Embodiment Construction

[0013] The specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0014] The digital electronic governor of the present invention is a precision control device that stably controls the engine to run at a set working speed. According to the different implementation modes, it can be divided into mechanical governors, hydraulic governors, electro-hydraulic governors, In terms of control principles, electronic speed governors and compound governors, etc., various speed governors have mechanisms for speed setting, speed measurement, comparison, calculation, drive output, actuators, adjustment coefficient setting, protection or restriction, etc. Or components, each mechanism or component is effectively combined to form a closed-loop control system.

[0015] The digital electronic speed governor of the present invention is composed of a speed controller, an actuator, a speed sensor, and cables connecting the above-mentioned compon...

Abstract

The invention relates to a digitalized electronic speed regulator. The digitalized electronic speed regulator comprises a rotating speed controller, a rotating speed sensor, an actuator and cables, wherein the rotating speed controller sets the desired rotating speed, the rotating speed sensor collects the practical rotating speed, the actuator regulates the practical rotating speed, and the cables are connected with the rotating speed controller, the rotating speed sensor and the actuator. The rotating speed controller further comprises a rotating speed setting potentiometer, a comparator, a rotating speed deviation device, a converter and a PID regulator, wherein the rotating speed setting potentiometer sets the desired rotating speed, the comparator compares the desired rotating speed with the practical rotating speed, the rotating speed deviation device calculates rotating speed deviation value of the desired rotating speed and the practical rotating speed, the converter converts the practical rotating speed into a digital square wave, and the PID regulator converts the rotating speed deviation value into PWM. The invention further provides an engine speed regulation method. The digitalized electronic speed regulator and the engine speed regulation method have the advantages that a power system is safer in operation and running, the dispersion performance is better, and the stability is better.

Description

Technical field [0001] The invention relates to a motor equipment system, in particular to a digital electronic speed governor for diesel engines and a speed control method. Background technique [0002] The work of diesel engines needs to be stabilized by a speed adjustment device called a governor. The fuel supply of the commonly used diesel engine is determined by the position of the plunger of the fuel injection pump, and the position of the plunger of the fuel injection pump is determined by the fuel injection pump. The plunger position controls the rack to adjust, the governor uses the association between the tachometer and the plunger position control rack, and uses the "negative feedback" mode to stabilize the speed of the diesel engine and prevent runaway. The principle of the mechanical governor , The speed is adjusted by the balance of the centrifugal force and spring force generated when the fly block rotates; when the spring force is constant, the high speed will gen...
