In the prior art, all be through manually pressing high low speed walking button, switch to low speed, could solving.This has just proposed higher operation requirements to the staff.
Therefore, provide a kind of can the intelligent walking controller for motor and control method just seem particularly important.
Summary of the invention
The objective of the invention is to overcome in the prior art, can only improve excavating machine running motor adaptive ability through the deficiency of manual switchover.
The present invention provides a kind of intelligent walking controller for motor, wherein, comprising:
High-speed row is walked switch, an end ground connection, and the other end connects controller;
Said controller connects high-speed row and walks electromagnetic valve, and said high-speed row is walked electromagnetic valve series connection running motor;
Measure the pressure sensor of running motor, connect said controller.
Above-mentioned intelligent walking controller for motor, wherein, the number of said pressure sensor is 4.
Above-mentioned intelligent walking controller for motor, wherein, said 4 pressure sensors measurement of left right lateral are respectively walked the oil-feed and the oil outlet of motor.
Above-mentioned intelligent walking controller for motor wherein, also comprises high low speed switching push button, connects said high-speed row and walks switch.
According to another aspect of the present invention, a kind of intelligent walking motor height double speed control method of utilizing above-mentioned intelligent walking controller for motor is provided also, wherein, comprises:
Step 1, whether the detection high-speed row is walked switch closed;
Step 2 is closed closure if high-speed row is left, and then closed high-speed row is walked electromagnetic valve;
Step 3, whether the force value of detected pressures sensor is greater than first threshold;
Step 4 is if the force value of pressure sensor is then opened high-speed row and walked electromagnetic valve greater than first threshold.
Above-mentioned intelligent walking motor height double speed control method wherein, after execution of step 4, also comprises step 5, and whether the force value of detected pressures sensor is not more than first threshold, if not, then returns execution in step 1.
Above-mentioned intelligent walking motor height double speed control method, wherein, said first threshold is 20 (Mpa).
The present invention feeds back through pressure in real time, utilizes the controller control electromagnetic valve to carry out the walking of high low speed and switches, and it is unable to solve the walking that high-speed row goes down; Through dual control, set high low speed switching push button, under the state that switches to walking at a high speed, detect running motor pressure and reach more than the 20Mpa, then automatically walking is switched to the low speed walking and use, realize that running motor height double speed switches.
Description of drawings
Through reading the detailed description of non-limiting example being done with reference to following accompanying drawing, it is more obvious that the present invention and characteristic thereof, profile and advantage will become.Mark identical in whole accompanying drawings is indicated identical part.Painstakingly proportionally do not draw accompanying drawing, focus on illustrating purport of the present invention.In the accompanying drawings, for cheer and bright, amplified the part parts, for same parts, only indicated wherein part, those skilled in the art can combine the specific embodiment partly to understand.
Fig. 1 shows according to a present invention specific embodiment, the structural representation of intelligent walking controller for motor; And
Fig. 2 shows according to a present invention specific embodiment, the diagram of circuit of intelligent walking motor control method.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further elaborated.The specific embodiment described herein only is used to explain the present invention, and is not used in qualification protection scope of the present invention.
With reference to the structural representation of intelligent walking controller for motor shown in Figure 1, particularly, intelligent walking controller for motor of the present invention comprises:
High-speed row is walked switch 101, one end ground connection, and the other end connects controller 200; Said controller 200 connects high-speed row and walks electromagnetic valve 301, and said high-speed row is walked electromagnetic valve 301 series connection running motors 401; Measure the pressure sensor (as shown in Figure 1 21,22,23 and 24) of running motor 401, connect said controller 200.
Preferably, the number of said pressure sensor is 4.
More particularly, said 4 pressure sensors (21,22,23 and 24) are measured the oil-feed and the oil outlet of left and right two running motor (not shown in figure 1)s respectively.
