In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the embodiments of the invention.
Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. These exemplary embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It should be appreciated that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art. In the drawings, the same reference numerals are used to designate the same elements for the sake of clarity, and thus a description thereof will be omitted.
The following detailed description is directed to specific embodiments.
The invention firstly provides a speed regulation control device for a diesel engine and a speed regulation control method matched with the speed regulation control device. The speed regulation control device and the speed regulation control method are particularly suitable for marine diesel engines.
As shown in fig. 1, in a preferred embodiment, the throttle control apparatus 10 includes a power generation mode setting element 20, a first propulsion mode setting element 30, a second propulsion mode setting element 40, an acceleration and deceleration setting element 50, and a control module 60. The power generation mode setting element 20, the first propulsion mode setting element 30, the second propulsion mode setting element 40, and the acceleration and deceleration setting element 50 are all coupled to the control module 60. The control module 60 is also coupled to an electronically controlled fuel injection system 70. Wherein the power generation mode setting element 20, the first propulsion mode setting element 30, and the second propulsion mode setting element 40 are used for a user to input a set rotational speed in various application modes of the diesel engine, and the acceleration/deceleration setting element 50 is used for a user to input acceleration/deceleration information (for example, an amount by which an increase or decrease in rotational speed of the diesel engine is required). The control module 60 has control software built therein. After the control module 60 receives the information from the setting elements, the control software processes the information to control the electronic control fuel injection system 70 to work, so as to achieve the purpose of controlling the rotation speed of the diesel engine.
It will be appreciated that the throttle control apparatus 10 further includes a display module for displaying man-machine interaction information.
As shown in fig. 2, in a preferred embodiment of the present invention, the speed regulation control method of the diesel engine processes the rotational speeds (i.e., set rotational speeds) set by the user in a plurality of application modes (e.g., a power generation application mode and a propulsion application mode) to obtain a target rotational speed, and calculates the current actual rotational speed (i.e., the current rotational speed) of the diesel engine in real time, calculates the current oil amount of the diesel engine according to the deviation between the target rotational speed and the current rotational speed by using a PID (proportional-differential integral) closed-loop controller, and further adjusts the oil injection amount of the electronically controlled fuel system to control the rotational speed of the diesel engine.
Specifically, the power generation mode setting element 20 is used for a user to set the set rotational speed of the diesel engine in the power generation application mode in the form of a dot value. The power generation mode setting element 20 includes an idle rotation speed setting element 21 and a rated rotation speed setting element 22. The idle rotation speed setting element 21 and the rated rotation speed setting element 22 may each be configured as a key element such as a button, a touch screen, a touch film key, or the like, for example. When the idle rotation speed setting element 21 is operated by the user, the idle rotation speed setting element 21 issues a short-time trigger signal, which the control module 60 receives, thereby setting the set rotation speed to the idle rotation speed. When the user operates the rated rotation speed setting element 22, the rated rotation speed setting element 22 issues a short-time trigger signal, which the control module 60 receives, thereby setting the set rotation speed to the rated rotation speed. The idle speed and the rated speed are preset values.
The first propulsion mode setting element 30 is used for a user to set the set rotational speed of the diesel engine in the propulsion application mode in the form of a dot value. The first propulsion mode setting element 30 includes an in-line rotational speed setting element 31 and an out-of-line rotational speed setting element 32. The in-line rotation speed setting element 31 and the out-of-line rotation speed setting element 32 may each be configured as a key element, for example, a button, a touch screen, a touch film key, or the like. When the user operates the joint rotation speed setting element 31, the joint rotation speed setting element 31 issues a short-time trigger signal, and the control module 60 receives the trigger signal, thereby setting the set rotation speed to the joint rotation speed. When the user operates the discharge rotation speed setting element 32, the discharge rotation speed setting element 32 issues a short-time trigger signal, which the control module 60 receives, thereby setting the set rotation speed to the discharge rotation speed. Wherein, close row rotational speed and take off row rotational speed and all be the default.
