Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system for a switching device, for example, a shutter, a door, a window, an overhead door, a gate, a gate (a gate of a parking lot, etc.), a roll screen (for example, a light shielding curtain), a blind, and an awning. Remote control system for equipment (remote control system)
It can be applied to such as.

[0002] The present invention also relates to a non-open / close body communication device as a component of such a communication system.

Further, the present invention relates to an opening / closing body side communication device as a component of such a communication system.

[0004]

2. Description of the Related Art Many opening / closing devices have been proposed in which opening and closing of an opening / closing member can be instructed by wireless communication 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 wireless remote control system is often applied.

In such a wireless remote control system for a shutter, a radio wave from a remote control transmitter is captured via a wireless transmission path by using a receiving antenna mounted on a wall near the shutter or on the front or lower surface of a storage box of the shutter. I do.

In a remote control receiver, an electric signal (for example, an ASK modulation signal or an FSK modulation signal) captured and converted by a reception antenna is demodulated by a reception section, and an original transmission signal (a transmission signal) transmitted by the remote control transmitter is transmitted. The demodulated signal is provided to the reception control unit. Then, the original transmission signal is decoded by the reception control unit, and based on the identification information (hereinafter abbreviated as ID) inserted into the signal, the remote control transmitter that is the source of the original transmission signal is transmitted to the remote control receiver. It confirms that the operation instruction can be issued to the user (ID verification), and then, based on the information content inserted in the original transmission signal, operates the shutter (open operation, close operation or stop operation). , Etc.) and supplies it to the shutter controller SC (see FIG. 3).

The shutter control unit SC controls the operation of the motor for operating the shutter, thereby realizing the shutter operation intended by the operator (user) of the remote control transmitter.

On the other hand, there is also an opening / closing device for instructing opening / closing of an opening / closing body by wired communication.

In the case of a wired remote control system in which such wired communication is applied to the garage shutter, the remote control receiver receives the electric signal via a wired transmission path.

[0010]

By the way, in the above-mentioned wireless remote control system, the distance between the receiving antenna and the remote control transmitter is within the range of the maximum communicable distance determined by various conditions such as the transmission power of the remote control transmitter. Wherever the remote control transmitter is located, the shutter can be operated in any posture, and there is a great advantage that it is very convenient for the user, but the shutter operation is used as a communication path. There is also a drawback that the reliability is easily affected by the condition of the wireless transmission path, which is not always high.

For example, if the state of the wireless transmission path is deteriorated due to interference due to unexpected interference with the same frequency as the transmission frequency of the remote control transmitter, the maximum communicable distance is reduced, and the user operating the remote control transmitter is operated. The possibility that the shutter operation is not performed as intended is increased, and the reliability is reduced.

[0012] When the jamming radio wave is not so strong, the remote control transmitter is brought close to the receiving antenna, and within the maximum communicable distance at that time, a normal shutter operation intended by the user is performed. However, when the jamming radio wave is strong, the maximum communicable distance may be zero or close to zero, which is also difficult. Further, since the magnitude of the transmission power of the remote control transmitter is specified by the radio law, it is not possible to increase the transmission power beyond the specification.

[0013] It is difficult to determine the mechanism of generation of radio waves and the source of the radio waves, and even if it is possible, it is practically difficult to take countermeasures. Many.

On the other hand, in the case of the above-described wired remote control system, there is almost no possibility that the state of the wired transmission path is deteriorated by such unexpected interference waves, and the reliability of the communication path is high. Although the state of the wired transmission path may be deteriorated due to unnecessary radiation or the like, in many cases, the generation source is located inside the wired remote control system, is predictable, and it is easy to take countermeasures.

[0015] However, this wired remote control system is not related to the ease of use that the wireless remote control system has, and the user always operates the fixed operation unit (the remote control of the wireless remote control system) fixedly mounted at a predetermined place. The shutter operation can be performed only by moving to a position of an operation panel equipped with a function corresponding to a transmitter and operating a button, for example, of the fixed operation unit.

On the other hand, an actual remote control system is often a mixed system in which the features of the wireless remote control system and the wired remote control system are mixed.

In the case of the mixed system, the user can perform a shutter operation by wireless communication using a remote control transmitter as in the wireless remote control system, and can operate a fixed operation unit as in the wired remote control system. The shutter operation can be performed by communication.

However, in the mixed system, since the remote control transmitter is very easy to use as described above, it is assumed that wireless communication is practically used in most cases, and wired communication is regarded as emergency use. ,
It is considered that they are not always arranged in such a manner as to enable quick operation by the user.

If the fixed operation section is arranged, for example, in the vicinity of the motor and the shutter control section SC, the signal line connecting the fixed operation section and the shutter control section SC can be shortened.
The troublesome mounting work can be omitted. The installation place of the fixed operation unit that satisfies such conditions is a shutter storage box in which the motor and the shutter control unit SC are mounted. The shutter storage box is a storage body for storing the shutter wound by using the driving force of the motor, and is usually provided at a position higher than the ground by about 3 m.

Although the mixing system having such a configuration is efficient in a sense, the maximum communicable distance is close to zero, and when the user operates the fixed operation section, the usability is very poor. There is.

