Abstract

PURPOSE:To obtain the system excellent in the function by forming a 2-way communication system between an operation switch and a motor-driven winder and a 2-way communication system between adjacent motor-driven winders differently from each other. CONSTITUTION:Suppose that an operation command signal for winding of a switch member is sent from an operation switch 9 to a motor section 1. The command signal is sent to a CPU 7 via a communication circuit 8. The CPU 7 applies discrimination processing to the sent command signal as to whether the signal is a signal to be transferred to the motor section 1 or a signal transferred to other controller 10 or 11. In this case, since the command signal is the command signal to be transferred to the motor section 1 only to wind up the switching member, the signal is transferred to the motor section 1 only via a motor drive circuit 6. When the command signal is a signal to be sent also to the controllers 10, 11, the CPU 7 transfers the data signal to the controllers 10, 11 via the circuit 8. In this case, the signal is divided into two in the circuit 8, the one signal is sent to the controllers 10, 11 and the other signal is fed to the switch 9 as an acknowledge signal.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric take-up device system in which a plurality of electric take-up devices used for awnings, blindfolds, etc., for winding and lowering an opening / closing member by a rotational driving force of a motor are connected. .

[0002]

2. Description of the Related Art A conventional technique of an electric winding device system configured by connecting a plurality of electric winding devices will be described with reference to FIGS. 7 and 9.

In the 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 parent device 41.

First, the operation switch 40 is operated to transmit an operation command signal for the opening / closing member to the parent device 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 child device 42 so as to perform the same operation as the parent device 41. The child device 42 drives the opening / closing member based on the operation command signal,
The operation command signal is transferred to the adjacent child device 43. In this way, the operation command signal is transferred from the handset 43 to the handset 44 and the handset 45.

The electric winding device system as described above uses a microcomputer to make connections as shown in FIG. FIG. 8 shows modeled input / output terminals 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), 45a (not shown),
Each of the output terminals 41b, 42b, 43b, 44b (not shown) and 45b (not shown) is provided. The parent device 41 receives an operation command signal from the operation switch 40 from the input terminal 41a, drives the opening / closing member, and
The input terminal 42a of the child device 42 adjacent to the output terminal 41b
The operation command signal is transferred to. The child device 42 drives the opening / closing member based on the operation instruction signal, and transfers the operation instruction signal from the output terminal 42b to the input terminal 43a of the adjacent child device 43. In the same manner, the operation command signal is sequentially transferred from the child device 43 to the child device 44 and the child device 45.

The circuit configuration of the electric winding device thus connected will be described with reference to FIG. FIG. 9 (a)
FIG. 3 is a diagram showing a circuit configuration of the master device 41. The base unit 41 is
The motor unit 51 includes a motor (not shown) that drives the opening / closing member, an encoder (not shown) that detects a rotational position of the motor, and a controller 52 that controls the motor unit 51. The operation switch 59 and the adjacent child device 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 opening / closing member when the circuit voltage from the power supply circuit 53 drops, and an encoder installed in the motor section 51. Encoder processing circuit 55 and encoder processing circuit 5 for processing the pulse signal from the
5, a motor drive circuit 5 for controlling the motor unit 51 based on the rotation control signal from the microcomputer 57.
6, a microcomputer 57, an operation switch 59, and a communication circuit 58 for communicating between the microcomputer 57 and the adjacent child device 42. Here, the operation switch 59 is the input terminal 58a of the communication circuit 58.
And the adjacent child device 42 is connected to the output terminal 58b.
Connected with.

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

By using the electric winding device system having the above-described configuration, two operation modes are set, one for operating only the parent device and one for operating the entire electric winding device system including the parent device. Therefore, it is possible to perform some individual operations.

However, in the electric winding device system in which a plurality of electric winding devices are connected as described above, the data signal can be transmitted only from the main unit side to which the operation switch is connected and the slave unit. It is limited to sending to the side.

