DETAILED DESCRIPTION
[0013] The embodiments of the present application provide a valve control system and method to solve the problem in the related art that the detection accuracy of the switch state of the valve cannot be ensured.
[0014] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0015] Figure 1 is a schematic block diagram of a valve control system according to an embodiment of the present application, such as Figure 1 As shown, the system includes a valve 10, a valve detection device 20, a monitoring device 30 and a first control device 40. The valve detection device 20 is arranged on the valve 10, the first control device 40 is connected to the valve 10, the valve detection device 20 and the monitoring device 30 respectively, and the monitoring device 30 is connected to the valve detection device 20.
[0016] The valve detection device is used to detect a first parameter of the valve and send the first parameter to the first control device. The monitoring device is used to monitor the valve detection device, obtain monitoring data of the valve detection device, and send the monitoring data to the first control device. The first control device is used to determine the switch state of the valve according to the first parameter and the monitoring data.
[0017] Optionally, the first parameter includes switch state information. The first parameter and monitoring data may be sent to the first control device via wired or wireless means.
[0018] Optionally, the first control device can be used to determine the first switching state of the valve based on the first parameter, and determine the displayed first parameter based on the monitoring data, match the first switching state and the displayed first parameter to obtain a matching result, and when the matching result is inconsistent, control the valve according to a preset control strategy.
[0019] Wherein, when the matching result is inconsistent, it can be determined that there is an abnormal switch condition in the valve. When the first switch state is closed, and the switch state indicated by the displayed first parameter is open, it can be determined that the first switch state and the displayed first parameter do not match each other; or, when the first switch state is open, and the switch state indicated by the displayed first parameter is closed, it can be determined that the first switch state and the displayed first parameter do not match each other.
[0020] In the operating area of the oil and gas field, the valve may be a valve in a wellhead, a diversion manifold skid, a high- and low-pressure manifold skid, or other high-pressure process manifold skids. The types of valves may include flat valves, plug valves, etc. The monitoring device may be a monitoring camera. The first control device may be disposed at a remote end such as an instrument vehicle, a laptop computer, a desktop computer, or a tablet computer, and the embodiments of the present application are not limited thereto.
[0021] Optionally, the display of the first control device can be software edited via the electro-hydraulic control logic to achieve intuitive presentation on the screen. In the operating area of the oil and gas field, the switch status of the valve on each device can be clearly displayed by displaying open and closed differently, for example, red for closed and green for open. This color coding not only makes it easier for staff to quickly identify the switch status of the valve, but also effectively reduces safety hazards caused by human misjudgment. On the one hand, it can provide remote experts or staff with intuitive abnormal judgment basis for the switch status of the valve, so that they can respond quickly when faced with emergencies; on the other hand, through the logical judgment of the software, the switch status of the valve can also be confirmed with the help of the program, thereby ensuring the consistency and accuracy of information transmission.
[0022] Due to the differences in operations of different equipment and different locations, the switch status of valves is also different. Therefore, when designing a valve control system, it is necessary to fully consider the differentiated needs of various equipment characteristics and formulate corresponding control strategies for each situation. Through the above operations, not only can the switch status of the valve be ensured to be consistent with the operation, thereby ensuring the safety of the operation, but also the overall work efficiency can be improved. In addition, this real-time monitoring and feedback mechanism helps to detect potential problems in a timely manner and take preventive measures, fundamentally reducing the accident rate and creating a safer and more reliable working environment for on-site staff. At the same time, through data recording and analysis, it can provide important reference basis for subsequent optimization management decisions and achieve continuous improvement.
[0023] The valve control system of the embodiment of the present application is adopted, by setting the valve detection device on the valve, connecting the first control device to the valve, the valve detection device and the monitoring device respectively, and connecting the monitoring device to the valve detection device. In this way, the valve detection device can detect the first parameter of the valve and send the first parameter to the first control device, and the first parameter includes the switch state information. At the same time, the monitoring device can monitor the valve detection device, obtain the monitoring data of the valve detection device, and send the monitoring data to the first control device. Thus, the first control device can determine the switch state of the valve according to the first parameter and the monitoring data. It can be seen that the technical solution can automatically detect the switch state of the valve, reduce the uncertainty caused by human factors, and thus improve the reliability of the switch state of the determined valve. Moreover, in the process of determining the switch state of the valve, the technical solution is not only based on the first parameter transmitted by the valve detection device, but also combines the first parameter and the monitoring data of the valve detection device, so as to achieve the purpose of verifying the switch state of the valve, and can effectively avoid the problem of inaccurate detection of the switch state of the valve caused by data transmission errors, improve the detection accuracy of the switch state of the valve, and facilitate the realization of more accurate control of the valve.
