Description

The present invention relates to a display method for displaying the state of a water tank, a setting method for setting a water tank water level control method for a pump device, a pump device, a pump system, and a display device.

Pump devices include water supply devices that supply tap water to water supply targets in buildings and the like, devices that use fire extinguishing pumps in fire extinguishing equipment, and devices that use submersible pumps installed in water tanks in drainage facilities and the like.

As an example of a pump device, a water supply device is widely used to supply tap water to a water supply target such as a building. As the water supply method of the water supply device, the water in the water receiving tank in which the water of the water main is stored is pressurized by the pump to the water supply target, and the water is supplied to the pump by using the main pressure of the water main. There is known a direct water supply system that supplies water to a water supply target by increasing the pressure. In addition, there are two types, one is a direct delivery type that directly supplies the conveyed liquid boosted by a pump to the water supply target, and the other is that the conveyed liquid boosted by a pump is sent to an elevated water tank installed on the roof of the building and stored in the elevated water tank. There is an elevated water tank system that supplies the water to the water supply target. The elevated water tank system is mainly used as a direct water supply system.

The water tank system includes a water tank one-tank type consisting of one water tank and a water tank two-tank type consisting of two water tanks communicating with each other by a communication pipe provided with a sluice valve. is there. Further, in general, a water level gauge for detecting the water level is provided in a water tank such as a water receiving tank or an elevated water tank that stores a transport liquid. As a water level gauge, for example, one having a plurality of electrode rods is known, and in a water supply device, an alarm such as full water, low water, or drought in a water tank is output based on detection signals by the plurality of electrode rods.

The method of using the electrode rods provided in the water tank is variously changed depending on the number of water receiving tanks of the water supply device, the installation environment such as the inflow method of city water, and the usage environment. For this reason, conventionally, a code indicating the number of water tanks of the water supply device and the inflow method of city water, and a program for controlling the water supply device corresponding to the code are provided so that various usage methods can be easily supported. , Are stored, and a water supply device that controls according to the input of a code by an operator has been proposed (see Patent Document 1).

When installing the water supply device, wiring and connection are made between a plurality of electrode rods installed in the water tank and the water supply device. In order to prevent such erroneous wiring of a plurality of electrode rods to the water supply device, a water supply device that detects the water level of the water tank based on the number of energizations between the electrode rods has been conventionally proposed (see Patent Document 2). Further, in order to prevent a malfunction caused by a circuit abnormality of the water level gauge, a water supply device that outputs an abnormal signal to the outside when there is an incompatible combination of detection signals from a plurality of electrode rods has been proposed ( See Patent Document 3).

Further, as a pump device using a submersible pump, a pump device capable of automatically operating the submersible pump by detecting the water level in the water tank in which the pump is installed by a float switch has been proposed. (See Patent Document 4)

Japanese Patent No. 4080913 Japanese Unexamined Patent Publication No. 2000-18188 Japanese Unexamined Patent Publication No. 2006-161791 Japanese Unexamined Patent Publication No. 2006-283739

As described above, the water supply device outputs a water level abnormality alarm based on the detection signals from the plurality of electrode rods of the water level gauge. However, for example, the conventional method of displaying full, low, or dry water with a lamp may be difficult for a user who is unfamiliar with the water supply device to understand the current water level or alarm of the aquarium.

Further, as described above, when the water supply device is installed, the operator makes an electrical connection between the plurality of electrode rods and the water supply device. Here, particularly in a water supply device that can handle different numbers of water tanks and different number of electrode rods, the operator first finds out the number of water tanks to be used and the number of electrode rods from the list described in the instruction manual. .. Then, the operator sets the water supply device and makes wiring connections between the plurality of electrode rods and the water supply device while looking at the code and wiring diagram corresponding to the number of water tanks and the number of electrode rods used from the instruction manual. Do. Such settings and wiring connections have been a cumbersome task for workers who are unfamiliar with the construction of water supply equipment, such as building managers. Further, even when a setting error or a wiring error of the water tank or the water level gauge is detected, the operator is required to confirm the setting or the wiring while referring to the instruction manual, and the operator is required to perform complicated work. Was there. In addition, since water is involved in the installation work of the water supply device, there is a concern that the paper medium such as the instruction manual may get wet and be damaged.

Also, even in a pump device using a submersible pump, it is necessary to check the water level detected by the float switch in order to check whether the water level in automatic operation is correct, and it is said that the work of checking the water level is to be simplified. There is a request.

The present invention has been made in view of the above circumstances, and provides a method, a pump device, a pump system, or a display that can easily check the state of the water tank for storing the conveyed liquid of the pump device or the electrical wiring. One of the purposes is to make a proposal.

Such a pump device is a control unit that acquires the water level of the water tank that stores the transport liquid of the pump as being above or below the water level, which is the threshold of the water level, and controls the water level according to the water level state determined based on the acquired water level. To be equipped. Then, the control unit has a communication unit that communicates with a display that displays the water level of the water tank, and the communication unit transmits water level information including at least a water level based on the water level to the display. It is a feature. According to such a pump device, water level information including the water level based on the water level level is transmitted to the display, so that the state of the water tank can be easily visually confirmed by the display of the display displaying the water level of the water tank. ..

The water tank stores the transport liquid of the pump, and the water tank water level is controlled by the pump device provided with the pump based on the water tank system and the water level of the water tank. The pump device uses at least one water level based on the water tank method as the threshold of the water level in the water tank, and determines whether the water level obtained from the water level gauge for measuring the water level in the water tank is equal to or lower than the water level. The water tank water level is controlled based on the water level state of the water tank. Then, in the display method, a water level graphic that imitates the water level and a control operation graphic for showing the control operation of the pump device with respect to the water level state of the water tank are displayed together.

FIG. 1A is a diagram showing an example of a schematic configuration of a water supply system including a water supply device. This water supply system includes a water supply device 10 (pump device) and two water tanks 110A and 110B, and mainly supplies water to a building (water supply target) such as an apartment, an office building, a commercial facility, or a school. It is a system for. In the example shown in FIG. 1A, the water supply device 10 is used in a water tank system (two water tanks) in which two water tanks 110A and 110B are installed on the suction side (primary side). However, the water supply device 10 of the present embodiment can also be used in a water receiving tank system (water receiving tank one tank type) in which one water receiving tank is installed on the primary side. The "water tank method" is an example of the "water tank method". A water supply pipe 107 is connected to the discharge side (secondary side) of the water supply device 10, and the water supply pipe 107 communicates with each water faucet (for example, a faucet) of a building (not shown). The water supply device 10 pressurizes the water stored in the water tanks 110A and 110B from a water main which is a water supply source (not shown), and supplies water to each water tap of the building.

The two-tank water tank type shown in FIG. 1A will be described in detail. In the two-tank type of water receiving tank, two water receiving tanks 110A and 110B are used. Water from the water mains (not shown), which is a water supply source, is stored in the two water receiving tanks 110A and 110B by the inflow pipes 130A and 130B branched from the introduction pipe 102 communicating with the water mains. City water inflow valves 132A and 132B are provided in the inflow pipes 130A and 130B, respectively. The city water inflow valves 132A and 132B are valves that can shield the flow paths of the inflow pipes 130A and 130B, and are composed of, for example, an electromagnetic valve and an electric valve. In the present embodiment, the city water inflow valves 132A and 132B are controlled by the output signal from the I / O unit 47 of the water supply device 10. The water receiving tank 110A is installed downstream of the inflow pipe 130A provided with the city water inflow valve 132A, and when the city water inflow valve 132A is opened, the water in the introduction pipe 102 flows into the water receiving tank 110A. Further, the water receiving tank 110B is installed downstream of the inflow pipe 130B provided with the city water inflow valve 132B, and when the city water inflow valve 132B is opened, the water of the introduction pipe 102 flows into the water receiving tank 110B. To do.

The water receiving tanks 110A and 110B and the suction port 10A of the water supply device 10 are connected by introduction pipes 116A and 116B. The introduction pipes 116A and 116B are provided with sluice valves 118A and 118B that can be opened and closed manually, respectively. When the sluice valve 118A is opened, the water receiving tank 110A and the water supply device 10 communicate with each other, and when the sluice valve 118B is opened, the water receiving tank 110B and the water supply device 10 communicate with each other. As a result, the water stored in one or both of the water receiving tanks 110A and 110B is introduced into the water supply device 10 according to the opening and closing of the sluice valves 118A and 118B.

Further, the water receiving tanks 110A and 110B are connected to each other by a communication pipe 112 provided with a water stop valve 114. The water stop valve 114 is composed of, for example, a sluice valve. When the water stop valve 114 is open, the water receiving tanks 110A and 110B have the same water level, and when the water stop valve 114 is closed, the water receiving tanks 110A and 110B are independent. It becomes the water level.

Each of the water receiving tanks 110A and 110B is provided with a first water level gauge which is a water level gauge for detecting the water level in the water receiving tank 110A and a second water level gauge which is a water level gauge for detecting the water level in the water receiving tank 110B. .. Specifically, an electrode type level switch 120A (first water level gauge) and an electrode type level switch 120B (second water level gauge), which are water level gauges for detecting the water level in the water receiving tanks 110A and 110B, are provided. In the present embodiment, the water supply device 10 has at least one water level as a threshold of the water level in the water receiving tanks 110A and 110B, and determines whether the water level in the water receiving tanks 110A and 110B is equal to or higher than the water level or lower than the water level. The water level is controlled in the water tank. Specifically, the water level based on the water tank method (setting code P10) described later is, for example, the drought water level, the reduced water level, and the open water level assigned to the electrodes of the electrode type level switches 120A and 120B in ascending order of water level. The water level, the closed water level, and the full water level. The water supply device 10 determines that the water level is "reduced" when the water level in the receiving tanks 110A and 110B is lower than the drought water level at which the pump 20 is forcibly stopped, and the water level is further lowered. When the water level becomes lower than the predetermined water level (drought water level) at which the pump 20 is forcibly stopped, the water level state is determined to be "drought state". Further, the water supply device 10 determines that the water level state is the "full state" when the water level becomes equal to or higher than the full water level at which the water may overflow. The control unit 40 has a set value for whether or not to detect a decrease in water. If the control unit 40 does not detect a decrease in water, the water level in the water tank is equal to or higher than the drought water level and lower than the full water level. The state is "normal state". On the other hand, when the control unit 40 detects a decrease in water, if the water level in the water tank is equal to or higher than the reduced water level and lower than the full water level, the water level is in the "normal state".

