The monitoring device 210 corresponds to an example of a "connection destination" of the water supply device 10. In the present embodiment, the water supply device 10 is installed in the pump room 100, and the monitoring device 210 is installed in the monitoring room 200 separate from the pump room 100. The monitoring room 200 may be provided on another floor in the same building as the pump room 100, or may be provided in a building different from the pump room 100. However, the present invention is not limited to these examples, and the monitoring device 210 may be installed in the pump chamber 100.

[Water supply method for water supply equipment]
Here, the water supply method of the water supply device 10 in the present embodiment will be described with reference to FIGS. 2 and 3. In both the examples of FIGS. 2 and 3, the monitoring device 210 is provided in the monitoring room 200 in the building 170. FIG. 2 is a diagram showing an example in which the water supply device 10 is used by the water receiving tank method. In the example shown in FIG. 2, the water supply device 10 is used in a water receiving tank 1 tank type in which one water receiving tank 160 is connected to the suction side (primary side). The water receiving tank 160, which is a water supply source, and the suction port 10A of the water supply device 10 communicate with each other by an introduction pipe 171. In the water receiving tank system, the water supply device 10 pressurizes the water stored in the water receiving tank 160 from a water main which is not shown as a water supply source by a pump, and supplies water to each water tap 172 of the building 170.

The water receiving tank 160 is provided with an electrode type level switch 162 as an example of a water level gauge that detects the water level in the water receiving tank 160. In the present embodiment, the water level in the water receiving tank 160 becomes "reduced" when the water level is higher than the drought water level at which the pump is forcibly stopped, and the water level becomes lower and the pumps 30A and 30B are forcibly stopped. When the water level is below the specified water level (dried water level), it becomes a "dried state". Further, when the water level exceeds a predetermined level (full water level) where there is a risk of overflowing water, the state becomes "full". The control unit 65 has a set value for whether or not to detect a decrease in water. If the control unit 65 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 information is "normal". On the other hand, when the control unit 65 detects the decrease in water, the water level information is "normal state" if the water level in the water tank is equal to or higher than the reduced water level and less than the full level.

The detection signal by the electrode type level switch 162 is input to the control unit 65 (I / O unit 70) of the water supply device 10 whose details will be described later. The electrode type level switch 162 includes a plurality of electrode rods 162a to 162e arranged in the water receiving tank 160. The plurality of electrode rods 162a to 162e are water level detectors, and open the common electrode rod 162a, the electrode rod 162b for detecting the drought water level, and the city water inflow valve 163 in the order in which the low water level can be detected. It becomes an electrode rod 162c for detecting the water level of the open water level, an electrode rod 162d for detecting the water level of the closed water level that closes the city water inflow valve 163, and an electrode rod 162e for detecting the water level of the full water level. There is. The electrode type level switch 162 is not limited to having five electrode rods 162a to 162e, 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 an electrode rod capable of detecting the lowest water level, and detect the full water level with an electrode rod capable of detecting the highest water level. Further, the water level for opening the city water inflow valve 163 may be a water level lower than the water level for closing the city water inflow valve 163.

Here, in the electrode type level switch 162, the water level in the water tank is set to the electrode rods 162b to 162e by detecting the change in the resistance value between each electrode rod 162b to 162e and the longest common electrode rod 162a. It is designed to detect that it is higher than the lower end. That is, when the water level of the water receiving tank 160 is higher than the lower end of each of the electrode rods 162b to 162e and the water is conducted between the electrode rods 162b to 162e and the common electrode rod 162a, the detection signal of each water level level is output. ..

The water receiving tank 160 may be provided with a float switch, which is a water level gauge for detecting the water level in the water receiving tank 160, in place of or in addition to the electrode type level switch 162. The detection signal by the float switch is input to the control unit 65 of the water supply device 10. A plurality of float switches may be provided in order to detect the drought water level, the open and closed water level of the city water inflow valve 163, or the full water level.

FIG. 3 is a diagram showing an example in which the water supply device 10 is used by the direct water supply system. In the example shown in FIG. 3, the water supply device 10 is used in a direct water supply direct delivery type that supplies water to a water tap 172 that is a water supply target by increasing the pressure with a pump using the main pressure of the water main 173. There is. A pressure sensor 175 is provided in the inflow pipe 174 that communicates with the water main main 173. The pressure sensor 175 is a pressure measuring device for measuring the pressure of the water main 173, which is the inflow pressure of the pump. Hereinafter, the “inflow pressure” shall indicate the pressure value detected by the pressure sensor 175. The detection signal from the pressure sensor 175 is input to the control unit 65 (I / O unit 70) of the water supply device. In the present embodiment, when the inflow pressure (pressure of the water main 173) becomes a certain level or less (for example, 7 mAq or less) and a predetermined time elapses, the inflow pressure is lowered. After that, when the inflow pressure becomes a certain value or more (for example, 10 mAq or more) and a predetermined time elapses, the inflow pressure decrease state is eliminated.

As the water supply method of the water supply device 10, a high water tank method may be adopted in which the water boosted by the pump is temporarily stored in a tank (high water tank) on the roof and water is supplied by natural flow. In the elevated water tank method, a water level gauge that detects the water level in the elevated water tank is provided to detect the "full state", "drought state", etc. of the elevated water tank, as described in the water receiving tank method. It is good.

[Configuration of water supply device]
Subsequently, a specific configuration of the water supply device 10 of the present embodiment will be described. FIG. 4 is a plan view schematically showing an example of the water supply device and the external display according to the present embodiment. As shown in the figure, in the water supply device 10, two pumps 30A and 30B and a pressure tank 50 arranged between the pumps 30A and 30B are mounted on the base 20. Further, the water supply device 10 includes a discharge pipe 40 connected to the discharge side of the pumps 30A and 30B, and a control panel 60 installed above the pressure tank 50. Each component will be described below.

The base 20 is a base for mounting each device such as pumps 30A and 30B on the base and fixing it to the foundation. It has a substantially rectangular flat plate shape, and both sides in the longitudinal direction are bent downward and then outside. By being bent in the direction, the L-shaped fixed sides 23, 23 are formed.

The water supply device 10 includes motors 33A and 33B for driving the pumps 30A and 30B. The pumps 30A and 30B have a suction port 35A and 35B and a discharge port. The suction ports 35A and 35B correspond to the suction port 10A of the water supply device 10, and in the case of the direct water supply system, the suction ports 35A and 35B are connected to the inflow pipe 174 via a backflow prevention device (not shown). Further, the pumps 30A and 30B are equipped with temperature sensors 36A and 36B which are temperature detectors for detecting overheating of the pump. The temperature sensors 36A and 36B and the control unit 65 of the water supply device 10 are connected by a signal line (not shown). Therefore, in order to detect the correct temperature, the signal line needs to be connected correctly.

The discharge pipe 40 is a discharge confluence pipe of the pumps 30A and 30B, and both are via a flow switch 49A and 49B, which is a kind of flow rate detector for detecting a small amount of water, and a check valve (check valve) 47A and 47B. It is connected to the discharge port of the pumps 30A and 30B. The pumps 30A and 30B can be operated in parallel. Further, the check valves 47A and 47B prevent the water in the discharge pipe 40 from flowing back to the pumps 30A and 30B when the pumps 30A and 30B are stopped. Further, the discharge pipe 40 is connected to the pressure tank 50, and a pressure sensor 48 for detecting the pressure inside the pipe is attached to the discharge pipe 40. Due to the effects of the pressure tank 50 and the check valves 47A and 47B, the pressure in the discharge pipe 40 after the pumps 30A and 30B are stopped is maintained at a constant pressure unless water is used. Hereinafter, the “discharge pressure” shall indicate the pressure value detected by the pressure sensor 48.

In this embodiment, the pumps 30A and 30B and two pumps are configured, but the number of pumps may be one or a plurality of pumps of three or more.

The control panel 60 includes a case 61, which houses a power supply terminal (not shown), an earth-leakage circuit breaker for each pump, a noise filter, an induced lightning surge absorbing element, a reactor, and the like, and further comprises a pump. It is configured to accommodate a control unit 65 (not shown in FIG. 4) composed of various electric circuits that perform operation control.

[Block configuration of control unit 65]
FIG. 5 is a block configuration diagram for explaining an example of the function of the control unit 65 of the water supply device 10 of the present embodiment. First, the control unit 65 of the water supply device 10 in the system 1000 will be described. As shown in the figure, the control unit 65 of the water supply device 10 includes a control memory (storage unit) 66, a calculation unit 69, an I / O unit (input unit and output unit) 70, an operation panel 79, and a communication unit. 73 and. The operation panel 79 includes a setting unit 71 and a display unit 72. The control unit 65 may be configured as a microcomputer that includes a CPU, a memory, and the like and realizes a predetermined function by using software, or may be configured as a hardware circuit that performs dedicated arithmetic processing. Further, the control unit 65 may be a separate board from the communication unit 73 and the operation panel 79. In that case, the control unit 65, the communication unit 73, and the operation panel 79 are connected by serial communication or wired or wireless communication such as a signal line.

The setting unit 71 is used to set various setting values (setting information) necessary for supplying water by an external operation (setting input). Specifically, the setting unit 71 includes operation buttons, a touch panel, and the like (not shown), and various setting values set in the setting unit 71 are stored in the control memory 66. As an example, the user inputs (setting input) the stop pressure, the starting pressure, the type of the signal of the external output, and other information necessary for control as setting information via the setting unit 71, and sets them at the installation site. You can change the information.

The display unit 72 functions as a user interface, and various data such as set values stored in the control memory 66 and the current operating status (operation information) of the pumps 30A and 30B, for example, the pumps 30A and 30B, respectively. The operation or stop, the operation frequency, the current, the inflow pressure, the discharge pressure, the trip of the inverter driving the motor units 33A and 33B, the suction pressure drop alarm, the water receiving tank alarm and the like are displayed.

In the present embodiment, a simple display such as a 7-segment LED and an indicator lamp can be adopted as the display unit 72. However, the display unit 72 is not limited to such an example, and may be a liquid crystal display based on a dot matrix method or the like. Further, as the external display 80, a high-performance display on a liquid crystal screen using a touch input method or a press button method can be adopted. In this case, simple information can be displayed on the display unit 72, and a large amount of information can be displayed on the external display 80. With such a configuration, the external display 80 has information on the operating status of the pumps 30A and 30B by the control unit 65 (for example, target pressure SV, current pressure PV, operation / stop of pumps 30A and 30B, and pump 30A, By displaying (such as the rotation speed of 30B) on the same screen, even a user who is unfamiliar with the water supply device can recognize the state of the water supply device 10 and change the setting without misunderstanding. Further, 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, as the display unit 72, a display composed of a 7-segment LED, an indicator lamp, a mechanical pressing button, or the like, which is more resistant to electrical noise than a liquid crystal display or a touch panel, may be used. As a result, even if an abnormality occurs in the liquid crystal display or touch panel operation of the external display 80 due to electrical noise generated from the external environment, the display unit 72 displays and operates the minimum necessary for operating the water supply device 10. It can be performed. Therefore, the water supply device 10 can be installed even in an environment with a lot of electrical noise.

The control unit 65 may not be provided with the operation panel 79 or the display unit 72, but may be provided with only the external display 80. In this case, all the functions of the operation panel 79 described above can be performed by the external display 80. Since it is not necessary to provide the water supply device 10 with the display itself, it is possible to further reduce the cost of the water supply device 10 as a whole.

