Description

  The present invention relates to an electric shutter device, and more particularly to an electric shutter device that can be operated wirelessly.

  Conventionally, an electric shutter that can be operated wirelessly by radio waves using a remote controller is known (Patent Document 1). An electric shutter that can be operated wirelessly can be operated only from a registered remote controller from the viewpoint of crime prevention. The electric shutter is installed in an opening of a building or the like, but there may be a plurality of openings, and in that case, a plurality of electric shutters may be installed.

  In such a case, it is necessary to register which remote controller can operate which electric shutter among a plurality of electric shutters.

  Conventionally, there are the following methods for registering the relationship between the electric shutter and the remote control. First, as a method of registering an unregistered remote controller in an already-installed electric shutter, there is a method of turning off the power of an electric shutter other than the target so as not to register other than the target electric shutter. In addition, there is a method of registering a correspondence relationship by simultaneously operating both the remote controller and the electric shutter (for example, registering with the remote controller after making the target electric shutter registerable). In addition, there is a method in which an ID (identification information) set in advance on a remote controller or an electric shutter is input and registered. Moreover, as a method of registering before construction, there is a method of setting a registration relationship from the time of shipment.

Japanese Patent No. 2938050

  The method of turning off the power of an electric shutter that is not subject to registration is complicated. Also, the method of operating both the remote controller and the electric shutter is complicated. And the method of registering in advance requires managing the remote controller and the electric shutter by a combination thereof, which is also complicated.

  The present invention has been completed in view of the above circumstances, and it is an object to be solved to provide a method for easily registering a correspondence relationship with an operation device (so-called remote controller) that can be operated wirelessly in an electric shutter. .

Chi also, the registration preparation reply signal is a signal including the identification information in the other device of said registered preparation information relating to the signal strength of the interrogation signal and the first and second communication unit.

  When registering the relationship between the operating device and the electric shutter device main body (target operated by the operating device), the signal strength of the communication signal used for transmission and reception is used, so that between the operating device and the electric shutter device main body. You can register between the best radio conditions. A person who performs registration (registrant) can improve the radio wave condition between the operation device and the electric shutter device main body, for example, by simply bringing the operation device and the electric shutter device main body close to each other, and can perform registration easily and reliably. .

  The electric shutter device of the present invention will be described in detail according to the following embodiments. The electric shutter device of the present embodiment includes an electric shutter device main body installed in an opening of a building and a remote controller (operation device) that can operate the electric shutter device main body wirelessly. The electric shutter device main body is a device that can open and close a shutter curtain (a part of the shutter main body; in addition, a guide rail or the like) by a driving device such as a motor. The driving device is controlled by the first control unit.

  The shutter curtain can be opened and closed with an operation switch connected by wire to the electric shutter device body, or with a remote control that can be operated wirelessly. The remote control is controlled by the second control unit and has an operation unit operated by the user.

  In addition to opening and closing the shutter curtain, the slat can be opened and closed with the remote control. The electric shutter device main body and the remote control each have a communication unit capable of bidirectional communication. Specifically, the first control unit of the electric shutter device main body has a first communication unit, and the second control unit of the remote control has a second communication unit. Each communication unit includes an antenna and can transmit and receive radio waves. The first communication unit and the second communication unit can transmit and receive signals to and from each other. In addition to the radio wave, a device that performs communication by transmitting / receiving light rays (such as infrared rays) may be used.

  In addition to one or more “operation switches” for opening and closing the shutter curtain, the operation part of the remote control means “registration start / registration switch” which means the start and final registration of the registration process, and means cancellation of the registration process A “registration cancel switch” is provided. Instead of providing a “registration start / registration switch”, the “operation switch” can be replaced with a special operation, such as a special operation such as multiple presses or long presses. A “registration start / registration switch” can be provided and an additional condition added to the operation of the “registration start / registration switch”.

  The correspondence relationship between the remote controller and the electric shutter device main body is not registered at the time of shipment. After the correspondence relationship is registered by the method described below, the registration relationship is maintained unless particularly updated. The electric shutter device main body can be operated only from a registered remote controller. Furthermore, it is possible to register a plurality of remote controllers with respect to one electric shutter device main body and to register a plurality of electric shutter device main bodies with one remote controller.

