In practical applications, the DSL central office module of the branch point device usually sets working parameters according to the actual data transmission requirements during work. The working parameters are the parameters used by both parties when communicating with the DSL terminal module, such as frame format, data transfer rate, etc. However, the DSL central end module relies on the power provided by the above-mentioned reverse power supply to work, and sometimes the power of the reverse power supply is low, which cannot meet the power required by the DSL central end module to use certain operating parameters, resulting in DSL central end.

detailed description

Firstly, the system environment used by the information processing method and equipment of the embodiment of the present invention is described. FIG. 1 is a diagram of the FTT dp system architecture applied in the embodiment of the information processing method of the present invention. As shown in FIG. 1 , in the system architecture of FTT dp, Optical fiber is used for transmission from the central office to the distribution point equipment, and copper wires are used for transmission from the distribution point equipment to the inside of the user's home. The copper wires are, for example, twisted-pair wires.

Figure 2 is a connection structure diagram between the line distribution point device in Figure 1 and the user end device inside the user's home. As shown in Figure 2, it shows the respective structures of the line distribution point device and the user end device, and connection between. Wherein, the client device is connected to the computer on the user side, and the client device may include: a DSL terminal module 11, a power integrator 12, a power supply module 13 and a DC/AC conversion module 14; the distribution point device includes: a power detector 21 , DSL central office module 22 . The user terminal equipment and the distribution point equipment are connected through a twisted pair 30 . In addition, the branching point device may also include: a power splitter, a DC module, an optical fiber transmission module, and the like.

In this embodiment, the distribution point device is powered by the user end device to provide electric energy. Specifically, the user end device converts the 220V AC power inside the home into DC power through the DC/AC conversion module 14, and then through the power supply module 13 and The power integrator 12 transmits the direct current to the twisted pair 30, and the twisted pair 30 transmits the direct current to the distribution point device. On the distribution point device, the power splitter separates the direct current to the power detector 21, and the power detector 21 can perform power detection on the direct current, and transmit the direct current to the direct current module, and the direct current module controls the DSL central office module 22, the optical fiber The transmission module supplies power. The DSL central office module 22 uses the power supply to communicate with the DSL terminal module 11 in the user end equipment to realize high-speed data transmission.

The information processing method described in the embodiment of the present invention is executed by the point-of-line device, and is used to explain the processing according to the power after the point-of-line device receives the power supplied by the user end device during reverse power supply ; The information processing device according to the embodiment of the present invention is a branching point device. The details are as follows:

Embodiment one

FIG. 3 is a schematic flowchart of an embodiment of the information processing method of the present invention. The method of this embodiment is executed by the line-breaking point device, and the processing method of this embodiment is described in conjunction with the structure of the line-breaking point device shown in FIG. 2 ; As shown in Figure 3, the method may include:

301. Receive the power supply power provided by the user terminal equipment;

Wherein, the power splitter of the distribution point device receives the power supply power transmitted by the twisted pair, such as DC power reversely supplied by the user end equipment. The power splitter sends the received power supply power to the power detector in the distribution point device.

302. Detect the power of the power supply electric energy;

Wherein, the power detector detects the power of the power supply electric energy, and the power refers to the maximum power that the power supply electric energy can provide. In specific implementation, the power detector can detect the maximum power that the power supply can provide in various ways, for example, it can detect the voltage and current of the load under the action of the power supply, and obtain the maximum power by the product of the voltage and current .

303. According to the power of the power supply electric energy, acquire the working parameters of the digital subscriber line DSL communication suitable for the power;

Among them, the power detector will send the maximum power that can be provided by the detected power supply to the DSL central office module in the branch point device, and the DSL central office module will obtain the same power as the power supply according to the power of the power supply. Compatible with the working parameters of the DSL communication.

When the DSL central office module communicates with the DSL terminal module of the user end equipment, both parties use the same working parameters, such as frame format, power spectral density and data transmission rate, etc. These working parameters are determined by the DSL central office module. Determined and passed to the DSL termination module during the DSL activation process. The DSL terminal module in the client equipment can adjust the frame format and data transmission rate when it communicates with the DSL central office module according to the working parameters, and communicate with the DSL central office module according to the format specified by the working parameters.

