Description

[Technical Field]

[0001] The present invention relates to a fixture control and monitoring system that includes at least one fixture that can accommodate multiple aquariums, and a master device that is provided for each fixture and controls and monitors the aquariums, as well as the master device and detection unit slave unit used in this system. [Background technology]

[0002] Pet shops and other stores have fixtures with many aquarium tanks for selling ornamental fish. These tanks contain many aquarium fish and aquatic plants, and the water deteriorates faster than in the aquarium environment of a general aquarium owner. In addition, water changes are necessary to physically remove nutrients such as ammonia excreted by the fish in order to maintain their health.

[0003] As the water in the tank becomes dirty over time, it becomes necessary to drain the water and refill it with new water.

[0004] In addition, to maintain a proper environment within the aquarium, it is necessary to constantly monitor the temperature and water quality within the tank to ensure that ornamental fish are kept healthy and to be able to properly determine when to change the water.

[0005] To address this issue, an aquarium management system is known, as disclosed in Patent Document 1 below. This aquarium management system includes a water quality inspection unit that measures the temperature and pH of the water in the aquarium, a water quality management unit that manages changes in the water quality of the aquarium based on data from the inspection unit and displays measured values, warnings, etc. externally, a water quality adjustment unit that adds disinfectants, food, pH adjusters, etc. to the water in the aquarium in response to output signals from the management unit, and a water volume adjustment unit that adjusts the volume of water in the aquarium.

[0006] Patent Document 1 discloses a system configuration for multiple aquariums, not just one aquarium. Multiple aquariums are installed, each equipped with a water quality testing unit, a water volume adjustment unit, and a water quality control unit. Measurement data sent from each water quality testing unit is sent to a single water quality control unit, and the water quality control unit sends commands to each water volume adjustment unit and each water quality adjustment unit to adjust the water quality and water volume appropriate for each tank based on the transmitted measurement data, thereby centrally managing each aquarium.

[0027] <Overall system configuration> A preferred embodiment of a fixture control and monitoring system according to the present invention will be described first. FIG. 1 is a schematic diagram showing the overall configuration of the fixture control and monitoring system. A fixture 100 is installed in a storefront or the like, with multiple aquariums mounted thereon. Details of the fixture 100 will be described later. A master unit 200 (corresponding to a master device) is mounted on the fixture 100. The master unit 200 has functions such as water supply and drainage control for the aquariums mounted on the fixture 100. A lighting unit 300 is equipped with a drive circuit and a power supply unit for lighting the fixture 100. Each aquarium is provided with lighting, and although LED lighting is used, other types of lighting may also be used. The lighting unit 300 is connected to the master unit 200 (indicated by L2), and its on / off state is controlled via the master unit 200. A plurality of fixtures 100 are installed, and each fixture 100 is equipped with a master unit 200 and a lighting unit 300. The fixtures 100 are not necessarily configured with the same shape, size, or number of aquariums, and various aquariums are installed depending on the store's needs.

[0028] The operation device A issues commands to the master unit 200 to control the fixture 100 (aquarium). The operation device A is equipped with a wireless connection device 500 that is connected to the operation panel 400 wirelessly, such as via Wi-Fi. The operation panel 400 is connected to the master unit 200 via a wired connection (indicated by L1). However, whether the connection is wireless or wired can be determined as appropriate. The wireless connection device 500 is connected to a system consisting of a web screen, and has some functions in common with the operation panel 400. The system may be configured with both the operation panel 400 and the wireless connection device 500, or with only one of them.

[0029] As an example, operation panel 400 is configured as a dedicated device, and wireless connection device 500 transmits and receives data to and from a system configured with a web screen, and can be provided with the same functions as operation panel 400 using a general-purpose computer such as a personal computer or a mobile terminal such as a smartphone. In addition, data collected from master unit 200 is displayed on the web screen.

[0030] 1, the master unit 200 and the lighting unit 300 are shown as being installed on the top surface of the fixture 100, but the location where they are installed relative to the fixture 100 can be determined as appropriate and is not limited to a specific location. It is also optional whether they are installed directly on the fixture 100 or at a distance. The location in the store where the operating device A is installed, or whether it is installed so that it can be operated remotely, can also be determined as appropriate.

[0031] The number of fixtures 100 to be installed can be determined as appropriate, but they can be centrally controlled and managed by a single operating device A. One master unit 200 and one lighting unit 300 are assigned to each fixture 100, but control commands for each fixture 100 are issued by an operating device A installed in one location. This allows multiple fixtures 100 to be centrally managed (monitored) and controlled.

[0032] <Furniture composition> 2 is a schematic diagram showing the general configuration of the fixture 100 and the master unit 200. A large number of aquariums 1 are placed on the fixture 100. The aquariums 1 contain aquarium fish and other creatures for sale, as well as aquatic plants.

[0033] As shown on the right side of Figure 2, the fixture 100 is configured with three tiers, an upper tier, a middle tier, and a lower tier, and from top to bottom, three, six, and two aquariums 1 are placed on it. Note that the above configuration is an example, and the number of tiers and the number of aquariums 1 can be determined as appropriate.

