Description

Visual remote access control device and access control method thereof

technical field

The invention relates to a visualized remote access control device and an access control method thereof, in particular to a visualized remote access control device and an access control method for substations.

Background technique

With the advancement of technology, substations are developing in the direction of unmanned or less-manned on-duty. When maintenance personnel need to go to the substation to do maintenance work, the door opening is a paper-based process, and leaders at all levels need to sign. At the same time, the management department also needs to send people to the substation site to open the door for the maintenance personnel, which greatly affects the work efficiency.

The IP softswitch device is the control functional entity of the next-generation network (NGN), which provides call control and connection control functions for the services of the next-generation network that have real-time requirements. The softswitch device and various media gateways, terminals, application servers, and other Softswitch devices communicate with each other using standard protocols. Video call is through the terminal and the network, so that the callers in different places can not only hear the voice, but also see the image and background of the other party, so that the callers can obtain a variety of information that is much richer than that of the phone. The softswitch separates the control data flow and service data flow of the video call, and implements functions such as connection control, translation and routing, gateway management, call control, bandwidth management, signaling, security, and generation of call detailed records through software. The uplink interface of the network-type digital video outdoor station adopts Ethernet architecture to operate, referring to mainstream communication protocols such as Internet TCP/IP and SIP, ITU ITU H.323, and using the data communication network to complete audio and video communication and control functions.

At present, since many substations have achieved unmanned duty, certain procedures are required when entering and exiting substations. Maintenance and repair personnel need to find leaders at all levels to sign first, and the superiors will arrange substation management personnel to open the door for maintenance and repair personnel in the substation. As a result, the repair and maintenance work is often delayed, and the work efficiency of the repair and maintenance of the substation is reduced. Therefore, there is a need for an intelligent access control system, so that maintenance and repair personnel can enter the substation more conveniently, and improve the efficiency of maintenance and repair of the substation.
