Abstract

The invention relates to a magnetron online fault detection system and a fault detection method, comprising a magnetron working circuit, a collection device connected to the magnetron working circuit, and a display device connected to the collection device; the collection device includes an integrated On the circuit board and independently working to collect filament current, mains current, anode negative high voltage, anode current filament current acquisition module, mains current acquisition module, anode negative high voltage acquisition module, anode current acquisition module and used for analog Single chip microcomputer for digital conversion and data processing; the display device is used to receive the collected physical quantity, analyze the fault cause of the magnetron and display the fault information by judging the threshold range of the physical quantity. The invention can detect multiple physical quantities at the same time, can accurately detect the faults that occur when the magnetron is in use, improves the reliability and completeness of fault detection, and can display fault information intuitively and vividly, improving the work of the staff surroundings.

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...
