  However, the above conventional configuration causes the following problems.

  First, in the first monitoring apparatus described above, it is necessary for the user to check all the captured contents and extract a problematic part. For this reason, this extraction operation alone requires a time longer than the photographing time. In addition, since all normal operations that occupy most of the shooting time are recorded, the amount of storage becomes enormous.

  Further, in the second monitoring device described above, since there is no work image of the worker, it is impossible to confirm what the work content of the worker was actually. Therefore, it is not possible to investigate specific problems in the work.

  Furthermore, the third monitoring device described above requires a large number of video cameras and an image processing device with excellent processing capability in order to accurately model moving images. Therefore, an increase in cost is inevitable.

  The present invention has been made in view of the above problems, and an object thereof is to provide a monitoring device capable of confirming repetitive work recorded in a short time with a simple configuration. .

  The monitoring device according to the present invention is a monitoring device that monitors repetitive work in order to solve the above-described problem, and when a predetermined number of repetitive work is defined as a unit work, a work start event and work for each unit work It is characterized by comprising detection means for detecting an end event, and event association means for associating the work start event and work end event of each unit work with the recorded data obtained by recording the repetitive work.

  According to the above configuration, when a predetermined number of repetitive operations are set as unit operations, the detection unit can detect the operation start event and the operation end event for each unit operation. The event association means associates the work start event and the work end event of each unit work with the recorded data obtained by recording the repetitive work. That is, the time point at which the work start event is detected is associated with the recorded data recorded at the time point, and the time point at which the work end event is detected is associated with the recorded data recorded at the time point. It is done.

  Therefore, it is possible to specify the recording data between the time when the work start event is detected and the time when the work end event is detected. Therefore, it is not necessary to confirm all the recording data of the repetitive work, and the repetitive work recorded in a short time can be confirmed.

  Further, based on the length information between the time point when the work start event is detected and the time point when the work end event is detected, the recording data having a predetermined length is specified from the specified recording data. It is also possible.

  Further, it is not necessary to model the moving image with high accuracy, and the monitoring device can have a simple configuration.

  Further, the monitoring device according to the present invention is the above monitoring device, wherein the work time calculating means for calculating the work time in each unit work from the occurrence time of the work start event and the occurrence time of the work end event, Determining means for determining whether or not each work time meets a predetermined condition, and recording corresponding to a unit work determined as not conforming to the condition from recorded data obtained by recording the repetitive work And an extraction means for extracting data.

  According to the above configuration, first, the work time in each unit work is calculated by the work time calculation means from the occurrence time of the work start event and the occurrence time of the work end event. In addition, it is determined by the determination means whether or not each work time meets a predetermined condition. Further, the extraction means extracts recorded data corresponding to the unit work determined not to meet the above conditions from the recorded data obtained by recording the repetitive work.

  Therefore, the user can confirm only the recorded data corresponding to the unit work that does not satisfy the above condition. Therefore, when the user sets the above conditions, there is an effect that only desired recording data can be confirmed.

  In the monitoring apparatus according to the present invention, in the monitoring apparatus, the determination unit determines whether each of the work times is equal to or greater than a first threshold and / or equal to or less than a second threshold. It is characterized by that.

  According to said structure, a determination means determines whether each work time is more than a 1st threshold value and / or below a 2nd threshold value, respectively.

  Here, when the work time exceeds the time required for the normal work to some extent, or when the work time is less than the time required for the normal work, there are many problems in the work itself.

  Therefore, there is an effect that it is possible to specify the image data in which the problematic work is recorded.

  In the monitoring device according to the present invention, in the monitoring device, a predetermined time zone immediately before the unit work is performed is a first time and a predetermined time immediately after the predetermined number of repetitive operations are performed. When the band is the second time, the extracting means extracts the recorded data including the first time and / or the second time.

  According to the above configuration, the extraction unit extracts the recording data including the recording data in the predetermined time zone immediately before the unit work is performed and / or the predetermined time zone immediately after the unit work.

  Therefore, the user can also check the state before the start of the unit work and / or the state after the end. For this reason, there is an effect that it can be confirmed even when the cause of the work in question is in the time zone before and / or after the end of the unit work. Furthermore, since a time width is given before and after the unit work, the repetitive work is not displayed suddenly when confirming the repetitive work in the unit work. Further, the display does not end immediately after the repetitive work is completed. Therefore, there is an effect that it is easy to confirm repetitive work.

  The monitoring apparatus according to the present invention is characterized in that in the above monitoring apparatus, the monitoring apparatus includes an erasing unit that erases recorded data other than the extracted recorded data from the recorded data obtained by recording the repetitive work.

  According to said structure, recording data other than the extracted recording data are erase | eliminated from the recording data which recorded the said repetitive work by an erasure | elimination means.

  Therefore, the data amount of the recording data in the device storing the recording data can be reduced. Therefore, the recording capacity of the device storing the recording data can be reduced.

  The monitoring device according to the present invention further comprises display control means for displaying on the display device the extracted recording data and the working time of the unit work extracted as the recording data. It is a feature.

  According to the above configuration, the display control unit displays the extracted recording data and the operation time of the unit work extracted as the recording data on the display device.

  Therefore, the user can check the operation time of the unit work extracted as the recorded data together with the extracted recorded data on the display device.

  Further, the monitoring device according to the present invention is the above monitoring device, wherein the display control means is identification information of a work object in each repetitive operation associated with the recording data, and is extracted as the recording data The identification information about the work object of the unit work thus performed is displayed on a display device.

  According to the above configuration, the display control means is the identification information of the work object in each repetitive work associated with the recording data, and the identification information about the work object of the unit work extracted as the recording data Is displayed on the display device.

  Therefore, the user can confirm the identification information of the work object together with the extracted recording data and the work time of the unit work extracted as the recording data on the display device.

