[0002]

2. Description of the Related Art The prior art of an electric winder system constituted by connecting a plurality of electric winders will be described with reference to FIGS. 7 and 9. FIG.

[0003] In a conventional communication mode, as shown in FIG. 7, one of a plurality of electric winding devices is set as a master unit 41,
The rest were set as slaves 42, 43, 44, 45. An operation switch 40 for operating the electric winding device is connected to the master unit 41.

[0006] First, an operation switch 40 is operated to transmit an operation command signal of the opening / closing member to the master unit 41. Base unit 4
1 receives the operation command signal from the operation switch, drives the opening / closing member, and transfers the operation command signal to the slave unit 42 so as to perform the same operation as the master unit 41. The slave unit 42 drives the opening / closing member based on the operation command signal,
The operation command signal is transferred to the adjacent slave unit 43. In this way, the operation command signal is transferred from the child device 43 to the child devices 44 and 45.

[0005] The electric winder system as described above uses a microcomputer to make connections as shown in FIG. FIG. 8 shows a modeled input / output terminal of the electric winding device shown in FIG. The electric winding devices 41 to 45 have input terminals 41a, 42a, 43, respectively.
a, 44a (not shown) and 45a (not shown);
It has one output terminal 41b, 42b, 43b, 44b (not shown), and 45b (not shown). The master unit 41 receives an operation command signal from the operation switch 40 from the input terminal 41a, drives the opening / closing member,
From the output terminal 41b to the input terminal 42a of the adjacent slave unit 42
To transfer the operation command signal. The slave unit 42 drives the opening / closing member based on the operation command signal, and transfers the operation command signal from the output terminal 42b to the input terminal 43a of the adjacent slave unit 43. Similarly, the operation command signal is sequentially transferred from the slave unit 43 to the slave units 44 and 45 in the same manner.

The circuit configuration of the electric winding device connected as described above will be described with reference to FIG. FIG. 9 (a)
FIG. 3 is a diagram showing a circuit configuration of a master unit 41. The master unit 41,
The motor unit 51 includes a motor (not shown) for driving the opening / closing member, an encoder (not shown) for detecting a rotational position of the motor, and a control device 52 for controlling the motor unit 51. An operation switch 59 and an adjacent slave unit 42 are connected to the control device 52.

The control device 52 includes a power supply circuit 53, a voltage detection circuit 54 for performing processing such as storing the position of the open / close member when the circuit voltage from the power supply circuit 53 decreases, and an encoder installed in the motor unit 51.

And the adjacent slave unit 42 is connected to the output terminal 58b.
Is connected to

FIG. 9B shows a slave unit 42 (slave units 43, 44,
FIG. 45 is a diagram showing a circuit configuration of 45). Since the motor unit and the control device are the same as the circuit configuration of the master unit 41 described above,
The description is omitted by attaching the same reference numerals. The difference from the master unit 41 is a circuit connected to the communication circuit 58 in the slave unit 42. The master terminal 41 is connected to the input terminal 58a of the communication circuit 58, and is adjacent to the output terminal 58b. The slave unit 43 is connected.

With the electric take-up device system configured as described above, two operation modes are set, one for operating only the parent machine and the other for operating the entire electric take-up system including the parent machine. , So that it is possible to perform a certain amount of individual operations.

However, in the electric take-up device system in which a plurality of electric take-up devices are connected as described above, data signals can be transmitted only when the operation switch is connected to the sub-unit. It is limited to sending to the side.

There is also a technique in which a reception terminal is provided in the operation switch and a signal from the output terminal 45b of the slave unit 45 in FIG. 7 is transmitted to the reception terminal, thereby forming the entire system into a loop shape. With such a configuration, the installation location of the operation switch cannot be set arbitrarily.

FIG. 10 shows an electric winder system in which the location of the operation switch can be set arbitrarily by eliminating the distinction between the master unit and the slave unit. This is the electric winding device 6
1, 62, 63 and 64 eliminate the distinction between the master unit and the slave unit, and each of the electric winding devices 61, 62, 63 and 64 has an output terminal 61a, 62a, 63a and 64a and an input terminal 61.

