It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] In one embodiment, Figure 1 Schematic diagram of the structure of an oil separator switching system provided in an embodiment of the present invention. This embodiment can be applied to the case where the service life of the first oil separator and the second oil separator installed on the ship is increased, such as Figure 1As shown, the structure includes a switch module 1, a control module 2, a diesel engine 3, a first oil separator 4 and a second oil separator 5; the first oil separator 4 is connected to the first port of the switch module 1; the second oil separator 5 is connected to the second port of the switch module 1, and the diesel engine 3 is connected to the third port of the switch module 1; the control module 2 is electrically connected to the switch module 1; the first oil separator 4 is used to input oil to the first port; the second oil separator 5 is used to input oil to the second port; the switch module 1 includes a first conduction state and a second conduction state, the first conduction state is that the first port and the third port are both conductive, and the second conduction state is that the second port and the third port are both conductive; the control module 2 is used to control the switch module 1 to switch between the first conduction state and the second conduction state according to a preset switching condition, so that when the switch module 1 is in the first conduction state, the oil is input from the first port and the third port to the diesel engine 3; when the switch module 1 is in the second conduction state, the oil is input from the second port and the third port to the diesel engine 3.

[0040] The switch module 1 includes a first port, a second port and a third port, wherein the pipeline connected to the first port and the third port is a first flow pipeline, and the pipeline connected to the second port and the third port is a second flow pipeline. The switch module 1 is used to control the flow of oil in one of the flow pipelines. In this embodiment, the switch module 1 may include but is not limited to a three-way valve. The first oil separator 4 and the second oil separator 5 are centrifugal sedimentation equipment, which are mainly used on ships. Their core function is to separate water, impurities and particles in fuel and lubricating oil to ensure the purity of the oil. The working principle of the first oil separator 4 and the second oil separator 5 is centrifugal separation technology. The centrifugal force generated by high-speed rotation makes the oil, water and impurities distributed in layers according to different densities, thereby achieving separation. The oil separated in the first oil separator 4 will be input to the first port of the switch module 1, and the oil separated in the second oil separator 5 will be input to the second port of the switch module 1. The control module 2 is the core control module of this embodiment, which is used to control the switch module 1 to switch between the first conduction state and the second conduction state according to the preset switching conditions. The first conducting state is that the first port and the third port of the switch module 1 are conducting, and the second conducting state is that the second port and the third port of the switch module 1 are conducting. When the switch module 1 is in the first conducting state, only the oil in the first oil separator 4 can flow to the diesel engine 3; when the switch module 1 is in the second conducting state, only the oil in the second oil separator 5 can flow to the diesel engine 3.

[0041] Specifically, when switching between the first oil separator 4 and the second oil separator 5, one of the oil separators can be controlled to work first according to the demand. Taking the operation of the first oil separator 4 as an example, the oil in the first oil separator 4 is circulated to the diesel engine 3. In this embodiment, the first oil separator 4 is connected to the first port of the switch module 1, and the diesel engine 3 is connected to the third port of the switch module 1. Therefore, if the oil in the first oil separator 4 needs to be circulated to the diesel engine 3, the control module 1 needs to control the first port and the third port of the switch module 1 to be connected, that is, the switch module 1 is controlled to be in the first conducting state, and the second port is in the disconnected state at this time. After the oil separated by the first oil separator 4 is input to the first port and the third port, it will flow to the diesel engine 3 through the first port and the third port to ensure the normal operation of the diesel engine 3. When the preset switching conditions are met, wherein the preset switching conditions may be that the working time of the first oil separator 4 reaches the preset time, or when the current state parameters of the oil in the diesel engine 3 are abnormal, indicating that the first oil separator 4 can no longer continue to work to provide oil to the diesel engine 3, and the oil separator switching is required, the control module 2 will control the switch module 1 to switch from the first conduction state to the second conduction state, that is, control the second port and the third port to be conductive, and the first port to be disconnected. Since the second oil separator 5 is connected to the second port of the switch module 1, when the second port and the third port are conductive and the first port is disconnected, the oil in the first oil separator 4 will not flow to the third port after being input to the first port. After the separated oil in the second oil separator 5 is input to the second port, it will flow to the diesel engine 3 through the second port and the third port, thereby realizing the rapid switching between the first oil separator 4 and the second oil separator 5. Similarly, when the operation of the second oil separator 5 meets the preset switching conditions, the control module 2 will control the switch module 1 to switch from the second conduction state to the first conduction state, even if the first port and the third port of the switch module 1 are turned on, the oil separated by the second oil separator 5 will not flow to the diesel engine 3, and the oil separated by the first oil separator 4 will flow to the diesel engine through the first port and the third port, thereby realizing the switching between the second oil separator 5 and the first oil separator 4.

