Abstract

By realizing a lock lock that can be unlocked at least in contact without lock, the key device practically makes non-normal duplication possible.

When the operation button 21 of the key device 10 is operated, the key device 10 outputs a call code from the light emitting portion 12.

Accepting this call code, the lock control device 11 outputs a random 99 response codes and only one response code unique to this lock lock device.

The location of the unique code is determined by a random number.

Therefore, it is not easy to know from the outside which is the unique code.

When the unique code is outputted, the key device 10 receives this code, generates a recognition code S, and outputs it.

Receiving this identification code S, the lock control device 11 unlocks the lock of the door 1, if the identification code is correct.

If the recognition code is incorrect or there is no response, the host computer 15 is notified.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock lock device and a response code recording device for use in the lock lock device. More specifically, the lock lock device includes a lock body for physically closing a door and a key device for opening the lock in a non-contact manner. It relates to a related device.

In the conventional lock locking device, it is common to insert a key into the keyhole of the lock main body and to physically open the lock in a state where both are in contact with each other.

Some of them are called electronic keys, which are made by drilling a hole representing a few bits of code into a card-shaped key or by embedding a magnet, but they can be used to adjust the position of the opening or the position of the magnet by inserting a card into the corresponding keyhole. If it is detected and recognized as a regular key, the lock is opened by driving an electromagnet or motor.

In this case, since card duplication is easy, a secret is secured by inputting a large number of digits into a panel with a door.

On the other hand, the lock-locking device which can operate a lock-opening by a non-contact is the present state that the use used for the door of an automobile is limited.

This is because, if there is any possibility of false operation by noise, the reliability as the lock locking device cannot be maintained at all, and the whole body does not become the body as the lock locking device.

In the case where the lock opening operation can be performed in a non-contact manner, a configuration may be considered in which a predetermined code is output by a key device through radio waves, ultrasonic waves, or the like, and the lock is opened if the receiver on the lock body receives the appropriate code.

However, in the configuration of sending a code for unlocking a lock (hereinafter referred to as unlocking) from the key device, it is necessary to assign a unique code to each key device, and since such a code is usually recorded in a PROM or the like, the key When a device is obtained, there is a problem that it is easy to interpret the code, and the reliability thereof becomes poor.

Moreover, by adopting a configuration that enables contact release of funds in a non-contact manner, the code necessary for unlocking is transmitted from the key device to the external space, so that the interpretation of the unlocking code becomes easier.

For this reason, in the unlocking device of the type in which the code is sent from the key device side to the lock main body, it is difficult to prevent illegal copying of the key device (so-called key production).

Therefore, in the lock lock device handled by an unspecified number of doors, such as a hotel door, it was common to replace the lock body and the key device every predetermined period in consideration of the possibility of illegal copying of the correct key. Had brought waste.

The lock lock device of the present invention solves such a problem, and aims at realizing a lock lock device that can be unlocked in a non-contact manner, but practically impossible to interpret or duplicate codes, and adopts the following configuration.

The lock lock apparatus of the present invention, as illustrated in the block diagram of FIG. 1, has a lock body M1 for physically closing a door, and at least an instruction means M2 for instructing an unlocking operation. A lock lock device having a key for unlocking M1 in a non-contact manner, the lock device being provided in the key device M3 and outputting a call code in accordance with an unlocking instruction by the indicating means M2. And response code output means M5 for outputting a plurality of response codes including a code defined as a code unique to the key device M3 which is combined with the lock main body M1 in advance when the call code is received; Is installed in the key device M3, and receives the output of the plurality of response codes and generates a code according to a predetermined or predetermined procedure when the key device M3 recognizes a code corresponding to a unique response code. Identification code output means (M6) for outputting the identification code and, when receiving the identification code, and comprising an unlocking means (M7), and that the lock body (M1) to the unlocked state to the base.

Here, each code exchanged with the key device M3 can take the configuration of being output as an optical signal.

It is suitable as a lock lock because it can be strong against noise and can provide directivity by sending and receiving by an optical signal.

By dealing with such a lock locking device, the invention of the response code recording device has been made.

The response code recording apparatus records a unique response code or a code corresponding to the code in the pair with respect to the pair of key devices M3 and the response code output means M5 of the lock lock body M1. The summary is provided with the recording means (N).

