DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio remote control system, an antenna unit and an opening / closing body control unit for an opening / closing device for a building opening.
The present invention can be applied to wireless remote control systems (remote control systems) such as windows and overhead doors.

[0002]

2. Description of the Related Art There have been proposed many opening / closing devices for building openings in which opening / closing of an opening / closing member can be instructed using a remote control transmitter. For example, in a garage shutter, it is convenient that a user can open and close the shutter without getting off the vehicle, and a remote control system is often applied.

In such a remote control system for a shutter, a receiving antenna is mounted on a wall surface near the shutter or on a front surface or a lower surface of a storage box of the shutter by an antenna mounting tool, and a radio wave from a remote control transmitter is captured.

FIG. 6 is a block diagram showing a configuration of a conventional remote control system. An electric signal (for example, an ASK modulation signal or an FSK modulation signal) obtained by capturing and converting a radio wave from the remote control transmitter 10 by the reception antenna 11 extends from the base end of the reception antenna 11 and Is provided to the receiving unit 13 via a coaxial cable 12 of, for example, about 3 m to 8 m having a connector at its tip. Conventionally, the receiving antenna 11 and the coaxial cable 12 constitute an antenna unit.

[0005] The receiving unit 13 has a demodulation unit 14, a reception control unit 15, and a power supply unit 16. The power supply unit 16 forms an operating voltage supplied to the demodulation unit 14 and the reception control unit 15 from, for example, a commercial power supply. The electric signal from the receiving antenna 11 is input to the demodulation unit 14 in the receiving unit 13, and the original transmission signal (demodulated signal) obtained by demodulation by the demodulation unit 14 and transmitted by the remote control transmitter 10. Is given to the reception control unit 15. The reception control unit 15 decodes the demodulated signal, opens the shutter,
An open / close control signal for instructing closing or stopping is formed and supplied to a shutter control unit 18 via a cable 17 having connectors at both ends. Note that the reception control unit 15
If the demodulated signal includes the transmitter identification information, it is also checked whether or not the remote control transmitter 10 can issue an instruction for the shutter.

The shutter control unit 18 has a shutter control unit 19, a motor drive circuit 20, and a power supply unit 21. The power supply unit 21 forms an operating voltage to be supplied to the shutter control unit 19 and the motor drive circuit 20 from, for example, a commercial power supply. In the shutter control unit 18, the opening / closing control signal from the receiving unit 13 is given to a shutter control unit 19, and the shutter control unit 19
Based on the content (open, closed or stopped) of the opening / closing control signal, a motor drive signal for realizing opening, closing or stopping of the shutter is formed. Then, the motor drive circuit 20 causes a motor (not shown) to execute a desired operation (forward rotation, reverse rotation, rotation stop, etc.) according to the motor drive signal.

FIG. 7 shows the appearance and the like of each unit of the conventional remote control system having the above configuration.
In FIG. 7, the shutter control unit 18 is housed in an elongated casing 22 together with a motor and the like. The receiving unit 13 has a box shape as a single unit, and has a configuration in which the receiving unit 13 can be attached to a wall or the like near the shutter. Although omitted in FIG. 6, the receiving unit 13
A light-emitting element (LED) is provided for confirming any one of opening, closing, and stopping when instructed, and is generally installed outside a shutter storage box.
In this example, the receiving antenna 11 is a pole antenna.

Then, as described above, the receiving antenna 1
1 and the receiving unit 13 are connected by a coaxial cable 12, and the receiving unit 13 and the shutter control unit 18
The spaces are connected by a cable 17.

[0009]

However, the conventional remote control system has the following various problems.

As described above, in the case of the conventional remote control system, when the shutter control unit 18 is regarded as an element of the remote control system, the receiving antenna 11 and the receiving unit 13 are connected by the coaxial cable 12, and the receiving unit 13 and the shutter are connected. Cable 1 between control units 18
Since the connection is made at 7, the wiring work and the connector connection work take a considerable amount of time, and the cable laying amount becomes long when viewed from the whole remote control system.

