Description

  The present invention relates to an aquarium system.

  Conventionally, in condominiums, etc., there is a water supply facility that temporarily stores water in a water tank installed on the rooftop, etc., and supplies water to each room from this water tank, and the seismometer connected to this water supply facility detects shaking due to an earthquake. Then, in order to secure water in case of a disaster, the valve (emergency shutoff valve) attached to the water tank was closed to stop water supply.

  In addition, as shown in FIG. 14, a water tank system including a local terminal 101, a pump 102, a water tank 103 with a shut-off valve, and a sensor 104 that detects the state of a water supply path is installed in the apartment. Some terminals 101 are connected to the monitoring server SV100 of the center via a network NT such as the Internet. The local terminal 101 controls the operation of the shutoff valves of the pump 102 and the water tank 103, and the pump 102 is supplied to the water tank 103. Thus, water is supplied to each room through a shut-off valve provided in the water tank 103.

If a disaster such as an earthquake occurs and the local terminal 101 determines that an abnormality has occurred in the water supply path based on the detection result of the sensor 104, the local terminal 101 closes the shut-off valve and stops water supply. An abnormal signal is transmitted from the terminal 101 to the center monitoring server SV100, and the center manager H1 remotely operates the shutoff valve (see, for example, Patent Document 1).
JP 2002-30702 A

  However, in the above-mentioned conventional technology, an earthquake arrives at the installation location of the system, and the seismometer installed in the system senses the actual shaking to control the shutoff valve, or a failure occurs in the water supply path after the earthquake occurs. After that, it was designed to prevent the outflow of water from the water tank by controlling the shutoff valve. For this reason, there will be a time lag between the actual occurrence of an earthquake shake and the closing of the shutoff valve, during which time water will flow out of the aquarium, buildings will be destroyed by the earthquake, and lifelines and communications will be blocked. As a result, there was a problem that water could not be stored in the tank and water could not be secured after the earthquake occurred.

  This invention is made | formed in view of the said reason, The objective is to provide the aquarium system which can ensure the water after an earthquake occurrence reliably.

  The invention of claim 1 is a water tank that is connected to a pipe and supplies the stored water to the user through the pipe, a pump that supplies the water to the water tank, and a shutoff valve that controls the amount of water flowing from the water tank to the pipe. , Equipped with a full water detection means for detecting the full state of the aquarium, an earthquake information acquisition unit for acquiring earthquake information generated by detecting initial microtremors, and a control unit for controlling the operation of the pump and shutoff valve The operation mode includes a normal control mode for performing operations when the earthquake information acquisition unit has not acquired earthquake information, and a full water control mode for performing operations when the earthquake information acquisition unit has acquired earthquake information. In the full water control mode, the shutoff valve is controlled to shut off the water flowing from the water tank to the pipe, and the pump is operated to supply water to the water tank. When the full water detection means detects the full water condition, the pump operation is stopped. The And wherein the Rukoto.

  According to the present invention, when initial tremor is detected with relatively little damage caused by an earthquake, the shutoff valve prevents the outflow of water from the aquarium, and the pump is operated to store water in the aquarium. Even if a major movement arrives and a building or lifeline is destroyed, water can be reliably secured after the earthquake occurs.

  The invention of claim 2 comprises a communication unit that transmits a full water warning via a network when the full water detection unit detects a full water state in claim 1, and the control unit is a full water detection unit in the full water control mode. When a full water condition is detected, the transmission operation of the full water alarm from the communication unit is stopped.

  According to the present invention, when an earthquake occurs, it is possible to suppress an increase in network communication traffic, and it is possible to prevent a false alarm of a full water warning.

  The invention of claim 3 comprises, in claim 2, an earthquake sensor for detecting the occurrence of a surrounding earthquake and an inspection means for inspecting the presence or absence of damage to the aquarium system, wherein the control unit is in a full water control mode. If it is determined that the shaking of the earthquake has been settled based on the detection result of the earthquake sensor and it is determined that there is no damage based on the inspection result of the inspection means, the full water control mode is shifted to the normal control mode.

  According to the present invention, after the earthquake has stopped, the state in which the water in the aquarium cannot be used automatically can be resolved, and the water supply can be resumed quickly, so that the user can use the water after the earthquake. No state can be shortened.

