[0039] In an embodiment, Figure 1 A structure diagram of a switching system of an oil separator provided in an embodiment of the present application is shown in FIG. 1. The present embodiment can be applied to the case of improving the service life of a first oil separator and a second oil separator arranged on a ship, 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 in communication with the first port of the switch module 1; the second oil separator 5 is in communication with the second port of the switch module 1, and the diesel engine 3 is in communication with the third port of the switch module 1; the control module 2 is electrically connected with the switch module 1; the first oil separator 4 is used for inputting oil to the first port; the second oil separator 5 is used for inputting 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 in conduction, and the second conduction state is that the second port and the third port are both in conduction; the control module 2 is used for controlling 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, oil is input from the first port and the third port to the diesel engine 3; and when the switch module 1 is in the second conduction state, 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 in which the first port and the third port are in communication is a first kind of flow pipeline, and the pipeline in which the second port and the third port are in communication is a second kind of flow pipeline. The switch module 1 is used for controlling oil to flow in one of the flow pipelines. In this embodiment, the switch module 1 can include but is not limited to a three-way valve. The first oil separator 4 and the second oil separator 5 are a kind of centrifugal sedimentation equipment, mainly used on ships, and the core function thereof is to separate water, impurities and particles in fuel oil and lubricating oil to ensure the purity of oil. The working principle of the first oil separator 4 and the second oil separator 5 is centrifugal separation technology, which separates oil, water and impurities according to different density distribution by centrifugal force generated by high-speed rotation, so as to realize separation. The oil separated in the first oil separator 4 is input to the first port of the switch module 1, and the oil separated in the second oil separator 5 is 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 for controlling the switch module 1 to switch between the first conduction state and the second conduction state according to a preset switching condition. The first conduction state is that the first port and the third port of the switch module 1 are in conduction, and the second conduction state is that the second port and the third port of the switch module 1 are in conduction. And when the switch module 1 is in the first conduction state, only the oil in the first oil separator 4 can flow to the diesel engine 3; and when the switch module 1 is in the second conduction state, only the oil in the second oil separator 5 can flow to the diesel engine 3.

[0041] Specifically, when the first oil separator 4 and the second oil separator 5 are switched, one of them can be controlled to work according to the needs. Taking 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 in communication with the first port of the switch module 1, and the diesel engine 3 is in communication with 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 in communication, that is, the switch module 1 is in the first communication state, and the second port is in the disconnected state. After the oil separated by the first oil separator 4 is input to the first port and the third port, it is circulated to the diesel engine 3 through the first port and the third port, so as to ensure the normal work of the diesel engine 3. When the preset switching condition is met, the preset switching condition can be that the working time of the first oil separator 4 reaches the preset time, or the current state parameter of the oil in the diesel engine 3 is abnormal, indicating that the first oil separator 4 cannot continue to work to provide oil to the diesel engine 3 at this time, and the oil separator needs to be switched. Then the control module 2 controls the switch module 1 to switch from the first communication state to the second communication state, that is, the second port and the third port are in communication, and the first port is disconnected. Because the second oil separator 5 is in communication with the second port of the switch module 1, when the second port and the third port are in communication and the first port is disconnected, the oil in the first oil separator 4 will not be circulated to the third port after being input to the first port. After the oil separated by the second oil separator 5 is input to the second port, it is circulated to the diesel engine 3 through the second port and the third port, so as to realize the quick switching between the first oil separator 4 and the second oil separator 5. Similarly, when the working of the second oil separator 5 meets the preset switching condition, the control module 2 controls the switch module 1 to switch from the second communication state to the first communication state, that is, the first port and the third port of the switch module 1 are in communication. At this time, the oil separated by the second oil separator 5 will not be circulated to the diesel engine 3, and the oil separated by the first oil separator 4 will be circulated to the diesel engine through the first port and the third port, so as to realize the switching between the second oil separator 5 and the first oil separator 4.

[0042] The technical scheme of the embodiment of the present application comprises the following steps: the switch module is provided, the switch module comprises a first communication state and a second communication state, when the switch module is in the first communication state, the oil separated by the first oil separator is circulated to the diesel engine through the first port and the third port; when the switch module is in the second communication state, the oil separated by the second oil separator is circulated to the diesel engine through the second port and the third port; when the first oil separator or the second oil separator works, the control module controls the switch module to switch between the first communication state and the second communication state according to the preset switching condition, so that the oil separated by the first oil separator or the second oil separator is circulated to the diesel engine. By using the above structure, the quick 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 prolonged.

