Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 4, the automatically controlled precursor operation system redundant apparatus of a kind of excavator, comprise controller, automatically controlled pilot control valve group, electromagnetic switch valve group, electromagnetic proportional valve group and the display for showing automatically controlled pilot system emergency maneuver interface, described electromagnetic switch valve group and electromagnetic proportional valve group are electrically connected with controller, and described controller carries out communication by CAN one and automatically controlled pilot control valve group; Described display carries out communication by CAN two and controller; Controller, according to collecting automatically controlled pilot control spool parameter after calculating, exports+24V and controls electromagnetic switch valve group, exports and controls electromagnetic proportional valve group with the pwm signal of automatically controlled pilot control valve proportion of composing.
Described automatically controlled pilot system emergency maneuver interface comprises for controlling the sign of automatically controlled pilot control valve prescription to action, and for realizing automatically controlled pilot control valve group cyclic switching, performing automatically controlled pilot control valve prescription to action and function cancellation function button.Described display, for showing pilot valve mode of operation, carries out emergency operation to automatically controlled precursor operation system simultaneously.
As shown in Figure 2, described automatically controlled pilot control valve group comprises right foot pedal, left and right walking bi-pedal, left foot pedal, right handles and left handle, and each automatically controlled pilot control valve is for controlling excavator corresponding main control valve spool pilot pressure.
As shown in Figure 3, described left and right handle has X+, X-, Y+, Y-four-way operating function, and left and right foot pedal has Y+, Y-bidirectional operation function.
As shown in Figure 4, described display is divided into viewing area and non-display area, described left and right handle, left and right foot pedal, the sign of left and right walking bi-pedal shows in the display area, and described function button comprises F1, F2, F3, F4, F5 and F6, and is arranged on non-display area.Viewing area is according to from left to right (being " left side " on the left of Fig. 1, right side is for " right side ") order be defined as that left handle indicates, right handles indicates, left threading indicates, left and right bi-pedal indicates and right threading sign successively, each sign only has an energy selected, indicate selected after, with solid border with do not choose sign to distinguish, and carry out cyclic switching by function button F1; Function button F2 is defined as and performs pilot control valve X+ direction action key, function button F3 is defined as and performs pilot control valve Y+ direction action key, function button F4 is defined as and performs pilot control valve Y-direction action key, and function button F5 is defined as and performs pilot control valve X-direction action key.Left handle or right handles indicate selected after, function button F2 ~ F5 button all can be triggered, and left threading, left and right bi-pedal or right threading indicate selected rear function button F3, F4 button and can be triggered, and function button F6 is defined as function and cancels button.
Certainly also can be touch screen displays, each automatically controlled pilot control valve indicates and function button F1 ~ F6 all shows in touch screen displays, operates more convenient.
The course of work: controller receives automatically controlled pilot control valve group signal, and output switching signal, pwm signal control corresponding electromagnetic switch valve and electromagnetic proportional valve after computing, thus control excavator action.Under excavator is in non-faulting state, driver handles corresponding automatically controlled pilot control valve according to action demand, direction and the manipulation scaling signal of automatically controlled pilot control valve are delivered to controller by CAN one, controller exports+24V and electrically connects corresponding electromagnetic switch valve, output pwm signal triggering electromagnetic proportional valve, the function of the pilot control valve corresponding to excavator performs, by CAN two, automatically controlled pilot control valve signal is delivered on display with Time Controller, the display of display man-machine interface is by pilot valve, steering and the manipulation ratio handled.If a certain control crank breaks down, multiple handle break down or CAN one Communications failure time, controller judges automatically controlled pilot control valve device fault, and send instruction activation display electric control handle emergency maneuver man-machine interface by CAN two, in man-machine interface, definition represents the automatically controlled pilot control valve of difference in functionality, each automatically controlled pilot control valve mark carries out cyclic switching by the function button of definition, and ensure to only have a control crank selected, driver can according to equipment fault situation and action demand, length pins watch-dog directionkeys up and down, push button signalling is transferred to controller by CAN two by watch-dog, thus have activated the function of control crank corresponding to it.
In excavator manipulation of physical, breaking down for left handle, the utility model is described in further detail.
The left revolution of the corresponding excavator in the X+ direction of left handle, the corresponding excavator right-hand rotation in X-direction, the corresponding excavator boom in Y+ direction are put outward, the corresponding excavator boom adduction in Y-direction, controller carries out scan round with the fixed cycle to CAN one, if left handle breaks down, then controller cannot receive the control signal of left handle, if now driver wishes that handling left handle carries out turning round or dipper action, excavator is without response.Controller still cannot receive CAN one data of left handle after multiple intermittent scanning, then judge left handle generation equipment fault, and send instructions to display by CAN two, display activates automatically controlled pilot system emergency maneuver interface.Driver chooses left handle to indicate by function button F1, this duration pins F2 key, the signal that left handle X+ direction is triggered is transferred to controller by CAN two by display, controller exports+24V to left revolution electromagnetic switch valve 301, export a fixing pwm signal to left revolution electromagnetic proportional valve 501, excavator performs left revolution, and after function button F2 upsprings, left revolution stops.If pin equally F5 key excavator to carry out right-hand rotation, pin F3 key excavator boom and put outward, pin F4 key excavator boom adduction.
If when right foot pedal, left foot pedal, right handles CAN one break down, of the present utility modelly realize principle, method of operating breaks down consistent with left handle.
