System and method for cleaning and/or inspecting a pipeline

A system for cleaning and/or inspecting a pipeline, comprising:

• a hose;
• a working device connected to one end of the hose for carrying out the cleaning and/or inspection and comprising a sensor device set up to detect sensor data representing a movement direction of the working device in the pipeline with respect to an opening through which the hose is introduced into the pipeline;
• a hose drum onto which the hose can be wound up and from which the hose can be unwound;
• a motor coupled to the hose drum and formed to rotate the hose drum in a first direction of rotation so as to wind the hose onto the hose drum;
• and
• a control device connected in a signal-carrying manner to the working device and motor and set up:
• to determine the movement direction of the working device in the pipeline on the basis of the sensor data and to output to the motor a first control signal which causes the motor to rotate the hose drum in the first direction of rotation to wind up the hose when the determined movement direction of the working device corresponds to a predetermined first movement direction,
• wherein the first movement direction corresponds to a movement of the working device towards the opening through which the hose is introduced into the pipeline;
• wherein the sensor device comprises an optical sensor that is an imaging sensor of a camera of the working device, the imaging sensor being set up to output image data as the sensor data;
• and wherein the control device is set up to determine the movement direction by way of the image data outputted by the imaging sensor.
