Abstract

The invention discloses an intelligent centralized monitoring system for a gas machine, which comprises a 12-bit analog quantity acquisition module (4) used for acquiring data, and a pulse signal pick-up module (5) used for picking up a rotating speed signal. The signal and data acquired by the pulse signal pick-up module (5) and the 12-bit analog quantity acquisition module (4) are input to a 32-bit CPU central processing module (1); and the acquired data is transmitted to a liquid crystal display module (3) through an RS485 signal wire for parameter display of the gas machine. The intelligent centralized monitoring system for the gas machine is provided with a denotation control module (8) used for transmitting a denotation signal to the 32-bit CPU central processing module (1) and an ignition control module (7) so as to protect an engine against denotation. The intelligent centralized monitoring system for the gas machine has a plurality of centralized parameter acquisition points,and can intelligently analyze the operation condition of the current gas machine according to various preset curves and graphs, output an analysis result and perform timely and effective control on the machine when the gas machine has the denotation.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitoring and discloses an intelligent centralized monitoring system for gas machines. Background technique [0002] The control system of the existing gas engine is mainly based on a mechanical or 8-bit CPU distributed electronic monitoring system. The system is composed of a machine side control box and a remote control console. The machine side control box collects engine oil temperature, water temperature, oil pressure, and rotational speed. , to start and stop the engine. The remote control console collects the engine cylinder temperature, water temperature, and speed, and controls the gas and air volume. The parameter collection and control of the whole system are relatively scattered, with few collection points, no centralized intelligent control function, no automatic analysis function of gas engine operating parameters, no knock control function and ignition control function of gas ...
