Summary of the Invention

[0004] Pump operators engaged in firefighting operations need to operate fire pumps (water pumps) while checking pressure, flow rate, and surrounding conditions. Therefore, it is desirable that the water pump flow rate and other information displayed on the fire pump control panel or a nearby monitor be easy to see and understand. However, the current monitor size is only about 7 inches, and various numerical values ​​are displayed on it, making it somewhat difficult to read. While increasing the monitor size to improve visibility could be considered, this is not practical due to space and cost considerations. Therefore, the present invention aims to provide a fire pump display unit that offers excellent visibility even if the monitor size is similar to that of the current system, and a fire pump control panel equipped with said fire pump display unit.

[0006] According to the present invention, it is possible to provide a fire pump display unit with excellent visibility even if the monitor size is about the same as the current one, and a fire pump control panel equipped with the fire pump display unit. [Brief explanation of the drawing]

[Figure 7]Reference diagram showing the monitor of the fire pump display unit (with maintenance notification superimposed). [Figure 8] Reference diagram showing the monitor of the fire pump display unit (with a notification indicating an abnormality superimposed on the main screen). [Modes for carrying out the invention]

[0008] The fire pump display according to the first embodiment of the present invention includes a monitor that displays information regarding the operating status of the fire pump. The monitor has a pressure / compound pressure display area that displays the discharge pressure and suction pressure of the fire pump. In the pressure / compound pressure display area, a pressure graph, which is a bar graph showing the discharge pressure, and a compound pressure graph, which is a bar graph showing the suction pressure, are displayed adjacent to each other. The scales of the pressure graph and the positive pressure scale of the compound pressure graph are provided integrally. According to this embodiment, by displaying the pressure graph and the compound pressure graph adjacent to each other and integrating the positive pressure scale, the display area of ​​the bar graph can be made more compact, reducing the proportion it occupies in the pressure / compound pressure display area. This allows for more space to be allocated for other numerical values, characters, etc., improving visibility. Furthermore, since the discharge side pressure and the suction side pressure can be viewed simultaneously by the two adjacent bar graphs, it becomes easier for pump operators to understand the operating status of the fire pump.

[0009] A second embodiment of the present invention is a fire pump indicator according to the first embodiment, wherein the integrally provided scale has uniform intervals from zero to the maximum value, and the scale unit is larger in the range from the predetermined value to the maximum value than in the range from zero to the predetermined value. According to this embodiment, the size of the pressure / compound pressure display area can be reduced by making the scale units coarser and shortening the length of the portion of the bar graph display area that is not often used in practice.

[0010] In the third embodiment of the present invention, in the display for a fire pump according to the first embodiment, the display area of the bar graph is shorter on the negative pressure side than on the positive pressure side. According to this embodiment, the size of the pressure / connected pressure display area can be made smaller than when the lengths of the display areas of the bar graph are the same on the positive pressure side and the negative pressure side.

[0011] In the fourth embodiment of the present invention, in the display for a fire pump according to the first embodiment, the positive pressure side of the display area of the bar graph has a curved shape. According to this embodiment, by making the display area of the bar graph on the positive pressure side have a curved shape, even if the scale intervals are substantially the same as in the case of a linear shape, the size of the pressure / connected pressure display area can be made smaller by suppressing the dimensions in the increasing and decreasing directions of the bar graph.

[0012] In the fifth embodiment of the present invention, in the display for a fire pump according to the fourth embodiment, in the pressure / connected pressure display area, the pressure value, which is the value of the discharge side pressure, is displayed on the positive pressure side of the zero position of the scale of the bar graph, and the connected pressure value, which is the value of the suction side pressure, is displayed on the negative pressure side of the zero position of the scale of the bar graph, and the display area of the pressure value is located on the inner peripheral side of the display area of the bar graph having a curved shape. According to this embodiment, since only the suction side pressure requires the display on the negative pressure side of the bar graph, by displaying the pressure value on the positive pressure side of the zero position of the scale of the bar graph and the connected pressure value on the negative pressure side, the pump operator can intuitively identify which of the two values is the pressure value and which is the connected pressure value, and the misidentification of the two values is prevented. Also, by making the display area of the pressure value be on the inner peripheral side of the display area of the bar graph having a curved shape, the size of the pressure / connected pressure display area can be made smaller than when it is located on the outer peripheral side.

