Description

Technical Field

[0001] The invention relates to the field of electromagnetic valve testing, and in particular to a method and system for testing the operation transition of a water electromagnetic valve. Background Art

[0002] The water solenoid valve is installed in the water pipe and is used to adjust the water flow and / or divert the water flow. By applying the corresponding current signal, the valve opening state inside the water solenoid valve can be changed. When the water solenoid valve repeatedly opens and closes the valve after a long period of operation, the electronic components inside the water solenoid valve will be damaged, making it impossible for the water solenoid valve to perform valve action in time under the action of the corresponding current signal, causing the water solenoid valve to relax. In addition, water solenoid valves have a certain working life. When the number of times the water solenoid valve repeatedly performs valve opening and closing actions reaches a certain level, the water solenoid valve will not be able to normally adjust the water flow and / or divert the water flow. In order to test the working life and working performance of the water solenoid valve, it is necessary to conduct a comprehensive and accurate operating performance test on the water solenoid valve.

[0059] The beneficial effects of the above embodiments are that the water solenoid valve operation transition test method obtains the first water flow state information and the second water flow state information of the associated pipeline area in the test water pipe pipeline when the water solenoid valve is not in operation and in the corresponding operation mode, so as to quantitatively identify the water flow regulation effect of the water solenoid valve in the pipeline; then the first water flow state information and the second water flow state information are compared to determine whether an abnormal event occurs in the operation mode execution of the water solenoid valve, so as to determine the working limit conditions of the water solenoid valve in the current operation mode, thereby accurately determining the extreme water flow regulation conditions of the water solenoid valve; and also obtains the second water flow state change information corresponding to the repeated operation switching of the water solenoid valve under the said working limit conditions, so as to determine the working parameter information corresponding to the working failure event of the water solenoid valve under the said working limit conditions, and accurately test the working performance and life of the water solenoid valve.

[0060] In another embodiment, obtaining first water flow state information of an associated pipeline area in a test water pipeline when the water solenoid valve is not in operation, and obtaining second water flow state information of an associated pipeline area in the test water pipeline when the water solenoid valve is in a corresponding operation mode, includes:

[0061] Acquire first water flow state information corresponding to a downstream pipeline area of ​​a test water pipeline where the water solenoid valve is in a fully open state; wherein the first water flow state information includes water flow rate information;

[0062] Acquire the second water flow state information corresponding to the downstream pipeline area of ​​the test water pipeline where the water solenoid valve is located in the corresponding water diversion operation mode; wherein the second water flow state information includes water flow rate information;

[0063] The first water flow state information and the second water flow state information are respectively subjected to identification processing regarding the extension direction along the downstream pipeline.

[0064] The beneficial effect of the above embodiment is that during the test of the water solenoid valve, the water solenoid valve is installed in the test water pipe, so that the water solenoid valve can divert the water flow at the upstream position in the test water pipe, thereby dividing the upstream water flow into several downstream water flows, and at this time, the solenoid valve components inside the water solenoid valve will perform corresponding actions to realize the diversion of the water flow. Accordingly, the first water flow state information corresponding to the downstream pipeline area where the water solenoid valve is located in the fully open state of the test water pipe is obtained, and the second water flow state information corresponding to the downstream pipeline area where the water solenoid valve is located in the corresponding water diversion operation mode is obtained, so that the water flow state of the upstream and downstream areas of the water solenoid valve can be quantitatively identified, and the first water flow state information and the second water flow state information are respectively marked along the extension direction of the downstream pipeline, so as to provide a reliable basis for the subsequent identification of the water flow diversion adjustment state of the water solenoid valve.

[0065] In another embodiment, the first water flow state information and the second water flow state information are respectively subjected to identification processing in terms of the extension direction of the downstream pipeline, including:

[0066] Step S1, using the following formula (1), according to the information states of the first water flow state information and the second water flow state information, unify the information type of the unit direction vector along the extension direction of the downstream pipeline,

[0067]

[0068] In the above formula (1), N1 represents the data after the information type of the unit direction vector corresponding to the first water flow state information along the extension direction of the downstream pipeline is unified; D1 represents the first water flow state information; s(D1) represents the information type of the first water flow state information; (X1, Y1, Z1) represents the unit direction vector corresponding to the first water flow state information along the extension direction of the downstream pipeline; [] s(D1) Indicates that the data in the brackets are converted to data of type s(D1); N2 indicates the data after the information type is unified for the unit direction vector corresponding to the second water flow state information along the extension direction of the downstream pipeline; D2 indicates the second water flow state information; s(D2) indicates the information type of the second water flow state information; (X2, Y2, Z2) indicates the unit direction vector corresponding to the second water flow state information along the extension direction of the downstream pipeline; [] s(D2) Indicates that the data in the brackets is converted to s(D2) type data; ASCII"" means that the data in the double quotes is converted to ASCII code format;

