However, the controller 2 and the controller 1 and the central controller A of the remote monitoring and control system
The signal transmission is performed by time division multiplexing between and, and the opening / closing control of the shutter is performed by the controller 1 according to the operation of the operation device 2.

First, a remote monitoring control system incorporating the electric shutter system of the present invention will be described. As shown in FIG. 1, the remote monitoring control system includes a load Z such as a lighting fixture, a switch for inputting an operation input for controlling the operation of the load Z, and a monitoring terminal device C for monitoring the operation state of the switch. A plurality of control terminals B for controlling the operation of the load Z, and the control terminal B and the monitoring terminal C are connected to the control terminal B and the monitoring terminal C by a two-wire signal line L, and are time-shared between the control terminal B and the monitoring terminal C. It is composed of a central control unit A which performs signal transmission by multiplexing. In the case of FIG. 1, the switch is the monitoring terminal C.
It is provided integrally with. Further, generally, the central control unit A is housed together with a breaker BR in an electric installation board F such as a distribution board.

A unique address is set in each of the control terminal B and the monitoring terminal C, and the central control unit A specifies each address of the control terminal B or the monitoring terminal C in the transmission signal, so that each control is performed. The terminal device B or the monitoring terminal device C is individually accessed to perform signal transmission by time division multiplexing with the respective control terminal device B and the monitoring terminal device C. Transmission signal V _S, as shown in FIG. 4, a start pulse ST indicating the start of transmission, the mode data MD indicating the type of transmission signal V _S, the destination terminal device B of the transmission signal V _S, specifying the C Address data AD, control data CD indicating the content of the control command, transmission error detection data (for example, checksum data) C added to check a transmission error.
S, a response period WT provided for returning a signal from the terminals B and C to the central control unit A. This transmission signal V _S is transmitted as a bipolar (± 24 V) pulse width modulation signal.

Upon receiving an operation input from the monitoring terminal C, the central control unit A creates control data CD indicating the command contents of the operation control of the load Z based on the operation input and sends it to the control terminal B. To do. The control terminal B is the central control unit A.
When the address data AD of the transmission signal transmitted from the device coincides with its own address, the control data CD of the transmission signal V _S is fetched. Then, the monitoring data indicating the operating state of the load Z based on the control data CD is returned to the central controller A in synchronization with the reply period WT. During the reply period WT, the transmission signal V _S is kept at a positive potential (+24 V), and the control terminal device B sets the two-wire type signal lines L to a substantially short-circuited state to the central controller A in the current mode.

The operation of shifting from the standby state to the operation of transmitting signals with the terminals B and C described above will be described below. As a request for performing this signal transmission, an interrupt pulse V _i shown in FIG. 4B is transmitted from the terminals B and C to the central control unit A in synchronization with the start pulse ST of the dummy transmission signal. Since this type of interrupt request is mainly made from the monitoring terminal device C when the switch S is operated, the case where an interrupt request is made from the monitoring terminal device C will be described below.

In the central control unit A which has received the interrupt request, the mode data MD is set to the address specifying mode for specifying the monitoring terminal device C which has made the interrupt request, and the monitoring terminal device C which has made the interrupt request is set. Identify. In this case,
There is also a method of specifying the interrupt request terminal device C by performing polling for individually accessing each monitoring terminal device C. However, in this embodiment, in order to quickly specify the interrupt request terminal device C, the upper several bits of the address data are specified,
A group access is performed to collectively access a plurality of monitoring terminals C as a group, and the monitoring terminal C that has made an interrupt request sends back the remaining lower-order bits to the central control unit A during the reply period WT. The method of notifying the central control unit A that it has made an interrupt request is adopted.

When the monitoring terminal device C which has made the interrupt request is specified as described above, the central control unit A specifies the monitoring terminal device C which has made the interrupt request by the address data and operates the switch S. Send back monitoring data indicating the status. The central controller A that has received the monitoring data creates control data based on the monitoring data, and transmits the control data to the control terminal B to which the load Z corresponding to the monitoring data is connected.

By the way, although the operating device 2 has no function of displaying the opening / closing operation state of the shutter 3, it may be provided with an opening / closing operation display function. The appearance of the operating device 2 in that case is shown in FIG. That is, the light emitting diodes LED ₁ and LED ₂ are provided on the shoulders of the opening operation switch SW ₂₁ and the closing operation switch SW ₂₃ provided on the front surface of the cover 32. The light emission control of the light emitting diodes LED ₁ and LED ₂ is performed by the signal processing circuit 20 according to the control data given from the central control unit A according to the monitoring data from the controller 1.

Next, the controller 1 will be described.
As shown in FIG. 8, the controller 1 includes a signal transmission unit 12 that performs signal transmission with the central control device A via a signal line L, and signal processing that performs signal processing with the central control device A. And a section 10. Here, the signal transmission unit 12
It is composed of the diode bridge DB ₁ described in the operation device 2, the power supply circuit 22, the receiving circuit 23, and the reply circuit 24. The signal processing unit 10 includes a signal processing circuit 20, an oscillation circuit 25, a reset circuit 26, and an address setting unit. 21 and. The power supply for each of the units 10 and 12 can be obtained from a power supply circuit 13 described later.

In addition to the motor control circuit 11 that controls the operation of the motor M that drives the shutter 3 to open and close, and the signal transmission system, the controller 1 also includes a commercial power supply (AC1).
(00V), a power supply circuit 13 for generating a power supply for the shutter opening / closing control system, and a sensor control circuit 15 for supplying power to the sensor S for detecting an object only when necessary (when closing the shutter 3) to operate. . The signal processing unit 10 also has a central function of signal processing of the shutter opening / closing control system.

