Description

[Technical Field]

[0001] The present invention relates to an information processing device or the like that processes information related to risk prediction activities. [Background technology]

[0002] At work sites such as factories and construction sites, risk prediction activities are conducted to predict risks associated with the work in order to ensure safe work. Various improvements have been made to enhance the effectiveness of such risk prediction activities. For example, Patent Document 1 describes a method of storing quizzes related to safety and health for each work process and outputting the quiz based on the work process performed by the worker. Patent Document 2 also describes a method of displaying on a screen both important and inappropriate precautions corresponding to the input work content, and having participants select and input the correct important precautions in the form of a quiz.

[0003] [Patent Document 1] Patent Publication No. 2021-93067 [Patent Document 2] Patent No. 6510701 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Documents 1 and 2 simply describe outputting and displaying quizzes, but do not disclose the specific format of the quizzes to be created. For example, if a fixed quiz is simply output, workers will memorize the quizzes by repeatedly answering the same pre-prepared quizzes about the same work. This reduces the effectiveness of the quizzes in enabling workers to think about hazard prediction.

[0005] One aspect of the present invention aims to create questions related to risk prediction activities that are tailored to the nature of the work. [Means for solving the problem]

[0006] In order to solve the above problem, an information processing device according to one embodiment of the present invention comprises: a registration unit that stores in a memory unit registered information that corresponds a dangerous event wording, which is a wording that represents a dangerous event input as a danger prediction item related to work content; a situation wording, which is a wording that represents a situation in which the dangerous event occurs input as the danger prediction item; and a specified result specified from a group of pre-prepared results; and a question creation unit that reads out the selected registered information from the memory unit and creates a correct answer question based on the read registered information, in which the correct answer wording expresses in a sentence that if the dangerous event occurs in the situation, it will bring about the specified result. [Effects of the Invention]

[0007] According to one aspect of the present invention, questions regarding risk prediction activities can be created according to the work content. [Brief explanation of the drawings]

[0009] [Embodiment] Hereinafter, one embodiment of the present invention will be described in detail.

[0010] <Outline of the information management system> 1 is a block diagram showing a schematic configuration of an information management system 101 according to the present embodiment.

[0011] As shown in Fig. 1, the information management system 101 includes a management terminal 1 (input terminal), a cloud server 2 (information processing device), a work registration terminal 3 (operation terminal) provided for each of facilities F1 to Fn (n is a natural number), and multiple terminal devices 4. The cloud server 2 communicates with the management terminal 1, the work registration terminals 3 provided for each of the facilities F1 to Fn, and the terminal devices 4 used by workers at each of the facilities F1 to Fn via the Internet 100. In the following description, the facilities F1 to Fn will be referred to as facility Fi or facility F unless otherwise specified.

[0012] The information management system 101 manages various types of information related to work so that the work in facilities F1 to Fn can be carried out smoothly. Furthermore, as part of hazard prediction activities, the information management system 101 creates questions based on hazard prediction items related to the work and provides the questions along with the correct answers to the terminal devices 4 carried by the workers. The workers answer the provided questions by operating the terminal devices 4 carried by them, and are notified by the terminal devices 4 whether their answers are correct or incorrect. This allows the workers to recognize the hazard prediction items related to the work before starting the work.

[0013] The questions are created based on registration information that associates wording related to risk prediction items with designated results selected from the results constituting the result group prepared in advance as master data in the cloud server 2. The registration information is registered in the cloud server 2 by operating the work registration terminal 3 in the facilities F1 to Fn. The result group is a collection of wording that expresses the expected results of accidents and the like for various tasks performed in the facilities F1 to Fn. Examples of results that are prepared include falling, toppling, collision, falling, collapse, getting caught in, high / low temperature, electric shock, and fire. The master data is registered from the management terminal 1.

[0014] The management terminal 1 manages the cloud server 2. Specifically, it views various types of information stored in the storage unit 22 of the cloud server 2 and edits the master data in the storage unit 22. In addition, an administrator who has the authority to operate the management terminal 1 can use the management terminal 1 to register new facilities in the cloud server 2. The administrator is responsible for the overall management of the information management system 101.

[0015] The cloud server 2 creates and registers registration information for each facility F1 to Fn based on the master data registered by the management terminal 1 and the wording related to the hazard prediction items input by the work registration terminal 3, and manages the registered registration information. The cloud server 2 creates questions based on the hazard prediction items related to the above-mentioned work based on the registration information through operations on the work registration terminal 3. The cloud server 2 manages detailed information about the history of work performed in the past and work scheduled for the future. The cloud server 2 also manages information used to create questions in the memory unit 22. This information will be explained in detail later.

[0016] The work registration terminal 3 communicates with the cloud server 2 and functions as an operation terminal that accepts input operations for creating questions in the cloud server 2.

