However, the environmental conditions of different use positions in different use fields are different, so that a large and small use problem of many ultrasonic water meters may occur, for example, the problem that the ultrasonic water meter is easy to damage, and the problem that the detection of the ultrasonic water meter is not sensitive due to reasons such as poor sealing performance and poor heat resistance. The problem that a large number of ultrasonic water meters are easy to break is caused by poor pressure bearing performance of ultrasonic waves. Electronic components are installed in a base meter part of the ultrasonic water meter, the electronic components are influenced by water, the precision can be reduced, and the like, and if the ultrasonic water meter is damaged, the ultrasonic water meter cannot be used any more. Therefore, it is very important to detect the pressure bearing performance of the ultrasonic water meter.

Before most ultrasonic water meters are produced and put into use, workers simply check whether cracks and other macroscopic problems exist in all parts of the ultrasonic water meters, and if not, the ultrasonic water meters can be put into subsequent use. The detection mode can not detect the pressure bearing performance of the base meter in the ultrasonic water meter, and the pressure bearing performance of the ultrasonic water meter assembled by the base meter with uncertain pressure bearing performance is uncertain, so that the service life of the ultrasonic water meter is probably shortened due to poor pressure bearing performance when the ultrasonic water meter is put into subsequent use.

The test host can comprise a two-dimension code recognition device, and before the base table to be tested is placed into the pressure-bearing detection chamber, the two-dimension code recognition device is used for scanning the two-dimension code on the base table to be tested to obtain corresponding model information.

And S203, adjusting the pressure setting requirement according to the pressure bearing use requirement to obtain the test input parameters used in the test.

The test input parameters can be test parameters to be input when the pressure-bearing test is carried out, and the whole detection process is carried out according to the input test parameters.

In some implementations, specific content in the pressure-bearing use requirements can be compared with specific content in the pressure setting requirements to determine the requirements of the same type and the requirements of different types. For example, the demand to the base table that awaits measuring in the pressure-bearing user demand includes can bearing 1.3Mpa, and operating temperature generally is 7 degrees centigrade, and pressure needs rise to 1.3Mpa in 3 minutes, and the detection mode to the base table that awaits measuring in the pressure setting demand includes can bearing 1.5Mpa, and pressure needs rise to 1.5Mpa in 5 minutes, and pressure need pressurize 20min after pressure rises to 1.5Mpa, and pressure needs evenly promote. The same requirement of the type is that the pressure can be borne and the time for the pressure to rise to the required pressure, and the test input parameters can be added by taking the pressure to be borne and the time for the pressure to rise to the required pressure in the pressure-bearing use requirement as the standard, namely the pressure rises to 1.3MPa in 3 minutes. The different types of requirements, including dwell time, pressure rise and operating temperature, can now be added to the test input parameters. And obtaining the test input parameters used in the test based on the result.

In other implementations, the pressure setting requirement can be compared with the pressure-bearing use requirement, subject to a higher requirement. For example, when the default test pressure corresponding to the pressure setting requirement is smaller than the pressure corresponding to the pressure-bearing use requirement, the pressure corresponding to the pressure-bearing use requirement can be used as the test pressure in the test input parameters; when the default test temperature corresponding to the pressure setting requirement is less than the temperature corresponding to the pressure bearing use requirement, the temperature corresponding to the pressure bearing use requirement can be used as the test temperature in the test input parameter, and the like.

S204, obtaining the detection capacity of the pressure-bearing detection chamber, determining the type of a sealing gasket corresponding to the base meter to be detected and the displacement of the upper sealing clamp according to the type information of the base meter to be detected and the detection capacity, and determining the movement amount of the oil cylinder and the expansion amount of the piston rod of the oil cylinder according to the displacement of the upper sealing clamp.

The detection capacity can be the size of a space for placing a base table to be detected in the pressure-bearing detection chamber for detection, and can comprise length, width and height data, or the diameter and the height of the bottom surface and the like. The detection capacity can be a fixed parameter of the pressure-bearing detection chamber which is stored in a server in the control cabinet in advance. Because the base table to be detected has hollow positions, the hollow positions can be sealed by using corresponding sealing gaskets before detection. Meanwhile, the models of the base tables to be tested are different, and the corresponding sealing gasket models can be different. The sealing gasket is arranged on the upper sealing clamp, and the sealing gasket can be close to the base table to be tested and sealed through the displacement of the upper sealing clamp. The upper sealing clamp cannot move, and the upper sealing clamp can be connected with an oil cylinder through an oil cylinder piston rod, and the oil cylinder can provide moving force for the upper sealing clamp.

