Description
[technical field]
The utility model relates to the composition system of a kind of hydraulic pressure autonomous traveling vehicle, is specifically related to the controlled Micro-positioning of a kind of hydraulic pressure autonomous traveling vehicle system, belongs to the special vehicle technical field.
[background technology]
At present, many construction projects need to be transported large component and be closed up assembling, therefore, need transport vehicle accurately to locate when the close parent of transport section or base.Traditional open loop control need to need repeatedly be adjusted just and can put in place simultaneously by workmen's range estimation, and operating efficiency is low, danger is large.
Therefore, for solving the problems of the technologies described above, necessary the controlled Micro-positioning of a kind of novel hydraulic pressure autonomous traveling vehicle system that provides is to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of registration, operating efficiency is high and use the controlled Micro-positioning of the hydraulic pressure autonomous traveling vehicle system of safety.
For achieving the above object, the technical scheme that the utility model is taked is: the controlled Micro-positioning of a kind of hydraulic pressure autonomous traveling vehicle system, and it comprises driving engine, tachogen, remote controller, ECU ECU (Electrical Control Unit), PLC controller, drives controllable capacity pump and brake pump; Wherein, described remote controller, tachogen connect respectively and carry signal to the PLC controller; Described PLC controller connect respectively and transmission of signal to the ECU ECU (Electrical Control Unit), drive on controllable capacity pump and the brake pump; Described ECU ECU (Electrical Control Unit), driving controllable capacity pump and brake pump are connected on the driving engine respectively.
The controlled Micro-positioning of hydraulic pressure autonomous traveling vehicle of the present utility model system further is set to: described driving controllable capacity pump is connected with some variable-dis-placement motors.
The controlled Micro-positioning of hydraulic pressure autonomous traveling vehicle of the present utility model system further is set to: be connected with a brake activation valve and some brake cylinders on the described brake pump.
The controlled Micro-positioning of hydraulic pressure autonomous traveling vehicle of the present utility model system also can be set to: described tachogen is installed on the tire.
Compared with prior art, the utlity model has following beneficial effect: the Vehicle Driving Cycle distance of the controlled Micro-positioning of hydraulic pressure autonomous traveling vehicle of the present utility model system can be set by remote controller, pass through the variable of PLC controller control engine rotating speed and pump when travelling, to realize that vehicle travels with minimum steady speed, simultaneously by being installed in the tachogen feedback vehicle speed signal on the tire, when near the target location, control simultaneously brake activation valve by the variable that reduces engine speed and pump and progressively increase braking force, make vehicle accurately stop at the target location, and working security is large, and efficient is high.
[description of drawings].
Fig. 1 is the schematic diagram of the controlled Micro-positioning of hydraulic pressure autonomous traveling vehicle of the present utility model system.
[specific embodiment]
See also shown in the Figure of description 1, the utility model is the controlled Micro-positioning of a kind of hydraulic pressure autonomous traveling vehicle system, its by driving engine 1, tachogen 2, remote controller 3, ECU ECU (Electrical Control Unit) 4, PLC controller 5, drive several parts such as controllable capacity pump 6 and brake pump 7 and form.
Wherein, described remote controller 3, tachogen 2 connect respectively and carry signal to PLC controller 5.Described PLC controller 5 connect respectively and transmission of signal to ECU ECU (Electrical Control Unit) 4, drive on controllable capacity pump 6 and the brake pump 7.Described ECU ECU (Electrical Control Unit) 4, driving controllable capacity pump 6 and brake pump 7 are connected to respectively on the driving engine 1.
Further, described driving controllable capacity pump 6 is connected with some variable-dis-placement motors 61.Be connected with a brake activation valve 71 and some brake cylinders 72 on the described brake pump 7.Described tachogen 2 is installed on the tire 8.
The principle of work of the controlled Micro-positioning of hydraulic pressure autonomous traveling vehicle of the present utility model system is as follows: set operating ranges by remote controller 3, distance parameter and the order of travelling are sent to PLC controller 5, PLC controller 5 carries out operational analysis by predefined program, order is decomposed ECU ECU (Electrical Control Unit) 4 and drives controllable capacity pump 6, coordinate the displacement size of rotating speed and the driving controllable capacity pump 6 of control engine 1.At this moment, vehicle begins to travel with minimum steady speed, distance according to operating range, can automatically carry out the speed of a motor vehicle regulates, in this process, the tach signal that is arranged separately in the tachogen 2 Real-Time Monitoring tires 2 on the wheel 8 sends to PLC controller 5, but moving velocity and operating range by PLC controller 5 analytic operation Real Time Monitoring vehicles, when operating range during near expected value, PLC controller 5 transmits control signal to ECU ECU (Electrical Control Unit) 4 and drives controllable capacity pump 6, be reduced to gradually idling by Engine ECU ECU (Electrical Control Unit) 4 control engines 1 rotating speed, the discharge capacity that drives controllable capacity pump 6 by driving variable-dis-placement motor 61 controls is reduced to zero delivery gradually, and this moment, power cut off, but vehicle still continues to travel with inertia, brake pump 7 begins braking when approaching expected value, until vehicle stops according to the position of appointment.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