[0034] Each stage is provided with a flip-up plate 101, which can be flipped up and rotated by a hinge mechanism 102, allowing living organisms to be removed from the aquarium 1 or new living organisms to be added. The flip-up plate 101 itself is a well-known structure.

[0035] A detection slave unit 250 is provided on the back side of the flip-up plate 101. One detection slave unit 250 is provided for each aquarium 1. A water temperature sensor 270 and a water quality sensor 271 are provided in each aquarium 1 (see FIG. 4) and are connected to the detection slave unit 250. The detection slave unit 250 is also electrically connected to the master unit 200, and the temperature data and water quality data measured by the detection slave unit 250 are transmitted to the master unit 200. In other words, the master unit 200 functions as a detection master unit.

[0036] The left side of Figure 2 shows the surface (display section) of the master unit 200. The valve body indicator 201 has three LEDs that indicate the water supply and drainage status. When water supply and drainage are performed, the valve body is controlled to open and close as described below. The right LED (green) is always lit, indicating that water supply and drainage commands can be issued. When the middle LED (yellow) is lit, it indicates that water supply and drainage are being performed. When this LED is lit, no water supply and drainage related operations can be performed. The left LED (red) indicates that water supply and drainage are not possible due to some kind of abnormality.

[0037] The power indicator 202 indicates any power abnormalities. If there are no abnormalities, the indicator is off. Two power systems are measured; in the case of a single filtration system, the first system monitors the power of the aquarium heater, and the second system monitors the power of the lighting, blower, and water tank heater. The blower has the function of sending air into the aquarium. When the power of one system exceeds a specified wattage, it flashes red to indicate an abnormality.

[0038] In the case of a centralized filtration system, the first system monitors the power of the aquarium heater and water tank heater, and the second system monitors the power of the lighting, blower, and pump.Individual filtration system and centralized filtration system will be discussed later.

[0039] The detection unit indicator 203 notifies the user if an abnormality occurs in the water temperature or water quality in any of the aquariums 1. When normal, the LED remains off. When it flashes, it indicates that the water temperature or water quality value is outside the threshold. In this case, predetermined measures such as water supply and drainage should be taken. When the LED lights up, it indicates that a communication error or the like has occurred.

[0040] The segment display section 204 indicates the unit number of the fixture 100. In the illustrated example, the fixture 100 is indicated by a two-digit number. Each fixture 100 is assigned a unique number.

[0041] <Detection unit slave unit> FIG. 3A shows the configuration of the front side of the detection unit slave unit 250, and FIG. 3B shows the configuration of the back side of the detection unit slave unit 250. The water temperature indicator 251 is off if the water temperature is a normal value within the threshold value, and flashes if the threshold value is exceeded. The water quality indicator 252 is off if the water quality is a normal value within the threshold value, and flashes if the threshold value is exceeded. The segment display unit 253 alternately displays the water temperature and water quality. For example, the water temperature is displayed as 25°C, and the water quality is displayed as pH 7.0. A hole is formed in the flip-up plate 101 so that the segment display unit 204 can be seen.

[0042] A communication line connection section 254 and a power line connection section 255 are provided on the top of the detection unit slave unit 250. A water temperature sensor 270 such as a thermistor is connected to the water temperature sensor connection section 256. A water quality sensor 271 is connected to the water quality sensor connection section 257. The water temperature sensor 270 and the water quality sensor 271 are attached to appropriate locations within the aquarium 1, and general-purpose sensors can be used for each sensor.

[0043] A threshold setting unit 258 is provided, which allows upper and lower limits to be set for water temperature and water quality. A detection slave unit 250 is provided for each aquarium 1, so thresholds can be set for each aquarium 1. A slave number setting unit 259 is provided, and the slave number can be set using a DIP switch. This allows a specific number to be assigned to the aquarium 1 to which each detection slave unit 250 is attached, making it possible for the master unit 200 and operating device A to recognize a specific aquarium 1. Specifically, a tank number (1-1, 1-2, etc.) is assigned as shown in Figure 6B.

[0044] <control block> FIG. 4 is a control block diagram of the fixture control and monitoring system. The master unit 200 is equipped with a water supply and drainage control unit 220, and controls the opening and closing of various valve bodies that make up the valve body unit B, thereby controlling water supply and drainage. Specific water supply and drainage control will be described later. In this embodiment, a program (software) for water supply and drainage is stored, and water supply and drainage are carried out in accordance with this program. The water supply and drainage control unit 220 is also provided with a timer function for automatically carrying out water supply and drainage, and the program is executed based on this.

[0045] The status detection unit 221 detects the water temperature and water quality of the aquarium 1 (whether it is within the threshold range, etc.). The detected data, etc. is sent to the operation device A. The status detection unit 221 detects and monitors the water temperature and water quality based on the measurement data from the detection unit slave unit 250. The detection results are displayed on the detection unit indicator 203.

[0046] The power measurement unit 222 measures the power of the two systems as described above. If an abnormality occurs, it is displayed on the power unit indicator 202 as described above. The display unit 223 includes various indicators 201, 202, and 203 as described above.

