  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a schematic configuration of a pumped water management system 10 according to an embodiment. As shown in this figure, the pumping management system 10 according to the present embodiment is a system that manages a plurality of pumping wells (deep wells) DW1 to DW4 that are installed at the site of excavation work for the purpose of overburdening. .

The control panel 16 is a sequence control device having a power failure compensation function, and includes a control unit 17 that controls each unit of the pumped water management system 10. Further, the distribution board 18 is connected to the cubicle 12 via a distribution line, and power is supplied to the pumping pump 20 and the like through the distribution board 18.

  The distribution board 18, the energization detector 22, the water level meter 24, the flow meter 26, and the electromagnetic valve 28 are connected to the control unit 17 via a signal line, and measurement data, operation commands, etc. with the control unit 17.

The breaker 19 has a function of automatically turning it on again when the breaker 19 enters a shut-off state.

  The energization detector 22 is provided on a distribution line that connects the cubicle 12 and the distribution board 18, detects energization between the cubicle 12 and the distribution board 18, and transmits a detection signal to the control unit 17. . Further, the water level gauge 24 measures the water level of the pumping wells DW1 to DW4 and transmits the measured value to the control unit 17. Further, the flow meter 26 is provided in the drainage channel 21 for draining the water pumped in the pumping wells DW1 to DW4, measures the drainage flow rate in each drainage channel 21, and transmits the measured value to the control unit 17. . Further, the electromagnetic valve 28 is provided in each drainage channel 21 and controls the drainage flow rate of each drainage channel 21.

  In addition, the pumped water management system 10 includes a mail transmission system 50. As shown in FIG. 2, the mail transmission system 50 includes a management personal computer 52, an uninterruptible power supply 54, and a portable terminal 56. The management personal computer 52 is connected to the control unit 17 of the control panel 16 via the LAN cable 58. The uninterruptible power supply 54 is a power source for the management personal computer 52, and supplies power to the management personal computer 52 for a certain time even in the event of a power failure. Furthermore, the mobile terminal 56 is a mobile phone, a smartphone, or the like, and is connected to the management personal computer 52 through an Internet line. In the mail transmission system 50, an alarm, a recovery status, and various measurement information are transmitted from the management personal computer 52 to the mail address set in the portable terminal 56, and various measurement information is regularly transmitted in an emergency. .

  FIG. 3 is a flowchart showing a processing flow of the pumped water management system 10. As shown in this flowchart, during normal times, measurement data is transmitted from the water level meter 24 and the flow meter 26 to the control unit 17, and the control unit 17 determines whether or not the measurement value of the water level meter 24 is equal to or greater than a threshold value. Then, it is determined whether or not the measured value of the flow meter 26 is less than the threshold value, and whether or not an activation signal has been received from the standby power supply 14 (step 1). In step 1, when the activation signal is received from the standby power source 14, the process proceeds to step 10 and processing in the case of a power failure is executed (steps 10 to 17), and the activation signal is not received from the standby power source 14. When it is determined that the measured value of the water level meter 24 satisfies at least one of the conditions that the measured value of the water level meter 24 is equal to or greater than the threshold value and the measured value of the flow meter 26 is less than the threshold value, the process proceeds to step 20 in FIG. Processing in the case where an abnormality occurs is executed (steps 20 to 24 in FIG. 4 and steps 30 and 31 in FIG. 5).

  In the case of a power failure, first, the control unit 17 transmits a power failure notification signal to the management personal computer 52, and the management personal computer 52 transmits a mail notifying that "power failure has occurred" to the portable terminal 56 (step 10). . Next, the control unit 17 determines whether or not an energization detection signal is received from the energization detector 22 (step 11).

  In step 11, if the energization detection signal is not received from the energization detector 22, the power is not supplied from the standby power supply 14, so the control unit 17 restores the power to the management personal computer 52. The management personal computer 52 transmits a mail informing the mobile terminal 56 of “emergency power supply recovery response (no power supply)” (step 12). On the other hand, when the energization detection signal is received from the energization detector 22 in step 11, the control unit 17 transmits a drive signal to all the pumps 20 (step 13), and the measured value of the water level gauge 24 is a threshold value. It is determined for all the pumping wells DW1 to D4 whether or not the measured value of the flowmeter 26 is equal to or greater than a threshold value (step 14).

  If it is determined in step 14 that the measured value of the water level gauge 24 is less than the threshold value and the measured value of the flow meter 26 is greater than or equal to the threshold value for all the pumped wells DW1 to D4, Since the pump 20 is operating normally, the control unit 17 transmits a signal to notify the power recovery to the management personal computer 52, and the management personal computer 52 notifies the mobile terminal 56 of “normal monitoring”. A mail to be sent is transmitted (step 15). On the other hand, if it is determined in step 14 that the measured value of the water level gauge 24 is greater than or equal to the threshold value or the measured value of the flow meter 26 is less than the threshold value for some of the pumping wells DW1 to D4, go to step 16. If it is determined that the measured value of the water level gauge 24 is greater than or equal to the threshold value or the measured value of the flow meter 26 is less than the threshold value for all the pumping wells DW1 to D4, the process proceeds to step 17.

  In step 17, the control unit 17 transmits a signal notifying execution of the flow control to the management personal computer 52, and the management personal computer 52 transmits a mail informing the mobile terminal 56 of “emergency flow control correspondence”. Thereafter, processing for increasing the pumping amount of the pump 20 and the drainage flow rate of the drainage channel 21 is executed (steps 30 and 31 in FIG. 5). On the other hand, in step 17, the control unit 17 transmits a signal notifying the abnormality of the pump 20 to the management personal computer 52, and the management personal computer 52 notifies the portable terminal 56 of “emergency recovery response (pump abnormality)”. Send an email.

