  The monitoring target of the monitoring server 101 is the rolling plant 135. Here, the rolling plant 135 gradually reduces the thickness of the steel plate 141 by applying a rolling force at the four stands of the first stand 146, the second stand 147, the third stand 148, and the fourth stand 149. In the steel plate 141 1, the rear steel plate is connected at the welding point 144 and the front steel plate is connected at the welding point 145, and so-called continuous rolling is performed.

  The monitoring terminal 151 is connected to the network 157 and monitors and displays the state of the rolling plant 135 on the monitor screen 152 of the display device. A GW (gateway) 156 connected to the network 157 on the remote site 150 side is connected to the monitoring terminal 151. It is connected to the network 133 via a public network 170 and a GW (gateway) 132 on the factory 100 side, and signals can be exchanged with the monitoring server 101 by such a connection configuration.

  The monitoring terminal 151 includes a data acquisition unit 153 that transmits a request information signal to the monitoring server 101 for data requested by the user from the monitoring screen 152, and acquires data obtained correspondingly.

The time giving means 107 is periodically activated by a timer. In an actual system, it is often started in about 20 ms to 100 ms according to the required time accuracy.

  In the operation process of the time giving means 107, it is first determined whether or not the coil welding points 144 and 145 have passed the process data detection position for one of the process data (step S201).

  As a result of this determination, if the welding points 144 and 145 pass through the detection positions, the time that the monitoring server 101 has is taken in, and the time for removing the front coil and the time for entering the rear coil are specified (step S202). After the data is output to the process data storage means 104, it is determined whether or not the process has been completed for all the process data (step S203). If the welding points 144 and 145 do not pass the detection position, the process jumps. Then, it is determined whether or not the process has been completed for all process data (step S203).

  Next, as a result of this determination, if the processing is not completed for all the process data, before determining whether or not the welding points 144 and 145 of the initial processing coil have passed the detection position of the process data (step S201). To return to the next process data and repeat each process, but if the process is completed for all the process data, whether or not the coil welding points 144 and 145 have passed the camera imaging position. A determination is made (step S204). Here, when there are a plurality of cameras 139 and 140, one of them is targeted. For example, when the camera 139 is photographing the entrance side of the mill, the imaging position is the mill position.

  As a result of this determination, if the welding points 144 and 145 have passed the imaging position, the time that the monitoring server 1011 has inside is taken in, and the front coil removal time and the rear coil entry time are specified (step S205). Then, after outputting to the video data storage means 106, it is determined whether or not the processing is completed for all the cameras 139 and 140 (step S206), but if the welding points 144 and 145 have not passed the imaging position. It is determined whether or not the processing is finished for all the cameras 139 and 140 (step S206).

  Further, if the processing is not completed for all the cameras 139 and 140 as a result of this determination, the process returns before determining whether or not the previous coil welding points 144 and 145 have passed the camera imaging position (step S204). Then, each process is repeated for the next camera (for example, the camera 140 corresponding to the subsequent stage of the camera 139). However, if the process is completed for all the cameras 139 and 140, it is the filing timing of the video data. (Step S207).

  As a result of this determination, if it is the filing timing of the video data, a file name is assigned to the video data using the time as a key (step S208) and output to the video data storage means 106, and then the operation process is terminated. If it is not the filing timing, the operation jumps to end the operation process.

  Incidentally, assuming that the rolling plant 135 is provided with a plurality of cameras 139 and 140, the video data is usually filed at the same timing. Therefore, in the first embodiment, the video filing timing is the same. Is shown. However, even in the case of cameras 139 and 140 having different resolutions, filing can be performed at different timings for each camera 139 and 140. In the file name assignment using the time as a key, for example, 20100101036. The case of mpg can be illustrated.

  FIG. 3 is a schematic view illustrating process data of the process data storage unit 104 provided in the monitoring server 101.

  Referring to FIG. 3, the process data accumulating unit 104 includes a time series process data accumulating unit 301 for storing process data received from the process data collecting unit 1033, a time at which each coil has entered the detection position of each process data. And a process time information accumulating unit 302 for storing the time when the detection position is passed as a start time and an end time, respectively.

Among these, the time-series process data storage means 301 includes the outlet side plate thickness (F4D plate thickness) of the fourth stand 149, and the tension (F1) between the first stand 146 and the second stand 147. Detection values such as (F2 tension) and F1 roll speed are stored in association with the capture time.