Further, providing a fixed operation unit having a function almost completely overlapping with that of the remote control transmitter separately from the remote control transmitter is not efficient in terms of hardware scale, and causes a cost increase.

The above-mentioned problems are common not only to shutters but also to remote control systems for other opening / closing devices such as doors, windows, and overhead doors.

An object of the present invention is to provide a communication system for a switchgear having both ease of use of a wireless remote control system and high reliability of a wired remote control system.

Another object of the present invention is to provide a non-opening / closing body side communication device and an opening / closing body side communication device as components of such a communication system.

[0025]

In order to solve this problem, a non-opening / closing body side communication device of the present invention communicates a transmission signal with an opening / closing body side communication device arranged on the opening / closing body side. In the device, a non-opening / closing body side wireless communication means for communicating the transmission signal via a predetermined wireless transmission path in at least one direction with the opening / closing body communication device, and a predetermined wired transmission in at least one direction. And a non-opening / closing body side wired communication means for communicating the transmission signal via a road.

Further, in the opening / closing body side communication device of the present invention, the opening / closing body side communication device which is disposed on the opening / closing body side and communicates a transmission signal with the non-opening / closing body side communication device. An opening / closing body-side wireless communication unit that communicates the transmission signal via a predetermined wireless transmission path in at least one direction, and an opening / closing body side that communicates the transmission signal via a predetermined wired transmission path in at least one direction. Wire communication means.

Further, a communication system for an opening / closing device according to the present invention comprises:
It is characterized by being constituted by the open / close body communication device according to any one of claims 4 to 6.

[0028]

BEST MODE FOR CARRYING OUT THE INVENTION (A) Embodiment Hereinafter, a remote control system for a switching device, a remote control transmitter and a remote control receiver according to the present invention will be described with reference to the above description for a garage shutter using a coaxial cable as a wired transmission path. The first embodiment will be described by taking a case where the present invention is applied to a mixing system as an example.

A high-frequency signal having the same frequency as that transmitted to the wireless transmission path is transmitted to the coaxial cable as the transmission signal.

The following first and second embodiments have functions corresponding to two modes, a wireless communication mode for performing wireless communication and a wired communication mode for performing wired communication.

(A-1) Configuration of the First Embodiment FIG. 2 shows the overall configuration of a garage shutter mixing system (wired / wireless mixing system) 40.

In FIG. 2, the mixing system 40 comprises
A remote control transmitter 10, a remote control receiver 20, and a slot unit 30 are provided.

The radio signal LS1 transmitted from the remote control transmitter 10 is used in the radio communication mode, propagates through a space 42 which is a radio transmission path (WL1), and is received by the remote control receiver 20 as a radio signal LS2. You.

The slot 30 and the remote control receiver 2
0 is a coaxial cable 41 which is a wired transmission path (WW1).
Connected through. Here, the remote control receiver 20
Following the example of the installation location of the fixed operation unit of the mixing system described in the section of the problem to be solved by the invention, the installation location is a shutter storage box equipped with the motor and the shutter control unit SC. I do.

In general, a coaxial cable exhibits a strong balance to high-frequency transmission, functions as a high-quality transmission line resistant to noise, and has a characteristic that a transmission signal has a small attenuation.

The mixing system 40 of the present embodiment is
The remote control transmitter 10 does not have the fixed operation unit.
However, it also functions as a normal remote control transmitter, and also functions as a fixed operation unit when the maximum communicable distance approaches zero.

However, in order to cope with an extremely rare case where the remote control transmitter 10 is lost or breaks down, the fixed operation section may be provided.

The installation location of the slot section 30 is set at an outer wall near the garage (for example, a height of 1.5 m from the ground) so that the user can easily mount the remote control transmitter 10.
Or a guide rail for defining the operation trajectory of the shutter. When installing on a guide rail, installation work is not required since it is already installed at the time of factory shipment.

The radio signal LS2 received by the remote control receiver 20 from the space 42 is based on the distance between the remote control transmitter 10 and the remote control receiver 20 (strictly speaking, the remote control transmitter 1).
0 is shorter than the maximum communicable distance).
The signal is substantially the same as the radio signal LS1 and has a sufficiently high quality. However, when the signal is long, the degree of deterioration is remarkable, and a signal different from the signal LS1 cannot be expected and normal communication cannot be expected.

The maximum value of the maximum communicable distance is, for example, about 30 m. The maximum value is shown when the state of the space 42 as the wireless transmission path is good. When a building exists between the remote control transmitter 10 and the remote control receiver 20, or when the above-described interference due to the interfering radio waves occurs, the state of the space 42 as the wireless transmission path deteriorates, and the maximum communication is possible. The distance becomes shorter.

Even if no jamming radio wave or building exists, for example, when the receiving antenna 21A is damaged, the maximum communicable distance is reduced.

Therefore, it is necessary to assume 0 m as the minimum value of the maximum communicable distance.

The frequency of the radio signal LS1 wirelessly transmitted by the remote control transmitter 10 is about 300 MHz (for example, 315 MHz) or about 400 MHz (for example, 426 MHz).
MHz).