As shown in the figure, the output terminals 64b and the input terminals 61a of the electric winding devices 61 and 64 at both ends are connected to form a loop. Here, the operation switch 60 is connected to an operation switch connection terminal 61c of the electric winding device 61.

Assuming that the electric winding device 61 to which the operation switch 60 is connected is a master unit, the master unit 61
The operation command signals from 0 are sequentially transmitted to the adjacent electric winding devices 6.
2, 63, 64. And the electric winding device 6
4 returns the transmitted operation command signal to the master unit 61. Master device 61 transmits the transferred operation command signal to electric winding device 6.
4, the same operation command signal is not transferred any more.

As described above, all the electric winding devices 61, 6
The operation switch connection terminals 61c, 62c, 63c, 64c are formed as the third terminals on 2, 63, 64, and the electric winding device system is connected in a loop, so that the connection position of the operation switch 60 is arbitrary. Can be determined.

[0015]

Conventionally, when controlling an electric winding device system in which a plurality of electric winding devices are connected, a slave unit is connected to an electric winding device which is a master unit to which an operation switch is connected. It is only necessary to be able to transmit a data signal to the electric take-up device, and since the number of data signals to be transmitted was small in the past, there was no need to specify a destination when transmitting a data signal. However, the electric take-up device system having the above-described configuration can sufficiently cope with the problem.

However, in recent years, when the number of connected electric winding devices and the demand for high-precision control have been increased, various problems and problems have occurred when an electric winding device system is constructed with a conventional configuration. A point arises.

As one of them, in recent years, a case has arisen in which the transmission direction is not one-way but requires a reply. For example, there is a case where a question is issued on the operation switch side, and the electric winding device returns a data signal as an answer to the operation switch in response to the question. However, in the electric take-up device system configured as described above, the transmission direction of the data signal can be performed only in one direction, and the installation position of the master unit to which the operation switch can be connected is limited. Was gone. Furthermore, regarding the installation of the operation switches, for example, even when it is desired to provide operation switches at both ends of the electric take-up device system, such a configuration cannot be employed, and a configuration in which only one operation switch can be provided. In this case, it takes a long time before the data signal is transmitted to the electric winding device installed at the position farthest from the operation switch.

Further, as the number of connected electric winding devices increases, the time required for a data signal to be transmitted to the electric winding device farthest from the operation switch becomes longer and longer. There is an increasing demand for an electric take-up device system in which a plurality of operation switches can be installed. However, in the case of the above-described conventional configuration, transmission is one-way, so that one electric take-up device system is used. Had only one operating switch.

Further, as the number of electric winding devices increases, the number of data signals to be transmitted also increases. Conventionally, when a data signal is transmitted in an electric winder system, one transmitted data signal occupies all data lines. However, among the large number of data signals, only a small number of data signals are required for all electric winding devices, and most of the data signals are required only between the operation switch and the electric winding device to which the operation switch is connected. is there. In such a situation, for an electric take-up device, an unnecessary data signal occupies the data line, and it becomes impossible to immediately receive or transmit a necessary data signal. I was That is, the transmission efficiency of the data signal is significantly reduced.

In a case where the electric winding device is provided with an operation switch connection terminal and the electric winding device system is connected in a loop as described later in the prior art, the installation position of the operation switch is set arbitrarily. However, since the data signals are transferred in a loop, if a plurality of operation switches are installed, the possibility of collision of the plurality of data signals in the loop increases, and accurate transmission of the data signals can be achieved. No, leading to a decrease in the reliability of the electric winder system.

