In particular, the registration processing unit 421 executes different medium information registration processing based on flag information indicating whether the registration is initial registration or post-culture registration included in the culture medium information.

(Initial registration)
When the flag information indicating the initial registration is included in the culture medium information transmitted from the portable communication terminal device 10, the registration processing unit 421 executes a registration process based on the initial registration.

  Specifically, when the registration processing unit 421 acquires the culture medium information via the communication control unit 410, the registration processing unit 421 specifies the work ID 71. In addition, the registration processing unit 421 searches the work management DB 404 based on the specified work ID 71, specifies the corresponding work information, and associates the acquired medium image data and imaging time with the specified work information.

The culture medium image data and the imaging time included in the culture medium information are registered in the culture medium information DB 401 while giving a unique culture medium ID in association with the lot ID, the line ID, and the process ID 71b.

  Note that the registration processing unit 421 registers the imaging time as the culture start time in the culture medium information DB 401. Further, as the culture start time, a preset time may be used instead of the imaging time on the assumption that the medium information registration process is executed at the time.

(Registration after culture)
When the flag information indicating post-cultivation registration is included in the culture medium information transmitted from the portable communication terminal device 10, the registration processing unit 421 performs a registration process based on post-cultivation registration.

  Specifically, when the medium processing information is acquired via the communication control unit 410, the registration processing unit 421 specifies the work ID 71 included in the medium information, as in the initial registration. Then, the registration processing unit 421 searches the work management DB 404 based on the specified work ID 71, specifies the corresponding work information, and associates the medium image data and the imaging time with the specified work information. Register in the information DB 401. Note that the culture examination time may be a preset time instead of the imaging time on the assumption that the culture information registration process is executed at the same time as the culture start time.

  Further, the registration processing unit 421 causes the colony detection determination unit 423 to execute the colony detection determination process based on the acquired medium information, and specifies the colony information, the number of colonies, and the determination result acquired by executing the colony detection determination process as the medium information. The medium ID DB 401 is registered in association with the work ID 71.

[5.3] Colony Detection Determination Unit Next, the operation principle of the colony detection determination unit 423 in the server device 40 of the present embodiment will be described.

The colony detection determination unit 423 performs the colony detection determination process as follows:
(A) In order to detect pixels that are supposed to form an imaged colony from the culture medium image, pixels having a feature amount relating to a color having a predetermined condition from among the pixels configuring the culture medium image ( Hereinafter referred to as “colony pixel”)
(B) Link colony pixels based on a predetermined condition, execute labeling to give an ID, detect a connected colony pixel group as one colony candidate,
(C) While identifying colony candidates having a predetermined condition as colonies, the number is counted,
(D) The medium determination is executed based on the counted number of colonies.

  Specifically, the colony detection determination unit 423 is based on the work ID 71 specified by the registration processing unit 421 and, if necessary, information included in the culture medium information acquired by the registration processing unit 421. The work information DB 404 or, if necessary, information stored in another database is searched to obtain the corresponding work information.

In addition, the colony detection determination unit 423 is based on the conditions for detecting colonies such as the type of specimen, the bacterial species, the culture time, and the culture conditions included in the acquired work information.
(1) Type of characteristic amount related to color when colony pixels are detected from the medium image,
(2) A detection method for detecting a colony based on the type of (1), a parameter for executing the detection, and
(3) Threshold value for pass / fail when performing medium determination,
Is specified from a plurality of profiles stored in the ROM / RAM 430.

  The colony detection determination unit 423 sets colony pixel detection methods, colony candidate detection methods, colony specification methods, and medium determination methods while setting various thresholds or parameters based on the specified profile. Execute the process.

  In particular, when the type of feature quantity is luminance or saturation, the colony detection determination unit 423 obtains a value obtained by executing a predetermined calculation based on the gradation value of each RGB sub-pixel of each pixel. And detecting colony pixels based on the parameters defined in the profile, identifying colony candidates based on the detected colony pixels, detecting colonies from the identified colony candidates, and counting the number .

  For example, when the colony pixel detection method defined in the profile uses “binarization”, the colony detection determination unit 423 binarizes the feature amount defined in the profile with the threshold defined in the profile. Then, a pixel having one value is detected as a colony pixel.

  The colony detection determination unit 423 performs labeling by connecting adjacent colony pixels while performing image filter processing including expansion processing and reduction processing for reducing image filter noise, and assigning an ID. Colony candidates are detected based on the linking method and its parameters.

  That is, the colony detection determination unit 423 is configured to connect the colony pixels with respect to adjacent colony pixels based on a range that should be determined to be the same as the feature amount related to the color of each colony pixel specified by the profile. Concatenate those determined to be.

  In addition, the colony detection determination unit 423 connects adjacent colony pixels to form a colony pixel group, and uses the color characteristics for each colony pixel group or the barycentric position on the medium image to form the same colony pixel Connect them together.

  Then, the colony detection determination unit 423 calculates a likelihood indicating the likelihood of colony based on features such as color characteristics, roundness, shape, and size for each detected colony candidate, and the likelihood is equal to or greater than a threshold value. A colony candidate having a predetermined condition such as the above is specified as a colony and the count is executed.

  Furthermore, the colony detection determination unit 423 determines whether the specimen of each film-type medium 60 is abnormal or normal based on the threshold set based on the acquired profile and the detected number of colonies (that is, Sample pass / fail determination) is executed.

  The colony detection determination unit 423 detects the detected colony pixel (for example, the position on the medium image and the ID of the colony candidate to which the own pixel belongs), the detected colony candidate (for example, the arrangement position of the colony pixel on the medium image, the color characteristic, or Registration processing of specified information such as the center of gravity position), the identified colonies (for example, predetermined information such as the arrangement position of colony pixels on the medium image, color characteristics or the position of the center of gravity), the number of colonies counted and the medium determination result as medium information The information is stored in the culture medium information DB 401 via the unit 421.

  In addition, the expansion process is one of image filter processes, and is a process of replacing all pixels adjacent to a colony pixel with colony pixels when other colony pixels exist adjacent to each colony pixel. .

  Further, the contraction process is a process of replacing all pixels adjacent to the colony pixel with non-colony pixels when there is a non-detected pixel adjacent to the colony pixel (hereinafter referred to as “non-colony pixel”). .

[5.4] Lot Determination Processing Unit Next, details of the lot determination processing unit 424 in the server device 40 of the present embodiment will be described.

  The lot determination processing unit 424 of the present embodiment analyzes data on hygiene management in the designated lot, work line 80 or process based on the instructions of the administrator input to the administrator terminal device 20 (ie, pass / fail determination). Execute.

  Specifically, the lot determination processing unit 424, for each lot, line information of the work line 80 used for the corresponding lot, and medium information registered in association with the corresponding work line 80 (at least the number of colonies). Based on the above, it is determined whether the food group manufactured or inspected under the same condition has a predetermined condition.

  In addition, when the lot determination is instructed, the lot determination processing unit 424 determines whether the work line 80 included in the corresponding lot and the processes belonging to the work line 80 are abnormal or normal in terms of hygiene management. 80 line determinations (that is, pass / fail determination for hygiene management) and process determinations for each process (that is, determination of pass / fail for hygiene management) are performed, and lot determination is performed using the process determination and line determination.

  In particular, when the lot determination is instructed, the lot determination processing unit 424, for example, the number of colonies of the film-type medium 60 in the medium information that has passed a predetermined culture inspection time such as 24 hours or 48 hours from the start of culture, Based on the medium information of the pass / fail determination of the specimen, the pass / fail of hygienic management of the process is determined, and the pass / fail of hygiene management of the work line 80 is determined based on the pass / fail determination of the process included in the corresponding work line 80. Based on the pass / fail determination of the work line 80 included in the corresponding lot, the pass / fail in sanitary management of the lot is determined.

  Note that the lot determination processing unit 424 of the present embodiment may execute not only lot determination but also process determination or line determination as data analysis.

(Process judgment)
The lot determination processing unit 424 has a culture start time at the same timing, a culture examination time at the same timing, a culture start time having a time within a preset time from the first time to the second time, or a preset first time. The culture start time or the culture test time has a predetermined condition, such as having a culture test time having a time within the time from the first time to the second time, and is registered in association with the same process in the same lot. Each process determination is performed based on the culture medium information of the plurality of film-type culture media 60 that has been performed. That is, the lot determination processing unit 424 executes each process determination by comprehensive determination based on each medium determination result of the plurality of film-type mediums 60.

  Specifically, the lot determination processing unit 424 displays the medium determination results of the corresponding film-type medium 60 (that is, all the medium determination results registered in the medium information having the process ID 71b of the process to be subjected to the process determination). In addition to obtaining, if the number of pass / fail of the judgment result satisfies a predetermined condition, the process judgment of the process to be judged is judged to be acceptable, and if not, the judgment should be made The process judgment of the process is judged as rejected.

  For example, the lot determination processing unit 424 determines that the conditions for all the film-type culture media 60 when the acceptable film-type culture media 60 are a predetermined ratio (60%) or more in the individual film-type culture media 60 in the corresponding process ( The number of colonies is equal to or less than a certain number), or the condition that the number of colonies of each film-type medium 60 corresponds (the average number of colonies of a single film-type medium 60 is equal to or less than a certain number). In this case, the corresponding process is determined to be acceptable.