[0017] The terminal device 4 is a portable device such as a smartphone carried by a worker performing work at each of the facilities F1 to Fn. The terminal device 4 receives questions and transmits answers by communicating with the cloud server 2, receives confirmation information from the cloud server 2, and transmits work results to the cloud server 2. The confirmation information is various types of information that the worker must confirm in order to perform the work. The confirmation information will be explained in detail later.

[0018] Cloud Server Configuration The cloud server 2 will now be described in detail.

[0019] Fig. 2 is a block diagram showing a detailed configuration of the information management system 101. Fig. 3 is a diagram showing the relationship between the registration information registered by the registration management unit 212 of the cloud server 2 and the work information.

[0020] As shown in FIG. 2, the cloud server 2 includes a control unit 21, a memory unit 22 (storage unit), and a communication unit 23 (transmission unit, reception unit).

[0021] The control unit 21 includes a master data management unit 211, a registration management unit 212 (registration unit), a question creation unit 213, a question management unit 214, and a work information management unit 215.

[0022] The master data management unit 211 manages the master data stored in the storage unit 22. The master data management unit 211 registers, views, and edits the master data in response to the administrator's operation of the input unit 13 (described later) of the management terminal 1. The master data management unit 211 also registers a new facility F in response to the administrator's input operation of the management terminal 1.

[0023] The registration management unit 212 manages the registration of registration information in the storage unit 22. The registration management unit 212 stores the registration information in the storage unit 22 in response to an input operation on the work registration terminal 3 by a person in charge of facility F who has the authority to register the registration information (hereinafter referred to as the "facility person in charge"), and performs registration.

[0024] As shown in FIG. 3, the registration management unit 212 creates basic registration information, which serves as the basis for the registration information, by associating a dangerous event description, a situation description, and a specified result. The basic registration information does not include a countermeasure description, which will be described later, but functions as registration information. The dangerous event description is a description representing a dangerous event that is input to the cloud server 2 by the facility staff member operating the input unit 33 of the work registration terminal 3 as a danger prediction item related to the work content. The situation description is a description input to the cloud server 2 by the facility staff member operating the input unit 33 as a danger prediction item, and represents the situation in which the dangerous event will occur. The specified result is a result specified by the facility staff member operating the input unit 33 from a group of results prepared in advance as master data in the cloud server 2. The work content is like a work name that succinctly describes the work content, and is expressed as, for example, furnace cleaning or equipment inspection.

[0025] The registration management unit 212 creates registration information by associating countermeasure statements with the dangerous event statements, situation statements, and designation results that constitute the basic registration information. The countermeasure statements are statements that are input to the cloud server 2 by the facility staff member operating the input unit 33, and represent countermeasures to avoid the dangerous event. In the registration information, one countermeasure statement is often associated with the basic registration information described above, but multiple different countermeasure statements may also be associated with the basic registration information.

[0026] The registration management unit 212 stores the task information and the above-mentioned registration information in the storage unit 22. The task information is information in which predetermined related information relating to various tasks is associated with the task content. The registration management unit 212 stores the task information and the registration information in the storage unit 22 in a state in which the related information and the registration information are associated with each other. As shown in FIG. 3, multiple pieces of related information may be associated with one task content. Furthermore, although not shown, as will be described later, the registration information may also be associated with the purpose of the question. This allows the question creation unit 213 to create questions that match the purpose of the question when creating questions using the registration information.

[0027] The related information is stored as master data in the storage unit 22 and managed by the cloud server 2. The related information includes the type of work and events that affect the work. Examples of the type of work include specific work such as welding, working at heights, cleaning work, and installation work, as well as work involving the use of fire and hazardous materials such as work involving the use of hazardous substances. Examples of events that affect the work include weather effects (outdoors) and health abnormalities.

[0028] The registration management unit 212 associates the purpose of setting a question with a predetermined number of pieces of registered information for each purpose and stores them in the storage unit 22. Examples of purpose of setting a question include prior confirmation of hazard prediction items for work and education. Examples of the former purpose of setting a question include prior confirmation of hazard prediction items for work that has been planned in advance (normal work) and prior confirmation of hazard prediction items for work that requires an emergency response (emergency work). Examples of the latter purpose of setting a question include being part of a training activity that is unrelated to the work and is carried out to improve a worker's ability to predict hazards.

[0029] When new registration information is registered from a work registration terminal 3 at one facility F, the registration management unit 212 stores the registration information in the registration information database of the memory unit 22 so that it can be newly registered as registration information at another facility F.

