Embodiment 1.
FIG. 1 is a block diagram of the load control system 50 according to the first embodiment. The load control system 50 includes an integrated operation device 1, a control device 2, a plurality of control terminals 6-1 to 6-4, and a plurality of remote control relays RRY1-1 to 4-4.

The integrated actuator 1 is composed of a personal computer or the like. The integrated actuator 1 is installed in a management room such as a guard room, for example. The integrated controller 1 and the control device 2 are connected by a LAN (Local Area Network) 10 such as Ethernet (registered trademark) which is a wired or wireless communication network. Not limited to this, the integrated operation device 1 and the control device 2 may be connected by a network. The integrated operating device 1 receives the state of the control device stored in the control device 2 via the LAN 10, displays the state of the control device on a screen or the like, and notifies the operator. The integrated operator 1 also transmits a setting signal or an operation signal to the control device 2 via the LAN 10 in response to an operation from the operator.

The control device 2 is also called a transmission processing device or a lighting controller. The control device 2 receives the setting signal and the operation signal from the integrated operation device 1 via the LAN 10. The control device 2 receives an operation signal from a wall switch or the like (not shown) or an information signal from a sensor (not shown), performs internal arithmetic processing, and then transmits a control signal to a plurality of control terminals 6-1 to 6-4. do.

The control terminals 6-1 to 6-4 are relay control terminals that control the relay. The communication side of the control device 2 and the control terminals 6-1 to 6-4 are connected by a pair of communication lines 5. A wall switch (not shown) and a sensor such as an illuminance sensor or a motion sensor (not shown) are also connected to the communication line 5. The control device 2 and the control terminals 6-1 to 6-4 communicate with each other by a pair of communication lines 5 using bipolar time division multiplexing signals. This signal is, for example, a ± 24V signal. The control device 2 transmits a control signal to the control terminals 6-1 to 6-4 via the communication line 5. Further, the control terminals 6-1 to 6-4 obtain a power source for operating the internal circuit by full-wave rectifying and stabilizing the communication signal of the communication line 5.

A common terminal is provided on the control side of the control terminals 6-1 to 6-4. The common terminal is connected to one end of the output of the remote controller transformer 3. The remote control transformer 3 supplies power to operate the remote control relays RRY1-1 to 4-4. This power supply is, for example, AC24V.

Further, each of the control terminals 6-1 to 6-4 has four control lines. Each control line is connected to one end on the input side of the remote control relays RRY1-1 to 4-4. The control line of the control terminal 6-1 is connected to the remote control relays RRY1-1 to 1-4. The control line of the control terminal 6-2 is connected to the remote control relays RRY2-1 to 2-4. The control line of the control terminal 6-3 is connected to the remote control relays RRY3-1 to 3-4. The control line of the control terminal 6-4 is connected to the remote control relays RRY4-1 to 4-4.

The other end of the input side of the remote control relays RRY1-1 to 1-4 is connected to the other end of the output of the remote control transformer 3. The load 4 is connected to the load side of the remote control relays RRY1-1 to 4-4 via the external power AC. The load 4 is, for example, a lighting fixture. The external power supply AC is not limited to an AC power supply and may be a DC power supply. The load 4 connected to the external power AC is controlled by turning the remote control relays RRY1-1 to 4-4 ON and OFF. In addition, in FIG. 1, a part of the load 4 is omitted.

The control terminals 6-1 to 6-4 and the remote control relays RRY1-1 to 4-4 constitute a plurality of terminals. The control terminals 6-1 to 6-4 output a pulse according to the control signal. The remote control relays RRY1-1 to 4-4 change the connection state between the load 4 and the external power supply AC according to the pulse. In this way, the plurality of control terminals 6-1 to 6-4 control the load 4 according to the control signal.

FIG. 2 is a diagram illustrating a communication sequence of the load control system 50 according to the first embodiment. In FIG. 2, LC1 shows a control device 2. Further, TU1 to TU4 indicate control terminals 6-1 to 6-4, respectively. First, a procedure for registering group information for collectively controlling a plurality of loads 4 shown in the communication a of FIG. 2 will be described. In the present embodiment, the case where the control terminals 6-1 to 6-4 are registered in the group 1 to be collectively controlled will be described. Here, the group number of group 1 is G1.