  Note that the lot determination processing unit 424 of the present embodiment can change conditions depending on the type of specimen, the type of bacteria to be detected, etc., and can be set by an administrator or provided as part of a program. The

(Line judgment)
The lot determination processing unit 424 performs line determination for each work line 80 based on the pass / fail determination for hygiene management of a plurality of processes that are determined at a predetermined timing and registered in association with the corresponding line information. To do. That is, the lot determination processing unit 424 performs line determination by comprehensive determination based on the determination results of a plurality of processes of the same lot determined at a predetermined timing.

  Specifically, the lot determination processing unit 424 is determined at the same timing or a timing satisfying a predetermined condition, and has the line ID of the work line 80 to be subjected to line determination as described above. When the determination result of the determination is acquired and the number of pass / fail of the determination result satisfies a predetermined condition, the line determination of the work line 80 to be determined is determined to be acceptable, and the condition is not satisfied The line determination of the work line 80 to be determined is determined to be unacceptable.

  For example, when the three processes have the line ID of the work line 80 to be determined, the first process is “pass”, the second process is “pass”, and the third process is “fail”. In the case where the work line 80 is configured from a process in which the predetermined condition is “60%”, the lot determination processing unit 424 determines that the line determination of the work line 80 to be determined is acceptable.

(Lot judgment)
The lot determination processing unit 424 executes the lot determination for each lot based on the hygiene management pass / fail determination of the plurality of work lines 80 that are determined at a predetermined timing and registered in association with the corresponding lot information. To do. That is, the lot determination processing unit 424 executes lot determination by comprehensive determination based on the determination results of the plurality of work lines 80.

  Specifically, the lot determination processing unit 424 executes the lot determination based on the pass / fail determination in the work line 80 having the lot ID of the lot for which the lot determination is to be performed.

  For example, the lot determination processing unit 424 determines that the lot determination of the lot to be determined is acceptable when the line determination is successful in 60% of the work lines 80 having the lot ID, and the three work lines 80 determine the lot to be determined. Assume that a lot ID is included. In this case, when the first work line 80 is “pass”, the second work line 80 is “pass”, and the third work line 80 is “fail”, the lot determination processing unit 424 determines the lot to be determined. It is determined that the lot determination is acceptable.

  When the lot work time is long, the lot determination may be executed by dividing the time every predetermined time (for example, 8 hours or 12 hours). In this case, when the lot determination is performed while the work is suspended, a dummy result may be used, or it may be determined that the work is being suspended.

  Specifically, the report processing unit 425 extracts necessary information from the medium information, the line information, and the lot information such as the medium image data, the number of colonies, or the medium determination result, and the extracted information and the lot determination processing unit 424. Based on the analysis result obtained by the above, report data is generated while assigning each information to the template data.

  Note that, as described above, the report processing unit 425 is configured to generate predetermined report data or browsing data in accordance with various analyzes or searches and provide the data to the administrator terminal device 20. . In other words, the report processing unit 425 can also provide medium information, process information, line information, or lot-related information specified by the search in a predetermined report format based on the received administrator's instruction. In addition, it is configured so that various information can be provided as evidence or reports in statutory inspection reports and other cases.

[5.6] Sanitary State Analysis Processing Unit Next, details of the sanitary state analysis processing unit 426 in the server device 40 of the present embodiment will be described with reference to FIGS. 6 to 8. 6-8 is a figure for demonstrating the determination process performed in the sanitary condition analysis process part 426 of this embodiment.

  The hygiene condition analysis processing unit 426 is configured to use a single or a plurality of work lines 80 as an object or one of them based on a predetermined timing such as a scheduled time including a date and a day of the week, or an instruction from an administrator. The hygiene state analysis providing process is executed while obtaining the number of colonies included in each medium information registered at each predetermined timing (that is, medium information at each culture examination time) with respect to the target object.

In particular, the hygiene condition analysis processing unit 426 performs the hygiene condition analysis providing process,
(1) Colonies registered within the evaluation period from the first timing to the second timing in the work element designated by the manager such as the date and time, work process, lot, or worker designated by the manager Based on the number, a determination process for analyzing the trend of the hygiene state of the object indicating the work lines 80 of the plurality of work lines 80, 1 or a part thereof during the evaluation period, and executing a predetermined determination; and
(2) When it is determined that the sanitary condition of the object is an abnormal trend or an improvement trend, the determination result is used as trend information to the administrator (or the corresponding administrator if there are multiple administrators). Offer processing to provide,
Execute.

  In particular, the sanitary state analysis processing unit 426 shows an abnormal tendency of the sanitary state of the object based on the latest evaluation period from the timing after executing the previous determination process to the timing when the latest medium information is registered. Or a determination process for determining whether or not there is an abnormal tendency in the previous analysis and whether or not the tendency is improved in the current analysis.

In addition, the hygiene condition analysis processing unit 426 performs determination processing as follows.
(1A) First determination process for determining whether the number of colonies in the evaluation period satisfies the determination condition, or
(1B) a second determination process for determining whether or not the change in the number of colonies during the evaluation period includes a determination condition;
Execute one of the following.

  Usually, if the change in the number of colonies (the slope of the graph) is greater than or equal to a certain value, it indicates a rapid change in the number of colonies, so that it can be identified that there is an abnormal tendency or an improvement tendency based on the change. .

  Further, from the assumption that the past number of colonies has a Gaussian distribution (normal distribution), the number of colonies belonging to a range outside the confidence interval can be identified as indicating an abnormal tendency or an improvement tendency.

  Therefore, as described above, the sanitary state analysis processing unit 426 can determine the abnormal tendency and the improvement tendency during the evaluation period by executing the first determination process or the second determination process.

  Specifically, the hygiene condition analysis processing unit 426 performs the determination process based on the change in the number of colonies in the time series acquired at predetermined timings during the evaluation period as the first determination process. As 2 determination processing, a threshold value is determined based on each colony number of the some culture medium information before an evaluation period, and determination processing is performed based on the determined threshold value and each colony number in an evaluation period.

  Note that the trend information of the present embodiment includes at least one of abnormal trend information indicating that the sanitary state of the object indicates an abnormal trend and improvement trend information indicating that the sanitary state indicates an improvement trend.

  In addition, the hygiene state analysis processing unit 426 is configured so that even if the evaluation period instructed by the administrator does not include the timing until the latest medium information is registered, the object in the evaluation period set by the administrator is displayed. Execute the judgment process.

(First determination process)
The sanitary state analysis processing unit 426 is based on a predetermined unit time, during the corresponding evaluation period (that is, during a period from a predetermined first timing to a second timing at which the latest medium information is acquired). ) Is calculated, and it is determined whether or not the calculated change in the number of colonies satisfies a predetermined determination condition during the evaluation period.

  Specifically, the hygiene condition analysis processing unit 426 generates a graph indicating the change in the number of colonies (hereinafter referred to as “change graph”) from the number of colonies at each timing during the corresponding evaluation period, and for 3 hours. The change graph f (t) is differentiated by unit time Δt such as 12 hours or 24 hours, and a differential graph (dx / dt) f (t) in the change graph is generated.

  And the hygiene condition analysis processing unit 426 has an abnormal tendency or an improvement tendency when the differential graph (dx / dt) f (t) during the corresponding evaluation period has a predetermined condition based on a predetermined threshold value. Is determined.

  In particular, the sanitary condition analysis processing unit 426 determines that the object is abnormal when the value of the evaluation period of the generated differential graph (dx / dt) f (t) exceeds a preset first threshold value. If the value of the evaluation period of the generated differential graph (dx / dt) f (t) falls below a preset second threshold value, it is determined that the object is in an improvement trend.

  That is, the sanitary condition analysis processing unit 426 has exceeded the first threshold value set in advance (the amount of change in the number of colonies) of the evaluation period of the generated differential graph (dx / dt) f (t), or By using a determination condition indicating whether the value of the evaluation period of the generated differential graph (dx / dt) f (t) is below a second threshold value set in advance, the abnormal tendency or improvement tendency of the object is determined.

  For example, when the objects are the work line A and the work line B, the hygiene state analysis processing unit 426 is based on the number of colonies of each work line acquired at a predetermined timing (1 hour) during the evaluation period. A change graph f (t) indicating the transition of the number of colonies as shown in FIGS. 6A and 6B is generated.

In addition, as shown in FIGS. 7A and 7B, the sanitary condition analysis processing unit 426 converts the generated change graph f _A (x) of the work line A into a predetermined unit time (3 hours). Based on this, the differential graph (dx / dt) f _A (x) in the change graph of the work line A is generated.

And the hygiene condition analysis processing unit 426 is as shown in FIGS. 7 (A) and (B).
(1) _A first threshold value (hereinafter referred to as “upper threshold value”) in which at least a part of the generated differential graph (dx / dt) f _A (x) in the evaluation period (the whole evaluation section in FIG. 7) is predetermined. ))), The object is determined to be abnormally prone,
(2) In the case where it is determined that there is an abnormal tendency in the previous hygiene state analysis providing process executed for the same object in the same work element, and the generated differential graph (dx / dt) f _A ( x) When a part of the section (all evaluation sections in FIG. 7) is below a predetermined second threshold (hereinafter referred to as “lower limit threshold”), the object is in an improvement trend. judge.

