Description

  The present invention relates to an information collection system that collects on-site data generated in a factory or office.

  Various facilities are operating in factories, offices, and the like, and a data generator that monitors the facilities outputs field data indicating observation results for the facilities such as observation values, error information, and status information. The data generation device is a facility sensor, a programmable logic controller that controls factory automation (FA), a computer that counts products, a mobile terminal that allows a user to input information, and the like.

  The on-site data is output as a numerical value that is coded or an observation result, and is monitored by the fixed asset manager as event information to which the occurrence location and date / time information is added. The fixed asset manager is, for example, a facility maintenance manager in a factory and a facility manager such as a server in an office.

  This event information is valuable information that contributes to operations such as factory and office operation management, product quality management, and business management. However, the event information output directly from the facility does not have secondary or tertiary meanings other than the direct meanings such as codes or simple observation numerical values, occurrence location and occurrence date and time. Conventionally, the information obtained at the site level is sequentially re-interpreted at each layer until it reaches the management and management level, and event information is changed into information with secondary and tertiary meanings. The event information was used at each level. Therefore, a time lag tends to occur in the way of information transmission between the site level and the management or management level, and the site level and the business management level tend to be liberated.

  Therefore, the applicant has proposed an information collection system that can share event information in real time at each level as in Japanese Patent Application No. 2011-104532. This information collection system stores a dictionary in which models that define the types of supplementary information added to field data are accommodated. In addition, a database storing supplementary information of various contents is prepared. Then, according to the dictionary, each supplementary information is searched from the database, and each searched supplementary information is added to the field data to generate event information.

  In the search, other types of supplemental information of optimum contents are searched using various combinations of the field data included in the event information and each of the added supplemental information as search keys. That is, the information collection system proposed by the applicant adds the supplementary information having the optimum contents to the contents of the field data and the contents of each supplementary information added so far, using the field data as a starting point.

  As a result, the event information includes not only simple background information for the field data but also explanatory information such as interpretation and evaluation of the contents of the field data, and has immediacy in information transmission. In other words, from the user side, it seems that the event information describing the required contents directly and in an easy-to-understand manner has occurred, and when the event information arrives without requiring any interpretation work, Can understand secondary and tertiary meanings of information. Therefore, from the on-site level to the business management level, not only the arrival time lag of event information but also the understanding time lag of event information can be eliminated.

  In factories and offices, it is not only sensors and programmable logic controllers that capture specific events that occur on site. At the site, video cameras that shoot the entire site or local area, still cameras that shoot still images, and microphones that record audio are installed, and these devices also record specific events. is there. It would be very beneficial if recorders such as video cameras, still cameras, and microphones were also incorporated in the information collection system as data generators, and recording data generated by these recorders could be used as field data to generate event information.

  For example, before a fire alarm detects a fire from smoke or temperature, a video camera or the like often catches small flames or sparks. That is, the range recorded by the recorder is very wide. For example, if the fire spread does not spread to the vicinity of the temperature sensor installation location, the temperature sensor cannot detect a fire. On the other hand, since the camera can set not only the installation location of the temperature sensor but also a wide area including the installation location, the fire is often recorded earlier than the temperature sensor. In addition, the collision between operating objects can be sensed by stopping the operating object or abnormal motor torque of the operating object, but when the operating object stops or the motor torque does not become abnormal, a collision sound is generated. In many cases, the microphone records the collision between the working objects earlier than these.

  However, in order to generate event information by adding appropriate background information and explanation information to the site data, the information collection system must understand the meaning of the site data, but the recording data output from the recorder is However, it cannot be said to be on-site data that can directly grasp the meaning. The first reason is that the recording data is not only a single specific object but also a large amount of bulk data recorded other than the specific object. Second, the display position, the display time zone, and the recording time zone of the specific object may not be constant, and settings for distinguishing the specific object itself from noise cannot be taken in advance. Thirdly, the specific object itself does not have a fixed shape, and a regulation code representing the specific object cannot be determined in advance.

  For example, in a video showing a flame, only the flame is not always shown. Flames do not always appear at certain times. The flame does not take a certain shape. That is, the image, the moving image, and the audio data include data other than the specific object, and are data in which the specific object and the noise are mixed in an indistinguishable directly, so that the semantic content cannot be directly grasped.

