FIG. 1 shows a schematic diagram of a ship according to an embodiment of the present invention.
The ship 1 is, for example, a container ship, and includes a hull 100 that is a main body of the ship 1, a power generation unit 200, a computer device 300, and a measurement device 400. The power generation unit 200 is provided in the hull 100 and generates power for rotating a propeller provided on the stern side. The power generation unit 200 of the present embodiment includes a main engine 210 that is an internal combustion engine such as a diesel engine, a supercharger 220 that draws pressurized gas into the main engine 210 and is driven by exhaust gas from the main engine 210, and a main engine 210. A load acquisition unit 230 that acquires data on the load (main machine load). In the present application, the load of the main engine means a work amount per unit time of the main engine (internal combustion engine). The power generation unit 200 also has a function as a data logger. The computer device 300 is a computer device provided in the hull 100 and disposed in a residential area 310 where sailors are active. The measuring device 400 includes, for example, an anemometer, a barometer, a thermometer, a rain gauge, and a wave height meter, and identifies weather and sea conditions (hereinafter referred to as “meteorological sea conditions”) during the navigation of the ship 1. Measure the data. In addition, the measuring device 400 measures data for specifying information (navigation information) related to the voyage from the departure point of the ship 1 to the destination, such as the average ship speed, the cruising distance, and the fuel consumption.

FIG. 2 is a diagram showing a configuration of the supercharger 220 and its surroundings. Hereinafter, the configuration of the supercharger 220 will be described with reference to FIG.
The turbine 221 rotates the compressor (compressor) 222 using the energy of the exhaust gas from the main engine 210. When the compressor 222 is rotationally driven by the turbine 221, it sucks and pressurizes outside air. The scavenging receiver 223 is arranged immediately before the main unit 210, and when pressurized gas is supplied from the compressor 222, the scavenging receiver 223 temporarily stores the pressurized gas. The scavenging receiver 223 sends the stored pressurized gas into the cylinder of the main unit 210. The main engine 210 burns in the cylinder based on the pressurized gas supplied from the scavenging receiver 223, converts heat energy into kinetic energy, and generates power. The exhaust receiver 224 is disposed immediately after the main unit 210 and temporarily stores the exhaust gas generated by the combustion of the main unit 210. The exhaust receiver 224 sends exhaust gas into the exhaust pipe 225. The exhaust gas is supplied from the exhaust pipe 225 to the turbine 221, drives the turbine 221, and is discarded outside the supercharger 220.

The supercharger 220 further includes an outside air temperature sensor 231A disposed in the vicinity of the outside air intake port of the compressor 222 (ie, the inlet of the supercharger 220), and a scavenging pressure sensor 231B disposed in the scavenging receiver 223. , And an exhaust temperature sensor 231C disposed in the exhaust pipe 225. The outside air temperature sensor 231A is a sensor that measures the temperature of outside air (that is, the outside air temperature) sucked by the compressor 222, and outputs data indicating the measurement result of the outside air temperature. The scavenging pressure sensor 231B is a sensor that measures the scavenging pressure of the pressurized gas sent from the supercharger 220 to the main engine 210, and outputs data indicating the scavenging pressure measurement result. The exhaust temperature sensor 231C is a sensor that measures the exhaust temperature of the supercharger 220, and outputs data indicating the measurement result of the exhaust temperature.
The scavenging pressure sensor 231 </ b> B only needs to measure the scavenging pressure of the pressurized gas sent from the supercharger 220 to the main unit 210, and may be disposed in a conduction pipe that connects the scavenging receiver 223 and the main unit 210, for example. . The exhaust temperature sensor 231 </ b> C only needs to measure the exhaust temperature of the supercharger 220, and may be disposed in the exhaust receiver 224, for example. For example, the load acquisition unit 230 acquires scavenging pressure data of the supercharger 220 as load data of the main unit 210. Since various data (including the scavenging pressure) of the main engine 210 are measured and recorded during the trial operation when the ship 1 is built, the approximate load on the main engine 210 is estimated by comparison with the scavenging pressure during the trial operation. Is possible. The scavenging pressure is an index of the load on the main engine 210. Then, the load acquisition unit 230 outputs the acquired (estimated) load data.

FIG. 3 is a block diagram illustrating a configuration of the computer apparatus 300.
The computer device 300 functions as an output device that outputs data indicating the deterioration of the supercharger 220 over time. The computer apparatus 300 includes a control unit 301, a storage unit 302, a display unit 303, an input / output unit 304, a communication unit 305, and an operation unit 306. The control unit 301 is a microcomputer having a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM) as an arithmetic processing unit. The CPU controls each unit of the computer apparatus 300 by reading the program stored in the ROM or the storage unit 302 into the RAM and executing the program. The control unit 301 realizes functions corresponding to the acquisition unit 301A and the output unit 301B. The acquisition unit 301 </ b> A is a unit that acquires data from the power generation unit 200 and the measurement device 400. For example, the acquisition unit 301A acquires the scavenging pressure of the supercharger 220, the exhaust temperature of the supercharger 220, the outside air temperature, and the load of the main unit 210 for each of a plurality of time points. Further, the acquisition unit 301 </ b> A acquires data obtained by measuring disturbance elements acting on the supercharger 220 and fuel consumption of the main engine 210. Based on the data acquired by the acquisition unit 301A, the output unit 301B outputs changes over time in the scavenging pressure and the exhaust temperature according to the load within a predetermined range. The output unit 301 </ b> B may reflect the disturbance element acting on the supercharger 220 and the fuel consumption data of the main engine 210 in the output.

