Description

Technical Field

[0001] The present invention relates to the field of ship engineering technology, and in particular to a ship fuel consumption early warning method and system based on artificial intelligence analysis. Background Art

[0002] Ship fuel consumption warning is an important application in the field of ship engineering. It involves the design of operation data collection, processing, display and alarm system of ship equipment. By installing specific monitoring devices, such as flow sensor modules, wireless oil level detectors and sound and light alarm modules, real-time monitoring of ship fuel consumption can be achieved. These devices can detect diesel flow, calculate instantaneous and cumulative flow values, and display fuel consumption in real time on-site through LED digital tube display modules, so that management personnel can take timely measures to ensure the safety and efficiency of the ship. The fuel consumption of a ship is mainly the consumption of fuel during the operation of multiple engines in the ship. Usually, multiple engines share the same fuel tank, and each engine has different functions, such as anchoring, controlling driving power, and supplying power to the ship's power system.

[0003] The existing methods for early warning of fuel consumption of ships usually obtain the fuel consumption rate of the fuel under the ship state by selecting a preset measurement value, and obtain the speed corresponding to each fuel consumption rate through the relationship between the speed and the fuel consumption rate under the ship's running state, so as to monitor the fuel consumption of the ship and issue an early warning. Although this method can effectively monitor when the fuel consumption of the ship is abnormal, it can only monitor the fuel consumption of the ship under a stable driving state. When the ship's fuel tank is refueled or taken out of the oil tank, other than the ship's engine consumption, which causes changes in the ship's oil volume, the existing improved method will cause the problem of false early warnings. For example, in the publication number CN1057379 The patent application of 22A discloses a method and device for warning the fuel consumption rate of a low-speed diesel engine of a ship. The scheme is to give the fuel consumption rate under each typical speed condition. If the actual fuel consumption rate of the low-speed diesel engine under navigation deviates from the evaluation model ge(s) of the corresponding speed by more than a predetermined value, a warning is issued. Other methods for warning the fuel consumption of ships are usually based on theoretical values ​​for warning the fuel consumption. They still cannot solve the problem that the existing improved methods will cause false warnings when the fuel tank of the ship is refueled or oiled, etc., which causes changes in the fuel volume of the ship other than the consumption of the ship's engine. In view of this, it is necessary to improve the existing methods for warning the fuel consumption of ships. Summary of the invention

[0023] Furthermore, a wireless oil level detector is used to monitor the oil level in the ship's oil tank in real time, and obtaining a real-time oil volume curve based on real-time monitoring includes:

[0024] During the operation of the ship's engine, a wireless oil level detector is used to monitor the oil level in the ship's fuel tank in real time, and a power curve and an oil quantity curve are drawn in the fuel consumption analysis coordinate system based on the real-time power of the ship's engine and the monitoring results of the wireless oil level detector.

Finally, when the abnormal analysis is performed on the fuel tank oil level, an abnormal oil level warning is issued based on the oil change event. The advantage of this is that by obtaining the real-time oil quantity curve to determine whether to perform an abnormal analysis, it can be determined whether to perform further warning judgment based on the ratio fluctuation range when there is an abnormal fuel consumption ratio, thereby preventing the problem of erroneous warning caused by only issuing a warning based on the proportional relationship between the ship's engine and fuel consumption, thereby ensuring that the abnormal warnings issued by the abnormal analysis are all effective warnings.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1, first aspect, please refer to Figure 1 As shown, the present application provides a ship fuel consumption warning system based on artificial intelligence analysis, including a fuel consumption analysis module, an abnormal fuel consumption judgment module and an abnormal fuel consumption warning module;

[0048] The fuel consumption analysis module is used to place a wireless oil level detector in the ship's fuel tank, use the wireless oil level detector to obtain the oil level change data in the ship's fuel tank when the ship engine is in operation, and analyze the oil level change data, and obtain the fuel consumption ratio and the ratio fluctuation range based on the analysis results; the fuel consumption analysis module includes a fuel consumption ratio analysis unit, and the fuel consumption ratio analysis unit is configured with a fuel consumption ratio analysis strategy, and the fuel consumption ratio analysis strategy includes:

[0049] A wireless oil level detector is placed in the ship's oil tank, and the oil volume of the ship's oil tank detected by the wireless oil level detector is recorded as the ship's oil volume; a plane rectangular coordinate system is established, recorded as the engine analysis coordinate system, wherein the unit of the X-axis of the engine analysis coordinate system is time, and the unit of the Y-axis is power; the ship's engine is started, and the time for the ship's engine power to be continuously increased from 0 to the maximum power is recorded as the increase rate time, and the time for the ship's engine power to be continuously reduced from the maximum power to 0 is recorded as the decrease rate time;

[0050] The relationship between the real-time power and time of the ship engine during the rate increase time is obtained, and a corresponding curve is drawn in the engine analysis coordinate system, which is recorded as the rate increase curve; the relationship between the real-time power and time of the ship engine during the rate decrease time is obtained, and a corresponding curve is drawn in the engine analysis coordinate system, which is recorded as the rate decrease curve, wherein the starting point of the rate decrease curve is overlapped with the end point of the rate increase curve, and the obtained curve is recorded as the power curve;

