Description
Technical field
It is especially a kind of for becoming the present invention relates to a kind of visual remote access control device and its access control method
The transformer station in power station visual remote access control device and its access control method.
Background technology
With technological progress, transformer station develops to unmanned on duty or few peopleization direction on duty, when attendant needs to arrive
When maintenance work is done by transformer station, enabling bar paper feed mass flow journey is, it is necessary to look for leaders to sign.Administrative department also needs to send someone simultaneously
Opened the door to attendant to substation field, leverage operating efficiency.
IP-based switching's appliance arrangement is the control function entity of next generation network (NGN), is that next generation network has in real time
Property desired business Call- Control1 and connection control function, Softswitch and various WMGs, terminal, application service are provided
Communicated using standard agreement between device, other Softswitch.Video calling is exactly, by terminal and network, to make to be in strange land
Caller can not only hear sound each other, and can also be seen that the image and background of other side, caller is obtained
Various information that must be more far richer than phone.Softswitch separates the control data stream and business data flow of video calling,
Connection control, translation and routing, gateway management, Call- Control1, Bandwidth Management, signaling, security and generation are realized by software
The functions such as call detail record.The visual doorway machine upstream Interface of network digital is run using Ethernet architecture, with reference to international mutual
Networking TCP/IP and SIP, International Telecommunication Association ITU the main flow communication protocol such as H.323, using data communication network, can complete audio frequency and video
Communication and control function.
At present, due to many transformer stations have been realized in it is unmanned on duty, turnover transformer station when need certain flow.Dimension
Shield maintenance personal need first to look for leaders to sign, and arranges substation management personnel to transformer station for maintenance and repair works by higher level
Personnel open the door.Consequently, it is possible to often delay maintenance maintenance work so that the operating efficiency reduction of the maintenance maintenance of transformer station
.It is therefore desirable to a kind of intelligentized gate control system so that maintenance and repair personnel can more easily enter transformer station,
Improve the maintenance and repair operating efficiency of transformer station.
The content of the invention
The present invention is to avoid weak point present in above-mentioned prior art, there is provided a kind of conveniently transformer station uses
Visual remote access control device and its access control method, pass in and out transformer station, improve at any time in order to maintenance maintenance personnel
Operating efficiency.
The present invention uses following technical scheme to solve technical problem.
Transformer station's visual remote access control device, it is structurally characterized in that, including electric control door lock, digital visual
Doorway machine, IP-based switching's device, application server and control terminal；Between the electric control door lock and digital visual doorway machine
Be connected by communication bus, the digital visual doorway machine, IP-based switching's device, application server and control terminal it
Between be connected by IP network, operator to digital visual doorway machine carry out open the door request operation, by digital visual
Doorway machine sends enabling request by IP-based switching's device to control terminal, and digital visual doorway machine and control terminal pass through
Video communication system carries out video calling, and identity validation is carried out to operator, confirms the letter that be will confirm that by control terminal after identity
Breath is transferred to IP-based switching's device, the order of enabling is passed into digital visual doorway machine by IP-based switching's device, by counting
Word formula visualization doorway machine opens electric control door lock, is operator's enabling.