The detection signals by the electrode type level switches 120A and 120B are input to the I / O unit 47 of the water supply device 10. Each of the electrode type level switches 120A and 120B includes a plurality of electrode rods 121 to 125 arranged in the water receiving tanks 110A and 110B, respectively. The plurality of electrode rods 121 to 125 are water level detectors, and in the present embodiment, the common electrode rod 121, the electrode rod 122 for detecting the drought water level, and the city water in the order in which the low water level can be detected. Electrode rod 123 for detecting the open water level that opens the inflow valves 132A and 132B, electrode rod 124 for detecting the closed water level that closes the city water inflow valves 132A and 132B, and for detecting the full water level. It is the electrode rod 125 of. The electrode type level switches 120A and 120B are not limited to those having five electrode rods 121 to 125, and may have three, four, or six or more electrode rods. Even in that case, it is preferable to detect the drought water level with the electrode rod capable of detecting the lowest water level, and detect the full water level with the electrode rod capable of detecting the highest water level. Further, the open water level for opening the city water inflow valves 132A and 132B may be a water level lower than the closed water level for closing the city water inflow valves 132A and 132B.

Here, the electrode type level switch 120A (first water level gauge), the electrode type level switch 120
In B (second water level gauge), the water surface of the water tank is raised from the lower end of each electrode rod 122 to 125 by detecting the change in the resistance value between each electrode rod 122 to 125 and the longest common electrode rod 121. Is designed to detect that it is in a high position. That is, when the water surface of the water receiving tanks 110A and 110B is higher than the lower ends of the electrode rods 122 to 125, and at least a part of the water surface is conducted between the electrode rods 122 to 125 below the water surface and the common electrode rod 121 by water. The detection signal of each water level or higher is output to the I / O unit 47 described later. On the other hand, when the water surface of the water receiving tanks 110A and 110B is lower than the lower ends of the electrode rods 122 to 125, all the portions thereof are not conducted by water between the electrode rods 122 to 125 on the water surface and the common electrode rods 121. Therefore, the detection signals of each water level or higher output to the I / O unit 47, which will be described later, are turned off.

Each of the water receiving tanks 110A and 110B is provided with float switches 140A and 140B which are water level gauges for detecting the water level in the water receiving tanks 110A and 110B in place of or in addition to the electrode type level switches 120A and 120B. May be good. The detection signals by the float switches 140A and 140B are input to the control unit 40 of the water supply device 10, and the pump device 10 has a water level of at least one water level (drought, city water inflow valves 132A and 132B) of the water receiving tanks 110A and 110B. It is judged that the water level is above or below the open water level, closed water level, or full water level. A plurality of float switches 140A and 140B may be provided when the water supply device 10 detects the drought water level, the open and closed water level of the city water inflow valves 132A and 132B, or the full water level.

The city water inflow valves 132A and 132B may be opened and closed without going through the control unit 40. Specifically, the above-mentioned water level gauge is provided with an output unit such as a relay contact connected to the city water inflow valves 132A and 132B, and the city water inflow valves 132A and 132B can be opened and closed from the output unit of the water level gauge. It is controlled by the signal of. The output unit of each water level gauge turns on the signal to open the corresponding city water inflow valves 132A and 132B when the city water inflow valves 132A and 132B are detected below the open water level level, and the city water inflow valves 132A and 132B The signal for opening the corresponding city water inflow valves 132A and 132B may be turned off (that is, the city water inflow valves 132A and 132B are closed) when the water level level or higher is detected.

Next, the water supply device 10 connected to the downstream (secondary side) of the water receiving tanks 110A and 110B will be described. The water supply device 10 has a first water tank mode in which water is supplied using the water tank 110A, a second water tank mode in which water is supplied using the water tank 110B, and a sluice valve 118B described later as the water tank mode. The water tank 110A and the water tank 110B are used in both water tanks to supply water. In the present embodiment, in the water supply device 10, either "No1", "No2", or "shared" is selected by the water tank selection button 441 (FIG. 1D) by an external input to the water tank control operation display unit described later. To. Then, the water supply device 10 has a first water tank mode when No. 1 is selected in the water tank selection, a second water tank mode when No2 is selected, and a water tank shared mode when shared is selected. To do. It should be noted that such a water tank mode can be changed only when the water supply device 10 is used in the water tank two-tank type, and when the water supply device 10 is used in the water tank one-tank type, the first water tank mode is used. It should be fixed with.

The check valve 23 is provided in the discharge pipe 32 connected to the discharge port of the pump 20 to prevent backflow of water when the pump 20 is stopped. A flow switch 24 is provided on the downstream side of the check valve 23. The flow switch 24 is a flow rate detector that detects that the flow rate of water flowing through the discharge pipe 32 has dropped to a predetermined value, that is, an insufficient amount of water (small amount of water). A pressure sensor 26 and a pressure tank 28 are provided on the downstream side of the flow switch 24 in the discharge pipe 32. The pressure sensor 26 is a pressure measuring device for measuring the discharge pressure of the pump 20 (hereinafter, the discharge pressure indicates a pressure value measured by the pressure sensor 26).

The operation panel 44 is a GUI (graphical user interface) capable of displaying and changing various data stored in the storage unit 41 via the calculation unit 42. Specifically, the operation panel 44 displays device information, setting value information, maintenance information display and setting change, maintenance information, history information display, input, history clearing, abnormality information display and reset, and water tank water level information. , And display driving information. The control unit 40 and the operation panel 44 may be configured on the same substrate, or may be separate substrates. In the case of separate boards, the control unit 40 and the operation panel 44 may be connected by serial communication, by wire such as a signal line, or wirelessly. Further, the operation panel 44 is installed in a place away from the water supply device 10 (for example, a manager's room), and the operation panel 44 is provided with a CPU to control display operations by the CPU, or the control unit 40 and Communication control with the external display 80 may be performed.

The setting unit 45 of the operation panel 44 is an information input unit of the control unit 40, and is an external operation from the user to start / stop the automatic water supply in the water supply device 10, select the water tanks 110A and 110B, reset the alarm, and the like. It is used to perform various input operations such as changing the settings of various data. The setting unit 45 may include operation buttons, a touch panel, or the like. Here, in the present embodiment, the input through the setting unit 45, the input through the I / O unit 47, and the input through the communication unit 48 are referred to as external inputs. Information input by an external operation through the setting unit 45 is stored in the storage unit 41. For example, the setting unit 45 can change the setting of the water receiving tank method, the water supply method of the water supply device 10, the set pressure PA, the minimum pressure PB, the starting pressure, and the stopping pressure as set value information.

The display unit 46 of the operation panel 44 functions as a user interface and is configured to be able to display various data stored in the storage unit 41. The water supply device 10 may be installed in an environment with a lot of electrical noise such as a machine room or a pump room. In preparation for such a case, the display unit 46 may use a display composed of a 7-segment LED or an indicator lamp that is more resistant to electrical noise than a liquid crystal display and a touch panel, and a mechanical pressing button. As a result, even in an external environment where an abnormality occurs in the display operation unit 80A of the external display 80 due to electrical noise or the like, the minimum display necessary for the operation of the water supply device 10 is displayed on the display unit 46. Can be done. Therefore, the water supply device 10 can be installed even in an environment with a lot of electrical noise. However, the display unit 46 is not limited to a display device that is resistant to electrical noise, and a liquid crystal display device or a touch panel based on a dot matrix method may be used.

FIG. 1D is a diagram showing an example of the operation panel 44 of the present embodiment. As shown in the figure, the operation panel 44 of the present embodiment has a water level alarm display unit 150 and a water tank control operation display unit 160. The water tank control operation display unit 160 has a water tank selection button 441 and indicator lamps L3 and L4. The water tank selection button 441 is, for example, a tact switch, and by pressing the operator, one of "No. 1", "No. 2", and "shared" can be selected as the water tank selection, and the selected receiver can be selected. The state of water tank selection is indicated by lighting one or both of the indicator lamps L3 and L4. That is, when "No. 1" is selected in the water tank selection, only the indicator lamp L3 is lit, and when "No. 2" is selected, only the indicator lamp L4 is lit, and "shared" is selected. When it is set, both the indicator lamps L3 and L4 are lit. The water level alarm display unit 150 has indicator lamps L1 and L2. The water level alarm may be indicated by lighting or blinking of the indicator lamp L1 or L2. Specifically, when the water level of the water receiving tank selected as the water receiving tank selection is full, the indicator lamp L1 lights up as a full water alarm. Further, the indicator lamp L2 blinks as a water reduction alarm when the selected water tank water level is in a low water level, and the indicator lamp L2 lights up as a drought alarm when the selected water tank water level is in a drought state. To do. The water tank selection may be changed by an external input to the communication unit 48 or the I / O unit 47 in place of or in addition to the one changed by the water tank selection button 441.

The communication unit 48 is configured to be able to communicate with the external display 80 by wired communication or wireless communication. Specifically, various information about the water supply device 10 stored in the storage unit 41 is transmitted to the external display 80, and the setting change of the set value information from the external display 80 is received as the information input unit of the control unit 40. Then, it is sent to the calculation unit 42. As the wireless communication in the communication unit 48, for example, a technique of short-range wireless communication (NFC: Near Field Communication) can be used. In addition, any type of wireless communication such as Bluetooth (registered trademark) and Wi-Fi (registered trademark) can be used. However, NFC is advantageous in that communication can be completed only by bringing the control unit 40 and the external display 80 close to each other. Further, as for wired communication, for example, the control unit 40 may be provided with an external connection terminal such as USB (Universal Serial Bus), and communication may be performed by connecting the external display 80 to the external connection terminal, RS422, Serial communication such as RS232C and RS485 may be used.