A method for registering the relationship between the electric shutter device main body and the remote control will be described below. The registration process is performed by a registration device that includes a first control unit and a second control unit.
(1) When there are a plurality of electric shutter device main bodies (those not registered with a remote control), one remote controller is registered in association with a specific (one) electric shutter device main body. Keep all the power on. The electric shutter device main body in which the remote controller is not registered is in a state in which the correspondence relationship of the remote controller can be registered by turning on the power (remote controller registration mode).

Registration Preparation Step When the “registration start / registration switch” in the operation unit of the remote control is operated, the second control unit transmits a “registration preparation inquiry signal” from the second communication unit. When the electric shutter device main body is in a state where it can be registered, upon receipt of this "registration preparation inquiry signal", the signal strength of the "registration preparation inquiry signal" and its own identification information are displayed as a "registration preparation reply signal". Send as. Since the plurality of electric shutter device main bodies are in a registerable state, when a “registration preparation inquiry signal” is received, a “registration preparation response signal” is transmitted.

  As identification information to be included in the “registration preparation response signal”, if identification information unique to each electric shutter device body is stored, the identification information is used as it is. If not registered, it is based on a random number or the like. Use the created one. When creating based on random numbers, create identification information of sufficient length so that duplication of identification information does not occur between each electric shutter device main body, or identification information transmitted by another electric shutter device main body The identification information that does not overlap with it is created. Adequate resolution is adopted for the signal strength of the “registration preparation inquiry signal”. For example, about 100 steps, about 500 steps, about 1000 steps, etc. can be adopted.

  The “registration preparation response signal” is transmitted by being multiplexed by some method so as not to interfere with a signal transmitted by another electric shutter device main body. For example, to prevent interference by waiting for a length based on random numbers or a length corresponding to the magnitude of the received signal strength after receiving the “registration preparation inquiry signal” and shifting the timing of signal transmission Can do. In the unlikely event that the signal transmission is duplicated, the remote control sends a signal requesting retransmission of the “registration preparation reply signal” or sends the above “registration preparation inquiry signal” again. Signal "can be received normally. In addition, if the remote control becomes a signal that cannot be recognized at all due to the overlap of the “registration preparation response signal”, it is impossible to request retransmission, so the registration procedure proceeds for a certain period of time in preparation for such a case. If you don't, you can cancel the registration process. Furthermore, when each motorized shutter device itself is transmitting a “registration preparation response signal”, it is determined whether other motorized shutter devices are transmitting signals that may cause interference. It is also possible to retransmit the “registration preparation reply signal” when it is determined that this can be caused.

  When the remote controller cannot receive the “registration preparation reply signal” within a certain time after transmitting the “registration preparation inquiry signal”, the remote control does not proceed to the subsequent steps and ends the registration step.

Registration Completion Step The second control unit of the remote controller receives a “registration preparation reply signal” using the second communication unit. When the received second “registration preparation reply signal” is received, the second control unit of the remote controller stores the identification information included in the signal as registration identification information. When there are a plurality of received “registration preparation response signals”, the identification information corresponding to the largest signal strength among the signal strengths included in these signals is set as the registration identification information. The remote controller can grasp the number of electric shutter device bodies that can be registered that exist in an operable range according to the type of the received “registration preparation reply signal”.

  The obtained registration identification information is used for registering a combination as follows. (i) By storing the registration identification information in itself, the second control unit can associate the electric shutter device body corresponding to the registration identification information with itself. (ii) Instead of (or in addition to) this operation, the second control unit can transmit a signal including registration identification information (registration identification information signal) toward the electric shutter device body.

  The main body of the electric shutter device that has received the “registration identification information signal” registers that it is associated with the remote controller when the registration identification information included in the signal is the same as the identification information transmitted by itself. If the registered identification information is different from its own identification information, there is another electric shutter device main body, and it is determined that the electric shutter device main body is registered, and then the own identification information is used as the registered identification information. Do not register even if it is sent. In addition, when adopting the registration correction process mentioned later, it prepares for a registration correction process, and makes it the state which can receive the signal used in a registration correction process for a fixed time.

  Here, as an example of a method for determining whether or not the operation signal transmitted when the remote controller is operated is for itself (registered with respect to itself), registration identification information is added to the operation signal and the electric shutter is operated. When the device body compares its own identification information with the added registered identification information, the device body accepts the operation as a registered remote controller, or the identification information set for each remote controller is The operation is performed when the remote control identification number stored in the electric shutter device main body matches with the remote control identification number stored in the first control unit of the shutter device main body and transmitted by adding the remote control identification information to the operation signal. Can be accepted, or both can be combined.