In the lock locking device of the present invention configured as described above, unlocking of the lock main body M1 is realized by the exchange between the key device M3 and the lock main body M1.

Sending and receiving will be described below.

When the unlocking operation is instructed by the instruction means M2 provided in the key device M3, the code output means M2 provided in the key device M3 outputs the call code.

Upon receiving this call code, the response code output means M5 outputs a plurality of response codes including a code defined as a unique code to the key device M3, which is to be combined with the lock body M1 in advance.

The output plurality of response codes are provided in the key device M3 and received by the recognition code output means M6.

Recognition code output means M6, when recognizing the code corresponding to the response code unique to the key device M3, outputs a recognition code generated according to a predetermined or predetermined procedure.

This identification code is received by the unlocking means M7.

Upon receiving the identification code, the unlocking means M7 sets the lock main body M1 that has physically closed the door to the unlocked state.

On the other hand, in the response code recording device of the inventor who handles the lock lock device, the record means (N) provides a pair of locks (M3) and response code output means (M5) of the lock lock device. Record a unique response code or a code corresponding to this response code.

EXAMPLE

In order to further clarify the constitution of the present invention described above, preferred embodiments of the present invention will be described below.

2 is a perspective view showing an example of the configuration of the lock locking device as an embodiment, and FIG. 3 is a block diagram showing the configuration of the lock main body and the key device.

In the present embodiment, the lock main body is buried in the door 1 of the hotel, the door lock drive mechanism 7 for inserting and removing the door lock 3 in the recess 5 of the wall by the small motor 2, The key device 10 and the lock control device 11 which drives the door lock drive mechanism 7 directly by optical communication are comprised.

On the surface of the door 1 at the portion where the lock control device 11 is buried, two openings are provided, and the light emitting part 12 and the light receiving part for optical communication attached to the casing of the lock control device 11 are provided in the opening. (13) comes up.

The lock control apparatus 11 corresponds to the response code output means and the unlocking means.

In addition, drive power is supplied to these door lock drive mechanism 7 and the lock control device 11 from the power supply cable which is not shown in figure.

These lock control devices 11 and the like are provided in each door 1 of the hotel, and all the lock control devices 11 are connected to the host computer 15 so as to be able to communicate with each other via the communication cable 14. It is.

The door 1 is also provided with a handle 17 for opening the door 1, and the handle 17 is rotated downward in a state where the door latch 3 is separated from the recess 5. The latch drive mechanism 19 allows the latch 20 to come out of the wall recess and open the door 1.

As shown in FIG. 2, the key device 10 is a square-shaped square stick-shaped member, and an operation button 21 is provided on one side, and the room number of the corresponding hotel is joined to the same side. have.

Although not shown in FIG. 2, a light emitting portion 23 and a light receiving portion 25 for performing optical communication are provided at the tip (see FIG. 3).

The light emitting part 12 of the lock control apparatus 11 and the light emitting part 23 of the key device 10 are comprised using the LED which transmits infrared light, The light receiving part 13 and the light receiving part 25 are It is constructed using a port diode that is sensitive to infrared light.

The internal structure of the lock control apparatus 11 and the key apparatus 10 is demonstrated.

As shown in FIG. 3, the lock control device 11 is a one-chip microprocessor (hereinafter referred to as MPU) 31, which has a built-in ROM storing a control program and a working RAM, and has an input / output port. The device is provided with an EEPROM 33 for storing a unique response code.

On the other hand, the key device 10 is composed of the MPU 41 and the EEPROM 43 similarly to the lock control device 11.

The MPU 31 and the MPU 41 can drive the light emitting unit 12 and the light emitting unit 23 directly through the output port to output a phase-modulated signal.

In addition, the input ports can be sensed to read signals output from each other. The same response code is simultaneously recorded in the EEPROMs 33 and 43 of the lock control device 11 and the key device 10 by the host computer 15, but the recording method will be described later.

The MPU 41 of the key device 10 uses the operation of the operation button 21 as an interrupt signal source. When the operation button 21 is operated, the operation button interrupt routine shown in FIG. Run

The MPU 41 reads the signal from the light receiving unit 25, controls the light emitting unit 23 to realize communication with the lock control device 11.

