Problems solved by technology

[0004] 1. Replace the governor spring, but the replacement work is more complicated, and due to technical reasons, it cannot be guaranteed that the problem can be solved immediately after replacement
[0005] 2. According to the debugging of the locomotive, modify the number of driving steps according to the gear position on the original CPU software, increase or decrease the pre-tightening force of the governor spring, and increase or decrease the speed of the diesel engine accordingly. However, when the number of locomotives is large, it is easy to cause the computer software to The version is chaotic and inconvenient to maintain i

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0032] Such as figure 1 Shown, a kind of adaptive diesel engine step speed regulation method of the present invention, its specific implementation process is as follows:

[0033] In the present embodiment, suppose the maximum number of gears M of the diesel engine is 16 gears, the empirical theoretical estimation value of the initial driving steps of the stepper motor at this gear is 900 steps, after the diesel engine starts, when the gears change, The adaptive speed regulation process of the stepper motor is:

[0034] Adjust the gear position of the diesel engine controller to N gear, follow the steps below to obtain the initial driving steps of the stepper motor and drive the stepper motor:

[0035] S1.1a. Read the value U stored in the stepping speed regula...

Abstract

The invention discloses a self-adaptive step-by-step speed regulation method for a diesel engine. The method comprises the follow steps: S1, obtaining the initial driving step number of a stepping motor of the diesel engine in the current gear, and driving the stepping motor to the initial driving step number; S2, monitoring the actual speed of the diesel engine, and judging whether the error between the actual speed and the preset target speed of the diesel engine at the current gear is larger than the preset threshold value or not; if yes, going to S3; if not, going to S4; S3, calculating the driving step number of the stepping motor, adjusting the driving step number of the stepping motor of the diesel engine in the current gear, and going to S2; S4, storing the driving step number of the stepping motor of the diesel engine in the current gear to a step-by-step speed regulation system for the diesel engine. When the speed of the diesel engine does not conform to the standard, the method can quickly and accurately automatically regulate the speed, and meet the overall performance requirements of the diesel engine, the control effect is good, debugging is convenient , and the diesel engine is economic and durable.

Description

technical field [0001] The invention relates to the field of diesel engine speed regulation control, in particular to an adaptive stepping speed regulation method for diesel locomotive diesel engines. Background technique [0002] At present, the domestic microcomputer-controlled stepping speed regulation system of diesel engine is mainly through the controller to adjust the gear position of the diesel engine. , so as to change the pre-tightening force of the speed regulating spring, so that the equipment connected to the rear end of the speed regulating spring will change accordingly, and the position of the speed regulating fuel supply rod will control the fuel supply of the diesel engine to achieve the purpose of adjusting the speed of the diesel engine. [0003] In actual control, because the speed regulating spring is a nonlinear tower spring with similar parameters, the parameters of different speed regulating springs are not exactly the same, resulting in errors in th...
