Railway line group operation safety protection device and method

Abstract

The invention belongs to the field of railway safety protection and management, and particularly relates to a safety protection device and method for field operation personnel in the operation process of a railway line group, and the device comprises a protection point collector, an operation area terminal, a protection point terminal and an operation personnel safety helmet. The protection point collector obtains track circuit information by using a current transformer, outputs vehicle-existence / non-vehicle signal data, outputs field protection personnel evacuation indication and outputs collection fault indication in combination with vibration sensor redundancy, and is connected with the wireless device; the operation area terminal is used for receiving the signal data and the fault indication output by the protection point collector, realizing bidirectional simplex voice communication and receiving wireless information of station protection personnel; the protection point terminal directly sends train approaching information; and according to the invention, a safe direct-connection information network is constructed in an area for safety management in a construction range by combining the characteristics of multiple railway construction points and long lines, so that the safety of operators is effectively ensured, and effective safety management of railway group construction and maintenance operation is realized.

Description

technical field [0001] The invention belongs to the field of railway safety protection and management, in particular to a safety protection device and method for on-site workers during group operations on railway lines. Background technique [0002] With the rapid increase of China's railway speed several times and the application of a large number of new technology equipment, the running density of trains has increased sharply, and the construction skylight time has been continuously shortened. However, the construction of railway lines is complicated, with large construction work areas, long lines, poor working environment conditions, and poor construction conditions. Short period and so on. The existing construction safety protection is mainly based on civil air defense, supplemented by radio communication. Usually station guards are set up in the station, and on-site guards are set up at both ends of the construction area. When the train approaches the construction area,...