[0013] A sixth embodiment of the present invention is a fire pump display according to the fifth embodiment, wherein the pressure graph is displayed adjacent to the inner circumference of the compound pressure graph, the numerical values ​​of the integrally provided scale are displayed adjacent to the inner circumference of the pressure graph, the negative pressure side of the bar graph display area is linear in shape, the numerical values ​​of the negative pressure side scale of the compound pressure graph are displayed adjacent to the compound pressure graph in the portion corresponding to the negative pressure side assuming that a negative pressure side exists in the pressure graph, and the display area for the compound pressure values ​​is located to the side of the numerical values ​​of the negative pressure side scale of the compound pressure graph. According to this embodiment, even without reducing the size of the compound pressure value, the compound pressure value, which also requires space for the "-" symbol, can be placed at an appropriate distance from the scale value, resulting in good visibility.

[0014] A seventh embodiment of the present invention is a fire pump indicator according to the fifth embodiment, wherein when the discharge pressure falls outside the normal range, the pressure value is displayed in a different color than when it is within the normal range, and when the suction pressure falls outside the normal range, the compound pressure value is displayed in a different color than when it is within the normal range. According to this embodiment, in the event of a water leak or low-pressure relay, the pump operator can be alerted by a change in the color of the numerical value.

[0015] An eighth embodiment of the present invention is a fire pump display device according to the first embodiment, wherein the display colors for the pressure graph and the compound pressure graph are different, the display area of ​​the pressure graph is colored with a transparent color of the same type as the display color of the pressure graph, and the display area of ​​the compound pressure graph is colored with a transparent color of the same type as the display color of the compound pressure graph. According to this embodiment, the pump operator can easily distinguish between the display area of ​​the pressure graph and the display area of ​​the compound pressure graph.

[0016] A ninth embodiment of the present invention is a fire pump indicator according to the eighth embodiment, wherein at least one of a first identification line indicating a pressure graph display area and a second identification line indicating a compound pressure graph display area is displayed along the longitudinal direction of the bar graph display area, the display color of the first identification line is the same color as the pressure graph, and the display color of the second identification line is the same color as the compound pressure graph, at least on the positive pressure side. According to this embodiment, it becomes even easier for pump operators to distinguish between the display area of ​​the pressure graph and the display area of ​​the compound pressure graph.

[0017] A tenth embodiment of the present invention is a fire pump indicator according to the ninth embodiment, wherein the display color of the second identification line is different from the display color of the compound pressure graph on the negative pressure side. According to this embodiment, the pump operator can easily determine whether the suction side pressure is positive or negative.

[0018] The fire pump control panel according to the 11th embodiment of the present invention comprises a fire pump indicator according to any one of the first to tenth embodiments and a fire pump control unit used for operating the fire pump. According to this embodiment, the pump operator can accurately grasp the operating status of the fire pump using a monitor with excellent visibility and operate the fire pump accordingly. [Examples]

[0019] The following describes a display unit for a fire pump and a fire pump control panel according to one embodiment of the present invention. Figure 1 shows a display unit for a fire pump, Figure 2 shows the monitor for the fire pump display unit, Figure 3 shows the pressure / compound pressure display area of ​​the monitor, Figure 4 shows the fire pump control panel, and Figure 5 is a left side view of a fire engine. As shown in Figure 5, the side of the fire pump truck 1 is equipped with a discharge port 2 connected to the discharge side of the fire pump (water pump) via a discharge pipe, etc., a water intake port 3 and a relay port 4 connected to the suction side of the fire pump via a water intake pipe, etc., and a fire pump control panel 5 used to operate the fire pump. Two discharge ports 2 are located on each of the left and right sides of the vehicle body, and fire hoses are connected to them. One fire pump control panel 5, one water intake port 3, and one relay port 4 are located on each of the left and right sides of the vehicle body. A water intake hose used to draw water from a water source, etc., is connected to the water intake port 3, and a relay hose used to connect to other fire trucks, etc., is connected to the relay port 4.

