[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring and control system, and more particularly to a remote monitoring and control system having a terminal for a heat ray sensor for controlling a load according to the presence or absence of a person in a detection area. is there.

[0002]

2. Description of the Related Art Conventionally, a remote monitoring control system having a configuration shown in FIG.
0-108279). In the figure, one control terminal 32 can individually control up to four loads L. In other words, in addition to the control address individually given to each control terminal 32, a 2-bit load number is set in each control terminal 32, and which load L is controlled by specifying the load number is determined. You can choose. The operation terminal 31 has an operation address and a load number set in the same manner as the control terminal 32, and can connect up to four operation switches S0.

[0003] A plurality of operation terminals 31 and control terminals 32 are provided, respectively, and are connected to the transmission control device 30 via a two-wire signal line Ls. Each operation terminal 31 is set with an individual operation address, and each control terminal 32 is set with an individual control address. The operation terminal 31 and the control terminal 32 are individually recognized using the address.

[0004] The transmission control device 30 controls the signal line Ls
The transmission signal Vs of the format shown in FIG. That is, the synchronization signal SY indicating the start of signal transmission, the mode data MD indicating the mode of the transmission signal Vs, the address data AD (including the load number) for separately calling the operation terminal 31 and the control terminal 32, and the load L. The control data CD to be controlled, the checksum data CS for detecting a transmission error, the signal return period W which is a time slot for receiving a return signal from the operation terminal 31 or the control terminal 32.
This is a bipolar (± 24 V) time-division multiplex signal composed of T, and data is transmitted by pulse width modulation (FIG. 17B). In each operation terminal device 31 and each control terminal device 32, when the address data AD transmitted by the transmission signal Vs received via the signal line Ls matches the preset operation address or control address, the transmission signal While taking in the control data CD from Vs, the monitoring data is returned as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via an appropriate low impedance) during the signal return period WT of the transmission signal Vs.

[0005] A desired operation terminal 3 is transmitted from the transmission control device 30.
1 or when transmitting data to the control terminal 32, a transmission signal Vs in which the mode data MD is set to the control mode and the operation address or control address of the operation terminal 31 or the control terminal 32 is set to the address data AD. When the transmission signal Vs is transmitted to the signal line Ls, the operation terminal 31 or the control terminal 3 which matches the address data AD is transmitted.
2 receives the control data CD and returns the monitoring data during the signal return period WT. In the transmission control device 30, the control data CD is transmitted to the desired operation terminal 3 based on the relationship between the transmitted control data CD and the monitoring data received during the signal return period WT.
1 or the transmission to the control terminal 32 is confirmed.
The control terminal 32 outputs a load control signal for controlling the load L in accordance with the received control data CD, and the operation terminal 31 outputs a monitoring signal for displaying an operation confirmation of the load L in accordance with the received control data CD. I do.

On the other hand, the transmission control device 30 normally transmits the transmission signal Vs in which the mode data MD is in the dummy mode at regular time intervals.
When trying to transmit some information to 0,
An interrupt signal as shown in FIG. 17C is generated in synchronization with the synchronization signal SY of the transmission signal Vs in the dummy mode. At this time, the operation terminal 31 sets an interrupt flag to prepare for the subsequent information exchange with the transmission control device 30. Transmission control device 30
When the interrupt signal is received, the transmission signal is transmitted while the mode data MD is set to the interrupt polling mode and the upper half of the address data AD (the upper 4 bits when the address data AD is 8 bits) is sequentially increased. And
In the operation terminal 31 that has generated the interrupt signal, when the upper 4 bits of the address data AD of the transmission signal in the interrupt polling mode match the upper 4 bits of the operation address set in the operation terminal 31, During the signal return period WT, the lower half bits of the operation address are transmitted to the transmission control device 30.
Return to. As described above, since the transmission control device 30 collectively searches for 16 operation terminals 31 that have generated the interrupt signal, the operation terminal 31 can be found in a relatively short time. When the transmission control device 30 acquires the operation address of the operation terminal device 31 that has generated the interrupt signal in this way, the mode data MD is set to the monitoring mode, and the transmission signal having the acquired address data AD is transmitted to the signal line Ls. In response to this transmission signal, the operation terminal device 31 returns the information to be transmitted in the signal return period WT. Finally, the transmission control device 30 sends a signal instructing an interrupt reset to the operation terminal device 31 that has generated the interrupt signal, and releases the interrupt flag of the operation terminal device 31. As described above, information transmission from the operation terminal device 31 to the transmission control device 30 is performed by four signal transmissions from the transmission control device 30 to the operation terminal device 31 (dummy mode, interrupt polling mode, monitoring mode, Reset). When the transmission control device 30 wants to know the desired operating state of the control terminal 32, it is only necessary to transmit a transmission signal using the mode data MD as monitoring data.