  The monitoring device according to the present invention is characterized in that, in the above monitoring device, the recorded data obtained by recording the repetitive work is recorded data obtained by recording the repetitive work from a plurality of different directions.

  According to said structure, the user can confirm repetitive work from several different directions.

  Therefore, there is an effect that it becomes easy to analyze the work state in repetitive work.

  Moreover, the monitoring apparatus according to the present invention is characterized in that in the above-described monitoring apparatus, identification information association means for associating identification information of a work object in each repetitive operation with the recorded data is provided.

  According to said structure, the identification information correlation means associates the identification information of the work object in each repetitive work with the recording data.

  Therefore, the identification information of the work object can be specified together with the specification of the image data. Therefore, it is possible to specify the work object recorded in the specified image data based on the identification information.

  Further, based on the identification information, it is possible to specify the location of the recorded data in which the work object having the identification information is recorded.

  Moreover, the monitoring device according to the present invention is characterized in that, in the monitoring device, the predetermined number of times is one.

  According to the above configuration, the predetermined number of times is one.

  Therefore, image data can be specified for each repetitive operation. Therefore, it is possible to reduce the data amount of the specified image data (for example, extracted recording data).

  Further, for example, since it is possible to calculate the work time for each repetitive work, the calculated work time does not include the waiting time of the work object to be sent next. Therefore, even when the waiting time is not constant, it is not necessary to change the determination condition (that is, a predetermined condition) in the determination unit for each unit work. Therefore, image data can be extracted with a simple configuration.

  Further, in the monitoring apparatus according to the present invention, in the above monitoring apparatus, the recording data recording the repetitive work is recorded data recording the repetitive work for each type of repetitive work, and the detecting means includes the repetitive work. For each work type, a work start event and a work end event for each unit work are detected, and the event association unit is configured to record the repetitive work in accordance with the type of repetitive work. It is characterized by associating a work start event and a work end event of each unit work.

  According to said structure, the recording data which recorded the said repetitive work are the recording data which recorded the repetitive work for every kind of repetitive work. The detection means detects a work start event and a work end event for each unit work for each type of repetitive work. Further, the event association means associates the work start event and the work end event of each unit work according to the type of the repetitive work with the recorded data obtained by recording the repetitive work.

  Therefore, it is possible to monitor a plurality of repetitive work for each repetitive work with the monitoring device.

  The monitoring method according to the present invention is a monitoring method for monitoring repetitive work in order to solve the above-described problem. When a predetermined number of repetitive work is defined as a unit work, the work start event and work for each unit work are described. The method includes a first step of detecting an end event, and a second step of associating the work start event and the work end event of each unit work with the recorded data obtained by recording the repetitive work.

  According to the above method, when a predetermined number of repetitive tasks are set as unit tasks, the first step can detect a task start event and a task end event for each unit task.

  Further, in the second step, the work start event and the work end event of each unit work are associated with the recorded data obtained by recording the repetitive work. That is, the time point at which the work start event is detected is associated with the recorded data recorded at the time point, and the time point at which the work end event is detected is associated with the recorded data recorded at the time point. It is done.

  Therefore, it is possible to specify the recording data between the time when the work start event is detected and the time when the work end event is detected. Therefore, it is not necessary to confirm all the recording data of the repetitive work, and the repetitive work recorded in a short time can be confirmed.

  Further, based on the length information between the time point when the work start event is detected and the time point when the work end event is detected, the recording data having a predetermined length is specified from the specified recording data. It is also possible.

Furthermore, the work start time determination unit 13 and the time information addition unit 19 correspond to the identification information association unit described in the claims.

  FIG. 2 is a diagram for explaining a monitoring state of work when the monitoring device 1 is used. As shown in the figure, a product to be worked (work object) is a work process to be monitored by the monitoring device 1 from a previous work process (previous process) by a transfer device such as a belt conveyor (hereinafter, monitoring process). And a predetermined operation is performed in the monitoring step. And after the said predetermined | prescribed operation | work is given, a product is sent to the following operation | work process (post process) with a conveying apparatus (not shown). Thereafter, another similar product is sent from the previous work process to the monitoring process, and the same processing as described above is performed. As described above, in the present embodiment, the same kind of products are sequentially sent to the monitoring process, and at least in the monitoring process, the same work is repeatedly performed by the worker. That is, in the monitoring process, it is assumed that repetitive work (repetitive work) is performed by an operator.

  The first sensor 11 is installed near the entrance of the work place in the monitoring process. The second sensor 12 is installed near the exit of the work place. The photographing unit 18 is installed in a place where the work place and the work of the worker (work contents and work situation) can be photographed. In addition, the installation place of the 1st sensor 11 may be between the work place of a previous work process, and the work place of a monitoring process. Further, the installation location of the second sensor 12 may be between the monitoring process work place and the next work process work place.

  Hereinafter, each functional block in FIG. 1 will be described.

  The timer 10 generates a reference time in the monitoring device 1, and at least when the monitoring device 1 is in operation, this time information (hereinafter, time information) is used as the work start time determination unit 13, the work end time. The notification continues to the determination unit 14 and the time information addition unit 19.

  The first sensor 11 detects that the product has passed in front of the sensor (work start event). Further, when an identification number (identification information) such as a manufacturing number indicated by a barcode, an RFID tag or the like is attached to the product, the first sensor 11 receives the identification number by an identification number recognition unit 11a. recognize. Then, the first sensor 11 notifies the work start time determination unit 13 of a detection signal indicating detection and information on the identification number. In the following description, a case will be described in which an identification number is assigned to a product and the first sensor 11 recognizes the identification number.

  The second sensor 12 detects that the product has passed in front of the sensor (work end event). Then, the second sensor 12 notifies the work end time determination unit 14 of a detection signal indicating that it has been detected.