  The invention of claim 4 is characterized in that, in claim 3, the control unit controls the shut-off valve when shifting from the full water control mode to the normal control mode, and discharges water in the water tank from the pipe. To do.

  According to the present invention, it is possible to avoid a state in which a full water warning is likely to occur when returning to the normal control mode.

  The invention of claim 5 comprises the storage unit according to any one of claims 1 to 4, further comprising a storage unit that stores a residual water amount necessary for filling the aquarium when the earthquake information acquisition unit acquires earthquake information. The unit constitutes a full water detecting means for detecting the full water state of the aquarium when it is determined that the remaining water amount is supplied based on the flow rate of water that can be supplied by the pump and the operation time of the pump during the full water operation mode. The operation of the pump is stopped when the full water detection means detects a full water state.

  According to the present invention, in the full water detection means that generally detects the water level in the aquarium using a mechanism such as an electrode rod or water pressure, the water surface in the aquarium shakes and the detection accuracy deteriorates when an earthquake occurs. Even if the information is received and the operation mode is changed from the steady operation mode to the full water operation mode, there is a possibility that the water cannot be stored up to the full water accurately. By doing so, even if the water surface in the aquarium shakes due to an earthquake, it is possible to store water up to full water accurately.

  The invention of claim 6 provides the maximum water storage amount that can be stored in the water tank, and the first water amount that is stored in the water tank when the earthquake information acquisition unit acquires earthquake information. And a water amount sensor that measures a flow rate of water supplied by the pump, and the control unit adds a measurement result of the water amount sensor to the first water amount in a full water operation mode. Comparing the amount of water with the maximum amount of water stored, a full water detection means is configured to detect when the second water amount reaches the maximum amount of water stored, and when the full water detection means detects a full water state, The operation is stopped.

  According to this invention, since the pump determines full water based on the actual flow rate of water supplied to the water tank, even when the pump is fully operated due to damage to the lifeline or the like, even if the maximum flow rate is not reached. Can store up to exactly full water.

  As described above, according to the present invention, even when a building, a lifeline, or the like is destroyed by an earthquake, there is an effect that water can be reliably secured after the earthquake occurs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
In recent years, by using emergency earthquake bulletins, etc., it is possible to use the difference in transmission speed between the initial tremor (hereinafter referred to as P wave) and the main motion (hereinafter referred to as S wave) unless it is a direct earthquake. Earthquake information can be obtained before the arrival of the S wave. This seismic information, when a seismometer installed near the epicenter detects the occurrence of P waves, immediately analyzes the epicenter and magnitude of the earthquake, and based on this, estimates the arrival time and seismic intensity of S waves in each location. And it is notified to each place.

  The present invention is a water tank system using this earthquake information, and FIG. 1 shows the configuration of this embodiment. The aquarium system is installed in a condominium or the like, and is composed of a control unit 1, a pump 2, a water tank 3, a shut-off valve 4, and an earthquake information acquisition unit 5. The water tank 3 detects the water level in the water tank 3. A water level sensor 3a for outputting a water level signal is provided.

  The control unit 1 controls the operation of the pump 2 and the shutoff valve 4. Normally, by operating the pump 2, water is supplied to the water tank 3 through the pipe P <b> 1 to open the shutoff valve 4. Thus, the water stored in the water tank 3 is supplied to each room via the pipe P2, and when it is determined that the water tank 3 is full based on the water level signal from the water level sensor 3a, the operation of the pump 2 is stopped. Operates in steady control mode. The earthquake information acquisition unit 5 is connected to the management server SV1 of the center via a network NT such as the Internet, and is configured to be able to communicate with the management server SV1.

  The management server SV1 is connected to the earthquake information server SV2 via a network (Internet, dedicated network, etc.), and the earthquake information server SV2 detects that a seismometer installed near the epicenter detects the occurrence of a P wave. , Immediately analyze the epicenter and magnitude of the earthquake, and transmit earthquake information such as the arrival time and seismic intensity of S waves in each place when an earthquake occurs. The management server SV1 transmits the earthquake information received from the earthquake information server SV2 via the network NT, and the earthquake information acquisition unit 5 acquires the earthquake information at the installation location of the system.

