Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a lighting control system that controls lighting loads connected to a plurality of terminals.

(Prior art) Conventionally, a terminal device to which lighting loads such as lighting equipment are connected is connected to a main operation panel through a transmission line, and each lighting load can be controlled such as blinking or dimming by operating the main operation panel. A lighting control system is known. In such a lighting control system, in order to improve the convenience of control operations, for example, a control signal is transmitted to the main operation panel in response to the operation of a wall switch installed on the wall of the house. The main control panel is configured to control the corresponding lighting load, allowing the operator to control the lighting of desired lighting equipment not only from the main control panel but also by using nearby wall switches. there were.

(Problem to be Solved by the Invention) However, in such conventional lighting control systems, even when using a wall switch to control lighting, the operator does not have to go to the wall switch. However, it is very inconvenient to operate, especially when there is no wall switch nearby. Furthermore, if there is no place to mount a wall switch due to the structure of the house or other reasons, there is also the inconvenience that local control of lighting equipment using a wall switch is not possible.

Therefore, as a solution to this inconvenience, a method of controlling by using a familiar telephone may be considered. However, there is nothing that takes into account dirt on the pump and the decline in light output over time due to lamp life, which have started to become a problem with the rise of intelligent amenities in recent years, and therefore nothing has been done to address these issues. The current situation was that there was no such thing.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a lighting control system that allows users to easily know when to control lighting and when to clean the lighting load or when to replace lamps by using a nearby telephone. The aim is to improve convenience and manageability in the field.

[Structure of the Invention] (Means for Solving the Problems) A lighting control system according to the present invention transmits control and information included in signals sent from a main operation panel and a telephone to the main operation panel. The intaffny unit is connected to one or more lighting loads, and controls the lighting loads based on control signals sent from the main operation panel via the transmission line, and sends a signal indicating the lighting state of the lighting load via the transmission line. The lighting control terminal that replies to the main operation panel compares the returned signal with the preset limit lighting state data of the lighting load, and when the data exceeds the limit lighting state data, a sound is heard. and audio signal generating means for generating a signal and sending it to the telephone to cause the telephone to generate a marginal tone. Each telephone is connected via a private branch exchange to an interface unit that allows control of the lighting from the telephone, either connected to the interface unit or directly to the main control panel.

(Function) In the above-described configuration, when information indicating, for example, the number of the lighting load to be controlled and the details of the control is input by dialing or pressing the telephone, each piece of information is sent to the interface unit via the private branch exchange. The interface unit sends this information to the main operation panel. Based on the control information sent from the interface unit in this way, the main operation panel creates a transmission signal that includes an address signal indicating the address of the controlled lighting load or terminal device, and a control signal indicating the details of the control of the lighting load. This transmission signal is sent out via a transmission line.

Then, the limit lighting state of the lighting load is displayed in correspondence with the terminal device corresponding to the address signal included in this transmission signal. In other words, the limit lighting state is displayed when the terminal transmits a signal indicating the current lighting state to the main operation panel via a transmission line based on the input from the lighting load that corresponds to the lighting state of the lighting load connected to it. The signal is sent back to the telephone set by the signal generating means when the signal is set by storing the above signal in advance using RO)4, etc., and the telephone set generates voice.

(Example) Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a schematic configuration of a lighting control system according to an embodiment of the present invention.
The main operation panel 1 is equipped with a lighting terminal 5 connected to the transmission line 3 and an operation section 4 provided on the main operation panel 1. One or more terminals 5 are connected to the transmission line 3. pcs are connected. Here, a plurality of lighting devices 5 are connected, for example, it is divided into three zones, ten or more terminal devices 5 are assigned to each zone, and each terminal device 5 is connected to one or more lighting devices 9. . The lighting fixtures 9 in each zone were installed at the same time, and the degree of decrease in light output due to dirt or longevity is the same in the same zone. Further, the lighting fixture 9 sends input to the terminal device 5 according to the lighting state. These inputs are respectively input to a plurality of terminal devices 5, but since all the lighting loads connected to the control terminal device 5 for each zone were replaced at the same time, the lighting conditions are almost the same. The inputs depending on the lighting state are also almost the same. Therefore, the input to the terminal device 5 may be a sample of the input from one terminal device 5 per zone, but it is also possible to average the inputs from all the terminal devices 5 and use that as the input. It is something. The input obtained in this way is
The comparator 11 compares the input value with the limit lighting data stored in advance in the ROM built into the main operation panel 1 or the storage means 10 that stores data manually using keys, and determines that the input value is the same as the limit lighting data. A signal is generated in the signal processing section 12 at the point when the value becomes larger or larger.