Using different working parameters will make the power consumption of the DSL central office module different, and the corresponding power requirements of the DSL central office module for power supply power are also different; for example, the higher the data transmission rate determined by the DSL central office module, the lower its power consumption The larger it is, the greater the power provided by the power supply is required. Otherwise, if the power provided by the power supply is low, it cannot meet the power consumption requirements of the DSL central office module for normal operation, which may cause abnormality of the distribution point equipment.

Therefore, in this embodiment, the DSL central office module will obtain the working parameters suitable for the power according to the actually detected power of the power supply electric energy. The adaptation mentioned here means that the power consumption required for communication by using the working parameters can be supported by the power of the power supply electric energy. For example, suppose the DSL central office module adopts certain working parameters, which The resulting power consumption is 20w. If the power of the power supply is greater than 20w, such as 22w, it can be said that the power of the power supply is compatible with the operating parameters; and if the power of the power supply is less than 20w, such as 15w, then At this time, the power of the power supply will not be able to support the normal operation of the DSL local end module, which may cause equipment abnormality. At this time, the power of the power supply is incompatible with the working parameters.

304. Perform DSL communication with the client equipment by using the working parameters.

Wherein, after the DSL central office module of the distribution point device determines the working parameter suitable for the power of the power supply, it will subsequently use the working parameter to communicate with the DSL terminal module of the user end device. Specifically, the distribution point device will receive the power supplied by the user end equipment when it is started. After the DSL central office module determines the working parameters according to the power of the power supply, it will start the DSL activation process with the DSL terminal module. , and pass the determined working parameters to the DSL terminal module during the handshake phase and channel training phase during the DSL activation process, and in the normal data sending and receiving phase, both the DSL central office module and the DSL terminal module will perform data communication according to the working parameters.

It should be noted that the execution of the information processing method described in the embodiment of the present invention may be when the point-of-line device starts up, or during the communication between the point-of-line device and the client device. For example, when the distribution point device is started, it receives the electric energy of the reverse power supply, and performs the above-mentioned power detection and acquisition of working parameters and other processing; for another example, the distribution point device can A detection period is set to periodically detect the power of the power supply and update the working parameters used according to the detected power. In specific implementation, the branching point device may execute the processing method of this embodiment only when the device is started, or only periodically execute the processing method of this embodiment during the communication process, or execute it both at startup and periodically during the communication process implement.

In the information processing method of this embodiment, the line-distributing point device acquires working parameters suitable for the power according to the actually detected power of the power supply electric energy, so that the working parameters used by the line-dividing point device for data communication can be The parameters are matched with the power provided by the power supply. The power supply can support the work of the distribution point equipment and meet the communication requirements of the distribution point equipment, thus avoiding equipment failure caused by the insufficient power supply of the distribution point equipment.

Embodiment two

This embodiment is a more detailed description of the information processing method in Embodiment 1, and each processing step performed by the line-dividing point device is described with a specific example. Fig. 4 is a schematic flowchart of another embodiment of the information processing method of the present invention. As shown in Fig. 4, the method may include:

401. The branch point device is started, and the power separator receives the power supply power supplied by the user end device in reverse;

Among them, the user end equipment converts the 220V AC power inside the home into DC power through the DC/AC conversion module, and then transmits the DC power to the twisted pair through the power supply module and the power integrator, and the twisted pair transmits the DC power to the distribution point The device, specifically, receives the direct current through the power separator in the branch point device; this embodiment refers to the direct current as power supply power.

402. The power separator sends the received power supply electric energy to the power detector;

403. The power detector detects the power of the power supply electric energy;

Wherein, the power detected by the power detector is the maximum power provided by the reverse power supply electric energy. In specific implementation, the power detector can perform power detection in a variety of ways. This embodiment provides an optional method for detecting power, as shown in FIG. Schematic diagram of the power detection. Figure 5 shows the connection between the power splitter and the internal structure of the power detector, and only shows a part of the circuit structure for detecting power. In fact, other functional units or structures may be included in the power detector, but in This is not shown in FIG. 5 .

