The invention provides a streaming media server of an embedded Linux shearing system, which comprises a central control module POWERPC, a high-speed communication module, a data storage module, a low-speed communication module and a power supply control module. The streaming media server has the advantages that: the reproduction and distribution of audio and video streaming media are realized in a transformer substation remote monitoring system of a power system based on a network process POWERPC for the first time; and the processor POWERPC has wide applications in switch and router products in field of communication. Compared with the PC system, Windows operation system and conventional streaming media server, which use an X86 platform, the streaming media server of the invention has the advantages that: the cost is low, namely the cost of the streaming media server is 50 percent lower than the PC system with the same performance; and the power consumption of the streaming media server is over 80 percent lower than the PC system. The streaming media server has high stability and belongs to an embedded product. The streaming media server is safer for the adopted shearing linux kernel technique makes the safety of the system improved greatly compared with the Windows system.
Description
technical field [0001] The invention relates to a streaming media server based on an embedded Linux tailoring system, which is suitable for the application requirements of a remote video monitoring system of a power system substation, and belongs to the technical field of network communication. Background technique [0002] The substation network video monitoring system (also known as "remote viewing system") preliminarily solves the problem of remote monitoring after the substation is "unattended". By setting up a streaming media server in the monitoring center, simultaneous online remote video monitoring of multiple substations is realized. The traditional streaming media service system based on x86PC architecture Windows operating system is lacking in security, stability, execution efficiency and power consumption. The inevitable trend of requirements, the unattended, comprehensive management and safety management of substations are the only way to modernize the power gr...
