Description

Technical Field

[0001] The present application relates to the technical field of lock valve calibration, and in particular to a method, device, system and equipment for automatic calibration of a lock valve distance of an oil unloading valve. Background Art

[0002] The API unloading valve is a liquid valve, the valve face and the valve core are rigidly connected, that is, the distance between the valve face and the valve core is fixed. When the valve stem is moved, the valve face and the valve core will keep moving in the same direction and distance. If the valve core is supported to prevent it from moving, it is equivalent to ensuring that the position of the valve face remains unchanged. The existing lock schemes are based on this principle, using the lock rod to support the valve core to fix the valve core and the valve face. The existing technology can only ensure that the valve core is supported and some pre-tightening force is applied. If the position of the valve core is correctly closed at the moment of support, the valve face is flat, and the liquid cannot flow through, then the closed state of the valve can be guaranteed before subsequent actions; but if the position of the valve core is not correctly closed when it is supported, the valve face is not flat, and the liquid can flow through, but the existing technology and products cannot sense the closed state of the valve core and will misjudge that the valve is closed.

[0003] That is, the prior art only performs the locking action, but cannot accurately detect whether it is tightly closed. For liquid valves, a gap exceeding 1 mm may allow liquid to flow through (depending on the elasticity of the valve rubber ring), which greatly reduces the effect of the lock and may cause oil leakage. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a method, device, system and equipment for automatic calibration of the valve lock distance of an oil unloading valve, so as to solve the problem that the existing oil unloading valve cannot detect whether the valve core is tightly closed, which may cause oil leakage.

[0005] In a first aspect, an embodiment of the present application provides a method for automatically calibrating a locking valve distance of an oil unloading valve, which is applied to an oil unloading valve locking system, wherein the oil unloading valve locking system comprises: a motor module, a screw module, an oil unloading valve and a main board inside the lock, wherein the motor module comprises an encoder, a motor and a reducer, and the method comprises:

[0006] When the switch lock of the oil unloading valve is installed for the first time, receive the calibration instructions;

[0007] According to the calibration instructions, the calibration process is automatically executed to obtain several stroke values;

[0008] If the stroke value satisfies the set non-discrete algorithm, the average value of several stroke values ​​is taken as the calibration value and stored on the main board inside the lock;

[0009] If the stroke value does not meet the set non-discrete algorithm, it will prompt that the calibration has failed;

[0010] When the calibration is completed, the calibration value is stored;

[0011] When receiving the unsealing / sealing instruction, the current stroke value is obtained and the current stroke value is compared with the calibration value;

[0012] If the difference between the current stroke value and the calibration value is less than the first set threshold, it is determined that the unsealing / sealing instruction is correct and the current unsealing / sealing is normal;

[0013] If the difference between the current stroke value and the calibration value is greater than the first set threshold, an over-long alarm or a too-short alarm is prompted according to the difference.

[0014] In the above implementation process, when the switch lock of the oil unloading valve is installed for the first time, a calibration instruction is received; according to the calibration instruction, the calibration process is automatically executed to obtain several stroke values; if the stroke value satisfies the set non-discrete algorithm, the average value of several stroke values ​​is taken as the calibration value and stored on the main board in the lock; if the stroke value does not satisfy the set non-discrete algorithm, it is prompted that the calibration failed; when the calibration is completed, the calibration value is stored; when the execution unsealing / sealing instruction is received, the current stroke value is obtained, and the current stroke value is compared with the calibration value; if the difference between the current stroke value and the calibration value is less than the first set threshold value, it is determined that the unsealing / sealing instruction is correct and the unsealing / sealing is normal this time; if the difference between the current stroke value and the calibration value is greater than the first set threshold value, an overlong alarm or a too short alarm is prompted according to the difference; the automatic calibration algorithm can be used for different valve lock distances, and the calibration value that passes the calibration is a reliable valve closed mark, which can be used as a standard for whether the subsequent switch lock is in place, and the oil leakage problem caused by false lock is eliminated.

[0015] Furthermore, the calibration process is automatically executed according to the calibration instruction to obtain several stroke values, including:

[0016] When the main board in the lock receives the calibration instruction, it automatically executes the calibration process according to the calibration instruction, repeatedly executes the sealing action setting group, and each group will obtain two stroke values, and obtain several stroke values; among which, the stroke value represents the movable distance of the screw rod between the current lock and the valve.

[0017] In the above implementation process, the stroke value is obtained so as to determine the calibration according to the stroke value.

[0018] Furthermore, the travel value does not satisfy the set non-discrete algorithm, including:

[0019] Taking the median value of the stroke value sequence, calculating the mathematical mean difference of the stroke values, if the mathematical mean difference of the stroke values ​​is greater than or equal to the second set threshold, determining that the stroke value does not satisfy the set non-discrete algorithm;

[0020] The travel value satisfies the set non-discrete algorithm, including:

[0021] If the mathematical mean difference of the stroke values ​​is less than the second set threshold, it is determined that the stroke values ​​meet the set non-discrete algorithm.