  The storage unit 302 is a hard disk device, for example, and stores a program for operating the computer device 300 and a table T. As shown in FIG. 4, the table T is a table in which scavenging pressure, exhaust temperature, outside air temperature, and date / time data indicating the date / time of measurement or acquisition thereof are stored in association with each other for each load zone of the main engine 210. The load band in the table T indicates each range when the entire range of the load of the main unit 210 is divided into a plurality of stages for each predetermined range (for example, every 10%). For example, when the maximum load value is set to 100% and divided every 10%, each range divided every 10% is set as a load band. The display unit 303 is a liquid crystal display, for example, and displays various types of information. The input / output unit 304 is an interface for inputting / outputting data between the power generation unit 200 and the measurement device 400. The input / output unit 304 receives load data from the load acquisition unit 230, data from the outside air temperature sensor 231 </ b> A, the scavenging pressure sensor 231 </ b> B, and the exhaust gas temperature sensor 231 </ b> C, and measurement data indicating measurement results from the measurement device 400. The The communication unit 305 includes, for example, a communication circuit and an antenna for connecting to a network, and communicates with a computer device installed on land via the network. The operation unit 306 includes, for example, a keyboard and a mouse, and receives an operation performed by an operator (here, a sailor).

FIG. 5 is a flowchart illustrating processing executed by the computer apparatus 300. For example, the computer device 300 executes the processing shown in FIG. 5 periodically or in response to an instruction from a sailor.
First, the control unit 301 of the computer device 300 acquires measurement data from the measurement device 400 (step S1). Next, the control unit 301 determines whether to collect data from the power generation unit 200 (step S2). The control unit 301 specifies the weather and sea conditions at the current position based on the measurement data from the measurement device 400. The control unit 301 determines that data is collected from the power generation unit 200 when it is not stormy weather (for example, during fine weather), and determines that data is not collected from the power generation unit 200 during stormy weather. In addition to the method of using the measurement data, the control unit 301 may acquire data on the weather and sea conditions via the communication unit 305 and specify the weather and sea conditions at the current position.

  When it is determined that data is to be collected (step S2; YES), the control unit 301 receives each data from the outside air temperature sensor 231A, the scavenging pressure sensor 231B, and the exhaust temperature sensor 231C via the input / output unit 304. 200 (step S3). Next, the control unit 301 acquires load data of the main unit 210 from the power generation unit 200 via the input / output unit 304 (step S4). Next, the control unit 301 associates each data of the scavenging pressure, the exhaust temperature and the outside air temperature acquired in step S3, and date and time data with a load band including the load indicated by the load data acquired in step S4. Store in the table T (step S5). In the table T, for example, data collected every several months or years is stored. Next, the control unit 301 outputs changes over time in the scavenging pressure and the exhaust temperature for each load zone of the main engine 210 based on the table T (step S6).

FIG. 6 is a graph showing an example of changes over time in the scavenging pressure and the exhaust temperature of the pressurized gas sent from the supercharger 220 to the main engine 210 in a certain load zone. In the graph of FIG. 6, the horizontal axis represents time, and the vertical axis represents scavenging pressure or exhaust temperature. FIG. 6 shows the moving average of the scavenging pressure and the exhaust temperature, that is, the average value for each unit period.
In the period I shown in FIG. 6, the change with time of the scavenging pressure and the exhaust temperature is small. That is, when the main engine 210 is in a certain load zone, the scavenging pressure and the exhaust temperature are maintained in a substantially constant state. In this case, the degree of aging of the supercharger 220 is small, and it is estimated that the supercharger 220 is operating normally. On the other hand, in the period II shown in FIG. 6, the scavenging pressure decreases while the exhaust gas temperature increases. In this case, it is estimated that the degree of aging of the supercharger 220 is greater than the period I. One reason for this is that the energy conversion efficiency of the main engine 210 is deteriorated when the scavenging pressure decreases and the exhaust temperature increases during a certain load zone. As an example of the cause of aging deterioration of the function of the supercharger 220, there is wear of the inner periphery of the cover ring in the turbine 221, wear of the blade tip, and accumulation of the scale of the nozzle ring.

