  Generally, from a welding point of a material to be rolled that is continuous and rolled by welding, a unit from a welding point to the next welding point is unitized as a coil. When used for the purpose of remotely monitoring a rolling plant using information mixed with data, there are the following problems. That is, even if the coils processed in the rolling plant are the same coil, the processing start time and end time are different between the upstream facility and the downstream facility of the rolling plant. Japanese Patent Application Laid-Open No. 9-85315 does not take this point into consideration, so that it is not possible to extract data of the same coil in consideration of the fact that the start time and end time of processing differ for each collected data.

  Further, when the technique disclosed in Japanese Patent Laid-Open No. 5-79951 is used for remote monitoring, it is necessary to exchange large volume data including video information between the remote side and the rolling plant side during the analysis. For this reason, there has been a problem that the amount of transmission through the Internet becomes large and the responsiveness of the analysis screen is lowered.

Process data and video data corresponding to the coil are extracted, a coil data pack is constructed as a set of data associated with the coil, and the coil data pack is stored.

  In addition, process data and video data are collected from rolling plants such as a hot rolling plant, a cold rolling plant, and a processing line, time information is given to the process data and video data, and a coil name is added to the process data and video data. The process data and video data to which the time information is given and the coil name is given are stored, and the process data and video data corresponding to the designated coil name are stored for the designated coil name. Take out, link to the coil name, store it in another area, and when the coil name is specified from a remote monitoring terminal, process data and video corresponding to the coil name from the accumulated process data and video data The data is imported to the monitoring terminal and assigned to the process data and video data for the specified coil name. Using time information, and configured to play synchronously process data and the video data captured by the monitoring terminal.

  According to the present invention, monitoring of a rolling plant using video data and process data can be made highly responsive.

It is explanatory drawing of a video data storage means. This is processing of the coil data pack means. It is a process of a coil data acquisition means. It is explanatory drawing of the monitoring screen. This is processing of the coil data pack means.

  Since the analysis using the process data and video information can be performed from the remote to the rolling plant with high responsiveness, it is possible to improve the monitoring control efficiency and maintainability of the rolling plant.

  FIG. 1 shows an embodiment of the present invention. The whole consists of a rolling plant 135 and a factory 100 where the monitoring server 101 is located, a remote area 150 where the monitoring terminal 151 is located, and a public network 170 which connects them via the Internet. The monitoring server 101 and the remote area 150 are monitored in the factory 100. The terminal 151 performs communication via the public network 170.

  First, equipment and processing in the factory 100 will be described. In this embodiment, the monitoring target is the rolling plant 135. The rolling plant 135 may constitute a hot rolling plant, a cold rolling plant, a processing line, or the like. In this embodiment, 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. The steel plate 141 is connected to the rear steel plate by a welding point 144 and the previous steel plate by a welding point 145, and so-called continuous rolling is performed. The welding point 144 to the welding point 145 is a coil that is a winding unit of the steel plate. Of course, an arbitrary point may be used as a coil from other arbitrary points. Various measuring instruments and cameras are attached to the rolling plant 135 in order to detect the state of the steel plate 141 and equipment. As an example, the thickness gauge 142 measures the thickness of the steel plate 141 on the exit side of the first stand 146, and the thickness meter 143 measures the thickness of the steel plate 141 on the exit side of the fourth stand 149. Generally, in addition to this, a plate speedometer for detecting the moving speed of the steel plate 141, a tensiometer for measuring the force with which the steel plate 141 is pulled between the stands, a shape meter for measuring the balance of the elongation in the width direction of the steel plate 141, and the like are provided. It is done. In the present application, the data measured by these is collectively referred to as process data. In FIG. 1, the camera 140 captures the state on the first stand entry side as video information. Similarly, the camera can be mounted at various positions depending on the purpose. The steel plate 141 is rolled at the rolling plant 135 and then cut in the vicinity of the welding points 144 and 145 and wound as a coil. Generally, a coil is a unit for quality control of a rolled steel sheet.