Next, the internal configuration of the remote control transmitter 10 will be described. The internal configuration of the remote control transmitter 10 is as shown in FIG. If the remote control transmitter 10 is configured to have a palm size that is compact enough to fit in the palm of the user's hand, the degree of freedom of the user's posture when operating the remote control transmitter 10 can be increased, and operability can also be improved.

(A-1-1) Internal Configuration of Remote Control Transmitter In FIG.
And a wired transmission unit 12, a signal generation unit 13, a processor 14, a mode switching unit 15, a mounting detection unit 16, an input operation unit 17, and a memory 18.

The wireless transmission section 11 includes an antenna unit for wireless transmission, filter means, necessary RF (high frequency) amplification means, and the like.

In general, it is considered that the antenna unit of the remote control transmitter 10 is not in a form protruding outside the remote control transmitter 10 but in a form of a built-in antenna, because it is convenient for the user and is preferable.

Also in the present embodiment, as shown by the broken line in FIG. 4, the entire radio transmission section 11 is housed inside the remote control transmitter 10, and the antenna unit is a built-in antenna.

The wire transmission section 12 includes a connector having the female contact CF shown in FIG. This female contact CF is indicated by a chain line CH1 in FIG.
When the remote control transmitter 10 is mounted in the slot 30 according to (1), it is a portion that fits and contacts the male contact CM formed on the slot 30 side to form the wired transmission path WW1 together with the coaxial cable 41. .

The male and female contacts of the contacts CF and CM can be exchanged. However, since the remote controller 10 is held by the user and operated, the structure in which the male contacts protrude from the outer surface of the remote controller 10 is as follows. In this respect, a structure that does not protrude is more preferable because it may hinder the user.

The wired signal W transmitted from the wired transmitting unit 12
S1 is used in the wired communication mode. The wired signal WS1 is the same high-frequency signal as the wireless signal LS1 transmitted from the wireless transmission unit 11, but the wireless signal L
In order to occupy a band other than a predetermined frequency (for example, 315 MHz) so as not to violate the radio law, it is indispensable for S1 to limit the band using the filter means. In that case it is not necessary. However, even in the case of the wired transmission unit 12, there is an advantage in that unnecessary bands are limited so as to conform to processing on the remote control receiver 20 side and transmission characteristics of the coaxial cable 41.

Regarding the transmission power, in the case of the wireless transmission unit 11, it is preferable to use the maximum power allowed by the radio law in order to increase the maximum communicable distance. The length of the coaxial cable 41, which is the wired transmission path WW1, is usually about several meters, and it is considered that a very large transmission power is not required.

The wired signal WS1 of the coaxial cable 41
Is small, which also contributes to a decrease in the transmission power. Therefore, when the wired transmission unit 12 is operated by electric power from a battery, the life of the battery can be extended.

The wired transmission section 12 needs to be equipped with a balanced driver to drive the coaxial cable 41 which is a balanced transmission path.

The signal generator 13 includes an encoder and a modulator, and the control signal P supplied from the processor 14 is provided.
This section generates and outputs a generation signal L1 or W1 including a predetermined operation state instruction signal for instructing a shutter operation according to C1. L1 is a generated signal supplied to the wireless transmission unit 11, and W1 is a generated signal supplied to the wired transmission unit 12.

In the present embodiment, in both the wired communication mode and the wireless communication mode, since the generated signals L1 and W1 having the same specifications such as the frequency, the modulation method, and the encoding method are used, the signal generation unit 13 and its peripheral circuits are used. And the circuit scale can be reduced.

The modulation method of the modulation section may be the above-described ASK modulation signal, FSK modulation signal, or the like.

Each of the generation signals L1 or W1 needs to designate at least three types of shutter operations, ie, an opening operation, a closing operation, and a stopping operation, and a partial opening operation indicating a partial opening of a shutter is specified from the beginning. In the case of a system configuration that can be used, it is necessary to specify four types. If the contents of the operation state instruction signal are these four types, the main body of the generation signal L1 or W1 (that is, the operation state instruction signal) needs only 2 bits, and even if encoding is considered, these 2 bits are several times larger. It only results in a number of bits.

The processor 14 outputs a control signal PC2 in addition to the control signal PC1.

The input to the processor 14 includes an operation signal M1 supplied from the input operation unit 17 and a mounting detection unit 16
Is an attachment detection signal AD1 supplied from the controller. The processor 14 reads and writes a program code and a data code from and to the memory 18 according to the contents of the operation signal M1 and the attachment detection signal AD1, and changes the contents of the control signals PC1 and PC2 according to the code.

The input operation unit 17 includes operation keys 17A to 17C shown in FIG. 4 and a signal generation unit for generating the operation signal M1 according to the operation state and operation order of the operation keys 17A to 17C. Is provided.

Note that the number of operation keys may be more or less than three as required. However, increasing the number of keys is disadvantageous in terms of cost and downsizing of the body of the remote control transmitter 10, and conversely, decreasing the number of keys is generally associated with a necessary shutter operation (for example, the above-mentioned four types). This operation means that the order of key operations for performing the above operation becomes complicated, and therefore, it is generally considered that about three described here are appropriate.

The mounting detecting section 16 is a part for electrically detecting that the male contact CM has been inserted and fitted into the female contact CF (the mounting completed state).

