Description
Technical field
The invention belongs to agricultural machinery control technology field, in particular, combine feedback loading control system.
Background technology
Combine, as modern agriculture harvest machinery, has been widely used in agricultural production.Its application improves agricultural production efficiency, alleviates the labour intensity of peasant.In recent years, in China's agricultural production, the harvesting proportion using combine to carry out crops strengthens year by year.But the grain header of current domestic production is Purely mechanical substantially, and workmanship is comparatively coarse, causes harvesting efficiency not to be very stable always, also often cause fault, the inducement of these faults is cause because grain header load is excessive mostly.But in actual mechanical process, operating personnel but often cannot make accurate judgement to the size of grain header load, can only by virtue of experience operate, cannot accurate control overhead amount.Therefore the artificial loss ratio of grain header is larger.In addition, the domestic grain header of major part also exists the defect that intelligent digital degree is not high, control difficulty, causes operating personnel cannot control the load of grain header in time and accurately.In this case, grain header often breaks down due to the work of long-time high load capacity, and a lot of fault causes the damage of grain header parts, causes grain header normally to work, affects agricultural production efficiency, and improves the kind ground cost of peasant.
Compared with domestic, generally use the grain header that intelligence degree is very high abroad, grain header failure rate is low, agricultural production efficiency is high, and Competition Ability of Agricultural Products is obvious.
Summary of the invention
The present invention, in order to effectively solve above technical problem, gives a kind of combine feedback loading control system.
A kind of combine feedback loading control system of the present invention, is characterized in that: ARM controller, Ethernet card, signal conversion module A, signal conversion module C, I/O port, signal conversion module D, signal conversion module B, serial communication interface, host computer, LCD touch screen, power module, sounding and lighting alarm module, system reset module, speed probe, entrainment loss sensor, granary flow sensor, cleaning loss sensor, driver module, stepper motor; Wherein:
Described ARM controller respectively with described Ethernet card, described signal conversion module A, described signal conversion module C, described I/O port, described signal conversion module D, described signal conversion module B, described serial communication interface is connected, described host computer respectively with described Ethernet card, described serial communication interface, described LCD touch screen, described power module, described sounding and lighting alarm module, described system reset module is connected, described signal conversion module A is connected with described speed probe, described signal conversion module C is connected with described entrainment loss sensor, described signal conversion module B is connected with described cleaning loss sensor, described signal conversion module D is connected with described granary flow sensor, described I/O port is connected with described driver module, described driver module is connected with described stepper motor.
The combine feedback loading control system that the present invention provides, automatically can adjust duty according to payload, fill the domestic gaps, and just seems extremely urgent with the demand adapting to China's agricultural development.So just can reduce the gap of China and developed country, promote China harvest machinery industry capability of independent innovation, improve industry total quality, improve farmers' income, promote agricultural restructuring, and provide technical equipment to support for agricultural modernization.The present invention is compared with prior art: have that system architecture is simple, installation and debugging convenient, system reliability is high, certainty of measurement is high, low in energy consumption, be easy to penetration and promotion, the advantage such as easy to maintenance.
