When the central controller A receives an operation input from the monitoring terminal C, the central controller 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.
Address data AD of the transmission signal V _S transmitted from a time when a match with its address, capture the control data CD of the transmission signal V _S. 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. Reply period above WT
, The transmission signal V _S is kept at a positive potential (+24 V), and in the control terminal device B, the two-wire type signal lines L are set to a substantially short-circuited state and the monitoring data of the monitoring data in the current mode is sent to the central control unit A. Make a reply.

Upon receiving the monitoring data, the central control unit A creates and monitors the control data CD for displaying the operating state of the load Z on the display provided in the monitoring terminal C based on the monitoring data. It is transmitted to the terminal device C. As in the case of the control terminal B, the monitoring terminal C, when the address data AD of the transmission signal V _S coincides with its own address, displays the load Z of the load Z on the display based on the control data CD of the transmission signal V _S.

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 this signal transmission, the terminal devices B and C transmit the interrupt pulse V _i shown in FIG. 7B 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 C which has made the interrupt request, and the monitoring terminal 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 an interrupt request is specified as described above, the central control unit A specifies the monitoring terminal device C which has made an interrupt request using 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. The following operation is performed in the same manner as the above-described control operation. Then, when the above control is completed, the operation returns to the standby state.

The structure of the electric shutter system based on the remote monitoring control system will be described below. The controller 1 has the function as the central control unit A of the remote monitoring and control system, and the operation unit 2 has the function as the monitoring terminal C. The system configuration is shown in FIG. First, the operating device 2
The basic configuration will be described. As shown in FIG. 2, the operation device 2 includes an opening operation switch SW _{21 for} inputting an operation for opening a shutter, a closing operation switch SW _{23 for} inputting an operation for closing a shutter, and an operation input for stopping an open / closed state of the shutter. A stop operation switch SW ₂₂ for performing the above is provided.

In terms of circuit configuration, a diode bridge DB ₁ is provided in the signal input portion to which the signal line L is connected so that the operating device 2 can be connected to the signal line L with no polarity.
And the transmission signal V _S by this diode bridge DB ₁

A return circuit 24 for returning a signal to the controller 1 with the output end of B _{1 being in} a substantially short-circuited state, a signal processing circuit 20a composed of a CPU for performing signal processing that performs a central function as a terminal device, An oscillation circuit 25a that generates a reference clock for operating the signal processing circuit 20a and a reset circuit 26 that resets the signal processing circuit 20a when the system is activated are provided.

A signal transmission method in the electric shutter system of this embodiment will be briefly described. The operating device 2 is always cyclically fed from the controller 1 to the above-mentioned bipolar (± 24
The transmission signal V _S consisting of the pulse width modulated signal of V) is transmitted. Now, when any one of the operation switches SW _{21 to} SW ₂₃ is operated, the operation device SW ₂₁ operates from the operation device 2 in synchronization with the reply period WT provided for the transmission signal V _S.
~ Sends back monitoring data indicating the operation status of SW ₂₃ . It should be noted that the description of the signal transmission in the situation where the shutter is subsequently opened and closed will be given in the description of the operation of the controller 1.

In the case of the electric shutter system of the present embodiment, in addition to the above-mentioned operation switches SW _{21 to} SW ₂₃ , a slit switch SW ₂₄ and a lower limit setting switch SW ₂₅ provided as switches for performing special functions are provided. There is. The slit switch SW ₂₄ is for opening and closing the ventilation opening provided in the shutter. As the shutter in this case, for example, a shutter having a two-layer structure in which two shutter elements are laminated in the thickness direction and each shutter element has an opening is used. Normally, the openings are kept closed by shifting the opening positions of the respective shutter elements. Then, when the slit switch SW ₂₄ is operated, the shutter element body is driven to match the positions of the openings. This allows ventilation to occur through the openings.

The lower limit setting switch SW ₂₅ is used to make settings for opening and closing the shutter in an intermediate state between the fully open state and the fully closed state. For example, a normal shutter open / close operation is performed to open / close a desired shutter. When the lower limit setting switch SW ₂₅ is turned on with, the controller 1 stores the open / closed state of the shutter when the lower limit setting switch SW ₂₅ is pressed, and when the shutter is closed from the next time,
The closing operation of the shutter is once stopped in the closed state of the shutter having the above setting. Here, when the shutter is completely closed, the shutter can be completely closed by turning on the closing operation switch SW ₂₃ again.

