  Below, the control apparatus of the manhole pump apparatus by this invention, the manhole pump apparatus, and the operating method of a manhole pump apparatus are demonstrated. As shown in FIG. 1, the manhole pump device 10 includes a manhole 12 that stores water such as sewage and rainwater that flows in from the inflow pipe 11a, a pump 13 that pumps the water stored in the manhole 12 to the outflow pipe 11b, A water level meter 14 that measures the water level of water stored in the manhole 12 and a control device 20 that controls the pump 13 based on a signal from the water level meter 14 are provided.

  The control device 20 is incorporated in a control panel housed in a control panel device 200 provided in the vicinity of the manhole pump device 10.

  The manhole pump device 10 is provided with two pumps 13 for failure or maintenance, and is normally set to alternately operate.

  The water level gauge 14 is an injection pressure type or bubble type water level gauge, and is installed at the bottom of the manhole 12 so as to continuously detect the water level stored in the manhole 12. Further, in preparation for failure of the water level gauge 14, a float type water level gauge 15 for backup is installed at a height that causes an abnormally high water level, and the water level gauge 14 and the water level gauge 15 are configured to detect the abnormal high water level. .

  As shown in FIG. 2, the control device 20 includes a control unit 21 and a communication unit 22.

  The control unit 21 is measured by a CPU (not shown), a ROM storing various control programs such as start control and stop control of the pump 13 executed by the CPU, a RAM used as a working area, and a water level gauge 14. An input / output circuit for inputting control information such as a water level and a pump failure signal and outputting a control signal for starting the pump is provided.

  When the water level gauge 14 detects that the water level in the manhole 12 has risen to a predetermined starting water level HWL, the control unit 21 outputs a starting signal and starts the pump 13, and the water level in the manhole 12 reaches the predetermined storage lower end water level. When the water level gauge 14 detects that the water level has fallen to LWL, it is configured to output a stop signal after being driven for a predetermined time by a timer provided therein, and to stop the operation of the pump 13 at the stop water level LLWL.

  Therefore, when the water level in the manhole 12 reaches the pump start water level HWL and starts, the pump 13 is pumped to the outflow pipe 11b until the water level reaches the stop water level LLWL. Further, the operation of the pump 13 may be stopped when the water level gauge 14 detects that the water level in the manhole 12 has decreased to the predetermined storage lower water level LWL or the stop water level LLWL without using a timer. Good.

  However, if the amount of water flowing into the manhole 12 per unit time is greater than the amount of water stored in the manhole 12 by the pump 13 per unit time, the water level will rise even if the pump 13 is started. Since the water may overflow from the manhole 12, an abnormally high water level HHWL is provided, and the control unit 21 indicates that the water level in the manhole 12 has reached the abnormally high water level HHWL. When detected by the total 15, an abnormality occurrence signal is output to the communication unit 22.

  As shown in FIG. 3, the communication unit 22 provided in the control device 20 of the manhole pump device 10 includes a communication unit provided in the upstream manhole pump device 40 and the downstream manhole pump device 50, or each manhole pump. Control information such as operation / stop and operation time of the pump 13 controlled by the control unit 21, operation status such as occurrence of failure, and occurrence of abnormal water level with an external device such as a management center 52 that centrally manages the device Is configured to transmit and receive.

  The communication unit 22 can be configured by a communication terminal corresponding to a public line network such as a data line network, a mobile phone network, and a general telephone line network, or a local communication medium such as a small area radio.

  In FIG. 3, communication between the manhole devices 40 and 50 is performed by a communication terminal for the low-power wireless network 54, and a manhole pump device in which a communication terminal that supervises control information obtained through each communication terminal is installed. 10, a communication device for communicating with an external device is installed. The communication apparatus is configured by a communication apparatus for the mobile phone network 55 and an example in which communication with the management center 52 is performed via the base station 53 is shown.

  The management center 52 centrally manages the operation status of each manhole pump device 10, 40, 50 installed in each area, and when an accident such as a failure or overflow is detected, it reports to the nearest management office. It is configured.

  Based on the control information of the upstream manhole pump device 40 received by the communication unit 22, the control unit 21 detects that the pump included in the upstream manhole pump device 40 is activated, and the water level gauge 14 When the predicted water level VL calculated based on the detected water level PL and the amount of water that is expected to flow in by the upstream pump being started becomes equal to or higher than the pump starting water level HWL, the water level lower than the pump starting water level HWL Is configured to start the pump 13.