[0043] Optionally, Figure 2 The second oil separation machine switching system provided by the embodiment of the present application is shown in the structure diagram, and the system further comprises an oil detection module 6; the oil detection module 6 is electrically connected with the diesel engine 3 and the control module 2 respectively; the oil detection module 6 is used for detecting the current state parameter of the oil entering the diesel engine 3; the control module 2 is further used for receiving the current state parameter of the oil and determining the state of the oil in combination with the preset state parameter condition; when the oil is in an abnormal state, the control switch module 1 is switched between the first conduction state and the second conduction state. Figure 2

[0044] The oil detection module 6 is used for detecting the current state parameter of the oil input to the diesel engine 3 and sending the current state parameter of the oil to the control module 2.

[0045] Specifically, after the oil in the first oil separation machine 4 or the second oil separation machine 5 flows to the diesel engine 3, the oil detection module 6 connected with the diesel engine 3 detects the current state parameter of the oil in real time and sends the detected current state parameter to the control module 2. After the control module 2 receives the current state parameter of the oil, according to the current state parameter and in combination with the parameter threshold corresponding to the current state parameter, when the current state parameter of the oil is outside the corresponding threshold, it indicates that the current state parameter of the oil is 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 separation machine cannot meet the normal use requirement, then the control module 2 controls the switch module 1 to switch from the first conduction state to the second conduction state, so as to switch from the first oil separation machine 4 to the second oil separation machine 5; or the control module 2 controls the switch module 1 to switch from the second conduction state to the first conduction state, so as to switch from the second oil separation machine 5 to the first oil separation machine 4.

[0046] In another specific embodiment, optionally, the current state parameter of the oil at least includes the particle content, the particle concentration and the pressure of the oil; the control module 2 is further used for determining that the oil is in an abnormal state when 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.

[0047] ​Specifically, the control module 2 receives the current state parameters of the oil, which can include the particle content, the particle concentration and the pressure of the oil. When it is determined that the particle content 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, it indicates that the oil is too dirty, and the oil is in an abnormal state. Therefore, the control module 2 controls the switch module 1 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 a preset content threshold, it indicates that the oil is too little to flow into the diesel engine 3, i.e., the oil is not in place, and the oil is in an abnormal state.

[0048] It should be noted that, when determining the dirtiness of the oil, at least one of the particle content, the particle concentration and the pressure of the oil can be used to determine the dirtiness of the oil. Generally, when the detection requirement is low, the pressure of the oil can be directly used to determine the dirtiness of the oil. When the pressure of the oil is lower than the preset pressure threshold, it can be determined that the oil is dirty. However, in actual operation, in order to improve the accuracy of detection and avoid misjudgment, the particle content and the particle concentration of the oil are also detected. When the pressure of the oil is lower than the preset pressure threshold, the 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 in an abnormal state.

[0049] Optionally, with reference to Figure 2 , the system further comprises a manual valve 7; the manual valve 7 is electrically connected to the oil detection module 6, and the manual valve 7 is communicated between the oil detection module 6 and the diesel engine 3; the oil detection module 6 is further configured to confirm that the manual valve conduction instruction generated when the user rotates the manual valve 7 is received before detecting the current state parameters of the oil entering the diesel engine 3.

[0050] The manual valve 7 is a valve that needs to be manually operated to control the flow of fluid (such as liquid, gas, etc.). It is usually used in pipeline systems to open or close the flow of fluid, or to adjust the flow and pressure of fluid. In this embodiment, the manual valve 7 is communicated 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 to enable the oil detection module 6 to detect the oil in the diesel engine 3. That is, before the oil detection module 6 detects the current state parameters of the oil in the diesel engine 3, it needs to confirm that the manual valve conduction instruction generated when the user rotates the manual valve 7 to the conduction position is received. After receiving the manual valve conduction instruction, it indicates that the user has rotated the manual valve 7 to the conduction position, and then the current state parameters of the oil in the diesel engine 3 are detected.

[0051] Optionally, with reference to the above Figure 2 The system further comprises a display module 8; the display module 8 is electrically connected with the control module 2; the control module 2 is configured to control the display module 8 to display the current state parameter after receiving the current state parameter.

[0052] The display module 8 is configured to display the current state parameter of the oil. The display module 8 can include, but is not limited to, a display screen, a liquid crystal screen, a projector or other devices that can be used for display. In the embodiment, the display module 8 comprises a local display unit and a remote display unit. The local display unit is configured to display the current state parameter of the oil near the control module 8, and the remote display unit is configured to display the current state parameter of the oil remotely, such as in an office or a laboratory. To ensure adaptability, the remote display unit can be connected with the control module 2 through an adapter, such as a server. The control module 2 is configured to display the current state parameter on the display module 8 after receiving the current state parameter, so as to allow a user to view the current parameter result.

