Description

  The present invention provides a control command for controlling a load to be controlled by a transmission signal transmitted by a multiplex transmission method to a signal line in accordance with a contact signal from an external system for changing the state of the load to be controlled. It is related with the contact input terminal which outputs.

  Conventionally, an external system such as an operation device or sensor that changes the state of a load that operates according to the input of a contact signal is connected to a contact input terminal, and this load is connected to a contact output terminal. A control system that controls the state of a connected load by outputting a control command in accordance with a contact signal input from an external system by a terminal is known (see, for example, Patent Document 1).

  In this type of control system, various control modes such as individual control, group control, and pattern control are prepared in consideration of user convenience. Individual control is a method of controlling switching between an on state and an off state alternately with a single load as a control target, and group control is a method with a plurality of loads included in the same group as control targets. This is a method of performing switching control collectively and alternately with the off state. On the other hand, the pattern control is a method of collectively controlling a plurality of loads as control targets to a predetermined control state predetermined for each load.

The contact input terminal is connected to a contact signal from an external system, and detects the rising or falling of the contact signal. When the contact input terminal performs individual control or group control on the contact signal from the external system, it is assumed that the contact signal is a continuous signal. A group including a load is controlled to be in an on state, and a load or a group including a plurality of loads is controlled to be in an off state in response to the rising edge of the contact signal. On the other hand, when performing pattern control on the contact signal from the external system, the contact input terminal is based on the assumption that the contact signal is a one-pulse signal. Is controlled to a predetermined control state. That is, the operation pattern of this contact input terminal is uniquely determined in response to the contact signal and the signal change.

  By the way, according to the conventional contact input terminal, when the external system can output only a continuous signal as a contact signal due to its characteristics, there is a problem that the pattern control cannot be realized with a desired operation. Specifically, pattern control can be performed at the rising edge of the contact signal, but convenient control is required to restore the contact state. In this regard, a pulse generator may be interposed between the contact input terminal and the external system, but the system construction becomes complicated and complicated.

  Also, according to the conventional contact input terminal, if the external system can output only one pulse signal as a contact signal due to its characteristics, continuous contact make is not performed, so individual control or group control is desired. There is a problem that it cannot be realized by the operation. In this case, it may be possible to interpose a device such as a latching relay that can continuously output a pulse input between the contact input terminal and the external system, but the system construction becomes complicated and complicated. It is also possible to realize individual control or group control in the form of pattern control. However, two circuits (pattern control circuit for on state and pattern for off state, respectively) correspond to each control form. Control circuit), which may lead to waste of the circuit.

  Furthermore, according to the conventional contact input terminal, the load is controlled to be turned off in response to the rising edge of the contact signal, and the load is controlled to be turned on in response to the falling edge of the contact signal. There is an inconvenience that the reversed operation cannot be realized. In this case, it is necessary to interpose a device that outputs the contact signal from the external system in an inverted manner between the contact input terminal and the external system, which is disadvantageous in that the system construction is complicated and complicated.

(First embodiment)
FIG. 1 is a block diagram schematically showing an illumination control system according to the first embodiment of the present invention. The lighting control system includes a transmission unit 10, a relay control terminal unit (hereinafter referred to as "relay control T / U") 20, a relay 25, a remote control transformer 30, and a contact input terminal unit (contact input terminal unit). (Hereinafter referred to as “contact input T / U”) 40 and an operation terminal 60.

  The relay control T / U 20, the contact input T / U 40, and the operation terminal 60 are connected to the transmission unit 10 via a two-wire signal line. This is done through a transmission signal transmitted in a multiplex transmission manner to the line. In addition, a relay 25 is connected to the relay control T / U 20, and the lighting device 1 that is a load to be controlled is connected to the relay control T / U 20 via the relay 25.

  The lighting device 1 existing in the system (more precisely, the relay 25 to which the lighting device 1 is connected) can be uniquely specified by the load address. Specifically, a unique identifier called a load channel (Ch) is assigned to the relay control T / U 20, and a load number (Nm) is assigned to the relay 25 connected to the relay control T / U 20. A unique identifier called is assigned. A load address (Ch-Nm (see FIG. 1)) is configured by combining the load channel (Ch) and the load number (Nm).