The second propulsion mode setting element 40 is used for a user to set the set rotational speed of the diesel engine in the propulsion application mode in the form of a continuous analog quantity. The second propulsion mode setting element 40 may be configured, for example, as a knob element, which may be continuously rotated. When the knob is rotated, the rotation angle thereof corresponds to an analog signal of 4-20mA, and the control module 60 can calculate a set rotation speed according to the analog input signal of 4-20mA, that is, can set the rotation speed in the whole working range of the diesel engine through the knob. The smaller the current corresponding to the second propulsion mode setting element 40, the lower the set rotational speed of the diesel engine, and the larger the current corresponding to the second propulsion mode setting element 40, the higher the set rotational speed of the diesel engine. It will be appreciated that the second propulsion mode setting element 40 may also be configured as a continuously adjustable slider-type adjustment element, for example.
In a preferred embodiment, the control module 60 is configured to perform the steps of:
s10, acquiring the current rotating speed of a diesel engine;
s20, acquiring a set rotating speed of a diesel engine;
s30, determining a target rotating speed according to the set rotating speed;
s40, adjusting the fuel injection quantity of the electronic control fuel injection system according to the difference value between the target rotating speed and the current rotating speed, so as to adjust the rotating speed of the diesel engine.
In step S10, the control module 60 may calculate the current rotational speed of the diesel engine by using various modes such as the monitoring signal of the sensor, the voltage signal, the current signal, and the like.
In step S20, the control module 60 acquires the set rotational speed of the diesel engine in the power generation application mode from the power generation mode setting element 20; alternatively, the set rotational speed of the diesel engine in the propulsion application mode is obtained from the first propulsion mode setting element 30 or the second propulsion mode setting element 40. Wherein in the propulsion application mode the vessel is configured to set the rotational speed either by the first propulsion mode setting element 30 or by the second propulsion mode setting element 40. Since the power generation application mode and the propulsion application mode of the diesel engine do not exist at the same time, only one of the power generation mode setting element 20, the first propulsion mode setting element 30, and the second propulsion mode setting element 40 is operable in a specific application mode.
The power generation mode setting element 20 and the first propulsion mode setting element 30 described above can be implemented to set a certain commonly used fixed value of the set rotational speed by a one-touch operation. In order to adapt to different loads, the rotation speed of the diesel engine needs to be adjusted within a certain range, and the acceleration and deceleration setting element 50 is used for a user to input acceleration and deceleration information. Specifically, the acceleration/deceleration setting element 50 is used for a user to set the set rotation speed of the diesel engine in such a manner as to increase or decrease the current rotation speed on the basis of the current rotation speed. The acceleration and deceleration setting element 50 includes an acceleration setting element 51 and a deceleration setting element 52. When the user operates the acceleration and deceleration setting element 50, step S20 further includes: the control module 60 acquires the set rotational speed from the acceleration/deceleration setting element 50.
Specifically, the acceleration setting element 51 is configured to set a set rotational speed, that is, a desired rotational speed increase of the diesel engine, in such a manner as to increase the current rotational speed on the basis of the current rotational speed; the deceleration setting element 52 is used to set the set rotational speed in such a way that the current rotational speed is reduced, i.e. a rotational deceleration of the diesel engine is desired, on the basis of the current rotational speed. The acceleration setting element 51 and the deceleration setting element 52 may each be configured as a key element, such as a button, a touch screen key, or the like, for example.
Preferably, when the acceleration key 51 is pressed: if the time period T for pressing the acceleration key 51 is smaller than or equal to the preset pressing time period Tp, setting the rotating speed to be equal to the sum of the current rotating speed and the first variation D1; if the time period T for which the accelerator button 51 is pressed is longer than the preset pressing time period Tp, the rotation speed is set to be equal to the sum of the current rotation speed and [ (T-Tp) ×D2+D1], wherein D2 is the second variation. For example, the preset pressing time period is 1s, the first variation D1 is 1rpm, and the second variation D2 is 50rpm. If the current rotation speed is 500rpm, if the acceleration key 51 is pressed for a short time (i.e. the pressing time period does not exceed the preset pressing time period of 1 s), the set rotation speed is 501rpm, and the set rotation speed is that the first variation D1 is increased on the basis of the current rotation speed. If the current rotation speed is 500rpm, if the accelerator button 51 is pressed for 3.5 seconds, the rotation speed set in the first 1s is changed to 501rpm, and then the rotation speed set in the second 2.5s is gradually increased from 501rpm to 626rpm, and the rotation speed set is increased by (T-Tp) ×d2+d1= (3.5-1) ×50+1=2.5× 50+1=126 rpm on the basis of the current rotation speed of 500 rpm.
