Embodiment Construction

[0047] figure 1 A schematic diagram of an arrangement according to the invention in a building electrical system is shown. In this case, a distributor 3 is connected to the network connection 18, which distributes the alternating current in the building to the individual consumer groups 4, 4'. Each consumer group 4, 4' has a fuse 12, which separates the consumer group from the grid in a dangerous situation. Next to the fuse 12, a receiver 2 is arranged in each consumer group 4, 4', which is arranged before the mains voltage is supplied to the consumer 5 via the line 13. Directly upstream of the consumer 5 is a transmitter 1 which can apply a current signal to the AC voltage network. When several consumers 5 are connected in the same consumer group 4, 4', each consumer can have its own transmitter.

Abstract

The invention relates to a device (1) for modifying an AC voltage, wherein the device (1) comprises an input (1) for connecting to an AC voltage source and an output (3) for connecting to a load circuit. The device (1) comprises an interrupter (15) that is designed such that, within at least one time window (35), the output (3) can be disconnected from the AC voltage source, wherein the time window (35) has a time delay (36) from the zero crossing (40) of the voltage of the AC voltage source. At the output (3), the device comprises a terminator (20) that is designed, in particular together with the interrupter (15), such that the voltage at the output (3) of the device (1) has a predefined or predefinable value (37) in the time window (35). Furthermore, the device (1) comprises a pulse shape generator (8) for generating a predetermined or predeterminable pulse shape, and control means (4) that actuate the terminator (20) and the interrupter (15) such that the voltage curve at the output (3) of the device (1) can be modified according to the pulse shape predetermined by the pulse shape generator (8).

Description

technical field [0001] The invention relates to a method for transmitting data from a transmitter to a receiver in an alternating voltage network and a device therefor. Background technique [0002] Various methods for transmitting data in alternating voltage networks are known in the prior art. For example US5491463 describes a power line communication (PLC) method for individual control of devices, in which address and control data are transmitted during zero crossings of the mains AC voltage. The disadvantage here is that in this method a separate 120 kHz generator is required in each case to generate the burst signal and the receiver has to be equipped with a relatively complex detector circuit. Furthermore, large shunt capacitances are not conducive to optimal transmission. [0003] EP134910A2 discloses a method which defines different bit types by zeroing or blanking of different lengths of the supply voltage and enables detection of the bit type and evaluation of th...
