Description

  The present invention relates to a contact output terminal using multiplex transmission, and more particularly to a technique for setting an output form of a contact signal output from a contact output terminal.

  Conventionally, a load device that operates in response to contact signal input is connected to a contact output terminal, and the contact load terminal outputs a contact signal in response to a control signal received by the contact output terminal, thereby remotely connecting the connected load device. A contact control system for controlling is used (for example, see Patent Document 1). For example, when a contact output terminal is connected to an operation switch and the load device is lighting or the like, a contact control system is known in which the contact output terminal transmits a contact signal corresponding to the operation of the operation switch to the load device. It has been.

For example, as shown in FIG. 6, such a contact control system has an output as a contact output terminal connected to a multiplex transmission master unit 102 connected to a multiplex transmission switch 101 via a multiplex transmission line L and a load device 104. The relay terminal 103 for use is connected via the multiplex transmission line L. Such a contact control system using multiplex transmission includes an output relay based on an ON instruction control signal output from the multiplex transmission base unit 102 via the multiplex transmission line L in response to the operation of the multiplex transmission switch 101. An ON instruction contact signal is output from the terminal device 103 to operate the load device 104. On the other hand, the contact control system outputs an OFF instruction contact signal from the output relay terminal 103 based on the OFF instruction control signal output from the multiplex transmission base unit 102 and stops the operation of the load device 104. The one corresponding to the so-called a contact is the mainstream.

  By the way, the contact control system may be required to output various contact signals according to the application.

  For example, depending on the application of the contact control system, an OFF instruction contact signal is output in response to an ON instruction control signal input, or an ON instruction contact signal is output from the output relay terminal 103 based on the OFF instruction control signal. In some cases, a reverse output contact (so-called b contact) is required. In this case, in the conventional contact control system, a contact output terminal dedicated for the b contact is often prepared separately. However, since it is necessary to prepare two types of contact output terminals, there is a problem that the burden on the site arrangement is large.

  Further, in the conventional contact control system, as shown in FIG. 6, an external relay 105 is provided on the output side of the output relay terminal 103, and output from the output relay terminal 103 via this external relay 105. Inverting the contact signal is also performed. However, there is a problem in that it is necessary to prepare the external relay 105 and its driving power separately and secure a space for installing them.

  Further, in the contact control system, as shown in FIG. 7, there is a case where a one-pulse contact signal needs to be output depending on the application, as in the case where a pulse contact operating device 106 is used as a load device. In this case, in the conventional contact control system, it is necessary to prepare a separate contact output terminal dedicated to the output of the one-pulse contact signal, which places a heavy burden on the site arrangement and changes the site specifications at the construction stage. In such a case, there was a problem that it was necessary to arrange again. Further, in the conventional contact control system, since the pulse time of the contact signal that can be received differs depending on the pulse contact operating device 106, it is necessary to manufacture a contact output terminal dedicated to the output of the one-pulse contact signal according to the site. There was a problem that the burden in terms of delivery time and manufacturing cost was large. Further, in the conventional contact control system, as shown in FIG. 7, a one-pulse relay that outputs a contact signal such as a one-shot timer 107 on the output side of the output relay terminal 103 is also provided. . However, there is a problem that it is necessary to separately prepare the one-pulse relay and its driving power source and to secure a space for installing them.

  Further, in the contact control system, for example, a lighting device such as a hotel room or a house entrance is turned on / off depending on the application, such as turning off the light after a predetermined time delay after a switch operation. There is a desire to delay. In this case, in the conventional contact control system, as shown in FIG. 8, a delay relay such as a delay timer 108 for delaying the output of the contact signal is provided on the output side of the output relay terminal 103. However, there is a problem in that it is necessary to separately prepare the delay relay and its driving power source and secure a space for installing these.

