Drainage facilities are being used. Any manhole pump 5
When the zero pump P itself fails or an air lock or suction blockage occurs, the sewage in the manhole 51 cannot be drained, and the sewage may overflow from the manhole 51. Therefore, each manhole pump 50 (50-
1-7) is installed in the control panel 55 (55-1-7) installed in the manhole pump 50 to notify the outside that an abnormality has occurred in the manhole pump 50. If an abnormality is detected that there is a risk of overflowing, the contents of the abnormality are detected by voice, fax, pager, modem signal, etc., or by radio or telephone via a public telephone line or leased line telephone line. The central monitoring and control device of the management center that controls the entire system, while the central monitoring control device and the telephone that received the notification notify the notification device of the manhole pump 50 upstream of the manhole pump 50 in which the failure has occurred. The control signal is automatically or manually transmitted to the door and the interlock is applied to stop the operation of the pump P to stop the water supply to the manhole pump 50 where the failure has occurred. Unishi which was. However, in the above-described conventional method, if the central supervisory control device is in use or breaks down, there is a risk that a time delay may occur in response to the operation stop of the upstream manhole pump 50, etc. In the case of the control by, there is a drawback that the control cannot be performed when the operator is absent. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and its object is to easily, quickly and reliably cope with the stoppage of the upstream manhole pump when an abnormality occurs. It is an object of the present invention to provide a reporting device having a mutual interlock control function between reporting devices. In order to solve the above-mentioned problems, a reporting device having an interlock control function between reporting devices according to the present invention is connected to a plurality of manhole pumps from upstream to downstream. In the reporting device attached to each manhole pump of the drainage facility that pumps up the water accumulated in the manhole pump and then flows to the manhole pump on the downstream side, the reporting device attaches this reporting device When it is detected that the manhole pump has trouble collecting water from the upstream, an interlock control signal is directly transmitted to the notification device of the upstream manhole pump connected to the manhole pump via the communication means. It is configured to stop the water supply of the upstream manhole pump by sending Features. DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a line connection configuration example of a notification device according to an embodiment of the present invention. This line connection configuration example is described so as to correspond to the configuration of the drainage facility shown in FIG. As shown in the figure, the control panel 55 (55-1 to 7) of each manhole pump 50 (50-1 to 7) (see FIG. 2) is a power circuit 57 (57-1 to 57-1) for driving the pump P and the like. 7), a control circuit 59 (59-1 to 7) for controlling the power circuit 57, and a notification device 60 (60-) for transmitting and receiving data to and from an external communication line.
1 to 7). Each notification device 60 can transmit a control signal to the notification device 60 of the manhole pump 50 directly upstream of the manhole pump 50 to which the notification device 60 is attached via a public line or a dedicated line. It is connected. That is, for example, the notification device 60-1 is shown in FIG.
The three manhole pumps 50-2, 3, 4 are directly connected to the upstream side of the manhole pump 50-1 shown in FIG.
So at least these manhole pumps 50-
It is configured so that a control signal can be directly transmitted to the notification devices 60-2, 3, 4 of 2, 3, 4 and the notification device 60-2.
Are directly connected to the upstream side of the manhole pump 50-2 because the three manhole pumps 50-5, 6, 7 are at least these manhole pumps 50-5,
A control signal can be directly transmitted to 6, 7 reporting devices 60-5, 6, 7. Each notification device 60 receives various types of failure information from the control circuit 59, and the information is stored in the notification device 6.