[0030] The question creation unit 213 reads registration information from the storage unit 22 in response to the facility staff member operating the input unit 33 of the work registration terminal 3, and creates a correct answer question based on the registration information selected from the read registration information by operating the input unit 33 of the facility staff member. The correct answer question is a correct answer question that expresses in a sentence that a specified result will be brought about if a hazardous event represented by a hazardous event wording occurs in a situation represented by a situation wording. The question creation unit 213 also creates an incorrect answer question based on the correct answer question. Specifically, the question creation unit 213 creates an incorrect answer question by replacing the specified result in the correct answer question with a result different from the specified result in the result group. The question creation unit 213 stores (saves) the created correct answer question and incorrect answer question in the storage unit 22.

[0031] The question creation unit 213 creates a supplementary question sentence that indicates that a countermeasure expressed in a countermeasure phrase should be taken in a situation expressed in a situation phrase, based on the registered information, in response to an operation of the input unit 33 of the work registration terminal 3 by the facility staff member. The question creation unit 213 also reads out registered information according to the purpose of the question from the storage unit 22, and creates a question based on the read-out registered information. The question creation unit 213 stores (saves) the created question in the storage unit 22.

[0032] In response to a worker to whom questions are to be sent logging in to the terminal device 4, the question management unit 214 controls the communication unit 23 to read all questions to be sent and their correct answers from the questions stored in the storage unit 22 and send them to the terminal device 4. Note that since the terminal device 4 can determine whether an answer is incorrect based on the correct answer for the worker's answer to a question, the question management unit 214 needs only to send the correct answers to the terminal device 4 together with the questions, but it may also send the incorrect answers together.

[0033] In response to the worker logging in to the terminal device 4, the work information management unit 215 controls the communication unit 23 to send the confirmation information stored in the memory unit 22 together with the above-mentioned question to the terminal device 4. Furthermore, when the communication unit 23 receives the work result sent from the terminal device 4, the work information management unit 215 stores the work result in the memory unit 22. In response to the operation of the input unit 33 by the facility staff member, the work information management unit 215 reads the work result from the memory unit 22 and controls the communication unit 23 to send the work result to the work registration terminal 3.

[0034] The storage unit 22 stores the above-mentioned questions, their correct answers, confirmation information, and master data. The master data includes the above-mentioned result groups and related information. The storage unit 22 also functions as a storage unit that stores and preserves the above-mentioned work results. The storage unit 22 also stores and manages the above-mentioned registration information for each of the facilities F1 to Fn.

[0035] The communication unit 23 communicates with the management terminal 1 and the work registration terminal 3 via the Internet 100. The communication unit 23 also communicates with the terminal devices 4 in the facilities F1 to Fn via the Internet 100. As a result, the communication unit 23 transmits the above-mentioned problems and confirmation information to the terminal devices 4, and receives the above-mentioned work results from the terminal devices 4.

[0036] <Administrative terminal> The management terminal 1 is located in a management facility that manages all of the facilities F1 to Fn, and is operated by an administrator. The management terminal 1 has a control unit 11, a display unit 12, an input unit 13, and a communication unit 14. The communication unit 14 communicates with the cloud server 2 via the Internet 100.

[0037] Control unit 11 controls display unit 12, input unit 13, and communication unit 14 so that management terminal 1 functions as an operation terminal for operating cloud server 2. Control unit 11 accepts input operations on input unit 13 by the administrator and controls communication unit 14 to access cloud server 2. Control unit 11 acquires image information from cloud server 2 that is generated as a result of a control operation performed by control unit 21 of cloud server 2 in response to the access, and displays the image information on display unit 12. In this way, by functioning as an operation terminal, management terminal 1 can register, edit, and view master data, view various types of information about facilities F1 to Fn, register a new facility F, and so on, on cloud server 2.

[0038] Specifically, the addition, deletion, and modification of the master data of the results in the result group are performed by the administrator. The administrator also registers related information in the master data. The administrator has all the authority to perform the work.

[0039] <Work registration terminal> The work registration terminal 3 is placed in each of the facilities F1 to Fn and is operated by a facility staff member. The work registration terminal 3 has a control unit 31, a display unit 32, an input unit 33, and a communication unit 34. The communication unit 33 communicates with the cloud server 2 via the Internet 100.

[0040] Control unit 31 controls display unit 32, input unit 33, and communication unit 34 so that work registration terminal 3 functions as an operation terminal that operates cloud server 2. Control unit 31 accepts input operations on input unit 33 by facility staff, and controls communication unit 34 to access cloud server 2. Control unit 31 acquires image information from cloud server 2 that is generated as a result of a control operation performed by control unit 21 of cloud server 2 in response to the access, and displays the image information on display unit 32. In this way, work registration terminal 3 functions as an operation terminal, allowing quiz creation and the like to be performed on cloud server 2.

[0041] The display unit 32 displays various screens generated by the cloud server 2. An example of such a screen is a question creation screen. The question creation screen is a screen on which the facility staff member inputs information required to create a question and displays a list of registration information to be selected by the facility staff member.

