Description

Title of the invention

[0001] System module for detecting the use of playback devices via power difference measurement with wireless communication Technical field

[0002] The invention relates to a modular current measurement system, in particular for the automated detection of the operating status of playback devices (e.g. media players, game consoles, receivers) in the field of television research.

[0003] The measurement is performed via socket modules with wireless communication. State of the art

[0004] In existing television research systems, it is often unclear whether a playback device is actually being used or is only in standby mode.

[0005] Furthermore, some measuring devices generally lack solutions for detecting external devices. Object of the invention

[0006] The object of the invention is to provide a modular system that reliably detects the actual operating state of playback devices and transmits this wirelessly to a central module, which in turn communicates with a measuring device via a cable connection.

[0007] The goal is automated, accurate detection of the active use of individual devices. Solution to the task

[0008] The solution is achieved through the following characteristics: • Power measurement modules that are connected between the power outlet and the respective playback device and record the power consumption • The modules analyze the difference between standby and operating power (start-up) • Each current measurement module has an interface for wireless communication. • All modules connect to a central module that processes the received data. • This central module communicates with a measuring device in real time via a cable connection. Example of implementation

[0009] Several adapter plugs with built-in current sensors are plugged into the wall socket. The playback device (e.g., streaming box) is plugged into the adapter. The modules continuously measure the current flow. Based on stored threshold values, it is detected whether the device is active or in standby mode.

[0010] This information is transmitted wirelessly to a central module that monitors all power meters. The central module then forwards the status data via a cable connection to a higher-level measuring device, which automatically detects which input devices are currently in active use.