Each of the control terminals 6-1 to 6-4 stores its own address. As shown in the terminal information registration in FIG. 2, when the power of the load control system 50 is turned on, the control terminals 6-1 to 6-4 transmit their own addresses to the control device 2. The control device 2 that has received the addresses of the control terminals 6-1 to 6-4 stores the addresses in the internal storage device of the control device 2. Further, the control device 2 transmits a list of addresses of the control terminals 6-1 to 6-4 to the integrated controller 1.

Next, as shown in the group information registration signal of FIG. 2, the operator of the integrated controller 1 wants to collectively control from the address list of the control terminals 6-1 to 6-4 sent from the control device 2. The address is appropriately selected and transmitted to the control device 2.

The control device 2 that has received the addresses of the control terminals 6-1 to 6-4 to be collectively controlled from the integrated actuator 1 transmits to each address of the control terminals 6-1 to 6-4 that it is a batch control target. do. That is, the control device 2 transmits the group number G1 to the control terminals 6-1 to 6-4 belonging to the group 1.

Further, the control device 2 transmits the device designation information to the control terminals 6-1 to 6-4 belonging to the group 1. The device designation information is information indicating which position in the group 1 each of the control terminals 6-1 to 6-4 operates according to the control signal. In the present embodiment, the device designation information is a continuous value indicating the order in which the plurality of control terminals 6-1 to 6-4 change the connection state between the load 4 and the external power supply AC.

In the present embodiment, in the group information registration, the group number G1 and the device designation information 1 are transmitted to the control terminal 6-1. The group number G1 and the device designation information 2 are transmitted to the control terminal 6-2. The group number G1 and the device designation information 3 are transmitted to the control terminal 6-3. The group number G1 and the device designation information 4 are transmitted to the control terminal 6-4. The control terminals 6-1 to 6-4 belonging to the group 1 receive the group number and the device designation information and store them in the internal storage device.

Next, the operation of collectively controlling the load control system 50 shown in the communication b will be described. First, a group control command is transmitted from the integrated actuator 1 to the control device 2 as a control signal. A group control command is a signal for collectively operating a group.

The control device 2 broadcasts a group control command to the control terminals 6-1 to 6-4 via the communication line 5. Here, broadcast means communication in which a group number is specified without specifying a device address in the destination address area of a communication command. Here, G1 is set as the destination address of the group control command. That is, the group control command includes the group number to be controlled. Further, the group control command shall include a command to turn on the load 4 in the data area.

When each of the control terminals 6-1 to 6-4 matches the group number to be controlled received via the communication line 5 and the stored group number, the control line to the common terminal and the remote control relay is used for a certain period of time. Make it conductive. That is, each of the control terminals 6-1 to 6-4 outputs a pulse for changing the connection state between the load 4 and the external power supply AC.

As described above, when the control terminals 6-1 to 6-4 conduct the common terminal and the control line to the ON side, AC24V is supplied in a certain direction to the input side contact of the corresponding remote control relay for a certain period of time. When AC24V is supplied to the input side contacts in a certain direction for a certain period of time, the remote control relays RRY1-1 to 4-4 make the two terminals on the output side conductive. When AC24V is supplied to the input side contacts of the remote control relays RRY1-1 to 4-4 for a certain period in the direction opposite to that at the time of conduction, the two terminals on the output side are separated from each other. As described above, the remote control relays RRY1-1 to 4-4 are 1-winding latching type relays.

From the above, power is supplied to the load 4 from the external power supply AC in response to the group control command. Alternatively, the power supply to the load 4 is cut off in response to the group control command. Therefore, the control terminals 6-1 to 6-4 change the connection state between the load 4 and the power supply to control the operation of the lighting fixture or the like which is the load 4. Further, the control terminals 6-1 to 6-4 may receive a dimming command from the control device 2 and output a dimming signal to the connected lighting fixture.

Here, each of the control terminals 6-1 to 6-4 according to the present embodiment calculates the standby time according to the device designation information when the device designation information is received. The relationship between the device designation information and the standby time in the present embodiment will be described with reference to Table 1.