The control memory 66 stores a control program for controlling the water supply device 10, device information of the water supply device 10, failure history, operation history, setting information input through the setting unit 71, and the like. Here, the output of the pump may be substituted by the capacity of the motor units 33A and 33B, the capacity of the inverter for driving the motor units 33A and 33B, and the like. Further, when a failure occurs, information such as a failure history and a periodic operation history of the water supply device 10 is also stored in the control memory 66. Further, when the wiring connection is confirmed in the test mode described later, the work history may also be stored in the control memory 66.

As the control memory 66, a ROM, HDD, EEPROM, FeRAM, a non-volatile memory such as a flash memory, and a volatile memory such as RAM are used. In the control memory 66, various data, for example, data of the calculation result in the calculation unit 69 (operating time, integrated value, etc.), pressure value (inflow pressure, discharge pressure), setting value information input through the setting unit 71, And data and the like input through the I / O unit 70 or output through the I / O unit 70 are stored.

The communication unit 73 is configured to be able to communicate with the external display 80 by wire communication or wireless communication. As the wireless communication, for example, a technique of short-range wireless communication (NFC: Near Field Communication) can be used. In addition, any method of wireless communication such as Bluetooth (registered trademark) and Wi-Fi can be used. However, NFC is advantageous in that communication can be completed only by bringing the control unit 65 and the external display 80 close to each other. Further, as for wired communication, for example, the control unit 65 may be provided with an external connection terminal such as a USB (Universal Serial Bus), and communication may be performed by connecting the external display 80 to the external connection terminal, RS422 or RS422. Serial communication such as RS232C and RS485 may be used.

A port or the like is used as the I / O unit 70. The I / O unit 70 receives a signal from the pressure sensor 48, a signal from the flow switches 49A and 49B, and the like, and the I / O unit 70 sends the input signal to the calculation unit 69. A CPU is used as the calculation unit 69. The calculation unit 69 sets various data for operating the pumps 30A and 30B based on the program and various data stored in the control memory 66 and the signal input from the I / O unit 70, and the calculation unit 69. Calculations and the like are performed, and a control command is output from the I / O unit 70.

Further, as described above, when the water supply device 10 is used in the water receiving tank system, the signal from the electrode type level switch 162 is input to the I / O unit 70, and when the water supply device 10 is used in the direct water supply system. A signal from the pressure sensor 175 is input. In addition, signals from the pressure sensor 48, the flow switches 49A, 49B, the temperature sensors 36A, 36B, etc. are input.

The I / O unit 70 and the inverter that drives the pumps 30A and 30B are connected to each other by communication means such as RS422, RS232C, and RS485. Control signals such as various set values, frequency command values, and start / stop signals (operation / stop signals) are sent from the I / O section 70 to the inverter, and the actual frequency values are sent from the inverter to the I / O section 70. The operation status (operation information) such as the current value and the current value is sequentially sent.

An analog signal and / or a digital signal can be used as the control signal transmitted / received between the I / O unit 70 and the inverters driving the pumps 30A and 30B. For example, an analog signal can be used for the rotation frequency and the like, and a digital signal can be used for the operation stop command and the like. Further, when the variable speed control of 30A and 30B is not performed, the inverter may be omitted.

Further, the I / O unit 70 has an external output terminal 70a (an example of a plurality of terminals) including at least one terminal, and the external output terminal 70a is, for example, a terminal block and a substrate constituting the control unit 65. It is implemented in. The wiring connected to the external output terminal 70a is connected to the corresponding input terminal 214a of the input unit 214 of the monitoring device 210. For example, a contact signal indicating operation-related information of the water supply device 10 is output from the external output terminal 70a. In the present embodiment, the external output terminal 70a includes five external display terminals A1, A2, B1, B2, and B3. The signals output from each of the external display terminals A1, A2, B1, B2, and B3 are set at the time of shipment of the water supply device 10 according to the requirements of each installation site.

In the system 1000, the monitoring device 210 connected to the control unit 65 includes a display unit 213 and an input unit 214, as shown in FIG. The input unit 214 has at least one input terminal (port) 214a, is connected by wire to the external output terminal 70a of the water supply device 10 by a signal line 184, and a signal from the external output terminal 70a is input. The display unit 213 displays the state of the water supply device 10 based on the information input to the input unit 214. With such a monitoring device 210, the state of the water supply device 10 can be monitored in the monitoring room 200 in which the monitoring device 210 is installed.

Here, as an example, the monitoring device 210 may have a simple configuration in which the lamp is simply turned on / off based on the signal from the external output terminal 70a of the water supply device 10. In this case, the lamp corresponds to an example of the display unit 213. Further, as an example, the monitoring device 210 may be configured as a microcomputer provided with a CPU, a memory, etc. and realize a predetermined function by using software, or may be configured as a hardware circuit for performing dedicated arithmetic processing. May be good. In such a case, the monitoring device 210 may store the history of the state of the water supply device 10 in the memory based on the input signal from the external output terminal 70a. Further, the monitoring device 210 is not limited to the one composed of a single device, and may be configured by a plurality of devices provided apart from each other as an example.

Further, the external display 80 (external terminal) connected to the control unit 65 has a display operation unit 80A, and can communicate with the communication unit 73 of the water supply device 10 to display / change various data related to the water supply device 10. It is configured as follows. Specifically, the external display 80 receives various data stored in the control memory 66 from the communication unit 73 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 73 of the water supply device 10. The display operation unit 80A can adopt 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 72 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 can display a plurality of information among various data stored in the control memory 66 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.

It should be noted that all the functions of the operation panel 79 described above may be implemented by the external display 80. This makes it easy to check the status of the water supply device 10 and change the set value information even if the water supply device 10 is installed in a place where it is difficult to operate (for example, the operation panel 79 is near the operator's feet). ..

FIG. 6 is a schematic diagram of a main part of the board on which the electronic circuit and each component in the control unit 65 are mounted. On the board of the control unit 65, the external output terminal 70a and the input terminal 70b are used as the I / O unit 70.
Various terminals (or connectors, etc.) and other various parts (not shown) such as CPU and memory are mounted. In the present embodiment, the input terminal 70b is an input terminal E11 to E15, E31 to E33 to which the signal of the electrode type level switch 162 is input, and input terminals FS1, FS2, and a pressure sensor to which the signals of the flow switches 49A and 49B are input. Includes input terminals PS1 and PS2 to which signals 48 and 175 are input. Various signal lines from the outside of the control unit 65 are wired to these terminals. Therefore, in order for these detected values to be detected correctly, it is necessary to correctly connect various signal lines.

The external output terminal 70a is a terminal block or a connector. An identification mark (AR marker) M1 for identifying the external output terminal 70a is printed on the substrate on which the terminal block is mounted. The input terminals E11 to E15 and E31 to E33 are terminal blocks, and identification marks M2 for identifying the input terminals E11 to E15 and E31 to E33 are printed on the board on which the terminal blocks are mounted. The input terminals FS1 and FS2 are connectors, and an identification mark M3 for identifying the input terminals FS1 and FS2 is printed on the board on which the connector is mounted. The input terminals PS1 and PS2 are connectors, and an identification marker M4 for identifying the input terminals PS1 and PS2 is printed on a board on which the connector is mounted.

The identification marks M1 to M4 are arranged on both sides of each terminal, and information for distinguishing each terminal from other terminals is recorded. For example, in the present embodiment, the identification mark M1 is a QR code (registered trademark) including the number of terminals, terminal names, arrangement order, etc. of the external output terminal 70a, and is arranged on both sides of the external output terminal 70a. .. Similarly, M2 to M4 are QR codes including the number of terminals, terminal names, arrangement order, etc. of the corresponding input terminals 70b, and are arranged on both sides of each input terminal 70b. As an example, the external display 80 includes an image pickup device that captures an image of the identification marks M1 to M4 and a control unit 65 including each terminal, and an image of each of the captured terminals, information acquired from the identification marks M1 to M4, and a water supply device 10. The graphic and character information based on the information obtained from the above are combined and displayed on the display operation unit 80A. That is, the external display 80 has the following steps as a display method.
(Step 1)
An imaging step for imaging any terminal of the input / output unit 70.
(Step 2)
An image composition step of synthesizing the captured image of the terminal of the input / output unit 70 with a graphic showing the terminal in the input / output unit 70 and a signal type.
(Step 3)

Further, the control unit 65 has identification marks M1 to M4 corresponding to each input terminal of the input / output unit 70 on the substrate, and in the above-mentioned imaging step, the terminal to be imaged and the identification mark M1 corresponding to the terminal are included. ~ M4 is imaged. Then, in the synthesis step, the information based on the captured identification marks M1 to M4 may be combined with the image of the input / output unit 70.
In this embodiment, the identification marks M1 to M4 are arranged on both sides of the corresponding terminals. In one embodiment, the identification marks are not limited to being placed at both ends of the corresponding terminals, but may be placed in the vicinity of the corresponding terminals so that the same image can be captured in step 1.

7A to 7D show an example of information stored in the control memory 66. FIG. 7A is information regarding the water supply system. FIG. 7B is information about each terminal of the I / O unit 70. FIG. 7C is information regarding the set value of FIG. 7B. FIG. 7D is information regarding the arrangement order of each terminal of the I / O unit 70. Hereinafter, each of the information shown in FIGS. 7A to 7D will be referred to as data tables A to D. In the present embodiment, the user can change each value of the data tables A to D by a predetermined operation on the operation panel 79 and / and the external display 80. Further, at least a part of the data tables A to D may be stored in the storage unit of the external display 80 or the identification marks M1 to M4.

The data table A shown in FIG. 7A is a diagram showing an example of the relationship between the set value of the setting code P10 and each information regarding the water supply method. In the present embodiment, as the set value information, whether it is a direct water supply method or a water receiving tank method, whether the water receiving tank is a one-tank type or a two-tank type in the water receiving tank method, or a direct water supply direct delivery type in the direct water supply method. Or, whether it is a direct water supply elevated water tank system or not is set. Specifically, when a predetermined operation is performed on the operation panel 79 and / and the external display 80 by the user, the setting code P10 which is the setting value information is changed. When the value of the setting code P10 is the value 1, the control unit 65 determines that the water receiving tank shown in FIG. 2 is used in the one-tank type water receiving tank system, and when the value of the setting code P10 is the value 3. , It is judged that it is used in the direct delivery type of the direct water supply method shown in FIG. Further, in the present embodiment, when a predetermined operation of the operation panel 79 or / and the external display 80 is performed by the user in relation to the water supply method, the number of electrode rods in the electrode type level switch 162 and the inflow of city water are performed. The control method of the valve 163 and the like are changed, and the input signals of the input terminals E11 to E15 and E31 to E33 are determined based on the set control method.

The data table B shown in FIG. 7B is an example of setting values for setting the signal type of each terminal. In the present embodiment, the set value information has a signal type of each terminal. As for the signal type, a setting code is assigned to each terminal in the I / O unit 70, and the user can set which signal is input / output from which terminal by changing the value of the setting code. .. Further, as shown in FIG. 7B, the terminal name, the terminal type, the AR marker, and the like may be stored in the data table B so that the settings can be changed. Specifically, when a predetermined operation is performed on the operation panel 79 and / and the external display 80 by the user, the terminal name, the terminal type, the AR marker, and the like can be changed. As an example, when the value of the setting code P11 which is the setting value information is changed, the type of the signal output to the terminal A1 is changed. Similarly, when the setting code P12, which is the setting value information, is changed, the type of the signal output to the terminal A2 is changed. In this way, by changing the setting code which is the setting value information, the signal type of the input / output terminal corresponding to the setting code can be changed.

