BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring control system, and more particularly to a remote monitoring control system having a heat ray sensor terminal 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, as a remote monitoring control system, one having a structure shown in FIG.
0-108279). In the figure, a maximum of four loads L can be individually controlled by one control terminal 32. That is, a 2-bit load number is set in each control terminal 32 in addition to the control address individually given to each control terminal 32, and which load L is controlled by designating the load number. You can choose. Similar to the control terminal 32, the operation terminal 31 is set with an operation address and a load number, and a maximum of four operation switches S0 can be connected.

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

The transmission control device 30 is connected to the signal line Ls by
The transmission signal Vs having the format shown in FIG. 17A is transmitted. That is, a synchronization signal SY indicating the start of signal transmission, mode data MD indicating the mode of the transmission signal Vs, address data (including load number) AD for individually calling the operation terminal 31 and the control terminal 32, and a load L Control data CD for control, checksum data CS for detecting a transmission error, and a signal return period W which is a time slot for receiving a return signal from the operation terminal 31 or the control terminal 32.
It is a bipolar (± 24 V) time-division multiplexed signal composed of T, and data is transmitted by pulse width modulation (FIG. 17 (b)). In each operation terminal device 31 and each control terminal device 32, when the address data AD transmitted by the transmission signal Vs received through the signal line Ls matches the preset operation address or control address, the transmission signal The control data CD is fetched from Vs, and the monitoring data is returned as a current mode signal (a signal sent by short-circuiting the signal line Ls via an appropriate low impedance) during the signal return period WT of the transmission signal Vs.

From the transmission control device 30 to the desired operation terminal device 3
When transmitting data to 1 or the control terminal device 32, a transmission signal Vs in which the mode data MD is set to the control mode and the operation address or the control address of the operation terminal device 31 or the control terminal device 32 is set to the address data AD. When the transmission signal Vs is transmitted and is transmitted to the signal line Ls, the operation terminal device 31 or the control terminal device 3 that matches the address data AD.
2 receives the control data CD and returns the monitoring data during the signal returning period WT. In the transmission control device 30, the control data CD is the desired operation terminal device 3 according to the relationship between the transmitted control data CD and the monitoring data received during the signal return period WT.
1 or the control terminal 32 confirms that the data has been transmitted.
The control terminal device 32 outputs a load control signal for controlling the load L according to the received control data CD, and the operation terminal device 31 outputs a monitoring signal for performing an operation confirmation display of the load L according to the received control data CD. To do.

On the other hand, the transmission control device 30 always sends out the transmission signal Vs in which the mode data MD is in the dummy mode at regular time intervals, and the operation terminal device 31 causes the transmission control device 3 to operate.
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 dummy mode transmission signal Vs. At this time, the operation terminal device 31 sets an interrupt flag to prepare for the subsequent information exchange with the transmission control device 30. Transmission control device 30
Then, when the interrupt signal is received, the mode data MD is set to the interrupt polling mode and the transmission signal is transmitted while sequentially increasing the upper half bits of the address data AD (upper 4 bits when the address data AD is 8 bits). Then
In the operation terminal device 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 device 31, During the signal return period WT, the lower half bits of the operation address are transferred to the transmission control device 30.
Return to. In this way, the transmission control device 30 collectively searches for 16 operation terminals 31 that have generated an interrupt signal, so that the operation terminals 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 sent to the signal line Ls. In response to this transmission signal, the operation terminal device 31 returns the information to be transmitted during the signal return period WT. Finally, the transmission control device 30 sends a signal for instructing an interrupt reset to the operation terminal device 31 that generated the interrupt signal, and clears the interrupt flag of the operation terminal device 31. As described above, the information transmission from the operation terminal device 31 to the transmission control device 30 is carried out four times by the signal transmission from the transmission control device 30 to the operation terminal device 31 (dummy mode, interrupt polling mode, monitoring mode, interrupt mode). Complete reset). When the transmission control device 30 wants to know the desired operating state of the control terminal device 32, it only has to send out 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 device 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
Is supplied with a load monitoring input, the monitoring data corresponding to the load monitoring input is returned to the transmission control device 30, and the returned monitoring data is transmitted to the operation terminal device 31. The operation terminal 31 outputs a monitoring signal in response to this transmission signal. The monitoring output is normally the lighting of an operation confirmation lamp consisting of a light emitting diode.
It is used to turn off the lights.