  In the illumination control system according to the present embodiment, the transmission unit 10 illuminates the relay device via the relay control T / U 20 and the relay 25 based on the transmission signal transmitted from the contact input T / U 40 or the operation terminal 60. 1 state can be controlled. In this illumination control system, various illumination controls such as individual control, group control, and pattern control can be performed. The individual control is a method in which a single lighting device 1 is a control target and the on state and the off state are alternately controlled. Group control is a plurality of lighting devices 1 included in the same group. In this method, the on-state and the off-state are alternately and collectively switched. On the other hand, pattern control is a method of collectively controlling a plurality of lighting devices 1 as a control target to a predetermined control state (hereinafter referred to as “pattern state”) predetermined for each lighting device 1.

  The transmission unit 10 is controlled from the address information associated with the contact input T / U 40 or the operation terminal 60 based on the transmission signal from the contact input T / U 40 or the operation terminal 60 under the control of the internal processor. While specifying the target lighting device 1, the control state for the lighting device 1 is specified. Then, the transmission unit 10 transmits the address information of the lighting device 1 and its control state as a control command to the relay control T / U 20 corresponding to the lighting device 1 to be controlled.

  This address information includes an individual address, a group address or a pattern address. The individual address is information for specifying the lighting device 1 to be subjected to individual control, and the load address corresponds to this (for example, “0-1”, etc.). The group address is information for specifying a group to be subjected to group control, and corresponds to a number assigned to each preset group (for example, “G1”). The pattern address is information for specifying a pattern to be subjected to pattern control, and corresponds to a number assigned to each preset pattern (for example, “P1”).

  The transmission unit 10 holds group information indicating the load address of the lighting device 1 assigned to each group address for each group address. Therefore, when the transmission unit 10 obtains a group address from the contact input T / U 40 or the operation terminal 60, the transmission unit 10 searches the group information, and thereby a plurality of lighting devices 1 (load addresses) corresponding to the group address. Can be specified.

  Moreover, the transmission unit 10 showed the correspondence of the load address of the illuminating device 1 allocated to the pattern for every individual pattern address, and the pattern state (for example, an ON state or an OFF state) of the illuminating device 1. Holds pattern information. Therefore, when the transmission unit 10 obtains the pattern address from the contact input T / U 40 or the operation terminal 60, the transmission unit 10 searches the pattern information to thereby obtain a plurality of lighting devices 1 (load addresses) corresponding to the pattern address. And the pattern state for each lighting device 1 can be specified.

  The T / U 20 for relay control has a function as a load control terminal that controls the state of the lighting device 1 in accordance with the control state of the relay 25. The T / U 20 for relay control is a control target among relays 25 (four relays 25 in the present embodiment) connected to itself based on a transmission signal from the transmission unit 10 under the control of an internal processor. The state of the relay 25 is controlled by sending a control signal to the relay 25 corresponding to the lighting device 1. Each relay 25 is controlled by the relay control T / U 20 to turn on or off commercial alternating current from a breaker power source or the like, thereby turning the lighting device 1 into an on state (lighted state) or an off state (dark state). Control.

  The remote control transformer 30 supplies driving power to the relay control T / U 20, the relay 25, and the contact input T / U 40.

  The contact input T / U 40 and the operation terminal 60 have a function as an input terminal for outputting a control command for controlling the lighting device 1 to be controlled. The contact input T / U 40 can perform each illumination control described above via the external system 50 by connecting a contact signal from a contact (no-voltage a contact) of the external system 50. One of the features of this embodiment is the contact input T / U 40, and the detailed description thereof will be described later.

  The operation terminal device 60 is installed on an arbitrary wall surface such as a room or a manager's room, and is a terminal device that can be pushed by a user using the lighting device 1. The operation terminal 60 is provided with a plurality of operation switches 61, and address information corresponding to the lighting device 1, group, or pattern to be operated by the operation switch 61 is associated with each operation switch 61. The operation terminal 60 controls the address information associated with the operation switch 61 and the operation state of the operation switch 61 according to the operation of any of the operation switches 61 under the control of the internal processor. ON state or OFF state) is transmitted to the transmission unit 10 as a control command.

  When an individual address or a group address is associated with the operation switch 61 as address information, the lighting device 1 corresponding to the address information performs an inversion operation between the on state and the off state according to the push operation of the operation switch 61. To do. On the other hand, when a pattern address is associated with the operation switch 61 as address information, each lighting device 1 corresponding to the address information shifts to a preset pattern state according to the push operation of the operation switch 61. .