There is also a technique in which the operation switch is provided with a receiving terminal and the signal from the output terminal 45b of the slave unit 45 in FIG. 7 is transmitted to this receiving terminal so that the entire system has a loop shape. With such a configuration, it is not possible to arbitrarily set the installation location of the operation switch.

Therefore, FIG. 10 shows an electric winding device system in which the installation position of the operation switch can be arbitrarily set without distinguishing between the parent device and the child device. This is an electric winding device 6
1, 62, 63, 64 eliminate the distinction between the master unit and the slave unit, and each electric winding device 61, 62, 63, 64 has an output terminal 61a, 62a, 63a, 64a and an input terminal 61.
b, 62b, 63b, 64b and operation switch connection terminals 61c, 62c, 63c, 64c are provided. Then, 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 each other so that they are connected in a loop. Here, the operation switch 60 is connected to the 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 the master unit, the master unit 61 has the operation switch 6
The operation command signals from 0 are sequentially applied 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 device 61. In the master device 61, the transferred operation command signal is transmitted by the electric winding device 6
4 is configured so that the same operation command signal will not be transferred anymore.

Thus, all the electric winding devices 61, 6
By forming operation switch connection terminals 61c, 62c, 63c, 64c as third terminals on the terminals 2, 63, 64 and connecting the electric winding device system in a loop shape, the operation switch 60 can be connected at any position. It becomes possible to decide.

[0015]

Conventionally, when controlling an electric winding device system in which a plurality of electric winding devices are connected, from the electric winding device, which is the parent device to which the operation switch is connected, to the slave device. It suffices to be able to send a data signal to the electric winding device that is, and in the past, since the number of data signals to be sent was small, it was not necessary to specify the destination when sending the data signal. The electric winding device system having the above-described configuration has been able to sufficiently deal with the problem.

However, in recent years, when the number of connected electric winding devices and the demand for high-accuracy control have increased, various problems and problems will occur when an electric winding device system is constructed with a conventional configuration. Dots come up.

As one of them, in recent years, there has been a case where the transmission direction is not one-way and a reply is required. For example, there is a case where the operation switch side issues a question, and the electric winding device side responds to this question with a data signal as an answer to the operation switch. However, in the electric winding device system configured as described above, the data signal can be transmitted only in one direction, and the installation position of the parent device to which the operation switch can be connected is limited. I was sick. Further, with regard to the installation of the operation switch, even when it is desired to provide the operation switch at both ends of the electric winding device system, such a configuration cannot be provided and only one operation switch can be provided. In that case, it takes a long time to transmit the data signal to the electric winding device installed at the position farthest from the operation switch.

Further, when the number of connected electric winding devices increases, the time until the data signal is transmitted to the electric winding device farthest from the operation switch becomes longer and longer, which is inevitable. Although there is an increasing demand for an electric winding device system capable of installing a plurality of operation switches, in the case of the conventional configuration as described above, since the transmission is one-way, one electric winding device system is provided. Only one operating switch could be installed in.

Furthermore, 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 winding device system, one transmitted data signal occupies all the data lines. However, of the many data signals, only a few data signals are required for all electric winding devices, and most 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 winding device, an unnecessary data signal occupies the data line, and it becomes impossible to immediately receive or transmit the necessary data signal. Was there. That is, the transmission efficiency of the data signal is significantly reduced.

In the case where the electric winding device is provided with an operation switch connecting terminal and the electric winding device system is connected in a loop shape as described in the latter part of the above-mentioned prior art, the installation position of the operation switch is arbitrarily set. However, since data signals are transferred in a loop, installing multiple operation switches increases the possibility that multiple data signals will collide in the loop, and accurate data signal transmission will be possible. This is not possible, leading to a decrease in the reliability of the electric winding device system.

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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to. FIG. 1 is a circuit configuration diagram of the electric winding device of the present embodiment. In the figure, reference numeral 1 is a motor unit including a motor (not shown) for vertically moving 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.