In the illustrated remote monitoring control system, a dimming control terminal 33 is connected to the signal line Ls, which controls the light output of a lighting load, which is a load. When the increase or decrease of the light output of the illumination load is instructed, the light output is changed over time, and when the stop of the light output is instructed by another transmission signal, the change of the light output is stopped. The dimming control terminal device 33 is associated with the dimming operation terminal device 38, and the dimming operation terminal device 38 is provided with an operation unit for instructing increase and decrease of the light output of the load L. When the operation unit is pushed, the light output of the dimming control terminal 33 is changed by the transmission signal. When the operation of the operation unit is stopped (that is, the pressing operation is stopped), the change of the optical output is stopped in the dimming control terminal device 33 by another transmission signal. The dimming operation terminal device 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 this operation unit, the previous light output is obtained when the load L is turned on next time. The load L is lit. The previous light output is stored in each dimming control terminal device 33.

By the way, in this type of remote monitoring control system, since the correspondence between addresses on the operating side and the controlling side is managed by the transmission control device 30, the transmission control device 30 deals with one operation address. By associating a plurality of control addresses with each other, it is possible to control a plurality of loads L collectively by one switch S0. Such collective control includes group control and pattern control. Group control controls a plurality of loads to the same control state, and pattern control controls a plurality of loads to a preset control state. The collective control operation terminal device 39 for performing group control or pattern control uses an operation address defined as collective control, but the other configuration is the same as other operation terminal devices. In the illustrated example, the dimming operation terminal device 3
A collective control operation terminal 39 of the same type as that of No. 8 is provided, and a plurality of loads L can be dimmed all at once by the collective control operation terminal 39.

By the way, 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 the heat ray sensor detects a person (movement of a person) in the detection area, the monitoring data for operating the load (for example, lighting the lighting load) is returned to the transmission control device 30, and detected by the heat ray sensor. By sending back the monitoring data 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 person is detected in the area, Heat ray sensor terminal 4 that enables load control according to the presence or absence of people
There is 0.

FIG. 18 shows an example of a system configuration for turning on / off the lighting load L using the heat ray sensor terminal 40. The heat ray sensor terminal 40 used here is of a type in which the heat ray sensor is built in the body of the terminal, and is embedded in the ceiling surface or the like of the detection area. Also,

It is possible, and the size of the detection area can be changed by combining the heat ray sensor terminal 40 and the heat ray sensor slave unit 41. In addition, the signal line Ls is supplied with power from a commercial power source to the lighting load L /
A relay control terminal 36 for controlling the latching type remote control relay 35 for turning off, a blinking switch Sa for turning on / off the lighting load L, and a heat ray sensor terminal 40.
An operation terminal unit 31 having a heat ray sensor on / off switch Sb for turning on / off the function of is connected. Here, 50 is a remote control transformer that creates and supplies an operating electric wire (AC 24V) for the remote control relay 35 and the relay control terminal 36 from a commercial power source. The address of the heat ray sensor terminal device 40 is associated with the address of the relay control terminal device 36 that controls the remote control relay 35 for turning on / off the lighting load L in the transmission control device 30.