The data table C shown in FIG. 7C is information showing the relationship between the set value of the value in FIG. 7B and the signal type. Specifically, in FIG. 7B, "1" is set as the setting value of the value of the setting code P11. In the value of FIG. 7C, "1" means that the signal type 1 is "operation batch", the signal type 2 is "-", and the signal type 3 is "output", so that the operation batch signal is output from the terminal A1. To. Similarly, for the other terminals, the signal type is set according to the set value of the value of the setting code corresponding to each terminal. Further, as shown in FIG. 7C, the data table C may store a plurality of signal types so that they can be changed. Further, the terminal for which the "none" value (value 0) of the signal type 1 is set does not perform input / output.

Here, an example of each output signal in signal type 1 (signal type 3 = output in FIG. 7C) will be described.
The "operation batch" signal is a signal that an ON signal is output when at least one of the pumps 30A and 30B is operating, and an OFF signal is output when both the pumps 30A and 30B are stopped.
The "failure batch" signal is a signal that an ON signal is output when some failure is detected in the water supply device 10, and an OFF signal is output when a failure is not detected in the water supply device 10.
For each of the "full", "reduced", and "drought" signals, an ON signal is output when the water receiving tank 160 is in a full, low, or dry state when the water supply system is a water receiving tank system, and the water is full. It is a signal to which an OFF signal is output when it is not in a state, a low water state, or a drought state.
For each of the signals of "No. 1 pump operation" and "No. 1 pump failure", an ON signal is output and stopped when the pump 30A is operating or a failure is detected. This is a signal to which an OFF signal is output when a failure is not detected.
For each of the signals of "No. 2 pump operation" and "No. 2 pump failure", an ON signal is output and stopped when the pump 30B is operating or a failure is detected. This is a signal to which an OFF signal is output when a failure is not detected.
The "inflow pressure drop" signal is an ON signal when the inflow pressure measured by the pressure sensor 175 is lower than a predetermined threshold value for a predetermined time when the water supply method is a direct water supply method. It is a signal to which an OFF signal is output when it is output and the inflow pressure is not in a lowered state, or when a state in which the inflow pressure is restored to a predetermined pressure or higher continues for a predetermined time.
For each of the "full" and "drought" signals of the elevated water tank, when the water supply method is the elevated water tank method, an ON signal is output when the elevated water tank (not shown) is full or drought, and the signal is high. This is a signal to which an OFF signal is output when the water tank is not full or drought.
Further, an example of each input signal (signal type 3 = input) in the signal type 1 is shown below.
The signals of the flow switches 49A and 49B are input to the terminals set to the "flow switch 1" and "flow switch 2".
The signals of the pressure sensors 48 and 175 are input to the terminals set in the "pressure sensor 1" and "pressure sensor 2".
The signals of the temperature sensors 36A and 36B are input to the terminals set in the "temperature sensor 1" and "temperature sensor 2".
When the water supply method is the receiving tank method, the signal of the electrode rod 162e of the full water level and the water level of the low water level are set to the terminals set to "full water level", "low water level", "dry water level", and "dry water level". The signal of the electrode rod 162d, the signal of the electrode rod 162c of the drought recovery water level, and the signal of the electrode rod 162b of the drought water level are input.

The data table D shown in FIG. 7D shows an example of information on the arrangement order of each terminal. For example, FIG. 7D stores the arrangement order of the external output terminals 70a. In addition, various terminals such as input terminals E11 to E15, E31 to E33, input terminals FS1, FS2, input terminals PS1 and PS2 may also store the arrangement order in the same manner.

[Water supply control by water supply device 10]
An example of water supply control of the water supply device 10 by the control unit 65 will be described. When the discharge pressure drops to a predetermined starting pressure while the pumps 30A and 30B are stopped, the control unit 65 starts at least one of the pumps 30A and 30B. Specifically, the control unit 65 issues a command to the motor units 33A and 33B (inverter if provided) to start driving the pumps 30A and 30B. During the operation of the pumps 30A and 30B, control such as estimated terminal pressure constant control or target pressure constant control is performed by the set pressure (set pressure). Specifically, in the case of constant estimated terminal pressure control, the target pressure (SV) for the discharge pressure of the pumps 30A and 30B is set by using the rotation speed of the pumps 30A and 30B and the target pressure control curve, and the target pressure is constant. In the case of control, the set pressure is set as the target pressure (SV). Further, the discharge pressure is set to the current pressure (PV). Then, a PI calculation or a PID calculation is performed based on the deviation between the SV and the PV, and the command rotation speeds of the pumps 30A and 30B are set. When the estimated terminal pressure is constantly controlled by the direct water supply, the target pressure control curve may be corrected based on the inflow pressure. Specifically, the target pressure (SV) is calculated by adding only the inflow pressure to the target pressure control curve. Further, when there are a plurality of pumps as in the present embodiment, the control unit 65 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).

When the amount of water used in the building is reduced during the operation of the pumps 30A and 30B, the flow switches 49A and 49B detect the insufficient amount of water and send the detection signal to the control unit 65. Upon receiving this detection signal, the control unit 65 issues a command to the pumps 30A and 30B to operate the pumps 30A and 30B at a predetermined rotation speed. Then, when the control unit 65 determines that the discharge pressure reaches a predetermined operation stop pressure and accumulates the pressure in the pressure tank 50, the pumps 30A and 30B are stopped (small amount of water is stopped). When water is used again in the building after the pumps 30A and 30B are stopped by a small amount of water, the discharge pressure drops to the starting pressure or less and the pumps 30A and 30B are started. When there are a plurality of pumps as in the present embodiment, it is preferable to rotate the starting pumps 30A and 30B to prevent water from staying in the pumps 30A and 30B. Further, as a method for detecting the small amount of water, other means such as a low load due to the current value of the motor units 33A and 33B and the cutoff pressure may be used without using the flow switches 49A and 49B.

Further, in the present embodiment, the control unit 65 determines the water supply method or the like by referring to the information stored in the control memory 66, for example, various information of FIGS. 7A to 7D. In particular, in the case of the water receiving tank system, the water receiving tank control is executed by determining information such as the number of water receiving tanks and the number of electrodes of the electrode type level switch 162. Specifically, the control unit 65 determines that the water receiving tank is a one-tank type and the number of electrode rods is five, and when the electrode rods connected to the input terminal E14 are exposed from the water surface, the water level of the water receiving tank 160 is reached. It is judged that the water level has become lower than the drought water level, and the water level state is set as the drought state. In a drought state, the control unit 65 forcibly stops the pumps 30A and 30B and issues a drought warning. Both the forced stop of the pumps 30A and 30B and the drought alarm are canceled. Further, the control unit 65 determines that the water level of the water receiving tank 160 has become higher than the full water level when a part of the electrode rod connected to the input terminal E11 is submerged, and sets the water level to a full water level. Issue an alarm. Further, when the electrode rod connected to the input terminal E12 is exposed from the water surface, the control unit 65 determines that the water level of the water receiving tank 160 has become lower than the reduced water level, sets the water level state to the reduced water level, and issues a water reduction alarm. After that, when a part of the electrode rod connected to the input terminal E1 is submerged, it is determined that the water level is equal to or higher than the water level for returning to the water level, and the water level is reduced and the water level alarm is canceled. The control unit 65 sets the water level state to the normal state when none of the full state, the low water state, and the drought state has occurred.

[I / O signal display method and test method for input / output section]
Next, the input / output signal display method and test method of the input / output unit (I / O unit) 70 are described by checking the output signal of the external output terminal 70a in the system 1000 and wiring the external output terminal 70a and the monitoring device 210. This will be explained together with the method for checking the connection. In the following description, as an example, the display is performed by the display operation unit 80A of the external display 80. However, such a display may be made by the display unit 72 of the control unit 65 in place of or in addition to the display operation unit 80A. In that case, the operation panel 79 has the same configuration and function as the external display 80. In other words, the display method described below may be executed by the control unit 65 of the water supply device 10 or by the external display 80 capable of acquiring information from the control unit 65 of the water supply device 10. .. Further, the display method is not limited to the one executed by a single device, and may be executed by combining the functions of a plurality of devices.

FIG. 8 is a flowchart showing an example of processing executed by the external display 80. This process is performed when the user operates the external display 80 to instruct the status display of the input / output unit of the water supply device 10 in a state where communication between the external display 80 and the water supply device 10 shown in FIG. 1 is established. Is executed.

When the process is started, the external display 80 acquires the setting of the I / O unit 70 (step S102). The process of step S102 by the external display 80 is performed by receiving information from the water supply device 10. In the present embodiment, the external display 80 is input / output to and from each of the information related to the arrangement of the plurality of terminals (external output terminal 70a and the input terminal 70b) in the I / O unit 70 and the plurality of terminals by communication. Get the type of signal. Specifically, the external display 80 is set to access the data tables A to D of the control memory 66 of the control unit 65 via the communication unit 73 and indicate the type of the signal output from the external output terminal 70a. By acquiring the setting value of the code and the like, the information related to the arrangement of the plurality of terminals and the type of the signal in the plurality of terminals may be acquired. Since the settings of the input / output unit I / O unit 70 are not changed frequently after being set once, the external display 80 sets the settings related to the I / O unit 70 from the water supply device 10 only once. It may be received and stored in a storage unit (not shown), and thereafter, the setting of the I / O unit 70 may be acquired by referring to its own storage unit.

Subsequently, the external display 80 acquires various states related to the signals input / output to / from the I / O unit 70 (step S104). The process of step S104 may be performed based on the setting of the I / O unit 70. For example, in the setting of the external output terminal 70a (for example, setting codes P11 to P15), any signal of the water level state (for example, any of the values 3 to 5) is set in any of the external display terminals. If so, the external display 80 accesses the control memory 66 of the control unit 65 by communication to acquire the water level state (full state, low water state, drought state, etc.). Further, when the state of the water supply device 10 (for example, one of the values 1 and 2) such as pump operation or failure is set in any of the external display terminals in the setting of the external output terminal 70a, the external display is performed. The device 80 accesses the control memory 66 of the control unit 65 via the communication unit 73 to acquire the state of the water supply device 10. Further, as an embodiment, in step S104, the external display 80 may acquire all the related states of the water supply device 10 regardless of the setting of the I / O unit 70.

Next, the external display 80 displays a terminal graphic showing a plurality of terminals in the I / O unit 70 and the types of signals input / output by the terminals together (step S106). The external display 80 creates a terminal graphic to be displayed based on various information acquired in step S102. Specifically, the terminal graphic is created based on the information in the data table D of the control memory 66, and the signal type is drawn based on the information in the data table B. Here, the graphic display of the external output terminal 70a includes graphic display of identification information for identifying each external output terminal 70a.

FIG. 9A is a diagram showing a graphic display of the type of the signal output from the external output terminal 70a and the external output terminal 70a according to the first example in the external display 80. In FIG. 9A, it can be used when the water supply system is a water receiving tank system. Specifically, FIG. 9A is an example of the screen of the external display 80 displayed in step S106 when the setting code P10 acquired in step S102 has a value of 1. In the example shown in FIG. 9A, outputs are output from each of the terminal graphic unit 802 that graphically displays the external output terminal 70a, the wiring diagram graphic unit 806 that shows the continuity in the water supply device 10 at the external output terminal 70a by wiring, and the external output terminal 70a. The signal type character information unit 808 indicating the type of the signal to be output in character information is displayed on the display operation unit 80A of the external display 80. The signal type character information unit 808 may be displayed, for example, based on the information in the data table B acquired in step 102 and based on each value in the data table C.

