In this embodiment, a wireless connection is established between the terminal and the optical fiber distribution system, and as an implementation manner, in this embodiment, the terminal and the optical fiber distribution system are both provided with a Wi-Fi module, and when the terminal establishes a Wi-Fi connection with the optical fiber distribution system, the terminal searches for an SSID (Service Set Identifier) and searches for a corresponding name of the optical fiber distribution system, so as to establish the wireless connection and facilitate identification and operation by an engineer.
Step S200, detecting the signal intensity of the received base station radio frequency coupling signal, and adjusting the coupling degree between the base station feeder line and the optical fiber distribution system according to the detected signal intensity.
The optical fiber distribution system detects the signal intensity of a base station radio frequency coupling signal issued by a base station and adjusts the coupling degree between a base station feeder line and the optical fiber distribution system according to the detected signal intensity; specifically, a signal strength threshold is set, for example, a signal strength threshold of-30 dBm; if the signal intensity of the base station radio frequency coupling signal is greater than the signal intensity threshold value, the base station state is represented to be normal, and the signal intensity of the base station radio frequency coupling signal received by the optical fiber distribution system meets the station opening requirement; if the signal intensity of the base station radio frequency coupling signal is not greater than the signal intensity threshold value, which represents that the base station is not started or the base station is abnormal, the coupling degree between the base station feeder line and the optical fiber distribution system is adjusted to improve the signal intensity of the base station radio frequency coupling signal, so that the adjusted signal intensity is greater than the signal intensity threshold value, and the station opening requirement of the optical fiber distribution system is met.
In this embodiment, adjusting the coupling degree between the base station feeder line and the optical fiber distribution system may be implemented by adjusting a coupler or an attenuator between the base station feeder line and the optical fiber distribution system.

The operator sets a network management center, i.e. a network management node, for each area, such as each city or province, to manage the accessed wireless communication devices. Each network management center is configured with a number for receiving the reporting parameters of the access equipment. Based on the number of the current network management center, the optical fiber distribution system reports the identifier of the optical fiber distribution system to the network management center, wherein the identifier can be the SIM card number of the optical fiber distribution system.
In the embodiment, the station opening instruction sent by the terminal is received; the open station instruction is used for indicating the optical fiber distribution system to start open station; detecting the signal intensity of a received base station radio frequency coupling signal, and adjusting the coupling degree between a base station feeder line and an optical fiber distribution system according to the detected signal intensity; determining a working channel frequency point of an optical fiber distribution system; acquiring the longest optical fiber link time delay, and setting the longest optical fiber link time delay as a time delay parameter of an optical fiber distribution system; reporting network management parameters to a network management node to complete the station opening, wherein the network management parameters comprise the identification of the optical fiber distribution system; therefore, the station opening instruction sent by the terminal triggers the optical fiber distribution system to start station opening, and the optical fiber distribution system completes automatic station opening of the optical fiber distribution system by adjusting the coupling degree between the base station feeder line and the optical fiber distribution system, determining the frequency point of a working channel, setting a time delay parameter and reporting a network management parameter to a network management node; the problems of long station opening period and low station opening efficiency of the optical fiber distribution system caused by the fact that an engineer opens the station of the optical fiber distribution system manually in the traditional technology are solved. The embodiment realizes the automatic station opening of the optical fiber distribution system, shortens the station opening period of the optical fiber distribution system, improves the station opening efficiency and reduces the station opening cost.
In another embodiment, based on the embodiment shown in fig. 2, referring to fig. 3, in the method for opening a fiber distribution system in this embodiment, step S200 specifically includes:
step S210, obtaining the input power of the base station rf coupling signal.
In this embodiment, the input power of the base station rf coupling signal is specifically used to correspondingly characterize the signal strength of the base station rf coupling signal, and the greater the input power of the base station rf coupling signal, the greater the corresponding signal strength of the base station rf coupling signal.
The optical fiber distribution system acquires the input power of the base station radio frequency coupling signal.
Step S220, detecting whether the input power is greater than a first threshold.
And detecting whether the input power of the base station radio frequency coupling signal is greater than a set first threshold value, wherein the base station radio frequency coupling signal is obtained by shunting a wireless signal of the base station to an optical fiber distribution system, and if the input power is too small, the base station is not started or the base station is abnormal.
Step S230, if the input power is not greater than the first threshold, adjusting a coupling degree between the base station feeder and the optical fiber distribution system so that the input power is greater than the first threshold.
If the optical fiber distribution system detects that the input power is not greater than the first threshold, the coupling degree of the coupler between the base station feeder and the optical fiber distribution system is adjusted until the input power of the radio frequency coupling signal is greater than the first threshold, and the first threshold may be set according to an actual situation in implementation, which is not limited herein.
