DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm notification device, and particularly when a power failure occurs at a plurality of water supply and sewage pump facilities at a plurality of locations, when a pump manager operates these pumps using a private power generator. The present invention relates to an alarm notification device that can estimate which of a plurality of pumps needs to start operation.

[0002]

2. Description of the Related Art Pumps used for draining water from a full tank are installed in facilities such as water supply and sewerage. Due to the importance of the facilities, this water and sewage pump requires auxiliary equipment of a private power generator so that it can be operated even when the commercial power supply is cut off.However, depending on the installation conditions of the pump facility, a permanent power generator cannot be installed permanently. There is. In this case, in the event of a power outage, the administrator of the pump is driving the mobile in-house power generator by car or the like.

When there are a plurality of pump facilities, it is necessary to determine which pump should be operated by the private power generator. The timing and order of the operation start of the pumps are not determined in advance, but are determined by the inflows to the respective pumps when a power failure occurs. for that reason,
Data such as inflow and water level are required, but it was not possible to monitor the inflow and water level due to a power outage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the alarm notification device according to the present invention will be described below with reference to FIGS. FIG.
BRIEF DESCRIPTION OF THE DRAWINGS It is explanatory drawing of the alarm notification system of the manhole pump installation which installs the alarm notification device of an Example. FIG. 2 is an explanatory diagram of the calculation PAD of the average value of the operation intervals of the manhole pump in the alarm notification device of the embodiment. FIG. 3 is an explanatory diagram of an example of an alarm notification at the time of a power failure in the alarm notification device of the embodiment.

An embodiment will be described. The alarm notification device 1 of the present embodiment includes a circuit that detects an operation signal of a pump, a circuit that detects a power failure, a CPU, and a communication component, and has a function of reporting an alarm when a power failure is detected. And a function of notifying the time when the operation of the pump should be started together with the alarm. Further, it has a function of reporting the elapsed time from the pump operation start time. And it has a function of reporting the average value of the pump operation intervals calculated by the CPU. In addition, since the alarm notification device operates at the time of a power failure, the alarm notification device has a function of enabling notification during a power failure using power of a battery outside or inside the device.

As shown in FIG. 1, the alarm notification device 1 of the embodiment is installed in a manhole pump facility 2. The manhole pump equipment 2 includes a manhole 3, an inflow pipe 4 for flowing sewage into the manhole 3, a water pipe 5 for discharging sewage in the manhole 3, a water level gauge 6 for measuring the water level of the manhole 3, and a sewage in the manhole 3. Detachable submerged sewage pump 7 for allowing water to flow out of water pipe 5, power line 8 from a system power supply for supplying power to detachable submerged sewage pump 7,
The control panel 9 of the detachable underwater sewage pump 7, the telephone line 10 for reporting an alarm from the alarm reporting device 1, the power line 8 from the system power supply, and the drop-in switchboard 1 for retracting the telephone line 10.
1 and the like, and the same manhole pump equipment 2b,
Along with 2c, it is connected to a telephone line 41. The telephone 42 is connected to the telephone line 41 and can receive a voice report from the manhole pump facilities 2 to 2c. The monitoring device 43 is connected to the telephone line 41 via the modem 44.
And similarly, manhole pump equipment 2
2c can be received. In addition,
An alarm notification is provided by an operation signal 31 for transmitting the operation of the detachable underwater pollution pump 7 to the alarm notification device 1 and a power failure detection signal 32 for transmitting a power failure to the power line 8 from the system power supply to the alarm notification device 1. The device 1 can know the operation status of the pump 7 such as the operation start time and the operation stop time, and can detect a power failure.

A description will be given of an example of a process of calculating an operating condition at the time of energization in the alarm notification device 1 according to the embodiment. In the manhole pump facility 2, when a certain amount of sewage entering from the inflow pipe 4 is stored in the manhole 3, the detachable submersible sewage pump 7 starts operating in response to a signal from the water level gauge 6. When the alarm notification device 1 receives the operation signal 31, the average value of the operation intervals is calculated from the last five operation start times in accordance with the PAD diagram shown in FIG. In addition, manhole pump equipment 2
When the amount of sewage in the manhole 3 becomes equal to or less than a certain amount, the detachable underwater sewage pump 7 stops in response to a signal from the water level gauge 5. Then, when the driving signal 31 disappears, the alarm notification device 1 calculates the average value of the driving time from the past five driving times according to the PAD diagram shown in FIG. FIG. 2B shows a calculation formula of each average value.

Next, the operation at the time of a power failure in the alarm notification device 1 of the embodiment will be described. Since the detachable underwater sewage pump 7 does not operate during a power outage, the sewage flowing from the inflow pipe 4 overflows the manhole 3 if the pump is kept as it is. Therefore, the manager brings the mobile private power generator to the manhole pump facility 2. In the conventional method, since it is not known when the sewage overflows from the manhole, it is necessary to immediately go to the manhole pump facility upon receiving an alarm report at the time of a power outage and wait on the spot. On the other hand, in the present embodiment, when an alarm notification from the alarm notification device 1 is received, the time at which the detachable submersible sewage pump 7 should be started, the elapsed time from the immediately preceding operation start time, the average value of the operation interval, the operation You can get the average value of time, etc.
It is possible to estimate the time at which the detachable submersible sewage pump 7 is to be operated, and by that time, the mobile private power generator can be brought to the manhole pump facility 2 and the detachable submersible sewage pump 7 can be operated. .

Also, actually, the manhole pump equipment 2
As shown in FIG.
For this reason, when a power failure occurs, it has not been known from which of these manhole pump facilities the pump should be operated. On the other hand, in the present embodiment, since all of the manhole pump facilities 2 to 2c receive a report as shown in FIG. 3 as an example, it is possible to determine from which manhole pump facility to start operation using these reports. .
