Description

  The present invention relates to a pump control unit and a pump device.

  Conventionally, as a pump device for supplying water to a building, a cabinet-type pump device that can be installed outdoors has been known. In a cabinet-type pump device, a pump and a pump control unit that controls the pump are housed in a cabinet and protected from rain and wind. The cabinet is required to have durability and robustness so as to protect the pump and the pump control unit, and is formed in a box shape from, for example, a metal steel plate (for example, see Patent Document 1).

  The cabinet generally comprises a cabinet body and a removable cover for assembly and maintenance of the pump and the pump control unit. In this case, for safety, the cover is attached and detached by a technician such as a maintenance worker, and the cabinet is designed with, for example, a key so that the cover is not attached or detached. In such a cabinet, the cover is arranged with some clearance therefrom so as not to interfere with the pump and the pump control unit in the cabinet. In particular, when the pump control unit in the cabinet is provided with an operation unit having a projection such as a toggle switch and a push switch, the operation panel is provided on the operation panel so that the switches are not erroneously operated due to opening / closing of the cover or impact on the cabinet. On the other hand, the cover is arranged with a relatively large gap.

  Conventionally, a pump device having a wireless communication function has been known (for example, see Patent Document 2). In this pump device, various command signals for operating the pump are received from the external device by wireless communication, and signals related to the operating state of the pump are transmitted to the external device. Since the information wirelessly communicated in this way is information handled by the main board that controls the pump, the electronic circuit for the wireless communication function is generally provided on the same board as the main board.

  The description is returned to FIGS. As shown in the drawing, two vertical pumps 12a and 12b are arranged in the cabinet 10 in parallel along the vertical direction. The vertical pumps 12a and 12b are, for example, booster pumps each having a pump unit 14 and a motor unit 16. In each of the vertical pumps 12a and 12b, the pump unit 14 is driven by power from the motor unit 16.

  A suction header 18 extending in the horizontal direction is connected to the suction sides of the vertical pumps 12a and 12b. The suction header 18 is connected to a suction pipe 22 having a ball valve 20 with a strainer via a pressure-reducing backflow preventer 24. A pressure sensor 26 that detects the pressure on the suction side is attached to the suction pipe 22. By connecting the water main to the strainer portion of the ball valve 20 with the strainer and operating the vertical pumps 12a and 12b with the ball valve 20 open, the tap water is supplied to the suction pipe 22 and the depressurized reverse flow. The air is sucked into each of the vertical pumps 12a and 12b via the preventer 24 and the suction header 18.

  On the other hand, a discharge elbow pipe 28 is connected to the discharge sides of the vertical pumps 12a and 12b. A discharge collecting pipe 34 for collecting (merging) water discharged from the vertical pumps 12a and 12b is connected to the discharge elbow pipe 28 via a discharge-side check valve 30 for preventing a reverse flow of the discharged water. ing. The discharge collecting pipe 34 has a flow switch 32 that detects a small amount of water and sends a signal (see FIG. 3). The discharge collecting pipe 34 is connected to an upper end of a bypass header 38 having a pressure sensor 36 for detecting a pressure on the discharge side. The bypass header 38 is connected to a pressure tank 40 at a predetermined position via a pressure tank pipe 42, and is connected at a lower end to a discharge pipe 46 having a ball valve 44.

  As a result, water discharged from the vertical pumps 12a, 12b along with the operation of the vertical pumps 12a, 12b passes through the discharge elbow pipe 28, the discharge-side check valve 30, the discharge collecting pipe 34, and the bypass header 38. Thus, the liquid is discharged from the discharge pipe 46 to the outside. When the pressure of the water in the suction header 18 is sufficiently high, the water in the suction header 18 is directly guided to the discharge pipe 46 via a built-in check valve (not shown) and is directed to the outside. Discharged. The pressure tank 40 acts to accumulate the pressurized water discharged from the vertical pumps 12a, 12b, thereby preventing the vertical pumps 12a, 12b from being frequently started and stopped, and acts to keep the supply water pressure smooth and constant.

  An inverter device 54 is provided above the vertical pumps 12a and 12b. The inverter device 54 drives each motor unit 16 at a variable speed by supplying alternating-current power to each motor unit 16 of the vertical pumps 12a and 12b with changing frequency and voltage. The inverter device 54 is housed in an inverter case 56 supported by the cabinet 10. The inverter case 56 has a heat sink 52 made of, for example, aluminum and having a radiating fin 50, and the inverter device 54 is placed and stored on the upper surface of the heat sink 52.

