Description

Method and device for processing shift-switching information of sewage treatment plant

Technical Field

The present invention relates generally to the field of sewage treatment technology, and more particularly, to a shift information processing method and apparatus for a sewage treatment plant.

Background

Sewage treatment is a physical, chemical and biological reaction process which runs continuously throughout the year. The large and medium sewage treatment plants have complex process flow and numerous equipment, and pollutants can be removed and converted through a plurality of treatment units.

In order to ensure the normal operation of the sewage treatment process and the production and living requirements of staff in the factory, auxiliary systems and facilities such as a warehouse, a fire protection system, a heating, ventilation and air conditioning system and the like are also arranged in the factory. Sewage treatment plants typically require 24 hours a day to be attended to monitor whether the sewage treatment process is proceeding properly, for example, to monitor whether agents (e.g., glucose, sodium hypochlorite, etc.) required for sewage treatment are added on time, to see if production and auxiliary systems and facilities are in good condition and to timely report and dispose of problems encountered, etc. Therefore, the operation and maintenance personnel generally adopt a shift working mode of two shifts or three shifts to meet the actual requirements of the sewage treatment plant.

Under the working mode of shift making, the on-duty operation and maintenance personnel are shifted to new operation and maintenance personnel at a certain appointed time point, then leave the factory for rest, and after the new operation and maintenance personnel are shifted to work, the operation and maintenance personnel enter the on-duty state and take on the responsibility of operation and maintenance. In order to make responsibility clear and check the responsibility, the office workers usually fill out office records to record the sewage treatment operation condition, the key equipment operation and repair condition, the tool checking condition, the on-duty carry-over problem and the like.

At present, most of the shift-over record forms of sewage treatment plants adopt paper documents, and are manually filled out by operation and maintenance staff during each shift-over, and are regularly arranged and recorded. However, paper shift register is easy to change, damage or lose, and the problems of inconvenient searching and analysis and the like exist.

With the development of computer and information technology, the shift-to-shift management system has been developed, and the application fields thereof include hospitals, car parks, railway stations and the like. For example, for a hospital application scenario, a healthcare worker shift system may be designed that supports information input modes of images, voice, and keyboards. For a shift-exchange system designed for a parking lot manager, the system identifies shift-exchange personnel by collecting fingerprints or facial images to support multi-person shifts. In addition, the shift-exchange system can be designed based on technologies such as fingerprint, voice and face recognition.

Although the above-described shift management system has made substantial progress over conventional paper shift register tables. However, the shift-over management system is more focused on identity identification and confirmation of shift-over staff, and cannot effectively monitor production conditions and equipment operation states in the shift-over process, so that management requirements of a sewage treatment plant on the shift-over process are difficult to meet.

Detailed Description

Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

Fig. 1 illustrates a flowchart of a shift information processing method of a sewage treatment plant according to an exemplary embodiment of the present invention.

Referring to fig. 1, in step S10, a shift time difference between a shift time and a shift time is determined.

For example, the difference between the shift time and the shift time may be determined as the shift time difference. Here, the shift timing is the timing at which shift is performed the last time before the shift reception timing.

In step S20, a set of thresholds corresponding to the shift time difference is determined.

In a preferred embodiment, the shift information processing method of a sewage treatment plant according to an exemplary embodiment of the present invention may further include: the corresponding relation between the preset shift time differences and the preset threshold value sets is preset.

In this case, the step of determining the threshold set corresponding to the shift time difference may include: searching a preset shift time difference larger than the determined shift time difference from a plurality of preset shift time differences, determining the minimum preset shift time difference in the searched preset shift time differences, and determining a preset threshold value set corresponding to the minimum preset shift time difference as a threshold value set corresponding to the shift time difference.

The process of determining the threshold set corresponding to the shift time difference is described by way of the following example.

In this example, assuming that k preset threshold sets are preset, k preset shift time differences corresponding to the k preset threshold sets are t ₁ ,t ₂ ,...,t _k Wherein t is ₁ ＜t ₂ ＜...＜t _k 。

Calculating the shift-over time difference between shift-over time and shift-over time as t _h Searching for a shift time difference t greater than the shift time difference t from k preset shift time differences _h Assuming that 3 preset shift time differences (for example, 20 minutes, 25 minutes, 30 minutes) are searched in total, finding the minimum preset shift time difference (for example, 20 minutes) from the searched 3 preset shift time differences, and determining a preset threshold set corresponding to the minimum preset shift time difference as a threshold set corresponding to the shift time difference.

In step S30, a shift information table at shift time and a shift information table at shift time are acquired. Here, the shift-shift information table and the shift-reception information table each include determination format information including variable information acquired based on a preset processing item.

As an example, the shift information table and the shift information table may be stored in an SQL (Structured Query Language ) database, and query conditions for different data may be set based on the SQL database to define or narrow the query scope. Compared with the traditional electronic shift-switching record in a text format, the storage mode has the characteristics of convenience in data storage and use and flexibility in inquiry mode, and can better realize statistics and analysis of shift-switching information.

Fig. 2 shows a schematic diagram of a shift sequence of two shifts according to an exemplary embodiment of the present invention.

Fig. 2 shows the execution sequence of the shift-on of the operation and maintenance personnel using the two shift-on mode of operation. Here, only after the operation and maintenance person of the previous team submits the shift information table, the operation and maintenance person of the current team can submit the shift information table. As an example, if when the operation and maintenance person of the current team submits the reception information table, the operation and maintenance person of the previous team does not submit the overtime information table, a prompt message is generated to prompt the operation and maintenance person of the current team that the previous team has not completed the shift.

