Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In order to make up the deficiency of large-scale station and small-sized station monitoring system, by choosing specific one region, then be divided into multiple small grid according to topography and geomorphology and wave transmissions characteristic, arrange a radio signal transducer at each grid, transducer and central server are networked and are jointly formed gridding monitoring net.This monitoring net mainly completes the radio monitoring of urban population or social activities compact district (such as: the activities such as the wireless installation of great society of attaching most importance to activity, the examination hall monitoring of various large-scale examination provide powerful guarantee), and the monitoring finally completing seamless monitoring covering and small-signal and burst is caught.The daily use demand of systems soft ware combining wireless electricity administrative department, have employed current " software radio " design concept advanced in the world, under an open hardware platform, the function of system primarily of software definition, complete.
Systems soft ware is based on the full independent research of the API (API) that equipment is open, its function is not only better than external original-pack software (especially software module is caught in Modulation Mode Recognition software module and burst monitoring), and in aspect of performance, practicality, also take advantage in flexibility and in price.For system upgrading in the future, can when not changing hardware, a upgrade software; For the maintenance of system, not only difficulty is little, cost is low, but also can adapt to the development of radio monitoring technology in time.
Based on above-mentioned gridding monitoring system, as shown in Figure 1, Fig. 1 shows the schematic flow sheet of the gridding radio monitoring method that one embodiment of the invention provides, and the method comprises the steps:
101, according to control command, the monitoring task of system is set.
102, Real-Time Monitoring is carried out to signal, and obtain parameter and the energy historical data of described signal.
103, according to described monitoring task, judge whether described signal meets the condition preset, and if so, then catches described signal and alarm.
104, identify the kind of lock-on signal, if unidentified go out described signal, then again monitor described signal.
105, by described Signal transmissions to control centre, and according to the kind of described signal by described signal storage in a database.
In the present embodiment, step 101 specifically comprises: according to control command, arranges the monitoring task of system, and described task comprises signal capture, signal generaI investigation and data statistics.
Signal is detected, generally investigate and the know-why of data statistics as follows:
< mono->, signal monitoring principle
(1) monitoring and statistics task
A business frequency range (is seen the following form: aviation 108-137, various intercommunication 137-167 etc.) carry out loop carrier detection in a period of setting, often detect once, obtain the basic parameter of all carrier waves: bandwidth B (KHz), level P (dBm), centre frequency F (KHz), degree O (each monitoring and statistics task setting scanning times m1, if it is m1 that present scan detects number, then the degree of present scan is 100%, and this value the present invention can provide automatically).
Each scanning also may detect the carrier wave do not had in station storehouse, we are referred to as illegal carrier wave, the standard that illegal carrier wave is differentiated is: if the relative value (relative to centre frequency) measuring the F obtained is more than or equal to 0.1%, then think illegal carrier wave, if be 108.122MHz than the centre frequency of certain station carrier wave, the carrier frequency that we record is
Fm＝108.122+0.108122＝108.230122MHz
Then think that this carrier wave is illegal carrier wave.The illegal carrier wave detected can not include the statistics of degree in, this is because illegal carrier wave source has two kinds: a kind of may be owing to having used the user of this carrier wave carrier frequency tuningout, the second real illegally occupies frequency.If these two kinds of illegal carrier waves include the statistics of degree in, likely degree statistical value is greater than 100%, produces null result.The illegal carrier wave detected will be recorded in illegal carrier wave storehouse.After this monitoring task completes, add up and print illegal carrier data table reporting.
Degree is added up: see following two tables.Because the minimum statistics time is 1 hour, then doing length task time of degree statistics minimum is 1 hour, and can certainly arrange this length task time and be less than 1 hour, just degree statistics is not done in this monitoring in short-term.
Degree statistical calculation method: with the Monitoring Data of 1 hour for the minimum statistics period.
Definition:
Degree array O (m, k) (m=1,2....M, k=1,2 ... K): run-down obtains one group of degree data.Acquisition M group degree data per hour.
Variable k (k=1,2 ... K): a kth legal carrier wave of this frequency range registration in station storehouse.
Variable m (m=1,2....M): m scanning.Each minimum statistics period, this M value was generally unequal.Rule of thumb, scanning times M value per hour can not more than 10000 times.
Each hour obtains above-mentioned degree array O (m, k) as statistics source.Statistic algorithm:
The frequency range mean occupancy of each scanning:
OB (m) is the m time all arithmetic average detecting the degree of carrier wave of scanning.
The degree of each a hour kth legal carrier wave:
OF (k) is exactly the degree of a kth carrier wave of in annex 2 per hour section.
Each hour frequency range degree:
OBF is exactly each time period frequency range degree in annex 2.It is the arithmetic average of frequency range degree.
(2) task is caught in monitoring
The monitoring task of catching implements " staring " (its essence is also that energy measuring is done in receiver scanning) to a frequency range, when discovery new signal occurs, carries out the process of alarm, record, monitoring at once.
Minor alarm: obtain the frequency spectrum background information of frequency range to be scanned before the monitoring task of catching starts as ambient threshold, after task start, the new frequency spectrum obtained compares with background, if the signal occurred is greater than setting thresholding, just sends alarm and record this signal (intermediate frequency record).Recording this signal time default setting is 60 seconds.