  FIG. 2 is a block diagram showing a configuration of the contact input T / U 40 according to the embodiment of the present invention. Hereinafter, the contact input T / U 40 that is one of the features of the present embodiment will be described. The contact input T / U 40 includes a control unit 40a, a transmission signal transmission / reception unit 40b, a contact input detection unit 40c, a detection circuit power supply unit 40d, an optical communication unit 40e, a storage unit 40f, and a mode switching unit 40g. It is mainly composed. The contact input T / U 40 includes a first terminal portion 41 including a pair of terminals to which a power line from the remote control transformer 30 is connected and a second terminal including a pair of terminals to which a two-wire signal line is connected. A portion 42 and a third terminal portion (connection portion) 43 including a pair of terminals to which a contact signal from the external system 50 is connected are provided (see FIG. 1). Here, a plurality of third terminal portions 43 are provided, and a plurality of external systems can be connected to the contact input T / U 40 up to the number of third terminal portions 43 installed.

  The control unit 40a has a function of comprehensively controlling the operation of the entire unit, and executes various operations described later. As the control unit 40a, a microcomputer mainly composed of a CPU, a ROM, a RAM, and an I / O interface can be used. The transmission signal transmission / reception unit 40b receives a transmission signal transmitted from the transmission unit 10 via a signal line connected to the second terminal unit 42, outputs the transmission signal to the control unit 40a, and outputs from the control unit 40a. A transmission signal corresponding to the control command is transmitted to the transmission unit 10 via the signal line.

  The contact input detection unit 40c monitors a contact signal input from an external system via the third terminal unit 43, and detects a change in the contact signal, that is, a rise of the contact signal or a fall of the contact signal. The detection circuit power supply unit 40d supplies the power supplied via the first terminal unit 41 to the detection circuit of the contact input detection unit 40c.

  The optical communication unit 40e transmits and receives information by optical communication with an address setting device (not shown) operated by a setter. Information from the address setter received by the optical communication unit 40e is output to the control unit 40a. Address information associated with the contact input T / U 40 can be acquired by communication with the address setter. Address information can be associated with the contact input T / U 40 for each of the third terminal portions 43 connected to the external system. The storage unit 40f has a function of storing various information such as address information, and a nonvolatile memory such as an EEPROM can be used.

  The mode switching unit 40g carries a switching signal for switching the operation mode to the control unit 40a. For example, a dip switch (not shown) that can be operated by a setter can be used.

  FIG. 3 is an explanatory diagram showing a transmission procedure between the contact input T / U 40 and the transmission unit 10. First, in step 1 (S1), when a change occurs in the contact signal, specifically, when the contact signal rises or the contact signal falls, this is detected by the contact input detection unit 40c. In step 2 (S2), the control unit 40a transmits an interrupt request to the transmission unit 10 via the transmission signal transmission / reception unit 40b.

  In steps 3 (S3) and 4 (S4), the transmission unit 10 made an interrupt request among the terminals (relay control T / U 20, contact input T / U 40, operation terminal 60) connected to itself. Performs processing to identify the terminal. Specifically, the transmission unit 10 specifies the upper address of the address data for terminal identification from the information included in the transmission signal transmitted as the interrupt request. Then, the transmission unit 10 transmits a terminal search by group access in which a plurality of terminals corresponding to the higher address are collectively accessed as a group. Next, in response to the transmission of the terminal search, the terminal device that made the interrupt request, that is, the contact input T / U 40 returns the remaining lower address to the transmission unit 10. Thereby, it is possible to notify the transmission unit 10 that the contact input T / U 40 has made an interrupt request.

  In step 5 (S5), when the transmission unit 10 obtains a lower address from the terminal device that made the interrupt request, that is, the contact input T / U 40, the transmission unit 10 identifies the terminal device based on this and inputs the contact input T / U 40. In response, a contact confirmation request is transmitted. In step 6 (S6), when the contact confirmation request is received, the contact input T / U 40 confirms the state of the contact signal.

  In step 7 (S7), the contact input T / U 40 determines which contact point of the external system has changed (specifically, the contact signal to be connected to which terminal unit 43 of the third terminal units 43). Contact information indicating whether or not the contact signal has changed (specifically, whether the contact signal has risen or has fallen) is acquired.