Specifically, in the terminal graphic unit 802, as a graphic display of the external output terminal 70a, the common terminals of the external display terminals A1 and A2 and the external display terminals A1 and A2 are the same as the arrangement of the data table D in FIG. The ACM, the external display terminals B1, B2, B3, and the common terminal BCM of the external display terminals B1, B2, B3 are displayed side by side. The terminal graphic unit 802 may be graphically displayed in an arrangement that matches or corresponds to the arrangement of the external display terminals A1, A2, B1, B2, B3, ACM, and BCM in the actual water supply device 10. That is, the terminal graphic unit 802 is created based on the arrangement of a plurality of terminals in the I / O unit 70. Further, the arrangement order of the terminals may be a fixed value stored in the external display 80 and / and the control unit 65 as device information instead of the setting information. Further, in the example shown in FIG. 9A, an "external display terminal" and a terminal type character information unit 804 indicated by character information are displayed next to the terminal graphic unit 802. The terminal type character information unit 804 may be displayed, for example, based on each value of the terminal type of the data table B acquired in step 102. This makes it easier for the user to understand that the display of the terminal graphic unit 802 indicates the external display terminal.

In the example shown in FIG. 9A, the terminal graphic unit 802 graphically displays the external output terminal 70a using figures and characters, but the present invention is not limited to such an example, and for example, the external output terminal of the actual water supply device 10 is displayed. The external output terminal 70a may be graphically displayed using the image of 70a. Further, the external display 80 may graphicly display the external output terminal 70a by using augmented reality (AR). Specifically, in the control unit 65 of the present embodiment, the identification mark M1 for identifying the external output terminal 70a is printed on the substrate on which the external output terminal 70a is mounted. By arranging the identification mark M1 on the side of the external output terminal 70a, the imaged external display 80 can identify the arrangement order and size of the external output terminal 70a. The external display 80 further includes an image pickup device for capturing an image of the control unit 65 including the identification mark M1 and the external output terminal 70a, the image of the captured external output terminal 70a, the information acquired from the identification mark M1, and the water supply device. The connection diagram graphic unit 806 based on the information acquired from 10 and the signal type character information unit 808 are combined and displayed on the display operation unit 80A.

FIG. 9B is an example of a display state transition diagram. As shown in FIG. 9B, in the external display 80, when the AR display button 810 (display selection means) provided in the display operation unit 80A is pressed (arrow: S130), the external output terminal 70a uses augmented reality. Graphic display is performed, and when the AR release button 812 (display selection means) provided on the display operation unit 80A is pressed (arrow: S131), the display by augmented reality is canceled and the terminal graphic unit 802 of the figure imitating the terminal is used. The external output terminal 70a may be displayed graphically. In other words, as a display method in the external display 80, the external display 80 has a first state and a second state for displaying a terminal graphic indicating a plurality of terminals in the input / output unit and a signal type. In the first state, a terminal graphic (terminal graphic unit 802) that imitates a plurality of terminals in the input / output unit 70 using a graphic, and a type of signal input / output to / from each terminal (terminal type character information unit 804, connection diagram). The graphic unit 806 and the signal type character information unit 808) are displayed together, and in the second state, the display using the augmented reality (that is, the display of the image synthesized in the following image synthesis step) is performed. As a result, the user can select a display method according to the installation environment of the water supply device 10, the performance of the image processing of the external display 80, and the like. In particular, the installation location of the water supply device 10 may be a pump room or a dark narrow area between buildings, or the work may be performed in an environment unsuitable for imaging or image display, such as being exposed to direct sunlight outdoors. However, since the display method can be selected in the present embodiment, the operator can select a display suitable for the installation environment.

Further, when the external output terminal 70a is graphically displayed using augmented reality, characters for identifying the external output terminal 70a such as "A1", "A2", "B1", "B2", and "B3" are used. It is preferable that the information is shown together with the image of the external output terminal 70a captured by at least one of the connection diagram graphic unit 806 and the signal type character information unit 808.

As shown in FIG. 9C, the external display 80 has the following steps as a display method using augmented reality (AR).
(Step 141)
An imaging step for imaging any terminal of the input / output unit 70. At this time, the identification marks (AR markers) M1 to M4 corresponding to the input / output unit to be imaged are also imaged.
(Step 142)
In the captured image of the terminal of the input / output unit 70, a graphic showing a plurality of terminals in the input / output unit 70 (terminal graphic unit 802) and a signal type (terminal type character information unit 804, connection diagram graphic unit 806, An image composition step for synthesizing the signal type character information unit 808).
Specifically, the captured image of each terminal of the input / output unit 70 and each terminal of the terminal graphic unit 802 are combined so as to overlap each other, and next to the combined terminal graphic unit 802, there is a terminal type character information unit. At least one of 804, the connection diagram graphic unit 806, and the signal type character information unit 808 is combined so as to be displayed. Further, in this step, it is preferable that the highlighting unit 849, which will be described later, is also synthesized.
(Step 143)
A display step for displaying the combined image of the input / output unit.

Since the control unit 65 has the identification marks M1 to M4 corresponding to the input terminals of the input / output unit 70 on the same substrate as the input / output unit 70, in the above-mentioned imaging step, the terminal to be imaged corresponds to the terminal. The identification marks M1 to M4 can be imaged at the same time. Then, in the synthesis step, the information based on the captured identification marks M1 to M4 is combined with the image of the input / output unit 70. In this embodiment, the identification marks M1 to M4 are arranged on both sides of the corresponding terminals as shown in FIG. This facilitates simultaneous imaging of the terminal to be imaged and the identification marks M1 to M4 corresponding to the terminal. In one embodiment, the identification mark is not limited to being placed at both ends of the corresponding terminal, but may be placed in the vicinity of the corresponding terminal so that the same image can be captured in step 141.

The wiring diagram graphic unit 806 graphically displays a wiring diagram showing a connection state due to continuity between the external output terminal 70a and the water supply device 10. Specifically, in the first example shown in FIG. 9A, as the connection diagram graphic unit 806, the external display terminals A1 and A2 indicate an ON / OFF signal as to whether or not they are electrically connected to the common terminal ACM, and are externally displayed. Terminals B1, B2, and B3 indicate ON / OFF signals for whether or not to conduct with the common terminal BCM. For example, the connection diagram graphic unit 806 may create a graphic imitating the electric circuit of each terminal based on each value of the common of the data table B acquired in step 102, and display the created graphic. ..

The signal type character information unit 808 is displayed adjacent to the terminal graphic unit 802. Specifically, in the example shown in FIG. 9, the set value of each "value" of P11 to P15 of the data table B acquired in step 102 and the signal type 1 of the data table C corresponding to the set value are set. Based on this, the signal of "operation batch" is output from the external display terminal A1, the signal of "failure batch" is output from the external display terminal A2, and the signal of "full water" is output from the external display terminal B1. It is shown that the signal of "water reduction" is output from the external display terminal B2, and the signal of "drainage" is output from the external display terminal B3. In this way, the terminal graphic unit 802 is displayed in an arrangement that matches or corresponds to the arrangement of the external display terminals A1, A2, ACM, B1, B2, B3, and BCM in the actual water supply device 10, and the terminals are displayed. By displaying the type of the signal output from the external output terminal 70a adjacent to the graphic unit 802, the user can perform wiring work and wiring between the external output terminal 70a of the water supply device 10 and the monitoring device 210. You can easily check the connection.

The external display unit 80 highlights the signal type corresponding to the external output terminal 70a currently in the ON state in at least one of the terminal graphic unit 802, the connection diagram graphic unit 806, and the signal type character information unit 808. Highlight. The highlighting unit 849, which means an ON signal, may be displayed, for example, based on the value acquired in step 104. Specifically, here, in the control unit 65, since the terminal of A1 outputs an ON signal, the characters "operation batch" are highlighted with a thick frame line. Thereby, the user can easily understand that the external display terminal A1 outputs the ON signal by looking at the external display 80. In highlighting, instead of or in addition to the thick frame of the highlighting unit 849, it suffices to distinguish it from the terminal in the OFF state by lighting or blinking, font or character size, display color, and the like. The highlighting unit 849 graphically displays the external output terminal 70a that is currently ON and the external output terminal 70a that is currently OFF, and graphically displays the state of the signal output by the external output terminal 70a. This is an example of "input / output information display". In this embodiment, it should be noted that
The signal type corresponding to the external output terminal 70a currently in the ON state is highlighted. However, the present invention is not limited to such an example, and the external display 80 may highlight the signal type corresponding to the place where a predetermined signal (for example, an ON signal) is input / output in the input / output unit 70. ..

The name used in the signal type of the external output terminal 70a displayed on the external display 80 may be stored as set value information in the control memory 66 and / or the external display 80, or may be stored in the device. It may be stored as a fixed value as information. However, as shown in FIG. 7C as an example, when the set value information is stored, the display can be easily changed.

FIG. 9D is a diagram showing a graphic display of the external output terminal 70a and the input terminal 70b displayed on the external display 80 and the types of signals input / output to the external output terminal 70a and the input terminal 70b. The display of FIG. 9D corresponds to a modified example of the display of FIG. 9A, and is an example of being displayed when the water supply system is the water receiving tank system as in FIG. 9A. In FIG. 9D, the description overlapping with FIG. 9A will be omitted. In addition to the external output terminal 70a, the display shown in FIG. 9D shows a terminal graphic showing the input terminals 70b (terminals E11 to 15, E31 to E33) and a type of signal input to the input terminal 70b. Here, in the example shown in FIG. 9D, the types of input signals to the terminals E11 to E15 in the input terminal 70b are a water level gauge graphic unit 836 imitating a plurality of electrode rods 162a to 162e of the water level gauge, and a plurality of water level gauges. The control for the detection of the electrode rods 162a to 162e is indicated by the control character information unit 838 which indicates the control for the detection of the electrode rods 162a to 162e.

In the example shown in FIG. 9D, the signals output from the terminals B1 to B3 are "full", "reduced water", and "drought" in the water receiving tank, and are output based on the signals input to the terminals E11 to E15. Then, in the example shown in FIG. 9D, for the input terminals E11 to E15 related to the signals output from the terminals B1 to B3, the terminal graphic indicating the input terminals E11 to E15 and the type of the signal are displayed together. Specifically, in the example shown in FIG. 9D, as an example, the output display unit 80A1 including the terminal graphic of the external output terminal 70a and the signal type is displayed above, and the input terminal 70b related to the output signal of the external output terminal 70a is displayed. The input display unit 80A2 including the terminal graphic and the signal type of is displayed at the bottom. The relationship between the external output terminal 70a and the input terminal 70b may be determined, for example, based on the information in "Signal type 2" of the data table C (FIG. 7C). That is, for example, the external display 80 is based on the "signal type 2" of the value 1 in the data table C when the setting code P11 of the data table B (FIG. 7B) acquired from the water supply device 10 is the "value 1". Therefore, it is preferable to display the information regarding the input terminal 70b in which the related "value 201" and "value 202" are set on the display operation unit 80A. With such a display, the user who sees the external display 80 can better understand the signal input / output to / from the I / O unit 70.

The display on the output display unit 80A1 is substantially the same as the display on FIG. 9A. However, in FIG. 9D, unlike FIG. 9A, an OFF signal is output from the terminal A1 and an ON signal is output from the terminal B1. Therefore, the highlighting unit 849 highlights the information about the terminal B1. Further, in the example shown in FIG. 9A, the history save button 813 is further provided on the operation display unit 80A. By selecting the history save button 813, the user can save the displayed input / output signal of the I / O unit as the input / output signal history. The input / output signal history may be stored in a storage unit (not shown) of the external display 80, or may be stored in the control memory 66 of the water supply device 10.