The external display 80 (display) has a display operation unit 80A, and is configured to be able to display and change various data related to the water supply device 10 by communicating with the communication unit 48 of the water supply device 10. Specifically, the external display 80 receives various data stored in the storage unit 41 from the communication unit 48 of the water supply device 10 and displays them on the display operation unit 80A. Further, the external display 80 transmits a change request of various data input by the user by operating the display operation unit 80A to the communication unit 48 of the water supply device 10. The display operation unit 80A can employ a high-performance display on a liquid crystal screen using a touch input method or a press button method. In this case, the display unit 46 of the water supply device 10 may display simple information, and the external display 80 may display a large amount of information. With such a configuration, the external display 80 has a plurality of information (for example, a water tank system graphic and a water level display, a set pressure PA, a minimum pressure PB, a starting pressure, a stopping pressure, which will be described later) among various data stored in the storage unit 41. The target pressure SV, the current pressure PV, the start / stop of the pump 20, the rotation speed, etc.) can be displayed on the same screen of the display operation unit 80A. As a result, even a user who is unfamiliar with the water supply device 10 can recognize the state of the water supply device 10 and input settings without misunderstanding.

Further, when a general-purpose terminal device (PDA: personal digital assistant) such as a smartphone, a mobile phone, a personal computer, or a tablet is adopted as the external display 80, it acts as the external display 80 on these PDAs. You may install the dedicated application software of. In this case, a plurality of dedicated application software may be prepared according to the user's level or purpose. Further, it is preferable that the external display 80 can be connected to various networks 90, and can download dedicated application software or transmit information acquired from the water supply device 10 to the outside via the network 90.

It should be noted that all the functions of the operation panel 44 described above may be performed by the external display 80. In this way, even if the water supply device 10 is installed in a place where it is difficult to operate (for example, the operation panel 44 is near the operator's feet), it is easy to check the status of the water supply device 10 and change the set value information. ..

Next, an example of water supply control of the water supply device 10 by the control unit 40 will be described. When the discharge pressure drops below a predetermined starting pressure while the drought state has not occurred and the pump 20 is stopped, the control unit 40 starts at least one of the pumps 20. Specifically, the control unit 40 issues a command to the motor 21 (inverter if the inverter is provided) to start driving the pump 20. During the operation of the pump 20, control such as estimated terminal pressure constant control or target pressure constant control is performed by the set pressure (set pressure PA). Specifically, in the case of constant estimated terminal pressure control, the control unit 40 discharges the pump 20 by using the rotation speed of the pump 20 and the target pressure control curve so that the pressure at the end of the water supply destination becomes constant. Set the target pressure SV for the pump pressure. In the case of constant target pressure control, the control unit 40 sets the set pressure PA as the target pressure SV so that the pressure on the discharge side of the pump 20 becomes the set pressure PA. Further, in both the estimated terminal pressure constant control and the target pressure constant control, the control unit 40 sets the discharge pressure as the current pressure PV and performs PI calculation or PID calculation based on the deviation between the target pressure SV and the current pressure PV. Calculates the command rotation speed of the pump 20. In the estimated terminal pressure constant control, the set pressure PA is the pressure value at the maximum flow rate, and the minimum pressure PB is the pressure value at the terminal faucet at zero flow rate. Further, when there are a plurality of pumps as in the present embodiment, the control unit 40 also controls the number of pumps according to the amount of water by the number of pumps that can be started at the same time (the number of pumps operating in parallel). The number of pumps operating in parallel may be stored in the storage unit 41 as set value information.

When the use of water in the building is reduced during the operation of the pump 20, the flow switch 24 detects that the discharge flow rate from the pump 20 has reached less than the insufficient amount of water, and the detection signal is transmitted via the I / O unit 47. It is sent to the control unit 40. Upon receiving this detection signal, the control unit 40 performs an accumulator operation that controls the rotation speed of the pump 20 so that the discharge pressure reaches the stop pressure in a predetermined time. Then, when the discharge pressure reaches a predetermined stop pressure, it is determined that the pressure has been accumulated in the pressure tank 28, the accumulator operation is terminated, and the pump 20 is stopped (small amount of water is stopped). After the small amount of water is stopped by the pump 20, when water is used again in the building and the discharge pressure drops below the starting pressure, the small stop restart of the pump 20 is performed. When there are a plurality of pumps as in the present embodiment, it is preferable to rotate the starting pump 20 to prevent water from staying in the pump 20. Further, as a method for detecting a small amount of water, other means such as a low load based on the current value of the motor 21 and a deadline lift may be used without using the flow switch 24.

Further, in the present embodiment, the control unit 40 determines information such as the number of water receiving tanks and the number of electrodes of the electrode type level switches 120A and 120B by referring to the current setting code P10 which is a water tank type. To execute water tank control. Specifically, when the setting code P10 is "9", as shown in FIGS. 1B and 1C, the control unit 40 determines that the water tank is a two-tank type and the number of electrode rods is five. Then, the control unit 40 determines each electrode rod of the electrode type level switches 120A and 120B input to each input terminal. In the control unit 40, the common electrode rod 121 is connected to the input terminal E15, the input terminal E14 is connected to the electrode rod 122 for detecting the drought water level, and the input terminal E13 is connected to the electrode rod 123 for detecting the open water level. An electrode rod 124 for detecting the closed water level is connected to the input terminal E12, and an electrode rod 125 for detecting the full water level is connected to the input terminal E11. Similarly, the level switches 120B are connected to the input terminals E25 to E21. It is determined that the electrode rods 121 to 125 are connected.

Then, the control unit 40 sets the water levels of the water tanks 110A and 110B based on the detection signals of the electrode type level switches 120A and 120B input to the input terminals E11 to E15, E31 to E33, E21 to 25, and E41 to E43. Judgment is made, and water tank control (water tank water level control) is executed based on the determined water level. That is, the control unit 40 is determined based on at least one water level level (for example, full water level, low water level, dry water level) acquired from the electrode type level switches 120A and 120B (for example, full water state, low water state). The water level of the water tank is controlled according to the drought condition. Water tank control includes opening / closing control of city water inflow valves 132A and 132B, forced stop of pump 20 due to drought condition, display of water level alarm on operation panel 44, external display 80, etc., and external output of water level alarm, etc. At least one of is included. In the case of the two-tank water tank type, the control unit 40 determines the water level of the water receiving tank 110A based on the detection signal of the electrode type level switch 120A in the first water tank mode, and the electrode type level switch 120B in the second water tank mode. It is advisable to determine the water level of the water receiving tank 110B based on the detection signal of. Further, in the shared mode, the control unit 40 may determine the water level of the water tanks 110A and 110b based on the detection signals of one of the electrode type level switches 120A and 120B determined in advance, or both detection signals may be used. The water level of the water receiving tanks 110A and 110b may be determined based on the above. In addition, as one embodiment, in the case of the water tank one-tank type, the control unit 40 determines the water level of the water tank 110A based on the detection signal of the electrode type level switch 120A, and executes the water tank control (water tank water level control). To do.

Next, a method of displaying the status of the water receiving tanks 110A and 110B will be described. In the following description, as an example, a method of displaying the status of the water tanks 110A and 110B on the display operation unit 80A of the external display 80 will be described. In this case, the control unit 40 transmits the water level information including the income water level state and the water tank system to the external display 80. Further, the status of the water receiving tanks 110A and 110B may be displayed by the display unit 46 (operation panel 44) of the control unit 40 in addition to or instead of the external display 80. When displayed on the operation panel 44, the operation panel 44 has the same configuration and function as the external display 80. In other words, the method for displaying the states of the water receiving tanks 110A and 110B described below may be executed by the control unit 40 of the water supply device 10, may be executed by the operation panel 44, or may be executed by the water supply device 10. It may be executed by the external display 80 which can acquire information from the control unit 40 of the above. The operation panel 44 and the external display 80 are examples of display operators. Further, the method of displaying the status of the water tanks 110A and 110B is not limited to the one executed by a single device, and may be executed by combining the functions of a plurality of devices.

This process is performed at predetermined timings when the user operates the external display 80 to instruct the water level display of the water tanks 110A and 110B in a state where communication between the external display 80 and the water supply device 10 is established. It is executed every (for example, every few msec to several hundred msec, every few seconds, etc.).

When the water level display process is executed, the external display 80 acquires the water tank system (water tank system) and the water levels of the water tanks 110A and 110B (step: S12). The processing of S12 by the external display 80 is performed by receiving information from the water supply device 10. In the present embodiment, the external display 80 acquires the value of the setting code P10 (water tank setting) as the water tank method. In general, once the water tank system is set, it is not changed thereafter. Therefore, the external display 80 receives the water tank system from the water supply device 10 only once when the water level display screen is activated and is not shown. The water tank system may be acquired by storing in a storage unit and then referring to its own storage unit. Regarding the water level information of the water receiving tanks 110A and 110B, the external display 80 is a water level detection signal (for example, full water level) based on the water level level by the electrode type level switch 120A and / or 120B from the control unit 40 of the water supply device 10. Above or below, below or below the water reduction level, above or below the drought level, etc.).

The water tank system graphic unit 1120 further includes a control operation arrow unit 1130 indicating water tank control for a detected water level based on a plurality of electrode rods, a character information unit 1140 indicating a control operation for each water level state, a full state, a low water state, or a drought state. Water level alarm display unit 1150 indicating status information (water level alarm display), water tank control operation display unit 1160 indicating the status of water tank selection, water tank setting information display unit 1110 displaying the value of setting code P10, and setting code. It has an information display unit 1111 that simply indicates the control corresponding to the value of P10. Then, on each display unit, information indicating water tank control for the detected water level based on a plurality of electrode rods, text information indicating the control operation for each water level state, water level alarm display, water tank selection status, water tank setting information, and Information that simply indicates the control corresponding to the value of the setting code P10 is displayed together with the water tank type graphic unit 1120 on one screen.

