Description

  The present invention has a control table that associates a switch of a monitoring terminal and a load controlled by the control terminal by respective addresses, and transmits a transmission signal from the monitoring terminal to the control terminal associated with the control table. The present invention relates to a switch device used as a monitoring terminal in a remote monitoring control system including a transmission unit that enables remote control of a load.

  2. Description of the Related Art Conventionally, a technique for transmitting a transmission signal including on / off information of a switch through a signal line to perform remote monitoring control of a load and opening / closing a relay for turning on / off a load by the transmission signal is known.

  As this type of remote monitoring control system, a centralized control type equipped with a monitoring terminal having a switch and a control terminal having a relay for turning on / off a load as a terminal device and a transmission unit as a center device There are things. A plurality of monitoring terminals and control terminals may be provided. The transmission unit, the monitoring terminal, and the control terminal are connected to a two-wire signal line, and the transmission unit is connected to the monitoring terminal and the control terminal using terminal addresses set individually for the monitoring terminal and the control terminal. Recognize each control terminal separately.

  The transmission unit includes a memory that stores a control table, which is a data table in which a monitoring terminal and a control terminal are associated with each other by a terminal address. The on / off information of a switch in any of the monitoring terminals is a transmission signal (time). When the transmission unit is notified using a division multiplexing transmission signal), the control terminal associated with the monitoring terminal is instructed to open and close the relay using the transmission signal by the control table. The relay is opened and closed in the control terminal that transmits and receives this instruction. Since the instruction to open and close the relay reflects the switch on / off information, a transmission unit is interposed between the monitoring terminal and the control terminal, but the transmission signal including the switch on / off information is transmitted through the signal line. As a result, the on / off state of the switch is reflected in the opening / closing of the relay.

  By the way, in general, each monitoring terminal has a switch of a plurality of circuits, and each control terminal is connected to a load of a plurality of circuits. The control table provided in the transmission unit can be associated with each switch and load circuit. In other words, for example, when a monitoring terminal has a plurality of switches, only the terminal address unique to the monitoring terminal corresponds to all the switches provided in the monitoring terminal, and the only switch actually operated Cannot be specified. Therefore, in each monitoring terminal, an operation number is assigned to each switch, and the only switch that is actually operated is used by adding the operation number after the terminal address of each monitoring terminal as the switch address. Can be specified. Similarly, in the control terminal, a load number is assigned for each load, and a load address is added to the terminal address of each control terminal after the load address. Note that one load circuit may be configured by a plurality of loads connected to one control terminal, and in this case, the terminal address of each control terminal is used as the load address.

  Further, in the control table, it is possible to associate the switches and the loads one-to-one, or one-to-many. For example, if the power to the lighting fixture as a load is turned on and off using a relay, in the transmission unit, individual control for turning on and off the lighting fixture of one circuit with one switch, and one switch Thus, it is possible to set the collective control for collectively turning on and off the lighting fixtures of a plurality of circuits. In the collective control, a range of loads to be controlled is associated with a switch, group control for collectively turning on or off the load in the range by operating one switch, and a load to be controlled There is a pattern control in which an address range and a load control state (ON or OFF) corresponding to each address are associated with a switch, and a load in the range is turned ON or OFF by operating one switch. .

  In the above-described remote monitoring control system, the transmission unit periodically transmits a transmission signal to the signal line, and a bipolar pulse width modulation signal of, for example, ± 24V is used as the transmission signal. In the monitoring terminal and the control terminal, an internal power supply is secured by full-wave rectifying the transmission signal. The transmission unit is supplied with power by a commercial power source.

  Below, operation | movement of the above-mentioned remote monitoring control system is demonstrated easily.

  The transmission unit always performs polling to periodically transmit a transmission signal whose terminal address has been changed cyclically to the signal line. The transmission signal includes a start pulse indicating the start of signal transmission, mode data indicating the signal mode, address data for transmitting a terminal address for individually calling the monitoring terminal and the control terminal, and control data for controlling the load. Bipolar including control data to be transmitted (including operation number and load number), checksum data for detecting transmission errors, and signal return period which is a time slot for receiving return signals from monitoring terminals and control terminals This signal is used.