The above operation will be briefly summarized. First, when there is an operation input from the switch S0 to the operation terminal 31, monitoring data corresponding to the operation input is transmitted to the transmission control device 30.
When the transmission control device 30 transmits the control data CD to the control terminal device 32, the control terminal device 32 outputs a load control signal to control the load L. Here, the control terminal 32
Receives a load monitoring input, returns monitoring data corresponding to the load monitoring input to the transmission control device 30, and transmits the returned monitoring data to the operation terminal 31. The operation terminal 31 outputs a monitoring signal according to the transmission signal. The monitoring output is usually the operation confirmation light consisting of a light emitting diode.
Used for turning off lights.

In the illustrated remote monitoring and control system, a dimming control terminal 33 is connected to a signal line Ls, which controls the light output of a lighting load as a load, and is controlled by a transmission signal Vs. When an increase or a decrease in the light output of the lighting load is instructed, the light output is changed over time, and when a stop is instructed by another transmission signal, the change in the light output is stopped. The dimming control terminal 33 is associated with a dimming operation terminal 38, and the dimming operation terminal 38 is provided with an operation unit for instructing an increase or decrease in the light output of the load L. When the operation unit is pressed, the light output is changed in the dimming control terminal 33 by the transmission signal. When the operation of the operation unit is stopped (that is, when the pressing operation is stopped), the dimming control terminal 33 stops the change of the light output by another transmission signal. The dimming operation terminal 38 is also provided with an operation unit for turning on and off the load L. When the load L is turned off by operating the operation unit, the light output at the previous time when the load L is turned on next time is reduced. The load L is turned on. The previous light output is stored in each dimming control terminal 33.

In this type of remote monitoring and control system, the transmission control device 30 manages the correspondence between addresses on the operation side and the control side. By associating a plurality of control addresses, a plurality of loads L can be controlled collectively by one switch S0. Such collective control includes group control and pattern control. In group control, a plurality of loads are controlled to the same control state, and in pattern control, a plurality of loads are controlled to a preset control state. The collective control operation terminal 39 for performing group control and pattern control uses an operation address defined as collective control, but other configurations are the same as those of other operation terminals. In the illustrated example, the dimming operation terminal 3 is used.
A collective control operation terminal 39 of the same type as that of 8 is provided, and the collective control operation terminal 39 can simultaneously control a plurality of loads L.

As a terminal used in this type of remote monitoring and control system, a heat ray sensor detects a heat ray radiated from a human body and monitors a human body detection signal output according to the presence or absence of a person in a detection area. When a person (movement of a person) in the detection area is detected by the heat ray sensor, monitoring data for operating the load (for example, turning on a lighting load) is returned to the transmission control device 30 and detected by the heat ray sensor. The monitoring area is returned to the transmission control device 30 such that the load is stopped (for example, the lighting load is turned off) when a predetermined operation holding time elapses after no more people are detected in the area. Terminal for heat ray sensor 4 that enables load control according to the presence or absence of a person inside

When a human body detection signal is input by being detected by 0 or the heat ray sensor of the heat ray sensor slave 41, the heat ray sensor terminal 40 outputs monitoring data (data indicating that the output is on) corresponding to the human body detection signal. When the transmission control device 30 transmits the control data to the relay control terminal 36 according to the address correspondence,
The relay control terminal 36 turns on the remote control relay 35 to turn on the illumination load L. Then, when the operation holding time has elapsed, the heat ray sensor terminal 40 returns corresponding monitoring data (data indicating that the output is off) to the transmission control device 30, and the transmission control device 30 When the control data is transmitted to the terminal 36, the relay control terminal 36 turns off the remote control relay 35 and turns off the lighting load L. Here, the address of the blinking switch Sa of the operation terminal 31 is also associated with the address of the relay control terminal 36, and the lighting load L is forcibly turned on / off by operating the blinking switch Sa. be able to.

