DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring and control device in a water treatment and sewage purification treatment facility, and more particularly, to each treatment device constituting a purification treatment process in water and sewage treatment and their alternative treatment devices. The present invention relates to a monitoring and control device in a water and sewage purification treatment facility capable of remotely monitoring the operation of a plant and remotely controlling the operation.

[0002]

2. Description of the Related Art In a currently operated sewage treatment facility, an alternative processing apparatus for performing a processing operation in place of a failure when each processing apparatus performs a series of purification processing steps is installed in parallel. Each processing device and each of the alternative processing devices are provided with a failure detector for detecting their failure.

In such a conventional sewage treatment facility, when a failure detector detects a failure in one of the processing units, the operation is automatically performed to an alternative processing unit corresponding to the processing unit in which the failure is detected. It can be switched. In addition, these sewage treatment facilities are equipped with a failure notification light called a patrol light, and when a failure is detected in any of the processing devices, an alternative light corresponding to the detected processing device is detected. At the same time when the operation is switched to the processing device, the patrol light blinks or turns on.

In a conventional sewage treatment facility, a control device for controlling the operation of a series of processing devices constituting a purification process of the sewage treatment facility is provided, and an operation panel for operating the control device is also provided. It is installed only in the treatment facility. The operation data of a series of processing units, that is, the water level and the amount of processing in the processing tank of each processing unit, are transmitted to a distant data processing means via a telephone line or the like and recorded on a recorder. Has been done. The above is basically the same in the water treatment facilities for water supply.

[0005]

However, in such a conventional water and sewage purification treatment facility, when a failure occurs in any of the processing units, the failure is detected by a failure detector. If it operates normally, the operation is immediately switched to the corresponding alternative processing device, and a series of steps of the purification process is to be continuously operated without a break. It is only performed by a patrol light, which simply flashes or turns on, and cannot tell which processing unit has failed.

Therefore, the manager of the purification facility cannot know which of the processing units has failed, even if he knows that one of the processing units has failed. As a result, the manager of the purification treatment facility has to look around the entire system and inspect each treatment device in order to identify the faulty device, which is extremely inefficient.

In some cases, the alternative processing apparatus may not start the alternative operation for some reason. In such a case, the failure of one processing apparatus immediately impedes the operation of the entire facility. Therefore, it is necessary to promptly identify the faulty processing apparatus, start the manual operation of the alternative processing apparatus, and take other appropriate measures to avoid stopping the operation of the processing facility.

[0008] However, there is no device in the conventional water treatment and purification system for water supply and sewerage to notify whether or not the alternative treatment device has started to operate normally. It is necessary to check whether the operation is performed, and there is a problem that the efficiency is further deteriorated.

Furthermore, in a conventional water treatment and purification system for water and sewage, since the operation panel of the control device is installed only in the purification system, remote control cannot be performed, and the current operation of the purification system is not possible. Regarding the operation status, the water level and the processing amount of the processing tank of each processing device are transmitted to a distant data processing means via a telephone line or the like.
Because it merely keeps a record, at a distance, a further situation, that is, whether any of the series of processing equipment has failed, what the state of the failure is, and even more It is not possible to know whether or not the corresponding alternative processing device has started operation.

The present invention has been made in view of the above-described problems, and it is an object of the present invention to determine whether or not a failure has occurred in any of a series of treatment equipment in a water and sewage purification treatment facility and a corresponding alternative. With the operating means and the display means in the facility, whether or not the alternative operation of the processing device has started normally can be clearly known, and necessary operations can be performed,

The control unit 6 displays the operation state and the abnormal state as a processing step screen of the processing unit 2 or the alternative processing unit 5 as shown in FIG. 2, and in particular, the abnormal state is described later with reference to FIGS. As shown in (1), the detailed device configuration of the processing device in which the abnormality has occurred is sequentially displayed in a hierarchical manner.

Further, the control means 6 performs a process according to a command input and operated by touching the touch panel 9 or the touch panel 14. As an instruction from the touch panel 9 or the touch panel 14, for example,
A display command for causing the display unit 8 or the display 13 to output the forced operation instruction of the alternative processing unit 5 or the time series data of the operation state stored in the storage unit 7;
There is a record output command or the like to print out on a recording paper.