Incidentally, the respective operation switches SW ₂₄ , SW ₂₅
The operation status of is monitored by the controller 1 similarly to the operation switches SW _{21 to} SW ₂₃ . The operating states of the shutter based on the operations of the opening operation switch SW ₂₁ , the closing operation switch SW ₂₃ , and the slit switch SW ₂₄ are displayed by the light emitting diodes LED _{1 to} LED ₃ , respectively.

A motor control circuit 11 that controls the operation of the motor M that opens and closes the shutter 3, a power supply circuit 13 that creates a power supply for the shutter opening and closing control system from a commercial power supply (AC 100 V) separately from the signal transmission system, and detects an object. The sensor control circuit 15 that supplies power to the sensor S to operate only when necessary (when the shutter 3 is closed), and the central controller A and the control terminal B of the remote monitoring control system that perform the central functions of the controller 1. And a signal processing unit 10 that performs the above function.

In this controller 1, as an auxiliary device, an encoder E for detecting the number of rotations of the motor M,
A sensor S that detects 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 that detects that the shutter 3 is completely closed, are provided with respective outputs. In accordance with the above, the shutter opening / closing control, which will be described in detail later, and signal transmission to the operation device 2 are performed.

Now, when the monitoring data (opening operation signal) indicating that the opening operation switch SW ₂₁ has been operated is returned from the operating device 2, at this time, the signal processing section 10 captures it via the signal transmission section 12. In response to the open operation signal, FIG.
As shown in, the signal processing unit 10 gives a control signal for opening the shutter of the motor M to the motor control circuit 11. This opens the shutter.

During the opening operation of the shutter, the signal processing unit 10 detects the rotation speed of the motor M from the output of the encoder E and the shutter is completely opened due to the decrease in the rotation speed of the motor M. To detect. It should be noted that until the rotation speed of the motor M drops below a certain level, control data (in-raising signal) that causes the light-emitting diode LED ₁ for displaying the opening operation of the operating device 2 to indicate that the shutter is open is used as the operating device. 2 to turn on the light emitting diode LED ₁ .

Then, when the shutter is completely opened,
In other words, when the rotation speed of the motor M drops below a certain level,
The signal processing unit 10 controls the motor M to the motor control circuit 11.
It gives a control signal to stop the rotation. At this time, the signal
In the processing unit 10, the operation device 2 indicates that the motor M is stopped.
Control data (upper limit signal) displayed by

On the contrary, the closing operation switch SW_{twenty three}Was operated

In the same way as during the opening operation, the operation device 2 is shuffled.
Control data indicating that the
No.) is transmitted, and the light-emitting diode LED for displaying the closing operation is displayed.
₂Is lit to indicate that the closing operation is in progress.

When the shutter 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, 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 to prevent a person or an object from being caught in the shutter during the closing operation of the shutter, and the shutter is completely closed. That is, the lower limit detection switch SW
It is detected from the on / off state of 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 shutter closing operation is forcibly stopped. This prevents people or objects from being caught in the shutter. The shutter may be forcibly reversed from the closing operation to the opening operation. When such an abnormality occurs, the signal processing unit 10 sends control data to the operating device 2 to display the occurrence of the abnormality. For example, the light emitting diodes LED ₁ , L of the operating device 2
The abnormality may be displayed by giving control data for alternately turning on ED ₂ . It should be noted that another indicator may be provided in the operation device 2 for displaying an abnormality.

If the lower limit detection switch SW ₁ detects that the shutter is completely closed, the closing operation of the shutter is stopped and the light emitting diode LE of the operation device 2 is stopped.
Turn off D ₂ . In the middle opening of the shutter, stopping the operation switch SW ₂₂ has been operated (stop operation signal is returned) Sometimes, the opening and closing operation of the shutter in the controller 1 is stopped, the operating device 2 emitting diodes LED ₁ or the light emitting diode LED ₂ Control data (intermediate stop signal) for turning off the light is returned. Here, when the stop operation switch SW ₂₂ is operated during opening and closing,
You may make it perform the display which shows that a shutter has stopped in the intermediate state. For example, the stop operation performed during the opening operation may be indicated by blinking the light emitting diode LED ₁ , and the stop operation during the closing operation may be indicated by blinking the light emitting diode LED ₂ .

(Embodiment 3) Still another embodiment of the present invention will be described with reference to FIGS. 11 to 14. When a plurality of electric shutter systems (each system is called a system) are installed side by side, it may be more convenient to open and close each shutter collectively than to operate each system shutter individually. . This embodiment corresponds to such a case.
