GPRS signal based night vision system and implementation method thereof

Abstract

The invention relates to a GPRS signal based night vision system and an implementation method thereof. The system includes a signal receiving module used for receiving first radio frequency signals sent from a GPRS base station and second radio frequency signals returned from an observation area, and outputting first signals and second signals through amplification, filtering, and analog-digital conversion; a communication module used for transmitting the first signals and the second signals output by the signal receiving module to a software module; a coordinate receiving module used for acquiring real time coordinates of the night vision system and transmitting the real time coordinates to the software module; the software module including a first sub module, a second sub module, a thirdsub module, a fourth sub module, a fifth sub module and a sixth sub module used for a series of treatment on the first signals and the second signals and performing two-dimensional time domain filtering treatment on the system real time coordinates acquired by the coordinate receiving module and 2G base station coordinates, and observing images in the observation area. The system and method provided by the invention can solve problems of low image resolution and high system price of a prior night vision system.

Description

technical field [0001] The invention relates to a night vision system based on a GPRS signal and a realization method thereof, in particular to a system and a realization method of a nighttime target imaging using a GPRS signal, belonging to the technical field of security protection. Background technique [0002] Night vision system is a kind of auxiliary system that helps users gain sight at night. It is often used in automobiles, so that drivers can obtain information on the road conditions ahead at night or in weak light conditions, and can provide drivers with early warning of potential threats ahead. [0003] Existing technical solutions related to night vision, such as "CN-201520869666-Vehicle Night Vision System", "CN201720709058 A Vehicle Night Vision System", etc. all use infrared imaging technology, and their shortcomings mainly include: [0004] (1) The infrared night vision imaging system is an active system, including an infrared signal transmitter and receiver...