[0020] As shown in Figure 4, the fire pump control panel 5 is equipped with a fire pump indicator 6 that displays information regarding the operating status of the fire pump, a pressure gauge 7 that shows the pressure in the discharge pipe of the fire pump, a compound gauge 8 that shows the pressure in the suction pipe of the fire pump, and a fire pump control unit 9 used to operate the fire pump. The fire pump control unit 9 has a throttle handle 91 used to adjust the engine speed, a vacuum pump operation switch 92, a vacuum pump stop switch 93, and a PTO operation switch 94. The pressure gauge 7 and compound gauge 8 are located to the side of the fire pump indicator 6 and arranged vertically, while the throttle handle 91, vacuum pump operation switch 92, vacuum pump stop switch 93, and PTO operation switch 94 are located below the fire pump indicator 6 and arranged horizontally.

[0021] The fire pump display unit 6 has a monitor 61 which is a liquid crystal color monitor and a screen operation switch 62 used for screen operation. The screen operation switches 62 are physical buttons located around the monitor 61, and correspond to the button name tabs 61Af displayed on the monitor 61 (see Figure 1). For example, when the button name tab 61Af labeled "MENU" is displayed in the upper left corner of the monitor 61, pressing the top left screen operation switch 62 corresponding to this tab will switch to the MENU screen. While the monitor 61 can be operated using a touch panel, it is preferable to use physical buttons so that the screen can be operated without removing gloves, as pump operators often wear gloves.

[0022] The main screen of monitor 61 (the screen primarily used during firefighting operations) has a pressure / compound pressure display area 61A, a throttle / rpm display area 61B, and a flow rate / pump status display area 61C. During firefighting operations, the pressure / compound pressure display area 61A constantly displays the discharge and suction pressure of the fire pump, the throttle / rpm display area 61B constantly displays the engine throttle level and pump speed, and the flow rate / pump status display area 61C constantly displays the flow rate at each discharge port 2, the usage status of each relay port 4 and suction port 3, and the remaining level of the firefighting water tank in which the water supplied to the fire pump is stored. Since the main screen of monitor 61 constantly displays not only the discharge flow rate but also the discharge and suction pressures, the pump operator can grasp the discharge and suction pressures on monitor 61 without shifting their gaze to the pressure gauge 7 or compound gauge 8. Furthermore, since the discharge flow rate and pump rotation speed are also displayed on the same screen, it becomes easier to check these values ​​together.

[0023] However, as mentioned above, the size of the monitor 61 is often around 7 inches, so if the discharge pressure and suction pressure are to be displayed at all times in addition to the discharge flow rate and pump rotation speed, the display of each value will become small and visibility will decrease, which may make it difficult for the pump operator to grasp the relationship between the discharge pressure and suction pressure. Therefore, in this embodiment, in the pressure / compound pressure display area 61A which displays the discharge side pressure and the intake side pressure, a pressure graph 61Aa, which is a bar graph showing the discharge side pressure, and a compound pressure graph 61Ab, which is a bar graph showing the intake side pressure, are displayed adjacent to each other, and the scale of the pressure graph 61Aa and the positive pressure scale of the compound pressure graph 61Ab are provided as a single unit. This makes the bar graph display area more compact, reducing its proportion of the pressure / compound pressure display area 61A, thereby freeing up space for other numerical values ​​and text, improving visibility. Furthermore, pump operators can simultaneously view the discharge and suction pressures on two adjacent bar graphs, making it easier to understand the operating status of the fire pump. Pump operators can also more easily grasp the relationship between the two values, such as how the discharge pressure compares to the suction pressure. Additionally, the bar graph display of discharge and suction pressures allows pump operators to quickly grasp the approximate values ​​of the discharge and suction pressures, making it easier to notice abnormalities in the fire pump.

[0024] In the integrated scale 61Ae (hereinafter referred to as the "common scale") on the positive pressure side of the pressure graph 61Aa and the compound pressure graph 61Ab, the interval between divisions is approximately uniform from zero to the maximum value, and it is preferable that the range from the predetermined value to the maximum value is larger than the range from zero to the predetermined value. The range from zero to the predetermined value is considered to be the range of actual fluctuations in firefighting activities. For example, in this embodiment, the common scale 61Ae has approximately equal intervals between divisions, but the division units are 0 MPa, 0.5 MPa, 1 MPa, 1.5 MPa, and 3.5 MPa. In the range from zero to a predetermined value (0 to 1.5 MPa), the increments are 0.5 MPa, while after 1.5 MPa, the next value is the maximum value of 3.5 MPa. The predetermined value is set to 1.5 MPa because, although the range of the pressure gauge 7 is 0 to 3.5 MPa and the positive pressure range of the compound gauge 8 is 0 to 2 MPa, in firefighting activities, both typically fall within the range of 0 to 1.5 MPa. In this way, the size of the pressure / compound pressure display area 61A can be reduced by making the scale units coarser and shortening the length of the parts of the bar graph display area that are not often used.