  Hereinafter, the operation at the time of earthquake information acquisition will be described with reference to the flowchart of FIG. First, when the earthquake information acquisition unit 5 acquires earthquake information (step S1), the control unit 1 shifts from the steady control mode to the full operation mode (step S2), closes the shut-off valve 4 (step S3), and further The pump 2 is fully operated, and water is introduced at the maximum flow rate until it is determined that the water tank 3 is full based on the water level signal from the water level sensor 3a (step S4). Therefore, when a P wave that is relatively damaged by an earthquake is detected, the shutoff valve 4 is closed to prevent the outflow of water from the water tank 3, and the pump 2 is fully operated to store water in the water tank 3. . Therefore, even when an S wave with large shaking arrives and a building, a lifeline, or the like is destroyed, it is possible to reliably secure water after the earthquake occurs.

  After the earthquake has stopped and the damage situation has been confirmed, the control unit 1 is changed from the full operation mode to the steady control mode by an operation of an operation unit (not shown) provided in the control unit 1 or an instruction signal from the management server SV. Then, the shutoff valve 4 is opened to resume water supply from the water tank 3 to each room, and the pump 2 is operated as necessary.

(Embodiment 2)
As shown in FIG. 3, the aquarium system of the present embodiment is provided with a communication unit 6 in the configuration of the first embodiment, and the communication unit 6 communicates with the management server SV1 via the network NT. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.

  The control unit 1 determines whether the water level is full based on the water level signal from the water level sensor 3a, and transmits a full water warning from the communication unit 6 to the management server SV1 via the network NT when the water level is full. The management server SV1 that has received the full water warning notifies the manager H1 of the warning and prompts the manager H1 to pay attention.

  However, when the earthquake occurs, the communication traffic of the network NT increases in various places, and it is not preferable to transmit a full water warning to the management server SV1 even in the full water operation mode because the communication traffic further increases. Moreover, since the water surface in the aquarium 3 is also shaken due to the shaking of the earthquake, it is conceivable that the water level sensor 3a erroneously detects the full water and the false alarm of the full water warning occurs.

  Therefore, in this embodiment, as shown in the flowchart of FIG. 4, when the earthquake information is received and the normal control mode is shifted to the full water operation mode, the control unit 1 closes the shut-off valve 4 and pumps in steps S1 to S4. 2 is fully operated, the water is stored in the water tank 3, and the operation of transmitting the full water alarm from the communication unit 6 is stopped (step S5). When the water tank 3 is determined to be full based on the water level signal from the water level sensor 3a, the operation of the pump 2 is stopped. (Step S6).

  Therefore, a full water warning is not transmitted in the full water operation mode, and an increase in communication traffic of the network NT can be suppressed when an earthquake occurs, and further a false alarm of a full water alarm can be prevented.

(Embodiment 3)
Because it is the same as the water outage from the user's point of view, the shutoff valve 4 is closed and the water supply is stopped and the water tank 3 is kept full in a situation where it can be determined that the earthquake has stopped and there is no damage. It becomes a problem. In the first and second embodiments, whether or not to resume water supply after an earthquake (transition from the full operation mode to the steady control mode) is determined by human judgment, but in this embodiment, after an earthquake automatically as follows Judge whether or not to resume water supply.

  As shown in FIG. 5, the aquarium system of the present embodiment includes an earthquake sensor unit 7 and a device inspection unit 8 in the configuration of the second embodiment. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 2, and description is abbreviate | omitted.

  The seismic sensor unit 7 detects the seismic intensity around the installation location of the system and outputs a seismic intensity signal, and this seismic intensity signal is input to the control unit 1 via the earthquake information acquisition unit 7.

  The apparatus inspection unit 8 has a function of inspecting the pipe P2 for breakage in the apartment building, and determines whether or not the pipe is broken based on, for example, water pressure.

