[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The process steps that have been named or numbered can change the execution order according to the technical purpose to be achieved, as long as the same or similar technical effects can be achieved. The division of modules in this application is a logical division. There may be other division methods when it is implemented in actual applications. For example, multiple modules can be combined or integrated into another system, or some features can be ignored or not executed. In addition, the mutual coupling or direct coupling or communication connection shown or discussed can be through some interfaces, and the indirect coupling or communication connection between units can be electrical or other similar forms, which are not limited in this application. In addition, the modules or submodules described as separate components may or may not be physically separated, may or may not be physical units, or may be distributed in multiple circuit units, and some or all of the units may be selected according to actual needs to achieve the purpose of the present application.

[0027] In the related art, the characteristics of complex devices and numerous processes make it easy to produce quality risks in the process of mass manufacturing smart water meters, so it is necessary to set up necessary detection processes for the functions of smart water meters. In the related art, the reliability of the valve system of the smart water meter is judged by continuously sampling the current of the valve action process of the smart water meter under no-load conditions. However, the reliability of detecting the valve of the smart water meter through a single current threshold is low, and it cannot fully and effectively reflect the working characteristics of the water meter valve.

[0028] Figure 1 The present invention provides a test system for a smart water meter. Figure 1As shown, build a test system. Use a current acquisition module in series between the power supply battery and the water meter under test. The current module is equipped with a communication line, which can transmit data in real time and collect the power supply current value of the smart water meter. The voltage acquisition module is connected in parallel at both ends of the power supply battery and is equipped with a communication line to transmit the voltage sampling value in real time. Use wired or wireless communication to connect the water meter under test. Since the current of the smart water meter only needs a few microamperes when it is working, and the current when the valve is actuated requires tens of milliamperes, the difference between the two is relatively large, and the data impact of the working current on the valve action current can be ignored.

[0029] By adopting Figure 1 The test system in the intelligent water meter continuously samples the current of the valve action process under no-load conditions and draws a current curve as shown in the figure. Figure 2 shown.

[0030] Depend on Figure 2 The curve shows that the current when the valve is in motion is highly correlated with the position of the mechanical actuator. In the startup phase, when the valve changes from a static state to a moving state, it needs to overcome a large mechanical friction force, and the drive current is large; after startup, the valve has the initial kinetic energy, the gear is in motion, and the drive current will become smaller. Figure 2 When the valve switch reaches the stroke limit, the gear will be blocked and the drive current will suddenly increase. Figure 2 The stalling stage. It can be seen that the driving current of the switch valve is variable, not constant. The sampled voltage value, the curve presented at the same time is inversely proportional to the current curve, which will not be repeated here.

[0031] The multiple groups of reduction gears in the water meter actuator are affected by the demolding time, temperature, and materials, and their dimensional tolerances, shapes, and hardness will be slightly different. Coupled with the tolerance of valve assembly, differences in the driving capabilities of electronic circuits, insufficient capacity of the power supply battery, and weak short-time discharge capabilities, these factors lead to failure phenomena such as valve failure to actuate, valve stuck, incomplete opening, loose closure, short duration, motion jams, and short-time reset of the MCU. These phenomena will be reflected in the driving current and voltage curves when the valve is actuated. It can be seen from this that it is not enough to determine the reliability of the valve system of the smart water meter with a single current threshold. This method cannot comprehensively and effectively screen a variety of potential fault types, and will cause products with quality risks to flow to the user side.

[0032] Next, continue to combine Figure 3-Figure 7 The specific contents of the present invention are described.

[0033] Figure 3 A flow chart of a method for detecting a smart water meter valve provided in an embodiment of the present invention includes steps S301-S303.

[0034] Step S301, obtaining the state of the water valve of the smart water meter; when the state of the water valve is open, adjusting the state of the water valve to a closed state, and when the state of the water valve is closed, adjusting the state of the water valve to an open state.

[0035] Under different working conditions, in addition to Figure 2 The current curve shown in the figure also has the following two characteristic conditions. When the water meter valve is under load, the current curves of opening and closing the valve are also different. The typical curves are as follows: Figure 4 , Figure 5 shown.

[0036] exist Figure 4 It can be seen from the curve that there is a big difference between the valve action stage and the no-load situation. After the start-up is completed, the current drops for a short time and then rises again. This is because after the valve is opened, the valve opening angle is small, and the resistance of the water pressure is relatively large, resulting in a larger required drive current; and when the valve opening angle reaches a certain position, part of the resistance is converted into power, causing the drive current to slowly drop again.

[0037] exist Figure 5 As can be seen from the curve, in the stage of valve action Figure 4 The curve is the opposite. After the start-up is completed, the current drops for a short time and then rises again. This is because after the valve is actuated, it is subject to the resistance of water pressure, which causes the required driving current to increase; and when the valve closing angle reaches a certain position, the resistance becomes greater and greater, causing the driving current to gradually increase.

[0038] Specifically, set the time interval ΔT for reading the voltage and current acquisition modules, such as setting the acquisition every 100ms. Theoretically, the smaller the setting time, the closer the collected data is to the true value curve. Through the communication line, send a command to read the position status of the tested smart water meter valve. Analyze the message returned by the tested water meter to determine the position of the water valve. If the valve is in the open state, send a close valve command; if it is in the closed state, execute the open valve command.

