Abstract

The invention discloses a portable electrostatic detection device and an electrostatic detection method thereof and belongs to the field of detection. A static inductive sensor of the portable electrostatic detection device comprises a shield casing with a signal receiving window; an electrostatic signal receiving surface is arranged inside the casing; a circuit board and a signal transmitting bracket are arranged in the casing; a vibration electrode slice with a vibration source is arranged on the signal transmitting bracket; a covering sheet in parallel to a metallic electrostatic signal receiving surface is arranged at the front end of the vibration electrode slice; the rear end of the vibration electrode slice is fixedly arranged on the signal transmitting bracket or fixedly arranged on the signal transmitting bracket through the vibration source; and an electrical signal processing unit of the portable electrostatic detection device at least comprises a vibration source driving circuit, a signal amplifying circuit, a rectifier circuit and a singlechip circuit. According to the portable electrostatic detection device and the electrostatic detection method thereof disclosed by the invention, the induced electrostatic voltage is converted into alternating voltage by adopting a mechanical interrupt method for an output and subsequent detection/amplifying unit to use, and thus the electrostatic quantitative determination is realized; and in addition, the repeatability of monitored and detected data is favorable and the precision and the stability of the electrostatic detection are improved.

Description

technical field [0001] The invention belongs to the detection field, in particular to a portable detection device for detecting static electricity. Background technique [0002] Electrostatic detection meters (instruments) are commonly used in the detection of static electricity (static electricity or electrostatic discharge, etc.) in various occasions. [0003] The existing commonly used electrostatic detection meter mainly uses the principle of Faraday cylinder electrostatic induction to make a flat non-contact electrostatic induction sensor. The weak voltage induced on the sensor is amplified by operation and displayed on the terminal digital screen for people to read. [0004] Specifically, the existing flat sensor is composed of two metal sheets as the main body, and an insulating medium is added in the middle, similar to a capacitor. The detection principle is: the change of the capacitance C of the parallel plate placed in the electrostatic field causes the change of...