That is, the shift information processing method of the sewage treatment plant according to the exemplary embodiment of the present invention compares and analyzes a shift information table generated at shift time of a current shift group with a shift information table generated at shift time of a previous shift group to determine whether there is an abnormality in shift-over process, i.e., analyze shift-over conditions of different shift groups.

In the embodiment of the invention, the operation interface matched with the use authority corresponding to the different identities can be provided for the staff with different identities. As an example, three operation interfaces of a shift selector interface, a shift selector interface and a manager interface can be provided for the shift information processing requirement of the sewage treatment plant.

For example, the shift man interface can be filled by the operation and maintenance personnel on shift of the sewage treatment plant at shift time to generate a shift information table, and the shift information table is mainly used for recording the operation conditions of sewage treatment, sludge treatment and other technological processes, the operation and repair conditions of key equipment, the counting condition of tool articles, shift carry-over problems and the like at shift time.

The work reception interface can be filled by current operation and maintenance personnel of the sewage treatment plant at the work reception time to generate a work reception information table, and the work reception information table is mainly used for checking and recording the state and change of information recorded by the work reception personnel at the work reception time.

The manager interface can be used by a manager (such as a factory owner, an operation manager or other responsible personnel) of the sewage treatment plant, and main functions include personnel management, form management, threshold management, shift information viewing and statistical analysis and the like.

For example, personnel management may refer to adding, modifying, or deleting information of operators of a sewage treatment plant so that authorized shift operators can log into a shift operator interface and a shift operator interface. Form management may refer to deleting wrong or redundant shift information tables and shift information tables, so that the shift information tables and the shift information tables can be in one-to-one correspondence. Threshold management may refer to setting a set of thresholds. The checking and statistical analysis of the shift information can refer to displaying warning information in the shift process, displaying non-definite format information in a shift information table and a shift information table, and backtracking shift history information and statistical analysis of important parameters.

As an example, the three operation interfaces in the exemplary embodiment of the present invention may adopt login modes such as user name and password input, work card swiping, fingerprint identification or face recognition. For example, a shift information management system for implementing a shift information processing function of an exemplary embodiment of the present invention may be installed on a client, and when a login mode of swiping a work card is adopted, a card reader may be provided at the client and connected to the client. When the login mode of fingerprint identification or face recognition is adopted, a fingerprint reader or a camera can be arranged beside the client so as to send the identification and matching result of the fingerprint or face image to the client.

In a preferred embodiment, the client installed with the shift information management system may be located in a central room of a sewage treatment plant, as a software running independently, or as a functional module of the intelligent water service system. In order to reduce the cost of the shift information management system, a login mode of a user name and a password is preferably selected.

The following describes a shift man interface and a shift receiver interface, and a process of generating a shift information table and a shift information table based on the shift man interface and the shift receiver interface, respectively, with reference to fig. 3 and 4.

Here, it should be understood that, due to different process flows and auxiliary facilities of different sewage treatment plants, the monitoring data and equipment states of each sewage treatment plant will also have different emphasis, and the operation and maintenance management manners will also have certain differences, which will result in different information about the shifts required by different sewage treatment plants. Accordingly, the contents on the shift man interface and the reception man interface shown below in fig. 3 and 4 in connection with the demands of a certain sewage treatment plant are only examples, and the present invention is not limited thereto, and those skilled in the art may add or subtract the shown contents according to actual demands.

Fig. 3 illustrates a schematic diagram of generating a shift information table according to an exemplary embodiment of the present invention.

Fig. 3 shows a shift man interface for providing to a shift operator, where after the shift man interface is filled by the operator, after receiving a selection operation of a "submit save" button, a shift information table may be generated and uploaded to the SQL database.

The shift information table has the following characteristics:

(1) One shift information table corresponds to one shift information table only.

The shift information table corresponding to the current shift information table is the shift information table submitted last time after the current shift time. When a shift information table is submitted, the operation and maintenance personnel cannot submit a new shift information table again unless the operation and maintenance personnel submit a new shift information table, or the management personnel delete the submitted last shift information table at the management personnel interface.

(2) The login person name is free from input, the same group person name is free from input or the login person is manually added.

If the operation and maintenance personnel enter the shift-exchange personnel interface through the user name and the password, the name of the login person on the shift-exchange information table is automatically associated with the user name used during login. If the operation and maintenance personnel adopts a login mode of swiping a work card, fingerprint identification or face recognition, the name of the login personnel is automatically associated with the identified user name. If the same group of people can enter information through the modes of swiping a work card, fingerprint identification or face recognition, and the like, the same group of people in the shift information table can be automatically generated, otherwise, the names of the same group of people are manually input by a login person. When the content of the same group of people is empty, only the login people are on duty.

(3) The start time of the shift is automatically associated.

Preferably, the start time of the shift may be accurate to minutes. If the shift information management system is used for the first time, the start time of the shift can be manually input by a user, and after the first time of use, the start time of the shift is associated with the end time of the last shift in the last shift information table before the current moment and is automatically displayed in the shift information table. If the shift receiving information table closest to the current shift receiving information table is deleted on the manager interface, the shift starting time on the shift receiving information table is automatically related to the stop time of the shift in the latest shift receiving information table before the last shift.

(4) The end time of this shift is manually added.