Unit) 70 is provided. The control unit 70 is disposed vertically above the connection port of the suction pipe 22 and the connection port of the discharge pipe 46. Further, the liquid flow paths of the vertical pumps 12a and 12b may be arranged vertically above the most vertically upper part. Thereby, the control unit 70 is flooded when the water supply device 1 is installed (when the water main pipe and the suction pipe 22 are connected, and when the water supply pipe to a water supply target such as a building and the discharge pipe 46 are connected) and the like. Can be suppressed. In the present embodiment, the control unit 70 is housed in the cabinet 10 separately from the inverter case 56 that houses the inverter device 54. Thus, maintenance and replacement of the inverter device 54 and the control unit 70 can be easily performed.

  FIG. 6 is a diagram illustrating the control unit of the present embodiment. The control unit 70 has a unit case 72 supported by the cabinet 10 and housing various components of the control unit 70. The unit case 72 accommodates, for example, a main board 73 for controlling the operation of the vertical pumps 12a and 12b to prevent the main board 73 from being wet. An operation panel 76 is provided on the front surface of the unit case 72. The operation panel 76 is fixed to the unit case 72 with screws or the like.

As shown in the figure, the operation panel 76 displays the operation state of the water supply device 1 (for example, the discharge pressure, the inflow pressure, the frequency (the number of rotations) of the vertical pumps 12a and 12b, and the current acting on the motor unit 16). , The operation / failure lamps 762 of the vertical pumps 12a and 12b, the display lamp 763 of the energy saving mode, the display lamp 764 of the operation state of the vertical pumps 12a and 12b, the abnormality display lamp 765, and the power supply It has a display lamp 766 and the like, and displays information about the water supply device 1. The operation panel 76 includes an E button 767 for selecting an energy saving mode, a selection button 768 for selecting an operation state of the vertical pumps 12a and 12b, a switching button 769 for switching the display of the display unit 761, It has a setting button 770 for setting various information of the device 1 and a run / stop switch 771 for selecting automatic operation / stop or manual operation / stop, and enables various operations of the water supply device 1. Note that, as described above, the control unit 70 including the operation panel 76 is housed inside the cabinet 10. When the cover 102 is closed, the user can visually recognize the operation panel 76 through the plate portion 104 of the cover 102, but cannot operate the operation panel 76.

  The operation panel 76 is provided with a communication unit 790 for wireless communication. With such a communication unit 790, the user can receive information from the water supply device 1 to the external device or transmit a command from the external device to the water supply device 1. The communication unit 790 communicates with an external device (external display) using, for example, near field communication (NFC: Near Field Communication) technology. The communication unit 790 is configured to be able to communicate with an external device even when the cover 102 of the cabinet 10 is closed. However, the communication unit 790 can use any type of wireless communication such as Bluetooth (registered trademark) and Wi-Fi in addition to NFC. However, NFC is advantageous in that communication can be completed only by bringing the communication unit 790 close to the external device. The communication unit 790 may be provided with an external connection terminal such as a USB (Universal Serial Bus) in addition to wireless communication, and may be configured to perform wired communication when the cover 102 of the cabinet 10 is opened. Good.

As shown in FIGS. 5, 7, and 8, the operation panel 76 includes a panel plate 77 made of resin or the like, an operation / display board 78, and a wireless communication board 79. The panel plate 77 has a first support surface 77a that supports the operation / display board 78 and a second support surface 77b that supports the wireless communication board 79, and functions as a panel surface of the operation panel 76. The operation / display board 78 is a circuit board for operating / displaying the operation panel 76, and is attached to and supported by the back surface of the first support surface 77 a of the panel plate 77. The wireless communication board 79 is a circuit board for the communication unit 790, and is attached to and supported by the rear surface of the second support surface 77b of the panel plate 77. In the present embodiment, the panel plate 77 has a first support surface 77a for supporting the operation / display board 78 formed vertically above and a second support surface 77b for supporting the wireless communication board 79 formed vertically below. However, the first support surface 77a may be formed vertically below and the second support surface 77b may be formed vertically above, or may be formed side by side in the horizontal direction. In the present embodiment, the operation / display board 78 and the wireless communication board 79 are separate circuit boards, and are respectively supported by the panel board 77. The operation / display board 78 and the wireless communication board 79 are electrically connected to a main board 73 for controlling the operation of the vertical pumps 12a and 12b, respectively, via wiring. However, the present invention is not limited to such an example, and the operation / display board 78 and the wireless communication board 79 are electrically connected to each other via wiring, and are mainly connected via one of the operation / display board 78 and the wireless communication board 79. It may be electrically connected to the board 73. Further, the control unit 70 is not limited to the one having each of the main board 73, the operation / display board 78, and the wireless communication board 79, and the operation / display board 78 or the wireless communication board 79 is integral with the main board 73. You may.