In some implementation modes, the oil cylinder and the oil cylinder piston pipe can move, the movable amount of the oil cylinder is small, and the telescopic amount of the oil cylinder piston pipe is large. When the upper sealing clamp is pushed to move, the oil cylinder and the oil cylinder piston pipe can move simultaneously.

Specifically, the model information of the base table to be measured includes data such as the height of the base table to be measured, and in order to seal completely, the upper sealing clamp needs to be moved to a degree capable of clamping the base table to be measured. Therefore, the gasket of which the model is used can be determined according to the model information of the base table to be tested. The data that the upper sealing clamp needs to move can be obtained according to the model information and the detection capacity of the base table to be detected. If the displacement of the upper sealing clamp is smaller, the oil cylinder can be controlled to move; if the displacement is great, can control the hydro-cylinder and remove mobilizable furthest, then control the flexible remaining distance of telescopic link.

S205, controlling the upper sealing clamp to replace a sealing gasket corresponding to the type of the sealing gasket, controlling the movement amount corresponding to the movement of the oil cylinder and the expansion amount corresponding to the expansion and contraction of the piston rod of the oil cylinder, pushing the upper sealing clamp to move by a distance corresponding to the displacement amount, and controlling the electric pressure test pump to inject pressure water into the pressure-bearing detection chamber through the hole according to test input parameters.

The pressurized water may be water injected in a high pressure manner. The upper sealing clamp can be provided with sealing gaskets of different types, and the sealing gaskets are arranged in parallel with the upper sealing clamp. When the sealing gasket is replaced, the sealing gasket can be rotated to the position where other sealing gaskets above are not shielded by taking the leftmost point of the sealing gasket as the center from the sealing gasket at the lowest part one by one until the sealing gasket with the corresponding model is selected, the sealing gasket with the corresponding model is moved to the lowest part, and the rotated sealing gasket is adjusted to the position above the sealing gasket and is rotated back to the original position, so that the replacement is completed.

Specifically, the upper sealing clamp is controlled to replace the sealing gasket corresponding to the type of the sealing gasket according to the mode, the oil cylinder and the oil cylinder piston rod are controlled to move simultaneously or sequentially to push the upper sealing clamp to move by a distance corresponding to the displacement, and the upper sealing clamp and the lower sealing clamp the base meter to be tested together. And controlling the electric pressure test pump to inject pressurized water into the pressure-bearing detection chamber through the hole according to the water delivery time, speed and the like in the test input parameters.

In some implementations, a robotic arm may be provided on the test mainframe for full automation purposes. The mechanical arm can move the base meter to be detected from the original storage position to the position for detection in the pressure-bearing detection chamber, and then subsequent clamping and other work are carried out.

And S206, when the electric pressure test pump begins to inject pressurized water into the pressure-bearing detection chamber, receiving pressure data detected by the pressure sensor in real time, and analyzing the pressure data to obtain a corresponding pressure-bearing detection result so as to determine whether the base table to be detected passes pressure-bearing detection or not.

When the electric pressure test pump begins to inject pressurized water into the pressure-bearing detection chamber, the pressurized water gradually fills the pressure-bearing detection chamber, the pressure gradually rises, and the pressure sensor in the hole can detect the change of the pressure.

In some implementations, a pressure transmitter may be connected between the test host and the control cabinet, and pressure data detected by the pressure sensor may be transmitted to the control cabinet via the pressure transmitter. The control cabinet can contain a display device such as a computer. After the pressure data is received, the control cabinet can process the data of the whole detection process according to the time when the pressure data is received, the receiving time and the data can be stored in a one-to-one correspondence mode, and the receiving time can also be used as an abscissa, and the corresponding pressure data can be used as an ordinate to create a change image. The input of the pressurized water can be set to be uniform, so that the change of the pressure data can rise according to a certain rule, and when the pressure data rises to the maximum pressure detected, the pressure data correspondingly keeps unchanged. If the pressure data fluctuates in size during the detection process, the pressure possibly changes due to poor sealing performance; if the pressure data suddenly decreases, pressure relief may occur due to pressure bearing problems, rupture, and the like. This may indicate failure of the pressure bearing detection.

