Dual-digital signal processing (DSP) visual tracking remote monitoring system

Abstract

The invention relates to the technical field of security monitoring and provides a dual-digital signal processing (DSP) visual tracking remote monitoring system, which comprises an electric head device (1), a video decoding module (2) and a DSP1 module (3). Image data acquired by the electric head device (1) is decoded by the video decoding module (2) and then input to the DSP1 module (3). The system is characterized by also comprising a DSP2 module (5), a driving module (4), a central processing unit (CPU) module (6) and a network communication module (7), wherein the DSP2 module (5) is connected with the driving module (4) for outputting a driving electrical signal; the driving module (4) has three MC33886 chips and a driving circuit of an H bridge in order to control an image acquisition element within the electric head device (1) to do upward and downward, leftward and rightward, forward and backward displacements; the DSP1 module (3) is connected with the DSP2 module (5) via a multi-channel buffer serial port (McBSP) port; and the CPU module (6) is connected with the network communication module (7) and accesses the internet via the network communication module (7) and a network interface, so that an image signal acquired by the electric head device (1) can be transmitted to a remote server in real time.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring, in particular to a system for automatically tracking and monitoring dynamic targets. Background technique [0002] Digital Signal Processing (DSP for short) is a unique microprocessor, a device that processes a large amount of information with digital signals. Its working principle is to receive an analog signal, convert it into a digital signal of 0 or 1, then modify, delete, and strengthen the digital signal, and interpret the digital data back to analog data or the actual environment format in other system chips. Not only is it programmable, but its real-time running speed can reach tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors. It is an increasingly important computer chip in the digital electronic world. DSP microprocessors (chips) generally have the following main features: one multiplication and one addition ca...
