Definitions

  • the invention relates to an installation, in particular a busbar system, having a data line, comprising a voltage source, a group of several connected terminals and at least one control unit for controlling the terminals via the data line.
  • a busbar system having a data line, comprising a voltage source, a group of several connected terminals and at least one control unit for controlling the terminals via the data line.
  • Such an installation may be a busbar system or even a wired installation.
  • a typical busbar system for example, works with lights or other devices that have a ballast.
  • the ballast can be digitally controlled via an interface.
  • a well-known control protocol is the "Digital Addressable Lighting Interface" (DALI).
  • DALI Digital Addressable Lighting Interface
  • Each ballast belonging to a terminal can be controlled individually via a DALI address. This makes it possible, for example, to detect failures, turn devices on and off, to dim or to move via a controllable mechanism.
  • Known terminals work with a ballast. Each of the ballasts consumes power even when the terminal is turned off, i. when the switching state of the terminal is "off". With a plurality of terminals, this quiescent current adds up to considerable sizes. In particular, environmental damage and costs can be avoided if the energy consumption of a busbar system can be reduced. However, a terminal or the associated ballast can not be switched off easily. The control unit of the busbar system would then interpret this as an error. The aim of known arrangements is therefore to lower the quiescent current to the lowest possible value.
  • a group of terminals may also consist of a single terminal. However, it is cheaper if only one switching element is used for several terminals.
  • the terminals and the switching element have a DALI interface, via which a bidirectional data exchange according to the DALI control protocol with the control unit is feasible.
  • the means for generating a control signal, with which the switching element restores the interrupted connection to the voltage source, acted upon by the signals of a timer By a timer, the switching element can interrupt the connection to the power source, for example, at work in the evening after work and restore morning before starting work again. Then at night, no energy is consumed from the power source.
  • the means for generating a control signal with which the switching element restores the interrupted connection to the voltage source can alternatively or additionally be acted upon by the signals of a button for switching on and off terminals. Then the connection to the voltage source is switched on again manually. With a suitable circuit can be taken in particular to ensure that the connection to the voltage source is interrupted as soon as the last terminal is turned off. So if all devices have the switching state "off", the connection is automatically interrupted.
  • FIG. 1 shows a section of a generally designated 10 busbar system.
  • the busbar system 10 comprises two data lines 22 and 24 (data bus) and three power cables 26, 28 and 30, and a neutral conductor 32.
  • a DALI controller 34 is provided between the terminals 12, 14, 16, 18 and 20 and the controller 34 on the one hand and a (not shown) power supply on the other hand switches 36 and 38 are provided. With the switches 36 and 38, the connection can be interrupted or restored. The switches 36 and 38 are controlled by a DALI actuator 40.
  • the actuator 40, the terminals 12, 14, 16, 18 and 20 and the controller 34 are connected to the data lines 22 and 24 via a suitable interface. Each connected device has an address via which it communicates with the other connected devices.
  • the terminals 12, 14 and 20 form a first group. They are connected via the power cable 26 to the power supply. The connection is controlled by the switch 36.
  • the terminals 16 and 18 form a second group. They are connected via the power cable 28 to the power supply. This connection is controlled by the switch 38.
  • the actuator 40 and the controller 34 are connected via the power cable 30 to the power supply. No switch is required here.
  • the switching element consisting of actuator 40 and switches 36 and 38 now operates as follows.
  • the controller 34 receives a signal from all terminals 12, 14 and 20 of the first group that it is "off"
  • the controller sends via the bus 22, 24 a control command to the actuator to open the switch 36.
  • the connection to the voltage source is completely interrupted. There is no quiescent current. The energy consumption is zero.
  • the controller 24 When the controller 24 receives a signal from all terminals 16 and 18 of the second group that it is "off”, the controller sends via the bus 22, 24 a control command to the actuator to open the switch 38. Then the energy consumption of the second group from the voltage source is zero.
  • the controller By actuating a button, e.g. is activated simultaneously with a terminal of a manually operable switch, the controller receives the information that the terminal is to be turned on. Then, the controller sends a command to the actuator to close switch 36 again.
  • a button e.g. is activated simultaneously with a terminal of a manually operable switch
  • the operation described above is a load-dependent circuit in which the power supply is interrupted whenever all terminals of a group are turned off. But there is also the possibility of time-dependent circuit. This is always useful if the times when the terminals are switched on, are easy to plan.
  • energy-saving circuit is not limited to the number of groups, the number of terminals or the selection of terminals. Also, the circuit is independent of the control protocol and can be realized with any control commands.