It should be noted that, the data mentioned in the above embodiments are only examples, and do not limit the method provided in the present application.

Then obtain the model information of the base table that awaits measuring, confirm the pressure-bearing user demand of the base table that awaits measuring that has this type information according to the model information to confirm when actually putting into use, service environment is to the pressure-bearing requirement of this base table that awaits measuring. And then, adjusting the default pressure-bearing requirement according to the pressure-bearing requirement of the base table to be tested on the use environment, and determining the test input parameter for carrying out the pressure-bearing detection, wherein the pressure-bearing requirement corresponding to the test input parameter is higher than the pressure-bearing requirement when the base table to be tested is put into actual work. According to the model information of the base meter to be detected, the model of the sealing gasket and the displacement of the upper sealing clamp used by the base meter to be detected during pressure bearing detection can be determined, and the movement amount of the oil cylinder and the expansion amount of the piston rod of the oil cylinder can be further determined according to the displacement of the upper sealing clamp, so that the actual movement condition of the upper sealing clamp in the detection process is clearer. And then the upper sealing clamp, the oil cylinder piston rod and the electric pressure test pump can be controlled to carry out corresponding work according to the determined various information. And meanwhile, when the electric pressure test pump starts to inject pressurized water into the pressure-bearing detection chamber, pressure data detected by the pressure sensor is received in real time, and the pressure data is analyzed to obtain a corresponding pressure-bearing detection result. This embodiment carries out the detection of bearing capacity to the basic table that awaits measuring of ultrasonic water meter, and whole process is accomplished automatically in the information interaction of switch board and experimental host computer, can determine the bearing capacity of the basic table that awaits measuring according to the pressure-bearing testing result, and then determines the bearing capacity of the ultrasonic water meter who assembles by this basic table that awaits measuring, prolongs the life of this ultrasonic water meter in actual work.

In some embodiments, the test input parameters include a test pressure, a test water injection frequency, a dwell time to maintain the test pressure, and a test temperature. The obtaining of the model information of the base table to be tested and the determining of the pressure-bearing use requirement of the base table to be tested according to the model information may specifically include: obtaining model information of a base table to be tested, and determining an application area of the base table according to the model information; acquiring historical water level depth, historical base meter installation position, historical temperature, water pressure change frequency and historical water flow speed of an application area; and determining the pressure-bearing use requirement of the base meter to be tested according to the historical water level depth, the historical base meter installation position, the historical temperature, the water pressure change frequency and the historical water flow speed, wherein the pressure-bearing use requirement comprises a water pressure requirement, a temperature requirement and a water injection frequency requirement.

The test pressure may be the highest pressure to be borne by the base table to be tested in the above embodiment, the time for holding under the test pressure may be the corresponding pressure holding time, and the temperature during the test may be the test temperature. The water injection frequency can be the water injection speed which can reach the test pressure within the required time when pressurized water is uniformly injected in the test process. The application area can be an area which can be used by the base table to be tested after being produced. The historical water level depth may be the depth of the water level at the location where the application area used the ultrasonic water meter in the past, and may comprise a plurality of depths. The historical base meter installation position may be a position at which the ultrasonic water meter is installed when the ultrasonic water meter is used in the past, and a position below the water level line when the ultrasonic water meter starts to operate. The historical temperature may be the ambient temperature at which the ultrasonic water meter has been operating in the past. The historical water flow speed may be a water flow speed corresponding to different times when the ultrasonic water meter operates in the past. In the past when ultrasonic water meters were operating, the water flow rate could have increased or decreased to another rate during each period of time, and the frequency of the change in water pressure could be the frequency of this change.

Specifically, the model information of the base table to be measured is obtained in reference to step S202, information related to the application area of the base table to be measured is extracted from the model information, and the corresponding application area is determined.

