In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.

The embodiment of the application provides a method, a device, electronic equipment and a storage medium for opening an optical fiber distribution system, which aim to solve the technical problems of long opening period and low opening efficiency of the optical fiber distribution system caused by manual opening of the optical fiber distribution system by engineering personnel in the traditional technology. The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail by examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

The method for opening the optical fiber distribution system provided by the application can be applied to an application environment shown in fig. 1, in particular to an optical fiber distribution system 100 shown in fig. 1, wherein the optical fiber distribution system 100 comprises an access unit 20, a plurality of extension units 30, a plurality of remote units 40 and a main control unit 50.

It should be noted that, in the method for opening a fiber distribution system according to the embodiment of the present application, the execution body may be the main control unit 50 in the fiber distribution system, and the main control unit in the fiber distribution system may implement the method for opening a fiber distribution system in a manner of software, hardware or a combination of software and hardware. In the following method embodiments, the implementation subject is an optical fiber distribution system as an example.

Referring to fig. 2, a flowchart of a method for opening a fiber distribution system according to an embodiment of the present application is shown, where as shown in fig. 2, the method for opening a fiber distribution system may include the following steps:

And S10, after the main control unit detects that the optical fiber distribution system is electrified, acquiring the signal intensity of the radio frequency coupling signal received by the access unit.

The power-on of the optical fiber distribution system refers to the power-on of an access unit, a plurality of expansion units, a plurality of remote units and a main control unit in the optical fiber distribution system. When the optical fiber distribution system needs to be started, the access unit, the plurality of expansion units, the plurality of remote units and the main control unit in the optical fiber distribution system are all electrified, and at the moment, the optical fiber distribution system enters a start-up flow, and the specific start-up flow is shown in the following steps.

In this embodiment, the power-on of the optical fiber distribution system may enable the access unit, the plurality of expansion units, and the plurality of remote units in the optical fiber distribution system to be powered on by the control terminal sending the control signal, and in addition, the power grid may be directly accessed when the access unit, the plurality of expansion units, and the plurality of remote units are arranged, so that the power-on of each unit is realized.

And S20, when the main control unit detects that the signal intensity meets a preset intensity threshold, determining a working channel frequency point of the optical fiber distribution system.

The method comprises the steps that a main control unit in the optical fiber distribution system detects the signal intensity of a radio frequency coupling signal sent by a base station or a remote radio unit (Remote Radio Unit, RRU), and according to the detected signal intensity of the radio frequency coupling signal, when the signal intensity of the radio frequency coupling signal meets a preset intensity threshold, the optical fiber distribution system meets the start-up requirement, specifically, the preset intensity threshold can be set to be minus 30dBm, if the main control unit detects that the signal intensity of the radio frequency coupling signal is greater than or equal to the preset intensity threshold, the state of the base station is normal, and the signal intensity of the radio frequency coupling signal received by the optical fiber distribution system meets the start-up requirement; if the main control unit detects that the signal intensity of the radio frequency coupling signal is smaller than the preset intensity threshold, the main control unit indicates that the base station is not started or the base station is abnormal, and the start-up requirement of the optical fiber distribution system is not met.

The downlink synchronization signals in the optical fiber distribution system are divided into a main synchronization signal (Primary Synchronization Signal, PSS) and an auxiliary synchronization signal (Secondary Synchronization Signal, SSS), and the advantages of adopting the main synchronization signal and the auxiliary synchronization signal are that the main control unit of the optical fiber distribution system can be ensured to accurately and rapidly detect the main synchronization signal, and the auxiliary synchronization signal is detected on the premise of the known main synchronization signal, so that the cell search process is accelerated. Therefore, when the main control unit detects that the signal strength of the radio frequency coupling signal sent by the base station or the remote radio unit meets the preset strength threshold, the working channel frequency point of the optical fiber distribution system needs to be determined first. Specifically, the working channel refers to a transmission channel used when the optical fiber distribution system works, a main control unit in the optical fiber distribution system searches a central frequency point of a radio frequency coupling signal sent by a base station or a remote radio unit, and the found central frequency point of the radio frequency coupling signal is set as the working channel frequency point of the optical fiber distribution system.

In this embodiment, as an implementation manner, the determining the center frequency point of the radio frequency coupling signal may be calculating the synchronous power of each frequency point in the radio frequency coupling signal, taking the frequency point with the largest synchronous power as the center frequency point of the radio frequency coupling signal of the base station, and further setting the center frequency point as the frequency point of the working channel of the optical fiber distribution system.

In other embodiments, the frequency point of the working channel of the optical fiber distribution system is determined, or the frequency point used when the optical fiber distribution system works before is stored in the optical fiber distribution system, and the optical fiber distribution system does not need to determine the frequency point of the working channel by searching the central frequency point of the radio frequency coupling signal, but can directly set the stored frequency point as the current frequency point of the working channel.

S30, the main control unit determines the type of the working system of the optical fiber distribution system according to the frequency point of the working channel.

