Abstract
The present invention provides a kind of excavator start-up and shut-down control method, includes being positioned proximate to switch on the pilot handle of excavator；Judge operator hand whether close to excavator pilot handle, be closed it is described close to switch, otherwise disconnect it is described close to switch；When it is described be closed close to switch when, the control system is by the control of engine speed of excavator to scheduled working speed；When it is described be disconnected close to switch after, further judge it is described whether execute action in the given time close to switch, be to keep intact, otherwise the control system is by the control of engine speed of excavator to scheduled idling speed.By the pressure switch being positioned proximate on pilot handle in switch in place prior art, advantage of lower cost, and flame-out problem, engine is caused to be not easy to stop working there is no time delay.
Description
Technical field
The present invention relates to a kind of engineering truck control method, especially a kind of excavator start-up and shut-down control method.
Background technology
Excavator is a kind of engineering machine being widely used in all kinds of occasions such as construction, mine excavation and construction of water conservancy works
Tool vehicle.Excavator is during stopping operation, although stand-by time interval is not grown, but needs frequently to be waited in short-term
Machine, in order to reduce oil consumption, reducing noise and extend the service life of engine, excavator is when standby, it usually needs reduces
Throttle makes engine enter idling mode, this process generally use idling start-up and shut-down control technology is controlled.
The following method of existing excavator idling start-up and shut-down control technology generally use：When engine is kept in the unloaded state
After a certain period of time, control engine speed is reduced to idling speed；When engine loads, automatically controlled engine rotating speed returns to
The working speed of setting；In this process, it is according to pressure switch to the judgement of engine light condition or stress state
The induction of pilot pressure is realized, i.e., when all pilot operated mechanisms return to middle position, pilot pressure keeps one in zero
After the section time, engine speed is automatically lowered to idling speed, when pressure switch has monitored that pilot pressure is more than zero,
With regard to restoring engine speed to target operation rotating speed.Although this excavator idling start-up and shut-down control method can significantly reduce
Oil consumption reduces noise and extends the service life of engine, still, for incuding the pressure switch price of pilot pressure more
Costliness, the cost is relatively high, and detects pilot pressure by pressure switch and control the work turn that engine speed returns to setting again
This fast process easily causes flame-out there is regular hour delay.
In view of this, the application excavator start-up and shut-down control method conducts in-depth research, there is this programme generation then.
Invention content
Flame-out excavator start-up and shut-down control side is not easily caused the purpose of the present invention is to provide a kind of advantage of lower cost and
Method.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of excavator start-up and shut-down control method, includes the following steps：
S1 is positioned proximate to switch on the pilot handle of excavator, described logical close to the control system of switch and excavator
News connection；
S2 starts excavator, judge operator hand whether close to excavator pilot handle, be closed it is described close
Otherwise switch disconnects described close to switch；
S3, when it is described be closed close to switch when, the control system is by the control of engine speed of excavator to scheduled
Working speed；After the close switch is disconnected, it is dynamic further to judge whether the close switch executes in the given time
Make, be to keep intact, otherwise the control system is by the control of engine speed of excavator to scheduled idling speed.
As an improvement of the present invention, the close switch includes oscillator, switching circuit and the amplification being connected with each other
Output circuit.
As an improvement of the present invention, described to have close to switch for adjusting induction detecting distance and induction sensitivity
Regulating device.
As an improvement of the present invention, in step s3, the predetermined time is -6 seconds 3 seconds.
As an improvement of the present invention, in step s3, scheduled working speed is 2200 revs/min, scheduled idle
Fast rotating speed is 900 revs/min.
Above-mentioned technical proposal is used, the invention has the advantages that：
1, by the pressure switch being positioned proximate on pilot handle in switch in place prior art, cost is relatively
It is low, and cause flame-out problem, engine to be not easy to stop working there is no time delay.
2, control method of the invention is easy to implement, can be not only used for the excavator of new production, can also be by existing
Some excavators are transformed applied in existing excavator.
Description of the drawings
Fig. 1 is that the flow of excavator start-up and shut-down control method of the present invention opens up complement.
Specific implementation mode
The present invention is described further in the following with reference to the drawings and specific embodiments.
Excavator start-up and shut-down control method provided in this embodiment, includes the following steps：
S1 is positioned proximate to switch on the pilot handle of excavator, this is communicated close to the control system of switch and excavator
Connection.Pilot handle and control system are all possessed component or system on existing excavator, and and will not be described here in detail.
Include oscillator, switching circuit and the amplification output circuit being connected with each other close to switch, and has close to switch and use
In the regulating device for adjusting induction detecting distance and induction sensitivity, this kind of close switch can be directly that purchase obtains from market,
In the present embodiment, close to switch model LP-18N8C or LP-18P8C, this feels close to cylindrical, diameter 18mm is switched
Should distance 8mm, power as DC10-30v, be a kind of three line inductance approach switches of direct current having two kinds of output of NPN and PNP.
Certainly, step S1 needs to be previously-completed when in use.
S2, as shown in Figure 1, starting excavator, by the hand close to switch real-time judge operator whether close to excavator
Pilot handle, be then be closed close to switch, otherwise disconnect close to switch.In other words, no matter the engine of excavator is in
Normal operating conditions or idling mode, no matter the hand of operator is close to pilot handle or far from pilot handle, close to switch
Whether the hand of operator will be judged close to pilot handle, and executes respective action.
S3, when being closed close to switch, control system by the control of engine speed of excavator to scheduled working speed,
The working speed can be set according to actual needs, it is preferred that in the present embodiment, scheduled working speed is 2200 revs/min
Clock.
After being disconnected close to switch, it is dynamic whether control system further judges to execute in the given time close to switch
Make, be to keep intact, do not change the engine speed of excavator, otherwise control system is by the control of engine speed of excavator
It to scheduled idling speed, can frequently be changed to avoid the engine speed to excavator in this way, be conducive to improve and excavate
The service life of the engine of machine.Likewise, above-mentioned predetermined time and scheduled idling speed can be according to actual needs
Setting, it is preferred that in the present embodiment, the predetermined time is -6 seconds 3 seconds, and scheduled idling speed is 900 revs/min.
The present invention is described in detail above in conjunction with specific embodiment, but embodiments of the present invention and is not only limited
In the above embodiment, those skilled in the art can make various modifications according to the prior art to the present invention, such as above-mentioned implementation
It is changed to other kinds of sensing device etc. close to switch in example, these are all within the scope of protection of the present invention.