In some implementation manners, the information related to the application area in the model information may carry the historical water level depth, the historical base table installation position, the historical temperature, the water pressure change frequency, and the historical water flow speed of the application area, and these information may be directly extracted. According to the historical water level depth and the historical base meter installation position of the application area, the maximum pressure to be born by the base meter to be tested, namely the water pressure requirement, can be determined. According to the historical water pressure change frequency and the historical water flow speed, the water flow speed of the ultrasonic water meter to be tested can be obtained, and the water flow speed of the ultrasonic water meter to be tested needs to be borne, so that the water injection frequency requirement that water is injected according to the frequency can be determined when a pressure bearing test is carried out. According to the historical temperature of the application area, the temperature requirement, namely the temperature range within which the ultrasonic water meter assembled by the base table to be tested needs to work, can be obtained. And obtaining the pressure-bearing use requirement of the base table to be tested based on the above.

In other implementations, relevant information about the application area may be looked up on the internet, along with information about the application area in the model information, as a source of information about historical water level depth, historical base table installation location, historical temperature, water pressure change frequency, and historical water flow rate. Meanwhile, the information related to the application area in the model information can be updated.

The application area of the base meter to be tested can be determined according to the acquired model information, the requirements which need to be met by the base meter to be tested and corresponding to the ultrasonic water meter working under the application area are obtained by acquiring the information of the historical water level depth, the historical base meter installation position, the historical temperature, the water pressure change frequency and the historical water flow speed of the application area, so that the pressure-bearing service requirement of the base meter to be tested is more accurate and is more matched with the environment requirement in the actual working process.

In some embodiments, the test input parameter comprises a pressure bearing test time. When the electric pressure test pump begins to inject pressurized water into the pressure-bearing detection chamber, the pressure data detected by the pressure sensor is received in real time, and the pressure data is analyzed to obtain a corresponding pressure-bearing detection result, so as to determine whether the base table to be detected passes through pressure-bearing detection, and the method specifically comprises the following steps: when the electric pressure test pump starts to inject pressurized water into the pressure-bearing detection chamber, pressure data detected by the pressure sensor are received in real time, wherein the pressure data comprise the current time and a current pressure value corresponding to the current time; generating a corresponding test pressure graph according to the current time and the current pressure value; acquiring a corresponding preset pressure effect diagram according to the test input parameters; judging whether the pressure data corresponding to the test pressure diagram is the same as the pressure data corresponding to the preset pressure effect diagram at the current moment; if the pressure values are different, determining the pressure difference value of the pressure value corresponding to the test pressure diagram and the pressure value corresponding to the preset pressure effect diagram at the current moment, wherein the pressure-bearing detection result at the current moment is that the base table to be detected does not pass the pressure detection; if the pressure values are the same, determining whether to continue detection or not according to the current time and the pressure-bearing test time, wherein the pressure-bearing detection result of the current time is that the base meter to be detected passes the pressure detection;

the method may further include: and if the pressure value corresponding to the test pressure diagram is different from the pressure value corresponding to the preset pressure effect diagram at the current moment, determining the reason that the base table to be detected fails to pass the pressure detection according to the pressure difference value and the fluctuation range of the first preset difference value.

The pressure-bearing test time may be the entire time from the start of water injection to the end of the pressure-holding time. The pressure data may include the time at which the pressure data was transmitted and the specific pressure value generated at that time. The received pressure values may be the current time and the current pressure value corresponding to the current time. The first preset difference fluctuation range may include a broken difference fluctuation range and a poor sealability difference fluctuation range. When the breakage occurs, the pressure value may drop sharply, and when the sealability is poor, the pressure value may drop slowly. For example, if the pressure difference is 0-5kpa, the fluctuation range of the difference corresponding to poor sealing performance; if the pressure difference is 5kpa-1Mpa, the fluctuation range of the difference corresponding to the damage is determined.

The preset pressure effect graph can be an effect graph which is normally displayed when the pressure-bearing detection of the base meter to be detected is passed according to any test input parameter to carry out pressure-bearing test on the base meter to be detected. The control cabinet may include a server and the preset pressure effect map may be stored in the server of the control cabinet. In some implementations, the generated pressure value may increase according to a certain rule as the time for injecting pressurized water elapses, a straight line with a certain slope may be displayed on the preset pressure effect diagram, and a straight line parallel to the abscissa axis is correspondingly displayed after the pressure value increases to the maximum pressure value.