The end time of this shift is also accurate to minutes, but is manually added by the operation and maintenance personnel who need to log in. Here, the end time refers to the time when the operator completes the shift (i.e., shift time), and preferably, each value of the operation data in the shift information table is a value at the end time.

(5) The value of the power consumption of ton water is automatically obtained, and other operation data are manually added or automatically obtained.

The ton water power consumption is calculated by dividing the power consumption by the water yield, and the manual change of operation and maintenance personnel is not allowed. In addition, other operation data such as the water inflow amount and the water outflow amount need to be manually added by operation and maintenance personnel, but the invention is not limited thereto, and the numerical values of the other operation data can also be automatically obtained from the corresponding monitoring devices.

(6) Fault maintenance information is divided into two categories.

For the resolved faults, the operation and maintenance personnel need to select the fault type and the fault level from preset options and manually input the fault description and the disposal condition. Preferably, only one resolved fault is filled at a time, and when there are multiple resolved faults, the multiple resolved faults can be added by clicking the increase button (e.g., the "+" button) on the left side.

For unresolved faults, the fault description and temporary measures need to be manually input by operation and maintenance personnel.

(7) The damage and the loss of the articles and other problems need to be filled manually by operation and maintenance personnel.

In a preferred embodiment, the shift information and the operation data cannot be empty, otherwise, when the shift information table is submitted, a prompt window is popped up in the shift personnel interface to prompt the operation and maintenance personnel to supplement the unfilled information item completely.

In the example shown in fig. 3, the preset processing items may refer to processing items in a numerical form (e.g., numerical items automatically calculated in the operation data or manually added by the operation and maintenance personnel) and processing items in a non-numerical form (e.g., fault type options and fault level options) that are set in advance.

That is, the user can only fill in the preset processing item according to the designated format, and the determined format information is variable information acquired based on the preset processing item in the numerical form and the processing item in the non-numerical form.

In a preferred embodiment, the shift information processing method of a sewage treatment plant according to an exemplary embodiment of the present invention may further include: the user is provided with a graphical interface (i.e., a shift man interface) for generating a shift information table, which may include a plurality of preset processing items therein.

For the case where the preset processing item includes a processing item in a numerical form, the numerical form variable may be acquired according to the user's input for the processing item in the numerical form.

For the case where the preset processing item includes a plurality of predetermined fault type options, one predetermined fault type from the displayed plurality of predetermined fault types may be selected according to a selection operation for selecting one predetermined fault type from the plurality of predetermined fault types entered by a user on the graphical interface.

For the case where the preset processing item includes a plurality of predetermined failure level options, one predetermined failure level from among the displayed plurality of predetermined failure levels may be selected according to a selection operation for selecting one predetermined failure level from among the plurality of predetermined failure levels inputted by a user on the graphic interface.

Preferably, the shift information table and the reception information table may further include non-deterministic format information in addition to the deterministic format information, and the non-deterministic format information may include text contents as an example.

In the example shown in fig. 3, the text content may include at least one of the following: fault description and handling of solved faults, fault description and temporary solving measures of unresolved faults, object counting information and remark information.

In this case, a fault description and disposition corresponding to the selected predetermined fault type and to the selected predetermined fault level may be received as input by a user on the graphical interface. In addition, the method can also receive the object counting information and/or remark information input by the user on the graphical interface.

Fig. 4 shows a schematic diagram of generating a reception information table according to an exemplary embodiment of the present invention.

Fig. 4 shows a job-receiving interface for an operation and maintenance person who provides a sewage treatment plant with a job, and after the operation and maintenance person completes filling the content in the job-receiving interface, a job-receiving information table can be generated and uploaded to an SQL database after receiving a selection operation of a "save" button.

The reception information table has the following characteristics:

(1) One shift information table corresponds to one shift information table.

The shift information table corresponding to the current shift information table is the shift information table submitted last time before the current shift time. When a shift information table is submitted, the operation and maintenance personnel cannot submit a new shift information table again unless the operation and maintenance personnel submit a new shift information table, or the management personnel delete the submitted last shift information table at the management personnel interface.

If the operation and maintenance personnel enter the work receiving personnel interface through the user name and the password, the name of the login person on the work receiving information table is automatically associated with the user name used during login. If the operation and maintenance personnel adopts a login mode of swiping a work card, fingerprint identification or face recognition, the name of the login personnel is automatically associated with the identified user name. If the same group of people can enter information through the modes of swiping a work card, fingerprint identification or face recognition, and the like, the same group of people in the reception information table can be automatically generated, otherwise, the names of the same group of people are manually input by a login person. When the content of the same group of people is empty, only the login people are on duty.

(3) The start time of the last shift is automatically associated.

Preferably, the start time of the last shift may be accurate to minutes, the start time being associated with the end time of the last shift in the last shift information table before the current time, and automatically displayed in the current shift information table.

It is assumed that the adjacent shift-exchange order shown in fig. 3 and 4 is that the start time of the last shift in the shift information table is the same as the start time of the present shift in the shift information table.

If the last shift information table before the current moment is deleted on the manager interface, the starting time of the last shift in the shift information table is automatically related to the ending time of the last shift in the new last shift information table.

(4) The end time of this shift is manually added.

As an example, taking the examples shown in fig. 3 and 4 as an example, the difference between the end time of the last shift in the shift information table and the end time of the present shift in the shift information table is the shift-shift time difference.

Preferably, the operation data in the shift information table can be automatically associated with and displayed on the relevant data in the shift information table of the last time before the current moment. If the operation and maintenance personnel on the reception of the shift find that the data change, the data can be modified according to the actual situation, wherein the ton water power consumption is automatically calculated, and the data cannot be modified.