Such detection is performed, for example, by using a TTL (transistor transistor logic) gate or a CMOS.
(Complementary MOS) gate. In this case, the input pin of the gate is pulled up or pulled down inside the mounting detection unit 16 and a circuit configuration is set such that the potential of the input pin drops or rises due to a voltage drop at the time of fitting. Malfunction due to extraneous noise can be prevented, and the gate itself can be protected from destruction.

If it is not desired to provide a power supply for the detection on the slot section 30 side, the pull-up will be adopted. In this case, due to the fitting, the current flowing out of the power supply voltage in the attachment detection unit 16 flows to the ground on the slot unit 30 side via the pull-up resistor in the attachment detection unit 16 and is connected to the pull-up resistor. The potential of the input pin thus set will drop due to the voltage drop.

The detection mechanism of the mounting detection unit 16 is not limited to such an electrical detection. For example, first, the mounting is detected by a mechanical change, and the mechanical change is converted into an electrical change. It is also possible to adopt a configuration for conversion.

As an example, a projection is formed on the slot portion 30 side, and when the mounting is performed normally, the projection pushes a push button switch formed on the remote control transmitter 10 side. It is also conceivable to keep it.

Of course, instead of automatically detecting the mounting, the user consciously performs a button operation (for example, operation of the operation keys 17A to 17C) and informs the processor 14 of the mounting. Such a configuration is also possible.

In short, between the remote control transmitter 10 and the remote control receiver 20, a wired transmission path can be reliably connected when necessary, and the wired transmission path can be disconnected when unnecessary. Any configuration may be used.

In any case, when the mounting detector 16 detects the mounting (mounting completed state) and outputs the mounting detection signal AD1, the processor 14 changes the state of the control signal PC2 accordingly. Will be. Therefore, there are two states of the control signal PC2: a state indicating mounting and a state indicating non-mounting.

When the control signal PC2 indicates a non-attachment state, the mode switching section 15 enables the mode signal MD1 and invalidates the mode signal MD2. On the other hand, when the control signal PC2 indicates the mounting, the mode signal MD1 is made invalid and the mode signal MD2 is made valid.

Since only the transmitting section 11 or 12 receiving the valid mode signal MD1 or MD2 operates effectively, only one of the wireless transmitting section 11 and the wired transmitting section 12 is always valid in the present embodiment. The other is in an invalid state.

As described above, the configuration which is made valid alternatively is to transmit the wired signal WS1 during wireless communication using the wireless transmission line WL1 and to use the wired transmission line WW1. This is because transmitting the wireless signal LS1 while performing wired communication is useless because power is consumed unnecessarily.

Further, in the present embodiment, not only is it wasteful, but also in this embodiment, since the wired signal WS1 is a high-frequency signal having the same frequency as the radio signal LS1, a member not intended as an antenna, such as a female contact CF, is used. It may function as a transmitting antenna. In that case, the possibility that the signal (wireless signal WS1 or wireless signal LS1) not to be used for communication becomes an interference wave with respect to the signal (wireless signal LS1 or wired signal WS1) that is desired to be used for communication. Can not be denied, it can be said that it is better to activate the transmission unit 11 or 12 alternatively.

If the alternative activation is not performed, a problem may occur when the wired communication mode is started because the maximum communicable distance is extremely short due to strong jamming radio waves. This is because, depending on the circuit configuration and the mounting state in the vicinity of the later-described reception processing unit 23 (see FIG. 3) inside the remote control receiver 20, unless it is selectively activated as described above, the signal is normally received by wired communication. This is because the quality of the generated signal (W2) may be deteriorated inside the remote control receiver 20 due to the interference of the interfering radio wave (L2) received by the wireless communication.

However, if the influence of these interferences can be suppressed to a practically sufficient degree, the mode switching unit 15 is omitted and both the transmission units 11 and 12 always operate. A configuration in which a signal is transmitted is also possible. In that case, the mounting detection unit 16 can also be omitted, and the configuration of the remote control transmitter 10 can be greatly simplified.

Next, the configuration of the slot section 30 for receiving the above-described mounting of the remote control transmitter 10 will be described.

(A-1-2) Configuration of Slot Portion As is apparent from FIG. 4, the entire slot portion 30 has a substantially "concave" shape, and one horizontal member extending in the horizontal direction. 33, and two vertical members 31 and 32 extending vertically upward from both ends of the horizontal member 33.

The two vertical members 31 and 32 have symmetrical shapes, and have mounting grooves 31A and 32A, respectively.

When the remote control transmitter 10 is slid along the dashed line CH1 from the direction of the arrow D1, the mounting groove 32
In A, the mounting edge 10B of the remote control transmitter 10 is indicated by an arrow D1.
In the mounting groove 31A, the mounting edge 10A of the remote control transmitter 10 moves in the direction of the arrow D1, and finally the mounting is completed in which the male contact CM is fitted to the female contact CF. The structure is such that the movement stops.

In this mounting completed state, the remote control transmitter 1
0 is held and fixed in the slot 30 by the action of the two mounting grooves 31A and 32A, the horizontal member 33, and gravity.

