key or card, there is a risk that the key or cart may be stolen by someone else.
There is a danger that items may be left behind or duplicated indoors or outdoors. Also, at hotels, etc., it can be a hassle to leave your keys and cart at the front desk when you go out. On the other hand, in a keyless computer system that uses multiple key switches, each time the user changes, the PIN must be changed to a registration number that cannot be identified by the previous user or by others for the purpose of preventing theft and crime. Bana17. No, 3. When changing the registration number using the central control device installed at the front desk of the hotel, the central control device of Freon 1- is electrically connected to the lock device of each room and the online system 1.
1 must be confirmed\γ. For this reason, there are problems such as requiring a large amount of expense in terms of equipment. In order to solve the above-mentioned problems, the present invention provides a progressive guess! - Need number - After inputting the user code number and recording the user code number, the objective is to provide an electronic control device that generates an unlock signal by inputting only the user code number. Key, 3L (without sewing) 1T σ - child actor The electronic control device according to the present invention includes a remote control device that generates electromagnetic waves from 21 to N, and a receiver 1 that receives the electromagnetic waves generated by the remote control device. a progressive code storage means, and a progressive code comparison means for comparing the received signal (M signal i) by the receiving means with a code signal stored in the progressive code storage means and generating a match signal when they match. and progressive comparison 1;
Comparison r: A guest court progressive means that generates a progressive signal to progressively advance the guest code number based on the coincidence signal of the stage, and stores the GUESS 1 to NEET number -) and when the progressive signal is received, the next CAS 1-code. Guess l-rJ − that progresses to the number
1- A memory stage, a guest code comparison means for comparing the number inputted by a plurality of switches with a guest code number stored in the guest code storage means, and sending out a match signal when they match, and a guest code comparison means. Means Atsushi (+i
A user code storage unit that stores arbitrary user code numbers inputted by a plurality of switches according to a number of switches [, 1 and 2 stored in the user code storage means] and a plurality of switches. Compare the number entered in
It has a user code comparison means that generates an unlocking signal when a match occurs, and a long control device that is activated by the unlocking signal. Activated by the IL tube section activating the remote control device. Electromagnetic waves containing code signals are generated. Upon receiving the output of the receiving means that received this electromagnetic wave, the 10-stage progressive needle comparison compares the needles 1 to (It So) stored in the progressive code storage means. When both match, the F-stage progressive code comparison Give the match signal to the guest code progressive means to generate a progressive signal in the guest code progressive means.The guest code number . The number is set. When the input number by the -l number switch matches the new guest code number, a matching signal is output from the comparison means to the guest code 1. This -rM iCi number causes the user code to be stored. f = stage is an arbitrary If newly inputted by partitioning multiple switches
i So is stored as the user code number. Thereafter, when the number entered by IQing a plurality of switches matches the above-mentioned user neat comparison 1 stage, unlocking (1t 7i-) is sent to the lock control device. In the case S where the user code number C) is 3't, M,
This user code number is used for the N lock of the lock control device. However, the code used to store this username number can no longer be used. Therefore, even if the card on which the use case 1 to need number 5 is written is lost or read by another person, the lock device cannot be unlocked by another person. Therefore, after checking in, you will not be able to unlock or enter the room unless you use your user code number. In this case, a new user court number can be registered only after the progressive means generates a progressive signal. An embodiment of the electric control device according to the present invention applied to a door in a hotel near the Fudan moat will be described with reference to FIGS. 1 to 4. First, FIG. 1 (1)) As shown in the figure, the door of each room has a plurality of switches 11 with numbers O to 9 displayed on them, a check-in switch C, a check-out switch O, a star 1-switch ST, and an infrared light receiving sensor ( 0 is attached to a keyboard 1 having a receiving means) 14. As shown in FIG. The control unit 1-12 has an input port to which a plurality of switches 11, a guest code initial setting switch 13, a user code clear switch 63, and a light receiving sensor 14 are connected, and also serves as a power source for each of these components. It has an output capacitor connected to each base of a battery or a live transistor (not shown).If a transistor is used, each collector has an actuator such as a solenoid or a motor for lock control. Device 1
It is connected to a 5° buzzer 16 and a display 17, and each emitter is grounded. Buzzer 16 has multiple switches 1
