Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of access network optical communication, and particularly relates to a remote power supply configuration system and method for an ONU device and a storage medium. BACKGROUND

[0002] With the popularity of gigabit broadband and 4K / 8K video monitoring services, the traditional access network is facing three major pain points:

[0003] Firstly, the existing ONU needs to be manually configured by the operation and maintenance personnel in terms of PoE port power upper limit, priority and energy-saving period when opening services on site, or the ONU configuration needs to be temporarily modified manually when the type of terminal device connected to the ONU does not match the pre-uniform imported configuration in actual use, which cannot dynamically adjust the configuration according to the type of terminal device. Manual configuration leads to exponential growth of manual labor hours and is prone to errors. For example, ONU can be applied to mines, factory workshops and breeding farms, and the type of terminal device connected to ONU in such scenarios is relatively fixed and can be pre-configured. However, when ONU is applied to temporary scenarios such as large-scale sports meetings, concerts and scientific expeditions, the type of terminal device connected to ONU may be different each time, and the configuration required is also different.

[0004] Secondly, the existing ONU needs to take power by itself, and generally adopts a multi-level PoE switch cascade mode to supply power to terminal devices such as cameras, APs and sensors, which is complex in wiring, has many nodes and many fault points. At the same time, the remote camera and the ONU are often connected by a 30-100 meter copper cable, and signal attenuation, lightning surge and EMI interference cause unstable link, resulting in high operation and maintenance cost.

[0005] Further, the ONU for remote power supply is preferably provided with good waterproof and antifouling performance to cope with adverse weather and environmental conditions.

[0006] Therefore, there is an urgent need for an ONU solution that takes power through an optical and electrical composite cable and dynamically configures the PoE LAN port through a cloud server to supply power to directly connected terminal devices, while having waterproof and antifouling properties. SUMMARY

[0007] In view of the above deficiencies in the prior art, the remote power supply configuration system and method for an ONU device and the storage medium provided by the present application solve the problem that the ONU device needs to be manually set with PoE parameters when remotely opening services in batches in the traditional method, and cannot provide differentiated and flexible power supply solutions for terminal devices. At the same time, the traditional PoE solution has a long link and cannot be flexibly switched according to the use scenario of the ONU device, and the existing ONU device needs to take power by itself, which is affected by the use environment and makes the power supply line complex, thereby increasing the operation and maintenance cost.

[0008] To achieve the above object, the present application adopts the technical scheme of a remote power supply configuration system of an ONU device, comprising:

[0009] a cloud server, configured to remotely and automatically configure a hierarchical PoE strategy table of each ONU device according to a type of terminal device connected to the ONU device;

[0010] an OLT device, configured to connect the cloud server and a photoelectric distribution socket;

[0011] the photoelectric distribution socket, configured to directly connect each ONU device through a photoelectric composite cable, serve as a photoelectric distribution device, and remotely supply power to the ONU device and the terminal device;

[0012] the ONU device, configured to connect the terminal device to a network and provide a personalized power supply scheme according to the configured hierarchical PoE strategy table.

[0013] Further, the cloud server is built-in with:

[0014] a message receiving module, configured to receive a message carrying device information sent by the ONU device;

[0015] a terminal device portrait database, configured to store historical power curves of different terminal devices and update in real time;

[0017] a strategy generating module, configured to generate a hierarchical PoE strategy table according to the received message and the terminal device portrait database, retrieve the ONU capability database, and send the hierarchical PoE strategy table to the corresponding ONU device.

[0018] Further, the ONU device is of an integrated waterproof structure, and the ports on the ONU device only include an uplink port connected to the photoelectric distribution socket and a downlink port connected to the terminal device.

[0020] S100, after the ONU device is powered on for the first time and registered, a message is sent to a cloud server; the message carries information including an ONU device MAC, a terminal device MAC, and a port-level terminal portrait field;

[0021] S200, on the cloud server side, a corresponding hierarchical PoE strategy table is generated in real time according to a terminal device portrait database and the received message, and is sent to the ONU device;

[0022] S300, at the ONU device end, the hierarchical PoE strategy table is parsed by a local daemon process, and is written into a JSON strategy file, and a PSE chip register is updated, thereby providing a personalized power supply scheme for a terminal device connected downstream.

