Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, a method for controlling the rotating speed of a diesel engine for a paver comprises a display 1, a maximum rotating speed switch 2, an economic rotating speed switch 3, a controller 4, a diesel engine controller 5 and an accelerator potentiometer 6;
the controller 4 is respectively connected with the display 1, the maximum rotating speed switch 2, the economic rotating speed switch 3 and the diesel engine controller 5, and the diesel engine controller 5 is connected with the throttle potentiometer 6;
the maximum rotating speed switch 2 is used for transmitting a maximum rotating speed instruction to the controller 4, and the economic rotating speed switch 3 is used for transmitting an economic rotating speed instruction to the controller 4;
when the controller 4 receives the maximum rotating speed instruction, the controller sends the maximum rotating speed instruction to the diesel engine controller 5; when the controller 4 receives the economic rotating speed instruction, the controller sends the economic rotating speed instruction to the diesel engine controller 5; when the controller 4 receives a maximum rotating speed instruction and an economic rotating speed instruction at the same time, the controller 4 sends the economic rotating speed instruction to the diesel engine controller 5;
the diesel engine controller 5 is used for receiving the rotating speed instruction signal sent by the controller 4 and the throttle potentiometer signal transmitted by the throttle potentiometer 6, and when the diesel engine controller 5 receives the rotating speed instruction signal and the throttle potentiometer signal at the same time, the rotating speed instruction signal is given priority, and the throttle potentiometer signal is input for standby.
As an embodiment improvement, when the controller 4 sends the rotation speed command to the diesel engine controller 5, the rotation speed command is sent in a ramp mode.
As a modification of the embodiment, the display 1 is used for modifying the maximum rotating speed value and the economic rotating speed value stored in the controller 4, and once one of the maximum rotating speed switch 2 and the economic rotating speed switch 3 is damaged, the other one can still control the rotating speed independently to ensure normal operation.
As the improvement of the embodiment, the controller 4 is connected with the diesel engine controller 5 through a CAN line, so that the operation and the use are more convenient.
As a further improvement of the embodiment, the model number of the display 1 is ONE _ L4_ 77; the models of the controller 4 and the diesel engine controller 5 are EPEC2024 respectively. The performance is stable.
The method for controlling the rotating speed of the diesel engine for the paver is shown in a combined manner in figure 2, and comprises the steps that input signals of a maximum rotating speed switch 2 and an economic rotating speed switch 3 are received through a controller 4, and a maximum rotating speed instruction is sent to a diesel engine controller 5 after the controller 4 receives the input signal of the maximum rotating speed switch 2; after receiving the input signal of the economic rotating speed switch 3, the controller 4 sends an economic rotating speed instruction to the diesel engine controller 5; if the controller 4 receives two input signals simultaneously, an economic rotating speed instruction is sent to the diesel engine controller 5, namely the input signal of the economic rotating speed switch 3 takes precedence.
When sending the rotational speed command to the diesel engine controller 5, the controller 4 sends the rotational speed command in a ramp manner, for example: when the maximum accelerator rotation speed is 2000, 2000 is not directly sent, but the rotation speed of the diesel engine is gradually increased from about 10ms to 5 revolutions per one program operation period of an idle speed value 800 to 2000, so that the diesel engine is protected, and an accelerator setting signal is received only once within two seconds, so that frequent action of the accelerator is not caused even if an accelerator button or a knob shakes. Wherein par _ n in fig. 2 is assigned 200, since the program runs for 10ms for one period and runs for 2s for 200 periods, that is, the 2s program receives a set value to protect the diesel engine device.
The diesel engine controller 5 receives the CAN rotating speed signal and the throttle potentiometer signal sent by the controller 4, the CAN signal is prior, and the throttle potentiometer signal is input for standby, namely: when CAN signal communication is normal, only a CAN throttle CAN be used, and signals of a throttle potentiometer are invalid; when CAN signal communication is interrupted, under the condition of not interrupting power supply, the control is converted into throttle potentiometer signal control; when CAN signal communication is recovered, under the condition of no power failure, the signal of the accelerator potentiometer automatically fails and is converted into a CAN accelerator, and the rotating speed is based on the current CAN signal.
The invention has simple operation, high reliability and economic use; the energy-saving noise-reducing paver has the advantages of saving energy and reducing noise in the construction process, improving the reliability of the paver and having better social and economic benefits.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
