Abstract

A method for automatically operating a filter bed and an apparatus thereof are provided to convert an automatic operation mode into a manual operation mode and to transmit an automatic operation release alarm and cause to a manager via voices or messages when a level meter is an abnormal condition or a valve or a pump of the filter bed and the filter bed do not perform a normal filtering or backwashing procedure. A method for automatically operating a filter bed comprises the following several steps. A management server receives and stores backwashing reference information of a water purifying plant, and constructs a backwashing reference information database(s101). The management server receives current state information of a level meter, a pump or a valve of the filter bed from a state sensor(s102), and checks whether the filter bed is in an automatic operation state(s103). If so, the server receives a current filtering maintenance time of the filter bed from a time sensor installed at the filter bed(s104), and checks whether the current filtering maintenance time is more than the backwashing time or the filtering time stored at the backwashing reference information database(s105). If not so, the server receives a current level value of the filter bed from a level sensor(s106) and checks whether the current level value is more than a backwashing initiation level stored at the backwashing reference information database(s107). If not so, the server receives the current time from the time sensor and checks whether the current time is between the backwashing start time and the backwashing termination time. If so, the server executes backwashing procedures of all the filter beds in a backwashing idle mode, and converts a mode of the filter bed, which terminates the backwashing procedure, into a filtering idle mode. The server estimates a mode conversion time of the filter bed, and broadcasts an important event in an automatic operation of the filter bed to an alarming unit, a terminal of a worker or a manager via voices or messages.

It is further configured to include the ability to match the total filter paper number. It is good.

Hereinafter, key terms used in the present specification will be described in detail.

The main parameters of the present invention include the total number of filter papers, filter duration, backwash start filter level, backwash start water level, backwash start time, which are registered in advance by a worker who is working in a filter paper of a water purification plant or a manager working in a control center. Overtime, back end time, and bird alarm setting time.

"Total number of filter papers" is a variable arbitrarily set by an operator such as a manager or worker in consideration of the design capacity and the flow rate of the filter paper. As an example, if the design capacity per filter paper is 500 tons and the water flow rate is 3000 tons, the total number of filter papers operating in the water purification plant will be set to "6 papers." In this case, if the management server switches one or more of the filter papers in the filtration mode to the backwash standby mode, the filter paper in the standby mode is switched to the filtration mode and operated in the filtration standby mode so that a total of six filter papers are always used for filtration. Keep running.

"Backwash start filtration time" is a time used as a reference for switching the filter paper in the filtration mode to the backwash standby mode. As an example, if the “backwash start filtration time” is set to 72 hours by an operator such as an administrator or worker, the management server selects the mode of the filter paper in which the “current filtration duration” has passed 72 hours among the filter papers in the filtration mode. After switching to the backwash standby mode at, one of the other filter papers in the filtration standby mode is switched to the filtration mode.

The "backwash start water level" is a variable used as a reference for switching from the filtration mode to the backwash standby mode as in the filtration duration. As an example, when the backwash start level is set to 2.5m by an operator such as a manager or worker, the management server converts the filter paper having a water level of 2.5m or more from the filtration mode to the backwash standby mode. One of the filter papers in the other filtration standby mode is switched to the filtration mode.

"Backwash start time and backwash end time" means the time at which the management server starts and ends the backwashing of all filter papers in the backwash standby mode. Of course, the water level should be above a certain value and the recovery tank level should be below a certain value.

"Algae alarm setting time" is the time which becomes a reference | standard which generate | occur | produces a bird alarm alarm to the manager or worker of a water purification plant. As an example, if the bird alarm setting time is set to 24 hours and the backwash start water level is set to 2.5 m, the management server will check the algae if any filter paper with a current filter duration of 24 hours or less among the filter papers in the filter mode with a water level value of 2.5 m or more. Alarm Generates an alarm.

In summary, the management server filters the total filter paper by setting the total number of filter papers to the filter mode at all times, and when the filter paper level in the filter mode is higher than the "backwashing level", the filter paper is backwashed in the filter mode. After switching to the standby mode, one of the filter papers in the filtration standby mode is selected and switched to the filtration mode. Likewise, if the current filter duration is greater than the "backwash start filtration time" among the filter papers in the filtration mode, switch the filter paper from the filtration mode to the backwash standby mode, and select one of the filter papers in the filtration standby mode to switch to the filtration mode. do. In addition, the management server determines whether the current time is between the "backwashing start time and the end time" of the backwashing process time, and backwashing all filter papers in the backwashing standby mode when the backwashing process time corresponds.

Lastly, “algae alarm” means that when algae are produced due to an increase in the concentration of nitrogen and phosphorus in the water in the filter paper, the filter paper will be blocked earlier than usual and the backwashing will need to be done differently than usual. When the signs of algae are recognized, it will be necessary to protect the series of devices installed in the filter paper by promptly notifying the bird alarms to the managers or workers, such as alarms, to follow up.

Thereafter, the management server 100 is a state of the level of the filter paper and the state of the pump and valve of the filter paper or the state of the filter or filter of the filter paper, backwash, filtration atmosphere, backwash atmosphere, etc. Receiving one or more current state information required among various states, such as each process operation state (s102), it is determined whether or not the automatic operation of the filter paper is possible (s103).