  That is, based on the control information of the manhole pump device 40 adjacent to the upstream side, when the predicted water level that rises by flowing from the upstream pump becomes equal to or higher than the pump activation water level HWL, that is, the manhole pump device 40 The water level rise amount of the manhole pump device 10 due to the flow of water corresponding to the volume between the pump start water level and the stop water level is calculated, and the predicted water level obtained by adding this water level rise amount to the detected water level PL is equal to or higher than the pump start water level HWL. At this time, the storage capacity in the downstream manhole 12 can be substantially increased by starting the downstream pump 13 in advance and discharging the water stored in the manhole 12.

  Therefore, when the actual inflow amount is larger than the assumed inflow amount of water from a nearby residence or the like, which is a design value at the time of installing the manhole pump device 12, and the storage capacity of the downstream manhole 12 is not sufficient, Even when the discharge amount of the pump 13 on the side is not sufficient or when the inflow amount of water that suddenly increases the inflow amount of rainwater such as torrential rain, the occurrence of abnormally high water levels and the sewage from the manhole 12 It is possible to reduce the possibility of overflow of rainwater or the like.

  The start-up control and operation method of the manhole pump device 10 according to the present invention will be described based on the flowcharts shown in FIGS.

  First, the water level PL flowing into and stored in the manhole 12 from the upstream manhole pump device 40 and the neighboring residence 60 through the inflow pipe 11a is continuously detected by the water level gauge 14 (SA1), and the control unit 21 Determines whether the water level PL has reached a predetermined pump activation water level HWL (SA2).

  If the water level PL has reached the predetermined pump activation water level HWL (SA2; YES), the control unit 21 activates the pump 13 (SA3), and pumps the water stored in the manhole 12 to the outflow pipe 11b.

  Even when the water level PL has not reached the predetermined pump activation water level HWL (SA2; NO), when the communication unit 22 receives the activation control information of the pump 43 of the upstream manhole pump device 40 (SA4; YES) The predicted water level VL is calculated based on the detected water level by the water level gauge 14 and the amount of water that is expected to flow in by the upstream pump 43 being activated, that is, the amount of water delivered by the pump 43 (SA5). ) When the predicted water level VL is equal to or higher than the pump activation water level HWL (SA6; YES), the pump 13 is activated at a water level lower than the pump activation water level HWL (SA3). If the calculated predicted water level VL has not reached the pump activation water level HWL (SA6; NO), the pump 13 is not activated. Note that the order of step SA4 and step SA5 is not limited to the above, and step SA4 may be performed after step SA5.

  Next, stop control of the pump 13 of the manhole pump apparatus 10 will be described based on the flowchart shown in FIG.

  The water level meter 14 continuously detects the water level of the water flowing in from the inflow pipe 11a stored in the manhole 12 (SB1) and inputs it to the control unit 21. The control unit 21 determines whether or not the water level detected by the water level gauge 14 has reached a predetermined storage lower end water level LWL (SB2).

  If the water level detected by the water level gauge 14 has reached a predetermined storage lower end water level LWL (SC2; YES), the controller 21 sets a timer for a predetermined time (SB3), and when the timer counts up (SB4; YES) ), And the pump 13 is stopped (SB5).

  Hereinafter, another embodiment of the control device of the manhole pump device, the manhole pump device and the operation method of the manhole pump device according to the present invention will be described.

  When the rising speed v1 of the water level PL calculated by the control unit 21 is equal to or higher than a preset first threshold, or based on the control information of the upstream manhole pump device 40 received by the communication unit 22 When it is detected that the water level rising speed v2 of the manhole pump device 40 is equal to or higher than a preset second threshold value, or when both are satisfied at the same time, the control unit 21 activates the upstream pump 43. The predicted water level VL is calculated based on the detected water level PL detected by the water level gauge 14 and the amount of water predicted to flow in from the upstream pump 43, and the predicted water level VL is equal to or higher than the pump activation water level HWL. When it becomes, you may control to start the pump 13 in the water level lower than the pump starting water level HWL.

  When the rising speed v1 of the water level PL is calculated and the rising speed v1 is equal to or higher than the first threshold value, the inflow of water such as rainwater suddenly increases due to torrential rain or the like, or flows into the manhole pump device 10 The pump 13 is activated at a water level lower than the activation water level HWL by determining that the amount of water from a neighboring residence or the like is greater than the assumed amount of water.

  Similarly, when the upstream water level rising speed v2 is equal to or higher than the second threshold, the amount of water flowing into the upstream manhole pump device 40 increases, and the water flowing into the downstream manhole pump device 10 flows. Since the amount can also be predicted to increase, in that case, the pump is started at a water level lower than a predetermined starting water level HWL.