In the electric take-up device system, in addition to the above-mentioned problems and inconveniences, when constructed as a system, there is a demand for grasping the status of the opening / closing member and abnormal information. Such information could not be transferred to the operation switch (control command unit). [Configuration of the Invention]

1 to 4 show an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a circuit configuration diagram of the electric winding device of the present embodiment. In FIG. 1, reference numeral 1 denotes a motor unit including a motor (not shown) for vertically driving an opening / closing member (not shown) and an encoder (not shown) for detecting a rotational position of the motor. Reference numeral 2 in the figure denotes a control device for controlling the rotation of the motor of the motor unit 1.
The control device 2 includes a power supply circuit 3, a voltage detection circuit 4, an encoder processing circuit 5, a motor drive circuit 6, a microcomputer 7, and a communication circuit 8. And
The motor unit 1 and the control device 2 constitute one electric winding device.

The communication circuit 8 of the control device 2 includes a reception recognition circuit (not shown) for transmitting an operation command signal for raising and lowering the opening / closing member and recognizing reception of a data signal.
A communication observation circuit (not shown) for observing whether communication of data signals is performed between the control device 2 and the electric winding device or between other electric winding devices; an operation switch 9, a control unit 10 and 11 is tangent <br/> connection for other electric winding device disposed adjacent to the both sides in the present embodiment.

The power supply circuit 3 is a circuit for supplying a current to the circuit of the electric winding device, the power supply detection circuit 4, the power supply circuit 3
This is a circuit that performs processing such as storing the position of the opening / closing member when the circuit voltage from is lowered. The microcomputer 7, when supplied with current from the power supply circuit 3, Mo
Command to the motor unit 1 via the motor drive circuit
Send That is, the microcomputer 7 is a motor
Function as the heart of the control unit for
You. The motor unit 1 receives the rotation driving command, drives the motor to rotate, and transmits the rotation state of the motor as a pulse signal through the encoder. The pulse signal from the encoder is transmitted to the encoder processing circuit 5, and the encoder processing circuit 5 transmits to the microcomputer 7 a data signal relating to the rotation state for performing the rotation control processing of the motor based on the pulse signal. The microcomputer 7 receives the data signal relating to this rotation state, transmits a rotation control signal for controlling the rotation of the motor to the motor driving circuit 6, the motor driving circuit 6, the times <br/> rotation control The rotation of the motor constituting the motor unit 1 is actually controlled based on the signal.

The microcomputer 7 is connected to a communication circuit 8 for performing communication between the electric winding device and the operation switch and between the electric winding devices. Data signals from the control devices 10 and 11 of the other electric winding devices are transmitted to the microcomputer 7 and also to the operation switch 9 as reception recognition signals. The operation command signal from the operation switch 9 is also transmitted to the microcomputer 7.
Sent to Output from microcomputer 7
The data signal is also transmitted to the operation switch 9. The data signal transmitted to the other control devices 10 and 11 is transmitted to the other control devices 10 and 11 and also transmitted to the operation switch 9 as a reception recognition signal.

As described above, in this embodiment, the communication system between the electric take-up device and the communication system between the operation switch and the electric take-up device are not shared. Hereinafter, the operation and operation of the present embodiment will be described.

For example, a case where transmission from the operation switch 9 to the motor unit 1 is required will be described. First, an operation for winding up and closing the opening / closing member is performed by the operation switch 9 and an operation command for winding up the opening / closing member is issued. Assume that a signal is emitted. This operation command signal is transmitted to the microcomputer 7 via the communication circuit 8. The microcomputer 7 determines whether the transmitted operation command signal is a signal to be transferred to the motor unit 1 or a signal to be transferred to another control device 10 or 11. In this case, the operation command signal is transferred only to the motor unit 1 and is an operation command signal for driving the motor to wind up the opening / closing member. Therefore, the operation command signal is transferred only to the motor unit 1 via the motor drive circuit 6.

If the operation command signal is a data signal to be transmitted to the other control devices 10 and 11, the microcomputer 7 transfers the operation command signal to the motor unit 1 and transmits the operation command signal via the communication circuit 8. Control devices 10 and 11
Transfer the data signal to the At this time, the operation command signal passing through the communication circuit 8 is divided into two in the communication circuit 8, one of which is an operation command signal to be transferred to the other control devices 10 and 11, and the other to the operation switch 9. And an operation command signal to be transmitted.