[0042] The technical solution of the embodiment of the present invention is to set a switch module, which includes a first conduction state and a second conduction state. When the switch module is in the first conduction state, the oil separated by the first oil separator flows to the diesel engine through the first port and the third port; when the switch module is in the second conduction state, the oil separated by the second oil separator flows to the diesel engine through the second port and the third port; when the first oil separator or the second oil separator is working, the control module controls the switch module to switch between the first conduction state and the second conduction state according to the preset switching conditions, so that the oil separated by the first oil separator or the second oil separator flows to the diesel engine. With the above structure, fast switching between the first oil separator and the second oil separator is realized, the loss of the first oil separator or the second oil separator is reduced, and the service life of the oil separator is extended.

[0043] Optional, Figure 2 The structural diagram of the second oil separator switching system provided by the embodiment of the present invention is shown in FIG. Figure 2 As shown, the system also includes an oil detection module 6; the oil detection module 6 is electrically connected to the diesel engine 3 and the control module 2 respectively; the oil detection module 6 is used to detect the current state parameters of the oil entering the diesel engine 3; the control module 2 is also used to receive the current state parameters of the oil, and determine the state of the oil in combination with the preset state parameter conditions; when the oil is in an abnormal state, the control switch module 1 switches between the first conduction state and the second conduction state.

[0044] The oil detection module 6 is used to detect the current state parameters of the oil input to the diesel engine 3 , and send the current state parameters of the oil to the control module 2 .

[0045] Specifically, after the oil in the first oil separator 4 or the second oil separator 5 flows to the diesel engine 3, the oil detection module 6 connected to the diesel engine 3 will detect the current state parameters of the oil in real time, and send the detected current state parameters to the control module 2. After receiving the current state parameters of the oil, the control module 2, based on the current state parameters and in combination with the parameter threshold corresponding to the current state parameters, when the current state parameters of the oil are outside the corresponding threshold, it indicates that the current state parameters of the oil are too high or too low, and then it is determined that the oil is in an abnormal state, and the oil separated in the current oil separator can no longer meet the normal use requirements, then the control module 2 will control the switch module 1 to switch from the first conduction state to the second conduction state, so as to switch from the first oil separator 4 to the second oil separator 5; or, the control module 2 will control the switch module 1 to switch from the second conduction state to the first conduction state, so as to switch from the second oil separator 5 to the first oil separator 4.

[0046] In another specific embodiment, optionally, the current state parameters of the oil include at least the particle content, particle concentration and pressure of the oil; the control module 2 is also used to determine that the oil is in an abnormal state when it is determined that the particle content of the oil is higher than a preset particle content threshold, and / or the particle concentration is higher than a preset particle concentration threshold, and / or the pressure of the oil is lower than a preset pressure threshold.

[0047] Specifically, after the control module 2 receives the current state parameters of the oil, the current state parameters of the oil may include the particle content, particle concentration and pressure of the oil. When it is determined that the particle content of the oil is higher than the preset particle content threshold, and / or the particle concentration is higher than the preset particle concentration threshold, and / or the pressure of the oil is lower than the preset pressure threshold, it indicates that there are too many particles in the oil and it is dirty. Then it is determined that the oil is in an abnormal state, and the switch module 1 is controlled to switch between the first conduction state and the second conduction state. In addition, the current state parameters of the oil also include the oil content. When it is determined that the oil content is lower than the preset content threshold, it indicates that there is too little oil flowing into the diesel engine 3, that is, the oil is not in place, and then it is determined that the oil is in an abnormal state.