  The controller 130 fetches the record data from the rolling plant 135, controls the rolling plant 135, and transmits the fetched record data to the monitoring server 101 via the network 133. The encoder 131 similarly transmits the video information captured from the camera 140 to the monitoring server 101 via the network 133. Hereinafter, each function of the monitoring server 101 is also referred to as “... Means”. For example, the monitoring server 101 is configured by one or a plurality of computers, and each function indicated as “. Of course it is good. The same applies to the monitoring terminal 151. The monitoring server 101 stores process data collected by the process data collection unit 103 that collects process data sent from the controller 130, stores process data collected by the process data collection unit 103, and sends it from the encoder 131. The video collection means 105 for collecting the incoming video data, the video data collected by the video collection means 105 are stored, the video data accumulation means 106 for accumulating, and the process data and the video data for specifying the data collection time Time giving means 107 for giving information (collection time is a time synchronized with data detection (same time), hereinafter also referred to as time information), receives the coil name given to process data and video data from the host computer, and Data storage means 104 and video data storage means 10 For the coil requested by the user from the coil name assigning means 110 and the monitoring screen 102 to be output, the data of the corresponding coil stored in the process data storage means 104 and the video data storage means 106 are extracted and linked to the coil name. Coil data pack means 108 for constructing a cluster of data based on the data, and coil data storage means 109 for accumulating the data cluster associated with the coil name in units of coils. In the figure, coils A1001 to C1029 are stored in the coil data storage means. On the monitoring screen, the accumulated data can be displayed and a coil name to be stored in the coil data accumulation means 109 can be input.

  Next, devices and processing in the remote place 150 will be described. The remote place 150 is provided with a monitoring terminal 151 and a monitoring screen 152 for monitoring the state of the rolling plant 135. The monitoring terminal 151 is connected to a network 157, a gateway 158 on the remote site 150 side, a public network 170 (for example, the Internet (TCP / IP protocol), LAN (IEEE802 protocol) may be used), a gateway on the 100 side in the factory. It is connected to the network 133 in the factory via 132, and can exchange signals with the monitoring server 101. The monitoring terminal 151 acquires coil data from the coil storage unit of the monitoring server 101 for the coil requested by the user from the monitoring screen 152, and stores the acquired data in the coil data acquisition unit 153 stored in the coil data storage unit 154. The terminal side coil data storage unit 154 that stores the coil in association with the coil name, and the coil that extracts the coil from the terminal side coil data storage unit 154 for the analysis target coil requested by the user from the monitoring screen 152 The data extraction means 155 is provided with synchronous reproduction means 156 for synchronously reproducing process data and video data with respect to the extracted coil.

  Hereinafter, the operation of each unit will be described in detail. FIG. 2 shows the processing of the time giving means 107. The purpose of adding time information is to synchronize and reproduce process data and video data, and to attach information for identifying which coil each data corresponds to. 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 in accordance with the required time accuracy (in the following embodiments, every 10 msec). In S2-1, it is determined whether or not the welding points 144 and 145 of the coil have passed the detection position of this process data for one of the process data. When the welding point has not passed, the process proceeds to S2-3. When the welding point passes, the time that the monitoring server 101 has in S2-2 is taken in, and this time is specified as the previous coil withdrawal time and the rear coil entry time, and the process data storage means To 104. That is, next, in S2-3, it is determined whether or not the processing has been completed for all process data (for example, at least F4D plate thickness, F1_F2 tension, F1 roll speed, etc.). The processes of S2-1 to S2-3 are repeated for the process data. If it has been completed, it is determined in S2-4 whether or not the coil welding points 144 and 145 have passed through the imaging position of this camera for one of the cameras. For example, when the camera is photographing the entrance side of the mill, the imaging position is the mill position. When the welding point has not passed, it progresses to S2-6. When the welding point passes, the time that the monitoring server 101 has in S2-5 is taken in, the previous coil withdrawal time and the rear coil entry time are specified, and output to the video data storage means 106 To do. Next, in S2-6, it is determined whether or not the processing has been completed for all the cameras (at least the camera 140 ...). If not, the processing of S2-4 to S2-6 is performed on the next camera. repeat. If it has been completed, it is determined in S2-7 whether or not it is the filing timing of the video data. Even when the rolling plant 135 is equipped with a plurality of cameras, video data is usually filed at the same timing. Therefore, this embodiment also shows a case where the video filing timing is the same. In such a case, filing can be performed at different timing for each camera. At the filing timing of the video data, a file name with the time as a key, for example, 201001301036.mpg is assigned to the video data in S2-8 and output to the video data storage means 106.

