Detailed description of the invention

Below according to the drawings and specific embodiments, the utility model is described in further detail:

As in figure 2 it is shown, a kind of craft tug learning machine of the present utility model, including single-chip microcomputer, PLC, an operation handle depends on Secondary pass through the first handover module, the first analog-digital converter is connected with single-chip microcomputer, and single-chip microcomputer pass sequentially through digital to analog converter, first Amplifier, the second handover module are connected with ratio controlling organization；Operation handle is also by the first handover module with described PLC even Connecing, PLC passes sequentially through the second amplifier, the second handover module is connected with described ratio controlling organization；Ratio controlling organization is successively It is connected with single-chip microcomputer by feedback box, the second analog-digital converter, and feedback box is also connected to described PLC；Operation handle inner sets There is handle angle sensor, in feedback box, be provided with feedback box angular transducer.PLC input ac power, single-chip microcomputer input direct-current Power supply.

Wherein ratio controlling organization mainly includes hydraulic system, the second handover module and the proportional control valve in hydraulic system Connect, the signal intensity that exports with single-chip microcomputer or PLC and the uninterrupted that changes hydraulic oil and flow direction make whirler according to Command request works.

As it is shown in figure 1, be the principle schematic of hydraulic system, wherein 1 is liquidometer, and 2 is thermometer, and 3 is filter, 4 For hydraulic oil pump, 5 is motor, and 6 is electromagnetic valve, and 7 is needle-valve, and 8 is Pressure gauge, and 9 is proportional control valve, and 10,12 is flexible pipe, and 11 are Oil motor, 13 is overflow valve, and 14 is storm valve.

This utility model, before formally coming into operation, should adjust handle angle sensor and feedback box angular transducer, make Handle indicated angle degree consistent with feedback box pointer angle time rudder oar (whirler) stop operating.

Wherein operation handle is combined type handle, drives angular transducer (potentiometer) to rotate by horizontal 360-degree, its conduct Instruction module output analog quantity command signal；First handover module is to cut between selection control, i.e. ' single-chip microcomputer ' or ' PLC ' Change；First analog-digital converter, when " single-chip microcomputer " works, is changed into digital signal command signal and is input to single-chip microcomputer, defeated Go out signal and be changed into analogue signal to ratio controlling organization；First, second amplifier can be put the working signal of controller output Greatly so that it is ratio controlling organization can be promoted to work；Single row machine and PLC accept command signal and feedback signal and to the two signal Compare, send work order according to operation result；Angular transducer in feedback box, follows whirler and rotates together, real Time rotary angle signal is fed back to single-chip microcomputer and PLC.

Operation principle of the present utility model

Follow-up steering: the full closed loop control loop being made up of electric, hydraulic mechanism realizes, and operator drives platform by rotation On operation handle make the synchronous axial system that rudder oar (whirler) follows, controller detect the angular transducer on handle in real time With the differential seat angle of the angular transducer in rudder oar (whirler) feedback box, send control signal to proportional control valve, finally allow rudder Oar (whirler) is consistent with handle angle.Controller has PLC or single-chip microcomputer as controlling CPU.

When selecting follow-up steering, the most first " handover module " switch is placed in " single-chip microcomputer " or " PLC ", both effects Identical, backup each other.The factor impacts such as the operation in view of rudder oar (whirler) rotation system inertia and driver, the mistake of steering Difference sensitivity (also known as " dead band ") is general≤± 3 °, the input and output of single-chip microcomputer need to be believed when being controller when selecting " single-chip microcomputer " Number carrying out analog digital conversion becomes digital quantity signal analog signals, and output signal carries out digital-to-analogue conversion and digital quantity signal is become Analog signals.When selecting " PLC " as controller, because " PLC " is per se with analog input and output module, so not Need conversion.

When follow-up steering requires more than 180 °, operator implements in two steps.First step steering does not exceeds 180 °, works as rudder Oar (whirler) grasps second time again to predetermined angular after turning over certain angle.If once rotating more than 180 °, then rudder oar (rotates Machine) predetermined angular can be arrived by shortest path opposite direction.

But, above-mentioned detailed description of the invention is exemplary, is to preferably enable those skilled in the art Understand this patent, it is impossible to be not understood as this patent is included the restriction of scope；As long as the institute according to spirit disclosed in this patent Any equivalent change made or modification, each fall within the scope that this patent includes.