  The work start time determination unit 13 continues to receive time information from the timer 10 in real time. In addition, when the work start time determination unit 13 receives a detection signal from the first sensor 11, the work start time determination unit 13 determines the time when the detection signal is received based on the time information. The determined time is notified to the work time calculation unit 15 and the writing / reading unit 16 as the work start time. In addition, the work start time determination unit 13 notifies the writing / reading unit 16 of the identification number information in association with the work start time.

  The work end time determination unit 14 continues to receive time information from the timer 10 in real time. In addition, when receiving the detection signal from the second sensor 12, the work end time determination unit 14 determines the time at which the detection signal is received based on the time information. The determined time is notified to the work time calculation unit 15 and the writing / reading unit 16 as the work end time.

  The work time calculation unit 15 receives the work start time from the work start time determination unit 13 and the work end time from the work end time determination unit 14. Then, the work time calculation unit 15 calculates the work time by subtracting the work start time from the work end time. Furthermore, the work time calculation unit 15 notifies the writing / reading unit 16 of the calculated work time.

  The writing / reading unit 16 receives work start time and identification number information from the work start time determination unit 13, work end time from the work end time determination unit 14, and work time from the work time calculation unit 15. Then, the writing / reading unit 16 associates the work start time, the work end time, and the work time with the identification number, and uses the associated information as work history information. Information is stored in the work history storage unit 17.

  The monitoring apparatus 1 creates the work history information for each product sequentially sent from the previous work process, and stores the work history information in the work history storage unit 17. As a result, the work history storage unit 17 stores information associated with each product (identification information) as shown in FIG.

  The photographing unit 18 continuously photographs the work place and the work of the worker as a moving image. And the imaging | photography part 18 transmits this imaged image data with respect to the time information addition part 19 in real time as shown in FIG.

  The time information adding unit 19 continues to receive the time information from the timer 10 in real time. The time information adding unit 19 adds the time information to the image data sent from the photographing unit 18. That is, the time indicated by the time information is added to the image data. Thereby, the time is associated with each image (part of the continuous image) constituting the moving image. Further, the time information adding unit 19 sends the image data to which the time information is added to the writing / reading unit 20.

  The writing / reading unit 20 causes the image data storage unit 21 to store the image data to which the time information from the time information adding unit 19 is added. As a result, the image data storage unit 21 stores the image data to which the time information is added. The image data stored in the image data storage unit 21 is also referred to as recording data.

  The operation unit 22 sends a predetermined command signal based on an instruction from the user to the determination unit 23 and the display control unit 28. In the following description, the operation of the monitoring device 1 when the monitoring of the work by the monitoring device 1 is temporarily stopped and the user confirms the work content of the worker will be described.

  When receiving a predetermined command signal from the operation unit 22, the determination unit 23 performs the following operation. First, the determination unit 23 instructs the writing / reading unit 16 to read work history information from the work history storage unit 17 and to transmit the read work history information to the determination unit 23. When the determination unit 23 acquires the work history information, the determination unit 23 determines whether each work time in the work history information satisfies a predetermined condition. More specifically, the condition that the work time is not less than the first predetermined time (first threshold) W1 and not more than the second predetermined time (second threshold) W2 is satisfied. Determine whether or not.

  Then, the determination unit 23 transmits some information in the work history information related to the work time determined as not satisfying the predetermined condition to the image data extraction unit 24. That is, the determination unit 23 displays information about the work start time, the work end time, and the work time corresponding to a certain identification number (for example, the product of the identification information i shown in FIG. 3) as information on the identification number. At the same time, it is transmitted to the image data extraction unit 24. If there are a plurality of work times that are determined not to satisfy the predetermined condition, some information in the work history information related to the plurality of work times is transmitted to the image data extraction unit 24. Hereinafter, part of the information in the work history information is referred to as work history partial information.

  The image data extraction unit 24 receives the work history partial information from the determination unit 23. Further, the image data extraction unit 24 sends the image data between the work start time and the work end time in the work history partial information to the writing / reading unit 20, a predetermined time immediately before the work start time (hereinafter referred to as “working start time”). The image data of the first time Wa) and the image data of a predetermined time (hereinafter referred to as the second time Wb) immediately after the work end time are instructed to be read from the image data storage unit 21. As a result, the image data is extracted including the image data at the first time Wa and the second time Wb.

  When the writing / reading unit 20 receives the instruction from the image data extracting unit 24, the writing / reading unit 20 reads the image data corresponding to the instruction from the image data storage unit 21 and sends the read image data to the image data extracting unit 24. The image data is read based on time information added to the image data.

  When the image data extracting unit 24 extracts the image data corresponding to the instruction from the writing / reading unit 20, the image data extracting unit 24 performs the following operation. First, the image data extraction unit 24 associates the image data, the identification number information, the work start time, the work end time, and the work time with each other to the writing / reading unit 25, and the extracted data storage unit 26. Remember me. When there are a plurality of operations determined not to meet the predetermined condition, the extracted data storage unit 26 stores a plurality of sets of data associated with each other for each image data.

  The image data extracting unit 24 sends a predetermined signal to the image data erasing unit 27 after completing the extraction of the image data from the image data storage unit 21.

  When receiving the predetermined signal from the image data extracting unit 24, the image data erasing unit 27 sends an instruction for erasing the image data stored in the image data storage unit 21 to the writing / reading unit 20. Upon receiving this instruction, the writing / reading unit 20 erases all image data from the image data storage unit 21. At this time, the time information added to the image data is also deleted.

  Thereby, only the extracted image data is memorize | stored in the monitoring apparatus 1 regarding image data.

  When the display control unit 28 receives a predetermined command signal from the operation unit 22, the display control unit 28 reads out the associated data stored in the extracted data storage unit 26 from the writing / reading unit 25, and the display control unit The transmission of the read data to 28 is instructed. Then, the display control unit 28 causes the display unit 29 to display the read data. The display method on the display unit 29 by the display control unit 28 may be any method.