The display on the input display unit 80A2 is an input terminal graphic unit 835 indicating terminals E11 to E15 and E31 to E33 of the input terminal 70b, and a water level gauge graphic displaying a water level gauge graphic imitating a plurality of electrode rods 162a to 162e of the water level gauge. Section 836, input terminal connection diagram showing input terminal connection that imitates the connection diagram between the plurality of electrode rods 162a to 162e of the water level gauge and the input terminal 70b Control of the detection of the plurality of electrode rods 162a to 162e of the water level gauge Has a control character information unit 838 that indicates the above in character information. In the example shown in FIG. 9D, as the state of the input signal of the input terminal 70b, the character information unit 844 indicating that all the terminals E12 to E15 are short-circuited with respect to the common terminal E11 is displayed, and the character information unit 844 is displayed. The short-circuited terminals E12 to E15 (and / or terminal E11) in the input terminal graphic unit 835 are highlighted. Further, in the example shown in FIG. 9D, the display on the input display unit 80A2 is a water level graphic unit 843 that imitates the water level of the water receiving tank 160 as information indicating the state of the system 1000 based on the signal input to the input terminal 70b. It has a highlighting unit 842 that emphasizes the current state of the control character information unit 838.

FIG. 10 is a diagram showing a graphic display of the type of the signal output from the external output terminal 70a and the external output terminal 70a according to the second example in the external display 80 displayed in step S106 of FIG. .. The display shown in FIG. 10 can be used when the water supply system is an elevated water tank system. Specifically, FIG. 10 is an example of the display of step S106 when the setting code P10 acquired in step S102 has a value of 4. The display shown in FIG. 10 is different from the character information displayed in the signal type character information unit 808, and is the same as the display shown in FIG. 9A in other points. That is, in the example shown in FIG. 10, the terminal graphic unit 802, the terminal type character information unit 804, and the connection diagram graphic unit 806 are displayed on the display operation unit 80A. In the following, the AR display button 810, the AR release button 812, and the description of each function, which overlap with FIG. 9, will be omitted.

In the example shown in FIG. 10, the types of signals output from the external display terminals B1, B2, and B3 are different from the example shown in FIG. This is because the type of signal output from each external display terminal can be changed. Specifically, the external display 80 accesses the data tables A to D via the communication unit 73 in step S102 shown in FIG. 8, and indicates the type of the signal output from the external output terminal 70a. Acquire the setting value of the setting code (P11 to P15). Since the values set in the data table B are different between the first example and the second example, the character information displayed in the signal type character information unit 808 is different. Specifically, in the data table B of the second example, each "value" of P11 to P15 has "operation batch", "failure batch", "inflow pressure drop", "full water" of the elevated water tank, and high. A value corresponding to the "drought" of the water tank is set, and based on the acquired information, the external display 80 outputs a signal of "operation batch" from the external display terminal A1 and outputs the signal of "operation batch" to the external display terminal A2. "Failure batch" signal is output from, "Inflow pressure drop" signal is output from the external display terminal B1, and "Full water" signal of the elevated water tank is output from the external display terminal B2 for external display. It is determined that the signal of "drought" of the elevated water tank is output from the terminal B3, and the signal type character information unit 808 is created. As a result, as shown in FIG. 10, the signal type character information unit 808, together with the terminal graphic unit 802, sets the signal types of the external display terminals A1, A2, B1, B2, and B3 as "operation batch" and "failure batch". "Inflow pressure decrease" "Full water in the elevated water tank" "Drunk water in the elevated water tank" is shown. In step S104 shown in FIG. 8, the external display 80 accesses the control unit 65 via the communication unit 73, and receives an ON signal or an OFF signal output from each external display terminal of the external output terminal 70a. The state is acquired, and the state is identifiablely displayed on the connection diagram graphic unit 806 and / and the signal type character information unit 808.

FIG. 11 is a diagram showing a graphic display of the external output terminal 70a according to the third example of the external display 80 and the type of the signal output from the external output terminal 70a. The display shown in FIG. 11 can be used when the water supply system is a direct water supply system. The display shown in FIG. 11 is different from the display shown in FIG. 9 in that the information displayed in the signal type character information unit 808 is the same in other respects. That is, in the example shown in FIG. 11, the terminal graphic unit 802, the terminal type character information unit 804, and the connection diagram graphic unit 806 are displayed on the display operation unit 80A. In the following, the AR display button 810 and the AR release button 812 that overlap with FIG. 9 and the description of each function will be omitted.

In the example shown in FIG. 11, the types of signals output from the external display terminals A1, A2, B1, B2, and B3 are different from the example shown in FIG. Specifically, the external display 80 accesses the data table A via the communication unit 73 in step S102 shown in FIG. 8, and is a setting code indicating the type of the signal output from the external output terminal 70a. Acquire the set values of (P11 to P15). Since the values set in the data table B are different between the first example and the second example, the character information displayed in the signal type character information unit 808 is different. Specifically, in the data table B of the third example, the "values" of P11 to P15 include "No. 1 pump operation signal", "No. 1 pump failure signal", and "No. 2 pump failure signal". Values corresponding to "operation signal", "No. 2 pump failure signal", and "inflow pressure drop" are set, and the external display 80 is set to "No." from the external display terminal A1 based on the acquired information. .1 "Pump operation signal" is output, "No. 1 pump failure signal" is output from the external display terminal A2, and "No. 2 pump operation signal" is output from the external display terminal B1. It is determined that the "No. 2 pump stop signal" is output from the display terminal B2 and the "inflow pressure decrease signal" is output from the external display terminal B3, and the signal type character information unit 808 is created. As a result, as shown in FIG. 11, the signal type character information unit 808, together with the terminal graphic unit 802, has the signal type of the external display terminals A1, A2, B1, B2, and B3 as "No. 1 pump. Character information such as "operation signal", "No. 1 pump failure signal", "No. 2 pump operation signal", "No. 2 pump stop signal", and "inflow pressure decrease signal" is shown. In step S104 shown in FIG. 8, the external display 80 accesses the control unit 65 via the communication unit 73, and receives an ON signal or an OFF signal output from each external display terminal of the external output terminal 70a. The state is acquired, and the state is identifiablely displayed on the connection diagram graphic unit 806 and / and the signal type character information unit 808.

Here, as described above, in the pump equipment, the detection target of the output signal (for example, the water receiving tank 160) and the connection destination of the water supply device 10 and the external output terminal 70a (monitoring device 210) are on different floors, outdoors and indoors. , Or may be installed in a remote location, such as in a different building. In particular, in such a case, a plurality of workers check the connection between the signal detection target (water receiving tank 160), each terminal of the water supply device 10 and the external output terminal 70a of the water supply device 10, and the connection destination (monitoring device 210). It becomes a complicated work such as checking each other's status in cooperation with each other. In order to facilitate such a connection confirmation work, in this embodiment, a signal output test using a pseudo signal (step S110 in FIG. 8) is executed as shown below.

In the example shown in FIGS. 9, 10 and 11 described above, the external display 80 displays a test button 809 for starting a signal output test. The test button 809 is a means for switching to the test mode, and when the user selects the test button 809, the test of the external output in step S109 or less in FIG. 8 is started. Further, when the test button is selected, the external display 80 transmits a signal for switching the water supply device 10 to the test mode. Further, the external display 80 repeats steps S104 to S108 until the test button 809 to which the user inputs the switching to the test mode is pressed in step S108 (FIG. 8: step S108: No).

See FIG. 8 again. In FIGS. 9, 10, and 11 described above, the external display 80 transmits a test mode command to the control unit 65 when the test button 809 is selected by the user (step S108: Yes) (step S109). The selection of the test button 809 by the user corresponds to an example of accepting a switching instruction for switching the water supply device 10 to the test mode. Then, a display (test display) for a connection test of at least one of the external display terminals A1, A2, B1, B2, and B3 in the external output terminal 70a is executed (step S110).

FIG. 12 is a diagram showing a display by the external display 80 for testing the connection state between the external output terminal 70a of the water supply device 10 and the monitoring device 210 according to the first example. FIG. 12 is an example of the display in step S110 when the test button 809 of FIG. 9A is selected, and the type of information output from the external output terminal 70a is the same as the example shown in FIG. An example of the display when the user tests the connection state between the electrode type level switch 162 and the input terminal E11 and the connection state between the external display terminal B1 and the monitoring device 210 is shown.

In the example shown in FIG. 12, the terminal graphic showing the external output terminal 70a and the type of the signal output from the external output terminal 70a are displayed in the area 80C below the display operation unit 80A as in FIG. There is. Specifically, in the example shown in FIG. 12, the display operation unit 80A has a terminal graphic unit 802, a terminal type character information unit 804, a wiring diagram graphic unit 806, and a signal type character information unit 808, and is shown in FIG. The signal type is determined and displayed based on the value of the setting code (P11 to P15) indicating the signal type of the external output terminal 70a acquired in step S102 shown in 1. In the example shown in FIG. 12, the AR display button and the AR release button for the external output terminal 70a are not shown, but the AR display button and the AR release button for the external output terminal 70a are similar to those in FIG. It may be provided.

In the example shown in FIG. 12, in the signal type character information unit 808, the signal type corresponding to the external output terminal 70a for which the connection test is performed is highlighted by being surrounded by a thick frame which is an example of the highlighting unit 849. .. Specifically, here, the external display 80 determines that the external output to be tested is a full water signal output from the external display terminal B1 and highlights the characters "full". This allows the user to easily understand that the external display terminal 80 is being viewed and the connection test of the external display terminal B1 and the "full" signal is being performed. The highlighting unit 849 highlights the terminal graphic unit 802 corresponding to the external output terminal 70a for which the connection test is performed, in place of or in addition to the signal type character information unit 808 corresponding to the external output terminal 70a for which the connection test is performed. It may be displayed. In highlighting, instead of or in addition to the thick frame of the highlighting unit 849, it is sufficient to distinguish it from other terminals or signal types by lighting or blinking, font or character size, display color, and the like.

In the example shown in FIG. 12, a method for outputting an ON signal or an OFF signal from the external output terminal 70a for performing a connection test is displayed in the area 80B above the display operation unit 80A. In this way, the screen of the display operation unit 80A is divided into the area 80B and the area 80C, the connection test method is displayed in the area 80B, and the output signal from the external output terminal 70a is displayed in the area 80C. That is, the state of the pump device related to the output method is displayed together with the output method for outputting the test signal. This allows the user to easily see which terminal is being tested. In this embodiment, the connection test method is displayed in the upper region 80B of the display operation unit 80A, and the output signal from the external output terminal 70a is displayed in the lower region 80C. In one embodiment, the output signal from the external output terminal 70a may be displayed in the upper region 80B of the display operation unit 80A, and the connection test method may be displayed in the lower region 80C. Further, the method of dividing the screen does not depend on the top and bottom, and may be divided into left and right, for example.

In the example shown in FIG. 12, it is shown that the terminal E11 and the terminal E15 of the water supply device 10 are short-circuited as a method of changing the full water signal from the OFF signal to the ON signal as a test signal. Here, the external display 80 may acquire a method for outputting a test signal from the external output terminal 70a for performing a connection test by communication from the water supply device 10 in steps S102 or S104. Further, the external display 80 is tested from the external output terminal 70a in order to perform the connection test according to a predetermined relationship based on the signal type of the terminal to be connected and the various settings related to the external output. A method for outputting a signal may be derived. That is, for example, the target of the connection test (“full water signal” in the example shown in FIG. 12) and the set value set in the “value” of the setting code P20 (value “201” in the examples shown in FIGS. 7C and 7C). A method of outputting an ON signal from the external display terminal B1 in order to perform a connection test based on a predetermined relationship (“full water level”) (in the example shown in FIG. 12, the terminal E11 and the terminal E15 are connected. (Short circuit) may be derived and displayed graphically on the display operation unit 80A.