  FIG. 3 shows the configuration of the process data storage unit 104. The process data accumulating unit 104 stores the time series process data accumulating unit 301 for storing the process data received from the process data collecting unit 103, and the time when each coil enters the detection position of each process data and the time when the detection position is passed. The process time information storage means 302 stores the start time and the end time, respectively. Here, the welding point 145 of the coil is detected at 2011.1 / 30/10: 30: 24: 150 by the F4D plate thickness detector, and then the F4D plate thickness is detected every 10 msec. Then, the next welding point 144 is detected at 2011.1 / 30/10: 32: 13: 310. Similarly, the welding point 145 of the coil is detected by the F1_F2 tension detector at 200.1 / 30/10: 30: 13: 440, and then every 10 msec and the next welding point 144 is It is detected at 30/10: 32: 02: 760. Further, the welding point 145 of the coil is detected by the F1 roll speed detector at 2010.1 / 30/10: 30: 30: 12: 010, and every 10 msec thereafter, and the next welding point is set to 2011.1 / 30 / It is detected at 10: 32: 01: 330. The time-series process data storage means 301 is configured to detect a detection value (the first stand 146 and the first stand 146 and the first stand 146 and the second stand 147, the tension (F1_F2 tension) between the first stand 146 and the second stand 147). A tension meter (not shown) is provided between the two stands 147.), a roll speed (F1 roll speed) of the first stand 146, and a motor (not shown) is provided on the motor that rotates the work roll of the first stand 146, The roll speed F1 is detected by this speedometer. It is stored in association with the capture time. The process time information accumulating means 302 stores the time when the process data entered the detection position of each process data and the time when the process time information is stored. For example, the coil of the coil name A1001 detects the fourth stand outlet side plate thickness. The measurement of the thickness of this coil was started by entering the position at 10: 30: 24.150 seconds on January 30, 2010, and the coil was removed at 10: 32: 13.310 seconds on January 30, 2010. Thus, 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 fourth stand outlet side thickness gauge, January 30, 2010 10: 30: 24.150 seconds to 2010 January 30, 10: 32: 13.310 seconds. The above shows that the data corresponds to the coil of the coil name A1001.

  FIG. 4 shows the configuration of the video data storage means 106. The video data storage means 106 includes a time-series video data storage means 401 for storing the video data received from the video collection means 105 (video data), the time when each coil entered the imaging position of the video data, and the imaging position. The video time information storage means 402 stores the stored time. The time-series video data storage unit 401 files video data captured by the camera 140 in units of one minute, and stores it in association with the capture time. In the example of the figure, the file name is directly named as the capture time, and the video data captured by the camera 140 for one minute from 10:30 on January 30, 2010 is stored as the file name 201001301030.mpg. ing. Hereinafter, the captured start time is stored as a file name every minute. The video time information accumulating unit 402 stores the time when the video data entered the imaging position of each video data and the time when the video data is stored. For example, the coil of the coil name A1001 is stored at the imaging position of the camera 140 on January 30, 2010. By entering at 10: 30: 6.110 (the welding point 145 was detected by the camera), the capture of the image of this coil was started, and the coil was removed at 10: 31: 48.400 on January 30, 2010. (The welding point 144 is detected by the camera), it can be seen that the capturing of the image of this coil is completed. In other words, with respect to the video data shot by the camera 140, the coil name A1001 is from 10:30 on January 30, 2010 to 6.30 seconds on January 30, 2010 at 10: 31: 48.400 seconds. It shows that the image corresponds to the coil. For other cameras, video data is stored in the same manner.