On the other hand, the wireless communication board 79 is configured to be fixed to the back surface of the second support surface 77b by a claw 77c provided on the back surface of the second support surface 77b. The claw portion 77c is formed integrally with the first support surface 77a and the secondary paper surface 77b by injection molding of a resin. As described above, since the wireless communication board 79 is fixed to the panel plate 77 by the claw portions 77c formed of resin instead of being fixed with metal screws or the like, the metal is arranged beside the wireless communication board 79. This can prevent the wireless communication function from being hindered. The fixing of the wireless communication board 79 to the panel plate 77 is not limited to the example shown in FIG. 8, but it is preferable that the wireless communication board 79 be detachably fixed by resin without using a metal fixing tool. For example, it is preferable that the wireless communication board 79 be fixed to the panel board 77 by a resin screw. Further, the operation / display board 78 is not limited to the one fixed by using the metal screw, but may be detachably fixed by resin.

  Here, as described above, the operation panel 76 of the present embodiment is provided with various buttons for various operations, a run / stop switch 771, and the like. These buttons and the run / stop switch 771 are arranged at a certain distance from the cabinet 10 so that unintended operation is not performed by opening / closing the cover 102 of the cabinet 10 or external impact on the cabinet 10. Is preferably performed. In particular, when a toggle switch or a lever switch of the operation panel 76 is included, it is difficult to judge invalidity of an erroneous operation by software such as a program like a push switch and forcibly change the state of the switch. For this reason, in the present embodiment, when the cover 102 is closed, the distance L1 between the operation / display board 78 of the operation panel 76 and the plate portion 104 of the cover 102 is provided with a relatively large margin (for example, A few centimeters). This also prevents the protruding portion (such as the sealing portion 109) of the plate portion 104 from physically interfering with the control unit 70 (operation panel 76).

  Further, a breaker (not shown) for each pump is housed in the control unit 70, and a breaker switch is arranged so that the breaker can be operated on the same operation surface as the operation panel 76. There is. If the switch of the breaker is accidentally turned off, the power supply of the inverter which is the driving source of the pump is turned off, and the pump cannot supply water. In order to prevent the breaker from being operated erroneously when the cover 102 is opened and closed, the distance L1 between the cover 102 and the plate portion 104 needs to be provided with a relatively large margin.

On the other hand, as shown in FIG. 5, the wireless communication board 79 is disposed so as to be located in front of the device as compared with the operation / display board 78. That is, the wireless communication board 79 is arranged so that the distance L2 between the plate portion 104 of the cabinet 10 and the distance L1 between the operation / display board 78 and the plate portion 104 is smaller (L2 <L1). As an example, in the present embodiment, the distance L2 between the wireless communication board 79 and the plate unit 104 is several mm (mm).
It is. In the present embodiment, the panel plate 77 of the operation panel 76 is formed such that the communication unit 790 is closer to the plate unit 104 of the cabinet 10 than the display unit 761 and the like. That is, the panel board 77 has a step 77c between the first support surface 77a that supports the operation / display board 78 and the second support surface 77b that supports the wireless communication board 79. The communication section 790 (panel board 77 and wireless communication board 79) of the operation panel 76 is provided so as to be parallel to the plate section 104 when the cover 102 is closed. Generally, when the communication unit 790 uses the NFC technology, in order to secure wireless communication in the communication unit 790, it is possible to bring an external device close to the wireless communication board 79 close to 10 cm (centimeter) or less. preferable. In the present embodiment, since the wireless communication board 79 is disposed near the plate unit 104 of the cabinet 10, when the user holds an external device over the communication unit 790 via the plate unit 104, the communication unit 790 Wireless communication with an external device can be performed better.