1 is suppressed, a sound is generated to confirm the suppressed state. Further, the 1 indicator 17 is a light emitting diode that is activated when the guest code number matches -. The control unit 12 includes a timer means, a progressive code storage means, and a progressive code that compares the signal received by the light receiving sensor of the reception means with a code signal stored in the progressive code storage means and generates a matching signal when they match. When the comparing means and the progressive code comparing means memorize guest code 1 (guest code progressive means generating a progressive signal for progressively increasing the number, and guess 1 to code number -) based on the matching signal, and receive the progressive signal. The next guest code storage means compares the number inputted by a plurality of switches with the number stored in the guess 1~code storage means, and sends out a match signal when they match. A code comparison means and a user 2 which stores an arbitrary user code number which is inputted by a plurality of switches according to a coincidence signal of a code ratio of 1, α', and
The user code stored in the user code storage means is inputted using multiple switches, and the unlock word is generated when -sy is pressed. User: J-1 ~ has comparison means. Lock control device 15
is activated by the unlock signal of the user code comparison means. As shown in FIG. 1 (I), the control unit 12 is a one-chip microcomputer with a 49. If so, the control unit 12 is operated according to the operating sequence shown in FIG. If you are a hotel user who has checked in, please enter your room number and stay I.
Insert the card with the number and guest code number printed on it.
・It will be handed over. In step S1, the user inputs the switch S'F to the check-in switch C and the star 1 of the keyboard 1-10 provided on the door of the designated part hall l or adjacent to this door, and 11 in the predetermined order and enter the guest code number (same as the guest code number displayed on the cart you were given). At this time, the buzzer 16 generates an operating sound every time the plurality of switches 11 are pressed. Here, a large number of guest code numbers are stored in advance in the guest code storage stage in the control unit [2].
These guest code numbers are determined by a random number table and programmed so that they can be output in a predetermined Ill'i order. The contents of the note tα in the note tα means of the rejected card issuing machine are the same.The guest code S3 stored in the guest code storage means is supplied to the code comparison means for the guest code S3. At the stage of inputting the code number to 1, if it is assumed that the user code number is an arbitrary PIN number and has not been registered, it is determined in step S2 that the user code is not registered, and the process proceeds to the next step S3. The first code comparison means determines whether or not the number inputted by the plurality of switches 11 in step S1 matches the guest code 1 output. If they match, a match (rt) is generated from the guest code comparison stage, and the display is displayed as shown in step S.

[A match is displayed at 7. As a result, the user code storage means stores i by input.
+'l Powerful light mode. When the user code storage means is in a memorizable state, when the user enters a random number using the plurality of switches 11 in step S5, that number is stored in the user code storage means as a user code number (step S6). When the user code number is stored in the user code storage means, the user code comparison means generates an N (lock signal) (step S7). This unlock signal activates the actuator of the lock control device Ml15 to unlock the door. At this time as well, the display 17
Then, an unlock display is made (step S8), and the operation sequence returns to the start. In step S3? When the number input by the U number switch 11 does not match the guest court number, step S
The process advances to step SIO from :3, where the guest code comparing means compares the guest code number with the next guest code number. Here, it is determined whether the input number is -H with the next guest number determined by a random number table or the like. If they do not match, the process advances to step S20, and if they match, the guest code I-
The memory contents of the notation α step are progressive. For this reason, the new guest court numbers from 1 to code number S'T will be replaced by the previous guest court numbers! - Switched by the code storage means (step 511). At this time, the user code number used in the previous line is displayed (step 512). On the other hand, when the user locks the door after checking in, goes out, and re-enters the room, there is no need to input the guest court number again, and the user inputs the registered user court number using a plurality of switches 11. The input number is compared with the registered user coat number by the user code comparison means (step S2), and if they match, the process proceeds from step S to step S7, and an unlocking signal is output. If there is no input from the plurality of switches 11 in step S], the operation sequence is step S2. It works as follows below. For example, after a user checks out a room, the hotel manager operates the remote control device 20 as a master key. The remote control device 20 uses infrared 1
Has a 1s band light emitter. It can also be unlocked by emitting infrared radiation containing a specific code number. FIG. 4 schematically shows a block diagram of the remote control device 20. This remote control device 20 includes a control circuit l whose central control unit fi (CPU) is a one-chip microcomputer.
and the memory '/+'fr (R
OM) 2, a switch 4 and a battery 5, also connected to the input port I of the control circuit 1 via a trigger circuit N; 3, and a transistor with a base connected to the output ports -1 to 01 of the control circuit 1 6, a light emitting diode 7 for infrared emission connected between the collector of the transistor 6 and the ground, an output port 02 of the control circuit 1, and a memory type 2.