[0069] Step S2, using the following formula (2), the first water flow state information and the second water flow state information are calibrated with special character data,

[0070]

[0071] In the above formula (2), D1′ represents the first water flow state information after the special character data is calibrated; D2′ represents the second water flow state information after the special character data is calibrated; len{} represents the total number of data bits in the brackets; @ represents a special character; << represents a left shift symbol;

[0072] Step S3, using the following formula (3), the first water flow state information and the second water flow state information after the special character data calibration are respectively processed with respect to the extension direction of the downstream pipeline.

[0073]

[0074] In the above formula (3), d1 represents the data after the first water flow state information after special character data calibration is processed with respect to the extension direction of the downstream pipeline; d2 represents the data after the second water flow state information after special character data calibration is processed with respect to the extension direction of the downstream pipeline.

[0075] The beneficial effect of the above embodiment is that, by using the above formula (1), according to the information status of the first water flow state information and the second water flow state information, the information type of the unit direction vector along the extension direction of the downstream pipeline is unified, so that the data type is unified to facilitate subsequent data calibration; then, by using the above formula (2), the first water flow state information and the second water flow state information are calibrated with special character data, which can distinguish between direction and information, and adding special characters can also enhance the security of the data itself; then, by using the above formula (3), the first water flow state information and the second water flow state information after the special character data calibration are respectively marked with identification processing along the extension direction of the downstream pipeline, and then the data calibration is automatically completed, which reflects the intelligence of the system.

[0076] In another embodiment, the first water flow state information and the second water flow state information are compared to obtain first water flow state change information of the associated pipeline area; based on the first water flow state change information, it is determined whether an abnormal event occurs in the working mode execution of the water solenoid valve; when an abnormal event occurs in the working mode execution of the water solenoid valve, the working limit condition of the water solenoid valve in the current working mode is determined, including:

[0077] The first water flow state information is compared with the second water flow state information to obtain first water flow change information of all downstream pipelines included in the downstream pipeline area; based on the first water flow change information, a water flow drift value of each downstream pipeline is obtained; if the water flow drift values ​​of all downstream pipelines are less than a preset drift threshold, it is determined that no abnormal operation mode execution event occurs in the water solenoid valve; otherwise, it is determined that an abnormal operation mode execution event occurs in the water solenoid valve;

[0078] When an abnormal event occurs in the working mode execution of the water solenoid valve, it is determined that when the water flow drift value first occurs in all downstream pipelines during the water diversion operation of the water solenoid valve and is greater than or equal to the preset drift threshold, the driving current applied to the water solenoid valve in real time is used as the working limit condition of the water solenoid valve in the water diversion operation mode.

[0079] The beneficial effect of the above embodiment is that the first water flow state information and the second water flow state information respectively represent the water flow conditions of the water solenoid valve in the upstream and downstream of the test water pipe. The first water flow state information and the second water flow state information are compared to obtain the first water flow change information of all downstream pipes contained in the downstream pipe area, so that the water flow change of the diverted water flow of all downstream pipes by the water solenoid valve can be quantitatively identified. Based on the analysis of the first water flow change information, the water flow drift value of each downstream pipe is obtained, so that the water flow diversion stability of each downstream pipe by the water solenoid valve can be quantitatively determined. The larger the water flow drift value of the downstream pipe, the smaller the water flow diversion stability of the water solenoid valve to the corresponding downstream pipe. The water flow drift value of each downstream pipe is compared with the preset drift threshold value to determine whether the water solenoid valve has an abnormal operation mode execution event. When the water solenoid valve has an abnormal operation mode execution event, it is determined that when the water flow rate drift value of all downstream pipelines of the water solenoid valve is greater than or equal to the preset drift threshold value, the driving current applied to the water solenoid valve in real time, that is, if the driving current applied to the water solenoid valve when the water flow rate deviation value of any one of all downstream pipelines is greater than or equal to the preset drift threshold value, indicates that the driving current currently applied to the water solenoid valve has reached the acceptable limit current of the water solenoid valve, and if the driving current applied to the water solenoid valve continues to increase, the diversion effect of the water solenoid valve will deteriorate. Using the driving current applied to the water solenoid valve in real time as the working limit condition of the water solenoid valve in the water diversion operation mode, it can provide corresponding test conditions for subsequent repeated testing of the water solenoid valve under working limit conditions.

