Embodiment
Below in conjunction with drawings and Examples, RRU casing provided by the invention is carried out to detection method and device illustrates in greater detail.
According to incompletely statistics, in the fault of RRU, there are 1/3rd left and right to be because cause equipment failure after poorly sealed and water inlet, therefore, it is very important that the water inlet of RRU detects, and still, can only guarantee in production and installation phase at present, once installation has not just had subsequent detection means, the present invention detects for the RRU casing water inlet after installing.
Humidity when sealing RRU casing in casing is absolute humidity, if in the situation that casing is not intake, relative humidity (ratio of humidity and absolute humidity) in casing is the function of temperature, temperature seriously affects the relative humidity in designated space, 0.1 ℃ of the every variation of temperature, changes the humidity that produces 0.5%RH.The temperature of reaction of setting up in the time that RRU casing is not intake and the curve of relative humidity corresponding relation are called datum curve by the embodiment of the present invention.
The datum curve of the temperature-relative humidity of confined space as shown in Figure 1.
Based on upper figure, can simulate temperature-relative humidity table of comparisons below.
Figure BDA0000478509910000081
RRU is operated in the metal chassis of sealing, RRU itself is just operated in (generally, its internal work temperature is all more than 50 ℃) at higher temperature, if a small amount of water enters cabinet, moisture in cabinet can evaporate, thereby relative humidity in cabinet is increased 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 shown in Figure 2, comprising:
Step 201, each arrival while gathering the moment, utilizes temperature sensor to gather the temperature in RRU casing, utilizes humidity sensor to gather the humidity of RRU casing;
Can set collection period, determine to arrive at interval of the cycle of setting to gather the moment.
Step 202, obtains relative humidity according to the humidity gathering and the ratio of absolute humidity, the humidity that described absolute humidity utilizes humidity sensor to gather while being sealing RRU casing;
Step 203, the difference of the relative humidity that this is obtained and the temperature of this collection corresponding relative humidity on datum curve, compare with setting threshold, determine according to comparative result whether RRU casing intakes, wherein, described datum curve be in advance in the time that RRU casing is not intake set up temperature of reaction and the curve of relative humidity corresponding relation.
If RRU casing is not intake, relative humidity corresponding to temperature gathering should be just on datum curve, if the water inlet of RRU casing, the corresponding relative humidity of temperature should be on datum curve, therefore, can determine by comparative result whether RRU casing intakes.
The embodiment of the present invention is utilized the work characteristics of RRU high temperature, thus RRU start after temperature be generally the higher moisture evaporation of causing, water inlet detection scheme is improved, the corresponding relation of serviceability temperature and humidity, has solved the RRU difficult problem that cannot detect of intaking; By RRU being carried out to long-term lasting monitoring, be convenient to find the potential faults of RRU water inlet, occur just can effectively identify early stage in fault, avoid occurring real fault.
Alternatively, at the inner temperature and moisture sensors of installing of RRU, by management interface, the temperature and humidity of RRU inside is uploaded to processor, processor is each RRU building database, and this processor can be the processor on external server.The common water enter cause of RRU is that air locking is aging, the aging time that need to be longer of sealing RRU box sealing device, therefore within sealing RRU casing a period of time, can think that casing seals.Processor is that each RRU sets up datum curve based on database, specifically can adopt following mechanism.
After sealing RRU casing, carry out following gatherer process to meeting termination condition:
Determine while utilizing temperature sensor to collect a design temperature, utilize humidity sensor to gather humidity, determine that according to the humidity gathering and the ratio of absolute humidity the relative humidity that this design temperature is corresponding forms original data set [F, H], wherein the variation range of F is-10~90 ℃, H variation range is 0%~100%, default multiple F.Because RRU is relative closure, therefore, for each temperature value F, its relative humidity H is also substantially invariable.
When gatherer process finishes, for each design temperature F, in the time that the mean square deviation of all relative humidity corresponding to this design temperature is not more than setting thresholding, according to the mean value of all relative humidity corresponding to this design temperature, obtain the relative humidity that this design temperature is corresponding;
The relative humidity corresponding according to all design temperatures obtains datum curve, can be specifically to do linear smoothing processing.
Alternatively, while reaching following arbitrary condition, determine and meet termination condition:
1) gather duration and reach while setting duration, determine and meet termination condition;
For RRU casing, when RRU casing cuts out, temperature is lower, conventionally approaches normal temperature.After RRU starts, temperature can raise; conventionally more than can rising to 50 degree; therefore; carry out one-shot process; can collect relative humidity corresponding to preset temperature value; can be according to the start-up period of RRU, a period is set, guarantee to finish gatherer process after multiple preset temperatures are gathered repeatedly to relative humidity.
2), for each design temperature, when the number of times that collects this design temperature reaches at least N time, determine and meet termination condition.
Finish like this after gatherer process, each temperature value has been obtained after minimum N secondary data, relative humidity corresponding to each preset temperature is got to mean square deviation and obtain [F1, H1], [F2, H2] ..., [Fn, Hn], if be not more than setting thresholding, illustrate that data can use, can form the datum curve of temperature-relative humidity of this RRU.
3), for part design temperature wherein, when the number of times that collects this design temperature reaches at least N time, determine and meet termination condition.
There is no need by the time to gather each preset temperature and gathered at least N secondary data, as N-3 preset temperature therein collects at least N secondary data, also can finish gatherer process, if some value disappearance can be done linear smoothing processing, supply missing data.
The embodiment of the present invention is for each temperature value, in the time getting mean square deviation, if the mean square deviation of all relative humidity corresponding to this design temperature is not more than setting thresholding, gets its mean value as reference data.Alternatively, if mean square deviation is greater than thresholding, do not form the datum curve of temperature-relative humidity of this RRU, the initial installation of the equipment that is judged to be is poorly sealed, sends warning information, notifies the upper station of maintainer to check.