The controller 1 includes, as an accessory device, an encoder E for detecting the number of rotations of the motor M, and a sensor S for detecting an object to prevent an object or a person from being caught when the shutter 3 is closed. And a lower limit detection switch SW ₁ for detecting that the shutter 3 is completely closed, and performs shutter opening / closing control, which will be described in detail later, and signal transmission to the operating device 2 in accordance with the respective outputs.

The operation of the controller 1 will be described below with reference to FIG. In addition, the following description will be given with respect to the light emitting diodes LED ₁ and LED ₁ for displaying the opening or closing operation of the operating device 2.
Do this for cases that include ₂ . Now, assuming that control data (opening operation signal) for opening the shutter 3 is given via the central control unit A in response to the operation of the opening operation switch SW ₂₁ of the operating device 2, at this time, a signal is sent via the signal transmission unit 12. In response to the opening operation signal captured by the processing unit 10, FIG.
As shown in FIG. 3, the signal processing unit 10 gives a control signal for driving the motor M to open the shutter 3 to the motor control circuit 11. As a result, the shutter 3 is opened.

During the opening operation of the shutter 3, the signal processor 10 detects the rotation speed of the motor M from the output of the encoder E, and the shutter 3 is completely opened due to the decrease in the rotation speed of the motor M. Detect that It should be noted that until the number of rotations of the motor M drops below a certain level, monitoring data (a rising signal) indicating that the shutter 3 is opened is returned to the central controller A. In accordance with the monitoring data at this time, the central control unit A sends control data for lighting the light emitting diode LED ₁ for opening operation display to the operating device 2 and lights the light emitting diode LED ₁ .

When the shutter 3 is completely opened, that is, when the rotation speed of the motor M drops below a certain level, the signal processing section 10 controls the motor control circuit 11 to stop the rotation of the motor M. Give a signal. At this time,
The signal processing unit 10 sends monitoring data (upper limit signal) indicating that the motor M is stopped to the central control unit A.
Here, if the central control unit A polls each control terminal device B at the time of sending the dummy transmission signal to monitor the operating condition of the load Z, an ascending signal indicating that the shutter 3 is opened. Does not send a reply to the central control unit A and sends an upper limit signal indicating that the opening operation of the shutter is stopped when the controller 1 is accessed while the shutter 3 is completely opened. May be replied to. As another method, the controller 1 may be provided with a function of performing an interrupt process as in the monitoring terminal device C, and an upper limit signal may be returned by the interrupt process when the opening operation of the shutter is stopped.

In this way, when the upper limit signal indicating the stop of the opening operation of the shutter 3 is given to the central control unit A, the central control unit A displays the opening action for the operating device 2 according to the upper limit signal. Control data for turning off the light emitting diode LED ₁ is sent to turn off the light emitting diode LED ₁ . On the contrary, when the monitoring data (closing operation signal) indicating that the closing operation switch SW ₂₃ is operated is returned from the operation device 2 to the central control device A, the closing operation of the shutter 3 is performed. At this time as well, in the same manner as during the opening operation, signal transmission is performed via the central control unit A, and the monitoring data (descent signal) indicating that the shutter is closed is used to display the closing operation of the operating device 2. The light emitting diode LED ₂ is turned on.

When the shutter 3 is closed in this way, the sensor control circuit 15 supplies the power from the power supply circuit 13 to the sensor S, and the sensor S starts the object detection. The output indicating the object monitoring status of the sensor S is the signal processing unit 10.
Given to. Further, even during the closing operation of the shutter 3, the signal processing unit 10 detects the rotation speed of the motor M from the output of the encoder E. Further, the signal processing unit 10 monitors the on / off state of the lower limit detection switch SW ₁ .

Here, the detection of the object by the sensor S and the detection of the rotation speed of the motor M are for preventing a person or an object from being caught in the shutter 3 during the closing operation of the shutter 3.
The fact that the shutter 3 is completely closed is detected by the ON / OFF state of the lower limit detection switch SW ₁ . Now, for example, when an object is detected by the sensor S, or the number of rotations of the motor M drops below a predetermined value, or when both states occur simultaneously, the closing operation of the shutter 3 is forcibly stopped. This prevents people or objects from being caught in the shutter 3. The shutter 3
May be forcibly reversed from the closing operation to the opening operation.

When such an abnormality occurs, the signal processing unit 10 sends monitoring data (abnormality signal) indicating the occurrence of the abnormality to the central control unit A. At this time, the central control unit A controls the light emitting diodes LED ₁ and LED _{2 of the} operating device _2.
The abnormality is displayed by giving control data for alternately turning on. It should be noted that another indicator may be provided in the operation device 2 for displaying an abnormality.

When the lower limit detection switch SW ₁ detects that the shutter 3 is completely closed, the closing operation of the shutter 3 is stopped and the light emitting diode LED ₂ of the operating device ₂ is turned off. When the stop operation switch SW ₂₂ is operated (a stop operation signal is returned) during the opening / closing of the shutter 3, the controller 1 stops the opening / closing operation of the shutter 3, and the light emitting diode LED of the operation device 2 is stopped.
₁ or monitoring data (intermediate stop signal) for turning off the light emitting diode LED ₂ is returned. Here, when the odor stop operation switch SW ₂₂ is operated during opening and closing, a display indicating that the shutter 3 is stopped in the intermediate state may be displayed. For example, the stop operation performed during the opening operation is indicated by blinking of the light emitting diode LED ₁ , and the stop operation during the closing operation is performed by the light emitting diode LE.
It may be indicated by blinking D ₂ .

As described above, in this embodiment, the controller 1 and the operating device 2 for opening and closing the conventional shutter are provided with a function as a terminal device of the remote monitoring control system.
By incorporating it in the remote monitoring and control system, the wiring between the controller 1 and the operating device 2 can be a two-wire system.