[0051] In the specific implementation process, for example, during a data processing, the engine analysis coordinate system obtained can be found in Figure 3 As shown, curve QQ1 is the rate-up curve, the value corresponding to point XX1 is the rate-up time, the value corresponding to point YY1 is the maximum power of the ship engine, the value corresponding to point XX2 is the rate-down time, the value of point XX3 is the sum of the values ​​of point XX1 and point XX2, and curve QQ3 is the power curve; by obtaining the power curve, a schematic diagram of the rise and fall of the power of the ship engine under normal conditions can be obtained more intuitively, which is helpful to obtain the ratio between the power of the ship engine and the fuel consumption of the ship in subsequent analysis, so as to carry out early warning of ship fuel consumption.

[0052] Establish a plane rectangular coordinate system, recorded as the fuel tank consumption coordinate system, where the unit of the X-axis of the fuel tank consumption coordinate system is time, and the unit of the Y-axis is liter; obtain the relationship between the ship's fuel volume and time within the rising rate time, and draw a curve in the fuel tank consumption coordinate system, recorded as the rising oil curve; obtain the relationship between the ship's fuel volume and time within the falling rate time, and draw a curve in the fuel tank consumption coordinate system, recorded as the falling oil curve, where the starting point of the falling oil curve is overlapped with the end point of the rising rate curve, and the obtained curve is recorded as the fuel volume curve;

[0053] A plane rectangular coordinate system is established, which is recorded as the fuel consumption analysis coordinate system, wherein the unit of the X axis of the fuel consumption analysis coordinate system is time, and the unit of the Y axis is power or liter; the power curve and the fuel volume curve are placed in the fuel consumption analysis coordinate system, and the horizontal coordinate of the end point of the power curve and the fuel volume curve is marked as Q; in the specific implementation process, for example, during a data processing, the obtained fuel consumption analysis coordinate system can be referred to Figure 4 As shown, curve QQ4 is the power curve in the fuel consumption analysis coordinate system, and curve QQ5 is the fuel volume curve in the fuel consumption analysis coordinate system; by putting the power curve and the fuel volume curve into the same coordinate system, it is helpful to obtain the relationship between the engine power and the fuel volume at the same time, so that the fuel consumption ratio obtained by subsequent analysis is more in line with the actual operation of the ship, making the ship fuel consumption warning more accurate;

[0054] Divide the area between the origin of the fuel consumption analysis coordinate system and Q into k equal parts, and record them from left to right as fuel consumption part HY1 to fuel consumption part HY k In the specific implementation, the value of k can be determined according to the actual amount of data that can be analyzed. In this embodiment, the value of k is set to 10; for the fuel consumption HY1 to the fuel consumption HY k Any fuel consumption between HY k1 , use the fuel consumption ratio algorithm to obtain the fuel consumption HY k1 The fuel consumption ratio, the fuel consumption ratio algorithm is: Among them, F is the fuel consumption ratio, α max and α min Oil consumption is HY k1 The maximum and minimum slopes of the internal power curve; β max and β min Oil consumption is HY k1 The maximum value and the minimum value of the slope of the internal oil volume curve;

[0055] In the specific implementation process, for example, in a data processing process, the maximum value and the minimum value of the slope of the power curve in a fuel consumption portion HY are 2 and 1 respectively, and the maximum value and the minimum value of the slope of the fuel volume curve are 4 and 2 respectively. Then, through the fuel consumption ratio algorithm, it can be obtained that the fuel consumption ratio corresponding to the fuel consumption portion HY is 0; the fuel consumption ratio can be any value greater than or equal to 0. Considering that the fuel consumption of the actual ship continues to increase during operation, the denominator in the fuel consumption ratio algorithm is always greater than 0. When the fuel consumption is constant in the actual situation, the β in the fuel consumption ratio algorithm is min If it is 0, the fuel consumption ratio algorithm can be adjusted to prevent calculation errors from affecting subsequent analysis;

[0056] Get the fuel consumption ratio corresponding to all fuel consumption HYs;

[0057] The event in which the ship's oil quantity changes due to factors other than the ship's engine during the normal operation of the ship is recorded as an oil change event; for any oil change event, the ship's oil quantity at the time of the oil change event is recorded as the oil change oil quantity, the point whose ordinate of the oil quantity curve in the fuel consumption analysis coordinate system is the oil change oil quantity is recorded as the oil change point, the straight line parallel to the X-axis where the oil change point is located is recorded as the oil change straight line, and the ordinate of the point where the oil change straight line intersects the power curve is marked as the oil change power, where the oil change power corresponding to the same oil change point is not unique; in the specific implementation process, please refer to Figure 5 As shown, the value corresponding to point YB is the oil-to-oil amount, point YD is the oil-to-oil point, and the straight line YZ parallel to the X-axis where point YD is located is the oil-to-oil straight line. The oil-to-power at this time is the ordinate of point YG1 and the ordinate of point YG2. Therefore, the power corresponding to the same oil-to-oil point is not unique in actual analysis.

