System for realizing hybrid networking of soft exchange and program-controlled exchange of power dispatching

Abstract

The invention discloses a system for realizing hybrid networking of soft exchange and program-controlled exchange of power dispatching. The system comprises a main soft-exchange dispatching system and a standby soft-exchange dispatching system which respectively consist of a core gateway, a soft-exchange dispatching server, a network management server, a sound recording server and an exchanger, wherein the soft-exchange dispatching servers, the soft-exchange network management servers and the soft-exchange sound recording servers are connected with the core gateways through network lines and the exchangers; the core gateways are connected with a program-controlled exchanger (5) through 2-M relay lines, and the program-controlled exchanger (5) is connected with an analog telephone (9) through an optical transmission network (6); the exchangers are connected with an IP telephone (10) through a data bearing network (7) and a first exchanger (3), and the exchangers are connected with a soft-exchange dispatching desk (8) through the data bearing network (7) and a second exchanger (4). Through the adoption of the system disclosed by the invention, double-machine thermal standby networking (double soft-exchange systems) of the power soft-exchange dispatching system can be simultaneously realized, so that the stable running of the telephone business of power dispatching is guaranteed.

Description

Technical field: [0001] The invention relates to a system for realizing hybrid networking of electric power dispatching soft switch and program-controlled switching, and belongs to the technical field of electric power communication. Background technique: [0002] In electric power communication, whether the dispatching telephone service can run safely is related to whether the power dispatching can be carried out smoothly, and then it is related to the stability of the power grid. Therefore, the guarantee of dispatching telephone service is very important. [0003] In the traditional power communication, the dispatching telephone service is realized by the program-controlled switching system. The program-controlled switching system has been in operation for many years and can provide a safe and stable operating environment. However, the audio wiring of the program-controlled switching system is very complicated, which brings a lot of trouble to the operation and maintenanc...

Problems solved by technology

[0005] In addition, the softswitch system currently deployed in power dispatching is a stand-alone system. Once the core gateway or dispatching server fails in the stand-alone system, it will directly cause all the dispatching consoles and IP phones connected to the softswitching system to go offline. The business cannot run normally, which brings hidden dangers to the safe operation of the power grid