  For this reason, conventionally, recording data such as images, moving images, and audio data has only been handled as background information or explanatory information added to other field data such as sensor temperature information. Or, the history of image, video, and audio data, such as shooting / recording time and camera / microphone installation location, is handled as on-site data, and it is only treated as background information or explanatory information added to the on-site data. It was. Thus, conventionally, it has not been possible to generate event information in which a background or explanation is added to a specific event captured by an image, a moving image, or audio data.

The PLC monitors statuses such as product process completion and errors, for example. That is, the data generation device 100 generates the field data 100a. The field data 100a is observation results for equipment and products such as observation result information, lot number information, or status information.

  The recorder 200 is installed to monitor the state of the site such as a factory or office. The recorder 200 includes a video camera main body, a camera main body that captures a still image, or a microphone main body, and a computer or a microcomputer, and can transmit data via the network 300. The recorder 200 shoots a moving image or a still image or records a sound, and generates recording data 200a that is moving image data, image data, or sound data.

  The data generation device 100 and the recorder 200 add their transmission source IP addresses to the field data 100a and the recording data 200a, and use TCP or IP including the IP address of the information collection system 1 and the port number of the information collection application as a destination address. A header is added and sent to the network 300.

  The information collection system 1 generates event information 1a by adding various supplementary information 2a to the on-site data 100a generated by the data generator 100. Further, the information collection system 1 analyzes the recording data 200a, generates on-site data 100a from the analysis result, and adds various supplementary information 2a to the generated on-site data 100a, thereby obtaining the event information 1a. To construct. The event information 1a is a series of data in which supplementary information 2a is added to the field data 100a. The supplementary information 2a is information that supplements the content of the on-site data 100a, and is background information of event occurrence, explanation information of the occurrence event, analysis information of the occurrence event, or other various useful information.

  The database 2 stores supplementary information 2a of various contents in association with the on-site data 100a and other supplementary information 2a. The information collection system 1 searches the database 2 as a database management system (DBMS), and acquires supplementary information 2a.

  The information collection system 1 and the database 2 are configured to include a computer, and include a processor such as a CPU and an MPU, a RAM, an OS, an external storage device such as an HDD and an SSD in which an information collection application is stored, and a network adapter. . The information collection system 1 is a single computer or a distributed computer group. The information collection system 1 and the database 2 are separate computers that are integrated or distributed on the network 300.

  The information collection application is a program code or a control program that causes a computer to function as the information collection system 1, and is specifically an object code or a machine language instruction. This program code or control program may be stored in a manner written in various source code programming languages and then compiled or assembled into executable machine code or instructions suitable for the processor. This application is stored in a portable storage medium such as a CDROM, DVDROM, or USB memory, or a storage medium on a network such as a server, and installed in an external storage device. The computer constituting the information collection system 1 has a drive capable of reading a portable storage medium, and is connected to the network so as to be accessible to a storage medium on the network such as a server.

  FIG. 2 is a block diagram showing the configuration of the information collection system 1. The information collection system 1 processes an application of an external storage device with a processor, thereby allowing a memory 11, an analysis engine 12, a feature storage unit 13, a change detection engine 14, a dictionary storage unit 15, and an event information generation unit. 16, a system design support terminal 17, and a field data storage unit 18.

  The memory 11 includes a RAM or an external storage device. The memory 11 temporarily stores the on-site data 100a and the recording data 200a sent to the network 300.

  The analysis engine 12 includes a processor and an external storage device. The analysis engine 12 refers to the feature storage unit 13 and analyzes the recording data 200 a stored in the memory 11. The analysis content is the occurrence of a specific event. For example, the appearance of a specific object, a change in the form of a specific object, the appearance of an unspecified object, or a combination thereof is analyzed. If the occurrence of the specific event is recorded in the recording data 200a, the analysis engine 12 stores the field data 100a indicating the occurrence of the specific event in the memory 11.

  A standard pattern 131 is stored in the feature storage unit 13. The standard pattern 131 shows the characteristics of a specific object. The standard pattern 131 is a shape information that forms a specific object or a specific character by arranging feature points two-dimensionally with respect to still image data or moving image data, color information of the specific object or a specific character, or a combination thereof. is there. The standard pattern 131 is the frequency, amplitude, timbre, spectrum, or combination thereof of the specific sound with respect to the sound data.

