Flameout delay and outage control method and system for excavating machine

Abstract

The invention relates to a flameout delay and outage control method and a flameout delay and outage control system for an excavating machine. In order to overcome the defects of complicated structures and fixed delay time of the conventional flameout delay and outage control system for the excavating machine, the flameout delay and outage control system and the flameout delay and outage control method for the excavating machine are provided. The system comprises an electric lock switch, a storage battery, a relay, a controller, a detection device and other electric equipment, wherein the storage battery is connected with a terminal of an electromagnetic coil of the relay through the electric lock switch; the other electric equipment is connected with the storage battery through the relay; and when the electric lock switch is turned off, the controller outputs a high potential to switch on the relay if an engine is positioned in an operating state, and the controller outputs a lower potential to switch off the relay if the engine is positioned in a stalling state. By the control method, whether a power supply is switch off is determined according to the on-off of the engine after the electric lock switch is turned off; and compared with the prior art, the system has the advantages that a delay relay is not provided in structure, so that the system has a simple structure and is low in cost, and an outage occasion is consistent with a stalling occasion of the engine.

Description

technical field [0001] The present invention relates to a control method and system, in particular to a control method and a control system for an excavator flame-out delay power-off. Background technique [0002] At present, excavators use a flameout delay relay to control the power failure of the excavator. In this system, the engine electric lock switch is connected to the battery relay through the delay relay. When the relay still maintains the continuous power supply to the vehicle for a certain period of time, for example, the existing excavator usually uses a flameout delay relay to control the flameout delay for 6 seconds, and the 6 second time is fixed, which causes the entire vehicle to be powered every time the flameout is turned off. The car supplies power for 6 seconds, but in fact, depending on the characteristics of the engine, the use time, the speed of the engine, etc., the time for the engine to change from the running state to the non-running state is betw...