  FIG. 7B shows a case where an abnormal tendency is determined based on the upper limit threshold at timing A, and an improvement trend based on the lower limit threshold at timing B (that is, the evaluation period which is the latest period). Indicates that it has been determined.

  In the present embodiment, the presence or absence of a past abnormal trend used when determining an improvement trend is the determination result of the evaluation period from the time of execution of the first determination process to the previous day, the determination result of the evaluation period one week ago, or It may be a condition that it is within a predetermined period, such as the determination result of the evaluation period before one month, or the first improvement tendency was determined after the abnormal tendency determination in the past evaluation period with unlimited time As a condition. However, the sanitary condition analysis processing unit 426 does not have the determination of the abnormal tendency in the past evaluation period, or does not have the condition in which the determination result of the determined evaluation period is set even if the abnormality tendency is determined. However, even if the value falls below the lower limit threshold, it is not determined that the trend is improving.

  The sanitary condition analysis processing unit 426 determines that the target is abnormal or improving when the differential graph (the amount of change in the number of colonies) in one section during the evaluation period exceeds the upper threshold or falls below the lower limit. If the number of colonies in the film-type culture medium 60 exceeds the upper limit threshold or the lower limit value, the differential graph (the amount of change in the number of colonies) of a predetermined number such as 2 or more during the evaluation period may be determined. When it is less than the range, it may be determined that the object is in an abnormal tendency or an improvement tendency.

  If a plurality of pieces of medium information are registered for the same object (for example, the same work line 80 or a part thereof) with the same work element (for example, every day), An average value of the number of colonies included may be calculated, and the average value may be used for the determination process.

  Furthermore, when providing the trend information of abnormal tendency depending on the level, the hygiene state analysis processing unit 426 sets a plurality of thresholds, determines which threshold is exceeded, and determines the level of abnormal tendency. Also good.

(Second determination process)
The sanitary state analysis processing unit 426 acquires the number of colonies of the plurality of medium information before the evaluation period, determines the upper limit value or the lower limit value of the number of colonies as a threshold based on the number of colonies, and based on the determined threshold value Then, it is determined whether the number of colonies during the evaluation period satisfies the determination condition.

In particular, the hygiene condition analysis processing unit 426
(1) As the change in the number of colonies during the evaluation period, the amount of change in the number of colonies during the evaluation period is calculated,
(2) It is determined whether or not the calculated amount of change in the number of colonies satisfies the determination condition.

  Specifically, the sanitary state analysis processing unit 426 changes the number of colonies as shown in FIG. 6A from the number of colonies at each timing during the corresponding evaluation period, as in the first determination process. Generate a graph.

  In addition, as shown in FIG. 8A, the sanitary state analysis processing unit 426 calculates the average value and the variance value from the number of colonies of the plurality of pieces of medium information in a predetermined period before the evaluation period, Based on a predetermined confidence interval (for example, 95% or 99%) centered on the average number of colonies, the range of the confidence interval of the number of colonies based on the average value is calculated and shown in FIG. 8B. As described above, the upper limit value and the lower limit value colony number of the calculated confidence interval are determined as the upper limit threshold value (that is, the upper limit threshold value) and the lower limit threshold value (that is, the lower limit threshold value), respectively.

And as shown in FIG. 8 (B), the sanitary condition analysis processing unit 426
(1) When the number of colonies in the evaluation period exceeds the upper limit threshold, it is determined that the object is in an abnormal tendency,
(2) In the case where the number of colonies in the evaluation period is below the determined lower threshold value, an abnormal tendency is detected in the previous determination process while reading past trend information in the same work element stored in the trend information DB 405. If it is determined that there is, it is determined that there is an improvement trend.

  That is, the sanitary condition analysis processing unit 426 uses the judgment condition as to whether or not the number of colonies of each film-type medium 60 in the evaluation period exceeds the upper limit value or lower than the lower limit value. An abnormal tendency or an improvement tendency is determined.

  In addition, the sanitary condition analysis processing unit 426 determines that the object is in an abnormal tendency or an improvement tendency when the number of colonies in one film-type medium 60 during the evaluation period exceeds the upper limit threshold or falls below the lower limit. Alternatively, when the number of colonies in the film-type medium 60 of a predetermined number or more such as 2 or more during the evaluation period exceeds the upper limit threshold value or falls below the lower limit value, the object tends to be abnormal or improved. You may determine that there is.

  For example, when the object is the work line A, the sanitary state analysis processing unit 426 counts the number of colonies of each work line acquired at each predetermined timing (1 hour) during the evaluation period, as in the first determination process. Based on the above, a change graph f (t) indicating the transition of the number of colonies is generated.

  Further, the hygiene condition analysis processing unit 426 calculates the average value X and the variance from the number of colonies in the plurality of pieces of medium information in the entire period before the evaluation period or in the past January, as shown in (Expression 1) and (Expression 2). The value S is calculated. Then, as shown in (Equation 3), the hygiene condition analysis processing unit 426 is based on a predetermined confidence interval (for example, 95% or 99%) centered on the number of samples n and the average number X of colonies. Then, the confidence interval of the number of colonies based on the average value X is calculated, and the upper limit value and the lower limit value of the calculated confidence interval are determined as the upper limit threshold value and the lower limit threshold value, respectively.

“Α” indicates ((100−confidence interval%) / 100), and “x _i ” indicates the number of colonies. “T” is a continuous probability distribution and is a value calculated from the t distribution used when estimating the average of a population having a Gaussian distribution when the number of samples is small, and the confidence interval is 95%. Indicates “0.262”, and when the confidence interval is 99%, indicates “0.3250”.

  Similarly to the first determination process, the presence or absence of a past abnormal tendency used when determining the improvement tendency is determined as the determination result of the evaluation period from the execution of the first determination process to one day before, the evaluation one week before It may be a condition that it is within a predetermined period, such as the determination result of the period or the evaluation period of the previous month, or the first improvement trend after the abnormal trend determination in the past evaluation period with unlimited time It may be a condition that the determination is made. However, the sanitary condition analysis processing unit 426 does not have the determination of the abnormal tendency in the past evaluation period, or does not have the condition in which the determination result of the determined evaluation period is set even if the abnormality tendency is determined. However, even if the value falls below the lower limit threshold, it is not determined that the trend is improving.

  Then, as in the first determination process, when the work element is every day and a plurality of pieces of medium information are registered for the same object, the number of colonies included in each piece of medium information An average value may be calculated and the average value may be used for the determination process.

  Furthermore, similarly to the first determination process, the sanitary state analysis processing unit 426 provides a plurality of threshold values when determining the trend information of abnormal tendency depending on the level, and determines which threshold value has been exceeded. The level of the abnormal tendency may be determined, and in this case, the providing process described later may be changed according to the level of the abnormal tendency.

(Provision processing)
When the sanitary condition analysis processing unit 426 determines that the sanitary condition of the target object such as the work line 80 or a part thereof is abnormal tendency by the first determination process or the second determination process, the determination result is managed as the trend information. Providing processing to a manager (or a corresponding manager if there are a plurality of managers) by a predetermined method, such as providing to the person terminal device 20.

  Specifically, when the sanitary condition analysis processing unit 426 determines that the sanitary condition of the target object is abnormal, the hygiene condition analysis processing unit 426 performs warning display on the administrator terminal device 20 via e-mail or a predetermined application. Send the data and provide a notice to that effect.

  In addition, after the sanitary condition analysis processing unit 426 determines that the sanitary condition of the object is in an abnormal tendency by the first determination process or the second determination process, the sanitary condition of the object is improved and is in an improving trend. If it is determined, data for executing the improvement display is transmitted to the administrator terminal device 20 via e-mail or a predetermined application, and this is provided.

  In particular, the sanitary condition analysis processing unit 426 generates image data for displaying data regarding an abnormal tendency and an improvement tendency on the administrator terminal device 20 according to the settings of the administrator and the like, and the generated image data is used as the administrator terminal. It is transmitted to the device 20 together with data for performing warning display or improvement display.

  The hygiene condition analysis processing unit 426 may provide the improvement tendency only when the administrator sets the determination result of the improvement tendency. In other words, the sanitary condition analysis processing unit 426 provides the administrator with the fact only when the administrator requests provision of an improvement tendency and determines that the improvement tendency is present.

  In addition, when the hygiene condition analysis processing unit 426 provides the trend information of the abnormal tendency according to the level of the abnormal tendency (hereinafter referred to as “abnormal tendency level”), the abnormality of the trend information such as job title and number of persons Providing trend information is performed by changing or adding providing means such as an administrator, an email, an alarm, and a work line stop according to the trend level. For example, when the abnormal tendency level is the lowest level (mild abnormal tendency), the hygiene condition analysis processing unit 426 provides only to the manager terminal device 20 of the person in charge of the work line 80, and the abnormal tendency level is the highest. In the case of a level (serious abnormal tendency), it is provided gradually as the abnormal tendency level becomes higher (as the degree of abnormal tendency increases), such as providing it to the terminal device of the administrator who manages the entire system. The provision level is expanded to increase the person in charge or to increase the position of the person in charge.

[5.7] Abnormal Cause Estimation Processing Unit [5.7.1] Overview of Abnormal Cause Estimation Processing Unit Next, details of the abnormal cause estimation processing unit 427 in the server device 40 of the present embodiment will be described.

