Hereinafter, a kind of video monitoring of power grid wisdom building site control platform of the utility model is described with reference to the accompanying drawings Network transmission system embodiment.
The embodiment recorded herein is the specific embodiment of the utility model, for illustrating the utility model Design, is explanatory and exemplary, should not be construed as the limit to the utility model embodiment and the scope of the utility model System.In addition to the embodiment recorded herein, those skilled in the art can also be based on the application claims and specification institute is public Using obvious other technical solutions, these technical solutions include making the embodiment recorded herein any the content opened The technical solution of obvious substitutions and modifications.
The attached drawing of this specification is schematic diagram, aid in illustrating the present invention design, it is schematically indicated each several part it is mutual Relation.The same or similar reference marker is used to represent the same or similar part.
Referring to Fig. 1, a kind of network transmission system of the video monitoring of power grid wisdom building site control platform of the utility model, Including video camera 5, hard disk video recorder 4, master control server 2 and sub-control server 3.
The sub-control service that multiple video cameras 5 in possession pass through the hard disk video recorder 4, possession office in wired or wireless connection possession Device 3 and the master control server 2 at building site management and control center.
Sub-control server 3 and building site management and control center of the hard disk video recorder 4 in possession by wired or wireless connection possession office Master control server 2.
Possession office sub-control server 3 by it is wired or wireless connection building site management and control center master control server 2, wherein, Cloud platform 1 can adjust the authority of master control server 2 and sub-control server 3 and preferential in real time according to transmission of video occupied bandwidth Interim card when level is to reduce transmission of video.
It is low to carry out to master control server 2 and sub-control server 3 that video camera 5 is used for transmission vision signal (Streaming Media) respectively Delay live.
Hard disk video recorder 4 is used to receive all video cameras 5 by being wired or wirelessly connected in the hard disk video recorder 4 Vision signal, and all vision signals are generated into corresponding video file respectively, and receive master control server 2 or point When controlling the order of the transmission calling video recording of server 3, video file is sent to corresponding master control server 2 or sub-control server 3 Carry out playing back videos.
In the present embodiment, when live, video camera 5 can directly send vision signal in real time to all sub-control servers 3 and master control server 2, avoid postponing.Also, monitoring personnel can send control signal in real time by cloud platform 1, with evidence Network traffics adjust each server and receive the bandwidth distributed during video to avoid interim card.And in playback, hard disk can be passed through Video recorder 4 sends Streaming Media to sub-control server 3 and master control server 2, when a hard disk video recorder 4 due to user it is excessive and When playing video cardton, cloud platform 1 can call other idle video cassette recorders to play video automatically, be gathered around with solving network Stifled problem.
Groundwork step by the network transmission system of the video monitoring of power grid wisdom building site control platform is as follows:
Master control server 2 and sub-control server 3 networking activation and log in video cassette recorder and video camera 5 respectively.Work as shooting When machine 5 receives vision signal, sent in real time by network to each master control server 2 and sub-control server 3.Cloud platform 1 is certainly Dynamic bandwidth and the Connection Time for controlling and adjusting in real time each server-assignment.When video camera 5 automatically deposits video timing signal Store up as video file and send to hard disk video recorder 4.Multiple hard disk video recorder 4 can be mutually in step shared storage number by network According to.When user sends play-back command to hard disk video recorder 4 by cloud platform 1, hard disk video recorder 4 sends Streaming Media to use automatically The intelligent terminal (such as mobile phone, notebook, IPAD) at family.When cloud platform 1 finds 4 interim card of hard disk video recorder, automatic distribution Idle hard disk video recorder 4 continues to send Streaming Media to the intelligent terminal of user.
Can be in each entrance in construction site, processing space, interior decoration decoration, project command centre, channel monitoring, worker Dormitory, parking lot, enclosure wall etc. build high-definition video monitoring system, to get information about the detailed shape in each region in construction site scene Condition, tracks manufacturing schedule, checks the working status of worker.The most important is that the system can find security risk in advance Timely processing, so as to ensure the safety of worker to greatest extent, mitigates the loss that disaster is brought.
The video monitoring system of wisdom building site control platform is a set of remote monitoring system, by network transmission, will can be made Industry scene is transmitted to APP or the Web application in wisdom building site.Client supports laptop, tablet computer, smart mobile phone; Transmission network supports broadband, special line, 2G/3G/4G wireless networks etc..
