The embodiment of the application also discloses a monitoring system for the pipeline flow. Referring to fig. 2, the monitoring system for pipeline flow comprises a plurality of electromagnetic flow meters, and a cloud server 5 connected with the electromagnetic flow meters in communication.

The embodiment of the application also discloses a method for monitoring the flow of the pipeline.
Referring to fig. 3, the method for monitoring the flow rate of the pipeline includes:
s1, acquiring a monitoring area and a current time point of a pipeline;
s2, judging whether the current time point is matched with a preset first time period or not;
s3, if the current time point is matched with the first time period, acquiring a monitoring instruction of the entertainment area;
s4, monitoring the pipeline of the entertainment area based on the entertainment area monitoring instruction;
s5, if the current time point is not matched with the first time period, judging whether the current time point is matched with a preset second time period;

s8, if the current time point is not matched with the second time period, acquiring a command to be monitored;
and S9, stopping performing alarm monitoring on the pipeline of the living area based on the instruction to be monitored.
The peak time and peak area of water use are different for different time periods in different regions. For the living area, the water consumption is more in the daytime, and the water consumption is less when residents rest at night, so that the water consumption peak period for the living area is night. For the entertainment area, more people are in the afternoon to the evening, and less people are in the daytime, so that the low peak time of water consumption in the entertainment area is the morning time.
At this time, the pipeline flow of the living area and the entertainment area is measured at the same time, if the pipeline flow is measured in the low peak period of the water consumption of the living area, the data monitored in the entertainment area is inaccurate, and similarly, the pipeline flow is measured in the low peak period of the water consumption of the entertainment area, the data monitored in the living area is inaccurate.
Therefore, the flow rates of the pipelines in different areas need to be measured respectively, so that the current time point is obtained at this time, and the obtaining mode can be recorded by a timer or a timing system. Simultaneously, a monitoring area of the pipeline is obtained, wherein the monitoring area comprises a living area and an entertainment area. The acquisition mode of the monitoring area can be obtained by a position sensor.
And then judging whether the current time point is matched with a preset first time period, wherein the first time period is the time period of the water consumption peak period of the entertainment area, obtaining historical measurement data in an obtaining mode, then obtaining the starting time and the ending time of the lowest peak of the historical water consumption of the entertainment area, and then taking the starting time, the ending time and the time between the starting time and the ending time as the first time period.
And judging whether the current time point is matched with the first time period, namely judging whether the current time point is positioned between the first time periods, if so, proving that the current time point is matched, and otherwise, judging that the current time point is not matched. If the flow rate of the pipeline in the entertainment area is matched with the flow rate of the pipeline in the entertainment area, the flow rate of the pipeline in the entertainment area can be monitored, so that a monitoring instruction of the entertainment area is obtained at the moment, and the corresponding flow rate sensor is controlled to be electrified to work according to the monitoring instruction of the entertainment area, thereby monitoring the flow rate of the pipeline in the entertainment area.
If not, the monitoring is not suitable for the entertainment area, and then whether the current time point is matched with a preset second time period or not is judged, wherein the second time period is a water consumption peak period of the living area, and the acquisition mode is the same as that of the first time period.
And if the current time point is matched with the second time period, a living area monitoring instruction is obtained, and then the flow sensor of the living area is controlled to be electrified to work according to the living area monitoring instruction, so that the pipeline flow of the living area is monitored.
If the current time point is not matched with the second time period, the current time point is proved to be neither the monitoring time period of the living area nor the monitoring time period of the entertainment area, the instruction to be monitored is obtained at the moment, the flow sensors for monitoring abnormal flow in the living area and the entertainment area are controlled to be not electrified through the instruction to be monitored, the alarm monitoring of the living area and the entertainment area is stopped, and therefore energy can be saved.
It should be understood that the flow sensors that monitor normal flow usage in the living and recreational areas are normally powered on. Therefore, by the mode, the accuracy of monitoring the flow of the pipeline in different areas and different time periods can be improved, and the possibility of the occurrence of flow monitoring error is reduced.