[0025] In the pressure / compound pressure display area 61A, the discharge and suction pressures of the fire pump are displayed not only as bar graphs but also as numerical values. While the analog bar graph scale has increments of 0.5 MPa on the positive pressure side and 0.025 MPa on the negative pressure side, the pressure value 61Ac, which is the discharge pressure value, and the compound pressure value 61Ad, which is the suction pressure value, change in increments of 0.01 MPa. This allows pump operators to easily determine the precise values ​​of discharge and suction pressures as needed.

[0026] As shown in Figure 4, the compound gauge 8 has fewer divisions on the negative pressure side than on the positive pressure side, but the interval between divisions is larger on the negative pressure side than on the positive pressure side. As a result, the range of motion of the needle 8A is the same on both the positive and negative pressure sides. In contrast, as shown in Figure 3, the bar graph display area in the pressure / compound pressure display area 61A is made shorter on the negative pressure side than on the positive pressure side by making the scale interval on the negative pressure side smaller than the scale interval on the positive pressure side. This makes it possible to reduce the size of the pressure / compound pressure display area 61A compared to when the length of the bar graph display area is the same on both the positive and negative pressure sides.

[0027] The bar graph's display area is continuous vertically, with positive and negative pressure sides. The pressure value 61Ac is displayed above the zero position on the bar graph scale (positive pressure side), while the compound pressure value 61Ad is displayed below the zero position on the bar graph scale (negative pressure side). Since the negative pressure display on the bar graph is only necessary for the suction side pressure (compound pressure), this arrangement allows pump operators to intuitively understand that the upper value is the discharge side pressure and the lower value is the suction side pressure, preventing them from confusing the two values.

[0028] The display area for the negative pressure bar graph located at the bottom is linear, while the display area for the positive pressure bar graph located at the top is a gently curving shape at a 90-degree angle. In addition, the pressure value 61Ac and the compound pressure value 61Ad are displayed inside the bar graph. As a result, within the vertically elongated rectangular pressure / compound pressure display area 61A, the portion where the bar graph and the pressure value 61Ac and compound pressure value 61Ad are displayed is a sector with a central angle of 90 degrees on the upper side, with two 1 / 4 ring-shaped bar graph display areas on its outer circumference, separated by the zero position of the bar graph, and a horizontally elongated rectangle on the lower side, with the negative pressure display area of ​​the compound pressure graph 61Ab on one side. By making the display area of ​​the bar graph on the positive pressure side, which is longer than the negative pressure side, a curved shape, the size of the pressure / compound pressure display area 61A can be reduced by suppressing the dimension in the direction of increase or decrease of the bar graph, even if the scale interval is approximately the same as when the positive pressure side is also a straight shape. Furthermore, by positioning the pressure value 61Ac's display area on the inner circumference of the curved bar graph's display area, the size of the pressure / compound pressure display area 61A can be reduced compared to positioning it on the outer circumference.

[0029] In the display area of ​​the positive pressure bar graph, which has a curved shape, the pressure graph 61Aa is displayed adjacent to the inner circumference of the compound pressure graph 61Ab, and the value of the common scale 61Ae is displayed adjacent to the inner circumference of the pressure graph 61Aa. Furthermore, in the display area of ​​the bar graph on the negative pressure side, which has a linear shape, there is no need to display the pressure graph 61Aa. Therefore, the numerical values ​​on the negative pressure side scale of the compound pressure graph 61Ab are displayed adjacent to the compound pressure graph 61Ab in the portion corresponding to the negative pressure side display area, assuming that a negative pressure side exists in the pressure graph 61Aa. In other words, the numerical values ​​on the scale of the pressure graph 61Aa are displayed next to the negative pressure side display area of ​​the compound pressure graph 61Ab, rather than the display area of ​​the pressure graph 61Aa. Additionally, pressure values ​​61Ac are displayed inside the values ​​of the common scale 61Ae, and compound pressure values ​​61Ad are displayed inside the values ​​of the negative pressure scale on the compound pressure graph 61Ab. The compound pressure value 61Ad, which can sometimes be a negative value, requires space to display a "-" symbol before the value. However, as in this embodiment, the pressure value 61Ac is displayed above the zero position of the bar graph scale, and the compound pressure value 61Ad is displayed below it. The compound pressure graph 61Ab is located on the outer edge of the pressure graph 61Aa, the negative pressure side of the compound pressure graph 61Ab is linear, and the scale value is displayed in the portion corresponding to the negative pressure side. This allows for an appropriate distance between the scale value and the compound pressure value 61Ad without reducing the size of the compound pressure value 61Ad, resulting in good visibility. It is preferable that the display size of the pressure value 61Ac and the display size of the compound pressure value 61Ad are the same. Furthermore, by displaying the scale values ​​on the inner circumference side of the bar graph, the size of the pressure / compound pressure display area 61A can be reduced compared to when they are displayed on the outer circumference side.

