However, this patent does not have a specific microwave detection device. The usual microwave detection device can only detect the microwave leakage near the antenna, and cannot detect the leakage in the area far away from the antenna. However, the leakage may occur in any position, and this method realizes Can't detect
At the same time, the central processing chip in the patent does not have a specific algorithm for signal processing. The microwave oven theoretically realizes the alarm, but it does not automatically disconnect the power to stop the microwave oven from working. If the alarm is issued, the user will manually disconnect the power supply. , may have caused some property damage

Embodiment Construction
[0034]In order to make the objects, technical solutions and advantages of the present invention, the present invention is further described in detail below in connection with the embodiments.
[0035]The microwave furnace model employed in this embodiment is: M3-232b, the size is 202 (high) × 352 (width) × 325 (depth), and the unit: mm. The microwave oven used in this embodiment has been processed: in order to remove the microwave radiation, the shield layer on the gabric door is cut off, replace it with tin foil paper, and a layer of conductive copper tape is attached to the tin foil paper, ensuring only the required area There is a leak, there is no leakage in other locations.
[0036]Step 1: Take the area of the microwave door area into 3 * 3, such asfigure 2 Indicated;
[0037]Step 2: Symmetrically fixed the half-wave dipolar antenna of 6 central frequencies to the microwave oven door organic glass and radiation protection layer, arrangementimage 3 In the figure, the number of antennas...

The invention provides a device and method for detecting microwave leakage in real time based on an array antenna, belonging to the field of microwave detection. The invention combines the antenna array with a multi-classification model, and can detect the microwave leakage of the equipment in real time and automatically during the use of the microwave equipment. It can not only detect the microwave leakage near the antenna, but also detect Microwave leakage at the antenna position, and use the relevant classification algorithm to judge the leakage location. After confirming the location, use the trained data processing module to calculate the size of the leakage energy. When the leakage energy exceeds the set threshold, the power will be automatically disconnected. Stopping work effectively ensures the safety of the user's personal property, and at the same time displays the location of the leak, which brings great convenience to the later maintenance work.
Description
Technical field[0001]The present invention belongs to the field of microwave detection, and more particularly to devices and methods based on an array antenna real-time detection of microwave leakage.Background technique[0002]The application of microwave energy is extremely wide, almost infiltrated into various fields of social production life. From the application point of view, it is mainly divided into several aspects such as the rapid heating and drying of materials, the sterilization of the food, and materials modification, so various microwave equipment have also become an indispensable part of modern life, for people Life, production and scientific research have brought great convenience. However, if the microwave device occurs in the working process, it will cause great damage to the human body, such as a microwave oven, when the microwave shield is broken, so that the microwave radiation is radiated to the furnace, the human body is strongly microwave radiation, which may r...
