Detailed Description
Referring to fig. 1, the present embodiment provides a technical solution:
an automatic remote terminal of a distribution network comprises a main station, a substation and terminal equipment, wherein the substation is used for managing information on a feeder line, and communication management and channel burden of the main station are reduced.
The master station and the substation are connected together by using optical fibers, a single-mode optical fiber communication network is established between the master station and the substation, and information transmission is realized by using the optical fibers. The optical fiber adopts 2-core optical fibers, two ends of each optical fiber are respectively connected with an optical fiber transceiver, one optical fiber core is used for receiving data, and the other optical fiber core is used for transmitting data and is used for transmitting data between the main station and the substation. And then the optical fiber transceiver is connected with the switching hub.
Switching HUB, namely switching HUB, is called as one of the products of D-LINK, 10/100M, the principle of HUB is broadcasting and signal amplifying, so-called switching, which is to say that when the port is in 100M state, data go from 100M port to 10M port or from 10M port to 100M port, because of different rates, a switching module is needed to play a role of store-and-forward, avoid packet loss too much, and act like CPU plus buffer, but in the form of broadcasting or broadcasting is adopted between 10M port or 100M port, so as to reduce cost.
The substation is connected with the terminal equipment, and the data communication between the substation and the terminal equipment is characterized in that the data volume is smaller, the reliability is higher, and the communication distance is longer. The optical fiber communication technology is mature in application, and the optical fiber network between the substation and the terminal adopts a double-ring self-healing ring network.
The self-healing network is that the network can find errors in time without human participation and can automatically recover the loaded service in a very short time, so that the user can not feel the network failure at all. Mainly comprises a self-healing network of route protection, a self-healing network of ring protection and a self-healing network of protection by dxc (digital cross connection). The ring-shaped protection self-healing network means that the optical fiber forms a ring on the network, and each terminal device is hung on the ring. The double-ring self-healing ring network refers to a self-healing network formed by two optical fibers on a network.
The substation is provided with a substation optical fiber transceiver, and the terminal equipment is feeder terminal equipment or is connected with the feeder terminal equipment. The feeder terminal equipment of the optical fiber Ethernet is provided with a 10M/100M network port, and data is output from the network port.
The substation and the feeder terminal equipment form a communication network, the distance between each communication node is relatively short, and the distance is generally within 3 km, so that the use requirement can be met. When in connection, 4-core optical fibers are adopted to form two rings of the inner ring and the outer ring, and the directions of the two rings are opposite. A fiber optic transceiver is positioned at the substation for receiving and transmitting data, and the substation also forms a node on the ring network. The substation optical fiber transceiver is connected with a serial port communication server, and the serial port communication server is connected with the switching hub and used for transmitting information to the switching hub.
The feeder terminal equipment (ftu) is connected with a distribution transformer remote terminal and is responsible for forwarding nearby distribution transformer remote terminals (ttu) and centralized meter reading. The remote terminal (ttu) of the distribution transformer and the remote terminal (ttu) of the distribution transformer and the centralized meter reading data have low real-time requirements, so in the embodiment, the remote terminal (ttu) of the distribution transformer and the centralized meter reading data are connected to the nearby feeder terminal equipment (ftu) by using a shielded twisted pair.
The feeder terminal equipment (ftu) does not perform data decompression work and is only used as a data transmission channel.