[0023] Further, the S200 comprises the following steps:

[0024] S201, taking a terminal device MAC as an index, searching for a corresponding historical power curve in a terminal device portrait database, and determining average power consumption and peak power consumption of the terminal device;

[0025] S202, determining a maximum power value of an ONU device according to the average power consumption and the peak power consumption of the terminal device and self power consumption of the ONU device;

[0026] S203, taking an ONU device MAC as an index, searching for an ONU capability table in an ONU capability database;

[0027] S204, generating a hierarchical PoE strategy table according to the maximum power value of the ONU device and the corresponding ONU capability table, and delivering the hierarchical PoE strategy table to the ONU device;

[0028] The fields in the hierarchical PoE strategy table include a LAN port ID of the ONU device, a transmission maximum power of each LAN port, a terminal device power supply priority, a power adjustment time slot start time, a power adjustment time slot end time, a LAN port transmission maximum voltage of the ONU device, a LAN port transmission maximum current of the ONU device, and a check code; all power values in the hierarchical PoE strategy table are less than the maximum power value of the ONU device.

[0029] Further, in the S201, when no corresponding historical power curve is searched in the terminal device portrait database, a terminal device model is looked up according to the terminal device MAC and a port-level terminal portrait field, and is mapped to a corresponding typical power curve library, thereby determining the average power consumption and the peak power consumption of the terminal device.

[0030] The typical power curve library stores average power consumption, rated power, peak power, and low power consumption mode of different types of terminal devices.

[0031] Further, the S202 comprises:

[0032] The average power consumption and the peak power consumption are corrected according to an ambient temperature inside the ONU device, to obtain a corrected power;

[0033] The corrected power is aligned to 13 power levels downwardly, as the maximum power of the ONU device.

[0034] Further, the corrected power For:

[0037] Further, in the S203, the capability parameters of the ONU device are stored in the ONU capability database, and the construction method is:

[0038] At each time of online registration of the ONU device, the capability parameters of the ONU device are actively reported to the OLT device, or the capability parameters of the ONU device are acquired through the query mode issued by the OLT device;

[0039] The capability parameters of the ONU device are reported to the cloud server through the OTL;

[0040] In the cloud server, the ONU capability table of different ONU devices is formed through collection, modeling, coding and storage, and then the ONU capability database is constructed.

[0041] A computer readable storage medium stores a computer program, and the computer program is executed to realize the remote configuration method of any one of the above.

[0042] The beneficial effects of the present application are:

[0043] Zero-contact deployment: in the present application, the PoE hierarchical strategy is automatically configured remotely according to the type of terminal device and the capability parameters of the ONU device, without manually logging in the CLI of each ONU to set the PoE parameters, and flexible and personalized power supply schemes can be provided according to the differences between terminal types.

[0044] Low deployment cost: in the present application, when the equipment is laid on site, the ONU device can be directly connected with the terminal device through a shorter link, which is lower than the traditional PoE switch scheme.

[0045] Reliability: in the present application, the PoE power delivery can be dynamically adjusted according to the terminal type, which avoids excessively high or low power and ensures the stable operation of the ONU and the terminal device; by improving the waterproof performance and reducing the transmission distance of the ONU and the terminal device, the bit error rate is reduced;

[0052] The specific embodiments of the present application are described below to facilitate the understanding of the present application by those skilled in the art, but it should be clear that the present application is not limited to the scope of the specific embodiments, and for those skilled in the art, it is obvious that various changes are within the spirit and scope of the present application defined and determined by the appended claims, and all the inventions utilizing the concept of the present application are within the scope of protection.

[0053] Example 1:

[0054] The present embodiment provides a remote power supply configuration system of an ONU device to realize hierarchical configuration of PoE parameters and flexible power supply scheme.