  For example, the standard pattern 131 is a combination of shape information indicating the shape of a helmet and color information such as yellow in order to distinguish a guard wearing a yellow helmet from the data. The analysis engine 12 converts each frame of the recording data 200a into an array of feature points and a distribution of color information, and collates each area of the frame with the standard pattern 131. When the arrangement of feature points in one region and the distribution of color information match the standard pattern 131, the analysis engine 12 stores the field data 100a indicating the specified contents in the memory 11. The on-site data 100a indicating the prescribed content is, for example, text data indicating arrival of a guard, and is stored in advance in the on-site data storage unit 18.

  Further, for example, the standard pattern 131 is spectrum data of a cutting sound that a metal rubs in order to specify from data that the transport facility and the product to be transported collide with each other. The analysis engine 12 collates the spectrum data of each time interval of the recording data 200a with the standard pattern 131. Then, for example, as a result of the match, field data 100a composed of text data indicating the occurrence of abnormal noise is stored in the memory 11.

  The change detection engine 14 includes a processor and an external storage device. The change detection engine 14 analyzes the recording data 200a stored in the memory 11. The analysis content is a change in the situation captured by the recorder 200. If a change is recorded in the recording data 200 a, the change detection engine 14 reads out the site data 100 a indicating the occurrence of the change from the site data storage unit 18 and stores it in the memory 11.

  That is, the change detection engine 14 compares the still image, frame, or sound at each time point recorded by the recording data 200a with the still image, frame, or sound at the previous time point. The change detection engine 14 stores on-site data 100a indicating a change in the memory 11 due to a difference of a certain level or more to be compared. The on-site data storage unit 18 stores in advance text data indicating the occurrence of a change.

  The event information generation unit 16 includes a processor. The event information generation unit 16 refers to the dictionary storage unit 15 and acquires the supplemental information 2a from the database 2 or the memory 11, thereby generating the event information 1a. The supplementary information 2 is typically acquired from the database 2, but may be acquired from, for example, the memory 11 or a collection location of the already generated event information 1 a if the event information generation unit 16 is accessible. It may be.

  As shown in FIG. 3, the event information 1a is a series of data in which supplementary information 2a is linked with the field data 100a stored in the memory 11 as a core. In addition to the information stored in the database 2, the on-site data 100a, the recording data 200a stored on the memory 11, the on-site data 100a and part of the recording data 200a, and already generated event information 1a are also handled as supplementary information 2a. You may do it.

  The dictionary storage unit 15 includes an external storage device, and stores a model 151 of event information 1a according to the type of the on-site data 100a. FIG. 4 is a schematic diagram showing the model 151 stored in the dictionary storage unit 15. The model 151 includes a plurality of supplement type information 152. The supplement type information 152 indicates the type of the supplement information 2a added to the event information 1a. Further, the model 151 has query information 154 as a pair with each supplement type information 152. The query information 154 is a search condition for narrowing down one supplementary information 2a from the group of supplementary information 2a belonging to the supplement type information 152. This model 151 is specified by the event type information 153. The event type information 153 indicates the type of the on-site data 100a that is the core of the event information 1a indicated by the model 151.

  The event information generation unit 16 searches the dictionary storage unit 12 for the model 151 using the event type information 153 that matches the type of the field data 100a stored in the memory 11 as a clue. The type of the on-site data 100a and the event type information 153 are, for example, the IP address of the data generating apparatus 100 that generated the on-site data 100a, or specific contents of the on-site data 100a.

  As illustrated in FIG. 5, the event information generation unit 16 identifies a group of supplementary information 2 a that is bundled with each supplement type information 152 included in the corresponding model 151. The event information generation unit 16 uses the query information 154 to narrow down the supplementary information 2a from the group. The query information 154 includes the type of the on-site data 100a, the content of the on-site data 100a, the content of the supplemental information 2a that has already been added, or a combination thereof, or an arithmetic expression that calculates a size comparison or match / mismatch using these as parameters, or The content of the supplementary information 2a selected according to a calculation result is shown. The event information generation unit 16 adds the supplemental information 2a that has been narrowed down to the event information 1a with the field data 100a as a core.