[0030] Although the discharge and suction pressures of the fire pump are constantly displayed on the monitor 61, making it possible to omit the displays from the pressure gauge 7 and compound gauge 8, there is a time lag between starting the fire pump control panel 5 and the discharge and suction pressures being displayed on the monitor 61. Therefore, it is preferable to also display the pressures from the pressure gauge 7 and compound gauge 8.

[0031] In the pressure / compound pressure display area 61A, a pressure label 61Ag labeled "■Pressure" is displayed above the pressure value 61Ac, and a compound pressure label 61Ah labeled "□Compound" is displayed above the compound pressure value 61Ad. This allows pump operators to quickly identify which of the two values ​​represents pressure and which represents compound pressure. Furthermore, the display colors for the pressure graph 61Aa and the compound pressure graph 61Ab are different; for example, the pressure graph 61Aa is blue and the compound pressure graph 61Ab is gray. Also, the "■" in the pressure label 61Ag is displayed in the same color family as the display color of the pressure graph 61Aa (e.g., blue), and the "□" in the compound pressure label 61Ah is displayed in the same color family as the display color of the compound pressure graph 61Ab (e.g., gray). In addition, the background of the display area of ​​the bar graph is a transparent color of the same color family as the display color of each bar graph; for example, the display area of ​​the pressure graph 61Aa is semi-transparent gray and the display area of ​​the compound pressure graph 61Ab is semi-transparent blue. This allows pump operators to easily distinguish between the display areas of the pressure graph 61Aa and the compound pressure graph 61Ab.

[0032] Furthermore, at least one of the first identification line 61Ai, which indicates the display area of ​​the pressure graph 61Aa, and the second identification line 61Aj, which indicates the display area of ​​the compound pressure graph 61Ab, is displayed along the longitudinal end of the bar graph's display area. The display color of the first identification line 61Ai is the same color as the display color of the pressure graph 61Aa (e.g., blue), and the display color of the second identification line 61Aj is the same color as the display color of the compound pressure graph 61Ab on the positive pressure side (e.g., gray). This makes it even easier for pump operators to distinguish between the display areas of the pressure graph 61Aa and the display areas of the compound pressure graph 61Ab. Furthermore, the display color on the negative pressure side of the second identification line 61Aj is different from the display color of the compound pressure graph 61Ab (e.g., gray), for example, red. This allows the pump operator to easily determine whether the suction side pressure is positive or negative.

[0033] The fire pump control panel 5 determines whether the discharge pressure or suction pressure of the fire pump is within the normal range. If it determines that the discharge pressure or suction pressure is outside the normal range, it changes the pressure value 61Ac or compound pressure value 61Ad in the pressure / compound pressure display area 61A displayed on the monitor 61 to a different color than when it is within the normal range. For example, when no abnormalities are detected, the pressure value 61Ac and the compound pressure value 61Ad are displayed in white. On the other hand, if the pressure in the discharge pipe exceeds the safety pressure, if the pressure in the discharge pipe exceeds the pressure resistance of the fire hose, or if phenomena such as cavitation or air leaks due to air mixing into the suction pipe are detected, the pressure value 61Ac will be displayed in yellow. In addition, if the relay water volume is insufficient, or if the relay pressure is too high to adjust to the specified pressure when using the automatic pressure adjustment function, the compound pressure value 61Ad will be displayed in yellow. This allows for the pump operator to be alerted by a change in the color of the numerical value in the event of an abnormality such as a water leak or low-pressure relay.