The abnormality cause estimation processing unit 427
(1) A lot (specifically, a single or a plurality of work lines 80 in the same lot), a work line 80, a work process, or one of them set in advance as an object by the administrator terminal device 20 When the sanitary condition is determined to be abnormal or abnormal, or
(2) In the case where the specimen extracted from the target object is determined as abnormal by the medium determination in the film-type medium 60 for culturing the colony,
Information on the number of colonies is obtained from the medium information of the film-type medium 60 having the specimen extracted from the object or from the medium information of the film-type medium 60 that has become abnormal in the medium determination, and based on the acquired information on the number of colonies Thus, the cause of the abnormality is estimated from the work history information of the object and provided to the administrator.

Specifically, the abnormality cause estimation processing unit 427
(A) When it is determined by the first determination process or the second determination process executed in the sanitary condition analysis processing unit 426 that the sanitary condition of the object is abnormal.
(B) When the film-type medium 60 in the specimen extracted from the object is determined to be abnormal in the medium determination of the colony detection determination unit 423, or
(C) When it is determined that the work process, work line 80 or lot is abnormal in the process determination, line determination or lot determination of the lot determination processing unit 424,
A work element including the work event and work attribute of the target object is extracted from the work history information DB 406.

  Then, the abnormality cause estimation processing unit 427 includes the corresponding medium information (that is, each film-type medium 60 having a sample extracted from the object or abnormality) in each work element extracted from the object determined to be abnormal or abnormal. Based on the number of colonies included in the determined film-type medium 60 (the medium information registered by image analysis at each culture inspection time), a working element having a predetermined condition is identified as the cause of abnormality.

  On the other hand, when the abnormality cause estimation processing unit 427 identifies the work event or the work attribute as the abnormality cause, the abnormality cause estimation processing unit 427 provides the administrator terminal device 20 with information on the abnormality cause that is the identified work element (that is, abnormality cause estimation information). The information is provided to an administrator (or an appropriate administrator if there are a plurality of administrators) by a predetermined method.

[5.7.2] Abnormal cause estimation processing based on work event Next, an abnormal tendency cause estimation processing based on a work event executed in the abnormality cause estimation processing unit 427 of this embodiment will be described with reference to FIG. In addition, FIG. 9 is a figure for demonstrating the abnormal tendency cause estimation process based on the work event performed in the abnormality cause estimation process part 427 of this embodiment.

  The abnormality cause estimation processing unit 427 is a case where the sanitary state of the target object is determined to be abnormal, and retrieves the work history information of the target object in the work history information DB 406 and performs the work of the target object. When a work event is included in the element, work element content information stored in association with the work event is acquired from the work history information.

  Then, when a work event is included in the extracted work element, the abnormality cause estimation processing unit 427 determines, for each extracted work event, the timing at which the work event is executed or the timing at which the execution is scheduled and the colony of the target object. The operation event having a predetermined condition is identified as the cause of the abnormality by comparing with the timing when the fluctuation of the number occurs.

  In particular, the abnormality cause estimation processing unit 427 is information stored as work element content information in the work history information DB 406, and is a timing when a work event has already been executed from the work element content information (hereinafter referred to as “execution timing”). Or information indicating the timing of an unexecuted work event that has already passed (hereinafter referred to as “unexecuted timing”).

  In addition, the abnormality cause estimation processing unit 427 acquires information on the evaluation period used when it is determined that the abnormality tendency is present, that is, the start timing of the evaluation period.

  Then, the abnormality cause estimation processing unit 427 includes the timing of the start of the evaluation period used by the determination process executed in the sanitary condition analysis processing unit 426, the execution timing in each work event, the non-execution timing, or both timings, As a predetermined condition, a work event having a timing that coincides with the start timing of the evaluation period or a timing before the start timing and having the closest timing in a predetermined period (for example, within 3 hours) Is identified as the cause of the abnormality.

In addition, as a work event of this embodiment,
(1) Events based on work such as work start and work pause,
(2) Events based on the cleaning of objects and machine or line changes in some work processes,
(3) An event based on a worker who is engaged in work on an object such as a change of worker, and
(4) An event based on a product such as a change in the raw material of the product or a change in a supplier is included, and each of the events (1) to (4) includes an executed work event and an unexecuted work event.

  For example, in the case where the object is a work line A, when a work line pause, an unexecuted cleaning event, and an operator change event are acquired as work events, as shown in FIG. Since the executed cleaning event is before the start timing of the evaluation period and is closest to the start timing of other events, the abnormality cause estimation processing unit 427 identifies an unexecuted cleaning event as an abnormal cause.

  In addition, when comparing the start timing of the evaluation period and the timing of the work event, the abnormality cause estimation processing unit 427 has, as a predetermined condition, a timing that coincides with the start timing of the evaluation period or a timing before the start timing. The work event having the closest timing in the predetermined period is specified as the cause of the abnormality, but the timing before the start timing of the evaluation period is outside the predetermined period and the closest timing, or The work event having the closest timing after the start of the evaluation period may be specified as the cause of the abnormality, and the work event having the closest timing is given a high degree of reliability and ranked. May be.

  On the other hand, when it is determined that the film-type medium 60 in the sample extracted from the target set in advance by the medium determination of the colony detection determination unit 423 is abnormal, the abnormality cause estimation processing unit 427 determines the medium determination. When the culture inspection time of the film-type medium 60 that has been executed is compared with the execution timing, non-execution timing, or both timings in each work event, and the sanitary state of the object is determined to be abnormal Similarly, the work event having the timing that coincides with the culture examination time or the timing closest to the timing before the culture examination time is specified as the cause of the abnormality.

  In such a case, the abnormality cause estimation processing unit 427 performs an abnormal tendency cause estimation process when it is determined that the film-type medium 60 at two or more consecutive culture examination times is abnormal in the same object. May be executed. That is, if the abnormality determination is performed only once, it may be an error of the system or the like. Therefore, the prevention can be executed by executing such a process.

  In such a case, for example, the abnormality cause estimation processing unit 427 compares the culture inspection time of the film-type medium 60 that is initially determined to be abnormal with the non-execution timing or both timings. Identify the work event as the cause.

  On the other hand, when the abnormality cause estimation processing unit 427 determines that the object set in advance by the process determination, line determination, or lot determination in the lot determination processing unit 424 is abnormal, as in the medium determination. The culture examination time of the earliest film-type medium 60 used by the process judgment, line judgment or lot judgment is compared with the execution timing, non-execution timing or both timings in each work event, and the hygiene of the object As in the case where the state is determined to be abnormal, the work event having the timing that coincides with the culture inspection time of the earliest film-type medium 60 is identified as the cause of the abnormality.

  That is, in such a case, the abnormality cause estimation processing unit 427 performs the process determination, the line determination, or the lot determination by executing a plurality of medium determinations as described above. The timing of the work event is compared with the film type medium 60 that is the earliest in the culture examination time. However, the abnormality cause estimation processing unit 427 may compare the culture inspection time of the other film type medium 60.

[5.7.3] Abnormal Cause Estimation Processing in Work Attributes Next, the abnormal tendency cause estimation processing in work attributes executed in the abnormal cause estimation processing unit 427 of this embodiment will be described with reference to FIG. In addition, FIG. 10 is a figure for demonstrating the abnormal tendency cause estimation process in the work attribute performed in the abnormality cause estimation process part 427 of this embodiment.

  The abnormality cause estimation processing unit 427 is a case where the sanitary state of the target object is determined to be abnormal, and retrieves the work history information of the target object in the work history information DB 406 and performs the work of the target object. When the element includes a work attribute, the medium information DB 401, the line information DB 402, the lot information DB 403, and the work management DB 404 are searched, and the evaluation period or the evaluation period used by the determination process of the sanitary state analysis processing unit 426 And the number of colonies included in the culture medium information of the target object is acquired together with the corresponding work attribute.

  Then, the abnormality cause estimation processing unit 427 aggregates the number of colonies for each predetermined timing in the target object according to the type of the work attribute for each same category in the extracted work attributes, and each collected work attribute The work attribute which has a predetermined condition about the fluctuation | variation of the number of colonies is specified, and the specified work attribute (namely, work element) is specified as a cause of abnormality.

  In particular, the abnormality cause estimation processing unit 427 has the number of colonies and the number of colonies while calculating the average and variance from the data group of the number of colonies aggregated in each work attribute type for each work attribute type in the same category. A normal distribution is generated for each type of work attribute based on the number of film type culture media 60 (hereinafter referred to as “the number of culture media”). Then, the abnormality cause estimation processing unit 427 specifies the optimum normal distribution by comparing the T-test for calculating the difference between two normal distributions or comparing three or more normal distributions for each type of work attribute in the same category. Analysis of multiple causes (for example, Dunnett's method in which there is one control group and two or more treatment groups, and the paired comparison of the control group and the treatment group is tested with respect to the population mean), etc. While calculating the p-value indicating the reliability, for each work attribute type, a normal distribution having a difference from another normal distribution is extracted, and the work attribute having the extracted normal distribution is used as an abnormality cause in the corresponding category. Identify.

