Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing instruction input device, for example, a shutter, a door, a window, an overhead door, a gate, a gate (a gate for a parking lot, etc.), a roll screen (for example, a light shielding film), a blind, and an awning device. The present invention can be applied to a wireless or wired remote control transmitter whose target is an instruction operation such as.

[0002]

2. Description of the Related Art Opening / closing control of an opening / closing body (If the opening / closing body has a locking / unlocking function, in addition to the opening / closing control, or instead of the opening / closing control, locking / unlocking control is also a term of the opening / closing control. A large number of opening / closing devices have been proposed in which a remote control transmitter can be used to instruct.

In a remote control system for a shutter, a remote control receiver for capturing and processing radio waves from a remote control transmitter is provided on the wall surface near the shutter, the surface of or inside a storage box of the shutter.

FIG. 16 is a block diagram showing the structure of a conventional remote control system. The electric signal obtained by capturing and converting the radio wave from the remote control transmitter 110 by the receiving antenna 111 is given to the receiving unit 113 via the coaxial cable 112, for example. In the reception unit 113, an electric signal from the reception antenna 111 side is demodulated by the demodulation unit 114, and the demodulation signal is decoded by the reception control unit 115 to form an opening / closing control signal for instructing opening / closing of the shutter. Via the cable 116,
It is provided to the shutter control unit 117.

In the shutter control unit 117, the shutter control section 118 determines whether the opening / closing control signal from the receiving unit 113 is open or closed.
A motor drive signal that realizes opening and closing of the shutter is formed, and the motor drive circuit 119 causes a motor (not shown) to perform a desired operation according to the motor drive signal.

By the way, as a remote control transmitter, a so-called three-point remote control transmitter having three operation keys for opening, stopping and closing is widely applied.

A so-called 1 having one operation key
There are also point remote control transmitters. For example, from the one-point remote control transmitter, only a signal indicating that it has been operated is transmitted to the remote control receiver. Remote control receiver is 1
Open every time a signal from the point remote control transmitter arrives
The operation of the shutter is cyclically controlled as follows: stop-close-open-stop-close -...

[0008]

In the case of the three-point remote control transmitter, the user can execute the intended shutter operation by operating the operation key for the intended shutter operation. However, since the remote control transmitter has operation keys for the number of types of shutter operation,
There is a limit to downsizing the remote control transmitter. For example, it is not preferable as a remote control transmitter when it is necessary to carry a plurality of remote control transmitters.

On the other hand, in the case of the one-point remote control transmitter, since the number of operation keys is one, it is expected that the remote control transmitter will be downsized. However, since the remote control receiver finally determines the operation content of the shutter, there is a possibility that a shutter operation different from the shutter operation intended by the user may be executed due to misunderstanding of the user.

Therefore, there is a demand for a small opening / closing instruction input device capable of sending a signal directly instructing the opening / closing body operation intended by the user.

[0011]

In order to solve such a problem, the present invention relates to an opening / closing instruction input device which outputs an operation instruction signal of an opening / closing body in response to an operation input by a user.
And an operation instruction signal forming means for forming and outputting, out of the plurality of operation instruction signals, an operation instruction signal of a type determined according to an operation change of the operation key. And

Here, it is preferable to further include an informing means for informing which kind of operation instruction signal can be generated in the current operation change of the operation key.

The operation change of the operation key is the operation time from the operation start time to the operation end time,
It is also preferable that the number of operations is within a predetermined time, and that the operation interval is from the first operation to the second operation.

Return to the standby state for key operation.

On the other hand, when the operation of the operation key 11C is not restored and the time measurement for the predetermined time Tc is completed, the control unit 12 returns to the above-mentioned step S48 and shifts to the confirmation processing whether the stop instruction is input. To do.

FIG. 14 is an explanatory diagram showing allocation of instructions from the time when the operation key 11C is operated. That is,
As the control unit 12 executes the processing shown in FIGS. 12 and 13, the types of instructions are time-divisionally allocated as shown in FIG.

Here, assuming that the time from the time when the operation key 11C is operated to the time when the operation is returned (released) is t, this operation time t defines the instruction content. Note that T in the following is Ta + Tb + Tc. Further, m is an integer of 0, 1, 2, ...