  FIG. 5 shows the processing of the coil data pack means 108. The coil data pack means 108 extracts the data associated with this coil from the process data storage means 104 and the video data storage means 106 for the coil specified by the user without excess or deficiency, and stores the coil data using the coil name as a key. Store in means 109. In S5-1, the coil name input from the monitoring screen 102 by the user is acquired, and the coil to be processed is specified. In S5-2, the start time of the corresponding coil name of the process time information storage unit 302 and the start time of the corresponding coil name of the video time information storage unit 402 are searched for the identified corresponding coil, and all the processes are searched. The oldest start time is extracted from the data, and this is set as the first time (F1 roll speed 2012.1 / 30/10: 30: 30: 12: 010 in the example of FIG. 3). Similarly, for the corresponding coil, the end time of the corresponding coil name in the process time information storage unit 302 and the end time of the corresponding coil name in the video time information storage unit 402 are searched, and the latest end time is extracted. Is the second time (in the example of FIG. 3, the F4D plate thickness is 201.1 / 30/10: 32: 13: 310). In step S5-3, the time series process data storage unit 301 is searched, and data from the first time to the second time is extracted as process data associated with the corresponding coil. Similarly, in S5-4, the time-series video data storage unit 401 is searched, and the video data including the video at the second time from the video file including the video at the first time is linked to the corresponding coil. Extract as For example, when the first time is 10: 29: 45.150 seconds on January 30, 2010 and the second time is 10: 34: 24.450 seconds on January 30, 2010, 201001301029.mpg to 201001301034.mpg Is extracted. The process data and video data associated with the coil name extracted in this way is called a coil data pack. In S5-5, the coil data pack is stored in the coil data storage means 109. As shown in FIG. 1, the coil data storage unit 109 stores a coil data pack 111 in units of coils.

  In this embodiment, an example is shown in which the user designates a single coil and constructs the coil data pack 111 according to the designated coil. However, the coil data pack 111 is constructed according to a plurality of coils that are continuously rolled. This can also be realized with the same configuration. In general, rolling troubles and quality defects are likely to occur in the vicinity of the welding point, and therefore, analysis of the vicinity of the welding point can be continuously performed by configuring the coil data pack 111 with a plurality of continuous coils.

  FIG. 6 shows the processing of the coil data acquisition unit 153 provided in the monitoring terminal 151. The coil data acquisition unit 153 takes in the coil data pack 111 specified by the user from the coil data storage unit 109 of the monitoring server 101 to the monitoring terminal 151 side in accordance with a user request from the monitoring screen 152. In S6-1, the coil name input from the monitoring screen 152 by the user is taken in, and the coil to be acquired is specified. In S6-2, the coil data pack 111 corresponding to the corresponding coil is downloaded from the coil data storage unit 109 of the monitoring server 101 to the monitoring terminal 151. In S6-3, the coil data pack taken in by downloading is stored in the terminal-side coil data storage unit 154 as the coil data pack 157 in the same manner.

  The coil data pack 157 stored in the terminal-side coil data storage unit 154 is displayed on the monitoring screen 152 in the form of a list or the like according to a user request from the monitoring screen 152. The coil data extraction unit 155 extracts a coil data pack 157 corresponding to the coil name requested by the user on the monitoring screen 152. Then, the synchronous reproduction means 156 performs synchronous reproduction. A technique for synchronous reproduction has already been established, and a method established by a known technique (for example, already disclosed in JP-A-5-79951) may be used.

  FIG. 7 shows an example of a screen in which process data and video data are reproduced in synchronization on the monitoring screen 152. Process data 701 and video data 702 are displayed on the screen. A time indicator 703 indicates where the displayed video data and the time are synchronized. That is, the currently reproduced video data and the process data where the time indicator exists are data collected at the same time. While video data is being played back, the time indicator moves from left to right as the video time being played back advances. When the time indicator is clicked with the mouse and moved left and right, the video data is switched to the video at that time. Therefore, at the time when the steel plate 141 was swaying on the image, what was the change in the plate thickness and tension of the steel plate, what was the image at the time when the plate thickness and tension of the steel plate was changing, etc. Using data analysis and process data analysis, it is possible to perform multifaceted analysis.

