Abstract

PURPOSE:To prevent a user from making a mistake by an indicator lamp being lighted after loads are turned off by performing OFF control for all of the loads, and then outputting an OFF control signal to the indicator lamp of the control switch. CONSTITUTION:The main control portion 22 of a host machine reads from a pattern storage portion 23 a load alloted to the control switch of a pattern monitoring terminal so as to determine whether OFF control is performed for all of loads. When OFF control is performed for all of the loads, a transfer control portion 21 performs OFF control for all of the loads and actuates a timer circuit 24 to perform control, by that, after a fixed time is measured, an OFF control signal is output to the indicator lamp of the control switch. Therefore a user, when seeing the indicator lamp being lighted regardless of the loads being turned off, does not mistake either of the loads corresponding to the pattern monitoring terminal for being lighted.

Description

Detailed Description of the Invention

[0001]

[Industrial field of application] A master unit and a plurality of control terminals and pattern monitoring terminals are connected through a pair of transmission lines,
The present invention relates to a lighting monitoring control system in which a signal from a master unit is sent in a voltage mode and a signal from a terminal unit is sent in a current mode to monitor and control a load connected to a control terminal unit.

[0002]

2. Description of the Related Art A master unit is connected to a plurality of control terminals and pattern monitoring terminals via a pair of transmission lines, and signals from the master unit are transmitted in a voltage mode. Signals are sent in current mode to monitor the load connected to the control terminal.
A lighting monitoring control system that performs control is known. In such a lighting monitoring control system, the pattern monitoring terminal has an operation switch for selecting a pattern and an indicator light for displaying whether or not the pattern is selected. The machine has a storage means for storing a load pattern assigned to the pattern monitoring terminal.

As for the indicator light of the pattern monitoring terminal device, the load pattern stored in the master unit is selected by the operation switch or the load state is changed to the pattern by operating the individual monitoring terminal device. The light is turned on when the pattern becomes full, and turned off when all the patterns are broken.

[0004]

However, even if the load is turned off when a pattern is assigned and operated to turn off all the loads stored in the master unit as the pattern, the load of the terminal unit is turned off. The indicator light remains on.

However, in this case, the user sometimes sees that the indicator lamp is lit and makes a mistake when any of the loads corresponding to the pattern monitoring terminal is lit.

The present invention has been made in view of the above points, and an object thereof is to prevent a user from seeing an indicator lamp and making a mistake when one of the loads is lit. To provide a surveillance system.

[0007]

A lighting monitoring control system according to the present invention connects a master unit and a plurality of control terminals and pattern monitoring terminals through a pair of transmission lines, The signal from the terminal is sent in the voltage mode and the signal from the terminal is sent in the current mode to monitor and control the load connected to the control terminal, and the pattern monitoring terminal is The master unit has an indicator light for indicating ON / OFF of each operation switch for selecting a pattern, and the master unit is a load pattern assigned to each operation switch of the pattern monitoring terminal.
In a lighting monitoring control system having a storage unit for storing an operation switch, an operation detection unit for detecting an operation of the operation switch, and a display corresponding to the operation switch when the operation detection unit detects that the operation switch is operated. A means for outputting a lighting control signal for lighting the lamp, and a pattern detecting means for detecting whether or not all loads corresponding to the operation switches stored in the storage means are controlled to be turned off, When it is determined that all the patterns are controlled to be extinguished by the pattern detecting means, all the loads corresponding to the operation switches are extinguished, and then an extinction control signal is sent to the indicator lamp of the operation switches. And output control means.

[0008]

[Operation] When the operation switch of the pattern monitoring terminal is operated, the indicator light corresponding to the operation switch is turned on, and then it is judged whether all the load patterns corresponding to the operation switch are controlled to be turned off. In this case, after outputting the turn-off signal to all the loads assigned to the pattern monitoring terminal, the turn-off control signal is output after a certain period of time.

EXAMPLE Next, an example of the present invention constructed as described above will be explained. FIG. 1 is a block diagram showing a schematic configuration of a lighting monitoring system, FIG. 2 is a block diagram showing a configuration of a master unit, and FIG. 3 is a diagram showing one format of a voltage mode signal sent from the master unit. 4 is a flowchart for explaining the operation of the master unit. In FIG. 1, 11
Is the parent machine. A pattern monitoring terminal device 13, a control terminal device 14 and the like are connected from the master device 11 via a two-wire transmission line 12. The master device 11 is provided with a memory for storing the allocation to the pattern monitoring terminal device 13.

The pattern monitoring terminal unit 13 has operation switches 131 arranged in three stages in the center thereof, and a lighting indicator 132 and an extinguishing indicator 133 are provided so as to sandwich the operation switch 131. The operation switch 131 is a switch for designating a load pattern corresponding to this switch. The control terminal 14 can be connected to, for example, four circuit lighting loads.

Next, the configuration of the base unit 11 will be described with reference to FIG. In FIG. 2, the transmission line 12 is connected to the main control unit 22 via the transmission control unit 21. The main control unit 22 is mainly composed of, for example, a microcomputer. The main control unit 22 has a pattern monitoring terminal 13
The pattern storage unit 23 for storing which circuit of the control terminal device 14 is assigned to each operation switch is also connected to the timer circuit 24.

The pattern storage unit 2 is supplied to the main control unit 22 by an operation signal from the operation panel of the master unit 11 itself or from another operation device (not shown) connected to the transmission line 12.
