Abstract

The invention relates to a device and a method for remotely solving a fault by utilizing a handheld device. The device comprises a sensor, a PID (proportion-integration-differential) controller and the handheld device, wherein the sensor which can be used for measuring characteristic parameters of an executive component in real time is positioned in engineering machinery and connected with the executive component of the engineering machinery; the PID controller is positioned in the engineering machinery and connected with the executive component; and a wireless data transmitter is fixed in the engineering machinery and connected with a wireless data receiver through a wireless network, and the wireless data receiver is connected with the handheld device. The invention further comprises a method for remotely solving the fault by utilizing the device for remotely solving the fault by utilizing the handheld device. According to the device and the method, the parameters of the remote engineering machinery in a operating process can be collected and transmitted in real time, the fault of the engineering machinery can be quickly determined, the engineering machinery is debugged and controlled by utilizing the remote handheld device, and the maintenance response time of the engineering machinery is shortened.

Description

technical field [0001] The invention relates to a device and a method for remotely solving equipment failures, in particular to a device and a method for remotely solving failures using a handheld device. Background technique [0002] Construction machinery is a relatively complex electromechanical-hydraulic integrated system. Its complex structure and working conditions determine its high frequency and complexity of failures, and the occurrence of a certain failure is usually accompanied by drastic changes in different parameters. These unusually changing parameters would instead indicate the presence of a fault. Therefore, through this causal relationship, the faults that may occur or have occurred in construction machinery can be quickly diagnosed. In the actual process, the basic parameters of construction machinery are usually not collected and fed back in real time, so that the monitoring and analysis of the operation status of construction machinery cannot be accurat...
