[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building door locking / unlocking system for controlling the locking / unlocking state of a building door by transmitting and receiving radio signals between the locking / unlocking device provided on the building door side and each portable device, and more specifically, The present invention relates to a registration system for registering an ID code of each portable device in a locking / unlocking device provided on a building door side.
[0002]
[Prior art]
Conventionally, a door is obtained by transmitting and receiving a radio signal between a locking / unlocking device provided on the door side of the building (door or its vicinity) and a portable device possessed by a resident of the building, an administrator, a specific entry / exit trader, etc. Building door locking / unlocking systems that control the locking / unlocking state of the building are used.
[0003]
In this type of locking / unlocking system, a locking / unlocking device provided on the door side of a building transmits a challenge code signal and a call code signal using electromagnetic waves as a communication medium.
[0004]
When a person who has the portable device enters the propagation area of those signals, the portable device responds to the challenge code signal and the calling code signal and outputs a response code as a radio wave signal.
[0005]
In the case of a manually opened / closed door, the locking / unlocking device includes a transceiver, an electric locking / unlocking mechanism, a lock unit, a controller, etc. When the transceiver of the locking / unlocking device receives a response code signal from the portable device, the controller It is determined whether or not the response code signal is a regular signal, and the electric locking / unlocking mechanism of the door is controlled based on the determination result to lock and unlock the lock portion.
[0006]
In the case of an automatic door, the locking / unlocking device includes a transceiver, an electric door opening / closing mechanism, a controller, and the like. When the transceiver of the locking / unlocking device receives a response code signal from the portable device, the controller Is a regular signal, and the electric door opening / closing mechanism is controlled based on the determination result to open the door.
[0007]
The challenge code signal described above is a signal of an arbitrary random number code generated by the controller, and this code signal is for activating a portable device that is in a pause state.
[0008]
The call code signal is a code signal registered in the controller in association with the ID code of the portable device corresponding to the call.
[0009]
When transmitting the challenge code signal from the transmitter, the controller of the locking / unlocking device creates a response code (internal response code) from the registered portable device ID code and challenge code, and stores the response code in the memory.
[0010]
On the other hand, the portable device that has received the challenge code signal from the locking / unlocking device creates a response code from the ID code registered in advance in the portable device and the received challenge code, and stores the response code in the memory. It is sent back to the locking / unlocking device as a radio signal.
[0011]
In the locking / unlocking device that has received the response code signal from the portable device, the controller obtains the response code (external response code) obtained from the received signal, and the response code (internal response code) stored in the memory in advance. Are compared, and when both coincide, predetermined locking / unlocking operation control is performed.
[0012]
Further, in this type of locking / unlocking system, there is a configuration in which a keyless entry system is incorporated while it can be manually locked / unlocked by a key inserted from a key insertion port of the lock portion.
[0013]
The keyless entry system is configured to remotely control a locking / unlocking device by pressing a transmission switch button of a portable device.
[0014]
That is, when the transmission switch button is pressed, the portable device outputs an ID code signal, and the controller of the locking / unlocking device that receives the ID code signal outputs the received ID code and the registered ID code stored in the memory in advance. In comparison, when these two ID codes match, predetermined locking / unlocking operation control is performed.
[0015]
Furthermore, what provided the touch key in the locking / unlocking apparatus provided in the door side is also known.
In this type of locking / unlocking device, the owner of the portable device does not use the touch key as a key instead of immediately unlocking or locking the electric locking / unlocking mechanism simply by transmitting / receiving a radio signal between the locking / unlocking device and the portable device. When the intention of locking / unlocking is indicated by touching, the electric locking / unlocking mechanism is unlocked or locked on condition that the will is confirmed.
[0016]
Moreover, as a locking / unlocking device for building doors, it is common to intermittently transmit the challenge code signal and the call code signal. However, in order to save electricity, Some are configured to transmit these signals when a touch key is touched.
[0017]
[Problems to be solved by the invention]
In the building door locking / unlocking system, as described above, it is necessary to register the ID code of the portable device in advance in the door-side locking / unlocking device.
[0018]

[0029]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0030]
1 (a) and 1 (b) show an embodiment in which the building door locking / unlocking system of the present invention is applied to a manually openable door of a building.
