Description
Technical field
The present invention relates to a kind of automatic Steering Control System of Tractor Based, belong to course changing control technical field.
Background technique
Automatic steering system as automatic navigation control system important discipline at part, control precision directly affect from
The precision of dynamic electric-hydraulic proportion directional flow control valve navigation system.For current hydraulic steering system poor universality, energy loss
It is larger, fever it is serious the problems such as.The present invention researches and develops a kind of automatic Steering Control System of Tractor Based.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of automatic Steering Control System of Tractor Based.
The present invention is achieved by the following technical solutions: a kind of automatic Steering Control System of Tractor Based, is mainly by touching
Touch screen, controller, D/A converter, ratio valve module, hydraulic oil source, hydraulic steering cylinder, deflecting roller, rotary angle transmitter and AD conversion
Device composition, it is characterised in that: the touch screen is connect with controller, and the input terminal of controller, ratio is arranged in D/A converter
Valve module is connect with hydraulic oil source, and hydraulic steering cylinder and ratio valve module connect, and deflecting roller is connect with hydraulic steering cylinder, and corner passes
Sensor is connect with deflecting roller and converter.
The ratio valve module is by 3 position-5 way electric-hydraulic proportion directional flow control valve, differential pressure type overflow valve and determines subtractive
Pressure valve composition.
The rotary angle transmitter is used to measure or monitor object rotational angle.
The invention has the beneficial effect that automatic Steering Control System of Tractor Based of the invention greatly improves operation essence
Degree, meet operation amplitude is more and more wider, operating speed be getting faster with operation quality increasingly higher demands, and allow driving
Member has the working condition of time enough observation farm implements and the growing state of crops, conducive to the raising of crop.
Detailed description of the invention
Fig. 1 is system schematic of the invention.
In figure, 1, touch screen, 2, controller, 3, D/A converter, 4, ratio valve module, 5, hydraulic oil source, 6, steering hydraulic
Cylinder, 7, deflecting roller, 8, rotary angle transmitter, 9, converter.
Specific embodiment
A kind of automatic Steering Control System of Tractor Based is mainly by touch screen 1, controller 2, D/A converter 3, proportioning valve mould
What block 4, hydraulic oil source 5, hydraulic steering cylinder 6, deflecting roller 7, rotary angle transmitter 8 and converter 9 formed, it is characterised in that: institute
It states touch screen 1 to connect with controller 2, the input terminal of controller 2, ratio valve module 4 and hydraulic oil source 5 is arranged in D/A converter 3
Connection, hydraulic steering cylinder 6 are connect with ratio valve module 4, and deflecting roller 7 is connect with hydraulic steering cylinder 6, rotary angle transmitter 8 and steering
Wheel 7 and converter 9 connect.
The ratio valve module 4 is by 3 position-5 way electric-hydraulic proportion directional flow control valve, differential pressure type overflow valve and fixed poor
Reducer unit at.
The rotary angle transmitter 6 is used to measure or monitor object rotational angle.
The present apparatus carries out automatic steering control system at work, using the tractor steering system of all-hydraulic steering gear
Design has good followability, fast-response and stability.
For the ordinary skill in the art, introduction according to the present invention, do not depart from the principle of the present invention with
In the case where spirit, changes, modifications that embodiment is carried out, replacement and variant still fall within protection scope of the present invention it
It is interior.