On the other hand, the MPU 31 of the lock control device 11 reads the signal from the light receiving unit 13 to control the light emitting unit 12 to communicate with the key device 10.

The MPU 31 executes the response code processing routine shown in FIG. 5 normally.

The MPU 31 may treat the signal from the light receiving section 13 as an interrupt signal, and if the interrupt mask is released, the MPU 31 executes the interrupt processing routine shown in FIG.

Since the processing shown in each drawing is performed while referring to the codes to be exchanged with each other, the reference drawings will be changed in order in the following, but for convenience of understanding, 400 steps are shown for each step shown in the flowchart of FIG. Numerically, each step shown in the flowchart of FIG. 5 is represented by 500 numbers, and each step shown in the flowchart of FIG. 6 is represented by 600 numbers.

A person using a guest room of the hotel, with the key device 10, arrives in front of the door 1 and pushes the operation button 21 toward the light emitting part 23 and the light receiving part 25 toward the door 1.

In response to the operation of the operation button 21, the MPU 41 of the key device 10 starts the interrupt process shown in FIG. 4, and first performs a process of outputting the call code C (step S 400). ).

Subsequently, a signal is input from the light receiving unit 25 (step S410), and it is determined that there is no signal input within a predetermined time period (step S420), and the signal is released until [RTN] ends and the interrupt routine is completed. The process of input (step S410) and the determination of whether or not the header is detected (step S430) are repeated.

The MPU 31 of the lock control device 11 on the door 1 side always executes the response code processing routine shown in FIG. 5 and constantly monitors the input of the signal to the light receiving unit 13 (step S). 500).

Therefore, when the call code C is output from the key device 10, this is detected (step S505), and a random number of integers between 1 and 100 is generated to generate a variable (x). ) Is executed (step S510).

In addition, in order to initialize the variable (n), a value (1) is substituted (step S 515), and a process of setting the value 0 to the flag F is performed (step S 520).

Next, a judgment is made as to whether or not the variable x into which the random number is substituted is equal to the value of the variable n (step S530).

Since the variable n is sequentially increased from the initial value 1 as described later, it is considered that the variable n eventually becomes the same as the variable x.

If the values of the variables (x) and (n) are not equal, random integers ranging from the value (0) to the power of 2 to 2 are generated as dummy data, which is converted into the variable R. Substitutive processing is performed (step S540).

Since randomly one of the 20 powers of 2 is randomly selected, the probability that the value is equal to the unique code of this lock lock previously stored in the EEPROM 33 is low, but the probability of matching If it is present, this is checked (step S545). If it does not match, a header H is attached to this variable R, and a response code is used to drive and output the light emitting unit 12 (step). S 550).

Thereafter, the variable n is incremented by the value 1 (step S 555), and it is judged whether or not the variable n exceeds the value 100 (step S 560). The process below step S530 is repeated until the value 100 is exceeded.

While the dummy data R is outputted as a response code several times, the value of the variable N becomes larger gradually and there is a timing at which the variable X becomes the same.

At this time, the process moves to step S570, attaches a header, and is inherent to the combination of the lock control device 11 and the key device 10 stored in the EEPROM 33 of the lock control device 11 in advance. The response code (hereinafter referred to as unique code) (D) is driven to output the light emitting unit 12 by outputting it.

After outputting the unique code D, the value 1 is set in the flag F (step S 575), the variable n is incremented by the value (1) (step S 555), and the variable ( The process from step S530 described above is repeated until n) exceeds the value 100.

Therefore, by repeating these processes, 100 response codes provided at the position where the unique code D is randomized are outputted.

At the same time as setting the value 1 in the flag F, the MPU 31 enables the signal input from the light receiving section 13 to be accepted as an interrupt signal.

In this state, when any signal is input from the key device 10, the signal input interrupt processing routine shown in FIG. 6 is started. This processing will be described later.

Thus, while the lock control apparatus 11 performs the process which receives the call code from the key device 10, and outputs a response code, the key device 10 senses the light receiving part 25, and reads a signal ( See also FIG. 4, step S 410. When the signal is read and the header portion is detected (step S430), the processing for reading the response code subsequent to the header is performed (step S440).

