Embodiment Construction
[0009] The technical solutions of the present invention will be described in further detail below through specific implementation methods.
[0010] An engine speed regulation method based on the input port, that is, firstly detect whether the engine speed regulation input port is closed and valid; then receive and analyze the input data of the speed regulation input port; Accumulate a step value for the speed data; if it is a deceleration input, then add a step value to the existing external speed data of the engine; finally convert the step value into a rotational speed analog signal after analog-to-digital conversion, It is output to the electronic governor of the engine through the speed regulation drive for speed adjustment.
[0011] Specifically, first detect the state of the speed-regulating input port. After the speed-regulating input port is closed and effective, receive and analyze whether the input data is a speed-up input or a speed-down input. If it is a speed-up i...

The invention provides an engine speed regulation method based on an input port. The engine speed regulation method comprises the steps that firstly, whether the engine speed regulation input port is closed effectively or not is detected; then, an input datum of the speed regulation input port is received and analyzed; if the input datum is speed increasing input, a steeping value is added to an existing external speed datum of an engine; if the input datum is speed decreasing input, a stepping value is subtracted from the existing external speed datum of the engine; and finally, after being converted into a rotating speed analog signal through analog-digital conversion, the stepping value is output to an electronic speed regulator of the engine for rotating speed regulation through a speed regulation driver. The engine speed regulation method based on the input port has the beneficial effects of being scientific in design, great in practicability, simple, reliable, high in stability and precision and the like.
Description
technical field [0001] The invention relates to an engine speed regulation method, in particular to an engine speed regulation method based on an input port.