The back surface 30B of the slot portion 30 is a surface which is brought into close contact with the guide rail and the outer wall surface near the garage by the above-mentioned installation and mounting work, and the opposite surface 30A is used to operate the operation keys 17A to 17C of the remote control transmitter 10. This is a surface located closer to the user who operates.

In the mounting completed state, the operation keys 17
A to 17C are between the two vertical members 31, 32,
Since the user is exposed to the user, the user can easily operate these operation keys.

The configuration of the slot portion 30 shown in FIG. 4 is merely an example. For example, a configuration in which the slot portion 30 is slid from the horizontal direction, or a configuration in which the slot portion 30 is mounted in a direction perpendicular to the outer wall surface is also considered. Alternatively, a configuration in which the remote control transmitter 10 is held by a mechanical movable mechanism is also possible.

However, in any case, it is necessary to consider that the user can easily operate the operation keys (17A and the like) in the mounting completed state.

For example, the shape of the remote control transmitter 10 is shown in FIG.
In the case of a non-card type as shown in FIG.
When the shape or arrangement of the slot portion 30 is changed from the state shown in FIG. 4, the shape of the slot portion 30 needs to be changed correspondingly.

Finally, the internal configuration of the remote control receiver 20 connected to such a slot section 30 via a coaxial cable 41 will be described. The internal configuration of the remote control receiver 20 is as shown in FIG.

(A-1-3) Internal Configuration of Remote Control Receiver In FIG.
, A wired reception unit 22, a reception processing unit 23, a processor 24, a mode switching unit 25, a mounting detection unit 26, and a memory 28.

The functions of the components with the reference numerals corresponding to the components of the remote control transmitter 10 correspond to the functions of the components of the remote control transmitter 10.

That is, the wireless receiving section 21 corresponds to the wireless transmitting section 11, and the wired receiving section 22 corresponds to the wired receiving section 12.
, A reception processing unit 23 corresponds to the signal generation unit 13, a processor 24 corresponds to the processor 14, a mode switching unit 25 corresponds to the mode switching unit 15, and a mounting detection unit 26 corresponds to the mounting detection The memory 28 corresponding to the unit 16
Corresponds to the memory 18.

Therefore, the function of each signal in the remote control receiver 20 also corresponds to each signal in the remote control transmitter 10 with the corresponding symbol.

That is, the generation signal L2 is equal to the generation signal L
1, the generation signal W2 corresponds to the generation signal W1, the mode signal MD3 corresponds to the mode signal MD1, the mode signal MD4 corresponds to the mode signal MD2, and the control signal PC4 corresponds to the control signal PC2. Correspondingly, the mounting detection signal AD2 corresponds to the mounting detection signal AD1.

However, unlike the remote control transmitter 10, the remote control receiver 20 is not a device directly related to the usability and operability of the user, and therefore does not need to be configured as compact as the remote control transmitter 10.

Therefore, the antenna unit provided in radio receiving section 21 does not necessarily need to be a built-in antenna like the transmitting antenna of remote control transmitter 10.
Rather, in order to secure a sufficiently high antenna gain and extend the maximum communicable distance, it is preferable to use the external antenna 21 </ b> A that protrudes outside the remote control receiver 20.

Further, since this apparatus is a remote control receiver, there is no component corresponding to the input operation unit 17 unlike the remote control transmitter 10, and there is no signal corresponding to the control signal PC1.

Since there is no signal corresponding to the control signal PC1, the reception processing section 23 outputs the generated signal L
It only needs to demodulate and decode 2 or W2 and supply a decoded signal (opening / closing control signal) SCS obtained as a result of the decoding to a shutter control unit SC that controls the motor. Therefore, the reception processing unit 23 includes a decoding unit and a demodulation unit.

The receiver mounted on the wired receiver 22 must be a balanced receiver corresponding to the coaxial cable 41 which is a balanced transmission line.

The mounting detecting section 26 does not directly detect the mounting of the remote control transmitter 10 into the slot section 30 as in the mounting detecting section 16 but directly detects the mounting of the remote controlling transmitter 10. In a case where the attachment detection signal AD1 is output by the attachment detection of the attachment 16, the attachment is detected by indirectly recognizing the attachment detection signal AD1. Therefore, on the remote control transmitter 10 side, the processor 14 is included in the generated signal L1 or W1.
Needs to include the mounting information IA indicating that the mounting detection signal AD1 has been supplied. This is also performed using the control signal PC1.

That is, the attachment detection unit 26 outputs the decoded signal SC
By detecting the mounting information IA in S, the mounting is indirectly detected, and a mounting detection signal AD2 is supplied to the processor 24. The mounting information IA is
Since the signal is the source of the control signal PC4 for controlling the mode switching unit 25, the remote control transmitter 10 operates the operation key 17A
It is more efficient to transmit the mounting information IA before starting to transmit the original operation state instruction signal corresponding to the operation of ~ 17C.

If this procedure is not followed, the wired signal WS1 will be supplied to the invalid wired transmission unit 22, and the user operates the operation keys 17A to 17C again after transmitting the mounting information IA. The burden of doing so.

