Generation system for generating an image signal, railway signaling system comprising such generation system, associated method and computer program product

Generation system for generating an image signal based on a state of trackside signaling equipment of a railway signaling system, the state being a state among a plurality of predetermined states of the trackside signaling equipment, at least one expected color being associated to each predetermined state, the generation system comprising:

• a receiving module receiving a state signal comprising the state of the trackside signaling equipment;
• a number generator periodically generating a random number, each generation of a random number defining an execution cycle;
• a first channel comprising:
• a first base color module providing, for each execution cycle, a first list comprising a first base color for each expected color, each first base color of the first list being based on the random number corresponding to the execution cycle;
• and
• a first generation module selecting, for each execution cycle, the first base color from the first list corresponding to the execution cycle, based on the state signal, so as to provide a selected first base color;
• a second channel comprising:
• a second base color module providing, for each execution cycle, a second list having a second base color for each expected color, each second base color of the second list being based on the random number corresponding to the execution cycle;
• and
• a second generation module selecting, for each execution cycle, the second base color from the second list corresponding to the execution cycle, based on the state signal, so as to provide a selected second base color;
• a merging module merging, for each execution cycle, a first output signal comprising the selected first base color and a second output signal comprising the selected second base color so as to obtain the image signal, wherein the image signal comprises the expected color associated to the state of the state signal;
• and
• a transmission module transmitting, for each execution cycle, the image signal to a user interface via a data connection.
