Locomotive as well as automatic linkage hooking control method and device

Abstract

The invention discloses an automatic linkage hooking control method used for a locomotive. The method comprises the following steps of obtaining the initial state of a traction locomotive; when the initial state meets a linkage hooking starting condition, detecting a distance between the traction locomotive and a back trailer; comparing a current distance value with at least two preset distance intervals corresponding to different speed ranges respectively, determining a preset distance interval to which the current distance value belongs, and controlling the traction locomotive to run in the car speed range corresponding to the preset distance interval; when the traction locomotive meets a linkage hooking condition, applying braking to and carrying out linkage hooking operation on the traction locomotive. The invention also discloses an automatic linkage hooking control device used for the locomotive. The invention also discloses the locomotive comprising the automatic linkage hooking control device. By using the automatic linkage hooking control method, linkage hooking operation steps can be simplified; the linkage hooking impact is reduced; the riding comfort of a driver is improved; the operation time wasted due to the failure of linkage hooking is saved.

Description

technical field [0001] The invention relates to the technical field of rail transit engineering, in particular to an automatic linkage control method. In addition, the present invention also relates to an automatic coupling control device; in addition, the present invention also relates to a locomotive with the automatic coupling control device. Background technique [0002] In the field of rail transit, rail rolling stock is connected to each other by couplers to transmit traction to achieve traction. However, at present, during the coupler coupling process between rail rolling stock (hereinafter referred to as "locomotive") and the rear car, due to the limited field of view of the locomotive, it is often necessary to complete the coupling process through the cooperation of ground personnel or the experience of the driver. The operation is complicated, and the connection operation has a large impact; if the connection fails, it needs to be re-connected, which is time-consu...

Problems solved by technology

However, at present, during the coupler coupling process between rail rolling stock (hereinafter referred to as "locomotive") and the rear car, due to the limited field of vision of the locomotive, it is often necessary to complete the coupling process through the cooperation of ground personnel or the experience of the driver.

The operation is complicated, and the impact of the linking operation is large; if the linking fails, the linking operation needs to be re-linked, which is time-consuming and laborious