[0055] Reference Figure 1 , the remote power supply configuration system comprises:

[0056] a cloud server, configured to remotely and automatically configure a hierarchical PoE strategy table of each ONU device according to the type of terminal device connected by the ONU device;

[0057] an OLT device, configured to connect the cloud server and the optoelectronic branching outlet;

[0058] an optoelectronic branching outlet, configured to directly connect each ONU device through an optical and electrical composite cable, serve as an optical branching device, and remotely supply power to the ONU device and the terminal device;

[0059] an ONU device, configured to connect the terminal device to the network and provide a personalized power supply scheme according to the configured hierarchical PoE strategy table.

[0060] In the embodiment, the cloud server is built-in:

[0061] The message receiving module is configured to receive a message carrying device information sent by the ONU device.

[0062] The terminal device portrait database is configured to store historical power curves of different terminal devices and update in real time.

[0063] The ONU capability database is configured to store capability parameters of the ONU device.

[0064] The policy generation module is configured to generate a hierarchical PoE policy table according to the received message and the terminal device portrait database, and retrieve the ONU capability database, and then send the hierarchical PoE policy table to the corresponding ONU device.

[0065] In the embodiment, the message receiving module actively sends a message carrying ONU device information, terminal device MAC and port-level terminal portrait field (i.e. terminal device type, including camera, sensor, etc.) after the ONU device is powered on for the first time and registered.

[0066] In the embodiment, the ONU capability database stores ONU device capability parameters, including ONU device LAN port ID, maximum transmission power of each LAN port, terminal device power supply priority, power adjustment time slot start time, power adjustment time slot end time, maximum voltage of the LAN port of the ONU device, maximum current of the LAN port of the ONU device and check code.

[0067] In the embodiment, the PoE hierarchical policy table generated includes the maximum power of the ONU device based on the ONU device capability parameters, and all power values in the ONU device capability parameters are less than the maximum power of the ONU device.

[0068] In the embodiment, the structure of the optical-electrical shunt socket is as shown in Figure 2 The structure of the ONU device is as shown in Figure 3 The optical-electrical shunt socket and the ONU device are connected through an optical-electrical composite cable, and the ONU device and the terminal device (including AP, camera and sensor, etc.) are connected through a network cable.

[0069] In the embodiment, based on the optical-electrical shunt socket port setting as shown in Figure 2 When connecting the OLT device, only one of the two OLT device connection ports needs to be connected, and a plurality of ONU devices can be connected to each ONU device connection port in FIG. 2 through an optical-electrical composite cable, and the power supply interface is arranged on the back of the device.

[0070] 1. As an optical splitter, it connects to one PON port of an OLT device uplink and multiple (e.g., 32) ONU devices downlink, so as to achieve the purpose of "passively and proportionally" splitting one optical signal into multiple paths downlink and combining multiple optical signals back into one path uplink;

[0071] 2. As an active device, it provides multiple (e.g., 32) SC / UPC fiber optic interfaces with PoF functionality to power the ONU device. In this embodiment, the traditional ONU device structure is as follows: Figure 4 As shown, its design includes essential power connection ports, terminal device connection ports, and passive optical splitter connection ports, while the design of this invention... Figure 3 In the ONU device structure shown, the ports on the ONU device only include an uplink port for connecting to the optoelectronic splitter socket and a downlink port for connecting to the terminal device. Furthermore, in a specific example of the present invention, an ONU device can be equipped with at least two types of downlink ports to meet the connection requirements of terminal devices with different interface types. Therefore, the ONU device of the present invention eliminates the power connection port found in traditional ONU devices, forming an integrated waterproof structure.

[0072] In a specific example of the present invention, a composite optical cable consisting of "single-mode glass fiber + 55V copper wire" is used between the optical fiber distribution socket in the computer room and the ONU device. The cable can simultaneously complete 1.25Gbps / 2.5Gbps data backhaul and 30W DC power supply in one deployment. Based on this, the ONU device can be placed in any position.

[0073] In a specific example of the present invention, the ONU device integrates a synchronous rectified DC-DC converter with a power conversion efficiency of ≥92%. Downlink only requires 1 to 15 meters of Category 5e twisted pair / Category 6e twisted pair cable to directly connect to the terminal, with no link attenuation and no need for a PoE switch, resulting in an overall cost reduction of ≥25%.