(6) Fault maintenance information is divided into two categories

Preferably, the fault maintenance information in the shift information table can be automatically associated with and displayed on the relevant information in the shift information table of the last time before the current moment. For the contents of the solved faults and the unresolved faults, the operation and maintenance personnel of the reception can execute modification operations such as adding, deleting and the like.

(7) Damage and loss of the article and other problems can be automatically associated and displayed and modified.

Preferably, damage and loss of items in the shift information table and other problems can be automatically associated with and displayed in the last shift information table before the current moment. And, the operation and maintenance personnel of the reception can execute modification operations such as adding, deleting and the like on the content.

In a preferred embodiment, the shift information table in the shift information table and the operation data cannot be empty, otherwise, when the shift information table is stored, a prompt window is popped up in the shift personnel interface to prompt the operation and maintenance personnel to supplement the unfilled information item completely.

It should be understood that the shift man interface and the shift man interface shown in fig. 3 and 4 are only a preferred example, and in the exemplary embodiments herein, attention is focused on five parts of the contents that the operation and maintenance personnel of shift and shift need to fill in when shift is performed, namely shift information, operation data, trouble-shooting, object counting and other problems. However, because equipment facilities, treatment processes and the number and level of operation and maintenance personnel of different sewage treatment plants have great differences, the contents in the shift information table can be adjusted according to actual conditions and specific requirements of the operation and maintenance personnel of different sewage treatment plants, and the invention is not limited to the above.

Based on the shift information processing method provided by the exemplary embodiment of the invention, the current situation that shift information transmission, recording and inquiry are performed by relying on paper documents can be changed, and the problems that paper shift record forms are easy to change, damage or lose are avoided. The shift-crossing information processing method has the characteristics of accurate and reliable storage of information records, difficult manual tampering and convenience for integral searching and analysis.

Returning to fig. 1, in step S40, the amount of change between the variable information in the shift information table and the variable information in the shift information table is determined.

In the exemplary embodiment of the invention, in order to check the completion condition of the shift, the important change of the sewage treatment process or equipment during shift is accurately recorded, and the comprehensive comparison of shift information under the condition that the shift time and the shift time have time difference is realized.

Preferably, the information in the shift information table and the shift information table is divided into two types of the definite format information and the non-definite format information in the exemplary embodiment of the present invention. For determining the format information, it may be determined whether the information deviation in the shift information table and the reception information table is within an allowable range by calculating a distance (e.g., euclidean distance) of the determined format information. If the information deviation exceeds the corresponding threshold, the abnormal working process is indicated, and a reminding dialog box can be popped up on the manager interface. For non-deterministic format information, text content (e.g., words or symbols) may be directly compared. If the corresponding text contents in the shift-switching information table and the shift-switching information table are not identical, the shift-switching process is considered to be abnormal, and a reminding dialog box can be popped up on a manager interface at the moment.

As an example, the preset processing items may include a plurality of types of preset processing items, and accordingly, the determination format information may include a plurality of types of variable information acquired based on the plurality of types of preset processing items.

In this case, the amount of change is determined only for the same type of variable information, that is, the amount of change between the predetermined type of variable information in the shift information table and the predetermined type of variable information in the shift information table is determined, that is, the comparison is made for the variable information having the same type in the shift information table and the shift information table to determine the amount of change.

For example, variable information (e.g., numerical values of options or operational data) that determines format information may be represented by x. Here, the change in the value of the variable information may be due to the receipt of a new input from an operator, or the change in the collected data, or may be due to the time-varying characteristics of the variable information. Based on this, the value of the variable information of the determination format information at the time t can be expressed as x (t).

If it is assumed that at shift time t ₁ The variable information of (a) is x (t) ₁ ) At the moment t of reception ₂ The variable information of (2) is y (t) ₂ )，x(t ₁ ) And y (t) ₂ ) For the same type of variable information, the variable information x (t ₁ ) And y (t) ₂ ) Distance between them |x (t ₁ )-y(t ₂ ) The i is determined as the amount of change between the two.

In the first case, the preset processing items may include processing items in the form of numerical values.

The numerical processing item may include a plurality of operation parameter items for reflecting an operation state of the sewage treatment plant, and the variable information may include a numerical variable acquired based on the plurality of operation parameter items.

In this case, the amount of change corresponding to the numerical form variable may refer to a distance between the numerical form variable acquired based on the predetermined operation parameter item in the shift information table and the numerical form variable acquired based on the predetermined operation parameter item in the shift information table.

Taking the examples shown in fig. 3 and 4 as an example, the water inflow amount in the reception information table and the water inflow amount in the shift information table can be compared, and the distance between the two numerical form variable information can be determined as the variation.

In the second case, the preset processing items may further include processing items in a non-numeric form.

In this case, it is necessary to convert variable information in a non-numeric form corresponding to a processing item in a non-numeric form into variable information in a numeric form that can be compared to perform quantitative comparison.

Fig. 5 shows a flowchart of the steps of determining the amount of change corresponding to a non-numeric form variable according to an exemplary embodiment of the present invention.

Referring to fig. 5, in step S501, a shift code value corresponding to a non-numeric form variable acquired based on a non-numeric form processing item in a shift information table is determined.

In step S502, shift code values corresponding to the non-numeric form variables acquired based on the non-numeric form processing items in the shift information table are determined. Here, the non-numeric form variable may be processed using various methods to obtain a corresponding encoded numeric value.