[0042] The input unit 33 accepts input operations on the various screens displayed by the display unit 32.

[0043] Terminal Device The terminal device 4 includes a control unit 41 , a display unit 42 , an input unit 43 , a camera 44 , and a communication unit 45 .

[0044] The control unit 41 controls the operation of each unit of the terminal device 4. The display unit 42 displays a GUI (Graphical User Interface) screen for displaying the above-mentioned questions and answering the questions, a GUI screen for displaying the above-mentioned confirmation information and accepting operations, and a GUI screen for entering work results and sending them to the cloud server 2. The input unit 43 is composed of an input device such as a touch panel, and accepts operations on the display surface of the display unit 42. The camera 44 is used to capture images of the work status, work results, etc.

[0045] The communication unit 45 communicates with the cloud server 2 via the Internet 100. When the communication unit 45 is online, it appropriately transmits transmission information such as answers to questions, which will be described later, and work results under the control of the control unit 41. Furthermore, the communication unit 45 does not transmit information when offline, but transmits the information collectively under the control of the control unit 41 when the online state is restored.

[0046] <Information management> The management of information about work by the information management system 101 configured as above will now be described.

[0047] FIG. 4 is a flowchart showing the procedure of each process performed by the cloud server 2 and the terminal device 4. FIG. 5 is a flowchart showing the procedure of the registration process among the processes. FIG. 6 is a flowchart showing the procedure of the question creation process among the processes. FIG. 7 is a diagram showing the configuration of questions created by the question creation process. FIG. 8 is a flowchart showing the procedure of the question setting process among the processes. FIG. 9 is a diagram showing the transition of various screens related to the answers to questions, which are displayed on the terminal device 4 in the information management system 101. FIG. 10 is a flowchart showing the procedure of the work management process among the processes.

[0048] <Overall processing overview> 4, first, the registration management unit 212 of the cloud server 2 performs a registration process to register registration information in response to operation of the input unit 33 by the facility staff member on the work registration terminal 3 (step S1). Once the registration of the registration information is complete, the question creation unit 213 of the cloud server 2 performs a question creation process to create questions in response to operation of the input unit 33 by the facility staff member on the work registration terminal 3 (step S2). Once the question creation is complete, the question management unit 214 and the terminal device 4 perform a question setting process to present the questions to the worker and determine whether the answers to the questions are correct or not (step S3). Once the question setting is complete, the work information management unit 215 and the terminal device 4 perform a work management process to manage the worker's work based on the confirmation information (step S4).

[0049] In this way, the registration process, question creation process, question setting process, and work management process are carried out in a sequential order, which allows for efficient planning and execution of work.

[0050] <Registration process> First, by accessing the cloud server 2 from the work registration terminal 3, a registration screen (not shown) generated by the registration management unit 212 of the cloud server 2 is displayed on the display unit 12 of the work registration terminal 3. The facility staff member described above uses the input unit 33 to input hazardous event words and situation words as hazard prediction items in a free-form format on the registration screen, and also inputs countermeasure words in a free-form format. As shown in Fig. 5, the registration management unit 212 accepts the hazard prediction items and countermeasure words input from the work registration terminal 3 (step S11).

[0051] The registration management unit 212 associates the hazard prediction items with the selected designation results and registers them in the memory unit 22 (step S12). The facility staff member operating the work registration terminal 3 inputs the hazard event wording, situation wording, countermeasure wording, and work content on the registration screen, refers to the master data, selects and designates one from the result group, and selects the type of work for the related information. The registration management unit 212 registers the registration information based on the various information input, designated, and selected on the registration screen. Note that basic registration information that does not include countermeasure wording may be registered as registration information, and registration information that includes countermeasure wording may be registered separately.

[0052] Furthermore, the registration management unit 212 stores the work information and the registration information in association with each other in the storage unit 22 (step S13), and returns the process to the main routine of FIG.

[0053] The registration management unit 212 associates the work content with related information and registers it in advance as work information in the storage unit 22 (not shown). Therefore, the facility staff completes the work information registration work before starting the work. In addition, the related information is registered in advance in the storage unit 22 of the cloud server 2 by the administrator operating the management terminal 1 (not shown).

[0054] When registration information is registered at one facility F, the registration management unit 212 registers the registration information at other facilities F and shares it.

[0055] <Question Creation Process> First, the facility staff member who will be the quiz creator operates the input unit 33 of the work registration terminal 3, causing the work registration terminal 3 to access the quiz creation unit 213 of the cloud server 2. As shown in FIG. 6 , the quiz creation unit 213 displays a quiz creation screen (not shown) on the display unit 32 of the work registration terminal 3 in response to the access from the work registration terminal 3 (step S21). Next, the quiz creation unit 213 determines whether a work type has been input on the quiz creation screen (step S22). If the quiz creation unit 213 determines in step S22 that a work type has not been input (NO), it waits for the type to be input. If the quiz creation unit 213 determines in step S22 that a work type has been input (YES), it displays a list of registered information on the quiz creation screen (step S23).

