Specific embodiment
Understand to make the object, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments, to this
Invention is further elaborated.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention,
The range being not intended to restrict the invention.
Unless otherwise defined, all technical terms and scientific terms used herein are led with belonging to the technology of the present invention
The normally understood meaning of technical staff in domain is identical, and used term is intended merely to retouch in the description of the invention herein
State the purpose of specific embodiment, it is not intended that in the limitation present invention.
As shown in Figure 1, a kind of method for controlling number of revolution of paver diesel engine, including display 1, maximum (top) speed switch 2,
Economic speed switch 3, controller 4, diesel engine controller 5 and throttle potentiometer 6；
The controller 4 connects respectively with display 1, maximum (top) speed switch 2, economic speed switch 3 and diesel engine controller 5
It connects, the diesel engine controller 5 is connected with throttle potentiometer 6；
The maximum (top) speed switch 2 is used to convey maximum (top) speed instruction to controller 4, and the economic speed switch 3 is used for
Economic speed instruction is conveyed to controller 4；
When the controller 4 receives maximum (top) speed instruction, maximum (top) speed instruction is sent to diesel engine controller 5；
When controller 4 receives economic speed instruction, economic speed instruction is sent to diesel engine controller 5；When controller 4 simultaneously
When receiving maximum (top) speed instruction and economic speed instruction, the controller 4 sends economic speed to diesel engine controller 5 and refers to
It enables；
The diesel engine controller 5 is used to receive the rotary speed instruction signal of the transmission of controller 4 and throttle potentiometer 6 transmits
Throttle potentiometer signal, when diesel engine controller 5 simultaneously receive rotary speed instruction signal and throttle potentiometer signal when, with turn
Fast command signal is preferential, and the input of throttle potentiometer signal is spare.
It is improved as embodiment, when the controller 4 is to the transmission rotary speed instruction of diesel engine controller 5, in a manner of slope
It sends.
As the improvement of embodiment, the display 1 is stored in maximum (top) speed value and economy in controller 4 for modification
Tachometer value, once a damage in maximum (top) speed switch 2 and economic speed switch 3, another still can individually control rotating speed,
Ensure working properly.
As the improvement of embodiment, the controller 4 is connect by CAN lines with diesel engine controller 5, is operated with more just
It is prompt.
As being further improved for embodiment, the model ONE_L4_77 of the display 1；The controller 4, diesel oil
The model of machine controller 5 is respectively EPEC2024.Performance is stablized.
With reference to shown in Fig. 2, maximum is received by controller 4 for the control method of paver diesel engine speed in the present invention
The input signal of speed switch 2 and economic speed switch 3 after controller 4 receives the input signal of maximum (top) speed switch 2, is given
Diesel engine controller 5 sends maximum (top) speed instruction；After controller 4 receives the input signal of economic speed switch 3, to diesel engine
Controller 5 sends economic speed instruction；If controller 4 receives two input signals simultaneously, sent out to diesel engine controller 5
Warp let-off Ji rotary speed instruction, the i.e. input signal of economic speed switch 3 are preferential.
Controller 4 when sending rotary speed instruction to diesel engine controller 5, is sent by way of slope, such as：It is maximum
When throttle rotating speed is 2000, it is not to directly transmit 2000, but increases from each program circulating period of idle speed value 800 about 10ms
5 turns are stepped up to 2000, realize being stepped up for diesel engine speed, so as to fulfill protection diesel engine, one is only received in two seconds
The signal of secondary setting throttle, accordingly even when the frequent movement that shake will not cause throttle occur in throttle button or knob.Its
In, the par_n in attached drawing 2 is assigned a value of 200, because program operation a cycle is 10ms, it is 2s to run 200 periods, in this way
Namely 2s programs receive a setting value, protect diesel installation.
The CAN tach signals and throttle potentiometer signal, CAN signal that the reception controller 4 of diesel engine controller 5 is sent are excellent
First, the input of throttle potentiometer signal is spare, i.e.,：When CAN signal communication is normal, CAN throttles, throttle potentiometer signal can only be used
In vain；During CAN signal communicating interrupt, in the case where not powering off, switch to the control of throttle potentiometer signal；CAN signal communication is extensive
When multiple, in the case where not powering off, throttle potentiometer signal ceases to be in force automatically, and switchs to CAN throttles, and rotating speed is with current CAN signal
Subject to.
The present invention is easy to operate, and reliability is high, uses economy；It can save energy noise reduction in the construction process, improve paver
Reliability has preferable social and economic benefit.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent replacement or improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