[0024] In one embodiment, the first parameter may include valve position detection data. The first control device may be used to determine the current position of the valve according to the valve position detection data. When the current time is within the valve opening period and the current position of the valve is not at the preset opening position, the valve is controlled to be opened. When the current time is within the valve closing period and the current position of the valve is not at the preset closing position, the valve is controlled to be closed.
[0025] In this embodiment, valve position detection data is obtained by detecting through the valve detection device, and the valve position detection data is sent to the first control device, which is beneficial for the first control device to judge whether the valve is fully opened or closed, thereby accurately controlling the opening or closing of the valve to ensure that the valve is fully opened or fully closed, thereby ensuring the safety of valve operation.
[0026] In one embodiment, the first parameter may include a first operating temperature and a first operating pressure. The first control device may be used to control the valve to close when the first parameter meets a preset valve closing condition.
[0027] The preset valve closing condition may include: the first operating temperature is greater than or equal to a preset temperature threshold; and / or the first operating pressure is greater than or equal to a preset pressure threshold.
[0028] In this embodiment, the first operating temperature and the first operating pressure of the valve are detected by the valve detection device and sent to the first control device, so that the first control device can promptly know that the operating temperature and / or operating pressure exceed the corresponding preset threshold value based on the preset temperature threshold value and the preset pressure threshold value, thereby controlling the valve to close in time, which is beneficial to ensure the safety of the valve operation.
[0029] In one embodiment, the first control device can be used to perform the following steps A1 to A3: Step A1, obtaining a second parameter of the valve in multiple operations. The second parameter may include at least one of the following: total operation time, a first number of times that the first operation temperature reaches a preset temperature threshold, and a second number of times that the first operation pressure reaches a preset pressure threshold.
[0030] The first parameter may include a first operation duration, and the total operation duration may be determined based on the first operation duration of the valve in multiple operations. The first number may be determined based on the first operation temperature of the valve in multiple operations. The second number may be determined based on the first operation pressure of the valve in multiple operations.
[0031] Step A2, determining whether the valve meets the preset maintenance condition according to the second parameter. The preset maintenance condition may include at least one of the following: the total operation time reaches the preset time; the first number is greater than or equal to the first preset number; the second number is greater than or equal to the second preset number.
[0032] Step A3: When it is determined that the valve meets the preset maintenance conditions, a prompt message is issued. The prompt message is used to prompt the valve to be maintained.
[0033] In this embodiment, the second parameter is obtained by recording and analyzing the first parameter received in multiple operations in the first control device, which provides a data basis for determining the maintenance timing of the valve, is conducive to timely maintenance of the valve, and reduces the accident rate of valve operations.
[0034] In one embodiment, Figure 2 As shown, the valve detection device may include a state detection unit 210 and a first display unit 220 connected to each other. The state detection unit 210 is connected to the first control device 40. The first display unit 220 is connected to the monitoring device 30. It should be noted that, Figure 2 is Figure 1 The schematic block diagram of the valve detection device is refined on the basis of Figure 2 Zhongyu Figure 1 For the connection relationship between components with the same label, please refer to Figure 1 , I will not go into details here.
[0035] The state detection unit is used to detect the first parameter and send the first parameter to the first display unit and the first control device respectively. The first display unit is used to receive and display the first parameter.
[0036] Optionally, the state detection unit may include an operation duration monitoring module, an operation pressure detection module, an operation temperature detection module, a valve position detection module, etc. The valve position detection module may use a sensor to detect the current position of the valve, and if the detected current position is not located at a preset open position or a preset closed position, the valve position detection data is output; if the detected current position is located at a preset open position or a preset closed position, the switch state information is output. The first parameter may include switch state information, valve position detection data, a first operation duration, a first operation pressure, a first operation temperature, etc. The first display unit may display the first parameter by digital display and / or indicator light display.