[0056] Next, the question creation unit 213 determines whether or not the facility staff member has selected registered information from the list of registered information (step S24). If the question creation unit 213 determines in step S24 that registered information has not been selected (NO), it waits for the selection of registered information. Registered information is associated with related information. This allows the facility staff member to find and select desired registered information based on the work content by referring to the related information corresponding to the work content on the question creation screen.

[0057] In step S24, if the question creation unit 213 determines that registered information has been selected (YES), it creates a question based on the selected registered information (step S25). Then, the question creation unit 213 stores the created question in the storage unit 22 (step S26), and returns the processing to the main routine. When registered information is selected on the question creation screen by the facility staff, the question creation unit 213 creates a question as follows.

[0058] When creating questions, the question creation unit 213 applies the dangerous event wording, situation wording, and specified result included in the registered information to a fixed phrase, and creates a question sentence with a meaning such as "When a 'dangerous event' occurs in a 'situation wording,' it brings about a 'specified result.'" For example, if the dangerous event wording is "your feet will slip," the situation wording is "rain," and the specified result is "you will fall," the question creation unit 213 creates a question such as "If your feet slip in the rain, you will fall."

[0059] The question creation unit 213 creates such questions as correct answer questions, and also creates incorrect answer questions in response to requests from facility personnel. The question creation unit 213 creates incorrect answer questions by replacing the specified result in the correct answer question with a result different from the specified result in the result group. For example, the question creation unit 213 replaces the specified result "fall" in the correct answer question in the above example with the different result "get caught up" to create an incorrect answer question such as "If your feet slip when it rains, you will get caught up."

[0060] When creating questions, the question creation unit 213 creates a question supplemental sentence that expresses taking the countermeasure expressed in the countermeasure phrase in the situation expressed in the situation phrase. For example, if "walk with fewer steps" is registered as the situation phrase along with the dangerous event phrase and situation phrase in the above example, the question creation unit 213 creates a question supplemental sentence that reads "walk with fewer steps when it rains."

[0061] When creating questions, the question creation unit 213 creates questions according to the question purpose. As shown in FIG. 7, the registered information registered in the storage unit 22 includes information associated with the question purpose "normal (normal work)," information associated with the question purpose "emergency (emergency work)," and information associated with the question purpose "education." The registered information may differ between question purposes in at least one of the dangerous event wording, the situation wording, and the specified result, or may all be the same (for example, the first, third, and fifth columns of the registered information). The number of registered information associated with the question purpose "normal," the question purpose "emergency," and the question purpose "education" is predetermined.

[0062] Based on the registration information registered in this way, the question creation unit 213 creates questions with a specified number of questions n1 for the question purpose of "normal", creates questions with a specified number of questions n2 for the question purpose of "urgent", and creates questions with a specified number of questions n3 for the question purpose of "education". Among the specified numbers of questions for each, there is a magnitude relationship of n2 < n1 < n3.

[0063] For example, in the case of the question purpose of "normal", about 10 questions are created as the standard number of questions. In the case of the question purpose of "urgent", due to the need to rush the work, it is not possible to answer as many questions as in the case of "normal", but from the perspective of improving safety, the number of questions is narrowed down to about 5 questions compared to the case of the question purpose of "normal". In the case of the question purpose of "education", about 15 questions are created in order to enhance the educational effect of the danger prediction activity. These numbers of questions are only examples, and it is of course understood that the number of questions is not limited to these examples.

[0064] 〈Question Issuance Process〉 As shown in FIG. 8, first, the question management unit 214 determines whether the operator has logged in to the terminal device 4 (step S31). In step S31, if the question management unit 214 determines that the operator has not logged in to the terminal device 4 (NO), it waits for the login. The question management unit 214 recognizes the login based on the notification from the terminal device 4 when the operator logs in to the terminal device 4.

[0065] In step S31, if the question management unit 214 determines that the operator has logged in to the terminal device 4 (YES), the communication unit 23 transmits all the questions created as described above and stored in the storage unit 22, and their correct answers, together with the work content, to the terminal device 4 under the control of the question management unit 214 (step S32).

[0066] The terminal device 4 receives the questions and correct answers sent from the cloud server 2 via the communication unit 23 (step S33). The control unit 41 of the terminal device 4 presents a question in response to an operation by the worker to start asking a question, and upon receiving the answer from the worker, determines whether the answer is correct or not and presents the next question, i.e., presents a question and determines whether the answer is correct or not (step S34).