Reference numeral 1 denotes a type connected by a dedicated signal line, and is usually provided on a distribution board. An illuminance sensor 42 for detecting ambient illuminance can be connected to the heat ray sensor terminal 40. If the ambient illuminance detected by the illuminance sensor 42 is higher than a predetermined value, a human body detection signal is input. However, the monitoring data (data indicating that the output is on) is not returned to the transmission control device 30, and the monitoring data is transmitted and controlled only when the ambient illuminance is lower than a predetermined value and a human body detection signal is input. It is returned to the device 30. Here, reference numeral 37 denotes a control terminal with a built-in relay, in which the relay control terminal 36 and the remote control relay 35 in the above system configuration example are integrated.

By the way, in recent years, the comfort of the lighting environment and the energy saving have been demanded. In the system for controlling the lighting load L by using the terminal 40 for the heat ray sensor as described above. Also, as shown in FIG. 20, when there is a person in the detection area, the lighting load L is fully lit at 100% of the rated value, and when there is no person, the rated load is 3%.
By dimming and lighting at a dimming level of about 0%,
There is a demand for energy saving while realizing a more comfortable lighting environment than turning off the light when no one is present.

However, the conventional heat ray sensor terminal 40 outputs data indicating on / off of the output as monitoring data, and individually controls to turn on / off one illumination load L, or a plurality of controls. This is for performing group control for turning on / off the lighting load L collectively. As described above, the lighting load L is turned on at a dimming level different from when a person is detected and after an operation holding time has elapsed. Was difficult. That is, the dimming control terminal 33 for dimming control of the lighting load L outputs a dimming signal for setting a desired dimming level according to the control data to the lighting load (an inverter type capable of continuous dimming). (A fluorescent lighting device) L. On the other hand, in the lighting load L including the inverter-type fluorescent lamp lighting device, the dimming operation is performed when the dimming output from the dimming control terminal 33 is on, and is fully illuminated when the dimming output is off.

For this reason, in the system using the above-mentioned conventional heat ray sensor terminal 40, as shown in FIG. 21, a period from when a human enters the detection area and a human body detection signal is output until the operation holding time elapses. The dimming output of the dimming control terminal 33 is turned on,
At other times, the dimming output is turned off, so that the lighting load L is fully lit when no person is present, and the lighting load L is dimmed and lit when a person is detected, which is completely opposite to the desired operation described above. Operation. That is, in order to realize the desired operation, as shown in FIG. 22, the control terminal for dimming is performed between the time when a person enters the detection area and the human body detection signal is output and the operation holding time elapses. The dimming output of the heater 33 must be turned off, and at other times, the dimming output must be turned on. Therefore, the desired operation is performed using the conventional heat ray sensor terminal 40. Had to have a system configuration as shown in FIG.

First, when a person enters the detection area and is detected by the hot-wire sensor of the hot-wire sensor slave 41 and a human body detection signal is input to the hot-wire sensor terminal 40, monitoring data corresponding thereto is transmitted to the transmission control device 30. When the transmission control device 30 that has returned and received the monitoring data transmits the control data to the relay control terminal device 36 in accordance with the address correspondence, the relay control terminal device 36 turns on the main circuit of the remote control relay 35 '. At this time, as shown in FIG.
The auxiliary contact 5 'is switched from the normally open (NO) side to the normally closed (NC) side, and this contact signal is input to the contact monitoring terminal 43. The contact monitoring terminal 43, to which the contact signal has been input, transmits monitoring data corresponding to the contact signal to the transmission control device 30.
When the transmission control device 30 that has received the monitoring data transmits the control data to the dimming control terminal 33 in accordance with the address correspondence, the dimming control terminal 33 is turned on. By turning off the output, the lighting load L
All lights up. Here, the control data transmitted from the transmission control device 30 to the dimming control terminal 33 is pattern control data for turning on a plurality of lighting loads L all at once. Then, when the operation holding time has elapsed, the heat ray sensor terminal 40 transmits monitoring data corresponding thereto to the transmission control device 3.
0, and the transmission control device 30
6 transmits the control data to the relay control terminal 36.