  FIG. 9 is a diagram illustrating an example of a control unit and an external device. FIG. 9 shows the control unit 70 in a functional block diagram. As shown, the control unit 70 includes a storage unit 701 for storing data, a calculation unit 702 for calculating data, and an I / O unit 703 for exchanging data with the pressure sensors 26 and 36, the inverter device 54, and the like. It has the function of Further, it has a function as a setting unit 704 for data setting, a display unit 705 for data display, and a communication unit 790 for wireless communication with the outside. The setting unit 704, the display unit 705, and the communication unit 790 are included in the operation panel 76 described above. Note that the setting unit 704 shown in FIG. 9 is provided with a reset button 780 and a clear button 781, unlike FIG. By pressing the clear button 781, the control unit 70 clears the display on the operation panel 76. In addition, when the reset button 780 is pressed, the control unit 70 issues abnormality information (for example, abnormality information of the vertical pumps 12a and 12b), maintenance information (for example, operation time, number of starts, usage period of consumable parts, failure history) and the like. Reset the data of.

  As the external device 170, for example, a general-purpose terminal device such as a smartphone, a mobile phone, a personal computer, and a tablet, or a dedicated terminal device such as a remote monitor is employed. As the display unit 705, a simple display such as a 7-segment LED and an indicator light can be employed. Further, as the external device 170, a high-performance display device with a liquid crystal screen using a touch input method or a press button method can be employed. In this case, simple information can be displayed on the display unit 705, and a large amount of information can be displayed on the external device 170. With such a configuration, by displaying information (for example, target pressure, current pressure, and the like) related to control of the vertical pumps 12a and 12b by the control unit 70 on the external device 170, a user unfamiliar with the water supply device can be misunderstood. In addition, the state of the water supply device 1 can be recognized.

  For example, in the conventional water supply device 1, the display unit 705 of the operation panel 76 displays the discharge pressure of the vertical pumps 12a and 12b during normal operation, and according to the operation of the operation panel 76, the rotation speed of each pump, It was configured to display current, power, and the like. The rotation speed and the like of each pump are only checked by a maintenance person at the time of periodic inspection or when a failure occurs. However, in the water supply device 1 of the present embodiment, for example, the power consumption of the water supply device 1 is determined by using the external device 170. Can be confirmed on a daily basis (eg, several times a day, several times a week, every few hours, etc.) by making a trend graph or the like. For this reason, the water supply device 1 can be managed using the external device 170 without opening the cover 102, and the opening and closing of the cover 102 and the mechanical operation of the operation panel 76 are reduced to prevent the damage or deterioration thereof. Can be suppressed.

On the operation panel 76 of the water supply device 1, when a plurality of failures occur at the same time, each failure information is switched and displayed at regular intervals, and it is difficult for the user to grasp all the failures. was there. On the other hand, in the water supply device 1 of the present embodiment, since a large amount of information can be displayed on the external device 170, it is possible to accurately inform the user of the failure information.

  Further, the water supply device 1 may be installed in an environment with much electrical noise such as a machine room or a pump room. In preparation for such a case, a display unit including a 7-segment LED, an indicator light, a mechanical push button, or the like that is more resistant to electrical noise than a liquid crystal display or a touch panel may be used as the display unit 705. Thereby, even if an abnormality occurs in the liquid crystal display or touch panel operation of the external device 170 due to the electric noise generated from the external environment, the display unit 705 can display and operate the minimum limit required for the operation of the water supply device 1. It can be carried out. Therefore, the water supply device 1 can be installed even in an environment with much electrical noise.

  Furthermore, when a general-purpose terminal device such as a smartphone, a mobile phone, a personal computer, or a tablet is adopted as the external device 170, dedicated application software for acting as the external device 170 is installed on these devices. You may. In this case, it is possible to provide a display operation according to the level or purpose of the user by preparing a plurality of dedicated application softwares and selectively using them.

  In the water supply device 1 of the present embodiment described above, the distance L2 between the plate portion 104 of the cover 102 of the cabinet 10 and the wireless communication board 79 is smaller than the distance L1 between the plate portion 104 and the operation / display board 78. Therefore, it is possible to prevent the operation panel 76 from being erroneously operated due to the opening and closing of the cover 102 or an impact on the cabinet 10, and to perform excellent wireless communication with the external device by the communication unit 790 with the cover 102 closed. be able to. Further, since the control unit 70 including the wireless communication board 79 is housed in the cabinet 10, the waterproofness, durability, and robustness of the water supply device 1 can be secured.

