Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 7 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Embodiments of the invention are described in further detail below with reference to the drawings.
The embodiment of the application discloses a pipe network pressure anomaly detection method, in the process of monitoring pipe network pressure, the pressure after conversion of directly detecting pipe network pressure and temperature is utilized to analyze and judge, so that the actual pressure of the current pipe network can be detected, the situation that false alarm occurs due to overlarge pressure value measurement error at a certain moment is reduced, and the accuracy of pipe network pressure detection is improved.
Referring to fig. 1, the method flow of pipe network pressure anomaly detection includes the following steps:
step S100: and obtaining pipe network pressure information.
The pressure value corresponding to the pipe network pressure information is the pressure value born by the side wall of the water supply pipeline in the pipe network, can be obtained by installing a pressure sensor on the side wall of the pipeline, and is a routine technical means for the person skilled in the art, and is not described in detail; the pipe network pressure information is acquired at regular intervals, the specific time is adjusted by adjusting the sensitivity of the pressure sensor, and the pipe network pressure information is a conventional technical means for those skilled in the art and will not be described in detail.
Step S101: judging whether the pressure value corresponding to the pipe network pressure information falls into a preset safety range or not.
The safety range is a range where the pressure of the pipe network is allowed and set by the staff, and is set by the staff according to the actual situation, and the description is omitted; the purpose of the judgment is to know whether the pipe network pressure value measured by the pressure sensor is in a safety condition or not at present so as to facilitate the subsequent judgment of the current pressure condition of the pipe network.
Step S1011: if the pressure value corresponding to the pipe network pressure information falls into the safety range, outputting a normal pressure signal.
When the pressure value corresponding to the pipe network pressure information falls into the safety range, the current pressure of the pipe network is in the safety state, and a normal pressure signal is output to record the situation.
Step S1012: if the pressure value corresponding to the pipe network pressure information does not fall into the safety range, outputting an abnormal pressure signal.
When the pressure value corresponding to the pipe network pressure information does not fall into the safety range, the current pressure of the pipe network is in an abnormal state, and an abnormal pressure signal is output to record the condition, so that the subsequent further processing of the abnormal condition is facilitated; meanwhile, the corresponding pressure value can be judged with the maximum value and the minimum value of the safety range so as to determine the condition that the pressure has overpressure or the overpressure, which is a routine technical means for the person skilled in the art and is not described in detail.
Step S102: and counting the abnormal pressure signals in a preset detection interval to acquire abnormal quantity information.
The detection section is a region for fixing the section range, and the detection section can be used for dividing the pipeline network pressure information into a number of sections, for example, the section size of the detection section is 3, and when the pressure values corresponding to the pipeline network pressure information are sequentially 10,12,9,10 in a positive sequence arrangement on a time axis, the pressure value corresponding to the pipeline network pressure information defined by the detection section is 12,9,10; the number value corresponding to the abnormal number information is the total number of abnormal pressure signals in the detection interval, the abnormal number information is obtained through counting, the initial value of the number value corresponding to the abnormal number information is zero, and when one abnormal pressure signal is output, the number value corresponding to the abnormal number information is added with one.
Step S103: and (3) forward-sequence shifting the detection interval on a preset time axis to continuously update the pipe network pressure information in the detection interval.
The detection interval can carry out positive sequence transition on a time axis along with the collected pipe network pressure information, the positive sequence of the time axis is along the time flow direction of the daily time line, so that the pipe network pressure information collected in the detection interval can be continuously updated, for example, the interval size of the detection interval is 3, and when the pressure values corresponding to the pipe network pressure information are sequentially 10,12,9,10 in positive sequence arrangement on the time axis, the pressure value corresponding to the pipe network pressure information in the detection interval is 12,9,10; when the pressure value corresponding to the newly output network pressure information is 11, the pressure value corresponding to the network pressure information in the detection interval is updated to 9,10 and 11.
Step S104: judging whether the number value corresponding to the abnormal number information is larger than a preset safety value.
The safety value is a fixed value, the maximum number of the abnormal pressure signals allowed to occur is set by the staff, and the specific value is set by the staff according to the actual situation and is not described in detail; the purpose of the judgment is to know whether the number of the abnormal pressure signals in the current detection interval exceeds an allowable value, so that the subsequent further analysis of the condition of the pipeline pressure is facilitated.
Step S1041: and if the number value corresponding to the abnormal number information is larger than the safety value, outputting an abnormal alarm signal.
When the number value corresponding to the abnormal number information is larger than the safety value, the pipe network pressure is indicated to be in an abnormal condition, and an abnormal alarm signal is output to the dispatching center at the moment, so that external staff can timely process the abnormal condition.
Step S1042: and if the number value corresponding to the abnormal number information is not greater than the safety value, outputting a normal operation signal.