  After this registration, it is possible to prevent the new remote controller from being registered so as to correspond unless there is an instruction for additional registration of a new remote controller from the remote controller. When transmitting the signal (ii), the remote controller can transmit its own identification information, and the identification information of the remote controller is stored in the first control unit. In addition, after the combination of the first control unit and the second control unit corresponding in the registration completion step is determined, an encryption key or the like can be exchanged in order to improve the safety of subsequent communication. Thereafter, spoofing using the exchanged encryption key can be prevented. Although the encryption method is not particularly limited, an operation signal is obtained by exchanging a unique secret key or public key in advance, and continuously changing these keys (time data, operation frequency data, etc.). A method of creating encrypted data that can be used only once by encrypting. Use of continuously changing data makes it impossible to reuse previously used encrypted data, thereby improving safety.

  Here, the principle of registration will be described. It can be inferred that the “Signal preparation inquiry signal” transmitted from the remote controller is received closest to the signal having the highest signal strength. Therefore, by continuing the registration process assuming that the electric shutter device body showing the highest signal strength is the object of registration, the electric shutter device body closest to the remote controller can be combined and registered with the remote controller. Therefore, when registering the remote controller, if it is guided that the electric shutter device body to be registered is as close as possible, the registration can be performed in a desired combination. In addition, even if a person who does not know the matter of registering in close proximity performs the registration process, it is natural to perform the registration process while bringing it close to the electric shutter device body to which the remote controller is to be combined, As a result, there is a high possibility that the desired combination can be realized.

  It should be noted that the registration process can be terminated if the electric shutter apparatus body cannot receive the registration identification information within a predetermined time after transmitting the “registration preparation reply signal”.

-Notification process After a registration completion process, it notifies a registrant so that the electric shutter device main body registered as a combination can be found. Examples of the notification method include sound, an operation such as opening and closing a shutter curtain, and light blinking. It is clear which electric shutter device body is registered if the remote control is actually operated, but registration can be performed without stress by prompt notification.
Registration Correction Step Further, the registered combination can be canceled by operating the “registration cancel switch” of the remote controller after the notification step (for example, within a predetermined time after the notification operation). Conversely, a “registration switch” may be provided so that registration is not completed unless the registration switch is operated within a certain time after the notification process. When the registration switch is not operated, the same operation as when the “registration cancel switch” is operated can be performed, and the registration process itself can be terminated by stopping the registration.

  The combination is canceled by deleting information registered in the remote control and / or the electric shutter device main body, or registering that the registration is canceled although not deleted. After canceling the registration, the remote controller uses the identification information included in the “registration preparation reply signal” including the next highest signal intensity transmitted from the canceled electric shutter device main body as new registration identification information. Then, similar to the procedure described above using this registration identification information, an operation of registering the electric shutter device main body corresponding to the registration identification information as a combination target is performed. The registrant can easily realize the desired combination by simply operating the “registration cancel switch” until the desired combination is realized.

・ The process of adding a new remote controller to the motorized shutter device body that has been registered and registering the remote controller. Do you provide a dedicated switch on the remote control unit, or do you operate the switch in a specific combination? Thus, a signal is transmitted to the electric shutter device main body to make it possible to perform additional remote control registration. Subsequent operations are as described above. By this step, a plurality of remote controllers can be registered for one electric shutter device main body.

・ Additional registration of remote control registered in one motorized shutter device main body to another motorized shutter device main body Can be registered. By this step, a plurality of electric shutter device bodies can be registered for one remote controller. By combining with the method for registering a plurality of remote controllers in the registered electric shutter apparatus main body described above, it is possible to register the plurality of electric shutter apparatus main bodies and the plurality of remote controllers so as to correspond to each other in any combination. For example, when one remote controller is registered corresponding to a plurality of electric shutter device main bodies, if it is desired to add a new remote controller to only a part of them, the remote controller is operated to allow additional registration of the remote controller And all the electric shutter device bodies that support the remote control can register additional new remote control, but in the above process, only one of them can be registered, so register the desired combination Can do.
(2) When there is a plurality of remote controllers and one electric shutter device main body is registered in association with a specific (one) remote controller (when the first control unit of the electric shutter device main body is operated)
Since the description described in (1) can be used as it is except that the relationship between the remote controller and the electric shutter device main body is reversed, the detailed description is omitted.