It has a light emitting diode 8 for display connected between. To explain the operation in this case, the star l-switch ST on the locked i.a. keyboard 10 is suppressed by the administrator and turned on. For this reason,
The 9471st stage of the control unit 12 activates the light receiving sensor 11 for a certain period of time and sets it to a receiving state (step S21).The reason for setting the certain period of time is to reduce power consumption and to This is to prevent malfunctions in the circuit due to unnecessary operations on the switch installed in the circuit. When the switch 4 of the remote control exterior '1120 is operated to suppress the light receiving sensor 14 for a certain period of time and the light emitting diode 7 for emitting infrared rays emits light, an infrared signal containing a predetermined code number is generated. The light emitting signal is detected by the light receiving sensor 14 (step S22), and the converted electric power signal is input to the control unit 1-L2. The progressive code comparison means in the control unit 12 compares the input electric signal with the code signal stored in advance in the progressive code storage means and determines whether they match (step 5).
23). - If defeated, the progressive code comparison means sends the matching signal as an unlocking signal to the lock control device 15 (step S 2 /l). At the same time, turn on I' by star 1-switch ST
When the user code clear switch 63 is turned on by the following operation within a certain period of time (step 525), the user code comparator is cleared (step 826), and then the guest court number used by the previous user is cleared. is automatically advanced to the next code number (step 527). In step S22, when the signal from the remote control device 20 is not received within a certain period of time when the timer F step is activated, or in step S25, the user code clear switch 63 is turned on within a certain period of time when the timer step is activated. If not, proceed to step 828. If the guest code number is unknown due to use over time, or if you want to initialize the progressive code number, turn on the code initialization switch 13 for guest 1 in step S20 (
step 828). Thereby, the process advances to step S29, and the guest code number is returned to the progressive initial value. At this time, the timer means is cleared. Next, the process proceeds to step S30, and when the timer means counts a predetermined time, step S31
Then proceed to turn off the light receiving sensor 14. Step 828
If the guest court initial setting switch 13 is not turned on in step S30, the process advances to step S30. If the tie 11 is not up in step S30, step S2
Return to 0. In addition, if the user loses the card with the guest number court number given at front desk 1- when entering the room for the first time after check-in, the user will request a +1j card with the next guest code number displayed at the front desk. do. If the lost cart is handed over to another person and another person enters the room before the user using the guest number, the guest code storage means will change the guest code number to the next number. progress to. Therefore, the user will be reissued the next guest code number -)
After entering the city using the , the lost city guest court number will no longer be available. The progression of the guest code number is 1
This is done in parallel by the guest code storage means on the room side and the card issuing machine on the front side. Next, FIG. 3 shows an example of the control unit 12 based on the above operation sequence. A plurality of switches 11 is connected to the B C for converting the 2 communication signals [1 from the converter 30 to the Guess! code comparator (guest code comparison stage) 40 and the user code comparator (user code comparison stage B) 50]. There is. On the side of the guest code 1 to the comparator 40, the address counter 2 and the guest code storage device (guest code storage means) 43 are connected from the BCD converter 3Q via the OR codes 1 to 41. The output of the OI gate 41 is supplied to the buzzer 16,
An operating sound is generated from the buzzer 16 for each pressure 111 of the plurality of switches 11. In addition, in the first-rega multivibrator 48, the waveform is shaped to hold each of the switches 11 for a certain period of time, and the time until the ninth switch [1] is pressed is counted. That is, when a certain period of time has elapsed until one switch 11 is pressed, the one-shot multivibrator 4 is activated by the falling signal of the retrigger multivibrator 48.
