The common start and stop of engineering machinery control in this way:When needing to start, ignition switch is allocated to ON grades by operator, and vehicle supplies
Electricity, then START grades are allocated to, engine start;When needing flame-out, ignition switch is allocated to flame-out shelves, engine misses again.The control
System processed not can effectively prevent the bad operating habit of operator, and reliability is not high, and usually will appear cannot start, stop working
Situation.
Invention content
Goal of the invention:The utility model is that above-mentioned disadvantage of the existing technology is overcome to propose, is intended to provide a kind of knot
Structure novelty, safe and reliable start-stop control system.
Technical solution:A kind of start stop system of engineering machinery, including button switch, starting relay and oil cut-off valve relay
Device, the button switch control the starting relay, oil-break valve relay;The starting relay is inputted to starter motor to be started
Signal, engine start;The oil-break valve relay inputs oil-break signal, engine misses to oil cut-off valve;The start stop system
Further include intermediate relay and clean boot relay;When engine need to start, button switch export enabling signal through centre after
Electric appliance is to clean boot relay, after clean boot relay receives clean boot signal, inputs and starts to starting relay
Signal, engine start;When engine need to stop working, button switch exports misfire signals through intermediate relay to oil cut-off valve relay
Device, engine misses.
Preference, for the work of effectively control intermediate relay, the start stop system further includes the time relay, when described
Between the control signal of relay be derived from generator, the control signal of the intermediate relay is derived from the time relay.
Preference, for the realization of time relay function is effectively ensured, the delay pickup time of the time relay is 3
± 1 second.
Preference further includes latch-in relay to effectively prevent the bad operating habit of operator, the start stop system,
The control signal of the latch-in relay is derived from button switch, the latch-in relay, the time relay respectively alone to
The intermediate relay input control signal.
Advantageous effect:The utility model effectively prevent operator not by the logical relation between single system element
Good operating habit, accuracy rate is high, easy to operate, securely and reliably.
Description of the drawings
Fig. 1 is the principles of the present invention schematic diagram;
Fig. 2 is the flow diagram of the utility model.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of start stop system of engineering machinery, including button switch S, starting relay J1, centre
Relay J2, time relay J3, clean boot relay J4, oil-break valve relay J5 and latch-in relay J6.When described
Between the control signal of relay J3 be derived from generator, the control signal of the latch-in relay J6 is derived from button switch S, described
Latch-in relay J6, time relay J3 are respectively alone to the intermediate relay J2 input control signals.Engine need to open
When dynamic, button switch S outputs enabling signal connects through intermediate relay J2 to clean boot relay J4, clean boot relay J4
After clean boot signal, clean boot relay J4 is attracted work, while inputting enabling signal to starting relay J1, opens
Motor type relay J1 is attracted work, engine start;When engine need to stop working, button switch S exports misfire signals through intermediate relay
Device J2 is to oil-break valve relay J5, engine misses.It is opened since the start stop system of the utility model only has while receiving button
Close the enabling signal of S and another clean boot signal, engine ability effectively start, to which operator and engineering machine be effectively ensured
The safety of tool periphery personnel.
Button switch S described in the utility model is self-resetting switch, including one group of normally opened contact.After engine start, hair
Motor is started to work, and time relay J3 is attracted work to the intermediate relay J2 input control signals, intermediate relay J2
Make, if operator presses a button switch S, oil-break valve relay J5 again at this time) it is attracted work, engine normally stops working;If
Operator presses always button switch S at this time, and oil-break valve relay J5 is equally attracted work, engine misses.Engine misses
Afterwards, generator, which is stopped, one section of buffer time, then can have residual electricity in system, and latch-in relay J6 is promoted to maintain to inhale
For a period of time, if pressing button switch S always, latch-in relay J6 can keep the attracting state of itself to conjunction state on one side,
On one side to the intermediate relay J2 input control signals, intermediate relay J2 is attracted work, to which oil-break valve relay J5 inhales
Work is closed, engine keeps flameout state, until after release button switch S, can just enter next start and stop and recycle, effectively prevent
The appearance of repeatedly starting and stopping phenomenon.
Relay described in the utility model is all common compact relay, at least one group of normally opened contact, rated current
At least 30A.Different engines, idling speed is different, it sometimes appear that starter motor has rotated, but rotating speed is not up to idling and turns
Speed, generator have worked, and engine is also not actuated at this time.To prevent that the appearance of problem and different operation person press button switch S here
The delay pickup time of time length problem, the time relay J3 is 3 ± 1 seconds, can effectively ensure that engine normally starts.
The function of latch-in relay J6 can effectively prevent engine start or press button switch S always after stopping working and form repeatedly starting and stopping
Phenomenon, to protect engine.
Although be described in detail above to the utility model in conjunction with the embodiments, the technology people of the technical field
Member it is understood that without departing from the purpose of the present invention, can also above-described embodiment be changed or be changed,
It still falls within the protection scope of the present utility model.