Further, since a high-frequency signal in a radio frequency band before demodulation is simply transmitted between the receiving antenna 11 and the receiving unit 13 via the coaxial cable 12, the longer the coaxial cable 12 is, the more the receiving sensitivity (reception is possible). distance)
However, there was also a problem that it deteriorated.

Further, in the case of the conventional remote control system,
Since the receiving unit 13 and the shutter control unit 18 have the power supply units 16 and 21, respectively, it can be said that there is no use in terms of the entire system.

Some of the above-mentioned problems can be solved by fusing the receiving unit 13 and the shutter control unit 18.

However, in the case of the shutter, the operation signal from the opening / closing operation switch is basically provided to the shutter control unit 18 in a wired manner, and the remote control system is often provided as an option to add to or replace the shutter control unit. If the shutter control unit 18 and the shutter control unit 18 are formed in advance, if the remote control system is not applied, useless functions in the fusion unit will be excessive.

[0015] The various problems as described above occur not only for shutters but also for remote control systems for other building opening / closing devices such as doors, windows and overhead doors.

The present invention has been made in view of the above points, and has a construction time shorter than that of a conventional system, a simple system configuration, and a radio remote operation of a building opening / closing device capable of improving reception sensitivity. It is intended to provide a system. Another object of the present invention is to provide an antenna unit and an opening / closing body control unit suitable for such a system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) First Embodiment Hereinafter, a first embodiment in which a wireless remote control system, an antenna unit, and an opening / closing body control unit for a building opening / closing device according to the present invention are applied to a shutter remote control system. Will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of the remote control system according to the first embodiment, and FIG. 2 is a schematic perspective view showing the external configuration of the remote control system according to the first embodiment.

In FIG. 1, the remote control system according to the first embodiment includes a remote control transmitter 30, an antenna unit 3
1 and a shutter control unit 32.

The remote control transmitter 30 is the same as the conventional one, but in detail, the key operation unit 33, the transmission control unit 3
4, a modulation unit 35, a battery 36, and a transmission antenna 37.

The battery 36 supplies an operating voltage to the key operation unit 33, the transmission control unit 34, and the modulation unit 35. The key operation unit 33 provides an instruction signal for opening, closing, or stopping the shutter to the transmission control unit 34 according to a user operation. The transmission control section 34 receives an open, close, or stop instruction signal, assembles an original transmission signal (for example, serial transmission data), and provides the same to the modulation section 35. The transmission control unit 34 may, for example, repeat the unit transmission data connecting the transmitter identification data defining the remote control transmitter 30 and a data pattern indicating open, closed, or stopped multiple times (for example, five times). Form the transmission signal. Modulation unit 35
Is to modulate such an original transmission signal (transmission data) into a signal (radio transmission signal) in a radio frequency band (for example, 315 MHz) and radiate it from the transmission antenna 37 into space. The modulation unit 35 includes a band-pass filter and a power amplifier as necessary. Transmission antenna 3
7 is often provided inside a housing constituting the remote control transmitter 30.

Although the modulation scheme of the original transmission signal (transmission data) is arbitrary, for example, an ASK modulation scheme or an FSK modulation scheme can be applied.

The radiated radio wave (radio transmission signal) from the remote control transmitter 30 reaches the antenna unit 31.

The antenna unit 31 has an electrical configuration including a receiving antenna 38, a demodulation unit 39, and a light emitting element 40.
Consists of The receiving antenna 38 captures a radio wave radiated from the remote control transmitter 30 and converts it into an electric signal. The demodulation unit 39 demodulates the electric signal from the receiving antenna 38 to obtain an original transmission signal (demodulated signal) that the remote control transmitter 30 intends to transmit. The demodulated signal thus obtained is provided to the shutter control unit 32 via the demodulated signal transmission line 41a in the cable 41. The demodulation unit 39 monitors the presence of a valid radio wave from the remote control transmitter 30 based on the level of the demodulated signal (demodulated data). It is lit to notify the user that radio waves have been captured. Note that the light emitting element 40 may be omitted. Further, the demodulation unit 39 includes a band-pass filter that uses a radio frequency band as a pass band, a preamplifier, and a low-pass filter that uses a band of a demodulated signal as a pass band, as necessary.

