WIPO Patent Application WO/2022/213551

A1

The present invention relates to the technical field of railway "four electrical" signals, and in particular to a railway bridge disaster protection signal system, which is characterized in that: a disaster monitoring device, a monitoring unit and a bridge disaster monitoring relay are comprised. The disaster monitoring device is connected to the monitoring unit by means of a signal electric cable, and the monitoring unit is connected to the bridge disaster monitoring relay by means of a signal electric cable; the bridge disaster monitoring relay is connected to a train operation control system by means of a cable, and the train operation control system is signally connected to a computer interlocking system; and the computer interlocking system is signally connected to a centralized dispatching system. The present invention has the following advantages: after a bridge monitoring system has detected a disaster that endangers the running safety of a train, the signal system employs a train safety automatic protection measure, enabling the train to promptly decelerate and stop after automatically receiving a stop signal, and bridge disaster alarm information may be automatically sent to a train driver, dispatchers in a dispatching center and station watchmen.
