[Prior art]
2. Description of the Related Art In general, some electric shutters that open and close a shutter curtain by forward and reverse driving of an electric motor include an opening and closing operation (including a stop operation) that transmits a medium that propagates in the air such as radio waves, light waves, and sound waves. In some cases, control is performed by receiving a control signal from a transmitter of the formula.
In this case, in addition to security problems, if the shutter curtain is of a double type, or if there is a similar thing in the neighborhood, one transmitter can not open and close the other shutter curtain. Care must be taken to prevent this from happening. Therefore, conventionally, while setting to transmit a unique code signal to the transmitter together with the control signal, the unique code signal is registered in the receiving unit side, and when the registered unique code signal is received, While opening / closing control of the shutter curtain is performed based on the input control signal, opening / closing control is not performed when a code signal different from the registered unique code signal is input.
However, there is a demand to allow a plurality of transmitters to control the opening and closing of one shutter curtain, and to allow the opening and closing of a plurality of shutter curtains to be controlled by a single transmitter. The side will additionally register the unique code signal. Such new registration of the unique code signal is problematic in terms of crime prevention and the like.
Therefore, conventionally, the receiving unit is first switched to a code registerable mode, and an operation for registering a new unique code signal is performed in this mode state. This operation is performed by using an existing transmitter (first transmission). The receiving unit is further switched from the code registration mode to the code registration mode by inputting the required operation signal of the device, and then the receiving unit receives the required operation signal from the transmitter for which the unique code signal is to be registered. The unique code signal of the transmitter is provisionally registered, and thereafter, the temporarily registered unique code signal is set to be formally registered based on the input of the required operation signal from the first operated transmitter. Was.

[Problems to be solved by the invention]
However, the above-mentioned conventional device is a device in which the temporarily registered unique code signal is registered properly after the input of the required operation signal from the first transmitter is finally input. When there are a large number of devices, it is sometimes difficult to determine which one is the first transmitter, and in that case, it is necessary to start over from the beginning, and there is a problem that the operability is poor.
In addition, in the conventional device, the return from the code registration mode to the normal control mode is set after a preset timer time (for example, 5 minutes) has elapsed since the last code registration. As a result, for example, when it is desired to register each different transmitter for adjacent shutters, after completing the registration work for one shutter, if the registration work is performed for the next shutter before the timer time elapses. However, there is a fear that the unique code signal for the next registration work may be registered in the shutter that has been previously registered, so that it is necessary to wait for the timer time to elapse, resulting in poor workability. There are problems to be solved by the present invention.
[0004]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention has been made to solve these problems in view of the above-described circumstances, and an invention according to claim 1 is characterized in that a unique code signal incorporated in a transmission signal from a transmitter is transmitted to a receiving unit. In the wireless electric shutter configured to perform the opening and closing control of the corresponding shutter curtain in the unlocked state when already registered on the side, the receiving unit includes a memory for registering a plurality of unique code signals. In registering the unique code signal in the memory, the receiving unit can perform mode switching between a normal control mode for executing opening / closing control of the shutter curtain and a unique code registration mode for registering the unique code signal. When the mode is switched to the code registration mode, it is determined whether or not there is an input of a unique code signal. The de signal temporarily registered, if different from the unique code signal unique code signal is the previously temporarily registered to enter after which the provisional registration, temporarily registers the unique code signal comprising said different, this register the specific code signals these temporary registration The wireless electric shutter is characterized in that the end signal for performing the operation is set to the signal output again from the transmitter that was last registered, and is set to return to the normal control mode when the main registration is completed. It is.
Then, the present invention prevents such a problem that a transmitter for outputting a registration end signal cannot be determined or a unique code signal is registered even though the registration work has been completed. It can be avoided and the registration work can be performed smoothly.
According to a second aspect of the present invention, in the first aspect, in the registration of the unique code signal in the unique code registration mode, it is determined whether or not the originally input unique code signal has been registered. A wireless electric shutter characterized in that it is set so as not to be accepted unless it is determined that the shutter has been performed.
By doing so, it is possible to prevent additional registration without knowing.

BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a shutter curtain of an electric shutter, and the shutter curtain 1 is wound and unwound based on a rotation operation of a winding shaft 3 by forward and reverse driving of an electric switch 2. And the opening and closing operation of the opening is the same as in the prior art.
[0006]
Reference numeral 4 denotes a drive control unit for controlling the opening / closing drive of the switchgear 2, reference numeral 5 denotes a receiving unit having a receiver 6, and reference numeral 7 denotes a transmitter. The control signal transmitted from the transmitter 7 is received by the receiver 6. Then, the received control signal is input to the receiving unit 5. On the other hand, the receiving unit 5 includes a mode changeover switch 8 for changing the mode from the "normal control mode" to the "unique code registration mode". When the mode changeover switch 8 is in the "normal control mode", the receiving unit 5 transmits the control signal together with the control signal. It is determined whether the unique code signal transmitted from the device 7 matches the registered one, and when it is determined that the unique code signal matches, the transmitted control signal is the open, close, or stop signal. The drive control unit 4 outputs a control signal corresponding to the determined signal to the drive control unit 4 and outputs a corresponding control signal to the switchgear 2 based on the control signal. The control is executed, but since the control procedure in the normal control mode is a general-purpose procedure, further details are omitted.