The reason why the operation command signal is transferred to the operation switch 9 is to transmit the operation command signal to the reception recognition circuit provided in the operation switch 9. This reception recognition circuit will be described. For example, as shown in FIG. 2 described later, the operation switches 21 and 22 and the electric winding devices 23, 24,
It is assumed that when the switches 25 and 26 are connected, the operation switches 21 and 22 transmit data signals such as an operation command signal almost simultaneously. In this case, the electric winding device 23 that has received the operation command signal from the operation switch 21 and the operation switch 2
The electric winding device 25 that has received the operation command signal from the
At the same time, the received operation command signal is transmitted to another electric winding device (for example, the electric winding device 23). Then, in the electric winding device 24, the operation command signals transmitted from both sides cause a collision. In such a case, both operation command signals interfere with each other, and the electric winding device 24 cannot accurately receive either operation command signal, and cannot control the electric winding device system.

In order to prevent such a situation from occurring ,
In this embodiment, a reception recognition circuit is provided. This reception recognition
The circuit includes a reception recognizing unit that recognizes that any data signal is being received, and a transmission holding unit that temporarily suspends transmission of the data signal that was being transmitted or the data signal that was about to be transmitted. ing. Therefore, since transmission is not performed during reception of the data signal, collision of the data signal can be prevented. Then, the microcomputer 7 controls the motor driving circuit.
When the reception of the data signal transmitted to the road 7 is no longer recognized, the transmission of the data signal which has been put on hold is started.

Since all of the data signal transmitted to the control device 2 and the data signal transmitted from the microcomputer 7 are transferred to the reception recognition circuit,
Data signal collision can be prevented as much as possible. FIG.
Has four electric winding devices configured as described above,
FIG. 2 is a diagram illustrating a system configured by connecting two operation switches.

First, the case where the operation switch 21 is operated will be described. For example, by operating the operation switch 21,
Suppose that the electric winding devices 24 and 26 are to be operated. Therefore, the electric winding devices 24 and 2 are operated by the operation switch 21.
An operation for operating the opening / closing member 6 is performed, and an operation command signal for operating the opening / closing member is transmitted. The operation command signal is first transmitted to a microcomputer (not shown) of the electric winding device 23, and the microcomputer determines that the transmitted operation command signal is a data signal for the electric winding devices 24 and 26. Then, the operation command signal is transferred to the electric winding device 24. Next, the microcomputer (not shown) of the electric winding device 24 transmits the
Judgment that the operation command signal is
The opening / closing member is operated by driving the motor based on the above.
The operation command signal is transmitted to the microphone of the electric winding device 24.
The electric winding device 25 and the electric
It is also transferred to the winding device 26. And the electric winding device 2
In 6, the motor is driven based on the transmitted operation command signal to operate the opening / closing member.

Next, it is assumed that the user operates the operation switch 22 to operate the opening and closing members of the electric winding devices 24 and 26. In this case, the operation switch 22 performs an operation for operating the opening / closing members of the electric winding devices 24 and 26, and transmits an operation command signal for the operation. The operation command signal is transmitted to a microcomputer (not shown) of the electric winding device 25, and the transmitted operation command signal is transmitted to the electric winding devices 24 and 26 by the microcomputer.
Is transmitted to each of the electric winding devices 24 and 26. The microcomputer of the electric winding device 24 determines that the transmitted operation command signal is a data signal transmitted to itself, and drives the motor based on the operation command signal to open and close the opening / closing member. Make it work. Similarly, in the electric winding device 26 as well, the motor is driven based on the transmitted operation command signal to operate the opening / closing member.

Further, by operating the operation switch 21, the opening and closing member of the electric winding device 23 is operated, and the operation switch 22 is operated.
To operate the opening / closing member of the electric winding device 25. In this case, it is assumed that two operations are performed simultaneously. First, an operation command signal is transmitted from the operation switch 21, and at the same time, an operation command signal is transmitted from the operation switch 22. Then, the operation command signal from the operation switch 21 is transmitted to the electric winding device 23, and at the same time, the operation command signal from the operation switch 22 is transmitted to the electric winding device 25. However, each electric winding device 2
Since 3 and 25 determine that the transmitted operation command signal is a data signal addressed only to themselves, they are not transferred to another electric winding device (for example, 24). Therefore, even if the operation switches are simultaneously operated, no data signal collision occurs.

