Background technology
Industrial revolution period, the appearance of steam engine, accelerate the progress of mankind's science and technology civilization.Outside so-called steam engine is belonging to
Combustion engine, is wherein through external firing, the water of boiler internal is heated generation high-temperature high-pressure steam indirectly, then is transported to machine
Go work done, be a kind of the heat energy device that is converted into mechanical energy.But, for external-combustion engine, the invention of internal combustion engine is especially
It is widely used in the modern times, seems the electromotor of automobile, boats and ships, aircraft, agricultural machinery, rocket etc. or engine is substantially all in being belonging to
Combustion engine.So-called internal combustion engine needs by means of fuel combustion, according to the difference of operation principle can be general be divided into reciprocating-piston in
Combustion engine, rotary engine, gas-turbine unit, jet engine etc..But, the fuel that internal combustion engine uses, typically all carbon
Hydrogen compound, common are gasoline, diesel oil, natural gas, kerosene etc., and these is also called fossil energy, are also that the current mankind make
Main energy sources in particular, this energy just utilizes along with continuous exploitation and gradually decreases, further, because energy
The problem in source has even caused war.It addition, the problem using fossil energy maximum is the pollution of ecological environment, its Minerals energy
Source produces the toxic and harmfuls such as substantial amounts of CO2, SO2, HC, O3 in combustion, and these not only cause the pollution of environment also
Causing many diseases such as human respiratory obstacle and cancer, fossil fuel also result in acid rain simultaneously increases, the life to the mankind
Dis environment creates huge negative effect.
It addition, indispensable one big it is important that grain of human survival, from ancient times to the present, there is grain and ask always
Topic, therefore people the most constantly improve the development of agricultural, are even used for agriculturally, from hand-held tool to large-scale agriculture by the development of science and technology
Machine is constantly improved, and wherein most agricultural machinery is in order to automatization and laborsaving most meeting allocation engine are to reach laborsaving and automatization
Purpose.It is noted that described agricultural machinery refers to the various plant equipment used in agricultural production, say further also
That is mechanization of agriculture is the condition improving agricultural production through advanced and applicable agricultural machinery, even some farm machinery it is
Utilize certain activity imitating the mankind, go replace people's onerous toil or utilize in the environment of the unaccommodated work of people
Farm machinery is operated, to improve production technology level and the economic benefit of agricultural.But, farm machinery now is most
Being all to use internal-combustion engine system, the most common is exactly electromotor or engine.
Therefore, in the various utilizations of agricultural engine, although bring agricultural development quick, but also bring environment simultaneously
Pollution.First, the harmful gas that the non-complete combustion of fuel of internal combustion engine produces directly is discharged can be to environment, this
Increase the weight of haze weather undoubtedly.It addition, the main emission of internal combustion engine is CO2, steam and some particulate matters.Further,
Internal combustion engine also can discharge carbon monoxide, nitrogen oxides, sulfide (mainly sulfur dioxide) and some unburned nytrons
Thing.The health of the mankind is adversely affected by these waste gas.Next, the incomplete combustion of the fuel such as the diesel oil of internal combustion engine, gasoline
Burn the waste not only easily causing the energy.It addition, the weight of the internal combustion engine of existing agricultural machinery is relatively big, cause the agricultural machinery can not be by agriculture
Operators operates neatly.
Therefore, along with the use of electric bicycle, electric automobile etc., people gradually see using electric power as power source
Machinery is for health and the Beneficial Effect of natural environment.Therefore, electric power is applied in agriculture as power source replacing fuel oil
Industry mechanically becomes a trend, but among the agricultural machinery power driven system using electric power as power source, it is worth mentioning at this point that
Body manipulation unit, say, that operator goes to control agricultural machinery through described manipulation unit, and in other words, described manipulation unit is
Critically important human-computer interaction system.