Normally, however, it is considered that the user operates the operation keys 17A to 17C after the above-mentioned mounting completion state is reached. Therefore, when the mounting completion state is reached and the mounting detection signal AD1 is supplied, the control signal is output. If the mode switching (wireless communication mode → wired communication mode) is performed by the PC 2 and the mounting information IA is immediately transmitted as the generation signal W1, the above procedure will be followed. In this case, the processor 14 waits for the operation signal M1 after transmitting the mounting information IA.

Further, the mounting detecting section 26 is
6, it is also possible to adopt a configuration in which the mounting is directly detected. In that case, however, a wired transmission for transmitting the wired signal WS1 between the slot unit 30 and the remote control receiver 20 is performed. It is considered that it is necessary to provide a transmission path for attachment detection independent of the path, which causes an increase in cost and a decrease in workability.

Hereinafter, the operation of the present embodiment having the above configuration will be described.

(A-2) Operation of First Embodiment In FIG. 2, the mixing system 40 is normally used in a convenient radio communication mode.

In the wireless communication mode, the remote control transmitter 10
Wirelessly transmits the wireless signal LS1. When the maximum communicable distance is 30 m, if the distance to the remote control receiver 20 is within 30 m, a high-quality wireless signal LS2 is received by the remote control receiver 20, and according to the operation of the operation keys 17A to 17C, The normal shutter operation as intended by the user is performed. In this wireless communication mode, the remote control transmitter 10 may be held by the user with his / her hand,
It may be fixed to a car or the like.

If the maximum communicable distance becomes shorter than the above 30 m and becomes, for example, about 10 m due to the factors such as the above-mentioned jamming radio waves, the user moves closer to the remote control receiver 20 within the above 10 m and the normal shutter is released. Actions can be taken.

When the maximum communicable distance is about several meters or more,
The user can use the wireless communication mode,
Usually, it is considered more convenient to use the wireless communication mode than the wired communication mode.

However, when the jamming radio wave is extremely strong, the maximum communicable distance becomes extremely short, and 0 m
It can happen to be close to

In such a case, since it is almost impossible to use the wireless communication mode, the user needs to set the remote control transmitter 10 in FIG.
Is attached to the slot 33 in accordance with the alternate long and short dash line CH1 shown in FIG.

When the mounting is completed, the mounting detection signal AD1 is supplied to the processor 14, and the mode is automatically switched in the remote control transmitter 10. First, the mounting information IA is transmitted as the generation signal W1. You. By receiving the mounting information IA, the mode switching corresponding to the transmitter 10 is also performed on the remote control receiver 20 side, and the wired communication mode can be used.

As described above, the coaxial cable 41 is a high-quality transmission line that exhibits a strong balance with the wired signal WS1, which is a high-frequency signal. The signal W2 is transmitted to the reception processing unit 23
Can be supplied to

That is, the external jamming radio wave acts on the coaxial cable 41 as common mode noise.
The balance of the coaxial cable 41 prevents the common mode noise from changing to the normal mode noise, so that it is easy to eliminate the influence of the noise, and good wired communication is ensured.

When the factor that extremely shortened the maximum communicable distance is other than the jamming radio waves, for example, when the above-mentioned building is present or the receiving antenna 21A is damaged, even the normal mode noise gets on the coaxial cable 41. Since there is no possibility, it is clear that good wired communication can be ensured.

From this, even if the wired transmission line (the coaxial cable 41 in this case) is unbalanced, it can sufficiently cope with factors such as the presence of a building and breakage of the receiving antenna 21A. You can say that.

Therefore, if a mixed system that is not affected by extremely strong jamming waves or a mixed system that may be affected by extremely strong jamming waves but does not need to cope with it is assumed, It is also possible to use an unbalanced transmission line as the transmission line. Making the wired transmission line a balanced type means that the drivers and receivers in the wired transmitting unit 12 and the wired receiving unit 22 are also of a balanced type. Also, the receiver can be made unbalanced to reduce the circuit scale and cost. The transmission path itself,
An unbalanced transmission line can be configured at lower cost than a coaxial cable.

(A-3) Effects of the First Embodiment As described above, according to the present embodiment, the same ease of use as in the conventional wireless communication can be ensured in the wireless communication mode, and the wireless communication mode can be used in the wired communication mode. The usability is also better than before.

In the present embodiment, the same remote control transmitter can be used in both the wireless communication mode and the wired communication mode. Therefore, it is not necessary to provide the above-mentioned fixed operation unit separately from the remote control transmitter. It is possible to reduce the size of the wear and reduce the cost.

Further, the signal generation unit (13), the processors (14, 24), and the input operation unit (1
7) Since the reception processing unit (23) can use the components of the conventional remote control transmitter and the remote control receiver, the conventional circuit configuration (LSI (large-scale integrated circuit) or the like) can be used as it is. Is also possible, which is superior in terms of feasibility and cost.

(B) Second Embodiment In the following, only differences between the present embodiment and the first embodiment will be described.

In the present embodiment, a twisted pair cable (twisted pair: a type of two-wire cable) 71 is used as the wire transmission line WW1 instead of the coaxial cable 41 of the first embodiment.