  Furthermore, in the contact control system, as shown in FIG. 9, the flicker function, that is, the contact signal is turned on / off alternately depending on the application, as in the case of using a status notification light or warning light 109 as a load device. There is a desire to provide a function of outputting and causing a load device to blink at predetermined time intervals. In this case, in the conventional contact control system, a flicker relay for flickering a contact signal such as the flicker timer 110 is provided on the output side of the output relay terminal 103. However, there is a problem that it is necessary to separately prepare the flicker relay and its driving power source and to secure a space for installing these.

  As described above, the conventional contact control system has a heavy burden on the site to meet the demands of various contact signal output forms according to the application, and requires an extra installation space and has a mass production effect. There was a problem that the manufacturing cost would rise because it could not be expected.

  Therefore, the present invention has been devised to solve the above-described problems, and various contact signal output modes according to the application can be used without using a plurality of terminals or external relays. It is an object of the present invention to provide a contact output terminal that can easily reduce the burden on the site and can reduce the installation area and the manufacturing cost.

  The contact output terminal according to the present invention includes setting content input means for inputting the setting content of the contact signal output form corresponding to the load device, and switching means for switching the contact signal output form based on the input setting content. By providing the above, the above-described problems are solved.

  According to the contact output terminal according to the present invention, it is not necessary to use a plurality of terminals, external relays, etc. in order to meet the demands for various contact signal output forms according to the application. The burden can be greatly reduced and the installation area can be reduced. In addition, according to the contact output terminal according to the present invention, the mass production effect can be greatly increased, so that the manufacturing cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  This embodiment is a contact control system that controls a load device by outputting a contact signal using multiple transmission lines. In particular, in this contact control system, an output relay terminal as a contact output terminal is provided with a contact signal output mode setting and switching means.

[First Embodiment]
As shown in FIG. 1, the contact control system includes a multiplex transmission switch 11 that accepts user operations, a multiplex transmission master 12 that performs signal transfer control, and an output relay terminal 13 as a contact output terminal. And are connected via a multiplex transmission line L.

  For example, when the load device to be controlled is a lighting fixture, the multiplex transmission switch 11 receives an operation of a user who uses the load appliance such as a switch provided on a wall surface to control the lighting fixture. It is a device. The operation information received by the multiplex transmission switch 11 is output to the multiplex transmission master 12 via the multiplex transmission line L.

  The multiplex transmission base unit 12 receives various terminals connected to the multiplex transmission line L, such as an output relay terminal 13 and an input relay terminal (not shown), and addresses uniquely assigned to the load devices 14a, 14b, and 14c. Based on this address, transfer control of signals transmitted through the multiplex transmission line L is performed. Based on the operation information output from the multiplex transmission switch 11 via the multiplex transmission line L, the multiplex transmission master unit 12 outputs an ON instruction or an OFF instruction control signal via the multiplex transmission line L. 13 is output.

  The output relay terminal 13 is connected to load devices 14a, 14b, and 14c that operate in response to input of contact signals. The output relay terminal 13 connects the load devices 14a, 14b, and 14c under the control of an internal processor based on a control signal output from the multiplex transmission master 12 via the multiplex transmission line L. A contact signal for control is output.

  Here, for convenience of explanation, the load device 14a is a device corresponding to a normal a contact, and the load device 14b is a pulse contact operation device that operates based on a contact signal of a predetermined pulse time. Assume that 14c is a lighting fixture that can be turned off with a predetermined delay after the switch operation. A contact-compatible device is a device that outputs an ON signal or an OFF signal to the output relay terminal 13, and the output relay terminal 13 may output an ON or OFF contact signal. On the other hand, when the device for b contact described later outputs an ON signal or an OFF signal to the output relay terminal device 13, the output relay terminal device 13 outputs the opposite OFF or ON contact signal. It is a device that must output.

  In such a contact control system, the output relay terminal 13 is under the control of the internal processor so that the output form of the contact signal can be changed in accordance with each of the load devices 14a, 14b and 14c. In addition, the output form of the contact signal can be set and switched. Here, for example, as shown in FIG. 2, the output relay terminal 13 is configured to set the output form of the contact signal on the surface of the housing by a physical operation of a setter such as an on-site contractor. A switching operator 15 is provided.