In the present embodiment, four control terminals 6-1 to 6-4 are shown in FIG. 1, but a maximum of 127 control terminals are connected to the communication line 5 of the load control system 50. It shall be. 1 to 127 are assigned to the control terminals as addresses, respectively. Then, the case where the addresses 12, 27, 56, and 127 are set in the group 1 by the group information registration of the integrated actuator 1 will be described in advance.

The address of the control terminal 6-1 is 12, and the device designation information is 1. The address of the control terminal 6-2 is 27, and the device designation information is 2. The address of the control terminal 6-3 is 12, and the device designation information is 3. The address of the control terminal 6-4 is 127, and the device designation information is 4.

Each standby time of the control terminals 6-1 to 6-4 is a time obtained by multiplying a value 1 smaller than the device designation information by a predetermined pulse waiting time T1. Here, the pulse waiting time is the time from when one control terminal outputs a pulse to when the next control terminal outputs a pulse.

After receiving the control signal, each of the control terminals 6-1 to 6-4 outputs a pulse for changing the connection state between the load 4 and the external power supply AC after the standby time corresponding to the device designation information of the control terminal has elapsed. .. That is, after receiving the control signal, each of the control terminals 6-1 to 6-4 performs the waiting time processing determined by the device designation information, and then drives the remote controller relay.

FIG. 3 is a diagram illustrating a pulse waiting time T1 and a pulse width T2 according to the first embodiment. FIG. 3 shows the control lines connected to the remote control relays RRY1-1 to 1-4, the remote control relays RRY2-1 to 2-4, the remote control relays RRY3-1 to 3-4, and the remote control relays RRY4-1 to 4-4 from the top. The voltage waveform is shown. When the group number of the control target notified by the group control command and the stored group number match, each of the control terminals 6-1 to 6-4 sets the pulse waiting time T1 by one less than the device designation information. After waiting, connect the common terminal and the control line for a certain period of time. That is, the control terminals 6-1 to 6-4 sequentially input pulses to the corresponding remote control relays.

Here, the pulse width T2 of the relay drive pulse is shorter than the pulse waiting time T1. Therefore, the pulses output by the control terminals 6-1 to 6-4 do not overlap. The pulse waiting time T1 is set in consideration of the operation timing variation of the control terminals 6-1 to 6-4 in addition to the time until the remote control relays RRY1-1 to 4-4 complete the conduction or release operation. .. The pulse waiting time T1 is set so that the pulses do not overlap in consideration of the variation in the clock of the microcomputer that controls the operation of the control terminals 6-1 to 6-4. The pulse waiting time T1 is, for example, several tens of milliseconds.

The pulse width T2 and the pulse waiting time T1 may be fixed values predetermined for each of the control terminals 6-1 to 6-4, or may be changed later. The pulse width T2 and the pulse waiting time T1 may be set from the integrated controller 1 or the control device 2.

FIG. 4 is a diagram illustrating a communication sequence according to the first comparative example. In the first comparative example, the control terminals 6-1 to 6-4 collectively operate the remote control relays RRY1-1 to 4-4 at the same time by the group control command. In this case, the remote control relays RRY1-1 to 4-4 may operate all at once, exceeding the current capacity that the remote control transformer 3 can supply. At this time, the remote control relays RRY1-1 to 4-4 may become inoperable.

As a countermeasure, the remote control transformer 3 is located on the input side of the control terminals 6-1 to 6-4 and the remote control relays RRY1-1 to 4-4 so that the remote control relays RRY1-1 to 4-4 have a current capacity that can operate all at once. It is conceivable to add more. However, the cost will increase and it may be difficult to secure the installation location.

FIG. 5 is a diagram illustrating a communication sequence according to the second comparative example. In the second comparative example, the control device 2 sequentially transmits control signals to the control terminals 6-1 to 6-4 in response to the group control command from the integrated actuator 1. In this case, the communication delay may accumulate by several hundred milliseconds. Therefore, the operation is slow, and it may take a long time for all the loads to operate. Further, when waiting for the response of the completion of the relay drive from one control terminal and then sending the control signal to the next control terminal, the operation may be further slowed down.

