Stop announcement system and method therefor

A stop announcement system, comprising:

• at least one platform beacon disposed on at least one stop site of a transportation means for identifying a position message of the stop site
• the at least one platform beacon capable of sending a message of position change according to the position change of the transportation means relative to the stop site;
• and
• at least one stop announcement device disposed on the transportation means for receiving the message of position change and sending a corresponding stop announcement message when the transportation means moves into a range of a preset communication distance of the at least one platform beacon;
• wherein the stop announcement message at least comprises a prompt message of entering into the stop site and/or a prompt message of stopping on the stop site and/or a prompt message of leaving the stop site;
• and
• at least one transportation means beacon disposed on the transportation means;
• the transportation means beacon receiving the message of position change sent from the at least one platform beacon, and sending the message of position change to the at least one stop announcement device when the transportation means moves into the range of the preset communication distance of the at least one platform beacon;
• wherein the transportation means comprises N carriages;
• a first carriage to a Nth carriage are sequentially connected from a head to a tail of the transportation means;
• the stop announcement system comprises:
• a plurality of the stop announcement devices respectively disposed in each of the carriages;
• the stop announcement devices disposed in the first carriage to the Nth carriage being a first stop announcement device to a Nth stop announcement device sequentially;
• the first stop announcement device to the Nth stop announcement device sequentially receiving a message of a first position change sent from the at least one platform beacon, and sending a prompt message of entering into the stop site when the first carriage to the Nth carriage sequentially move into the range of the preset communication distance of the at least one platform beacon;
• the first stop announcement device to the Nth stop announcement device sequentially receiving a message of a second position change sent from the at least one platform beacon, and sending a prompt message of stopping on the stop site when the first carriage to the Nth carriage sequentially move into the range of the preset communication distance of the at least one platform beacon, and stop moving;
• and
• the first stop announcement device to the Nth stop announcement device;
• sequentially receiving a message of a third position change sent from the at least one platform beacon, and sending a prompt message of leaving the stop site when the first carriage to the Nth carriage continue to advance from a state of stopping moving to sequentially move out of the range of the preset communication distance of the at least one platform beacon.