In the example shown in FIG. 12, the test target character information unit 831 indicating the type of information of the external output signal to be subjected to the connection test in character information, the setting code character information unit 832 indicating the setting code in character information, and the output for outputting the test signal. A test method character information unit 833 indicating the method in character information is displayed. Specifically, the character information unit 831 for the test displays "external output test: full water" to indicate to the user that the external output signal for which the connection test is performed is a full water signal. The setting code character information unit 832 displays "liquid level input terminal (setting = 2)" and sets the city water inflow method of the water supply device, the number of water tanks connected to the water supply device, the water supply source, and the like. It indicates to the user that the setting value of the setting is the value "2". Further, the test method character information unit 833 displays "E11-E15 short circuit" to indicate to the user that the terminal E11 and the terminal 15 or the electrode rods 162a and 162e are connected and short-circuited.

Further, in the example shown in FIG. 12, in addition to the test method character information unit 833, an input terminal graphic imitating the terminals E11 to E15 and E31 to E33 of the input terminal 70b is displayed as a graphic display of the test signal output method. Input terminal graphic unit 835, water level gauge graphic unit 836 that displays water level gauge graphics imitating multiple electrode rods 162a to 162e of the water level gauge, connection diagram of the plurality of electrode rods 162a to 162e of the water level gauge and the input terminal 70b. The test method is graphicized by the input terminal connection diagram unit 837 showing the imitated input terminal connection, the control character information unit 838 indicating the control for the detection of the plurality of electrode rods 162a to 162e of the water level gauge by character information, and the input terminal graphic unit 835. It has a test method graphic unit 834 shown by (in this embodiment, an arrow indicating that the terminal E11 and the terminal E15 are short-circuited). Here, the input terminal graphic unit 835 may be graphically displayed in an arrangement that matches or corresponds to the arrangement of the terminals E11 to E15 and E31 to E33 of the input terminal 70b of the actual water supply device 10. In the input terminal graphic unit 835, the water level gauge graphic unit 836, the input terminal connection diagram unit 837, and the control character information unit 838, the graphic corresponding to the set value of the setting code P10 is displayed in advance in the control memory 66 or the external display of the water supply device 10. It is preferable that the information is stored in a storage unit (not shown) of the device 80 and displayed on the display operation unit 80A using the stored information. In this way, since the external display 80 displays the method of outputting the test signal, the user who operates the external display 80 can easily see each electrode of the electrode type level switch 162 while looking at the external display 80. The connection between the rod and the water supply device 10 and / and the water supply device 10 and the monitoring device 210 can be confirmed.

Further, in the example shown in FIG. 12, figures and characters imitating the respective terminals of the input terminals 70b (terminals E11 to E15, E31 to E33) are displayed, but the present invention is not limited to these examples, and for example, actual water supply. The image of the input terminal 70b of the device may be used for display. For example, the external display 80 may display a method for performing a connection test by using augmented reality. Specifically, the control unit 65 has identification marks M2 to M4 printed on the substrate on which the external output terminal 70a is mounted to identify the input terminal 70b. By arranging the identification marks M2 to M4 on both sides of the input terminal 70b, for example, the external display 80 can identify the arrangement order and size of the input terminals 70b by the captured image and the identification marks M2 to M4. .. The external display 80 further includes an image pickup device that captures an image of the control unit 65 including the identification markers M2 to M4 and the input terminal 70b, and similarly to FIG. 8C, the image acquired from the image of the input terminal 70b and the information acquired from the identification label. Based on the information acquired from the water supply device 10 in step S102, the image of the input terminal 70b and the input terminal graphic unit 835 can be superimposed and displayed. Similar to FIG. 8B, the external display 80 displays using augmented reality when the AR display button 839 provided on the display operation unit 80A is pressed, and the AR release button 840 provided on the display operation unit 80A displays. When pressed, the display by augmented reality is canceled. Further, when displaying using the augmented reality, the image of the input terminal 70b, the test target character information unit 831, the setting code character information unit 832, the test method character information unit 833, the test method graphic unit 834, and the input terminal. At least one of the graphic unit 835, the water level gauge graphic unit 836, the input terminal connection diagram unit 837, and the control character information unit 838 may be shown together.

FIG. 13 is a diagram showing a display by the external display 80 for testing the connection state between the external output terminal 70a of the water supply device 10 and the monitoring device 210 according to the second example in step S110. FIG. 13 is an example of the display in step S110 when the test button 809 of FIG. 10 is selected, and the type of information output from the external output terminal 70a is the same as the example shown in FIG. An example of the display when the user tests the connection state between the external display terminal B1 and the monitoring device 210 is shown. Hereinafter, description of the same configuration and function as in FIG. 12 will be omitted.

In the example shown in FIG. 13, the same display as in FIG. 10 is made in the area 80C below the display operation unit 80A. In the example shown in FIG. 13, the AR display button and the AR release button for the external output terminal 70a are not shown, but the AR display button and the AR release button for the external output terminal 70a are provided as in FIG. You may.

Then, in the example shown in FIG. 13, in the signal type character information unit 808, the signal type corresponding to the external output terminal 70a for which the connection test is performed is highlighted by being surrounded by a thick frame which is an example of the highlighting unit 849. There is. Specifically, here, the external display 80 determines that the external output to be tested is an inflow pressure decrease signal output from the external display terminal B1 and highlights the characters "inflow pressure decrease". Thereby, the user can easily understand that the connection test of the external display terminal B1 and the inflow pressure drop signal is performed by looking at the external display 80. The highlighting unit 849 highlights the terminal graphic unit 802 corresponding to the external output terminal 70a for which the connection test is performed, in place of or in addition to the signal type character information unit 808 corresponding to the external output terminal 70a for which the connection test is performed. It may be displayed. In the highlighting, instead of or in addition to the highlighting unit 849, it suffices to distinguish it from other terminals by lighting or blinking, font or character size, display color, and the like.

In the example shown in FIG. 13, a method of outputting an ON signal or an OFF signal from the external output terminal 70a for performing a connection test is displayed in the area 80B above the display operation unit 80A. In the example shown in FIG. 13, it is shown that the operation panel 79 is operated in order to change the inflow pressure drop signal from the OFF signal to the ON signal as a test signal. As described above, the inflow pressure decrease is turned on when the inflow pressure measured by the pressure sensor 175 is lower than the predetermined threshold value for a predetermined time. Therefore, in order to change the state, the pressure sensor 175 is used. It is necessary to change the measured value in a pseudo manner, and it is difficult to test by inputting a pseudo signal like the above-mentioned full water level. Therefore, the control unit 65 generates a pseudo inflow pressure drop signal output by a predetermined operation on the operation panel 79 by the user.

In the example shown in FIG. 13, the test target character information unit 831 and the setting code character information unit 832 are displayed. Specifically, the character information unit 831 to be tested indicates that "external output test: inflow pressure decrease" and the type of the external output signal for which the connection test is performed are the inflow pressure decrease signal. The setting code character information unit 832 displays "set value = 0", and the water tank setting, which is the setting of the city water inflow method of the water supply device, the number of water tanks connected to the water supply device, the water supply source, etc., is directly connected to the water supply method. It is shown that it is a value "0" indicating.

Further, in the example shown in FIG. 13, the test method graphic unit 834 displays an operation panel graphic imitating the operation panel 79, and further includes a test procedure graphic unit 834a and a test method character information unit 833. The test procedure graphic unit 834a indicates an operation part in the operation panel 79 and an operation part for showing the operation order thereof, and the test method character information unit 833 shows an operation procedure in which the detailed operation procedure of the operation panel 79 is shown by character information. Character information is displayed. Here, the operation panel graphic displayed on the test method graphic unit 834 may be a graphic display that matches or is deformed with the operation panel 79 of the actual water supply device 10. The arrangement of the operation part of the operation panel graphic should be the same as that of the operation panel 79. The operation part graphic shown in the test procedure graphic unit 834a shows the operation part in the operation panel 79 together with the numbers indicating the operation order (“1” to “4” in the example shown in FIG. 13). Further, the operation procedure character information shown in the test method graphic unit 834 corresponds to the operation order of the test procedure graphic unit 834a, and the detailed operation procedure of the operation panel 79 is indicated by character information. Specifically, in the example shown in FIG. 13, the operation procedure character information is "1: press the setting button", "2: display the setting code of A01 with the up and down buttons", "3: set to A01 = 1", "4: Press and hold the setting button" is displayed so that the work and its order can be understood. As described above, since the external display 80 displays the test signal output method on the test method graphic unit 834, the user who operates the external display 80 can easily operate the water supply device 10 while looking at the external display 80. And the monitoring device 210 can be confirmed.

As shown in FIGS. 12 and 13, for testing the external output terminal 70a, the method of changing the signal output from the external output terminal 70a may differ depending on the type of the output signal. Therefore, the test of the external output terminal 70a is a complicated work for a worker who is unfamiliar with the water supply device such as a building manager. On the other hand, in the method of the present embodiment, the test signal output method is displayed by the test method graphic unit 834, so that the user who operates the external display 80 outputs the external display while looking at the external display 80. The terminal 70a can be tested.

In FIGS. 12 and 13 described above, among the external display terminals A1, A2, B1, B2, and B3, the display by the external display 80 for testing the connection state between the external display terminal B1 and the monitoring device 210 is shown. The figure has been described. In step S110 of FIG. 9, it is preferable to test the connection state of the other external display terminals to be tested by using the screen provided with the test method graphic unit 834 and the like.

In the test mode, the water supply device 10 operates the external display 80 to check whether the wiring between the external output terminal 70a and the input unit 214 of the monitoring device 210 is correct, and the external output terminal 70a It is good to be able to output the connection test signal from. FIG. 14 is an example of the display in step S110 when the test button 809 of FIG. 9 is selected, and tests the connection state between the external output terminal 70a of the water supply device 10 and the monitoring device 210 according to the third example. It is a figure which shows the display by the external display 80 for this.

The external output terminal 70a outputs a connection test signal from a terminal selected by the user among the external display terminals 70a. That is, it is preferable that ON / OFF can be switched as the output of the connection test signal regardless of the input signal even for the terminal set to be switched ON / OFF based on the input of the signal at normal times such as a full water signal. The external display 80 has an output selection unit for a connection test signal for each output contact, and the control unit 65 that has received the output selection of the ON signal by the output selection unit outputs the ON signal to the corresponding external output contact. do. Specifically, as shown in FIG. 14, when the output selection units 807a1 to 807b3 corresponding to the terminals A1 to B3 of the external display terminals 70a are provided and any of the output selection units 807a1 to 807b3 is selected, The external display 80 transmits an ON signal output command of the selected external display terminal to the control unit 65 via the communication unit 73. Upon receiving the ON signal output command, the control unit 65 turns on the outputs of the corresponding external display terminals A1 to B3. In the work shown in the area 80B of FIG. 12 or 13, a signal to be output to each terminal is generated in a pseudo manner. On the other hand, in the example shown in FIG. 14, the user selects the terminal to which the connection test signal is output. By outputting the connection test signal from the output selection units 807a1 to 807b3 from the external output terminal 70a, the external output terminal 70a and the monitoring device 210 are compared with the work shown in the area 80B of FIG. 12 or 13. It can be easily determined whether or not the wiring with the input unit 214 of is made correctly. On the other hand, the method shown in FIG. 14 cannot detect an abnormality in the input terminals E11 to E33. Therefore, by performing the work shown in FIG. 12, it is possible to detect an abnormality in the input terminals E11 to E33, an erroneous wiring between the electrode type level switch 162 and the input terminals E11 to E33, and the like.