[0074] Furthermore, the ONU device in this invention adopts a "double-layer labyrinth + vent valve design" to form an integrated waterproof structure with a housing protection rating of IP67. The vent valve maintains a slight positive pressure of 50Pa to prevent condensation and dust intrusion. The design of combining the M12X-coded composite cable interface with silicone ensures condensation-free operation at temperatures ranging from -25℃ to 55℃ and relative humidity from 10% to 90%.

[0075] In traditional PoE networks, the connection between OLT and ONU devices is a passive "optical splitter" (also called a splitter), which only performs "downlink one-to-many / uplink many-to-one" processing on optical signals. It has no power module itself and cannot power the ONU devices, let alone the terminal devices connected to the ONU devices.

[0076] Traditional ONU devices require a separate power supply. While some ONUs support PoE to power terminal devices, most do not. Therefore, ordinary ONUs can only be placed in locations with a stable power supply, but terminal devices may be outdoors. This results in a long connection between the ONU and the terminal device, with longer connections exhibiting greater attenuation.

[0077] Based on the structural design of the aforementioned optoelectronic splitter socket and ONU device, the ONU device in this invention no longer needs a separate power supply and can simultaneously power terminal devices (such as APs, cameras, sensors, etc.) via PoE. In other words, the power source for both the ONU device and the terminal devices in this embodiment is the "optoelectronic splitter socket." Furthermore, because the ONU in this solution is waterproof, it can be placed as close as possible to the terminal devices, significantly shortening the link between the ONU and the terminal devices, and greatly reducing power consumption and signal attenuation.

[0078] Example 2:

[0079] This embodiment is a further limitation based on Embodiment 1, and its purpose is to provide a remote power supply configuration method for ONU devices. Other parts not mentioned refer to Embodiment 1 or the prior art.

[0080] refer to Figure 5 The remote power supply configuration method for ONU devices provided in this embodiment includes the following steps:

[0081] S100: After the ONU device is powered on and registered for the first time, it sends a message to the cloud server; the message carries information including the ONU device MAC, the terminal device MAC, and the port-level terminal profile field.

[0082] S200: On the cloud server side, based on the terminal device profile database and received messages, the corresponding hierarchical PoE policy table is generated in real time and sent to the ONU device.

[0083] S300, on the ONU device side, parses the hierarchical PoE policy table through the local daemon process, writes it into the JSON policy file, and updates the PSE chip register, thereby providing a personalized power supply solution for the downstream terminal devices.

[0084] In step S1, after the ONU device is powered on and registered for the first time, it actively sends a DHCPDiscover / Solicit message to the cloud server. The information carried in DHCP Option 60 / 61 includes the ONU device MAC, the terminal device MAC, and the port-level terminal profile field (the terminal profile field is the terminal device type, including cameras / sensors, etc.).

[0085] Step S200 in this embodiment includes the following sub-steps:

[0086] S201. Using the MAC address of the terminal device as an index, retrieve the corresponding historical power curve in the terminal device profile database to determine the average power consumption and peak power consumption of the terminal device.

[0087] S202. Determine the maximum power value of the ONU device based on the average power consumption and peak power consumption of the terminal device, as well as the power consumption of the ONU device itself.

[0088] S203. Using the ONU device MAC address as the index, retrieve the ONU capability table from the ONU capability database;

[0089] S204. Based on the maximum power value of the ONU device and its corresponding ONU capability table, generate a hierarchical PoE strategy table and send it to the ONU device.

[0090] The fields in the hierarchical PoE strategy table include the LAN port ID of the ONU device, the maximum transmission power of each LAN port, the power supply priority of the terminal device, the start time of the power adjustment time slot, the end time of the power adjustment time slot, the maximum transmission voltage of the LAN port of the ONU device, the maximum transmission current of the LAN port of the ONU device, and the checksum; all power values ​​in the hierarchical PoE strategy table are less than the maximum power value of the ONU device.