Filtering alarm: the monitoring task of catching is the illegal carrier wave of catching in station database beyond pipe, whether so when the new carrier wave of appearance, inquire about this carrier wave is legal carrier frequency in station database, if not then alarm, if it is not alarm.
Specify alarm: in task optimum configurations, have alarm carrier frequency setting option, artificial setting n alarm frequency, and if only if there is the signal of these frequencies and meets level alarm conditions, then alarm.Alarm frequency confirms: if the value of the F of measurement acquisition and setpoint frequency error are less than 0.1%, then think that measuring the F obtained is alarm carrier frequency.
Above three kinds of alarm modes one-out-three on task interface.
Other aspect ratios of the signal of alarm frequency such as signal bandwidth, modulation type etc. need not limit.Because the parameter of software when doing energy scan be resolution bandwidth (RBW) mainly, detect number of times (single pass is to the detection number of times of a frequency), signal-noise ratio threshold.RBW is relevant with signal characteristic with scan band width, and by manually choosing RBW before doing task, it is 3K that the RBW acquiescence of energy scan program of the present invention is chosen.RBW is large, and sweep speed is fast, but likely inseparable two next-door neighbour's signals.RBW is little, and sweep speed is slow, can obtain the trickle frequency spectrum of signal.
< bis->, signal generaI investigation principle
Signal generaI investigation is exactly that setting frequency range or multiple frequency range and various signal detect condition, such as detect signal-noise ratio threshold, scanning times, RBW etc., receiver goes out all qualified signals in frequency range according to these conditional searches, radio frequency sensor process bandwidth is 20MHz, and the signal that therefore signal bandwidth is greater than 20MHz can not detect.While detecting signal, receiver provides signal degree, and the meaning of this degree is: receiver foundation is to this signal scanning number of times and the actual ratio-dependent detecting number of times of signal.
When doing signal generaI investigation, signal madulation mode is option, if selected, the present invention then does Modulation Mode Recognition to each detecting signal.The baseband signal table of the carrier wave write into Databasce detected.
Signal generaI investigation task can be set to autotask and human task pattern, and human task pattern is a kind of " flexibly " mode, and operator selects a frequency range arbitrarily on spectrogram, and just can do generaI investigation task, detecting signal is stored in baseband signal table.
< tri->, data statistics principle
The signal produced in database all comes from signal generaI investigation and signal monitoring task.Data statistics is actually to be carried out on the various signal list basis of database.Data statistics comprises: daily sheet, the moon form, degree statistics, illegal signals statistics.
It is in fact also carry out based on database data that ITU measures, and it is the result that Monitoring Data and station data produce through comparison.Monitor database had both comprised the registered legal station, also comprised the non-certificates handling station verified in monitoring.This monitor database is the set that monitoring personnel have grasped station information in detail, is also the foundation of monitor signal comparison.This signal, by monitoring investigation, after grasping the establishing platform unit, establish the information such as tableland point, radio station parameter of unknown signal, can be added monitor database by monitoring personnel.
Signal strength Computing Principle
Signal strength data convert based on signal level data to get, and the parameter that converting needs comprises the gain G A of antenna at this frequency, receiver gain GR, received signal level PR.Reduction formula is:
Software (dB μ V/m)=U λ (dB μ V)+20Logf (MHz)-G-29.8
In formula: U λ: the antenna output voltage reading dB μ V on measuring receiver input port.
For 50 Europe systems: dBm=dB μ V-107
G is antenna gain.
Citing: antenna gain is 6dB, and Received signal strength is 100MHz, and antenna output level is-50dBm, and these signal strength data are
Software (dB μ V/m)=57+40-6-29.8=61.2dB μ V/m.
According to above-mentioned principle, as shown in Figure 2, step 103, specifically comprises the steps:
If 201 monitoring tasks are signal capture, then select alarm type.
If 202 alarm types are minor alarms, then the frequency spectrum monitoring signal and the background spectra obtained in advance are compared, if described frequency spectrum is greater than described background spectra, then alarm record described signal.
If 203 alarm types are filtering alarms, then, when there is new carrier wave, judge whether described carrier wave is legal carrier wave, if not legal carrier wave, then alarm.
If 204 alarm types specify alarm, then when occurring the signal reaching default alarm frequency, then alarm.
As shown in Figure 3, step 103, also comprises the steps:
If 301 monitoring tasks are signal generaI investigation, then setting signal detects condition.
302, detect condition according to described signal, search out in frequency range all meet described in detect the signal of condition.
303, according to the scanning times of described signal and the ratio of the actual number of times detected of described signal, the degree of described signal is determined.
And to radio signal, data statistics is carried out to employing gridding monitoring net, mainly refer to: catch the result with signal generaI investigation according to above-mentioned signal monitoring, to the daily sheet to the data in database, the moon form, signal degree and illegal signals add up.
The gridding radio monitoring method that the present embodiment provides, can realize carrying out monitoring according to monitoring task to signal based on mesh wireless pyroelectric monitor system and catch, generally investigate and data statistics.