Specifically, when the electric pressure test pump begins to inject pressurized water into the pressure-bearing detection chamber, the pressure sensor can transmit pressure data to the control cabinet. The control cabinet may include a computer or other display device, and the coordinate system is generated by using the current time when the pressure data is received as an abscissa and using the current pressure value corresponding to the current time as an ordinate. And displaying the pressure data of the current moment on the coordinate system, wherein the pressure value of each moment can be displayed as a corresponding point on the coordinate system, and connecting the points of each moment to generate a test pressure graph. And calling a corresponding preset pressure effect diagram in a server in the control cabinet according to the used test input parameters. Whether the pressure data corresponding to the test pressure diagram is the same as the pressure data corresponding to the preset pressure effect diagram at the current moment or not can be checked, if yes, whether the current moment is the termination moment of the pressure-bearing test time or not can be checked, if yes, the detection can be stopped, and at the moment, the fact that the base table to be detected passes the pressure detection can be indicated; if the ending time is not reached, the detection can be continued, and at the moment, the fact that the base meter to be detected passes the pressure detection at the current time can be shown, but the whole pressure bearing detection is not finished yet. If the pressure detection result is not the same, the pressure detection result at the current moment can be represented to correspond to the result that the base table to be detected does not pass the pressure detection. The pressure value corresponding to the test pressure diagram and the pressure value corresponding to the preset pressure effect diagram can be subtracted to obtain a corresponding pressure difference value. At this time, the pressure difference value may be compared with the pressure value within the first preset difference value fluctuation range, and the reason why the pressure detection is not passed may be determined.

In other implementations, the reason for failing to detect the pressure may also be determined according to the variation of the curve on the preset pressure effect graph.

It should be noted that, in the above embodiments, the reference to the data is only an example, and does not limit the method provided by the present application.

In this embodiment, a test pressure map may be generated according to the pressure data received in real time, and through comparison between the test pressure map and the pressure value corresponding to the preset pressure effect map at the current time, it may be determined whether the detection result of the base table to be detected at the current time passes or fails. If the pressure difference value does not pass through, the pressure difference value can be compared with the pressure value in the first preset difference value fluctuation range, and the reason why the pressure difference value does not pass through is determined. The detection process is monitored in real time, if abnormity occurs, the abnormity can be found in time, and the bearing detection efficiency is improved.

The method may further include: and if the pressure-bearing detection result at the current moment is that the base meter to be detected does not pass the pressure detection, controlling the electric pressure test pump to open the pressure release valve and give an alarm to stop the pressure-bearing detection.

Specifically, if the pressure-bearing detection result at the current moment is that the base meter to be detected does not pass the pressure detection, it can be indicated that the base meter to be detected is damaged or the sealing performance is not good. However, no matter what kind of situation, the base meter to be detected can be represented to be incapable of continuing to detect, and at the moment, the electric pressure test pump is controlled to open the pressure release valve, so that the pressure in the pressure-bearing detection chamber is gradually reduced, and meanwhile, the alarm can be given.

In other implementation modes, a flashing lamp can be installed on the test host, and the alarm can be given by controlling the flashing lamp to flash light with different colors.

And then directly calling the detection capacity and the reserved volume of the pressure-bearing detection chamber from the server. And subtracting the reserved volume from the detection capacity to obtain the space volume for placing the base meter to be detected, and determining how many base meters to be detected can be placed in the pressure-bearing detection chamber based on the volume data of the base meters to be detected.

The image acquisition device may be a device for capturing, recording, such as a camera, video camera, etc. The image data may be image data acquired by the image acquisition device from the beginning of the water filling. The preset time period may be preset, and is used for analyzing a time period of image interception which does not pass the reason of pressure bearing detection, and a time period corresponding to 3 minutes before the current time may be selected. When the base tables to be detected are detected in batches, if the base tables to be detected do not pass pressure-bearing detection through comparison of the test pressure diagram and the preset pressure effect diagram, the base tables to be detected have problems with a certain base table or a plurality of base tables to be detected with high probability, and the base tables with poor sealing performance or damaged can be used as problem base tables.