  Further, the process time information accumulating means 302 stores the time when the process data was detected and the time when the process data was detected for each coil. For example, the coil of the coil name A1001 is detected at the position of the fourth stand 149 outlet side plate thickness. On January 30, 2010 at 10: 30: 24.150 seconds, the measurement of the coil thickness started, and on January 30, 2010 at 10: 32: 13.310 seconds, the coil was removed. It can be seen that the measurement of this coil is completed.

  In other words, with respect to the time series data detected from the plate thickness on the outlet side of the fourth stand 149, 10: 30: 24.150 seconds on January 30, 2010 to 10: 32: 13.310 on January 30, 2010. The data up to the second indicates data corresponding to the coil having the coil name A1001.

  FIG. 4 is a schematic view illustrating the video data of the video data storage unit 106 provided in the monitoring server 101.

  Referring to FIG. 4, the video data storage unit 106 includes time-series video data storage unit 401 that stores video data received from the video data collection unit 105, and the time at which each coil has entered the imaging position of each video data. Video time information storage means 402 for storing the time when the image pickup position has been passed.

  Among these, the time-series video data storage means 401 files video data captured by the cameras 139 and 140 in units of one minute and stores them in association with the capture time. In the illustrated example, video data captured during one minute from 10:30 on January 30, 2010 by the cameras 139, 140, etc. It is stored with the file name of mpg, and thereafter, the captured start time is stored as the file name every minute for the captured video data.

  The video time information accumulating unit 402 stores the time when the video data is captured and the time when the video data is captured for each coil. For example, the coil of the coil name A1001 is stored at the imaging position of the camera 140 in January 2010. The image capture of this coil was started by entering at 10: 30: 6.110 seconds on the 30th, and the coil image was removed at 10: 31: 48.400 seconds on January 30, 2010. You can see that the import is complete.

  In other words, for the video data captured by the camera 139, the coil name A1001 is from 10:30 on January 30, 2010 to 10.30 seconds on January 30, 2010 to 10: 31: 48.400 seconds on January 30, 2010. It is shown that the image corresponds to the coil. For other cameras, video data is stored in the same manner.

  FIG. 5 is a flowchart showing an operation process of the data pack unit 108 provided in the monitoring server 101.

  The data pack means 108 processes the process data according to the conditions specified by the user from the monitoring screen 102 of the display device provided in the monitoring server 101 in the factory 100 or the monitoring screen 152 of the display device provided in the monitoring terminal 151 in the remote place 150. Data to be analyzed is extracted from the storage means 104 and the video data storage means 106 and stored in the data storage means 109.

  In the operation process of the data pack means 108 here, first, the data acquisition condition input by the user from the monitoring screen 102 or the monitoring screen 152 is taken in, and the data to be acquired is specified. In the first embodiment, as data acquisition conditions, information for specifying process data to be acquired, such as acquisition start time and end time, plate thickness, tension, the name of the camera from which video data is acquired, and video data acquisition timing are selected. Therefore, the process data to be noticed and the allowable deviation of the process data fluctuation are taken in. As a result, the process of fetching the data acquisition start / end time, process data name, camera name, variation focused process data and allowable deviation (step S501) is performed. Incidentally, if only the video data related to the time when the fluctuation of the process data exceeds the allowable value is selectively acquired, the transmission amount of the video data can be greatly reduced.

  Next, with respect to each specified process data, the process data storage unit 104 is searched, and data from the capture start time to the end time is extracted (step S502), and then attention is paid to selecting the acquisition timing of the video data. With respect to the process data (target signal), the fluctuation of the value is checked in the extracted range, and the time range in which the fluctuation of the focused signal exceeds the incorporated deviation is specified as the extracted time range (step S503).

  Subsequently, a process for extracting data in the extraction time range for each video data by adding a margin determined by a predetermined method to the video data requested to be acquired (step S504). As a result, the video data transmitted to the monitoring terminal 151 is extracted. Similarly, the video data corresponding to the time range outside the deviation range is also extracted. Actually, a video file related to the data extraction time range is extracted from the video data storage means 106.

  Further, with respect to the video data requested to be acquired, a process of extracting data in the vicinity of the welding point (step S505) is performed. Here, a predetermined range of video data around the welding point is extracted as video data to be transmitted to the monitoring terminal 151.

  Finally, the data extracted from the process data storage unit 104 and the video data storage unit 106 is stored in the data storage unit 109 (step S506), and the operation process is terminated.

