Detailed ways

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The core of this application is to provide a method, device and medium for conveying finished oil.

In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

FIG1 is a flow chart of a method for delivering finished oil provided in an embodiment of the present application. As shown in FIG1 , the method for delivering finished oil includes:

S10: When a request for delivery of refined oil is received, a target oil brand number and a target oil storage tank number are determined.

S11: calling a path finding algorithm, and using the path finding algorithm to determine a target oil transportation path according to a target oil brand number and a target oil storage tank number.

S12: Determine whether the valves corresponding to the oil delivery paths other than the target oil delivery path are closed; if not, execute step S13; if so, execute step S14.

S13: Generates a prompt that the valve is not closed.

S14: Generate a target valve opening instruction to control the opening of the target valve corresponding to the target oil delivery path so as to deliver the finished oil.

In step S10, receiving a delivery request for refined oil may be done by a staff member inputting a target oil brand number and a target oil storage tank number in the refined oil delivery system, or other methods, which are not specifically limited in the present embodiment. The number of target brand numbers and target oil storage tank numbers may be one or more, and one target brand number corresponds to one or more target oil storage tank numbers.

In step S11, the target oil transportation path is determined using a path algorithm according to the target brand number and the target oil storage tank number. Since one target oil brand number can correspond to one or more target oil storage tank numbers, and one oil storage tank number corresponds to one oil storage tank, the target oil transportation path can be one or more.

In step S12, it is checked whether there are valves in the oil delivery paths other than the target oil delivery path that are not closed. If there are, a prompt message is generated to remind the staff to perform relevant operations to close the valves in other oil delivery paths. The valves may include oil tank inlet valves, oil tank outlet valves, and pipeline rerouting valves, etc., and the embodiments of the present application do not specifically limit the valves.

In step S13, the embodiment of the present application does not specifically limit the form of the valve not-closed prompt.

In step S14, after determining the target oil delivery path, a target valve opening instruction is generated to control the opening of the target valve on the target oil delivery path. The target valve may include an oil tank inlet valve, an oil tank outlet valve, and a pipeline rerouting valve, etc., and the embodiment of the present application does not specifically limit the target valve.

A method for delivering refined oil provided in an embodiment of the present application includes: when a delivery request for refined oil is received, determining the target oil brand number and the target oil storage tank number; calling a path finding algorithm, and determining the target oil delivery path using the path finding algorithm according to the target oil brand number and the target oil storage tank number; judging whether the valves corresponding to other oil delivery paths other than the target oil delivery path are closed; if not, generating a prompt that the valve is not closed; if so, generating a target valve opening instruction to control the opening of the target valve corresponding to the target oil delivery path so as to deliver the refined oil. After determining the target oil brand number and the target oil storage tank number, the present application determines the target oil delivery path through a path finding algorithm, and after checking that the valves corresponding to other oil delivery paths are closed, generates a target valve opening instruction to control the opening of the target valve corresponding to the target oil delivery path, effectively avoiding the problem of easy errors in manually identifying the oil delivery path and opening the wrong valve, thereby improving the accuracy of determining the target oil delivery path and effectively avoiding the occurrence of oil mixing accidents.

Based on the above embodiments, after controlling the opening of the target valve corresponding to the target oil transportation path, the embodiment of the present application also includes: receiving the oil density in the main pipe fed back by the density meter; judging whether the oil density meets the preset density value; if so, generating a prompt that the oil interface has arrived at the distribution station.

The preset density value in the embodiment of the present application can be the density of different types of finished oil, and the preset density value can be determined when the target oil brand is determined. When the oil density detected by the density meter meets the preset density value, a prompt message is generated to prompt the staff that the oil interface has reached the distribution station. Compared with the need to manually observe the density meter and judge whether the oil interface has reached the distribution station, it effectively avoids the problem of staff making wrong judgments due to lack of experience or lack of responsibility.

Based on the above embodiments, after the oil product interface reaches the distribution station, the embodiments of the present application also include: determining whether the current download flow rate of the refined oil is less than the first preset download flow rate; if so, increasing the current download flow rate to the first preset download flow rate according to the preset flow increase curve.