Next, the operation will be described. As shown in the flowchart of FIG. 3, the monitoring and control device 1 of the sewage purification treatment facility of this embodiment detects the detector 3 installed in the processing means 2 and the detector 4 installed in the alternative processing means 5. Based on the result, while controlling the purification processing of the processing means 2 and the alternative processing means 5, when the detector 3 or the detector 4 detects an abnormality of the processing means 2 or the alternative processing means 5,
Perform abnormality control processing.

That is, the monitoring and control device 1 comprises the processing means 2
The detector 3 always detects the operation state and the abnormal state of each processing device of the processing means 2, and the detector 3 outputs the detection result to the control means 6 as operation state data and an abnormality detection signal. Further, the monitoring and control device 1 uses the detector 4 installed in the alternative processing means 5 to execute the alternative processing means 5.
The detector 4 constantly detects the operation state and the abnormal state of each of the alternative processing devices, and outputs the detection result to the control means 6 as the operation state data and the abnormality detection signal.

The control means 6 checks whether or not an abnormality detection signal has been input (step S1). If the abnormality detection signal has not been input, the control means 6 controls the cleaning operation (step S2). Then, the control means 6 controls the operation of each processing device of the processing means 2 based on the operation state data input from the detector 3 and the detector 4, and based on the input operation state data, FIG. Display 8 shown
The operation state is displayed and output on the processing step screen (step S3).

The control means 6 controls the display 8
Display data to the remote control facility 17 via the modem 11
And causes the display 13 installed in the remote control facility 17 to display and output the same display data as the display 8 (step S3). This display 8
The display on the display 13 is performed by, for example, displaying the operation status of each processing device displayed on the processing step screen shown in FIG. Is displayed and output by a method of displaying a water level line. Needless to say, the display of the operation state is not limited to the above method.

Next, the control means 6 causes the storage means 7 to store the operation state data input from the detectors 3 and 4 as time series data of the operation state (step S4). It is checked whether there is a print output command (step S5).

In step S5, when a print output command is input, the control means 6 reads out the time-series data of the operating state from the storage means 7 and prints the time series data of the printing means 10 and the printing means 1.
5, and output the time-series data of the operating state on the recording paper by the printing means 10 and the printing means 15, and return to step S1 (step S6).
Note that, when a print output command is input, time-series data of the operating state may be output to the display 8 and the display 13 so that the display 8 and the display 13 also display and output the time-series data. If no print output command is input in step S5, the process returns to step S1 to check whether an abnormality detection signal has been input.

In step S 1, when an abnormality detection signal is input from the detector 3, the control unit 6 determines whether an abnormality has occurred in each processing unit of the processing unit 2 based on the input abnormality detection signal. Which of these devices has occurred, and at which location of which device it has been identified (step S7), and an abnormality of the processing means 2 of the processing devices of the alternative processing device 5 has occurred. An operation start signal is output to the processing device corresponding to the processing device that is present, and the operation of the processing device of the alternative processing device 5 is started (step S8).

When the control means 6 outputs an operation start signal to the alternative processing device 5, the control means 6 outputs abnormality display data to the display 8 and the display 13 of the remote control facility 17, and notifies the display 8 and the display 13 of the abnormality occurrence. Is performed (step S9).

The notification of the occurrence of an abnormality is first made by blinking the abnormality occurrence device among the processing devices displayed on the processing process screen shown in FIG. 2 in red and sounding a buzzer or the like. As described above, this abnormality occurrence notification is made by the display 8 or the buzzer of the purification facility 16 and the display 1 of the remote control facility 17.
3 and a buzzer, so that the occurrence of an abnormality can be confirmed in both the purification treatment facility 16 and the remote control facility 17. Note that the notification of the occurrence of an abnormality is not limited to the above method.

Next, the control means 6 checks based on the detection signal of the detector 4 whether or not the processing facility which has output the operation start signal among the alternative processing devices of the alternative processing means 5 has started its operation normally ( In step S10), when the operation is not started normally, the fact that the substitute process has not been started is displayed on the display 8 and the display 13 (step S11).

In response to the display indicating that the alternative processing has not been started, it is checked whether or not the forced operation of the alternative processing device 5 has been performed by the touch panel 9 or the touch panel 14 (step S12). Then, the process returns to step S9 to repeat the same process from the abnormality occurrence display process.

When the forced operation is performed in step S12, the control unit 6 operates the processing unit corresponding to the processing unit of the processing unit 2 in which the abnormality has occurred among the alternative processing units of the alternative processing unit 5. By outputting a start signal, the alternative processing device of the alternative processing means 5 starts an alternative process (step S13), and returns to step S9 to display an abnormality occurrence display.