  FIG. 6 is a schematic diagram showing one mode when the data pack means 108 described with reference to FIG. 5 extracts video data, by the relationship between process data (plate thickness) and video data with respect to time.

  Here, a method for specifying a time range exceeding the deviation will be described by taking as an example a case where the process data is the thickness of the steel plate 141 measured by the plate thickness meter 143.

  Referring to FIG. 6, a plate thickness deviation 602 allowed around the average value is defined for the extracted plate thickness data 601. Then, the time range in which the plate thickness data 601 falls outside the deviation range is specified as the deviation deviation range 603.

  Accordingly, margins 604 and 605 determined by a predetermined method are added to the video data requested to be acquired to obtain a time range for extracting the video data, and the video data 606 is extracted as data to be transmitted to the monitoring terminal 151. To do. Similarly, video data 607 is extracted as video data corresponding to a time range in which the plate thickness data 601 is outside the range of deviation. Furthermore, regarding the video data requested to be acquired, when data near the welding point is extracted, video data 608 within a predetermined range around the welding point 609 is extracted as data to be transmitted to the monitoring terminal 151.

  FIG. 7 is a schematic diagram showing another form when the data pack means 108 described with reference to FIG. 5 extracts video data, in relation to process data (plate thickness, tension) and video data with respect to time.

  Although the case where the process data is the thickness of the steel plate 141 has been described in FIG. 6, there may be a plurality of target process data. In FIG. 7, the thickness of the steel plate 141 measured by the plate thickness meter 143 is the target process data. And the tension of the steel plate 141 measured by the tension meter 142 are shown.

  Referring to FIG. 7, a deviation 602 and a deviation 702 are defined for the plate thickness data 601 and the tension data 701, respectively, and any one of the plate thickness data 601 and the tension data 701 deviates from a time outside the deviation range. The deviation range 703 is specified. Moreover, margins 704 and 705 are added as a time range for extracting video data, and video data 706 is extracted as data to be transmitted to the monitoring terminal 151, or as video data corresponding to a time range outside the deviation range, A point of extracting video data 708 within a predetermined range around the welding points 609 and 709 as data to be transmitted to the monitoring terminal 151 when extracting the video data 707 or extracting data in the vicinity of the welding points is shown in FIG. This is similar to the case described in FIG. In this way, the video data 706 to 708 stored in the data storage unit 10 can be extracted.

  Incidentally, if the target process data is not input or the deviation range is sufficiently large, the data pack means 108 has a function of extracting all video data between the acquisition start time and end time. Can also be supported.

  FIG. 8 is a flowchart showing an operation process of the data acquisition unit 153 provided in the monitoring terminal 151.

  The data acquisition unit 153 takes in the data pack 111 stored in the data storage unit 109 by the data pack unit 108 according to the processing procedure described with reference to FIG.

  In the operation processing of the data acquisition unit 153, first, the start / end time of the data input by the user from the monitoring screen 152, the name of the process data to be acquired, the name of the camera corresponding to the video data to be acquired, the process data to be changed and the allowable Capture deviations. As a result, the capture start / end time, the process data name, the camera name, the process data and the permissible deviation are captured, and the data is transmitted to the monitoring server 101 (step S801).

  Next, after performing processing for downloading the corresponding data pack 111 stored in the data storage unit 109 of the monitoring server 101 to the monitoring terminal 151 (step S802), the data pack 111 captured by downloading is downloaded to the terminal of the monitoring terminal 151. The operation ends after performing the process of storing in the side data storage means 154 (step S803).

  As a result, the data pack 157 stored in the terminal-side data storage unit 154 shown in FIG. 1 is displayed on the monitoring screen 152 in a list format or the like according to a user request from the monitoring screen 152 of the display device.

  Note that the data extraction unit 155 extracts the corresponding data pack 157 from the terminal-side data storage unit 154 for the data pack name requested by the user on the monitoring screen 152 and delivers it to the synchronous reproduction unit 156. Thereby, the synchronous reproduction means 156 reproduces the process data and the video data synchronously and displays them on the monitoring screen 152. Incidentally, a technique for synchronous reproduction of process data and video data is well known, and for example, the technique disclosed in Japanese Patent Laid-Open No. 5-79951 can be applied as it is.

