A vehicle-mounted device integrating atp and lkj

Abstract

The invention relates to a vehicle-mounted device integrating ATP and LKJ. The vehicle-mounted host runs an ATP control sub-module and an LKJ control sub-module; the information sent by the ATP vehicle-mounted peripheral device is received by the ATP control sub-module, and then format-converted and stored in a buffer area. It is read periodically by the LKJ control sub-module; the ATP control sub-module receives the operation level conversion command, and selects to output the control command of the ATP control sub-module or the LKJ control sub-module to the train; the ATP vehicle-mounted peripheral equipment includes a man-machine interface unit, an ATP vehicle-mounted The sensor unit and the ATP vehicle-mounted antenna unit; the man-machine interface unit can switch to the ATP operation interface and set the ATP operation parameters according to the instruction of the ATP control subunit, or switch to the LKJ operation interface to set the LKJ operation parameters, and in the running process according to the operation The level is automatically switched to a different car control interface. The invention integrates the LKJ vehicle control function into the ATP main control unit, does not need to transform the vehicle, and saves installation space and cost.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted equipment, in particular to a vehicle-mounted equipment integrating ATP and LKJ. Background technique [0002] On-board equipment is a kind of signal control equipment that must be installed on trains, and it plays a key role in ensuring driving safety. The basic car control principle is to obtain the position of the car control target point (corresponding to the front closed signal, the track section occupied by the train ahead 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 point. train curve to prevent the train from exceeding the allowable speed of the line, crossing the signal or colliding with the preceding vehicle, such as figure 1 shown. If the driver does not decelerate, the on-board equipment will give a sound alarm or output a common brake or even an emergency brak...

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