[0037] During the operation of oil and gas fields, the function of the valve is to realize the on-off regulation of fluid flow, and there are only two switch states: open and closed. In this embodiment, for the flat valve, a valve position detection module can be installed at the tail rod of the valve to detect the switch state of the linear displacement valve; for the plug valve, its rotation can be detected to detect the switch state of the angular stroke valve.
[0038] Among them, the core component of the flat valve lies in the matching degree of the position of the through hole between the valve plate and the valve seat. The valve seat is a fixed component, and the valve plate is a displaceable component. With the displacement of the valve plate position, when the through hole positions of the valve plate and the valve seat are mutually adapted, the valve is in an open state; conversely, when the positions of the two do not match, the valve is in a closed state. The displacement of the valve plate will also drive the displacement of the tail rod, which is isolated from the atmosphere by the rod sealing assembly, so the switch state of the valve can be determined based on the extension of the tail rod.
[0039] The movement of the flat valve shows a linear displacement trend. Switches can be used to detect the floating stroke of the valve tail rod by using the detection path of the starting position and the end position, such as inductive proximity switches, reed switches, limit switches, etc.; displacement sensors (or distance sensors) can also be used to detect the displacement of the tail rod, such as laser rangefinders, pull rope sensors, etc.
[0040] Optionally, the sensor can be firmly mounted on the tail stem shield of the valve using a bracket structure to achieve point detection and monitoring. The installation forms include arc brackets, steel pipe brackets, and throat clamp brackets.
[0041] Since the plug valve is a 90° rotating valve, its rotation angle information can be transmitted back through external rotation operation. The valve position is mainly displayed by the positions of the open and closed positions after 90° rotation to indicate the valve position. The signal can be confirmed at the start and end positions by means of limit switches. The position can also be confirmed by using the performance of angle sensors.
[0042] In this embodiment, the status detection unit detects the first parameter and sends the first parameter to the first display unit and the first control device respectively, and the first display unit can receive and display the first parameter, which not only provides a data basis for the first control device to determine the switching status of the valve, but also enables the staff to clearly understand the switching status of the valve based on the first display unit, thereby facilitating timely detection of abnormal switching conditions of the valve.
[0043] In one embodiment, there are multiple valves, and each valve is provided with a state detection unit and a first display unit connected to each other. The valve control system may include multiple data acquisition devices 50, each of which is connected between the first control device 40 and the state detection unit 210, and each of which is connected to multiple state detection units 210. For example, Figure 3 A data acquisition device 50 in a valve control system and its connection relationship are shown. It should be noted that: Figure 3 is Figure 2 Based on the refinement of the valve control system, the schematic block diagram is obtained. Therefore, Figure 3 Zhongyu Figure 2 For the connection relationship between components with the same label, please refer to Figure 2 , I will not go into details here.
[0044] The data acquisition device is used to acquire the first parameter detected by the state detection unit, construct a mapping relationship between the valve identifier of the valve and the first parameter, and send the mapping relationship to the first control device.
[0045] The monitoring device can be used to monitor the first display unit, obtain monitoring data of the first display unit, and send the monitoring data to the first control device. The first control device can be used to determine the switch state of the valve according to the mapping relationship and the monitoring data.
[0046] Optionally, in order to ensure the reliability of information transmission, the data acquisition device can adopt multiple communication protocols, such as Modbus communication protocol, CAN (Controller Area Network) protocol, etc., to realize data interaction with different devices.
[0047] In this embodiment, multiple data acquisition devices are set in the valve control system, and one data acquisition device is used to collect the first parameters detected by multiple state detection units, so that the first parameters detected by the state detection units are summarized to obtain a mapping relationship and then sent, which is beneficial to improving data transmission efficiency.
[0048] In the operating area of the oil and gas field, the switch status detection of the valve includes the flat valves of different wellheads. For example, the platform well often has multiple wellheads. In this embodiment, a state detection unit can be installed on each valve position. These state detection units can detect the key parameters such as the switch status, pressure and temperature of the valve in real time, thereby providing a basis for subsequent data analysis. In addition, it also involves multiple skid-mounted or independent plug valves at the well site. A state detection unit can be configured on each plug valve to ensure efficient operation even in complex operating environments.
