Technical Field
The invention relates to a flow monitoring method of intelligent water meters, belonging to the technical field of flow monitoring.
Background
With the increase of the demand of people, the water meter not only has the single function of metering, and can provide convenience for the detection of water consumption of people through the intelligent function set for the water meter, at present, generally extracts data in the aspects of water temperature, impurities and water pressure, particularly, can directly reflect whether the water supply is sufficient and stable and whether the pipeline has leakage and the like through the water pressure data, but the water meter is only used for detecting and giving out a warning, and cannot actively and timely and effectively solve the problems, or cut off the water flow, particularly, the water consumption is firstly bought and then the water is used in the current family, when the water pipe bursts because of the quality problem of the water pipe or the influence of winter climate, the purchased water is completely consumed, and the valve is closed only when the water quantity is insufficient, so that the waste of resources is caused.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a flow monitoring method for intelligent water meters, which is used for monitoring water consumption information in real time.
In order to achieve the purpose, the invention adopts the technical scheme that the flow monitoring method of intelligent water meters comprises the following specific steps:
(1) a base meter part in the water meter measures the water flow speed in the water pipe in real time and sends the measured data to a master control system in real time;
(2) the master control system receives data every 1 second;
(3) eliminating data with a value of zero, judging whether an average value of minutes exists or not, judging whether sixty effective numerical values are received or not if the average value of minutes does not exist, receiving the sixty effective numerical values, calculating a mean value of minutes, storing the mean value into a register, calculating a mean value of minutes every time sixty effective numerical values are received, and storing the mean value into the register;
(4) determining minute mean range from the received at least sixty minute means;
(5) the main control system continuously receives the data and calculates minute mean value, and judges whether the real-time value is in the mean value range of minutes, if not, the main control system determines that the water pipe burst problem occurs, the water supply is turned off by controlling the electromagnetic valve of the water pipe, and if the real-time value is in the determined mean value range of minutes, the main control system continuously receives the data;
(6) the master control system continues to receive data and judges whether -hour mean values exist, and after sixty mean values of minutes are received, the mean values of hours are calculated and stored in a register;
(7) determining a hour mean range from the received at least twenty-four hour means;
(8) the main control system judges whether the average value of minutes and the average value of hours exist at present, judges whether the real-time value is in the average value range of hours, if not, the main control system determines that the water pipe burst problem occurs, the water supply is turned off by controlling the electromagnetic valve of the water pipe, and if the real-time value is in the determined average value range of hours, the data continues to be received;
(9) the main control system judges whether the mean value of days exists or not while judging whether the real-time value is in the mean value range of hours, and calculates the mean value of days after receiving the twenty-four mean values of hours;
(10) determining a day average range according to the received plurality of day averages;
(11) the main control system judges whether the current average value of minutes, the average value of hours and the average value of days exist, when the average value of days exists, whether the real-time value is in the range of the average value of days is judged, if the real-time value is not in the range, the main control system judges that the water pipe burst problem occurs, the water supply is turned off by controlling the electromagnetic valve of the water pipe, if the real-time value is in the range of the determined average value of days, the data continues to be received, and the judgment is continued.
The method has the advantages that the mean value of minutes, the mean value of hours and the mean value of days are determined through the master control system, so that the mean value range of days is more and more relatively stable states, the water flow of the water inlet of the water pipe is measured in real time, the problem of bursting of the water pipe is protected timely and quickly, and accidents caused by abnormal flow are avoided.