The operation of the above system will be briefly described. First, a person enters the detection area and the heat ray sensor terminal 4
0 or when the heat ray sensor of the heat ray sensor slave unit 41 detects and inputs the human body detection signal, the heat ray sensor terminal device 40 transmits monitoring data (data indicating that the output is on) corresponding to the human body detection signal. When it is returned to the transmission control device 30 and the transmission control device 30 transmits the control data to the relay control terminal device 36 according to the correspondence relationship of the addresses,
The relay control terminal 36 turns on the remote control relay 35 to turn on the lighting load L. Then, when the operation holding time elapses, the heat ray sensor terminal device 40 returns corresponding monitoring data (data indicating that the output is off) to the transmission control device 30, and the transmission control device 30 causes the relay control terminal device. When the control data is transmitted to 36, the relay control terminal 36 turns off the remote control relay 35 to turn off the lighting load L. Here, the address of the blinking switch Sa of the operation terminal device 31 is also associated with the address of the relay control terminal device 36, and the lighting load L is forcibly turned on / off by operating the blinking switch Sa. be able to.

FIG. 19 shows another example of the system configuration. The heat ray sensor terminal 40 used here does not have the heat ray sensor built into the body of the terminal but has the heat ray sensor slave unit 4 described above.
1 is of a type that is connected by a dedicated signal line and is usually arranged on a distribution board. An illuminance sensor 42 for detecting ambient illuminance can be connected to the heat ray sensor terminal 40. When 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 the human body detection signal is input. Return to device 30. Here, 37 is a control terminal device with a built-in relay in which the relay control terminal device 36 and the remote control relay 35 in the previous system configuration example are integrated.

The operation of the above system will be briefly described. First, when a person enters the detection area and is detected by the heat ray sensor of the heat ray sensor slave unit 41 and the human body detection signal is input to the heat ray sensor terminal device 40, the ambient illuminance is higher than a predetermined value set in advance. When the detection signal indicating low is input from the illuminance sensor 42, the monitoring data corresponding to the human body detection signal (data indicating that the output is on) is returned to the transmission control device 30, and the ambient illuminance is preset. If the detection signal indicating that the value is higher than the predetermined value is input from the illuminance sensor 42, the monitoring data is not returned. When the transmission control device 30 that receives the monitoring data transmits the control data to the relay built-in type control terminal device 37 according to the correspondence relationship of the above addresses, the relay built-in type control terminal device 37 turns on the built-in relay and lights the lighting load L. Let Then, when the operation holding time has elapsed, the heat ray sensor terminal 40 returns the corresponding monitoring data (data indicating that the output is off) to the transmission control device 30, and the transmission control device 30

[0015]

By the way, in recent years, there has been a demand for comfort of the lighting environment and energy saving, and in a system for controlling the lighting load L using the heat ray sensor terminal 40 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 rating, and when there is no person, the rating is 3%.
By turning on the dimming level at about 0%,
There is a demand to save energy while realizing a more comfortable lighting environment than turning off the lights when there are no people.

However, the above-mentioned conventional heat ray sensor terminal 40 outputs data indicating ON / OFF of the output as monitoring data and mainly controls individual lighting load L to be turned on / off, or a plurality of units. This is for performing group control for collectively turning on / off the lighting load L, and lighting the lighting load L at a dimming level different from that when a person is detected as described above and after the operation holding time has elapsed. Was difficult. That is, the dimming control terminal device 33 for dimming the lighting load L sends the dimming signal for setting the desired dimming level according to the control data to the lighting load (inverter type capable of continuous dimming). Fluorescent lamp illuminating device) L. On the other hand, in the lighting load L composed of the above-mentioned inverter type fluorescent lamp lighting fixture, the dimming output from the dimming control terminal device 33 is turned on when the dimming output is turned on, and all lights are turned on when the dimming output is turned off. Is configured. Therefore, in the system using the conventional heat ray sensor terminal 40, as shown in FIG. 21, from the time when a person enters the detection area and the human body detection signal is output until the operation holding time elapses. The dimming output of the dimming control terminal 33 is turned on,
Since the dimming output is turned off at other times, the lighting load L is fully turned on when there is no person, and the lighting load L is dimmed and turned on when a person is detected, which is completely opposite to the desired operation. It becomes the operation of. That is, in order to realize the desired operation, as shown in FIG. 22, the dimming control terminal is operated from the time when a person enters the detection area and the human body detection signal is output until the operation holding time elapses. The dimming output of the device 33 must be turned off, and the dimming output must be turned on at other times. Therefore, the conventional heat ray sensor terminal 40 is used to perform the desired operation. Therefore, the system configuration as shown in FIG. 23 had to be used.