  FIG. 9 is a diagram illustrating a display example on the monitoring screen 152 in the monitoring terminal 151. Here, process data 901 and video data 902 are synchronously reproduced and displayed on the monitoring screen 152. A time indicator 903 on the monitoring screen 152 indicates a location where the displayed video data 902 and the time are synchronized. That is, the process data at the location where the currently reproduced video data 902 and the time indicator 903 are present is data collected at the same time. During the reproduction of the video data 902, the time indicator 903 moves on the screen from the left side to the right side according to the progress of the video time being reproduced. When the time indicator 903 is clicked with the mouse and moved to the left or right, the video data 902 is switched to the video at that time. Therefore, for example, at the time when the steel plate 141 was swung on the image, how was the thickness and tension of the steel plate 141 changed, and how was the image at the time when the plate thickness and tension of the steel plate 141 were changed? Etc. can be analyzed in many ways by making full use of video data analysis and process data analysis.

  In the rolling plant monitoring system according to the first embodiment, the case where process data and video data obtained from the rolling plant 135 are handled has been described. However, even when audio data is collected instead of video data, the same configuration is applied. can do. Further, even in the case of viewing-related data in which process data, video data, and audio data are mixed, the same configuration can be applied. However, in view of the function of reproducing and displaying process data and video data in synchronization on the monitoring screen 152, it is necessary to include monitoring data storage means for storing monitoring data including at least the acquired video. Further, in the first embodiment, the process data at all times and the video data associated with the time when the variation of certain process data is large are extracted from the designated start time to the end time, and are installed in the remote place 150. Although the functional configuration transmitted to the monitoring terminal 151 has been described, since it is possible to transmit the process data limited to locations with large fluctuations, the transmission capacity can be further reduced in such a case.

  FIG. 10 is a diagram illustrating a display example on the monitoring screen 152 in the monitoring terminal 151 of the rolling plant monitoring system according to the second embodiment of the present invention.

  The monitoring screen 152, which is the display screen of the display device here, clearly indicates the time at which the video data is associated with the process data display location.

  Referring to FIG. 10, a video data extraction time zone 1001 indicated by a red line or the like on the process data display unit is added on the monitoring screen 152, and the video data is extracted in this video data extraction time zone 1001. Is extracted and included in the data pack 111 for transmission. The red line for the video data extraction time zone 1001 may be displayed in association with the time of the video data 606 to 608 shown in FIG. 6, the video data 706 to 708 shown in FIG. is there.

  As a result of the display on the monitoring screen 152 according to the second embodiment, the user can easily know the part that can be displayed by synchronously reproducing the video data in the displayed process data, thereby improving the analysis efficiency. be able to.

  FIG. 11 is a flowchart showing an operation process of the data pack unit 108 provided in the monitoring server 101 of the rolling plant monitoring system according to the third embodiment of the present invention.

  The data pack means 108 here transmits the data related to the time when the variation of the process data exceeds the allowable value to the monitoring terminal 151 with respect to the video data, and monitors the data at other times with a low resolution. The terminal 151 has a function of transmitting. However, in the operation process of the data pack unit 108, the first half is common when compared with the operation process of the data pack unit 108 according to the first embodiment described in FIG.

  Referring to FIG. 11, in the operation process of the data pack means 108, the data acquisition start / end time, the process data name, the camera name, the process data of interest and the allowable values are the operation processes common to those in FIG. A process for fetching deviation (step S1101), a process for searching the process data storage means 104 for each specified process data, and extracting data from the fetch start time to the end time (step S1102), For the process data (target signal) of interest to select the acquisition timing of the video data to be watched, examine the fluctuation of the value in the extracted range, and identify the time range where the signal of interest fluctuation exceeds the incorporated deviation as the extraction time range (Step S1103) is performed.

  Subsequently, as a different process, for each video data requested to be acquired, a time range in which a margin determined by a predetermined method is added to the time range in which the variation of the process data exceeds the allowable value, with a high resolution. It is determined as a time range for extracting video data, and data at other times is extracted with a low resolution. Thereby, with respect to each video data, processing for extracting data in the extraction time range at high resolution and extracting other data at low resolution (step S1104) is performed.

  In addition, for each video data requested to be acquired, a process of extracting data in the vicinity of the welding point with high resolution and other data with low resolution (step S1105) is performed. Here, as in the case described with reference to FIG. 6 in the first embodiment, video data 608 in a predetermined range around the welding point 609 is transmitted to the monitoring terminal 151 with high resolution. Extract as

  Finally, after the process of storing the data extracted from the process data storage means 104 and the video data storage means 106 in the data storage means 109 (step S1106), the operation process is terminated.