A reception recognizing circuit (not shown) is provided to the communication circuit 8 of the control device 2 for transmitting an operation command signal for winding and lowering the opening / closing member and recognizing the reception of the data signal.
And an operation switch 9 provided with a communication observation circuit (not shown) for observing whether data signal communication is performed between other electric winding devices, and another electric winding device adjacent to both sides. The control devices 10 and 11 are connected.

The power supply circuit 3 is a circuit that supplies a current to the circuit of the electric winding device, and the voltage detection circuit 4 stores the position of the opening / closing member when the circuit voltage from the power supply circuit 3 decreases. It is a circuit that performs processing. When the microcomputer 7 is supplied with current from the power supply circuit 3, the microcomputer 7 transmits a rotation drive command for the motor to the motor unit 1 via the motor drive circuit 6. The motor unit 1 receives the rotation drive command to rotate the motor, and the encoder outputs the rotation state as a pulse signal. The pulse signal from this encoder is transmitted to the encoder processing circuit 5, and the encoder processing circuit 5 transmits to the microcomputer 7 a data signal for performing rotation control processing of the motor based on this pulse signal. The microcomputer 7 receives the data signal for rotation control processing and transmits a rotation control signal for controlling the rotation of the motor to the motor drive circuit 6. The motor drive circuit 6 controls the rotation of the motor of the motor unit 1 based on the rotation control signal.

The microcomputer 7 is connected to a communication circuit 8 for communication between the electric winding device and the operation switch and between the electric winding device. Data signals from the control devices 10 and 11 of the other electric winding device are transmitted to the microcomputer 7 and also to the operation switch 9 as a reception recognition signal. Further, the operation command signal from the operation switch 9 is also supplied to the microcomputer 7.
Sent to. The data signal output from the microcomputer 7 is transmitted only to the operation switch 9 when the data signal is transmitted to the operation switch 9. The data signal to be transmitted to the other control devices 10 and 11 is the other control device 1
The signal is transmitted to 0 and 11 and is also transmitted to the operation switch 9 as a reception recognition signal.

As described above, in this embodiment, the communication system between the electric winding device and the communication system between the operation switch and the electric winding device are configured not to be a common system. The operation and action of this embodiment will be described below.

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 driving the hoisting of the opening / closing member is performed by the operation switch 9, and an operation command for hoisting the opening / closing member is performed. Suppose a signal is emitted. This operation command signal is transmitted to the microcomputer 7 via the communication circuit 8. Then, in the microcomputer 7, it is determined 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 to drive the motor to wind up the opening / closing member, and thus the operation command signal is transferred only to the motor unit 1 via the motor drive circuit 6.

When 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 also transmits the other data via the communication circuit 8. Control devices 10 and 11
Transfer data signal to. 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 used as the operation command signal transferred to the other control devices 10 and 11 and the other to the operation switch 9. And the operation command signal to be transmitted.

The operation command signal is transferred to the operation switch 9 in order to transmit the operation command signal to the reception recognition circuit installed 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,
When 25 and 26 are connected, it is assumed that the operation switches 21 and 22 transmit data signals such as operation command signals almost at the same time. In this case, the electric take-up 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
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, the electric winding device 24 cannot accurately receive either operation command signal, and the electric winding device system cannot be controlled.

A reception recognition circuit is provided in order to prevent the occurrence of such a situation. When the reception recognition circuit recognizes that some data signal is received, it transmits the data signal being transmitted. Alternatively, the data signal to be transmitted is once placed in a hold state to stop the transmission. Therefore, since the data signal is not transmitted during reception, it is possible to prevent the data signal from colliding. Then, when the reception of the reception of the transmission of the data signal from the microcomputer 7 is no longer recognized, the transmission of the data signal in the hold state is started.

