Detailed description of the invention
The RRU casing provided the present invention with embodiment below in conjunction with the accompanying drawings carries out detection method and device is carried out in more detail
Ground explanation.
According to incompletely statistics, in the fault of RRU, have about 1/3rd be because poorly sealed and intake after cause setting
Standby fault, therefore, the water inlet detection of RRU is critically important, but, can only ensure with erection stage producing at present, one
Denier installation does not just have subsequent detection means, and the present invention is primarily directed to the RRU casing water inlet detection after installing.
When sealing RRU casing, the humidity in casing is absolute humidity, if in the case of casing is not intake, in casing
The relative humidity ratio of absolute humidity (humidity with) is the function of temperature, and it is the wettest that temperature severely impacts in designated space
Degree, temperature often changes 0.1 DEG C, will produce the humidity change of 0.5%RH.The embodiment of the present invention will be built when RRU casing is not intake
Vertical reaction temperature is referred to as datum curve with the curve of relative humidity corresponding relation.
The datum curve of the temperature-relative humidity of confined space is as shown in Figure 1.
Based on upper figure, following temperature-relative humidity control table can be simulated.
RRU is operated in the metal chassis of sealing, and RRU inherently works at a higher temperature (generally, in it
Portion's operating temperature is all more than 50 DEG C), if a small amount of water enters cabinet, the moisture in cabinet can evaporate, so that cabinet
Interior relative humidity increases and exceeds datum curve.
Based on above research, the embodiment of the present invention provides a kind of RRU casing water inlet detection method, as in figure 2 it is shown, include:

Line is the curve of reaction temperature and the relative humidity corresponding relation set up when RRU casing is not intake in advance.
If RRU casing is not intake, relative humidity corresponding to the temperature that gathered should just on datum curve, if
RRU casing is intake, and the relative humidity corresponding to temperature should be on datum curve, therefore, may determine that RRU by comparative result
Whether casing intakes.
The embodiment of the present invention utilizes the work characteristics of RRU high temperature, i.e. after RRU starts, temperature is the highest thus cause
Moisture evaporates, and improves water inlet detection scheme, uses the corresponding relation of temperature and humidity, and solving RRU water inlet cannot examine
The difficult problem surveyed；By RRU is carried out the most lasting monitoring, it is simple to find the potential faults of RRU water inlet, in fault generation early stage

Degree uploads to processor, and processor is that each RRU sets up data base, and this processor can be the processor on external server.
RRU common water inlet reason is that air locking is aging, seals the time that the aging needs of RRU box sealing device are longer, therefore
It is believed that casing is to seal in sealing RRU casing a period of time.Processor sets up benchmark based on data base for each RRU
Curve, specifically can use following mechanism.
Following gatherer process is performed to meeting termination condition after sealing RRU casing:
Determine with temperature sensor when collecting a design temperature, utilize humidity sensor to gather humidity, according to adopting
The humidity of collection determines that with the ratio of absolute humidity the relative humidity that this design temperature is corresponding forms original data set [F, H], wherein F
Excursion be-10～90 DEG C, H excursion is 0%～100%, preset multiple F.Because RRU is relative closure, therefore,
Also it is substantially invariable for each temperature value F, its relative humidity H.
At the end of gatherer process, for each design temperature F, mean square at all relative humiditys corresponding to this design temperature
Difference is not more than when setting thresholding, according to the meansigma methods of all relative humiditys corresponding to this design temperature, obtains this design temperature pair
The relative humidity answered；
Obtain datum curve according to the relative humidity that all design temperatures are corresponding, can be specifically to do linear smoothing to process.
Alternatively, when reaching following either condition, determine and meet termination condition:
1), when collection duration reaches to set duration, determine and meet termination condition；
For RRU casing, when RRU casing cuts out, temperature ratio is relatively low, is generally near room temperature.After RRU starts, temperature can rise
High, it will usually to rise to more than 50 degree, therefore, perform one-shot process, corresponding relative of preset temperature value can be collected
Humidity, can arrange a period according to the startup cycle of RRU, it is ensured that multiple preset temperatures are being gathered repeatedly relative humidity
Rear end gatherer process.
2) for each design temperature, collect the number of times of this design temperature reach at least n times time, determine to meet and terminate bar
Part.
After so terminating gatherer process, after each temperature value achieves minimum n times data, corresponding to each preset temperature
Relative humidity take mean square deviation and obtain [F1, H1], [F2, H2] ..., [Fn, Hn], if no more than setting thresholding, data are described
Available, the datum curve of the temperature-relative humidity of this RRU can be formed.
3) for wherein section sets temperature, collect the number of times of this design temperature reach at least n times time, determine and meet knot
Bundle condition.
I.e. there is no need by the time to gather each preset temperature and acquire at least n times data, as N-3 is preset temperature wherein
Degree collects at least n times data, it is also possible to terminate gatherer process, if some value disappearance, can do linear smoothing and process, supply
Missing data.
The embodiment of the present invention is for each temperature value, when taking mean square deviation, if this design temperature corresponding all relatively
The mean square deviation of humidity no more than sets thresholding, then take its meansigma methods as benchmark data.Alternatively, if mean square deviation is more than door
Limit, then be formed without the datum curve of the temperature-relative humidity of this RRU, it is determined that initially install for equipment poorly sealed, send alarm
Information, notifies that the upper station of attendant checks.