[0047] The detection slave unit 250 has a display unit 260, which includes the water quality indicator 252 and segment display unit 253 described above. The threshold setting unit 258 has the function of setting the threshold values ​​for water temperature and water quality, as described above. The threshold setting unit 258 can be configured with setting buttons, etc. The data transmission unit 262 has the function of transmitting measured water temperature and water quality data to the master unit 200. Upper and lower limits can be set for the threshold values, and if the value deviates from the set threshold values ​​(an abnormality notification), the data is sent to the master unit 200 and also to the operating device A, allowing centralized management via a web screen (as exemplified in Figures 6B and 6E).

[0048] As described above, the lighting unit 300 drives the lighting that constitutes the lighting section 301. The lighting is constituted by LEDs or the like, and provides illumination to appropriate locations within the fixture 100 and the aquarium 1.

[0049] The operation panel 400 has the functions of a water supply and drainage command section 401, a fixture selection section 402, a water tank selection section 403, and a drainage level selection section 404. The web screens (FIGS. 6A and 6D) described later also have the same functions.

[0050] <Operation panel> 5 is a diagram showing the operation screen of the operation panel 400. The fixture unit display section 410 displays a two-digit segment number and displays the number of the currently selected fixture 100. The fixture selection section 402 allows the user to select the fixture 100 to be supplied with water or drained by operating the up and down arrow operation sections. Operating the fixture selection section 402 increases or decreases the numerical value in the fixture unit display section 410.

[0051] The water tank selection section 403 is provided with buttons for specifying the top, middle, and bottom tiers. As explained in FIG. 2, this button arrangement corresponds to the fact that the fixture 100 is configured in three tiers. When all of the buttons for the top, middle, and bottom tiers are pressed, all of the water tanks 1 placed on that fixture 100 become the subject of water supply and drainage control. When a button is pressed, the lamp adjacent to it lights up, allowing the selection status of each tier to be visually confirmed. It is also possible to select any one or two of the top, middle, and bottom tiers. The appropriate selection can be made while checking the water quality status.

[0052] The drainage level selection section 404 is a button for selecting either the first drainage level or the second drainage level. Details of the first drainage level and the second drainage level will be described later. It is possible to set an appropriate drainage amount taking into consideration the level of water pollution of the aquarium 1, etc. When the button is pressed, the lamp adjacent to it lights up, so it is possible to visually see which drainage level has been selected.

[0053] The water supply and drainage command unit 401 is provided with an execute button and a stop button. Pressing the execute button executes water supply and drainage for the selected fixture 100. Pressing the stop button stops the water supply and drainage operation. When the execute button 401 is pressed, the lamp adjacent to it lights up to indicate that water supply and drainage is in progress.

[0054] A water tank water supply button 411 and a filtered water tank water supply button 412 are provided and are used in the case of the centralized filtration method described below. When a button is pressed, the lamp adjacent to it lights up to indicate that the water supply process is in progress.

[0055] The main power button 413 is a button for using the operation panel 400. When the main power button 413 is pressed, the adjacent lamp lights up, and when it is pressed again, the lamp goes out and the power is turned off. The lighting button 414 is a button for turning on and off the lighting at each location of the furniture 100 and the water tank 1 in a batch. When the lighting button 414 is pressed, all the lighting lights up in a batch, and when it is pressed again, it goes out in a batch. While the lighting is on, the lamp adjacent to the button lights up. Note that the various buttons are touch-operated buttons.

[0056] <WEB screen> Figures 6A to 6F are diagrams showing a configuration example of an operation screen of a WEB system connected by Wi-Fi or the like from the wireless connection device 500. Figure 6A shows a furniture selection screen. Buttons for selecting the furniture 100 are arranged in the furniture selection section 501. Furniture numbers are displayed on the buttons, and any one of them can be selected. This has the same function as the furniture selection section 402 of the operation panel 400. The lighting button 502 has the same function as the lighting button 414 of the operation panel 400. When the water supply and drainage button 503 is pressed, the screen shown in Figure 6D is displayed. The switching button 504 is a button for switching and displaying the water temperature, water quality, and power. Note that the various buttons are operation buttons on the WEB screen.

[0057] Figure 6D shows the screen configuration for performing water supply and drainage. The various buttons shown here have the same functions as the water tank selection section 403, the drainage level selection section 404, and the water supply and drainage command section 401 described in Figure 5.

[0058] In FIG. 6A, when fixture number 01 is selected and water temperature is selected using switch button 504, the screen shown in FIG. 6B is displayed. Here, aquarium 1 placed on fixture 100 is displayed schematically. Numerical values ​​are displayed within the box representing aquarium 1, with the upper number indicating the aquarium number (1-1, 1-2, etc.) and the lower number indicating the water temperature (24.5, 25.0, etc.). This screen allows the water temperature status of each aquarium to be confirmed at a glance. Selecting a aquarium on this screen allows the status to be confirmed in more detail. Here, aquarium 1 is displayed schematically, corresponding to the arrangement of aquarium 1 in FIG. 2. The displayed water temperature is the data transmitted from master unit 200.

[0059] FIG. 6E displays the water temperature history of the aquarium selected on the screen of FIG. 6B. The horizontal axis represents time, and the vertical axis represents water temperature. This graph allows the user to monitor the water temperature status. It is also possible to check whether the temperature is outside the threshold range. This threshold is a value set in the detection unit slave unit 250.

