Abstract

The invention relates to a method for analysing an automation system, in particular a driver assistance system in a vehicle, an emulator for at least partial virtual operation of an automation system of an installation, and a system for analysing an automation system of an installation. An environment scenario for the installation, in particular a traffic scenario, is simulated. A response signal to be detected by at least one environment sensor, in particular an ultrasound response signal, is derived from the perspective of the at least one environment sensor on the basis of the simulated environment scenario. The response signal is output to the at least one environment sensor by means of an emulator, wherein the at least one environment sensor generates sensor data on the basis of the output response signal. In addition, the automation system and/or the installation are/is operated by means of the generated sensor data and preferably further sensor data of real and/or simulated sensors.

First claim

What is claimed is:

1. An emulator for at least partial virtual operation of an automation system of an installation having at least one environment sensor, comprising:
a receiver configured to receive signals emitted by the at least one environment sensor;
a signal processing device configured to generate response signals on a basis of the received signals emitted by the at least one environment sensor;
a transmitter configured to transmit the response signals to the received signals emitted by the at least one environment sensor; and
a signal-absorbing chamber lined with a signal-absorbing material that forms an absorptive region configured to absorb signals, wherein the receiver and the transmitter are arranged in the signal-absorbing chamber.

2. A method for analyzing an automation system of an installation having at least one environment sensor, the method comprising:
outputting the response signals to the at least one environment sensor via the emulator in accordance with claim 1 , wherein the at least one environment sensor generates sensor data on a basis of the response signals;
via a computing device:
simulating an environmental scenario for the installation;
deriving the response signals to be detected by the at least one environment sensor based on the simulated environmental scenario from the perspective of the at least one environment sensor;
operating the automation system and/or the installation using the generated sensor data; and
simulating the at least one environment sensor by means of a sensor model,
wherein the at least one simulated environment sensor virtually detects the simulated environmental scenario and the response signals are derived on the basis of the virtually detected simulated environmental scenario.

3. The method according to claim 2 , wherein a signal for virtually detecting the simulated environmental scenario is simulated by the sensor model along with the response signals on a basis of physical models.

4. The method according to claim 2 , wherein the automation system and/or the installation is/are operated on a test bench or in the field by the simulated environmental scenario.

5. The method according to claim 2 , wherein when outputting the response signals, the emulator takes into account received signals emitted by the at least one environment sensor.

6. The emulator according to claim 1 , wherein the signal-absorbing chamber comprises an opening through which signals emitted by the at least one environment sensor can enter the emulator and/or in which or in front of which the at least one environment sensor can be arranged.

7. A system for analyzing an automation system of an installation having environment sensors, comprising:
a computing device capable of running software for simulating an environmental scenario for the installation; and
the emulator in accordance with claim 1 , which is configured to output a signal to the environment sensors based on the simulated environmental scenario from a perspective of the environment sensors.

8. The system according to claim 7 , further comprising:
a central control; and
a data interface for receiving setpoints signals and/or control parameters from the central control,
wherein the central control and the emulator are configured to communicate with one another, and wherein the central control is configured to control an output of response signals at a plurality of emulators on the basis of the simulated environmental scenario, wherein the plurality of emulators includes the emulator.

9. The system according to claim 8 , wherein the central control defines a frequency, an amplitude, and a response reaction time of a signal for each emulator of the plurality of emulators.

10. A system for analyzing an automation system of an installation having at least one environment sensor, comprising:
the emulator in accordance with claim 1 , which is configured to output the response signals to the at least one environment sensor, wherein the at least one environment sensor generates sensor data on a basis of the response signals; and
a computing device configured for:
simulating an environmental scenario for the installation;
deriving the response signals to be detected by the at least one environment sensor based on the simulated environmental scenario from the perspective of the at least one environment sensor;
operating the automation system and/or the installation using the generated sensor data; and
simulating the at least one environment sensor by a sensor model,

wherein the at least one simulated environment sensor virtually detects the simulated environmental scenario and the response signals are derived on the basis of the virtually detected simulated environmental scenario.