In the example shown in FIG. 3, the water tank type graphic unit 1120 on one screen has a control operation arrow unit 1130 that imitates the control operation for the water level state of each electrode rod, and a character information unit 1140 that represents the control operation for each water level state. Is also displayed, indicating the water receiving tank control for the detected water level based on a plurality of electrode rods. As a result, even an operator who is unfamiliar with the water supply device 10 can check on one screen what kind of water level alarm is output by which electrode rod according to the value of the current setting code P10, so that the water tank can be controlled. Can be easily confirmed.

Further, in the example shown in FIG. 3, the external display 80 also shows a button 1441 for selecting a water tank and a water tank method selection button 1170 for a water tank setting process described later. The water tank method selection button 1170 may be configured to be displayed only to a person having a specific authority. Specifically, the operator can display the water tank method selection button 1170 by a specific procedure such as inputting a password. This makes it possible to prevent an unauthorized person from accidentally changing the settings. If the water tank system is changed to an incorrect value and a drought is falsely reported, the water supply will stop and the water supply destination will be cut off. Further, the external display 80 is not limited to such an example, and may display at least a part of the above-mentioned information, or may display different information together.

The water level display is displayed to show the user the water level information acquired in step S12. The water level display may be displayed so that the user can recognize the water level information, and various forms of display can be adopted.

As an example, the external display 80 may have a water level graphic unit 86 that displays a water level graphic that imitates the water level of the water tank, and the water level display may be displayed by the water level graphic. In FIG. 3, the water level graphic unit 86 displays the current water level information by a thick horizontal bar which is an example of the water level graphic. The water level graphic imitates the water surface of the water receiving tank 110A, and in the example shown in FIG. 3, the lower end of the electrode rod (above the open water level) shown by the graphic 1123 and the lower end of the electrode rod (below the closed water level) indicated by the graphic 1124. It is shown that there is the current water level of the receiving tank 110A between. That is, the water level graphic uses the graphic 1122 to 1125 and the water level level display unit 1128, which are examples of the water level graphic, to display whether the water level is above or below the water level. By displaying the water level display using the water level level graphic in this way, the current state of the water level can be easily visually confirmed.

The external display 80 acquired the water level based on the following water level levels (1) to (4) from the control unit 40 as the water level information (step S12 in FIG. 2).
(1) Less than the full water level (no continuity between electrode rod 121 and electrode rod 125)
(2) Below the closed water level (no continuity between the electrode rod 121 and the electrode rod 124)
(3) Above the open water level (with continuity between the electrode rod 121 and the electrode rod 123)
(4) Above the drought water level (with continuity between the electrode rod 121 and the electrode rod 122)
Therefore, in step S14 of FIG. 2, the external display 80 determines that there is a water surface between the electrode rod 121 and the electrode rod 123 and the electrode rod 124 that switch between the presence and absence of continuity, and the water level graphic unit 86 has the electrode rod 123. A thick horizontal bar (water level graphic) imitating the water surface (water level based on the water level) is displayed between the lower end of the graphic 1123 imitating and the lower end of the graphic 1124 imitating the electrode rod 124, and the water level state is normal. Judge that it is in a state.

Further, the water level graphic unit 86 determines and displays whether the current water level state is a normal state, a full water state, a low water state, or a drought state based on the received water level information, and displays the water level character information unit 87. It is advisable to indicate whether the current water level information is in a normal state, a full state, a low water state, or a drought state as text information. In FIG. 3, by displaying "water level (normal)" on the water level character information unit 87 arranged side by side with the thick horizontal bar of the water level graphic unit 86, it is indicated that the current water level information is in the normal state. It is shown in. The external display 80 has a water level character information unit 87 in addition to the water level graphic unit 86, and by displaying the water level graphic and the water level character information, the user can display the current water level of the water receiving tank on paper such as an instruction manual. It can be recognized more accurately than using a medium.

Here, regarding the information displayed on the display unit 46 of the water supply device 10, such as full water, low water, or drought, the display on the external display 80 may be the same as the display on the water supply device 10 (FIGS. 1D and FIG. 3). That is, the water level alarm display unit 1150 is a graphic that imitates the water level alarm display unit 150 in the display unit 46 of the water supply device 10, and the water tank control operation display unit 1160 is a graphic that imitates the water tank control operation display unit 160. Lamp display units L1001 and L1002 imitating the display lamps L1 and L2 of the display panel 44 are arranged on the water level alarm display unit 1150, and the water tank control operation display unit 1160 has a button display 1441 imitating the water tank selection button 441. And the lamp display units L1003 and L1004 imitating the display lamps L3 and L4 of the display panel 44 are arranged. Specifically, the display of each lamp display unit L1001, L1002, L1003, L1004 is displayed in a color (for example, black) indicating extinguishing when each indicator lamp L1, L2, L3, L4 is extinguished. When the indicator lamps L1, L2, L3, and L4 are lit, they are displayed in a color indicating lighting (for example, yellow). In this way, the display on the external display 80 can be easily understood, especially for a person who is accustomed to the display on the display unit 46 of the water supply device 10.

FIG. 4 is a diagram showing an example of a state display of the water receiving tank when the water level state is full. The external display 80 has acquired the water level information that the water level state of the water receiving tank 110A is full, that is, the electrode rod 125 of the electrode type level switch 120A is submerged in water. In this case, as shown in FIG. 4, the water level graphic portion 86 is indicated by a thick horizontal bar above the lower end of the electrode bar 125.

The external display 80 acquired the water level based on the following water level levels (1) to (4) from the control unit 40 as the water level information (step S12 in FIG. 2).
(1) Above the full water level (with conduction between the electrode rod 121 and the electrode rod 125)
(2) Closed water level or higher (with conduction between electrode rod 121 and electrode rod 124)
(3) Above the open water level (with continuity between the electrode rod 121 and the electrode rod 123)
(4) Above the drought water level (with continuity between the electrode rod 121 and the electrode rod 122)
Therefore, in step S14 of FIG. 2, the external display 80 determines that the water surface is at a height higher than the lower end of the electrode rod 125 because all the electrode rods are electrically connected to the electrode rod 121, and the water level graphic unit 86 has a water level graphic unit 86. , A thick horizontal bar (water level graphic) imitating the water surface (water level based on the water level) is displayed above the lower end of the graphic 1125 imitating the electrode rod 125, and it is determined that the water level state is full.

Here, the water level graphic 86 may have a display format different from that when the water level information is in the normal state when the water level information is full. For example, when the water level information is in the normal state, the water level graphic 86 is shown in the first display format (first color such as black, blue, green, and / or lit) and acquired from the control unit 40. When the water level based on the water level information is full, the water level graphic 86 is displayed in a second display format (second color such as red, yellow, and / or highlighting such as lighting, blinking, enlarged display, etc.). Shown. In this way, the user who sees the display of the external display 80 can be easily notified of the full state.

Further, "water level (full water)" is displayed on the water level character information unit 87 arranged side by side with the water level graphic 86 part, indicating that the current water level information is in a full water state. The water level character information unit 87 may also perform highlighting such as the second display in the water level graphic 86. Further, in the display 80 shown in FIG. 4, the water level alarm display unit 150 in the display unit 46, the water level alarm display unit 1150 imitating the full water alarm of the water tank control operation display unit 160, and the water tank control operation display unit 1160 are also shown. There is. Specifically, with the issuance of the full water alarm, the display color of the lamp display unit L1001 changes from the first display color (for example, black) indicating the normal state to the second display color (for example) different from the first display color. For example, it is changed to yellow). The second display color of the lamp display unit L1001 may be the same color as the display lamp L1 of the display panel 44. In this way, it is possible to make the display of the full water alarm on the external display 80 easy to understand, especially for those who are accustomed to the display on the display unit 46 of the water supply device 10.

FIG. 5 is a diagram showing an example of a state display of the water receiving tank when the water level information is in a drought state. The external display 80 has acquired water level information that the water receiving tank 110A is in a drought state, that is, the electrode rod 122 of the electrode type level switch 120A is exposed from water. In this case, as shown in FIG. 5, in the water level graphic unit 86, a thick horizontal bar (water level graphic) is shown between the lower end of the graphic 1121 and the lower end of the graphic 1122.

The external display 80 acquired the water level based on the following water level levels (1) to (4) from the control unit 40 as the water level information (step S12 in FIG. 2).
(1) Less than the full water level (no continuity between electrode rod 121 and electrode rod 125)
(2) Below the closed water level (no continuity between the electrode rod 121 and the electrode rod 124)
(3) Below the open water level (no continuity between the electrode rod 121 and the electrode rod 123)
(4) Below the drought water level (no continuity between electrode rod 121 and electrode rod 122)
Therefore, in step S14 of FIG. 2, the external display 80 determines that the water surface is at a height below the lower end of the electrode rod 122 because all the electrode rods are not electrically connected to the electrode rod 121, and the water level graphic unit 86 determines that the water surface is above the lower end. A thick horizontal bar (water level graphic) imitating the water surface (water level based on the water level) is displayed below the lower end of the graphic 1122 imitating the electrode rod 122, and it is determined that the water level state is a drought state.

Here, when the water level state determined by the water level information acquired from the control unit 40 is a drought state in which the pump is forcibly stopped, the external display 80 displays a display different from that when the water level information is in the normal state. It may be in the form. For example, when the water level state is normal, the water level graphic 86 is shown in the first display format (first color such as black, blue, green, and / or lit), and when the water level state is drought. , The water level graphic 86 may be shown in a third display format (third color such as red, yellow, and / or lighting, blinking). When the water level state is drought, the display of the water level graphic unit 86 which is the same as or similar to that when the water level state is full may be adopted, or the display of a different water level graphic unit 86 may be adopted. Good. Further, in FIG. 5, the water level character information unit 87 arranged side by side with the water level graphic unit 86 displays “water level (drought)” to indicate that the current water level state is a drought state. There is. In this way, the user who sees the display of the external display 80 can be easily notified of the drought state, as compared with the case where the indicator lamp L2 indicates the drought.