Here, in the transmission control device 30, the address of the heat ray sensor terminal 40 is associated with the address of the relay control terminal 36, and the address of the contact monitoring terminal 43 is the address of the dimming control terminal 33. Is associated with.

The operation of the above system will be briefly described. First, when a person enters the detection area and is detected by the heat ray sensor of the heat ray sensor slave unit 41 and a human body detection signal is input to the heat ray sensor terminal device 40, monitoring data corresponding thereto is sent to the transmission control device 30. When the transmission control device 30 which has returned and received the monitoring data transmits the control data to the relay control terminal device 36 in accordance with the correspondence relationship of the addresses, the relay control terminal device 36 turns on the main circuit of the remote control relay 35 '. At this time, as shown in FIG. 24, the remote control relay 3
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 device 43. The contact monitoring terminal 43 to which the contact signal is input transmits the corresponding monitoring data to the transmission control device 30.
When the transmission control device 30 which has received the monitoring data returns the control data to the dimming control terminal device 33 in accordance with the address correspondence, the dimming control terminal device 33 is turned on until then. Lighting load L by turning off the output
All lights up. Here, the control data transmitted from the transmission control device 30 to the dimming control terminal device 33 is pattern control data for simultaneously lighting all of the plurality of lighting loads L. Then, when the operation holding time elapses, the heat ray sensor terminal 40 transmits the monitoring data corresponding thereto to the transmission control device 3
0, and the transmission control device 30 causes the relay control terminal 3
6 transmits the control data to the relay control terminal device 36.
Turns off the main circuit of the remote control relay 35 '. 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 device 43. The contact monitoring terminal device 43 to which the contact signal is input returns the corresponding monitoring data to the transmission control device 30, and the transmission control device 30 receiving the monitoring data receives the monitoring data according to the address correspondence, and the dimming control terminal device. When the control data is transmitted to 33, the dimming control terminal 33 turns on the dimming output, which has been turned off until then, and dims the lighting load L. Here, the control data transmitted from the transmission control device 30 to the dimming control terminal device 33 is pattern control data for dimming and lighting a plurality of lighting loads L all at the same or different dimming levels.

According to the above system configuration, the illumination load L is dimmed and lit at a low dimming level when there is no person in the detection area, and when the person enters the detection area, the illumination load L is fully lit. It is possible to realize control such that the illumination load L is dimmed and turned on again at the dimming level after the operation holding time elapses after the person is no longer in the detection area.

"G" or "P" indicating the pattern control address is displayed, and the channel and load number or group number or pattern number is displayed in the vertical column adjacent to the right. In the heat ray sensor terminal device 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 the address used when transmitting the monitoring data when the human body detection signal is input. Further, a pattern control address can be set in the address of the second stage, and when the pattern control address is set, it becomes an address used when sending the monitoring data when the operation holding time has elapsed. However,
As shown in FIG. 5, only when the individual control address or the group control address is set in the first stage, the individual control address corresponding to the heat ray sensor on / off switch Sb of the operation terminal device 31 is set. It will be possible. Note that only the individual control address corresponding to the heat ray sensor on / off switch Sb of the operation terminal device 31 can be set as the third-stage address.