[0067] Next, the control unit 41 determines whether the correctness of the answers to all the questions has been determined (step S35). If the control unit 41 determines in step S35 that the correctness of the answers to all the questions has not been determined (NO), it continues the determination. If the control unit 41 determines in step S35 that the correctness of the answers to all the questions has been determined (YES), it notifies the worker of the correctness / incorrectness determination result by displaying it on the display unit 42 (step S36), and the process returns to the main routine.

[0068] Next, the screen display on the terminal device 4 for answering the questions and the interaction between the cloud server 2 and the terminal device 4 will be described.

[0069] As shown in FIG. 9, when answering a question, first, the control unit 41 of the terminal device 4 causes the display unit 42 to display an initial screen 201. The initial screen 201 includes a task content display area 201a, a previous score display area 201b, and a start button 201c. The task content display area 201a lists the task content and the worker (name) for the task to be performed. The worker is registered in advance in the cloud server 2 as the worker who will perform the task to be performed. The previous score display area 201b lists the score for the previous question. The start button 201c is an operation button for starting the question.

[0070] When the start button 201c on the initial screen 201 configured as above is operated by the worker (registered worker) who owns the terminal device 4, the control unit 41 causes the display unit 42 to display the question screen 202.

[0071] The question screen 202 includes a task content display area 202a, a question display area 202b, a correct answer button 202c, and an incorrect answer button 202d. The task content display area 202a describes the task content for the task to be performed. The question display area 202b describes the question and a solution. The correct answer button 202c is an operation button for inputting an answer that the question is correct. The incorrect answer button 202d is an operation button for inputting an answer that the question is incorrect.

[0072] When the operator operates the correct answer button 202c or the incorrect answer button 202d on the question setting screen 202 configured as described above, the control unit 41 controls the display unit 42 to display the next question on the question setting screen 202. The control unit 41 repeats this process for all questions.

[0073] Each time an answer to a question is input, the control unit 41 determines whether the answer is correct or incorrect through the process of step S35.

[0074] If the answer is correct, the control unit 41 of the terminal device 4 causes the display unit 42 to display the question screen 202 that displays the next question. If the answer is incorrect, the control unit 41 causes the display unit 42 to display the question screen 202 that displays the next question, after temporarily displaying the correct answer in, for example, the question display area 202b of the question screen 202 that includes the answered question.

[0075] The control unit 41 causes the display unit 42 to display a result screen 203 including the result of the judgment of whether the answer is correct or incorrect as described above. The result screen 203 includes a task content display area 203a, a result display area 203b, a correct answer list display button 203c, and an end button 203d.

[0076] The work content display area 203a lists the work content for the work to be performed. The result display area 203b lists the score for the current question and the score for the previous question, but the correct answer rate for the current question may be listed instead of the score. The control unit 41 lists the score for the current question in the result display area 203b based on the final result. The correct answer list display button 203c is an operation button for displaying a list of the questions and correct answers asked on the day of the work. The end button 203d is an operation button for ending the question setting.

[0077] When the worker operates the correct answer list display button 203c on the result screen 203 configured as described above, the control unit 41 causes the display unit 42 to display a screen (not shown) showing a list of all presented questions and the correct answers to those questions. This allows the worker to look back on their own answers to past questions.

[0078] The control unit 41 ends the question setting process when the worker operates the end button 203d on the result screen 203. Furthermore, the control unit 41 causes the communication unit 45 to send the answer results of the question to the cloud server 2 while the terminal device 4 is online.

[0079] In this way, when the worker logs in to the terminal device 4, the questions and correct answers are sent all at once from the cloud server 2 to the terminal device 4. This allows the terminal device 4 to set questions and determine whether the answers are correct or not while offline. The terminal device 4 can also provide the answer results for the questions when it becomes online.

[0080] <Work management processing> As shown in FIG. 10, first, the work information management unit 215 determines whether or not the worker has logged in to the terminal device 4 (step S41). If the work information management unit 215 determines in step S31 that the worker has not logged in to the terminal device 4 (NO), it waits for the worker to log in. On the other hand, if the work information management unit 215 determines in step S41 that the worker has logged in to the terminal device 4 (YES), it causes the communication unit 23 to transmit the above-mentioned confirmation information all at once to the terminal device 4 (step S42). Here, the confirmation information may include information about items required for the work, information about precautions to take before work, a work procedure manual, and information about precautions to take after work.

[0081] The confirmation information may be transmitted to the terminal device 4 together with the question and the correct answer. In this case, the question management unit 214 may control the communication unit 23 to transmit the confirmation information together with the question and the correct answer, or the work information management unit 215 may control the communication unit 23 to transmit the confirmation information together with the question and the correct answer.