Further, in the display 80 of FIG. 5, a water level alarm display unit 1150 imitating a drought alarm in the display unit 46 and a water tank control operation display unit 1160 are also shown. Specifically, with the issuance of the drought warning, the display color of the lamp display unit L1002 changes from the first display color (for example, black) indicating the normal state to the second display color (for example) different from the first display color. For example, it is changed to yellow). The second display color of the lamp display unit L1002 may be the same color as the display lamp L2 of the display panel 44. In this way, the display of the drought warning on the external display 80 can be easily understood, especially for a person who is accustomed to the display on the display unit 46 of the water supply device 10.

Further, the external display 80 may display the abnormality of the water level gauge when the abnormality has occurred in the water level gauge. For example, if there is a contradiction in the detection of the water level state by the acquired water level gauge, the external display 80 may determine that the water level gauge has an abnormality and display the abnormality of the water level gauge. However, the external display 80 may be capable of acquiring a signal indicating an abnormality of the water level gauge from the control unit 40 of the water supply device 10.

The external display 80 of FIG. 6 is a diagram showing an example of a state display of the water tank when an abnormality occurs in the water level gauge. As an example, in the external display 80, from the control unit 40, the electrode rod 122 that detects the lowest water level among the electrode rods is exposed from water, and the electrode rod 125 that detects the highest water level is immersed in water. We have acquired contradictory water level information that the water level is full and that it occurs at the same time. In this case, as shown in FIG. 5, the water level graphic unit 86 has a thick horizontal bar (water level graphic) indicating a full state above the lower end of the graphic 1125 and a drought state below the lower end of the graphic 1122. A thick horizontal bar (water level graphic) indicating is shown. Further, the external display 80 has an abnormality display unit 1180, and the abnormality display unit 1180 displays “electrode abnormality” to indicate that an abnormality has occurred in the water level gauge.

The external display 80 acquired the water level based on the following water level levels (1) to (4) from the control unit 40 as the water level information (step S12 in FIG. 2).
(1) Above the full water level (the electrode rod 121 and the electrode rod 125 are conductive)
(2) Above or below the closed water level (with or without continuity between the electrode rod 121 and the electrode rod 124)
(3) Above or below the open water level (with or without continuity between the electrode rod 121 and the electrode rod 123)
(4) Less than the drought water level (with continuity between electrode rod 121 and electrode rod 122)
Therefore, in step S14 of FIG. 2, the external display 80 determines that the water surface is above the lower end of the electrode rod 125 because the electrode rod 125 is electrically connected to the electrode rod 121, and the electrode rod 125 is used as the water level graphic 86. A thick horizontal bar that imitates the water surface (water level based on the water level) is displayed above the lower end of the graphic 1125 that imitates. Further, the external display 80 determines that the water surface is at a height below the lower end of the electrode rod 122 because the electrode rod 122 does not conduct with the electrode rod 121, and the water level graphic 86 is a graphic 1122 that imitates the electrode rod 122. A thick horizontal bar that imitates the water surface (water level based on the water level) is further displayed below the lower end of.

In the example shown in FIG. 6, the water level graphic unit 86 indicates the water surface (water level based on the water level) by thick horizontal bars above the lower end of the graphic 1125 and below the lower end of the graphic 1122. By such a display, the external display 80 can indicate that the water level acquired from the control unit 40 is inconsistent.

Further, the water level character information unit 87 arranged next to the thick line horizontal bar above the lower end of the graphic 1125 of the water level graphic unit 86 has "water level (full water)", and the thick line horizontal bar below the lower end of the graphic 1122. "Water level (drought)" is displayed on the water level character information unit 87 arranged side by side. In this way, the user can determine which electrode has the abnormality.

In the example shown in the external display 80 of FIG. 6, a drought warning and a full water warning are shown together on the water level warning display unit 1150. Specifically, with the issuance of the full water alarm, the display color of the lamp display unit L1001 changes from the first display color (for example, black) indicating the normal state to the second display color (for example) different from the first display color. For example, it is changed to yellow). Further, with the issuance of the drought warning, the display color of the lamp display unit L1002 changes from the first display color (for example, black) indicating the normal state to the second display color (for example, yellow) different from the first display color. Is changed to. The second display color of the lamp display unit L1001 may be the same color as when the display lamp L1 of the display panel 44 is lit. The second display color of the lamp display unit L1002 may be the same color as when the display lamp L2 of the display panel 44 is lit. In this way, the display of the electrode abnormality on the external display 80 can be easily understood, especially for a person who is accustomed to the display on the display unit 46 of the water supply device 10.

FIG. 7 is a diagram showing another example of the state display of the water tank. In the external display 80 of FIG. 7, the water level in the water receiving tank is located between the lower end of the electrode rod 123 and the lower end of the electrode rod 124, as in FIG. However, in the example shown in FIG. 7, the graphics 1121 to 1123 of the electrode rods (electrode rods below the water surface) 121 to 123 that are submerged in the water in the water tank and the water that is not submerged in the water tank, that is, from the water The display format is different between the exposed electrode rods (electrode rods on the water surface) 124 and 125, and the graphics 1124 and 1125. In other words, on the external display 80, the electrode rod below the water surface and the electrode rod above the water surface are displayed separately. In the example shown in FIG. 7, the graphics 1121 to 1123 showing the electrode rods 121 to 123 which are the electrode rods on the water surface are shown in the first electrode display format (for example, the display color is blue and / or lighting), and the water surface is shown. The graphics 1124 and 1125 showing the electrode rods 124 and 125, which are the upper electrode rods, are shown in a second electrode display format different from the first color (for example, the display color is green and / or blinking). By displaying the electrode rods above the water surface and the electrode rods below the water surface separately in this way, it is possible to inform the detection by the water level gauge in an easy-to-understand manner, particularly for a person who is unfamiliar with the water supply device 10.

FIG. 8 is a diagram showing still another example of the state display of the water tank. As shown in the external display 80 of FIG. 8, the water tank type graphic unit 1120 imitates both water tanks 110A and 110B regardless of whether the first water tank mode or the second water tank mode is shared. The water tank type graphic units 1120A and 1120B may be displayed.

Further, as shown in the external display 80 of FIG. 8, the external display 80 has character information units 88A and 88B that indicate the amount of water in the water tanks 110A and 110B as character information such as numbers as water level information. Then, the amount of water in the water tanks 110A and 110B may be indicated by character information such as numbers. In the example shown in FIG. 8, the character information unit 88 (88A, 88B) displays the ratio (60%) of the water level to the full water level, but the present invention is not limited to such an example, and the water level, the amount of water, etc. May be indicated numerically.

As described above, the display of the state of the water tank described with reference to FIGS. 3 to 8 and the like may be made on the display unit 46 of the water supply device 10. In this case, the display unit 46 may acquire the water tank system (water tank system) and the water tank water level (water tank water level) by referring to the storage unit 41 or inputting a signal through the I / O unit 47 (water tank system). FIG. 5, S12). Then, similarly to the display on the external display 80 described above, in the display unit 46, the water tank type graphic unit 1120 and the water level display unit 86 are arranged on the same screen, and the water tank type graphic and the water level display are displayed together. Good (S14).

As described above, in the present embodiment, the external display 80 or the control unit 40 of the water supply device 10 acquires the water tank system of the water supply device 10 and acquires the water levels of the water tanks 110A and 110B from the water level gauge. Then, the external display 80 and / or the control unit 40 of the water supply device 10 in which the water tank system graphic unit 1120 and the water level display unit 86 are arranged on the same screen have acquired the water tank system graphic that imitates the acquired water tank system. The water level display for showing the water level of the water tank is also displayed. With such a state display of the water receiving tank, the state of the water receiving tank can be easily visually confirmed, and even a person unfamiliar with the water supply device 10 can easily grasp the state of the water receiving tanks 110A and 110B.

In addition, the water level based on the water level such as full, closed, open, low, etc. of the water tanks 110A and 110B detected by the water level gauge is acquired, and the water level is controlled by the water level based on the water level. The control unit 40 has a communication unit 48 that communicates with an external display 80 (display operator) that displays the water levels of the water tanks 110A and 110B, and the communication unit 48 includes a water level including at least a water level based on the water level. The information is transmitted to the external display 80. As a result, the display actuator that communicates with the communication unit 48 acquires more detailed water level information such as which electrode is exposed from the water surface as compared with the water level alarm that indicates only the full water state, the low water state, and the drought state. can do. In addition, this makes it possible to display the water level that causes the wiring error of the water level gauge or the abnormality of the electrode. For example, as shown in the above embodiment, the external display 80 connected to the communication unit 48 displays the water level corresponding to the water level (for example, the water level display unit 86 and the water level character information unit 87 of FIGS. 3 to 8). Can be displayed to the operator. Further, in one embodiment, a control logic according to the water level may be assembled by an external device connected to the communication unit 48, and the control logic may be incorporated into the control unit 40 to increase the options for water tank water level control. In this way, the water tank water level control can be changed or added during the operation of the water supply device 10.

Next, a method of changing the setting of the water tank system in the water supply device 10 will be described. In the following description, as an example, a method of setting the water tank system of the water supply device 10 by using the external display 80 will be described. However, the setting of the water tank system may be performed through the operation panel 44 of the water supply device 10 without using the external display 80. In other words, the operation panel 44 has the same configuration as the external display 80, and the method of setting the water tank system described below may be executed by the user operating the operation panel 44. It may be executed by the user operating the external display 80.

FIG. 9 is a flowchart showing an example of the water tank setting process. The water tank setting process, which is an example of the water tank setting process, is started by, for example, a user performing a predetermined specific operation for changing the setting of the water tank method on the external display 80. In the present embodiment, when the water tank method selection button 1170 is pressed, the water tank setting process is started.