The above lighting limit data is, for example, when using a lamp rated at 1000LX to obtain an appropriate illuminance of 700LX, taking into account dirt on the lamp and inputting 80% of the rated value to the lighting load. Such values are stored as limit lighting data. Over a long period of time, it becomes impossible to maintain 700LX in the initial lighting state due to a decrease in luminous flux over the course of the lamp's life and a decrease in luminous flux due to dirt on the lamp.

At this time, use your phone to increase the dimming level to 700LX.
However, after making this adjustment many times, there comes a time when it is not possible to maintain 700LX unless the rating exceeds 80X. At this time, a signal is given from the comparison section 11 to the signal processing section 12, and a signal is given from the signal processing section 12 to the PBX interface 7. In response to this signal, a signal is given from the signal processing device 19 to the limit sound generating section 21, and the limit sound generating section 21 generates a limit sound to the telephone to notify that it is time to clean the lamp. That is, in this embodiment, the main operation panel 1 and the PBX interface 7 constitute an audio signal generating means. The above dimming limit data is arbitrary, and the rated 10oz
In this case, after the dimming limit is displayed from the above-mentioned telephone, even if you clean the lamp and try to obtain 700Lx again, when the dimming limit is displayed, This indicates that it is time to replace the lamp. Further, the main operation panel 1 may have a built-in PBX interface, and the signal generating means may be constituted by one CPU.

In the lighting control system shown in FIG. 1, the terminal device 5
In addition to being able to perform blinking, dimming, and other lighting control on/off and other operations of the lighting equipment 9 connected to the , it is also possible to similarly control the lighting of the desired lighting equipment 9 by operating the telephone 14 .

First, the case where control is performed by operating the main operation panel 1 will be explained. By operating a switch or the like on the main operation panel 1, information for specifying the controlled object, such as the number of the controlled lighting equipment or the number of the terminal device 5 to which these are connected, and the control details for this controlled object are transmitted. The specified information is input. Based on this information, the main control panel 1 generates an address signal consisting of the number of the controlled lighting device, the number of the terminal device, etc., and the control for specifying the control content of the controlled lighting device, etc. A transmission signal including the signal is generated and sent to the transmission line 3. This transmission signal is read by each terminal device 5, and it is determined whether the content of the address signal included in the transmission signal matches the address number assigned to each terminal device.

Then, the terminal device that has matched the two reads the transmission signal, assuming that the transmission signal has been transmitted to its own terminal device, and controls the dimming of the lighting fixture 9 corresponding to the address signal, such as PWH control or phase control. Control such as output adjustment is performed according to the content of the control signal.
Each time the button [6] of the telephone is pressed once (if it is a dial type, the dial [6] is turned once), a dimming signal for one level is sent to the terminal 5, and the light output is increased by one level. In other words, the above dimming step is increased by, for example, phase control, and each time [6] is pressed, the duty is increased.
Increase the dimming intensity by changing the ratio.

Next, a case where appropriate illuminance setting control is performed from the telephone 14 will be described. By dialing or pressing a key switch on the telephone 14, information indicating the numbers of the controlled lighting fixtures and their terminals and control information indicating the control details of the controlled lighting fixtures are input from the telephone 14. This information is, for example, DTHF (Dual T.

neHulti-Frequency) signal is sent to the PBX interface 12 via the private branch exchange 13. The PBχ interface 12 detects the signal thus received, converts it into a transmission signal similar to that generated when a switch is operated, for example, and transmits it to the main operation panel 1 via the transmission line 3. When the transmission signal is transmitted to the main operation panel 1 in this way, the main operation panel 1 transmits signals including the address signal and the control tXl signal to each terminal device in the same way as before, and controls the lighting load. , Figure 2 shows the PBX
As shown in the figure showing the detailed configuration of the interface 7, the PBX interface 7 includes a line control section 15, a signal detection section 17, a signal processing device 19, a limit sound generation section 21,
It is equipped with a transmission interface 23 and the like.

In the PBX interface 7 shown in FIG. 2, a line control unit 15 controls the telephone line connected to the private branch exchange 13, such as forming a loop, and operates a line switch for receiving signals sent from each private branch exchange R13. Close 25. DTH from telephone 14 via private branch exchange R13
When control information etc. are sent by F signals or audio signals, the signal detection unit 17 converts each of these signals into predetermined two
Convert to base digital signal. The signal processing device 19 is composed of, for example, a microprocessor, and the signal detection unit 1
The binary digital signal input from 7 is decoded and determined to generate a transmission signal, and this transmission signal is transmitted to the main operation panel 1 via the transmission interface 23.