Preferably, when the deceleration key 52 is pressed: if the duration T of the depression of the deceleration key 52 is less than or equal to the preset depression duration Tp, the set rotation speed is equal to the current rotation speed minus the first variation D1; if the time period T for which the speed reduction key 52 is pressed is longer than the preset pressing time period Tp, the set rotation speed is equal to the current rotation speed minus [ (T-Tp) ×D2+D1], where D2 is the second variation. For example, the preset pressing time period is 1s, the first variation D1 is 1rpm, and the second variation D2 is 50rpm. If the current rotation speed is 500rpm, if the deceleration key 52 is pressed for a short time (i.e., the pressing time period does not exceed the preset pressing time period of 1 s), the set rotation speed is 499rpm, and the set rotation speed is reduced by the first variation D1 based on the current rotation speed. If the current rotation speed is 500rpm, if the speed reduction button 52 is pressed for 3.5 seconds, the rotation speed set in the first 1s is changed to 499rpm, and then the rotation speed set in the second 2.5s is gradually reduced from 499rpm to 374rpm, and the rotation speed set is reduced by (T-Tp) ×D2+D1= (3.5-1) ×50+1=2.5× 50+1=126 rpm on the basis of the current rotation speed of 500 rpm.
Preferably, the second variation D2 is larger than the first variation D1. Thus, the user can conveniently set the set rotation speed by pressing the key for a long time.
As described above, the second propulsion mode setting element 40 can realize a function of continuously setting the rotation speed of the diesel engine in an analog quantity, similar to the effect of the acceleration/deceleration setting element 50. To optimize the control flow, when the vessel is configured to set the rotational speed by the second propulsion mode setting element 40, the control module 60 is configured to: if the second propulsion mode setting element 40 fails, the function of the acceleration and deceleration setting element 50 is masked; if the second propulsion mode setting element 40 fails, the acceleration/deceleration setting element 50 is enabled, and acceleration/deceleration processing is performed on the basis of the set rotational speed set by the second propulsion mode setting element 40 before the failure occurs. For example, with a current rotational speed of 2000rpm, the user wishes to increase the rotational speed to 2100rpm, and thus operates the second propulsion mode setting element 40 (e.g., rotates the knob), a malfunction occurs when the second propulsion mode setting element 40 rotates to a position corresponding to a rotational speed of 2050rpm, the alarm device alarms to inform the user that the second propulsion mode setting element 40 malfunctions, and the control module 60 enables the acceleration and deceleration setting element 50, the user may continue to set the set rotational speed using the acceleration and deceleration setting element 50 (e.g., the acceleration setting element 51). At this time, the user may set the set rotational speed to 2100rpm on the basis of 2050rpm by the acceleration setting member 51. The user may adjust the diesel engine speed by the acceleration and deceleration setting member 50 until the second propulsion mode setting member 40 is unrepaired. When the user adjusts the rotation speed again using the acceleration and deceleration setting element 50, the set rotation speed is set on the basis of the current rotation speed.
Based on the power generation mode setting element 20, the first propulsion mode setting element 30, the second propulsion mode setting element 40, and the acceleration/deceleration setting element 50, the user can complete the work of setting the set rotational speed. The control module 60 will further process the set rotational speed to obtain a target rotational speed.
To ensure safe operation of the diesel engine, the control module 60 is configured to control a range of target rotational speeds. Preferably, the control software is provided with a target rotation speed upper limit value and a target rotation speed lower limit value, wherein the target rotation speed upper limit value is larger than the target rotation speed lower limit value.

To avoid vibration damage at the critical rotational speed, the control software preferably disables the diesel engine from rotating at the critical rotational speed Nc. Specifically, the control software is provided with a rotation speed forbidden region range which is not less than +/-5% Nc, namely the upper limit value of the rotation speed forbidden region is greater than or equal to Nc (1+X), and the lower limit value of the rotation speed forbidden region is less than or equal to Nc (1-X), wherein 5% < = X <100%.