As described above, the communication system between the operation switch and the electric take-up device is different from the communication system between the electric take-up device, so that collision of data signals can be prevented as much as possible.
It is possible to improve the reliability of the system and further reduce the processing time of the data signal.

Here, an operation for operating the opening / closing member by driving the motor of the electric take-up device 23 from the operation switch 22 is performed, and the motor of the electric take-up device 25 is driven by the operation switch 21 to open / close the operation switch 21 with a slight delay. It is assumed that an operation for operating a member is performed. In this case, there is a possibility that the electric take-up device 23 may receive two data signals simultaneously. This case will be described with reference to the timing chart of FIG.

First, the operation switch 22 transmits the operation command signal B to the electric winding device 25 to which the operation switch 22 is connected, from t0 'to t1'. On the other hand, the operation switch 21 starts transmission from the operation switch 22 (t0).
′), The operation command signal A is transmitted from the electric winding device 2 to which the operation switch 21 is connected, from t0 to t1 slightly later than
Send to 3.

Since the electric take-up device 25 has received all the information of the operation command signal B, it recognizes that the operation command signal B is a data signal requiring transfer, and Is transmitted from t1 '. This operation command signal B is a signal for transmitting all information by being transmitted until t2 '. And this operation command signal B is
The operation switch 21, the electric winding device 23, and the operation switch 22 receive the information from t1 '.

When a data signal is transmitted during transmission, the operation switch and the electric take-up device temporarily stop the transmission and put it on hold, and give priority to receiving the transmitted data signal. When the operation switch 21 recognizes that the operation command signal B has been transmitted during the transmission of the operation command signal A, the operation switch 21 stops the transmission of the operation command signal A and puts the operation command signal A into a hold state. B
Is given priority.

Accordingly, in the electric winding device 23, the reception of the operation command signal A inevitably stops, and the reception of the operation command signal B starts at t1 '. It is determined that all the information has not been received due to the disconnection, and the retransmission request signal C, which has priority over reception and transmission of the operation command signal, is changed from t1 to t2.
To send. When the retransmission request signal C is transmitted, the electric winding device 25 stops the transmission of the operation command signal B, puts it on hold, and gives priority to the reception of the retransmission request signal C. Accordingly, the operation switch 21 and the operation switch 22 stop receiving the operation command signal B, and receive the transmitted retransmission request signal C instead.

The operation switch 21 and the electric winding device 25 which have received the retransmission request signal C try to start transmitting the operation command signal A and the operation command signal B, respectively. But,
The electric winding device 25 starts transmitting the operation command signal B at t2, but the operation switch 21 immediately switches the operation command signal A
Transmission is not started, reception confirmation is performed at regular intervals, and transmission is started after confirming that reception has not been performed. That is, when the retransmission request signal C is received
The electric take-up device transmits an operation command signal, but the operation switch
Switch does not immediately start transmitting the operation command signal,
After confirming that the operation command signal has not been
It is configured to start.

Accordingly, the transmission of all the information of the operation command signal B transmitted by the electric winding device 25 ends at time t3, and the operation switch 21 also finishes receiving all the information at time t3. I do. Therefore, the operation switch 21 confirms that the reception has been completed at time t3, and transmits an operation command signal A to the electric winding device 23 from t3 to t4, and the electric winding device 23 performs the operation command from t3 to t4. Signal A
Receive all information of The electric winding device 23 that has received the operation command signal A transmits the operation command signal A to the operation switch 21, the electric winding device 25, and the operation switch 22 from t4 to t5.

As described above, even if the operation switch 21 receives the retransmission request signal C, the transmission does not start immediately, the transmission of the operation command signal B from the electric winding device 25 ends, and the By confirming that there is no signal and then starting transmission of the operation command signal A which has been suspended, the operation command signal A and the operation command signal B can be reliably transmitted.

