Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a lighting control system that centrally and remotely controls a large number of lighting loads from a main operation panel through data transmission, and in particular, relates to a lighting control system that centrally and remotely controls a large number of lighting loads from a main operation panel. The present invention relates to a lighting control system that aims to reduce the number of switches.

[Prior Art] Conventionally, in this type of system, a main operation panel, a monitoring terminal device that monitors the status of operation switches, and a control terminal device having one or more lighting load control channels are connected via a transmission line. A lighting control system is known in which a main operation panel centrally controls a lighting load connected to a control terminal by connecting the terminals and transmitting data between the main operation panel and each terminal.

In such a lighting control system, individual switches and indicators corresponding to each channel are attached to the operation section of the main operation panel, so that the usage status of the lighting can be monitored and controlled from the main operation panel. I have to.

In this way, individual switches are provided for each control channel, so in a large system with a large number of control channels, the number of individual switches increases, and the size of the system is physically restricted. This has the disadvantage of increasing the cost of the system.

[Problems to be Solved by the Invention] In view of the problems of the conventional type described above, an object of the present invention is to improve the convenience and manageability of a lighting control system in which a supervisory control switch is attached to the main operation panel. The objective is to further reduce costs by reducing the size of individual switch panels.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides means for assigning desired control channels to each lighting control switch attached to the main operation panel.

[Function] According to the above configuration, each switch for lighting control attached to the main operation panel can be used as an individual switch associated with one control channel, or as a so-called switch associated with multiple control channels. It can also be used as a pattern switch or zone switch.

The larger this type of system becomes, the more
By using individual switches, the ratio of monitoring and controlling each circuit (channel) is reduced, and there is no point in installing individual switches, which results in waste.

According to the present invention, such waste can be avoided and the necessary number of switches can be used for necessary purposes depending on the scale and purpose of the system.

Furthermore, since the number of switches is reduced, the cost becomes low and monitoring becomes easy.

[Example code] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 shows the overall configuration of a lighting control system according to an embodiment of the present invention. In the figure, 1 is a main operation panel (base unit), 3 is a two-wire transmission line, and 5 is a wall switch monitoring terminal. ,7
is a control terminal. Each control terminal 7 has one to four lighting load control channels, each control channel being connected to one or more lighting fixtures (not shown).

FIG. 2 shows the appearance of the operation panel of the main operation panel 1. As shown in FIG. In the figure, 11 indicates a lighting switch that can be assigned to any of the individual switches, pattern switches, and zone switches, and 12 indicates the control status (on or off) of the lighting load control channel assigned to the lighting switch. L.E.
D, 13 is the name plate, 14 is the card reader, 15
1 is a time schedule display section, and 16 is a time schedule setting switch.

The lighting control system of FIG. 1 includes a pattern memory,
Lighting connected to a plurality of channels assigned to these switches according to wall switch operation on each wall switch monitoring terminal 5 or operation of a pattern switch or zone switch provided on the operation panel of the main operation panel 1 In contrast to the conventional system that can control the loads all at once and also controls the lighting load of the channel corresponding to each individual switch according to the operation of the individual switches provided on the operation panel, the main operation panel 1 is By providing a switch type table for assigning whether each (lighting) switch on the operation panel is used as an individual, pattern, or zone switch, the distinction between the individual, pattern, and zone switches is eliminated.

FIG. 3 is a diagram of a switch type table.

In this table, there are 8
A bit-by-bit allocation data area is allocated.

In each assignment data, the most significant bit (MSB) b indicates the presence or absence of a group designation; if it is "1", a group designation is present, that is, the light switch is assigned as a pattern or zone switch. Also, if it is "0", there is no group designation, that is, the light switch is assigned as an individual switch. ), or an address as an individual switch (b, = "0'). Here, a group switch is a switch that corresponds to any wall switch and controls the same lighting load group as that wall switch. A zone switch is a switch that controls the lighting load assigned to the waste-free section within the control range of a wall switch.As a group switch address, the same address as the wall switch corresponding to that group switch is used. In this case, 5 of bits b6 to b2
The bits indicate the address of the monitoring terminal to which the corresponding wall switch is installed, and the two bits b6 to b2 indicate the channel (circuit) number to which this wall switch is connected. Further, as the address of the zone switch, an appropriate address that does not overlap with the loads connected to each monitoring or control terminal device is assigned.