[0048] It should be noted that when determining whether the oil is dirty, the dirtiness of the oil can be determined based on at least one of the particle content, particle concentration, and pressure of the oil. Normally, when the detection requirements are low, the oil can be determined to be dirty directly based on the relationship between the oil pressure and the preset pressure threshold. When the oil pressure is lower than the preset pressure threshold, the oil can be determined to be dirty. However, in actual operation, in order to improve the accuracy of detection and avoid misjudgment, in addition to detecting the oil pressure, the particle content and particle concentration of the oil will also be detected. When the oil pressure is lower than the preset pressure threshold, the oil particle content is higher than the preset particle content threshold, and the particle concentration is higher than the preset particle concentration threshold, it can be more accurately determined that the oil is dirty and is in an abnormal state.

[0049] Optional, continue to refer to Figure 2 The system also includes a manual valve 7; the manual valve 7 is electrically connected to the oil detection module 6, and the manual valve 7 is connected between the oil detection module 6 and the diesel engine 3; the oil detection module 6 is also used to confirm that a manual valve conduction instruction generated when the user turns the manual valve 7 is received before detecting the current state parameters of the oil entering the diesel engine 3.

[0050] Among them, the manual valve 7 is a valve that requires manual operation to control the flow of fluid (such as liquid, gas, etc.). It is usually used in a pipeline system to open or close the flow of fluid, or to adjust the flow and pressure of the fluid. In this embodiment, the manual valve 7 is connected between the diesel engine 3 and the oil detection module 6. Before the oil detection module 6 detects the current state parameters of the oil in the diesel engine 3, the manual valve 7 needs to be rotated to the conduction position so that the oil detection module 6 detects the oil in the diesel engine 3. In other words, before the oil detection module 6 detects the current state parameters of the oil in the diesel engine 3, it is necessary to confirm that the manual valve conduction instruction generated when the user turns the manual valve 7 to the conduction position is received. After receiving the manual valve conduction instruction, it indicates that the user has turned the manual valve 7 to the conduction position, and the current state parameters of the oil in the diesel engine 3 are detected.

[0051] Optional, continue to refer to Figure 2 The system also includes a display module 8; the display module 8 is electrically connected to the control module 2; the control module 2 is used to control the display module 8 to display the current state parameters after receiving the current state parameters.

[0052] Among them, the display module 8 is used to display the current state parameters of the oil. The display module 8 may include but is not limited to devices that can be used for display, such as a display screen, a liquid crystal screen or a projector. In the present embodiment, the display module 8 includes a local display unit and a remote display unit. The local display unit is used to display the current state parameters of the oil near the control module 8, and the remote display unit displays the current state parameters of the oil in a remote location, such as an office or a laboratory. To ensure adaptability, the remote display unit can be connected to the control module 2 through an adapter, such as a server, when it is electrically connected. After receiving the current state parameters of the oil, the control module 2 will display the received current state parameters on the display module 8 so that the user can view the current parameter results.

[0053] In addition, the current state parameters of the oil also include the oil pressure and the oil temperature. The display module 8 can also display the oil pressure and the oil temperature detected by the oil detection module 6 for the user to view.

[0054] Optional, continue to refer to Figure 2 The system also includes a valve feedback 9 and an open limit plate (not shown in the figure), and the valve feedback 9 is electrically connected to the open limit plate and the control module 2 respectively; the valve feedback 9 is used to generate a first successful conduction signal when the first port and the third port reach the limit of the open limit plate; the control module 2 is also used to confirm the receipt of the first successful conduction signal when the control switch module 1 is in the first conduction state; the valve feedback 9 is also used to generate a second successful conduction signal when the second port and the third port reach the limit of the open limit plate; the control module 2 is also used to confirm the receipt of the second successful conduction signal when the control switch module 1 is in the second conduction state.