  For example, the image data may be displayed in the oldest order (or newest order) of the work start time, and the identification number information and the work time may be displayed on the display unit 29 as shown in FIG. Here, when the image data and the work time are displayed, the user can confirm the work time of the repetitive work extracted as the image data together with the extracted image data on the display unit 29. Further, when the image data, the work time, and the identification number information are displayed, the identification number of the product that is the work object of the repetitive work can also be confirmed.

  Further, not only the identification number information and the work time, but also the work start time and work end time may be displayed. Information to be displayed other than the image data is not particularly limited. In addition, it is preferable that which information other than the image data is displayed on the display unit 29 can be changed by a signal from the operation unit.

  The display unit 29 can be configured by, for example, a liquid crystal display or a CRT (Cathode Ray Tube). The display unit 29 may be a touch panel type, and the operation unit 22 and the display unit 29 may be configured integrally.

  As described above, in the monitoring device 1, the first sensor 11 detects a work start event, and the second sensor 12 detects a work end event. Further, in the monitoring device 1, the work start time determination unit 13 and the work end time determination unit 14 respectively perform a work start time (that is, a work start event occurrence time) and a work end time (that is, a work end event occurrence time). Is stored in the work history storage unit 17 and the time information adding unit 19 adds time information to the captured image data, so that the operation is performed on the image data (recorded data) recorded by the recording unit 3. A start event and a work end event are associated.

  In the above description, the single photographing unit 18 is provided. However, the present invention is not limited to this. It is good also as a structure which provides a some imaging | photography part and image | photographs a work place and an operator's work from a mutually different direction. In this case, a plurality of pieces of image data can be confirmed on the display unit 29 for work in the same time zone. For this reason, it becomes easy to analyze the work state in repetitive work. In this case, as shown in FIG. 5, the display unit 29 divides the display area of the display unit 29 into a plurality of areas (four in the figure), and simultaneously checks a plurality of image data. It is preferable to have a configuration that can be used. With this configuration, it is possible to analyze the working state with higher accuracy.

  In the above description, for convenience of explanation, the configuration in which the writing / reading unit 16, the writing / reading unit 20, and the writing / reading unit 25 are provided separately is shown. It is good also as a structure which put together (16 * 20 * 25) into one. Moreover, although the structure which provided the work history memory | storage part 17, the image data memory | storage part 21, and the extraction data memory | storage part 26 separately was shown, it is good also as a structure which put these together.

  In the above description, as described above, the predetermined condition includes a condition that the work time is not less than the first predetermined time W1 and not more than the second predetermined time W2. It was. However, the present invention is not limited to this. For example, whether the work time is equal to or shorter than the second predetermined time W2 may be set as the predetermined condition, or the work time may be equal to or longer than the first predetermined time W1. It is good also as said predetermined condition.

  However, it is preferable that the predetermined condition is set such that the work time is equal to or longer than the first predetermined time W1 and the work time is equal to or shorter than the second predetermined time W2. In other words, if the work time exceeds the time required for the normal work to some extent, or if the work time is less than the time required for the normal work to some extent, the work itself often has some problem. Therefore, in the above configuration, it is possible to extract image data that records such problematic work.

  In the above description, the work time is calculated for one product, and the image data is extracted based on the calculated work time. However, the present invention is not limited to this. You can also.

  That is, instead of calculating the work time for one product, the work time for a plurality of products is calculated. That is, the work time calculation unit 15 is configured to calculate work times for a plurality of products. Specifically, when the plurality of products are n products, the work time for n products is calculated from the work start time for the first product and the work end time for the nth product. To do.

  Also with this configuration, for example, when the work time for the i-th product is long (or short), the work time for the n products is also long (or short). It can be determined that it is not satisfied (1 ≦ i ≦ n).

  In this case, since the work time for a plurality of products is regarded as one work time, the amount of data stored in the work history storage unit 17 can be reduced. As a result, the number of image data extractions can be reduced.

  As described above, the monitoring device is a monitoring device that monitors repetitive work. When the predetermined number of repetitive work is defined as a unit work, the first monitoring device detects a work start event and a work end event for each unit work. And a second sensor (detection means) (11, 12) and a work start time determination unit 13 for associating a work start event and a work end event of each unit work with the recorded data recording the repetitive work, The operation end time determination unit 14 and a time information addition unit 19 (event association unit) (hereinafter referred to as an event association unit) are provided.

  According to this configuration, when a predetermined number of repetitive tasks are set as unit tasks, the first sensor 11 and the second sensor 12 can detect a task start event and a task end event for each unit task. Further, the event association unit associates the work start event and the work end event of each unit work with the recorded data obtained by recording the repetitive work. That is, the time point at which the work start event is detected is associated with the recorded data recorded at the time point, and the time point at which the work end event is detected is associated with the recorded data recorded at the time point. It is done.

  Therefore, it is possible to specify the recording data between the time when the work start event is detected and the time when the work end event is detected. Therefore, it is not necessary to confirm all the recording data of the repetitive work, and the repetitive work recorded in a short time can be confirmed.

  Further, based on the length information between the time point when the work start event is detected and the time point when the work end event is detected, the recording data having a predetermined length is specified from the specified recording data. It is also possible.

  The monitoring device 1 further includes a work time calculation unit (work time calculation means) 15 that calculates a work time in each unit work from the occurrence time of the work start event and the occurrence time of the work end event, A unit that is determined not to conform to the conditions from the determination unit (determination means) 23 that determines whether or not each work time conforms to a predetermined condition and recorded data that records the repetitive work The image data extracting unit (extracting means) 24 that extracts the recording data corresponding to the work is also provided.