When the water tank setting process is started, first, as a display step, the external display 80 graphically displays the water tank method that can be selected in the water supply device 10 (step: S22). Here, the selectable water tank type graphic display includes at least one of a water tank type graphic display and a water level gauge type graphic display. As an example, the external display 80 visualizes the configuration corresponding to the setting code P10, which is an example of the water tank system as shown in the water tank system graphic unit 1120 (control operation arrow unit 1130, character information unit 1140). Graphically display what you have done. The external display 80 may receive and display a selectable water tank system from the control unit 40 of the water supply device 10.

Subsequently, as an input step, the operator selects (inputs) the water tank method by operating the external display 80 that graphically displays the water tank method (step: S24). The water supply device 10 of the present embodiment uses any one of a plurality of water tank systems (15 types in FIG. 1B) so that the water supply device 10 can correspond to various usage modes as shown in FIG. 1B described above. It can be selected and the water level state based on the selected water tank method can be displayed on the same screen. Then, according to the method of the present embodiment, the selectable water tank method is graphically displayed, so that the operator can display the graphic while viewing the graphic display in which the water tank control is visualized by the control operation arrow portion 1130 or the like. The water tank method can be selected on the same screen as. Therefore, even a person who is unfamiliar with the water supply device 10 can easily select the water tank method.

Then, when the water tank method is selected by the operator, the external display 80 sets the water tank method based on the input by the operator (step: S26) as a setting step. Next, it is judged whether or not all the settings such as the water tank code, water level gauge code, solenoid valve code, and city water inflow valve control code included in the water tank method have been completed, and if there are any items that have not been set ( Step: S28 is No), returns to the display step (S22), and when all the settings are completed (step: S28 is Yes), the external display 80 controls the water tank system set in step: S26 to control the water supply device 10. It is transmitted to the unit 40 (step: S30). The control unit 40 controls the water tank based on the water tank system received from the external display 80. In the present embodiment, when all the settings are completed (step: S28 is Yes), the external display 80 transmits the water tank system set in step: S26 to the control unit 40 of the water supply device 10 (step). : S30). However, in one embodiment, after the setting step (step: S26), the set value may be transmitted to the control unit 40, and the process may return to the display step (S22) to perform the next setting.

Hereinafter, a specific example of the water tank setting process shown in FIG. 9 will be shown. In the present embodiment, the external display 80 is composed of a touch panel, and the operator can select various settings of the water tank system corresponding to the graphic display by directly pressing the graphic display on the display operation unit 80A. It is said. However, the present invention is not limited to such an example, and the external display 80 may be provided with a virtual operation button corresponding to the graphic display of the water tank system on the touch panel, and the operator inputs a set value by character input or voice input. Therefore, various settings of the water tank system may be selected. Further, the external display 80 may have a mechanical switch (not shown), and the operator may operate the mechanical switch of the external display 80 to select various settings.

(First setting means of the water tank method)
FIG. 9A is a flowchart showing an example of the setting process by the first setting means. 10A to 10D are diagrams for explaining the first setting means of the water tank system. Specifically, the first example of a graphic display (FIG. 9: step S22) imitating a selectable water tank system by the external display 80 and a selection by an operator (FIG. 9: step S24) will be described. It is a figure for doing.

The first setting means by the external display 80 is FIG. 10A, which is a screen for setting the water tank code, FIG. 10B or FIG. 10C, which is a screen for setting the electrode code and the solenoid valve code, and the city water inflow valve control code is set. The setting code P10 is set based on each value of the water tank system which is configured by FIG. 10D and is set in the order of the following first step and second step shown in FIG. 9A.
First step: Setting of water tank code (FIG. 9A: step S42)
Second step: Setting of the electrode cord and the solenoid valve cord (step S44)
Further, only when the water receiving tank system set in the first step is a two-tank system and the city water inflow valve system set in the second step is a solenoid valve (step S46: Yes), the following third step is performed. Will be executed. This is because if the water receiving tank system is a one-tank type (step S46: No), the city water inflow valve control code is determined "independently", so there is no need to set the city water inflow valve control code, and the city water inflow. This is based on the fact that it is not necessary to set the city water inflow valve control code unless the valve system is a solenoid valve (step S46: No).
Third step: Setting of city water inflow valve control code (FIG. 9A: step S48)
In this embodiment, the city water inflow valves 132A and 132B are controlled by the setting code P10 based on the detection by the water level gauge. Therefore, in the above example, the electrode code and the solenoid valve code are set as an example of setting the water level gauge code in the second step. However, the present invention is not limited to these examples, and for example, only the electrode cord may be set in the second step. If the water receiving tank method set in the first step is a one-tank type or a two-tank type and the city water inflow valve method set in the second step is a ball tap (step S56: No), the above-mentioned first step.

(Fig. 9: S26). Here, in the case of the one-tank type, since the city water inflow valve control code is only "single", the external display 80 determines that all the settings of the water receiving tank method have been completed (FIG. 9: S28 is Yes, FIG. 9A). : S46 is No), the process proceeds to step S30 of FIG. 9, the selected water tank system is transmitted to the water supply device 10, and the water tank system is set in the water supply device 10. Further, as a result, the setting process by the first setting means in FIG. 9A is completed.

FIG. 10C shows an example of the display of the external display 80 when the two-tank type is selected in FIG. 10A in the display step of the second step. The external display 80 has a graphic display unit 400 that imitates a water tank system that can be selected by a two-tank system, and when the two-tank system is set in the setting step of the first step (FIG. 9A: S42), the following In the display step of the second step (FIG. 9A: S44), a graphic display unit 400 imitating a water tank system that can be selected by a two-tank system is displayed (FIG. 9: S22). As shown in FIG. 1B, in the present embodiment, the setting codes P10 = "7" to "11" and "13" to "15" are two water tanks, and in the graphic display unit 400, the setting code P10 = Graphic display 410 corresponding to 7, graphic display 420 corresponding to setting code P10 = 8, graphic display 430 corresponding to setting code P10 = 9 or 13, graphic display 440 corresponding to setting code P10 = 10 or 14, setting code The graphic display 450 corresponding to P10 = 11 or 15 is displayed. Specifically, the graphic display 410 has display areas 411, 421, 413, 414, 415, the display area 411 is the character information of the value of the setting code P10, and the display area 412 is the character of the water tank system and the electrode code. Information, the display area 413 is a schematic diagram of the electrode rod (the water level level display unit (broken line) is also shown), the display area 414 is an arrow indicating the control operation for each water level state, and the display area 415 is for each water level state. Character information indicating the control operation is shown. The graphic displays 420, 430, 440, and 450 also have display areas 421-425, 431-435, 441-445, and 451-455 similar to the graphic display 410. In this way, the graphic display unit 400 displays a graphic imitating the electrode rods for each setting code P10, and also shows information on water tank control according to the water level detected by the plurality of electrode rods. There is. Then, the operator looks at the graphic display and selects the water tank system of the water supply device 10 (FIG. 9: S24).

In the input step of the second step, the operator can select the electrode cord and the solenoid valve cord by directly pressing any one of the graphic displays 410, 420, 430, 440, 450 (FIGS. 9: S24, 9A). : S42).

When pressed, "electrode cord = 4 + 3 and solenoid valve cord = city water inflow type solenoid valve" is selected. When the operator presses the graphic display 450, "electrode code = 5 + 3 and solenoid valve code = city water inflow type solenoid valve" is selected. Then, in the setting step of the second step, the selected electrode cord and solenoid valve cord are set (FIG. 9: step S26).

In the present embodiment, only the control method of the city water inflow valves 132A and 132B is different between the case where the value of the setting code P10 is "9" to "11" and the case where the value is "13" to "15". The number of water tanks and the number of electrode rods (electrode cords) are the same. Therefore, when "9" to "11" and "13" to "15" are set as the values of the setting code P10 in the setting step of the second step, the operator moves to FIG. 10C in the second step. After selecting the corresponding water tank method, the external display 8
For 0, it is necessary to carry out the third step and set the city water inflow valve control code which is the control method for the city water inflow valves 132A and 132B. Therefore, after the second step, the external display 80 shifts to a screen for displaying the control method of the city water inflow valves 132A and 132B, which is the display step of the third step, in FIG. 9: Step S28 becomes No. .. That is, as described above, when the two-tank system is selected as the water receiving tank system in the first step and the solenoid valve is set as the city water inflow valve system in the second step (FIG. 9A: S46 is Yes). The process shifts to the process of the third step for setting the city water inflow valve control code (FIG. 9A: S48). Specifically, in FIG. 10C of the second step, when the operator selects any of the graphic displays 430, 440, and 450, the external display 80 then shifts to the third step and displays. The graphic display 500 of FIG. 10D for selecting the control method of the city water inflow valves 132A and 132B is displayed in the step. On the other hand, in FIG. 10B of the second step, when the graphic display 410 or 420 (setting code P10 = "7" or "8") is selected by the operator, after the second step is completed, FIG. 9: S28 is No. Then, the external display 80 shifts to step S30 of FIG. 9, transmits the set water tank system to the water supply device 10, and the water supply device 10 also sets the water tank system. Further, at this time, it is determined that the city water inflow valve method is not a solenoid valve (FIG. 9A: S46 is No), and the setting process by the first setting means is completed.

FIG. 10D is an example of the display of the external display 80 in the display step of the third step when the graphic display 450 (setting code P10 = “11” “15”) is selected in FIG. 10C which is the second step. Shown. In the display step in the third step, the external display 80 has a graphic display unit 500 for displaying for selecting the control method of the city water inflow valves 132A and 132B, and the control method of the city water inflow valves 132A and 132B.

Further, only when the water receiving tank system set in the first step is a two-tank system and the city water inflow valve system is a solenoid valve (step S56: Yes), the following second step is executed. This is because if the water receiving tank system is a one-tank type (step S56: No), the city water inflow valve control code is determined "independently", so there is no need to set the city water inflow valve control code, and the city water inflow. This is based on the fact that it is not necessary to set the city water inflow valve control code unless the valve system is a solenoid valve (step S56: No).
Second step: Setting of city water inflow valve control code (FIG. 9B: step S58)
If the water receiving tank method set in the first step is a one-tank type or a two-tank type and the city water inflow valve method is a ball tap (step S56: No), the above-mentioned second step is omitted and the water receiving tank is used. The second setting means of the method ends.