  And after the earthquake information acquisition part 5 acquires earthquake information and performs the process of step S1-S6 of Embodiment 2 (step S11) as shown to the flowchart of FIG. 6, the control part 1 is the present mode. Is determined to be in the full operation mode (step S12). If the control unit 1 is in the steady control mode, the process is terminated. If it is in the full operation mode, the control unit 1 determines whether an earthquake shake is detected based on the seismic intensity signal from the earthquake sensor unit 7 (step 13). If the earthquake shake is being detected, the process is terminated. If the earthquake shake is not detected, it is determined that the earthquake shake has stopped, and the pump 2 is operated (step S14). That is, the pump 2 is restarted for a predetermined time if the shaking of the earthquake stops in the full water operation mode.

  Then, when water is put into the water tank 3 by the pump 2, the control unit 1 determines whether or not a flow rate corresponding to the output of the pump 2 is supplied by a water level signal from the water level sensor 3a (or a water amount sensor not shown). Determination is made based on the measured amount of supplied water (step S15). When the flow rate is smaller than the output of the pump 2, it is considered that the lifeline side or the pump 2 or the pipe P1 is damaged, and thus this processing is terminated.

  When the flow rate corresponding to the output of the pump 2 is supplied, the apparatus inspection unit 8 next inspects the piping P2 in the apartment building for damage (step S16). Since it is considered that the pipe P2 is broken, this process is terminated.

  And when it determines with there being neither damage in step S15, S16, the control part 1 transfers to a steady operation mode from a full operation mode (step S17), opens the shut-off valve 4, and removes from the water tank 3. Water supply is resumed (step S18).

  Therefore, after the earthquake has stopped, the state in which the water in the tank 3 can not be used automatically can be resolved, and the water supply can be restarted quickly, so that the user cannot use the water after the earthquake. Can be shortened.

(Embodiment 4)
In the third embodiment, when the full water operation mode is changed to the steady control mode and the water supply from the water tank 3 is resumed, the full water alarm transmission stop state from the communication unit 6 is also canceled at the same time the normal control mode is entered. If the water tank 3 is in a full water state due to the full water operation mode, a full water warning is transmitted from the communication unit 6 to the management server SV1.

  Therefore, in this embodiment, in the water tank system shown in FIG. 5 as in the third embodiment, the full water alarm transmission stop state is canceled according to the flowchart of FIG. First, in steps S11 to S18, the control unit 1 shifts from the full water operation mode to the steady operation mode, opens the shutoff valve 4, and resumes water supply from the water tank 3 in the same manner as in the third embodiment. At this time, the transmission stop state of the full water warning is still maintained.

  And the control part 1 determines whether it is full based on the water level signal from the water level sensor 3a (step S19), and repeats step S19 until the water of the water tank 3 decreases and a full water state is cancelled | released. . When the full water state is canceled, the control unit 1 cancels the transmission stop state of the full water alarm from the communication unit 6 (step S20).

(Embodiment 5)
In the first to fourth embodiments, the controller 1 determines whether or not the water tank 3 is full based on the water level signal from the water level sensor 3a, and operates the pump 2 until the water tank 3 is full. Add water until However, the water level sensor 3a generally detects the water level in the aquarium 3 using a mechanism such as an electrode rod or water pressure, and when the earthquake occurs, the water level in the aquarium 3 is shaken and the detection accuracy is deteriorated. Therefore, even if earthquake information is received and a transition is made from the steady operation mode to the full water operation mode, there is a possibility that water cannot be stored up to full water accurately.

  Therefore, as shown in FIG. 8, the water tank system of the present embodiment is provided with the storage unit 9 in the configuration of the third or fourth embodiment. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 3 or 4, and description is abbreviate | omitted.

  When the earthquake information acquisition unit 5 acquires the earthquake information, the control unit 1 stores the remaining water amount (residual water amount information) necessary to fill the water tank 3 in the storage unit 9. The storage unit 9 stores the remaining water amount information by acquiring a water level signal from the water level sensor 3a when the control unit 1 acquires the earthquake information, and the remaining water amount based on the water level signal. A method for storing information in the storage unit 9 and a water level signal from the water level sensor 3a are always acquired at regular intervals, and the remaining water amount information based on the latest water level signal before earthquake information acquisition is stored in the storage unit 9. There is a way to do it.

  As shown in the flowchart of FIG. 9, when the earthquake information acquisition unit 5 acquires the earthquake information (step S31), the control unit 1 shifts from the steady control mode to the full operation mode (step S32), and the shut-off valve 4 is closed (step S33), and the pump 2 is fully operated, and water is poured at the maximum flow rate Qm until the water tank 3 is full (step S34).