[0031]
As shown in FIG. 1A, an outer lock portion 11 and an outer door handle 12 of the locking / unlocking device are provided on the outer surface of the door 10, and the door 10 is embedded so as to be embedded in the locking / unlocking device. A controller 14 is provided. 50 is a portable device.
[0032]
The outer lock 11 has a cylinder lock key insertion part 15, a touch switch 16, a lock / unlock display part 17, and a code signal transmission / reception part 18 on the front face thereof.
[0033]
Although not shown in the drawings, the outer lock portion 11 includes a transmission antenna, a reception antenna, a capacitor, a switch portion of a touch switch, and the like.
[0034]
The transmission antenna in the outer lock 11 is formed by winding a conductive wire around a magnetic material, and a series resonance circuit is formed by the transmission antenna and a capacitor.
[0035]
That is, the challenge code signal and the calling code signal are repeatedly transmitted from the transmission antenna sequentially using the resonance current of the series resonance circuit.
[0036]
The challenge code signal and the call code signal are transmitted as an LF (125 kHz) electric field signal using, for example, an electromagnetic wave having a high distance attenuation in consideration of radio interference to peripheral wireless devices.
[0037]
The receiving antenna in the outer lock 11 is a known antenna made of a rod-shaped conductor, and a high-frequency radio wave transmitted from the portable device 50 (see FIG. 1), for example, a response code signal of RF (315 MHz) is a radio signal. As received.
[0038]
The portable device 50 has a transmission switch button 51 for transmitting a code signal for keyless entry. When this transmission switch button 51 is pressed, the portable device 50 is stored in the portable device 50 in advance. The ID code can be encrypted into an ID code signal and transmitted as a wireless signal.
[0039]
And the receiving antenna in the outer side lock part 11 can receive the ID code signal from the portable device 50 similarly as a radio wave signal.
[0040]
The display unit 17 displays green light in the locked state and red light in the unlocked state, so that the person who locks and unlocks can visually confirm the locking and unlocking.
[0041]
The transmission / reception signal of the outer lock portion 11 is processed by the controller 14.
[0042]
That is, the controller 14 has a control circuit having a memory (storage means) such as RAM and ROM, a timer, etc. in addition to the CPU, and locks the challenge code signal and the call code signal under the control of the controller 14. The signal can be output from the transmission antenna in the unit 11.
[0043]
The challenge code signal is an arbitrary random number code signal.
[0044]
Further, the call code signal is generated from the call code set in advance in the controller 14 in accordance with the order of registration in the controller 14 of the portable device 50, and is stored and held in the memory corresponding to the ID code of the portable device 50. To do.
[0045]
The controller 14 also inputs a response code signal received by the receiving antenna in the outer lock 11 and compares the response code with the internal response code generated from the transmitted challenge code and stored in the memory. When these codes match, the unlock preparation mode is set.
[0046]
The response code signal is a code signal calculated in the same manner as the locking / unlocking device side from the ID code of the portable device 50 and the received challenge code, and is output from the portable device 50.
[0047]
Furthermore, when the controller 14 operates the touch switch 16 in the unlocking preparation mode, the controller 14 unlocks the electric drive unit of the locking / unlocking mechanism 20 in response to the input of the switch signal, and the dead bolt 21 is in the locked state. Exit and unlock.
[0048]
When the door is opened / closed after unlocking, or when the door is not opened / closed within a predetermined time, the controller 14 controls the electric drive unit of the locking / unlocking mechanism 20 to lock the door.
[0049]
The outer door handle 12 shown in FIG. 1 has a structure in which a latch mechanism is interlocked. For example, in the case of a pull-open door 10, when the door handle 12 is pulled, a latch bolt (not shown) moves backward to move the door. Can be opened. Further, when the pulling operation of the door handle 12 is released, the latch mechanism automatically returns.
[0050]
The controller 14 includes a registration switch 22, and the registration switch 22 can be switched by a tool such as a pin 24 inserted from a small hole 23 opened in the end surface on the free short side of the door 10. In the small hole 23, a removable plug, for example, a small screw 25 is screwed and attached.
[0051]
FIG. 2 is a flowchart showing processing operations of the controller and the portable device when the portable device is registered in the locking / unlocking device in the building door locking / unlocking system.
[0052]
As shown in FIG. 2, when the registration switch 22 is pushed, the controller 14 of the locking / unlocking device first sets (starts) a timer set for 30 seconds, for example, and the wireless signal code from the portable device 50 A reception wait state is entered (ST100, ST101, ST102).