[0022] In the above implementation process, whether the stroke value satisfies the non-discrete algorithm is used to determine whether it complies with the calibration process, thereby detecting whether the valve core is tightly closed.

[0023] Furthermore, before the calibration process is automatically executed according to the calibration instruction to obtain a plurality of stroke values, the method further includes:

[0024] Detect whether the valve is in a closed state. If the state value indicates that the valve is in a state where liquid cannot flow through, the valve is in a closed state.

[0025] Check whether the valve is in a rigid connection state. If the movable distance of the screw rod is fixed, the valve is in a rigid connection state.

[0026] In the above implementation process, the valve needs to be tested. The calibration process can be carried out only when the valve status is normal to avoid affecting the calibration process.

[0027] Furthermore, it also includes:

[0028] When receiving the unsealing command, the motor is controlled to rotate in the forward direction through the encoder, and the screw of the screw module is driven to rotate in the first direction through the reducer until the screw touches the fixed sleeve of the oil unloading valve and stops;

[0029] When receiving the sealing execution instruction, the motor is controlled to rotate in the reverse direction through the encoder, and the screw of the screw module is driven to rotate in the second direction through the reducer until the screw touches the valve core of the oil unloading valve and stops.

[0030] In the above implementation process, the motor with a reducer and an encoder drives the screw rod to rotate, thereby realizing the unsealing and sealing of the oil unloading valve.

[0034] The calibration success module is used to take the average value of several stroke values ​​as the calibration value and store it on the main board inside the lock if the stroke value meets the set non-discrete algorithm;

[0035] The calibration failure module is used to indicate calibration failure if the stroke value does not meet the set non-discrete algorithm;

[0051] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0052] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] Please see Figure 1 , Figure 1 A flow chart of an automatic calibration method for the lock valve distance of an oil unloading valve provided in an embodiment of the present application. The automatic calibration method for the lock valve distance of an oil unloading valve is applied to an oil unloading valve lock system, the oil unloading valve lock system comprising: a motor module, a screw rod module, an oil unloading valve and a main board inside the lock, the motor module comprising an encoder, a motor and a reducer, the method comprising:

[0054] 100. When installing the switch lock of the oil unloading valve for the first time, receive the calibration instruction.

[0055] It is understood that when installing the switch lock of the oil unloading valve, receiving the calibration instruction ensures that the oil unloading valve can work accurately and safely. Optionally, before installation, ensure that the oil unloading valve and its related equipment are intact.

[0056] It is understandable that the valve needs to be tested, and the calibration process can only be carried out when the valve status is normal to avoid affecting the calibration process. Specifically, check whether the valve is in a closed state. If the status value indicates that the valve is in a state where liquid cannot flow through, the valve is in a closed state; check whether the valve is in a rigid connection state. If the movable distance of the screw rod is fixed, the valve is in a rigid connection state.

[0057] 200. According to the calibration instruction, the calibration process is automatically executed to obtain a plurality of stroke values.

[0058] Specifically, when the main board in the lock receives the calibration instruction, it automatically executes the calibration process according to the calibration instruction, repeatedly executes the sealing action setting group, and each group will obtain two stroke values, and obtain several stroke values; among them, the stroke value represents the movable distance of the screw rod between the current lock and the valve.

[0059] For example, when the lock is first installed, a calibration command needs to be sent after authorization. After receiving the command, the main board in the lock will automatically execute the calibration process, that is, repeatedly perform three groups of sealing / unsealing actions, and each group will get two stroke values, a total of six. The stroke value represents the movable distance of the screw rod between the current lock and the valve. When the six values ​​meet the non-discrete algorithm, the average of the six values ​​is taken as the calibration value and stored on the main board in the lock (not lost when power is off). When the six values ​​do not meet the non-discrete algorithm, the calibration fails.

[0060] 300. If the stroke value satisfies the set non-discrete algorithm, the average value of several stroke values ​​is taken as the calibration value and stored on the main board inside the lock.

[0061] Optionally, it is determined whether the stroke value satisfies a set non-discrete algorithm. Specifically, if the mathematical mean difference of the stroke value is less than a second set threshold, it is determined that the stroke value satisfies the set non-discrete algorithm. Thus, it is determined whether the calibration process is met by determining whether the stroke value satisfies the non-discrete algorithm, so as to detect whether the valve core is closed tightly. Exemplarily, if the mean difference is less than the second set threshold, it is determined that the stroke value satisfies the set non-discrete algorithm.

[0062] 400. If the stroke value does not satisfy the set non-discrete algorithm, it will prompt that the calibration failed.

[0063] Optionally, when judging whether the stroke value satisfies the set non-discrete algorithm, specifically, the median value of the stroke value sequence is taken, and the mathematical mean difference of the stroke values ​​is calculated. If the mathematical mean difference of the stroke values ​​is greater than or equal to a second set threshold, it is judged that the stroke value does not satisfy the set non-discrete algorithm.