In addition, as a work attribute of this embodiment,
(1) Attributes related to the object such as the work line 80 or the type of work process such as the work process included in the work line 80 when the object is the work line 80;
(2) Attributes relating to time when culture tests such as day of the week, morning, afternoon or midnight, or specific time, etc. (3) Worker ID involved in the work, and
(4) The attribute about goods, such as change of the raw material of goods or a delivery destination, is included. The same category indicates, for example, work process, day of the week, worker ID, and raw material, and the type of work attribute indicates process A and process B in the work process, or raw material A and raw material B in the raw material.

  For example, as shown in FIG. 10A, the abnormality cause estimation processing unit 427 has a category of work attribute “Delivery” and types of work attributes “Seller A”, “Seller B”, and “Seller”. In the case of “C”, when data on each work attribute is obtained from each DB such as the culture medium information DB 401 for the number of colonies in the evaluation period, the average and variance are calculated from the data group of the number of colonies obtained for each type of work attribute. However, a normal distribution is generated as shown in FIG. Then, the abnormality cause estimation processing unit 427 performs analysis of variance and multiple comparison, and extracts the supplier A from the supplier A, the supplier B, and the supplier C, assuming that the normal distribution is different from other normal distributions. In the category of supplier, the type of work attribute of supplier A is specified as the cause of the abnormality.

  Note that the abnormality cause estimation processing unit 427 identifies each identified work attribute as an abnormality cause when each of the plurality of work attribute categories identifies a work attribute causing the abnormality. Then, the abnormality cause estimation processing unit 427, in each work attribute category, can not extract any normal distribution having a difference from another normal distribution for each work attribute type, any type in the work attribute. Not specified as the cause of abnormality.

  Further, the abnormality cause estimation processing unit 427 may rank the abnormality causes in descending order of the reliability of the abnormality cause using the p value indicating the reliability of the abnormality cause estimation.

  On the other hand, the abnormality cause estimation processing unit 427 determines that the film-type medium 60 in the specimen extracted from the target set in advance by the medium determination of the colony detection determination unit 423 is abnormal, the medium information DB 401 The line information DB 402, the lot information DB 403, and the work management DB 404 are searched, colonies that belong to a period from a medium test time at which an abnormality is determined to a predetermined period before are included in the medium information of the target object Get the number along with the corresponding work attributes.

  And the abnormal cause estimation process part 427 calculates the average and dispersion | distribution from the data group of the number of colonies acquired in the classification of work attribute for every same category similarly to the above, and the number of film type culture media 60, and a colony. Generate normal distributions based on numbers, calculate the reliability (p value) of abnormal cause estimation using T-test or multiple comparison, etc., and normals that have differences from normal distributions of other work attributes for each category Extract the distribution to identify the cause of the abnormality.

  Similarly to the above, the abnormality cause estimation processing unit 427 may rank the abnormality causes in descending order of the reliability of the abnormality cause using the p value indicating the reliability of the abnormality cause estimation.

  On the other hand, the abnormality cause estimation processing unit 427 determines whether an object such as a work process, a work line 80, or a lot is detected by the process determination, line determination, and lot determination (hereinafter also referred to as “lot determination”) of the lot determination processing unit 424. When it is determined to be abnormal, the medium information DB 401, the line information DB 402, the lot information DB 403, and the work management DB 404 are searched, and the medium included in the medium information of the earliest film-type medium 60 used for lot determination or the like The number of colonies that belong to a period (for example, 48 hours or one week) from the inspection time to a predetermined period before and that is included in the culture medium information of the target object is acquired together with the corresponding work attribute.

[6] Hygiene management system operation process [6.1] Medium information registration process (portable communication terminal device)
Next, operation | movement of the culture medium information registration process in the portable communication terminal device 10 of this embodiment is demonstrated using FIG. In addition, FIG. 11 is a flowchart which shows the registration processing operation | movement of the culture medium information in the portable communication terminal device 10 of this embodiment.

  In this operation, it is assumed that corresponding lot information and line information associated with the work instruction sheet 70 are already stored in the line information DB 402 and the lot information DB 403.

  Further, it is assumed that the medium ID 66 or the instruction ID 71a is attached to the film-type medium 60 and the work instruction sheet 70 by a two-dimensional barcode.

  Further, in this operation, the number of colonies in each film-type medium 60 is detected at the time of registration in the medium information database 400, and the portable communication terminal device 10 uses RGB for capturing a medium image. It is assumed that calibration for the gradation value or the luminance value is performed.

  First, in the portable communication terminal device 10, when the application control unit 120 detects an activation instruction for the culture medium registration application via the operation unit 170 (step S101), the application control unit 120 reads the culture medium registration application from the application storage unit 101 and activates it ( Step S102). At this time, the application control unit 120 performs initialization of the work memory and other necessary processes under the control of the mobile terminal management control unit 190.

  Next, the application control unit 120 displays an image for interlocking with the display control unit 161 to select whether the initial registration of the film-type medium 60 or the post-culture registration after a predetermined time has elapsed from the start of the culture. It is displayed on the unit 160 and waits for its input (step S103).

  Next, when detecting an input of a selection instruction from the operation unit 170 (step S104), the application control unit 120 determines whether initial registration or post-cultivation registration and sets the result in flag information (step S105).

  Next, the application control unit 120 causes the display unit 160 to display a screen that prompts the imaging of the film-type medium 60, and waits for imaging by the image data generation unit 110 in conjunction with the operation unit 170 (step S106). At this time, the application control unit 120 causes a predetermined image to be superimposed on the display unit 160 in order to align the medium image to be acquired.

  Next, when the application control unit 120 detects imaging by the image data generation unit 110 in conjunction with the image data generation unit 110, the display control unit 161, and the operation unit 170 (step S107), the image data generation unit 110 causes the medium ID 66 to be detected. At the same time, the imaged medium image data of the film type medium 60 is acquired and stored in the image data storage unit 102 while giving a predetermined image ID (step S108).

  Next, the application control unit 120 acquires the current time from the timer 180 as the imaging time of the medium image data, and stores it in the image data storage unit 102 as metadata in association with the medium image data (step S109).

  Next, the application control unit 120 analyzes the two-dimensional barcode formed in a predetermined area of the acquired imaged culture medium image data, acquires the culture medium ID 66, and stores the image data in association with the culture medium image data. The information is stored in the unit 102 (step S110).

  Next, the application control unit 120 causes the display unit 160 to display a screen for acquiring the instruction sheet image data together with the instruction sheet ID 71a and the process ID 71b in conjunction with the display control unit 161, and waits for acquisition of the instruction sheet image data. (Step S111).

  Next, when the application control unit 120 detects imaging by the image data generation unit 110 in cooperation with the image data generation unit 110, the display control unit 161, and the operation unit 170 (step S112), an instruction in which the work ID 71 is imaged. The book image data is acquired and stored in the image data storage unit 102 in association with the culture medium image data acquired in step S108 (step S113).

  In addition, when acquiring the process ID 71b as the work ID 71, or when acquiring the one process ID 71b from the plurality of process IDs 71b, the application control unit 120 operates in conjunction with the display control unit 161 and the operation unit 170, and the user The process ID 71b to be acquired is displayed, and the corresponding process ID 71b is acquired.

  Next, the application control unit 120 analyzes the two-dimensional barcode formed in the predetermined region of the captured instruction image data and the medium image data, acquires the work ID 71, and corresponds to the instruction image data In addition, the image data is stored in the image data storage unit 102 (step S114).

  Next, the application control unit 120 acquires the current time as the imaging time of the medium image data from the timer 180, and in conjunction with the display control unit 161 and the operation unit 170, the application control unit 120 acquires the acquired instruction image data, work ID 71, The medium image data, medium ID 66, and imaging time are confirmed (step S115).

  Note that the application control unit 120 may re-acquire the culture image data based on an instruction from the operator when the acquired medium information is confirmed by the operator. At this time, the application control unit 120 may be able to correct the medium image data by the operator in conjunction with the display control unit 161 and the operation unit 170.

  Next, based on the operator's instruction, the application control unit 120 uses the terminal ID and the work ID 71 as well as the acquired medium image data and its metadata, and flag information indicating whether initial registration or post-culture registration as medium information. Then, the data is transmitted to the server device 40 via the network communication unit 130 (step S116), and the registration process of the portable communication terminal device 10 is terminated.

  At this time, when transmitting the culture medium information, the network communication unit 130 executes login for accessing the server device 40 based on the terminal ID or the input ID and password, and the server device 40 is completed after the login is completed. Communication line is established and medium information is transmitted.

[6.2] Medium information registration processing (server device)
Next, the registration processing operation of the culture medium information in the server device 40 of this embodiment will be described using FIG. In addition, FIG. 12 is a flowchart which shows the registration processing operation | movement of the culture medium information in the server apparatus 40 of this embodiment.

  In addition, this operation | movement is a process performed in conjunction with the culture medium information registration process performed by the portable communication terminal device 10, and the server apparatus 40 uses the culture medium information transmitted from the portable communication terminal apparatus 10 as a culture medium. This is a process for registering in the information DB 401.

  First, in the server device 40, when the communication control unit 410 receives the culture medium information transmitted from the portable communication terminal device 10 (step S300), the registration processing unit 421 is based on the flag information included in the received culture medium information. Whether the registration is initial registration or post-culture registration is determined (step S301).

