Abstract

The invention discloses an induction type electromagnetic leakage detection device and method. The induction type electromagnetic leakage detection device is characterized by comprising an X-axis magnetic field detection circuit, a Y-axis magnetic field detection circuit and a Z-axis magnetic field detection circuit, an MCU (Micro-programmed Control Unit) processing unit and an upper computer, wherein the X-axis magnetic field detection circuit, the Y-axis magnetic field detection circuit and the Z-axis magnetic field detection circuit are respectively and correspondingly connected with input ends of three signal processing units; the output ends of the three signal processing units are connected with the analog input end of an AD (Analog / Digital) converting circuit; the digital output end of the AD converting circuit is connected with the I / O (Input / Output) port of the MCU processing unit; the output end of a power supply circuit is connected with the power supply end of the MCU processing unit; a data storage circuit and a liquid crystal display circuit are respectively connected with the MCU processing unit; and the MCU processing unit is communicated with the upper computer through infrared transmission. The invention provides the induction type electromagnetic leakage detection device and method which are convenient for a tester to judge results, thereby solving the problems that whether the electromagnetic leakage of an electronic product exceeds the standard cannot be judged in real time when the electromagnetic leakage of the electronic product is detected in prior art, and the tester is put into inconvenience.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic detection, and in particular relates to an inductive electromagnetic leakage detection device and a detection method thereof. Background technique [0002] With the development of science and technology, people are using more and more electronic devices in production and life. When these devices are running, they often generate some useful or useless electromagnetic energy, which will affect other devices or systems. work, this is electromagnetic interference. [0003] Electromagnetic leakage will reduce the working performance of electronic equipment: According to incomplete statistics, the failure of electronic and electrical equipment all over the world due to electromagnetic interference causes hundreds of millions of dollars in economic losses every year. For example, the interference of high-power electromagnetic signals such as BP aircraft transmitters affects the normal take-off a...