When the control unit 65 turns on the outputs of the corresponding external display terminals A1 to B3 in the output selection units 807a1 to 807b3 shown in FIG. 14, the user operates the output selection units 807a1 to 807b3 again. The output of the external display terminals A1 to B3 can be turned off. Further, in order to prevent a problem caused by forgetting to return the user, the control unit 65 automatically turns off the connection test signal after a predetermined time (for example, several seconds to several tens of seconds) has elapsed after turning on the connection test signal. It is good to do it. And / or, the external display 80 may transmit an OFF signal to the control unit 65 after a predetermined time (for example, several seconds to several tens of seconds) has elapsed after turning on the connection test signal.

The output selection units 807a1 to 807b3 shown in FIG. 14 are displayed so as to be superimposed on the display positions corresponding to the external display terminals A1 to B3 in the terminal graphic unit 802, the connection diagram graphic unit 806 and / and the signal type character information unit 808. May be good. Further, it may be displayed before or after the display shown in FIG. 12 or 13, or may be displayed superimposed on the area 80C of FIG. 12 or 13.

The connection test signal may be output from a desired external output terminal 70a by, for example, operating the operation panel 79 to set a predetermined set value to a predetermined value. By setting the set value A0 to the value 1, the inflow pressure drop signal is set to the ON signal, which is also an example of the output of the connection test signal. Further, the control unit 65 has setting codes (for example, PTa1, PTa2, PTb1, PTb2, PTb3) corresponding to the external display terminals A1 to B3, and the operation panel 79 is operated to operate the PTa1, PTa2, PTb1, PTb2. , When the setting of PTb3 is changed from the value 0 to the value 1, an ON signal is output to the external display terminals A1, A2, B1, B2, and B3.

[Test mode]
The water supply device 10 has the external output terminal 70a based on the signal from the external display 80 when the external output test display process shown in FIGS. 12 to 14 is started or when the test button 809 is pressed. It is preferable to set the test mode for testing the connection state between the and the connection destination. Further, the water supply device 10 may be changed to a signal from the external display 80, or in addition, may be set to a test mode according to the operation of the operation panel 79 by the user.

FIG. 15 is an example of a state transition diagram of the water supply device 10. The water supply device 10 has, as a control mode, a normal mode in which input / output suitable for water supply is performed, and a test mode for confirming the input / output connection. The normal mode can also be said to be a mode other than the test mode, that is, a mode other than when confirming the connection with the monitoring device 210. When the test button 809 is selected, the external display 80 transmits a signal for switching the control mode of the water supply device 10 to the test mode (step S109 in FIG. 8). The water supply device 10 receives a signal from the external display 80 to switch to the test mode, or receives a predetermined external input such as a predetermined operation of the operation panel 79 (for example, the user selects the test button 809 of FIG. 9A). And set to the test mode (see the upper arrow S150 in FIG. 15). Further, the water supply device 10 is operated when an external input indicating that the connection test is completed is made from the external display 80 (for example, when the save button 875 shown in FIG. 22 described later is selected by the user) or when the water supply device 10 is operated. When a predetermined external input such as a predetermined operation of the panel 79 is performed, the test mode is canceled and the normal mode is set (see the lower arrow S151 in FIG. 15). Further, when a predetermined time (first predetermined time, for example, several minutes, etc.) has elapsed since the water supply device 10 is set to the test mode, or when the test mode is set, the signal from the external display 80 or the operation of the operation panel 79 is predetermined. When there is no time (second predetermined time, for example, several minutes), the test mode may be canceled and set to the normal mode. As a result, it is possible to prevent a defect due to the test mode not being resolved due to the operator forgetting to operate.

Since the water supply device 10 performs input / output suitable for water supply in the normal mode, various states (for example, ON / OFF state) are determined at time intervals suitable for the detection target. Therefore, it takes at least the time interval until the output signal of the external output changes to the fixed state. For example, the above-mentioned abnormality determination such as water level detection and inflow pressure drop of the water receiving tank 160 is performed in a relatively long cycle (for example, several hundred meters to several seconds) in order to avoid erroneous detection. Therefore, in the conventional water supply device, when checking the connection state of the external output, even if a pseudo signal for changing the signal output from the external output terminal is input to the water supply device, it is actually output from the external output terminal. It takes time for the signal to change.

Therefore, the water supply device 10 of the present embodiment changes the output condition of the signal output from the external output terminal 70a between the normal mode (normal time) and the test mode. Specifically, in the test mode, the water supply device 10 has an input signal to the water supply device 10 under the test mode setting condition in which the information output from the external output terminal 70a changes faster than the setting condition in the normal time. It is advisable to set the information to be output from the external output terminal 70a based on the above. As a result, compared to the conventional water supply device, when checking the connection status of the external output, after inputting a pseudo signal to change the signal output from the external output terminal to the water supply device, it is actually from the external output terminal. It is possible to shorten the time until the output signal changes.

FIG. 16 is a flowchart showing an example of signal output processing in a normal time in a digital signal (for example, ON / OFF signal) by the control unit 65 of the water supply device 10. The signal output process in the normal time is repeatedly executed at the first time interval T1 (for example, several msec to several tens of seconds) when the water supply device 10 is in the normal mode. As an example of the digital signal, a detection signal from an electrode type level switch 162 having a plurality of electrode rods 162a to 162e can be mentioned.

In the normal signal output process, the control unit 65 acquires an input signal input to the input terminal 70b (step S202) and determines whether or not the input signal is a definite signal (step S204). In the process of step S204, it is determined whether or not it is a predetermined signal (determined signal) for each signal input to step S202. As an example, the water supply device 10 determines whether or not the input signal from the electrode rod 162e for detecting the full water level is short-circuited with the common electrode rod 162a.

When the input signal and the confirmation signal are in the same state (step S204: No), the water supply device 10 sets the value of the count C1 stored in the control memory 66 to "0" (step S212), and ends the signal output process. do. The output signal of the external output terminal 70a of the water supply device 10 is determined based on the confirmation signal. At this time, the signal output process is terminated in order to maintain the signal output as it is.

On the other hand, when the input signal and the confirmation signal are different (step S204: Yes), the water supply device 10 increments the value of the count C1 stored in the control memory 66 (step S206), and the value of the count C1 is the threshold value N1. It is confirmed whether or not it has reached (step S208). Here, as the threshold value N1, a predetermined value (for example, 3 to 10) can be used based on the type of the input signal and the time interval T1 at which the signal output process is executed. This threshold value N1 is set in order to prevent the definite signal from being determined due to noise, short-term factors such as shaking of the water surface of the water receiving tank 160, and the like. When the value of the count C1 has not reached the threshold value N1 (step S208: No), the control unit 65 of the water supply device 10 ends the signal output process in order to maintain the signal output as it is.

Then, when the value of the count C1 reaches the threshold value N1 (step S208: Yes), the water supply device 10 uses the definite signal as an input signal (step S209). Then, it is determined that the condition for outputting from the output terminal 70a based on the deterministic signal is satisfied, the output signal from the external output terminal 70a is set to the signal based on the deterministic signal (step S210), and the signal output process is performed. To finish.

FIG. 17 is a flowchart showing an example of signal output processing in a test mode for a digital signal by the control unit 65 of the water supply device 10. The signal output process in the test mode is repeatedly executed at the second time interval T2 (for example, several msec to several tens of seconds) when the water supply device 10 is in the test mode. Here, it is preferable that the second time interval T2 is equal to or less than the first time interval T1 (T2 ≦ T1) in the normal time. Here, the signal output process in the test mode is the same as the signal output process in the normal state shown in FIG. 16 in that the process of step S208A is executed instead of the process of step S208. Therefore, the same reference numerals are used for overlapping processes, and detailed description thereof will be omitted.

In the signal output process in the test mode shown in FIG. 17, in step S208A, it is confirmed whether or not the value of the count C1 has reached the threshold value N2 (step S208A). Here, the threshold value N2 used in the test mode may be a value smaller than the threshold value N1 used in the normal time (for example, 1 to 3, N1> N2). In the signal output processing in the test mode, the second time interval T2 is shorter than the first time interval T1 in the normal time, or the threshold value N2 is smaller than the threshold value N1 in the normal time. good. By doing so, in the signal output processing in the test mode, the definite signal can be determined earlier than in the normal time and output from the external output terminal 70a. As a result, the time required for confirming the connection between the water supply device 10 and the monitoring device 210 can be shortened, and the work can be simplified.

FIG. 18 is a flowchart showing an example of a normal inflow pressure drop detection process for determining a signal output of an inflow pressure drop by the control unit 65 of the water supply device 10. The normal inflow pressure drop detection process is repeatedly executed at the third time interval T3 (for example, several msec to several seconds) when the water supply device 10 is in the normal mode.

In the normal inflow pressure drop detection process, the control unit 65 determines whether or not the inflow pressure input to the input terminal 70b is smaller than the threshold value (for example, 7 mAq) (step S302). When the inflow pressure is equal to or higher than the threshold value (step S302: No), the value of the count C2 stored in the control memory 66 is set to "0" (step S310), and the inflow pressure drop detection process is terminated. At this time, the control unit 65 maintains the signal output of the inflow pressure drop from the external output terminal 70a in the previous state.

On the other hand, when the inflow pressure is less than the threshold value (step S302: Yes), the value of the count C2 stored in the control memory 66 is incremented (step S304), and whether or not the value of the count C2 reaches the threshold value N3. Is confirmed (step 306). Here, as the threshold value N3, a predetermined value can be used based on the time interval T3 at which the signal output processing is executed. As an example, the threshold value N3 can be set so that the product with the time interval T3 is about 7 seconds. When the value of the count C2 does not reach the threshold value N3 (step S306: No), the control unit 65 of the water supply device 10 ends the signal output process in order to maintain the signal output of the inflow pressure decrease as it is. The inflow pressure drop detection process is terminated.

Then, when it is repeatedly determined that the inflow pressure is less than the threshold value (S302: Yes) and the value of the count C2 reaches the threshold value N3 (step S306: Yes), the water supply device 10 determines that the inflow pressure is in a lowered state. (Step S307). Then, the water supply device 10 outputs an ON signal as an inflow pressure decrease signal from the external output terminal 70a (in the example shown in FIG. 13, the external display terminal B1) to which the inflow pressure decrease signal is assigned (step S308). The inflow pressure drop detection process is terminated.

FIG. 19 is a flowchart showing an example of inflow pressure drop detection processing in the test mode by the control unit 65 of the water supply device 10. The inflow pressure drop detection process in the test mode is repeatedly executed at the fourth time interval T4 (for example, several tens of msec to several hundred msec) when the water supply device 10 is in the test mode. Here, the fourth time interval T4 may be shorter than the third time interval T3 in the normal time.

In the inflow pressure drop detection process in the test mode, the control unit 65 of the water supply device 10 determines whether or not the inflow pressure drop test signal is input (step S402). Here, as an example, the processing of S402 may determine whether or not an external input for turning the inflow pressure drop signal into an ON signal has been made. That is, for example, when the set value A0 is changed to the value 1 as described above with reference to FIG. 13, the control unit 65 of the water supply device 10 determines that the inflow pressure drop test signal is input. When the set value A0 is not set to the value 1, the control unit 65 may determine that the inflow pressure drop test signal has not been input. When the inflow pressure decrease test signal is not input (step S402: No), the control unit 65 ends the inflow pressure decrease detection process.

When the inflow pressure drop test signal is input (step S402: Yes), the control unit 65 increments the value of the count C2 stored in the control memory 66 (step S404), and the value of the count C2 is the threshold value. Confirm whether or not it has reached N4 (S406). The count C2 may be reset to a value of 0 when the water supply device 10 is set to the test mode. The threshold value N4 is used to automatically release the inflow pressure drop signal in the test mode, and a predetermined value can be used based on the fourth time interval T4.

