ATP and LKJ integrated vehicle-mounted equipment

Abstract

The invention relates to ATP and LKJ integrated vehicle-mounted equipment. A vehicle-mounted host operates an ATP control sub-module and an LKJ control sub-module; information sent by the ATP vehicle-mounted peripheral equipment is received by the ATP control sub-module, then is subjected to format conversion and is stored in a cache region, and is periodically read by the LKJ control sub-module;the ATP control sub-module receives the operation level conversion instruction and selects to output a control instruction of the ATP control sub-module or the LKJ control sub-module to the train; theATP vehicle-mounted peripheral equipment comprises a human-computer interface unit, an ATP vehicle-mounted sensor unit and an ATP vehicle-mounted antenna unit; and the human-computer interface unit can switch to set ATP operation parameters for the ATP operation interface or switch to set LKJ operation parameters for the LKJ operation interface according to the instruction of the ATP control subunit, and automatically switch to different vehicle control interfaces according to the operation level in the operation process. The LKJ vehicle control function is integrated into the ATP main control unit, a vehicle does not need to be transformed, and the installation space and cost are saved.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a vehicle equipment integrating ATP and LKJ. Background technique [0002] On-board equipment is a kind of signal control equipment that must be installed on the train, and it plays a key role in ensuring driving safety. The basic principle of vehicle control is to obtain the position of the target point of vehicle control (corresponding to the closing signal in front, the track section occupied by the train in front or other dangerous points) from the ground equipment according to the line data stored by itself or obtained from the ground equipment, and calculate the control position. to prevent the train from exceeding the allowable speed of the line, crossing the signal machine or colliding with the vehicle in front, such as figure 1 shown. If the driver does not perform the deceleration operation, the on-board equipment will give a sound alarm or output normal bra...

AI Technical Summary

Problems solved by technology

[0010] The 350km / h EMUs are only equipped with CTCS-3 ATP equipment, and no LKJ equipment is installed, so the 350km / h EMUs cannot operate normally on ordinary speed railways

In the future, if the 250km / h EMUs are equipped with LKJ-15 and ATP equipment at the same time, more space needs to be reserved