(A) When t ≦ Td: 1-point type instruction (b) Td + m × T <t ≦ Td + Tb + m × T 3-point type stop instruction (c) Td + Tb + m × T <t ≦ Td + Tb + Ta + m × T 3-point type instruction Open instruction (D) Td + Tb + Ta + m × T <t ≦ Td + Tb + Ta + Tc + m × T Three-point type close instruction For example, a user who prefers the one-point type operation key 11C
By operating the pressing time of only when the time is Td or less,
The operation of the shutter can be controlled by a one-point operation. Further, for example, a user who prefers the three-point type (a user who prefers an instruction clearly defining opening, stopping, and closing) turns on the light emitting element 15a, 15b, or 15c of the control operation that he or she desires. By releasing the depression of the operation key 11C at the time of opening, the operation of the shutter can be clearly controlled to open, stop, and close.

Next, the operation of the control unit 23 of the remote control receiver (20A) of the third embodiment will be described with reference to the flowchart of FIG.

When a radio reception signal of a predetermined level or higher is given from the reception antenna 21, the reception section 22 of the remote control receiver 20A demodulates the radio reception signal to obtain an original transmission signal (demodulation signal). It is given to the control unit 23.

The control unit 23 waits for the input of such an original transmission signal (demodulated signal) (S71). When the original transmission signal is input, the ID included in the signal is ID.
It is determined whether or not it matches the one registered in the memory 24, in other words, whether or not the remote control transmitter 10C of the transmission source can issue an instruction for the shutter (S72).

ID included in the input original transmission signal
If does not match the one registered in the ID memory 24, the control unit 23 ignores the original transmission signal input this time.

On the other hand, when the ID included in the original transmission signal is registered in the ID memory 24, the control unit 23
Decodes (determines) the content of the information inserted in the information part of the original transmission signal (S73).

When the information in the information section of the original transmission signal indicates the "opening operation", the control section 23 forms a shutter driving signal for instructing the opening operation to form the shutter driving section 40.
(S74), the immediately preceding operation information stored internally is updated to "open operation" (S75), and the state returns to the input waiting state of the original transmission signal.

Similarly, when the information in the information section of the original transmission signal indicates the "stop operation", the control section 23 forms a shutter drive signal instructing the stop operation and outputs it to the shutter drive section 40. (S76), immediately before operation information stored internally is updated to "stop operation" (S77), the state returns to the input waiting state of the original transmission signal, and the information in the information section of the input original transmission signal indicates "closing operation". When instructed, a shutter drive signal for instructing the closing operation is formed and output to the shutter drive unit 40 (S78), the immediately preceding operation information stored internally is updated to "closing operation" (S79), and the original transmission is performed. Return to the signal input waiting state.

On the other hand, when the information in the information section of the original transmission signal indicates the "motion cycle", the control section 23 recognizes the motion represented by the immediately previous motion information stored internally (S).
80), in the cyclic order of the operation, a shutter drive signal for instructing the next operation of the immediately previous operation is formed and output to the shutter drive unit 40 (S81), and the immediately previous operation information is updated to the instructed operation (S81). S82), and returns to the state of waiting for the input of the original transmission signal.

The third embodiment corresponds to the case where the cyclic order of the operation in the one-point type is open-stop-close-open-stop-close -... Therefore, if the immediately preceding operation recognized in step S80 is an "opening operation", a shutter drive signal for instructing a "stop operation" is formed in step S81, and if the immediately preceding operation recognized in step S80 is a "stop operation", a step is performed. In S81, a shutter drive signal for instructing "close operation" is formed. If the immediately previous operation recognized in step S80 is "close operation", a shutter drive signal for instructing "open operation" is formed in step S81.

(C-3) Effects of the Third Embodiment As described above, the same effects as those of the first embodiment can be obtained by the third embodiment.

Further, according to the third embodiment, the remote control transmitter 10C can be used as a one-point remote control transmitter, and the remote control transmitter 10C can be used as well.
It can also be used as a dot remote control transmitter, and can be used with higher versatility.