(First Modification)
FIG. 10 is a diagram illustrating a control unit and an external device according to a first modified example. The control unit 70A of the first modified example has a control unit-side antenna unit 791 instead of the communication unit 790 and an integrated circuit 782 connected to the control unit-side antenna unit 791. This is different from the control unit 70 of the embodiment. The integrated circuit 782 is electrically connected to a storage unit 701 having a nonvolatile value storage area and a volatile storage area.

  The external device 170 according to the first modification includes a display-side antenna unit 171 for transmitting and receiving radio waves, a display unit 172, a battery 173, and a data reader 174. In the external device 170, the data received by the display-side antenna unit 171 is read by the data reader 174. Then, data (for example, target pressure, current pressure, etc.) read by the data reader 174 is displayed on the display unit 172. The battery 173 supplies power to the display-side antenna unit 171, the data reader 174, and the display unit 172.

  As the external device 170, for example, a general-purpose terminal device such as a smartphone, a mobile phone, a personal computer, and a tablet may be used, or a dedicated terminal device such as a remote monitor may be used. In particular, if a general-purpose terminal device such as a smartphone is used as the external display device, the cost of producing a dedicated display device can be reduced, so that the cost of the water supply device can be reduced. In addition, since a plurality of users can display the state of the water supply device 1 on each general-purpose terminal device, it is possible to provide a display operation according to the level or purpose of the user. For example, it is possible to provide a low-cost water supply device that can inform a user who does not have specialized knowledge about the water supply device such as a condominium or building manager with information on control of the pumps 12a and 12b in an easy-to-understand manner.

When the display-side antenna unit 171 generates a radio wave in a state where the external device 170 is close to the control unit 70A (communication unit 790), the control unit-side antenna unit 791 receives the radio wave,
The control unit-side antenna unit 791 converts radio waves into electric power. This power is supplied to the integrated circuit 782 and the storage unit 701 to drive the integrated circuit 782 and the storage unit 701. The integrated circuit 782 reads the data stored in the storage unit 701 and sends the data to the control unit-side antenna unit 791. The control unit-side antenna unit 791 transmits a radio wave to the display-side antenna unit 171 together with the data. The data reader 174 reads the data received by the display-side antenna unit 171 and causes the display unit 172 to display the data.

  The external device 170 may include a clear button 176 for deleting a display and a reset button (not shown) for resetting data. When the user presses the clear button 176, the information display (for example, the target pressure, the current pressure, and the like) related to the control of the pumps 12a and 12b displayed on the display unit 172 is deleted. When the reset button is pressed, a reset signal is transmitted to the control unit 70A, and the control unit 70A that has received the reset signal resets data such as abnormality determination of the pumps 12a and 12b and other maintenance information. Accordingly, when the water supply device 1 is stopped due to a slight abnormality, the water supply device 1 can be returned using the external device 170 without opening the cover 102 of the cabinet 10. The reset button may be used, for example, to stop a buzzer that sounds when a failure occurs in the water supply device 1. By doing so, the user can stop the buzzer using the external device 170 without opening the cover 102 of the cabinet 10. Although the clear button 176 of the present embodiment is a virtual button that appears on the screen of the display unit 172, the clear button 176 may be a mechanical button provided outside the display unit 172. Although the control unit 70A of the first modification does not include the clear button, the control unit 70A may include a clear button and a reset button.

  The operation of clearing the display and resetting the data may be restricted. Specifically, the clear button 176 is provided on the external device 170 mainly used by the user, and the reset button is provided on the control unit 70A mainly used by the maintenance staff. By providing the reset button only in the control unit 70A as described above, it is possible to prevent the user who operates the external device 170 from erroneously operating the reset button. By providing the external device 170 instead of a method of releasing a complicated use restriction such as a password, it is possible to prevent a reset due to a user's erroneous operation.

  Further, the external device 170 may be provided with an E button (not shown) for energy saving. When the E button of the external device 170 is pressed, the water supply device 1 is operated in the energy saving mode. Further, the operation in the energy saving mode may be canceled by pressing the E button of the external device 170 while operating in the energy saving mode. By doing so, the water supply device 1 can be set in the energy saving mode without opening the cover 102 of the cabinet 10 to save energy, and the energy saving mode can be canceled when the user feels insufficient pressure by the energy saving mode.
