Positioning precision.
For example, with reference to Fig. 3, the control output electricity of 30 pairs of the controller electro hydraulic valve 40 under normal mode
Flow valuve INormallyCalculation formula can be such as following formula：
INormally=c* (I1-I0)/(b-a)+I0；
And under jog mode, the control output current value I of 30 pairs of the controller electro hydraulic valve 40It is micro-Calculation formula can
Such as following formula：
IIt is micro-=c* (I1-I0)/[k*(b-a)]+I0；
Wherein, a, I0Output valve and corresponding proportioning valve current value when respectively the rocking bar reaches deadband boundaries, b,
Output valve and corresponding ratio valve port standard-sized sheet current value when I1 is respectively the rocking bar range, c are the current stroke of rocking bar
Corresponding output valve, and c ∈ [a, b], k are fine motion coefficient, and k>1.
Fine motion coefficient k can be selected according to actual needs, and such as value is two or more, and fine motion can be achieved accordingly
Adjustment precision more trickle under pattern.
In addition to the Wireless remote control of wireless remote controller, conduit squeezes into control system and can further include car
Actuation means 70 (referring to Fig. 2) are carried, vehicle-mounted actuation means 70 are connected with the signal of controller 30,30 pairs of the controller is from institute
The signal for stating vehicle-mounted actuation means 70 and the reception of the wireless receiver 20 is detected, and is confirming the vehicle-mounted actuation means
70 when having signal output, turns down the operational order from the wireless receiver 20, and confirming the vehicle-mounted manipulation
When the no signal of device 70 is exported, the operational order from the wireless receiver 20 is adopted.
Vehicle-mounted actuation means 70 can realize manipulation request of the operating personnel on tunneling chassis, and in order to improve safety
Performance, uses vehicle-mounted actuation means and controls preferential safety regulation in the present embodiment.When vehicle-mounted actuation means have vehicle-mounted
When manipulation signal is sent, no matter whether wireless remote controller sends wireless manipulation signal, or the wireless operating signal generation sent
Which kind of operational order of table, adopts all without by controller, only when vehicle-mounted actuation means do not have signal output, can just adopt and
The operational order corresponding to wireless operating signal sent from wireless remote controller.It so can effectively prevent control signal
Confusion, improves the security of system.
In order to improve homework precision, squeeze into the embodiment of control system, can also add in conduit of the present utility model