In the pattern memory, lighting load groups that are collectively controlled by the switches are assigned in correspondence with these addresses, that is, group assignments are made.

In addition, in the switch type table, as the address of an individual switch, the address of the control terminal to which the lighting load to be controlled by the individual switch is connected is set in 5 bits b6 to b2, and the control channel number is set in bits b6 to b2. b1-b.

It is written to 2 bits of .

Such switch type assignment can be performed, for example, by writing the switch type table itself as shown in FIG. 3 into FROM or EPROM and replacing it. In addition, the switch type table can be stored in RAM.
The allocation (card allocation) may be performed by setting the area, marking it on a mark sheet as shown in FIG. 4, and reading this with a card reader such as OMR.

Furthermore, the layout (keyboard layout) may be performed by inputting data from the keyboard of the main operation panel 1. This keyboard layout can be performed, for example, by the procedure shown in FIG.

In the normal mode, that is, the lighting control mode, the main operation panel 1 monitors the status of each lighting switch 11 and also monitors the signals sent from each monitoring terminal 5 to the transmission line 3. When it is detected that one of the light switches 11 has been operated, the switch type table is referred to and the type (individual, pattern, zone) and address to which the light switch is assigned is read. If this type is an individual switch, the upper 5 bits of the address b6
A control signal for inverting the control state of the lighting load of the channel indicated by the lower two bits blNbo of the switch address is sent to the address control terminal device indicated by ~b. As a result, the lighting/extinguishing of the lighting load corresponding to this individual switch is reversed. When the operated light switch is assigned to a group or zone switch, the pattern memory is further referred to and addresses ba to b0 are assigned.
Transmits data to turn on or turn off one or more lighting loads assigned to the controller, so that control terminals to which these lighting loads are connected receive control signals to turn on or turn off the lights. , controls the lighting load connected to itself, such as turning on or off, according to the content of the control signal.

Even when the wall switches connected to the monitoring terminals are operated and monitoring data from these monitoring terminals is received, the main operation panel 1 performs the following operations in the same way as when the light switches are assigned to pattern switches. Referring to the pattern memory, a control signal for turning on or off is sent to the control terminal device to which all the lighting loads assigned to the wall switch are connected. When each control terminal device receives a control signal addressed to itself, it turns on or off the lighting load connected to itself according to the control content.

After sending these control signals, the main operation panel 1 confirms that the processing has been performed normally based on return signals from each control terminal or monitoring data from a monitoring terminal that monitors the lighting status of each lighting load. The LED 12 corresponding to the light switch is turned on or off based on the confirmation result.

In this system, by operating the light switches on the main operation panel 1, it is possible to turn on and off a desired lighting load or group of lighting loads, and by monitoring the corresponding LED of each light switch. , the entire lighting load can be monitored.

Therefore, manageability and convenience are high. In addition, the number of switches is small and the cost is low. Regarding the number of switches, for example, 80 individual switches and 2 pattern/zone switches.
We were able to achieve the same functionality as the conventional system with 0 light switches using 40 light switches.

The invention can be implemented with appropriate modifications based on the knowledge of those skilled in the art.

For example, the data transmission method between the main operation panel and the terminal device is
A so-called cyclic transmission method may also be used, in which each terminal device is accessed sequentially from the main operation panel and the data sent back from the terminal device is received as monitoring data. It may be a random transmission method in which the transmission is performed, or it may be an M-machine controlled random transmission method in which the main operation panel specifies the transmission timing and the terminal device that has generated the transmission request performs the transmission at this timing. In addition, the data transmission signal between the main operation panel and the terminal device is
Both may be sent as voltage signals as has been conventionally done, as disclosed in Japanese Patent Application Laid-Open No. 193493/1983.
As shown in the following, the signal from the main operation panel may be sent in voltage mode, and the signal from the terminal device may be sent in current signal.

[Scope of Application of the Invention] Note that the present invention is limited to the embodiments described above. [Effects of the Invention] As explained above, according to the present invention, it is possible to reduce the number of switches and configure the system at low cost. can.