Since all the data signals transmitted to the control device 2 and the data signals transmitted from the microcomputer 7 are transferred to this reception recognition circuit,
The collision of data signals can be prevented as much as possible. Figure 2
Includes four electric winding devices configured as described above,
It is a figure which shows the system comprised 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 you want to operate the electric winding devices 24 and 26. Therefore, in the operation switch 21, the electric winding devices 24 and 2
The operation command signal for operating the opening / closing member 6 is transmitted. This 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 receives the operation command signal transmitted to itself and the electric winding device 26.
Is determined to be an operation command signal to be transmitted to the motor, the motor is driven based on the operation command signal to operate the opening / closing member, and the operation command signal is transferred to the electric winding device 25. The microcomputer (not shown) of the electric winding device 25 determines that the transmitted operation command signal is the signal transmitted to the electric winding device 26, and outputs the operation command signal to the electric winding device 26. Forward. Then, in the electric winding device 26, the motor is driven based on the transmitted operation command signal to operate the opening / closing member.

Next, it is assumed that the operation switch 22 is operated to operate the opening / closing members of the electric winding devices 24 and 26. In this case, the operation switch 22 is operated to operate the opening / closing members of the electric winding devices 24 and 26, and an operation command signal for operation is transmitted. The operation command signal is transmitted to a microcomputer (not shown) of the electric winding device 25, and the operation command signal transmitted by the microcomputer is used by the electric winding devices 24 and 26.
It is determined that the operation command signal is for the electric winding device 24 and is transferred 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 the data signal transmitted to itself, and drives the motor based on the operation command signal to open the opening / closing member. To operate. Similarly, also in the electric winding device 26, the motor is driven based on the transmitted operation command signal to operate the opening / closing member.

Further, the operating switch 21 is operated to operate the opening / closing member of the electric winding device 23, and the operating switch 22 is operated.
Want to operate the opening / closing member of the electric winding device 25 by operating. In this case, it is assumed that two operations are performed at the same time. First, the operation command signal is transmitted from the operation switch 21, and at the same time, the 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 itself, they are not transferred to another electric winding device (for example, 24). Therefore, even if the operation switches are operated at the same time, the collision of data signals does not occur.

As described above, by making the communication system between the operation switch and the electric winding device and the communication system between the electric winding devices different systems, collision of data signals can be prevented as much as possible.
The reliability of the system can be improved and the processing time of the data signal can be shortened.

Here, the operation switch 22 drives the motor of the electric winding device 23 to operate the opening / closing member, and after a slight delay, the operation switch 21 drives the motor of the electric winding device 25 to open / close. It is assumed that an operation for moving the member is performed. In this case, the electric winding 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 from t0 'to t1' to the electric winding device 25 connected to the operation switch 22. On the other hand, the operation switch 21 starts transmission from the operation switch 22 (t0
From t0 to t1 which is slightly later than ′), the electric winding device 2 in which the operation command signal A is connected to the operation switch 21.
Send to 3.

Since the electric winding device 25 has received all the information of the operation command signal B, it recognizes that this operation command signal B is a data signal that needs to be transferred, and the operation command signal B is recognized. Is transmitted from t1 ′. This operation command signal B is a signal that transmits 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 from t1 '.

When a data signal is transmitted during transmission, the operation switch and the electric winding device temporarily stop the transmission and put it in a hold state, and prioritize the reception of 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 it in the hold state, B
Is preferentially received.

Along with this, the electric winding device 23 inevitably stops receiving the operation command signal A, and the reception of the operation command signal B starts from t1 ', but the operation command signal A is in the middle. It is judged that all the information has not been received, and the retransmission request signal C, which has priority over reception and transmission of the operation command signal, is transmitted from t1 to t2.
To send. By the transmission of the retransmission request signal C, the electric winding device 25 stops transmission of the operation command signal B and puts it in the hold state, and gives priority to the reception of the retransmission request signal C. Along with this, the operation switches 21 and 22 stop receiving the operation command signal B, and instead, receive the transmitted retransmission request signal C.

Upon receiving the retransmission request signal C, the operation switch 21 and the electric winding device 25 try to start the transmission of 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 from t2, but the operation switch 21 immediately outputs the operation command signal A.
Is not started, the reception is confirmed at regular intervals, and the transmission is started after confirming that no reception has been made.

