Preferably, described telephone exchange subsystem comprises crisis phone only switch, call conversation unit, radio unit and the administration telephone switch be connected with local telephone network respectively by junction line and dispatching of power netwoks switch, described radio unit is connected with call conversation unit by audio interface, described call conversation unit is connected with administration telephone switch with crisis phone only switch respectively by simulative telephone interface, described administration telephone switch is connected with dispatching of power netwoks switch with crisis phone only switch respectively by 2M digital interface, described crisis phone only switch is also connected to three grades of optical transmission devices.
Preferably, console and answering equipment is also connected with between described administration telephone switch and local telephone network.
Owing to have employed such scheme, the present invention makes full use of power telecom network wide coverage, feature that telecommunication circuit quality is high, for whole system provides the optical-fiber communication channel of circuitry specifications excellent performance, thus the safe and reliable fast transport of nuclear power administrative authority to important contents such as nuclear power station video, audio frequency, equipment operating datas can be ensured, the safe operation for nuclear power station is safeguarded and is provided guarantee; Its structure is simple, with low cost, has very strong practical value.
Accompanying drawing explanation
Fig. 1 is the system principle diagram of the embodiment of the present invention;
Fig. 2 is the theory diagram of the telephone exchange subsystem of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, the one that the present embodiment provides relates to vouching position operation management system, and it comprises power telecom network a, be arranged at nuclear power administrative authority one-level optical transmission device b, the secondary light transmission equipment c being arranged at State Grid Corporation of China and the three grades of optical transmission device d be arranged in each nuclear power station of (as nuclear safety office, emergency response departments at different levels etc.); Wherein, three grades of optical transmission device d are all connected power telecom network a by some Optical Fiber composite overhead Ground Wire L with secondary light transmission equipment c and are connected, and one-level optical transmission device b is connected with secondary light transmission equipment c by some city optical cable N; Simultaneously, be connected with at the input end of three grades of optical transmission device d and be formed at telephone exchange subsystem e, video monitoring subsystem f in nuclear power station and device data Monitor And Control Subsystem g, be then connected with the private telephone h corresponding with telephone exchange subsystem e, the video monitoring station i corresponding with video monitoring subsystem f and the data monitoring station j corresponding with device data Monitor And Control Subsystem g at the output terminal of one-level optical transmission device b.
Due to nuclear power station put into operation after also build up with the communication port of electric system thereupon; Therefore, the system of the present embodiment directly utilizes existing electric power communication device, one-level optical transmission device b is increased in nuclear power administrative authority, and utilize and be laid in city, incity, city optical cable N and establish a communications link between one-level optical transmission device b and secondary light transmission equipment c, meanwhile, power telecom network a and Optical Fiber composite overhead Ground Wire L is utilized to be used as secondary light transmission equipment c and the intermediate link being arranged at three grades of optical transmission device d in nuclear power station; It makes full use of power telecom network wide coverage, feature that telecommunication circuit quality is high, for whole system provides the optical-fiber communication channel of circuitry specifications excellent performance, thus the safe and reliable fast transport of nuclear power administrative authority to important contents such as nuclear power station video, audio frequency, equipment operating datas can be ensured, safe operation for nuclear power station is safeguarded and is provided guarantee, compared to public network communication and satellite communication, the system of the present embodiment has significant advantage in all many-sides such as technology realization, financial cost.