[0007]
Next, when the mode changeover switch 8 is operated to switch to the "unique code registration mode", the timer T of the receiving section 5 starts first. Incidentally, switching from the normal control mode to the unique code registration mode is performed without using a mode changeover switch as in the present embodiment, for example, when there is an input of another preset control signal or when an operation switch is turned on. When there is a changeover, for example, the main power supply may be switched from OFF to ON, and may be automatically switched after the initial setting is performed. Such a setting may be appropriately executed as necessary. it can. The unique code registration mode is automatically switched to the normal control mode when a preset timer time T (set as, for example, 5 minutes as a registrable time) has elapsed since the start of the timer T. Is set to Furthermore, even if the timer time is within the time T, it is set to automatically switch from the unique code registration mode to the normal control mode when the main registration described later is completed. When a signal other than the input is input, it can be set to automatically switch to the normal control mode and execute the corresponding opening / closing control.
Then, in the specific code registration mode, a predetermined operation signal (for example, a stop signal and a signal continuous for 3 seconds or more) is transmitted from a transmitter (hereinafter, referred to as a first transmitter 7a) within the timer time T. It is determined whether or not an input has been made. If it is determined that the input has been made, the unique code signal (first unique code signal) of the first transmitter 7a is temporarily registered.
In this unique code registration mode, before the timer time T further elapses, a predetermined operation signal is input, which is the same as the previously temporarily registered unique code signal, that is, the same as the first unique code signal. It is determined whether there is. When it is determined that they are the same, the temporarily registered first unique code signal is permanently registered in the memory of the receiving unit 5 (if the temporarily registered first unique code signal is already registered, Ignoring this, or deleting the registered unique code signal and newly registering the first unique code signal, the same applies hereinafter), and switching to the normal control mode.
[0008]
On the other hand, when the input predetermined operation signal is different from the temporarily registered first unique code signal, the temporarily registered first unique code signal is temporarily registered (temporarily registered as the second unique code signal). Then, while waiting for the input of the predetermined operation signal, if the input predetermined operation signal is the same as the one previously provisionally registered (that is, the second unique code signal), the unique code signal provisionally registered so far is used. Register, and if they are not the same, perform tentative registration (third unique code signal). And, in this way, when the latest input predetermined operation signal is different from the previously provisionally registered signal, the provisional registration of these unique code signals is repeated, and if the same as the previously provisionally registered signal, Assuming that the temporary registration of the unique code signal has been completed, the setting is made such that each temporarily registered unique code signal is permanently registered in the memory of the receiving unit 5 and returned to the normal control mode.
In this embodiment, the setting of the erasure of the registered unique code signal can be executed by operating the erasure switch 9 provided in the receiving unit 5. That is, in this device, when the erase switch 9 is turned on for more than a preset time (for example, 3 seconds), all the unique code signals other than the transmitter 7a registered first are erased. When the erasure switch 9 is turned on for more than a preset time while only the unique code signal of the first registered transmitter 7a is registered, the first registered transmitter 7a Are deleted so that no registered code signal is registered.
[0009]
In the apparatus configured as described above, the opening / closing control of the shutter curtain 1 is executed based on the transmission of a control signal from the transmitter 7. However, when a new transmitter 7 is to be registered, a unique code registration mode is set. , And in this state, a predetermined operation signal is output from the first transmitter 7a selected first, and then a predetermined signal is transmitted from the transmitter 7n, which is to be sequentially registered as the second transmitter 7b, the third transmitter 7c,. By outputting an operation signal and finally outputting a predetermined operation signal from the same transmitter 7n that was operated last time, that is, outputting a predetermined operation signal twice using the last transmitter 7n, The registered unique code signal is fully registered, and the control returns to the normal control mode.
[0010]
As described above, according to the embodiment of the present invention, when it is desired to register the unique code signal of the transmitter 7, a predetermined operation signal is input using the transmitter 7a which is operated first as in the related art. Rather, the operation is performed by inputting a predetermined operation signal twice from the transmitter 7n operated last, so that there is no problem that the first transmitter 7a cannot be identified. Can be smoothly performed.
[0011]
Furthermore, since this device is configured to automatically return from the unique code registration mode to the normal control mode when the main registration is completed, for example, when it is desired to register each transmitter for each of the close shutters, one is required. Even if the registration work for the next shutter is performed immediately after the registration work for one shutter is completed, there is no problem that the unique code signal for the next registration work is registered in the shutter that was previously registered. Excellent.
[0012]
Although the present invention is not limited to the first embodiment, the first transmitter 7a that first outputs a predetermined operation signal for additional registration of the unique code signal has the unique code signal already registered. If it is not done, it can be rejected. In that case, the control procedure may be set as shown in the flowchart of FIG. 3, and by doing so, additional registration can be made without your knowledge. Can be prevented.