[0049] By adopting the technical solution of this embodiment, in the operating area of the oil and gas field, the data acquisition device can be installed near the skid group or the product assembly. For example, a wellhead can be set as a unit. A wellhead usually includes multiple valves. A data acquisition device can be set at the wellhead to collect the first parameter detected by the state detection unit of the multiple valves included in the wellhead, and the first parameter is associated with the valve identification of the valve to map and integrate to obtain a mapping relationship table of the wellhead, and the mapping relationship table includes a mapping relationship between the first parameter and the valve identification. Similarly, the diversion manifold skid, high and low pressure manifold skid, etc. can be set with reference to the wellhead. Figure 4Schematically showing the data acquisition device 50 installed at the wellhead 41 and the diversion manifold skid 42, Figure 5 Schematically shows a data acquisition device 50 disposed at the high and low pressure manifold skid 43 .
[0050] This networking structure can not only improve the data transmission efficiency between devices, but also effectively reduce signal attenuation and interference, thereby ensuring the accuracy and real-time nature of information. At the same time, such an arrangement is convenient for fixing addresses and can achieve accurate identification and positioning, which provides convenience for subsequent data analysis and troubleshooting, and takes into account the convenience of maintenance and repair, so that staff can quickly locate relevant equipment during daily inspections, thereby improving work efficiency. In addition, by rationally planning the location of each component, the workflow of the overall system can be optimized, so that a good synergy can be formed between the components.
[0051] In one embodiment, the monitoring data may include a valve identification of the valve and a first parameter displayed by the first display unit. The first control device may be used to perform the following steps B1 to B3: Step B1, determining a first switch state corresponding to the valve identifier according to a mapping relationship; and determining a first parameter corresponding to the valve identifier according to monitoring data.
[0052] The mapping relationship includes a mapping relationship between a valve identifier of the valve and a first parameter. The first control device can determine a first switch state of the valve according to the first parameter, thereby determining a first switch state corresponding to the valve identifier according to the mapping relationship.
[0053] Optionally, the monitoring data may be a monitoring screen of the first display unit, and the first control device may determine the first parameter corresponding to the valve identifier by identifying the first parameter and the valve identifier displayed on the monitoring screen.
[0054] Step B2: matching the first switch state and the first parameter according to the valve identifier to obtain a matching result.
[0055] The first switch state and the first parameter with the same valve identifier may be matched.
[0056] Step B3: When the matching result is inconsistent, the valve is controlled according to a preset control strategy.
[0057] Optionally, the preset control strategy can be a control strategy formulated for each situation by taking into full consideration the differentiated requirements of various equipment characteristics when designing the valve control system, and the embodiment of the present application does not limit this. For example, if the matching result is inconsistent, an alarm message can be issued, and the alarm message is used to indicate that the switch state of the valve is abnormal.
[0058] In one embodiment, Figure 6 As shown, the valve control system may include a second control device 60, which is connected to the state detection unit, the first control device and the valve respectively. In the case where the valve control system includes a data acquisition device, the second control device 60 is connected between the data acquisition device 50 and the first control device 40, and is connected between the valve 10 and the first control device 40. It should be noted that Figure 6 is Figure 3 Based on the refinement of the valve control system, the schematic block diagram is obtained. Therefore, Figure 6 Zhongyu Figure 3 For the connection relationship between components with the same label, please refer to Figure 3 , I will not go into details here.
[0059] The first control device can be used to send a switch control signal to the second control device when the valve meets a preset driving condition.
[0060] The preset driving condition includes at least one of the following: the valve opening time or the valve closing time is reached, the current time is within the valve opening period and the current position of the valve is not at the preset opening position, the current time is within the valve closing period and the current position of the valve is not at the preset closing position, and the first parameter meets the preset valve closing condition. Optionally, the first control device can be set locally in the oil and gas field.
[0061] The second control device can be used to obtain the first parameter, and when the first parameter matches the switch control signal, control the valve to open or close according to the switch control signal.
[0062] Among them, when the switch state indicated by the first parameter is open and the switch control signal is used to control the valve to close, it can be determined that the first parameter matches the switch control signal; or, when the switch state indicated by the first parameter is closed and the switch control signal is used to control the valve to open, it can be determined that the first parameter matches the switch control signal.
[0063] In this embodiment, the second control device compares and analyzes the received switch control signal and the first parameter, so that the switch state of the valve can be determined again before controlling the valve to open or close, which is conducive to timely detection of abnormal switching conditions of the valve, thereby facilitating more precise control of the valve and effectively reducing the accident rate of valve operation.