When the response code is read, it is next judged whether or not this code matches the unique code stored in it (step S 450). If the header is not detected (step S430) or if the read code does not match its own code, the process is repeated from the signal input (step S410).

Further, in step S450 of the present embodiment, it is directly determined whether the two match or not, but it is also possible to judge whether the two have a predetermined correspondence relationship.

Of the response codes sent out by the lock control device 11 over 100 times, if any code matches the unique code stored in the PROM 43 of the key device 10 (step S 450), the key device 10 Next, a process of generating the recognition code S is performed (step S460).

Various methods are considered in the generation of the recognition code.

The code predetermined may be sufficient, or the code generated based on the response code received from the lock control apparatus 11 may be sufficient.

As the latter technique, for example, a response code received using a predefined function is converted into a recognition code, and the response code is used to specify a number of digits such as n to recognize a predetermined range of values from here. It is possible to consider using a code, converting using a predetermined number of response codes as a constant for conversion, and the like.

The recognition code thus generated is output to the outside by the light emitting section 23 (step S470).

After that, the process returns to step S410 and the processing from the signal input is repeated, but when the signal from the lock control device 11 is not input over a predetermined time, it is not long before, at step S240. The judgment of [NO] becomes [RTN], and the routine ends.

When the recognition code is output from the key device 10, normally, the interruption by the signal input to the light receiving unit 13 is permitted (FIG. 5, step S575). The signal input interrupt processing routine shown in FIG. 6 is activated. do.

When this process is activated, a process of inputting a series of codes is first performed (step S 600), and it is judged whether or not the input code can be correctly recognized as a code (step S 610). This is because noise, which does not look like a code, may also be input.

If it is not code, it exits to [RTN] and terminates this routine.

If it is recognized that the input signal is a code, it is next judged whether or not the flag F is the value (1) (step S620).

If the interrupt input is allowed, the normal flag F will be set to the value (1), but the check is made to ensure more certainty.

Even if the flag F is not the value 1, if the recognition code is being accepted, it is assumed that there is a possibility that something is wrong, and the host computer 15 is connected to the host computer 15 via the communication cable 14. A process of notifying this is performed (step S625), and the routine is immediately exited to [RTN] to end this routine.

On the other hand, if the flag F is the value (1), it is subsequently judged whether or not the input code is correct as the recognition code (step S630). If the flag F is incorrect, the host computer 15 is notified (step S625). If it is correct, the motor 2 of the door lock drive mechanism 7 will be driven, and the door 1 will be unlocked (step S640).

Thereafter, the flag F is reset to the value (0) (step S650), and the routine ends.

If the flag F is reset to the value 0, the interrupt start request is masked and the signal input interrupt processing routine (Fig. 6) cannot be started.

In the signal input interrupt processing routine explained above, steps S 530 to S 560 of the response code processing routine shown in FIG. 5 are repeatedly executed, and the intrinsic value is determined for each lock locking device which is the key device 10 and the lock control device 11. Execution is possible immediately after outputting the code and setting the value (1) in the flag (F).

Therefore, when the response code processing routine shown in FIG. 5 has missed the repetitive processing by the condition determination (N> 100) in step S560, if the correct recognition code is output from the key device 10 by then, The flag F is reset to the value 0 (FIG. 6, step S650). On the other hand, if any code is not output from the key device 10 within a predetermined time, or if an incorrect code is output, the flag F is kept as the value (1).

Therefore, the value of the flag F is determined (step S580), and if the flag F is the value 1, the host computer 15 is notified that something abnormality has occurred (step S585). If the flag F is not the value (1), the process exits to [END] as it is and ends the processing.

Fig. 7 shows the exchange of codes between the key device 10 and the lock control device 11 described above.

As shown in the figure, when the operation button 21 of the key device 10 is operated, a call code is output from the light emitting unit 12 of the key device 10.

Accepting this call code, the lock control device 11 outputs a random code of 99 random codes and only one unique code unique to this lock lock device as a response code.

The position of the unique code with respect to the random code is determined by the random number and is different for each operation of the operation button 21.

Therefore, even if you monitor the code that both send and receive from the outside, it is not easy to find out which code is unique.