  When a monitoring input is generated by operating a switch in any of the monitoring terminals, the monitoring terminal sends an interrupt signal synchronized with the start pulse of the transmission signal to the signal line. The monitoring terminal that has generated the interrupt signal enters a latch state in which the interrupt flag is set. On the other hand, when the transmission unit detects the interrupt signal, it transmits a transmission signal with the mode data as the search mode. When the monitoring terminal in the latched state receives the search mode transmission signal, it returns the terminal address in the signal return period, and the transmission unit that has received the terminal address returns the latched state to the monitoring terminal of the terminal address. It is confirmed that the terminal is a monitoring terminal that has generated an interrupt signal by transmitting a transmission signal for requesting and checking whether it is in a latched state. When it is confirmed that the monitoring terminal generates the interrupt signal, a transmission signal for releasing the latched state is transmitted, and the latched state of the monitoring terminal is released.

  When the transmission unit receives a request from the monitoring terminal through the above-described operation, the transmission unit requests the control terminal associated with the monitoring terminal according to the control table to control the load. Next, a transmission signal for confirming the operation state of the relay provided in the control terminal that is the control target is transmitted, and the operation state of the relay is returned from the control terminal device. The operation state of the relay received from the control terminal is confirmed in the transmission unit, and if the current operation state of the relay is off, the monitoring terminal device that has operated the switch with a transmission signal whose contents are reversed to on And a transmission signal having the same content is transmitted to the control terminal. The reason why the transmission signal for controlling the control terminal is also transmitted to the monitoring terminal is to reflect it in the display state of an indicator lamp for on / off display provided in the monitoring terminal. The control terminal that has received the transmission signal indicating the operation state returns a reception confirmation.

  In the remote monitoring control system described above, when one switch in the monitoring terminal is operated, the address (terminal address + operation number) of this switch is collated in the control table in the transmission unit, and the correspondence relationship with the switch is set. A transmission signal for instructing control of the load is transmitted from the transmission unit to the control terminal connected to the loaded load. With such an operation, switch on / off information can be reflected in the load control.

  By the way, the switch device used as the monitoring terminal in the remote monitoring control system described above includes at least one switch and an address memory for storing an address (terminal address + operation number) set for each switch in the housing. ing. An address is set in the address memory using, for example, a dedicated address setter separate from the switch device. In this example, when an address is set in the switch device, the address set by the address setting device is transferred to the switch device by wired or infrared communication, and the address is stored in the address memory.

  However, when the address is set using a dedicated address setter, since the switch device alone does not have a means for confirming the set address, when changing the layout of the operation terminal or the control terminal, It is necessary to confirm the address set in the switch device by using an address setting device, and it is troublesome to confirm the address. In addition, since the address setter is not used except when setting the address, it is stored by the administrator of the remote monitoring and control system, but if it is lost during storage, the address must be changed. In this case, it is necessary to purchase the address setting device again, which is a burden on the administrator.

Therefore, there has been proposed one in which an address setting means for setting an address stored in the address memory is added to the housing of the switch device so that the address can be set without using a dedicated address setter (for example, Patent Document 1). As address setting means, for example, one having a plurality of dip switches and setting addresses in binary numbers according to the combination of on / off states of each dip switch, and one having rotary switches and setting addresses in decimal numbers depending on the rotational position of the rotary switches There is.
JP 2006944452 A

  However, in the address setting means configured as described above, when the number of addresses used in the remote monitoring control system increases, it is necessary to increase the number of selectable addresses accordingly, and the components of the address setting means (dip switch, rotary Switch) increases. In particular, when a plurality of switches are provided in one housing, it is difficult to provide individual address setting means for each switch due to restrictions on the size of the housing. For this reason, the housing is often provided with address setting means that can set only the terminal address, and the operation number is often assigned in advance so that it cannot be changed. In the method using the DIP switch, since the address is set in binary, it is difficult for the administrator of the remote monitoring control system to understand the address as compared with the case where the address is set in decimal. There is also a problem that it is difficult to stick.

