A three-dimensional electric field strength measuring device

Abstract

The invention discloses a three-dimensional electric field intensity measurement device, which belongs to the technical field of electric field intensity measurement. The device includes: a three-dimensional electric field probe, a signal receiving circuit, a program-controlled amplifying circuit, an analog-to-digital conversion circuit, a single-chip microcomputer, and a power supply. The three-dimensional electric field probe includes: three pairs of mutually perpendicular dipole antennas; and the signal receiving circuit includes: a first signal A receiving circuit, a second signal receiving circuit, and a third signal receiving circuit, the program-controlled amplifying circuit includes: a first program-controlled amplifying circuit, a second program-controlled amplifying circuit, and a third program-controlled amplifying circuit. The present invention adopts a three-dimensional electric field probe composed of three pairs of mutually perpendicular dipole antennas, so that the three-dimensional electric field intensity measuring device can measure the three-dimensional electric field intensity. Adjusting the magnification of the program-controlled amplifying circuit makes the adjustment and measurement more convenient and fast.

Description

technical field [0001] The invention relates to the technical field of electric field strength measurement, in particular to a three-dimensional electric field strength measurement device. Background technique [0002] With the development of science and technology, the application of electronic and electrical equipment has increased dramatically, and industries such as finance, radio and television, IT, electric power, telecommunications, civil aviation, railways, and medical treatment have become high-risk industries for electromagnetic radiation, and the demand for detection of electric field strength is increasing. Big. Environmental protection, measurement, safety testing, labor protection, power plants, power transmission and transformation and other fields need to use electric field testing equipment. [0003] Existing electric field sensors (such as: double ball electric field meter, rocket electric field meter and rotary vane electric field sensor, etc.) can only d...
