Description

Technical Field

[0001] The present invention relates to the technical field of optical network units, and in particular to a method, a device and a storage medium for dynamic power supply management of a passive optical network unit. Background Art

[0002] GPON ONU (Passive Optical Network Unit) can be configured with two specifications of power adapter, 150W or 250W, that is, there are two maximum output POE (Power over Ethernet) rated powers. When GPON ONU supplies power to PD (Powered Device), it is necessary to know the maximum PoE rated power currently supported. The usual practice is to add a detection circuit to the hardware and report the detection value to the POE management module, but this method will increase the hardware cost.

[0003] According to the design, the five LAN ports (local area network interfaces) on the GPON ONU (passive optical network unit) need to consume 330W of power when the powered device is fully loaded. When the power consumed by the powered device exceeds the maximum rated power of the GPON ONU, the operation of the ONU (optical network unit) itself will be affected, and the ONU itself may even restart due to insufficient power supply.

[0004] The traditional way to solve the above problem is that PSE (power supply equipment) allocates power to PD according to the negotiated class (level) between PD and PSE. However, because the power defined by the standard POE class is the maximum value, that is to say, there is a situation where the actual power consumed by PD may be less than the power of the negotiated class, which results in unreasonable power allocation. In the case of limited power adapter specifications, it will not be possible to power more PD devices. For example, the class negotiated between PD and GPON ONU is 4, and the maximum power supported by the class is 30W, but the actual power used by PD is 20W. According to the traditional method, pre-allocating 30W power to PD according to the class will result in a waste of 10W. Summary of the invention

[0005] In view of this, the present invention provides a method, device and storage medium for dynamic power supply management of a passive optical network unit.

[0063] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] Figure 1 The flowchart of a method for dynamic power supply management of a passive optical network unit applicable to an embodiment of the present invention is schematically shown.

[0065] See also Figure 1 The embodiment of the present invention provides a method for dynamic power supply management of a passive optical network unit, the method comprising the steps of:

[0066] S1: Get the power of the power adapter of the passive optical network unit;

[0067] Exemplarily, the step of obtaining the power adapter power of the passive optical network unit includes the following steps:

[0068] Obtaining power values ​​corresponding to each power adapter to be connected to the passive optical network unit;

[0069] Summarize and calculate the power values ​​and obtain a total power value;

[0070] The total power value is used as the power adapter power.

[0071] In an embodiment of the present application, multiple power adapters are connected to the passive optical network unit. These power adapters may be the same or different, so it is necessary to obtain the respective power on each power adapter and aggregate all the powers to obtain the total power value, which is the power of the power adapter.

[0072] S2: Determine whether the passive optical network unit is connected to a power adapter;

[0073] Exemplarily, the determining whether the passive optical network unit is connected to a power adapter comprises the steps of:

[0074] Detecting an interface signal of the passive optical network unit;

[0075] Acquire an access signal of an interface of the passive optical network unit when the passive optical network unit is connected to the power adapter;

[0076] Determining whether the interface signal conforms to the access signal;

[0077] If so, determining that the passive optical network unit is connected to the power adapter;

[0078] If not, it is determined that the passive optical network unit is not connected to the power adapter.

[0079] In an embodiment of the present application, when the passive optical network unit is connected to a power adapter, the interface generates an access signal (such as the initial signal 0 changes to 1 to indicate that the power adapter is connected), and whether the interface is connected to the power adapter can be determined by judging the change of the access signal.

[0080] S3: If yes, calculate the maximum power supply power of the passive optical network unit;

[0081] Exemplarily, the calculating the maximum power supply power of the passive optical network unit comprises the steps of:

[0082] Obtaining the power of the power adapter;

[0083] Obtaining the full load power of the optical network unit on the passive optical network unit;

[0084] The maximum power supply power is obtained by subtracting the full load power from the power adapter power.

[0085] In an embodiment of the present application, if the power of the power adapter is calculated to be 150W, and the measured full-load power of the optical network unit on the passive optical network unit is 20W, then the power adapter power is subtracted from the full-load power to obtain a maximum power supply power of 130W; if the power adapter power is calculated to be 250W, and the measured full-load power of the optical network unit on the passive optical network unit is 20W, then the power adapter power is subtracted from the full-load power to obtain a maximum power supply power of 230W; the maximum power supply power of 130W or the maximum power supply power of 230W is written to the storage unit of the passive optical network unit.