Here, the antenna unit 31 does not include a power supply unit for obtaining an operating voltage from a commercial power supply or a battery for supplying the operating voltage, and the operating voltage necessary for processing by the demodulation unit 39 is controlled by the shutter control. It is supplied from the unit 32 side. The cable 41 connecting between the antenna unit 31 and the shutter control unit 32 is
An operation voltage supply line 41b is provided in addition to the demodulation signal transmission line 41a. An operation voltage used by the demodulation unit 39 is supplied from the shutter control unit 32 via the operation voltage supply line 41b. ing. The cable 41 is not shown in FIG. 1, but strictly includes an earth line, which defines a common ground potential for the demodulation signal transmission line 41a and the operating voltage supply line 41b. .

The external appearance of the antenna unit 31 is as shown in FIG. In the case of the first embodiment, the receiving antenna 38 is a pole antenna of, for example, about 20 cm, and a base end portion thereof is fixed to a mounting member 50 made of an insulator. The mounting member 50 is to be engaged with a mounting tool (not shown) provided on a wall surface near the shutter, for example. The mounting member 50 includes
A casing 51 having a width of about 2 cm, a height of about 5 cm, and a depth of about 1 cm is fixed. An electric circuit (for example, a printed circuit board) constituting the demodulation unit 39 is built in the housing 51, and the base end of the receiving antenna 38 is attached to a mounting member 50.
A lead member extending inward and extending laterally from a base end portion thereof is directly connected to an electric circuit (for example, a printed circuit board) constituting the demodulation section 39. Case 5
The cable 41 described above extends from the lower surface of the cable 1.

In the case of the first embodiment, the shutter control unit 32 has a control section 42, a motor drive circuit 43, and a power supply section 44. The power supply unit 44 forms an operating voltage to be supplied to the control unit 42 and the motor drive circuit 43 and an operating voltage to be supplied to the demodulation unit 39 in the antenna unit 31 from, for example, a commercial power supply.

In the shutter control unit 32, the demodulated signal (demodulated data) from the antenna unit 31 is
It is provided to the control unit 42. The control unit 42 decodes the demodulated data and checks whether the remote controller transmitter 30 of the transmission source can issue an instruction for the shutter. Then, the operation content of the instructed shutter, that is, opening of the shutter, A motor drive signal for realizing the opening, closing or stopping of the shutter is formed based on the recognition contents (opening, closing or stopping) while recognizing the closing or stopping. The motor drive circuit 43 causes a motor (not shown) to execute a desired operation (forward rotation, reverse rotation, rotation stop, etc.) according to the motor drive signal. Note that when the instruction content from the remote control transmitter 30 is inconsistent with the current shutter state (for example, when an opening operation is instructed in the shutter open state), the control unit 42 issues the instruction. Ignore the contents.

The function of the control unit 42 has been briefly described above in relation to the remote control system. However, detection processing such as position detection and obstacle detection during the operation of the shutter and processing corresponding thereto are naturally controlled. Things.

As is apparent from the above description, the control unit 42 of the first embodiment includes both the reception control unit 15 of the reception unit 13 and the shutter control unit 19 of the shutter control unit 18 in the above-described conventional remote control system. Is performed.

As shown in FIG. 2, the shutter control unit 32 of the first embodiment is also housed in an elongated casing 53 together with a motor and the like, as in the prior art.

In the remote control system according to the first embodiment having the above configuration, the user operates the remote control transmitter 30
When a key for instructing opening, closing, or stopping of the shutter in the key operation unit 33 is operated, a key operation signal is given from the key operation unit 33 to the transmission control unit 34 in accordance with a user operation. At this time, the transmission control unit 34 receives an open, close, or stop key operation signal, assembles an original transmission signal (for example, serial transmission data), and provides the same to the modulation unit 35.
Modulates such an original transmission signal into a signal in a radio frequency band (radio transmission signal) and radiates it from the transmission antenna 37 into space.