Next, an output example in step S6 will be described.
The control unit 301 outputs, to the display unit 303, an image that visually represents changes over time in the scavenging pressure and the exhaust temperature, for example, display data for displaying the graph shown in FIG. In other words, this display data is data for displaying a graph showing a change in exhaust temperature over time and a graph sharing a time axis with the graph and showing a change in scavenging pressure over time. In this case, the sailor who saw the display content of the display unit 303 grasps the degree of deterioration of the supercharger 220 over time, and whether or not maintenance (for example, cleaning or replacement of parts) of the supercharger 220 is necessary or not. The time can be judged. For example, as in the period II, a sailor who confirms that the scavenging pressure is decreasing and the exhaust temperature is increasing determines that maintenance of the supercharger 220 should be performed.

  As another output example, the control unit 301 may output data indicating the degree of aging deterioration of the supercharger 220 based on data during a period in which the scavenging pressure decreases and the exhaust temperature increases. As this data, there is data (hereinafter referred to as “notification data”) for notifying the degree of deterioration over time. The notification data is data for reporting the degree of aging deterioration of the supercharger 220 by, for example, a method that can be perceived by a human. As an example of the notification method, there are display on the display unit 303, output of an alarm sound, lighting of a lamp, and the like. The notification data is output, for example, when a condition for performing maintenance of the supercharger 220 is satisfied.

The output condition of the notification data will be described. For example, the control unit 301 is based on the condition that the amount of decrease in the scavenging pressure in a predetermined period is equal to or greater than a threshold and the amount of increase in the exhaust temperature in the predetermined period is equal to or greater than the threshold. Notification data is output. The output condition of the notification data may be the same regardless of the type of the ship or the supercharger, or may be set for each type of the ship or the supercharger. In addition, the control unit 301 may output notification data when the output condition is satisfied in any one load band, or output the notification data when the output condition is satisfied in two or more load bands. May be.
Note that the output destination of the notification data is not limited to the device arranged in the ship 1. For example, the control unit 301 may transmit notification data to a computer device installed on land such as a dock via the communication unit 305.

As another output example, there is an output example described below.
Even when the supercharger 220 operates normally, if the outside air temperature rises during the period in which the scavenging pressure has fallen, the exhaust gas temperature may rise. On the other hand, even if the aging deterioration appears in the supercharger 220, the exhaust temperature may not rise when the outside air temperature falls during the period in which the scavenging pressure is lowered. Thus, changes over time in scavenging pressure and exhaust temperature may be affected by disturbances. Therefore, the control unit 301 may reflect data of disturbance elements acting on the supercharger 220 in the output.

For example, the control unit 301 reflects external temperature data in the output as a disturbance factor. When outputting the notification data described above, the control unit 301 may use, as a notification data output condition, that the increase amount of the exhaust temperature is larger than the increase amount of the outside air temperature during the period in which the scavenging pressure is decreased.
Further, the control unit 301 may correct the exhaust temperature based on the outside air temperature data, and output based on the corrected exhaust temperature. The correction algorithm is not particularly limited. For example, correction is performed by subtracting a value obtained by multiplying the outside air temperature by a predetermined coefficient from the exhaust temperature. Thereby, the influence on the output by the fluctuation | variation of the exhaust temperature resulting from external temperature is reduced.
In addition to the outside air temperature, the control unit 301 may acquire disturbance element data and reflect it in the output of step S6. Further, the method of reflecting the disturbance element data is not limited to the example described here. For example, when outputting the display data described above, the control unit 301 may output display data for displaying a temporal change in the outside air temperature in addition to the scavenging pressure and the exhaust temperature.

As yet another output example, the control unit 301 may acquire fuel consumption data of the main engine 210 and reflect the fuel consumption in the output. For example, the control unit 301, when the scavenging pressure is decreased and the exhaust gas temperature is increased, when the fuel efficiency is equal to or lower than a predetermined value, the control unit 301 generates data for notifying that the fuel efficiency has decreased due to the supercharger 220. When the fuel consumption becomes a predetermined value or less during other periods, data for notifying that there is a cause other than the supercharger 220 is output.
The method of reflecting the fuel consumption data on the output in step S6 is not limited to the example described here. For example, when outputting the display data described above, the control unit 301 may output display data for displaying a change in fuel consumption over time in addition to the scavenging pressure and the exhaust temperature.

According to the embodiment described above, based on the data of the scavenging pressure and the exhaust gas temperature of the pressurized gas sent from the supercharger 220 to the main engine 210, even if the data to be referred to is less than in the past, The deterioration over time of the supercharger 220 can be accurately grasped.
The load on the main engine 210 changes depending on the operating state of the ship 1, and the scavenging pressure and the exhaust temperature can change due to the change in the load. Even in this case, since the computer apparatus 300 outputs changes over time in the scavenging pressure and the exhaust temperature for each load band, it becomes possible to more accurately grasp the aging deterioration of the supercharger 220. . Further, although the scavenging pressure and the exhaust temperature may change depending on the weather and sea conditions, the computer device 300 does not reflect the data at the time of the predetermined weather and sea conditions such as stormy weather in the output. It becomes possible to grasp deterioration more accurately.