  The electric shutter device of the present invention will be described below based on examples. The electric shutter device of the present invention includes a remote controller 1 and an electric shutter device body 2 as shown in FIG. The remote controller 1 has a second control unit 11, an operation unit 12, and an antenna 13. The second control unit 11 includes a second communication unit 111, a timer 112, and a memory 113. The operation unit 12 has a registration start / registration switch 121 and a registration cancel switch 122, and transmits to the second control unit 11 that these switches have been operated. The antenna 13 is connected to the second communication unit 111.

  The electric shutter device body 2 includes a first control unit 21, a drive unit 22, a shutter body 23, and an antenna 24. The shutter body 23 has a shutter curtain (not shown) and a guide rail (not shown) for guiding the shutter curtain. The drive unit 22 is a device that winds up and rewinds the shutter curtain, and is controlled by the first control unit 21. The first control unit 21 includes a first communication unit 211, a timer 212, and a memory 213. The antenna 24 is connected to the first communication unit 211. The first communication unit 211 can transmit and receive signals to and from the second communication unit 111. The timers 112 and 212 are used for determining the passage of time (used when determining the passage of a fixed time in a process described later). The memories 113 and 213 are used as work memories for the first and second control units 11 and 21, and some of them are nonvolatile, and information on correspondence correspondence is stored.

  A method (registration process) for registering the remote controller 1 in one of the plurality of electric shutter device bodies 2A to 2C (registered in the electric shutter device body 2B in the following example) will be specifically described below. The registration process generally proceeds as follows (FIGS. 2 to 4). The signal intensity is 1 to 10 levels, 1 being the weakest and 10 being the strongest.

  First, the remote controller 1 transmits a registration preparation inquiry signal (registration preparation process: FIG. 2a, FIG. 3: S1, S2). The electric shutter device bodies 2A to 2C that have received the registration preparation inquiry signal respectively transmit registration preparation response signals (the signal strength of the received registration preparation inquiry signal and its identification information (ID)) (registration preparation step: FIG. 2b, FIG. 4: C1, C2). The electric shutter device main body 2A transmits a registration preparation response signal that the signal strength is 8 and the ID is 10000, and the electric shutter device main body 2B transmits a registration preparation response signal that the signal strength is 10 and the ID is 00000. Then, the electric shutter device body 2C transmits a registration preparation reply signal that the signal intensity is 4 and the ID is 99999 (FIG. 4: C2). The remote controller 1 recognizes that there are three electric shutter device bodies 2 that can be registration candidates, and determines that the identification information corresponding to the signal strength having the highest signal strength is ID00000 corresponding to the signal strength 10. (Registration completion step: FIG. 2b, 2c, FIG. 3: S3).

  The remote controller 1 transmits ID00000 as registration identification information (registration completion process: FIG. 2c, FIG. 3: S4). Of the electric shutter device main bodies 2A to 2C, the electric shutter device main body 2B whose registration identification information 00000 matches its own ID sounds a buzzer and opens and closes the shutter curtain as being registered (notification process: FIG. 2d, FIG. 4: C3, C4). Since the electric shutter device body 2B is a combination to be registered, the registration start / registration switch 121 of the remote controller 1 is operated (FIG. 3: S5), and the registration is completed (registration completion signal is transmitted FIG. 3: S6). The electric shutter device body 2B performs the registration operation (FIG. 4: C6) as if it were registered, and the other electric shutter device bodies 2A, 2C end the registration process assuming that they are not registered (registration completion step). : FIG. 2e, FIG. 4: C7). If the remote controller 1 is not operated for a certain period of time, the registration process is canceled as there is no intention to continue registration (FIG. 3: S7, FIG. 4: C7).

  Here, if the registration cancel switch 122 is operated within a certain time after the notification process, the registration to the electric shutter device main body 2B is canceled, and the ID 10000 of the electric shutter device main body 2A having the next largest signal strength is used as the registration identification information. The steps shown in FIGS. 2c to 2e are repeated until the desired electric shutter device body 2 is selected.