The radiated radio wave (radio transmission signal) from the remote control transmitter 30 is captured by the receiving antenna 38 and converted into an electric signal, and the electric signal is demodulated by the demodulation unit 39. The original transmission signal (demodulated signal) to be transmitted is demodulated. The demodulated signal thus obtained is provided to the shutter control unit 32 via the demodulated signal transmission line 41a in the cable 41.

In the shutter control unit 32,
The control unit 42 decodes the demodulated signal (demodulated data) from the antenna unit 31 and checks whether the remote control transmitter 30 of the transmission source can issue an instruction for the shutter. That is, it recognizes the opening, closing, or stopping of the shutter, and forms a motor drive signal for realizing the opening, closing, or stopping of the shutter based on the recognition content (open, closed, or stopped). Then, the motor drive circuit 43 causes a motor (not shown) to execute a desired operation (forward rotation, reverse rotation, rotation stop, etc.) according to the motor drive signal. As a result, the shutter opening / closing member performs the instructed operation, that is,
Open, close or stop.

According to the first embodiment, the demodulation unit 39
Is mounted on the antenna unit 31 and the antenna unit 3
1 through the cable 41, the shutter control unit 3
Since the configuration is such that the remote control system 2 is directly connected, only one cable is required for constructing the remote control system, and the wiring work and the connector connection work can be performed in a simple and short time. In addition, when viewed from the entire remote control system, the amount of cable laid can be reduced.

According to the first embodiment, since the electric signal itself in the radio frequency band does not flow through the cable, and the demodulated signal flows through the cable 41, the cable 41 between the antenna unit 31 and the shutter control unit 32 is not used.
, A sufficient reception sensitivity (receivable distance) can be secured.

Further, according to the first embodiment, since the operating voltage is supplied to the antenna unit 31 from the shutter control unit 32, only one power supply unit is required as a remote control system. The configuration when viewed as a whole can be simplified.

Furthermore, according to the first embodiment, since the antenna unit 31 is provided with the light-emitting element 40 which indicates that the radio wave from the remote control transmitter 30 has been captured,
The user can confirm that the remote control operation has been accepted. In addition, since the conventional receiving unit has a function of decoding the demodulated signal, the opening, stopping, and closing may be recognized and the corresponding light emitting element may be turned on. Since closing is an operation performed by the user, there is little need to make the information up to that point visible by lighting, and if the distance between the remote control transmitter and the receiving unit is long, any open, stop, or closed light emitting element It is not sufficient to check whether is turned on, but rather it is sufficient to visually recognize that the remote control operation has been accepted. (B) Second Embodiment Next, a second embodiment in which a wireless remote control system, an antenna unit, and an opening / closing body control unit for a building opening / closing device according to the present invention are applied to a shutter remote control system will be described with reference to the drawings. This will be described in detail with reference to FIG.

The remote control system according to the second embodiment can control the opening and closing of a plurality of shutters by one remote control transmitter. Here, FIG. 3 is a block diagram showing the configuration of the remote control system according to the second embodiment, in which the same and corresponding parts as those in FIG. 1 according to the first embodiment are denoted by the same reference numerals. Is shown.

The remote control transmitter 30 of the remote control system according to the second embodiment is not shown in detail (FIG. 1).
Key operation section 33, transmission control section 34, modulation section 3).
5, a battery 36 and a transmission antenna 37. However, the key operation unit 33 and the transmission control unit 34
Are slightly different from those of the first embodiment, and the differences will be described below.

In the case of the second embodiment, the key operation section 33 is also provided with a key for instructing a shutter whose operation is to be controlled. For example, it may be an individual key that specifies each shutter, or a key that indicates that a number input that specifies a shutter is followed by a numeric keypad. Also, a key may be included that indicates that operations for all shutters to be controlled are instructed simultaneously.

The transmission control section 34 of the second embodiment receives the shutter specification signal and the open, close or stop instruction signal, assembles an original transmission signal (serial transmission data), and provides the same to the modulation section 35. is there. Specifically, the transmission control unit 34 includes, for example, transmitter identification data that specifies the remote control transmitter 30 and data that specifies a shutter to be operation-controlled (may include data for all shutters). , An original transmission signal formed by connecting a plurality of (for example, five) unit transmission data connected to a data pattern representing open, closed, or stopped.

