Problems solved by technology

[0002] The current way to test the electrostatic strength is to test the local voltage with a field strength tester within 1cm from the electrostatic source; the problem with this method is that the test is complicated, the overall electrostatic density of the human body cannot be evaluated, and the test efficiency is slow
[0003] The current way to measure the motion and acceleration of objects is usually to use infrared sensors to measure, but this method has the disadvantages of high technical requirements and poor anti-interference
When infrared sensors are used, in order to reduce external interference, it is usually necessary to set the sensor close to the charged object, and the infrared sensor is easily affected by the infrared reflection properties of the measured object, which limits the scope of application of the infrared sensor

Abstract

The invention discloses a motion measuring device of a live-line object, and relates to the technical field of motion measuring devices. The motion measuring device comprises a collector, a filtering and amplification unit and a detection unit connected successively; the collector comprises an antenna and an anti-interference support, and the antenna is hung on the anti-interference support via a non-conducting connecting band; the filtering and amplification unit is connected with the antenna, and comprises a low-pass filtering circuit and an amplification circuit connected successively; and the detection unit detects a current / voltage filtered and amplified by the filtering and amplification unit. A motion measuring method of an electrostatic body can realize long-distance contact-free measurement. The motion measuring device of the live-line object can capture electric field change generated during motion of the live-line body, and motion is converted into current / voltage change via filtering and amplification.

Description

technical field [0001] The invention relates to the technical field of motion measuring devices, in particular to a motion measuring device for charged objects. Background technique [0002] The current method of testing electrostatic strength is to use a field strength tester to test the local voltage within 1cm of the electrostatic source. The problem with this method is that the test is complicated, the overall electrostatic density of the human body cannot be evaluated, and the test efficiency is slow. [0003] At present, the method of measuring the motion and acceleration of an object is usually measured by using an infrared sensor, but this method has the disadvantages of high technical requirements and poor anti-interference. When the infrared sensor is in use, in order to reduce external interference, it is usually necessary to set the sensor in a position relatively close to the charged object, and the infrared sensor is easily affected by the infrared reflection p...