As shown in fig. 3, during the rotational speed increasing process of the diesel engine, the step S30 includes: when the set rotation speed is less than the rotation speed exclusion zone lower limit value, the target rotation speed is set to the set rotation speed; when the set rotation speed is less than the rotation speed exclusion zone upper limit value and greater than or equal to the rotation speed exclusion zone lower limit value, the target rotation speed is set to the rotation speed exclusion zone lower limit value; when the set rotational speed is greater than or equal to the rotational speed exclusion zone upper limit value, the target rotational speed is set to the set rotational speed. I.e. during acceleration of the diesel engine, the speed exclusion zone is crossed.
As shown in fig. 4, during the rotational speed reduction process of the diesel engine, step S30 includes: when the set rotation speed is greater than the rotation speed exclusion zone upper limit value, the target rotation speed is set to the set rotation speed; when the set rotation speed is less than or equal to the rotation speed exclusion zone upper limit value and greater than the rotation speed exclusion zone lower limit value, the target rotation speed is set to the rotation speed exclusion zone upper limit value; when the set rotation speed is less than or equal to the rotation speed exclusion zone lower limit value, the target rotation speed is set to the set rotation speed. I.e. during deceleration of the diesel engine, the speed exclusion zone is crossed.
In the present invention, at most two exclusion zones may be provided, i.e. at most two critical rotational speeds, a first critical rotational speed Nc1 and a second critical rotational speed Nc2, where Nc2> Nc1.
Step S30 includes: in the rotational speed increasing process of the diesel engine, when the set rotational speed is smaller than the first rotational speed exclusion zone lower limit value, the target rotational speed is set to the set rotational speed, when the set rotational speed is smaller than the first rotational speed exclusion zone upper limit value and greater than or equal to the first rotational speed exclusion zone lower limit value, the target rotational speed is set to the first rotational speed exclusion zone lower limit value, and when the set rotational speed is greater than or equal to the first rotational speed exclusion zone upper limit value, the target rotational speed is set to the set rotational speed; in the speed reduction process of the diesel engine, when the set rotation speed is greater than the first rotation speed exclusion zone upper limit value, the target rotation speed is set to the set rotation speed, when the set rotation speed is less than or equal to the first rotation speed exclusion zone upper limit value and greater than the first rotation speed exclusion zone lower limit value, the target rotation speed is set to the first rotation speed exclusion zone upper limit value, and when the set rotation speed is less than or equal to the first rotation speed exclusion zone lower limit value, the target rotation speed is set to the set rotation speed. Wherein the upper limit value of the first rotation speed forbidden zone is larger than the lower limit value of the first rotation speed forbidden zone. The upper limit value of the first rotation speed forbidden region is larger than or equal to Nc1 (1+X), and the lower limit value of the first rotation speed forbidden region is smaller than or equal to Nc1 (1-X), wherein Nc1 is the first critical rotation speed of the diesel engine, and 5% <=X <100%.
Step S30 includes: in the rotational speed increasing process of the diesel engine, when the set rotational speed is smaller than the second rotational speed exclusion zone lower limit value, the target rotational speed is set to the set rotational speed, when the set rotational speed is smaller than the second rotational speed exclusion zone upper limit value and is greater than or equal to the second rotational speed exclusion zone lower limit value, the target rotational speed is set to the second rotational speed exclusion zone lower limit value, and when the set rotational speed is greater than or equal to the second rotational speed exclusion zone upper limit value, the target rotational speed is set to the set rotational speed; in the speed reduction process of the diesel engine, when the set rotation speed is greater than the second rotation speed exclusion zone upper limit value, the target rotation speed is set to the set rotation speed, when the set rotation speed is less than or equal to the second rotation speed exclusion zone upper limit value and greater than the second rotation speed exclusion zone lower limit value, the target rotation speed is set to the second rotation speed exclusion zone upper limit value, and when the set rotation speed is less than or equal to the second rotation speed exclusion zone lower limit value, the target rotation speed is set to the set rotation speed. The upper limit value of the second rotation speed forbidden zone is larger than the lower limit value of the second rotation speed forbidden zone, and the lower limit value of the second rotation speed forbidden zone is larger than the upper limit value of the first rotation speed forbidden zone. The upper limit value of the second rotation speed forbidden region is larger than or equal to Nc2 (1+Y), and the lower limit value of the second rotation speed forbidden region is smaller than or equal to Nc2 (1-Y), wherein Nc2 is the second critical rotation speed of the diesel engine, and 5% <=Y <100%.