[0091] In step S201 of this embodiment, when no corresponding historical power curve is found in the terminal device profile database, the terminal device model is looked up in reverse according to the terminal device MAC and port-level terminal profile fields, and mapped to the corresponding typical power curve library, thereby determining the average power consumption and peak power consumption of the terminal device; wherein, the typical power curve library stores the average power consumption, rated power, peak power and low power consumption mode of different types of terminal devices.

[0092] In this embodiment, taking 1,000 terminal devices of the same model as an example, the measured power curves may differ by 5%–15% due to differences in batches, firmware versions, aging levels, and ambient temperatures. This invention eliminates individual deviations between terminal devices by searching historical power curves in the terminal device profile database.

[0093] In the embodiment, when no corresponding historical power curve is retrieved in the terminal device portrait database, the terminal device portrait database cannot be found for the first time to join the terminal device, but since the MAC address of the terminal device is the identity card number of the electronic product, the manufacturer of the terminal device can be determined through the terminal device MAC address, so that the power information of the terminal device can be queried in the typical power curve library through various means such as manual query or crawler.

[0094] The step S202 in the embodiment includes:

[0095] According to the ambient temperature inside the ONU device, the average power consumption and the peak power consumption are corrected to obtain a corrected power;

[0096] The corrected power is aligned downward to 13 power levels as the maximum power of the ONU device.

[0097] The corrected power is aligned downward to 13 power levels as the maximum power of the ONU device.

[0098]

[0099] In the formula, the first, second and third weight factors configured by the cloud server are respectively represented by The real-time return temperature value of the temperature sensor inside the ONU device is represented by The average power consumption of the device terminal in the device terminal portrait database is represented by The peak power consumption of the device terminal in the device terminal portrait database is represented by

[0100] Specifically, for the calculated corrected power, the 13 power levels (such as 4W, 7W, 15W, 30W…) specified by IEEE 802.3bt are aligned downward as the maximum power value issued by the cloud server to the ONU device.

[0101] Further, if the terminal device portrait is marked as “security camera”, the strategy of “nightly reducing code rate” is enabled by default, that is, the power is reduced by 20% during the preset time period at night, such as the period of 22:00-06:00; if the terminal device portrait is marked as “Wi-Fi7 AP”, the power is kept at full power for 24 hours, but the priority of the terminal device is set to “high priority” to ensure that the terminal device is powered preferentially when the total power supply budget is insufficient.

[0102] In step S203 of the embodiment, the capability parameters of the ONU device are stored in the ONU capability database, and the construction method is as follows:

[0103] ​​​​The ONU device actively reports the capability parameter of the ONU device to the OLT device at each time of online registration of the ONU device, or obtains the capability parameter of the ONU device through the OLT device in a query mode;

[0104] The capability parameter of the ONU device is reported to a cloud server through the OTL;

[0105] In the cloud server, an ONU capability table of different ONU devices is formed through collection, modeling, coding and storage, and an ONU capability database is constructed.

[0106] In step S204 of the embodiment, for the constructed PoE hierarchical strategy table, the cloud server sends the strategy table to the ONU device through a DHCPACK Option 43 sub-option 0x0C.

[0107] In step S300 of the embodiment, the ONU device writes the strategy table into a JSON strategy file in EEPROM immediately after the strategy table is parsed by a local daemon, and transmits the JSON strategy file to the PSE chip through an I2C bus. 2 The C / SMBus updates the PSE chip register, and subsequently, the ONU device can provide personalized power supply for the accessed terminal device according to the content of the PSE chip register.

[0108] The above remote power supply configuration method provided by the embodiment does not need manual login of CLI, and realizes automatic and flexible configuration of the power supply strategy according to the type of the terminal device connected to the ONU device.

[0109] Embodiment 3:

[0110] The embodiment is further limited on the basis of the embodiment 2, and aims to provide a storage medium for storing the implementation process of the remote power supply configuration method of the ONU device, and other parts not mentioned are referred to the embodiment 1 or the prior art.

[0111] The computer storage medium in the embodiment stores a computer program, and the computer program is executed to realize the remote power supply configuration method of any ONU device.