  In step 8 (S8), the contact input T / U 40 is based on the contact information, the address information associated with the third terminal unit 43 in which the contact signal has changed, and the lighting device 1 corresponding to the change in the contact signal. Are transmitted to the transmission unit 10 as a control command.

  In step 9 (S9), the transmission unit 10 transmits an interrupt termination request to the contact input T / U 40.

  Hereinafter, the processing of steps 7 and 8 by the contact input T / U 40, which is one of the features of this embodiment, will be described in detail. Here, FIG. 4 and FIG. 5 are explanatory diagrams showing the relationship between the contact signal and the control state of the relay 25.

  As shown in FIG. 4, when an individual address or a group address is set as address information of a certain third terminal unit 43, normally, the third terminal unit 43 has a contact change signal as a contact signal. An interlocking continuous signal (time T1 (for example, 1 sec or more)) is connected. In this case, the contact input T / U 40 corresponds to the rising edge of the contact signal, the address information of the third terminal unit 43, and the control state of the lighting device 1 corresponding to the change of the contact signal (basically, ON state) is output as a control command. Accordingly, the relay 25 corresponding to the address information is turned on by the transmission unit 10 and the relay control T / U 20 (that is, the corresponding lighting device 1 is controlled to be in the on state (lighted state)). On the other hand, the contact input T / U 40 corresponds to the address information of the third terminal unit 43 corresponding to the falling edge of the contact signal and the control state of the lighting device 1 corresponding to the change of the contact signal (basically off. State) is output as a control command. Along with this, the relay 25 corresponding to the address information is turned off by the transmission unit 10 and the relay control T / U 20 (that is, the corresponding lighting device 1 is controlled to be in the off state (light-off state)).

  On the other hand, as shown in FIG. 5, when a pattern address is set as address information of a certain third terminal unit 43, normally, the third terminal unit 43 has a contact change as a contact signal. Is connected to a one-pulse signal (time T2 (for example, 0.2 sec or more)). In this case, the contact input T / U 40 corresponds to the address information of the third terminal unit 43 and the control state (pattern state) of the lighting device 1 corresponding to the change of the contact signal in response to the rising of the contact signal. Output as a control command. Accordingly, the transmission unit 10 and the relay control T / U 20 turn on or off the corresponding relay 25 corresponding to the address information (that is, the corresponding lighting device 1 is controlled to the pattern state).

  As one of the features of this embodiment, the contact input T / U 40 has a pattern address set in the third terminal unit 43, that is, when pattern control is performed according to a contact signal from an external system. On the assumption that the contact signal is a one-pulse signal, the processing as described with reference to FIG. 5 is performed (operation mode corresponding to the one-pulse signal). On the other hand, the contact input T / U 40 can operate in an operation mode corresponding to a continuous signal as an operation mode different from this operation mode. In the operation mode corresponding to the continuous signal, the contact input T / U 40 assumes that the contact signal is a continuous signal, and the lighting device 1 to be controlled in response to the rise of the contact signal or the fall of the contact signal. A control command for shifting the pattern to the pattern state is output.

  Switching of the operation mode can be realized by a mode switching unit 40g that is embodied by a dip switch. For example, when an external system that can output only a continuous signal as a contact signal is connected to the third terminal unit 43 and pattern control is performed on the contact signal input to the third terminal unit 43 (that is, When the pattern address is associated with the third terminal unit 43), the contact input T / U 40 is operated in the operation mode corresponding to the continuous signal by switching the operation mode.

  FIG. 6 is a flowchart specifically showing the operation of the contact input T / U 40 in which the operation mode corresponding to the continuous signal is set.

  First, in step 10 (S10), the contact input T / U 40 determines whether or not the rising of the contact signal has been detected. If an affirmative determination is made in step 10, the process proceeds to step 11 (S11). On the other hand, if a negative determination is made in step 10, the process proceeds to step 15 (S15) described later.

  In step 11, the contact input T / U 40 indicates that the address information of the third terminal portion 43 where the contact has changed corresponds to individual control (individual address) or corresponds to group control (group address). Is determined (individual control or G control?). If an affirmative determination is made in step 11, the process proceeds to step 12 (S12). On the other hand, if a negative determination is made in step 11, the process proceeds to step 13 (S13) described later.

  In step 12, the contact input T / U 40 includes the address information (individual address or group address) of the third terminal unit 43 where the contact has changed and the control state (ON state) of the lighting device 1 corresponding to the change of the contact signal. ) As a control command (ON process).

