Abstract

PURPOSE:To permit to cope even with forgetting to switch off lights through a remote control device, by making it possible to control lighting devices through a main operation panel set, whether either of local control/central control has control priority. CONSTITUTION:At the close of work, the output condition of a flip-flop 15 is set to a local control priority side, and when a centralized control is made to simultaneously switch off lighting devices 5a to 5d by a main operation panel 1, a reset signal to a remote control switch 19 is transmitted by the main operation panel 1 to a remote control device 25 via a transmission line 1. When an operational inputting terminal unit 7 in the remote control device 25 receives this reset signal, it allows a reset output terminal 20 to output a reset pulse to a toggle circuit 17. Upon receiving this reset pulse, the toggle circuit 17 is reset for restoring its output to its initial condition. The initial condition of the toggle circuit 17 is predetermined to have central control priority setting so that posterior to resetting the remote control switch 19, the lighting devices, 5a to 5d and 6a to 6d can be switched off by the main operation panel 1. This makes it possible to cope even with forgetting to switch off lights by the remote control device.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a method for connecting a large number of lighting devices via a plurality of terminals.
This relates to a lighting control system that centrally controls from the main operation panel and remotely controls each lighting device.

[Conventional technology]

FIG. T is a block diagram of a conventional lighting control system shown as a conventional example in, for example, Japanese Utility Model Application Publication No. 60-80696, and FIG. 8 is a block diagram showing a remote control device of this system. In the figure, (l) is the main operation panel that is the main operation device, (2) is the transmission line, and (3) and (4) are the control terminals e (5a) to (5d)? (6a) ~ (6d
) is the lighting device, {F} is the operation input terminal, (8) is the local control/central control priority selection switch, 《9》 is the remote control switch, and the trout is the control unit of the operation input terminal (7) ,U, is its input terminal, and @ is its remote control device.

As shown in Figure 7, the main operation panel (b) is located at the central K.
Main operation panel {1
} The lighting devices (5a) ~ (5d) F (6a) ~ connected to the terminals (3) and (4) according to commands from
(6d) is blinking and dimming controlled. In addition, the operation input terminal <<7>> has two switches connected to it (
8) and (9) are sent to the main operation panel (b), and the remote control device (to) is connected to two switches (8).
1 and (9), a predetermined lighting device is controlled via the main operation panel <<1>>.

As mentioned above, the lighting control system incorporates multiple lighting control functions, but they can be broadly divided into control request input from the remote control device (to) by opening and closing the two switches (8) and (9). There are two functions: local control and central control such as manual or time-based control from the central main operation panel (1).

In order to allow these two different types of control functions to coexist, a local control/central control priority selection switch (8) is provided here as a switch to set whether to give priority to local control or central control. There is. In other words, when the local control/central control priority selection switch (8) is turned on, local control is given priority and the main control panel (
Regardless of the content of the control request from b), the lighting device is controlled by the open/closed state of the remote control switch (9). Conversely, when the local control/central control priority selection switch (8) is turned off, the central control takes priority regardless of the open/closed state of the remote control switch (9). The lighting device is controlled by the content of the control request on the main operation panel (b1).

[Problem to be solved by the invention]

Conventional lighting control systems are configured as described above, so a local control/central control priority selection switch (
8) is on and local control is given priority, control cannot be performed from the main operation panel (b) which is the main operation device. In other words, if we consider the case where this system is applied to Pill as an example, at the end of the workday, even if you try to turn off all the lighting devices from the K main operation panel (b1), the local control/central control priority selection switch (8) K If control is given priority, the lighting devices cannot be turned off all at once.

In order to turn off the lighting system, K must go from the main operation panel (b) installation location to the remote control device (to) installation location and switch the local control/central control priority selection switch (8) to central control priority. .

This invention was made in order to solve the above-mentioned problems, and even in the case of forgetting to turn off the light using the remote control device, it is possible to solve the problem by simply operating the main control device. The aim is to obtain a control system.

[Means to solve the problem]

The lighting control system according to the invention K has a main operating device and a remote control device each equipped with the following means.

(IL) Means possessed by the main operating device (a1) Control means for sending control signals to the control terminal (a2) Means for transmitting operation information of the main operating device to the remote control device (a3) Operations from the remote control device Means for receiving and storing information (a4) Means for switching the device that controls the control terminal (b) Means possessed by the remote control device (b1) Control means for sending the control terminal K control signal (b2) Main operating device To. Means for transmitting operation information of the remote control device (b3) Means for receiving, storing and displaying operation information from the main operation device.