  Further, the control unit 21 includes a time measuring unit 23, and the pump 13 at a water level lower than the above-described starting water level HWL on condition that the time measured by the time measuring unit 23 is included in a time zone set in advance on the control panel. You may comprise so that the control which starts may be performed.

  In residential areas, the amount of domestic wastewater increases in the morning and evening to nighttime, and in the factory area, the amount of drainage tends to decrease on holidays such as Saturdays, Sundays, and holidays, and the amount of wastewater increases on weekdays. In consideration of the regional characteristics, when the time measured by the time measuring unit 23 is included in the time zone, the pump 13 is activated at a lower water level than the above-described activation water level HWL when the upstream pump is activated. Control is executed.

  As described above, when the control for starting the pump 13 at a water level lower than the above-described starting water level HWL is executed in a time zone in which the inflow amount of water is expected to increase, the pump 13 is started unnecessarily at a low water level. While effectively suppressing deterioration of the pump due to heat generated by doing so, it is possible to avoid a situation of rising to an abnormal water level.

  Further, in order to take into account the increase or decrease in the amount of inflow of water such as sewage and rainwater due to seasonal fluctuations, the timing unit 23 determines the season and the like, and is set based on preset season information and past rainfall data. If the control for starting the pump 13 at a water level lower than the starting water level HWL described above is executed in a time zone in which the amount of water inflow is expected to increase based on the date and time data, the rainy season or the typhoon arrival time It becomes possible to cope with.

  An operation method of the pump 13 of the manhole pump apparatus 10 incorporating the above-described another embodiment will be described based on a flowchart shown in FIG.

  First, the water level PL is continuously detected by the water level gauge 14 (SC1), water from the upstream manhole pump device 40 and water stored in the manhole 12 from the neighboring residence 60 through the inflow pipe 11a. The control unit 21 calculates the water level rising speed v1 from the detected water level PL (SC2). Next, the control unit 21 determines whether or not the water level PL has reached a predetermined pump activation water level HWL (SC3).

  If the water level PL has reached the predetermined pump activation water level HWL (SC3; YES), the control unit 21 activates the pump 13 (SC4), and pumps the water stored in the manhole 12 to the outflow pipe 11b.

  When the water level PL has not reached the predetermined pump activation water level HWL (SC3; NO), the control unit 21 determines whether or not the current time measured by the time measuring unit 23 is included in a preset time zone. (SC5). If the time is set in advance and included in the time zone (SC5; YES), it is determined whether or not the calculated water level rising speed v1 is equal to or higher than the first threshold (SC6).

  When the water level rising speed v1 is equal to or higher than the first threshold (SC6; YES), the communication unit 22 controls the start control information of the pump 43 of the upstream manhole pump device 40 and the information about the water level rising speed v2 of the upstream manhole 42. Is received (SC7; YES), it is determined whether or not the water level rising speed v2 is greater than or equal to the second threshold (SC8). If the water level rising speed v2 is equal to or higher than the second threshold (SC8; YES), the predicted water level VL is based on the water level detected by the water level meter 14 and the amount of water that is expected to flow in by the upstream pump 43 being started. When the predicted water level VL is equal to or higher than the pump activation water level HWL (SC10; YES), the pump 13 is activated at a water level lower than the pump activation water level HWL (SC4).

  The control unit 21 does not include the time zone counted by the time measuring unit 23 in the preset time zone (SC5; NO), or even when the time zone is included in the preset time zone (SC5). YES), when the water level rising speed v1 of the manhole 12 does not reach the first threshold (SC6; NO), or even if the water level rising speed v1 of the manhole 12 is equal to or higher than the first threshold, the communication unit 22 is upstream If the start control information of the pump 43 of the manhole pump device 40 is not received (SC4; NO), or if the communication unit 22 receives the start control information of the pump 43 of the manhole pump device 40 on the upstream side (SC7; YES) ), Detected by a water level gauge 44 provided in the upstream manhole pump device 40, and incorporated in a control panel housed in a control panel device 300 provided in the vicinity of the manhole pump device 40. When the water level rise speed v2 calculated by the control device 30 that has not reached the second threshold value (SC8; NO), or even if the upstream water level rise speed v2 is greater than or equal to the second threshold value (SC8; YES), If the calculated predicted water level VL has not reached the pump activation water level HWL (SC10; NO), the pump 13 is not activated.