In step S503, the distance between the shift code value and the shift code value is determined as the amount of change corresponding to the non-numerical form variable.

In one example, the non-numerical form of the treatment item may include a plurality of fault handling items for reflecting a fault maintenance status of the sewage treatment plant, and the variable information may include a non-numerical form variable acquired based on the plurality of fault handling items.

In this case, the reception code value may be a reception code value corresponding to a non-numerical form variable acquired based on a predetermined fault handling item in the reception information table. The shift code value may be a shift code value corresponding to a non-numerical form variable acquired based on a predetermined fault handling item in a shift information table.

In a preferred embodiment, the plurality of fault handling items may be processing items in the form of options. As an example, the processing item in the form of an option may include a plurality of predetermined fault type options and a plurality of predetermined fault level options.

The shift information processing method of a sewage treatment plant according to an exemplary embodiment of the present invention may further include: the natural number is used for encoding each fault treatment item or a combination item formed by combining at least two fault treatment items in advance.

In this case, the shift code value may be a natural number corresponding to a predetermined trouble handling item in the shift information table, and the shift code value may be a natural number corresponding to a predetermined trouble handling item in the shift information table.

Taking the examples shown in fig. 3 and 4 as an example, the non-numerical processing items in the shift information table and the reception information table are the fault type option and the fault level option of the fault maintenance section. For example, for a fault type option, the natural number may be used to encode in the following manner: for each fault type option, the natural number 0 indicates that each fault type option is not selected, the natural number 1 indicates that the self-control option is selected, the natural number 2 indicates that the electrical option is selected, the natural number 3 indicates that the mechanical option is selected, the natural number 4 indicates that the heating and ventilation lighting option is selected, and the natural number 5 indicates that the infrastructure option is selected. For each fault level option, the natural number 0 indicates that none of the fault level options is selected, the natural number 1 indicates that the level I (slight) option is selected, the natural number 2 indicates that the level II (medium) option is selected, and the natural number 3 indicates that the level III (serious) option is selected. It should be appreciated that the above-described manner of encoding the processing items in the form of options using natural numbers is merely an example, and that other manners of encoding may be employed.

In another example, the non-numeric form of the processing item may further include a plurality of alphabetic forms of the processing item.

In this case, the shift-receiving code value may be an ASCII code value corresponding to a letter corresponding to a processing item in a predetermined letter form in the shift information table, and the shift-changing code value may be an ASCII code value corresponding to a letter corresponding to a processing item in a predetermined letter form in the shift information table.

At this time, the variable amount corresponding to the non-numerical form variable may refer to a distance between an ASCII code value corresponding to a letter corresponding to a processing item of a predetermined letter form in the shift-by-shift information table and an ASCII code value corresponding to a letter corresponding to a processing item of a predetermined letter form in the shift-by-shift information table.

Returning to fig. 1, in step S50, it is determined whether there is an abnormality in the shift-on process according to the determined variation amount and the threshold set.

As an example, the set of thresholds may include thresholds corresponding to a plurality of operating parameter items. In this case, the change amounts corresponding to the same type of numerical form variables in the shift-change information table and the shift-change information table may be compared with the threshold value corresponding to the type of operation parameter item, and when the change amount is greater than the threshold value, it is determined that there is an abnormality in the shift-change process, and when the change amount is less than or equal to the threshold value, it is determined that there is no abnormality in the shift-change process.

In addition to the above-described manner of comparing according to the type of the preset processing item, a manner of comparing the entirety of the determined format information in the shift-exchange information table and the shift-exchange information table may be adopted to determine whether there is an abnormality in the shift-exchange process.

As an example, the set of thresholds may further include a total threshold corresponding to the determined format information. In this case, the total amount of change of the determined format information in the shift-change information table and the shift-change information table may be determined, and whether or not there is an abnormality in the shift-change process may be determined based on the result of comparing the total change with the total threshold.

Here, the amount of change corresponding to each type of numerical form variable and the amount of change corresponding to each type of non-numerical form variable may be calculated separately, and the sum of all the amounts of change calculated may be determined as the total amount of change of the determination format information. In addition, the total variation of the format information can be directly obtained based on all types of numerical and non-numerical variables, which will be described in detail later.

Fig. 6 illustrates a flowchart of a shift information processing method of a sewage treatment plant according to another exemplary embodiment of the present invention.

Referring to fig. 6, in step S100, a shift time difference between the shift time and the shift time is determined.

In step S200, a set of thresholds corresponding to the shift time difference is determined.

Here, it should be understood that step S100 and step S200 in fig. 6 are the same as step S10 and step S20 in fig. 1, and the present invention will not be repeated for this part of the content.

In step S300, it is determined whether or not all the numerical form variables are abnormal.

As an example, the set of thresholds may include thresholds corresponding to a plurality of operating parameter items.

In a preferred embodiment, it is determined whether there is an abnormality in the numerical form variable acquired based on any of the operating parameter items in the following manner.

Calculating the distance between a numerical form variable acquired based on any operation parameter item in the shift information table and a numerical form variable acquired based on any operation parameter item in the shift information table, comparing the calculated distance with a threshold corresponding to any operation parameter item, determining that the numerical form variable acquired based on any operation parameter item is abnormal if the calculated distance is larger than the threshold corresponding to any operation parameter item, and determining that the numerical form variable acquired based on any operation parameter item is not abnormal if the calculated distance is smaller than or equal to the threshold corresponding to any operation parameter item.

