Abstract

The invention relates to an online fault detecting system and method for a magnetron. The online fault detecting system comprises a magnetron operating circuit, a collecting device and a display device, wherein the collecting device is connected with the magnetron operating circuit, and the display device is connected with the collecting device. The collecting device comprises a filament current collecting module, a mains supply current collecting module, an anode negative high voltage collecting module, an anode current collecting module and a single-chip microcomputer, wherein the filament current collecting module, the mains supply current collecting module, the anode negative high voltage collecting module and the anode current collecting module are arranged on one circuit board in an integrated mode and independently operate to collect filament current, mains supply current, anode negative high voltage and anode current respectively, and the single-chip microcomputer is used for analog-digital conversion and data processing. The display device is used for receiving collected physical quantities and analyzing the fault reason of the magnetron by judging the threshold ranges of the physical quantities and is also used for displaying fault information. By the adoption of the online fault detecting system and method for the magnetron, multiple physical quantities can be detected at the same time, faults caused during use of the magnetron can be accurately detected, the reliability and the completeness of fault detection are improved, fault information can be visually displayed, and the working environment of workers is improved.

Description

technical field [0001] The invention relates to a magnetron working state detection system, more specifically, an online fault detection system and a fault detection method for a magnetron. Background technique [0002] Magnetrons have been widely used in many fields. The tunnel heating method of high-power magnetrons composed of small power parallel connections is very common. When magnetrons continue to operate for a long time in this high-temperature and high-pressure environment, it is easy to cause Failures due to environmental factors or equipment aging will have a great impact on production safety and production efficiency if the cause of the failure cannot be diagnosed in a timely and accurate manner to take rash measures. [0003] During the working process of the magnetron, some physical quantities that are valuable for monitoring the working state of the magnetron are often not favored by users because they are inconvenient to measure or require professional equip...