The types of operation modes of the optical fiber distribution system include frequency division duplex mode and time division duplex mode, wherein frequency division duplex (Frequency Division Duplex, FDD), also called full duplex, requires two independent channels for operation, one channel for transmitting information downward and the other channel for transmitting information upward. A guard band exists between the two channels to prevent mutual interference between adjacent transmitters and receivers. Time division duplexing (Time Division Dual, TDD), also known as half-duplexing, requires only one channel. This same channel is used for both downward and upward transmissions because the transmitter and receiver do not operate simultaneously and interference between them is not possible. After the working channel frequency point of the optical fiber distribution system is determined, the type of the working system of the optical fiber distribution system can be determined according to the frequency range of the working channel frequency point of the optical fiber distribution system.

The method for starting the optical fiber distribution system disclosed by the embodiment meets different frequency division duplex systems and time division duplex systems, and different embodiments are given under different working systems, so that the application scene of the application is enlarged.

Specifically, if the frequency point of the working channel is located in the first preset frequency range, the type of the working system of the optical fiber distribution system is a frequency division duplex system, and if the frequency point of the working channel is located in the second preset frequency range, the type of the working system of the optical fiber distribution system is a time division duplex system. When the operation mode type of the optical fiber distribution system is determined to be a time division duplex mode, the method further comprises the following steps:

And setting up and down proportioning information and special subframe proportioning information of the optical fiber distribution system.

In a mobile communication system of a time division duplex system, time resources are allocated in uplink and downlink directions by receiving and transmitting carriers using different slots of the same frequency carrier as channels. In a certain time period, the base station or the remote radio unit transmits radio frequency coupling signals to the optical fiber distribution system, and the optical fiber distribution system transmits signals to the base station or the remote radio unit in the middle time interval, so that the base station or the remote radio unit and the optical fiber distribution system can work smoothly under the coordination and the consistency. Therefore, if the current working system is a time division duplex system, the main control unit in the optical fiber distribution system firstly sets up the uplink and downlink proportioning information and the special subframe proportioning information, and then adjusts the gain parameters of the optical fiber distribution system according to the signal intensity.

And S40, the main control unit adjusts gain parameters of the optical fiber distribution system according to the signal intensity.

In this embodiment, after the optical fiber distribution system obtains the signal strength of the radio frequency coupling signal sent by the base station or the remote radio unit, the main control unit adjusts the gain parameter of the optical fiber distribution system according to the signal strength, so that the optical fiber distribution system outputs power equal to or closest to the target power.

The signal strength of the radio frequency coupling signal sent by the base station or the radio frequency remote unit comprises the transmitting power of the radio frequency coupling signal transmitted by the base station or the radio frequency remote unit, and the power value of the radio frequency coupling signal sent by the base station or the radio frequency remote unit is compared with the maximum synchronous power value. Specifically, the power value of the radio frequency coupling signal issued by the base station is represented by the power value of the center frequency point of the radio frequency coupling signal, that is, the power value of the radio frequency coupling signal is the maximum main synchronization signal receiving power value in the main synchronization signal receiving power values of all the scanning frequency points in the radio frequency coupling signal. And the optical fiber distribution system compares the maximum main synchronous signal receiving power value with the maximum synchronous power value, and adjusts the gain parameter of the optical fiber distribution system according to the comparison result.

S50, the main control unit determines the time delay parameter of the optical fiber distribution system.

Because the optical fiber distribution system comprises an access unit, a plurality of expansion units and a plurality of remote units, each expansion unit is respectively in communication connection with the access unit, and the access unit transmits a data packet to each expansion unit and transmits the data packet to each remote unit through each expansion unit. Because the time consumption of receiving the data packets sent by the access units by different extension units is different, the time consumption of receiving the data packets sent by the extension units by different remote units is different, and therefore, the time delay of sending the data packets of a plurality of optical fiber links formed by different extension units and the remote units is different. The main control unit is used for determining the time delay parameter of the optical fiber distribution system, so that the time delay consistency of data packets sent by all optical fiber links in the optical fiber distribution system can be ensured.

S60, the main control unit controls the access unit to send the radio frequency coupling signal to the remote unit through the expansion unit based on the working mode type, the gain parameter and the time delay parameter.

When the main control unit determines the working system type of the optical fiber distribution system, the gain parameters of the optical fiber distribution system are adjusted and adjusted according to the determined gain parameters, so that the optical fiber distribution system outputs with optimal power, the access unit sends the radio frequency coupling signals to the remote units with the same time delay parameters through the working system type, and at the moment, the time delay parameters of the radio frequency coupling signals received by the remote units are the same.

