Embodiment 1

[0019] An embodiment of the present invention provides a method for troubleshooting a construction machine. Such as figure 1 As shown, the method includes:

[0020] Step S10 , collecting operating parameters of the construction machine when it is working.

[0021] Specifically, in this solution, the collected operating parameters of each system equipment of the engineering machinery during operation can be transmitted through sensors or CAN bus. Optionally, the above-mentioned engineering machinery can be one or more of the chassis of the crane vehicle. system equipment. It should be noted here that the operating parameters of multiple system devices in the crane can be collected.

[0022] Step S12, judging whether the engineering machinery fails according to the collected operating parameters.

[0023] Optionally, in this solution, the collected motion parameters of the vehicle can be sent to the main controller through the sensor and the CAN bus, and the main controller ...

Embodiment 2

[0107] This embodiment also provides a system for troubleshooting engineering machinery, such as Figure 4 As shown, the system can include:

[0108] The main controller 10 is used to collect operating parameters of the construction machinery and judge whether the construction machinery fails according to the collected operation parameters; in the case of a fault in the construction machinery, generate fault information according to the operation parameters, wherein the fault information includes The name of the system equipment where the failure occurred in the construction machinery.

[0109] Specifically, in this solution, the collected operating parameters of each system equipment of the engineering machinery during operation can be transmitted through sensors or CAN bus. Optionally, the above-mentioned engineering machinery can be one or more of the chassis of the crane vehicle. system equipment. It should be noted here that the operating parameters of multiple system d...

Abstract

The invention discloses a fault handling method and system for engineering machinery. The method comprises the following steps: collecting operational parameters while the engineering machinery is working; judging whether the engineering machinery is in fault based on the collected operational parameters; generating fault information based on the operational parameters in condition of the engineering machinery is in fault, wherein the fault information comprises name of the system equipment which is in fault in the engineering machinery; and calculating for generating fault level information based on the fault information. The fault handling method and system for engineering machinery solves the problem that efficiency is low in the prior art, because the driver has to judge faults of all equipment.

Description

technical field [0001] The present invention relates to the field of mechanical control, in particular to a method and system for troubleshooting engineering machinery. Background technique [0002] As the complexity of construction machinery continues to increase, the failures of construction machinery during work have also increased a lot. For example, the electrical system of a crane, the failure of the electrical system will cause the failure of the vehicle to varying degrees, and the failure of the vehicle mainly uses electrical components such as indicator lights and buzzers to remind the driver to overhaul the vehicle and eliminate the failure. Some vehicle faults will affect the safety of the vehicle, and some can be ignored without affecting the performance of the vehicle at all. The faults that affect safety must be dealt with immediately, and the faults that can be ignored can be dealt with when the car is not working. [0003] What needs to be explained here is ...