  In the flowchart shown in FIG. 7 described above, the judgment criteria at step SC7 are essential, but the judgment criteria at steps SC5, SC2 and SC6, SC8, SC9 and SC10 do not necessarily have to be provided. Any one or a plurality of determination criteria may be combined depending on conditions such as capacity, water inflow and discharge. The order is not limited to this.

  For example, the structure which combined the criterion by step SC2 and SC6, SC7, SC9, and SC10 may be sufficient. Accordingly, when the control unit 21 detects that the upstream pump 43 is activated based on the control information of the upstream manhole pump device 40 received by the communication unit 22, the water level detected by the water level gauge 14 is detected. The predicted water level VL is calculated based on PL and the amount of water that is expected to flow in by the upstream pump 43 being activated. When the predicted water level VL is equal to or higher than the pump activation water level HWL, the pump activation water level is calculated. On the premise of the configuration in which the pump 13 is started at a water level lower than the HWL, the control unit 21 performs when the water level rising speed v1 calculated based on the detected water level PL by the water level gauge 14 is equal to or higher than a preset first threshold value. The control device of the manhole pump device that starts the pump 13 at a water level lower than the pump starting water level HWL.

  Furthermore, the control unit 21 includes a timer unit 23 and a learning unit 24 that learns a time zone in which the pump is activated at a level lower than the pump activation water level. The controller 21 learns the time counted by the timer unit in the learning unit 24. It may be configured to execute any control for starting the pump 13 at a water level lower than the above-described starting water level HWL, on condition that it is included in the set time zone.

  The learning unit 24 accumulates and stores in the RAM the time and activation time when the pump 13 is activated at a level lower than the pump activation water level HWL, and performs statistical processing based on accumulated data within a predetermined period such as one week or one month. Learning the time zone and day of the week when the inflow increases.

  According to the above-described configuration, it is not necessary to set a time zone for performing control for starting the pump 13 at a water level lower than the startup water level HWL via the control panel.

  The learning control in the time zone when the pump 13 is started at a water level lower than the predetermined startup water level HWL by the control unit 21 will be described based on the flowchart shown in FIG.

  When the control unit 21 activates the pump 13 (SD1; YES), whether the water level in the manhole 12 reaches the pump activation water level HWL and the pump 13 is activated, or even if the pump activation water level HWL is not reached, the predicted water level is the pump activation water level. It is determined whether or not the pump 13 has been started because of HWL or more (SD2).

  When the pump 13 is activated at a level where the water level of the manhole 12 is lower than the predetermined pump activation water level HWL (SD2; YES), the learning unit 23 stores the activation time and the actual water level when activated.

  When the water level in the manhole 12 reaches the pump stop water level, the control unit 21 stops the pump 13 (SD4; YES). When the pump 13 stops (SD4; YES), the learning unit 23 stores the stop time and the actual water level when the pump 13 stops (SD5).

  The control unit 21 calculates the time zone when the pump 13 is started from the time when the pump 13 is started and stopped stored by the learning unit 23, and the pump 13 is calculated from the time and the water level when the pump 13 is started and stopped. The flow rate of the pumped water is calculated by starting (SD6), and the learning unit 23 stores the time zone and the flow rate (SD7).

  FIG. 8B shows the water level setting control for starting the pump 13 at a water level lower than the starting water level HWL based on the time zone when the pump 13 is started at a water level lower than the predetermined starting water level HWL by the learning control of the control unit 21. This will be described based on the flowchart shown in FIG.

  The control unit 21 determines whether or not the time counted by the time measuring unit 23 is included in the time zone learned by the learning unit 24 (SE1) when performing the start control of the pump 13. When included in the belt (SE1; YES), when the communication unit 22 receives the activation control information of the pump 43 of the upstream manhole pump device 40 (SE2; YES), the pump 13 is activated at a water level lower than the activation water level HWL. (SE3). Note that the amount of decrease in the startup water level is determined based on the flow rate stored in the learning unit 23.

  Moreover, the control part 21 is provided with the rain gauge which measures the rainfall in the installation location vicinity of the manhole pump apparatus 10, and the measured value of the rainfall per unit time by the said rain gauge is more than the preset 1st threshold value. And when it detects that the said upstream pump 43 is started based on the control information of the upstream manhole pump apparatus 40 received by the communication part 22, the pump 13 is made into the water level lower than the pump starting water level HWL. You may comprise so that it may start.