  On the other hand, the 7-segment display that digitally displays the address in two decimal digits and the selection switch that includes the up key and the down key to select the address displayed on the display are used as the address setting means. It is considered to use the address that is added every time and displayed on the display selected by the operation of the selection switch as the address for each switch. However, in this configuration, since an indicator and a selection switch are added for each switch, the components of the switch device are greatly increased, which hinders downsizing and cost reduction of the switch device.

  The present invention has been made in view of the above reasons, and can set an address without using a dedicated address setter, and even if the number of selectable addresses increases, the components of the address setting means It is an object to provide a switch device that can set an arbitrary address without increasing the number of components and that can suppress the number of constituent elements to be smaller than that of a conventional configuration.

The invention of claim 1 includes a control terminal that controls the load in accordance with the on-off of the switch by the monitoring terminal unit having a switch, the transmission signal including the off information of the switch is transmitted through the signal line, said monitoring terminal unit of the switch and the control terminals that associates with the control table transmission signal of the load and the controlled on the control terminal from the monitoring terminal device has a control table associating the respective address address to the remote monitoring and control system and a transmission unit that enables remote control of the load by transmitting, a switching device used as the monitor terminal device, and at least one of said switches, each said switch to an address memory for storing an address set for setting the address stored in said address memory A housing and means, which includes a switch handle attached to said housing, said address setting means comprises a display for displaying the address provided on the front surface of the housing, it operated to select the address and momentary-type selection switch that is, a decision switch which is operated to determine the address, normal mode transmission signal to said control terminal is transmitted in response to the operation of the switch, and the address setting is used to set addresses and a mode selector switch to switch between two modes of operation modes, said sequential switching addresses to be displayed on the display device, displayed on the display unit and the decision switch is operated every time the selection switch is operated the address stored in said address memory, said switch, said address setting mode Is also used to Itewa the selection switch, the mode selector switch is provided separately from the said switch, and provided in the inoperable covered with the switch handle is in a state in which the switch handle is mounted position of the housing It is and the switch handle has an operation panel that covers both the said mode changeover switch and operating element of the switch, that the operation panel operates the operating element of the switch by being press operation Features.

  According to this configuration, the address setting means sequentially switches the address to be displayed on the display every time the selection switch is operated, and stores the address being displayed on the display in the address memory when the determination switch is operated. The address can be set without using a dedicated address setter. In addition, since a desired address is selected from the addresses sequentially displayed on the display device, an arbitrary address can be set without increasing the components of the address setting means even if the number of selectable addresses increases. Therefore, even when a plurality of switches are provided in the housing, an arbitrary address can be set for each switch. Furthermore, since the switch is also used as the selection switch, there is an advantage that the number of components of the switch device can be reduced as compared with the case where the selection switch is provided separately from the switch.

  According to a second aspect of the present invention, in the first aspect of the invention, the address setting unit automatically switches the operation mode to the normal mode when a period in which the switch is not operated in the address setting mode continues for a predetermined no-operation time. It has a mode return function for switching automatically.

  According to this configuration, if the period in which the switch is not operated in the address setting mode continues for a non-operation time, the operation mode automatically switches to the normal mode. Therefore, if the switch device is left in the address setting mode, no operation is performed. After a while, it will switch to normal mode. Therefore, when the switch device is left in the address setting mode, it is possible to reduce the possibility that the address is erroneously changed by operating the switch for the purpose of controlling the load.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, when the address setting unit continuously operates the selection switch for a predetermined long pressing time, an address to be displayed on the display unit is displayed. It has a fast-forwarding function for switching sequentially by fast-forwarding.

