Anti-theft system based on power line carrier communication and dynamic image detection

Abstract

The invention discloses an anti-theft communication system based on power line carrier communication and dynamic image detection, and belongs to the technical field of communication. The anti-theft communication system based on power line carrier communication and dynamic image detection comprises an image acquisition module, an image processing system used for carrying out analysis and processing on dynamic images, a power line carrier communication module, a management server module, an image display module and an alarm module, wherein the image acquisition module is used for collecting the images, transmitting the collected images to the image processing system, when the situation that a dynamic image signal exists is found, the signal is processed, and is transmitted through the power line carrier communication module, communication is carried out between the power line carrier communication module and the management server module through power lines, the signal is displayed on a displayer, and an alarm signal is given out. According to the anti-theft communication system based on power line carrier communication and dynamic image detection, the advantages that power line carrier communication is large in communication distance, good in anti-interference capacity and high in transmission rate and reliability are effectively used by the anti-theft communication system, and the anti-theft communication system based on power line carrier communication and dynamic image detection can be used for achieving detection and burglary prevention of unwatched museums and unwatched banks.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an anti-theft system, specifically an anti-theft system based on power line carrier communication and dynamic image detection. Background technique [0002] With the advancement of science and technology and the development of the times, some unsafe hidden dangers have also appeared in our lives, especially in museums, banks, libraries and other places with precious value, there may be some hidden dangers after closing the door at night. Unsafe factors give some criminals an opportunity to cause huge losses in property and other aspects. So there are many anti-theft systems that can be applied to no man's land. [0003] The emergence of wireless sensor detection anti-theft system allows us to detect and manage in real time. However, it is necessary to regularly check whether the sensor nodes are in good working condition, whether the energy of the sensor nodes is sufficient...

Problems solved by technology

The basic modulation methods used are ASK, FSK and PSK, and the derived differential phase shift keying, minimum frequency shift keying, etc., but the denoising ability of these modulation methods is weak, especially when the noise energy is concentrated in the signal transmitted Communication will not be reliable when on the frequency band

With the expansion of the application range of low-voltage carrier communication and the continuous improvement of people's communication quality requirements, the traditional carrier communication technology has become less and less suitable for modern high-speed, large-capacity communication requirements.
