Description
Technical field
The present invention relates to a kind of engine governed speed methods, specifically, relate to a kind of engine tune based on input port
Fast method.
Background technique
The method for controlling speed regulation of general electron speed regulator is increased outside some on the basis of original mechanical speed governors
Portion's device realizes that such method speed regulation accuracy is inadequate, and is easy to appear the unstable of revolving speed, be easy to cause accident, institute
To need one kind that can accurately control revolving speed and speed regulating method easy to operate.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, thus provide a kind of design science, it is practical, simply may be used
It leans on, stability is high, the engine governed speed method with high accuracy based on input port.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of engine governed speed based on input port
Method, that is, first detect whether engine governed speed input port is closed effectively；Then receive and analyze the input of the speed regulation input port
Data；It is inputted if it is raising speed, then the cumulative step value of the existing external speed data of engine；It is defeated if it is reduction of speed
Enter, then existing external one step value of speed data regressive of engine；Finally the step value is turned after analog-to-digital conversion
After being changed to revolving speed analog signal, revolving speed adjustment is carried out by speed regulation driving output to electronic speed-regulator for engine.
Based on voltage value above-mentioned, that the step value is 0-10V by speed regulation driving output.
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, specifically, root of the present invention
According to the speed regulation for entering data to realize electron speed regulator of speed regulation input port, it has function simple, reliable and stable, controls precision
High and easy to maintain feature, can adapt in different speed control occasions, with design science, practical, simple
Single reliable, stability height, advantage with high accuracy.
Detailed description of the invention
Fig. 1 is implementation process block diagram of the invention.
Specific embodiment
Below by specific embodiment, technical scheme of the present invention will be described in further detail.
A kind of engine governed speed method based on input port, that is, first detect whether engine governed speed input port is closed effectively；
Then receive and analyze the input data of the speed regulation input port；It is inputted if it is raising speed, then the existing external speed of engine
Spend one step value of data accumulation；It is inputted if it is reduction of speed, then existing external one stepping of speed data regressive of engine
Value；After the step value is finally converted to revolving speed analog signal after analog-to-digital conversion, by speed regulation driving output to engine
Electron speed regulator carries out revolving speed adjustment.
Specifically, the state of first detection speed regulation input port after the speed regulation input port closure is effective, is received and is analyzed described
Input data is raising speed input or reduction of speed input, is inputted if it is raising speed, then on the basis of engine existing revolving speed, increases
The step value is converted to revolving speed analog signal then by digital-to-analogue conversion by one pre-set step value, by speed regulation
The revolving speed analog signal is converted into the voltage value that electronic speed-regulator for engine can identify after driving output, to change electric current
To carry out raising speed adjusting to engine speed；It is inputted if it is reduction of speed, then on the basis of engine existing revolving speed, reduces one
The step value is converted to revolving speed analog signal then by digital-to-analogue conversion by pre-set step value, is driven by speed regulation
The revolving speed analog signal is converted into the voltage value that electronic speed-regulator for engine can identify after output, to change electric current with right
Engine speed carries out reduction of speed adjusting.
In practice, the voltage value that the step value is 0-10V by speed regulation driving output.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