Then, when the value of the count C2 is less than the threshold value N4 (step S406: Yes), it is determined that the inflow pressure decrease is notified as a test signal (step S408), and the inflow pressure decrease detection process is terminated. That is, in the test mode, from the external output terminal 70a (in the example shown in FIG. 13, the external display terminal B1) to which the inflow pressure drop is assigned by, for example, the setting value A0 being changed to the value 1 by the user. An ON signal is immediately output as an inflow pressure drop signal. As a result, the time required for confirming the connection between the water supply device 10 and the monitoring device 210 can be shortened, and the work can be simplified.

When the value of the count C2 reaches the threshold value N4 (step S406: No), the control unit 65 determines that the notification of the inflow pressure decrease is canceled (step S410), and ends the inflow pressure decrease detection process. As a result, after a predetermined time (for example, several seconds to several tens of seconds) has elapsed, the inflow pressure decrease signal from the external output terminal 70a to which the inflow pressure decrease is assigned is returned to the OFF signal. In this way, it is possible to prevent problems caused by the worker forgetting to return. When the inflow pressure drop signal is returned to the OFF signal due to the value of the count C2 reaching the threshold value N4, it is advisable to display to that effect on the display operation unit 80A or the operation panel 79 of the external display 80. ..

[Display of output information from external output terminal / input of malfunction status]
FIG. 20 is a diagram showing an example of display by the external display 80 for testing the connection state between the external output terminal 70a of the water supply device 10 and the monitoring device 210. In the example shown in FIG. 20, the AR display button 810 and the AR release button 812 are omitted in the example shown in FIG. Further, in the example shown in FIG. 20, the input terminals E11 to E shown in the test method graphic unit 834 are shown.
The first confirmation information unit 880 showing the input signal in 33 as character information, the highlighting unit 881 highlighting the input signal in the input terminals E11 to E33, and the second confirmation indicating the output signal to the external output terminal 70a in character information. An information unit 882, an OK button 885 for inputting that the user has successfully completed the connection test, and an NG button 886 for inputting that the user has a problem in the connection test are added. In the example shown in FIG. 20, configurations having the same functions as the example shown in FIG. 12 are given the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 20, the external display 80 uses the test method graphic unit 834 and various status displays of the control unit 65 related to the connection test (here, the first confirmation information unit 880 and / or the highlight display unit 881). By displaying (displaying each state of the input terminals E11 to E33) together, the user can confirm whether or not the method for outputting the test signal is correctly implemented. In the example shown in FIG. 20, the electrode type level switch 162 is shown in the test method graphic unit 834. Therefore, the external display 80 acquires the detected value of the electrode type level switch 162 from the water supply device 10, and displays the first confirmation information unit 880 based on the acquired detected value. In the present embodiment, the input of E11 in the control unit 65 is ON, and in the first confirmation information unit 880, the character information "E11 input is available" is displayed. As described above, the external display 80 indicates that the short-circuiting work between the terminal E11 and the terminal E15 by the user is correctly completed by displaying the character information. In addition, the signal type corresponding to the relevant part (input terminals E11 to E33) for performing the test is highlighted by the highlighting unit 881, so that the user correctly implements the method for outputting the test signal. You can easily check whether or not it is.

Further, as shown in FIG. 20, the external display 80 may display on the display operation unit 80A whether or not the test signal is output from the external output terminal 70a for performing the external output test. In the example shown in FIG. 20, the external display 80 acquires the output information from the external output terminal 70a for performing the external output test from the water supply device 10, and based on the acquired output information, the second confirmation information unit 882 and the emphasis are made. The display unit 849 is displayed. That is, the signal type corresponding to the location to be tested (external display terminal B1) is highlighted by the highlighting unit 849. In the present embodiment, the output of B1 is ON in the control unit 65, and the character information "B1 output is available" is displayed in the second confirmation information unit 882, which corresponds to the external display terminal B1 of the terminal graphic unit 802. The highlighting unit 849 is superimposed on the portion and displayed.

Further, the test method graphic unit 834 and information for indicating the achievement of the test method by the user are displayed in the area 80B on one screen of the display operation unit 80A, and from the external display terminal B1 in the area 80C. It is shown that an ON signal as a test signal is output. As a result, the work procedure and the work result in the connection test of the external output terminal are displayed at the same time, which improves the convenience of the user.

Further, the external display 80 displays the output information currently output from the external output terminal 70a for which the external output test is performed, together with the type of the signal output from the external output terminal 70a and the external output terminal 70a. good. As shown in FIG. 20, the display of "with B1 output" by the second confirmation information unit 882, the signal type character information unit 808, and the terminal graphic unit 802 are displayed together with the area 80C. It corresponds to an example of displaying that the signal of full water for which the external output test is performed is the output information output from the external output terminal 70a. As shown in FIG. 20, the user is properly proceeding with the work by displaying on the display operation unit 80A whether or not the test signal is output from the external output terminal 70a for performing the external output test. This can be confirmed on the external display 80. The first confirmation information unit 880 may display the water level state (here, "full water input") based on the test target character information unit 831 and / or the control character information unit 838 and the like, and the second confirmation information unit 880 may display the water level state. The confirmation information unit 882 may display the type of signal to be tested (here, “full”).

When the user selects the OK button 885, it is input that the connection test of the external output terminal 70a (external display terminal B1 in the example shown in FIG. 12) for performing the external output test has been normally completed. At this time, the external display 80 may switch the display by the display operation unit 80A so as to proceed with the connection work to the connection test of the next external output terminal 70a (for example, the external display terminal B2).

FIG. 21 is a diagram showing an example of display by the external display 80 for testing the connection state between the external output terminal 70a of the water supply device 10 and the monitoring device 210. The example shown in FIG. 21 is the same as the example shown in FIG. 20, except that the display contents of the first confirmation information unit 880, the highlight display 881, the second confirmation information unit 882, and the highlight display 883 are different. The same reference numerals are used for the configurations having functions, and detailed description thereof will be omitted.

In the example shown in FIG. 21, similarly to the example shown in FIG. 20, the external display 80 acquires information on a method for outputting a test signal from the external output terminal 70a for performing an external output test from the water supply device 10. Based on the acquired information, the first confirmation information unit 880 and the highlighting 881 are displayed. In the present embodiment, as a method of outputting a test signal, the user works so that the input terminal E11 becomes an ON signal (specifically, the terminals E11 and E15 are short-circuited or the electrode rods 162a and 162e are connected). There is a need. However, in the control unit 65, only the input of the input terminal E12 is ON, and the other inputs are OFF. Therefore, in the first confirmation information unit 880, by displaying the character information "No E11 input and E12 input", the terminal E11 and the terminal E15 are not conducting, and the terminal E12 and the terminal E15 are conducting. It is shown to be doing. From such a display, the user can recognize that the work for outputting the ON signal as a full water signal from the external display terminal B1 is not correctly performed.

The first confirmation information unit 880, the second confirmation information unit 882, the highlight display 881 shown in FIG. 20, and the highlight display 881 shown in FIG. 21 may have different displays. Specifically, the first confirmation information unit 880 and the highlighting 881 of FIG. 20 use lighting and display colors (for example, red and green) indicating normality, and the second confirmation information unit 882 and the highlighting 881 of FIG. 21 are used. It is advisable to use blinking indicating an abnormality, display color (for example, red or green), enlarged display, highlighting font, or the like. In other words, the external display 80 may display differently depending on whether the output method for outputting the test signal is correctly performed or whether the test signal is output from the input / output unit 70. can.

Further, in the example shown in FIG. 21, the ON signal as a test signal is not output from the external display terminal B1 by displaying the character information "No B1 output" on the first confirmation information unit 880 (that is,). , The output of the external display terminal B1 is an OFF signal). The external display terminal B1 is a terminal to which an ON signal is output if the correct test method shown by the test method graphic unit 834 is carried out. The external display 80 has the terminal (here, B1) based on the information acquired from the control unit 65 in step S102 in order to display the test procedure graphic unit 834a and / or the test method character information unit 833 and the like. You should judge. The display of "No B1 output" shown in FIG. 21 corresponds to an example of displaying the output information currently output from the external output terminal 70a for which the external output test is performed. From such a display, the user can recognize that the ON signal is not output from the external display terminal B1 to which the ON signal is output if the correct test method is carried out.

In the state shown in FIG. 21, when the NG button 886 is selected and a defect input is made, the external display 80 short-circuits the terminal E11 and the terminal E15, which is the correct test method shown by the test method graphic unit 834.

Will be done. Therefore, when the NG button 886 is selected and a defect input is made, the external display 80 may display a method for resolving the assumed defect state in the error message 887. For example, in the example shown in FIG. 20, it is assumed that the NG button 886 is selected by the user even though the input signal and the output signal acquired from the control unit 65 by the external display 80 are correct. In this case, since the external display 80 is not displayed correctly on the monitoring device 210, it can be assumed that the user has selected the NG button 886. In that case, as a method for resolving the malfunction state, an error message 887 to the user such as "Please check if the external display terminal B1 is correctly connected to the connection destination" is displayed. At this time, it is preferable to graphically display a schematic diagram showing the arrangement location and wiring of the water supply device 10 and the monitoring device 210 as shown in FIG. The error message displayed in the error message 887 to the user may be stored in advance in the external display 80 or the storage unit 66 for each combination of the input signal and the output signal, or the input signal and the output signal are used as parameters. It may be created by a program that derives the corresponding error message.

By selecting the OK button 885 or the NG button 886, it is input that the user has completed the connection test of the external output terminal 70a (in the example shown in FIG. 12, the external display terminal B1) for performing the external output test. .. Then, when the tests of all the output terminals to be tested in the external display terminals A1 to B5 are completed, the step S110 in FIG. 8 is completed, that is, the test display is completed, and the process proceeds to the next step S118.

Returning to the description of FIG. FIG. 22 is a diagram showing an example of display of test results by the external display 80 in the present embodiment. When all the tests to be performed are completed, the external display 80 displays the test results on the display operation unit 80A (FIG. 8: step S118), and for example, the user presses an end button (not shown) to output to the outside.

If the display of the monitoring device 210 is not synchronized even though the actual water level condition of the water receiving tank 160 and the signal output from the control device 65 are synchronized, the display between the control unit 65 and the monitoring device 210 is not synchronized. It is possible that there is an abnormality in the signal line or an abnormality in the monitoring device 210. According to the system 1000 of the present embodiment, the input / output signals of the devices / monitoring devices in other places are connected and disconnected in front of each device / monitoring device, and the actual water level is changed. Since the situation can be confirmed, the location of the failure can be identified at an early stage. Further, the failure can be quickly resolved by contacting the failure status and the ordering of replacement parts from the external display via the network 300.

Further, as shown in FIG. 25, even if the remote monitoring terminal 380 is connected via the network 300 and the states of the water supply device 10, the monitoring device 210, and the water receiving tank 160 are displayed in synchronization with the remote monitoring terminal 380. good. By doing so, a plurality of people in each place can share the same external terminal information regardless of the machine side or the remote place. As a result, it is possible to perform simultaneous work on the water supply device side and a remote place, and it is possible to shorten the work time. It is no longer necessary to prepare separate drawings such as paper for the information of various wiring diagrams at the water supply device side and the remote location, and based on the shared drawings, work from the remote monitoring terminal 380 when working near the water supply device or the water receiving tank. It is also possible to give instructions and respond to inquiries. Connection at the time of inspection If the save button 875 (see FIG. 22) is pressed at the end of the test and a transmission function is provided to send the test result to the external server 400, the status of the end of the test can be displayed immediately or in the history on the remote monitoring terminal. Can be confirmed as. In addition, as described above, if a failure or malfunction occurs during inspection or the like, information can be shared with the water supply device side at a remote location, so that the initial response to the failure can be performed quickly.
