Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example one
Referring to fig. 1, a method for determining a service life of a wind speed sensor according to a first embodiment of the present invention is shown, where the method for determining a service life of a wind speed sensor can be implemented by software and/or hardware, and the method specifically includes steps S01 to S03.
And step S01, acquiring wind speed data uploaded by a wind speed sensor, and constructing a corresponding wind speed curve graph according to the wind speed data.
It should be noted that the wind speed sensor will start to monitor the wind speed at its location in real time all the time or once the wind is detected, and package and upload the wind speed and the monitoring time monitored within a period of time (e.g. 1 minute, 1 hour or 24 hours). For this purpose, the wind speed data may be minute wind speed data, hour wind speed data, or 24-hour wind speed data, and the wind speed data specifically includes time and a wind speed corresponding thereto. A wind speed profile can thus be constructed with time on the abscissa and wind speed on the ordinate, as shown in fig. 2.
And step S02, determining the low-speed response time of the wind speed sensor according to the wind speed graph, wherein the low-speed response time is the response time of the wind speed sensor when the wind speed is increased from zero to a wind speed threshold value.
It should be noted that the principle of the wind speed sensor is as follows: when wind blows, wind can drive the wind cups of the wind speed sensors to rotate, the wind cups rotate faster when the wind speed is higher, and a one-to-one correspondence relationship exists, so that the wind speed can be inferred through the rotating speed of the wind cups.
However, since the cup of the wind speed sensor is affected by the aging of the bearing and the harsh environment such as dust, sand, etc., the rotational resistance of the cup increases with the increase of the service life, so that the low-speed response time of the wind speed sensor is slow, i.e., the time for the cup to reach the preset rotational speed from zero, i.e., the time for the cup to completely rotate, is longer than that for a new wind speed sensor which is just put into use. As shown in FIG. 2, curve a represents a new wind speed sensor, curve b represents an old wind speed sensor that is close to or has reached its useful life, and when the wind speed increases from zero to a wind speed threshold S (e.g., 10 m/S), the response time required by the new wind speed sensor is T1, while the response time required by the old wind speed sensor is T2, and T2 is significantly greater than T1.
And step S03, determining the service life of the wind speed sensor according to the low-speed response time of the wind speed sensor.
In specific implementation, different service lives can be calibrated according to different low-speed response time experiments, so that after the low-speed response time is determined, the service life of the corresponding wind speed sensor can be directly inquired and determined, and for example, when the low-speed response time is greater than a certain threshold value, it is determined that the wind speed sensor has reached the service life.
In summary, in the method for determining the service life of the wind speed sensor in the above embodiment of the invention, the low-speed response time is determined from the wind speed data monitored by the wind speed sensor, and the low-speed response time of the wind speed sensor increases with the increase of the service life due to the influence of aging of devices, dust, sand, and other severe environments, so that the current service life of the wind speed sensor can be estimated and determined according to the current low-speed response time. According to the scheme, the wind speed data monitored by the wind speed sensor is used as a data basis for estimating the service life of the wind speed sensor, so that the influence of various factors on the wind speed sensor is fully considered, and the estimation reliability of the service life of the wind speed sensor is improved.
Example two
Referring to fig. 3, a method for determining a lifetime of a wind speed sensor according to a second embodiment of the present invention is shown, where the method for determining the lifetime of a wind speed sensor can be implemented by software and/or hardware, and the method specifically includes steps S11 to S17.
And step S11, acquiring wind speed data uploaded by a wind speed sensor, and constructing a corresponding wind speed curve graph according to the wind speed data.
And step S12, determining the low-speed response time of the wind speed sensor according to the wind speed graph.
Wherein the low speed response time is the response time of the wind speed sensor when the wind speed increases from zero to a wind speed threshold.
Step S13, it is determined whether the low speed response time of the wind speed sensor is equal to or greater than a first time threshold.
