  On the other hand, a warning display unit 3 is arranged on the side of the water spray gun opening / closing display images 40, 40, 40, 40, 40, and the warning display unit 3 has a water absorption vacuum pressure of the main pump near the water absorption limit. The water shortage warning image 30 that lights up and warns when it becomes, the waterfall warning image 31 that lights up and warns when the water level in the suction pipe of the main pump falls below the dischargeable water level, and the vacuum pump operating time exceeds a predetermined time (for example, 60 seconds) The vacuum time warning image 32 that lights up and warns is displayed in the vertical direction at a distance in this order.

  In this way, when the pumps are in a predetermined state, the warning images 30, 31, 32 of the warning display unit 3 are lit and displayed to warn the operator that the pumps are in the predetermined state. Like to do.

  Further, in the middle area where the display portion 2a is divided into approximately three parts in the vertical direction, the needle image is formed at the center of the numerical display image in which numbers are added to the arc-shaped scales in the areas slightly on both sides from the center in the left-right direction. The first analog meter image A1 and the second analog meter image A2 are displayed. The first analog meter image A1 and the second analog meter image A2 are displayed. The sizes of the first and second analog meter images A1 and A2 are substantially the same, and are larger than the size of any of the images D1 to D46 described above.

  Thus, since the first and second analog meter images A1 and A2 are displayed in a large size in the middle area of the display unit 2a, the first and second analog meter images A1 and A2 are displayed even from a position relatively distant from the display unit 2a. The relative position of the needle image with respect to the numerical display images of the analog meter images A1 and A2 can be reliably recognized. Further, the relative position of the needle images of the first and second analog meter images A1 and A2, that is, the graphic recognition, can instantly determine whether or not the pump is operating normally. In such an urgent work as described above, the measurement data can be viewed instantly and easily without taking time to read the numbers.

  Here, in the basic screen displayed as the initial screen of the normal screen, as shown in FIG. 3, the image of the coupled meter is displayed on the first analog meter image A1, and the image of the pressure gauge is displayed on the second analog meter image A2. It is displayed. That is, in the first analog meter image A1, the water pressure on the water suction side of the main pump is displayed at the rotation position of the needle image, and in the second analog meter image A2, the water pressure on the water discharge side of the main pump is displayed on the needle image. Each is displayed in the moving position. The characters “couple meter” are displayed at the approximate center position of the first analog meter image A1, and the characters “pressure gauge” are displayed at the approximately center position of the second analog meter image A2. At the center of the bottom of the first and second analog meter images A1 and A2, a digital meter portion for displaying the value indicated by the needle image with a number is provided.

  As described above, the working efficiency is improved by preferentially displaying the coupled meter and the pressure gauge, which are generally visually recognized in the fire pump operation, as the initial screen. In addition, since the compound gauge and pressure gauge are displayed on the predetermined side, it is possible to prevent accidents in which both instrument images are mistaken for each other without checking the letters on the compound gauge and the pressure gauge. it can.

  It goes without saying that the pressure gauge image may be displayed on the first analog meter image A1, and the coupled meter image may be displayed on the second analog meter image A2.

  When the basic screen is displayed and the rotation button 12a or the flow rate button 12b of the operation unit 1 is operated, for example, as shown in FIG. 3 and FIG. Instead of the image of the growth meter, a tachometer image or a flow meter image is displayed. 3 shows a normal screen when the rotation button 12a is operated, and FIG. 4 shows a normal screen when the flow meter button 12b is operated.

  In this way, the display unit 2a can be made compact by selectively displaying images of a plurality of types of instruments on the first analog meter image A1 and the second analog meter image A2, and the display unit 2a It can be used more effectively.

  In addition to the first analog meter image A1, the second analog meter image A2 may display a tachometer image or a flow meter image instead of the pressure gauge image described above. The instrument image displayed in the first analog meter image A1 is displayed in the second analog meter image A2, and the instrument image corresponding to the operated rotation button 12a or flow rate button 12b is displayed in the first analog meter image A1. You may make it do. However, if the display position of the image of the compound gauge and the image of the pressure gauge is kept constant, it prevents the operator from misidentifying the image of the compound gauge and the image of the pressure gauge as an image of another instrument. be able to.

