Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, this embodiment provides a digital electronic speed governor, including a speed controller 11 for setting the ideal speed, a speed sensor 12 for collecting the actual speed, and an actuator for adjusting the actual speed. The controller 11 includes a rotational speed setting potentiometer 111 for setting the ideal rotational speed, an F / V converter 114 for converting the analog signal of the actual rotational speed sensor 12 into a digital signal for the rotational speed controller 11, and an F / V converter 114 for comparing the ideal rotational speed A comparator 112 with the actual speed, a speed deviation device 113 for calculating the speed deviation between the ideal speed and the actual speed, and a PID regulator 115 for converting the speed deviation into a PWM signal to control the actuator. Under the...

Abstract

The invention provides a digital electric speed regulator and an engine speed regulating method. The digital electric speed regulator comprises a rotating speed controller, an actuator and a rotating speed sensor, wherein the rotating speed controller comprises a rotating speed setting potentiometer which is used for setting a desired speed, an F/V converter which is used for converting analog signals of the actual rotating speed sensor into digital signals and sending the digital signals to the rotating speed controller, a comparator which is used for comparing a desired speed with an actual rotating speed, a rotating speed deviation device which is used for calculating the rotating speed deviation value between the desired speed and the actual rotating speed, and a PID regulator which is used for converting the rotating speed deviation value into a PWM signal to control the actuator, the actuator compresses an internal spring under the action of driving currents to achieve linear motion output, and a pull rod of the actuator acts on a speed regulating handle of an engine to control the engine to operate stably at the set rotating speed. The digital electric speed regulator and the engine speed regulating method have the advantages that a power system can be operated and run more safely, the discreteness is good, and stability is good.

Description

technical field [0001] The invention relates to a digital electronic governor and an engine speed regulating method. Background technique [0002] The operation of the diesel engine needs to be stabilized by a speed adjustment device, called a governor. The fuel supply amount of the diesel engine commonly used at present 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 plunger position controls the rack to adjust. The governor uses the "negative feedback" mode to stabilize the speed of the diesel engine and prevent the speed of the engine. The principle of the mechanical governor The speed is adjusted by the balance of the centrifugal force and the spring force generated when the flying block rotates; when the spring force is constant, the centrifugal force generated when the speed is high and the rapid rotation is high, and the position of the plunger is pushed to ...
