Abstract

The invention discloses a data signal and DC power source collinear transmission system and method. When the front equipment will send data to the rear equipment, data signals are input into the data receiving end of the front circuit; the front circuit encodes the data input and outputs synchronous PWM signals, to boost PWM signals so that the voltage of PWM signals on the first terminal is higher than that of DC power source; the mixed signals composed of PWM signals and DC power source signals are transmitted to the rear equipment through two-wire system bus; after signals are transmitted to the rear circuit, PWM signals and DC power source signals separate, and DC power source signals are output to DC power source output interface; the rear circuit conducts analysis treatment of synchronous PWM signals input and outputs corresponding data signals. In the invention, the whole system has a centralized power supply and collinear transmission of DC power source and high-speed data signals is realized in the two-wire system, which reduces the quantity of laid cables and system cost in monitoring and control of the system.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a data signal and DC power co-linear transmission system and method. Background technique [0002] At present, video surveillance technology is widely used in monitoring, security, quality inspection and other aspects. With the development and popularization of computer and network technology and the rapid expansion of network bandwidth, video surveillance has developed into a network multimedia surveillance system, which combines digital video surveillance technology with network technology, and realizes local area network monitoring when the on-site monitoring host is unattended. Or Internet remote monitoring function. However, in similar fields such as video surveillance, non-centralized control is mostly used, with many wiring lines and high costs. Contents of the invention [0003] The purpose of the present invention is to provide a data signal and DC power sup...
