发明名称 Energy-saving receiver assembly for the wireless reception of data
摘要 A receiver assembly for the wireless reception of data that are modulated onto a carrier signal includes an analog receiver, an evaluating device and a control device. The control device controls the receiver by means of sampling pulses such that the receiver is activated during the sampling pulses and is ready to receive transmission signals and is deactivated during the sampling pauses. The evaluating device generates a data bit sequence from the received signals that are supplied by the receiver during the sampling pulses. The control device is further designed to actuate the receiver between phases having differing sampling frequency ranges in dependence on at least one predefined switching criterion.

主权项 1. A receiver assembly for the wireless reception of data that is modulated onto a carrier signal, the receiver comprising: an analog receiver; an evaluation device; and a control device configured to control the receiver with sampling pulses such that the receiver is switched on and is ready for receiving transmission signals during the sampling pulses and is switched off and receives no transmission signals during the sampling pauses, the evaluation device configured to produce a data bit sequence from the received transmission signals delivered by the receiver during the sampling pulses, wherein the control device is further configured to switch over activation of the receiver between phases of sampling pulses with different sampling frequency ranges based on at least one predefined switching-over criterion, and wherein the switch-over criterion is at least one predefined data sequence that is stored in the evaluation device, wherein, when the data bit sequence matches the predefined data sequence, the evaluation device is configured to deliver a switch-over signal to the control device for changing from a first phase of sampling pulses with a first sampling frequency range in which the receiver is prepared to receive the data sequence to a second phase of sampling pulses with a second sampling frequency range in which the receiver receives usable data, the sampling ratio between sampling pulses and sampling pauses in the first phase being between 1:1,000,000 and 1:10,000 and in the second phase being between 1:5,000 and 1:125.
