Description
Technical field
The invention belongs to the communication of power system technical field, relate to a kind of transmission line status monitoring transfer of data architectural framework.The main effect of this architectural framework is the high-speed transfer that realizes miscellaneous service data in the application of transmission line condition monitoring system.
Background technology
The transmission line condition monitoring system is important use system in the electric power system, this system carries out real-time monitoring by placement sensor on the transmission line relevant position to the various states and the surrounding enviroment of transmission line, to guarantee safer, stable, the operation reliably of electrical network.The various data messages of sensor acquisition need be transferred to transmission line status monitoring center by data transmission system, realize focusing on and being called by other application systems.Along with video monitoring business becomes more and more important, traditional transfer of data architectural framework based on public network is in the application demand that all can not satisfy video monitoring business data transmission on the message transmission rate or on safety of data.
Summary of the invention
Goal of the invention
The invention provides a kind of transmission line status monitoring transfer of data architectural framework.This architectural framework has been realized the high speed reliable transmission of transmission line status monitoring data by EPON (EPON) technology and wireless lan (wlan) technology are combined, and has solved problems such as the low and poor stability of public network transfer bandwidth.
Technical scheme
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of transmission line status monitoring transfer of data architectural framework comprises optical line terminal OLT, optical network unit ONU, wireless local network connecting point AP; Wherein, connect a plurality of optical network unit ONU under the optical line terminal OLT, constitute an EPON subnet; Ethernet interface by optical line terminal OLT between the subnet is interconnected; Connect wireless local network connecting point AP under each optical network unit ONU.
Utilize the fiber resource on the transmission line, can realize optical communication based on the EPON technology.The EPON technology is used on transmission line every several kilometers optical fiber access points of arranging a high speed.Owing to there is not optical fiber to insert, can use the WLAN technology to realize wireless coverage in the scope between these access points, transducer utilizes wireless channel to be linked in the fiber optic network.
Transfer of data adopts EPON and WLAN to combine.The networking mode of EPON comprises single fiber networking and two kinds of two fine networkings.The networking mode of WLAN can be traditional access point (AP) and insert client (AC) mode, also can be advanced wireless self-networking (Mesh) mode.
EPON is the optical fiber telecommunications system of a point to multiple spot.A typical EPON network comprises two kinds of equipment, and a kind of equipment is called optical line terminal (OLT), and another kind of equipment is called optical network unit (ONU).The networking mode that the EPON technology is applied to transmission line status monitoring transfer of data as shown in Figure 1.Each OLT connects a plurality of ONU down, constitutes an EPON subnet; Ethernet interface by OLT equipment between the subnet is interconnected; Each ONU connects wireless local network connecting point (AP) down.By taking such topological structure, can use optical fiber at transmission line some ONU of layout along the line and AP, thereby realize wireless coverage whole circuit.
Beneficial effect
The beneficial effects of the utility model are, the constructing communication network mode can be so that the reliability of optical communication network improves greatly in extensive, high-density deployment optical communication equipment.
The EPON network is made up of OLT equipment and ONU equipment, and typical networking mode is the communication network of a point of an OLT and several ONU formation to multiple spot.This network has the ability that anti-multiple spot lost efficacy, and any one ONU lost efficacy, and can not influence the proper communication between other ONU and the OLT.
The subnet that the EPON network constitutes makes the optical communication node on the transmission line be divided into a plurality of zones, and each zone is an EPON subnet, is connected via Ethernet interface by OLT between zone and the zone.The inefficacy of ONU equipment can not influence other zone in each zone.Though the inefficacy of OLT equipment can make the communication disruption of one's respective area, also can influence other regional transfer of data, but because the distance between the OLT is far away, article one, the OLT data of being connected on the circuit also reduce relatively, for whole link, the reliability of its communication still will be higher than traditional point-to-point optical communication.
Comprehensive above 2 points are compared traditional point-to-point optical communication mode, and network communication mode as shown in Figure 1 has higher reliability.

Fig. 2 is an EPON networking embodiment schematic diagram.
Embodiment
A concrete execution mode as shown in Figure 2.A transmission line that is about 174km is arranged, need realize wireless coverage by arranging as shown in Figure 1 communication network, so that sensor terminal on the circuit and the first-class equipment of shooting are linked in the transmission line condition monitoring system by wireless mode to the whole piece circuit.Arrange 2 OLT equipment so on the line, the transformer station at circuit two ends respectively arranges an OLT equipment.See that from left to right in first EPON subnet, the OLT apparatus arrangement connects 4 ONU equipment in transformer station; In second EPON subnet, the OLT apparatus arrangement connects 4 ONU equipment from left side transformer station 54km place; In the 3rd EPON subnet, the OLT apparatus arrangement connects 4 ONU equipment from left side transformer station 113km place; In the 4th EPON subnet, the OLT apparatus arrangement is transformer station on the right, connects 5 ONU equipment.