Next, the effect of this embodiment will be described. In the present embodiment, the control terminals 6-1 to 6-4 control the load 4 in order. That is, even if the control terminals 6-1 to 6-4 receive the group control command, the remote control relays RRY1-1 to 4-4 do not operate all at once. Therefore, it is sufficient that the remote controller transformer 3 can supply electric power to one control terminal at a time. Therefore, it is possible to prevent an increase in cost and an increase in size of the device by increasing the transformer capacity. Further, a large number of control terminals can be connected to one remote controller transformer 3.

Further, since each of the control terminals 6-1 to 6-4 stores the device designation information, the control device 2 needs to shift the timing and transmit the control signal to each of the control terminals 6-1 to 6-4. There is no. In the present embodiment, the control terminals 6-1 to 6-4 themselves determine the timing at which the load 4 is controlled. Therefore, the number of communications with a higher-level device can be suppressed, and the delay in operation can be improved.

In the present embodiment, the control terminal 6-4 having the last order among the control terminals 6-1 to 6-4 starts the pulse output with a delay of T1 × 3 from the reception of the control signal. Since the pulse waiting time T1 is, for example, several tens of milliseconds, the operation delay can be greatly improved as compared with the second comparative example in which the communication delay may be accumulated by several hundred milliseconds.

Further, since the control terminals 6-1 to 6-4 themselves determine the timing for controlling the load 4 with reference to the device designation information, the control device 2 can specify the group number as the address and transmit the control signal by broadcasting. Therefore, the number of communications can be reduced.

As a modification of the present embodiment, when each of the control terminals 6-1 to 6-4 receives the second control signal during the standby time corresponding to the first control signal or the output of the pulse, the first control signal is generated. The process corresponding to the control signal may be interrupted, and the load 4 may be controlled according to the second control signal. When the control terminals 6-1 to 6-4 receive different control signals during the pulse waiting time T1 or the pulse output, they operate based on the new control information. As a result, the time from the latest operation input from the control device 2 or the like to the reflection on the load 4 can be reduced.

Further, the load control system 50 of the present embodiment may have a plurality of control terminals. Further, the number of remote control relays connected to one control terminal may be one or more. This embodiment can be applied to any system including a control device 2 for transmitting a control signal and a plurality of terminals for controlling the load 4 according to the control signal.

Further, in the present embodiment, the standby time is determined according to the device designation information. Not limited to this, the order in which the control terminals 6-1 to 6-4 change the connection state between the load 4 and the power supply may be determined according to the device designation information. For example, each of the control terminals 6-1 to 6-4 may drive the relay after confirming that the control terminals in the previous order have driven the relay by referring to the device designation information. ..

In addition, the device designation information is not limited to consecutive numbers, but is different from other control terminals so that multiple control terminals 6-1 to 6-4 can output pulses in order, in other words, it is unique to each control terminal. Any value of FIG. 6 is a diagram illustrating a communication sequence according to a modified example of the first embodiment. In the modification shown in FIG. 6, the device designation information is the address of the control terminals 6-1 to 6-4. That is, each of the control terminals 6-1 to 6-4 refers to its own address and determines the waiting time. Table 2 will be used to explain the relationship between the device designation information and the standby time in this modification.

The standby time of each of the control terminals 6-1 to 6-4 is the time obtained by multiplying the value 1 smaller than the address which is the device designation information by the pulse waiting time T1. The control terminal 6-4 having the last order among the control terminals 6-1 to 6-4 starts the pulse output with a delay of T1 × 126 from the reception of the control signal. Since the pulse waiting time T1 is, for example, several tens of milliseconds, the load 4 can be controlled faster than in the second comparative example.

However, it corresponds to the case where the control terminal 6-1 is operated for 11 units, the control terminal 6-2 is for 26 units, the control terminal 6-3 is for 55 units, and the control terminal 6-1 is for 126 units. There is a waiting time. That is, it takes a considerable amount of time to complete the operation of the group 1 when the control terminals are operated in the order of 127 units. Only four control terminals 6-1 to 6-4 are registered in group 1. Therefore, a wasteful waiting time is generated between the start of the operation and the completion of the operation.