  In step 13, the contact input T / U 40 determines whether or not the address information of the third terminal portion 43 where the contact has changed corresponds to the pattern control (pattern address) (pattern control?). . If an affirmative determination is made in step 13, the process proceeds to step 14 (S14). On the other hand, if a negative determination is made in step 13, this routine is exited.

  In step 14, the contact input T / U 40 includes the address information (pattern address) of the third terminal portion 43 where the contact has changed and the control state (basically, the lighting device 1 corresponding to the change of the contact signal. (Pattern state) is output as a control command (pattern processing).

  In step 15, the contact input T / U 40 determines whether or not the falling edge of the contact signal is detected. If an affirmative determination is made in step 15, the process proceeds to step 16 (S16). On the other hand, if a negative determination is made in step 15, this routine is exited.

  In step 16, the contact input T / U 40 indicates that the address information of the third terminal portion 43 where the contact has changed corresponds to individual control (individual address), or corresponds to group control (group address). It is determined whether or not. If an affirmative determination is made in step 16, the process proceeds to step 17 (S17). On the other hand, if a negative determination is made in step 16, the process proceeds to step 18 (S18) described later.

  In step 17, the contact input T / U 40 includes the address information (individual address or group address) of the third terminal unit 43 where the contact has changed and the control state (off state) of the lighting device 1 corresponding to the change in the contact signal. ) As a control command (off process).

  In step 18, the contact input T / U 40 determines whether or not the address information of the third terminal portion 43 where the contact has changed corresponds to the pattern control (pattern address). When an affirmative determination is made in step 18, the process proceeds to step 19 (S19). On the other hand, if a negative determination is made in step 18, the routine is exited.

  In step 19, the contact input T / U 40 indicates the address information (pattern address) of the third terminal portion 43 where the contact has changed and the control state (pattern state) of the lighting device 1 corresponding to the change of the contact signal. Output as a control command (pattern processing).

  In such a lighting control system, the transmission unit 10 responds to changes in the individual address (for example, individual address “0-1”) as the address information and the contact signal through the exchange of the transmission signal with the operation terminal 60. The control state (on state or off state) of the lighting device 1 is identified. The specified information is transmitted from the transmission unit 10 to the relay control T / U 20 of the load channel “0”, and the load number “1” connected to itself is transmitted by the relay control T / U 20 of the load channel “0”. The relay 25 is controlled according to the control state. Thereby, the illuminating device 1 of load address "0-1" is controlled to an ON state or an OFF state.

  Alternatively, the transmission unit 10 specifies a group address (for example, group “G1”) as address information and a control state (on state or off state) of the lighting device 1 corresponding to a change in the contact signal. When the address information is a group address, the transmission unit 10 refers to the group information and identifies the load address included in the group “G1” (for example, load addresses “0-1”, “1-2”). ). The specified information is transmitted from the transmission unit 10 to the relay control T / U 20 of the load channels “0” and “1”. Then, the relay 25 having the load number “1” connected thereto is controlled according to the control state by the relay control T / U 20 of the load channel “0”, and the relay control T / U of the load channel “1” is controlled. The relay 25 with the load number “2” connected to itself is controlled by U20 according to the control state. Accordingly, the lighting devices 1 corresponding to the group “G1” are collectively controlled to be switched on (or off).

  Or the transmission unit 10 specifies the pattern address (for example, pattern "P1") as address information, and the control state (pattern state) of the illuminating device 1 corresponding to the change of a contact signal. When the address information is a pattern address, the transmission unit 10 refers to the pattern information, and the load address included in the group “P1” (for example, the load address “0-3”, “1-4”), Identify individual pattern states. The specified information is transmitted from the transmission unit 10 to the relay control T / U 20 of the load channels “0” and “1”.

In the case of performing control, on the assumption that this contact signal is a continuous signal, the processing described with reference to FIG. 4 in the first embodiment is performed (operation mode corresponding to the continuous signal). On the other hand, the contact input T / U 40 can operate in an operation mode corresponding to a one-pulse signal as an operation mode different from this operation mode. In the operation mode corresponding to the one-pulse signal, the contact input T / U 40 assumes that the contact signal is a one-pulse signal, and the lighting device 1 to be controlled is controlled in the current control state (corresponding to the rising edge of the contact signal). For example, a control command for switching from the on state to the other control state (for example, the off state) is output.