  According to the third embodiment, the video data can be continuously reproduced while being associated with the process data, and the transmission amount of the video data can be reduced by reducing the resolution of the video data at the time of low importance. As a process for reducing the resolution, a technique for reducing the amount of information on one screen is common, but a technique for reducing the number of frames per unit time can also be applied. For example, when transmitting data at a high resolution, 20 frames per second of video data is transmitted. When transmitting a frame at a low resolution, transmission of 2 frames per second, data is transmitted at a low resolution. Can be reduced to 1/10 of the time period for transmitting data with high resolution.

  FIG. 12 is a flowchart showing an operation process of the data pack unit 108 provided in the monitoring server 101 of the rolling plant monitoring system according to the fourth embodiment of the present invention.

  Here, the data pack means 108 shows a case where the data acquisition request is designated not by the time range but by the coil name as in each of the embodiments described above. However, the basic function itself of the data pack means 108 is as described above from the monitoring screen 102 of the display device provided in the monitoring server 101 in the factory 100 or the monitoring screen 152 of the display device provided in the monitoring terminal 151 at the remote place 150. Data to be analyzed is extracted from the process data storage means 104 and the video data storage means 106 according to the conditions specified by the user and stored in the data storage means 109.

  Referring to FIG. 12, in the operation process of the data pack means 108, first, the data acquisition condition input by the user from the monitoring screen 102 or the monitoring screen 152 is taken in, and the data to be acquired is specified. In the fourth embodiment, as data acquisition conditions, information for specifying process data to be acquired, such as a coil name to be acquired, a plate thickness, and tension, a name of a camera that acquires video data, and a video data acquisition timing are selected. Therefore, the process data to be noticed and the allowable deviation of the process data fluctuation are taken in. As a result, a process of fetching the coil name, process data name, camera name, variation focused process data and allowable deviation (step S1201) is performed. Incidentally, the transmission amount of the video data is reduced by selectively acquiring only the video data related to the time when the variation of the process data exceeds the allowable value.

  Next, with respect to each specified process data, the process data storage unit 104 is searched, and data from the coil entry time to the removal time is extracted for the coil (step S1202). That is, here, the corresponding coil name and the corresponding data name of the process time information storage unit 302 in the process data storage unit 104 are searched, and the coil entry time (start time) and withdrawal time (end time) are extracted. For example, the F4D plate thickness of the fourth stand 149 exit side of the coil name A1001 in FIG. 3 was detected at 10: 30: 24.150 seconds on January 30, 2010, and at 10:32:13 on January 30, 2010. It can be seen from the information stored in the process time information storage means 302 that the detection is completed in 310 seconds. In this way, the entry time corresponding to the detection start time of the relevant data and the missing time corresponding to the end time can be extracted for the relevant coil name. More specifically, as a result of extracting the data from the start time to the end time extracted from the time-series process data storage unit 301 regarding the corresponding process data, the coil data (entry that has been requested for extraction) related to the corresponding process data is extracted. Time, missing time).

  Furthermore, for the process data (target signal) of interest for selecting the acquisition timing of video data, the variation in the value is examined in the extracted range from the coil entry time to the coil exit time, and the deviation taken in by the signal fluctuation of interest A process is performed to identify a time range exceeding the extraction time range (step S1203).

  Subsequently, the video data requested to be acquired is added with a margin determined by a predetermined method, and the processing for extracting the data in the vicinity of the extraction time range and the welding point is performed for each video data (step S1204). .

  Finally, the data extracted from the process data storage unit 104 and the video data storage unit 106 is stored in the data storage unit 109 (step S1205), and then the operation process ends.

  In addition, the coil name designated initially may be single or plural, and may be a case where a plurality of coils are continuous or a coil rolled discontinuously. Also in the fourth embodiment, as in the third embodiment, the video data is transmitted at a high resolution for the data associated with the time when the process data fluctuates greatly, and the other data is transmitted at a low resolution. Anyway.

  FIG. 13 is a flowchart illustrating an operation process of the data acquisition unit 153 provided in the monitoring terminal 151 of the rolling plant monitoring system according to the fourth embodiment.

  The data acquisition unit 153 here has a function of loading the data pack 111 stored in the data storage unit 109 by the data pack unit 108 in accordance with the processing procedure described with reference to FIG.