When the low-speed response time of the wind speed sensor is judged to be greater than or equal to the first time threshold value, the step S14 is executed; when it is determined that the low speed response time of the wind speed sensor is less than the first time threshold, step S15 is performed. The first time threshold may be a low-speed response time obtained by performing an experimental test on the wind speed sensor having reached the service life.
And step S14, judging that the wind speed sensor reaches the service life.
And step S15, judging whether the low-speed response time of the wind speed sensor is larger than or equal to a second time threshold value. When the low-speed response time of the wind speed sensor is judged to be greater than or equal to the second time threshold value, the step S16 is executed; and when the low-speed response time of the wind speed sensor is judged to be smaller than the second time threshold, the low-speed response time of the wind speed sensor is close to the standard low-speed response time of the new wind speed sensor, and the long service life of the wind speed sensor is judged. Wherein the second time threshold may be a low speed response time determined in a preset ratio (e.g., 0.3) based on the first time threshold.
Step S16, calculating a target ratio between the low speed response time and the first time threshold.
And step S17, calculating the service life of the wind speed sensor according to the target proportion and the rated service life of the wind speed sensor.
Wherein the wind speed sensor's useful life = the rated useful life x the target proportion.
That is, in the present embodiment, the specific strategy for determining the service life according to the low-speed response time is as follows: when the low-speed response time of the wind speed sensor is greater than or equal to a first time threshold value, the wind speed sensor is directly judged to have reached the service life and needs to be replaced or maintained as soon as possible; when the low-speed response time of the wind speed sensor is smaller than the first time threshold but larger than or equal to the second time threshold, the influence of the aging of devices and the adverse environment such as dust, sand and wind is present at the moment, and the low-speed response time of the wind speed sensor is already influenced, a target proportion between the low-speed response time and the first time threshold is calculated, then the service life of the wind speed sensor is obtained by multiplying the rated service life of the wind speed sensor by the target proportion, for example, when the target proportion is 0.5, the service life of the wind speed sensor is represented to be half; and when the low-speed response time of the wind speed sensor is judged to be smaller than the second time threshold, the low-speed response time of the wind speed sensor is close to the standard low-speed response time of the new wind speed sensor, and the wind speed sensor is not greatly influenced, so that the long service life of the wind speed sensor is judged.
EXAMPLE III
Referring to fig. 4, a method for determining a lifetime of a wind speed sensor according to a third embodiment of the present invention is shown, where the method for determining the lifetime of a wind speed sensor can be implemented by software and/or hardware, and the method specifically includes steps S21 to S26.
And step S21, acquiring wind speed data uploaded by a wind speed sensor, and constructing a corresponding wind speed curve graph according to the wind speed data.
And step S22, determining the low-speed response time of the wind speed sensor according to the wind speed graph, wherein the low-speed response time is the response time of the wind speed sensor when the wind speed is increased from zero to a wind speed threshold value.
And step S23, determining the service life of the wind speed sensor according to the low-speed response time of the wind speed sensor.
Step S24, judging whether a target interval section with the wind speed reduced from the wind speed threshold value to zero exists in the wind speed curve chart. When it is determined that there is a target interval in the wind speed graph in which the wind speed decreases from the wind speed threshold to zero, representing that the wind gradually stops for a period of time, step S25 is executed; otherwise, the monitoring is continued without action.
Step S25, determining the response time of the wind speed sensor for speed reduction according to the target interval, wherein the response time of the wind speed sensor is the response time of the wind speed sensor when the wind speed is reduced from the wind speed threshold to zero.
And step S26, verifying the service life of the determined wind speed sensor according to the speed reduction response time.
