Description

Technical field

The present invention relates to a workflow management system and a workflow management method for efficiently recording and controlling the tightening of a large number of bolts and screws to a specified torque value.

BACKGROUND OF THE INVENTION

In practice, for example, during the maintenance and inspection of the bolt tightening of the equipment device, the operator tightens the bolt, after which the work group supervisor checks the action, thus avoiding bolt tightening, failed tightening, and the like.

However, a large number of bolt tightening operations are more likely to result in poor tightening or non-tightening of the bolt, making it difficult to completely avoid such malfunctions. Existing work-based management and training, which depends on human skills, is inadequate and therefore difficult to avoid.

Conventional systems for resolving such work execution errors are known in patent documents 1 and 2.

In the control system described in patent document 1, the operator must first carry out the work-step test process, and the primary (reference) image obtained from capturing the work-test run is preserved. Thereafter, each time the operator performs an action in a work operation with the target operation object and completes that action, an image of this technological operation is captured. The image of the technological operation is then checked against the reference image. If the captured image is found to be substantially consistent with the reference image, and the technological operation can be identified by all reference images, then the action on the target object of the operation is considered complete.

However, compared to a previously captured reference image, the subject of the operation may change due to environmental conditions, wear, defects, or the like. Consequently, when the captured image is subsequently compared with the reference image, differences may occur which complicate the identification process. In addition, when the target of the operation is a large number of bolts placed on a circular flange or similar surface, it is difficult to match the bolts with other bolts and identification is very difficult.

The control system described in patent document 2 is a system using a wrench that, upon reaching the set value of bolt tightening torque, activates a releasing mechanism that uses the actual torque value of the bolt acting as the value of the actual torque applied to the bolt, e.g. the value at which the upward trend changes to the downward trend and thus controls the degree of bolt (screw) tightening.

But when the target object has a large number of bolts, it is not possible to determine whether the particular bolt is the bolt that has already been tightened or the bolt that will still be tightened, and this is not discussed. The identification code assigned to the component is used to achieve the specified torque of the target object.

An example embodiment of the invention

The implementation of the work management system and work management method according to the present invention is described in more detail below with reference to the accompanying drawings. In this embodiment of the invention, the following will be described using a valve or the like which is the target of the operation as a technological operation object and, as a target component of the operation, an additional element such as a valve bolt subject to tightening.

FIG. 1 is a schematic diagram of a process control system for carrying out the present invention. FIG. 2 is a block diagram of a performance management system according to the present invention. As shown in the drawings, the work control system 10 of the present invention comprises, as a basic base structure, a work terminal 20 for operating an operator in a work bar; an image capturing terminal 30 capable of recording an action state and transmitting the captured image to a work terminal; a work tool 40 to be used during the operation and capable of transmitting the measurement value to the work terminal; and a control terminal 50, which is located in a control location such as an office space, away from the work bar, and can transmit and receive data from the work terminal.

The work terminal 20 comprises, at a minimum: a reading unit 22, which can read externally the exposed subject and control data of the target object of the operation, including a list of the operation specification of the exposed subject; a data entry unit 24 which can perform data entry related to the subject and the operation specification which are read by the read unit 22; an image processing unit 26 capable of receiving and processing a captured image of an operation target object and a target action component; a control unit 28 capable of receiving a measurement value of the target action component used in the operation specification and an image processed by the image processing unit 26 representing a target object of the operation on a screen that selectively selects the target action component subject to the operation target object selected in the operation specification; which captures an image captured by the target component of the action for which the action is performed, and which can generate operational data that replaces the selection mark on the screen with a performance mark, displaying and recording the mark of performance; and a data storage control unit 29 which temporarily stores the operational data and control data.

The reading unit 22 reads the control data transmitted from the control terminal 50 to the data storage control unit 54. The control data is control data, operation references, associated equipment, operation object, operation specification, and the like, due to an action previously recorded by the manager.

Data Entry Unit 24 enters or selects operator, workgroup manager, and work bar controller names including job operation, operator information such as password, exposed object operating parameters, operation specification, and tool and the like.