At this time, the auxiliary contact of the remote control relay 35 'is switched from the normally closed (NC) side to the normally open (NO) side, and this contact signal is input to the contact monitoring terminal 43. The contact monitoring terminal 43 to which the contact signal has been input returns monitoring data corresponding to the contact signal to the transmission control device 30, and the transmission control device 30 that has received the monitoring data transmits the dimming control terminal in accordance with the address correspondence. When the control data is transmitted to 33, the dimming control terminal 33 turns on the dimming output that has been turned off so that the lighting load L is dimmed and lit. Here, the control data transmitted from the transmission control device 30 to the dimming control terminal 33 is pattern control data for dimming and lighting a plurality of lighting loads L at the same or different dimming levels simultaneously.

According to the above system configuration, when no person is in the detection area, the lighting load L is dimmed and lit at a low dimming level, and when the person enters the detection area, the lighting load L is fully lit. It is possible to realize control such that the lighting load L is again light-controlled and lit at the above-mentioned light control level after the operation holding time elapses after the person has left the detection area.

However, in order to construct the above-mentioned system, it is necessary to add a large number of terminals to the basic configuration, and the system configuration becomes complicated, which leads to an increase in cost and a trouble in construction. .

In the heat ray sensor terminal 1 of the present embodiment, two or three addresses can be set in the address storage unit 5, and each horizontal row in the screen W shown in FIG. It corresponds to the address. Here, any of the above three types of addresses can be set as the first stage address,
When the pattern control address is set, it becomes an address used when sending monitoring data when a human body detection signal is input. In addition, a pattern control address can be set as the second-stage address, and when the pattern control address is set, it becomes an address used when sending monitoring data when the operation holding time has elapsed. However,
Only when the individual control address or the group control address is set in the first row as shown in FIG. 5, the individual control address corresponding to the hot-wire sensor on / off switch Sb of the operation terminal 31 is set. It becomes possible. In the third-stage address, only the individual control address corresponding to the hot-wire sensor on / off switch Sb of the operation terminal device 31 can be set.

Next, the procedure for setting address data in the hot-wire sensor terminal 1 using the wireless address setting device will be described with reference to the flowcharts of FIGS. First, in a state where the light emitting / receiving section of the wireless address setting device is close to the light transmitting window 1e of the terminal for heat ray sensor 1, the content of the address storage section 5 is confirmed by the wireless address setting device by an optical wireless signal (S1). A desired address is input using a numeric keypad or the like while looking at the display unit composed of a liquid crystal display while the light emitting / receiving unit is separated from the light transmitting window 1e (S2). Then, when the address input in the wireless address setting device is completed, the data of the setting content is transmitted by the optical wireless signal in a state where the light emitting / receiving section of the wireless address setting device is again brought close to the light transmitting window 1e of the terminal for heat ray sensor 1. To start setting (S3). On the side of the hot-wire sensor terminal 1, the data is received by the optical wireless signal transmitting / receiving section 7 and the arithmetic processing section 3 receives the data.
The arithmetic processing unit 3 stores the address data of the first to third stages in the address storage unit 5 in accordance with the above data. Here, the arithmetic processing unit 3 checks the contents of the first-stage address data (S4). If the first-stage address data is a pattern control address or is not set, the operation processing unit 3 proceeds to step S4.
The contents of the address data in the second stage are checked (S5). If the address data in the second stage is an address for individual control or an address for group control, the optical wireless signal transmitting / receiving section 7 sets the address in the wireless address setting device. Data indicating an error is transmitted (S6), and a setting error is displayed on the display unit of the wireless address setting device (S7). Also,
If the second-stage address data is a pattern control address or no setting, the arithmetic processing unit 3 checks the contents of the third-stage address data (S8), and the third-stage address data is the pattern control address or If the address is a group control address, data indicating a setting error is transmitted from the optical wireless signal transmitting / receiving unit 7 to the wireless address setting device (S9), and a setting error is displayed on the display unit of the wireless address setting device. (S7). If the third-stage address data is an individual control address or no setting, the address data is set correctly,
The arithmetic processing unit 3 stores the content of the set address data in the address storage unit 5 and transmits data indicating the completion of the setting from the optical wireless signal transmitting / receiving unit 7 to the wireless address setting device, and transmits the data to the wireless address setting device. Is displayed on the display section (S10). on the other hand,
When the first-stage address data is an individual control address or a group control address, the contents of the second-stage address data are checked (S11), and the second-stage address data is a pattern control address or a group control address. In some cases, data indicating a setting error is transmitted from the optical wireless signal transmitting and receiving unit 7 to the wireless address setting device, and a setting error is displayed on the display unit of the wireless address setting device (S7). If the address data in the second stage is an individual control address or no setting, it means that the address data has been set correctly, and
Stores the contents of the set address data in the address storage unit 5
And the data indicating the completion of the setting is transmitted from the optical wireless signal transmitting / receiving section 7 to the wireless address setting device, and the display of the setting completion is displayed on the display portion of the wireless address setting device (S10).