When the number value corresponding to the abnormal number information is not greater than the safety value, the pressure abnormality is caused by detecting environmental fluctuation, the pressure of the pipe network is still in a normal state, and a normal operation signal is output for recording, so that workers can conveniently learn the actual condition of the pressure of the pipe network.
Referring to fig. 2, when the abnormal pressure signal is output, the pipe network pressure abnormality detection method further includes:
step S200: and acquiring pipe network temperature information when the abnormal pressure signal is output.
When an abnormal pressure signal is output, the condition that the measured pressure is abnormal due to the influence of external environment or inaccuracy of the sensor is possibly caused by the fact that the pressure of the pipe network acquired by the pressure sensor is abnormal is described, and the pressure of the pipe network needs to be further detected and analyzed; the temperature corresponding to the pipe network temperature information is the water temperature of the pipe network pipeline, the water temperature can be obtained through a temperature sensor, and when an abnormal pressure signal is output, the temperature sensor is started to obtain the temperature.
Step S201: and according to the temperature information and the pressure information stored in the temperature database, matching with the pipe network temperature information to determine conversion pressure information.
Because the pipe network is a water distribution pipe network, the pipelines in the pipe network are all transported by water, the pressure of the water is affected by the temperature, and when the temperature is higher, the water pressure is lower; the temperature corresponding to the temperature information is the temperature of water, the pressure information is the water pressure of the water at the corresponding temperature, and the staff can use different temperature information and corresponding pressure information to perform test records so as to establish a temperature database, wherein the establishment process of the temperature database is a conventional technical means of the person skilled in the art and is not repeated; when the pipe network temperature information is input into the temperature database, the temperature database can output corresponding pressure information, namely conversion pressure information, and the pressure value corresponding to the conversion pressure information is the pipe network pressure value obtained through detecting the pipe network temperature.
Step S202: and judging whether the pressure value corresponding to the conversion pressure information falls into a safety range or not.
The purpose of the judgment is to know whether the pipe network pressure values measured by different methods meet the pressure requirement or not, so that the analysis and judgment of the state of the current pressure of the pipe network can be conveniently carried out later.
Step S2021: if the pressure value corresponding to the conversion pressure information falls into the safety range, the abnormal pressure signal is canceled and the data abnormal signal is output.
When the pressure value corresponding to the conversion pressure information falls into a safety range, the fact that the measured pressure values through two different methods are inconsistent is indicated, at the moment, the actual pressure value of the pipe network cannot be judged directly, the abnormal pressure signal is canceled to reduce the influence on the abnormal quantity information, and meanwhile, the data abnormal signal is output to record the situation, so that the follow-up further analysis of the actual pressure of the pipe network is facilitated.
Step S2022: if the pressure value corresponding to the conversion pressure information does not fall into the safety range, the abnormal pressure signal is maintained.
When the pressure value corresponding to the conversion pressure information does not fall into the safety range, the pressure values measured by the two different detection methods are abnormal, namely the pipe network pressure at the moment is in an abnormal state, and an abnormal pressure signal is output so that the abnormal quantity information can be recorded.
Referring to fig. 3, when the data anomaly signal is output, the pipe network pressure anomaly detection method further includes:
step S300: and calculating the difference between the pressure value corresponding to the pipe network pressure information and the pressure value corresponding to the conversion pressure information to obtain difference pressure information.
When the data abnormal signal is output, the fact that the pipe network pressure values measured by the two different methods are inconsistent is indicated, and at the moment, the actual pressure of the pipe network can be further analyzed; the pressure value corresponding to the differential pressure information is the differential value between the pressure value corresponding to the pipe network pressure information and the pressure value corresponding to the conversion pressure information, and the calculation formula is F 0 =F 1 -F 2 Or F 0 =F 2 -F 1 Wherein F 0 For the pressure value corresponding to the differential pressure information, F 1 F is the pressure value corresponding to the pipe network pressure information 2 To convert the pressure value corresponding to the pressure information.
Step S301: and judging whether the pressure value corresponding to the differential pressure information falls within a preset allowable range or not.
The allowable range is the pressure difference value of the allowed two pressure values set in advance, the allowable range is (-a, a), a is a positive number and is set by staff according to the actual situation, wherein-a is the minimum value allowed by the pressure difference value, and a is the maximum value allowed by the pressure difference value, and the purpose of judgment is to know whether the difference value of the two pressure values is in the allowable range or not so as to further analyze the pipe network pressure.
Step S3011: and if the pressure value corresponding to the differential pressure information does not fall in the allowable range, canceling the data abnormal signal.
When the pressure value corresponding to the differential pressure information does not fall into the allowable range, the fact that the differential value of the pipe network pressure values measured by the two different methods is large is indicated, namely the current actual pressure condition of the pipe network cannot be directly determined, and the data anomaly signal is canceled so as not to further analyze the data.