  Note that the setting contents of the contact signal output form include a mode for outputting a contact signal corresponding to the a contact, a mode for outputting a contact signal corresponding to the b contact, and outputting a one-pulse contact signal of a predetermined pulse time. Any one of a mode, a mode in which the contact signal is output after being delayed by a predetermined time, a mode in which the contact signal is output in a flicker at a predetermined time interval, or a mode in which these are combined.

  Specifically, it is preferable to provide a switch 15a, a rotary knob 15b, or the like as the switching operator 15. The switch 15a is configured to be switchable to, for example, a mode for outputting a contact signal corresponding to a contact, a mode for outputting a contact signal corresponding to a b contact, and a mode for outputting a one-pulse contact signal. The rotary knob 15b is configured to be able to switch between a delay time when the contact signal is output after being delayed by a predetermined time and a pulse time when the one-pulse contact signal is output by rotating. Note that the specific configuration of the switching operator 15 is not limited to this, and an arbitrary one can be applied as long as it is physically operable, such as a push button.

  Such a switching operator 15 corresponds to, for example, each output terminal so that the output form can be switched for each output terminal when there are a plurality of contact signal output terminals for connecting a plurality of load devices. Provided. Therefore, the setting person operates the switch 15a to output the contact signal corresponding to the a contact for the switching operation element 15 corresponding to the output terminal to which the load device 14a that is the device corresponding to the a contact is connected. Should be set. In addition, the setter sets the switching operator 15 corresponding to the output terminal to which the load device 14b, which is a pulse contact operating device, is connected to a mode for outputting a one-pulse contact signal by operating the switch 15a. The desired value may be set by operating the rotary knob 15b. Furthermore, the setting person operates the switch 15a for the switching operator 15 corresponding to the output terminal to which the load device 14c that needs to output the contact signal delayed by a predetermined time is operated. May be set to a mode in which either a contact signal corresponding to a contact, a contact signal corresponding to a b contact, or a one-pulse contact signal is output, and a desired delay time may be set by operating the rotary knob 15b.

  The output relay terminal 13 provided with such a switching operator 15 captures the setting contents of the switching operator 15 into an internal processor, and switches the output form of the contact signal under the control of the processor.

  Therefore, the setter can easily set the output form of the contact signal only by operating the switching operation element 15 according to the load device to be connected during construction on site.

  In FIG. 2, the switching operator 15 for switching the contact signal so as to output the flicker at a predetermined time interval is not shown, but the output relay terminal 13 is also provided with such a switching operator 15. Needless to say. In particular, the switching operation element 15 for switching the contact signal so as to output the flicker at predetermined time intervals may be provided in an input relay terminal (not shown), but is preferably provided in the output relay terminal 13. This is because when the switching operation element 15 is provided in the input relay terminal, a contact signal instructing to that effect is transmitted to the output relay terminal 13 at every lighting of the blinking operation of the load device. This is because the amount of data transmitted through the multiplex transmission line L increases.

  As described above in detail, in the contact control system according to the first embodiment of the present invention, the output relay terminal device 13 sets the setting contents of the contact signal output form according to the load devices 14a, 14b, and 14c. Input to the processor, and under the control of the processor, the output form of the contact signal is switched based on the input setting contents. In particular, in this contact control system, a switching operation element 15 is provided on the surface of the housing of the output relay terminal 13 so that the output form of the contact signal can be set by a physical operation of the setter. In order to meet the demands of various contact signal output forms according to the application by switching the contact signal output forms under the control of the processor that takes in the setting contents of the switching operation element 15, a plurality of terminals Since there is no need to use an external relay or the like, it is possible to greatly reduce the burden of on-site arrangements and to reduce the installation area. Further, in this contact control system, the mass production effect can be greatly increased, so that the manufacturing cost can be reduced.