As described above, when the address is stored in the address storage unit 5 of the terminal 1 for a heat ray sensor, the address data of the first to third stages are sequentially transmitted using a wireless address setting device in the same manner as in the prior art. An address (first-stage address) used when sending monitoring data when a human body detection signal is set, and an address (two-stage address) used when monitoring data is inserted when a predetermined operation holding time has elapsed. (Addresses of the eyes) are stored in order, so that there is an advantage that a user accustomed to the address setting method in the conventional configuration can easily set the addresses.

Next, an actual operation example of the present embodiment, for example, when there is no person in the detection area, the illumination load L is dimmed and turned on at a low dimming level, and when a person enters the detection area, the illumination load L is turned on. A description will be given of a case where the load L is dimmed and lit at a high dimming level and the lighting load L is dimmed and lit again at the low dimming level after the operation holding time has elapsed after the person has left the detection area. When such an operation is performed, in the hot-wire sensor terminal 1, as shown in FIG. 4, a pattern control address of "P-1" is set in the first row and "P-
The pattern control address of "2" is set, and the third stage has the hot-wire sensor on / off switch Sb of the operation terminal 31.
Is set for the individual control. Also, in the dimming control terminal device 33 for controlling the lighting load L,
Same pattern control address "P-1", "P-2"
Is set. Further, using a terminal device for setting the control contents of the pattern control (the configuration of this terminal device is well known in the related art and the description is omitted), each pattern control address "P-1", "P- The control content of "2" is registered in the correspondence table of the transmission control device 30. For example, "P-
In the pattern control address of "1", the lighting load L is 30%.
The control contents to be lit at the dimming level of
The lighting load L is 90% for the pattern control address “2”.
The control contents to be turned on at the dimming level are associated with each other. In addition, in order to blink the lighting load L, with respect to the individual control address commonly set to the blinking switch Sa of the operation terminal 31 and the control terminal 37 with a built-in relay.

In addition, the function of the hot-wire sensor terminal 1 is set in response to the hot-wire sensor on / off switch Sb of the operation terminal 31 and the individual control address commonly set in the third row of the hot-wire sensor terminal 1. The control content to be turned on / off is associated.

After the above control contents are registered in the correspondence table of the transmission control device 30, the present system operates as follows.

As shown in FIG. 9, at time t = t0, a person enters the detection area and is detected by the hot-wire sensor subunit 41.
When the human body detection signal is input to the slave unit connection unit 2 of the terminal 1 for a heat ray sensor, the arithmetic processing unit 3 monitors the corresponding monitoring data (“P- stored in the first stage of the address storage unit 5”).
2) is transmitted to the transmission control device 30 and the transmission control device 30 that has received the monitoring data refers to the correspondence table and is associated with the pattern control address of “P-2”. When the control data is transmitted to the dimming control terminal 33 in accordance with the control content, the dimming control terminal 33 sets the dimming level to 90% with respect to the lighting load L.
And the lighting load L is lit and lit. Here, before time t = t0, the dimming control terminal 3
3 is 30% dimming level according to the control contents of "P-1"
Is given to the lighting load L to dimming the lighting load L. Further, the arithmetic processing unit 3 starts counting the operation holding time T from the time when the human body detection signal is input, and retriggers the count of the operation holding time T when the human body detection signal is input again during the counting ( Time t =
t1). When the counting of the operation holding time T is completed, the arithmetic processing unit 3 transmits the corresponding monitoring data (the “P-1” pattern control address stored in the second stage of the address storage unit 5) to the transmission control device. 30, the transmission control device 30 that has received the monitoring data refers to the correspondence table and sends it to the dimming control terminal 33 in accordance with the control content associated with the pattern control address of “P-1”. When the control data is transmitted, the dimming control terminal 33
Gives a dimming output with a dimming level of 30% to the lighting load L, and dims the lighting load L at a dimming level of 30%.

