Train sensor unit for sensing radio communication based train, train position sensing system, and train position sensing method of the system

摘要

Provided is a train sensor unit for sensing a radio communication based train to transmit train sensing information to a control unit, which includes a sensor unit, a controller unit, and a communication unit. The sensor unit obtains environmental information about an environment in which the train travels. The controller unit determines whether the train is present, based on the obtained environmental information. The communication unit wirelessly transmits the train sensing information to the control unit if the train is present.

1. A train sensor unit comprising:
a sensor unit obtaining environmental information about an environment in which a train travels, wherein the sensor unit comprises a sound sensor and a vibration sensor; a controller unit determining whether the train is detected, based on the obtained environmental information; and a communication unit wirelessly transmitting train sensing information to a control unit if the train is detected, wherein the train sensing information comprises identification information of the train sensor unit, position information of the train sensor unit and information on whether the train is detected, wherein the train sensor unit shares the train sensing information with another train sensor unit through the communication unit, and wherein the controller unit determines that the train is present if a noise measured by the sound sensor is equal to or greater than a reference value and a vibration measured by the vibration sensor is equal to or greater than a reference value.