  Thereby, when the rainfall amount per unit time measured by the rain gauge provided in the control unit 21 is equal to or more than the first threshold value set in advance, it is determined that more water than normal flows in. In such a case, when it is detected that the upstream pump 43 is activated, the pump 13 is activated at a level lower than the pump activation level HWL, thereby generating an abnormally high water level or overflowing water from the manhole. Can be avoided in advance.

  Further, the control unit 21 receives the rainfall per unit time measured by the rain gauge provided in the upstream manhole pump device 40 based on the control information of the upstream manhole pump device 40 received by the communication unit 22. That the measured value is equal to or greater than a preset second threshold value and the upstream pump 43 is activated based on the control information of the upstream manhole pump device 40 received by the communication unit 22. When detected, the pump 13 may be started at a water level lower than the pump starting water level HWL.

  Accordingly, when the control unit 21 detects that the measured value of the rainfall per unit time measured by the rain gauge provided in the upstream manhole pump device 40 is equal to or more than a preset second threshold value, When it can be determined that more water flows in and it is detected that the upstream pump 43 is activated in such a case, the pump 13 is activated at a water level lower than the pump activation water level HWL. Occurrence of abnormally high water levels and overflow of water from manholes can be avoided in advance.

  In the above-described embodiment, the case where the pump 13 is started at a water level lower than the pump activation water level HWL when it is detected that the upstream pump 43 is activated has been described. However, the pump activation water level HWL is a predetermined activation. The pump activation water level HWL may be variably set so as to be lower than the water level.

  For example, the control unit 21 detects that the upstream pump 43 is activated, and sets the predicted water level VL based on the detected water level PL by the water level gauge 14 and the amount of water predicted to flow in from the upstream pump 43. When the calculated water level VL is equal to or higher than the pump starting water level HWL, the pump starting water level HWL is not limited to the case where the pump 13 is started at a water level lower than the pump starting water level HWL. The pump activation water level HWL may be variably set so as to be lower than a predetermined activation water level.

  In addition, the control unit 21 determines the upstream pump based on the rising speed v1 of the water level calculated based on the water level detected by the water level gauge 14 and the control information of the upstream manhole pump device 40 received by the communication unit 22. When it is detected that 43 is activated, the pump activation water level HWL is set lower than a predetermined activation water level, and the pump activation in which the water level in the manhole 12 detected by the water level gauge 14 is set lower than the predetermined activation water level. When the water level is reached, the pump 13 may be activated.

  In addition, the control unit 21 has an upstream manhole pump device in which the rising speed v1 of the water level calculated based on the water level detected by the water level gauge 14 is equal to or higher than a preset first threshold value and received by the communication unit 22. If it is detected that the upstream pump 43 is activated based on the control information 40, the pump activation water level HWL may be set lower than a predetermined activation water level.

  Further, the water level rising speed v1 calculated based on the water level detected by the water level gauge 14 is equal to or higher than a preset first threshold, and the control information of the upstream manhole pump device 40 received by the communication unit 22 is included in the control information. On the basis of this, when it is detected that the water level rising speed v2 of the upstream manhole pump device 40 is equal to or higher than a preset second threshold value, the pump activation water level HWL may be set low.

  In any case, when the amount of water inflow is predicted to increase, the pump start water level is set lower than the normal pump start water level HWL, so that the pump 13 starts early and an abnormally high water level HHWL is generated. This can reduce the risk of occurrence.

  In the embodiment described above, the case where there is one manhole pump device 40 adjacent to the manhole pump device 10 on the upstream side has been described, but the present invention can also be applied to the case where there are a plurality of adjacent manhole pump devices 40.

  In this case, the above-described control may be performed based on the control state obtained from any one of the manhole pump devices adjacent to the upstream side via the communication unit, and from a plurality of manhole pump devices. You may perform the above-mentioned control by the majority rule of the control state obtained via the communication part.

  Further, the above-described control can be executed based on control information from a manhole pump device installed not only upstream of the manhole pump device 40 adjacent to the upstream side but also upstream of the manhole pump device 40 adjacent to the upstream side. It is.

  In the above-described embodiment, the manhole pump apparatus is illustrated and described as a plurality of distributed processing facilities. However, the processing facility is not limited to this, and is applicable to various processing facilities in which monitoring targets are distributedly installed. can do.

  In the above-described embodiment, the configuration in which the water level is continuously detected has been described. However, the water level may be detected at a predetermined interval in consideration of the speed of the water level rise.

  The specific configuration of the control device and the operation method of the manhole pump device described above is not limited to the description of the embodiment, and it is needless to say that the design can be appropriately changed within the scope of the effects of the present invention. .