  At this time, if the registration processing unit 421 determines initial registration, the process proceeds to step S302. If the registration processing unit 421 determines that it is not initial registration, that is, if it is determined to be post-culture registration, step S304 is performed. Move on to processing.

  Next, when it is determined as initial registration, the registration processing unit 421 extracts and specifies the work ID 71 included in the culture medium information (step S302).

  Next, the registration processing unit 421 registers the culture medium information in the culture medium information DB 401 based on the identified work ID 71 (step S303), and ends this operation. Although the culture start time is stored in advance in the work management DB 404, the registration processing unit 421 registers the imaging time included in the received medium information as the culture start time in the work management DB 404 in the process of step S303. Also good.

  On the other hand, if the registration processing unit 421 determines that the registration is after culture, it extracts and specifies the work ID 71 included in the culture medium information (step S304), and registers the culture medium information based on the imaging time included in the culture medium information. The culture examination time to be specified is specified (step S305).

  At this time, the registration processing unit 421 may be registered by designating a culture examination time for registering the culture medium information in conjunction with the portable communication terminal device 10, or the imaging time included in the received culture medium information. The culture examination time may be registered as it is. In addition, the registration processing unit 421 manages the culture medium registration at the culture test time that has already been performed, and specifies the culture test time based on the timing at which the culture medium information is received and the culture test time that has already been used to register the culture medium information. May be. That is, the registration processing unit 421 may specify the culture examination time by rewriting the execution flag each time the medium information is registered and comparing the received imaging time with reference to the information of the flag.

  Next, the registration processing unit 421 causes the colony detection determination unit 423 to specify a profile for detecting colonies using the work information based on the acquired medium information and the specified work ID 71 (step S307).

  Next, the colony detection determination unit 423 performs image analysis on the received medium image data based on the specified profile, and extracts the feature amount (luminance value) of each pixel constituting the medium image ( In step S308), the number of colonies generated in the specimen imaged based on the feature amount of each pixel constituting the culture medium image is detected and the number thereof is detected (step S309).

  Next, the colony detection determination unit 423 determines whether the detected number of colonies satisfies a predetermined condition based on the identified profile (step S310). That is, the colony detection determination unit 423 determines that it is acceptable (normal) when the predetermined condition is satisfied, and determines that it is unacceptable (abnormal) when the predetermined condition is not satisfied. In addition, the colony detection determination unit 423 is a sample extracted from an object such as a preset work line 80 when it is determined that the film-type medium 60 is unacceptable (that is, when it is determined as an abnormality determination). In the case of pass / fail judgment for the film-type culture medium 60 having the above, the abnormality cause estimation processing unit 427 is instructed to start the abnormality cause estimation process.

  The colony detection determination unit 423 is linked to the portable communication terminal device 10 to display the detected number of colonies and the result of the pass / fail determination on the display unit 160 of the portable communication terminal device 10 to allow the user to browse and confirm. You may do it. Details of the abnormality cause estimation processing of the abnormality cause estimation processing unit 427 will be described later.

  Next, the registration processing unit 421 specifies the culture start time information using the culture image data, the recognized medium ID 66, the determined pass / fail, the detected colony number, and the imaging time included in the medium information as the culture start time. The ID 71 is associated and registered in the culture medium information DB 401 (step S311), and this operation ends.

  The registration processing unit 421 displays line information and information to be registered on the display unit 160 of the portable communication terminal device 10, and based on a user instruction input via the portable communication terminal device 10, the culture medium Information or the like may be registered.

  Further, when the culture medium image data is transmitted from the portable communication terminal apparatus 10 and the medium ID 66 is recognized by analyzing each image data by the server apparatus 40, the registration processing unit 421 receives the reception in the process of step S201. The medium ID 66 imaged on each predetermined area of the medium image data thus obtained is analyzed, and the medium ID 66 is recognized and acquired. Similarly, the server device 40 also recognizes the work ID 71 in the instruction image data.

  Furthermore, although the above-mentioned operation is executed when the culture medium information is acquired by the portable communication terminal apparatus 10, the culture medium information acquired by the portable communication terminal apparatus 10 is recorded in the culture medium information DB 401 and then executed. May be.

[6.3] Lot Determination Processing Next, the operation of the lot determination processing in the server device 40 of this embodiment will be described using FIG. FIG. 13 is a flowchart showing the operation of lot determination processing in the server device 40 of this embodiment.

  In this operation, it is assumed that the corresponding medium information is registered, and process determination reference information, line determination reference information, and lot determination reference information are registered in advance.

First, when the communication control unit 410 of the server device 40 receives a lot determination instruction transmitted from the administrator terminal device 20 (step S351), the lot determination processing unit 424 can perform lot determination in conjunction with the communication control unit 410. A lot ID that can be determined by searching for a lot ID and the corresponding lot information are transmitted to the administrator terminal device 20 so that the administrator can view and select the lot ID, and an instruction for the lot ID to execute the lot determination process is sent. Wait (step S352).
The administrator terminal device 20 displays a lot ID that can be determined on a predetermined display screen so that the administrator can view and select the lot ID.

  Next, when the communication control unit 410 receives the lot ID specified by the administrator via the administrator terminal device 20 (step S353), the lot determination processing unit 424 determines the process of the process belonging to the corresponding lot, Each criterion information indicating the conditions for line determination and lot determination is read from the RAM / ROM 440 (step S354).

  Next, the lot determination processing unit 424 reads out various lot information, line information, and medium information of the corresponding lot ID (step S355), and performs process determination and line determination based on the read lot information, line information, and medium information. The lot determination is performed (step S356). Specifically, the lot determination processing unit 424 executes the process determination of each process specified by the lot information, and the line of each work line 80 specified by the lot information based on the process determination result of the process determination. Make a decision. Then, the lot determination processing unit 424 executes lot determination based on the line determination result.

  Next, in the process determination, line determination, and lot determination, the lot determination processing unit 424 determines that the work process, work line, or lot set in advance as an object is abnormal, the abnormality cause estimation processing unit 427. Is instructed to start the abnormality cause estimation process (step S357).

  The colony detection determination unit 423 is linked to the portable communication terminal device 10 to display the detected number of colonies and the result of the pass / fail determination on the display unit 160 of the portable communication terminal device 10 to allow the user to browse and confirm. You may do it. Details of the abnormality cause estimation processing of the abnormality cause estimation processing unit 427 will be described later.

  Next, the lot determination processing unit 424 allocates the lot determination result to the template while reading the predetermined template information in the determination report format, and generates report data (step S358).

  Finally, the lot determination processing unit 424 provides report data generated in conjunction with the communication control unit 410 to the corresponding administrator terminal device 20 (step S359), and ends this operation.

  When the administrator terminal device 20 receives the report data, the administrator terminal device 20 displays the report data so that the administrator can view it. However, the lot determination processing unit 424 may transmit the print data as print data that can be printed on the printer without transmitting the report data to the manager terminal device 20.

[6.4] Hygiene condition analysis providing process Next, the operation of the hygiene condition analysis providing process in the server device 40 of the present embodiment will be described with reference to FIG. In addition, FIG. 14 is a flowchart which shows operation | movement of the hygiene state analysis provision process in the server apparatus 40 of this embodiment.

  In this operation, it is assumed that an object for analyzing the hygiene state such as the work line 80 or a part thereof relating to a predetermined work process is set in advance, and an instruction from the administrator terminal device 20 or a predetermined timing (work element) This operation is executed every 12 hours. That is, the evaluation period is 12 hours immediately before the execution of this operation.

  In this operation, the culture medium information DB 401 stores a plurality of pieces of culture medium information on the object whose sanitary condition is to be analyzed. After a predetermined culture time has elapsed in the new film-type culture medium 60 every hour ( It is assumed that medium information after 48 hours has been registered.

  Furthermore, in this operation, it is assumed that the trend information that has been executed and registered before the set work element has already been registered in the trend information DB 405.

  First, when the sanitary condition analysis processing unit 426 detects an instruction from the administrator terminal device 20 or a predetermined timing (step S401), the corresponding medium information (that is, medium information during the evaluation period) is specified. Meanwhile, the number of colonies is acquired from the specified medium information (step S402). Specifically, the hygiene condition analysis processing unit 426 has the line ID of the work line 80 that is the object of the hygiene condition analysis process, and is medium information that has not yet been used for the hygiene condition analysis providing process, Each medium information is acquired by reading from the medium information DB 401 up to the latest registered medium information.

  Next, the sanitary state analysis processing unit 426 generates a change graph indicating the time-series change of the number of colonies by arranging the acquired values of the number of colonies in time-series (step S403).

  Next, the sanitary condition analysis processing unit 426 performs determination processing (specifically, first determination processing or second determination processing) in the evaluation period based on the generated change graph (step S404), and during the evaluation period It is determined whether or not the sanitary state of the object (for example, the work line 80) shows an abnormal tendency (step S405).

  Specifically, the hygiene condition analysis processing unit 426 generates a differential graph from the change graph based on a predetermined unit time as the first determination process in the process of step S404, and performs the differentiation within the evaluation period. A determination process for determining whether or not the value of the graph exceeds the upper limit threshold value is executed.

