Description
Technical field
The utility model relates to rice transplanter technical field, particularly relates to a kind of rice transplanter drive-control system.
Background technology
At present, riding-type rice planter travel speed and direction are generally regulated by following mechanism:
1, throttle control handle (or gas pedal) is for regulating engine speed;
2, main gear change hand lever is for regulating HST hydraulic motor displacement;
3, gear selects handle for regulating forward-reverse gear and high low gear;
By the joint operation of above mechanism, human pilot can realize rice transplanter and fall back and high low speed driving in the advance in field.But regulate rice transplanter travel speed and direction to need pilot oil door handle (or pedal), main gear change hand lever and gear to select handle, human pilot also needs steering dish and other equipments, handles comparatively loaded down with trivial details simultaneously.Need to regulate main gear change hand lever and throttle control handle owing to changing travel speed, for convenience of operation, driver generally can fix larger throttle, and the main gear change hand lever of single pass-through regulates travel speed, because this increasing oil consumption during low speed driving.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of and can save oil consumption, have rice transplanter drive-control system simple to operation simultaneously.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
A kind of rice transplanter drive-control system, comprising: for regulating the gear shift pedal of rice transplanter speed and having the controller of pid control function; It is characterized in that: also comprise actuating motor, speed change link gear and gear position sensor; Wherein: described gear shift pedal comprises gas pedal and the angular transducer for detecting accelerator pedal position; The signal output terminal of described angular transducer is electrically connected with the I/O terminal of controller; The I/O terminal of described controller is electrically connected with the control signal terminal of actuating motor by data line; Described speed change link gear comprise the fluted disc engaged with actuating motor, the axle welded with the fluted disc central vertical of described fluted disc, be enclosed within described axle extenal fixation link gear axle sleeve, with the support of described axle vertical welding; Gear position sensor for detecting described fluted disc position is fixedly installed in described support; The signal output terminal of described gear position sensor is electrically connected with the I/O terminal of controller.
Further: between described angular transducer and the I/O terminal of controller, to be also provided with analog to digital converter.
Also analog to digital converter is provided with between described gear position sensor and the I/O terminal of controller.
The advantage that the utility model has and good effect are: the utility model is by gathering the positional information of gas pedal and then driving link gear, regulate engine throttle and motor displacement by PID control principle simultaneously, power joint needed for cooperation regulates throttle, thus saves fuel oil.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Wherein: 10, controller; 11, gear shift pedal; 12, actuating motor; 13, speed change link gear; 14, gear position sensor.
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1: a kind of rice transplanter drive-control system.Comprise: controller 10, gear shift pedal 11, actuating motor 12, speed change link gear 13 and gear position sensor 14; Wherein: gear shift pedal 11 is for regulating the speed of rice transplanter, and as preferred embodiment, gear shift pedal 11 herein comprises gas pedal and the angular transducer for detecting accelerator pedal position; Controller 10 is for having the controller of pid control function; Namely pid control function wherein can be realized by PID control chip, also can be realized by pid algorithm software; Controller 10 herein also has other some functions of controller on traditional rice transplanter, such as monitors and shows the duty of rice transplanter; The signal output terminal of described angular transducer is electrically connected with the I/O terminal of controller 10; The I/O terminal of described controller 10 is electrically connected with the control signal terminal of actuating motor 12 by data line; Described speed change link gear 13 comprise the fluted disc engaged with actuating motor 12, the axle welded with the fluted disc central vertical of described fluted disc, be enclosed within described axle extenal fixation link gear axle sleeve, with the support of described axle vertical welding; When actuating motor 12 rotates, the torsion that motor exports is passed to axle by fluted disc by speed change link gear 13, then is passed to fork from axle, and fork drives the engine throttle bracing wire of rice transplanter and main speed-changing pull rod to stretch simultaneously, thus realizes speed change; Gear position sensor 14 is for detecting the gear position of described fluted disc position, and gear position sensor 14 is fixedly installed on described support; The signal output terminal of gear position sensor 14 is electrically connected with the I/O terminal of controller 10.Controller 10 reads the positional information of current gear shift pedal 11, as the setting value of travel speed, it is minimum setting value under gas pedal state of nature, as halted state, gas pedal step on to during extreme position as the state that travel speed is maximum, the angle linear increment that the setting value of speed is stepped on along with pedal.After controller 10 reads the positional information of gear shift pedal 11, then read the positional information of fluted disc position transducer 14, i.e. the values for actual speed of current driving, and speed setting value and values for actual speed are compared.When setting speed and actual speed exist deviation, controller 10 controls actuating motor 12 and drives speed change link gear 13 to regulate the speed of a motor vehicle, until actual speed is consistent with setting speed; Above-mentioned control procedure is completed by PID control chip or pid algorithm software, because PID control chip or pid algorithm software are the technology of existing comparative maturity, therefore repeats no more herein.
Simultaneously in order to ensure the stability of signal: be also provided with analog to digital converter between described angular transducer and the I/O terminal of controller 10.
In like manner, between described gear position sensor 14 and the I/O terminal of controller 10, also analog to digital converter is provided with.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