[0053]
On the other hand, as described above, when the transmission switch button 51 is pressed, the portable device 50 reads a unique ID code stored in advance in a memory (storage unit), calculates the rolling code, encrypts it, Further, it is converted into a high-frequency radio signal (RF code signal) and transmitted (ST200, ST201, ST202, ST203).
[0054]
After transmitting the RF code signal, portable device 50 enters a reception standby state, that is, a stop mode state (ST204).
[0055]
When the outer lock portion 11 of the locking / unlocking device receives the RF code signal from the portable device 50, the controller 14 determines whether to receive the RF code signal (ST102).
Then, an ID code (registered ID code) is read from the RF code signal, and a call number (call code) corresponding to the ID code is set (ST104).
[0056]
Then, the registration ID code and the call code (call number) are temporarily stored in the memory (storage means), and converted into a call setting code created by adding the call code (call number) to the registration ID code. The signal is changed to a low frequency signal (LF code signal) and transmitted from the outer lock 11 (ST105).
[0057]
After transmitting the LF code signal, the controller 14 waits for an RF code signal from the portable device 50 (ST106).
[0058]
On the other hand, when the portable device 50 receives the call setting code signal (LF code signal) from the outer lock portion 11, the portable device 50 reads the ID code (reception ID code) included in the call setting code signal, and the portable device 50. It is determined whether or not the ID code (transmission ID code) transmitted from the ID matches the received ID code (ST205, ST206).
[0059]
When the transmission ID code matches the reception ID code, the portable device 50 reads the call code (call number) included in the received call setting code signal and stores (registers) it in the memory. (ST207).
[0060]
Thereafter, as in step ST203, portable device 50 transmits an RF code signal including an ID code (transmission ID code) and enters a stop mode (ST208, ST209).
[0061]
When the controller 14 of the locking / unlocking device receives the RF code signal from the portable device 50, the ID code (reception ID code) included in the RF code signal and the ID code (registration) stored in the memory at the previous reception are registered. ID codes) are compared (ST106, ST108).
[0062]
If the received ID code matches the registered ID code, the registered ID code is stored (registered) in the memory as a formal ID code (ST109).
[0063]
After that, the controller 14 notifies registration completion, for example, outputs a buzzer sound or turns on the display unit 17, and then returns to step ST101 to register another portable device (ST110).
[0064]
The controller 14 starts a predetermined set time (for example, 30 seconds) in step ST101 and then times out without receiving an RF code signal in step ST102 (ST103), or the RF code in step ST106. When a timeout occurs without receiving a signal (ST107), for example, the end of the registration mode is notified by a buzzer sound or the like, and then the normal mode is restored (ST111, ST112).
[0065]
On the other hand, if the transmission ID code does not match the reception ID code in step ST206, portable device 50 proceeds to the stop mode without registering the call code (call number) (ST209).
[0066]
As described above, in the building door locking / unlocking system according to this embodiment, the controller 14 of the locking / unlocking device provided on the building door 10 side is switched to the registration mode by the registration switch 22, and then transmitted by the portable device 50. The portable device 50 can be registered in the locking / unlocking device with a simple operation by simply operating the switch button 51.
[0067]
In addition, the controller 14 sets a call code corresponding to the ID code received from the portable device 50 when the registration switch 22 is set to the registration mode, stores the call code in the memory (storage means), and calls the call code in the received ID code. Is transmitted to the portable device 50. On the other hand, the portable device 50 stores the call code read from the received call setting code signal in the memory (storage unit). Can be registered.
[0068]
Although detailed description has been omitted in the above description, preferably, portable device 50 stores the call code in the memory in step ST207 and then includes the ID code and the call code stored in the memory in ST208. The setting code signal is configured to be transmitted as an RF code signal.
[0069]
The controller 14 of the locking / unlocking device preferably receives the ID code (registered ID code) received last time and the ID code (received ID code) received this time when receiving the RF code signal which is a call setting code signal in step ST106. ) In step ST108, it is determined whether the set call code (registered call code) and the currently received call code (received call code) match, and the ID code and The ID code is configured to be stored in the memory when both of the calling codes match.
[0070]
According to the above configuration, the controller 14 of the locking / unlocking apparatus officially stores the ID code in the storage means only when both the ID code and the calling code match, so it is more reliable and more reliable. You can register.