The image processing unit 26 receives the image captured by the image capturing terminal 30 and processes it into an image that may be displayed at an image location on the screen of the work terminal 20.

The control unit 28 controls the operation of the work terminal 20. The measured value transmitted from the work tool 40 and the image data from the image processing unit 26 are input to the control unit 28. Based on the control data read from the control terminal 50, the control unit 28 records the measured value of the work bar and captures the image to operational data. The control unit 28 then records the input data from the data entry unit 24 to the operational data and forms an operation record. Based on the input data, the control unit 28 records the start time of the operation and the time of completion of the operation. The control unit 28 obtains the difference between the number of target action components of the previously registered operation object and the number of actions actually performed, and can thus determine the number of remaining operations.

The data storage control unit 29 receives and temporarily stores the transaction data generated in the control unit 28 and the control data read from the control terminal 50.

The video capture terminal 30 is a camera capable of recording a state where the operator actually performs an action in a work bar with the target object of the operation and the target action component. The image capture terminal 30 is electrically connected to the image processing unit 26 of the work terminal 20 with or without wires, and can transmit the captured image to the image processing unit 26. In this embodiment, the image capture terminal 30 is removably mounted so that it can be captured. an image of a state prior to the state when the operator actually performs an action on the target object of the operation, and a state where the operator performs an action on the target action component using a tool. When the operation object has a large number of target action components, then the image capture terminal 30 captures separately the image of the target action component for which the action has been completed. The image capture terminal 30 can adjust the auto exposure and auto focus, and can use a CCD camera to convert optical information into an electrical signal.

The working tool 40 is a tool for performing a bolt, screw, or similar tightening operation. In this embodiment of the invention, an exemplary description is provided using a torque limiting key. This wrench (wrench) is wirelessly coupled to the control terminal 28 of the work terminal 20 and is provided with a stop (torque actuator) that releases the tightening when the set torque value is reached and the load is set below the set torque value. Wrenches are also connected to the wrench, which can measure the tightening torque and transmit the torque value to the control unit 28.

The management terminal 50 is a management computer where the manager can pre-record details of the operation. The control terminal 50 may transmit and receive operational data and control data using the work terminal 20. The control terminal includes as a basic base structure a read unit 52, a data storage control unit 54, a data input unit 56 and a document generation unit 58.

The read unit 52 reads the operational data transmitted from the data storage control unit 29 of the work terminal 20 The operational data is data generated in the terminal 20, such as a measured value of the tool recorded when the operator performs an action in a work bar and a work operation object or target action component. captured image.

The data storage control unit 54 stores and manages the operational data received at the work terminal 20 and the predefined bar work control data.

Document Generation Unit 58 generates a document, such as a daily progress report based on operational data retrieved from the work terminal.

The data entry unit 56 preprograms control data such as operation control number, operation reference, associated equipment, operation purpose, and operation specification.

The following is a workflow management method using the workflow management system 10 of the present invention, the configuration of which is described above.

FIG. 3A is an illustrative diagram of the control terminal control menu. FIG. 3B is an explanatory diagram of the control terminal action registration. The manager first connects to the management system using the management terminal 50 to perform the registration of the action. When the manager connects to the management system as shown in Figs. 3A, the control menu screen 200 is displayed. By pressing the action log button 201 on the screen, as shown in FIG. 3B, the display switches to an action logging screen 202, and operation control no. Operation reference 204, associated equipment 205, operation objective 206, and operation specification 207. For example, if operation reference 204 is an operation with a pressure valve, associated equipment 205 and operating purpose 206 may be selected. Thereafter, if the operation target reference 206 selects the pressure valve as the action target, the operation specification 207 shows the housing tightening bolt and the drive cap tightening bolt which are the target action components. The operation specification 207 can also press the change button 208 for many other operations specification references. When registration is complete, press the OK button 209 to save the operation references. After saving, the screen returns to the control menu screen 200 as shown in FIG. 3A.

