Description
Technical Field
The invention relates to the field of communication, in particular to a method and a device for diagnosing pipeline abnormity.
Background
At present, people's living tends to be intelligentized more and more, and the technology updating for creating household health environment is particularly prominent, wherein the health water system is the most widely researched and improved by various manufacturers. In the prior art, there are many improved methods and devices for water detection, and there are major drawbacks for water stability applications.
In practical situations, since many sensors detecting water use have a constant detection of the pressure value of the sensed variable, it is necessary to ensure that the water use environment is not disturbed by the external environment, such as a pipeline. Meanwhile, because of the fluctuation and variation relationship of the ambient temperature of the water pipe (such as in winter, summer and under humid environment), the water pressure in the water pipe fluctuates along with the change of the ambient temperature or the heat conduction temperature of the electromagnetic valve, which causes certain misjudgment on the sensing result of the sensor of the water purifier, for example. For another example, when the average temperature of the water is 5-10 ℃ and the average ambient temperature is 20 ℃, after the predetermined length of the pipe is sealed by the valve, the water temperature slowly rises due to the ambient heat conduction of the pipe itself, and the volume of the pipe gradually increases due to the expansion coefficient of the water, so that the water pressure fluctuates, if there is a slight leakage on the surface (or at the joint) of the pipe. One situation is that the variation of the local pressure fluctuation accompanying such leakage may approach to be offset by the variation of the local pressure accompanying the increase of the water temperature, and at this time, it may be impossible to determine whether or not there is a water leakage from, for example, a water purifier device or a pressure meter. Similarly, if hot water of 90 ℃ is supplied and the average ambient temperature is 10 ℃, the temperature of the water supplied to the pipe gradually decreases due to heat conduction, resulting in a decrease in the internal pressure of the pipe, which may cause erroneous judgment of the water quality detection apparatus, for example.
Aiming at the problem that the accuracy rate of the abnormity diagnosis of the pipeline is low in the related technology, an effective solution does not exist at present.

Alternatively, the execution subject of the above steps may be a terminal or the like, but is not limited thereto.
As an alternative implementation, as shown in fig. 3, which is a schematic structural diagram of a detection system according to an alternative embodiment of the present invention, the pressure detection system of the pipeline mainly includes: pressure sensor, temperature sensor, wherein, pressure sensor is used for gathering pipeline inner wall pressure value, and temperature sensor is used for gathering the interior liquid temperature of pipeline, and the liquid in the pipeline can be water, oil or chemical liquid. The pressure sensor and the temperature sensor can be arranged on (or nearby) the water inlet electromagnetic valve of the pipeline. The controller is used for controlling the pressure sensor and the temperature sensor. The pipeline can be the pipeline in the water purifier, and the controller can communicate with the control mainboard intercommunication of water purifier in order to transmit detection data information.
As an alternative embodiment, the temperature of the liquid in the pipeline can be collected by a temperature sensor mounted on the pipeline, and the pressure value of the inner wall of the pipeline can be collected by a pressure sensor mounted on the pipeline. The method comprises the steps of setting a preset time interval for collection, determining inner wall pressure values (a first pressure value and a second pressure value) of a pipeline at two time points if the liquid temperature values in the pipeline at the two time points (the first time point and the second time point) are equal, calculating a difference value delta P of the two inner wall pressure values, and determining whether the pipeline leaks or not according to the inner wall pressure difference value. In the present embodiment, in order that the time difference between the first time point and the second time point may be greater than the preset threshold, the preset threshold may be determined according to actual situations, for example, 1 minute, 5 minutes, 10 minutes, and the like. The span condition of the time difference can satisfy the time points containing possible leakage of liquid, so that the situation of leakage misjudgment caused by over-close of the two time points is prevented.

As an alternative embodiment, the first preset threshold pthIt can be determined according to the actual situation if the measured Δ P > PthThen the exception running total, which may be leak count +1, is incremented by one, and leak count +1 is incremented. The second preset threshold may be determined according to practical situations, for example, 3, 5, etc. Taking the second preset threshold value as 3 for example, if the leakage count is greater than or equal to 3, the pipeline is considered to be leaking.
Optionally, determining whether the target pipeline is abnormal according to the difference includes: adding one to the normal accumulated value of the target pipeline under the condition that the difference value is determined to be smaller than a first preset threshold value; and under the condition that the normal accumulated value of the target pipeline is determined to be larger than or equal to a third preset threshold value, determining that the target pipeline is normal.
As an alternative embodiment, if Δ P is measured<pthThen the normal running total is incremented by one. The third preset threshold may be determined according to practical situations, such as 8, 10, etc. Taking the third preset threshold value as 10 as an example, if the normal accumulated value is greater than or equal to 10, the pipeline is considered to be normal, and no leakage occurs. The judgment for many times is for fault tolerance and prevents abnormity and errors in acquisition.
Optionally, obtaining a temperature value of the liquid in the target pipeline includes: and acquiring the inner wall pressure value of the target pipeline every preset time, and acquiring the temperature value of the liquid in the target pipeline under the condition that the inner wall pressure value of the target pipeline does not rise in a preset time period.
