Embodiment Construction

[0047] figure 1 A schematic diagram of the device according to the invention in a building power grid is shown. Here, a distributor 3 is connected to the network access 18, which distributes the alternating current to each consumer group 4, 4'in the building. Each consumer group 4, 4'has a safety device 12 that separates the consumer group from the grid in a dangerous situation. Immediately after the safety device 12, a receiver 2 is arranged in each consumer group 4, 4', which is arranged before the grid voltage is provided to the consumer 5 via the wire 13. A transmitter 1 is provided directly before the consumer 5, which can apply a current signal to the AC voltage grid. When multiple consumers 5 are connected in the same consumer group 4, 4', each consumer can have its own transmitter.

[0048] in figure 2 A simplified equivalent circuit diagram of a device with two consumer groups 4, 4'and a distributor 3 according to the present invention is shown in. Safety device 12 (...

Abstract

The invention relates to a method for the data transmission from an emitter (1) to a receiver (2) in an AC voltage network, comprising a distributor (3) and at least one user group (4) with one or several users (5), wherein the emitter (1) feeds a signal to the AC voltage network by means of a power source (6).

Description

Technical field [0001] The invention relates to a method for transmitting data from a transmitter to a receiver in an AC voltage network and a device used therefor. Background technique [0002] A variety of different methods for transmitting data in an AC voltage network have been disclosed in the prior art. For example, US5491463 describes a power line communication (PLC) method for individual control of equipment, in which addresses and control data are transmitted during the zero-crossing period of the AC voltage of the power supply. The disadvantage here is that in this method, in each case, an own 120 kHz generator is required to generate the short pulse signal and the receiver must be equipped with a relatively expensive detector circuit. In addition, a large parallel capacitance is not conducive to optimized transmission. [0003] EP134910A2 discloses a method that defines different bit types by zeroing or blanking of different lengths of the supply voltage, and can use a...
