Abstract

The invention provides a gas engine rotating speed control method and a circuit used for achieving the method. The gas engine rotating speed control method comprises the following steps that a single-chip microcomputer acquires analog rotating speed signals of a gas engine through an acquisition circuit; the single-chip microcomputer converts the analog rotating speed signals into digital rotatingspeed signals and carries out calculation to obtain pulse width modulation (PWM) signals, and outputs the PWM signals to the input end of a regulation control circuit; and the regulation control circuit controls the rotating speed of the gas engine according to the duty ratio of the PWM signals. According to the gas engine control method and the circuit used for achieving the method, the single-chip microcomputer and the peripheral circuits are used for carrying out control, and great reduction of the cost of a gas engine heat pump system is achieved; and meanwhile, the single-chip microcomputer is superior to a PLC in processing speed, the single-chip microcomputer can also achieve real-time control, universal C language is adopted for programming for the development of the single-chip microcomputer, and the development of the gas engine heat pump system is more flexible and open.

Description

technical field [0001] The invention relates to the technical field of gas engine heat pump systems, in particular to the technical field of gas engine speed control. Background technique [0002] The gas engine heat pump system is a gas engine driven compressor to complete the heat pump cycle to achieve heating or cooling effects. The fuel consumption of the gas engine heat pump is only about 50% of that of the gas boiler, which has good environmental protection and economic value. [0003] The operating speed of the gas engine directly affects the operating effect and efficiency of the gas engine heat pump system. The current speed regulation technical scheme mainly adopts PLC control to collect the speed feedback signal and output the control signal. PLC is not only expensive, but also needs to be used with corresponding signal transmitters; the control system composed of it has poor real-time performance, and the system is relatively closed. The hardware systems of vari...