Here, a case where the system as shown in FIG. 2 is constructed with the electric winding device having no communication observation circuit as in the present embodiment will be described with reference to the timing chart of FIG.

First, the operation switch 22 is switched from t0 'to t1.
', And the electric winding device 25 receives the operation command signal B from t0' to t1 '. On the other hand, the operation switch 21 attempts to transmit the operation command signal A from t0 to t1. However, the electric winding device 25 that has finished receiving the operation command signal B determines that the transfer is necessary, and starts the electric winding device 23 from t1 ′.
The transmission of the operation command signal B is started. However, since this transmission causes the electric winding device 23 to receive both the operation command signal A and the operation command signal B during the period from t1 ′ to t1, both the operation command signals A and B are received. Interference occurs, and the operation command signal A cannot be accurately received.

Therefore, the electric take-up device 23 determines that the operation command signal A has not been correctly received, interrupts reception of the operation command signal B, and changes the retransmission request signal C from t1 to t.
2 to the operation switch 21 and the electric winding device 25. The operation switch 21 and the electric winding device 25 that have received the retransmission request signal C immediately start transmitting the operation command signal A and the operation command signal B from t2 to t3. A and B
Cause interference, and cannot correctly receive the respective operation command signals A and B. Therefore, t
The retransmission request signal C is transmitted to the operation switch 21 and the electric winding device 25 again from 3 to t4. Then, the operation switch 21 and the electric winding device 25 that have received the retransmission request signal C immediately resume transmission of the operation command signals A and B.

Thereafter, since the above-described simultaneous transmission is repeated, the operation command signals A and B cannot be accurately transmitted to the circuit to be transmitted (in this case, the electric winding device 23). Therefore, by using the electric take-up device having the configuration as in the present embodiment, the probability of occurrence of simultaneous transmission can be extremely reduced, and even if simultaneous transmission occurs, the operation command is promptly dealt with. It can be transmitted reliably. Next, a second embodiment of the electric take-up device system of the present invention will be described with reference to FIGS.

Conversely, with respect to the signals transmitted from the operation switch 80 and the control devices 81 and 82 of the electric winding device, a selection circuit 79 selects a circuit to be transmitted and transmission is performed only to a necessary circuit . Is configured.

As described above, in the present embodiment , transmission of a data signal from the operation switch to the electric winding device , transmission of a data signal from the electric winding device to the operation switch , and transmission of another data signal from the electric winding device to another electric winding device. transmission of the data signal to the winding device Nitsu
And select the destination in the selection circuit and select the required circuit .
It is configured to transmit data signals only for.
Hereinafter, the operation and operation of the present embodiment will be described.

First, in the case where the ratio between the transmitting side and the receiving side is 1: 1, the data signal is transmitted to the operation switch 80.
To the motor unit 71 only. The operation command signal transmitted from the operation switch 80 is first transmitted to the selection circuit 79. Selection circuit 79
In the above, the transmitted operation command signal is
1 or a data signal to be transmitted only to the control device 81 or 82 of the adjacent electric winding device, or a motor device 71 and a control device 81 of the adjacent electric winding device. , And 82 are transmitted. In this case, since the operation command signal is a data signal to be transmitted only to the motor unit 71, the selection circuit 79 is connected to the adjacent control devices 81 and 8
2. Refuse transmission and do not transmit. Then, as a data signal to be transmitted to the motor unit 71 side, the communication circuit 7
An operation command signal, which is a data signal, is transmitted to the microcomputer 77 through the microcomputer 9.
Transmits a data signal to the motor drive circuit 76 as a motor rotation control signal.

Next, a case where the transmission side and the reception side have a 1: 2 relationship will be described by taking as an example a case where transmission is performed from the operation switch 80 to both the motor unit 71 and the adjacent control devices 81 and 82. The operation command signal transmitted from the operation switch 80 is transmitted to the selection circuit 79, which determines a circuit to be transmitted. In this case, since the transmitting circuit is three electric winding devices including the adjacent electric winding devices 81 and 82, the selection circuit 79 transmits the operation command signal to the communication circuit 78 and the adjacent control device 81 , And 82 directly. The adjacent control circuits 81 and 82 control the rotational driving of the motor of the motor unit (not shown) based on the transmitted operation command signal.