  According to this configuration, even if there are a large number of selectable addresses, the address displayed on the display can be switched by fast-forwarding by long-pressing the selection switch, so that the efficiency of address setting work can be improved. In addition, the number of components of the switch device can be reduced as compared with the case where a dedicated switch for switching the address by fast-forwarding is provided separately from the selection switch.

  The present invention sequentially switches the address to be displayed on the display every time the selection switch is operated, and stores the address being displayed on the display in the address memory when the determination switch is operated. An address can be set without using it, and even if the number of selectable addresses increases, an arbitrary address can be set without increasing the number of components of the address setting means. Furthermore, since the switch is also used as the selection switch, the number of components of the switch device can be reduced as compared with the conventional configuration.

  A switch device 1 described in the following embodiment is used as a monitoring terminal in the remote monitoring control system shown in FIG. The basic configuration of the remote monitoring control system is the same as that of the remote monitoring control system described in the background art column. In the example of FIG. 2, the transmission unit is included in the components of the remote monitoring control system described in the background technology column. The master unit 21 having the functions as the control terminal and the function as the control terminal is used.

  The master unit 21 includes a relay Ry that turns on and off the power of the loads L1 to L8, and a main unit 22 to which the relay Ry is detachably connected. Furthermore, since the master unit 21 has the function of the transmission unit, it is provided in the switch device 1 by connecting the switch device 1 as a monitoring terminal using a two-wire signal line (not shown). In addition, the operation of the switch 2 (see FIG. 1) can be reflected in turning on / off of the relay Ry. In addition, the number of relay Ry circuits that can be attached to the main unit 22 of the master unit 21 is limited (here, a maximum of eight circuits), and when more load circuits are to be controlled, A slave unit (not shown) may be connected to the master unit 21 via a signal line, and the operation of the switch 2 provided in the switch device 1 may be reflected on the relay Ry of the slave unit. Since the master unit 21 can control the relay Ry by internal processing, a transmission signal from the transmission unit to the control terminal is transmitted without passing through the signal line. However, since it is necessary to use information corresponding to the address of the control terminal in order to treat it as equivalent to the slave unit even when not passing through the signal line, each relay Ry provided in the master unit 21 is switched using the control table. 2 is associated.

  Here, it is assumed that a maximum of ten slave units can be connected to the master unit 21, and each slave unit is provided with a maximum of four relays Ry. In short, a maximum of 48 relays Ry are connected to the remote monitoring and control system using the switch device 1 of the following embodiment. Therefore, assuming that the numbers 1 to 48 are assigned to the relay Ry as addresses, the relays Ry and the switches 2 having the same numbers are controlled by assigning the numbers 1 to 48 to the switches 2 of the switch device 1 as well. Assume that they are associated in a table. Further, in addition to the numbers 1 to 48, the switch 2 has an address for performing batch-off pattern control for turning off all the relays Ry in the remote monitoring control system at once and turning on all at once. Can also be assigned. That is, if the switch 2 to which the address for batch off is assigned is pressed, all the relays Ry in the remote monitoring control system are turned off.

(Embodiment)
As shown in FIG. 1, the switch device 1 according to the present embodiment includes a plurality of (here, three) switches 2 in one housing 3. The housing 3 is formed in a rectangular parallelepiped shape, and a pair of attachment pieces 4 project from both upper and lower end faces in FIG. The left and right end portions of FIG. 1 are connected to each other to form a rectangular frame-like frame body 5. In the following description, the upper, lower, left, and right in FIG.

  The frame 5 has a function similar to that of an attachment frame used when attaching the embedded wiring apparatus to a construction surface (not shown) such as a wall surface, and the switch device 1 is formed on the construction surface. The rear surface of the mounting piece 4 is fixed in contact with the construction surface around the construction hole in such a manner that the rear portion of the housing 3 is embedded in the construction hole (not shown). The attachment piece 4 is provided with a long hole 6 through which a box screw (not shown) for attaching the switch device 1 to an embedded box embedded in the construction surface is inserted. On both sides of the long hole 6, a part of a well-known clip metal fitting (not shown) for holding a construction material (not shown) such as a wall panel constituting the construction surface between the attachment pieces 4 is locked. A pin 7 is provided through the pin. Here, the housing 3 has a dimension (three module dimensions) in which three wiring appliances of unit dimensions that can be attached to a series of mounting frames standardized for embedded wiring appliances are arranged in the width direction. And is arranged on the construction surface so that the front surface is exposed.