  For example, a model 151 of event information 1a including on-site data indicating temperature, supplementary information 2a indicating an allowable temperature range, and supplementary information 2a indicating normality or abnormality of the temperature indicated by the on-site data 100a is stored in the dictionary storage unit 15. Yes. The event information generation unit 16 adds supplementary information 2a indicating the allowable temperature range to the event information 1a including the field data 100a indicating the temperature. Further, the event information generation unit 16 compares the temperature indicated by the on-site data 100a with the allowable temperature range of the supplemental information 2a that has already been added in accordance with the query information 154, and the keyword specified according to the comparison result is retrieved from the database 2. Search, for example, narrow down to supplementary information 2a indicating normality, and further add to event information 1a.

  Here, the event information 1a is roughly classified into two types according to origin, usage, and required people. Event data 1a for operation centered on the site data 100a generated by the data generator 100 or the site data 100a generated by the analysis engine 12, and for the design centered on the site data 100a generated by the change detection engine 14 Event information 1a. The event information 1a for operation is information required for a person who is engaged in operations such as on-site, sales, back office or management. The design event information 1a is information necessary for a person who is involved in designing the standard pattern 131 and a person who is involved in designing the model 151 related to the event information 1a of the specific event extracted from the recording data 200a.

  That is, the design event information 1a for notifying that the content of the recording data 200a has been changed is referred to by the designer, the designer grasps the change as the occurrence of the specific event, and the specific event When it is determined that the event information 1a is necessary for the operation personnel, the standard pattern 131 for capturing the specific event from the recording data 200a, the site data 100a indicating the specific event extracted from the recording data 200a, and the site data A model 151 indicating supplementary information 2a to be added with 100a as a nucleus is created.

  Therefore, as shown in FIG. 6, a model 151 of event information 1a for design is stored in the dictionary storage unit 15, and this model 151 includes event type information indicating field data 100a that is text information of a changing ant. 153, for example, supplement type information 152 indicating the change time, supplement type information 152 indicating the place where the change occurred, and on-site data 100a of the data generator 100 (sensor A in the figure) in the vicinity of the change place. The supplement type information 152 shown, the supplement type information 152 showing the recording data 200a, and the like are included, and the query information 154 is associated with each supplement type information 152.

  On the other hand, the supplementary information 2a included in the event information 1a for operation is not limited to the supplementary information 2a for the direct department that can be utilized at the field level, but indirectly derived from the field data 100a to manage the sales activities. It is supplementary information 2a for indirect departments that can be used at various management levels, and supplementary information 2a for management judgment that can be used at the management level. The direct department mainly includes the manufacturing department and the manufacturing management department, and the indirect department includes departments such as general affairs, sales, accounting, and management. The supplement type information 152 indicating the supplement information 2a and the query information 154 are included in the model 151 of the event information 1a for operation.

  Next, as shown in FIG. 7, the system design support terminal 17 includes a processor and a man-machine interface with the designer. The man-machine interface is a terminal that accepts information to the designer and receives operation inputs from the designer. For example, a display device such as a liquid crystal panel, an organic EL panel, or a printer, and a keyboard, mouse, touch panel, voice input device, etc. It is an input device. This system design support terminal 17 supports the generation of the designer's model 151 and standard pattern 131. That is, the system design support terminal 17 includes a display unit 171, a model design tool 172, and a feature design tool 173.

  The display unit 171 includes a display device, and displays design event information 1a. The model design tool 172 includes a man-machine interface, creates a model 151 of event information 1a derived from the recording data 200a in accordance with the designer's input, and stores the created model 151 in the dictionary storage unit 15. The feature design tool 173 is configured to include a man-machine interface, creates a standard pattern 131 for extracting a specific event from the recording data 200a according to the designer's input, and stores the created standard pattern 131 in the feature storage unit 13.

(Operation)
The operation of such an information collection system 1 will be described. FIG. 8 is a flowchart showing an operation of generating the design event information 1a. First, as shown in FIG. 8, the recorder 200 generates the recording data 200a periodically or continuously (step S01), and transmits the recording data 200a to the information collection system 1 regularly or continuously (step S01). S02). When receiving the recording data 200a (step S03), the information collecting system 1 stores the received recording data 200a in the memory 11.

  The change detection engine 14 compares the preceding and following data on the time series included in the recording data 200a of the memory 11 (step S04). As a result of the comparison, if the preceding and succeeding data are different (step S04, Yes), the change detection engine 14 stores the text data indicating the change ant stored in the memory 11 as the field data 100a (step S05). ).