Therefore, whether the input power is greater than a first threshold value or not is detected by acquiring the input power of the radio frequency coupling signal of the base station, and if the input power is not greater than the first threshold value, the coupling degree between the feeder line of the base station and the optical fiber distribution system is adjusted to enable the input power to be greater than the first threshold value; the base station state is ensured to be normal, the base station radio frequency coupling signal input into the optical fiber distribution system meets the station opening condition, the optical fiber distribution system can automatically open the station, and the station opening efficiency is improved.
Fig. 4 is a flowchart illustrating a method for opening a fiber distribution system according to another embodiment. On the basis of the embodiment shown in fig. 2, step S300 includes S310, S320, and S330:
step S310, acquiring the working frequency band of the optical fiber distribution system.
The optical fiber distribution system acquires a corresponding working frequency band, specifically, a downlink working frequency band of the optical fiber distribution system.
According to the network building requirement and the analysis of network evolution, an operator defines the bandwidth, the uplink working frequency band and the downlink working frequency band corresponding to the optical fiber distribution system under different network modes by considering the characteristics of flexible structure, convenient expansion and the like of the optical fiber distribution system.
Step S320, from the initial frequency point of the working frequency band, the base station synchronization frequency point is detected in the working frequency band at the preset frequency point interval.
The optical fiber distribution system detects a base station synchronization frequency point in a working frequency band at preset frequency point intervals from an initial frequency point of a downlink working frequency band, wherein the base station synchronization frequency point is a frequency point which is synchronous with a synchronization signal of a base station and has the maximum synchronization power in a base station radio frequency coupling signal, and it needs to be noted that the detected base station synchronization frequency point is also a central frequency point of the base station radio frequency coupling signal.
As an implementation manner, referring to fig. 5, fig. 5 is a schematic diagram of a refining step in step S320 in this embodiment, where step S320 in this embodiment may specifically include the following refining step:
step S321, obtaining the working bandwidth of the optical fiber distribution system.
The optical fiber distribution system obtains the current network system, and the downlink working frequency band and the working bandwidth corresponding to the optical fiber distribution system under the network system.
Step S322, based on the initial frequency point of the working frequency band, obtaining the PSS value of the synchronous signal receiving power corresponding to the base station radio frequency coupling signal in the working bandwidth at the preset frequency point interval, and obtaining the PSS value corresponding to each frequency point.
In this embodiment, specifically, the optical fiber distribution system scans the PSS value of the base station rf coupling signal corresponding to each frequency sweep point in the working bandwidth at preset frequency point intervals by using the start frequency point of the working frequency band as the frequency sweep start point. The optical fiber distribution system acquires the PSS value of the base station radio frequency coupling signal at each scanning frequency point. Specifically, each sweep frequency point is stepped at preset frequency point intervals with the starting frequency point of the working frequency band as a starting point.
In this embodiment, the frequency of the central frequency point of the base station radio frequency coupling signal is an integral multiple of 100KHz, so in order to scan the PSS value of the central frequency point, the preset frequency point interval is set to 100 KHz; namely, the optical fiber distribution system takes the starting frequency point of the working frequency band as the frequency sweep starting point, and steps by 100khz to obtain the PSS value corresponding to each frequency sweep point of the base station radio frequency coupling signal in the working bandwidth.
And step S323, taking the frequency point with the maximum PSS value as the base station synchronization frequency point.
PSS (Primary Synchronization Signal) is a correlation between the UE in the LTE network and the received Signal by using a known Synchronization sequence, and finds the maximum correlation peak, thereby obtaining the Primary Synchronization sequence and the Primary Synchronization channel position of the cell, and achieving OFDM symbol Synchronization.
In this embodiment, the PSS value of each scanning frequency point corresponding to the base station rf coupling signal is used to represent the signal strength of the base station rf coupling signal at the frequency point.
The optical fiber distribution system takes the frequency point with the maximum PSS value as a base station synchronization frequency point, namely a central frequency point of a base station radio frequency coupling signal.
And step S330, setting the detected synchronous frequency point of the base station as the working channel frequency point of the optical fiber distribution system.
Further, 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.
In the embodiment, a base station synchronization frequency point is detected in a working frequency band at a preset frequency point interval from an initial frequency point of the working frequency band by acquiring the working frequency band of the optical fiber distribution system, and the detected base station synchronization frequency point is set as a working channel frequency point of the optical fiber distribution system; the method comprises the steps that the acquisition process of base station synchronous frequency points can be to acquire the working bandwidth of an optical fiber distribution system, and based on the initial frequency point of a working frequency band, the PSS value of the synchronous signal receiving power corresponding to the base station radio frequency coupling signal in the working bandwidth is acquired at preset frequency point intervals to obtain the PSS value corresponding to each frequency point, and the frequency point with the maximum PSS value is taken as the base station synchronous frequency point; therefore, the optical fiber distribution system automatically completes the setting of the working channel frequency point by scanning the base station synchronous frequency point of the base station radio frequency coupling signal according to the synchronous signal of the base station, manual intervention is not needed, and the station opening efficiency is improved.