Here, the abnormality determination can be made on the numerical form variable acquired for each operation parameter item in the above-described manner.

If there is an abnormality in the numerical form variable acquired based on any one of the operation parameter items, step S400 is performed: generating warning information for prompting the abnormality of the numerical form variable acquired based on any operation parameter item.

For example, the generated alert information may be displayed in a manager interface.

If no exception exists in all the numerical form variables, step S500 is performed: and judging whether the solved fault level in the shift-change information table and/or the shift-connection information table is the highest level.

For example, taking the example shown in fig. 3 and 4 as an example, it may be determined in step S500 whether the resolved failure level of the shift information table and/or the reception information table is level III.

If the resolved failure level is the highest level in any one of the shift-to-shift information table and the shift-to-shift information table, step S600 is performed: and displaying the faults solved by the fault maintenance.

For example, a dialog box may be flicked out in the manager interface or a fault in which the fault maintenance part has been solved in the shift information table and the reception information table may be highlighted.

If the resolved failure level in both the shift-to-shift information table and the shift-to-shift information table is not the highest level, step S700 is performed: and determining the total variation of the format information according to the variation between the variable information of various types in the shift information table and the variable information of various types in the shift information table.

The process of directly obtaining the total variation of the determination format information based on all types of numerical form variables and non-numerical form variables is described below.

For example, a determination format information vector may be created for the shift information table and the shift information table, respectively, and as an example, the determination format information vector X may be expressed as x= (X) ₁ ,x ₂ ,…,x _n ) Wherein the variable x _i And (1) i is equal to or less than n, and is a coded numerical value corresponding to a numerical value form variable or a non-numerical value form variable. In a deterministic format information vector, the variable x _i And variable x _j The variables may be the same type or different types.

As an example, the threshold set may further include correction coefficients corresponding to various types of variable information.

In this case, the step of determining the total variation of the determination format information may include: the total variation of the format information is determined according to the variation between the variable information of the plurality of types in the shift information table and the correction coefficient corresponding to the variable information of the plurality of types.

In one example, suppose the shift time is t ₁ The format information vector is determined to be X (t ₁ )＝(x ₁ (t ₁ ),x ₂ (t ₁ ),…,x _n (t ₁ ) Time of reception is t ₂ ，(t ₂ ≥t ₁ ) The determined format information vector created for the shift information table is Y (t ₂ )＝(y ₁ (t ₂ ),y ₂ (t ₂ ),…,y _n (t ₂ ))。

As an example, a determination format information vector X (t ₁ ) And determining the format information vector Y (t ₂ ) The Euclidean distance between the two images is determined as the total variation of the format information.

For example, the determination format information vector X (t ₁ ) And Y (t) ₂ ) In time period t ₂ -t ₁ Distance of Europe above:

/>

in the formula (1), c _i Representing the correction coefficient corresponding to the i-th variable. Here, the variable x _i (t ₁ ) And y is _i (t ₂ ) The same type of variable information is necessary.

It should be appreciated that the correction coefficients in the above formula for calculating the euclidean distance of the format information vector may be set according to the needs of the user. Generally speaking, the value of the correction coefficient needs to consider both the magnitude of different variable values and the degree of interest of the user on the corresponding variable information.

In the above-described exemplary embodiment, one total euclidean distance is calculated for the determined format information vector, but the present invention is not limited thereto, and the euclidean distance may be calculated for each numerical form variable and non-numerical form variable in the determined format information of the shift information table and the shift information table, respectively, with the sum of each euclidean distance as the total variation. In addition to this, the total variation of the determination format information may be calculated in other ways than the calculation of the euclidean distance.

In step S800, the determined total variable is compared with a total threshold, i.e., it is determined whether the total variable is greater than the total threshold.

If the total variable is greater than the total threshold, step S900 is performed: and determining that abnormality exists in the shift-switching process.

In this case, a calculation process of determining the euclidean distance of the format information vector may be provided to a manager of the sewage treatment plant. For example, a calculation process of the euclidean distance determining the format information vector is displayed on a manager interface of the sewage treatment plant.

If the total variable is not greater than (i.e., less than or equal to) the total threshold, step S1100 is performed: and determining that no abnormality exists in the shift-switching process.

In this case, the manager of the sewage treatment plant may be provided with unsolved contents of the trouble-shooting part, damaged and lost contents of the article counting part, and other problems in the shift information table.

For example, a dialog box may be popped up or the unresolved content of the failed repair section, the damaged and lost content of the inventory section, other issues in the shift information table and the reception information table may be highlighted in the manager interface.

In a preferred embodiment, the shift information table and the reception information table may each further include non-deterministic format information. As an example, the non-deterministic format information may include text content, e.g., information entered in text form in a shift man interface or a shift catcher interface.

In this case, the shift information processing method of a sewage treatment plant according to an exemplary embodiment of the present invention may further include: and judging whether the text content in the shift information table is consistent with the text content in the shift information table.

At this time, whether the shift-over process is abnormal or not can be determined according to the determined variation, the threshold set and the judgment result of the text content.

For example, whether the shift information table is consistent with the format information determined in the shift information table may be determined based on the comparison result of the total variation of the format information determined and the total threshold value in the above manner, and whether the shift information table is consistent with the format information not determined in the shift information table may be determined based on the determination result of the consistency of the text content in the shift information table and the text content in the shift information table. When it is determined that the format information is consistent (i.e., the total variation is less than or equal to the total threshold) and that the non-determined format information is consistent (i.e., the text content is consistent), it is determined that there is no abnormality in the shift-over process, and when it is determined that the format information is inconsistent (i.e., the total variation is greater than the total threshold) and/or that the non-determined format information is inconsistent (i.e., the text content is inconsistent), it is determined that there is an abnormality in the shift-over process.