[0064] In one embodiment, Figure 7As shown, the second control device includes a control unit 610, a second display unit 620 and a drive unit 630, and the control unit 610 is connected to the second display unit 620 and the drive unit 630 respectively. The control unit is connected between the state detection unit and the first control device, and the drive unit 630 is connected to the valve 10. In the case where the valve control system includes a data acquisition device, the control unit 610 is connected between the data acquisition device 50 and the first control device 40. It should be noted that Figure 7 is Figure 6 The schematic block diagram of the second control device is obtained by refining the second control device based on the above, therefore, Figure 7 Zhongyu Figure 6 For the connection relationship between components with the same label, please refer to Figure 6 , I will not go into details here.
[0065] The state detection unit can be used to send the first parameter to the second display unit. The second display unit is used to receive and display the first parameter. The first control device can be used to send a switch control signal to the control unit when the valve meets the preset driving condition.
[0066] The control unit can be used to obtain the first parameter displayed by the second display unit, and when the first parameter matches the switch control signal, generate a drive signal according to the switch control signal, and send the drive signal to the drive unit. The drive unit can be used to drive the valve to open or close according to the drive signal.
[0067] Optionally, the control unit may adopt a PLC (Programmable Logic Controller), and the drive unit may include a hydraulic drive motor, a grease injection motor, an electric actuator, a pneumatic actuator, etc. The second display unit may display the first parameter by digital display and / or indicator light display. The display mode of the second display unit may be the same as or different from the display mode of the first display unit.
[0068] In this embodiment, on the one hand, the second display unit can display the first parameter of the valve in real time, which is helpful for the staff to clearly know the switch status of the valve at the second control device without the need for the staff to go deep into the operation area; on the other hand, the control unit can receive the switch control signal sent by the first control device, generate a drive signal, and use the drive unit to drive the valve to open or close, so that the instructions of the first control device are effectively converted into actual control actions, and the control actions are directly directed to the valve through the mechanical structure to control the valve to open or close accurately. In this way, the valve control is realized automatically, which not only improves the operating efficiency of the valve control system, but also enhances the overall operation safety.
[0069] The above is a valve control system provided in the embodiment of the present application. Based on the same idea, the embodiment of the present application also provides a valve control method.
[0070] Figure 8 is a schematic flow chart of a valve control method according to an embodiment of the present application. In this embodiment, the valve control method is applied to Figures 1 to 7 The valve control system shown in Figure 1 is shown in Figure 2. Figure 8 As shown, the method includes: S802, detecting a first parameter of the valve, where the first parameter includes switch state information.
[0071] In one embodiment, the first parameter may be displayed in a digital manner and / or by an indicator light.
[0072] S804, monitoring the valve detection device to obtain monitoring data of the valve detection device.
[0073] Optionally, the monitoring data may be a monitoring screen of the valve detection device.
[0074] S806: Determine the switch state of the valve according to the first parameter and the monitoring data.
[0075] Optionally, determining the switching state of the valve according to the first parameter and the monitoring data can be executed as follows: determining the first switching state of the valve according to the first parameter, and determining the displayed first parameter according to the monitoring data, matching the first switching state and the displayed first parameter to obtain a matching result, and when the matching result is inconsistent, controlling the valve according to a preset control strategy.
[0076] Wherein, when the matching result is inconsistent, it can be determined that there is an abnormal switch condition in the valve. When the first switch state is closed, and the switch state indicated by the displayed first parameter is open, it can be determined that the first switch state and the displayed first parameter do not match each other; or, when the first switch state is open, and the switch state indicated by the displayed first parameter is closed, it can be determined that the first switch state and the displayed first parameter do not match each other.
[0077] The technical solution of the embodiment of the present application is adopted, by detecting the first parameter of the valve, the first parameter includes the switch state information. At the same time, the valve detection device is monitored to obtain the monitoring data of the valve detection device. Thus, the switch state of the valve is determined according to the first parameter and the monitoring data. It can be seen that the technical solution can automatically detect the switch state of the valve, reduce the uncertainty caused by human factors, and thus improve the reliability of the determined switch state of the valve. Moreover, in the process of determining the switch state of the valve, the technical solution is not only based on the detected first parameter of the valve, but also combines the first parameter and the monitoring data of the valve detection device, thereby achieving the purpose of verifying the switch state of the valve, and can effectively avoid the problem of inaccurate detection of the switch state of the valve caused by data transmission errors, improve the detection accuracy of the switch state of the valve, and facilitate more precise control of the valve.
