Benefits of technology

The present invention is about a switch and a system of switches that can be configured in a flexible way without adding too much complexity or cost. The technical effect of this invention is that it provides a more flexible and cost-effective solution for switch configuration.

Problems solved by technology

Today, the known switch systems provide that, once the switches have been installed on the wall and electrically connected to the respective electrical utilities to be controlled, it is no longer possible to modify the control configuration, or to control different utilities that are not originally provided unless there is an intervention on electrical wiring, masonry works and power distribution in the electric system.
This system is rather flexible, but it implies several drawbacks due to the fact that:
the entire electrical system must have been designed according to home automation logics (therefore this system is not applicable to old systems already installed);
it is necessary to use different “smart” components which entail a significant increase in costs during the construction phase of the electric system.

Embodiment Construction

[0048]The system 100 consists of switches 1 connected to each other by a bus 6 (preferably an industrial RS485 serial network). This network allows the devices to communicate even at great distances.

[0049]Each device has a serial interface 5 (RS485), three keys and some microswitches 11 for programming, some LEDs 22, and three input channels 16 or output 13 of the input device 15 or output device 12. Three of the LEDs 22 display the status of the three input channels 16 or output channels 13. Each device must be powered by a power supply 21 for the control unit 24 and for the serial connection.

[0050]Each switch 1 must be programmed with its own identification address (node) in order to be able to communicate with the other switches 1 in the serial network.

[0051]In a same network there can be switches with the same “node” (alias), whose operation and behavior are defined according to the relative programming. Such “alias” switches advantageously allow the keys of a second switch 1 co...

Abstract

A programmable logic switch (1) for controlling electrical utilities (3), has multiple control devices (2) of the electrical utilities (3), a serial interface (5) for connecting the switch (1) to an electrical bus (6) to which other switches (1) can be connected. The serial interface (5) is configured for receiving input signals (7) from other switches (1) and transmitting output signals (8) towards other switches (1). The switch (1) comprises an output device (12) having output channels (13) connectable to the electrical utilities (3) and separate with respect to the serial interface (5), and being configured for generating control signals (14) of the electrical utilities (3) as a function of any combination of signals chosen among control signals (4), programming signals (10) and input signals (7), so to control the electrical utilities (3) as a function of a command operated by a user and programming data.

Description

TECHNICAL FIELD[0001]The present invention falls within the field of switches which are preferably installed in buildings (house, offices, boxes, . . . ) for the control of electrical utilities (lamps, motors, fans, air-conditioners, solenoid valves) and to receive signals, if any, from external devices such as photocells, timers, detectors.[0002]These switches are preferably (but not exclusively) installed in the common wall boxes and are connected to each other by electric cables.BACKGROUND ART[0003]Today, the known switch systems provide that, once the switches have been installed on the wall and electrically connected to the respective electrical utilities to be controlled, it is no longer possible to modify the control configuration, or to control different utilities that are not originally provided unless there is an intervention on electrical wiring, masonry works and power distribution in the electric system.[0004]Other known solutions are based on the use of so-called “home...
