Embedded-type multi-functional video integral machine based on Hi3515 processor

Abstract

The invention discloses an embedded-type multi-functional video integral machine based on a processor Hi3515. The machine comprises an analog encoding panel, a digital encoding panel, a retransmission server panel, a display panel, an intelligent total control panel, an analog amount acquisition panel, an entrance panel, an exit panel and a serial port panel; the analog amount acquisition panel, the entrance panel, the exit panel and the serial port panel are connected with the intelligent total control panel through a RS485 bus; and the retransmission server panel is connected with the analog encoding panel, the digital encoding panel, the display panel and the intelligent total control panel through a network bus. According to the embedded-type multi-functional video integral machine based on the processor Hi3515, an omnidirectional video monitoring for a converting station is realized, functions of multiple information access and linkage output are provided, and advantages of high stability, low workload on maintenance and the like are realized.

Description

technical field [0001] The invention relates to an embedded multifunctional video all-in-one machine based on Hi3515 processor. Background technique [0002] With the continuous improvement of the automation level of the power system, in order to improve labor productivity and enhance competitiveness, a large number of unattended or less-attended modes are used in the normal production process of substations. For places such as substations, remote, real-time , A multi-dimensional video monitoring system is a necessary condition for the safe operation of substations. Embedded video codec device has become the development trend of video surveillance system due to its advantages of high reliability, clear image, fast speed, low cost and strong tailorability. Its main function is to compress and transmit the collected video image data . [0003] Currently, there are two commonly used implementations of embedded video codec devices: (1) video capture chip + DSP processor. In t...

AI Technical Summary

Problems solved by technology

Since DSP usually does not have an operating system, its control method is inflexible and has a single function, and cannot provide powerful system control and user operation functions; (2) Video acquisition chip + image compression chip + embedded processor

The scheme is complex in design, poor in stability and high in cost

In addition, most of the current embedded video codec devices can only be connected to analog cameras, and cannot realize the connection of IP cameras.
