[0029] Please refer to figure 1 ,in, figure 1 It is a schematic diagram of the work flow of the first embodiment of the method for controlling the automatic car dumping of a diesel locomotive provided by the present invention. The automatic control method for dumping a diesel locomotive includes the following steps:

[0030] S1: Human-computer interaction for confirmation, add a car dump function interface on the locomotive display screen interface, through human-computer interaction, this interface can independently choose to enter the car dump mode or exit the car dump mode, the diesel engine indicator valve is opened, and the display screen and computer control The system defines the communication interface and defines the interaction information of the dumping mode;

[0031] S2: Enter the car dump mode, the microcomputer system receives the display screen car dump mode request information, and enters the car dump mode;

[0032] S3: Lubricate the diesel engine system, th...

[0054] Please refer to figure 2 , based on the first embodiment of the present application to provide a control method based on diesel locomotive automatic car dumping, the second embodiment of the present application proposes another method based on diesel locomotive automatic car dumping control. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0055] Specifically, the difference between the control method based on the automatic ditching of diesel locomotives provided by the second embodiment of the present application is that the method of automatic ditching control based on diesel locomotives also includes detecting the surroundings while alarming in step S3. Detection system, the detection system includes a thermal imaging sensing system for detecting the surroundings of the locomotive, a delay system for controlling the microco...

Abstract

The invention provides an automatic uncoupling control method for an internal combustion locomotive. The automatic uncoupling control method for the internal combustion locomotive comprises the following steps that S1, confirmation is conducted through man-machine interaction, an uncoupling function interface is additionally arranged on a locomotive display screen interface, the interface can autonomously select to enter an uncoupling mode or exit the uncoupling mode through man-machine interaction, a diesel engine indicator valve is opened, a display screen and a microcomputer control system define a communication interface; and uncoupling mode interaction information is defined; S2, an uncoupling mode is executed, and uncoupling mode request information of the display screen is received by a microcomputer system; according to the automatic uncoupling control method for the internal combustion locomotive, control is conducted through interaction of the microcomputer control system and the display screen, pre-lubrication control over an engine oil system and control over rotation of the crankshaft driven by an oil engine starting device are achieved, the safe, efficient and convenient control method is provided for uncoupling operation of the diesel locomotive through judgment of checking of the number of turns of the crankshaft. Manual operation is reduced, and automatic control over the uncoupling process is achieved.

Description

technical field [0001] The invention relates to the technical field of diesel locomotives, in particular to a control method for automatic dumping of diesel locomotives. Background technique [0002] Diesel locomotive is a locomotive that uses the internal combustion engine as the driving force and drives the wheels to rotate through the transmission device. According to the fuel type of the internal combustion engine on the locomotive, most of the diesel locomotives used on my country's railways are equipped with diesel engines. [0003] Generally, when a traditional diesel locomotive is shut down for more than 24 hours after the diesel engine is overhauled or replaced internally, according to the maintenance requirements, it is necessary to open the indicator valves of each cylinder of the diesel engine, and use the starter motor to drive the crankshaft to rotate when there is no fuel injection in the cylinder. , to get rid of impurities such as oil and water accumulated i...