In another embodiment, based on the embodiment shown in fig. 5, in this embodiment, referring to fig. 6, after step S322, the method further includes:
in step S324, it is detected whether the maximum PSS value of the PSS values is greater than a preset synchronization power threshold.
If the maximum PSS value is greater than the synchronization power threshold, step S323 is performed.
Specifically, if it is detected that the maximum PSS value is lower than the synchronization power threshold value in the base station rf coupled signal, it indicates that the base station has no synchronization signal in the current operating frequency band.
In this embodiment, if it is detected that the maximum PSS value of the PSS values is greater than the synchronization power threshold value, it indicates that the base station has a synchronization signal in the current operating frequency band, and the state of the base station is normal, the step of taking the frequency point with the maximum PSS value as the base station synchronization frequency point is further performed to determine the operating channel frequency point of the optical fiber distribution system; thereby ensuring the open-site accuracy of the optical fiber distribution system.
Further, in another embodiment, on the basis of the embodiment shown in fig. 6, after step S324, the method for opening a fiber distribution system in this embodiment further includes the steps of:
and if the maximum PSS value is not larger than the synchronous power threshold value, accumulating one frequency sweep failure time, and detecting whether the accumulated frequency sweep failure time exceeds a second threshold value.
And if the accumulated frequency sweep failure times do not exceed a second threshold value, executing an initial frequency point based on a working frequency band, and acquiring a synchronous signal receiving power PSS value corresponding to a base station radio frequency coupling signal in a working bandwidth at a preset frequency point interval to obtain a PSS value corresponding to each frequency point. Namely, if the accumulated frequency sweep failure times do not exceed the second threshold value, the optical fiber distribution system continues to start frequency sweep so as to determine the working channel frequency point of the optical fiber part system.
If the accumulated frequency sweep failure times exceed a second threshold value, the current process is ended, prompt information is sent to the terminal, and the base station is prompted to be started temporarily and failed to start.
The second threshold may be set by itself in actual implementation, for example, if the second threshold is set to three times, the optical fiber distribution system starts a frequency sweeping process at most three times, and if the maximum PSS value of the base station radio frequency coupling signal is not greater than the synchronization power threshold value in the three frequency sweeps, that is, all the three frequency sweeps determine the working channel frequency point of the optical fiber distribution system, the base station is prompted to be temporarily not enabled, and the station opening fails.
In this embodiment, by setting the second threshold, the problem of channel resource waste caused by the continuous frequency sweep search of the working channel frequency point by the optical fiber distribution system when the base station is not enabled is avoided.
Fig. 7 is a flowchart illustrating a method for opening a fiber distribution system according to another embodiment. On the basis of the embodiment shown in fig. 4, the method for opening the optical fiber distribution system in this embodiment further includes:
step S610, obtain the maximum synchronization power value of the optical fiber distribution system.
The optical fiber distribution system acquires a maximum synchronization power value of the system, which is a set desired output power of the optical fiber distribution system, i.e., a target power.
In this embodiment, the fiber distribution system obtains the target power, and the purpose is to adjust the device gain amount of the fiber distribution system, so that the fiber distribution system outputs the power equal to or closest to the target power.
Step S620, comparing the maximum PSS value of the PSS values with the maximum synchronization power value, and adjusting the device gain of the optical fiber distribution system according to the comparison result.
Comparing the power value of the base station radio frequency coupling signal with the maximum synchronous power value; specifically, the power value of the base station rf coupling signal is represented by the power value of the center frequency point of the base station rf coupling signal, that is, the power value of the base station rf coupling signal is the maximum PSS value among the PSS values of the scanning frequency points in the base station rf coupling signal.
And the optical fiber distribution system compares the maximum PSS value with the maximum synchronous power value and adjusts the equipment gain of the optical fiber distribution system according to the comparison result.
As an implementation manner, referring to fig. 8, fig. 8 is a schematic diagram of a refinement step of step S620, and step S620 includes:
step S621, if the maximum PSS value is greater than the error upper limit of the maximum synchronization power value, sending a compression gain prompt to the terminal.
In this embodiment, the maximum synchronization power value has an upper error limit and a lower error limit within an allowable error range, for example, the upper error limit is +5db, and the lower error limit is-5 db.