[0060] FIG. 6C is a screen showing the power (W) of the selected aquarium. As mentioned above, the power of two systems is measured, and the measured values ​​(unit: W) are displayed. FIG. 6E is a screen showing the power history. This allows the power status to be monitored. It is also possible to check whether any abnormalities have occurred in the power value. This power value is data measured by the power measurement unit 222 of the master unit 200.

[0061] <Configuration of siphon mechanism> Figure 7 is a schematic diagram showing the configuration of the drainage device according to this embodiment. The drainage device is surrounded by a partition plate 29 (shown by a dashed line in Figure 7). The partition plate 29 is L-shaped in plan view and surrounds the corners of the aquarium 1 to prevent ornamental fish (living creatures) from approaching the periphery of the overflow pipe 3. This prevents ornamental fish from getting caught when draining water. In addition, multiple slits 29a are formed in the upper and lower parts of the partition plate 29 to allow water in the aquarium to pass through.

[0062] The drainage device includes a siphon mechanism 2. The siphon mechanism 2 is composed of a siphon pipe 20 and a cylindrical portion 30. The siphon pipe 20 is connected to an overflow pipe 3. FIG. 11 is a schematic perspective view showing only the siphon mechanism 2. FIG. 12 is a plan view of the siphon mechanism 2 shown in FIG. 11.

[0063] The siphon pipe 20 has a U-shaped pipe shape overall. The siphon pipe 20 is composed of a first vertical pipe section 21, a U-shaped pipe section 22, a second vertical pipe section 23, and a connecting pipe section 24. The shape of the siphon pipe 20 and the number of pipe sections it is made of can be selected as appropriate. The first vertical pipe section 21, the U-shaped pipe section 22, the second vertical pipe section 23, and the connecting pipe section 24 are made of an appropriate material such as glass or resin. Furthermore, the first vertical pipe section 21, the U-shaped pipe section 22, and the second vertical pipe section 23 shown in FIG. 6 are preferably detachable from each other so that they can be easily cleaned of clogs and the like.

[0064] The first vertical pipe section 21 has a first opening 21a at its upper end. The two open upper ends of the U-shaped pipe section 22 are connected to the lower end of the first vertical pipe section 21 and the lower end of the second vertical pipe section 23. The lower end of the second vertical pipe section 23 is connected to one of the upper ends of the U-shaped pipe section 22, and its upper end is connected to the lower end of the connecting pipe section 24. The connecting pipe section 24 has an inverted L-shape, and its lower end is connected to the upper end of the second vertical pipe section 23, while its horizontal end (first connecting section 24a) is connected near the center of the overflow pipe 3. The overflow pipe 3 is installed vertically, and an open opening 3a is formed at its upper end, and an open opening 3b is also formed at its lower end. If water is poured into the overflow pipe 3 beyond its upper end, it will overflow and flow into the interior of the overflow pipe 3. In other words, the overflow pipe 3 is cylindrical. Furthermore, when a living organism is received, a living organism bag may be floated in the aquarium 1 for a predetermined time to adjust the water temperature and quality. In this case, an overflow pipe 3 is provided to prevent water from overflowing from the aquarium 1. When a living organism is received, water is drained from the overflow pipe 3, and a siphon action does not start, as in the structure of Patent Document 1. In other words, when a living organism is received, unintended drainage by the siphon pipe does not start.

[0065] The cylindrical portion 30 has a second opening 30a formed at its lower end so that the first opening 21a of the first vertical pipe portion 21 of the siphon pipe 20 can be inserted therein. The inner diameter of the cylindrical portion 30 is set to be larger than the outer diameter of the first vertical pipe portion 21. This forms a gap S between the cylindrical portion 30 and the siphon pipe 20. The second opening 30a is set to be located lower than the first opening 21a.

[0066] The upper part of the cylindrical part 30 is formed in a hemispherical shape and is closed, but a second connection part 30b is provided in the center part. As will be described in detail later, air flows in and out through this second connection part 30b.

[0067] <Drainage system configuration> Next, the configuration of the drainage system according to the present invention will be described. Fig. 8 is a schematic diagram showing an overview of the drainage system provided in the fixture 100. For ease of explanation, elements unrelated to the drainage system have been omitted. Fig. 9 is a schematic diagram showing the configuration of a first embodiment of a water supply system used in the fixture 100. For ease of explanation, other elements have been omitted. Fig. 10 is a schematic diagram showing the configuration of a second embodiment of a water supply system used in the fixture. For ease of explanation, other elements have been omitted. Any of the embodiments may be adopted as the present invention.

[0068] As shown in Figure 8, fixture 100 installed in a store or the like has a number of aquariums 1 arranged on a display shelf (not shown). The arrangement of the aquariums 1 is the same as that shown in Figure 2. Each aquarium 1 is provided with a drainage device as described in Figure 7.

