Abstract
The utility model relates to a passive optical network optical line terminal unit specially used for power, which comprises a main control board used for realizing to control two layer switching functions, an Ethernet communicating sub-card used for providing an Ethernet communicating interface, and two pon (Passive Optical Network) communicating sub-cards used for epon (Ethernet Passive Optical Network) protocols communication. The Ethernet communicating sub-card, the pon (Passive Optical Network) communicating sub-cards and the main control board are connected in a 1.25GbpsSerdes interface way through a gigabit Ethernet. The passive optical network optical line terminal unit specially used for the power has the beneficial effects of increasing the manufacturability and reducing the cost; moreover, the pon (Passive Optical Network) communicating sub-cards can be selectively inserted according to demands to reduce unnecessary power loss.
Description
Technical field
The utility model relates to electric power system optical communication technique field, specifically, relates to the special-purpose passive optical network optical line of a kind of electric power unit OLT equipment.
Background technology
In recent years, along with the develop rapidly of national economy, the power industry of China is high speed development thereupon also.Reliable and stable communication system is the vital link of electric power system, and safety, stable operation and the management of electrical network played important guaranteeing role.
EPON (Ethernet Passive Optical Network, Ethernet passive optical network) technology combines present widely used ethernet technology and PON technology, success solves point and inserts a problem to the Ethernet of multiple spot, it with its network topology diversity, two-forty, be applicable to advantage such as IP operation, ripe terminal equipment, lower networking cost and following electrical network service application had stronger adaptability.
Because electric power system is very complicated, operational environment is more abominable, and the EPON system is in some intelligent grid link, and during as application such as power transmission line condition monitoring systems, OLT equipment also needs to be installed in the field, and power supply must adopt solar energy or storage battery power supply.Therefore the bigger power consumption of OLT equipment will increase electric supply installation cost input, and be unfavorable for engineering construction, be unfavorable for applying of EPON system.Yet present EPON system generally only considers that ONU equipment is applied to outdoor situation, for OLT equipment all give tacit consent to work in indoor, OLT equipment low-power consumption solution as yet the report.
The utility model content
The purpose of utility model
Technical problem to be solved in the utility model is to provide a kind of passive optical network optical line terminal equipment of electric power special use, realizes low-power consumption, thereby guarantees the reliable use in various power communications are used.
The technical scheme of utility model
In order to realize above-mentioned utility model purpose, the utility model is achieved by the following technical solutions:
A kind of passive optical network optical line terminal OLT equipment of electric power special use, comprise: one be used to realize to control, the master control borad of two layers of function of exchange, an ethernet communication subcard that is used to provide ethernet interface, two pon communication subcards that are used to realize the epon protocol communication.Connect with 1.25Gbps Serdes interface mode by gigabit Ethernet between described ethernet communication subcard, pon communication subcard and the described master control borad, connector adopts horizontal plug of 2mm and socket.
Comprise in the described master control borad: control unit, power supply unit and crosspoint.Described control unit, the command message of sending by serial communication or ethernet communication mode receiving management person, and transmit control signal to power supply unit according to the content of command message; Described power supply unit provides the power supply of described PON communication subcard, receives the cut-out closed procedure that carries out PON communication subcard power supply behind the signal that control unit sends; Crosspoint links to each other with the ethernet communication subcard with PON communication subcard respectively, finishes two layers of function of exchange.
This practical beneficial effect is, the special-purpose OLT equipment of electric power of the present utility model, connect with 1.25Gbps Serdes interface mode by gigabit Ethernet between ethernet communication subcard, pon communication subcard and the described master control borad, holding wire quantity is few, increase manufacturability, reduced cost, and 2 PON communication subcards can be selected to insert as required, do not influence the normal use of equipment, reduce unwanted power consumption loss.Control unit is set in master control borad, the command message of sending according to the keeper carries out the control of pon communication subcard power supply, make the PON communicator be stuck in the free of data transmission and the time be in holding state, effectively reduce equipment power dissipation, have a clear superiority in for adopting under storage battery or the solar powered environment.Power control circuit autophage power is very little, thus the power consumption when not influencing operate as normal.Though epon protocol requirement olt equipment is worked always, otherwise onu equipment just can not be finished normal registration, but communicate by letter for the power transmission line condition monitoring system, the number and the position of onu equipment are fixed, and the message that can require the onu side is not initiatively gone up and to be sent out, send out but order to go up, therefore above-mentioned low power dissipation design does not influence the operate as normal of described OLT equipment and continuous ONU equipment thereof.
Description of drawings
Fig. 1 is a composition frame chart of the present utility model.
Fig. 2 is a power control circuit schematic diagram of the present utility model.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is the composition frame chart of OLT equipment described in the utility model.Referring to Fig. 1, this OLT equipment comprises: master control borad, two PON communication subcards and an ethernet communication subcard.Master control borad comprises that cpu subsystem and GE exchange chip constitute.Connect with 1.25Gbps Serdes interface mode by gigabit Ethernet between described ethernet communication subcard, pon communication subcard and the described master control borad, connector adopts ERNI horizontal plug of ERMET 2mm and socket, above connected mode holding wire quantity is few, has increased manufacturability and has reduced cost.
Comprise in the described master control borad: control unit, power supply unit and crosspoint.Described control unit, the command message of sending by serial communication or ethernet communication mode receiving management person, and transmit control signal to power supply unit according to the content of command message; Described power supply unit provides the power supply of described PON communication subcard, receive the cut-out closed procedure that carries out PON communication subcard power supply behind the signal that control unit sends, Fig. 2 is the power control circuit of being correlated with, and the MOSFET of employing low on-resistance can effectively avoid consuming the power consumption on switching device.Control method is the CPU in the control unit, and promptly CTL1 and the CTL2 signal of MPC8247 by sending Transistor-Transistor Logic level can open or close PON communication subcard 1 and subcard 2 respectively; Crosspoint links to each other with the ethernet communication subcard with PON communication subcard respectively, finishes two layers of function of exchange.