According to the method for starting the optical fiber distribution system, after the main control unit detects that the optical fiber distribution system is electrified, the signal intensity of the radio frequency coupling signal transmitted by the base station and received by the access unit is obtained; when the main control unit detects that the signal intensity meets a preset intensity threshold value, determining a working channel frequency point of the optical fiber distribution system; the main control unit determines the type of the working system of the optical fiber distribution system according to the frequency point of the working channel; the main control unit adjusts gain parameters of the optical fiber distribution system according to the signal intensity; the main control unit determines the time delay parameter of the optical fiber distribution system; the main control unit controls the access unit to send the radio frequency coupling signal to the remote unit through the expansion unit based on the working mode type, the gain parameter and the time delay parameter. Therefore, the optical fiber distribution system can be triggered to start after the optical fiber distribution system is electrified, and after the optical fiber distribution system determines the frequency point and the type of the working system, adjusts the gain parameters and sets the time delay parameters, the control access unit sends the radio frequency coupling signals to the remote unit through the expansion unit to finish the automatic start of the optical fiber distribution system, so that the problems of long start period and low start efficiency of the optical fiber distribution system caused by the fact that engineering personnel manually start the optical fiber distribution system in the prior art are avoided. According to the embodiment, the automatic start-up of the optical fiber distribution system is realized, the automatic start-up is realized, the start-up period of the optical fiber distribution system is shortened, the start-up efficiency is improved, and the start-up cost is reduced.

S22, the main control unit detects the synchronous frequency point of the base station in the working frequency band from the initial frequency point of the working frequency band at preset frequency point intervals.

The main control unit of the optical fiber distribution system detects base station synchronization frequency points in the working frequency band from the initial frequency point of the downlink working frequency band at preset frequency point intervals, wherein the base station synchronization frequency points refer to frequency points with the largest synchronization power and with the synchronization signals of the base stations in the radio frequency coupling signals, and the detected base station synchronization frequency points are the center frequency points of the radio frequency coupling signals.

In this embodiment, specifically, the main control unit in the optical fiber distribution system uses the starting frequency point of the working frequency band as the sweep frequency starting point, scans the working bandwidth at preset frequency point intervals, and receives the power value of the main synchronization signal corresponding to each sweep frequency point by using the radio frequency coupling signal. A main control unit in the optical fiber distribution system acquires the main synchronous signal receiving power values of the radio frequency coupling signals at all sweep points. Specifically, each sweep frequency point takes a starting frequency point of a working frequency band as a starting point and steps at preset frequency intervals.

In this embodiment, the frequency of the center frequency point of the rf coupling signal is an integer multiple of 100KHz, so, in order to scan the primary synchronization signal receiving power value of the center frequency point, the preset frequency is set to 100KHz; the main control unit in the optical fiber distribution system takes the initial frequency point of the working frequency band as a sweep frequency starting point, steps by 100khz, and obtains the main synchronous signal receiving power value corresponding to the radio frequency coupling signal at each sweep frequency point in the working bandwidth.

The main control unit takes the frequency point with the maximum main synchronous signal receiving power value as the base station synchronous frequency point.

The PSS (Primary Synchronization Signal ), which is a correlation between a UE in an LTE network and a received signal by using a known synchronization sequence, finds the maximum correlation peak, thereby obtaining the primary synchronization sequence and the primary synchronization channel position of the cell, and achieving OFDM (Orthogonal Frequency Division Multiplexing ) symbol synchronization.

In this embodiment, the main control unit adopts the main synchronization signal receiving power values of each sweep frequency point corresponding to the radio frequency coupling signal, and characterizes the signal strength of the radio frequency coupling signal at the frequency point. The main control unit of the optical fiber distribution system takes the frequency point with the maximum main synchronous signal receiving power value as the base station synchronous frequency point, namely the central frequency point of the radio frequency coupling signal.

S23, the main control unit sets the detected base station synchronous frequency point as a working channel frequency point of the optical fiber distribution system.

Further, the main control unit of the optical fiber distribution system sets the detected base station synchronization frequency point as a working channel frequency point of the optical fiber distribution system.

According to the embodiment, the master control unit acquires the working frequency band of the optical fiber distribution system, detects base station synchronous frequency points in the working frequency band at preset frequency point intervals from the initial frequency point of the working frequency band, and sets the detected base station synchronous frequency points as working channel frequency points of the optical fiber distribution system; the process of obtaining the base station synchronization frequency points can be to obtain the working bandwidth of the optical fiber distribution system, obtain the main synchronization signal receiving power value of the synchronization signal receiving power corresponding to the radio frequency coupling signal in the working bandwidth at preset frequency point intervals based on the initial frequency point of the working frequency band, obtain the main synchronization signal receiving power value corresponding to each frequency point, and take the frequency point with the maximum main synchronization signal receiving power value as the base station synchronization frequency point; therefore, the optical fiber distribution system automatically completes the setting of the frequency point of the working channel by scanning the base station synchronous frequency point of the radio frequency coupling signal according to the synchronous signal of the base station, does not need manual intervention, and improves the station opening efficiency.

S42, the main control unit compares the maximum main synchronous signal receiving power value with the maximum synchronous power value in the main synchronous signal receiving power values, and adjusts the gain parameters of the optical fiber distribution system according to the comparison result.

The main control unit compares the power value of the radio frequency coupling signal with the maximum synchronous power value; specifically, the power value of the rf coupling signal is represented by the power value of the center frequency point of the rf coupling signal, that is, the power value of the rf coupling signal is the maximum primary synchronization signal receiving power value among the primary synchronization signal receiving power values of all the sweep points in the rf coupling signal.