[0071]
Further, the controller 14 of the locking / unlocking device described above preferably stores one first call code different for each locking / unlocking device in the storage means in advance, and the order in which the calling code is registered in step ST104. The first call code is changed to have a predetermined relation within a certain range, and is registered in the memory.
[0072]
According to the above configuration, the first call code that is initially set for each locking / unlocking device is different, and the first call code is changed so as to have a predetermined relationship within a certain range. Even if there is a mobile device registered in another locking / unlocking device, it is possible to prevent the wrong response code signal from an unrelated mobile device from being received by making the call code different and to prevent malfunction due to interference. Can be prevented.
[0073]
More specifically, when registering and moving a plurality of portable devices, if the plurality of portable devices are close to each other, radio waves return from the plurality of portable devices at a time, causing interference and locking / unlocking device. The outer lock 11 and the controller 14 may not be able to read well and may not move.
[0074]
The call code (call number) for each portable device 50 is generally numbered according to the registered order. In this case, if eight portable devices 50 are registered, the portable devices 50 are numbered from No. 1 to No. 8, and if the calling code of that number does not come, the portable device 50 transmits radio waves (response code signals). Configured not to return.
[0075]
That is, the locking / unlocking device is called in order from No. 1, and if No. 1 is called and no radio wave is returned, No. 2 is called.
[0076]
However, for example, in the case of simple serial numbers from 1 to 8, all the registered portable devices 50 are numbered from 1 to 8, and another portable device registered in another locking and unlocking device tries to operate. If it is near the outer lock 11 of the locking / unlocking device (in the signal propagation area), it may be the same as the calling number (calling code) of the portable device corresponding to the original locking / unlocking device. Resulting in.
[0077]
Therefore, in the preferred embodiment of the present invention, as described above, the call number (call code) that is first created by the controller 14 of the locking and unlocking apparatus is set to a random number.
[0078]
For example, the first is 157. The number is created by the controller 14 of each locking / unlocking device at the time of registration and transmitted to the portable device 50. Further, the number is incremented by 1 for additional registration, such as 158 for the second and 159 for the third.
[0079]
By setting the call number as described above, even if there is a portable device registered in another locking / unlocking device, the call number (call code) will be different, so there is no possibility of interference. It is.
[0080]
Further, in the configuration of the above embodiment, the controller 14 is installed inside the door 10 of the building, and the registration switch 22 is operated by a switch that is inserted through a small hole 23 that opens in the end face of the door 10. In addition, since the small hole 23 on the end face of the door 10 is closed with a removable plug 25, the risk of unauthorized operation of the registration switch 22 can be avoided, and When registering the machine 50, the registration switch 22 can be easily operated by removing the plug 25 from the small hole 23. Therefore, it can be set as the door locking / unlocking system for buildings excellent in operativity and safety.
[0081]
Although the illustrated embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made.
[0082]
For example, when the registration switch 22 is pressed, all previously registered ID codes may be deleted (that is, the controller 14 is reset).
[0083]
Further, when the lock / unlock command code is attached to the ID code signal transmitted from the portable device 50 at the time of registration, the lock / unlock command code is canceled by pressing the registration switch 22. Can do.
[0084]
Furthermore, the door side locking / unlocking device may transmit a challenge code signal and a call code signal by pressing the touch switch 16.
[0085]
Furthermore, the controller 14 in the door-side locking / unlocking device may be configured to sound or display a buzzer for the ID code already registered when the ID code registration is completed.
As a result, the user can easily recognize the number of ID codes already registered.
[0086]
The memory (storage unit) of the portable device 50 can be configured to store a plurality of call codes. Thereby, since the calling code corresponding to the plurality of doors in one house can be stored, the plurality of doors can be locked and unlocked by one portable device 50.
[0087]
Furthermore, a plurality of ID codes can be stored in the memory (storage unit) of the portable device 50. In this case, if a predetermined ID code is transmitted when a predetermined call code is received, security is improved when there is a common door (door) other than the home entrance door, such as a condominium such as an apartment. Can be made.
[0088]
Furthermore, the door of the building to which the present invention is applied may be an automatic opening / closing door.
[0089]
【The invention's effect】
As is apparent from the above description, according to the present invention, it is possible to provide a building door locking / unlocking system capable of easily and reliably registering a portable device.