If the filter paper is not in a state capable of automatic operation (s103n), the management server 100 switches the current automatic operation mode to the manual operation mode and the alarm generator 310 or worker terminal installed in the control center or water purification plant. The operation terminal 300 including any one or more of the 320 or the administrator terminal 330 transmits information such as an automatic operation mode release alarm signal and release cause such as a voice form, a text form or an image form (s108). do.

At this time, an operator such as a worker or a manager working in a water purification plant or a control center recognizes the automatic operation mode release alarm signal, identifies the cause of the release of the automatic operation mode, and completes maintenance or follow-up (s109). When the automatic operation mode restart command is transmitted using the same or the like, the management server 100 receives this and switches back to the automatic operation mode (s110).

In addition, the step of determining whether the automatic operation of the filter paper is possible can be carried out divided into a more detailed process as shown in Figure 5, first, the management server 100 from the state sensor 210 filter paper Receiving the status information of the water gauge (s131) determines whether the water level is capable of normal operation (s132), and if the water level is a state capable of normal operation, the management server 100 is filter paper from the state sensor 210 Receiving (s133) the status information of valves and pumps that are variously provided to perform the inflow, outflow, discharge, discharge, catching, backwashing and backwashing processes (s134); It is determined whether the valve and the pump are in a remote state capable of remote control (s135).

When the valve and the pump are capable of normal operation (s134y) and the remote state (s135y), the management server 100 processes each of the reverse generation mode, the back washing mode, the filtration standby mode, and the filtration mode from the state sensor 210. Receives the state information to be executed (s136) and determines whether or not each process can be normally executed (s137), and if the level gauge is not capable of normal operation (s132n), or the valve and If the pump is in a state in which normal operation is not possible (s134n), or not in a remote state (s135n), or in any one or more of states in which all of the processes are not normally executed (s137n), the management server 100 Recognizes that the filter paper is not capable of automatic operation (s103n) and converts the current automatic operation mode into the manual operation mode, and then informs that the automatic operation of the filter paper has been switched to the manual operation mode. Mode off an alarm signal and to the alarm generator 310 and the worker terminal 320 and the administrator terminal 330 Alert Service (s108) to the operating terminal 300 in the form of voice or text, such as the information including the release cause.

On the other hand, when the determination result of the above-described step s103 is that the automatic operation of the filter paper (s103y), the management server 100 is the current filter continuous filter of the filter paper being filtered from the time sensor 220 installed in the filter paper of the water purification plant. Receiving the time (s104) it is determined whether or not the current filtration duration time is more than the backwash start filtration time stored in the backwash reference information database (d101) (s105).

If it is determined that the current filter duration is not more than the backwash time filtration time (s105n), the management server 100 further receives the current level value of the filter paper being filtered from the water level sensor 230 installed in the filter paper of the water purification plant. (s106) Further, it is determined whether the current water level is equal to or higher than the backwash start water level stored in the backwashing reference information database d101 (s107).

As a result of the judgment in step s105, the current filtration duration is more than the backwash time filtration time (s105y, or more), or the current water level is above the backwash start water level (s107y, or more), and the current filtration duration is less than the tide alarm set time. If it is not (s113n, exceeded), the management server 100 switches the corresponding filter paper from the filtering mode to the reverse generation mode (s111), and the filter paper of any one of the filter paper in the filter standby mode filter mode In operation S112, the number of filter papers in operation coincides with the total number of filter papers stored in the backwash reference information database d101.

In addition, if the current water level is greater than the backwash start water level (s107y, if the determination result of s107) and the current filter duration is less than the bird alarm setting time (s113y), the management server 100 alarms to inform the bird alarm It generates (s114) and broadcasts the alarm to the operating terminal 300 of the alarm generator 310 or manager terminal 330 and the worker terminal 320.

Thereafter, the management server 100 receives the current time from the time sensor 220 or the like (s121) to determine whether the current time is between the backwash start time and the backwash end time stored in the backwash reference information database d101. It is determined (s122). For example, if "backwash start time = 22:00" and "backwash end time = 06:00" and the current time is greater than 22:00, that is, the current time is between s122y) If the management server 100 executes the backwashing process for all filter papers in the backwash standby mode in the water purification plant (s123), and the filter paper after the backwash is finished to switch to the filtration standby mode (s124).

In addition, if the current time is not between the backwash start time and the backwash end time, the current state information will be received and executed again in steps s102 and s103 for determining whether automatic operation of the filter paper is possible.

In addition, the management server 100 predicts the mode switching time of the filter paper in advance (s125), and before and after the mode change mode change information, process progress information when performing the backwashing process, important events of the automatic operation of the filter paper, including bird alarms during bird detection In the form of voice or text, the alarm generator 310, the worker terminal 320, or the administrator terminal 330 may broadcast the alarm (s126) to any one or more.

7 is a reference diagram of an MMI screen showing the automatic driving state of the filter paper. In the case of Figure 7a as an example of the MMI screen according to an embodiment of the present invention, each of the filter paper operation state (for example, current mode, filtration duration, backwash start water level, etc.) composed of a plurality of managers or workers The operator can check at a glance. In addition, Figure 7b is an example of an MMI screen according to another embodiment shows a state in which the bird alarm in the form of a letter is output in the center.

So far, various embodiments of the present invention have been described in detail.