  By the way, when such a normal screen is displayed on the display unit 2a, when the handling button 11b shown in FIG. 2 is operated, the screen displayed on the display unit 2a is changed from the normal screen to the following. When the screen is switched to the first handling screen and the handling button 11b is further operated, the screen is switched to the following second handling screen.

  FIG. 5 is an explanatory diagram illustrating an example of the first handling screen, and FIG. 6 is an explanatory diagram illustrating an example of the second handling screen. The first handling screen mainly explains the meaning content of each image displayed on the normal screen, and the second handling screen mainly deals with the handling method when the warning image is displayed and the handling of the operation unit 1. it's shown. In both figures, parts corresponding to those shown in FIG. 2 are denoted by the same reference numerals and description thereof is omitted.

  That is, as shown in FIG. 5, each image obtained by removing the first analog meter image A1 and the second analog meter image A2 from the normal screen is displayed on the first handling screen. In the vicinity of each of the warning images 30, 31, and 32, a warning display explanation image 3A is displayed that explains in what state the light is displayed. 4, a pump state display image explanation image 4 </ b> A that explains the display contents of the pump state display image 4 in characters is displayed, and when the operation state display images 5, 5,. An operation state display image explanation image 5A explained in characters for each type of button is displayed. Further, the digital meter image D6 described above and the digital meter image D7 displaying the total operation time of the main pump are displayed at appropriate positions.

  Thus, by displaying the description of the image displayed on the normal screen and the display state on the display unit 2a, the operator can easily understand the meaning of the image displayed on the normal screen and the display state. It is easy to understand.

  In addition, as shown in FIG. 6, the second handling screen includes a warning display handling image 3B in which a handling method when each of the warning images 30, 31, and 32 described above is lit and displayed, and the screen described above. Screen switching button explanation image 11A in which the function of the switching button section 11 is displayed in characters, instrument selection button explanation image 12A in which the function of the instrument selection button section 12 described above is displayed in letters, digital meter images D6 and D7, and display thereof Digital meter explanation images 6A and 7A each displaying the contents in characters are displayed.

  As described above, various information such as a handling method (coping method) when each of the warning images 30, 31, and 32 is lit and displayed is displayed on the display unit 2 a, so that the operator The countermeasures against warnings can be easily executed.

  Next, a method for controlling the operation of the display 2 and the operation of the pump by such a control device will be described.

  7 to 12 are flowcharts showing the operation control procedure of the display 2 and / or the pump by the control unit of the control device A shown in FIG. A control program according to such a control procedure is stored in advance in the memory of the control unit.

  As shown in FIG. 7, when the control device A is activated, the control unit of the control device A displays the basic screen shown in FIG. 2 on the display device 2 (step S <b> 1), and then displays the display device 2. The operation and the operation of the pump are controlled (steps S2 and S5).

  In order to control the display operation of the display device 2, as shown in FIGS. 8 and 9, the control unit of the control device A waits until the operation button 10a is operated (step S21), and the operation button 10a is operated. If so, the operation state display image (actuation button image) 5 corresponding to the display 2a is turned on (step S22). When the vacuum pump is activated, the control unit causes the display 2a to turn on and display the vacuum pump operation display image 43. When the vacuum pump is stopped, the control unit causes the display 2a to turn off the vacuum pump operation display image 43 (step S1). S23). In addition, the control unit turns on and displays the vacuum time warning image 32 when, for example, 60 seconds have elapsed since the vacuum pump was activated (step S24).

The numerical value detected by the sensor is displayed on .about.40a (step S26). Further, the control unit calculates the rotation position of the needle images of the first and second analog meter images A1 and A2 based on the detection value given from the corresponding sensor (step S27), and calculates the calculated rotation position. The needle image is moved and displayed (step S28).

  The control unit determines whether or not the instrument selection button unit 12 has been operated (step S29), and if not, returns to step S25. On the other hand, when it is determined that the instrument selection button unit 12 has been operated, the control unit causes the display unit 2 to display the instrument corresponding to the first analog meter image A1 (step S30).

