Embodiment 2
The difference of the present embodiment and embodiment 1 is only:
Adapted telecommunication network configuration is divided into three layers in the present invention: core layer, convergence-level and Access Layer;
Core layer: the backbone of network, provides high-speed data to exchange and fast route convergence, has higher stability, reliability and expansibility etc.For the core layer of adapted electrical network, high-performance, highly reliable network configuration must be provided, adopt the ring network structure of many equipment redundancies.
Convergence-level: when Routing Protocol is applied to this one deck, has Fast Convergent and is easy to the features such as expansion, carrying multiple fused business.The present invention adopts OSPF Routing Protocol to realize routing convergence fast, ensures the reliability of network.
Access Layer: provide the first order of network to access, complete simple Layer2 switching, safety, QOS, multicast are all positioned at this one deck.
The present invention is made up of work space subsystem and horizontal subsystem two parts.Work space subsystem is: each transformer station is an OLT unit, its local opening and closing in one's power power distribution room is an ONU unit, place with good conditionsi adopts hub-and-spoke configuration access in radio (TDM special line or Ethernet), and the point (being cut off more difficult realization or regional rural power grids distributor point far away by physics) that cannot realize access in radio adopts MESH network to be accessed by radio network gateway.Form horizontal subsystem between transformer station, form flat grid mesh network.
Below EPON system and Zigbee wireless sub network are described in detail respectively.
EPON (PON) is a kind of single fiber bi-directional Optical Access Network adopting point-to-multipoint (P2MP) structure, and its typical topology is tree-like.Based on the EPON of Ethernet mode, be made up of the optical line terminal (OLT unit) of office side, the optical network unit (ONU unit) of user side and passive optical distribution network (ODN).
ODN provides transmission line between OLT and ONU.At up direction (ONU to OLT), the signal that ONU sends only can arrive OLT, and can not arrive other ONU; At down direction (OLT to ONU), the signal that OLT sends passs on each ONU through ODN.Improve network utilisation efficiency in order to avoid data collision, downlink data adopts broadcast transmission methods transmission data, and up direction adopts TDMA access mode transmission data, and sends the data of each ONU and arbitrate.
EPON network carries out standardization by IEEE802.3EFM working group, Ethernet and PON are combined, on the basis of EPON architectural framework, define a kind of newly, the ethernet physical layer agreement of the physical layer specification (mainly optical interface) that is applied to EPON system and expansion, to realize the TDM access of ethernet frame in point-to-multipoint PON.In addition, EPON also defines a kind of operation, maintenance and management mechanism, to realize necessary Operation, Administration and Maintenance management.
The Protocol REference Model of EPON system as shown in Figure 2.
In physical layer, adopt single fiber wavelength-division multiplex technique (descending 1490nm, up 1310nm) realize single fiber bi-directional transmission, adopt 1000BASE-PX-10U/D and 1000BASE-PX-20U/D two kinds of PON optical interfaces simultaneously, support the ultimate range transmission of 10km and 20km respectively.
At Physical Coding Sublayer, EPON system have employed original standard of gigabit Ethernet, adopts the symmetrical 1Gbit/s data rate of the up-downgoing of 8B/10B line coding and standard.
In data link layer, the function of multiple spot MAC control protocol (MPCP) is the emulation realizing point-to-point in a point-to-multipoint EPON system, supports multiple MAC entity in the client level in point-to-multipoint network, and supports the controlling functions to extra MAC.
In addition, EPON system inherits the strong autgmentability of Ethernet, supports the multiple business Integrated access such as High Speed I nternet access, voice, IPTV, TDM special line simultaneously, and has good QOS guarantee and multicast service tenability.
EPON adopts diverse ways and different optical wavelength to upstream and downstream transmissions.For downlink data, long data packet is 1518 bytes, and which ONU each packet mails to a unique identifier instruction; For upstream data, because all users share same upstream wavelength, time division multiple access must be adopted to access system to prevent the collision of light.
Between transformer station and switching station or power distribution room, set up EPON system have the following advantages:
(1) only there is the passive device such as optical fiber, optical branching device ODN between local side (OLT unit) and user's (ONU unit), without the need to being equipped with power supply, without the need to active equipment attendant, therefore greatly can reduce operation and maintenance expenses and using.
(2) EPON adopts the transformat of Ethernet, and be also the main flow of user's local area network (LAN), the two has natural amalgamation simultaneously, eliminates the cost factor that complicated transport protocol conversion is brought.
(3) adopt single fiber wavelength-division multiplex technique, only need a trunk optical fiber and an OLT, adopt in ONU side optical branching device to divide and give multiple user, therefore greatly can reduce the cost pressure of OLT and trunk optical fiber.
Set up Zigbee wireless-transmission network between power information acquisition terminal and concentrator, Zigbee network adopts star and fully connected topology, also has the Combination application of two kinds of network topologies, application of namely gathering together.Zigbee carries limited data traffic with the peak transfer rate of 250kbps.That wireless sub network has following obvious technical characterstic.
(1) low in energy consumption: in mode of operation situation, Zigbee transmission rate is low, and transmitted data amount is little, and therefore the transmitting-receiving time of signal is short, and secondly under non-operating mode, Zigbee node (i.e. power information acquisition terminal) is in park mode.Therefore, the very power saving of Zigbee node is made.
(2) transfer of data is reliable: the media access control layer of Zigbee adopts the collision-avoidance mechanism of talk-when-ready, adopts full Handshake Protocol.Signal processing means adopts DSS direct sequence spread spectrum skill, effectively improves anti-interference.
(3) network capacity is large: a Zigbee network includes at most 255 nodes, and one of them is master control, and all the other are then slaves.If by network coordinator, whole network can be supported at most more than 6400 Zigbee network nodes.
(4) fail safe: Zigbee provides data integrity inspection and authentication functions, provides three level security in the data transmission.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by referring to the preferred embodiments of the present invention, invention has been described, but those of ordinary skill in the art is to be understood that, various change can be made to it in the form and details, and not depart from the spirit and scope that the present invention limits.