  A portion of the front surface of the switch device 1 surrounded by the frame 5 constitutes a functional surface 9 provided with an operation element 8 that is pushed when the switch 2 is operated. The controls 8 of the switch 2 are arranged in the vertical direction. In addition to the operator 8 of the switch 2, the function surface 9 includes an indicator lamp 11 for displaying the on / off state of the relay Ry corresponding to each switch 2, an indicator 12 used for address setting described later, and mode switching A switch 13 is provided. The indicator lamp 11 is lit red when, for example, the relay Ry is on (that is, when the load is energized), and is illuminated when the relay Ry is off (that is, when the load is not energized).

  Further, the switch device 1 includes a switch handle 14 attached to the housing 3 so as to cover the functional surface 9. FIG. 1 shows a state where the switch handle 14 is removed from the housing 3. The switch handle 14 corresponds to the operation element 8 of each switch 2 and is divided into a plurality of parts (in this case, three equal parts) in the up and down direction, and the up and down direction connecting the left ends of these operation panels 15. It is attached to the housing 3 by engaging an engagement claw (not shown) provided on the back surface with the housing 3. Each operation panel 15 is supported by a connecting piece 16 so as to be able to be pushed rearward (housing 3 side). When the switch handle 14 is pushed rearward with the switch handle 14 attached to the housing 3, the operation panel 15 protrudes from the rear. The corresponding operation element 8 of the switch 2 is pushed by a contact table (not shown). The switch handle 14 is attached to the housing 3 at the normal time when the switch device 1 is used for controlling the loads L1 to L8, and the operation surface of the switch 2 is enlarged to realize excellent operability. A display window 17 is provided at a position corresponding to each indicator lamp 11 in the connecting piece 16 so that the indicator lamp 11 can be seen from the front through the display window 17 even when the switch handle 14 is attached. A decorative plate 18 (see FIG. 2) is attached around the switch handle 14 on the front surface of the housing 3.

  By the way, the switch apparatus 1 of this embodiment is memorize | stored in the address memory (not shown) which memorize | stores the address used when using as a monitoring terminal unit in a remote monitoring control system for every switch 2, and an address memory. The housing 3 is provided with address setting means 19 for setting an address.

  The address setting means 19 is operated when determining the address, the display 12 for displaying the address, the mode changeover switch 13 for switching the operation mode of the switch device 1, the selection switch operated when selecting the address, and the like. The decision switch is provided on the functional surface 9 of the housing 3. Here, the switch 2 is also used as a selection switch, and the mode switch 13 is also used as a decision switch. The display 12 is provided in association with each switch 2, but only one determination switch (mode changeover switch 13) is provided in the housing 3.

  Each of the selection switch (switch 2) and the determination switch (mode changeover switch 13) is a momentary type push button switch whose contact is turned on only while being pressed. The mode selector switch 13 alternates each time the two operation modes of the normal mode in which a transmission signal is transmitted to the control terminal according to the operation of the switch 2 and the address setting mode for setting an address are pressed. Switch. The mode switch 13 is provided at a position covered with the switch handle 14 in a state where the switch handle 14 is attached to the housing 3. Thereby, in the normal time when the switch device 1 is used for controlling the loads L1 to L8, the mode change switch 13 cannot be operated by being covered with the switch handle 14, and the mode change switch 13 is erroneously operated to set the address. Transition to the mode is prevented. In other words, the operation mode can be shifted to the address setting mode only when the switch handle 14 is detached from the housing 3, and the switch device 1 operates in the normal mode when the switch handle 14 is attached to the housing 3.