In this modification, it takes longer to start the operation and complete the operation as compared with the first embodiment. However, since the number of control terminals controlled at the same time during group control is one, the capacity of the remote controller transformer 3 can be suppressed. Further, since the addresses held in advance by the control terminals 6-1 to 6-4 are the device designation information, it is not necessary to set the device designation information later. Therefore, the control terminals 6-1 to 6-4 can be operated in order more easily than in the present embodiment.

On the other hand, in the present embodiment, even if the address numbers registered in the group are not consecutive, the time required to complete the operation is equivalent to the number of control terminals registered in the group. As can be seen from the comparison with the modification shown in FIG. 6, in the present embodiment, by using the device designation information as a continuous number, it is possible to suppress unnecessary waiting time from the start of the operation to the completion of the operation. can.

These modifications can be appropriately applied to the load control system, the terminal, and the control method of the terminal according to the following embodiments. Since the load control system, the terminal, and the control method of the terminal according to the following embodiments have much in common with the first embodiment, the differences from the first embodiment will be mainly described.

Embodiment 2.
FIG. 7 is a block diagram of the load control system 250 according to the second embodiment. In the present embodiment, the configurations of the plurality of terminals 11-1 to 11-4 are different from those in the first embodiment. Each of the plurality of terminals 11-1 to 11-4 is a terminal with a built-in relay in which a control terminal and a relay are integrated.

The terminal 11-1 includes built-in relays IRY1-1 to 1-4. The terminal 11-2 includes a built-in relay IRY2-1 to 2-4. The terminal 11-3 includes built-in relays IRY3-1 to 3-4. The terminal 11-4 includes a built-in relay IRY4-1 to 4-4. Built-in relays IRY1-1 to 4-4 are built-in power relays.

In the first embodiment, the control terminals 6-1 to 6-4 externally output the pulse for driving the relay. In this embodiment, the pulse is output to the built-in relays IRY1-1 to 4-4 inside the terminals 11-1 to 11-4.

Further, in the first embodiment, the remote control transformer 3 is used to supply the operating power of the remote control relays RRY1-1 to 4-4. On the other hand, in the present embodiment, operating power is supplied to the built-in relays IRY1-1 to 4-4 by using the internal power supply of the terminals 11-1 to 11-4. Other than this, the present embodiment is the same as the first embodiment. Therefore, the control method is basically the same.

However, the type of relay to be operated differs between the first embodiment and the present embodiment. Therefore, the pulse waiting time T1 and the pulse width T2 in the present embodiment may have optimum values different from those in the first embodiment. Further, in the first embodiment, since the internal power supply of the terminals 11-1 to 11-4 is used for the relay operation, the power supply during the relay operation is more likely to be restricted than in the first embodiment.

In the first embodiment, four remote control relays are connected to one control terminal. In other words, the remote control transformer 3 has a current capacity capable of operating four remote control relays at a time. On the other hand, in the present embodiment, if four built-in relays IRY1-1 to 4-4 are operated at the same time, the current capacity of the communication line 5 may be exceeded.

FIG. 8 is a diagram illustrating a pulse waiting time T1 and a pulse width T2 according to the second embodiment. In the present embodiment, the pulse is output twice during one cycle of the pulse waiting time T1. The pulse output during one cycle of the pulse waiting time T1 includes a first pulse and a second pulse. In one terminal, the first pulse drives two built-in relays, and the second pulse drives the remaining two built-in relays. That is, each of the plurality of terminals 11-1 to 11-4 drives the load 4 with the first pulse and then drives another load 4 with the second pulse.

In the first embodiment, each of the control terminals 6-1 to 6-4 outputs a pulse only once during the pulse waiting time T1. In comparison with this, in the present embodiment, the peak value of the current consumption can be reduced to half. Therefore, it is possible to prevent the current consumption from exceeding the current capacity of the communication line 5.

Further, in order to suppress the peak value of the current consumption, the pulse may be output three times or more during one cycle of the pulse waiting time T1. Further, in the load control system 50 of the first embodiment, when the current capacity of the remote controller transformer 3 is insufficient, the pulse may be output twice or more during one cycle of the pulse waiting time T1.