Therefore, all the information of the operation command signal B transmitted by the electric winding device 25 ends at the time t3, and the operation switch 21 also finishes receiving all the information at the time t3. To do. Therefore, the operation switch 21 confirms that the reception is completed at time t3, and transmits the operation command signal A to the electric winding device 23 from t3 to t4, and the electric winding device 23 outputs 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 when the operation switch 21 receives the retransmission request signal C, the transmission does not start immediately, and the transmission of the operation command signal B from the electric winding device 25 ends and the received data is received. The operation command signal A and the operation command signal B can be reliably transmitted by adopting a configuration in which the transmission of the operation command signal A, which has been held until then, is started after confirming that there is no signal.

Here, a case where the system as shown in FIG. 2 is constructed by the electric winding device which does not have the communication observation circuit as in this embodiment will be described with reference to the timing chart of FIG.

First, the operation switch 22 moves from t0 'to t1.
The operation command signal B is transmitted to the electric winding device 25, and the electric winding device 25 receives the operation command signal B from t0 'to t1'. On the other hand, the operation switch 21 tries to transmit the operation command signal A from t0 to t1. However, the electric winding device 25, which has received 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 to is started. However, due to this transmission, the electric winding device 23 receives the data signals of both the operation command signal A and the operation command signal B from t1 ′ to t1, so that both operation command signals A and B are received. This causes interference and makes it impossible to accurately receive the operation command signal A.

Therefore, the electric winding device 23 judges that the operation command signal A is not correctly received, interrupts the reception of the operation command signal B, and sends the retransmission request signal C from t1 to t.
It transmits to the operation switch 21 and the electric winding device 25 over 2. 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, but in the electric winding device 23, the operation command signal again. A and B
Interfere with each other and cannot accurately receive the respective operation command signals A and B. Therefore, t
From 3 to t4, the retransmission request signal C is transmitted again to the operation switch 21 and the electric winding device 25. Then, the operation switch 21 and the electric winding device 25 that have received the retransmission request signal C immediately restart the transmission of the operation command signals A and B.

Since the simultaneous transmission as described above is repeated thereafter, 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 winding device configured as in the present embodiment, the probability of simultaneous transmission can be significantly reduced, and even if simultaneous transmission occurs, it is possible to promptly deal with the operation command. It can be sent reliably. Next, a second embodiment of the electric winding device system of the present invention will be described with reference to FIGS.

The selection circuit 79 of the control device 72 is provided with an operation switch 80 provided with a reception recognition circuit (not shown) for transmitting operation command signals for winding and lowering the opening / closing member and recognizing reception of the data signal. , Control devices 81 and 82 of the other electric winding device adjacent to both sides are connected.

The power supply circuit 73 is a circuit for supplying a current to the circuit of the electric winding device, and the voltage detection circuit 74 stores the position of the opening / closing member when the circuit voltage from the power supply circuit 73 drops. It is a circuit that performs processing. When the current is supplied from the power supply circuit 73, the microcomputer 77 sends another rotation drive command to the motor unit 71 via the motor drive circuit 76. The motor unit 71 receives the rotational drive command and rotationally drives the motor, and the encoder outputs the rotational state as a pulse signal. The pulse signal from this encoder is transmitted to the encoder processing circuit 75,
The encoder processing circuit 75 transmits a data signal for performing rotation control processing of the motor to the microcomputer 77 based on this pulse signal. Microcomputer 77
Receives a data signal for rotation control processing and outputs a rotation control signal for controlling rotation of the motor to the motor drive circuit 76.
Send to. The motor drive circuit 76 controls the rotation of the motor of the motor unit 71 based on the rotation control signal.

A communication circuit 78 for communicating between the electric winding device and the operation switch and between the electric winding device is connected to the microcomputer 77. The communication circuit 78 is connected to the microcomputer. A selection circuit 79 for selecting a transmission destination of the data signal transmitted from 77 to the communication circuit 78 by a signal from the microcomputer 77 and transmitting it to only a circuit that needs transmission is connected.