[0082] When the question setting process is completed as described above, the control unit 41 of the terminal device 4 causes the display unit 42 to display a screen (not shown) that displays the items necessary for the work based on the information about the items necessary for the work (step S43). The information about the items necessary for the work includes photo data about the items necessary for the work, such as tools, and text data about the names of the items necessary for the work. This allows the worker to confirm the items necessary for the work.

[0083] Next, when the operator performs an operation to transition to the next screen on the screen displaying the items required for work, the control unit 41 causes the display unit 42 to display a screen (not shown) displaying the contents of the precautions to be taken before work based on the information to be taken before work (pre-work caution information) (step S44). The pre-work caution information may include image data showing actions that can lead to accidents before work, text data explaining the actions, etc. This allows the worker to take action to avoid an accident.

[0084] Next, when the operator performs an operation to transition to the next screen on the screen displaying the precautions to be taken before work, the control unit 41 causes the display unit 42 to display a screen (not shown) displaying the work procedure manual based on the work procedure manual (data) (step S45). The work procedure manual describes the work procedures in a slide format so that they can be displayed in a movable manner. This allows the worker to check the work procedures before and during work.

[0085] Furthermore, when the operator performs an operation to transition to the next screen on the screen displaying the work procedure manual, the control unit 41 causes the display unit 42 to display a screen (not shown) that displays post-work cautions based on post-work caution information (post-work caution information) (step S46). Examples of post-work caution information include image data showing actions that may lead to post-work accidents, text data explaining the actions, etc. This allows the worker to take action to avoid an accident.

[0086] Thereafter, when the operator performs an operation to transition to the next screen on the above screen that displays the contents to be noted after the work, the control unit 41 causes the display unit 42 to display a work result input screen (not shown) (step S47).

[0087] The work result input screen indicates that the work has been completed, and also includes a field for entering messages (message entry field) and a send button. The worker can then enter messages about the completed work in the message entry field as needed and press the send button. In response to this operation, the terminal device 4 causes the control unit 41 to control the communication unit 45 to send a work completion notification, including the messages, to the cloud server 2 as the work result (step S48).

[0088] Then, the work information management unit 215 stores the work results received from the terminal device 4 in the storage unit 22 (step S48), and returns the process to the main routine of FIG.

[0089] In this way, in the work management process, the terminal device 4 displays the items required for work, pre-work caution information, work procedure manual, and post-work caution information in response to the worker's operation based on the confirmation information transmitted collectively by the work information management unit 215 of the cloud server 2. Furthermore, even if the worker closes each screen after checking the contents of each of the above-mentioned screens, the worker can display the screen again by operating it.

[0090] This allows confirmation information to be provided to the terminal device 4 before, during, and after work. This allows the worker to obtain the necessary information at the desired timing at each stage of work, allowing the work to be carried out smoothly.

[0091] Furthermore, the cloud server 2 stores the work results sent from the terminal device 4 in the storage unit 22. This makes it possible to easily collect the work results from the workers. The work registration terminal 3 can view the work results for each worker stored in the storage unit 22 by requesting the cloud server 2 to view them.

[0092] In addition, in the terminal device 4, the process of causing the control unit 41 to display the above-mentioned screens on the display unit 42 is performed by executing an application program installed in the terminal device 4. The application program is also created to perform the process of displaying the above-mentioned initial screen 201, question screen 202, and result screen 203.

[0093] As a result, by answering the questions before starting work, the worker can deepen his / her understanding of the hazard prediction items for the work he / she is about to do, and can confirm the necessary items for the work, the points to be careful of before the work, and the work procedure. In addition, the worker can confirm the work procedure while working, and after the work, the points to be careful of after the work, and can also send the work results to the cloud server 2. Then, by performing such a series of routines on the terminal device 4, the efficiency of the work can be improved.

[0094] <Effects of the information management system> As described above, in the information management system 101 according to this embodiment, the cloud server 2 includes the registration management unit 212 and the question creation unit 213. The registration management unit 212 stores registration information that associates dangerous event phrases, dangerous event phrases, and designation results in the storage unit 22. The question creation unit 213 reads out the selected registration information from the storage unit 22, and creates correct-answer questions based on the read registration information.

[0095] In the above configuration, an answer that determines a correct answer question to be correct (for example, ○) is the correct answer, and an answer that determines a correct answer question to be incorrect (for example, ×) is the incorrect answer. Such questions can be registered by a work manager or person in charge who has a concrete understanding of the work content, by associating the dangerous event wording and situation wording, which are risk prediction items that take the work content into consideration, with the specified result. This makes it easy to create questions that are in line with the work content.

[0096] The question creation unit 213 may create only correct answer questions as questions, but it is preferable to create additional incorrect answer questions in which the specified results in the correct answer questions are replaced with different results in the result group.

[0097] In the above configuration, an answer that determines whether a correct answer is correct (for example, ○) is the correct answer, and an answer that determines whether a correct answer is incorrect (for example, ×) is the incorrect answer. Such questions can be easily created by simply replacing the specified result of the correct answer question with a different result.

