Abstract
The invention provides an electrostatic imaging-based electric field early warning method and an electrostatic imaging-based electric field early warning device, and the method comprises the steps: sensing a charge signal of the surface of a detected object through each electric field sensitive element in an electrostatic sensor, so as to obtain each analog charge signal; obtaining digital charge signal values corresponding to the analog charge signals and sensitive element surface electric field values of the electric field sensitive elements; inputting the surface electric field value of each sensitive element or each digital charge signal value into an electric field intensity-position distribution table to obtain a charge distribution diagram of the surface of the measured object; and comparing the digital charge signal values according to a preset condition, and generating an electric field early warning instruction and / or a fault instruction according to a comparison result. According to the invention, the charge distribution diagram of the detected object can be accurately obtained, and whether an electric field early warning instruction and / or a fault instruction are / is generated or not can be judged according to the analysis result of the digital charge signal value while the charge distribution diagram is obtained.
