The present invention relates to a remote control device for lighting equipment configured to control the driving of lighting equipment connected to a terminal device by sending and receiving information.

As shown in FIG. 2, the conventional remote control device for lighting equipment connects a parent device 3 and a terminal device 4 with two multiplex transmission lines 2 separate from the power line 1, and connects the multiplex transmission line 2 with the terminal device 4. By transmitting and receiving a series of signals including an address signal, a control signal, and a return signal consisting of positive and negative pulse signals between the master unit 3 and the terminal device 4, the lighting equipment 5 connected to each terminal device 4 is controlled.

When there is a short circuit or disconnection in the multiplex transmission line 2 for remote control, the lighting fixture 5 will go out, and the remote control will become impossible, making it impossible to turn on the light, which poses a safety problem. It was hot.

る。 To solve this problem, the emergency lighting device disclosed in Japanese Utility Model Application Publication No. 52-157278 supplies power to the operation relay through the connection lead, and the operation relay is disabled when the connection lead is short-circuited or opened. The structure is configured to turn on the illumination lamp by utilizing the excitation, and to ensure safety by turning on the illumination lamp in the event of a short circuit or disconnection between the connecting leads.

In a configuration that uses the fact that the operation relay becomes de-energized when the connection leads are short-circuited or disconnected to ensure safety by lighting the lighting lamp, the operation relay requires a considerable amount of energy to keep the operation relay energized at all times. It is necessary to pass a current of

全性の確保は困難である。 If this type of short-circuit or disconnection detection configuration using constant excitation is applied to remote control of lighting equipment connected to multiple terminal devices through multiplex transmission, it would be necessary to install one for each terminal device. Excitation current must be passed through all of the relays connected to the terminal, and as the number of terminal devices increases, the output current capacity of the parent device must be increased. In other words, it is not possible to constantly excite the relays installed in multiple terminal devices with the current output from the main device, which has a small output current capacity that is enough to send signals.
With the constant excitation method, it is difficult to ensure safety in devices that perform multiplex transmission.

用上非常に安全である。 According to the configuration of the present invention, the latching relay is used to switch the lighting equipment on and off, and the capacitor is charged when the multiplex transmission line is normal.
When a multiplex transmission line is short-circuited or disconnected, the capacitor charge is discharged through the on-winding of the latching relay, thereby forcibly switching the relay contact of the latching relay to the on-side.
When a short circuit or disconnection occurs in the multiplex transmission line for remote control, the lighting equipment can be reliably turned on and used, regardless of whether it was previously on or off. Above is very safe.

It is only necessary to charge the capacitor, and the output current capacity of the parent device only needs to be small regardless of how many terminal devices there are. In other words, even when transmitting and receiving signals between multiple terminal devices using a master device with a small output current capacity, it is possible to ensure safety by ensuring that the lighting equipment lights up in the event of a short circuit or disconnection of the multiplex transmission line. It's easy.

きる。 Moreover, the configuration is such that when the multiplex transmission line is de-energized, the pre-charged capacitor is discharged through the on winding of the latching relay to switch the latching relay to the on side. It is possible to ensure safety by lighting the lighting equipment without requiring a special line for lighting the lighting equipment in the event of a short circuit or disconnection.

In order to turn on the transistor 23, the transistor 23 is turned off, and the on winding 21a and the off winding 21b of the latching relay 21 appear at the two output terminals a and b of the logic circuit 17 in response to the signal from the multiplex transmission line 2. Alternately energized by the output. That is, when outputs are applied to both output terminals a and b, transistors 24 and 25 are turned on, and on-winding 21a of latching relay 21 is excited. When an output is given only to output terminal b, the transistor 25 is turned off.
Transistor 24 turns on, which turns on transistor 26, and energizes off winding 21b of latching relay 21. On winding 21 like this

る。 Now, suppose that the relay contact 14' is in the OFF state, and at this time, if the power supply to the terminal device is stopped due to a short circuit or disconnection of the multiplex transmission line 2, no current will flow to the photodiode 8 of the input section 6'. , phototransistor 1 of output section 9'
0 is turned off, the discharge current of the capacitor 22 flows to the base of the transistor 23 for a short time after a short circuit or disconnection occurs, and the transistor 23 is turned on. Therefore, during this time, the discharge current of the capacitor 22 flows through the on winding 21a of the latching relay 21 and is excited, thereby reversing the relay contact 14' from the off state before the short circuit or disconnection occurs to the on state.

器具Lを点灯状態に導くことができる。 Therefore, in cases where it is dangerous that the lighting equipment L to be controlled is permanently fixed in the off state due to a short circuit or disconnection of the multiplex transmission line 2, this device It is possible to always lead the lighting fixture L to the safe side, that is, to the lighting state. Note that, not only in the case of a short circuit or disconnection of the multiplex transmission line 2, but also in the case where the rectifier capacitor 19 along with the rectifier bridge 7 breaks down, the photocoupler can detect this and guide the lighting fixture L to the lighting state. .

確認する必要がない。 Further, although an inspection is performed before shipping, stopping the power supply at the end of the inspection is the same as disconnection, and as a result, the relay contact 14' of the latching relay 21 is turned on in the same manner as described above. In other words, the relay contact 14' remains on continuously from shipping to installation. Therefore, even during temporary power transmission during construction, simply connecting the lighting equipment to the power source will ensure that it will turn on, and there is no need to check the status of the relay contacts each time.