[0034] Below the pressure / compound pressure display area 61A, a throttle / rpm display area 61B is provided. The throttle / rpm display area 61B displays a throttle graph 61Ba, which shows the throttle level of the engine speed as a bar graph, and a rpm value 61Bb, which shows the rotation speed of the fire pump as a number. By displaying the throttle level and pump rotation speed, which have a certain degree of correlation, in close proximity, pump operators can more easily assess the operating status of the fire pump.

[0035] Monitor 61 uses a black background, and displays bar graphs, numbers, and text in red, light blue, green, white, yellow, and gray, utilizing contrast to emphasize various types of information. Furthermore, in order to make numerical values ​​and text easier to read by displaying them in a larger size, measures have been taken such as making the pressure / compound pressure display area 61A more compact, as mentioned above, and the information displayed has been limited to the bare minimum necessary.

[0036] Multiple button name tabs 61Af are displayed vertically at both the left and right ends of the monitor 61. Preferably, at least one end of the button name tabs 61Af is not displayed in whole or in part at all times, and its display area is kept small until a predetermined screen operation switch 62 is pressed. This allows other display areas, such as the pressure / compound pressure display area 61A and the throttle / rpm display area 61B, to be enlarged when not in use, making it easier to read numbers and characters. For example, as shown in Figure 2, on the main screen where flow rate, pressure, compound pressure, and pump rotation speed are displayed, the leftmost button name tab 61Af (MENU, CAFS, tank suction, alarm cancellation) is always fully displayed, but only the left border of the rightmost button name tab 61Af is always displayed, with the text hidden. When any of the screen operation switches 62 on the right are pressed twice in quick succession, as shown in Figure 6, the entire rightmost button name tab 61Af (symbol (oil change date setting screen call), upper pressure limit, automatic pressure adjustment, throttle lock) is displayed. At this time, the display size of the pressure / compound pressure display area 61A becomes smaller, but the 1.5~3.5MPa range of the pressure graph 61Aa and compound pressure graph 61Ab, which is not usually used, is hidden by the button name tab 61Af, so that the display of the 0~1.5MPa range and numerical values ​​does not become too small. When the entire button name tab 61Af on the far right is displayed, the display size of the throttle / rpm display area 61B also decreases, but the display size of the flow rate / pump status display area 61C remains unchanged.

[0037] The fire pump control panel 5 also has the following functions: 1. Calendar and clock display function This function displays the date and current time on the monitor 61. The fire pump control panel 5 is configured to receive GPS satellite signals and automatically correct the date and time, allowing the pump operator to confirm the accurate date and time. 2. Vehicle information display function This function displays the vehicle's remaining fuel level, DPR (diesel particulate filter) deposit amount, and engine coolant temperature on the monitor 61. This allows the pump operator to check the fuel level and other information on the monitor 61 without having to go to the driver's seat, thus reducing the burden during water discharge operations, which often last for long periods. 3. Voice guidance function This function issues warnings not only visually but also audibly in the event of a malfunction in the vehicle, fire pump, etc. For example, an audible warning will be issued if the pump runs dry for a predetermined period of time, if the pressure of the fire pump exceeds the pressure resistance setting of the fire hose, if the engine speed exceeds a predetermined value, or if the amount of DPR (diesel particulate filter) exceeds a predetermined value. 4. Maintenance notification function This feature displays a maintenance notification on the main screen as the vehicle's maintenance period approaches, as shown in Figure 7. Specific details regarding the maintenance schedule, such as the timing and content, can be found on a dedicated website, for example. This makes it easier for engine operators, who are the practitioners responsible for maintenance, to understand when maintenance is due. In addition, by using superimposed displays, there is no need to reserve a dedicated display area on the monitor 61 for guidance notifications, and this allows other display areas, such as the pressure / compound pressure display area 61A and the throttle / rpm display area 61B, to be made larger. 5. Electrical component abnormality detection function This function, when it detects an abnormality in electrical components such as an overcurrent, overlays a notification (abnormality alarm) on the main screen, as shown in Figure 8. The specific location and details of the abnormality can be viewed on a separate screen, for example, by switching the screen of monitor 61. This allows for early notification of abnormalities to the pump operator. Furthermore, by using superimposed displays, there is no need to reserve a dedicated display area on the monitor 61 for abnormality alarms, which allows for larger displays in other areas such as the pressure / compound pressure display area 61A and the throttle / rpm display area 61B.