[0086] S4: If not, return to the step of obtaining the power adapter power of the passive optical network unit;

[0087] In the embodiment of the present application, if the passive optical network unit is not connected to the power adapter, the process returns to step S1.

[0088] S5: Obtaining the priority of the powered device on the passive optical network unit;

[0089] Exemplarily, the obtaining the priority of the powered device on the passive optical network unit comprises the steps of:

[0090] Obtaining an interface to which the powered device is connected on the passive optical network unit;

[0091] Obtaining the priority level of the interface;

[0092] The priority level is used as the priority of the powered device connected to the interface.

[0093] In an embodiment of the present application, each interface on the passive optical network unit will be pre-configured with a priority level. When the interface is connected to a powered device, the passive optical network unit will charge the powered device. When the passive optical network unit cannot meet the charging needs of all powered devices, in order to sort the charging priorities of a large number of powered devices, it is possible to consider directly using the priority level of each interface on the passive optical network unit as the priority level of the powered device connected to the interface. If the priority level of the interface is high, the powered device in the interface will be charged first. Otherwise, the powered device in the interface will be charged in a later order.

[0094] S6: Obtaining the requested power of the powered device;

[0095] Exemplarily, the obtaining the requested power of the powered device comprises the steps of:

[0096] Obtaining requested power values ​​corresponding to each powered device to be connected to the passive optical network unit;

[0097] Summarizing and calculating the requested power values ​​and obtaining a total requested power value;

[0098] The total requested power value is used as the requested power.

[0099] In the embodiment of the present application, multiple powered devices are connected to the passive optical network unit, and these powered devices may be the same or different, so it is necessary to obtain the respective requested power value on each powered device, and to aggregate all the requested power values ​​to obtain the total requested power value, which is the requested power. The requested power represents the power value that all powered devices need to obtain from the passive optical network unit.

[0100] S7: Allocate power supply to the powered device according to the maximum power supply, the requested power and the priority.

[0101] Exemplarily, the allocating power supply to the powered device according to the maximum power supply, the requested power and the priority comprises the steps of:

[0102] sorting all the powered devices in descending order according to the priority;

[0103] Determining whether the maximum power supply is greater than the requested power;

[0104] If so, allocating power to all the powered devices in the sequence;

[0105] If not, the last powered device in the sequence is removed, and power is allocated to all remaining powered devices in the sequence, and the process returns to the step of determining whether the maximum power supply is greater than the requested power.

[0106] In an embodiment of the present application, the control module on the passive optical network unit reads the current maximum allocable power supply power X from the storage module, and the control module detects whether there is a powered device connected to the interface. If there is a powered device connected to the interface, the control module calculates the requested power Y of all powered devices and determines whether Y is less than or equal to X. If so, it means that the passive optical network unit can power all powered devices. At this time, the control module can directly charge all powered devices with the passive optical network unit; if Y is greater than X, it means that the passive optical network unit cannot power all powered devices. At this time, the powered device with the lowest priority is selected to remove it from the charging sequence, and all remaining powered devices are powered, and then the step of determining whether the maximum power supply power is greater than the requested power is entered again.

[0107] Exemplarily, the allocating power to all the powered devices in the sequence comprises the steps of:

[0108] Obtaining the negotiation levels of all the powered devices;

[0109] Get the maximum power supply corresponding to each negotiation level;

[0110] Obtaining actual power consumption of each of the powered devices;

[0111] supplying power to all the powered devices according to the actual power consumption;

[0112] Calculating the surplus power between the maximum power supply power and the actual power consumption corresponding to all the powered devices;

[0113] All of the surplus power is recovered.

[0114] In the embodiment of the present application, after the powered device is connected to the interface, the interface will negotiate a level with the powered device, and the level is used to indicate the power range of the power supplied to the powered device through the interface, for example: if the negotiation level is level 1, the power range of the power supplied to the powered device by the interface is 0-20W; if the negotiation level is level 2, the power range of the power supplied to the powered device by the interface is 20-40W; if the negotiation level is level 3, the power range of the power supplied to the powered device by the interface is 40-60W. Therefore, each negotiation level will correspond to a maximum power supply power, for example, respectively: 20W, 40W, 60W. In order to ensure that the powered device can be adequately powered, the interface will supply power to the powered device according to the maximum power supply power. However, in reality, the actual power consumption of the powered device may be lower than the maximum power supply power. Therefore, there will be a power difference between the maximum power supply power and the actual power consumption, which is the surplus power. That is, each interface may have a surplus power. In order to save power, all surplus power needs to be recovered to power other powered devices.