When the water tank setting process is started by pressing the water tank method selection button 1170 or the like, the external display 80 carries out the first step (FIG. 9B: 52). In the first step, as a display step, the external display 80 displays a screen for setting the water tank code, the electrode code, and the solenoid valve code shown in FIG. 11 (FIG. 9: S22). Specifically, the external display 80 has a graphic display unit 600, and among the settings included in the water tank system, the values of the water tank code, the electrode code, and the solenoid valve code excluding the city water inflow valve control code are set. A graphic display showing the combined configuration is displayed on the graphic display unit 600. In the graphic display unit 600, the graphic displays 310 to 350 shown in FIG. 10B and the graphic displays 410 to 450 shown in FIG. 10C are shown together. In FIG. 11, the same graphic display as the graphic display of FIGS. 10A to 10D has the same reference numerals as those of FIGS. 10A to 10D.

Here, when any one of the graphic displays 310-350, 410, 420 of the graphic display unit 600 shown in FIG. 11 is selected by the operator (step S24 in FIG. 9), the water receiving tank system is a one-tank system. Since it is not necessary to set the city water inflow valve control code because it is either present or the city water inflow valve is not a solenoid valve (FIG. 9B: S56: No), it is set in the setting step of the first step. The code P10 = "1" to "5", "7", or "8" is set, and the first step is completed. Then, step S28 in FIG. 9 becomes Yes in order to omit the second step, and the external display 80 shifts to step S30 in FIG. 9 to transmit the selected water tank method to the water supply device 10 to supply water. The water tank system is set in the device 10.

Further, in the input step of the first step, any one of the graphic displays 430 to 450 (setting code P10 = "9" to "11", "13" to "15") of the graphic display unit 600 shown in FIG. Is selected (step S24 in FIG. 9), the selected value is set in the setting step of the first step, then step S28 in FIG. 9 becomes No, and the process proceeds to the second step. Since the city water inflow valve control code is selected in the second step, the same display as in FIG. 10D (step S24 in FIG. 9) is displayed as in the third step of the first setting means, and the city water inflow is performed. The control method of the valves 132A and 132B is selected (step S24 in FIG. 9). That is, when the two-tank system is selected as the water receiving tank system and the solenoid valve is set as the city water inflow valve system in the first step (FIG. 9B: S56 is Yes), the city water inflow valve control code is set. (Fig. 9B: S58). Then, when the control method of the city water inflow valves 132A and 132B is selected by the operator (FIG. 9B: S58), step S28 in FIG. 9 becomes Yes, and the external display 80 shifts to step S30 in FIG. Then, the corresponding water tank system is transmitted to the water supply device 10, and the water tank system is set in the water supply device 10.

Similar to FIG. 10B, the graphic display unit 600 shown in FIG. 11 displays the same graphic for the water tank system in which only the control methods of the city water inflow valves 132A and 132B are different (see graphic display 430 to 450). .. However, in one embodiment, different graphic displays may be made for the water tank system in which only the control methods of the city water inflow valves 132A and 132B are different. Specifically, the graphic display unit 600 displays a graphic that imitates the configuration of the setting code P10 = "1" to "15".

(Third setting means of the water tank method)
FIG. 9C is a flowchart showing an example of the setting process by the third setting means. 12A and 12B are diagrams for explaining a third setting means of the water tank system.

First step: Setting of the electrode cord and the solenoid valve cord (FIG. 9C: step S62)
Second step: Setting of water tank code (step S64)
Further, only when the water receiving tank system set in the second step is a two-tank system and the city water inflow valve system set in the first step is a solenoid valve (step S66: Yes), the following third step is performed. Will be executed. This is because if the water receiving tank system is a one-tank type (step S66: No), the city water inflow valve control code is determined "independently", so there is no need to set the city water inflow valve control code, and the city water inflow. This is based on the fact that it is not necessary to set the city water inflow valve control code unless the valve system is a solenoid valve (step S66: No).

When the graphic display 910 is selected by the operator in the input step of the second step (FIG. 9: S24, FIG. 9C: S64), the external display 80 is set to the corresponding water tank in the setting step of the second step. The method is transmitted to the water supply device 10, and the water tank system is set in the water supply device 10. In this case, after the completion of the second step, FIG. 9: S28 becomes No, and the external display 80 shifts to step S30 of FIG. 9 and transmits the set water tank system to the water supply device 10. , The water tank system is also set in the water supply device 10. Further, at this time, it is determined that the water receiving tank system is not a two-tank system (FIG. 9C: S66 is No), and the setting process by the third setting means is completed. On the other hand, when the graphic display 920 is selected by the operator in the input step of the second step (FIG. 9: S24, FIG. 9C: S64), the external display 80 carries out the third step and inflows of city water. It is necessary to set the city water inflow valve control code, which is the control method for the valves 132A and 132B. Therefore, after the second step, the external display 80 shifts to a screen for displaying the control method of the city water inflow valves 132A and 132B, which is the display step of the third step, in FIG. 9: Step S28 becomes No. .. That is, as described above, when the two-tank system is selected as the water receiving tank system in the second step and the solenoid valve is set as the city water inflow valve system in the first step (FIG. 9C: S66 is Yes), The process shifts to the process of the third step for setting the city water inflow valve control code (FIG. 9C: S68). Specifically, in FIG. 12B of the second step, when the operator selects the graphic display 920, the external display 80 then shifts to the third step, and in the display step, the city water inflow valve 132A, The display (FIG. 9: S24) similar to that shown in FIG. 10D for selecting the control method of 132B is displayed. Then, in the input step of the third step, the control method of the city water inflow valves 132A and 132B is selected (step S24 in FIG. 9). Then, when the control method of the city water inflow valves 132A and 132B is selected by the operator, the external display 80 sets the control method of the selected city water inflow valves 132A and 132B in the setting step in the third step. Set. Further, step S28 in FIG. 9 becomes Yes, and the external display 80 shifts to step S30 in FIG. 9 to transmit the corresponding water tank system to the water supply device 10, and the water supply device 10 sets the water tank system. Is done.

Similar to FIG. 10B, the graphic display unit 600 shown in FIG. 12A displays the same graphic for the water tank system in which only the control methods of the city water inflow valves 132A and 132B are different (see graphic displays 81 to 850). .. However, in one embodiment, different graphic displays may be made for water tank systems having different control methods for the city water inflow valves 132A and 132B.

In the first to third setting means of the water tank system described above, the external display 80 may graphically display the set water tank system when the operator completes the setting of the water tank system. Further, the external display 80 is set in the control unit 40 to confirm whether or not the correct value is set in the control unit 40 after transmitting the water tank system to the water supply device 10 in step S30 of FIG. It is preferable to receive the received water tank system and display a graphic corresponding to the received water tank system. By doing so, the operator can visually confirm the set water tank system, and can suppress erroneous setting of the water tank system. Further, when displaying the set water tank method graphically, the water level information of the water tank is acquired from the water level gauge, and as described with reference to FIGS. 4 to 8, the water tank method imitating the water tank method. The graphic unit 1120 and the water level display unit 86 for showing the water level information may be displayed together. By doing so, when there is a contradiction in the detection of the water level gauge, for example, as shown in FIG. 6, "electrode abnormality" is displayed on the electrode abnormality portion 1180, so that the operator may make a mistake in setting the water tank method. , It is possible to know an error in the electrical connection between the plurality of electrode rods and the water supply device 10.

As described above, the graphic display of the water tank system described with reference to FIGS. 10A to 12B and the like may be made on the display unit 46 of the water supply device 10. In this case, the operator may operate the setting unit 45 of the water supply device 10 while looking at the graphic display of the display unit 46 to set the water tank system of the water supply device 10.

The graphic that imitates the above-mentioned water level gauge method may be determined based on the water level gauge method provided in the water tanks 110A and 110B, and is not limited to the graphic that imitates a plurality of electrode rods. Specifically, it is preferable that a graphic imitating the water level gauge method is determined based on the water level gauge code included in the water tank system. As an example, when the water level gauge code stored in the storage unit 41 is a value indicating an electrode type level switch having five electrode rods, as shown in FIG. 3, the water tank type graphic unit 1120 has five. A diagram including graphics 1121 to 1125 imitating the electrode rods 121 to 125 of the above is displayed on the display operation unit 80A, while when the water level gauge code has a value indicating a float switch, the water tank type graphic unit is as shown in FIG. In the 1120, as a graphic display imitating the method of the water level gauge, a diagram including the graphic 2140 imitating the float switches 140A and 140B may be displayed on the display operation unit 80A.

In the example shown in FIG. 13, the water tank type graphic unit 1120 includes a graphic unit 2140 that imitates one of the float switches 140A and 140B, and a water level graphic unit 2128 that indicates a water level that is a water level threshold (in the example shown in FIG. 13). (Shown by a solid line), a control operation arrow part 2230 that imitates the control operation for the water level state in the float switches 140A and 140B, a character information part 2240 that indicates the control operation for each water level state, and a water receiving tank 110A (110B). It has a water level graphic unit 86 that displays a water level graphic that imitates the water surface of the above, a graphic that imitates one of the float switches 140A and 140B, and an arrow that imitates the control operation for the water level state in the float switches 140A and 140B. Textual information indicating the control operation for the water level state and a water level graphic imitating the water surface of the water receiving tank 110A (110B) are shown. Specifically, in the example shown in FIG. 13, the float switches 140A and 140B detect the open water level that opens the city water inflow valves 132A and 132B and the closed water level that closes the city water inflow valves 132A and 132B. It is shown that Then, in FIG. 13A, it is shown that the current water level of the water receiving tank 110A (110B) is between the open water level and the closed water level. Further, in FIG. 13B, it is shown that the current water level of the water receiving tank 110A (110B) is lower than the open water level. In this case, the signal for opening the city water inflow valve 132A (132B) is turned on. Further, FIG. 13C shows that the current water level of the water receiving tank 110A (110B) exceeds the closed water level. In this case, the signal for opening the city water inflow valve 132A (132B) is turned off (that is, the city water inflow valves 132A and 132B are closed).