  According to this configuration, first, the work time calculation unit 15 calculates the work time in each unit work from the time when the work start event occurs and the time when the work end event occurs. Further, the determination unit 23 determines whether each work time meets a predetermined condition. Further, the image data extraction unit 24 extracts recorded data corresponding to the unit work determined not to meet the above conditions from the recorded data obtained by recording the repetitive work.

  Therefore, the user can confirm only the recorded data corresponding to the unit work that does not satisfy the above condition. Therefore, if the user sets the above conditions, only desired recording data can be confirmed.

  Further, the predetermined number of repetitive operations are preferably one repetitive operation. According to this configuration, image data can be extracted for each repetitive operation. Therefore, it is possible to reduce the data amount of the extracted recording data.

  Further, since the work time can be calculated for each repetitive work, the calculated work time does not include the waiting time of the work object to be sent next. Therefore, even when the waiting time is not constant, it is not necessary to change the determination condition in the determination unit 23 for each unit work. Therefore, image data can be extracted with a simple configuration.

  By the way, in the above description, the configuration in which the monitoring device 1 monitors one work process has been described. Hereinafter, an application example of the monitoring device 1 that monitors a plurality of work processes using the monitoring device 1 will be described.

  First, as shown in FIGS. 6 and 7, the monitoring device is provided with as many sensor pairs as the first sensor 11 and the second sensor 12 as the number of work steps to be monitored. Here, as in the case shown in FIG. 1, the first sensor 11 constituting each sensor pair gives the work start time determination unit 13 a detection signal indicating that a product has been detected as described above. And the serial number information are sent (see FIG. 7). In addition, the second sensor 12 constituting each sensor pair sends a detection signal indicating that the product has been detected to the work end time determination unit 14.

  In this case, the work start time determination unit 13 is configured to determine the work start time for each work process, and the work end time determination unit 14 is configured to determine the work end time for each work process. In addition, the work time calculation unit 15 is configured to calculate the work time for each work process. With this configuration, the work history storage unit 17 stores work history information for each work process as shown in FIG.

  Further, the photographing unit 18 is provided in the monitoring device so as to correspond to each work process by the number of work processes, and each photographing unit 18 is configured to photograph the work place and worker's work related to each work process. In addition, the time information adding unit 19 is configured to accept image data captured by each imaging unit and add time information to the image data from each imaging unit 18. With this configuration, the image data storage unit 21 stores image data for each work process.

  And the determination part 23 is made to perform the determination mentioned above about all the work processes. Further, the image data extraction unit 24 extracts image data for each work process from the image data storage unit 21 via the writing / reading unit 20, and the extracted image data is transmitted via the writing / reading unit 25. The extracted data storage unit 26 is configured to store the data.

  By providing the above configuration in the monitoring device, it is possible to monitor a plurality of work processes with a single monitoring device.

  In this case, the method of displaying the extracted image data and the like on the display unit 29 is, for example, in the order of the work process (that is, after the extracted image data related to the nth work process is displayed, the (n + 1) th work process. The extracted image data may be displayed), or the extracted data in the previous work process may be displayed in order from the work start time in order, and the display method is not particularly limited Absent. However, it is more convenient to confirm (analyze) the work contents because the work is displayed in the order of the work processes because the work in one work process can be confirmed continuously. In addition, it is preferable that the display method on the display unit 29 can be changed within the range of the display method set in advance by a command from the operation unit 22.

  Further, when a plurality of sensor pairs are provided as described above and a plurality of work processes are monitored, a predetermined condition serving as a determination condition in the determination unit 23 is set for each work process. With such a configuration, even if the work time considered necessary for the work is different in each work process, it is possible to cope with one monitoring device.

  When a plurality of sensor pairs and imaging units 18 are provided, as described above, the work start time determination unit 13, the work end time determination unit 14, the work time calculation unit 15, the determination unit 23, the image data extraction unit 24, The time information adding unit 19 or the like is configured to perform processing for each work process. That is, the work start time determination unit 13, the work end time determination unit 14, the work time calculation unit 15, the determination unit 23, the image data extraction unit 24, the time information addition unit 19, and the like have a processing function corresponding to each work process. It can be said that.

  As described above, when a plurality of sensor pairs and photographing units 18 are provided, the monitoring device may be configured such that the recording data recording the repetitive work is recorded data recording the repetitive work for each type of repetitive work. The first and second sensors (detection means) (11, 12) detect a work start event and a work end event for each unit work for each type of repetitive work, and the event association unit performs the repetitive work. It can be said that the recording start data and the work end event of each unit work are associated with the recorded video data according to the type of repetitive work.

  According to this configuration, the recording data in which the repetitive work is recorded is recorded data in which the repetitive work is recorded for each type of repetitive work. The first and second sensors (11, 12) detect a work start event and a work end event for each unit work for each type of repetitive work. Further, the event association unit associates the work start event and the work end event of each unit work according to the type of the repetitive work with the recorded data obtained by recording the repetitive work.

  Therefore, the monitoring device can monitor a plurality of repetitive operations for each repetitive operation.

  The monitoring device 1 is also configured to include a work start time determination unit 13 and a time information addition unit 19 (identification information association unit) that associates identification information of a work object in each repetitive work with recorded data. .

  According to this configuration, the work start time determination unit 13 and the time information addition unit 19 associate the identification information of the work object in each repetitive work with the recorded data.

  Therefore, the identification information of the work object can be specified together with the specification of the image data. Therefore, it is possible to specify the work object recorded in the specified image data based on the identification information.

  Further, based on the identification information, it is possible to specify the location of the recorded data in which the work object having the identification information is recorded.

  Further, as described above, the image data is extracted including the image data at the first time Wa and the second time Wb. That is, assuming that the predetermined time zone immediately before the unit work is performed is the first time and the predetermined time zone immediately after the predetermined number of repetitive work is the second time, the image data extracting unit 24. Are extracted including the recording data at the first time and / or the second time.