If the maximum PSS value is larger than the error upper limit value of the maximum synchronous power value, sending a compression gain prompt to the terminal; that is, if the maximum PSS value of the base station rf coupled signal exceeds the allowable error range and is higher than the upper error limit, the optical fiber distribution system sends a compression gain prompt to the terminal, which prompts the engineer to increase the coupling degree of the coupler to compress the gain, so as to reduce the maximum PSS value of the base station rf coupled signal, and output the maximum PSS value until the adjusted maximum PSS value reaches the allowable error range of the maximum synchronization power value.
In step S622, if the maximum PSS value is smaller than the error lower limit of the maximum synchronization power value, an amplification gain prompt is sent to the terminal.
If the maximum PSS value is smaller than the error lower limit value of the maximum synchronous power value, an amplification gain prompt is sent to the terminal; that is, if the maximum PSS value of the base station rf coupled signal exceeds the allowable error range and is lower than the lower error limit, the optical fiber distribution system sends an amplification gain prompt to the terminal, which prompts the engineer to reduce the coupling degree of the coupler to amplify the gain, so as to improve the maximum PSS value of the base station rf coupled signal, and output the maximum PSS value until the adjusted maximum PSS value reaches the allowable error range of the maximum synchronization power value.
Step S623, if the maximum PSS value is greater than the maximum synchronization power value and smaller than the error upper limit, the base station rf coupled signal is attenuated, so that the maximum PSS value of the base station rf coupled signal in each frequency point is equal to the maximum synchronization power value.
If the maximum PSS value of the base station radio frequency coupling signal is between the maximum synchronous power value and the error upper limit value, the attenuator is adjusted so that the maximum PSS value is equal to the maximum synchronous power value and then output.
As an embodiment, if the maximum PSS value is greater than the error lower limit and less than the maximum synchronization power value, the base station coupling signal is not adjusted.
In this embodiment, by adjusting the output power of the radio frequency coupling signal of the base station in the above manner, it is ensured that the optical fiber distribution system outputs at the optimal power, and the station opening effect is ensured. According to the method and the device, professional engineers do not need to be arranged to conduct complex power debugging for opening the station, the efficiency of opening the station is improved, and the difficulty of opening the station is reduced.
In another embodiment, based on the embodiment shown in fig. 2, referring to fig. 9, fig. 9 is a schematic diagram of a refinement step of step S400 in this embodiment, where step S400 in this embodiment specifically includes:

Step S420, obtain a first longest response time of the response times of the plurality of extension units, and adjust the time delay of each extension unit to the first longest response time.
The response time of the extension unit is the time consumed by the extension unit to receive the target data, the response time of each extension unit is unequal, the optical fiber distribution system selects the first longest response time which consumes the longest time from the multiple response times, and the time delay of each extension unit is adjusted to the first longest response time, so that the time delay of each extension unit is ensured to be consistent.
Step S430, obtain the second longest response time of the response times of the remote units, and adjust the time delay of each remote unit to the second longest response time.
The response time of the remote units is the time consumed by the remote units for receiving the target data, the response time of each remote unit is unequal, the optical fiber distribution system selects the second longest response time which consumes the longest time from the multiple response times, and the time delay of each remote unit is adjusted to the second longest response time, so that the time delay of each remote unit is ensured to be consistent.
By the above method, the time delay of each extension unit and each remote unit in the optical fiber distribution system is consistent, and the accuracy of the optical fiber distribution system for transmitting the base station radio frequency coupling signal is ensured.
As an implementation manner, this embodiment further includes the steps of:
and numbering each extension unit and each remote unit respectively according to a preset numbering rule, and reporting the numbering result to the network management node.
The optical fiber distribution system numbers the extension units and the remote units respectively according to the numbering rules, sets unique codes for each extension unit and each remote unit, and reports the numbering result to the network management node, so that the network management node can register and manage all accessed devices, and therefore the problems of high labor cost and low numbering efficiency caused by the fact that engineering personnel coordinate property to enter a machine room and then manually number the devices are solved.

step S720, configuring the uplink and downlink matching information and the special subframe matching information of the optical fiber distribution system.
In a mobile communication system of a time division duplex system, different time slots using the same frequency carrier are used as bearers of a channel for reception and transmission, and time resources are allocated in uplink and downlink directions. In a certain time period, the base station sends signals to the optical fiber distribution system, and the optical fiber distribution system sends signals to the base station in the middle time gap, so that the base station and the optical fiber distribution system can work smoothly only by coordination and consistency.
Therefore, if the current working mode is the tdd mode, the optical fiber distribution system first configures uplink and downlink matching information and special subframe matching information, and then performs step S300.
If the working mode is the frequency division duplex mode, the step S300 is directly executed.
In the embodiment, the current working mode of the optical fiber distribution system is detected to be a frequency division duplex mode or a time division duplex mode, and different implementation modes are provided under different working modes, so that the application scene of the application is expanded.