[Effect]

The lighting control system according to the present invention includes a main operating device that includes:
To provide means (a4) for switching the device that controls the control terminal to which the lighting device is connected, change local control to central control, and switch from the remote control device to the main operating device K.
This also includes cases where it is possible to switch to another by giving priority. Also, if this switching is not known to each other, there is a risk that the next operation of the main operating device and remote control device will not be executed correctly.
Means (a2), (a3), (t+2), (b3) for communicating operation information with each other and storing it so that the latest status can be seen.
). In addition, the means (b1) for controlling the control terminal from the remote control device is conventionally controlled via a similar means (a1) of the main operating device even when the remote control device directly sends control signals. Even when sending a signal,
Either case is fine.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

First, a case in which the main operating device switches local control to central control will be explained.

FIG. 1 is a block diagram showing a remote control device (c) of a lighting control system according to an embodiment of the present invention. In Figure K, (2) is the signal transmission line to the main operation panel f1+ which is the main operation device, (7) is the operation input terminal, I and a3 are its input terminals, (8), (9) (8) is a push switch whose contact is normally open and closes only when operated, (8) is a local control/central control priority selection≠≠ middle 1 switch,
(9) is a 3☆ control one-nana switch. α$
, al is a D-type flip-flop with a reset terminal, a
The force is a clip-flop α field, a toggle circuit consisting of a wire,
(IS is an indicator that displays the output status of the toggle circuit fin, α
Reference numeral 9 denotes a scan signal output terminal for receiving switch inputs, and (self) a reset output terminal for outputting a reset pulse to the toggle circuit (lη) in response to reception of a reset signal from the main operation panel 0).

In the above configuration, push switches (8), (
9) is operated, a pulse is input to the toggle circuit (Iη).The toggle circuit αη is a general-purpose D with a reset terminal.
It consists of type 7 lip-flops α and αe, and the previous output state is reversed every time a pulse is input. The output of the toggle circuit αη is input to the input terminals (b1) and aa, and is transmitted through the operation input terminal (7) to indicate the state of the switch on the main operation panel (
! ) will be sent to. The output of the toggle circuit .alpha..eta. is further input to a display circuit a, which is configured to enable the remote control device (c) to grasp the state of the switch. When acquiring the switch status with the operation input terminal (7), output the switch status acquisition pulse from the scan output terminal (b!J), and input the status of each switch from the input terminals I and α. .

A reset pulse is output from the reset output terminal (support) in response to reception of a remote control switch reset signal from the main operation panel (b) of the operation input terminal (f).

Next, a case will be described in which this embodiment is applied to a lighting control system for a building.

Under normal operating conditions, this remote control device performs the same function as a conventional remote control device. That is,
When performing local control, operate the local control/central control priority selection 1 or 4 switch (8) while checking the display (II) to select local control priority for the output state of the 7 flip-flops. The output state of the 7-lip 7-log αe is set to the desired output state by operating the remote control switch (9).The state of the toggle circuit a?l, that is, the open/close state of the switch It is displayed on the display panel, and input to the operation input terminal (7) from the input terminals an and α, and then to the main operation panel (b).
A predetermined illuminator is controlled by the control signal from the main operation panel ill. Similarly, if central control priority is selected, the main operation panel 11) (k), manual operation (b), will only be controlled according to the time.

Flip 7 lop a at the end of the day! The civil power status of 9 is set to K with local control priority side, and if you want to centrally control these to turn them off all at once from the main operation panel (b1), you can use the remote control device @K from the main operation panel (b). In response, a remote control switch reset signal is transmitted via the transmission line (2).When the operation input terminal (7) of the remote control device (c) receives this signal, it is sent from the reset output terminal member to the toggle circuit αη. A state reset pulse is output to the toggle circuit aη. When the toggle circuit aη receives this pulse, it is reset and the output returns to the initial state. Since the initial state of the toggle circuit αη is set to give priority to central control, remote control After resetting the switch, it is possible to turn off the main operation panel (1) lighting device.

As described above, in this embodiment, the main operation panel (b) is provided with means for obtaining center priority by transmitting a reset signal.
In this way, it is possible to obtain a remote control device for a lighting control system that can be handled by operating the main operation panel (b) even if the user forgets to turn off the light using the remote control switch K.

Although the above embodiment shows an example in which two D-type flip-flops are used as toggle circuits, other circuits with similar functions may also be used. Although a switch that closes is used, a switch that is normally closed and opens only when operated may be used.

Next, another embodiment of the present invention will be described based on FIG.

