Problems solved by technology

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 centra

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.

[0035] The model of the microwave oven adopted in this embodiment is: M3-232B, the size is 202 (height)×352 (width)×325 (depth), unit: mm. The microwave oven used in this example has undergone pre-treatment: in order to radiate microwaves, cut off the shielding layer on the oven door, replace it with tinfoil, and paste a layer of conductive copper tape on the tinfoil to ensure that it is only in the desired measurement area There is leakage in one place, but no leakage in other places.

[0036] Step 1: Divide the area of ​​the microwave oven door into 3*3 areas, such as figure 2 shown;

[0037]Step 2: Fix six half-wave dipole antennas with a center frequency of 2.45GHz symmetrically in the middle of the plexiglass on the door of the ...

Abstract

The invention provides a device and method for detecting microwave leak in real time based on array antennae, and belongs to the field of microwave detection. According to the device and method for detecting microwave leak in real time based on the array antennae, the antenna array is combined with multi-classification models, the condition of microwave leak of equipment can be automatically detected in real time during usage of the microwave equipment, not only the microwave leak conditions of the portions near the antennae but also the microwave leak conditions of the portions away from theantennae can be detected, the leak positions are judged by utilizing a related classification algorithm, and after the positions are affirmed, a trained data treatment module is utilized to calculatethe magnitude of leakage energy; when the leaked energy exceeds a preset threshold value, a power supply is automatically disconnected, and the device stops working, so that the personal and propertysafety of a user is effectively guaranteed; meanwhile, the leak positions are shown, so that great convenience is brought to later maintenance work.

Description

technical field [0001] The invention belongs to the field of microwave detection, and in particular relates to a device and method for detecting microwave leakage in real time based on an array antenna. Background technique [0002] The application of microwave energy is extremely extensive, and has penetrated into almost every field of social production and life. From the application point of view, it can be divided into rapid heating and drying of materials, food sterilization and insecticide, and material modification. Therefore, various microwave equipment has become an indispensable part of modern life. It brings great convenience to daily life, production and scientific research. However, if microwave leakage occurs during the working process of microwave equipment, it will cause great harm to the human body. For example, like a microwave oven, when the microwave shielding layer is broken during work, the microwave radiation will radiate out of the furnace, and the hu...