0 to a central monitoring control device of a management center (not shown) that controls the entire drainage system via a public line or a dedicated line, while each central monitoring control device also sends a Information required for controlling the manhole pump 50 is input to the reporting device 60. Of the various types of failure information input from the control circuit 59 to the notification device 60, when failure information indicating that there is a problem in collecting water flowing from the upstream into the manhole pump 50 is notified. The device 60 transmits the information to the central monitoring control device (or without transmitting it to the central monitoring control device), and at the same time, the notification device of the manhole pump 50 directly connected to the upstream side of the manhole pump 50 in which the notification device 60 is installed. 60 (which reporting device 6
Whether to report to 0 is set in each reporting device 60 in advance)

The operation of the manhole pump 50 is stopped. On the other hand, the manhole pump 50 on the side transmitting the interlock signal
When the abnormality is canceled, the notification device 60 transmits an interlock release signal to the interlock signal transmission destination notification device 60 to release the interlock, and returns to normal operation. This will be described more specifically. If there is a problem in collecting water flowing from the upstream in the manhole pump 50-1, for example, drainage from the manhole 51-1 becomes impossible, or the amount of drainage becomes extremely small (for example, the pump P itself has failed). If the pump P has an air lock or suction blockage, or the pump P cannot be operated due to a power failure), the manhole 51-
If the sensor detects that the water level in 1 has risen to an abnormally elevated water level, that is, if there is a risk of sewage overflowing from the manhole 51-1, the manhole pump 50-1 may be repaired, It is necessary to prevent the inflow of sewage from the upstream until the power failure is restored. Therefore, the notification device 60-1 is an interlock signal to the notification devices 60-2, 3 and 4 of the manhole pumps 50-2, 3 and 4 connected directly upstream of the manhole pump 50-1. Is transmitted to stop the operation of the manhole pumps 50-2, 3, and 4. The reporting devices 60-2, 3, and 4 that are reporting destinations are set in advance in the reporting device 60-1. When making a report via a public line, for example, as shown in FIG. 3 (a), an "interlock report destination telephone number" (the telephone number of each reporting device 60-2, 3, 4),
“Dedicated line report identification character” (indicating that the report content is an interlock signal) and “Dedicated line report identification code” (number of the telephone, for example, 1 for the master unit, 2, 3 for the slave unit,・ ・) And “Interlock report destination ID number” (ID number that enables access to the report device) to notify the report device in the dedicated line, for example, as shown in FIG. "Leased line report identification character"
And “dedicated line report identification code” and “interlock report destination ID number” are used. Notification device 6 which has received the interlock signal

The control circuits 59-2, 3 and 4 that received the interlock signal cut off the output circuit that controls the power circuits 57-2, 3 and 4 in response to the signal, As a result, the manhole pump 50-2,
The operation of 3 and 4 is stopped, the water supply to the manhole pump 50-1 in which a failure has occurred is stopped, and the overflow of water from the manhole pump 50-1 is prevented. On the other hand, when the manhole pumps 50-2, 3, 4 are stopped, for example, the manhole pump 5
If the water level in the manhole 51-2 reaches an abnormally rising water level due to the sewage flowing in from 0-2 on the upstream side, the sewage may overflow from the manhole 51-2. Manhole pump 50-
An interlock signal is transmitted to each of the notification devices 60-5, 6, 7 of 5, 6, and 7 to send manhole pumps 50-5,
Stop operations 6 and 7. When the abnormality of the manhole pump 50-1 is recovered by repair by a repair worker or cancellation of a power failure and returned to the normal water level, the reporting device 60-1 reports the reporting destination that transmitted the interlock signal. Device 60-2,
An interlock release signal is transmitted to 3 and 4. Control circuit 59-2 having received the interlock release signal;
3 and 4 are power circuits 57-2, 3 and 4 corresponding to the signals.
Release the shutoff of the output circuit that controls, and resume its operation. When the sewage water level in the manhole 51-2 returns to the normal water level due to the resumption of the operation of the manhole pump 50-2, the reporting device 60-2 similarly reports to the reporting device 60-5.
The interlock release signal is transmitted to 6, 7 and the operation of the manhole pumps 50-5, 6, 7 is resumed. Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims and the technical idea described in the specification and drawings. Can be modified. It should be noted that any configuration not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, the condition for the reporting device to transmit the interlock signal is not limited to the above condition, and may be any condition as long as it is a problem that the manhole pump has a problem in storing water from the upstream. Further, the communication means for connecting the reporting devices may be other various communication means such as various network lines. As described in detail above, according to the present invention, since the interlock control and release are performed directly between the reporting devices, even if the central supervisory control device is in use or fails. However, even if there is no operator in the case of control by telephone, there will be no time delay in response to the operation stop of the upstream manhole pump, etc.
This can be done easily, quickly and reliably. Even if there is no central monitoring and control system or telephone control system, the emergency of dispatching to the pumping station located upstream of the faulty pumping station and stopping the operation is eased every time a fault occurs. Now you can have enough time to go out.
