Abstract

The invention relates to a scanning type beam detection device, comprising a beam emitter, a beam receiver and two scanning supports; the scanning supports are arranged on the head and the part ends of an isolation area in parallel and sliding manners; two scanning supports are an emission scanning support and a reception scanning support; the reception scanning support is provided with the beam receiver; the emission scanning support is provided with the beam emitter and the beam refractor; the emission scanning support and the reception scanning support synchronously slide; the beam emitted by the beam emitter is directly irradiated into the beam receiver or is irradiated into the beam receiver after being refracted by the beam reflector; and the beam sweeps across the whole isolation zone for detection. The invention realizes the detection area whole coverage of the isolation area inside and outside the safety boundary of the high speed rail and the urban train, realizes seamless high density detection, and enables the structure to be more reasonable and the cost to be lower. The invention has a safer, effective and reliable protection function, and, in the meantime, is applied in the wide and long isolation channels in other airports, harbors and nuclear plants.

Description

technical field

[0001] The invention relates to the technical field of safety protection and railway safety detection, in particular to a scanning beam detection device and method for high-speed railway and urban railway platforms. Background technique

[0002] There is a safety door (or screen door) device on the platform of high-speed railway and intercity railway. The safety door (or screen door) is similar to the safety door (or screen door) device of the subway, which can prevent passengers from falling off the track while waiting for the train, and the train The danger caused by negative air pressure when passing at high speed can reduce parking delays and driving accidents caused by human beings. However, in order to ensure the safe operation of the train, an isolated area of ​​certain width must be reserved between the train and the safety door (or screen door), and this area is also an emergency passage for passengers when the train stops.

[0003] Generally speaki...