  As an example, the display 12 uses a two-digit seven-segment liquid crystal display. In addition, on the functional surface 9 of the housing 3, a correspondence display unit 20 that indicates the correspondence between the display 12 and the switch 2 is provided around each display 12. The correspondence relationship display unit 20 is drawn so as to surround each indicator 12 by a broken line and to partially indicate the corresponding switch 2. In the address setting mode, the operation mode can be displayed on the indicator lamp 11 by setting the indicator lamp 11 in a lighting state different from the normal mode (in this case, blinking red).

  In the address setting mode, the address setting means 19 having the above-described configuration sequentially switches the address to be displayed on the display unit 12 every time the selection switch (switch 2) is pressed, and the determination switch (mode change switch 13) is pressed. Then, the address being displayed on the display unit 12 is stored in the address memory. Here, since the addresses 1 to 48 are assigned as addresses to the respective switches 2 of the switch device 1, each time the switch 2 is pressed in the address setting mode, the display 12 has 1, 2, Numbers 3, ..., 48 are sequentially displayed. Further, in the present embodiment, in addition to the numbers 1 to 48, pattern OFF for collectively turning off all the relays Ry in the remote monitoring control system and turning on all at once is performed. Since an address can be assigned to the switch 2, “OF” which is a batch-off address and “on” which is a batch-on address can be selected by pressing the switch 2 in the address setting mode.

  Specifically, when “48” is displayed on the display unit 12 in the address setting mode, if the switch 2 is pressed once, “on”, which is a collective ON address, is displayed on the display unit 12, and the switch 12 If “2” is pressed, “OF”, which is a collective OFF address, is displayed on the display 12. Further, in the address setting mode, when “OF” is displayed on the display unit 12, if the switch 2 is pressed once, “−−” indicating that the address is not set (that is, not set) is displayed. If it is displayed on the display device 12 and the switch 2 is further pressed, the display on the display device 12 returns to “1”.

  Here, when the selection switch (switch 2) is continuously pressed for a predetermined long pressing time (that is, long pressing) in the address setting mode, the address setting means 19 fast-forwards the address displayed on the display unit 12. It has a fast-forward function that switches sequentially. If the switch 2 is pushed beyond the long pressing time, the address fast-forwarding continues as long as the pressing operation of the switch 2 continues. Accordingly, when the number of selectable addresses is large as in the present embodiment and the latter half of the address is set, it is necessary to display the target address on the display unit 12 by using the fast-forward function. The time can be shortened, and as a result, the work efficiency of address setting is improved. In addition, since the operation for using the fast-forward function can be performed by pressing and holding the switch 2 in the address setting mode, the switch can be used as compared with the case where a dedicated switch is provided separately from the switch 2 for the fast-forward function. The components of the device 1 can be reduced. In this embodiment, the long press time is set to 3 seconds as an example.

  Then, if the mode change switch 13 is pressed while the desired address (or “-” indicating that it has not been set) is displayed on the display 12, the displayed address is displayed on the display 12. The address is stored in the address memory as the address of the switch 2 corresponding to the device 12, and the operation mode is switched to the normal mode. In the normal mode, since the switch 2 has no function as a selection switch, the address is not changed even if the switch 2 is operated. In the present embodiment, the address of each switch 2 is displayed on the corresponding display device 12 even in the normal mode. However, the address may be displayed on the display device 12 only in the address setting mode. Note that FIG. 1 shows a state in which no address is set for any switch 2 (the display 12 indicates “−−”).

