Problems solved by technology

However, the BB65t internal combustion hydraulic transmission locomotive in the prior art requires manual intervention to control the parking position during driving, braking, and coupling actions, that is, manually sending PLC signals to control the movement of the locomotive. At the same time, when the locomotive and the mixed-rail car are connected, due to the inertia of the locomotive, if the speed of the locomotive and the distance between the locomotive and the mixed-rail car are not properly controlled, the locomotive will collide with the mixed-rail car, causing the locomotive to , damage to the mixed iron car, and even production accidents

Embodiment 1

[0115] Embodiment 1: the traveling and parking of locomotive 3.

[0116] When the locomotive 3 is located at the first label 41 of 1#, the automatic operation control component 1 of the locomotive receives the operation command issued by the central control system 2, starts the operation subsystem 11, and the terminal position received by the operation subsystem 11 is the first label 41 of 20# , 1# first tag 41 and 20# first tag 41 are 60m apart. The first distance threshold is set to 12m, the distance between the first tag 41 of 1# and the first tag 41 of 20# is greater than 12m, and the first driving module 111 is started. The acceleration distance of the locomotive 3 to 10km / h is 10.8m, and the braking distance corresponding to the speed of 10km / h is 5m; the acceleration distance of the locomotive 3 to 6km / h is 6.7m, and the speed is 6km / h. The corresponding braking distance is 2.3m; the acceleration distance when the locomotive 3 accelerates to 2km / h is 3.2m, and the brak...

Embodiment 2

[0118] Embodiment 2: Alignment of locomotive 3.

[0119]The locomotive 3 stops before the alignment position (about 30m away from the alignment position), the locomotive automatic operation control component 1 receives the alignment command issued by the central control system 2, starts the alignment subsystem 12, and the alignment subsystem 12 receives the second reading The position information of the second tag 42 read by the writer 32 calculates that the distance between the real-time position of the locomotive 3 and the alignment position is 30m. Take the second distance threshold as 3.4m, and the distance between the real-time position of the locomotive 3 and the alignment position is greater than 3.4m, and the alignment subsystem 12 starts the second driving module 122 to drive the locomotive 3 to run at a constant speed of 2km / h until the second reading When the distance between the position information of the second tag 42 read by the writer 32 and the real-time posit...

Embodiment 3

[0120] Embodiment 3: the connection of locomotive 3. The locomotive 3 stops before the connecting position (4-5m away from the connecting position), the locomotive automatic operation control component 1 receives the connecting command issued by the central control system 2, starts the connecting subsystem 13, and simultaneously starts the third driving module 134 , give locomotive 3 an instruction to accelerate for 600 ms at intervals of 2 s, and control locomotive 3 to run at a speed of about 0.5 km / h, so that locomotive 3 is constantly approaching the connected mixed-rail car. When any sensor in the coupler lock pin sensor 132 installed on the coupler and the vehicle distance detection sensor 133 sends a triggered signal to the locomotive 3, the locomotive automatic operation control assembly 1 issues a power cut and braking command to the locomotive 3 until the locomotive 3 parking. By logically judging the signals of the knuckle sensor 131, the coupler lock pin sensor 13...

Abstract

The invention discloses an autonomous operation control method and device for an internal combustion hydraulic transmission locomotive, and the method comprises the steps: a locomotive automatic operation control assembly (1) receives an operation instruction of a central control system (2), starts an operation subsystem (11), and controls the locomotive (3) to operate to a final position; after the locomotive automatic operation control assembly receives an alignment instruction of the central control system, an alignment subsystem (12) is started, and the locomotive is controlled to move to an alignment position; and after the locomotive automatic operation control assembly receives a coupling instruction of the central control system, a coupling subsystem (13) is started, and the locomotive is controlled to move and be coupled with the torpedo car. Full-automatic operation of the locomotive can be achieved, the control requirements in daily operation such as locomotive operation, coupling and alignment are met, the working intensity of a locomotive driver is reduced, the intelligence and automation level of the locomotive is improved, and a foundation is laid for comprehensive unmanned operation of railway transportation.

Description

technical field [0001] The invention relates to a control method and device for metallurgical railway transportation, in particular to an autonomous operation control method and device for an internal combustion hydraulic transmission locomotive. Background technique [0002] At present, the metallurgical technology railway is equipped with BB65t internal combustion hydraulic transmission locomotive, which is operated by wireless remote control and is mainly used to pull mixed iron cars and undertake the task of transporting molten iron between blast furnaces and steelmaking. [0003] Diesel-hydraulic transmission locomotive is one of the transmission forms of locomotives and the main transmission form before electrification of locomotives. It has the characteristics of simple structure, stable and reliable operation, and easy maintenance. Diesel hydraulic transmission locomotives are powered by diesel engines, and through mechanical transmission mechanisms such as torque co...