After such an original transmission signal is modulated by the modulator 35, it is radiated from the transmission antenna 37 into space.

In the second embodiment, the antenna unit 31 is the same as that of the first embodiment, and the detailed description is omitted.

In the second embodiment, shutter control units 32-1 and 32-2 corresponding to all N shutters 60-1, 60-2,.
.., 32-N. FIG. 3 shows two of them.
Only the shutter control units 32-1 and 32-2 are shown.

The connection between the antenna unit 31 and the N shutter control units 32-1 to 32-N is performed in terms of cables 41, 46-1,.
It is a connection (daisy-chain connection) via (N-1).

Each of the shutter control units 32-i (i is any one of 1 to N) has the same configuration. The shutter control unit 32-i of the second embodiment includes a control unit 42-i.
i, a demodulation signal transfer unit 45-i in addition to the motor drive circuit 43-i and the power supply unit 44-i.

The power supply 44-i is, for example, a commercial power supply.
It forms an operating voltage to be supplied to the control unit 42-i and the motor drive circuit 43-i. Also, the power supply unit 44-i
Is to form an operating voltage to be supplied to the immediately preceding antenna unit 31 or shutter control unit 32- (i-1) on any connection. In the antenna unit 31, the demodulation unit 39 uses the operating voltage from the power supply unit 44-1 as described above. In the shutter control unit 32- (i-1), the operating voltage from the power supply unit 44-i is used by the demodulation signal transfer unit 45-i.

In the shutter control unit 32-i, the input demodulated signal is supplied to the control unit 42-i and the demodulated signal transfer unit 45-i.

The control section 42-i is slightly different from the control section 42 of the first embodiment in the decoding processing of the demodulated signal. That is, in the case of the second embodiment, the demodulated signal includes not only the transmitter identification data that specifies the remote control transmitter 30 and the data that indicates opening, closing, or stopping, but also data that specifies the shutter to be operation-controlled. Therefore, the decoding process of the demodulated signal is different from that of the control unit 42 of the first embodiment.

The control section 42-i decodes the demodulated signal,
The remote control transmitter 30 of the transmission source operates the shutter 60-i.
Is confirmed, and whether the shutter whose operation is to be controlled is itself. When the data representing the shutter to be operation-controlled indicates all the shutters, it is recognized that the shutter to be operation-controlled is self.

When the source remote controller transmitter 30 cannot issue an instruction for the shutter 60-i,
Alternatively, when the shutter whose operation is to be controlled is not its own, the control unit 42-i does not send a motor drive signal to the motor drive circuit 43-i. On the other hand, when the remote control transmitter 30 of the transmission source can issue an instruction to the shutter 60-i and the shutter to be operation-controlled is itself, the control unit 42-i performs the operation of the instructed shutter. A motor drive circuit for recognizing the contents, that is, opening, closing or stopping of the shutter, and forming a motor driving signal for realizing opening, closing or stopping of the shutter based on the recognized contents (open, closed or stopped). 43-i
Give to.

Since the motor drive circuit 43-i is the same as that of the first embodiment, the description of its function is omitted.

The demodulated signal transfer section 45-i transfers the input demodulated signal to the next shutter control unit 32- (i + 1) on any connection. Here, as the demodulation signal transfer unit 45-i, for example, one that can realize electrical insulation using a photocoupler or the like is preferable. That is, since it is possible to prevent the adverse effect of the abnormality generated in the power supply unit in one of the shutter control units from being exerted on the other shutter control units, it is preferable to apply an electrically insulating configuration.

In the shutter control unit 32-N located last on any connection, the demodulated signal transfer section 4
Although 5-N is unnecessary, it is more practical to apply a shutter control unit 32-N similar to the others, rather than separately manufacturing a shutter control unit having no demodulation signal transfer unit.

In the remote control system according to the second embodiment having the above configuration, the user operates the remote control transmitter 30
When the key operation unit 33 is instructed to open, close, or stop the shutter 60-i, the transmission control unit 34 determines that the operation target shutter is the shutter 60-i, and that the operation content is open, closed, or stopped. That is, an original transmission signal (for example, serial transmission data) including data such as identification information of the remote control transmitter 30 is assembled and given to the modulation unit 35, and the modulation unit 35 transmits the original transmission signal (transmission data). The signal is modulated and converted into a signal in a radio frequency band (radio transmission signal), and emitted from the transmission antenna 37 into space.