[0069] An air inlet / outlet pipe 40 is installed horizontally above the water tank 1 on each level, and air is sent in from the air pump 5 via a vertically arranged air supply pipe 45. The air inlet / outlet pipe 40 and the air supply pipe 45 are connected by a joint 46. A first valve body 41 and a second valve body 42 (these are elements included in the valve body section B in Figure 4) are installed in the air inlet / outlet pipe 40. These valve bodies are controlled by the water supply / drainage control unit 220. When air is sent into the drainage device, the first valve body 41 is opened, allowing air from the air pump 5 to flow into the drainage device. The outside of the second valve body 42 (the left side of the figure) is open to the atmosphere, and by opening the second valve body 42, the air inside the drainage device can be released to the atmosphere.

[0070] The air inlet / outlet pipe 40 and the second connection part 30b are connected via a one-way cock 43 and a vertical pipe 44. By controlling the air pump 5, the first valve body 41, and the second valve body 42, the second connection part 30b of the siphon mechanism 2 can be selectively connected to the air pump 5 or the atmosphere. For example, by opening the first valve body 41 and closing the second valve body 42, air can be sent from the air pump 5 into the cylindrical part 30 of the siphon mechanism 2. Furthermore, by closing the first valve body 41 and opening the second valve body 42, air inside the cylindrical part 30 can be released to the atmosphere. The vertical pipe 44 can be, for example, a flexible air tube.

[0071] The flow path from the air pump 5 through the first valve body 41 to the second connection part 30b corresponds to the first flow path, and the flow path from the second valve body 42 communicating with the atmosphere to the second connection part 30b corresponds to the second flow path.

[0072] It is necessary to constantly supply air (oxygen) to each aquarium 1, which is also achieved by the air pump 5. The piping from the air pump 5 can be branched to supply air to the siphon mechanism and to the aquarium. Alternatively, although there is one air pump 5, separate independent piping configurations may be used, or separate air pumps may be used.

[0073] As shown in Figure 8, water that flows into the overflow pipe 3 falls from the opening 3b at the bottom end of the overflow pipe 3. As indicated by arrow 8, the falling water enters the opening 3a of the overflow pipe 3 located directly below. For this purpose, an attachment (not shown) is provided as a flow path to connect the opening 3b of the upper overflow pipe 3 with the opening 3a of the middle overflow pipe 3. This attachment is detachable. The diameter of the attachment is set so that it does not obstruct the inflow of water from the opening 3a.

[0074] A similar attachment is provided when water falls from the middle overflow pipe 3 to the lower overflow pipe 3. The water falling from the lower overflow pipe 3 will be explained with reference to Figures 9 and 10. The flow path configuration for water discharged from the overflow pipe 3 is not limited to the above, and other embodiments can be adopted. For example, the water may be configured to be collected in a horizontally arranged drain pipe.

[0075] <Single filtration method> Figure 9 shows the configuration of a water supply system using a single filtration system. The drainage system described in Figure 8 is used, but for ease of explanation, it is not shown in the figure. Since the water in the aquarium 1 becomes contaminated, a mechanism for filtering the water is necessary, but in the single filtration system, a filtration device is used for each aquarium 1. Note that well-known filtration devices can be used, and so illustrations and explanations of the filtration device are omitted.

[0076] A water tank 6 is placed on top of the fixture 100. Water (breeding water) is supplied from the water tank 6 to each aquarium 1. A float valve 6a is provided inside the water tank 6, which operates to close a valve body 66 (corresponding to the water tank valve body) when the tank is full. The water tank 6 is provided with a valve body 66 and a manual valve 67, and tap water is normally supplied from upstream via the valve body 66. If the valve body 66 cannot be used due to a malfunction or other reason, the manual valve 67 can be operated to allow water to be supplied.

[0077] A first horizontal pipe 61 (three locations) and a second horizontal pipe 60 (one location) are arranged above each tier of fixtures 100. The first horizontal pipe 61 and the second horizontal pipe 60 are connected to vertical pipes 62 (two locations) on the left and right. A valve body 63 (corresponding to a water supply valve body) and a manual valve 64 are provided on both the left and right sides of the first horizontal pipe 61. A valve body 65 is provided in each water tank 1. Normally, water is supplied from the water storage tank 6 to each water tank 1 by opening the valve body 63. If the valve body 63 cannot be used due to a malfunction or other reason, the manual valve 64 can be operated to supply water. The opening and closing of the valve bodies 63, 65, and 66 is controlled by the water supply and drainage control unit 220.

[0078] Water that falls from the overflow pipe 3 of the water tank 1 on the lower level is collected by a horizontally arranged drain pipe 80 and sent to a drainage path (not shown) by a recovery pipe 68. A sensor is provided in the recovery pipe 68 to detect the amount of water passing through. A diagonal cut 68a is formed in the recovery pipe 68, making it easier to detect the amount of water. This sensor makes it possible to detect the drainage status (start and end).

[0079] Commands for draining or supplying water are given via the operation panel 400 or wireless connection device 500 described above.

[0080] <Centralized filtration method> Figure 10 shows the configuration of a centralized filtration water supply system. The drainage system described in Figure 8 is used, but is not shown for the sake of clarity. The configuration related to the water tank 6 located above the fixture 100 is the same as in Figure 8. A filtered water tank 7 is located below the fixture 100, and water filtered by this filtered water tank 7 is supplied to each water tank 1. Therefore, each water tank 1 is not equipped with a filtration device.