FIG. 4 is a flowchart of a work terminal execution process according to the present invention.

At work terminal 20, the person involved in the operation is first registered (step 1). FIG. 5A, 5B are explanatory diagrams of a work terminal login screen. In this embodiment of the invention, a controller 210, a task manager 211, and an operator 212 are registered. 5A, the input data is name 213 and password 214, which when pressed, the registration button 215. A large number of operators 212 can be registered. After registration, the display boxes showing controller 210, workgroup manager 211 and operator 212 change color. Afterwards, as shown in Figs. 5B, the start button 216 of the action becomes active, thus enabling the operation to begin.

FIG. 6A, 6B are explanatory diagrams of the work terminal check-in / check-out screen. Referring to FIG. 5B check / unlock button 217 as shown in FIG. 6A, the screen switches to the check-in / check-out screen 218. On the work terminal 50, the office PK field 219 shows the action object. When the action object to be unregistered is selected, the screen color changes, and when the unregister button 220 is finally pressed, as shown in FIG. 6B, the action object to be de-registered is displayed on the screen in terminal box 221. After this operation, the data of step 50 in the control terminal is transferred to part 20 of the work terminal. The button 222 is finally pressed and the check-in / check-out screen 218 closes.

FIG. 7A is an illustrative diagram of a work terminal login screen. FIG. 7B is an explanatory diagram of a work terminal action selection screen. As shown in Figs. 7A, by pressing the start button 216 of the current operation, the operator is started (step 2), the start time of the operation is recorded, and the execution time of the operation is started (step 3).

As shown in Figs. 7B, the action selection screen 223 is displayed on the screen. The action selection field displays a list of operation objects previously scanned from the control terminal 50. A selection of the operation object (in this embodiment is a pressure valve operation) for which the action is performed , and then press the OK button (here button 224) (Step 4).

FIG. 8A, 8B are explanatory diagrams of the work terminal registration screen prior to operation. As can be seen from Figs. 8A, the registration screen 225 shows the action of the pressure valve in the operation reference box 226 and the device number in the associated device 227, and thus allows the operation reference and the selected associated device to be continuously checked. The target object of the operation is then checked (Step 5). To record the purpose of the operation, an image capture terminal 30 is used which is connected to the work terminal 20 while filming the associated device (operation object). After confirming that the associated device is displayed on the preview screen 228, press the capture button 229 to record the video.

The captured image of the associated device is displayed on screen 230. Then, as shown in FIG. 8B, in the operation specification selection box, select the operation reference (in this embodiment, the shell-body mounting screw 231) (step 6), press the OK button (here button 232), and switch the display to the operation object identification screen.

In this embodiment of the invention, the description is provided using a wrench as a working tool. FIG. 9A is an explanatory diagram of a work terminal key with a torque limit (wrench) settings screen. FIG. 9B is an illustrative diagram of a job terminal job execution screen. On the wrench settings screen, 233 operator information is the first input for operator registration (Step 7). As shown in Figs. 9A, the operator 234, the workgroup manager 235, and the controller 236 are selected on the screen for the object responsible for the object, and in this embodiment, the operator performs a tightening action, followed by the workgroup manager describing the tightening action. The tool settings are then logged. The control registers control number 237 for registering wrench settings. The control number is a predefined wrench control number and can be selected from the enrollment list. Thereafter, after setting the wrench control number, the display shows the target value 238 set for the selected wrench torque value and interval 239. In the display set value field 240, the operator specifies the target value 238 set by selecting the wrench torque set (step 8). When the setting value is entered, the OK button (in this case the 241 button) is activated. If the value entered is outside the target value range, the OK button does not become active. Pressing the OK button switches the screen to the action screen.

As can be seen from Figs. 9B, Action screen 242 shows: Operation Specification List 243, Associated Device 244, and Operator 246, as well as a Procedure Instruction Reference Button 247 for navigating to a previously registered Operation Command, Number Field 248 corresponding to the number of target action components. schematic diagram of target object and target action component 249 (in this embodiment, schematic plan of 12 tightening bolts mounted on a valve), tightening point 250, tool control number 251, and torque value 252. In this way, the operator can during operation constantly check the tightening point, wrench control number and torque value for a particular operation.