[0039] Step S302, during the state adjustment process of the water valve, obtaining the voltage change curve and the current change curve in the smart water meter.

[0040] Specifically, during the state adjustment process of the water valve, the values ​​of the voltage and current acquisition modules are read and recorded at the current time as T0. +nΔT (n = 1, 2, 3, ...), send a command to read the values ​​of the voltage and current acquisition modules. The voltage data is marked as , , ,……; the current data are marked as , , ,…….

[0041] By reading the valve position status information, it is determined whether the valve opening / closing action is completed. If not, data sampling continues; if completed, data sampling is performed. It is determined whether the valve state adjustment process has timed out. If not, data sampling continues; if timed out, data sampling is exited and the sampling data processing process is entered.

[0042] In the process of sampling data processing, the sampled current and voltage data are numbered in time sequence, all the data are distributed in sequence and drawn into a curve graph, and the data curves of current and voltage are synchronized with timestamps.

[0043] Step S303, acquiring characteristic parameters of the smart water meter according to the voltage change curve and the current change curve; and comparing the characteristic parameters with preset parameter thresholds to obtain detection results of the smart water meter.

[0044] In a possible implementation, in step S303, obtaining characteristic parameters of the smart water meter according to the voltage change curve and the current change curve includes: Step S3031, identifying the startup phase, the operation phase and the stall phase in the state adjustment process of the water valve according to the voltage change curve and the current change curve; Step S3032, according to the voltage change curve and the current change curve, obtain the characteristic parameters of the startup phase, the characteristic parameters of the operation phase and the characteristic parameters of the stall phase, and then obtain the characteristic parameters of the smart water meter.

[0045] set up Figure 2 The curve in is the standard mode of driving the valve current, and its startup phase is characterized by: 1. The current value rises rapidly from 0 to the peak current value , and then quickly drops to a stable normal driving current ; 2. The current rise time ΔTr is about 200ms, the fall time ΔTf is about 300ms, and the duration of the startup phase TS = 500ms.

[0046] 3. / The ratio R =4 is about.

[0047] According to the above characteristics, the corresponding threshold can be set to convert the current data , , , ...Use the sliding comparison method to compare the size of each pair one by one Ways to position , The position of the start-up phase is completed by segmenting the curve. Figure 2 The voltage data are marked as , , ,……; the current data are marked as , , ,…….

[0048] Sure After reaching the position, the subsequent stable operation stage is carried out. The slip comparison method is also used to determine the operation time and the turning point of entering the stall stage, so as to divide the curve interval of the operation stage, such as Figure 2 Finally, the curve is divided into the stall phase, and the position where the current is zero is set as the end time.

[0049] The curve is divided into the startup stage, the operation stage, and the stall stage. After the three-segment curve is calibrated, the corresponding voltage value curve is synchronized with the timestamp of the current data, and the voltage curve is processed in segments.

[0050] In a possible implementation manner, the characteristic parameters of the startup phase include: duration of the startup phase, peak current of the startup phase, and peak voltage of the startup phase.

[0051] In a possible implementation manner, the characteristic parameters of the operation phase include: duration of the operation phase, average operating current of the operation phase, and current data dispersion of the operation phase.

[0052] In a possible implementation manner, the characteristic parameters of the stall phase include: duration of the stall phase, a stall current during the stall phase, and a stall voltage during the stall phase.

[0053] In a possible implementation, step S303, comparing the characteristic parameter with a preset parameter threshold to obtain a detection result of the smart water meter, includes: Step S3033, comparing the characteristic parameters of the startup phase with the preset parameter thresholds, if the characteristic parameters of the startup phase meet the preset parameter threshold requirements, confirming that the detection result of the startup phase is qualified.

[0054] Specifically, the characteristic parameters of the startup phase include: the duration of the startup phase, the peak current of the startup phase, and the peak voltage of the startup phase.

[0055] Determine whether the duration of the startup phase is within the standard duration of the startup phase ±20%.

[0056] Determine whether the peak current in the startup phase is within the range of ±20% of the standard peak current in the startup phase.

[0057] Determine whether the vertex voltage during the startup phase is within the range of ±20% of the standard vertex voltage during the startup phase.

[0058] To determine that the test result is qualified, all three conditions mentioned above must be met, otherwise the cause of the problem needs to be further confirmed.

[0059] Step S3034, comparing the characteristic parameters of the operation phase with the preset parameter thresholds, if the characteristic parameters of the operation phase meet the preset parameter threshold requirements, confirming that the detection results of the operation phase are qualified.

[0060] Specifically, the characteristic parameters of the operation phase include: the duration of the operation phase, the average operating current of the operation phase, and the current data dispersion of the operation phase.

[0061] Determine whether the duration of the operating phase is within the standard duration of the operating phase ±20%.

[0062] Determine whether the average operating current during the operation phase is within the range of ±20% of the standard average operating current during the operation phase.