As an alternative embodiment, the pressure sensor collects the pressure value of the inner wall of the pipeline every predetermined time interval (such as 1s), and the initial temperature value of the liquid in the pipeline is measured when the pressure value does not rise for a period of time.
As an alternative embodiment, the present application is described below by way of a specific example.
In a pressure detection system, a liquid (e.g., tap water) is generally considered to have a volume expansion coefficient δ of water input into a pipe at normal temperature and pressurekSatisfies the following conditions:
that is, the change in water volume Δ V ═ δ due to the change in water temperature can be understood ask·V·ΔTkTemperature variation DeltaT of water in different sealed pipe spaceskThe volume V of water in the closed space is constant and the volume expansion coefficient deltaiIn inverse proportion. Under the above-mentioned general environmental conditions, the inner wall of the water pipe bears the pressure to volume expansion coefficient deltakThe effect of the amount of change in (c) is not significant. Thus according to the relation:
and the relation (1) shows that the average pressure change delta P in the current pipeline satisfies:
it can be known that the pressure change of the liquid to the inner wall of the pipeline can be used for judging whether the leakage exists or not under the condition of temperature change. Where W represents the modulus of elasticity of the pipe and η represents the poise coefficient of the pipe material, and it is assumed in equation (3) that the water pipe itself is in an air environment rather than being embedded in a building material (e.g., cement, etc.), and the pressure difference existing between the inner and outer walls of the pipe can be ignored. S represents the radius ratio of the inner wall and the outer wall of the water conveying pipeline, and the pipeline column body is supposed to extend integrally and evenly. Under the above conventional environmental conditions, when the temperature is kept constant, the volume E of the water pipeline should satisfy:
E＝Vin+V(τ) (4)
here VinIs the volume of water when the pressure on the inner wall of the pipeline is unchanged (i.e. the starting node), and V (τ) is a function of the volume change of the accumulated water with the metering time τ, i.e. a continuous leakage condition is considered to occur. Based on this, the volume change V (τ) of water is:
V(τ)＝VΔP+VΔT
wherein VΔPIs a volume change function of the water at the volume with the change of the internal pressure, VΔTIs a function of the volume change of the water at that volume as a function of the conduction temperature.
Based on the above principle, as shown in fig. 4, a schematic flow chart of the pipeline anomaly detection according to an alternative embodiment of the present invention is shown, and an embodiment of the specific detection method includes the following steps:
s1, judging whether the average pressure change delta P in a set time variable tau (such as 1h) does not exceed a preset critical value P according to the leakage of one pipeline which is currently provided with the electromagnetic valveth(first preset threshold).
And S2, inputting the test condition to the control board. When the detection is started, the control panel closes the electromagnetic valve B and opens the electromagnetic valve A to enable the liquid to flow into the pipeline.
S3, collecting the pressure value of the inner wall of the pipeline at every preset time interval (such as 1S) by the pressure sensor of the controller driving the electromagnetic valve A, B, closing the electromagnetic valve A after the pressure value does not rise for a period of time, and the purpose is to enable the internal pressure of the cavity of the current closed pipeline to reach the maximum so as to determine the initial pressure value and the volume V of waterin(i.e. the volume E of the current pipe) and determining a current initial temperature value Tin。
S4, collecting instant pressure value according to the preset time interval to determine delta P, and controlling the temperature sensor to sense the temperature value of the water to determine delta TkThe recording is performed while recording a time interval period (such as every 30s) of continuous acquisition.
And recording the newly acquired data, searching and judging whether the same temperature point exists before the time, if not, continuing to step S4, and if so, entering the next step.
S5, if the difference value delta P between the pressure values at the first time point and the second time point is measured at present and is more than Pth. Then the leak count +1 (corresponding to the abnormal running total plus one) is greater than a first predetermined threshold, the pipeline is considered to be leaking, whereas the no leak count +1 (corresponding to the normal running total plus) is greater than or equal to a second predetermined threshold, the pipeline is considered to be not leaking. The judgment for many times is for fault tolerance and prevents abnormity and errors in acquisition.
In step S5, the control board is configured to acquire and recognize Δ P and Δ T in accordance with the set time variable τkSo as to generate an evaluation index H (τ) for the presence or absence of leaks in the pipe according to the following logic:
wherein c (delta)k) Is the volume expansion coefficient delta for waterkT (τ) is a function of the change in water temperature with time, P (τ) is a function of pressure with timeA function of the change in time.
The real-time pressure detection of this application to the conduit avoids temperature disturbance factor, lets pressure detection and contrast keep going on under same temperature to get rid of the influence that the temperature judged to the sensor component, made it be applicable to the state detection in the conduit under different expansion coefficients, especially under the great change's of expansion coefficient the condition. Meanwhile, the pressure detection system of the water purifier adopts a full-automatic program-controlled detection mode, so that artificial detection errors are prevented, the efficiency is improved, and the labor cost is saved.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