  Next, the control unit determines whether or not the above-described handling button 11b has been operated (step S31), and if not, returns to step S25. On the other hand, when determining that the handling button 11b has been operated, the control unit causes the display device 2 to display the first handling screen described above (step S32). The control unit determines whether or not the handling button 11b has been operated again (step S33). If the handling button 11b has not been operated, the control unit determines whether or not the normal button 11a has been operated (step S34). And a control part returns to step S32, when the normal button 11a is not operated.

  On the other hand, when it is determined in step S33 that the handling button 11b has been operated, the control unit causes the display 2 to display the above-described second handling screen instead of the first handling screen (step S35). The control unit further determines whether or not the handling button 11b is operated (step S36). If the handling button 11b is not operated, the control unit determines whether or not the normal button 11a is operated (step S37). When the normal button 11a is not operated, the control unit returns to step S35. On the other hand, when determining that the handling button 11b is further operated in step S36, the control unit returns to step S32 and displays the first handling screen again. Let

  On the other hand, when it is determined that the normal button 11a has been operated in steps S34 and S37 described above, the control unit causes the display device 2 to display the basic screen described above (step S38). Further, the control unit turns on the water shortage warning image 30 or the water fall warning image 31 when a water shortage or water fall signal is given from the sensor (step S39). Then, the control unit determines whether or not the emergency button 10c has been operated (step S40), and repeats the operations from step S25 to step S40 until it is determined that it has been operated.

  Next, the operation control procedure of the pump in step S5 will be described with reference to FIGS.

  As shown in FIG. 10, the control unit waits until the operation button 10a is operated (step S49). When the operation button 10a is operated, after controlling the operation of the vacuum pump (step S50), the main pump The operation control procedure of the pump by controlling the operation of (Step S60)

  When controlling the operation of the vacuum pump, as shown in FIG. 11, the control unit determines whether or not a water filling signal is given from a water filling sensor provided in the main pump (step S52), and the water filling signal is determined. Is not given, the vacuum pump is operated (step S53). The control unit determines whether or not the stop button 10b has been operated (step S54), and if it has not been operated, the vacuum pump is operated until it is determined in step S52 that a water filling signal has been given.

  On the other hand, when it is determined in step S54 that the stop button 10b has been operated, and when it is determined that the water filling signal is given in step S52, the control unit stops the operation of the vacuum pump (step S55).

  On the other hand, when controlling the operation of the main pump, as shown in FIG. 12, the control unit determines whether or not the emergency button 10c is operated after the operation of the vacuum pump is stopped (step S61). When the button 10c is not operated, the main pump is activated (step S62). The control unit determines whether or not the UP button 13a or the DOWN button 13b has been operated (step S63), and when it is operated, executes a control to open or close the throttle according to the operated button ( Step S64).

  When the UP button 13a or the DOWN button 13b is not operated, the control unit skips step S64 and returns to step S61. And a control part repeats operation from step S61 to step S64 until it judges that the emergency button 10c was operated by step S61, and when it judges that the emergency button 10c was operated, operation | movement of the main pump is stopped (step). S65).

  In this embodiment, the operation of the main pump is stopped by the emergency button 10c. However, the present invention is not limited to this, and the operation of the main pump may be stopped by the stop button 10b described above. .

  FIG. 13 is an explanatory diagram for explaining the configuration of the control device according to the second embodiment, in which numerical values used for control can be set using a screen. In the figure, parts corresponding to those shown in FIG.

  As shown in FIG. 13, the operation button unit 10 is provided with a hand button 10d for switching between automatic operation and manual operation instead of the emergency button 10c (see FIG. 2) described above. Here, in the automatic operation, the operation of the main pump is controlled by a preset value, and in the manual control, the operation of the main pump is controlled by a value set externally as described later. ing. The stop button 10b is configured to stop the operations of the vacuum pump and the main pump.

  When the operation state display image 5 corresponding to the hand button 10d is automatically displayed, when the hand button 10d is operated, the word "manual" is lit on the operation state display image 5. When the buttons to be controlled are operated from the rotation button 12a, the flow rate button 12b, the coupling button 12c, and the pressure button 12d described above, an image of the instrument is displayed in the second analog meter image A2, for example, and a numerical value is displayed. A set value mark image B2 having an appropriate shape is displayed in the vicinity of the display image. The position of the set value mark image B2 can be moved by the UP button 13a and the DOWN button 13b described above. The UP button 13a and the DOWN button 13b are operated to set the position as shown in FIG. The required first control numerical value is set by moving the value mark image B2 to the required numerical value position.

