At present in industry, most of engineering machinery is single operator seat manipulation, and electronic parking control is seldom able to achieve double It is controlled while operator seat.Also, double operator seat controls require to realize：1, any one operator seat should all can control staying for complete machine Vehicle braking and releasing braking, and by another operator seat, currently whether parking is not influenced；2, complete machine automatic braking after complete machine power-off. Therefore, just need to be able to achieve the parking braking system of double operator seat controls to the engineering machinery of double operator seats control.
Summary of the invention
It is an object of the present invention to provide it is a kind of be able to achieve double operator seats while the double operator seat parking systems of engineering machinery that control Autocontrol system, to overcome engineering machinery parking braking control system in the prior art that can only realize lacking for single operator seat manipulation It falls into.
Realization that the present invention adopts the following technical solutions：
The double operator seat parking braking control systems of engineering machinery of the present invention, including master starts switch, main power source is mutual Lock relay, main power relay, main brake switch, pair starts switch, auxiliary power interlock relay, auxiliary power relay, pair Brake switch, braking switching relay, braking electromagnetic valve and battery, the master start switch control battery and pass through main power source The normally-closed contact of interlock relay gives main power relay coil power supply, and the main power relay normally opened contact is opened with main brake Connection connects, and the pair starts switch control battery and gives auxiliary power relay line by the normally-closed contact of auxiliary power interlock relay Circle power supply, the auxiliary power relay normally open contact are connect with secondary brake switch, the coil termination of the braking switching relay Enter the contact of auxiliary power relay normally open, the normally opened contact of the braking switching relay is connect with secondary brake switch, the system The normally-closed contact and main brake switch of dynamic switching relay connect；The coil-end of the main power source interlock relay accesses auxiliary power The coil-end of relay normally open；The normally opened coil-end of the coil-end access main power relay of the auxiliary power interlock relay.
Insurance is connected on the battery output lead.
The braking electromagnetic valve circuit is connected with emergency stop switch, and the both ends of the emergency stop switch are separately connected system Moving electromagnetic valve and battery terminal negative.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention uses power-off brake strategy, and many condition meets, and complete machine could release braking, and security performance is high；
(2) present invention realizes the non-interfering completion parking braking of two operator seats, can effectively prevent maloperation；
(3) the complex controls element such as unused controller of the present invention, design economy, control effect are good, market competition advantage Obviously.
Detailed description of the invention
Fig. 1 is circuit diagram of the invention；
In figure：1, master starts switch；2, main power source interlock relay；3, main power relay；4, main brake switchs；5, it protects Danger；6, pair starts switch；7, auxiliary power interlock relay；8, auxiliary power relay；9, secondary brake switch；10, braking switching after Electric appliance；11, braking electromagnetic valve；12, emergency stop switch；13, battery.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1, the double operator seat parking braking control systems of engineering machinery of the present invention, including master start switch 1, main power source interlock relay 2, main power relay 3, main brake switch 4, pair start switch 6, auxiliary power interlock relay 7, Auxiliary power relay 8, secondary brake switch 9, braking switching relay 10, braking electromagnetic valve 11 and battery 13, the main starting Switch 1 controls battery 13 and gives main power relay 3 coil power supply by the normally-closed contact of main power source interlock relay 2, described 3 normally opened contact of main power relay is connect with main brake switch 4, and the pair starts switch 6 control batteries 13 and passes through auxiliary power The normally-closed contact of interlock relay 7 gives auxiliary power relay 8 coil power supply, 8 normally opened contact of auxiliary power relay and secondary system Dynamic switch 9 connects, the normally opened contact of the coil-end access auxiliary power relay 8 of the braking switching relay 10, the braking The normally opened contact for switching relay 10 is connect with secondary brake switch 9, the normally-closed contact of the braking switching relay 10 and main system Dynamic switch 4 connects；The normally opened coil-end of the coil-end access auxiliary power relay 8 of the main power source interlock relay 2；The pair The normally opened coil-end of the coil-end access main power relay 3 of power interlock relay 7.
Further, insurance 5 is connected on 13 output lead of battery.
Further, 11 circuit of braking electromagnetic valve is connected with emergency stop switch 12, the both ends point of emergency stop switch 12 Not Lian Jie 13 cathode of braking electromagnetic valve 11 and battery, after detecting braking system faults, emergency stop switch 12 disconnect, it is whole Mechanism is dynamic.
When in main driving room it is main start switch 1 and get to the position ON when, battery 13 is normal by main power source interlock relay 2 Closed contact gives main power relay 3 coil power supply, and 3 coil of main power relay obtains electric, connects 3 normally opened contact of main power relay Logical, 1 hole location of main brake switch 4 obtains electric；Main brake switch 4 is such as got into the position ON at this time, then passes through braking switching relay 10 normally-closed contact obtains braking electromagnetic valve 11 electric, and complete machine releases braking；Main brake switch 4 is such as got into OFF position at this time, Braking electromagnetic valve 11 powers off, complete machine braking；Though at this time pair start switch 6 and secondary brake switch 9 be located at any position, will not The work of main brake switch 4 is had an impact.