In addition, if the unique code itself is the same every time, even if the position is changed, it can be detected. Therefore, only multiple digits of a predetermined range of two powers of 20 are valid, and a value outside the range of the digits is changed every time. It is also appropriate.

When the unique code is outputted, the key device 10 receives the code, generates a recognition code S, and outputs it.

Receiving this identification code S, the lock control device 11 unlocks the lock of the door 1, if the identification code is a correct code.

If the identification code is wrong or there is no response, the host computer 15 is notified. However, in the case of the door 1 of the hotel, the user tries to open a room other than his own room by mistake. There may be cases of mistake, illegal intrusion by use of illegally duplicated key devices, and the like.

Thus, the host computer 15 issues a warning and instructs a response such as dispatch of a hotelman or security guard.

In addition, when a recurring error code is sent to the same door 1, an alarm is output immediately and, for example, the opening and closing of the elevator door is prohibited on the floor, and the guards can remove the floor from the floor. It is also possible to respond temporarily to reaching it.

In addition, if the room is an empty room, the response is to lock the door 1 by inverting the door 1 by instructing the host computer 15 to unlock the lock and infiltrating it. It is possible.

As described above, according to the lock locking device of the present embodiment, the door 1 can be unlocked in a non-contact manner, so that the user can easily handle the lock and the key device 10 and the lock control device 11 will be unlocked. By exchanging codes and confirming that they are a regular combination, the lock of the door 1 is unlocked, so that an advantage of high reliability is obtained.

In particular, in the lock locking device of the present embodiment, since the code to be transmitted and received is defined as a numerical value of two powers of two, it is impossible in time to simply unlock all the combinations by testing them. Since the reception is being confirmed, it is practically impossible to duplicate the key device 10.

The key code 10 and the lock control device 11 of the present embodiment store the codes unique to the lock lock device in the EEPROM 33 and the EEPROM 43.

Thus, by rewriting this code, you can easily change the code needed to unlock it.

Next, a configuration for updating and recording the contents of the EEPROM 33 and the EEPROM 43 will be described.

FIG. 8 is a block diagram showing the internal structure of the host computer 15 in a simplified manner and at the same time transferring data to and from the key device 10. As shown in FIG.

As shown in the drawing, the host computer 15 is provided with a well-known CPU 101, a ROM 102, a RAM 103, and an input / output port 105, and the input / output port 105 is provided for optical communication. The light receiving portion 113 and the light emitting portion 112 are connected.

The light receiving portion 113 and the light emitting portion 112 are the same as the light receiving portion 13 and the light emitting portion 12 of the lock control device 11.

Therefore, as shown in the drawing, when the key device 10 is disposed at a position opposite to the light receiving portion 113 and the light emitting portion 112, optical communication is performed between the key device 10 and the host computer 15. It is possible.

The communication from the key device 10 to the host computer 15 is, for example, by continuously pressing the operation button 21 for a predetermined time or pressing the reset button 45 through the pinhole as shown in FIG. If you do, you can configure it to start.

Here, the key device 10 starts the code initialization processing routine shown in FIG. 9 when the operation button 21 is kept pressed for a predetermined time or more.

When starting this routine, the key device 10 informs the host computer 15 of which key device 10 communicates, and the call code and recognition code stored in the EEPROM 43 up to that time. Is output to the host computer 15 (FIG. 9, S700).

In addition, in the case of generating by a recognition code | role and a predetermined algorithm, even if the code | cord | chord corresponding to a unique code is substituted for recognition code, there is no problem.

Originally, the calling code is all that is required.

The key device 10 outputs these codes and then performs a process of inputting a signal from the host computer 15 (step S710).

The key device 10 repeats the signal input process until the new code is received from the host computer 15 (steps 710 and 720).

Subsequently, when a new code is received from the host computer 15, it writes to the EEPROM 43 as a new unique code for identifying the key device 10 (step S730), thereby terminating this routine.

In addition, when the key device 10 is configured to output the recognition code stored in advance when the unique codes match, it is possible to receive not only a new unique code but also a new recognition code.

On the other hand, the host computer 15 reads the signal from the key device 10 and inputs a call code and a recognition code (Fig. 10, step S 750).

Subsequently, the host computer 15 refers to the table stored in the ROM 102 and performs a process of determining a new unique code between the key device 10 and the lock control device 11 (step S760).

