Embodiment two
The present embodiment is the more detailed description of the information processing method to embodiment one, and specific citing description is all carried out to each process step performed by separated time point device.Fig. 4 is the schematic flow sheet of another embodiment of information processing method of the present invention, as shown in figure 4, this method can include：
401st, separated time point device starts, and power splitter receives the power supply electric energy of ustomer premises access equipment reverse power supply；Wherein, the 220V alternating currents of household internal are converted to direct current by ustomer premises access equipment by AC/DC modular converter, then the direct current is electrically communicated on twisted-pair feeder by power supply module and power integration device, it is specifically that the direct current is received by the power splitter in separated time point device by twisted-pair feeder by DC power transmission to separated time point device；The direct current is referred to as electric energy of powering by the present embodiment.
402nd, power splitter sends the power supply electric energy received to power detector；
403rd, power detector detects the power of the power supply electric energy；
Wherein, the power of power detector detection is the peak power of the power supply electric energy offer of reverse power supply.In specific implementation, power detector can carry out power detection using various ways, a kind of method of optional detection power is present embodiments provided, shown in Figure 5, Fig. 5 is the power detection schematic diagram in another embodiment of information processing method of the present invention.Fig. 5 shows the connection of power splitter and power detector internal structure, and it is that illustrate only the part circuit structure for detecting power, it is actual also to include other functional units or structure in power detector, but not shown in the Fig. 5.
For example, in the power detector, being provided with load R, switch K1 and K2, voltage detector, current detector and power calculation unit（The power calculation unit is not shown）Deng；Power splitter is connected with power detector, power splitter is actually connected to switch K1 and Κ 2, power detector is closed by controlling switch K1 and Κ 2, power splitter is connected with load R, connect the circuit shown in above-mentioned Fig. 5, the power supply electric energy that power splitter is provided will exist in the path shown in Fig. 5, and R is in the presence of the power supply electric energy for load, passes through with the presence of electric current and has voltage.The present embodiment passes through voltage
The voltage at detector detection load R two ends, and the electric current that load R is flowed through is detected by current detector.In addition, the voltage and current on the load R that the power calculation unit in power detector can obtain above-mentioned detection does the power for the electric energy of as powering that product calculation is obtained.For example, it is assumed that the voltage on load R is V0, electric current is 10, then the power for electric energy of powering is P=V0* I0.
404th, power detector sends the power of the power supply electric energy detected to DSL local side modules；Wherein, xDSL transceiver of the DSL local sides module equivalent to local side described in the present embodiment, it is mainly used in being modulated data demodulation process and the data after processing is sent into circuit or data to be processed are isolated from circuit, the DSL local side modules include DSL modem, and the DSL modems are responsible for the modulation /demodulation processing of data.The power of the power supply electric energy detected is actually to send to the DSL modem of DSL local side modules by the power detector of the present embodiment.
In the present embodiment, power detector, which sends the power of the power supply electric energy detected to the mode of DSL local side modules, can a variety of, for example, power detector can send the power detected to DC Module, then DSL local side modules are transferred to by DC Module；Or, as shown in dashed line in figure 2, power detector directly can send the power detected to DSL local side modules.
405th, DSL local sides module obtains the running parameter being adapted with power according to the power of power supply electric energy；Wherein, the present embodiment provides a kind of following acquisition modes of optional running parameter：
First, obtain with the power be adapted running parameter before, can be specifically receive power supply electric energy before, prestore at least two reference powers and with the corresponding running parameter of described two reference powers difference；
Specifically, the power consumption of DSL local side modules is relevant with several factors, it can select to influence larger several running parameters to the power consumption of DSL local side modules in the present embodiment, the present embodiment have selected three running parameters, respectively frame format parameter（For example, have in each frame several subframes be used for transmit data), signal send power language density（Power Spectrum Density, referred to as：) and data transmission peak rate PSD（I.e. maximum transceiving data speed）；Certainly, in specific implementation, other specification can also be selected, the quantity of running parameter of selection can also be changed such as selecting four parameters.When what the present embodiment was set up is the running parameter using some particular value, the power consumption of DSL local side modules and the corresponding relation of the running parameter, the power consumption of the DSL local sides module uses the peak power of DSL local side modules, and the peak power is referred to as into reference power.Referring to shown in table 1 below：
Peak power PI PSD 1
Frame format parameter 1
Data transmission peak rate 1
Peak power P2 PSD 2
Frame format parameter 2
Data transmission peak rate 2
Peak power P3 PSD 3
Frame format parameter 3
Data transmission peak rate 3
Other（Less than P3) it can not activate as shown in table 1, the present embodiment stores three reference powers in DSL local side modules in advance, equivalent to the reference power of Three Estate, it is assumed that peak power Pl values power P 2>Peak power P3;And store the corresponding running parameter of reference power difference with each grade, the present embodiment is three above-mentioned running parameters, the running parameter of some grade is used, the power consumption of DSL local side modules is exactly the corresponding peak power of the running parameter in table 1.
