Portable approach alarm for electric traction train

Abstract

The invention relates to a portable approach alarm for an electric traction train. The approach alarm is applied to the field of safety protection and safety warning for approach of railway electric traction trains. The approach alarm is mainly composed of a sensor module 1, a pre-filtering amplification module 2, a signal acquisition module 3, an embedded control module 4, a voltage follower module 5, a relay module 6, a digital-to-analog conversion module 7, a loudspeaker power amplifying module 8, a pickup 9, a storage module 10, a storage battery 11, a charging module 12, a solar panel 13, a battery indicator 14, a 220V mains supply interface 15 and a loudspeaker 16. A beyond visual range sends warning information to remind constructors to leave lines timely to avoid the train when the train approaches, so that the smooth operation of railway line repair and the personal safety of constructors are guaranteed. According to the portable approach alarm for the electric traction train, an additional transmission channel is not required to be built; and the approach alarm is stable, reliable, low in false alarm rate, convenient to use, low in cost, small in limitation of environmental conditions and capable of being carried about by constructors.

Description

technical field [0001] The invention is applied in the field of railway construction protection equipment and safety warning, and relates to various technical fields such as railway safety production and protection operations, embedded system technology, signal acquisition and processing, and electronic device anti-interference technology, and is specifically an electrified railway The train approaching alarm system and alarm method used on the construction site are used to accurately judge the approaching situation of the train beyond the visual distance when the train approaches the railway track construction site, and when the train approaches, it sends a train approaching warning signal to the railway construction personnel, prompting The construction workers go off the line in time to avoid and clean up on-site tools to ensure the personal safety of maintenance and construction personnel, ensure the normal operation of trains, and improve the safety and efficiency of railw...

Problems solved by technology

However, in actual implementation, there are problems such as the need to set up a separate communication network on site, the equipment is large and difficult to carry, easily affected by natural factors, and high cost, so it has not been widely promoted and applied.