Referring to fig. 4, further, in order to improve the accuracy of determining whether the pipeline flow leaks, in another embodiment, the method for monitoring the pipeline flow further includes:
s11, acquiring a monitoring instruction type;
s12, when the monitoring instruction type is determined to be an entertainment area monitoring instruction, acquiring the pipeline monitoring flow of the entertainment area as the entertainment area flow;
s13, judging whether the flow of the entertainment area is larger than a preset first flow;
s14, if the flow of the entertainment area is larger than the first flow, acquiring flow leakage warning information of the entertainment area;
s15, when the monitoring instruction type is determined to be a living area monitoring instruction, acquiring the pipeline monitoring flow of the living area as the living area flow;
s16, judging whether the flow of the living area is larger than a preset second flow;
and S17, if the flow of the living area is larger than the second flow, acquiring the flow leakage warning information of the living area.
Specifically, the monitoring instruction type is obtained in the process of monitoring the living area or the entertainment area through the monitoring instruction. The monitoring instruction types comprise an entertainment area monitoring instruction and a living area monitoring instruction.
When the monitoring instruction type is determined to be the entertainment area monitoring instruction, the pipeline monitoring flow of the entertainment area is obtained at the moment and is used as the entertainment area flow, and the obtaining mode is that the pipeline flow of the pipeline of the entertainment area in a preset time length is measured through an electromagnetic flowmeter.
And then judging whether the flow of the entertainment area is greater than a preset first flow, wherein the first flow is the maximum flow obtained within a preset time according to historical monitoring data. And the first flow is a range value comprising an upper limit value and a lower limit value, and whether the flow of the entertainment area is greater than the first flow is judged, namely whether the flow of the entertainment area is greater than the upper limit value of the first flow is judged.
If the flow of the entertainment area is larger than the first flow, the fact that the entertainment pipeline is likely to leak is proved, and therefore the flow leakage warning information of the entertainment area is obtained and sent to the corresponding display to be displayed, and therefore relevant workers can be reminded. If the entertainment area traffic is not greater than the first traffic, no processing may be performed at this time.
And when the monitoring instruction type is determined to be a living area monitoring instruction, acquiring the pipeline monitoring flow of the living area as the living area flow, wherein the acquisition mode is the same as the acquisition mode of the entertainment area flow. And then judging whether the flow of the living area is greater than a preset second flow, wherein the second flow is the maximum flow obtained within a preset time according to historical monitoring data. And the second flow is a range value, including an upper limit value and a lower limit value, and whether the living area flow is greater than the second flow is judged, namely whether the living area flow is greater than the upper limit value of the second flow is judged.
If the flow of the living area is larger than the second flow, the fact that the living pipeline is likely to leak is proved, and therefore the flow leakage warning information of the living area is obtained and sent to the corresponding display to be displayed, and therefore relevant workers can be reminded. If the living area flow is not greater than the second flow, no treatment may be performed at this time. Therefore, whether the pipeline in the living area or the entertainment area leaks or not can be determined in time in the mode.
Referring to fig. 5, in order to improve the accuracy of monitoring the abnormal flow rate of the pipeline, in another embodiment, after monitoring the pipeline of the living area based on the living area monitoring instruction, the method further includes:
s21, acquiring historical water consumption data and historical drainage data for monitoring the pipeline;
s22, obtaining an average water-drainage ratio based on historical water use data and historical drainage data;
s23, obtaining the current water consumption and the current water displacement within a preset time length;
s24, obtaining a current water-drainage ratio based on the current water consumption and the current drainage;
s25, judging whether the current water consumption-drainage ratio is matched with the average water consumption-drainage ratio;
and S26, if the flow rate of the pipeline is not matched, generating abnormal information of the flow rate of the pipeline and outputting the abnormal information.
Specifically, after monitoring the pipeline in the living area, it is needless to say that after monitoring the pipeline in the entertainment area, historical water consumption data and historical drainage data for monitoring the pipeline may be obtained, where the historical water consumption data and the historical drainage data are both pre-stored data.
And then obtaining the average ratio of water consumption to water drainage according to the historical water consumption data and the historical water drainage data in a way of obtaining a plurality of ratios of historical water consumption to historical water drainage within the same time length, and then solving the average value of all the obtained ratios, wherein the obtained value is the average ratio of water consumption to water drainage.
Then, the current water consumption and the current water displacement in the preset time are obtained, the preset time can be set according to actual conditions, and the current water consumption and the current water displacement are obtained by measuring according to an electromagnetic flowmeter for measuring the abnormal flow of the pipeline.
And calculating to obtain the current water consumption-drainage ratio according to the current water consumption and the current drainage, namely, dividing the current water consumption by the current drainage to obtain a value, namely the current water consumption-drainage ratio. And then judging whether the current water consumption-drainage ratio is matched with the average water consumption-drainage ratio, wherein the average water consumption-drainage ratio is provided with an upper error limit value and a lower error limit value.