On the other hand, when the hot-wire sensor on / off switch Sb of the operation terminal device 31 is turned on (time t = t3),
Operation data corresponding to the operation terminal 31 is transmitted to the transmission control device 30, and the transmission control device 30 refers to the correspondence table to turn off the function of the hot-wire sensor terminal 1 and transmit control data to the hot-wire sensor terminal. When the signal is transmitted to the terminal 1, the heat ray sensor terminal 1 does not perform processing for returning monitoring data to the transmission control device 30 even when a human body detection signal is input (time t = t4). And the heat ray sensor input /
When the off switch Sb is turned off (time t = t
5), operation data corresponding thereto is transmitted from the operation terminal device 31 to the transmission control device 30, and the transmission control device 30 refers to the correspondence table to turn on the function of the hot-wire sensor terminal device 1 and transmit the control data to the hot-wire sensor. Is transmitted to the communication terminal 1, the heat ray sensor terminal 1 performs processing for returning monitoring data to the transmission control device 30 in accordance with the input of the human body detection signal, and when the human body detection signal is input, P-
By returning the pattern control address of "2" to the transmission control device 30, the lighting load L is fully lit (time t = t
6). Here, when the blinking switch Sa of the operation terminal 31 is operated, the operation data corresponding to the operation is transmitted from the operation terminal 31 to the transmission control device 30.
Transmits the control data to the control terminal 37 with built-in relay with reference to the correspondence table, and the control terminal 3 with built-in relay.
7, the power supply from the AC power supply AC is turned off by turning off the built-in relay, and the lighting load L is turned off (time t = t
7). Further, when the blinking switch Sa is operated in a state where the lighting load L is turned off, the operation data corresponding to the operation is transmitted from the operation terminal device 31 to the transmission control device 30, and the transmission control device 30 displays the correspondence table. The control data is transmitted to the built-in relay type control terminal 37 with reference to it, and the built-in relay type control terminal 37 turns on the built-in relay, thereby turning on the power supply from the AC power supply AC and turning on the lighting load L fully. (Time t = t8).

Next, another operation example of this embodiment, for example, a case where the lighting load L is dimmed and lit at a predetermined dimming level when a person is detected in the detection area will be described. When performing such an operation, the terminal device 1 for a heat ray sensor

An individual control address corresponding to the hot-wire sensor on / off switch Sb is set. The same pattern control address "P-2" is also set in the dimming control terminal 33 that controls the lighting load L. Further, the control content of the pattern control address “P-2” is registered in the correspondence table of the transmission control device 30 using a terminal device for setting the control content of the pattern control. For example, the control content for lighting the illumination load L at a dimming level of 90% is associated with the pattern control address “P-2”. In addition, in order to blink the lighting load L, the control terminal 37 of the built-in relay type control terminal 37 is controlled by the flashing switch Sa of the operation terminal 31 and the individual control address commonly set in the control terminal 37 with built-in relay. The control contents for blinking (lighting / extinguishing) the lighting load L by turning on / off the built-in relay are associated with each other, and the hot wire sensor on / off switch Sb of the operation terminal device 31 and the third stage of the hot wire sensor terminal device 1 The point of associating the control content for turning on / off the function of the hot-wire sensor terminal 1 with the individual control address commonly set in the above is common to the previous operation example.

After the above control contents are registered in the correspondence table of the transmission control device 30, the present system operates as follows.