  Thus, all process data and video data are extracted in the same range from the first time to the second time and stored in the coil data storage means 109. Therefore, display and synchronized playback can be performed in any combination with the time as the horizontal axis.

  In this embodiment, process data and video data have been described as examples. However, the present invention can be applied with the same configuration even when audio data is collected instead of video data. Even when process data, video data, and audio data are mixed, the present invention can be applied with the same configuration.

  Next, a second embodiment of the present invention will be described. The difference from the first embodiment is the content of the data included in the coil data pack. In the first embodiment, the tip of the steel plate 141 corresponding to the coil enters the rolling plant 135 and the tail is the rolling plant 135. Whereas all the process data and video data until exiting the process are stored in association with the coil name, in this embodiment, the detection position of each process data and video data is set in the steel plate 141 corresponding to the coil. The data until the tip enters and the tail tip comes off is linked to the coil and stored.

  FIG. 8 shows the processing of the coil data pack means 108. In this embodiment, the coil data pack means 108 extracts data associated with the coil from the process data storage means 104 and the video data storage means 106 for the coil specified by the user without excess or deficiency, and sets the coil name as a key. Is stored in the coil data storage means 109. In S8-1, the coil name input from the monitoring screen 102 by the user is acquired, and the coil to be processed is specified. In step S8-2, the process data storage unit 104 is searched to extract process data from the start time to the end time. That is, the process time information storage means 302 is searched for each process data of the corresponding coil, the start time and the end time are recognized, and the process data in the corresponding range is processed as the process data associated with the corresponding coil. Extract from the storage means 301. Similarly, in S8-3, the video data storage means 106 is searched to extract video data from the start time to the end time. That is, the video time information storage means 402 is searched for the video data of the corresponding coil, the start time and the end time are recognized, and the video data in the corresponding range is stored as the video data associated with the corresponding coil. Extract from means 401. For example, when the start time is 10: 29: 45.150 seconds on January 30, 2010 and the end time is 10: 34: 24.450 seconds on January 30, 2010, 201001301029.mpg to 201001301034.mpg are extracted. . In S8-4, the coil data pack is stored in the coil data storage means 109. As shown in FIG. 1, the coil data storage unit 109 stores a coil data pack 111 in units of coils.

  According to the present embodiment, since only the data corresponding to the corresponding coil is extracted for each process data or video data to constitute the coil data pack 111, the amount of data included in the coil data pack 111 compared to the first embodiment. There is an advantage that can be reduced.

  The present invention can be widely applied as a monitoring device for a rolling plant that manages quality in units of coils, such as a hot rolling plant, a cold rolling plant, and a processing line. Also, for example, in a plate rolling plant, product quality is managed on a plate-by-plate basis, so that the present invention can be similarly applied. Thus, if it is a plant which performs quality control by a specific unit, it can apply widely by replacing the coil shown in the present Example with the unit of quality control.

  As described above, to summarize the embodiment, a monitoring server is provided at a location close to the rolling plant, and a monitoring terminal is provided at a remote location, and they exchange information via the Internet. Then, on the monitoring server side, coil data pack means for extracting data corresponding to the coil name and extracting data that is sufficient for analyzing a specific coil from the accumulated process data and video data, and packed in coil units Coil data storage means for storing data is provided. In addition, on the remote monitoring terminal side, the coil data acquisition means that can select and fetch data from the coil data storage means of the monitoring server in units of coils, and the coil to be analyzed are selected from the captured coils. Coil extraction means and synchronous reproduction means for reproducing process data and video information in synchronization are provided.

  The coil data pack means provided in the monitoring server selectively extracts only the data related to the coil from the accumulated process data and video data for the coil designated by the user, and associates the coil with the coil name. Store in the data storage means. The coil data acquisition means provided in the monitoring terminal takes in the coil data pack of the coil designated by the user by downloading from the monitoring server to the monitoring terminal.