In one embodiment, it is assumed that two preset threshold sets p are preset ₁ And p ₂ The preset shift time difference corresponding to the two preset threshold sets is respectively 10 minutes and 30 minutes. Taking the examples shown in fig. 3 and 4 as an example, the shift time difference is 8 minutes, so that the preset threshold value set p corresponding to the preset shift time difference of 10 minutes can be selected ₁ As a set of thresholds corresponding to 8 minute shift time differences.

Assuming that the selected set of thresholds includes p ₁ The threshold value corresponding to the plurality of operation parameter items (i.e., the threshold value corresponding to the plurality of types of variable information), the total threshold value of the determination format information, and the correction coefficient corresponding to the different types of variable information are shown in table 1.

TABLE 1

Taking the examples shown in fig. 3 and fig. 4 as examples, for each operation parameter item, calculating the distance between the numerical form variable in the shift information table and the numerical form variable in the shift information table, and comparing the distances with the corresponding threshold value to obtain the single shift data, wherein the distances between the single shift data are smaller than the corresponding threshold value, so that the single shift data do not have excessive fluctuation during shift, and the shift requirement is met.

And (3) calculating the Euclidean distance of the format information vector by using the formula (1), and obtaining that the total variation between the format information in the shift-over information table and the format information in the shift-over information table is 2.88, wherein the total variation is smaller than a total threshold value of 5.26, which indicates that the total variation of the format information is determined to be within an allowable range during shift-over. And, the resolved failure level does not reach level III, indicating that the failure has been confirmed by the operator who is on duty, despite the unresolved failure that the oxidation ditch level gauge is not consistent with the central room level indication. Finally, articles of the sewage treatment plant are not damaged or lost, and other carry-over problems are avoided. The operation and maintenance personnel are indicated to normally carry out the shift switching process, and a prompt dialog box is not popped up in an administrator interface or relevant contents in a shift switching information table and a shift switching information table are highlighted.

In a preferred embodiment, the manager interface may further be provided with a query page for the stored shift information table and the shift information table. Through the query page, a manager of the sewage treatment plant can search and delete the shift information table and the shift information table in all or a designated time period. When the stored last shift information table or shift receiving information table is deleted, the start time in the newly generated shift information table or shift receiving information table is automatically associated with the end time of the last shift in the last shift receiving information table before the current moment. The automatic association operation described above may not be performed in the case where the shift information table or the reception information table that is not the last time is deleted.

As an example, the function of querying the shift information table and the reception information table within the specified period may be implemented by setting the query start time and the query end time on the query page. For the case where the shift information table and the shift information are stored in the SQL database, the query of the stored shift information table and shift information table may be achieved by associating the query conditions on the query page with the SQL query language.

In the exemplary embodiment of the invention, the shift-over information table and the shift-over information table are stored by applying the SQL database, and a plurality of inquiry conditions are set on the inquiry page, so that flexible inquiry and display of the shift-over information table and the shift-over information table can be realized.

Preferably, on the query page, in addition to the query start time and the query end time, search query conditions for different data items are set, so that a multi-conditional query can be implemented. For example, when the query option of destroying and losing the object counting part is selected, and the query starting time and the query ending time are selected, the destroying and losing condition of the object counting part during each shift in the appointed time period can be searched out from the SQL database.

As shown in fig. 7, the shift information processing apparatus of a sewage treatment plant according to an exemplary embodiment of the present invention includes: the shift-on time difference determining unit 10, the threshold determining unit 20, the shift-on information table acquiring unit 30, the variation determining unit 40, and the abnormality judging unit 50.

Specifically, the shift time difference determination unit 10 determines the shift time difference between the shift time and the shift time.

The threshold value determining unit 20 determines a threshold value set corresponding to the shift-on time difference.

The shift information processing apparatus of a sewage treatment plant according to an exemplary embodiment of the present invention may further include: and a correspondence determining unit (not shown in the figure) that presets correspondence between a plurality of preset shift time differences and a plurality of preset threshold sets.

In this case, the threshold determining unit 20 may search for a preset shift time difference larger than the shift time difference from among a plurality of preset shift time differences, determine the smallest preset shift time difference among the searched preset shift time differences, and determine a preset threshold set corresponding to the smallest preset shift time difference as the threshold set.

The shift information table acquisition unit 30 acquires a shift information table at shift time and a shift information table at shift time. Here, the shift-shift information table and the shift-reception information table each include determination format information including variable information acquired based on a preset processing item.

The change amount determination unit 40 determines the change amount between the variable information in the shift information table and the variable information in the shift information table.

Here, the preset processing items may include a plurality of types of preset processing items, and accordingly, the determination format information may include a plurality of types of variable information acquired based on the plurality of types of preset processing items.

At this time, the change amount determination unit 40 may determine the change amount between the predetermined type of variable information in the shift information table and the predetermined type of variable information in the shift information table.

As an example, the treatment item in the form of a numerical value may include a plurality of operation parameter items for reflecting the operation state of the sewage treatment plant, and accordingly, the variable information may include a numerical value form variable acquired based on the plurality of operation parameter items.