When the bolt tightening operation begins (step 9), the number of screws to be tightened (step 100) is determined. Specifically, determining the number of screws to tighten results in a difference between the number of pre-recorded target action components of the operation object and the number of times the action is actually performed, and thus determines the remaining number of action steps (step 109).

The bolt number of the target action component is first selected. FIG.

10A is an explanatory diagram of the work terminal action on the screen tightening operation. FIG.

10B is an explanatory diagram of the action screen of a work terminal filming screen.

After starting the operation, for example, when bolt number 1 is selected, as shown in FIG.

The IOA, the location corresponding to screw number 1 (248), is represented by a selection mark (circle) 249 in the target screen component drawing on the rendering screen, thereby recognizing the tightening screw during action (step 101). A pop-up screen 250 appears and records the start time of the bolt tightening operation (step 102). The operator then performs a tightening operation on bolt number 1 using a wrench (step 103). In the target action component box, the bolt is not numbered and the operator can select any bolt from a large number of bolts. When the screw tightening reaches the set value, the stop (step 104) is activated, the tightening is terminated and the measured torque value is transmitted to the work terminal. By pressing the on-screen tightening button 251 as shown in FIG.

In the IOB, a pop-up captured video screen 252 appears. In pop-up screen 252, an image performing a bolt number 1 tightening operation using a wrench is obtained at the capturing terminal as a viewing screen 253. Pressing the capture button 254 captures the capturing terminal. the captured image is transmitted to the work terminal.

FIG. 11A is an explanatory diagram of an image setup job terminal operation screen. FIG. 11B is an explanatory diagram of performing a tightening action on the work terminal action screen. As can be seen in Figs. 11A, after the captured image 255 is displayed on a pop-up screen 252 and the captured image is confirmed by pressing the set button 256, the captured image pop-up screen 252 is closed. As shown in Figs. 11 B, bolt number 1, previously subjected to a tightening and filming operation, is marked on the screen by a performance sign 257 indicating the completion of the operation. Also, an execution mark 258 is circled to mark the target action component on the drawing of the target object of the operation and record the time for performing the bolt tightening action (step 106). Then, operational data, including a photograph (step 107) is created and stored in the data storage control unit of the work terminal 20. The number of steps is then used to count the number of times the bolt has been tightened (step 108).

Then, if there is a large number of target action components, the determination is performed according to step 109 as described above. FIG. 11B shows how a pop-up screen 259 appears at the work terminal 20 to indicate whether the bolt tightening operation is performed continuously. As a result of the adjustment, when the bolt tightening operation has been performed, the YES button 260 is pressed and the steps from step 101 to step 108 are repeated for bolts 2 through 12.

FIG. 12 is an explanatory diagram of the action execution job terminal on the action execution screen. As shown in the drawing, when all large numbers of bolts are tightened, an action mark 257 is added to the display of all bolt numbers in the action execution screen, as well as an action mark 258 for all target action components in the target object drawing of the operation. A pop-up screen 260 is displayed. Pressing OK 261 closes the pop-up screen. When pressing the operation completion button 262 on the screen as shown in FIG. 9A, the screen switches to a wrench settings screen 233. After the operator completes the tightening operation when the tightening operation is performed by the workgroup manager, the workgroup manager 235 liability instruction in the operator registration shown in FIG. 9A. The same tightening action as the operator is performed by the workgroup leader.

After the workgroup leader completes the tightening operation when the operation end button 262 shown in FIG. 12, the screen is switched to the action selection screen 223 shown in FIG. 7B. Pressing the action button on the action selection screen 263 completes the measurement of the operation time (step 110), records the end time of the operation, and the operation on the selected operation object is completed (step 111).