As shown in FIG. 10, at time t = t0, a person enters the detection area and is detected by the hot-wire sensor slave unit 41, and a human body detection signal is sent to the slave unit connection part 2 of the hot-wire sensor terminal 1. When input, the arithmetic processing unit 3 returns the corresponding monitoring data (the “P-2” pattern control address stored in the first stage of the address storage unit 5) to the transmission control device 30, and Transmission control device 30 that has received the data
Refers to the correspondence table and transmits control data to the dimming control terminal 33 according to the control content associated with the pattern control address of “P-2”. The dimming output for setting the dimming level to 90% with respect to the lighting load L is output to dimming the lighting load L. Here, the state of the lighting load L before time t = t0 may be anything. After time t = t0, the monitoring data is returned from the heat ray sensor terminal 1 to the transmission control device 30 every time the human body detection signal is input, unless the state of the lighting load L is changed by other factors. The pattern control of "P-2", that is, the dimming lighting state at the dimming level of 90% is continued.

On the other hand, when the hot-wire sensor on / off switch Sb of the operation terminal device 31 is turned on (time t = t1),
Operation data corresponding to the operation terminal 31 is transmitted to the transmission control device 30, and the transmission control device 30 refers to the correspondence table to turn off the function of the hot-wire sensor terminal 1 and transmit control data to the hot-wire sensor terminal. When the signal is transmitted to the terminal 1, the terminal 1 for the heat ray sensor does not perform the processing for returning the monitoring data to the transmission control device 30 even if the human body detection signal is input. Then, the hot wire sensor on / off switch Sb
Is turned off (time t = t2), the operation terminal 31
When the transmission control device 30 transmits the control data for turning on the function of the hot-wire sensor terminal 1 to the hot-wire sensor terminal 1 by referring to the correspondence table, The heat ray sensor terminal 1 performs a process for returning monitoring data to the transmission control device 30 in response to the input of the human body detection signal. Here, when the blinking switch Sa of the operation terminal 31 is operated, the operation data corresponding to the switch is transmitted from the operation terminal 31 to the transmission control device 30, and the transmission control device 30 relays the data by referring to the correspondence table. The control data is transmitted to the built-in control terminal 37, and the built-in relay terminal 37 turns off the built-in relay to turn off the power supply from the AC power supply AC to turn off the lighting load L (time t = t3). ). Further, the switch S for blinking while the lighting load L is turned off.
When a is operated, the operation terminal 31 transmits the corresponding operation data to the transmission control device 30, and the transmission control device 30 transmits the control data to the built-in relay type control terminal 37 with reference to the correspondence table. The control terminal 37 with a built-in relay turns on the built-in relay to change the AC power supply AC.
And the lighting load L is fully lit (time t = t4).

Although the description is omitted, as shown in FIG. 5, the group control address "G-10" is set in the first row, and the hot-wire sensor of the operation terminal 31 is turned on / off in the second row. The individual control address corresponding to the control switch Sb, and collectively turn on a plurality of lighting loads L associated with the group control address "G-10" when a person is detected in the detection area. And the operation of turning off the plurality of lighting loads L collectively after the operation holding time has elapsed after the person has left the detection area, or as shown in FIG. No data is set, a pattern control address “P-2” is set in the second row, and the operation terminal 3 is set in the third row.
An individual control address corresponding to the first hot-wire sensor on / off switch Sb is set, and is associated with the pattern control address "P-1" after a lapse of operation holding time after a person is detected in the detection area. Of course, it is also possible to perform an operation of dimming and lighting the lighting load L at a predetermined dimming level. Also, as described in the conventional example, a system configuration in which an illuminance sensor is connected to the heat ray sensor terminal 1 can be employed.

By configuring the system using the hot-wire sensor terminal 1 configured as described above, desired control can be performed with a simple configuration similar to that of the conventional individual control system configuration, for example, in the detection area. When there is no person, the lighting load L is dimmed and lit at a low dimming level, and when a person enters the detection area, the lighting load L is dimmed and lit at a high dimming level and the person is no longer in the detection area. After the elapse of the operation holding time after that, it is possible to perform control such that the lighting load L is dimmed and lit again at the low dimming level.