Similarly, because the wind cup of the wind speed sensor can be influenced by the ageing of the bearing and the severe environments such as dust, sand and the like, the rotating resistance of the wind speed sensor can be increased along with the increase of the service life, so that the deceleration response time of the wind speed sensor is short, namely, the wind speed sensor stops rotating very quickly because the time required for reducing the preset rotating speed to zero is shorter than the time required for just putting into use of a new wind speed sensor. As shown in FIG. 5, curve a represents a new wind speed sensor, curve b represents an old wind speed sensor that is close to or has reached its useful life, and when the wind speed drops from a wind speed threshold S (e.g., 10 m/S) to zero, the response time required for the new wind speed sensor is T3, while the response time required for the old wind speed sensor is T4, and T4 is significantly less than T3.
Therefore, after the service life of the wind speed sensor is determined, if a target interval in which the wind speed is reduced from the wind speed threshold value to zero exists in the current wind speed curve diagram, the determined service life of the wind speed sensor is also verified through the speed reduction response time. The specific verification process may be that when the ratio of the deceleration response time to the third time threshold is greater than a preset ratio, it is determined that the service life verification of the determined wind speed sensor passes, and when the ratio of the deceleration response time to the third time threshold is not greater than the preset ratio, it is determined that the service life verification of the determined wind speed sensor does not pass; the third time threshold is the deceleration response time tested by taking the wind speed sensor which has reached the service life, and the preset proportion is preferably greater than or equal to 0.8, namely when the deceleration response time is close to, equal to or exceeds the third time threshold, the service life of the wind speed sensor is really reached, and the verification is passed; otherwise, the verification is not passed, and the judgment can be made again by combining the next wind speed data, so that the misjudgment is avoided, and the reliability is provided.
Example four
The fourth embodiment of the present invention further provides a method for determining the service life of a wind speed sensor, wherein the method in this embodiment is different from the method in the first embodiment in that: after the step of determining the service life of the wind speed sensor according to the low speed response time of the wind speed sensor, the method further comprises the following steps:
acquiring corresponding wind cup starting wind speed according to the determined service life of the wind speed sensor, wherein the wind cup starting wind speed is the minimum wind speed required by the wind cup of the wind speed sensor to start rotating;
and correcting the wind speed data according to the starting wind speed of the wind cup, reconstructing a corresponding wind speed curve graph according to the corrected wind speed data, and obtaining and outputting the corrected wind speed curve graph.
It should be understood that after the cup of the wind speed sensor is affected by the aging of the bearing and the adverse environment such as dust, sand, etc., the starting wind speed of the wind speed sensor increases, that is, when the wind speed is low, the cup does not rotate (that is, the phenomenon that the small wind does not rotate and the large wind does not rotate occurs), so that the quality of the wind speed observation data is reduced.
Therefore, in this embodiment, the starting wind speed of the wind cup of the wind speed sensor under different service lives is calibrated through experiments, and then after the service life of the wind speed sensor is determined, the wind speed curve graph is corrected, wherein the correction process is as follows: and replacing the wind speed (zero) of the zero wind speed time point of the low-speed response section in the wind speed data with the corresponding wind cup starting wind speed, so as to correct the wind speed data, and reconstructing a corresponding wind speed curve graph based on the corrected wind speed data, thereby realizing the correction of the wind speed curve graph.
For example, as shown in fig. 2, the wind speed gradually increases from zero from time t, but since the start-up wind speed exists, the wind speed at time t is not zero, but the wind speed is started up for the corresponding cup, so that the wind speed at time t can be replaced by the corresponding cup start-up wind speed, the wind speed data can be corrected, and finally, the wind speed graph can be reconstructed based on the corrected wind speed data and outputted. The corrected wind speed curve graph is output, so that a subsequent meteorological department can make correct judgment according to the wind speed curve graph, wrong judgment caused by that the wind speed is not corrected in time after the starting wind speed is increased is avoided, the service life of the wind speed sensor is indirectly and visually reflected on the curve graph, and subsequent related personnel can make judgment conveniently.
It should be noted that the above embodiments and features thereof may be combined arbitrarily without conflict, and a new technical solution obtained by combining the embodiments and features thereof still belongs to the protection scope of the present invention.