4 generates an output to reset address counter 42 through OR gate 45. Counter 46 is 5 N7
Alternatively, when a predetermined number of digits such as 7 digits are counted, the address counter 42jF; and other counters are reset through the OR gate 45. The waveform-shaped input signal of the ty number switch 11 is sent from the address counter 42 to the guest code storage 43 as an address signal. In the guest code storage device 43, a number of guest code numbers are stored, for example, in five numbers. These guest code numbers are advanced by a guest code advancement circuit 60 as guest code advancement means via a counter 68. Further, the guest code storage device 43 is connected to the aforementioned guest court. 4; 3 sends the current guest code memory device 2 1 number and the number of the guest code memory 2 to the guest code comparator 40 at the same time, and this guest code comparator 40 compares the current guest code number and When the input numbers from the plurality of switches 11 match, an output is sent from the output terminal 01 to the counter 47. When the counter 47 counts the number of leading digits of the guest code number, the address counter 42 is reset through the OR gate 49. Further, in the guest code comparison 8t40, when the next guest code number to be progressively matched with the input number by the plurality of switches 11, an output is sent from the output terminal 02 to the counter 68. When a signal is input to the guest card comparator 40 by the user's operation of the plurality of switches 11, the address counter 4
In response to the address signal No. 2, the guest code storage device 43 supplies the stored guest code to the Guess 1 to code comparators 40. For this reason, the guest code comparator 40 compares the numbers inputted by the plurality of switches 11 with the guest code memory 4.
3, and each time the numbers match, they are counted by the counter 47. When all the digits of the guest code number and number match, the counter 47 sends out a match signal and the display 17 shows A match will be displayed. Further, the address counter 42 is reset. Here, in the user code memory Hg 5 1 Knee+J
If the need number n is stored, the user code storage unit 5
1 generates a high level output from the output terminal O□. Therefore, in the gate control circuit 70, the gate circuit 71 is in a conductive state, and the output of the counter 47 is output from the OR gate 1-.
7 4 'r through r</S flip-flop 7
As a result, the R/S flip-flop 7:3 is switched to the set state. R
/ When the S flip-flop 73 is in the set state, a high-level signal at the Q terminal r or IEI is applied to the gate circuit 52 and the W/R terminal of the user code storage 51, so the goo1-circuit 52 becomes conductive. At the same time, the user memory 51 is switched to the light mode. In this state, when a number is set using the plurality of switches 11, that number is stored in the user code storage 51 by the address signal of the address counter 42. When all the predetermined digits are stored in the user code storage 51, the output generated at the output terminal o8 is switched from high level to low level. At this point, one-shot multivibrator 72 generates an output, flip-flop 73 is reset, and the output at the Q terminal is switched to a low level. Therefore. User code storage 51 is switched to read mode, and gate circuit 52 is switched to a non-conducting state. Also. OR by the output of one-shot multivibrator 72
Lock control through gate 75'! When the input is entered into the device 15, the lock control device 15 is activated. Therefore, the door can be unlocked.After that, the door can be unlocked simply by inputting the user code number. At the same time, the display 17 is activated and the address counter 42 is reset. That is, the input number is given to the user code comparator 50 by the activation of the plurality of switches 11. The user code is stored through the address counter 42 if:
An address signal is input to +51. Therefore, the user code number read from the user code storage 'A'/151 is provided to the user code comparator 50. The user code comparator 50 generates an output every time each digit matches, and this output is counted by the counter 53. When all digits match, the output of the counter 53 is output to the OR gate 55.
The signal is sent to the lock control device 18 through the lock control device 18 to be unlocked. At this time, when the counter 53 counts, the address counter 42 is reset through the OR gate 54. When the lock control device 15 is activated, its output is displayed!