  The event information generation unit 16 detects the appearance of the site data 100a (step S06). Then, the event information generation unit 16 searches the dictionary storage unit 151 for the model 151 corresponding to the on-site data 100a indicating the changing ant (step S07). The event type information 153, which is a clue to the search, may be text data called a change ant, or information indicating that the change detection engine 14 has been generated is added to the on-site data 100a. May be.

  When the corresponding model 151 is specified, the event information generation unit 16 narrows down the group of supplementary information 2a that matches the supplement type information 152 included in the model 151 (step S08).

Further, in accordance with the query information 154 stored in the model 151 in a pair with the supplement type information 152, the supplement information 2a having specific contents is further narrowed down from the narrowed down group (step S09).

  When the supplementary information 2a having the specific contents is narrowed down, the event information generating unit 16 adds the narrowed-down supplementary information 2a to the event information 1a having the spot data 100a of the changing ant as a core (Step S10). For example, a variable-length data file is generated, and the field data 100a and the supplementary information 2a are added to the data file. The addition of the supplement information 2a in steps S08 to S10 is repeated until the addition of the last supplement type information 152 of the model 151 is completed (step S11).

When an object that matches the standard pattern 131 is found (step S25, Yes), the analysis engine 12 stores the field data 100a indicating the occurrence of a specific event stored in advance in the memory 11 (step S26).

  The event information generation unit 16 detects the appearance of the site data 100a (step S27). The event information generation unit 16 searches the dictionary storage unit 151 for the model 151 corresponding to the on-site data 100a indicating the occurrence of the specific event (step S28). The event type information 153 that is a clue to the search may be the content of the on-site data 100a itself, or a combination of the content of the on-site data 100a and the recording location of the recorder 200. The recording location may be, for example, a transmission source IP address added to the recording data 200a analyzed by the analysis engine 12.

  When the corresponding model 151 is identified, the event information generation unit 16 narrows down the group of supplementary information 2a that matches the supplement type information 152 included in the identified model 151 (step S29). Further, according to the search condition indicated by the query information 154 paired with the supplement type information 152, the supplement information 2a having specific contents is further narrowed down from the narrowed down group (step S30).

  When the supplementary information 2a having the specific content is narrowed down, the event information generating unit 16 adds the narrowed-down supplementary information 2a to the event information 1a having the on-site data 100a of the specific event occurrence as a core (Step S31). The addition of the supplement information 2a in steps S29 to S31 is repeated until the addition of the last supplement type information 152 of the model 151 is completed (step S32).

(effect)
As described above, the information collection system 1 connected to the recorder 200 that records the recording data 200a via the network 300 prepares the field data 100a indicating the occurrence of the specific event in advance, and the recording data 200a is used as the standard pattern. When the occurrence of a specific event is detected by scanning at 131, the on-site data 100 a is stored in the memory 11. The database 2 stores supplementary information 2a of various contents, and when the site data 100a appears in the memory 11, the event information 1a is generated using the site data 100a as a core. That is, the supplementary information 2a having contents corresponding to the specific contents of the on-site data 100a is searched from the database 2, and the searched supplement information 2a and the recording data 200a are included in the event information 1a having the on-site data 100a as a core.

  As a result, the event information 1a can be generated only from the recording data 200a, and the recorder 200 can be incorporated into the system as one of the data generators 100.

  Stores a model that identifies the type of supplemental information to be included in the event information according to the type of field data, and searches the group of supplemental information of the type indicated in the model for field data and supplemental information already included Narrow down other supplementary information as a key.

  That is, as a result of detecting a specific event from the recording data 200a, the event data 1a is generated immediately instead of immediately generating the event information 1a. Thereby, the field data 100a generated by the data generator 100 and the recording data 200a generated by the recorder 200 can be handled without distinction in the same system, and the system designer and the operation that requires the event information 1a can be performed. Convenience increases for those involved.

When the recording data 200a is analyzed and the occurrence of change is detected in the time series data before and after, the on-site data 100a indicating the change ant is stored in the memory 11.

  First, the system designer collects various information such as the characteristics and operating conditions of the equipment, the human and physical flow of the factory and office from the physical and human resources, examines the installation location of the recorder 200, and the recorder It is conceivable to design a model 151 of event information 1a based on the recording data 200a in anticipation of a specific event of interest recorded in the 200 recording data 200a.