[Second Embodiment]
Next, a contact control system shown as a second embodiment of the present invention will be described.

  This contact control system switches the output form of a contact signal output from an output relay terminal as a contact output terminal via wireless communication or wired communication. Accordingly, in the description of the second embodiment, the same components as those in the description of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 3, the contact control system includes a multiplex transmission switch 11 that accepts user operations, a multiplex transmission master 12 that performs signal transfer control, and an output relay terminal 21 as a contact output terminal. And are connected via a multiplex transmission line L.

  The output relay terminal 21 is connected to the load devices 14a, 14b, 14c, and 14d that operate in response to the input of the contact signal, and the control signal output from the multiplex transmission master 12 via the multiplex transmission line L. Based on the above, a contact signal for controlling the load devices 14a, 14b, 14c, and 14d is output under the control of the internal processor. Here, for convenience of explanation, the load device 14a is a device corresponding to a normal a contact, and the load device 14b is a pulse contact operation device that operates based on a contact signal of a predetermined pulse time. 14c is a lighting fixture that can be turned off with a predetermined time delay after the switch operation, and the load device 14d is a warning light that blinks at predetermined time intervals.

  In such a contact control system, the output relay terminal 21 has an external setter 22 operated by a setter such as a construction contractor on site, and a transmission / reception unit 21a that transmits and receives signals. Wireless communication such as infrared communication or wired communication via a predetermined transmission line can be performed. Then, the output relay terminal 21 receives the setting signal transmitted from the setting device 22 via the transmission / reception unit 21a, and according to each of the load devices 14a, 14b, 14c, and 14d based on the setting signal. The contact signal output form is switched under the control of the internal processor so that the contact signal output form can be changed.

  Specifically, for example, as shown in FIG. 4, the setting unit 22 sets the output form of the contact signal for each address corresponding to each output terminal of the contact signal in the output relay terminal 21 on the display unit. To display the setting screen. The specific configuration of the setting screen is not limited to this, and any configuration can be applied as long as necessary items can be set.

  If the setting person sets the address corresponding to the output terminal to which the load device 14a, which is the device corresponding to the a contact, is connected, by operating the setting device 22 to the mode for outputting the contact signal corresponding to the a contact. Good. Further, the setter operates the setting device 22 for the address corresponding to the output terminal to which the load device 14b, which is a pulse contact operating device that operates based on a contact signal with a pulse time of 1 second, is connected. The mode may be set to output a one-pulse contact signal and the pulse time may be set to 1 second. Further, the setter operates the setting unit 22 for the address corresponding to the output terminal to which the load device 14c to which the contact signal corresponding to the contact “a” of OFF instruction needs to be output after being delayed for 30 seconds. And a mode for outputting a contact signal corresponding to the contact a, setting that the contact signal to be delayed is an OFF instruction, and setting the delay time to 30 seconds. Furthermore, the setting person operates the setting device 22 to output a flicker signal for the address corresponding to the output terminal to which the load device 14d, which is a warning light that blinks at intervals of 2 seconds, is connected. And a time interval for alternately outputting contact signals on / off may be set to 2 seconds.

  When a setting signal indicating the content set via such a setting screen is transmitted from the setting device 22, the output relay terminal device 21 receives the setting signal via the transmission / reception unit 21 a, and the internal processor Into. Then, the output relay terminal 21 switches the output form of the contact signal based on the fetched setting signal under the control of the processor.

  Therefore, the setting person can easily set the output form of the contact signal only by operating the setting device 22 according to the load device to be connected and transmitting the setting signal during construction on site.

  As described above in detail, in the contact control system according to the second embodiment of the present invention, the setting contents of the contact signal output form set by the setter operating the external setting device 22 are set. The setting signal shown can be transmitted to the output relay terminal 21 via wireless communication or wired communication to directly set the output form of the contact signal. Therefore, in this contact control system, it is not necessary to use multiple terminals or external relays to meet the demands for various contact signal output formats depending on the application, greatly increasing the burden of on-site arrangements. It is possible to reduce the installation area and the installation area. Further, in this contact control system, the mass production effect can be greatly increased, so that the manufacturing cost can be reduced.