(D) Other Embodiments (D-1) In each of the above-mentioned embodiments, the shutter operation, which is meant at that time by the operation of one operation key, is made to be recognized by the user by using the light emitting element. However, instead of this or in addition to this, an audible notification means may be applied. Further, the visual notification means is not limited to the light emitting element, and may be a liquid crystal display or the like.

(D-2) In the first and third embodiments described above, the instruction to perform the operation represented by the character associated with the light emitting element which is lit when the key operation is stopped is shown. In the form, the operation for instructing the operation regulated by the number of key operations within the predetermined time is shown, but the instruction content from one operation key may be taken in by another method.

For example, it is assumed that the first key operation starts the time-division cyclic lighting of a plurality of light emitting elements, and the operation indicated by the character associated with the light emitting element that has been lighted at the second key operation is instructed. You may try to catch it. A so-called push-push type switch may be applied as the key in this case.

Further, for example, like Morse code, the change pattern in the operation time and the interval between the operations is made different for each shutter operation, and the instruction operation is recognized by the input change pattern. good.

(D-3) In the first and third embodiments described above, the operation time allocated to each operation is shown as being equally divided, but it may be unequal.

For example, the stop operation may be allocated twice as long as the time required for the opening operation or the closing operation. Stop action 2
It is also possible to allocate twice as much time as the stop operation by the cycle of T, the opening operation T, and the closing operation T, or by the cycle of the stopping operation T, the opening operation T, the stopping operation T, and the closing operation T. Alternatively, twice the time may be allocated to the stop operation.

Further, for example, the operation time may be allocated once for each operation, and the last allocation operation may be the allocation of time from the elapse of a predetermined time to infinity.
Note that the operation is always terminated, so infinity cannot be meaningful.

The operation for allocating the most time is not limited to the stop operation, and may be selected as appropriate according to the application of the remote control system.

Further, at the time of cyclic lighting of each light emitting element,
When switching the light emitting elements to be turned on, it is possible to provide a time during which all of a predetermined time (which may be a variable time) is off. Switching of shutter operation candidates becomes clear.

(D-4) In the second embodiment described above, the shutter operation of the instruction candidate is changed for each operation within a predetermined time, but the number of operations corresponding to each shutter operation is within the range. You may do it.

For example, one and two times are associated with the stopping operation, three and four times are associated with the opening operation, and five or more times are associated with the closing operation.

(D-5) In each of the embodiments described above, the one having the notifying means (light emitting element) for notifying which shutter operation can be instructed at this stage is shown, but the notifying means may be omitted. good.

For example, in the case where the motion type is defined by the number of operations per predetermined time, or when the motion type is defined by a pattern such as Morse code, the user does not need to be notified even if the notification means is omitted. , The intended operation can be easily instructed.

(D-6) In each of the above-described embodiments, the first motion candidate for a new operation is fixed regardless of the previous commanding motion, but the previous commanding motion is reflected. May be.

That is, each time the operation key 11C is operated, regardless of what the instruction operation was at the time of the previous return, the element that starts lighting (and after that) emits a predetermined light such as "stop". The light emitting element may be fixedly set to the element, or may be lit cyclically thereafter based on the light emitting element at the time of previous restoration (described in the expression of the first embodiment. Similar modifications can be given to the second and third embodiments).

In the former case, it is more effective if the instruction contents are set in the order of urgency, priority, or safety. From the viewpoint of higher safety, it is usually considered that the order is stop → open → close or open → stop → close.

In the latter case, from the viewpoint of operation, it is a method that can be adopted when there is not much difference in urgency level, priority level, safety level, etc. between the instruction contents, or even if there is no problem.

(D-7) In each of the above embodiments, the present invention is applied to the shutter remote control system. However, doors, windows, overhead doors, gates, gates (gates such as parking lots), roll screens, etc. It may be applied to a remote control system of an opening / closing device that generally controls the opening / closing body such as a light shielding film, a blind, an awning device.

(D-8) In each of the above embodiments, the present invention is applied to the remote control system for wireless communication for controlling the opening / closing body (shutter). However, a remote control transmitter and a remote control receiver are connected to each other. The present invention can be applied to a system connected by wire.