[0053] In addition, the current state parameter of the oil further comprises an oil pressure and an oil temperature, and the display module 8 can further display the oil pressure and the oil temperature detected by the oil detection module 6, so as to allow a user to view the oil pressure and the oil temperature.

[0054] Optionally, with reference to the above Figure 2 The system further comprises a valve feedback 9 and an opening limit plate (not shown in the figure), and the valve feedback 9 is electrically connected with the opening limit plate and the control module 2; the valve feedback 9 is configured to generate a first conduction success signal when the first port and the third port reach the limit of the opening limit plate; the control module 2 is further configured to confirm that the first conduction success signal is received when the control switch module 1 is in the first conduction state; the valve feedback 9 is further configured to generate a second conduction success signal when the second port and the third port reach the limit of the opening limit plate; and the control module 2 is further configured to confirm that the second conduction success signal is received when the control switch module 1 is in the second conduction state.

[0055] Wherein, the valve feedback 9 refers to monitoring the actual position state of the valve or switch in the industrial automation control system through a specific sensor or feedback device. In the embodiment, an open limit plate is also provided, which is located at the limit position of the first port, the second port and the third port of the switch module 1, and is electrically connected with 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 conducted, at this time, when the first port and the third port are both conducted to the limit position 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 the receipt of the first conduction success signal sent by the valve feedback 9, indicating that the first port and the third port are conducted 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 conducted, at this time, when the second port and the third port are both conducted to the limit position 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 the receipt of the second conduction success signal sent by the valve feedback 9, indicating that the second port and the third port are conducted in place.

[0056] It should be noted that the system can also be provided with a close limit plate, which is electrically connected with 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 generate a first conduction success signal when the second port is closed to the close limit plate, in addition to generating the first conduction success signal when the first port and the third port are both conducted to the limit position of the open limit plate. The control module 2 will confirm the receipt of the first conduction success signal and the first close success signal when controlling the switch module 1 to be in the first conduction state. Similarly, when the control module 2 controls the switch module 1 to be in the second conduction state, the valve feedback 9 will generate a second close success signal when the first port is closed to the close limit plate, in addition to generating the second conduction success signal when the second port and the third port are both conducted to the limit position of the open limit plate. The control module 2 will confirm the receipt of the second conduction success signal and the second close success signal when controlling the switch module 1 to be in the second conduction state, to determine whether the port is conducted or closed in place.

[0057] Optionally, Figure 3 The third oil distributor switching system structure schematic diagram provided by the embodiment of the application is shown in reference Figure 3As shown, the system further comprises a timing module 10; the timing module 10 is electrically connected with the control module 2; the control module 2 is further configured to control the timing module 10 to start timing while the switching module 1 is in the first conducting state, and control the switching module 1 to switch to the second conducting state when the timing duration reaches the preset working duration; control the timing module 10 to start timing while the switching module 1 is in the second conducting state, and control the switching module 1 to switch to the first conducting state when the timing duration reaches the preset working duration.

[0058] The timing module 10 is configured to start timing when the first conducting state or the second conducting state starts.

[0059] Specifically, when the control module 2 controls the switching module 1 to be in the first conducting state, the control module 2 controls the timing module 10 to start timing, and at this time, the first oil separator 4 starts working. When the timing duration reaches the preset working duration, it indicates that the working duration of the first oil separator 4 reaches the preset working duration, and the first oil separator 4 cannot continue to work, so the oil separator needs to be switched to ensure the service life of the first oil separator 4. Therefore, the control module 2 controls the switching module 1 to switch to the second conducting state, so that the second oil separator 5 works. Similarly, when the control module 2 controls the switching module 1 to be in the second conducting state, the control module 2 controls the timing module 10 to start timing, and at this time, the second oil separator 5 starts working. When the timing duration reaches the preset working duration, it indicates that the working duration of the second oil separator 5 reaches the preset working duration, and the second oil separator 5 cannot continue to work, so the oil separator needs to be switched to ensure the service life of the second oil separator 5. Therefore, the control module 2 controls the switching module 1 to switch to the first conducting state, so that the first oil separator 4 works.