  According to this configuration, the image data extraction unit 24 extracts recorded data including recorded data of a predetermined time zone immediately before the unit work is performed and a predetermined time zone immediately after the unit work.

  Therefore, the user can also check the state before the start of the unit work and / or the state after the end. Furthermore, since a time width is given before and after the unit work, the repetitive work is not displayed suddenly when confirming the repetitive work in the unit work. Further, the display does not end immediately after the repetitive work is completed. Therefore, it becomes easy to confirm repetitive work.

  Further, as described above, the image data erasure unit 27 erases the recording data other than the extracted recording data from the recording data recorded by the recording unit 3. Therefore, the data amount of the recording data in the recording unit 3 can be reduced. Therefore, the storage capacity of the image data storage unit 21 of the recording unit 3 can be reduced.

  Here, FIG. 9A shows a time chart regarding the detection signal of the sensor in the configuration shown in FIG. 6 and FIG. FIG. 9B shows a work time zone for each product in each work process determined from the detection signal. Further, FIG. 9C shows image data extracted from the image data storage unit 21. 9 (b) and 9 (c), for convenience of explanation, numbers are assigned to products according to the order of processing, and they are shown as product 1, product 2, product 3,..., Product 9. Yes.

  In FIG. 9B, the work time for the product 3 in the work process 2 is longer than the work time of other products in the work process. Further, the work time for the product 5 in the work process 3 is shorter than the work time of other products in the work process.

  When the determination unit 23 determines that the work time of the product 3 in the work process 2 and the work time of the product 5 in the work process 3 do not satisfy the predetermined condition, the image data regarding the work of the product 3 and Image data relating to the work of the product 5 is extracted from the image data storage unit 21 by the image data extraction unit 24 (see FIG. 9C). FIG. 9C shows a state in which image data is extracted including the first time Wa and the second predetermined Wb (that is, the front and back margin times).

  As described above, only image data that does not satisfy the predetermined condition is extracted from the image data storage unit 21 and stored in the extracted data storage unit 26.

  Further, when a plurality of sensor pairs and imaging units 18 are provided as described above, the following configuration may be employed. That is, as shown in FIG. 10, adjacent work processes may share the sensor. Specifically, when the monitoring device monitors n work processes, for example, n + 1 first sensors 11 are prepared, and the work start time and work end time are determined between adjacent sensors. Good. With this configuration, the number of sensors in the monitoring device can be reduced. The figure shows a configuration in which there are three work processes, and the monitoring device includes four sensors and three photographing units.

  Next, a setting flow at the time of initial setting of the monitoring device 1 will be described with reference to FIG. A case where one work process is monitored will be described.

  First, the first sensor 11, the second sensor 12, and the photographing unit 18 are arranged at predetermined positions (S1). After S1, predetermined conditions as image data extraction conditions are set (S2). Specifically, the first predetermined time W1 (first threshold value), the second predetermined time W2 (second threshold value), the predetermined time immediately before the work start time (first time Wa), and the work end A predetermined time (second time Wb) immediately after the time is set.

  After S2, a test operation is performed (S3). After S3, it is determined whether proper monitoring is performed (S4). This determination is made by the user. If it is determined in S4 that proper monitoring is being performed, the process ends. On the other hand, if it is determined in S4 that proper monitoring is not performed, the process returns to S1.

  In addition, although FIG. 11 demonstrated the case where one work process was monitored, when monitoring several work processes, the process of S1 to S4 should just be performed for every work process.

  Next, the flow at the time of monitoring by the monitoring device 1 will be described based on FIGS. A case where one work process is monitored will be described. Further, a case will be described in which the work time is calculated for each product and it is determined whether or not the work time satisfies a predetermined condition.

  FIG. 12 is a flowchart showing a flow up to a process of writing work history information to the work history storage unit 17. First, as shown in the figure, the work start time determination unit 13 determines the work start time (S11). After S11, the work end time is determined by the work end time determination unit 14 (S12). After S12, the work time calculation unit 15 calculates the work time for each product from the work start time and the work end time (S13). After S13, the writing / reading unit 16 stores information on the work start time, work end time, and work time in the work history storage unit 17 in association with the identification number (S14).

  FIG. 13 is a flowchart showing the flow up to the image data storage process in the image data storage unit 21. First, as shown in the figure, the work area and the work of the worker are photographed by the photographing unit 18 (S21). After S21, the time information adding unit 19 adds the time information to the image data photographed by the photographing unit 18 in real time (S22). After S22, the image data to which the time information is added is stored in the image data storage unit 21 by the writing / reading unit 20 (S23).

  FIG. 14 is a flowchart showing a processing flow at the time of image data extraction. First, as shown in the figure, the determination unit 23 determines whether or not the work time for each product satisfies a predetermined condition based on the work history information stored in the work history storage unit 17 (S31). . In S31, when the working time for each product satisfies a predetermined condition, the process is terminated. On the other hand, when it is determined in S31 that there is a work time that does not satisfy the predetermined condition, the image data extraction unit 24 extracts image data related to the work time from the image data storage unit 21 (S32). . After S32, the image data extraction unit 24 stores the extracted image data in the extraction data storage unit 26 (S33). After S33, the display control unit 28 reads the image data stored in the extracted data storage unit 26 via the writing / reading unit 25, and sequentially displays the image data on the display unit 29 (S34). Thus, a series of processing ends.

  Further, in the present embodiment, the determination unit 23 is configured to read the work end time information from the work history storage unit 17 by the determination unit 23. However, for example, without reading the work end time information, The determination unit 23 may add the work time to the work start time to calculate the work end time, and send the calculated work end time to the image data extraction unit 24. In this case, the work history storage unit 17 does not necessarily need to store the work end time, and the storage capacity of the work history storage unit 17 can be set small. Alternatively, the determination unit 23 may calculate the work start time by subtracting the work time from the work end time without reading the work start time information.