[0098] The registration management unit 212 associates words representing measures to avoid dangerous events (measure words) with dangerous event words, situation words, and designation results, and stores them as registration information in the storage unit 22. Furthermore, the question creation unit 213 creates a question supplement sentence representing taking the measures represented by the measure words in the situation represented by the situation words, based on the registration information.

[0099] According to the above configuration, it is possible to confirm countermeasures in conjunction with the questions, thereby making it possible for the worker answering the questions to recognize actions to take to avoid danger.

[0100] The registration management unit 212 stores the work information, in which the related information is associated with the work content, and the registration information in the storage unit 22 in a state in which the related information and the registration information are associated with each other.

[0101] With the above configuration, various elements included in the work information can be treated as related information. As described above, the related information includes, for example, the type of work and events that affect the work (weather influences, health abnormalities, etc.). Facility personnel can find the desired registered information by referencing the related information corresponding to the work content. This allows facility personnel to easily create questions using the cloud server 2.

[0102] The registration management unit 212 associates the question purpose with a predetermined number of pieces of registered information for each question purpose and stores them in the storage unit 22. The question creation unit 213 reads out registered information corresponding to the question purpose from the storage unit 22 and creates questions based on the read registered information.

[0103] According to the above configuration, questions can be created according to the purpose of the questions. For example, if the purpose of the questions is to have workers recognize hazard prediction information for work to be performed, a standard number of questions can be created for work scheduled for tomorrow with a normal level of urgency. On the other hand, for work with a high level of urgency, fewer questions than the standard number can be created by focusing on hazard prediction items that require particular attention in order to shorten the time required to answer the questions. Furthermore, if the purpose of the questions is to educate workers on hazard prediction activities, more questions than the standard number can be created because workers will not actually be performing the work and will have enough time to answer the questions.

[0104] The cloud server 2 includes a communication unit 23 that transmits the question and confirmation information to the terminal device 4 .

[0105] According to the above configuration, each worker can receive questions and answer them on the terminal device 4, and can also check the confirmation information on-site. This allows the work to be carried out smoothly.

[0106] The communication unit 23 receives the work results transmitted from the terminal device 4. Furthermore, the storage unit 22, under the control of the registration management unit 212, stores the received work results.

[0107] According to the above configuration, the cloud server 2 can easily collect the work results of each worker.

[0108] The storage unit 22 of the cloud server 2 stores registration information for a plurality of facilities F1 to Fn. When registration information for one facility F is newly registered, the registration management unit 212 causes the registration information to be newly registered for the other facilities as well.

[0109] According to the above configuration, for example, if registration information is registered for each facility F1 to Fn, newly registered information for a facility can be shared with other facilities. This allows a variety of registered information to be shared among all facilities F1 to Fn. This makes it possible to enrich the overall information related to hazard prediction for users of the information management system 101. Therefore, by creating questions based on such information, hazard prediction activities can be carried out more actively.

[0110] The information management system 101 includes a management terminal 1 and a cloud server 2. The management terminal 1 accepts input of a dangerous event wording and a situation wording, and notifies the cloud server 2 of the input dangerous event wording and situation wording. The registration management unit 212 of the cloud server 2 stores in the storage unit 22 registration information that associates the notified dangerous event wording, the notified situation wording, and the designation result.

[0111] According to the above configuration, the registration information can be registered by inputting the dangerous event message and the situation message into the management terminal 1 that is provided in a location different from the location where the cloud server 2 is installed.

[0112] The information management system 101 includes a cloud server 2 and a work registration terminal 3. The work registration terminal 3 accepts an operation to select registration information in the storage unit 22, and notifies the cloud server 2 of the registration information selected by the operation. The question creation unit 213 of the cloud server 2 reads the notified registration information from the storage unit 22, and creates questions based on the read registration information.

[0113] According to the above configuration, questions can be created in the cloud server 2 by operating the work registration terminal 3 in the facilities F1 to Fn that are located in different places from where the cloud server 2 is installed. This eliminates the need for each of the work registration terminals 3 in the facilities F1 to Fn to have a question creation function. This allows the information management system 101 to be configured simply.

[0114] [Software implementation example] The functions of cloud server 2 (hereinafter referred to as "device") can be realized by a program that causes a computer to function as the device. The program causes a computer to function as each control block of the device (particularly, registration management unit 212 and question creation unit 213).

[0115] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing each function described in the above embodiment.

[0116] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0117] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit on which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention.

[0118] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may be operated by the control device or another device (such as an edge computer).

[0119] [Additional Notes] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Furthermore, embodiments obtained by appropriately combining the technical means disclosed in the embodiments are also included in the technical scope of the present invention.