To this end, the control module 60 has been able to determine a target rotational speed for the diesel engine.
In step S40, the control module 60 preferably adjusts the fuel injection amount of the electronically controlled fuel injection system through the PID closed loop controller according to the difference between the target rotational speed and the current rotational speed, so as to adjust the rotational speed of the diesel engine to make the rotational speed of the diesel engine reach or approach the target rotational speed.
To ensure a smooth variation in the rotational speed of the diesel engine, the control module 60 preferably controls the rate of change of the rotational speed of the diesel engine (i.e., the rate of change of the rotational speed) in step S40. When the target rotational speed is greater than the current rotational speed (i.e., when a rotational speed increase of the diesel engine is required): if the target rotational speed is less than or equal to the first rotational speed, the control module 60 is configured to vary the rotational speed of the diesel engine from the current rotational speed to the target rotational speed at a first rate (e.g., 25 rpm/s); if the target rotational speed is greater than the first rotational speed, less than or equal to a second rotational speed, the control module 60 is configured to vary the rotational speed of the diesel engine from the current rotational speed to the target rotational speed at a second rate (e.g., 30 rpm/s), wherein the second rotational speed is greater than the first rotational speed and the second rate is greater than the first rate; if the target speed is greater than the second speed, the control module 60 is configured to vary the speed of the diesel engine from the current speed to the target speed at a third rate (e.g., 35 rpm/s), wherein the third rate is greater than the second rate.
Preferably, in step S40, when the target rotation speed is smaller than the current rotation speed (i.e., when the rotation speed of the diesel engine is required to be reduced): the control module 60 is configured to vary the rotational speed of the diesel engine from a current rotational speed to a target rotational speed at a preset rate of deceleration (e.g., 40 rpm/s).
Fig. 5 to 7 illustrate the above-described control procedure in various application modes.
As shown in fig. 5, in the power generation application mode, when the diesel engine receives a stop command, the set rotational speed is set to 0. If the test mode is adopted, the test rotating speed set by the test software is assigned to the set rotating speed. When the diesel engine is running, the set rotation speed assignment is performed according to the point value input signal of the power generation mode setting element 20, namely: setting the rotation speed assignment to the idle rotation speed when the idle rotation speed contact is valid (the idle rotation speed setting element 21 is operated); the set rotational speed is assigned to the rated rotational speed when the rated rotational speed contact is active (the rated rotational speed setting member 22 is operated).

And then, carrying out safety range limitation and speed exclusion zone crossing control on the set speed set by a key, for example, so as to obtain the final target speed. Finally, the rotation speed of the diesel engine is controlled to be gradually changed from the current rotation speed to the target rotation speed at a proper change rate.
As shown in fig. 6, in the first propulsion application mode, if the diesel engine receives a stop command, the set rotational speed is set to 0. If the test mode is adopted, the test rotating speed set by the test software is assigned to the set rotating speed.

When the acceleration/deceleration contact is active (the acceleration/deceleration setting element 50 is operated), the set rotational speed is obtained according to the case where the acceleration/deceleration setting element 50 is operated. And then, carrying out safety range limitation and speed exclusion zone crossing control on the set speed set by a key, for example, so as to obtain the final target speed. Finally, the rotation speed of the diesel engine is controlled to be gradually changed from the current rotation speed to the target rotation speed at a proper change rate.
As shown in fig. 7, in the second propulsion application mode, if the diesel engine receives a stop command, the set rotational speed is set to 0. If the test mode is adopted, the test rotating speed set by the test software is assigned to the set rotating speed. In operation of the diesel engine, the set rotational speed is assigned based on the analog input signal from the second propulsion mode setting element 40. If the second propulsion mode setting element 40 fails, the acceleration/deceleration setting element 50 is enabled to set the set rotational speed. And then limiting the safety range and controlling the passing of the rotation speed forbidden zone by the set rotation speed set by the setting element to obtain the final target rotation speed. Finally, the rotation speed of the diesel engine is controlled to be gradually changed from the current rotation speed to the target rotation speed at a proper change rate.
