Automatic fault protection method and system for bulldozer

Abstract

The invention discloses an automatic fault protection method for a bulldozer, which comprises the followings: acquiring operational parameters of the bulldozer in real time; making a comparison between the operational parameters and a pre-set value, judging whether the operational parameters meet the pre-set value or not, if not, making a comparison between the operational parameters and date stored in a fault database, and determining corresponding fault grades and fault codes; generating corresponding control signals to control an engine according to fault grades. The invention further discloses an automatic fault protection system for the bulldozer. According to the invention, in the case of faults on the bulldozer, the fault grades can be determined according to the data stored in the fault database, and corresponding control to the engine can be performed according to corresponding fault grades. Therefore, automatic protection to the bulldozer can be achieved.

Description

technical field [0001] The invention relates to the technical field of bulldozer fault protection, and more specifically, to a bulldozer automatic fault protection method and system. Background technique [0002] At present, bulldozers are earth-rock scraping machines commonly used in engineering. The whole machine includes multiple systems such as machinery, hydraulic pressure, and electrical appliances. The working environment is relatively harsh, and failures are inevitable during the production process. [0003] Due to the wide application of CAN bus technology and sensor technology in the field of construction machinery, more and more bulldozer products have fault diagnosis functions. Through a large number of sensors to collect data from the measurement points, the controller will make a real-time logical judgment on the data transmitted by all the sensors. If the judgment result is some kind of fault, it will display the corresponding fault code and a simple prompt on...

However, this phenomenon often exists in reality. When a certain fault occurs in the bulldozer, if the operator, especially the inexperienced operator, does not have a clear understanding of the meaning of the fault and its harm to the machine, the operator may have It is possible to ignore the fault alarm prompt and continue to use the machine. At this time, it may cause greater harm to the machine or even the operator himself.