  Moreover, in this Embodiment, although it is the structure which provided one timer 10 in the monitoring apparatus 1, the structure which provided the timer in each of the work time detection part 2 and the video recording part 3, and synchronizes the time which both timers show It may be.

  By the way, in the above description, the case where the identification number is given to the product and the identification number is recognized by the identification number recognition unit 11a has been described. However, the identification number (identification information) is given to the product. If not, the writing / reading unit 16 associates the work start time, the work end time, and the work time with each other, and additionally attaches a number for identification to the associated information to obtain work history information. Then, the work history information may be stored in the work history storage unit 17.

  The recording unit 3 can be configured using, for example, a video camera device. In this case, the photographing unit 18 functions as a camera unit and an image processing unit, and the image data storage unit 21 functions as a storage medium such as a video tape or a hard disk.

  The extraction of the image data from the image data storage unit 21 does not necessarily include the first time Wa and the second time Wb.

  In the above description, the image data extraction unit 24 is provided, predetermined image data is extracted from the image data storage unit 21, and the extracted image data is stored in the extraction data storage unit 26. However, when the image data storage unit 21 and the extraction data storage unit 26 are configured by a single storage medium, the extraction process in the image data extraction unit 24 is simply performed by the above-described storage medium. An address designation process for predetermined image data may be performed. It suffices that the image data extraction unit 24 can specify a predetermined image in the monitoring device 1.

  The monitoring device is a monitoring device for monitoring repetitive work, the recording unit 3 for recording the repetitive work, the work time detecting unit 2 for repeatedly detecting work time required for a predetermined number of repetitive work, Each of the detected work times conforms to the above condition from the determination unit (determination means) 23 for determining whether or not the predetermined time satisfies a predetermined condition, and the repetitive work recording data recorded by the recording unit 3 It can also be said that the image data extracting unit (extracting means) 24 for extracting recording data corresponding to a predetermined number of repetitive operations determined not to be performed is provided.

  In the above description, the monitoring device including the photographing unit 18, the writing / reading unit 20, and the image data storage unit 21 has been described. However, the monitoring device is not necessarily provided with the photographing unit 18, the writing / reading unit. 20 and the image data storage unit 21 need not be provided. For example, the photographing unit 18, the writing / reading unit 20, and the image data storage unit 21 are provided in another device (for example, a video camera), and the video camera is connected to a monitoring device that does not include the photographing unit 18 and the like. It is good also as a structure.

  Furthermore, a timer built in the video camera or the like can be used as the timer 10. In this case, the timer 10 and the time information adding unit 19 are no longer essential components of the monitoring device. In this case, a timer built in the video camera or the like may be configured to transmit time information to the work start time determination unit 13 and the work end time determination unit 14.

  Also, the work history storage unit 17, the extracted data storage unit 26, and the display unit 29 may be configured as devices that are separate from the monitoring device and can be connected to the monitoring device.

[Embodiment 2]
Another embodiment of the present invention will be described below with reference to FIGS. 15 and 16. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and descriptions thereof are omitted. The various feature points described in the first embodiment can be applied in combination with the present embodiment.

  Also in the present embodiment, a monitoring device configured to monitor one work process will be described as in the first embodiment.

  FIG. 15 is a functional block diagram of the monitoring apparatus according to the embodiment of the present invention. As shown in the figure, the monitoring device 1 'includes a timer 10, a first sensor 11, a second sensor 12, a work start time determination unit 13', a work end time determination unit 14 ', a work time calculation unit (work time (Calculating means) 15 ', photographing section 18, time information adding section 19, writing / reading section 20, image data storage section 21, operating section 22, determination section (determination section) 23', image data extraction section (extraction section) 24 ', a writing / reading unit 25, an extracted data storage unit 26, an image data erasing unit (erasing means) 27', a display control unit 28, and a display unit 29.

  That is, compared with the monitoring device 1 of the first embodiment, the monitoring device 1 ′ does not include the writing / reading unit 16 and the work history storage unit 17, the work start time determination unit 13, and the work end time determination unit. 14, work time calculation unit 15, determination unit 23, image data extraction unit 24, and image data deletion unit 27, work start time determination unit 13 ′, work end time determination unit 14 ′, work time calculation unit 15 ′, The monitoring device 1 is different from the monitoring device 1 in that a determination unit 23 ′, an image data extraction unit 24 ′, and an image data deletion unit 27 ′ are provided.

  Hereinafter, the first sensor 11, the second sensor 12, the work start time determination unit 13 ′, the work end time determination unit 14 ′, and the work time calculation unit 15 ′ are combined, and the work time detection unit 2 ′.

  Furthermore, the work start time determination unit 13 ′, the work end time determination unit 14 ′, and the time information addition unit 19 correspond to the event association unit described in the claims. Furthermore, the work start time determination unit 13 ′ and the time information addition unit 19 correspond to the identification information association unit described in the claims.

  Below, the block different from the monitoring apparatus 1 is demonstrated.

  The work start time determination unit 13 ′ continues to receive time information from the timer 10 in real time. In addition, when the work start time determination unit 13 receives a detection signal from the first sensor 11, the work start time determination unit 13 determines the time when the detection signal is received based on the time information. The determined time is notified to the work time calculation unit 15 ′ as the work start time.

  Further, the work start time determination unit 13 ′ notifies the work time calculation unit 15 ′ in association with the product identification number information and the work start time.

  The work end time determination unit 14 ′ continues to receive time information from the timer 10 in real time. Further, when receiving the detection signal from the second sensor 12, the work end time determination unit 14 ′ determines the time when the detection signal is received based on the time information. The determined time is notified to the work time calculation unit 15 ′ as the work end time.