  At this time, in this embodiment, when the control unit 1 is fully operating, the remaining water amount information stored in the storage unit 9 is the water injection time T1 required until the current water level becomes full. And the maximum flow rate Qm, and the water injection time T1 is stored in the storage unit 9. And the control part 1 operates the pump 2 fully only for the water injection time T1 stored in the memory | storage part 9 (refer FIG. 10). The water injection time T1 is obtained by using a calculation formula stored in advance in the storage unit 9 or a table in which the remaining water amount information and the calculation time are associated with each other in advance. There is a way to refer to.

  And the control part 1 stops the transmission operation | movement of the full water warning from the communication part 6 (step S35), judges that the water level of the water tank 3 reached the full water level when the water injection time T1 passed, and the pump 2 Stop the operation. (Step S36).

  In this way, the full water level is not determined based on the water level of the water tank 3 by the water level sensor 3a, but the maximum flow rate Qm of the pump 2 is continued for the water injection time T1, so that the remaining water amount is supplied to the water tank 3 and becomes full. Therefore, even when the water surface in the aquarium 3 shakes due to an earthquake, it is possible to store water up to full water accurately.

(Embodiment 6)
In the configuration of the fifth embodiment, it is assumed that the water fill is determined by using the water injection time T1 at the maximum flow rate Qm of the pump 2, and that the water amount of the water pipe as a lifeline can be used 100%. However, when an actual earthquake occurs, depending on the situation such as the water pipes around the apartment being damaged, even if the pump 2 is fully operated, the maximum flow rate Qm may not be reached. There is a possibility that the water tank 3 does not become full even when the water is put into the water tank 3 for the time T1.

  Therefore, as shown in FIG. 11, the water tank system of the present embodiment is provided with the storage unit 10 and the water amount sensor 11 in the configuration of the fifth embodiment. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 5, and description is abbreviate | omitted.

  The storage unit 10 stores in advance information on the maximum amount of water that can be stored in the water tank 3. The maximum water storage amount is determined by the size and shape of the water tank 3.

  The water amount sensor 11 measures the flow rate of water supplied to the water tank 3 by the pump 2 via the pipe P1, and sequentially stores the flow rate signal in the storage unit 9 as the measurement result.

  Then, as shown in the flowchart of FIG. 12, when the earthquake information acquisition unit 5 acquires the earthquake information (step S41), the control unit 1 shifts from the steady control mode to the full operation mode (step S42), and the shut-off valve 4 is closed (step S43), and the full water warning transmission operation from the communication unit 6 is stopped (step S44).

  Next, the control unit 1 calculates the current water amount (first water amount) stored in the water tank 3 based on the water level signal of the water level sensor 3a, and stores it in the storage unit 9 as the current water amount L (step S45). ). In FIG. 12, it is assumed that the current water amount L = 0 (the water tank 3 is empty).

  And the control part 1 puts the water in the water tank 3 by operating the pump 2 fully for 1 minute (step S46). The flow rate signal from the water amount sensor 11 is sequentially stored in the storage unit 9 even during this one minute water injection, and the control unit 1 calculates the amount M of water supplied to the water tank 3b by this one minute water injection, The supplied water amount M is added to the current water amount L stored in the storage unit 9, and this addition result is stored in the storage unit 9 as the current water amount L (second water amount) (step S47). Is compared with the maximum water storage amount stored in the storage unit 10 (step S48).

  If the current water amount L is less than or equal to the maximum water storage amount, the control unit 1 returns to step S46 to fully operate the pump 2 for another one minute and put water into the water tank 3. On the other hand, if the current water volume L exceeds the maximum water storage volume, it is determined that the water level in the water tank 3 has reached the full water level, and the operation of the pump 2 is stopped. (Step S49). An example of the flow rate of water supplied from the pump 2 at this time (flow rate information output from the water amount sensor 11) is shown in FIG.

  Thus, since the pump 2 determines that the water is full based on the actual flow rate of water supplied to the water tank 3, even when the pump 2 is fully operated due to damage to the lifeline, the maximum flow rate Qm is not reached. But you can store up to full water accurately.
