Embodiment Construction

[0040] The multi-core processor-based scalable NVR system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] Such as figure 1 , Figure 6 As shown, a multi-core processor-based scalable NVR system, the NVR system includes a main control system 110, a SATA storage system 130, an IO expansion system 140 and several expansion subsystems 120, wherein:

[0042]The main control system 110 is used to complete the input and output of data and dynamically allocate data processing tasks to each expansion subsystem;

[0043] The SATA storage system 130, which interacts with the main control system 110 through PCIE, is used to store and read data;

[0044] The IO expansion system 140 is connected with the main control system 110 through a mutually matching management interface, and is used for external expansion interface;

[0045] The expansion subsystem 120 performs data interaction with the main control system 110 throu...

Abstract

The invention discloses an extensible network video record (NVR) system based on a multi-core processor. The NVR system comprises a main control system, a serial advanced technology attachment (SATA) memory system, an input / output (IO) extended system and a plurality of extended subsystems, wherein the main control system is used for completing input and output of data as well as dynamic distribution of implementing data handling tasks to all the extended subsystems; the SATA system is in data interaction with the main control system through a peripheral component interface express (PCIE) and is used for storing and reading the data; the IO extended system is connected with the main control system through mutually matched management interfaces and is used for extending the interfaces outwards; and the extended subsystems are in data interaction with the main control system through the PCIE and are used for completing data handling tasks assigned by the main controller. The NVR system disclosed by the invention takes a multi-core processor as a core, implements data transmission with multiple extended subsystems and an extensible daughter card through a PCIE high-speed serial bus, and is strong in processing capability, high in bandwidth and low in power consumption.

Description

technical field [0001] The invention relates to the field of data processing devices, in particular to an expandable NVR system based on a multi-core processor. Background technique [0002] With the continuous development and gradual maturity of network high-definition video surveillance technology, as one of the important development directions in the future monitoring field, network high-definition surveillance camera technology represented by high-definition cameras (gun type, spherical type, hemispherical type) is used in factories, It has been widely used in monitoring fields such as enterprises and cities. For applications with a wide monitoring area, many monitoring points, and a large amount of data, users' requirements for the transmission, processing, storage, and management of high-definition digital video streams are also increasing. [0003] The VPX bus uses high-speed serial bus technology to replace the parallel bus technology of the VME bus. The VPX bus in...