  On the other hand, as shown in FIG. 4, when an abnormality occurs in the pump 20, first, the control unit 17 transmits a signal for notifying the abnormality of the pump 20 to the management personal computer 52, The personal computer 52 transmits a mail notifying the “pump abnormality” to the portable terminal 56 (step 20). Here, when an abnormality occurs in the pumping pump 20, the breaker 19 of the distribution board 18 performs an automatic return operation after being in a cut-off state.

  Next, the control part 17 transmits a drive signal to the pumping pump 20 in which abnormality was discovered (step 21), and the measured value of the water level meter 24 is less than a threshold value, and the measured value of the flow meter 26 is a threshold value. It is determined whether or not this is the case (step 22). If it is determined in step 22 that the measured value of the water level meter 24 is less than the threshold value and the measured value of the flow meter 26 is greater than or equal to the threshold value, all the pumps 20 are operating normally. Therefore, the control unit 17 transmits a signal notifying that the pumping pump 20 is normal to the management personal computer 52, and the management personal computer 52 sends an email notifying the mobile terminal 56 of “normal monitoring”. Transmit (step 23). On the other hand, if it is determined in step 22 that the measured value of the water level gauge 24 is equal to or greater than the threshold value, or the measured value of the flow meter 26 is less than the threshold value, the process proceeds to step 24. In step 24, the control unit 17 transmits a signal notifying execution of flow control to the management personal computer 52, and the management personal computer 52 transmits a mail informing the mobile terminal 56 of “emergency flow control correspondence”. Thereafter, processing for increasing the pumping amount of the pump 20 and the drainage flow rate of the drainage channel 21 is executed (steps 30 and 31 in FIG. 5).

  FIG. 5 is a flowchart showing a flow of emergency flow control of the pumped water management system 10. First, the control part 17 transmits the control signal of full open to the electromagnetic valve 28 corresponding to the pumping wells DW1-DW4 with the normal pumping pump 20 (step 30). Next, the control part 17 transmits the control signal which maximizes the amount of pumping to the normal pumping pump 20 (step 32). That is, in the emergency flow rate control in the present system, the pumping amount of the drivable pumping pump 20 is increased in order to compensate for the shortage of the pumping amount due to any one of the plurality of pumping pumps 20 becoming inoperable.

  As described above, in the pumped water management system 10 according to the present embodiment, the control unit 17 determines whether or not the pumped pump 20 is operating with the standby power supply 14 as a power source when a commercial power supply fails, and the mail transmission system. In 50, the management personal computer 52 transmits the determination information to the portable terminal 56 by e-mail. In other words, when the commercial power supply fails when the worker is absent from the site, if the pumping pump 20 that should be operated by the standby power source 14 remains stopped, there is an abnormality in the portable terminal 56 of the person concerned at the site. An email is sent to inform you. Therefore, the person concerned on the spot can grasp the situation and can take a recovery action as soon as possible.

  Moreover, the control part 17 determines the operating state of the pumping pump 20 based on the presence or absence of electricity supply between the standby power supply 14 and the pumping pump 20, the pumping amount of the pumping pump 20, and the water level of the pumping wells DW1-4. Accordingly, it can be determined whether or not the pump 20 is operating normally, and the occurrence of board bulge can be suppressed.

  In the pumped water management system 10 according to the present embodiment, the control unit 17 determines whether or not the pumped water pump 20 is operating after the breaker 19 is shut off and turned on again. The personal computer 52 transmits the determination information to the portable terminal 56 by e-mail. In other words, when any of the plurality of pumps 20 is out of order when no worker is present at the site, a mail is sent to inform the mobile terminal 56 of the person concerned at the site of the abnormality. Therefore, the person concerned on the spot can grasp the situation and can take a recovery action as soon as possible.

  Moreover, the control part 17 increases the amount of pumping by the pumping pump 20 which can be actuated, when it determines with any of the some pumping pump 20 being abnormal. As a result, when any of the plurality of pumps 20 is out of order when no worker is present at the site, the shortage of the pumped amount can be compensated until the person concerned at the site responds to recovery. You can delay my progress.

  In addition, the above-mentioned embodiment is for making an understanding of this invention easy, and does not limit this invention. It goes without saying that the present invention can be changed and improved without departing from the gist thereof, and that the present invention includes equivalents thereof. For example, in the above-described embodiment, the automatic return type breaker 19 is provided in the distribution board 18 so that it is automatically turned on again after being shut off. However, when the breaker 19 is shut off, the shut-off information is transmitted to the portable terminal 56 and the portable When a reintroduction signal is transmitted from the terminal 56 to the control unit 17, the control unit 17 may reinject the breaker 19.

  Moreover, in the above-mentioned embodiment, although mail was transmitted at the time of a power failure occurrence, you may make it transmit mail only after confirming the action | operation of the pump 20 after a power failure generate | occur | produces. Further, the mail is transmitted immediately after the abnormality of the pump 20 is detected, but the mail may be transmitted only after the pump 20 that has an abnormality is driven. Moreover, the method of transmitting the determination information of the operating state of the pump 20 to the receiving terminal is not limited to e-mail, and may be performed through a dedicated application.

  Furthermore, in the above-described embodiment, the operation state of the pumping pump 20 is determined based on all items of the energized state, the pumping amount of the pumping pump 20, and the water levels of the pumping wells DW1 to DW4. It may be determined based on one.