[0055] Among them, the valve feedback 9 refers to the monitoring of the actual position state of the valve or switch by a specific sensor or feedback device in the industrial automation control system. In this embodiment, an open limit plate is also provided, and the open limit plate is located at the limit position of the first port, the second port and the third port of the switch module 1. The open limit plate is electrically connected to the valve feedback 9. When the control module 2 controls the switch module 1 to be in the first conduction state, that is, the first port and the third port are connected, and at this time, the first port and the third port are both connected to the limit of the open limit plate, the valve feedback 9 will generate a first conduction success signal and send it to the control module 2. That is, when the control module 2 controls the switch module 1 to be in the first conduction state, it will confirm that the first conduction success signal sent by the valve feedback 9 is received, indicating that the first port and the third port are in place. When the control module 2 controls the switch module 1 to be in the second conduction state, that is, the second port and the third port are connected, and at this time, the second port and the third port are both connected to the limit of the open limit plate, the valve feedback 9 will generate a second conduction success signal and send it to the control module 2. That is, when the control module 2 controls the switch module 1 to be in the second conduction state, it will confirm that the second conduction success signal sent by the valve feedback 9 is received, indicating that the second port and the third port are fully conductive.

[0056] It should be noted that the system can also be provided with a closing limit plate, which is electrically connected to the valve feedback 9. When the control module 2 controls the switch module 1 to be in the first conduction state, the valve feedback 9 will not only generate a first conduction success signal when the first port and the third port are both conducted to the limit of the open limit plate, but also generate a first shutdown success signal when the second port is closed to the closing limit plate. When the control module 2 controls the switch module 1 to be in the first conduction state, it will confirm the reception of the first conduction success signal and the first shutdown success signal. Similarly, when the control module 2 controls the switch module 1 to be in the second conduction state, the valve feedback 9 will not only generate a second conduction success signal when the second port and the third port are both conducted to the limit of the open limit plate, but also generate a second shutdown success signal when the first port is closed to the closing limit plate. When the control module 2 controls the switch module 1 to be in the second conduction state, it will confirm the reception of the second conduction success signal and the second shutdown success signal to determine whether the port is in place for conduction or shutdown.

[0057] Optional, Figure 3 The structural diagram of the third oil separator switching system provided by the embodiment of the present invention is shown in FIG. Figure 3As shown, the system also includes a timing module 10; the timing module 10 is electrically connected to the control module 2; the control module 2 is also used to control the timing module 10 to start timing when the control switch module 1 is in the first conduction state, and control the switch module 1 to switch to the second conduction state when the timing duration reaches the preset working duration; when the control switch module 1 is in the second conduction state, the timing module 10 starts timing, and controls the switch module 1 to switch to the first conduction state when the timing duration reaches the preset working duration.

[0058] The timing module 10 is used for timing when the first conducting state or the second conducting state starts.

[0059] Specifically, when the control module 2 controls the switch module 1 to be in the first conduction state, it will control the timing module 10 to start timing, and at this time the first oil separator 4 starts to work. When the timing duration reaches the preset working duration, it indicates that the working duration of the first oil separator 4 has reached the preset working duration and cannot continue to work, and it is necessary to switch the oil separator to ensure the service life of the first oil separator 4. Therefore, the control module 2 will control the switch module 1 to switch to the second conduction state to enable the second oil separator 5 to work. Similarly, when the control module 2 controls the switch module 1 to be in the second conduction state, it will control the timing module 10 to start timing, and at this time the second oil separator 5 starts to work. When the timing duration reaches the preset working duration, it indicates that the working duration of the second oil separator 5 has reached the preset working duration and cannot continue to work, and it is necessary to switch the oil separator to ensure the service life of the second oil separator 5. Therefore, the control module 2 will control the switch module 1 to switch to the first conduction state to enable the first oil separator 4 to work.

[0060] It should be noted that when the control module 2 controls the switch module 1 to be in the first conduction state and controls the timing module 10 to start timing, the oil detection module 6 will also detect the current state parameters of the oil in the diesel engine 3 in real time and send them to the control module 2. When the control module 2 determines that the oil is abnormal within the preset working time, it does not need to wait for the first oil distributor 4 to work for the preset working time, but directly controls the switch module 1 to switch from the first conduction state to the second conduction state. When the control module 2 determines that the oil is normal within the preset working time, the control module 2 will control the switch module 1 to switch to the second conduction state after the working time of the first oil distributor 4 reaches the preset working time, so that the second oil distributor 5 can work. Exemplarily, the preset working time is 24h. Similarly, the logic of the control module 2 controlling the switch module 1 to switch from the second conduction state to the first conduction state is the same as above, and will not be repeated here.