The determination of the value of above-mentioned running parameter corresponding with reference power, is performed according to the relation of running parameter and power consumption.For example, DSL local sides module is according to the relation of its processing DSL symbolic numbers and power consumption per second, to determine the frame format parameter of some reference power of correspondence, the more power consumptions of DSL symbolic numbers of processing per second are bigger, then the number of sub frames for the carrying data that can be set to frame format parameter when reference power value increases in every frame is more；In another example, DSL local sides module is according to user rate bandwidth and the relation of power consumption, to determine the data transmission peak rate of some reference power of correspondence, the usual bigger power consumption of user rate bandwidth is bigger, then can accordingly increase data transmission peak rate when reference power value increases；For another example can be according to the relation of DSL signal bandwidth, the general power of signal and power consumption, PSD to determine some reference power of correspondence etc..It can be combined with considering digital front-end (Digital Front End, abbreviation：DFE) and AFE(analog front end) (Analog Front End, referred to as：AFE quiescent dissipation) sets the reference power of some grade.
In addition, in the value of setting running parameter corresponding with reference power, under conditions of the certain reference power value of holding is constant, the above three running parameter of the present embodiment can preferentially meet the maximization of some running parameter value according to certain priority.Such as, if separated time point device and the distance between ustomer premises access equipment are longer, data are needed to transmit larger distance, then the preferential value for causing PSD is tried one's best greatly,
Because larger PSD is conducive to data transfer larger distance；Or, if separated time point device and the distance between ustomer premises access equipment are shorter, it can preferentially cause frame format parameter to try one's best greatly, improve the efficiency of data transfer.
Further, it can also be seen that in table 1, outside the reference power of cited Three Estate, it also show a kind of situation, i.e. when the power for electric energy of powering is less than peak power P3, DSL local sides module can not perform DSL activation processes, i.e., can not normal work, it is impossible to communicated with DSL terminal modules.Now, really a threshold value is used as equivalent to using peak power P3, the power for being only not less than the threshold value just can guarantee that the proper communication of DSL local side modules, so can avoid DSL local sides module due to unit exception caused by output power deficiency with significantly more efficient.
Then, DSL local sides module by receive power supply electric energy power, it is compared with the reference power of the Three Estate in for example above-mentioned table i of at least two reference powers of storage, it is determined that the maximum reference power of the power less than or equal to the power supply electric energy.
For example, setting peak power Pl values power P 2>Peak power P3, also, the value of the power of power supply electric energy is located between P1 and P2, i.e. peak power Pl>The power of power supply electric energy>Peak power P2, then the maximum reference power less than or equal to the power of the power supply electric energy is exactly P2.
Then, DSL local sides module regard the corresponding running parameter of the maximum reference power of determination as the running parameter adaptable with the power of the power supply electric energy.Such as, in above-mentioned example, the maximum reference power is P2, then using the running parameter corresponding with P2 in table 1 as the running parameter adaptable with the power of the power supply electric energy, i.e., PSD 2, frame format parameter 2 and data transmission peak rate 2 in table 1.
If in addition, after the power of the power supply electric energy is compared with the reference power in table 1, it is found that the power of the power supply electric energy is less than any one reference power in table 1, such as, peak power Pl values power P 2>In the case of peak power P3, the power of power supply electric energy is less than P3, then DSL local sides module no longer will be performed follow-up DSL activation processes, no longer communicated with ustomer premises access equipment, because now the power of power supply electric energy is relatively low, the power demand of DSL local side module normal works can not be met, so DSL local sides module can be avoided due to unit exception caused by output power deficiency with more efficient.
The acquisition modes for the running parameter that the DSL local sides module of above-mentioned offer is performed, are actually equivalent to according to the running parameter and the corresponding relation template of reference power prestored（That is table 1), the running parameter being adapted come the power for the electric energy that determines and power.Optionally, in specific implementation, DSL local sides module can also be calculated in real time, such as can when receiving the power of power supply electric energy, further according to the power and
The relation of running parameter and power consumption, calculates the running parameter for obtaining being adapted with the power in real time.
406th, DSL local sides module performs DSL activation processes, and sends the running parameter of determination to DSL terminal modules in the activation process；
Wherein, DSL activation processes include：G.994.1 handshake phase, channel training stage and normal data receive and dispatch the stage；In G.994. 1 and channel training stage, DSL local sides module is with DSL terminal modules by interworking parameter, and now, the running parameter obtained in 405 can be passed to DSL terminal modules by DSL local sides module.In the present embodiment, DSL local sides module can be private using time division multiplexing-orthogonal frequency（Time domain duplex- Orthogonal Frequency Division Multiplexing, referred to as：TDD-OFDM) as modulation-demodulation technique, it will start to send TDD-OFDM signals in the channel training stage.
In the scheme of the present embodiment, be with separated time point device on startup, perform the processing such as above-mentioned acquisition of power detection and running parameter, in specific implementation, DSL local sides module can also with the communication process of the DSL terminal modules of ustomer premises access equipment, the peak power that reverse power supply can be provided is periodically detected, and the running parameter of oneself is adjusted according to power is detected.Such as, in DSL local sides module and DSL terminal module communication process, the power drop of power supply electric energy may be caused for some reason, now, the power detector of separated time point device is when being periodically detected the power of power supply electric energy according to predetermined period, the output power after newest i.e. change will be obtained, and sent to DSL local side modules；DSL local sides module will adjust the running parameter being adapted with the power in real time according to the change of power, and send newest running parameter to DSL terminal modules, so that DSL terminal modules also update the running parameter of itself side, separated time point device and ustomer premises access equipment will subsequently be communicated according to the running parameter of the renewal.Wherein, time the present embodiment of predetermined period when being periodically detected is not limited, and can specifically be set according to practical application request.
The information processing method of the present embodiment, by using with power electric energy power be adapted work join power consumption effect, will not blindness use exceed output power load running parameter.
407th, separated time point device and ustomer premises access equipment use the running parameter proper communication.