  However, the collection of this material and the prediction of specific events based on the collection results are very labor-intensive tasks involving trial and error. In this information collection system 1, event information 1a indicating what specific events can be recorded in the recording data 200a can be provided to the designer by the same system as the generation of the event information 1a based on the recording data 200a.

  Therefore, it is possible to drastically reduce the labor for generating the model of the event information 1a based on the recording data 200a. Further, since the event information 1a for a specific event that can actually occur can be provided to the operation personnel more reliably, the reliability of the information collection system 1 that generates the event information 1a based on the recording data 200a can be improved. .

  The event information for design includes, as supplementary information 2a, on-site data 100a of the data generation device 100 generated before or after the time when the change of the recording data 200a appears, or event information 1a based on the on-site data 100a. Also good.

  Thereby, it is possible to evaluate the change recorded in the recording data 200a in association with the on-site data 100a generated by the various data generators 100, and to determine the degree of necessity of the event information 1a for operation based on the recording data 200a. It becomes easy for the system designer to evaluate. For example, it can be evaluated whether it is sufficient to provide only the event information 1a based on the output of the sensor, or in addition, whether the provision of the event information 1a for operation based on the recording data 200a is beneficial.

  Specifically, the analysis engine 12 scans the recording data 200a with a standard pattern 131 that imitates the physical or clothing characteristics of the guard, and detects the arrival of the guard as the occurrence of a specific event. In the data generation device 100 such as a sensor, it is possible to easily provide the event information 1a that has been difficult to provide to the operation personnel.

  For example, the database 2 contains the actual arrival time of the security guard recorded in the recording data 200a, the estimated arrival time of the security guard, the late limit time, the late notice, and the arrival notice within the normal time. Each supplementary information 2a is stored. Then, based on the actual arrival time, the estimated arrival time of the guard, and the late limit time, one of the supplementary information 2a for the late notification or the normal time arrival notification can be selected and included in the event information 1a. Thereby, it becomes possible to evaluate the work attitude of the security guard only by browsing the event information 1a of arrival of the security guard, which is an advantage of the event information 1a based on the recording data 200a.

  In addition, the analysis engine 12 scans the recording data 200a with the standard pattern 131 that imitates the characteristics of the flame, and detects the fire as the occurrence of a specific event, so that the initial fire that is difficult for a fire alarm or the like to detect is detected. It is possible to provide event information 1a for more quickly informing the user.

  The database 2 stores the measured values of various sensors in the vicinity of the fire place as each supplementary information 2a, and includes the sensor measured values in the event information 1a in addition to the fire time and the fire place. Thereby, for example, it becomes easy to improve the fire detection method such as the position of the sensor, and to identify and take measures against the fire. For example, if there is event information 1a based on the recording data 200a when a fire breaks out from the conveyor, the location where the fire is likely to occur is identified, the location of the temperature sensor is reviewed based on the identification, the cause of the fire such as the conveyor transport speed, It becomes easy to review the conveyor speed.

  Further, the analysis engine 12 scans the recording data 200a with a standard pattern 131 that imitates the physical or clothing characteristics of the maintenance staff, and detects the arrival of the maintenance staff as the occurrence of a specific event. This is an advantage of the event information 1a based on the recording data 200a.

  The recorder 200 is installed with a screen of equipment such as a semiconductor manufacturing apparatus in view, and the analysis engine 12 is a standard pattern imitating a specific image, a specific character, a specific character string, a specific symbol, or a specific symbol string. In 131, the recording data 200a is scanned to detect the notification of the specific event of the equipment. Accordingly, event information 1a based on the observation result of the facility can be generated using the recorder 200 without constructing a mechanism for sending the field data 100a from the facility to the information collecting system 1, and the system of the factory or office Construction is easy and cost can be reduced.

  In addition, the analysis engine 12 scans the recording data 200a with each of the standard patterns 131 imitating human characteristics, detects changes in the human object specified by the standard patterns 131, and performs suspicious behavior including the fall of the patient. On-site data 100a indicating the occurrence of the event information 1a may be stored in the memory 11 to create a trigger for generating the event information 1a. This is an advantage of the event information based on the recording data 200a because it is possible to quickly know the suspicious behavior of the patient without having to attach a sensor for detecting the suspicious behavior to the patient or the like.