For example, in the power detector, a load R, switches K1 and K2, a voltage detector, a current detector, and a power calculation unit (the power calculation unit is not shown) are provided; the power separator is connected to the power detector, In fact, the power splitter is connected to the switches K1 and K2, the power detector is closed by controlling the switches K1 and K2, the power splitter is connected to the load R, and the circuit shown in Figure 5 above is connected, the power splitter provides The power supply will exist in the path shown in Fig. 5, and the load R will have current and voltage under the action of the power supply. In this embodiment, a voltage detector is used to detect the voltage across the load R, and a current detector is used to detect the current flowing through the load R. In addition, the power calculation unit in the power detector can calculate the product of the detected voltage and current on the load R to obtain the power of the power supply. For example, assuming that the voltage on the load R is V0 and the current is I0, the power of the supplied electric energy is P=V0*I0.

404. The power detector sends the detected power of the power supply electric energy to the DSL central office module;

Wherein, the DSL central office module described in this embodiment is equivalent to the xDSL transceiver at the central office, and is mainly used for performing modulation and demodulation processing on data, and sending the processed data to the line or separating the data to be processed from the line. For data, the DSL central office module includes a DSL modem, and the DSL modem is responsible for data modulation and demodulation processing. The power of the power supply detected by the power detector in this embodiment is actually sent to the DSL modem of the DSL central office module.

In this embodiment, the power detector can send the detected power of the power supply to the DSL central office module in various ways. For example, the power detector can send the detected power to the DC module, and then the DC module can transmit the detected power. to the DSL central office module; or, as shown by the dotted line in FIG. 2 , the power detector can directly send the detected power to the DSL central office module.

405. The DSL local end module acquires working parameters corresponding to the power according to the power of the power supply;

Among them, this embodiment provides the following optional way of obtaining working parameters:

Firstly, before acquiring the working parameters adapted to the power, specifically, before receiving the power supply, at least two reference powers and working parameters respectively corresponding to the two reference powers are pre-stored;

Specifically, the power consumption of the DSL central office module is related to many factors. In this embodiment, several operating parameters that have a greater impact on the power consumption of the DSL central office module can be selected. Three operating parameters are selected in this embodiment , are the frame format parameters (for example, how many subframes are used to transmit data in each frame), the power spectral density (Power Spectrum Density, referred to as: PSD) of signal transmission, and the peak rate of data transmission (ie, the maximum transmission and reception data speed); of course, in specific implementation, other parameters can also be selected, and the number of selected working parameters can also be changed, for example, four parameters can be selected. This embodiment establishes the corresponding relationship between the power consumption of the DSL local end module and the working parameter when a specific value of the working parameter is adopted, and the power consumption of the DSL local end module adopts the peak power of the DSL local end module, and This peak power is referred to as reference power. See Table 1 below:

Table 1 Reference power and corresponding working parameters

As shown in Table 1, this embodiment pre-stores three reference powers in the DSL central office module, which are equivalent to three levels of reference power, assuming peak power P1>peak power P2>peak power P3; The working parameters corresponding to the reference power of each level, the present embodiment is the above three working parameters, that is, using a certain level of working parameters, the power consumption of the DSL central office module is the peak power corresponding to the working parameters in Table 1.

The above determination of the value of the working parameter corresponding to the reference power is performed according to the relationship between the working parameter and the power consumption. For example, the DSL central office module determines the frame format parameters corresponding to a certain reference power according to the relationship between the number of DSL symbols processed per second and power consumption. The more DSL symbols processed per second, the greater the power consumption. The reference power value When it is increased, the frame format parameter can be set so that the number of subframes carrying data in each frame is more; for another example, the DSL central office module determines the data transmission corresponding to a certain reference power according to the relationship between the user rate bandwidth and power consumption Peak rate, usually the greater the bandwidth of the user rate, the greater the power consumption, then the peak rate of data transmission can be increased correspondingly when the reference power value increases; another example, it can be determined according to the relationship between DSL signal bandwidth, total signal power and power consumption PSD corresponding to a certain reference power, etc. A certain level of reference power may also be set in consideration of static power consumption of a digital front end (Digital Front End, DFE for short) and an analog front end (Analog Front End, AFE for short).

In addition, when setting the value of the working parameter corresponding to the reference power, under the condition of keeping a certain reference power value unchanged, the above three working parameters in this embodiment can be prioritized to satisfy a certain work according to a certain priority. Maximize the value of the parameter. For example, if the distance between the distribution point device and the user end device is long, and the data needs to be transmitted over a long distance, then it is preferable to make the PSD value as large as possible, because a larger PSD is conducive to data transmission over a longer distance; Alternatively, if the distance between the branch point device and the user end device is relatively short, the frame format parameter may be given priority to be as large as possible to improve the efficiency of data transmission.