[0081] The filtered water tank 7 is provided with a float valve 7a, which closes a valve element 76 (corresponding to the water tank valve element) when the tank is full of water. The water tank 6 and the filtered water tank 7 are connected by a vertical pipe 70. A valve element 76 is provided, and water is supplied to the filtered water tank 7 by opening the valve element 76. If the valve element 76 cannot be used due to a malfunction or the like, water can be supplied by operating a manual valve 77. Each valve element shown in Figure 10 is controlled by the water supply and drainage control unit 220.

[0082] Water is supplied from the filtration tank 7 to each tank 1 via horizontal piping 73 and vertical piping 72. By opening valve body 75 (corresponding to the water supply valve body), water is supplied to each tank 1 by water supply pump 71. Each tank 1 is provided with a water supply valve 74, through which water is supplied into the tank. Water drained from each tank 1 by the drainage device is sent back to the filtration tank 7 via the overflow pipe 3 provided in each tank 1, and is supplied again in a filtered state to each tank 1. In this way, the water is circulated and used while being filtered. When water is circulated, water overflowing from the overflow pipe 3 of the drainage device returns to the filtration tank 7. Water moves from the upper to the middle tank and from the middle to the lower tank along arrow 8, as described above, using attachments (not shown).

[0083] Furthermore, water that falls from the overflow pipe 3 of the lower tank 1 is collected by a horizontal pipe 80 and returned to the filtration tank 7 by a vertical pipe 81. The water returned to the filtration tank 7 is filtered and then sent again to each tank 1 by the water supply pump 71.

[0084] When water is discharged by the siphon mechanism 2, the valve element 75 of the vertical pipe 72 is closed. In this case, the valve element 72 is opened so that the water pumped by the water supply pump 71 is returned to the filtered water tank 7 via the valve element 72. The valve element 72 is closed during normal use.

[0085] The filtration tank 7 is provided with a drain outlet 78. When water is discharged using the siphon mechanism 2 of each tank 1, a large amount of wastewater flows into the filtration tank 7, so the overflowing water is discharged from the drain outlet 78.

[0086] <Drainage action> Next, we will explain the operation of the drainage device and drainage system described in Figures 7, 8, and 11. In this embodiment, when draining water from the aquarium 1 for a water change, the amount of water to be drained can be set to two levels (first drainage level and second drainage level).

[0087] 13A to 13D are diagrams illustrating the operation of the siphon mechanism at the first drainage level. When the siphon mechanism is not operating (when water is not being drained due to water changes), the first valve body 41 in FIG. 8 is open and the second valve body 42 is closed. Air is then pumped into the siphon mechanism 2 of each aquarium 1 by the air pump 5. As shown in FIG. 13A, air has entered up to the position of the opening 30a of the cylindrical portion 30. The area into which air has entered is indicated by a diagonal dashed line. Air has entered the gap S, and siphon action by the siphon mechanism 2 is not performed. In this state, the water surface W1 is located at the opening 3a at the upper end of the overflow pipe 3. The first valve body 41 and the second valve body 42 are controlled by the water supply and drainage control unit 220 (see FIG. 4).

[0088] To maintain a constant air pressure inside the cylindrical portion 30, the siphon pipe is formed in a U-shape and is connected to the overflow pipe 3 at the center of the overflow pipe 3. This allows water to be constantly stored in the U-shaped portion including the U-shaped pipe portion 22, allowing air pressure to be applied in a stable state.

[0089] <Water supply and drainage procedures> Next, the procedure for water supply and drainage will be explained using the flowchart in Figure 15. First, the main power button 413 on the operation panel 400 is turned on (S100). Next, the fixture 100 to be water supply and drainage is selected (S101). The up and down arrow buttons on the fixture selection section 402 are operated to confirm the fixture number on the fixture unit display section 410. At this time, the number (furniture number) on the segment display section 204 of the master unit 200 flashes, allowing the target fixture 100 to be confirmed.

[0090] Next, the tank to be water-supply / drained is selected by the tank selection unit 403 (S102). Specifically, the upper, middle, or lower tank can be selected. When changing the water in all tanks, the buttons for all tanks are pressed.

[0091] Next, the water supply and drainage level is set (S103). Either the first or second water supply level is selected using the water supply level selection unit 404. Next, water supply and drainage is started by pressing the execute button on the water supply and drainage command unit 401 (S104). When the execute button is pressed, the valve body indicator 201 of the master unit 200 lights up. The water supply and drainage operation differs depending on the selected water supply level and the filtration method, so they will be explained step by step below.

[0092] <First drainage level drainage operation (single filtration method)> First, the drainage operation in the single filtration system shown in FIG. 9 will be described with reference to the flowchart in FIG. 16A. To start the drainage operation, the execute button is operated as described above. This activates the siphon mechanism 3, closing the first valve body 41 (S11) and then opening the second valve body 42 (S12). The time interval between steps S11 and S12 can be set as appropriate. This connects the second connection portion 30b of the cylindrical portion 30 to the atmosphere, and the air inside the cylindrical portion 30 is pushed out. As a result, water in the water tank 1 enters the cylindrical portion 30 through the gap S, as shown by the arrows in FIGS. 13B and 13D, and the siphon action begins. The water that has entered the gap S then enters the siphon pipe 20 and moves into the overflow pipe 3. As a result, the water level W1 gradually drops, and the drainage operation progresses. Note that steps S11 and S12 may be performed simultaneously.