[Third Embodiment]
Finally, a contact control system shown as a third embodiment of the present invention will be described.

  This contact control system switches the output form of a contact signal output from an output relay terminal as a contact output terminal by communication via multiple transmission lines. Therefore, in the description of the third embodiment, the same reference numerals are given to the same configurations as those in the description of the first embodiment and the second embodiment, and the detailed description thereof is omitted.

  As shown in FIG. 5, the contact control system includes a multiplex transmission switch 11 that accepts user operations, a multiplex transmission master 12 that performs signal transfer control, and an output relay terminal 31 as a contact output terminal. And are connected via a multiplex transmission line L.

  The output relay terminal 31 is connected to the load devices 14a, 14b, 14c, and 14d that operate in response to the input of the contact signal, and the control signal output from the multiplex transmission master unit 12 through the multiplex transmission line L. Based on the above, a contact signal for controlling the load devices 14a, 14b, 14c, and 14d is output under the control of the internal processor.

  In such a contact control system, the output relay terminal 31 is connected to an external setter 32 operated by a setter such as a construction contractor on site via a multiplex transmission line L, and a transmission / reception unit (not shown) is provided. The setting signal transmitted from the setting device 32 is received, and the output form of the contact signal can be changed according to each of the load devices 14a, 14b, 14c, and 14d based on the setting signal. In addition, the contact signal output form is switched under the control of the internal processor.

  Specifically, the setting device 32 displays a setting screen similar to the setting screen previously shown in FIG. 4 on the display unit, and multiplexes setting signals indicating the contents set under the operation of the setter. The data is transmitted to the output relay terminal 31 via the transmission line L. In response to this, the output relay terminal 31 takes the received setting signal into an internal processor, and switches the output form of the contact signal based on the taken setting signal under the control of the processor.

  The output relay terminal 31 is assigned a terminal number unique to the output relay terminal 31 in advance, and a terminal number is assigned to each output terminal of the contact signal. 32 stores these terminal numbers and terminal numbers in a memory or the like so that they can be referred to. In the contact control system, when the setter operates the setting device 32, the multiplex transmission master 12 is designated by specifying a unique terminal device number and terminal number for the output relay terminal device 31 to be set. It distinguishes from other output relay terminals connected to the multiplex transmission line L, and transmits a setting signal to the designated output relay terminal 31.

  Therefore, the setting person can easily set the output form of the contact signal only by operating the setting device 32 and transmitting the setting signal according to the load device to be connected at the time of construction on site. In particular, since the multiplex transmission line L is laid in the entire building, for example, the setter can confirm the desired setting and setting contents from a remote location without going to the vicinity of the output relay terminal 31 to be set. Can do.

  In the contact control system, a web page on which the setting contents of all output relay terminals connected to the multiplex transmission line L are connected to a plurality of multiplex transmission masters (not shown). Can be created by the web page creation device, and the web page can be managed using a predetermined management terminal (not shown). Thereby, in a contact control system, a setting person browses a web page using a remote management terminal, and confirms and updates the setting contents of a desired output relay terminal as necessary. it can.

  As described above in detail, in the contact control system according to the third embodiment of the present invention, the contact set by the setter operating the external setting device 32 connected to the multiple transmission line L. A setting signal indicating the setting contents of the signal output form can be transmitted to the output relay terminal 31 to remotely set the contact signal output form. Therefore, in this contact control system, it is not necessary to use multiple terminals or external relays in order to meet the demands for various contact signal output formats depending on the application, greatly increasing the burden of on-site arrangements. It is possible to reduce the installation area and the installation area. Further, in this contact control system, the mass production effect can be greatly increased, so that the manufacturing cost can be reduced.