Next, the procedure for setting address data in the heat ray sensor terminal 1 using the wireless address setting device will be described with reference to the flow charts of FIGS. First, in the state where the light emitting / receiving unit of the wireless address setting unit is brought close to the light transmitting window 1e of the heat ray sensor terminal 1, the contents of the address storage unit 5 are confirmed by the wireless address setting unit by the optical wireless signal (S1). While the light emitting / receiving unit is separated from the translucent window 1e, a desired address is input using a ten-key or the like while looking at the display unit formed of a liquid crystal display (S2). When the address input in the wireless address setting device is completed, the light receiving / emitting unit of the wireless address setting device is again brought close to the light transmitting window 1e of the heat ray sensor terminal 1, and the data of the setting contents is transmitted by the optical wireless signal. Is transmitted to start setting (S3). On the side of the heat ray sensor terminal 1, the optical wireless signal transmission / reception unit 7 receives the above data and the arithmetic processing unit 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 according to the above data. Here, the arithmetic processing unit 3 checks the contents of the address data of the first stage (S4), and if the address data of the first stage is a pattern control address or there is no setting, it is set to 2
The content of the address data of the second stage is checked (S5), and when the address data of the second stage is the address for individual control or the address for group control, the optical wireless signal transmission / reception unit 7 sets it to the wireless address setter. Data representing an error is transmitted (S6), and the setting error is displayed on the display unit of the wireless address setting device (S7). Also,
When the address data of the second stage is the pattern control address or there is no setting, the arithmetic processing unit 3 checks the contents of the address data of the third stage (S8) and the address data of the third stage is the pattern control address or When the address is a group control address, the optical wireless signal transmission / reception unit 7 transmits data indicating a setting error to the wireless address setting unit (S9), and the display unit of the wireless address setting unit displays a setting error. (S7). If the address data in the third row is the individual control address or is not set, the address data is set correctly,
The arithmetic processing unit 3 stores the contents of the set address data in the address storage unit 5, and at the same time, transmits the data indicating the completion of the setting from the optical wireless signal transmission / reception unit 7 to the wireless address setting device, Is displayed on the display section of (S10). on the other hand,
If the first-stage address data is the individual control address or the group control address, the contents of the second-stage address data are checked (S11), and the second-stage address data is the pattern control address or the group control address. In some cases, the optical wireless signal transmission / reception unit 7 transmits data indicating a setting error to the wireless address setting device, and the setting error is displayed on the display unit of the wireless address setting device (S7). Further, when the address data of the second stage is the address for individual control or is not set, since the address data is set correctly, the arithmetic processing unit 3
Displays the contents of the set address data in the address storage unit 5
At the same time, the optical wireless signal transmission / reception unit 7 transmits data indicating the completion of setting to the wireless address setting device, and the completion of setting is displayed on the display unit of the wireless address setting device (S10).

When addresses are stored in the address storage unit 5 of the heat ray sensor terminal 1 as described above, the wireless address setting device is used in the same manner as in the conventional case to sequentially address the first to third address data. Addresses used when sending monitoring data when a human body detection signal is input (first-stage addresses) and addresses used when monitoring data is inserted when a predetermined operation holding time has elapsed (two-stage addresses) This is advantageous in that a user who is accustomed to the method of setting an address in the conventional configuration can easily set the address, since the addresses are stored in order.

Next, an actual operation example of the present embodiment, for example, when there is no person in the detection area, the lighting load L is dimmed and turned on at a low dimming level, and when a person enters the detection area, the lighting is turned on. A case will be described in which 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 elapses after a person is no longer in the detection area. When such an operation is performed, in the heat ray sensor terminal 1, as shown in FIG. 4, a pattern control address "P-1" is set in the first stage and "P-" in the second stage.
The pattern control address "2" is set, and the heat ray sensor on / off switch Sb of the operation terminal device 31 is provided in the third row.

Further, by using a terminal device for setting the control content of the pattern control (the structure of this terminal device is well known in the art, the description thereof will be omitted), the respective pattern control addresses "P-1" and "P-" are used. The control content of "2" is registered in the correspondence table of the transmission control device 30. For example, "P-
Lighting load L is 30% for the pattern control address "1".