[0080] In another embodiment, obtaining second water flow state change information corresponding to repeated working switching of the water solenoid valve under the working limit condition, and determining working parameter information corresponding to a working failure event of the water solenoid valve under the working limit condition based on the second water flow state change information, includes:

[0081] Acquire the second water flow state change information of the downstream pipeline area during the process of repeatedly switching the water solenoid valve from the fully open state to the corresponding water diversion operation mode under the condition that the driving current is applied to the water solenoid valve; wherein the second water flow state change information includes the response time of the water flow change in the downstream pipeline area;

[0082] The response time is compared with a preset time threshold; if the response time is greater than the preset time threshold, it is determined that a working failure event occurs in the water solenoid valve under the condition that the driving current is applied; otherwise, it is determined that no working failure event occurs in the water solenoid valve under the condition that the driving current is applied; the number of repeated switchings corresponding to the water solenoid valve repeatedly switching from a fully open state to a corresponding water diversion operation mode before sending a working failure event is obtained, and this is used as the maximum number of switching operations corresponding to the water solenoid valve triggering a working failure event.

[0083] The beneficial effect of the above embodiment is that, based on the above determined driving current, the water solenoid valve is repeatedly switched from the two states of never applying any driving current and applying the above determined driving current, so that the water solenoid valve is repeatedly switched from the fully open state to the corresponding water diversion operation mode, and in the repeated switching process, the second water flow state change information of the downstream pipeline area of ​​the water solenoid valve is obtained, that is, the response time of the water flow change in the downstream pipeline area, so that the response speed of the water solenoid valve to the corresponding water flow adjustment under the action of the driving current can be quantitatively determined. Then the response time is compared with the preset time threshold to determine whether the water solenoid valve has a working failure event. The number of repeated switchings corresponding to the repeated switching from the fully open state to the corresponding water diversion operation mode before the water solenoid valve sends a working failure event is also obtained, so that the maximum number of switching actions allowed by the water solenoid valve can be accurately determined, thereby accurately testing the working life of the water solenoid valve.

[0095] The beneficial effect of the above embodiment is that during the test of the water solenoid valve, the water solenoid valve is installed in the test water pipe, so that the water solenoid valve can divert the water flow at the upstream position in the test water pipe, thereby dividing the upstream water flow into several downstream water flows, and at this time, the solenoid valve components inside the water solenoid valve will perform corresponding actions to realize the diversion of the water flow. Accordingly, the first water flow state information corresponding to the downstream pipeline area where the water solenoid valve is located in the fully open state of the test water pipe is obtained, and the second water flow state information corresponding to the downstream pipeline area where the water solenoid valve is located in the corresponding water diversion operation mode is obtained, so that the water flow state of the upstream and downstream areas of the water solenoid valve can be quantitatively identified, and the first water flow state information and the second water flow state information are respectively marked along the extension direction of the downstream pipeline, so as to provide a reliable basis for the subsequent identification of the water flow diversion adjustment state of the water solenoid valve.

[0096] In another embodiment, the electromagnetic valve working abnormality judgment module is used to compare the first water flow state information with the second water flow state information to obtain the first water flow state change information of the associated pipeline area; based on the first water flow state change information, judging whether the water electromagnetic valve has an abnormal working mode execution event, including:

[0097] The first water flow state information is compared with the second water flow state information to obtain first water flow change information of all downstream pipelines included in the downstream pipeline area; based on the first water flow change information, a water flow drift value of each downstream pipeline is obtained; if the water flow drift values ​​of all downstream pipelines are less than a preset drift threshold, it is determined that no abnormal operation mode execution event occurs in the water solenoid valve; otherwise, it is determined that an abnormal operation mode execution event occurs in the water solenoid valve;

[0098] The solenoid valve working limit determination module is used to determine the working limit condition of the water solenoid valve under the current working mode when an abnormal event occurs in the working mode execution of the water solenoid valve, including:

[0099] When an abnormal event occurs in the working mode execution of the water solenoid valve, it is determined that when the water flow drift value first occurs in all downstream pipelines during the water diversion operation of the water solenoid valve and is greater than or equal to the preset drift threshold, the driving current applied to the water solenoid valve in real time is used as the working limit condition of the water solenoid valve in the water diversion operation mode.

