Abstract
This invention relates to a method for realizing power-down mode on optical network units (ONU) of passive optical networks including: an internal CPU of an ONU chip accesses an internal register of an exchange chip via MDIO to read related information in it and get if the ONU is connected with a network line or data flows flow through it, if not, chip ONU sends a switch signal for configuration to the data signal pin of a trigger, which will output an enable signal to a DC-DC converter to turn it to a power down mode and turns off the voltage provided to chip ONU and converted voltage.
Description
Technical field
The present invention relates to EPON (GEPON), particularly relate to a kind of method that on the optical network unit of EPON, realizes battery saving mode.
Background technology
EPON (GEPON) based on gigabit Ethernet is the optical-fiber network of a kind of point to multiple spot, and the passage that refers to signal is all finished by passive device between from the source to the destination node.It is the point-to-multi-point system that is made of OLT (optical line terminal), ONU (optical network unit) and ODN unit such as (Optical Distribution Networks).As shown in Figure 1.
Adding POWER DOWN pattern, is to consider that some user when ONU is idle, forgets and cuts off the electricity supply, and causes ONU to be in the state that powers on always.So, one: wasted electric power resource, brought economic loss to the user; Two: ONU is in running order always, has shortened its useful life.So when ONU does not have netting twine connection or free of data flow to flow through, make it enter POWER DOWN pattern, can save unnecessary power consumption, increase the service life.
Existing technical scheme is to add single-chip microcomputer by the outside to carry out circuit control.As shown in Figure 2, when needs entered Power Down pattern, single-chip microcomputer is given there emerged a the innernal CPU of signal to the ONU chip, and CPU turn-offs the power supply to the inside chip power supply, thereby reaches the effect of power saving.When will enter operate as normal, be there emerged a the innernal CPU of signal by single-chip microcomputer equally to the ONU chip, wake CPU up, CPU will open again to the power supply of inside chip power supply, thereby enter normal mode of operation.
The defective of prior art scheme is as follows:
1, employing adds single-chip microcomputer and controls the sequential that enters POWER DOWN pattern, has improved the design cost of entire circuit.
When 2, control entered POWER DOWN pattern, the power consumption of entire circuit also will comprise the power consumption of single-chip microcomputer, so truly do not reach the lowest power consumption of circuit.
3, add single-chip microcomputer, circuit board certainly will will be done corresponding expansion, makes the design of entire circuit complicated.
4,, reduced the reliability of entire circuit owing to the increase of components and parts in the circuit.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of method that realizes battery saving mode on the optical network unit of EPON for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of method that realizes battery saving mode on the optical network unit of EPON is characterized in that this method may further comprise the steps:
A.ONU (optical network unit) chip internal CPU is by the internal register of MDIO (management data input/output interface) visit exchange chip, read the relevant information in the register, obtain the relevant information whether ONU has netting twine to connect or whether have data traffic to flow through;
B. when ONU did not have netting twine connection or free of data flow to flow through, the ONU chip was configured for switching signal of flip-flop data signal pin;
C. can export trigger at this moment an Enable (enabling) signal and make it enter POWER DOWN (power saving) pattern for DC-DC Converter (DC-DC converter), turn-off and give chip voltage that the ONU chip provides and the voltage of changing out;
D. the voltage to exchange chip power supply exists all the time, and when ONU has netting twine to connect to go up or has data traffic flow out-of-date, exchange chip reconfigures for the conversion of signals of a high-low level of data-signal pin of trigger to trigger;
E. can export trigger at this moment an Enable signal and make it enter POWER ON (powering on) pattern for DC-DC Converter, the changing voltage of chip voltage being provided and changing out for the ONU chip, thereby the normal operating conditions of entering.
Described ONU chip can adopt PAS6201 or PAS6001.
Described exchange chip can adopt Marvell6061.
Described trigger can adopt d type flip flop.
It is the switching signal of a high and low level that described ONU chip is given the switching signal of d type flip flop data-signal pin.
Described chip voltage can be 3.3V voltage.
Described changing voltage can be 1.8V voltage.
Described voltage to the exchange chip power supply can be 3.3V voltage.
Compared with prior art, the present invention has the following advantages:
1. do not adopt to add single-chip microcomputer and control the sequential that enters POWER DOWN pattern, but control the sequential that enters POWER DOWN pattern by d type flip flop being configured at the original exchange chip of circuit.Greatly reduce the design cost of circuit.
2. when control entered POWER DOWN pattern, the power consumption the when power consumption of entire circuit compares with Single-chip Controlling will significantly reduce.Lowest power consumption is about 800mW.
3. need not to add single-chip microcomputer in addition, saved segment space on the circuit board, optimized the design of entire circuit.
4. owing to the minimizing of components and parts in the circuit, improved the reliability of entire circuit.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 3, present embodiment adopts following scheme:
1.ONU chip internal CPU reads the relevant information in the register by the internal register of MDIO visit exchange chip, obtains the relevant information whether ONU has netting twine to connect or whether have data traffic to flow through.
2. when ONU did not have netting twine connection or free of data flow to flow through, the ONU chip can be given the switching signal (according to the trigger difference of selecting, carrying out different configurations) of a high and low level of d type flip flop data-signal pin.
Make it enter POWER DOWN pattern for DC-DC Converter 3.D trigger can be exported an Enable signal at this moment, the voltage of 3.3V voltage that provides to the ONU chip and the 1.8V that changes out is provided.
4. exist all the time to the 3.3V voltage of exchange chip power supply this moment.When the ONU netting twine connect to be gone up or have data traffic flow out-of-date, exchange chip can be given the switching signal of a high and low level of data-signal pin of d type flip flop.
Make it enter POWER ON pattern for DC-DC Converter 5.D trigger can be exported an Enable signal at this moment, the voltage of 3.3V voltage that provides to the ONU chip and the 1.8V that changes out is provided, thus the normal operating conditions of entering.