(B-1) Configuration and Operation of Second Embodiment As shown in FIG. 2, the mixing system 70 of the present embodiment has the same overall configuration as the mixing system 40 of the first embodiment. Is a twisted pair cable 7 as a wired transmission path.
1, and the low-frequency wired signal W is used for the twisted pair cable 71 instead of the high frequency as in the first embodiment.
S2 is transmitted. A coaxial cable cannot be used in the present embodiment because it exhibits an imbalance in transmitting low-frequency signals.

Generally, a twisted pair cable is a cable having a sufficiently high degree of balance. Since the two parallel signal lines arranged in close contact with each other have considerably high balance, it is possible to replace the twisted pair cable 71 with an untwisted (untwisted) pair cable (that is, a non-twisted pair wire). Although there is a balance, twisted pair cables are better. Therefore, in order to improve the noise resistance, it is better to use a twisted pair cable.

However, the wired transmission path WW of this embodiment
Since the length of 1 is usually considered to be within about several meters, even if a pair cable having a lower balance than a twisted pair cable is used, there is a possibility that sufficiently good characteristics can be obtained in practical use. high.

Further, as shown in FIG. 1, the overall configuration of the remote control transmitter 50 of the present embodiment is the same as that of the remote control transmitter 10 of the first embodiment, but the function of the signal generation unit 53 is the same as that of the first embodiment. This is different from the signal generation unit 13 of the first embodiment. This is a difference related to the fact that the wired signal WS2 used in the present embodiment is a low-frequency signal.

In the signal generator 13 of the first embodiment, a modulator for modulating a high-frequency carrier is required for outputting the generated signal L1 and for outputting W1. In the signal generation unit 53 of the present embodiment, the modulation is necessary only to generate the generation signal L1 to be supplied to the wireless transmission unit 11, and the modulation is necessary to generate the generation signal B1 to be supplied to the wired transmission unit 12. No need to do. This is because the generated signal B1 is a low frequency signal.

Further, the generated signal B1 is not a signal generated by performing a special conversion process or the like, but a modulation process when generating the generated signal W1 of the first embodiment is omitted, and is generated only by an encoding process. Since this signal is generated, it is not necessary to provide a special circuit for generating the signal.

Therefore, the signal generation unit 53 is provided, for example, in FIG.
May be provided with an internal configuration as shown in FIG.

In FIG. 5, a generated signal (low-frequency signal) B1 output from encoding section 53B is taken out from connection point P and supplied to wired transmission section 52 (see FIG. 1), and modulation section 53A. Is also supplied. The modulator 53A modulates the generated signal (coded signal) B1 by a predetermined modulation method to generate a generated signal (high-frequency signal) L1. Then, the generated signal (modulated signal) L1 is supplied to the wireless transmission unit 11.

The wire signal WS2 transmitted from the wire transmission section 52 to the twisted pair cable 71 as the wire transmission path WW1 based on the received generated signal B1 is also a low-frequency signal.

A low-frequency signal usually has a frequency of 30 kHz.
z or less, so the wired signal WS of this embodiment
The frequency 2 is much lower than the frequency of the radio signals LS1 and LS2 (for example, the aforementioned 315 MHz) in the present embodiment.

Further, in the first embodiment, it is necessary to selectively enable the wireless transmission unit 11 and the wired transmission unit 12 by using the mode signals MD1 and MD2. Its need is low.

[0132] It is composed of a radio signal LS1 and a wired signal WS2.
Are significantly different from each other, and there is almost no possibility that they interact with each other. Strictly speaking, the radio signal LS1, which is a high frequency, may have some influence on the transmission of the wired signal WS2, but the wired signal WS2, which is a low frequency signal, cannot affect the transmission of the radio signal LS1. .

Therefore, if necessary, the radio transmitting unit 11
It is also possible to adopt a configuration in which only the wireless transmission mode is enabled in the wireless communication mode and disabled in the wired communication mode, and the wired transmission unit 52 is always enabled.

In this case, since the mode signal MD2 becomes unnecessary, the scale of the mode switching section 15 can be reduced.

On the other hand, the remote control receiver 60 of the present embodiment
However, as shown in FIG. 3, the overall configuration is the same as that of the remote control receiver 20 of the first embodiment.

However, in the remote control receiver 60 of the present embodiment, the wired signal WS2 received by the wired receiving unit 62 is also a low-frequency signal, and the generated signal B2 to be transmitted is also a low-frequency signal. This is a circuit corresponding to the frequency signal.

More specifically, if a low-pass filter that cuts a high-frequency signal is mounted on the wired receiving section 62, for example, an interfering radio wave having the same frequency as the radio signal LS2 can be removed. Of course, the low-pass filter also cuts external high-frequency noise having a frequency different from that of the radio signal LS2.

However, if a low-pass filter is provided, there is a possibility that the waveform of the wired signal WS2 itself becomes large and the waveform distortion is increased depending on the filter characteristics. (If the waveform distortion is too large, a transmission error may occur. Therefore, if it is desired to obtain a nearly square pulse waveform as the generated signal B1, it may be necessary to set a high cutoff frequency to a higher value.

In the present embodiment, the remote control transmitter 50
Is not modulated by the signal generation unit 53 of
The reception processing unit 63 does not need to perform demodulation corresponding to the modulation.