Furthermore, it can also be seen from Table 1 that in addition to the three levels of reference power listed, it also shows a situation, that is, when the power of the power supply is lower than the peak power P3, the DSL central office module It will not be able to perform the DSL activation process, that is, it will not work normally and cannot communicate with the DSL terminal module. At this time, it is actually equivalent to taking the peak power P3 as a threshold, and only the power not lower than this threshold can ensure the normal communication of the DSL central office module, which can more effectively avoid the failure of the DSL central office module due to insufficient power supply. The device is abnormal.

Next, the DSL central office module compares the power of the received power supply electric energy with at least two stored reference powers, such as the reference powers of the three levels in the above-mentioned Table 1, and determines the maximum value of the power less than or equal to the power supply electric energy. the reference power.

For example, assuming that peak power P1>peak power P2>peak power P3, and the value of the power of the power supply is between P1 and P2, that is, peak power P1>power of power supply>peak power P2, then it is less than or equal to all The maximum reference power of the power of the power supply electric energy is P2.

Then, the DSL central office module uses the determined working parameter corresponding to the maximum reference power as the working parameter adapted to the power of the power supply. For example, in the above example, the maximum reference power is P2, then the operating parameters corresponding to P2 in Table 1 can be used as the operating parameters suitable for the power of the power supply electric energy, that is, PSD2 in Table 1 , frame format parameter 2 and data transmission peak rate 2.

In addition, if after comparing the power of the power supply with the reference power in Table 1, it is found that the power of the power supply is less than any of the reference powers in Table 1, for example, peak power P1>peak power P2>peak In the case of power P3, if the power of the power supply is less than P3, the DSL central office module will no longer execute the subsequent DSL activation process, and will no longer communicate with the user end equipment, because the power of the power supply is low at this time and cannot meet the requirements of DSL. The power requirements for the normal operation of the central office module can more effectively avoid equipment abnormalities caused by insufficient power supply of the DSL central office module.

The method of obtaining the working parameters performed by the DSL central office module provided above is actually equivalent to determining the work that is compatible with the power of the power supply according to the template of the corresponding relationship between the working parameters and the reference power stored in advance (that is, Table 1). parameter. Optionally, in specific implementation, the DSL central office module can also calculate in real time. For example, when receiving the power of the power supply, it can calculate in real time the power corresponding to the power according to the power and the relationship between the working parameters and the power consumption. Adapted working parameters.

406. The DSL central office module executes the DSL activation process, and sends the determined working parameters to the DSL terminal module during the activation process;

Among them, the DSL activation process includes: G.994.1 handshake stage, channel training stage and normal data sending and receiving stage; in the G.994.1 and channel training stage, the DSL central office module and the DSL terminal module will exchange working parameters. At this time, the DSL central office The module will pass the working parameters obtained in 405 to the DSL terminal module. In this embodiment, the DSL central office module can use time division multiplexing-orthogonal frequency division multiplexing (Timedomain duplex-Orthogonal Frequency Division Multiplexing, referred to as: TDD-OFDM) as the modulation and demodulation technology, and will start to send TDD during the channel training phase. - OFDM signal.

In the solution of the present embodiment, when the line-dividing point device is started, the processing such as the above-mentioned power detection and the acquisition of the working parameters is performed. During the communication process, periodically detect the maximum power that the reverse power supply can provide, and adjust its own working parameters according to the detected power. For example, during the communication process between the DSL central office module and the DSL terminal module, the power of the power supply may drop for some reason. At this time, the power detector of the distribution point device periodically detects the power of the power supply according to the preset cycle , it will get the latest changed power supply and send it to the DSL central office module; the DSL central office module will adjust the working parameters suitable for the power in real time according to the power change, and send the latest working parameters to The DSL terminal module enables the DSL terminal module to also update its own working parameters, and the branch point device and the user end device will subsequently communicate according to the updated working parameters. Wherein, the time of the preset period during periodic detection is not limited in this embodiment, and may be specifically set according to actual application requirements.

The information processing method of this embodiment not only avoids equipment failures caused by insufficient power supply, but also saves power consumption by using working parameters that are compatible with the power of the power supply. Operating parameters that exceed the power load of the power supply.

407. The branch point device communicates normally with the user end device using the working parameters.