In the embodiment of the present application, when the current download flow is less than the first preset download flow, the current download flow is increased to the first preset download flow according to the preset flow increase curve. The embodiment of the present application does not specifically limit the first preset download flow and the preset flow increase curve. For ease of understanding, the following example is given. For example, the first preset download flow is 50m ³ /h, the current download flow is 8m ³ /h, and the process of increasing the current download flow to the first preset download flow is described in conjunction with Figure 2. Figure 2 is a curve diagram of the initial download flow of an oil product provided in the embodiment of the present application. As shown in Figure 2, the horizontal axis represents time (minutes), and the vertical axis represents the ratio (%). At 0-2 minutes, the set download flow is 30% of the first preset download flow, that is, 15m ³ /h; at 3-5 minutes, the set download flow is 60% of the first preset download flow, that is, 30m ³ /h; after 6 minutes, the set download flow is 100% of the first preset download flow, that is, 50m ³ /h.

The embodiment of the present application can effectively avoid pressure fluctuations in the entire oil pipeline caused by a sharp increase in the flow rate of refined oil during transportation by slowly increasing the current download flow rate to the first preset download flow rate in a gradient manner, thereby avoiding water hammer accidents. At the same time, it also avoids the problem of improper human operation.

Based on the above embodiments, the implementation of the present application proposes that after increasing the current download flow rate to the first preset download flow rate according to the preset flow increase curve, it also includes: when the density meter detects that the finished oil is mixed oil, reducing the first preset download flow rate to the second preset download flow rate according to the preset flow reduction curve.

In the embodiment of the present application, when the density meter detects mixed oil, it means that the finished oil corresponding to the target oil brand is about to be transported, and another finished oil delivery begins. At this time, the first preset transport flow rate of the finished oil needs to be reduced to the second preset transport flow rate. For ease of understanding, an example is given. On the basis of the previous embodiment, the transport flow rate of the finished oil reaches 50m ³ /h. FIG3 is a curve diagram of the terminal transport flow rate of an oil product provided in the embodiment of the present application. As shown in FIG3, the horizontal axis represents time (minutes), and the vertical axis represents the ratio (%). In 0-2 minutes, the set transport flow rate is 100% of the first preset transport flow rate, that is, 50m ³ /h; in 3-5 minutes, the set transport flow rate is 60% of the first preset transport flow rate, that is, 30m ³ /h; after 6 minutes, the set transport flow rate is 30% of the first preset transport flow rate, that is, 15m ³ /h.

The embodiment of the present application can effectively avoid the pressure fluctuation of the entire oil pipeline caused by the sudden drop in the flow rate of the refined oil during transportation, and avoid the occurrence of water hammer accidents by slowly reducing the first preset download flow rate to the second preset download flow rate in a gradient manner. At the same time, it also avoids the problem of improper human operation.

Based on the above embodiments, after generating a target valve opening instruction to control the opening of the target valve corresponding to the target oil transmission path so as to transport the refined oil, the embodiment of the present application also includes: after reaching the preset total download volume, generating a target valve closing instruction to control the closing of the target valve corresponding to the target oil transmission path.

After the total download amount of each refined oil reaches the preset total download amount, the embodiment of the present application will automatically generate a target valve closing instruction to control the closing of the target valve corresponding to the target oil transportation path. Compared with manual judgment of when to open the target valve and when to close the target valve, the embodiment of the present application can effectively avoid the influence of human error in judgment. In addition, when there are many target valves, manually opening the valves one by one may cause the wrong valve to be opened, and the valve may be closed late or missed when closing. The embodiment of the present application automatically replaces manual work, which can effectively avoid the occurrence of the above phenomenon.

Based on the above embodiments, the embodiments of the present application also include, during the transportation process of refined oil, real-time monitoring of at least one of pipeline pressure, download flow, oil density, oil interface, pipeline valve status and oil tank liquid level, and obtaining real-time monitoring data; when the real-time monitoring data is abnormal, an alarm prompt is generated.

The embodiment of the present application also provides a monitoring system for real-time monitoring of pipeline pressure, download flow, oil density, oil interface, pipeline valve status and oil tank liquid level during the transportation of refined oil. When the real-time monitoring data is abnormal, an alarm prompt can be generated, such as an indicator light and/or a long buzzer sound. The embodiment of the present application does not specifically limit the method of the alarm prompt.

The embodiment of the present application monitors the equipment and process information and issues timely alarm prompts, which serves as a warning and also ensures the safety of finished oil transportation.