[0064] Exemplarily, the median value of the stroke value sequence is taken. Specifically, the stroke values ​​are first sorted, and the 4th of the 6 stroke values ​​is taken from small to large, and then the mathematical mean difference is calculated, that is, each stroke value is subtracted from the median value, the signs are removed and then the sum is calculated. If the mean difference is greater than or equal to the second set threshold, it is determined that the stroke value does not satisfy the set non-discrete algorithm; it can be understood that the specific value of the second set threshold can be set according to specific needs, and the embodiment of the present application is not limited to this.

[0065] 500. When the calibration is completed, the calibration value is stored.

[0066] 600. When receiving an unsealing / sealing instruction, obtain a current stroke value, and compare the current stroke value with a calibration value.

[0067] 700. If the difference between the current stroke value and the calibration value is less than the first set threshold, it is determined that the unsealing / sealing instruction is correct and the current unsealing / sealing is normal.

[0068] 800. If the difference between the current stroke value and the calibration value is greater than the first set threshold, an over-long alarm or a too-short alarm is prompted according to the difference.

[0069] For example, once the calibration is completed, the main board in the lock stores the calibration value. Each time the program executes the unsealing and sealing operation, it will compare the current stroke value with the calibration value. If the difference between the two is less than the first set threshold, it is determined that the unsealing and sealing operation is normal. If the difference between the two is greater than the first set threshold, an alarm for too long or too short stroke is prompted (there is a risk that liquid may flow through the valve).

[0070] As mentioned above, in the embodiment of the present application, when the switch lock of the oil unloading valve is installed for the first time, a calibration instruction is received; according to the calibration instruction, a calibration process is automatically executed to obtain several stroke values; if the stroke value satisfies the set non-discrete algorithm, the average value of several stroke values ​​is taken as the calibration value and stored on the main board in the lock; if the stroke value does not satisfy the set non-discrete algorithm, it is prompted that the calibration failed; when the calibration is completed, the calibration value is stored; when the execution unsealing / sealing instruction is received, the current stroke value is obtained, and the current stroke value is compared with the calibration value; if the difference between the current stroke value and the calibration value is less than the first set threshold value, it is determined that the unsealing / sealing instruction is correct and the unsealing / sealing is normal this time; if the difference between the current stroke value and the calibration value is greater than the first set threshold value, an overlong alarm or a too short alarm is prompted according to the difference; the automatic calibration algorithm can be used for different valve lock distances, and the calibration value that passes the calibration is a reliable valve closed mark, which can be used as a standard for whether the subsequent switch lock is in place, thereby eliminating the oil leakage problem caused by false lock.

[0071] On the basis of the above embodiment, the method for automatic calibration of the locking valve distance of the oil unloading valve can also be embodied as follows:

[0072] When an unsealing instruction is received, the motor is controlled to rotate in the forward direction through the encoder, and the screw of the screw module is driven to rotate in the first direction through the reducer until the screw touches the fixed sleeve of the oil unloading valve and stops; when an execution of sealing instruction is received, the motor is controlled to rotate in the reverse direction through the encoder, and the screw of the screw module is driven to rotate in the second direction through the reducer until the screw touches the valve core of the oil unloading valve and stops; thus, the screw is driven to rotate by the motor with the reducer and the encoder to realize the unsealing and sealing of the oil unloading valve.

[0073] Exemplarily, the oil unloading valve lock used in the embodiment of the present application is a structure of a motor with an encoder and a reducer combined with a screw. The horizontal displacement of the screw is set. The encoder counts one step for each rotation of the motor. Due to the action of the reducer, the horizontal displacement of the screw is only 0.045 mm, that is, the screw position detection accuracy of this lock structure is 0.045 mm. The distance that the screw moves from unsealing to sealing each time is stable, and the corresponding encoder steps do not exceed two steps, and the error does not exceed 0.09 mm.

[0074] The above steps are not to be performed in a strict order as described in the numbers, but should be understood as an overall solution.

[0075] In the second aspect, based on the above embodiments, Figure 2 This is a schematic diagram of the structure of an automatic calibration device for the locking valve distance of an oil unloading valve provided in an embodiment of the present application.

[0077] As mentioned above, in the embodiment of the present application, when the switch lock of the oil unloading valve is installed for the first time, a calibration instruction is received; according to the calibration instruction, a calibration process is automatically executed to obtain several stroke values; if the stroke value satisfies the set non-discrete algorithm, the average value of several stroke values ​​is taken as the calibration value and stored on the main board in the lock; if the stroke value does not satisfy the set non-discrete algorithm, it is prompted that the calibration failed; when the calibration is completed, the calibration value is stored; when the execution unsealing / sealing instruction is received, the current stroke value is obtained, and the current stroke value is compared with the calibration value; if the difference between the current stroke value and the calibration value is less than the first set threshold value, it is determined that the unsealing / sealing instruction is correct and the unsealing / sealing is normal this time; if the difference between the current stroke value and the calibration value is greater than the first set threshold value, an overlong alarm or a too short alarm is prompted according to the difference; the automatic calibration algorithm can be used for different valve lock distances, and the calibration value that passes the calibration is a reliable valve closed mark, which can be used as a standard for whether the subsequent switch lock is in place, thereby eliminating the oil leakage problem caused by false lock.