[0060] It should be noted that when the control module 2 controls the switching module 1 to be in the first conducting state and controls the timing module 10 to start timing, the oil detection module 6 also detects the current state parameters of the oil in the diesel engine 3 in real time and sends them to the control module 2. When the control module 2 determines that the oil is abnormal within the preset working duration, the control module 2 does not need to wait for the first oil separator 4 to work to the preset working duration, but directly controls the switching module 1 to switch from the first conducting state to the second conducting state. When the control module 2 determines that the oil is normal within the preset working duration, the control module 2 controls the switching module 1 to switch to the second conducting state to make the second oil separator 5 work only after the working duration of the first oil separator 4 reaches the preset working duration. For example, the preset working duration is 24 hours. Similarly, the logic of the control module 2 controlling the switching module 1 to switch from the second conducting state to the first conducting state is the same as the above, which will not be described here.

[0061] Optionally, continuing to refer to Figure 3As shown, the system further comprises an alarm module 20; the alarm module 20 is electrically connected with the control module 2; the control module 2 is further configured to control the alarm module 20 to alarm after the timing duration reaches the preset working duration, so as to control the switch module 1 to switch between the first conduction state and the second conduction state.

[0062] The alarm module 20 is configured to alarm after the timing duration reaches the preset working duration.

[0063] Specifically, when the first oil distributor 4 is working, the control module 2 controls the timing module 10 to start timing, and after the timing duration reaches the preset working duration, the control module 2 needs to control the switch module 1 to switch between the first conduction state and the second conduction state, but at this time it is determined that the switch module 1 is still in the first conduction state, that is, the control module 2 fails to switch successfully, then the control module 1 controls the alarm module 20 to alarm, and controls the display module 8 to display the preset alarm information at the same time, wherein the preset alarm information can be "single oil line timeout", and the alarm sound can be "ticking" or "clicking" and the like which can be easily heard by the staff, at this time the staff can switch the switch module 1 between the first conduction state and the second conduction state through manual switching or the like after hearing the alarm sound.

[0064] Optionally, continuing to refer to Figure 3 As shown, the control module 2 comprises a storage unit 21, the storage unit 21 is electrically connected with the oil detection module 6, and is configured to store the current state parameter of the oil.

[0065] Specifically, after the control module 2 receives the current state parameter of the oil, the control module 2 stores the current state parameter of the oil in the storage unit 21, and can generate a chart or an online view according to the stored current state parameter of the oil, the chart can be used as a calibration chart, that is, the control module 2 can also determine that the current state parameter of the oil is in a normal working state or an abnormal working state according to trend information or parameter information of the current state parameter in the calibration chart.

[0066] Based on the same inventive concept, Figure 4 A flowchart of a method for switching an oil distributor is provided for the embodiment of the present application, referring to Figure 4 As shown, the method is implemented based on the above-mentioned oil distributor switching system, and comprises the following steps:

[0067] S110, according to the preset switching condition, the switch module is controlled to switch between the first conduction state and the second conduction state, 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; and 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.

[0068] Specifically, when the first oil separator and the second oil separator are switched, one of them can be controlled to work according to the requirement. Taking the first oil separator as an example, 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 in conduction, and the second port is in the off state. At this time, the oil separated from the first oil separator is input to the first port and the third port, and then flows to the diesel engine through the first port and the third port, so as to ensure the normal work of the diesel engine. When the preset switching condition is met, the preset switching condition can be that the working time of the first oil separator reaches the preset time, or the oil parameter in the diesel engine is abnormal, which indicates that the first oil separator cannot continue to work to provide oil at this time, and the oil separator needs to be switched. Then, 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 in conduction. At this time, the oil in the first oil separator is not input to the third port after being input to the first port, and the oil separated from the second oil separator is input to the second port and then flows to the diesel engine through the second port and the third port, so as to realize the quick switching between the first oil separator and the second oil separator. Similarly, when 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 in conduction, so as to switch from the second oil separator to the first oil separator.

[0069] The technical scheme of the embodiment of the present application is that the control switch module is switched between the first conduction state and the second conduction state according to the preset switching condition, so that when the control switch module is in the first conduction state, the oil is input to the diesel engine from the first port and the third port, and when the control 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 switching of the control switch module between the first conduction state and the second conduction state is realized, so as to realize the switching between the working of the first oil separator and the working of the second oil separator, and the service life of the first oil separator and the second oil separator is prolonged.

[0070] It should be understood that the various forms of flow shown above can be reordered, additional steps added, or steps deleted. For example, the steps described in the present application can be executed in parallel, in series, or in a different order, as long as the desired results of the technical scheme of the present application can be achieved, which is not limited herein.

[0071] The above specific embodiments do not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