  Further, the address setting means 19 automatically switches the operation mode to the normal mode when the switch 2 is not operated for a predetermined non-operation time in the address setting mode even if the mode switch 13 is not pressed. Mode return function to switch to Thereby, for example, even if the operator leaves the place for an emergency during address setting work and the switch device 1 is left in the address setting mode, the normal mode is automatically set after the no-operation time. Therefore, it is possible to reduce the possibility that the address is erroneously changed by operating the switch device 1 without knowing that the operator is in the address setting mode. Here, when the normal mode is restored by the mode restoration function, since the determination switch (mode changeover switch 13) is not operated, the address being set on the display unit 12 is stored in the address memory. Therefore, the address of the switch 2 is not erroneously updated to the address being set. Therefore, even if the switch 2 is operated for the purpose of controlling the loads L1 to L8 and the address displayed on the display device 12 is switched while the switch device 1 is left in the address setting mode, the address is erroneously changed. It is possible to avoid setting the address memory. When returning to the normal mode by the mode return function, the address in the address memory is not updated, so the address before switching the operation mode to the address setting mode is continuously applied to the display unit 12 as well. This address will be displayed.

  Hereinafter, a method of setting an address for each switch 2 in the switch device 1 of the present embodiment will be described with reference to FIG. Here, the address of the upper switch 2 is “15”, the address of the middle switch 2 is “30”, and the address of the lower switch 2 from the state where all the addresses of the three switches 2 arranged in the vertical direction are not set. Is set to “OF” (batch off).

  When the switch device 1 is in the normal mode, the operation mode is shifted to the address setting mode by pressing the mode switch 13 once. Thereby, the indicator lamp 11 blinks red. At this time, since the addresses of all the switches 2 are not set, “-” is displayed on all the display devices 12 as shown in FIG. If a preset no-operation time (for example, 10 minutes) elapses without the switch 2 being operated in this state, the operation mode is automatically shifted to the normal mode by the mode return function.

  On the other hand, if the switch 2 is pressed in the address setting mode, the addresses displayed on the display unit 12 are sequentially switched. Therefore, as shown in FIG. ”,“ 30 ”is displayed on the middle display 12, and“ OF ”is displayed on the lower display 12. Thereafter, if the switch 2 is not operated and the non-operation time elapses, the operation mode automatically shifts to the normal mode by the mode return function. -".

  On the other hand, if the mode switch 13 is pressed once in the state of FIG. 3B, the operation mode shifts to the normal mode, and the indicator lamp 11 shifts from flashing red to lighting in red or lighting in green. At this time, the address being displayed on each display 12 is stored in the address memory as the address of the corresponding switch 2, so that even if the normal mode is entered, each display 12 is displayed as shown in FIG. “15”, “30”, and “OF” are continuously displayed.

  According to the switch device 1 of the present embodiment described above, the address setting means 19 sequentially switches the address to be displayed on the display unit 12 every time the selection switch (switch 2) is operated in the address setting mode. When the mode changeover switch 13) is operated, the address being displayed on the display device 12 is stored in the address memory, so that the address can be set without using a dedicated address setting device. In addition, since a desired address is selected from the addresses sequentially displayed on the display unit 12, an arbitrary address can be set without increasing the number of components of the address setting means 19 even if the number of selectable addresses increases. Therefore, even when a plurality of switches 2 are provided in the housing 3, it is possible to set an arbitrary address for each switch 2. Furthermore, since the switch 2 is also used as a selection switch, the number of components of the switch device 1 can be reduced as compared with the case where a selection switch is provided separately from the switch 2.

  By the way, the present invention is not limited to the three-circuit switch device 1 having three switches 2 as described above, but for example, for one circuit having one switch 2 as shown in FIG. A switch 2 having various numbers of circuits, such as for two circuits having two switches 2 as shown in FIG. 4B and for four circuits having four switches 2 as shown in FIG. It can be applied to the switch device 1 provided. In any configuration, although the display device 12 is provided for each switch 2, the switch 2 is also used as a selection switch, so that the increase in the number of components of the switch device 1 due to the provision of the address setting means 19 can be suppressed. it can.

  Next, a specific usage example of the remote monitoring control system of FIG. 2 using the switch device 1 of this embodiment as a monitoring terminal will be described. Here, as shown in FIG. 2, an example in which the remote monitoring control system is used for a building including a store space 24, a corridor 25, an office 26, and a warehouse 27 provided with a cash register counter 23 is shown.

  The master unit 21 provided with eight relays Ry is housed in a distribution board 28.
