Description

The present invention relates to a relay control device for simultaneous operation for simultaneously opening and closing a plurality of electric shutters and the like installed in a building.

In the past, when operating electric shutters all at once, multiple operation switches were gathered and installed in one place, such as in a security room, for multiple electric shutters installed at various locations in a building. However, in recent years, as shown in Patent Document 1, serial data communication is used between a control panel (individual control unit 15) of an electric skylight (or shutter, etc.) and an opening / closing operation device (common operation unit 24). A method of opening and closing is employed. In addition, in a window shutter or the like installed in a general house, a control method based on serial data communication, which is standardized using a power line circuit, a dedicated line, or the like, which is called home automation (HA), is widely adopted.
JP 09-32420 A

However, a high-performance shutter control panel having a serial data communication function used in HA is expensive and cannot be said to be widespread. As shown in FIG. 2, a shutter control panel for an electric shutter that has been widely used is a simple configuration in which a main circuit is composed of two sets of electromagnetic relays for controlling forward and reverse rotation of a motor that opens and closes a shutter curtain. Therefore, a three-point push button switch for instructing opening / closing stop, a limit switch for stopping the motor at the upper and lower limit positions, a motor with an electromagnetic brake, and the like are connected thereto. In recent years, with a growing awareness of crime prevention and an aging population, it is possible to use it for general electric shutters including existing shutters, especially electric window shutters for ordinary houses, etc. There has been a need for a control device having:

The present invention has been created in order to solve these problems in view of the above-described circumstances, and in order to simultaneously operate a plurality of electric shutters, an opening / closing operation device and a shutter control panel of each electric shutter a relay control apparatus connected between, the relay control unit, the push button switches three points constituted by the stop switch closed switch and break contacts of the open switch and the make contact of the make contact, closing and stopping The first input unit to which the operation signal is input, the second input unit to which the opening / closing and stop operation signals are input as serial data from the HA operation device, and the two input signals are processed and processed through the driver circuit. A CPU that operates three sets of electromagnetic relays for opening, closing, and stopping according to the input signal, a make contact of each electromagnetic relay, and a break In combination with the three-point push button contact, a plurality of sets of output units composed of an open make contact, a close make contact, and a stop break contact are provided, and the shutter control panel is provided in the output unit. Is a relay control device for simultaneous operation of an electric shutter, characterized in that an open / close and stop operation signal corresponding to the two input signals is output to the shutter control panel.

According to the first aspect of the present invention, an open / close operation device (such as a three-point push button switch or an HA operation device capable of instructing open / close and stop operations) and a plurality of electric shutters are also used in a conventional general electric shutter. It is now possible to operate all at once simply by connecting them in between.

Next, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes an electric shutter 1, and a shutter curtain 3 guided on both left and right sides by a guide rail 2 is wound and unwound on a winding shaft 4 laid horizontally upwards to open and close the opening. It is supposed to be. The winding shaft 4 is chain-coupled with an opening / closing machine 5 (motor with electromagnetic brake), and the motor of the opening / closing machine 5 is rotated forward, reverse, and stopped by an opening / closing stop signal from a three-point push button switch 6. Yes. Here, 7 is a shutter control panel 7 that controls the operation of the switch 5, and 8 is a limit switch 8 that detects the upper and lower limit positions and stops the motor.

Next, the circuit configuration and operation of the shutter control panel 7 will be described. FIG. 2 shows a shutter control panel (electric circuit diagram) 7a, which is also a general electric shutter control circuit, an electromagnetic relay RyU for shutter opening operation (UP) and an electromagnetic relay for closing operation (DOWN). When the release switch PBU of the three-point push button switch 6a is pressed, the electromagnetic relay RyU is energized, the make contact RyU connected in parallel to the release switch PBU is closed and self-held, and at the same time between the power supply and the motor The three sets of make contacts RyU provided in FIG. 6 are closed, the electromagnetic brake is released, the motor is rotated, and the shutter curtain is opened. The motor and the electromagnetic brake are stopped when the stop switch PBS is pressed or when the fully open limit switch LSU is operated when the fully open position is reached and the circuit is cut off. The closing operation is similarly performed by operating the electromagnetic relay RyD, the closing switch PBD, and the fully closing limit switch LSD.

Next, FIG. 3 is a configuration diagram of the relay control device 10 of the present invention and main devices connected thereto. The relay control device 10 is connected to a three-point push button switch 6a, and has an input terminal TB1 to which a contact signal for opening / closing and stopping is input, a first input unit 13 including an interface circuit, and a serial including opening / closing and stopping from the HA device. A second input unit comprising an input terminal TB2 for receiving a signal and an interface circuit; a CPU for computing these input signals and operating three sets of electromagnetic relays RyU, RyD, RyS in accordance with the input signals via a driver circuit 15; Further, the electromagnetic relay is composed of three sets of output units 12, the output terminal TB3, and the like having the same configuration as the contact of the three-point push button switch by combining the make contact and break contact of the electromagnetic relay. The shutter control panel 7 is wired to the output unit 12. Next, the operation will be described. The electromagnetic relay RyU of the relay control device 10 is energized when the release switch PBU of the three-point push button switch 6 a is pressed, and the three sets of make contacts are closed, and an open signal is sent to the three shutter control panels 7 through the output unit 12. It is supposed to be. Further, the electromagnetic relay RyD closes three sets of make contacts only while pressing the closing switch PBD, and the electromagnetic relay RyS opens three sets of break contacts only while pressing the stop switch PBS. A closing signal and a stop signal are sent. In addition, when an open signal, a close signal, or a stop signal is input from the HA operation device, the three sets of electromagnetic relays operate in the same manner so that a predetermined signal for opening and closing is sent to the shutter control panel 7. It has become.

In this embodiment, the number of output units is three. However, it is needless to say that the number of output units may be four or five as long as it is two or more. Further, the relay control device 10 is configured to switch which of the first input unit 13 and the second input unit 14 is valid by switching a dip switch (not shown). Similarly, priorities can be set while both are valid. The relay control device 10 incorporates a large number of components such as a power supply, but they may have any configuration, and the description thereof is omitted. The HA operation device may be any device that can transmit open, close, and stop signals as serial data, and a detailed description thereof will be omitted. Further, although the output unit is configured by the contact of the electromagnetic relay, a semiconductor contactless relay or the like may be used. In addition to the simultaneous operation mode, when the signal including the electric shutter address is sent from the HA operation device, the operation mode in which each output unit operates individually can be arbitrarily switched with a dip switch or the like. But it ’s okay.

FIG. 4 is an example showing an expanded usage of the relay control device 10, and the output unit 12 of the first relay control device 10 connected to the opening / closing operation device such as the three-point push button switch 6 or the HA operation device 20. Among them, two sets are connected to the shutter control panel 7, and one set is connected to the first input unit of the second relay control device 10. If a shutter control panel is connected to the output unit of the second relay control device, it becomes possible to simultaneously operate a large number of electric shutters without preparing a special device. Further, the output unit of the second relay control device may be further connected to the third relay control device (first input unit), and a plurality of relay control devices may be connected to a certain relay control device. You may connect.