  In addition, the sanitary condition analysis processing unit 426 has a plurality of pieces of medium information in a predetermined period before the evaluation period (that is, the line ID of the work line 80 that is the object of the sanitary condition analysis process) as the second determination process. The upper limit based on the number of samples and a predetermined confidence interval centered on the average number of colonies while calculating the average value and the variance value from the number of colonies in each medium information) in the corresponding period A threshold value and a lower limit threshold value are respectively determined, and a determination process for determining whether or not the number of colonies in the evaluation period of the change graph exceeds the upper limit threshold value is executed.

  Furthermore, in the process of step S405, the sanitary condition analysis processing unit 426 determines that the sanitary condition of the object (for example, the work line 80) shows an abnormal tendency, that is, the number of colonies during the evaluation period or When it is determined that the change in the number of colonies indicates an abnormal tendency, the process proceeds to step S411, and when it is determined that no abnormal tendency is indicated, the process proceeds to step S421.

  In addition, in the process of step S405, the sanitary state analysis processing unit 426 determines whether all the number of colonies or changes in the number of colonies during the evaluation period exceed the upper threshold, and the number of all colonies or the number of colonies. If the change in the number exceeds the upper threshold, the number of colonies during the evaluation period or the change in the number of colonies indicates an abnormal tendency, and the process proceeds to step S411.

  Next, when it is determined that the number of colonies during the evaluation period or the change in the number of colonies indicates an abnormal tendency, the sanitary state analysis processing unit 426 turns on a flag indicating the determination of the abnormal tendency and indicates the abnormal tendency. Trend information is generated (step S411).

  Specifically, the hygiene state analysis processing unit 426 generates the trend information of the evaluation period together with the read trend information while reading the past trend information associated with the same work element from the culture medium information DB 401. The sanitary state analysis processing unit 426 maintains the state when the flag indicating the determination of the abnormal tendency is already on.

  Next, the hygiene state analysis processing unit 426 transmits the fact information to the administrator terminal device 20 while registering the generated trend information in association with the corresponding work element in the culture medium information DB 401 (step S412).

  Next, the hygiene condition analysis processing unit 426 instructs the abnormality cause estimation processing unit 427 to start the abnormality cause estimation processing (step S413) and ends the operation. Details of the abnormality cause estimation processing of the abnormality cause estimation processing unit 427 will be described later.

  On the other hand, when it is determined that the number of colonies during the evaluation period or the change in the number of colonies does not indicate an abnormal tendency, the sanitary state analysis processing unit 426 determines whether the flag indicating the abnormal tendency determination is on ( In step S421), if the flag is on, the process proceeds to step S422. If the flag is not on (that is, off), the operation is terminated.

  Next, when the sanitary state analysis processing unit 426 determines that the flag indicating the abnormal tendency determination is ON, it determines whether or not the number of colonies during the evaluation period falls below the lower limit threshold (step S422). When it is determined that the number of colonies is lower than the lower limit threshold, the process proceeds to step S423, and when it is determined that the number of colonies is not lower than the lower limit threshold, this operation is terminated.

  Next, when the sanitary state analysis processing unit 426 determines that the number of colonies during the evaluation period is below the lower limit threshold, the hygiene state analysis processing unit 426 turns off the flag indicating the determination of an abnormal trend and generates trend information indicating an improvement trend. (Step S423).

  Specifically, the hygiene state analysis processing unit 426 generates the trend information of the evaluation period together with the read trend information while reading the past trend information associated with the same work element from the culture medium information DB 401.

  Next, the hygiene condition analysis processing unit 426 transmits the fact information to the manager terminal device 20 while registering the generated trend information in association with the corresponding work element of the culture medium information DB 401 (step S424), and this operation End.

[6.4] Abnormal Cause Estimating Process Next, the operation of the abnormal cause estimating process in the server device 40 of the present embodiment will be described with reference to FIG. FIG. 15 is a flowchart showing the operation of the abnormality cause estimation process in the server device 40 of this embodiment.

  In this operation, the start of the abnormality cause estimation process is instructed by the process in step S310 of the culture medium registration process in FIG. 12, the step S357 of the lot determination process in FIG. 13, or the process of step S413 in the sanitary state analysis process in FIG. It will be executed if it is done. However, this operation is not limited to the start instruction described above, and may be executed based on an administrator instruction.

  First, when the abnormality cause estimation processing unit 427 detects an instruction to start the abnormality cause estimation process as described above (step S501), the abnormality cause estimation processing unit 427 extracts a work element including the work event and work attribute of the target object from the work history information DB 406. (Step S502).

  At this time, the abnormality cause estimation processing unit 427 acquires work element content information stored in association with the work event or work attribute in the work element extracted from the work history information.

  Next, the abnormality cause estimation processing unit 427 determines whether or not a work event is included in the extracted work element (step S503), and when it is determined that a work event is included in the work element In step S511, the process proceeds to step S511. If it is determined that the work event is not included, the process proceeds to step S520.

  Next, when it is determined that the work event is included in the extracted work element, the abnormality cause estimation processing unit 427 schedules or executes the work event for each extracted work event. The timing (hereinafter referred to as “event timing”) is compared with the timing (hereinafter referred to as “variation timing”) when the change in the number of colonies of the target object occurs (step S511). For example, the abnormality cause estimation processing unit 427 includes the start timing of the evaluation period used by the determination process executed in the sanitary state analysis processing unit 426, the execution timing in each work event, the non-execution timing, or both timings, Compare

  Then, the abnormality cause estimation processing unit 427 identifies a work event having a timing that matches the start timing of the evaluation period and a predetermined condition as an abnormality cause (step S512), and proceeds to the process of step S520. For example, the abnormality cause estimation processing unit 427 identifies a work event having a timing that coincides with the start timing of the evaluation period or a timing closest to the start timing as an abnormality cause.

  Subsequently, when the abnormality cause estimation processing unit 427 determines that the work event is not included in the work element acquired in the process of step S503, or the process obtained in step S520 is continued, the acquired work is performed. It is determined whether a work attribute is included in the element (step S520). At this time, if the abnormality cause estimation processing unit 427 determines that the work attribute is included in the acquired work element, the process proceeds to step S521, and the work attribute is not included in the acquired work element. If it is determined, the process proceeds to step S515.

  Next, the abnormality cause estimation processing unit 427 corresponds to the number of colonies included in the culture medium information already acquired in the culture medium information registration process or other processes, or the database 400 when the work attribute is included in the work element. The number of colonies included in the culture medium information is acquired (step S521).

  Specifically, when acquiring from the database 400, the abnormality cause estimation processing unit 427 searches the culture medium information DB 401, the line information DB 402, the lot information DB 403, and the work management DB 404, and the determination process of the sanitary state analysis processing unit 426 is performed. The number of colonies that belong to the evaluation period used by or a predetermined period including the evaluation period (for example, the period from the implementation date of the treatment to one week before) and included in the culture medium information of the target , Along with the corresponding work attributes. Moreover, the abnormality cause estimation processing unit 427 acquires the number of colonies included in the corresponding culture medium information from the culture medium information belonging to the evaluation period acquired by the hygiene condition analysis process.

  Next, the abnormality cause estimation processing unit 427 aggregates the number of colonies for each predetermined timing in the target object according to the type of the extracted work attribute for each category of the work attribute, and colonies of the collected work elements. A work attribute having a predetermined condition with respect to the variation in the number is specified, and the specified work attribute is specified as a cause of abnormality (step S522).

  For example, the abnormality cause estimation processing unit 427 calculates the average and the variance from the data group of the number of colonies acquired according to the type of the work attribute for each category of the work attribute, and calculates the number of colonies and the number of the film-type medium 60 ( Hereinafter, a normal distribution is generated for each type of work attribute based on “the number of mediums”), and a T test for calculating a difference between two normal distributions or comparing three or more normal distributions to obtain an optimal distribution. A p-value indicating the reliability of abnormality cause estimation is calculated using analysis of variance and multiple comparison for specifying a normal distribution. Then, the abnormality cause estimation processing unit 427 extracts a normal distribution having a difference from other normal distributions from the normal distribution for each type of work attribute, and sets the work type having the extracted normal distribution in the corresponding work attribute. Identify the cause of the abnormality.

  Next, the abnormality cause estimation processing unit 427 generates cause estimation information that can be displayed on the administrator terminal device 20 by using the work attribute and the work event as both of the specified abnormality cause (step S531).

[7.6] Modification 6
In the above-described embodiment, the sanitary state analysis processing unit 426 of the present embodiment, as the first determination process, differentiates the change in the number of colonies during the evaluation period by differentiating the change graph based on a predetermined unit period. Periods that have the same length as the current evaluation period, such as the current evaluation period (hereinafter referred to as the “current evaluation period”) and the previous evaluation period (hereinafter referred to as the “previous evaluation period”). Each integration in the change graph may be executed, and when the difference is positive and equal to or greater than a predetermined threshold value, it may be determined that the tendency is abnormal.

  Specifically, the hygiene condition analysis processing unit 426 changes based on the number of colonies of each work line acquired at every predetermined timing (1 hour) during the evaluation period in the same manner as described above. A graph f (t) is generated.

  Further, as shown in FIGS. 12A and 12B, the sanitary condition analysis processing unit 426 is obtained by integrating the generated change graph f (t) of the work line A and the work line B in the evaluation period. When the integrated value for the previous evaluation period and the integrated value for the current evaluation period are compared and the difference is positive and greater than a predetermined threshold It is determined that the tendency is abnormal.