[0063] It is determined whether the current data dispersion during the operation phase is within the range of ±10% of the standard current data dispersion during the operation phase.

[0064] To determine that the test result is qualified, all three conditions mentioned above must be met, otherwise the cause of the problem needs to be further confirmed.

[0065] Step S3035, comparing the characteristic parameters of the stalled rotor stage with the preset parameter thresholds. If the characteristic parameters of the stalled rotor stage meet the preset parameter threshold requirements, it is confirmed that the detection result of the stalled rotor stage is qualified.

[0066] Specifically, the characteristic parameters of the stall phase include: the duration of the stall phase, the stall current of the stall phase and the stall voltage of the stall phase.

[0067] Determine whether the duration of the stall phase is within the standard duration of the stall phase ±20%.

[0068] Determine whether the locked-rotor current in the locked-rotor stage is within the range of ±20% of the standard locked-rotor current in the locked-rotor stage.

[0069] Determine whether the locked-rotor voltage in the locked-rotor stage is within the range of ±20% of the standard locked-rotor voltage in the locked-rotor stage.

[0070] To determine that the test result is qualified, all three conditions mentioned above must be met, otherwise the cause of the problem needs to be further confirmed.

[0071] Step S3036: If the test results of the startup phase, the operation phase, and the stall phase are all qualified, it is confirmed that the test results of the smart water meter are qualified.

[0072] When the detection result of any node in the startup phase, operation phase and stall phase is unqualified, the risk of the smart water meter is determined based on the characteristic parameters, and a risk warning message is sent to the user end. For details, please refer to the following embodiment.

[0073] In a possible implementation manner, the method for detecting a smart water meter valve further includes the steps of: If the detection result of the smart water meter is unqualified, a risk warning message will be sent to the user end based on the comparison result between the characteristic parameters and the preset parameter threshold.

[0074] In a possible implementation, an MCU short-time reset fault is identified based on a comparison result between a characteristic parameter and a preset parameter threshold.

[0075] Specifically, the value of the voltage curve is read. When the value of the voltage curve is less than the threshold of the MCU's operating voltage, it can be determined that the MCU is reset. For example, the minimum operating voltage of an MCU is 1.8V. When the test voltage curve is below 1.8V, the MCU is reset.

[0076] In a possible implementation manner, a fault of weak battery driving capability is identified based on a comparison result between the characteristic parameter and a preset parameter threshold.

[0077] Specifically, in the stall phase, when the driving current is the same, if the voltage value is seriously lower than the average voltage test value, the driving ability of the battery is weak.

[0078] In a possible implementation, the incomplete opening and closing fault of the smart water meter valve is identified based on the comparison result between the characteristic parameter and the preset parameter threshold.

[0079] Specifically, if the characteristics of the stalling phase are not identified in the current curve, or the duration of the stalling phase does not meet the standard value requirements, the characteristics of the stalling phase are not seen, indicating that the valve has mechanical defects and the limit switch may be faulty. If the characteristics of the stalling phase are not identified in the current curve, it may also be that there is a fault in the timing circuit of the smart water meter, the valve stroke ends prematurely before it is in place, and an effective action cycle is not formed, resulting in the lack of characteristics of the stalling phase.

[0080] In a possible implementation, a jamming fault is identified based on a comparison result between a characteristic parameter and a preset parameter threshold.

[0081] Specifically, the current curve in the motion phase has large periodic jumps. When a group of deceleration has a problem with the bite matching, the driving current will change greatly from the normal value. By observing the characteristics of the curve, this type of fault can be identified.

[0082] In the embodiment of the present invention, the test data can also be recorded and the test results with timestamps can be stored to realize the production test process data recording; the test data can be fitted to optimize the standard model curve.

[0083] The present invention can achieve the following beneficial effects by adopting the above method: 1. During the state adjustment process of the water valve, the voltage change curve and the current change curve in the smart water meter are obtained. The characteristic parameters of the smart water meter are obtained according to the voltage change curve and the current change curve; the characteristic parameters are compared with the preset parameter threshold to obtain the detection result of the smart water meter, which comprehensively and effectively reflects the working characteristics of the water meter valve and avoids the problem of low reliability of detecting the smart water meter valve through a single current threshold.

[0084] 2. After obtaining the detection result of the smart water meter by comparing the characteristic parameters with the preset parameter threshold, the present invention can issue a specific type of fault risk prompt to the user side when the detection result is unqualified, and can locate the location and type of the fault more accurately.

[0085] Figure 6 A schematic diagram of the structure of a detection device for a smart water meter valve provided by the present invention includes the following parts: A valve state control module is used to obtain the state of the water valve of the smart water meter; when the state of the water valve is in the open state, the state of the water valve is adjusted to the closed state, and when the state of the water valve is in the closed state, the state of the water valve is adjusted to the open state; A valve parameter identification module, used for obtaining a voltage change curve and a current change curve in the smart water meter during the state adjustment of the water valve; The valve detection module is used to obtain characteristic parameters of the smart water meter according to the voltage change curve and the current change curve; and compare the characteristic parameters with a preset parameter threshold to obtain a detection result of the smart water meter.