  Referring to FIG. 13, in the operation processing of the data acquisition unit 153, first, the coil name input by the user from the monitoring screen 152, the name of the process data desired to be captured, the name of the camera corresponding to the video data desired to be captured, and the variation Capture the process data of interest and tolerance. As a result, the coil name, the process data name, the camera name, the process data to be changed and the allowable deviation are captured, and the data is transmitted to the monitoring server 101 (step S1301).

  Next, after performing processing for downloading the corresponding transmission data pack 111 stored in the data storage means 109 of the monitoring server 101 to the monitoring terminal 151 (step S1302), the data pack 111 acquired by downloading is downloaded to the monitoring terminal 151. After the process of storing in the terminal-side data storage unit 154 (step S1303), the operation ends.

  By the way, in the rolling plant monitoring system of each example, whether or not to acquire video data is determined by paying attention to the magnitude of process data fluctuations, the frequency components and process data obtained by Fourier transforming the process data are determined. In addition to focusing on the absolute value, a method of transmitting video data uniformly for each coil focusing on the distance from the welding point or the like can also be considered.

  Moreover, although each Example mentioned above demonstrated the rolling plant monitoring system containing the rolling plant monitoring apparatus (monitoring server 101) for the rolling plant 135 at the time of making a production product into a coil, production products other than a coil were described. The same applies to other target production plants. For example, a beer production factory that wants to monitor a production line with video data of beer fermentation and process data such as its temperature, or a food that it wants to monitor a production line with video data of beverage (liquid) and process data such as flow It can be applied to a plant or the like in the same manner.

  By the way, the technical outline according to the rolling plant monitoring system of each embodiment described above is connected to the monitoring terminal 151 installed in the remote place 150 via the communication network (public network 170), the hot rolling plant, Using the data accumulated in the monitoring server 101 installed in the vicinity of the cold rolling plant and the rolling plant 135 including the processing line, the abnormality analysis of the rolling plant 135 on the monitoring terminal 151 side and the quality of the coil that is the production product In other words, it can be said as a rolling plant remote monitoring method for performing management.

  In such a case, the rolling plant remote monitoring method of the present invention collects process data and monitoring data including at least a video from the rolling plant 135 on the monitoring server 101 side, and gives information on the capture time to the process data and monitoring data. The first step of performing, the second step of assigning the information of the capture time to the process data and the monitoring data on the monitoring terminal 151 side, and the coil name corresponding to the coil on the monitoring terminal 151 side, the process data and the monitoring data In addition to accumulating the third process to be added to and the process data to which the capture time information and the coil name are assigned on the monitoring terminal 151 side, the monitoring data to which the capture time information and the coil name are assigned are accumulated. The fourth step and the process focused on for the purpose of selecting the coil name and the monitoring data on the monitoring terminal 15 side Monitoring data in which the behavior of the fifth process for specifying the data and the process data selection condition and the behavior of the process data corresponding to the coil name on the monitoring server 101 side and the process data of interest match the selection condition are transmitted to the communication network ( Monitoring is performed using the sixth step of transmission to the monitoring terminal 151 via the public network 170), the information on the acquisition time assigned to the process data on the monitoring terminal 151 side, and the information on the acquisition time assigned to the monitoring data. And a seventh step of synchronously reproducing and displaying the video data included in the process data and the monitoring data on the screen 152.

  Also, one of the plant remote monitoring methods when the production product is other than the coil is connected to the monitoring terminal 151 installed in the remote place 150 via the communication network (public network 170) and close to the production plant. The monitoring terminal 151 side uses the data stored in the monitoring server 101 installed at the location where the monitoring terminal 151 side performs abnormality analysis of the production plant and the quality control of the product to be produced. The monitoring data including at least video is collected, the first step of adding the acquisition time information to the process data and the monitoring data, and the process data to which the acquisition time information is added are accumulated on the monitoring server 101 side. At the same time, a second process for accumulating the monitoring data to which the acquisition time information is added and the monitoring terminal 151 side Start time and end time required for acquisition, third process for designating process data of interest for selecting monitoring data, and process data selection conditions, and start time and end time required for data acquisition on the monitoring server 101 side A fourth step of transmitting monitoring data whose behavior of the process data up to and the process data of interest matches the selection condition to the monitoring terminal 151 side via the communication network (public network 170), and monitoring on the monitoring terminal 151 side And a fifth step of reproducing and displaying the video data included in the process data and the monitoring data on the screen 152.