In this case, the amount of change corresponding to the numerical form variable may refer to a distance between the numerical form variable acquired based on the predetermined operation parameter item in the shift-by-shift information table and the numerical form variable acquired based on the predetermined operation parameter item in the shift-by-shift information table.

In the second case, the preset processing items may include processing items in a non-numeric form.

In one example, the non-numerical form of the processing item may include an option form of the processing item.

For example, the non-numerical form of the treatment item may include a plurality of fault handling items for reflecting a fault maintenance state of the sewage treatment plant, and accordingly, the variable information may include a non-numerical form variable acquired based on the plurality of fault handling items. As an example, the processing item in the form of an option may include a plurality of predetermined fault type options and a plurality of predetermined fault level options.

The change amount determination unit 40 may determine a shift code value corresponding to a non-numerical form variable acquired based on a predetermined fault handling item in the shift information table, and determine a distance between the shift code value and the shift code value as a change amount corresponding to the non-numerical form variable.

Preferably, the shift information processing apparatus according to the exemplary embodiment of the present invention may further include: an encoding unit (not shown in the figure) encodes each of the trouble items or a combination item formed by combining at least two trouble items in advance using a natural number.

In this case, the variable amount corresponding to the non-numerical form variable may refer to a distance between an ASCII code value corresponding to a letter corresponding to a processing item of a predetermined letter form in the shift-by-shift information table and an ASCII code value corresponding to a letter corresponding to the processing item of the predetermined letter form in the shift-by-shift information table.

The abnormality determination unit 50 determines whether there is an abnormality in the shift-on process, based on the determined variation and the threshold set.

As an example, the set of thresholds may include a total threshold corresponding to the determined format information.

In this case, the abnormality determination unit 50 may determine the total amount of change of the format information based on the amount of change between the plurality of types of variable information in the shift information table and the plurality of types of variable information in the shift information table, and determine whether there is an abnormality in the shift process based on the determined total amount of change and the total threshold.

In a preferred embodiment, the shift information processing apparatus according to an exemplary embodiment of the present invention may further include: the numerical variable judging unit 60 determines whether or not all the numerical form variables are abnormal.

As an example, the set of thresholds may further include thresholds corresponding to the plurality of operating parameter items.

Preferably, the numerical variable judging unit 60 may determine whether or not there is an abnormality in the numerical form variable acquired based on any one of the operation parameter items in the following manner.

Comparing the distance between the numerical form variable acquired based on any operation parameter item in the shift information table and the numerical form variable acquired based on any operation parameter item in the shift information table with a threshold corresponding to any operation parameter item, and if the distance is larger than the threshold corresponding to any operation parameter item, determining that the numerical form variable acquired based on any operation parameter item is abnormal. If the distance is less than or equal to the threshold value corresponding to any operation parameter item, it is determined that no abnormality exists in the numerical value form variable acquired based on any operation parameter item.

For example, if the numerical variable judging unit 60 determines that there is no abnormality in all the numerical form variables, the abnormality judging unit 50 determines the total amount of change of the determination format information based on the amount of change between the variable information of the plurality of types in the shift information table and the variable information of the plurality of types in the shift information table.

If the numerical variable judging unit 60 determines that there is an abnormality in the numerical form variable acquired based on any one of the operation parameter items, the abnormality judging unit 50 generates warning information for prompting the presence of an abnormality in the numerical form variable acquired based on the any one of the operation parameter items.

At this time, the abnormality determining unit 50 may determine the total variation of the determination format information based on the variation between the variable information of the plurality of types in the shift information table and the variable information of the plurality of types in the shift information table, and the correction coefficient corresponding to the variable information of the plurality of types.

For example, the abnormality determination unit 50 may compare the determined total variable with a total threshold, determine that there is no abnormality in the shift process if the determined total variable is less than or equal to the total threshold, and determine that there is an abnormality in the shift process if the determined total variable is greater than the total threshold.

In a preferred embodiment, the shift-to-shift information table and the reception information table may each include non-deterministic format information in addition to deterministic format information, which may include text content, as an example.

Preferably, the shift information processing apparatus according to the exemplary embodiment of the present invention may further include: the text content judgment unit 70 judges whether or not the text content in the shift information table matches the text content in the shift information table.

In this case, the abnormality determination unit 50 may determine whether there is an abnormality in the shift-over process based on the determined amount of change, the threshold set, and the determination result of the text content.

There is also provided, in accordance with an exemplary embodiment of the present invention, a computing device. The computing device includes a processor and a memory. The memory is used for storing a computer program. The computer program is executed by the processor to cause the processor to execute the shift information processing method of the sewage treatment plant described above.

There is also provided, in accordance with an exemplary embodiment of the present invention, a computer-readable storage medium storing a computer program. The computer-readable storage medium stores a computer program that, when executed by a processor, causes the processor to execute the shift information processing method of the sewage treatment plant described above. The computer readable recording medium is any data storage device that can store data which can be read out by a computer system. Examples of the computer-readable recording medium include: read-only memory, random access memory, compact disc read-only, magnetic tape, floppy disk, optical data storage device, and carrier waves (such as data transmission through the internet via wired or wireless transmission paths).

By adopting the shift-crossing information processing method and device of the sewage treatment plant, which are disclosed by the embodiment of the invention, the information management level of shift-crossing of operation and maintenance personnel of the sewage treatment plant can be effectively improved, management personnel of the sewage treatment plant can be helped to know and discover possible problems in the shift-crossing process in time, and the problem disposal condition can be tracked timely and accurately so as to achieve the purposes of strengthening management and auxiliary decision making.
