Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a multi-device control system that controls a plurality of controlled devices, particularly an air conditioner, using one remote controller.

[Prior Art] Conventionally, a system for controlling a plurality of controlled devices at once using a single remote controller has generally been configured as shown in FIG. In the figure, 1 is a remote controller, and an operation circuit 11
and a driving command signal transmission circuit 12. Reference numerals 2, 3, and 4 designate a plurality of device controllers, each of which includes a control circuit 21, 31, and 41 and an operation command signal receiving circuit 22, 32, and 42;
0 and 40 are controlled devices, for example, air conditioners, which are controlled by the device controllers 2, 3, and 4, respectively, and 5 is a signal line.

In the control system configured as described above, from the remote controller 1 to the operation circuit 11
The transmission circuit 12 transmits a single operation command obtained by
A serial operation command signal is converted into a serial operation command signal and sent to a plurality of device controllers 2, 3, and 4 via a signal line 5 to simultaneously control a plurality of controlled devices 20, 30, and 40. Therefore, when starting the operation, each controlled device 20, 30, 40 is started at the same time. Therefore, the power supply capacity of the entire system had to be able to withstand the starting current caused by simultaneous operation of the plurality of controlled devices 20, 30, and 40.

In particular, when operating multiple controlled devices with large starting currents, such as air conditioners, at the same time,
In particular, a large power supply capacity was required.

[Summary of the invention]

This invention has been made in view of the above points, and it provides different delay times to operation command signals to each device controller, and allows multiple controlled devices to be controlled at different times by a single operation command. The purpose of this invention is to provide a multiple device control system that avoids simultaneous activation and does not require a large capacity power source by starting the devices at the same time.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing an embodiment of the present invention, in which the same parts as in FIG. multipole switch, 24,3
Reference numerals 4 and 44 designate delay circuits having delay times corresponding to the opening/closing contact positions of these multi-pole switches.

Next, its operation will be explained. Now, for example, as shown in the figure, so that the opening/closing contact positions of the multipole switches 23, 33, 43 of each device controller 2, 3, 4 are different.
Switch 23 has all contacts open, switch 33 has the first
It is assumed that the switch 43 is set so that the contact is closed. These multi-pole switches 23, 33,
Delay circuit 24, 3 depending on the closing contact position of 43
Different delay times are set in 4 and 44, respectively. Therefore, the driving command signals transmitted from the transmitting circuit 12 of the remote controller 1 are simultaneously received by the receiving circuits 22, 32, and 42, respectively, but are delayed by the delay circuits 24, 34, and 44, and the driving commands are Each takes effect at different times,
The signal is applied to the control circuits 21, 31, and 41. Therefore, the controlled devices 20, 30, and 40 are sequentially started at different times, preventing simultaneous starting, and a large starting current is not generated, making it possible to reduce the power supply capacity.

In the above explanation, an example is shown in which a delay circuit that delays the received signal is used, but other circuits may be used as long as they are valid after a predetermined period of time after receiving the driving command. It may be incorporated into a circuit, for example, by a microcomputer. Of course, the multi-pole switch is not limited to the one shown in the drawings, but may be of other types.

〔Effect of the invention〕

Since this invention is configured as described above,
A plurality of controlled devices can be activated at different times with a single simultaneous command without changing the operation command signal in any way, and simultaneous activation is prevented and the power supply capacity can be reduced.
