Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control operation of a terminal device in a system for remotely centrally controlling a lighting device for 1 hour.

In recent years, in order to save energy and eliminate unnecessary lighting, lighting has been turned on manually. Patterned flj that groups control and lighting circuits according to the time of day! There are many devices that perform intensive blinking and dimming control, such as I control and daylight usage control. In this type of device, as shown in the configuration diagram of the lighting control system in Figure 1, a main operation panel (1) is provided in the center to perform various settings such as blinking and dimming of the lighting, execution of signal transmission, etc. Connect multiple terminal devices [31+41...] with unique addresses via the signal transmission line (2). Lighting device (6al (6b) (6c) (6d) connected to Ox ) (OR) (04)
) is blinking/dimming controlled. Further, the terminal device (5) transmits remote information 1, for example, the status of a remote control switch (8) +91, to the main operation panel, and the main operation panel judges reception and controls the corresponding lighting device. α[1] is also a remote control switch and is connected to the input terminal (XS) of the terminal (3). )
connected to. In this way, the terminal device has input and output terminals and can be used for controlling lighting, monitoring switches, monitoring other things, etc. As shown in the second port transmission signal diagram, the transmission signals between the main operation panel i11 and the terminal are address signals (TA) and control signals (TO) for blinking and dimming of multiple lighting devices connected to one terminal. ) is added and transmitted to the terminal, and a return signal (fTB) for transmitting information from the terminal to the main operation panel is then placed on the transmission line. In this type of equipment, where these series of transmission signals are communicated by multiplex transmission such as a polling method or a symmetric time division method, each terminal device has a unique address and has a unique input/output terminal as described above. Since the device is used to send and receive transmission signals, it is necessary to use a terminal device with a different address even if it is used only for control output or for monitoring input. In particular, if several terminal devices used only for output are to be controlled in the same way, the same number of addresses will be exclusively used. For this reason, it is difficult to use limited addresses effectively.

In view of the above points, the present invention aims to provide a terminal device with a changeover switch that changes its operation depending on the purpose, and to set the terminal device to be input-only, output-only, or input/output-only depending on the switch settings. .

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

(15b) ON) executes the initial setting of the terminal device for input/output only (2υ).The processing unit then performs the following steps:
It executes a processing routine determined based on the above initial settings.

For example, when the mode setting switch (IS) is set for output only, it receives and determines the blinking/dimming control signal (TO) from the main operation panel (1), performs lighting control processing, and outputs the output terminal (0+ ) (Owl (OJ (O4)) generates a control output corresponding to each circuit, and uses this output to control the blinking and dimming of the υ lighting device. Also, in this terminal operation, the input terminal (Is) (Is ) (Eng+.HIn) data is not converted to a return signal (TB).If mode setting switch 09 is set to input only, input terminal
) to (T++) are input, judged as 1, and synchronized with the same address.

A return signal (TB) is carried on the transmission line. However, lighting control processing based on the contents of the control signal ('I''O) is not performed.Furthermore, in the nine-person/output-only terminal setting, both the output control and input control operations described above are executed.

As described above, by changing the mode setting switch, you can set the terminal to input-only, output-only, or input/output-only. It becomes possible to use a terminal device address repeatedly, such as using an output-only terminal device and an input/output-only terminal device with the same address.

Note that in the above embodiment, the processing unit (IQ input terminal (I
Although a remote control switch is connected to 8) to (In), a sensor transmission terminal may be used to input the output of a sensor such as a daylight sensor and transmit a signal to the main operation panel.

As described above, the present invention has a main operation panel and a plurality of terminals, and uses multiplex transmission to blink and flash the lighting equipment connected to the terminals.
In devices that control dimming.

The terminal device is equipped with an operation mode setting switch, and there is an output-only terminal device that controls lighting flashing and dimming by switching this switch, an input-only terminal device that sends terminal side data to the main operation panel, and an input-only terminal device that can perform both input and output operations as described above. Since the terminal is set as an input/output-only terminal that performs