The transmission signal input to the main operation panel is first input to the signal processing unit 12, converted to a dimming signal, and transmitted to the addressed terminal device 5, which is a dimmable terminal device composed of a transistor, a cyrisk, etc. 5, the lighting load 9 is dimmed and controlled. The lighting state at this time, that is, the dimming control fX
The l signal is sent back to the main operation panel 1, and the comparison section 1 of the main operation panel 1
1, a limit signal is sent to the signal processing section 12 when the signal is compared with the limit lighting data stored in the storage section 10 and is equal to or larger than the limit lighting data. When the signal processing section 12 receives the limit signal as described above, it outputs a limit display signal from the limit sound generating section 21. The limit signal is sent back to the telephone set 14 and the receiver 14
generate sound from the speaker.

FIG. 3 shows a telephone set 1 in the lighting control system described above.
4 exemplifies the key switch operation procedure when inputting lighting load control information and the like.

That is, when controlling a lighting fixture or the like by operating the telephone 8i14, for example, as shown in FIG. 3(a), first dial the extension number of the telephone line to which the PBX interface 12 is connected, and then turn dial the number indicating the terminal number, etc., and finally enter the number indicating the control details. As a number indicating this control content, for example, in the case of on/off control, "0" corresponds to off operation,
“1” can correspond to an on operation. In addition, by setting these control numbers to various values, you can control various aspects such as the strength of the output.Also, as shown in Figure 3(b), after first inputting the extension number, turn on the # key. It is also possible to configure the device number and control number to be input after that. Alternatively, as shown in FIG. 3(C), by first turning on the # key and then inputting a specific number, such as "9", instead of the extension number, call 8! i1
4 can be connected to the interface 12. In this way, after connecting the telephone 8114 to the interface 12, the appliance number, control number, etc. are entered manually as before. The control number is input later. In this way, the control numbers are changed one after another [(
6 is uP) (9 is down) As you input +6], the lighting load gradually becomes brighter, and the value on the illuminometer increases accordingly. Therefore, if the illuminance meter is, for example, 7
When it reaches 00Lx, the user stops inputting 6 and hangs up the receiver, and the switch 25 of the line control section 15 is turned off, thus completing the illuminance setting. However, as you repeat this kind of illuminance setting over and over again in a room over a long period of time, even if the input to the lighting equipment is 80% of the rated value, it becomes 7001. This results in a state where x cannot be obtained. At this time, the limit sound generating section 2
The signal from 1 causes the phone to make a sound indicating that it is time to clean or replace the lamp. In addition, although the above description has been made on the assumption that necessary control information, etc. is inputted manually from the telephone R14 using the keys, it is also possible to configure the system so that the control information for the lighting load, etc., can be input by voice from the telephone 14, for example. . In this case, for example, private branch exchange fi13 or PBX interface 12
A voice analysis device is provided in the system and can analyze input voice signals to generate predetermined control signals and the like. Further, in the above-described system, it is also possible to use a wall switch in combination so that each lighting fixture can be controlled from this wall switch as well. Further, in the present invention, it is of course possible to directly correspond to each telephone and the lighting fixture of the zone in which the telephone is placed, so that the fixture numbers can be omitted in FIG.

[Effects of the Invention] As described above, according to the present invention, it is possible to control the illuminance setting of each lighting load from a telephone, so it is not possible to install it in a place far from the main operation panel or on a wall switch. Each lighting fixture can be easily controlled from any location without having to install wall switches or the like at various locations. Moreover, when the control input value of the lighting equipment is compared with the lighting limit data stored in the storage section of the main operation panel, and the input value is the same as or larger than the lighting limit data, a signal is sent. Since the generation means sends a signal to the telephone to display the lighting limit, it is easy to know when it is time to replace or clean the lamp. Furthermore, since the position of the telephone is generally a proper illuminance measurement position in many cases, there is no need to move the telephone during illuminance measurement work, and the efficiency of the measurement work can be improved. Therefore, the convenience and manageability of illuminance measurement are improved. Additionally, existing in-house telephone systems and lighting control systems can be used, making system construction economical. Furthermore, since the telephone speaker can be used as a marginal sound generator, the system can be provided at a low cost.