  For example, when the integrated value a (current) of the work line A in the evaluation period is “120” and the integrated value b (current) of the work line B is “55”, the work line A of the previous evaluation period When the integral value a (front) is “60” and the integral value b (front) of the work line B is “50”, the difference for the work line A is “+60” and the difference for the work line B is If “+5” is set and these values are equal to or greater than a predetermined threshold, the sanitary condition analysis processing unit 426 determines that the tendency is abnormal.

  Further, the sanitary condition analysis processing unit 426 is a case where the difference between the integrated values of the current evaluation period and the previous evaluation period is negative and equal to or less than a predetermined threshold value within a certain period after the determination of the abnormal tendency. The integrated value in the change graph in the evaluation period at this time is compared with the integrated value in the current evaluation period, and when the difference is negative and is equal to or greater than a predetermined threshold, it is determined that the trend is improving.

[7.7] Modification 7
In the second determination process, the sanitary state analysis processing unit 426 of the present embodiment acquires the number of colonies of the plurality of medium information before the evaluation period, and based on the number of colonies, the upper limit value or the lower limit value of the number of colonies However, it may be set manually by an operator or an administrator.

  In this case, the administrator terminal device 20 sets an upper limit value or a lower limit value according to processing of a predetermined application based on the operation of the operator or the administrator.

[7.8] Modification 8
In the present embodiment, apart from the medium determination, the process determination, and the line determination (hereinafter collectively referred to as “medium determination and the like”), the abnormality tendency of the object based on the determination processing result in the sanitary state analysis processing unit 426. Or although the improvement tendency after abnormal tendency determination is determined, you may determine the abnormal tendency of a target object or the improvement tendency after abnormal tendency determination using culture medium determination etc.

  That is, in this embodiment, the sanitary condition analysis processing unit 426 determines whether or not each film type medium 60 during the evaluation period is abnormal based on a predetermined condition and the number of colonies of each film type medium 60 ( The above-mentioned medium determination) is executed, and it is determined whether or not the determination result of whether or not each of the determined film-type mediums 60 is abnormal includes a determination condition. You may determine an improvement tendency.

  Specifically, if the process to be determined in the above process determination is not “abnormal”, the work line 80 to be determined in the above line determination is not “abnormal”, or the determination target in the above lot determination. Is a lot that is not “abnormal”, and is a part of a determination target of medium determination, process determination, or line determination used for determination processing of an object having an abnormal tendency and an improvement tendency (for example, a part of the film-type medium 60) Or a part of the work line 80) is determined as “abnormal”, it is determined that there is an abnormal tendency with respect to the object, and the medium determination, the process determination, or the line determination is determined in the subsequent evaluation period. When a part of the object is determined to be “normal”, it may be determined that the object has an improvement tendency.

For example, when the object is the work line 80, the sanitary condition analysis processing unit 426
(1) It is a case where the line determination of the work line 80 which is an object during the evaluation period is determined to be “normal”, and
(2) The medium determination of the plurality of film type culture media 60 based on the specimen extracted from the work line 80 during the evaluation period is 1 or the medium determination of the plurality of film type culture media 60 determined as “abnormal” If
It is determined that the object has an abnormal tendency, and in the medium determination of the plurality of film-type mediums 60 in the subsequent evaluation period, the medium determination of one or a plurality of film-type mediums 60 determined as “normal” is determined. When it is done, it will be determined that there is a tendency to improve the object.

  In this case, in the medium determination or the like, a machine learning method such as SVM (Support Vector Machine), neural network, or Bayesian estimation is used instead of the above-described determination methods of medium determination, process determination, or line determination. The presence or absence of abnormality in the medium determination or the like may be determined.

That is, the sanitary condition analysis processing unit 426 executes the calculation by SVM, neural network or Bayesian estimation (calculation by the binary classification method), so that the result of the medium determination or the like already determined in the past or the medium determination or the like can be obtained. Based on multiple samples already run,
(A) Identification conditions based on the number of colonies of each film-type medium 60 determined to be abnormal and normal in the lot determination processing unit 424, or
(B) In the lot determination processing unit 424, an identification condition such as the average value or the total number of the colonies when the process determination or line determination is performed as abnormal and normal,
The determination is made, and the abnormal tendency and the subsequent improvement tendency of the object in the evaluation period are determined according to the determined identification condition.

  For example, in the case of the medium determination, the sanitary state analysis processing unit 426 displays each determination result of abnormality or normal labeled in the film-type medium 60 that has already been determined in the past, or abnormality or normal that has been previously labeled. Samples of the number of colonies of the film-type medium 60 determined for the medium are classified into two classes, an identification plane (identification condition) for identifying the class is set as a determination condition, and based on the set determination condition, You may perform the medium determination which determines the presence or absence of abnormality of each film type culture medium 60 during an evaluation period.

[7.9] Modification 9
The abnormality cause estimation processing unit 427 of the present embodiment determines that the sanitary state of the object is abnormal or has an abnormal tendency, and each work event is not a cause of abnormality and any of the categories of each work attribute. Therefore, when one or more work events or work attributes having a predetermined condition cannot be extracted, none of the work elements in the work attributes are specified as the cause of abnormality, but two or more work attributes Analyzing the size of interaction (combination of superiority or inferiority of any work attribute depending on the level of other work attributes), and combining two or more work attributes that belong to multiple work attribute categories. You may specify as a cause of abnormality.

  For example, the abnormality cause estimation processing unit 427 identifies the combination of the work attribute “Seller A” in the work attribute category “Supplier” and the work attribute “Raw material 1” in the “Raw material” category as the cause of abnormality. A combination of work attributes in a plurality of categories may be specified as the cause of abnormality.

  Specifically, the abnormality cause estimation processing unit 427 is configured so that any of the changes in the number of colonies in each work attribute aggregated for each work attribute category does not satisfy a predetermined condition (that is, in any category). In the combination of work attributes belonging to a plurality of categories (for example, two or three categories), when a work attribute having a normal distribution having a difference from the normal distribution of other work attributes cannot be extracted) Any of the numerical fluctuations performs a statistical hypothesis test such as a null hypothesis or an alternative hypothesis that “does not have a predetermined condition” or “has the predetermined condition”.

  Then, based on the statistical hypothesis test result, the abnormality cause estimation processing unit 427 calculates a combination of a plurality of work attributes for each combination of the work attributes in a plurality of categories. It is determined whether or not a predetermined condition for the variation in the number of colonies is satisfied, and a combination of one work attribute having the predetermined condition is specified as the cause of the abnormality.

For example, when using the null hypothesis, the abnormality cause estimation processing unit 427 calculates the average, variance, and standard deviation of each work attribute combination for each work attribute combination in a plurality of categories. Based on each value
(1) Sum of squares of combinations of each work attribute (dispersion x number of data of each work attribute),
(2) Total sum of squares (total variance x number of all data),
(3) Sum of squares within the county (total sum of squares of all work attribute combinations),
(4) Sum of squares between groups (total sum of squares-sum of squares within county),
(5) Degree of freedom within the county (total number of data for each work attribute combination minus 1),
(6) Degree of freedom between groups (number of combinations of work attributes-1),
(7) Overall degree of freedom ((total number of data in all work attribute combinations-1)),
(8) Square average within the county (sum of squares between groups / degree of freedom between groups), and
(9) F value (group average / group average)
Is calculated, and it is determined whether or not the F value belongs to the rejection area with reference to the F distribution table (5% significance level).

  Then, when the F value belongs to the rejection area, the abnormality cause estimation processing unit 427 generates a normal distribution using the mean and variance for each combination of work attributes, assuming that the null hypothesis is denied. In addition, as described above, the difference between the two normal distributions is calculated by using a T-test for calculating the difference between the two normal distributions, or comparing three or more normal distributions and specifying the optimum normal distribution, and multiple comparison. Is extracted, and a combination of work attributes having the extracted normal distribution is identified as the cause of abnormality.

  As described above, in the sanitary management system S of the present embodiment, if information on colonies such as the number of colonies during the evaluation period acquired based on the film-type medium 60 or changes thereof is acquired, a work line for manufacturing or inspecting products. It is possible to provide the administrator with trend information such as an abnormal tendency indicating an abnormality in the hygiene status of an object such as 80 or a part thereof, or an improvement tendency indicating that the abnormal tendency has been improved. It is possible to monitor an abnormal tendency indicating an abnormality in the sanitary condition or a subsequent improvement tendency while reducing the burden on the person.

  Therefore, in the sanitary management system S of the present embodiment, it is confirmed that the sanitary condition is prevented from worsening with a simple configuration, and the improvement of the deteriorated sanitary condition is confirmed without performing complicated operations by the administrator. In addition, it is possible to grasp the trend of the sanitary condition of the object for each work element such as date and time, lot (that is, product lot), worker, and weather.

  Moreover, in the sanitary management system S of this embodiment, since the process at the time of providing the trend information in the sanitary state of the object can be digitized, the medium is wasted by using the imaged medium image. In addition to being able to conserve resources without consuming it, it is also possible to conserve resources without wasting paper or other real media by digitizing the provision of trend information. Can be planned.

  In the sanitary management system S of the present embodiment, the description has been made using food. However, the present invention is not limited to the food, and can be applied to products that are provided to all living organisms including drugs and drugs. .