[0078] In one embodiment, the first parameter may include valve position detection data. After detecting the first parameter of the valve (i.e., S802), the following may be performed: determining the current position of the valve according to the valve position detection data. When the current time is within the valve opening period and the current position of the valve is not at the preset opening position, controlling the valve to open. When the current time is within the valve closing period and the current position of the valve is not at the preset closing position, controlling the valve to close.
[0079] In this embodiment, it is possible to determine whether the valve is fully opened or fully closed, thereby accurately controlling the opening or closing of the valve to ensure that the valve is fully opened or fully closed, thereby ensuring the safety of the valve operation.
[0080] In one embodiment, the first parameter may include a first operating temperature and a first operating pressure. After detecting the first parameter of the valve (ie S802 ), the following may be performed: when the first parameter meets a preset valve closing condition, the valve is controlled to close.
[0081] The preset valve closing conditions include: the first operating temperature is greater than or equal to a preset temperature threshold; and / or the first operating pressure is greater than or equal to a preset pressure threshold.
[0082] In this embodiment, based on the preset temperature threshold and the preset pressure threshold, it is possible to promptly know that the operating temperature and / or operating pressure exceeds the corresponding preset threshold, so as to timely control the valve closure, which is conducive to ensuring the safety of valve operation.
[0083] In one embodiment, the valve control method may include the following steps C1 to C3: Step C1, obtaining a second parameter of the valve in multiple operations. The second parameter includes at least one of the following: total operation time, a first number of times that the first operation temperature reaches a preset temperature threshold, and a second number of times that the first operation pressure reaches a preset pressure threshold.
[0084] Step C2: determining whether the valve meets a preset maintenance condition based on the second parameter.
[0085] Among them, the preset maintenance conditions include at least one of the following: the total operation duration reaches the preset duration; the first number is greater than or equal to the first preset number; the second number is greater than or equal to the second preset number.
[0086] Step C3: When it is determined that the valve meets the preset maintenance conditions, a prompt message is issued. The prompt message is used to prompt the valve to be maintained.
[0087] In this embodiment, the second parameter is obtained by recording and analyzing the first parameter received in multiple operations, which provides a data basis for determining the maintenance timing of the valve, is conducive to timely maintenance of the valve, and reduces the accident rate of valve operations.
[0088] In one embodiment, the above S802-S806 may be executed as the following steps D1-D3: Step D1, collecting a first parameter detected by a state detection unit, and constructing a mapping relationship between a valve identifier of a valve and the first parameter.
[0089] Step D2, monitoring the first display unit to obtain monitoring data of the first display unit.
[0090] Step D3, determining the switch state of the valve according to the mapping relationship and the monitoring data.
[0091] Optionally, the monitoring data includes a valve identification of the valve and a first parameter displayed by the first display unit. Step D3 can be performed as follows: Step D31-Step D33: Step D31, determining a first switch state corresponding to the valve identifier according to the mapping relationship; and determining a first parameter corresponding to the valve identifier according to the monitoring data.
[0092] Step D32, matching the first switch state and the first parameter according to the valve identifier to obtain a matching result.
[0093] Step D33: When the matching result is inconsistent, the valve is controlled according to a preset control strategy.
[0094] In this embodiment, the first parameters detected by multiple state detection units are collected by a data collection device in the valve control system, so that the first parameters detected by the state detection units are summarized to obtain a mapping relationship and then sent, which is conducive to improving data transmission efficiency.
[0095] In one embodiment, when the valve meets a preset driving condition and the first parameter matches the switch control signal, the valve can be controlled to be opened or closed according to the switch control signal.
[0096] Among them, the preset driving conditions include at least one of the following: the valve opening time or the valve closing time arrives, the current time is within the valve opening period and the current position of the valve is not at the preset opening position, the current time is within the valve closing period and the current position of the valve is not at the preset closing position, and the first parameter meets the preset valve closing condition.
[0097] In this embodiment, by comparing and analyzing the switch control signal and the first parameter, the switch state of the valve can be determined again before controlling the valve to open or close, which is conducive to timely detection of abnormal switching conditions of the valve, thereby facilitating more precise control of the valve and effectively reducing the accident rate of valve operation.
