Embodiment 1

[0040] A fault diagnosis method provided by the embodiment of the present invention can be applied to on-site maintenance of ground meteorological observation and detection equipment, such as figure 1 As shown, the fault diagnosis methods include:

[0041] S11: Receive the fault data collected and sent by the test terminal.

[0042] S12: Generate a diagnosis task according to the fault data.

[0043] As a preferred implementation of this embodiment, a diagnostic task for troubleshooting is generated according to the received fault data.

[0044] S13: Search the fault diagnosis database according to the diagnosis task, and obtain the diagnosis process;

[0045] In this step, search the fault diagnosis database according to the troubleshooting task to obtain the guiding steps of the diagnosis process.

[0046] S14: Send information about the diagnosis process to the test terminal.

[0047] Specifically, the fault diagnosis method provided by this embodiment can be carried ou...

Embodiment 2

[0051] A fault diagnosis method provided by the embodiment of the present invention can be applied to on-site maintenance of ground meteorological observation and detection equipment, such as figure 2 As shown, the fault diagnosis methods include:

[0052] S21: Receive the fault data collected and sent by the test terminal.

[0053] S22: Receive a fault report signal sent by the test terminal.

[0054] S23: Generate a diagnosis task according to the fault data.

[0055] As another implementation manner of this embodiment, a diagnostic task for troubleshooting is generated according to the received fault data.

[0056] S24: Record, edit and store fault data and diagnostic tasks.

[0057] As an optimal solution, it is also possible to make statistics on information such as fault data and diagnostic tasks, so as to facilitate retrieval of diagnostic task records.

[0058] S25: According to at least one of the model of the faulty device, the fault phenomenon, the type of the ...

Embodiment 3

[0077] A fault diagnosis system provided by an embodiment of the present invention, such as Figure 4 As shown, the fault diagnosis system 3 includes a memory 31 and a processor 32. The memory 31 stores a computer program that can run on the processor 32. When the processor 32 executes the computer program, the method provided by the first or second embodiment above is implemented. A step of.

[0078] Such as Figure 4 As shown, the fault diagnosis system 3 also includes: a bus 33 and a communication interface 34 . The processor 32 , the communication interface 34 and the memory 31 are connected through a bus 33 ; the processor 32 is used to execute executable modules stored in the memory 31 , such as computer programs.

[0079] Wherein, the memory 31 may include a high-speed random access memory (RAM, Random Access Memory), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. The communication connection between the system net...

Abstract

The invention provides a fault diagnosis method and system, and relates to the technical field of equipment maintenance. The fault diagnosis method comprises the steps of receiving fault data which is collected and transmitted by a test terminal; generating a diagnosis task according to the fault data; searching a fault diagnosis database according to the diagnosis task to obtain a diagnosis process; and transmitting information of the diagnosis process to the test terminal. The fault diagnosis method and system solve a technical problem that the efficiency of fault maintenance is reduced because it is difficult to perform a correct fault diagnosis operation on complex and large-scale equipment through manual judgment in the prior art.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance, in particular to a fault diagnosis method and system. Background technique [0002] Fault detection is the process of using various inspection and testing methods to find out whether there is a fault in the system and equipment, and fault location is the process of further determining the location of the fault. Fault isolation is the process that requires localization of faults to the level of the product that can be replaced when repairs are performed. Fault diagnosis is the process of combining fault detection and fault isolation. [0003] Fault diagnosis is the process of finding faults in equipment or systems. The program used to check and find faults is called a diagnostic program, and the system that performs diagnosis on other devices or systems is called a diagnostic system. System fault diagnosis is to make judgments on the system operating status and abnormal conditions,...