As described above, when an abnormality has occurred in the processing means 2 and the alternative processing means 5 has not started operating normally, a message to that effect is displayed. , The operation of the alternative processing means 5 can be started, and the sewage purification processing can be immediately continued without delay.

In step S10, when the alternative processing means 5 starts operating normally, it is checked whether or not a hierarchy display command operation has been performed from the touch panel 9 or the touch panel 14 (step S14). As shown in FIG. 4, the detailed device configuration of the processing device in which the abnormality has occurred, that is, the device configuration of the lower layer of the processing device is displayed on the display 8 and the display 14 (step S15), and the process returns to step S14.

For example, if an abnormality occurs in the system of the pump P1 of the raw water tank 21 shown in FIG.
Indicates that the pump P shown in FIG.
When the touch panel 8 or the touch panel 14 at the position corresponding to the display position of the pump P1 that is flashing red is touched in step S14, as shown in FIG. The device configuration, for example, the control panel 30 and the like are displayed, and the device component in which the abnormality has occurred, for example, the control panel 30, is displayed in red blinking.

Further, if there is a hierarchy display instruction in step S14, a lower-level device configuration showing a more detailed device configuration is displayed on the display 8 and the display 13 (step S14), and the process returns to step S14. In this more detailed display of the lower-level device configuration, for example, in the above example, when the control panel 30 shown in FIG. As shown in FIG.
51 is displayed, and when an abnormality occurs in the device configuration, for example, when an abnormality occurs in the relay 42, the relay 42 flashes red.

As described above, when an abnormality occurs in the processing apparatus, the occurrence of the abnormality can be promptly confirmed by the abnormality occurrence report, and the location of the abnormality occurrence is indicated on the display 8.
And the display 13 sequentially displays the hierarchy, so that the device configuration of the processing unit 2 in which the error has occurred and the device configuration in which the error has occurred do not have to go to the site one by one, as in the related art, but quickly. In addition, it is possible to accurately confirm, and it is possible to quickly perform the repair work.

Further, the above-mentioned abnormality occurrence notification and abnormality occurrence display are also performed on the display 13 of the remote control facility 17, and the hierarchical display is performed by the hierarchical display instruction from the touch panel 14 of the remote control facility 17. So
There is no manager at the purification facility 16 and the remote control facility 17
Even when there is an administrator only in the purification treatment facility 16
It is possible to promptly and accurately confirm the occurrence of the abnormality and the location of the occurrence of the abnormality without going out to the facility.

In step S14, if there is no hierarchy display instruction and there is a print output instruction (step S16), the control means 6 causes the recording means 10 and recording means 15 to record and output the abnormality occurrence status on recording paper (step S16). S17) If there is no print output instruction in step S16, the abnormality occurrence status is stored in the storage means 7 (step S16).
5) Returning to step S1, the same processing is performed.

As described above, according to the monitoring and control device 1 in the sewage purification treatment facility of this embodiment, the processing means 2 for performing a series of purification treatment steps for water and sewage and the processing means 2 The detector 3 and the detector 4 detect the processing operation of the alternative processing unit 5 that performs the alternative processing, and when an abnormality of these processing operations is detected, outputs an abnormality detection signal to the control unit 6.

When the abnormality detection signal is input, the control means 6 outputs an operation start signal to the alternative processing means 5 and performs alternative processing on the alternative processing apparatus corresponding to the processing apparatus in which the abnormality has occurred. At the same time, the data of the abnormal state of the processing means 2 and the data of the alternative processing state of the alternative processing means 5 are displayed on the display 8 and the modems 11 and 12 as communication means.
Then, the information is output to the remote control facility 17 via the dedicated line 18, and the fact that the abnormality has occurred in the processing means 2, the abnormality state thereof, and the operation state of the alternative processing means 5 are displayed on the display 8 and the display 13.

Therefore, not only in the purification treatment facility 16 but also in the remote control facility 17 located in a remote place, it is possible to quickly and accurately know that an abnormality has occurred in the processing means 2 and the abnormal situation. Alternative processing means 5
Can be known, and it is possible to appropriately and promptly respond to the occurrence of an abnormality.

In this embodiment, the control means 6
During the abnormality control processing, abnormal state data is output to the display 8 and the display 13 as hierarchical data of devices in each of the alternative processing units of the processing unit 2 or the alternative processing unit 5 in which the abnormality has occurred, Touch panel 9
