Embodiment 1

[0048] In this embodiment, the coding-based Doppler weather radar fault diagnosis system is a software system loaded on a cloud server and a client, and is hereinafter referred to as a fault diagnosis system. Such as figure 1 As shown, the fault diagnosis system includes a communication module, a fault information collection module, a fault phenomenon description input module, and a fault diagnosis calculation module.

[0049]The user of the fault diagnosis system (hereinafter referred to as the staff) can connect to the cloud server through a mobile terminal (such as a smart phone) or a computer (such as an industrial computer) at the site where the radar is deployed or at a remote location, and call the fault diagnosis system to work. Diagnose radar malfunctions. Mobile terminals are generally used at the scene where the radar is deployed, and computers are generally used at a remote location.

[0050] The communication module is a software function module, which is respec...

Embodiment 2

[0076] In actual work, through the fault phenomenon description input module, the fault phenomenon description input in the form of text, voice or picture may be due to human reasons, and different people have different text and voice descriptions for the same phenomenon; Due to the shooting angle and the size of the lens frame, the images captured for the same phenomenon may not be exactly the same. In this way, when the fault diagnosis calculation module matches the corresponding fault with the basic technology knowledge base according to the fault phenomenon description, there may be options that do not match completely, and a matching error occurs, which in turn causes fault diagnosis errors.

[0077] In order to solve the above technical problems, the following technical solutions are adopted on the basis of embodiment 1:

[0078] When the fault diagnosis calculation module fails to perform accurate matching in the basic technical knowledge base according to the fault phe...

Abstract

The invention provides a coding-based Doppler weather radar fault diagnosis system, and the system comprises: a communication module which is connected with a fault information collection module and a fault phenomenon description input module, and is used for carrying out the communication with a radar and a client; the fault information acquisition module which is used for acquiring fault monitoring information in the radar machine; the fault phenomenon description input module which is used for inputting fault phenomenon description of the radar; and a fault diagnosis calculation module which is respectively connected with the fault information acquisition module and the fault phenomenon description input module, and is used for calculating the fault of the radar according to the fault monitoring information and the fault phenomenon description, and positioning a minimum replaceable unit. The invention also provides a coding-based Doppler weather radar fault diagnosis method. According to the invention, the technical problems that the fault diagnosis of the Doppler weather radar is not fast enough and the minimum replaceable unit cannot be accurately positioned can be solved.

Description

technical field [0001] The invention relates to the technical field of radar fault diagnosis, in particular to a coding-based Doppler weather radar fault diagnosis system and method. Background technique [0002] Various types of faults may occur during the use of Doppler weather radar. Before processing the faults, the fault diagnosis must be carried out first. The minimum replaceable unit can be determined through fault diagnosis, and the fault can be eliminated by repairing or replacing the faulty unit. At present, in order to quickly realize the diagnosis and location of the radar minimum replaceable unit fault, it is necessary to collect complete radar internal fault monitoring information or manual test information, with the help of rich maintenance knowledge and sufficient logical analysis and judgment ability to complete the fault diagnosis. This is also the main reason why experienced engineers must be relied on for Doppler weather radar fault diagnosis and mainten...