Further, a case where the data signal needs to be returned will be described. As described above, the operation command signal is transmitted to the motor units 71. And the motor unit 71
A pulse signal of the rotational position from an encoder (not shown) installed in the encoder is transmitted to the encoder processing circuit 75. The encoder processing circuit 75 converts the pulse signal into a data signal for controlling the rotational position and transmits the data signal to the microcomputer 77. The microcomputer 77 converts the rotational position control data signal into a return data signal and transmits the return data signal to the communication circuit 78. For example, when the return signal is a data signal returned only to the operation switch 80, A command signal for transmitting only to the operation switch 80 is given to the selection circuit 79. The selection circuit 79 is configured to transmit a returned data signal to only the operation switch 80 based on a command signal from the microcomputer 77.

Similarly, when the reply destination is the operation switch 80 and the control devices 81 and 82 of the adjacent electric winding device, the microcomputer 77 operates the operation switch 8
0 and a command signal to be transmitted to the adjacent control devices 81 and 82 are given to the selection circuit 79, and the selection circuit 79 transmits a data signal to each of them based on the command signal.

With the electric winding device having the above-described configuration, in an electric winding device system in which a plurality of electric winding devices are connected as shown in FIG.
If each of a, 92a, 93a, 94a, 95a has a data signal to be transmitted only to the corresponding control device 91, 92, 93, 94, 95, the five operation switches 91a, 92a, 93a, 94a, It is possible to transmit data signals simultaneously from 95a. This is, for example, the operation switch 91a as in a conventional electric winding device.
Are transmitting data signals to the control device 91, the other operation switches 92a, 93a, 94a, and 95a cannot transmit data signals to be transmitted, and the control device 91
Even if the data signal is completely transmitted, only one data signal can be newly transmitted (for example, a data signal transmitted from the operation switch 92a to the control device 92). This is unnecessary and has a very excellent effect that all five data signals can be transmitted within one conventional transmission time.

In the second embodiment, the selection circuit is provided independently in the control device. However, the selection circuit is arranged in the microcomputer, and the data signal transmitted to the control device is It is possible to send all data to the microcomputer once, and to select the destination here.Also, it is possible to configure only a circuit that requires a data signal, such as forming a selection circuit in the communication circuit. Various modifications are naturally possible as long as they are transmitted and are not transmitted to circuits that do not need to transmit.

In the second embodiment, the description of the reception recognition circuit is omitted, but it is assumed that the reception recognition circuit is provided in the operation switch and the control circuit as in the first embodiment.

Further, between the operation switch and the electric winding device,
And a configuration in which a selection circuit for selecting a data signal to be transmitted is provided between the electric winding device and the electric winding device. It is possible to improve the reliability.

According to the electric take-up device system of the present invention, the communication system between the operation switch and the electric take-up device and the communication system between the electric take-up devices can be bidirectionally communicated. Communication observation means for observing
By providing reception recognition means for recognizing the reception of the data signal and transmission data holding means for temporarily holding the transmission of the data signal to be transmitted when the reception is recognized, the exchange of the data signal requiring a reply is facilitated. It is possible to prevent simultaneous transmission of data signals as much as possible, and even if simultaneous transmission occurs, it is possible to quickly cope with the situation and transmit the data signal without fail. It is possible to improve the reliability of the winding device system, and it is possible to make the system very functional.

Furthermore, since a selection circuit is provided for selecting and transmitting only a circuit that requires transmission of a data signal transmitted to the control device, transmission to an unnecessary circuit, that is, connection of an unnecessary circuit, is provided. Since the data line can be prevented from being occupied, even in a system in which a number of electric winding devices are connected, the data signal can be transmitted promptly and only to necessary circuits, so that the transmission efficiency of the data signal can be improved. Has an excellent effect that it is possible to significantly improve