[0058] The ship's oil volume at the end of the oil change event is recorded as the oil change stop volume. Based on the change in the ship's oil volume during the oil change event, a curve is drawn from the oil change point to the right until the ordinate of the curve is the oil change stop volume. The obtained curve is recorded as the oil change curve. The oil change ratio algorithm is used to obtain the oil change ratio corresponding to the oil change event. The oil change ratio algorithm is: Among them, G is the oil change ratio, γ max and γ min is the maximum and minimum value of the slope of the power curve within the range of the abscissa of the oil variation curve, δ max and δ min is the maximum value and minimum value of the slope of the oil change curve; in the specific implementation process, for example, in a data processing process, the maximum value and minimum value of the slope of the power curve within the range of the horizontal coordinate of the oil change curve are 2 and -1 respectively, and the maximum value and minimum value of the slope of the oil change curve are 4 and 2 respectively, then it can be obtained by calculation that the oil change ratio corresponding to the oil change event of the oil change curve is 4; by obtaining the oil change ratio, it is possible to obtain the proportional relationship between the power of the ship engine and the ship's fuel consumption when the oil change occurs, and then obtain the interval of the influence of different events on the fuel consumption ratio when the ship's fuel tank is refueled or taken out of the oil tank other than the ship's engine consumption, so as to prevent the problem of false warning caused by warning only by the proportional relationship between the ship engine and the fuel consumption;

[0059] The oil consumption portion HY that coincides with the oil variation curve is recorded as the oil variation portion, and the ratio fluctuation range of the oil consumption ratio of the oil variation portion is set to [t1, t2], where t1 is the oil consumption ratio minus the oil variation ratio, and t2 is the oil consumption ratio plus the oil variation ratio; in the specific implementation process, for example, in a data processing, the oil consumption ratio of the oil variation portion is 0, and the oil variation ratio is 4, then the ratio fluctuation range of the oil variation portion can be obtained by calculation as [-4, 4];

[0060] The oil change ratios corresponding to all oil change events are obtained, wherein the same oil consumption portion HY can be recorded as the oil change portions corresponding to multiple oil change events.

[0061] The abnormal fuel consumption judgment module is used to use a wireless fuel level detector to monitor the fuel level in the ship's fuel tank in real time during the operation of the ship's engine, obtain a real-time fuel volume curve based on real-time monitoring, and analyze the real-time fuel volume curve based on the fuel consumption ratio and the ratio fluctuation range. The analysis result determines whether to perform an abnormal analysis on the fuel tank fuel level;

[0062] The abnormal fuel consumption judgment module includes an abnormal analysis unit, which is configured with an abnormal analysis strategy. The abnormal analysis strategy includes: during the operation of the ship's engine, the wireless oil level detector is used to monitor the oil level in the ship's fuel tank in real time, and based on the real-time power of the ship's engine and the monitoring results of the wireless oil level detector, a power curve and an oil quantity curve are drawn in the fuel consumption analysis coordinate system, and the power curve at this time is recorded as the real-time power curve, and the oil quantity curve at this time is recorded as the real-time oil quantity curve; the value of Q divided by k is recorded as the monitoring interval, and the real-time monitoring time of the wireless oil level detector passes through each monitoring interval, and the fuel consumption ratio algorithm is used to obtain the fuel consumption ratio corresponding to the real-time monitoring curve and the real-time oil quantity curve in the latest monitoring interval, which is recorded as the real-time fuel consumption ratio;

[0063] In the specific implementation process, the value of Q is 100min, the value of k is 10, and the monitoring interval is 10min through calculation. Then, during the operation of the ship's engine, the real-time monitoring time of the oil level detector is 10min, and the fuel consumption ratio algorithm is used to obtain the fuel consumption ratio corresponding to the real-time monitoring curve and the real-time fuel volume curve within the most recent 10min, which is recorded as the real-time fuel consumption ratio;

[0064] The curve corresponding to the latest monitoring interval in the real-time power curve is recorded as the monitoring power curve, the interval formed by the maximum and minimum values ​​of the ordinate of the monitoring power curve is recorded as the real-time power interval, the interval formed by the maximum and minimum values ​​of the ordinate of the fuel consumption HY is recorded as the fuel consumption power interval, the fuel consumption HY with the largest overlap area between the fuel consumption power interval and the real-time power interval is recorded as the real-time fuel consumption, and the fuel consumption ratio of the real-time fuel consumption is recorded as the comparison ratio;

[0065] When the comparison ratio is equal to the real-time fuel consumption ratio, the fuel tank oil level is recorded as the normal fuel level; in specific implementation, when the comparison ratio is equal to the real-time fuel consumption ratio, it means that the fuel consumption of the ship is normal; when the comparison ratio is not equal to the real-time fuel consumption ratio, it means that the fuel consumption of the ship is abnormal.