FIG. 13 is an illustrative diagram of the Operational Data Management List. In this embodiment of the invention, the operation specification action start time 264 and action end time 265 and start time 266 and end time 267 are retained relative to the target action component of the tightening operation. Using these types of recorded data, as shown in the drawing, it is possible to create a list of time 268 270 by specification of the operation organized by the responsible person and the time spent by each component of the target action 269.

In the above described execution management system of the present invention, the target action component can be readily identified among the operation targets displayed on the screen. Using a work terminal, it is also easy to record the measurement value during the operation and the image after the operation. Then, after completing the action, the target action component at which the operation was completed is highlighted on the screen to identify a large number of target action components in the operation object. Thus, it is possible to avoid working errors such as bolt tightening and to make a record of the operation.

FIG. 14 is an illustrative diagram of the means of identification. The identification means 60 is formed in an adapter 62 connected to the target object of the operation. The adapter 62 in this embodiment of the invention is in the form of a ring that can be mounted on the valve of the operation target object 70 as shown in the drawing and contacts the operation target object on the inner surface of the ring. The inner ring surface of the adapter 62 has a projection 64 that can contact and be fixed to the side surface of the fastening screw of the target action component 72. The identification means 60 is mounted on the upper surface of the adapter 62 to match the location of the screw. The identification means 60 in this embodiment is an identification tag obtained by matching a plurality of colors and is applied to the location of the adapter 62 corresponding to each of a plurality of components. A means is used whereby, after capturing an image of an adapter, the number and position information of the components to which the tag is affixed can be automatically recognized on the image capture screen.

The tightening operation using the identification means 60 described above is performed as described below. The adapter 62 with the identification means 60 is attached to the operation target object 70. The identification means 60 is mounted to each of the plurality of target action components 72. The inspection object 70 captures a related device ( operation target object). After verifying that the operation target object 70 and the identification means 60 are displayed on the preview screen, the movie button is pressed to capture a still image or moving images. Using the identification means 60, the position information of the target action component 72 can be identified in the captured image. This is followed by tightening the target action component 72. The identification means 60 mounted on the target action component 72 subject to the action process is concealed behind a wrench which is a working tool 40. When the target action component 72 is filmed after the tightening operation is completed, the identification means 60 is not displayed on the screen. The pre-operative image captured by the operation target object 70 is compared with the post-operative image captured by the operation target object 70, thereby recognizing an identification means 60 which is not displayed on the screen, thereby enabling the target action component 72 to be identified. Since the identification number 60 of the identification means 60 cannot be retrieved from the system, the target action component 72 can be identified. Using the identification means described above, the target action component can be automatically recognized in the captured image and the operational data recorded.

FIG. 15 is an illustrative diagram of the means for identifying the deviation. The misalignment identifier is mounted on the operation target object 70 and the tool 40. The target action component 72 is provided with a number of target action components 72a along with the target action components 72 on the operation object 70 as a number of target action components 72. 60b is mounted at a position (in the embodiment of the present invention on the upper end of a wrench head) closest to the identification means 60a which is attached to the operation target object 70 during operation such that the identification means 60b is shown in a captured image.

The tightening operation using the deviation identification tools described above is performed as follows. When the operation target object 70 is inspected, the associated device (operation object) is filmed by the image capture terminal 30 connected to the work terminal 20. After verifying that the operation target 70 and the identification means 60a are displayed on the preview screen, press the capture button to perform the recording. Using the identification means 60a, the position information of the target action component 72 can be identified in the captured image. Thereafter, a tightening action is performed on the target action component 72. As the identification means 60a is affixed to the target action component for which the operation is to be performed, it is positioned closest to the identification means 60b attached to the tool 40. The post-operation image of the target action component 72 identifies the identification means 60a of the target action component 72. closest to the identification means 60b in the tool and identifying the target action component 72 for which the action has been performed. Using the identification tools described above, the target action component of the captured image can be automatically recognized and operational data recorded.

The identification means shown in Figs. 14 and 15, a plurality of target action components may optimally identify the target action component for which the action is being performed, and one-dimensional, two-dimensional, or similar codes may be applied.