Further, the selection circuit 79 is provided with an operation switch 80 provided with a reception recognition circuit (not shown) for transmitting operation command signals for winding and lowering the opening / closing member and recognizing reception of the data signal. Control devices 81 and 82 of another electric winding device adjacent to both sides of this electric winding device are connected. Then, the selection circuit 79 transmits the data signal transmitted from the communication circuit 78 to the operation switch 80 or the control device 81 or 82 of the adjacent electric switchgear according to a command from the microcomputer 77. On the contrary, the signals transmitted from the operation switch 80 and the control devices 81 and 82 of the adjacent electric winding device are the selection circuit 7.
In 9, the circuit to be transmitted is selected, and transmission is performed only to the necessary circuit.

As described above, in the present embodiment, the selection circuit transmits the data signal from the operation switch to the electric winding device, from the electric winding device to the operation switch, and from the electric winding device to another electric winding device. In (1), the transmission destination is selected and the data signal is transmitted only to necessary circuits. The operation and action of this embodiment will be described below.

First, in the case where the ratio between the transmitting side and the receiving side is 1: 1, the data signal is changed to the operation switch 80.
The description will be given by taking as an example the case where the data is transmitted from the vehicle 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
, The operation command signal transmitted is the motor unit 7
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 unit 71 and a control device 81 of the adjacent electric winding device. And 82, it is determined whether the data signal is a data signal to be 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 causes the adjacent control devices 81 and 8 to operate.
Do not send to 2 and refuse to send. Then, as a data signal to be transmitted to the motor section 71 side, the communication circuit 7
An operation command signal, which is a data signal, is transmitted to the microcomputer 77 via the microcomputer 77.
Sends 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 the case of transmitting from the operation switch 80 to both the motor section 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, and the circuit to be transmitted is determined here. In this case, since the circuits to be transmitted are the 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 to the operation command signal. Adjacent control circuits 81 and 82 control the rotation drive of the motor of the motor unit (not shown) based on the transmitted operation command signal.

Further, the case of a data signal that requires a reply will be described. The operation command signal is transmitted to the motor units 71 ... As described above. Then, the motor unit 71
The pulse signal of the rotational position from the encoder (not shown) installed in (1) is transmitted to the encoder processing circuit 75. The encoder processing circuit 75 converts this pulse signal into a data signal for controlling the rotational position and transmits it to the microcomputer 77. The microcomputer 77 converts the rotational position control data signal into a reply data signal and sends the reply data signal to the communication circuit 78. When the reply signal is a data signal to be returned only to the operation switch 80, for example, A command signal to the effect that only the operation switch 80 is transmitted is given to the selection circuit 79. The selection circuit 79 is configured to transmit the returned data signal only to the operation switch 80 based on the 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 causes the operation switch 8 to operate.
0 and a command signal to the effect that it is 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 based on the command signal.

When the electric winding device having the above-mentioned structure is used, in the electric winding device system in which a plurality of electric winding devices are connected as shown in FIG.
If each of the a, 92a, 93a, 94a, and 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, an operation switch 91a like a conventional electric winding device.
While transmitting a data signal to the control device 91, the other operation switches 92a, 93a, 94a, 95a cannot send the data signal to be transmitted, and the control device 91
Even if the data signal has been transmitted to the control unit, only one data signal can be newly transmitted (for example, the data signal transmitted from the operation switch 92a to the control device 92). It is unnecessary and has a very excellent effect that all five data signals can be transmitted within one transmission time in the related art.

In the second embodiment, the selection circuit is independently provided in the control device. However, by arranging the selection circuit in the microcomputer, the data signal transmitted to the control device is It is also possible to send all the data to the microcomputer and select the destination here, or configure only the circuit that requires the data signal, such as configuring the selection circuit in the communication circuit. Various modifications are naturally possible as long as the configuration is such that it is transmitted and not transmitted to a circuit that does not need to transmit.

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

Further, between the operation switch and the electric winding device,
By adopting a configuration in which bidirectional communication is possible between the electric winding device and a selection circuit for selecting a data signal to be transmitted, the electric winding device system of the above-described first and second embodiments is provided. It is possible to improve reliability.
