Position:Embedded the system is it is a center in order to apply, soft hardware can cut down, get used to applied system to wait for omnibus strict requirement to function, dependability, cost, bulk only maneuver calculates engine system, i.e. is supervisory system act according to actual circumstances only maneuver calculates engine system.
Embedded the system is main by embedded the processor, relevant hardware that prop up, embedded the composition such as operating system and application software system, it is collect soft hardware the " of can work independently " parts of an apparatus at an organic whole. Embedded the operating system is a kind real time, support is embedded the operating system software of systematic application, it is embedded the component with very main system, include browser of interface of agreement of interface of drive of kernel of the rock-bottom drive software related to hardware, system, equipment, communication, graph, standardization to wait normally, embedded operating system in the system solid state of the relevant support sex of efficient sex, hardware, software spends real time the respect such as the special sex that reachs application has relatively outstanding characteristic. Embedded actor defect of the system: A, system is special system, the system is so small, the instruction is compact, processing rate is rapid. ROM/FLASH MEMORY of park of data of B, system, call rate fast, won't be changed, stability is good. It is good that C, system handles real time sex, performance is steady. System of D, file management more agree with much video data. It is E, difficult also that the respect waits in synchronism of video of network function, sound satisfactory.
Embedded means of video Web server, the buy inside video server embedded Web server, use embedded operating system of real time much task. After the video signal that camera delivers is digitlized by efficient compress chip, send through inside bus line inside the Web server of buy, the user on the network can watch the camera image on Web server with the browser directly, the action that accredit user still can dominate stage of camera, cloud, scene or to the system configuration undertakes operating.
Because compress video,arrive centrally with Web function inside the device with a very small bulk, can join a local area network repeatedly directly, achieve insert namely look namely, omit a variety of complex cable, installation is convenient (need to install an IP address only) , the user also need not install any hardware equipment, use a browser to be able to be watched only. Embedded of supervisory system of video Web server and other supervisory system be like next characteristics quite: A, cloth controls area capacious Embedded the Web server of supervisory system of video Web server joins a network repeatedly directly, without the limitation of wire cable length and signal attenuation, at the same time the network was not apart from a concept, abandoned thoroughly the concept of district, patulous cloth controls area. B, system is had almost infinite without seam patulous ability All equipment undertake marking with IP address, adding equipment is the expansion that means IP address only. C, can form very intricate monitoring network Use be based on embedded the supervisory system that Web server is core, on group net means means has the imitate monitoring with the tradition and the monitoring that are based on PC platform huge is different, because Web server output already finished imitate to arrive to change and be compressed of the number, use uniform agreement to be transmitted on the network, support crosses gateway, cross a path by implement long-range video is transmitted. D, function is stable and reliable, need not management of person specially assigned for a task Embedded Web server is based on actually embedded computer technology, use embedded operating system of real time much task, because video is compressed,arrive centrally with Web function again inside the device with a very small bulk, enter local area network or wide area newwork repeatedly directly, insert namely look namely, real time sex of the system, stability, dependability rises greatly, also need not management of person specially assigned for a task, special agree with the environment that unmanned value defends. E, watch at the same time when monitoring center need relatively when many camera image, to the network bandwidth can have particular demand.