[0061] Optional, continue to refer to Figure 3As shown, the system also includes an alarm module 20; the alarm module 20 is electrically connected to the control module 2; the control module 2 is also used to control the alarm module 20 to alarm after the timing duration reaches a preset working duration, so that the switch module 1 switches between the first conduction state and the second conduction state.

[0062] The alarm module 20 is used to sound an alarm after the timing duration reaches a preset working duration.

[0063] Specifically, when the first oil distributor 4 is working, the control module 2 will control the timing module 10 to start timing. After the timing reaches the preset working time, the control module 2 needs to control the switch module 1 to switch between the first conduction state and the second conduction state. However, it is determined that the switch module 1 is still in the first conduction state, that is, the control module 2 has not switched successfully. Then, the control module 1 will control the alarm module 20 to alarm, and control the display module 8 to display the preset alarm information while the alarm is sounding. The preset alarm information may be "Oil single pipeline timeout", and the alarm sound may be "di di di" or "da da da" and other sounds that are easy for the staff to hear. At this time, after hearing the alarm sound, the staff can switch the switch module 1 between the first conduction state and the second conduction state by manual switching or other methods.

[0064] Optional, continue to refer to Figure 3 As shown, the control module 2 includes a storage unit 21, which is electrically connected to the oil detection module 6 and is used to store current state parameters of the oil.

[0065] Specifically, after the control module 2 receives the current state parameters of the oil, it will store the current state parameters of the oil in the storage unit 21, and can generate a chart or an online view based on the stored current state parameters of the oil. The chart can be used as a calibration chart. That is to say, the control module 2 can also determine whether the current state parameters of the oil are in a normal working state or an abnormal working state based on the trend information or parameter information of the current state parameters in the calibration chart.

[0066] Based on the same inventive concept, Figure 4 A flow chart of a method for switching an oil separator provided in an embodiment of the present invention, referring to Figure 4 As shown, the method is implemented based on the above-mentioned oil separator switching system, including:

[0067] S110. According to a preset switching condition, control the switch module to switch between a first conduction state and a second conduction state, so that when the switch module is in the first conduction state, oil is input into the diesel engine from the first port and the third port; when the switch module is in the second conduction state, oil is input into the diesel engine from the second port and the third port.

[0068] Specifically, when switching between the first oil separator and the second oil separator, one of the oil separators can be controlled to work first according to demand. Taking the operation of the first oil separator as an example, at this time, the control switch module is in the first conduction state, that is, the first port and the third port of the control switch module are connected, and the second port is in the disconnected state. At this time, after the oil separated in the first oil separator is input to the first port and the third port, it will flow to the diesel engine through the first port and the third port to ensure the normal operation of the diesel engine. When the preset switching condition is met, wherein the preset switching condition may be that the working time of the first oil separator reaches the preset time, or when the oil parameters in the diesel engine are abnormal, indicating that the first oil separator can no longer be controlled to provide oil at this time, and the oil separator needs to be switched, the control switch module is switched from the first conduction state to the second conduction state, that is, the second port and the third port are controlled to be conductive. At this time, the oil in the first oil separator will not flow to the third port after being input to the first port, and the oil separated in the second oil separator will flow to the diesel engine through the second port and the third port after being input to the second port, so as to realize the rapid switching between the first oil separator and the second oil separator. Similarly, when the operation of the second oil separator meets the preset switching condition, the control switch module is switched from the second conduction state to the first conduction state, that is, the first port and the third port are conductive, so as to switch from the operation of the second oil separator to the operation of the first oil separator.

[0069] The technical solution of the embodiment of the present invention controls the switch module to switch between the first conduction state and the second conduction state according to the preset switching condition, so that when the switch module is in the first conduction state, the oil is input to the diesel engine from the first port and the third port; when the switch module is in the second conduction state, the oil is input to the diesel engine from the second port and the third port. By using the above method, the switch module is switched between the first conduction state and the second conduction state, thereby switching between the operation of the first oil separator and the operation of the second oil separator is achieved, and the service life of the first oil separator and the second oil separator is extended.

[0070] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0071] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
