Abstract

The invention discloses a diesel engine digital regulation and control device and a regulation and control method achieved through the diesel engine digital regulation and control device. The device comprises a speed regulating drive main circuit, a shaping circuit, a core processor and an input and output device. The core processor is used for segmented PID control. Input signals of the shaping circuit are revolution speed transducer signals, and output signals of the shaping circuit are square wave revolution speed signals. The output end of the shaping circuit is connected with an external interruption pin of the core processor, and an I/O port of the core processor is connected with the input and output device. Signals output by a PWM output pin of the core processor are connected to the speed regulating drive main circuit, and a speed regulating output terminal TS of the speed regulating drive main circuit outputs voltage for regulating a diesel engine accelerator. The device has the advantages of being compact in structure, low in power consumption, high in accuracy, good in speed control performance, high in safety and convenient to use.

Description

technical field [0001] The invention relates to a diesel engine speed control device and a control method thereof, belonging to the field of digital speed control, in particular to a diesel engine digital speed control device and a control method thereof. Background technique [0002] At present, diesel generators usually use analog speed control devices, and the analog speed controllers mainly have the following problems: 1. Due to the use of many separate components, the power consumption is large and the reliability is reduced; 2. In the traditional In the analog speed controller, the potentiometer knob is usually used to set the speed. Therefore, it will eventually affect the control accuracy of the speed, and it is difficult to achieve precise speed control; 3. The control method with fixed PID parameters is usually used. Under different operating intervals and operating states, variable parameter control cannot be realized. Contents of the invention [0003] The tec...