This table stores correspondence between room numbers of all rooms of the hotel and the unique code of the lock lock device, and refers to the table so that the unique codes do not overlap.

The host computer 15 outputs the determined new unique code to the outside by controlling the light emitting unit 112 (step S770).

At the same time, the host computer 15 sends the same code to the lock control device 11 of the door 1 via the communication cable 14 (step S 780).

The host computer 15 receives the call code from the key device 10, and can determine which key lock device 11 corresponds to the lock control device 11 of the guest room door. Sending the code to the lock control device 11 is easy.

The lock controller 11 also records the received code in the EEPROM 33.

As a result, the key device 10 is operated by the operation button 21 in front of the light receiving portion 113 and the light emitting portion 112 of the host computer 15. You can change the unlock code to a new number.

Moreover, at this time, the new code is not displayed at all externally, in other words, since the update is performed unknown to the operator performing the code update operation, there is a feature that the reliability is very high.

In addition, it is very easy to update the unique code, it does not require any time and effort to replace the entire lock lock device as in the prior art.

As a result, the code for unlocking can be changed more frequently than before, and reliability can be improved in this respect as well.

Although the embodiments of the present invention have been described above, the lock locking device of the present invention is not limited to these embodiments. For example, the configuration applied to the lock locking device of an automobile door, the front door of an organic device such as pachinko, etc. Configuration, configuration applied to control devices such as remote control that wants to restrict user, configuration that enables not only to unlock the lock but also to lock the lock by the key device, and the main body of the lock has received a regular recognition code for unlocking. It is a matter of course that the configuration lamp including the display means such as lighting the LED can be carried out in various states without departing from the gist of the present invention.

In this embodiment, a unique code or the like is stored, but the EEPROM is used to rewrite the code without removing the PROM from the key device 10 and the lock control device 11, but if the PROM is removed and recorded, Ordinary PROM or fuse ROM can also be used.

In this case, it is conceivable to take out the PROM and duplicate it. However, when generating the recognition code in the key device 10, the algorithm for generating the recognition code is stored in the mask ROM in the CPU provided with the read protection mechanism, even though the PROM is stored. Even if you illegally pick up and copy a unique code, you cannot unlock it.

This is because the correct identification code cannot be output unless the CPU side is duplicated.

Similarly, when judging whether there is a unique code corresponding to the key device 10 among the response codes received from the lock control device 11, the lock code is sent from the lock control device 11, instead of seeing a simple match between the two. If the unique code is converted into a predetermined algorithm and then the coincidence with the unique code stored in the key device 10 is checked, and the same conversion algorithm is stored in a mask ROM equipped with a read protection mechanism, As long as you can't duplicate it, you won't be able to create the right key, and you'll have sufficient reliability.

In these cases, since the reliability of the entire apparatus is improved, there is no problem in reducing the number of unique codes to a few digits.

On the other hand, when the lock lock device is applied to a car door, the lock device may be installed at a dealer shop or the like, and when the lock lock device is applied to a door of a pachinko device, it may be installed in a monitoring room of a hall.

Furthermore, in the present embodiment, when the lock lock device detects a suspicious signal input, the host computer 15 is notified. However, this notification causes the surveillance camera to operate or start recording in the video. Configuration is also possible.

As described above, in the lock locking device of the present invention, it is possible to at least unlock the lock in a non-contact manner, and furthermore, it has an excellent effect of making it impossible to actually make a non-normal copy of the key device.

Although it is possible to unlock in a non-contact manner, it is impossible to duplicate the key device by simply reading the code output from the key device and simply imitating it.

This is because the key device operates by exchanging a code with the lock main body.

Therefore, the lock locking device of the present invention has high reliability and is convenient for use.

According to the structure of the lock lock device of the present invention, the response code is recorded by the recording device at the same time by recording a pair of unique response codes on the key device and the response code output means. Even if it can be rewritten, it is easy to improve the reliability as a lock lock.

Therefore, the lock apparatus handled by an unspecified number of doors, such as a hotel, does not need to replace the whole apparatus, and also the effort and time of replacement are unnecessary.

In addition, when applied to a door such as a pachinko organic device, the code for unlocking the lock can be changed in the pachinko hole, and the reliability is very high.