In the remote control receiver 60, similarly to the remote control transmitter 50, the mode signal MD4 can be omitted, and the mode switching section 25 can be reduced in scale.

(B-2) Effects of the Second Embodiment As described above, according to the present embodiment, the same effects as those of the first embodiment can be obtained.

In addition, in the present embodiment, the signal generator (5
3), reception processing unit (62), mode switching unit (15, 2)
The configuration such as 5) can be simplified compared to the first embodiment, and the scale can be reduced.

The twisted pair cable (and the paired cable) used in the present embodiment is more excellent in workability than the coaxial cable used in the first embodiment, and is usually lower in price. In terms of price, it can be said that the mixing system of the present embodiment is superior to the mixing system of the first embodiment.

(C) Other Embodiments The first embodiment uses a high-frequency signal as the wired signal WS1, and the second embodiment uses the wired signal WS2.
However, according to the present invention, a function capable of coping with both the wired signal WS1 and the wired signal WS2 is installed in the remote control transmitter and the remote control receiver in advance. Alternatively, the configuration may be such that either one can be selected and used.

The remote control transmitter and the remote control receiver according to the first and second embodiments may be provided with an ID registration function for registering the above-mentioned ID and an ID collation function for collating the registered ID. Good. The ID registration function is provided by the processor 1
4 or the signal generation unit (13 or the like), and the ID collation function can be mounted on the processor 24 or the reception processing unit (23 or the like).

In the first and second embodiments, the radio signal is a radio wave of about 300 MHz or 400 MHz, but the scope of the present invention is not limited to this. Higher or lower frequency radio waves may be used, or infrared rays or the like may be used.

In the case of infrared rays, however, unlike radio waves, they do not diffract greatly or penetrate buildings, so that even in the wireless communication mode, the influence of interference hardly occurs in practical use. It is not considered possible. Therefore, it is considered that the factors for switching between the wireless communication mode and the wired communication mode are different from those described above. In the case of infrared radiation, there are no regulations such as the above-mentioned radio regulations. Therefore, the intensity of infrared radiation from the remote control transmitter is mainly determined by the pursuit of ease of use of the remote control transmitter and power consumption. This is considered to be a matter of balance with the pursuit of economic efficiency through reduction.

In the first and second embodiments, the present invention is applied to a garage shutter. However, the present invention can be applied to a shutter other than a garage shutter.

Furthermore, the present invention can be applied not only to shutters, but also to a mixture system of other opening / closing devices such as doors, windows, overhead doors, roll screens (for example, light shielding curtains), blinds, and awning devices. It is.

In the above description, the direction of information flow is basically one-way from the remote control transmitter to the remote control receiver. However, the scope of the present invention is limited to such one-way communication. It is not something to be done.

That is, the remote control transmitter is replaced with an operation transmitter / receiver which is a remote control transmitter / receiver instead of a transmission-only communication device, and the remote control transmitter / receiver is not a reception-only communication device but a remote controlled transmitter / receiver. It may be replaced with an operated transceiver which is a device so that full-duplex communication or half-duplex communication can be performed as necessary.

At this time, the signal included in the radio signal from the operation transceiver to the operated transceiver may be an operation state instruction signal for instructing the shutter operation or the like.
Conversely, the signal included in the radio signal from the operated transceiver to the operated transceiver may be an operation status report signal for reporting the current state of the shutter operation.

The operating state report signal indicates that the shutter operating state at that time is, for example, “fully open state”, “fully closed state”, “partially open state (partly opened and stopped). , "During opening operation", "during closing operation", "abnormality occurrence", and the like.

In this case, by receiving the operation state report signal, the user of the operation transceiver can recognize that the shutter operation state is, for example, the “fully open state”.

It is also possible to replace the operated transceiver with a portable receiver and replace the operated transceiver with a fixed transmitter. In this case, the information flows in a single direction from the fixed transmitter to the portable receiver. A system configuration in which only such one-way communication is always performed may be used, or a system configuration in which such one-way communication can be performed only when necessary according to mode switching.

That is, in the operation transceiver and the operated transceiver, only when necessary according to the mode switching,
Such one-way communication may be performed.

In the above description, the case where the communication device on the opening / closing body side is a remote operated device and the communication device on the non-opening / closing body side is a remote operation device has been described. However, the present invention is limited to this case. Not applicable.

It is also conceivable that the non-opening / closing body side communication device is a reception-only device that performs only reception.

This reception-only device is intended for, for example, maintenance and the like. The operation management information (opening / closing position of the opening / closing body, number of times of opening / closing, opening / closing failure information, And the like, and may display the reception result.

As for the transmission timing at which the opening / closing body side communication device transmits this operation management information, for example, the day of the week or the time is fixed in advance, or an arbitrary timing when a transmission instruction is given by wire. , Or the transmission timing.

Furthermore, the specific content of the operation management information transmitted at the transmission timing may be fixedly determined in advance, or only the specified content may be transmitted. .

[0162]

As described above, according to the present invention, a communication system for a switching device, a non-switching device-side communication device and a switching device-side communication device which are easy to use and have high reliability can be manufactured at a relatively low price. It can be provided by a small configuration.
