Railway train approaching alarm system and alarm method

Abstract

The invention provides a railway train approaching alarm system and an alarm method. The alarm system comprises an alarm signal trigger unit, an alarmed signal receiving unit, an alarm signal receiving and driving unit, an alarm unit and an alarmed signal trigger unit, wherein the alarm signal trigger unit and the alarmed signal receiving unit are arranged at an alarm point, the alarm signal receiving an driving unit, the alarm unit and the alarmed signal trigger unit are arranged at a construction site. In the invention, the GSM-R (Global System for Mobile Communications-Railway) network, a bell alarm and a bell identification circuit are utilized to form a closed loop alarm system and a method, with the working personnel at the alarm point as a main node, so as to satisfy the principle of failure guiding safety to the maximum extent. The alarm system provided by the invention has the advantages of low cost and higher degree of automation, achieves a failure guiding safety function, and can reduce labor intensity. The alarm system not only is suitable for railway lines covered by the GSM-R network, but also is suitable for areas along the railway lines, which are covered by common mobile networks.

Description

technical field [0001] The invention relates to railway construction protection equipment, in particular to a train approaching alarm system and an alarm method used at a railway track construction site, which are used for sending a train approaching signal to railway construction personnel when a train approaches the railway track construction site. Background technique [0002] Reconstruction, maintenance and construction of railway lines open to traffic have always been a very important task of the railway department. Anyone who understands this work knows that the safety and security of the construction site of the railway line opening to traffic is a very important issue. The normal regulation is: before the construction, the construction unit should make a reasonable estimate of the time required for the construction, and then apply to the superior management department, and work at the designated time after the superior's approval. However, due to the busy transporta...

Problems solved by technology

The problem with this method is that the labor intensity of the notifiers is high, and the requirements for the number of notifiers and their sense of responsibility are relatively high.

For this reason, their implementation has brought serious problems of high cost, especially in the environment where wireless communication is blocked, they either cannot realize the alarm function or have to set up a communication network separately, which brings extremely high costs.