(Second Embodiment)
FIG. 14 is a diagram showing an example of a water supply system according to the second embodiment. The water supply system 1000 of the second embodiment uses the water supply device 10 having the same configuration as that of the embodiment of FIG. 1A described above in the elevated water tank system. However, the water supply device 10 according to the second embodiment shall have an operation panel 44C instead of the operation panel 44 described above. The operation panel 44C is different from the operation panel 44C in the details such as the absence of the water tank control operation display unit 160.

In the present embodiment, the water supply device 10 communicates with the suction port 10a of the water main 100C or a water tank (not shown), and the transport liquid sent by the pump 20 is placed on the roof of the building 500C. Water is stored in the water tank 110C, and water is supplied to the water supply target (for example, a faucet) 501C in the building 500C by falling water from the elevated water tank 110C. A constant water level valve 232C is provided in the water supply pipe 107 connected to the discharge port 10b of the water supply device 10. The constant water level valve 232C is a valve capable of shielding the flow path of the water supply pipe 107, and is controlled to open and close so that the water level of the elevated water tank 110C is within a certain range (more than reduced water in the elevated water tank and less than full). For example, the constant water level valve 232C is composed of a solenoid valve, and is controlled to open and close by an output signal from the control unit 40 (I / O unit 47) of the elevated water tank type water supply device 10. The constant water level valve 232C may be opened and closed without going through the control unit 40.

The control unit 40 controls the water supply to the pump 20 in the elevated water tank system. Specifically, when the constant water level valve 232C is opened, the discharge pressure drops and the pump 20 starts. Then, when the constant water level valve 232C is closed, the control unit 40 detects with the flow switch 24 that the discharge flow rate of the pump 20 has reached less than the underwater amount Qmin, and stops the pump 20 with a small amount of water. If the constant water level valve 232C is not closed even if the water level of the elevated water tank 110C rises above the closed level after the pump 20 is started, the water in the elevated water tank 110C overflows and the residence of the building 500C. It causes secondary damage to such things. Therefore, the control unit 40 may forcibly stop the pump 20 when the water level is full.

Further, the control unit 40 determines the water level state of the elevated water tank 110C based on the signal of the water level gauge 120C, and executes control (water tank water level control) based on the determined water level state. The water tank water level control includes opening / closing control of the constant water level valve 232C, starting the pump 20 by opening the constant water level valve or reducing the water level, forcibly stopping the pump 20 when the water level is full, and water level (water reduction) to the operation panel 44C or the external terminal 80. , Localized water level valve open / closed, full water), and at least one such as an open / close signal of the constant water level valve 232C and an external output such as a water level alarm. In the second embodiment, the elevated water tank 110
In order to control the water level in the water tank of C, "30: with open / close control of the constant water level valve 232C" and "31: without open / close control of the constant water level valve 232C" are predetermined and set as setting values of the setting code P10. It is assumed that the control unit 40 executes the water tank water level control according to the setting of the code P10. When the set value of the setting code P10 is "30: with opening / closing control of the constant water level valve 232C" or "31: without opening / closing control of the constant water level valve 232C", the water supply device 10 sets at least as the threshold value of the water level of the elevated water tank 110C. The water tank water level is controlled in a water level state that has one water level and is determined by whether the water level in the elevated water tank 110C is equal to or higher than the water level or lower than the water level. The water level includes any of the reduced water level, the open water level, the closed water level, and the full water level assigned to the electrodes of the electrode type level switch 120C in ascending order of water level. If the water level in the elevated water tank 110C is less than the water level at which the water level in the water tank may be insufficient and the water may be cut off, the water level is judged to be "low water" and the water level is higher than the full water level at which water may overflow. When it becomes full, the water level is judged to be "full". If the water level in the aquarium is equal to or higher than the reduced water level and lower than the full water level, the water level is "normal". Further, the control unit 40 outputs an open / close command to the constant water level valve 232C to open the constant water level valve 232C below the open water level and close the constant water level valve 232C above the closed water level as the water tank water level control.

FIG. 15 is a diagram showing an example of the operation panel 44C of the second embodiment. As shown in the figure, the operation panel 44C has a water level alarm display unit 150C. The water level alarm display unit 150C includes indicator lamps L31 and L32, and as a water tank water level control, the water level alarm of the elevated water tank 110C may be indicated by lighting or blinking of the indicator lamps L31 and L32. Specifically, when the water level of the elevated water tank 110C is full, the indicator lamp L31 lights up as a full water alarm. Further, when the elevated water tank 110C is in a water-reduced state, the indicator lamp L32 lights up as a water-reduced alarm.

As an example, the external display 80 may perform a process of replacing the water receiving tanks 110A and 110B with the elevated water tank 110C in the process of FIG. 2 described above to display the water level of the elevated water tank 110C. That is, the external display 80 has a water tank system graphic unit 3120 and a water level display unit 86, and acquires the water tank system of the elevated water tank 110C and the water level of the elevated water tank 110C from the control unit 40, and imitates the acquired water tank system. The water tank system graphic is displayed on the water tank system graphic unit 3120, and the water level display for displaying the water level information is displayed on the water level display unit 86.

16 and 17 show an example of the water level display of the elevated water tank 110C. Here, FIG. 16 shows an example of a case where the constant water level valve control is performed by the control unit 40 as the water tank setting (the value of the setting code P10 is “30”), and FIG. 17 shows the water tank. An example is shown in the case where the constant water level valve control is not performed by the control unit 40 as a setting (the value of the setting code P10 is "31"). As in the first embodiment described above, the value of the setting code P10 for the elevated water tank 110C (setting code) in the water tank type graphic group 1120X and the relation group P10X1 of the storage unit 80B of the external display 80. It is assumed that the value of P10 is stored in advance so that the water tank type graphic corresponding to “30” or “31”) can be selected.

The external display 80 has a water tank type graphic unit 3120, and displays a graphic imitating a water level gauge (a plurality of electrode rods as an example). The graphic displayed on the graphic unit 3120 includes a graphic 3121 to 125 that imitates a plurality of electrode rods 121C to 125C provided in the elevated water tank 110C, and a line extending from the lower end of the graphic 3122 to 3125 to draw a water level level. The water level display unit 3128 shown by (broken line in the example shown in FIGS. 16 and 17) is included. Further, the water tank system graphic unit 3120 includes information 3130, 3140 indicating water tank water level control with respect to the detected water level based on the water level gauge, a water tank alarm display 3150 indicating information indicating full water, low water, or drought, a value 3110 of the setting code P10, and Information 3111 that simply indicates control over the value of P10 of the setting code is also shown. In the examples shown in FIGS. 16 and 17, the detected water level based on a plurality of electrode rods is used by using the arrow 3130 that imitates the control operation for the water level state in each electrode rod and the character information 3140 that represents the control operation for each water level state. The water level control of the elevated water tank 110C is shown. Further, in the examples shown in FIGS. 16 and 17, a setting button 3170 for changing the water tank system (value of the setting code P10) is also shown. The setting button 3170 may be configured to be displayed only to a person having a specific authority. Such a display improves the visibility of the operator.

Then, the screen of FIG. 18 is displayed, and the operator inputs the setting on the screen, so that the setting code P10 is set based on the setting of the water level gauge code. In this embodiment, the constant water level valve 232C is controlled based on the water level of the elevated water tank 110C detected by the water level gauge according to the setting code P10. Therefore, in FIG. 18 and the following description, the presence / absence of control of the constant water level valve 232C by the control unit 40 is set as an example of setting the water level gauge code. However, the present invention is not limited to these examples, and for example, an electrode code relating to the number of electrode rods may be set, or a water tank code relating to the number of elevated water tanks may be set.

The graphic display unit 3200 shown in FIG. 18 displayed in the display step has a graphic display 3210 showing a method in which the constant water level valve 232C is controlled by the control unit 40, and the constant water level valve 232C is controlled by the control unit 40.

Then, in the operation control circuit 4103 of the submersible pump 4201, the water level measured by the float switch 4210 is equal to or higher than the operation start water level level LV1, the water level state is set to the operation start water level state, the operation of the submersible pump 4201 is started, and water is stored in the water tank. When the water level measured by the float switch 4220 is the operation stop water level level LV2 or higher, the water level state is set to the stop water level state and the operation is stopped. The operation control circuit 4103 of the submersible pump 4202 sets the water level state to the operation start water level state at a rate of once every two times when the water level measured by the float switch 4230 is the operation start water level LV3 or higher, and starts the operation of the submersible pump 3202. Then, when the water level measured by the float switch 4240 falls below the stop water level LV4, the operation is stopped, and when the water level measured by the float switch 4250 exceeds the abnormal water level LV5, the water level state is changed to the abnormal water level and the operation is started. To do. With such a configuration, the submersible pump 4201 and the submersible pump 4202 are automatically operated alternately in the normal state, and the submersible pump 4201 and the submersible pump 4202 are started at the same time when the abnormal water level LV5 is exceeded.

As an example, the external display 80 may display the water level of the septic tank 4300 by executing the process of replacing the water receiving tanks 100A and 110B with the septic tank 4300 in the process of FIG. 2 described above. That is, the external display 80 acquires the septic tank system (water tank system) of the septic tank 4300 and the water level of the septic tank 4300, and the water tank system graphic unit 5120 imitating the acquired water tank system and the water level display for displaying the water level information. It has a unit 86 and displays a water tank system graphic and water level information.

FIG. 21 shows an example of the water level display of the septic tank 4300. Here, FIG. 21 shows an example when parallel alternating operation is set as the water tank setting (the value of the setting code P10 is “40”). As in the first and second embodiments described above, the storage unit 80B of the external display 80 has the value of the setting code P10 for the septic tank 4300 in the water tank type graphic group 1120X and the relation group P10X1. It is assumed that the corresponding aquarium graphic is stored in advance.