Here, we will explain the case where the main operating device can freely switch between local control and central control.

FIG. 2 shows a configuration diagram showing another embodiment of the lighting control system according to the present invention, and the same (equivalent) components in the conventional example shown in FIG. T are denoted by the same (equivalent) symbols.

(C) is the input switch for operating the main operation panel (b), (O) is the numeric keypad for inputting numbers, (O)
is the main control panel《! This is a display section that displays the operation details and input switches. In Fig. 2, the main difference from the conventional one is the local control/central control priority selection switch (8
) is absent.

Figure 3 shows the display contents accompanying the operation of the operation content display section (to) when the priority switching between local control and central control on the main operation panel (b) in the present invention K is set to center priority. It is a chart figure showing the change of.

FIG. 4 shows the display contents accompanying the operation of the operation contents display section (self) when the priority switching between local control/central control on the main operation panel (b) in the present invention K is set to local priority. It is a chart diagram showing changes.

In this embodiment, the local control/central control priority selection switch (8) is eliminated from the remote control device (to).
This function has been moved to the main operation panel (b).

For the main operation panel (b), either central priority or local priority can be selected when setting the system or at any time.

First, the operation when the local control/central control priority is set to the central priority button will be explained using FIG. 3.

When attempting to operate the lighting device (5a) connected to the control terminal (3) (hereinafter referred to as circuit 1), Fig. 3a

), the display contents on the display section (to) become as shown in FIG. 3b.

Next, in order to operate the circuit 1, when the user operates the switch (21a) under the display "CIRCUIT" and the numeric keypad (TO), the display contents on the display section (TO) become as shown in FIG. 3C.

Next, if you want to turn off this circuit 1, operate the switch (z1b) below the 'Off' display, and the display (
The display contents of the control terminal (3) are displayed as shown in Figure 3 (d), and are transmitted from the main operation panel (b) to the control terminal (3
) transmits a control command for the lighting device (5a). This information is also sent to the remote control device.

Next, the operation when the priority of local control/central control is local priority will be explained using FIG. 4.

When attempting to operate the lighting device (5 &) of circuit 1, in Fig. 4 aK, when the switch (21a) under the display ``operation'' is operated, the display content on the display section (to) changes to the 4th section.
It will look like Figure b.

Next, in order to operate the circuit 1, when the switch (21a) under the display "Circuit" and the numeric keypad (To) are operated, the display contents on the display section (To) become as shown in FIG. 4C.

Next, if you want to forcibly turn off this circuit 1, operate the switch (21a) below the display "y", and the display contents on the display section (c) will become as shown in FIG. 4d.

Next, turn on the switch that says “Off” (z1b
), the display contents on the display section (self) will change as shown in Figure 4e, and the contents will be changed from the main operation panel (b) to the control terminal (3) via the transmission line (2). A control command for the lighting device (5a) is transmitted. At the same time, this information is also transmitted to the remote control device.

Next, we will explain the overall control of the main operation panel (!) and remote control device (c).

FIG. 5 is a flowchart showing the flow of control on the main operation panel <<1>>. The main operation panel 《1》 usually checks whether there is a transmission from the operation input terminal (7) (aTygp 1), and if there is a transmission, it stores the operation information and uses it as necessary. If there is, a control signal is sent to the control terminal and the lighting is controlled. Also, when "operation" is selected (8TKP2), the above-mentioned figures 3 and 4
Perform control according to the operation shown in the figure. When "setting" is selected (sTzxs 4), the initial state and initial values of the system, such as assignment of the control terminals (31, (4)) and the remote control device (to), are set.

Also, selection of local control/central control can be made at this selection time. Other parts are omitted because they are not directly related to the present invention.

, if transmitted, this information is stored and the latest information is displayed on the display aυ. In addition, when the remote control switch (9) is operated (sTxpll), information on ON or OFF is sent to the main operation panel (b) for the currently stored state K, and the display is displayed. change.

In this embodiment, since there is no local control/central control priority selection switch (8), the remote control device (self)
However, if the main operation panel (b) is configured to automatically give local priority after a certain period of time or after a certain operation is completed, the input from remote control device 4 will be no longer possible. As usual, there is almost no hindrance.

In this way, it is possible to obtain a lighting control system that can respond to the forgetting to turn off the lighting by the remote control device (self) by operating the main operation panel (b).

〔Effect of the invention〕

As explained above, according to the present invention, the lighting device can be controlled from the main operating device regardless of whether the control priority is local control or central control. It is also possible to obtain a lighting control system that can respond to operations from the main operating device.