[0093] 13C, the siphon action ends and the draining operation is completed when the water surface W2 drops to the height of the first opening 21a of the siphon tube 20. Note that, since the second connecting part 30b remains open to the atmosphere, air exists up to the position of the first opening 21a.

[0094] Completion of the drainage operation is determined by whether a first predetermined time has elapsed based on the timer function of the water supply and drainage control unit 220 (S20). The first predetermined time can be set and stored in advance, taking into account the time it takes for the water surface W2 to fall to the height of the first opening 21a. The first predetermined time is set as the elapsed time based on the time when the command is given by the operation panel 101 or step S11.

[0095] After the first predetermined time has elapsed, the second valve body 41 is closed (S22) and then the first valve body 41 is opened (S23) to start the subsequent water supply operation. The time interval between steps S22 and S23 can be set appropriately. Note that steps S22 and S23 may be performed simultaneously.

[0096] <Second drainage level drainage operation (single filtration method)> First, the drainage operation in the single filtration method shown in FIG. 9 will be described with reference to the flowchart in FIG. 16B.

[0097] 14A and 14B are diagrams illustrating the operation of the siphon mechanism 2 at the second drainage level. The state in which the siphon mechanism 2 is not in operation is as described above.

[0098] When the siphon mechanism 2 is operated, first, the first valve body 41 is closed (S11), and the second valve body 42 is opened (S12). Up to this point, the process is the same as that described with reference to FIG. 11A. The air inside the cylindrical portion 30 is released to the atmosphere, and water enters the cylindrical portion 30 through the gap S (FIG. 14A). This causes the water level W2 to gradually drop. Then, when the cylindrical portion 30 is filled with water, the second valve body 42 is switched from open to closed (S14).

[0099] The timing for switching the second valve body 42 from open to closed is determined based on the timer function of the water supply and drainage control unit 220, and is determined by whether a second predetermined time has elapsed (S13). The second predetermined time can be set and stored in advance, taking into account the time it takes for the cylindrical portion 30 to be filled with water. When the second predetermined time has elapsed, the second valve body 42 is closed.

[0100] 14B, when the water level W3 drops to the position of the second opening 30a at the bottom end of the cylindrical portion 30, air enters the cylindrical portion 30 through the second opening 30a, and the drainage action by siphon action ends. Once the drainage action is complete, the first valve body 41 is opened (S22). The timing for opening the first valve body 41 is determined based on whether a third predetermined time has elapsed after step S14 (S20). The third predetermined time can be set and stored in advance, taking into account the time it takes for the water level W3 to drop to the position of the second opening 30a.

[0101] As described above, drainage can be performed at two levels. The operator can select the water level at which to drain using the drainage level selection section 404 on the operation panel 400. The drainage operation can be started after checking the degree of contamination of the water in the tank.

[0102] Furthermore, the draining operation for changing the water may be performed automatically at regular intervals using a timer function. The time period for starting draining may also be set in advance, so that the system will automatically start when that time arrives. The setting can also be changed for each stage. The type of draining to be performed may be determined in advance by creating a computer program.

[0103] <First drainage level drainage operation (centralized filtration method)> Next, the drainage operation at the first drainage level in the centralized filtration method will be described with reference to the flowchart in FIG. 16C.

[0104] In the case of the centralized filtration system, prior to controlling the first valve body 41 and the second valve body 42, the valve body 72 is opened (S1), and then the valve body 75 is closed (S2). This is to prevent water from being supplied to each water tank 1 during the draining operation. Note that steps S1 and S2 may be performed simultaneously.

[0105] Thereafter, the drainage operation is actually performed, but steps S11 to S22 are the same as those in FIG. 16A, so the explanation will be omitted.

[0106] <Second drainage level drainage operation (single filtration method)> Next, the drainage operation at the second drainage level in the centralized filtration method will be described with reference to the flowchart in FIG. 16D.

[0107] Steps S1 and S2 are the same as in Figure 16C. Steps S11 to S22 are the same as in Figure 16B. Therefore, the description will be omitted.

[0108] <Water supply action> Next, the water supply operation after the drainage operation is completed will be described. The water supply operation is automatically started after the drainage operation is completed.

[0109] <First drainage level water supply operation (single filtration method)> The water supply operation at the first drain level is shown in the flowchart of Figure 16A, which has already been described in the drain operation. After the first valve body 41 is opened in step S22, the water supply valve body (valve body 63) is opened (S23). This starts the supply of water to the selected aquarium 1. After a fourth predetermined time has elapsed (S30), the water supply valve body is closed (S31), and the supply of water to the aquarium 1 ends. The fourth predetermined time can be set and stored in advance, taking into account the time when the water supply will be completed.