  The work time calculation unit 15 ′ receives the work start time and identification number information from the work start time determination unit 13 ′ and the work end time from the work end time determination unit 14 ′. Then, the work time calculation unit 15 ′ calculates the work time by subtracting the work start time from the work end time. Further, the work time calculation unit 15 ′ associates the work start time, work end time, and work time with the identification number, and uses the association information as work history information, and sequentially determines The work history information is sent to the unit 23 '.

  The determination unit 23 ′ determines whether the work time in the work history information satisfies a predetermined condition based on the work history information sequentially sent from the work time calculation unit 15 ′. More specifically, the condition that the work time is not less than the first predetermined time (first threshold) W1 and not more than the second predetermined time (second threshold) W2 is satisfied. Determine whether or not. Then, the determination unit 23 ′ transmits work history information related to the work time determined as not satisfying the predetermined condition to the image data extraction unit 24 ′.

  The image data extraction unit 24 ′ sequentially receives the work history information from the determination unit 23 ′. Further, the image data extraction unit 24 ′ gives the writing / reading unit 20 image data between the work start time and the work end time in the work history information, the image data of the first time Wa, And it instructs to read out the image data of the second time Wb from the image data storage unit 21. As a result, the image data is extracted including the image data at the first time Wa and the second time Wb.

  Further, when image data corresponding to the above instruction is acquired (extracted) from the image data extraction unit 24 ′ and the writing / reading unit 20, the following operation is executed. First, the image data extraction unit 24 ′ associates the image data, the identification number information, the work start time, the work end time, and the work time with the writing / reading unit 25, and extracts the data storage unit. 26 is stored. Further, after extracting the image data from the image data storage unit 21, the image data extraction unit 24 'sends a predetermined signal to the image data erasing unit 27'.

  Upon receipt of the predetermined signal from the image data extraction unit 24 ′, the image data erasing unit 27 ′ is image data stored in the image data storage unit 21 with respect to the writing / reading unit 20, and An instruction to delete the image data up to the work end time (or a time before the work end time) related to the extracted image data is sent. Upon receiving this instruction, the writing / reading unit 20 erases the above-described image data from the image data storage unit 21. At this time, the time information added to the image data is also deleted.

  As a result, only the extracted image data is stored in the monitoring device 1 ′ with respect to the image data. Furthermore, since the image data erasing unit 27 ′ sequentially erases the image data stored in the image data storage unit 21, the storage capacity of the image data storage unit 21 can be reduced.

  As described above, the monitoring device 1 ′ according to the present embodiment is a monitoring device that monitors repetitive work. When a predetermined number of repetitive work is a unit work, the work start event and work for each unit work are described. Work for associating the work start event and work end event of each unit work with the first and second sensors (detection means) (11, 12) for detecting the end event and the recorded data recording the repetitive work The configuration includes a start time determination unit 13 ′, a work end time determination unit 14 ′, and a time information addition unit 19 (event association unit). With this configuration, the same effect as that of the monitoring device 1 of the first embodiment can be obtained.

  Further, the monitoring device 1 ′ does not require the work history storage unit 17 shown in the first embodiment, and the storage capacity of the image data storage unit 21 can be reduced, which is advantageous in terms of cost.

  Note that the image data erasing unit 27 ′ may be configured to erase image data in a lump later, for example, in accordance with an instruction from the operation unit 22, without being configured to sequentially erase image data.

  Similarly to the first embodiment, the monitoring device 1 ′ may be configured to calculate the work time for a plurality of products instead of calculating the work time for one product. With this configuration, the same effect as in the first embodiment can be obtained.

  Further, like the monitoring device 1 of the first embodiment, the monitoring device 1 ′ may be applied to a configuration for monitoring a plurality of work processes. Also in this case, the same effect as in the first embodiment can be obtained.

  Next, the flow at the time of monitoring by the monitoring device 1 ′ will be described based on FIG. A case where one work process is monitored will be described. Further, a case will be described in which the work time is calculated for each product and it is determined whether or not the work time satisfies a predetermined condition.

  First, as shown in the figure, the work start time determination unit 13 'determines the work start time (S41). After S41, the work end time is determined by the work end time determination unit 14 '(S42). After S42, the work time calculation unit 15 'calculates the work time for each product from the work start time and the work end time (S43). After S13, the determination unit 23 'determines whether or not each calculated work time satisfies a predetermined condition (S44).

  If the predetermined condition is satisfied in S44, the process is terminated. On the other hand, if there is a work time that does not satisfy the predetermined condition in S44, the image data extraction unit 24 'sequentially extracts image data relating to the work time from the image data storage unit 21' (S45). After S45, the image data extraction unit 24 'stores the sequentially extracted image data in the extraction data storage unit 26 (S46). After S46, the display control unit 28 reads out the image data stored in the extracted data storage unit 26 via the writing / reading unit 25 and sequentially displays it on the display unit 29 (S47). Thus, a series of processing ends.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.

  In addition, each part and each processing step of the monitoring device of the above-described embodiment are such that a calculation unit such as a CPU executes a program stored in a storage unit such as a ROM (Read Only Memory) or a RAM, an input unit such as a keyboard, It can be realized by controlling output means such as a display or communication means such as an interface circuit. Therefore, the computer having these means can realize various functions and various processes of the monitoring apparatus of the present embodiment simply by reading the recording medium storing the program and executing the program. In addition, by recording the program on a removable recording medium, the various functions and various processes described above can be realized on an arbitrary computer.

  As this recording medium, a program medium such as a memory (not shown) such as a ROM may be used for processing by the microcomputer, or a program reader is provided as an external storage device (not shown). It may be a program medium that can be read by inserting a recording medium therein.

  In any case, the stored program is preferably configured to be accessed and executed by the microprocessor. Furthermore, it is preferable that the program is read out, and the read program is downloaded to a program storage area of the microcomputer and the program is executed. It is assumed that this download program is stored in advance in the main unit.