When control data is transmitted to the dimming control terminal device 33 according to the control content, the dimming control terminal device 33 sets the dimming level to the lighting load L by 90%.
The lighting load L is dimmed and turned on. Here, before the time t = t0, the dimming control terminal device 3
3 sets the dimming level to 30% according to the control content of "P-1"
The dimming output is given to the lighting load L to dimming the lighting load L. 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 counting of the operation holding time T when the human body detection signal is input again during counting ( Time t =
t1). When the operation holding time T is counted, the arithmetic processing unit 3 sends the corresponding monitoring data (the pattern control address of "P-1" stored in the second stage of the address storage unit 5) to the transmission control device. The transmission control device 30 which has returned the monitoring data to the control unit 30 refers to the correspondence relationship table, and transmits it to the dimming control terminal device 33 in accordance with the control content associated with the pattern control address “P-1”. When the control data is transmitted, the dimming control terminal device 33
Applies a dimming output to the lighting load L to set the dimming level to 30% to light up the lighting load L at the dimming level of 30%.

On the other hand, when the heat ray sensor on / off switch Sb of the operation terminal 31 is turned on (time t = t3),
The operation data corresponding to the operation data 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 off the function of the heat ray sensor terminal device 1 to obtain the control data. When it is transmitted to 1, the heat ray sensor terminal device 1 does not perform the process for returning the monitoring data to the transmission control device 30 even if the human body detection signal is input (time t = t4). And with heat ray sensor
When the off switch Sb is turned off (time t = t
5), the operation data corresponding to the operation data 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 obtain the control data for turning on the function of the heat ray sensor terminal device 1. When the human body detection signal is input, the heat ray sensor terminal 1 performs processing for returning monitoring data to the transmission control device 30 in response to the input of the human body detection signal. P-

The individual control address corresponding to the heat ray sensor on / off switch Sb is set. The same pattern control address “P-2” is also set in the dimming control terminal device 33 that controls the lighting load L. Furthermore, the control content of the pattern control address “P-2” is registered in the correspondence table of the transmission control device 30 using the terminal device for setting the control content of the pattern control. For example, the pattern control address of "P-2" is associated with the control content for lighting the lighting load L at the dimming level of 90%. Further, in order to blink the lighting load L, the blinking switch Sa of the operation terminal device 31 and the individual control address commonly set in the relay built-in type control terminal device 37 correspond to the relay built-in type control terminal device 37. The control contents for blinking (turning on / off) the lighting load L by turning on / off the built-in relay are associated, and the third step of the heat ray sensor on / off switch Sb of the operation terminal device 31 and the heat ray sensor terminal device 1 is provided.

Then, after the 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, but 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 heat ray sensor on / off switch Sb of the operation terminal device 31 is turned on (time t = t1),
The operation data corresponding to the operation data 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 off the function of the heat ray sensor terminal device 1 to obtain the control data. When it is transmitted to 1, the terminal 1 for heat ray sensor does not perform the process for returning the monitoring data to the transmission control device 30 even if the human body detection signal is input. Then, the heat ray sensor on / off switch Sb

An individual control address corresponding to the switch Sb is set, and when a person is detected in the detection area, the plurality of lighting loads L associated with the group control address "G-10" are collectively turned on. In addition to performing the operation of turning off the plurality of lighting loads L collectively after the operation holding time elapses after the person disappears from the detection area, or as shown in FIG. Without setting the data, the pattern control address "P-2" is set in the second step, and the operation terminal 3 is set in the third step.
The individual control address corresponding to the heat ray sensor on / off switch Sb of 1 is set, and is associated with the pattern control address "P-1" after the operation holding time has elapsed after a person is detected in the detection area. Of course, it is also possible to perform the operation of turning on the lighting load L thus obtained at a predetermined dimming level.
