[0018]

[Object of the Invention] Therefore, the present invention provides one control means,
The present invention provides a control system for an illuminated signboard in which wiring between a plurality of driving means is made as simple as possible.

[0019]

[Means for Solving the Problems] A control system for an illuminated signboard according to the present invention includes a plurality of loads such as lighting devices, a plurality of drive means for driving the loads, and one control means for controlling the drive means. a power supply means for supplying power to the drive means and the control means; a power line connecting the drive means, the control means and the power supply means in parallel; and a power line for supplying drive signals to the plurality of drive means via the power line. It consists of a drive signal transmitting means provided in the control means for transmitting, and a drive signal receiving means provided in the drive means for receiving the drive signal from the control means via a power line.

[0020]

[Function] With the illuminated signboard having the above configuration, there is only an electric light line connected in parallel between one control means and a plurality of drive means, and the drive signal is transmitted through this electric light line. Since the information is transmitted from the control means to the drive means, wiring can be significantly reduced.

[0021]

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 3.

FIG. 1 is a block diagram of a control system 10 showing one embodiment of the present invention.

[0023] Symbol X is a commercial power source. This commercial power supply is single-phase two-wire 100V, or single-phase three-wire 100V.
It is 0V and may be a DC power supply.

Reference numeral A denotes a control device consisting of a microcomputer. The control device A includes a control circuit E, a power supply circuit F, and a signal generation circuit G, as shown in FIG. Power terminal 1
A commercial power supply X is connected to 2.

The power supply circuit F sends the commercial power taken in from the power supply terminal 12 to the control circuit E to operate the control device A. Further, the signal generation circuit C superimposes a control signal on the electric light line Y connected to the power supply terminal 12 under the control of the control circuit E. As for this multiplication method, the electric light line Y is 50H.
z or 60Hz AC power supply, so the control signal is 1
It is preferable to perform multiplication using an FM modulation method of approximately MHz.

[0026] Symbol C is a load. There are n loads C.

Reference numeral B indicates a drive device for driving the load C. There are n driving devices B, and the load C and 1
It is provided on a 1-to-1 basis. As shown in FIG. 3, the drive device B includes a control circuit H, a power supply circuit I, a signal reception circuit J, and a load switch circuit K. A commercial power supply X is connected to the power supply terminal 14, and a load C is connected to the load terminal 16.

The power supply circuit I sends the commercial power taken in from the power supply terminal 14 to the control circuit H to operate the drive device B. Further, the signal receiving circuit J reads a control signal from the control device A superimposed on the power line Y, and sends the received data to the control circuit H. If the received control signal is a command to the drive device B, the control circuit H operates according to the command. The load switch circuit K controls the load C by supplying or cutting off power to the load terminal 16 under the control of the control circuit H.

The commercial power supply X, the control device A, and the n driving devices B are connected in parallel by a power line Y. Thereby, the power necessary to operate the control device A, the drive device B, and the load C can be supplied from the commercial power source X.

The operating state of the system 10 having the above configuration will be explained below.

It is assumed that commercial power is supplied to the power line Y and each device is operating.

For example, if the control device A sends a command to the drive device B1 to turn on the light and to the drive device B2 to turn off the light, the drive device B1 supplies power to its load terminal 16 and turns on the load C1. Further, the drive device B2 cuts off the power at the load terminal 16 and turns off the load C2. At that time, the other drive device B3
to Bn continue in their previous states, and the loads C3 to Cn connected to their load terminals 16 continue in their previous states.

[0033] Furthermore, the control device A controls all the drive devices B1.
When a lighting command is sent to Bn from B1 to Bn, B1 to Bn supplies power to the load terminals 16, and lights up loads C1 to Cn.

In the system 10 having the above configuration, only the electric light line Y is connected between the control device A and the drive device B, and the wiring can be greatly reduced and simplified compared to the conventional one. Reduces work and wire usage. In addition, since wiring is simplified, incorrect wiring is eliminated.

[0035]

[Effects of the Invention] As described above, in the control system for the illuminated signboard of the present invention, only the electric light wire is wired between the control means and the drive means, so that the number of wires can be greatly reduced and the system can be easily and easily installed. Therefore, wiring work and wire usage can be reduced, and incorrect wiring can be eliminated.