[0100] The beneficial effect of the above embodiment is that the first water flow state information and the second water flow state information respectively represent the water flow conditions of the water solenoid valve in the upstream and downstream of the test water pipe. The first water flow state information and the second water flow state information are compared to obtain the first water flow change information of all downstream pipes contained in the downstream pipe area, so that the water flow change of the diverted water flow of all downstream pipes by the water solenoid valve can be quantitatively identified. Based on the analysis of the first water flow change information, the water flow drift value of each downstream pipe is obtained, so that the water flow diversion stability of each downstream pipe by the water solenoid valve can be quantitatively determined. The larger the water flow drift value of the downstream pipe, the smaller the water flow diversion stability of the water solenoid valve to the corresponding downstream pipe. The water flow drift value of each downstream pipe is compared with the preset drift threshold value to determine whether the water solenoid valve has an abnormal operation mode execution event. When the water solenoid valve has an abnormal operation mode execution event, it is determined that when the water flow rate drift value of all downstream pipelines of the water solenoid valve is greater than or equal to the preset drift threshold value, the driving current applied to the water solenoid valve in real time, that is, if the driving current applied to the water solenoid valve when the water flow rate deviation value of any one of all downstream pipelines is greater than or equal to the preset drift threshold value, indicates that the driving current currently applied to the water solenoid valve has reached the acceptable limit current of the water solenoid valve, and if the driving current applied to the water solenoid valve continues to increase, the diversion effect of the water solenoid valve will deteriorate. Using the driving current applied to the water solenoid valve in real time as the working limit condition of the water solenoid valve in the water diversion operation mode, it can provide corresponding test conditions for subsequent repeated testing of the water solenoid valve under working limit conditions.

[0101] In another embodiment, the water flow state change information acquisition module is used to acquire the second water flow state change information corresponding to the repeated working switching of the water solenoid valve under the working limit condition, including:

[0102] Acquire the second water flow state change information of the downstream pipeline area during the process of repeatedly switching the water solenoid valve from the fully open state to the corresponding water diversion operation mode under the condition that the driving current is applied to the water solenoid valve; wherein the second water flow state change information includes the response time of the water flow change in the downstream pipeline area;

[0103] The solenoid valve failure identification module is used to determine the working parameter information corresponding to the working failure event of the water solenoid valve under the working limit condition based on the second water flow state change information, including:

[0104] The response time is compared with a preset time threshold; if the response time is greater than the preset time threshold, it is determined that a working failure event occurs in the water solenoid valve under the condition that the driving current is applied; otherwise, it is determined that no working failure event occurs in the water solenoid valve under the condition that the driving current is applied; the number of repeated switchings corresponding to the water solenoid valve repeatedly switching from a fully open state to a corresponding water diversion operation mode before sending a working failure event is obtained, and this is used as the maximum number of switching operations corresponding to the water solenoid valve triggering a working failure event.

[0105] The beneficial effect of the above embodiment is that, based on the above determined driving current, the water solenoid valve is repeatedly switched from the two states of never applying any driving current and applying the above determined driving current, so that the water solenoid valve is repeatedly switched from the fully open state to the corresponding water diversion operation mode, and in the repeated switching process, the second water flow state change information of the downstream pipeline area of ​​the water solenoid valve is obtained, that is, the response time of the water flow change in the downstream pipeline area, so that the response speed of the water solenoid valve to the corresponding water flow adjustment under the action of the driving current can be quantitatively determined. Then the response time is compared with the preset time threshold to determine whether the water solenoid valve has a working failure event. The number of repeated switchings corresponding to the repeated switching from the fully open state to the corresponding water diversion operation mode before the water solenoid valve sends a working failure event is also obtained, so that the maximum number of switching actions allowed by the water solenoid valve can be accurately determined, thereby accurately testing the working life of the water solenoid valve.

[0106] In general, the water solenoid valve operation transition test method and system obtain the first water flow state information and the second water flow state information of the associated pipeline area in the test water pipe pipeline when the water solenoid valve is not in operation and in the corresponding operation mode, so as to quantitatively identify the water flow regulation effect of the water solenoid valve in the pipeline; then compare the first water flow state information and the second water flow state information to determine whether the water solenoid valve has an abnormal operation mode execution event, so as to determine the working limit conditions of the water solenoid valve in the current working mode, so as to accurately determine the extreme water flow regulation conditions of the water solenoid valve; also obtain the second water flow state change information corresponding to the repeated working switching of the water solenoid valve under the said working limit conditions, so as to determine the working parameter information corresponding to the working failure event of the water solenoid valve under the said working limit conditions, and accurately test the working performance and life of the water solenoid valve.