[0110] After water supply to water tank 1 is completed, water is supplied to water storage tank 6. This can be started by pressing water storage tank water supply button 411. First, the water storage tank valve body (valve body 66) is opened (S32). This starts water supply to water storage tank 6. After a fifth predetermined time has elapsed (S33), the water storage tank valve body is closed (S34), completing water supply to water storage tank 6. As described above, water supply to water tank 1 and water storage tank 6 after the draining operation is completed is also performed automatically. This also applies to the content explained below.

[0111] <Second drainage level water supply operation (single filtration method)> The water supply operation at the second drain level is shown in the flowchart of Fig. 16B, which has already been described for the drain operation. Steps S23 to S34 are the same as those in Fig. 16A, so their description will be omitted.

[0112] <First drainage level water supply operation (centralized filtration method)> The water supply operation at the first drain level is shown in the flowchart of Figure 16C, which has already been described in the drain operation. After opening the first valve body 41 in step S22, the valve body 75 (water supply valve body) is opened (S3), and then the valve body 72 is closed (S4). This enables water to be supplied from the filtered water tank 7 to each water tank 1. Note that steps S3 and S4 may be performed simultaneously. Steps S23 to S34 after step S4 are the same as those in Figures 16A and 16B, so their description will be omitted.

[0113] <Second drainage level water supply operation (centralized filtration method)> The water supply operation at the second drain level is shown in the flowchart of Figure 16D, which has already been described in the drain operation. Steps S1 and S2 are the same as those in Figure 16C. Steps S11 to S22 are the same as those in Figure 16B. Steps S3 and S4, and steps S23 to S34 are the same as those in Figure 16C. Therefore, their explanations will be omitted. Water supply to the filtered water tank 7 can be started by pressing the filtered water tank water supply button 412.

[0114] <Another embodiment of the water supply operation termination> The end of the water supply operation may be detected, for example, based on a sensor provided in the recovery pipe 68 shown in Figure 9. That is, as water continues to be supplied to the water tank 1, overflow water will enter through the opening 3a of the overflow pipe 3, and the end of water supply can be detected by detecting the amount of water. Alternatively, the end can be detected based on the time since the start of water supply, or by providing a float valve in each water tank 1.

[0115] When the supply of water to each water tank 1 is completed, tap water is supplied to the water storage tank 6 as described above, but when the tank is full, a configuration may be adopted in which the float valve 6a closes the valve body 66.

[0116] The valve bodies installed at each location in this embodiment are configured by, for example, solenoid valves, which can be automatically controlled to close and open based on command signals.

[0117] In this embodiment, the draining operation of the water tank 1 is controlled for each stage. When all stages are selected in the case of the single filtration method, draining and supplying water alternately from the top stage in the order of top stage → middle stage → bottom stage. In other words, after draining and supplying water to the top stage is completed, supplying and draining water to the middle stage is carried out. Finally, water is supplied to the water storage tank 6. When two stages are selected, such as the top and middle stages, supplying and draining water is carried out from the top stage in the same way.

[0118] In this embodiment, the configuration is such that individual aquariums 1 cannot be selected, but a system configuration may be adopted in which individual aquariums 1 can be selected.

[0119] In the case of a centralized filtration system, if all stages are selected, the water is drained in the order of the upper stage, middle stage, and lower stage. Then, water is supplied to the filtration tank 7 and the water storage tank 6. Even if two stages are selected, the water is drained from the upper stage.

[0120] It is also possible to prevent water changes in a specific aquarium 1. For this reason, by making it possible to close one-way cock 43 for each aquarium, drainage can be stopped while maintaining the air pressure inside cylindrical portion 30. Furthermore, for aquariums 1 that are not to be drained, water supply valve 65 is also closed to prevent water supply. One-way cock 43 may be closed manually, or a solenoid valve may be used instead of one-way cock 43, and automatic control by control unit 100 may be possible.

[0121] <Another embodiment> In this embodiment, an example in which multiple fixtures are installed has been described, but the fixture control and monitoring system according to the present invention can also be configured for a single fixture. In addition, the number of fixtures installed can be increased or decreased depending on the store's needs.

[0122] The master device (master unit) is provided on the fixture 100, but the location where it is installed relative to the fixture 100 can be determined in consideration of the convenience of the worker. It can also be freely determined whether or not it is installed directly on the fixture.

[0123] The concept of water supply and drainage control for the water tank includes not only control of water supply and drainage to the water tank 1, but also control of either water supply or drainage. Furthermore, water supply to the water tank 1 includes not only direct water supply to the water tank 1, but also water supply to the water storage tank 6 for supplying water to the water tank.

[0124] The drainage level selection unit 404 is configured to allow selection of two drainage levels, but may be configured to allow selection of three or more drainage levels.

[0125] In this embodiment, the lights are turned on and off collectively, but it is also possible to selectively turn on / off fixtures or aquariums. Also, each lighting unit may be provided with a switch so that it can be turned on and off individually.

[0126] In this embodiment, each aquarium is provided with both a water temperature sensor and a water quality sensor, but it may be provided with only one of them.

[0127] In this embodiment, the operation device A is configured with an operation panel 400 and a wireless connection device 500 (operated via a web screen), but the system may be configured with only the operation panel 400 as the operation device A, or may be configured with only the wireless connection device 500 (web screen). Also, the connection with the master unit 200 may be wireless or wired. [Explanation of symbols]