The radiated radio wave (radio transmission signal) from the remote control transmitter 30 is captured by the receiving antenna 38 and converted into an electric signal, and the electric signal is demodulated by the demodulation unit 39 and transmitted to the remote controller. The original transmission signal (demodulated signal) that the device 30 attempts to transmit is demodulated.

The demodulated signal obtained in this manner is converted by the function of the demodulated signal transfer units 45-1 to 45- (N-1).
It is input to all shutter control units 32-1 to 32-N.

In the shutter control unit 32-i, when the control section 42-i decodes the demodulated signal, the control section 42-i recognizes that the instruction is directed to the self shutter 60-i (the remote control transmitter 30 as the transmission source transmits the shutter). To confirm that the shutter can be issued), and a motor drive that realizes opening, closing or stopping of the shutter based on the operation content of the designated shutter, that is, opening, closing or stopping of the shutter. Form a signal. And
The motor drive circuit 43-i causes a motor (not shown) to execute a desired operation (forward rotation, reverse rotation, rotation stop, etc.) according to the motor drive signal. As a result, the shutter opening / closing body performs the instructed operation, that is, opens, closes, or stops.

The other shutter control units 32-j (j
Are 1 to N, except for i).
Recognizes that it is not an instruction to the shutter 60-j when decoding the demodulated signal, and as a result, does not execute any shutter control processing.

According to the second embodiment, the demodulation unit 39
Is mounted on the antenna unit 31 and the antenna unit 3
1 through the cable 41, the shutter control unit 3
2-1, the number of required cables can be reduced by the omission of the conventional receiving unit.
Wiring work and connector connection work can be performed in a simple and short time, and the amount of cable laid can be reduced.

According to the second embodiment, the electric signal in the radio frequency band does not flow through the cable, and the demodulated signal flows through the cables 41, 46-1 to 46- (N-1). These cables 41, 46-1 to 46-
Even if (N-1) is slightly longer, a sufficient receiving sensitivity (receivable distance) can be secured.

Further, according to the second embodiment, the antenna unit 31 is configured to be supplied with the operating voltage from the shutter control unit 32-1. Therefore, the antenna unit 31 does not need a power supply unit. The number of power supply units required as a remote control system can be reduced, and the configuration as viewed as a whole system can be simplified.

Further, according to the second embodiment, 1
In a remote control system in which a plurality of remote control transmitters instruct a plurality of shutter operations, a demodulated signal is supplied to a plurality of connected shutter control units so that the operation of any one of the shutters can be controlled.
Compared with the function that a single remote control transmitter can instruct a plurality of shutter operations, the configuration of the entire remote control system can be made very simple.

For example, when one remote control transmitter intends to construct a remote control system instructing a plurality of shutter operations using a conventional receiving unit, the receiving unit has a function of decoding a demodulated signal. Have
A receiving unit for each shutter is required, and the configuration becomes complicated. Even if one receiving unit forms a signal to be supplied to the shutter control unit (such a system also constitutes another embodiment of the present invention), the conventional shutter control unit does not generate the open / close control signal. Since the configuration is in accordance with the input, the connection between the receiving unit and each shutter control unit is a star-like connection, and accordingly, the amount of laid cables is increased and the wiring work becomes complicated.

Further, according to the second embodiment,
Since the antenna unit 31 is provided with the light emitting element 40 that lights up to indicate that the radio wave from the remote control transmitter 30 has been captured, the user can confirm that the remote control operation has been accepted. (C) Third Embodiment Next, a third embodiment in which a wireless remote control system, an antenna unit, and an opening / closing body control unit for a building opening / closing device according to the present invention are applied to a shutter remote control system will be described with reference to the drawings. This will be described in detail with reference to FIG.

The remote control system according to the third embodiment has a plurality of receiving antennas for capturing radio waves from one remote control transmitter. Here, FIG.