If the current water consumption-drainage ratio is between the upper error limit value and the lower error limit value, the current water consumption-drainage ratio is proved to be matched with the average water consumption-drainage ratio, otherwise, the current water consumption-drainage ratio is not matched. If the two are matched, the pipeline is proved to be not abnormal. If the two are not matched, pipeline flow abnormal information is generated and output to the display at the moment, so that the alarm can be given to the working personnel, the working personnel can go to the corresponding places in time to overhaul the abnormal pipeline, the accuracy of monitoring the pipeline flow abnormity can be guaranteed as far as possible, the safety of pipeline use is improved, and energy is saved.
Referring to fig. 6, in order to further determine the specific situation of the pipeline anomaly, in another embodiment, after generating and outputting the pipeline flow anomaly information, the method includes:
s31, acquiring historical water consumption in a preset time length based on historical water consumption data;
s32, acquiring historical drainage quantity in a preset time period based on historical drainage data;
s33, judging whether the current water consumption is matched with the historical water consumption;
s34, if the current water consumption is matched with the historical water consumption, determining that the abnormal information of the pipeline flow is abnormal of the drainage pipeline;
s35, if the current water consumption is not matched with the historical water consumption, judging whether the current water discharge is matched with the historical water discharge;
s36, if the current water discharge is matched with the historical water discharge, determining that the abnormal information of the pipeline flow is abnormal;
and S37, if the current water discharge amount is not matched with the historical water discharge amount, determining that the abnormal information of the pipeline flow is abnormal in the water inlet and outlet pipeline.
Specifically, after the abnormal information of the pipeline flow is generated and output, the historical water consumption within the preset time length is obtained according to the historical water consumption data, the historical water discharge within the preset time length is obtained according to the historical water discharge data, and of course, the obtained historical water consumption and the obtained historical water discharge are both provided with an upper limit value and a lower limit value.
And then judging whether the current water consumption is matched with the historical water consumption, namely judging whether the current water consumption is between the upper limit value and the lower limit value of the historical water consumption, if so, matching, otherwise, not matching. If the current water consumption is matched with the historical water consumption, and the current water consumption-drainage ratio is larger than the average water consumption-drainage ratio, the fact that the flow passing through the drainage pipeline is changed within the preset time is proved, the fact that the drainage pipeline is abnormal is proved, and the fact that the pipeline flow is abnormal and the water inlet pipeline is not abnormal is determined.
If the current water consumption is not matched with the historical water consumption, whether the current water consumption is matched with the historical water consumption or not is judged, and the judging mode is the same as the judging mode whether the current water consumption is the same as the historical water consumption or not. If the current water displacement is matched with the historical water displacement, the water discharge pipeline is proved to be normal at the moment, and therefore the fact that the water inlet pipeline is abnormal due to the fact that the pipeline flow is abnormal is determined at the moment.
And if the current water displacement is not matched with the historical water displacement, the water inlet pipeline is proved to be abnormal, and the water outlet pipeline is proved to be abnormal at the same time, so that the abnormal information of the pipeline flow is determined to be the abnormal condition of the water inlet and outlet pipeline at the same time. Therefore, by means of the mode, the fact that the pipeline is abnormal, namely the water inlet pipeline or the water drainage pipeline can be further determined, and the accuracy of judgment can be further improved.
Referring to fig. 7, in order to further determine the specific abnormal condition of the drainage pipeline, in another embodiment, after determining that the abnormal information of the pipeline flow is a drainage pipeline abnormality, the method further includes:
s41, determining the current water discharge and the historical water discharge;
s42, if the current water discharge is larger than the historical water discharge, the abnormal condition of the water discharge pipeline is the leakage of the water discharge pipeline;
s43, if the current water discharge is smaller than the historical water discharge, the water discharge pipeline is actually blocked abnormally.
Specifically, after it is determined that the flow rate abnormality information is a drain pipe abnormality, the magnitudes of the current displacement and the historical displacement, both of which are displacements taken within the same period of time, are determined. If the current water discharge is larger than the historical water discharge, the water discharge of the water discharge pipeline is proved to be suddenly increased in the same time, and the water discharge pipeline is proved to be abnormal to be the water discharge pipeline leakage.
If the current water discharge is smaller than the historical water discharge, the water discharge of the water discharge pipeline is proved to be suddenly reduced in the same time, and the water discharge pipeline is proved to be blocked abnormally at the moment.