  Note that the type of control using the first control numerical value set in this way (for example, target value control or maximum value control) is predetermined.

  Thereby, for example, the set value mark image B2 on the second analog meter image A2 displayed on the display device 2 can be moved and the first control numerical value can be set by the graphic recognition, and therefore the first control numerical value can be easily set. And it can be set reliably.

  Then, when the manual control is selected as described above and the first control numerical value is set, the control unit of the control device A uses the first control numerical value to control the operation of the main pump to the target value control or Control by local maximum control.

  FIG. 14 is an explanatory diagram for explaining the configuration of the control device according to the third embodiment, in which sub-control can be performed in addition to the main control which is one control described above. In the figure, parts corresponding to those shown in FIG. 13 are denoted by the same reference numerals and description thereof is omitted.

  In the same way as before, the user operates the hand button 10d to perform manual control, and then operates the first control target button from the rotation button 12a, the flow rate button 12b, the coupling button 12c, and the pressure button 12d, and the UP button The first control numerical value is set by 13a and the DOWN button 13b. In FIG. 14, the pressure button 12d is operated, and the value related to the pressure gauge is set as the first control numerical value by the second analog meter image A2.

  Next, the second control target button is operated from buttons other than the buttons related to the first control numerical value, for example, the rotation button 12a, the flow rate button 12b, and the coupled button 12c. At this time, when the image of the instrument is not displayed on the display unit 2a, the image of the instrument is displayed in the first analog meter image A1 in the present embodiment. In the case shown in FIG. 14, the coupled button 12c is operated, and the coupled meter image is displayed in the first analog meter image A1.

  At this time, as before, the set value mark image B1 having an appropriate shape is displayed in the vicinity of the numerical display image of the first analog meter image A1. Then, the required second control numerical value is set by operating the UP button 13a and the DOWN button 13b to move the set value mark image B1 to the position of the required numerical value.

  Next, the operation of the control device A when such control numerical values are set will be described.

  FIG. 15 is a flowchart showing a control procedure of the operation of the main pump by the control device A when the control numerical value is set. The control unit of the control device A determines whether or not the stop button 10b has been operated (step S61a), and if it has not been operated, determines whether or not the manual mode has been selected by the own button 10d. (Step S62a). When the manual mode is not selected, the control unit determines that the automatic mode is selected, and executes automatic mode control for controlling the operation of the main pump so as to obtain a preset output (step S63a). .

  On the other hand, if the control unit determines that the manual mode is selected in step S62a, it determines whether or not the first control numerical value is set as described above (step S64a), and is set. If not, it waits until the first control numerical value is set.

  When the first control numerical value is set, the control unit determines whether or not the second control numerical value is set as described above (step S65a). Then, when the second control numerical value is not set, the control unit controls the operation of the main pump using the first control numerical value (step S66a). For example, when the first control numerical value is a pressure, target value control is performed to control the operation of the main pump so that the pressure becomes the first control numerical value.

  On the other hand, when the second control numerical value is set in step S64a, the control unit performs the positive control of the operation of the main pump using the first control numerical value (step S67a), in addition to the second control. Sub-control of the operation of the main pump using the numerical values is performed (step S68a). For example, as the main control, target value control for controlling the operation of the main pump so that the pressure becomes the first control value is performed, and as the sub-control, the main pump is set so that the flow rate becomes equal to or less than the second control value. The maximum value control is performed to control the operation.

  The control unit repeats the operations from step S61a to step S68a until it is determined that the stop button 10b is operated in step S61a. When the stop button 10b is operated, the operation of the main pump is stopped (step S69a). ).

  As described above, since the double control by the primary and secondary control is performed, the operation of the main pump can be performed more safely. Further, as before, the second control numerical value can be set by graphic recognition, and therefore the second control numerical value can be set easily and reliably.