rt on 7. The lock will be unlocked. By using the infrared remote control device 20 in the guest court as a master key, the room that the user has checked out can be unlocked and a management side such as a maid can enter the room. Further, based on this N lock operation, it is possible to progress from Guess 1 to Code No. 1. That is, light reception, sensor 14 is star 1
- due to suppression of switch ST. A certain period of time set by a timer (timer means) 21 (
(e.g., 3 minutes) and is energized. After that, infrared remote control′! When the A position 20 is operated to emit light, a light emitting signal including a predetermined code number is received by the light receiving sensor 14 on the door side. After the signal received by the light receiving sensor 14 is amplified by the amplifier 22. The signal is sent to the comparator (progressive code comparison means) 24 and the lead knee 1 to the detection circuit 25. Lead need detection circuit 2
5 has a function of detecting the read code arranged at the beginning of the signal given from the amplifier 22 and activating the memory 8:+ (one stage of progressive code memory) 23. On the other hand, the signal output from the amplifier 22 is compared to H: +2
4, it is compared with a predetermined code signal previously stored in the memory 2:'I. When these signals match, the comparator 24 generates a match signal, which is supplied to the lock control device 15 through the OR gate 55 to unlock it. At the same time, the match signal from comparator 24 is sent to ΔAND gate 67 in guest code progressive circuit 60. At this time,
When the user code clear switch 63 is turned on, the AN
An output is generated at the D gate 67 and supplied to the progressive terminal (+) of the Guess 1 code storage 43 through the OR gate 66. Therefore, the guest code of the guest i-code storage device 43 is
1. The number is reset to the initial progressive value. OR'7' h 66 and H A N D goo 1-67
The OI? output is supplied to the OR gate 45 and the reset terminal of the user code storage 51 via the OR gate 80. , G1-E; 6 and A N +), the address counter 42 and the user code storage 5 are reset depending on the output of the gate 67. This is similar to the case where the storage number is changed by changing the address by progressively increasing the address by the counter, as described above. Similarly, when the number input by the guest code number switch 11 matches the next guest code number stored in the guest code storage device 43, the output generated at the output terminal 02 of the code comparator 4o to the guess 1 is counted. This is also done by the output of counter G8. When 66 generates an output to Or<G1, all counters are reset. Further, the code progressive circuit 60 to the guest 1 is provided with a guest code initialization switch 13 for initializing the guest code number. This guest code initial setting switch 13 is connected to the input terminal of an AND gate 65 together with a timer 62 . The output of the AND gate 65 is connected to the reset terminal r< of the guest code storage 1343. Therefore, an output is generated from the guest court AND gate 65 during the predetermined time period during which the timer 62 is generating an output, and an output is generated from the OR gate 65.
9, the guess 1 to code numbers of the guest code storage device 43 are reset to progressive initial values. Furthermore, if the guest code 1 initial setting switch 13 is turned on while the comparator 24 is generating an output, the A N
An output is generated from the D gate 68 and the OR game h 6 9
The guest code storage 43 is cleared to the initial value through the process. Further, this guest court progressive circuit 60 is provided with an IW62 switch 61 which is similarly operated by the administrator to unlock using a metal mask key. That is, when the unlock switch 61 is turned on, the timer 62 is activated, and a timer output is given to the AND gate (55) for a predetermined period of, for example, 3 minutes.
When turned on, the A N D gate (5 4) generates an output which is supplied to the progressive terminal (+) of the guest coat memory 'A:'r/1.'3 through the gate 66. , the same as the case of the initial setting switch 13 to the guest code 1. In the above embodiment, an example was explained in which infrared rays were used as the electromagnetic waves emitted from the remote control exterior 'lvi20, but in addition to infrared rays, radio waves It is also possible to use local electromagnetic waves, such as sound waves and ultraviolet rays.Also, in 1-1, on the actual flow side, an example was shown in which the present invention is applied to a hotel door. It will be understood that the present invention can also be implemented on a rental locker door or a door for a rental car.
Since the lock control device can only be operated by changing the coat and inputting the same user code number as the user code entered in 31B, the anti-theft effect is high. Furthermore, since the lock control device can be managed off-line, equipment costs can be reduced. Furthermore, since a keyless entry system can be established for a large number of users, users are freed from the inconvenience of having to carry a key. Since the user code numbers of , and can be input and stored, there is no risk that the guest code numbers will be read by others. That is, after one guest has checked in, even the manager, such as the five maids, cannot unlock the room using the guest code number as in the past. While the customer is out, the manager has no choice but to unlock and enter the room by operating the remote control device that serves as the master key, which is effective in preventing theft, intrusion, and crime prevention against external intruders and the Freon manager. It will be done. Further, the electronic control device according to the present invention uses a remote control device that generates an optical signal. It is convenient because the lock control device can be operated from a position away from the door, and it is also highly effective in preventing theft.
