Problems solved by technology

But this device can't meet the shunting operation site of the end line of the dumper in the thermal power plant. This is because: the end line of the dumper is different from the end line of the railway. The platform rails are not purely the end of the line. It is impossible to install a fixed car stopper on the rails in front of the dumper

Embodiment Construction

[0042] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0043] figure 1 It is the layout plan of the site section of the "heavy train line" of the dumper in the power plant. A single dumper is divided into two tracks, the parallel heavy train line and the empty train track. The arrow indicates the direction of locomotive travel.

[0044] Heavy vehicle line: 10 vehicle points (A point), 5 vehicle points (H point), 3 vehicle points (B point), 1 vehicle point (C point), secondary alignment area (CD area), heavy vehicle traction area (DE area), dumper coal unloading area (EF area);

[0045] Empty car line: each empty car is moved to the empty car line through the empty car translation area (FG area). The empty cars are grouped into a row after manual cleaning of coal, and fin...

Abstract

The invention relates to a safety protection system and method for shunting operations at the end of a power plant dumper. The system includes a locomotive identification device, a ground main engine and an on-board main engine; there are multiple locomotive identification devices, which are distributed and arranged near the end of the heavy train track within the area; the locomotive identification device is used to generate the vehicle detection control point signal when the locomotive passes by, and transmit the vehicle detection control point signal to the ground host; the ground host is used to perform the vehicle detection control point signal Encoding, generating locomotive position data, and wirelessly sending the locomotive position data to the on-board host; the on-board host is used to demodulate the locomotive position data, generate locomotive position prompt voice, and prompt the driver on the locomotive to control Quick operation. The invention is an active defense system, which can eliminate the interference of human factors, is safe and reliable, can prevent the locomotive from rushing out of the end line of the dumper, and ensure that the locomotive stops steadily in front of the dumper.

Description

technical field [0001] The invention relates to the field of safety protection of a dumper in a power plant, in particular to a safety protection system and method for shunting operations at the end of a dumper in a power plant. Background technique [0002] At present, the most used safety equipment at the end of the railway (meaning that there is no steel track in front) is the hydraulic buffer sliding car stop device fixed at the end of the line. High, easy installation and maintenance, at the end of the railway line, it can prevent vehicles from rushing out of the track and avoid vehicle derailment. But this device can't meet the shunting operation site of the end line of the dumper in the thermal power plant. This is because: the end line of the dumper is different from the end line of the railway. The platform rails are not purely the end of the line, and it is impossible to install a fixed car stop on the rails in front of the dumper. Contents of the invention [...
