Description
Technical field
The present invention relates to NB-IOT wireless discharging-directly station technical fields.
Background technique
NB-IOT is writing a Chinese character in simplified form for narrowband Internet of Things (Narrow BandInternetof Things), is all things on earth internet
An important branch.The characteristics of NB-IOT: 1, covering is wide, compares tradition GSM, and the area that a base station can provide 10 times covers
One base station NB-IOT of lid can cover the range of 10km, and one, small county town base station can cover.2, low-power consumption uses AA
Battery (No. 5 batteries) can work 10 years without charging.3, NB--IoT ratio LTE and the base station GPRS improve the gain of 20dB,
The place that the signals such as underground garage, basement, underground piping are difficult to reach can theoretically be covered.
The large scale deployment at present of NB-IOT network use, but in actual application from the point of view of, a large amount of underground parkings
NB-IOT jitter, or there is no signal, it needs to complete to cover using NB-IOT wireless discharging-directly station.Due to NB-IOT cell
It is all single-frequency point cell, therefore NB-IOT wireless discharging-directly station is best using frequency selection method effect.But current NB-IOT is without line selection
Frequency repeater does not have the function of automatically selecting frequency point, to need artificial setting, and when donor base station frequency point becomes
It when change, can not change, decline so as to cause the signal quality of the area of coverage in time.
Due to only one frequency point of the cell of the base station NB-IOT one, when NB-IOT wireless discharging-directly station uses NB-IOT SIM card
Donor cell frequency point can be directly read when being monitored completes frequency point setting, and when NB-IOT wireless discharging-directly station does not use NB-
When IOT SIM card, then needs to adopt and realize select frequency automatically with other methods, it is inconvenient for use.
Summary of the invention
In conclusion present invention aims at solve existing NB-IOT wireless discharging-directly station to automatically select frequency point not having
Function, the changed technical deficiency of donor base station frequency point can not be adapted to, and propose a kind of work of NB-IOT wireless discharging-directly station
Make frequency point adaptive optimization method.
To solve technical problem proposed by the invention, the technical solution of use are as follows:
The working frequency points adaptive optimization method of NB-IOT wireless discharging-directly station, it is characterised in that:
Step 1: in the factory of NB-IOT wireless discharging-directly station, input stores all of operator's planning in its monitoring system in advance
NB-IOT frequency point；
After the installation power-up of step 2:NB-IOT wireless discharging-directly station, monitoring system first carry out automatic cycle detection inputted it is all
NB-IOT frequency point downlink input signal strength, and be compared, by the strongest NB-IOT frequency point setting of the signal strength compared out
For the working frequency points of NB-IOT wireless discharging-directly station；
Step 3: according to working frequency points after the setting of NB-IOT wireless discharging-directly station, NB-IOT wireless discharging-directly station automatic adjustment equipment
Downlink gain keeps equipment down output power reasonable, and according to downlink gain adjustment uplink gain, realizes covering for uplink and downlink signals
Lid；When downlink input-output power decline dB number is more than setting value, then repeatedly above step 1~3, reselects NB-IOT frequency
Point inputs maximum NB-IOT frequency point until selecting downlink, is working frequency points by the NB-IOT frequency point setting, and resets
Downlink gain.
In step 2, if the NB-IOT frequency point signal strength of detection is below detection sensitivity, circulation inspection always
It surveys.
The invention has the benefit that being deposited since the present invention inputs in the monitoring system of NB-IOT wireless discharging-directly station in advance
All NB-IOT frequency points for storing up operator's planning, after power, by the strongest NB-IOT frequency point setting of the signal strength compared out
For the working frequency points of NB-IOT wireless discharging-directly station, or in the process of running, donor base station frequency point changes, and leads to NB-IOT frequency
Point signal strength is lower than detection sensitivity, when signal quality declines, from newly select optimal N B-IOT frequency point as working frequency points,
Have adaptive ability, save artificial setup cost, easy to use, working frequency points change is high-efficient.
Detailed description of the invention
Fig. 1 is work flow diagram of the invention；
Fig. 2 is the structural schematic diagram of NB-IOT wireless discharging-directly station of the invention.
Specific embodiment
Structure of the invention is further described below in conjunction with attached drawing and preferred embodiment of the present invention.
Shown in referring to Figures 1 and 2, the working frequency points adaptive optimization method of NB-IOT wireless discharging-directly station of the present invention:
Step 1: in the factory of NB-IOT wireless discharging-directly station, input stores all of operator's planning in its monitoring system in advance
NB-IOT frequency point.
After the installation power-up of step 2:NB-IOT wireless discharging-directly station, monitoring system first carries out what automatic cycle detection had inputted
All NB-IOT frequency point downlink input signal strengths, and be compared, specific comparison method, such as can be using successively to institute
There is NB-IOT frequency point downlink input signal strength to be compared two-by-two, chooses the stronger NB-IOT frequency of downlink input signal strength
Point, last NB-IOT frequency point that is to say the strongest NB-IOT frequency point of signal strength after comparison, and the signal compared out is strong
Spend the working frequency points that strongest NB-IOT frequency point setting is NB-IOT wireless discharging-directly station；To guarantee at NB-IOT wireless discharging-directly station
Under optimal operating mode, solves the technical deficiency of artificial selection.Due in the specific application process, under NB-IOT frequency point
Row input signal can accept it is temporary interference or other reasons lead to jitter, if only single detection or
The strongest NB-IOT frequency point of NB-IOT frequency point downlink input signal strength that multiple cycle detection compares out is carried out in short time, and
Non- is the corresponding base station NB-IOT of cell where NB-IOT wireless discharging-directly station, and will lead NB-IOT wireless discharging-directly station cannot keep
Efficient operation, the present invention thus add a detection sensitivity reference value, if the NB-IOT frequency point signal strength of detection is low
When detection sensitivity, then cycle detection always.
Step 3: according to working frequency points after the setting of NB-IOT wireless discharging-directly station, NB-IOT wireless discharging-directly station adjust automatically is set
Standby downlink gain, keeps equipment down output power reasonable, and according to downlink gain adjustment uplink gain, realizes uplink and downlink signals
Covering；Equipment down output power rationally refers at the equipment after NB-IOT wireless discharging-directly station chooses matched working frequency points
Within the scope of normal output power.When downlink input-output power decline dB number be more than setting value when, then repeatedly above step 1~
3, NB-IOT frequency point is reselected, maximum NB-IOT frequency point is inputted until selecting downlink, is work by the NB-IOT frequency point setting
Make frequency point, and resets uplink and downlink gain.This step mainly solves in the process of running, and donor base station frequency point becomes
Change, cause NB-IOT frequency point signal strength lower than detection sensitivity, the technical issues of signal quality declines, the present invention can be from new
Select optimal N B-IOT frequency point as working frequency points, have adaptive ability, save artificial setup cost, easy to use, work
It is high-efficient to make frequency point change.
