<System configuration example>
FIG. 1 is an explanatory diagram illustrating a system configuration example of the management system. The management system 100 has a management device 101 and a polyhedron 102. The management device 101 is a computer that analyzes data from the polyhedron 102 and manages the work performed by the worker. The management device 101 can access the polyhedron DB 103 and the work content DB 104. The polyhedron DB 103 is a database that stores, for each polyhedron 102, the correspondence between the surface constituting the polyhedron 102 and the value of attribute information (for example, an operator, a work number, and a production number) related to the work content. The work content DB 104 is a database that stores analysis results of data from the polyhedron 102 in chronological order.

  The polyhedron 102 is a device used by an operator. The polyhedron 102 is placed by a worker in a predetermined installation area Ai (i, n is an integer of 1 or more and 1 ≦ i ≦ n). The polyhedron 102 is an object that is configured by four or more polygonal surfaces, and whose installation surface is parallel to the opposite surface. For example, tetrahedron, hexahedron, octahedron, decahedron, and dodecahedron can be mentioned. Each surface is preferably a regular polygon. In addition, the card including the front and back sides is also a hexahedron. In this embodiment, for convenience, the shape of the polyhedron 102 will be described as a regular hexahedron.

  The polyhedron 102 transmits internal data to the management device 101 regularly or irregularly. Specifically, for example, the polyhedron 102 transmits internal data to the management device 101 via a network device Di such as a router or a switch. The network device Di measures the signal strength of the data received from the polyhedron 102 and transmits the measured data strength to the management device 101 together with the data.

  The polyhedron 102 is used for each installation area Ai. In this example, three polyhedrons 102 are used for each installation area. The number of polyhedrons 102 used may be one, two or four or more. Each of the three polyhedrons 102A to 102C displays a different attribute on the surface.

<Configuration example of polyhedron 102>
FIG. 2 is an explanatory diagram illustrating a configuration example of the polyhedron 102. FIG. 2A is a block diagram illustrating an example of a hardware configuration of the polyhedron 102, and FIG. 2B is a developed view of the polyhedron 102. 2A, the polyhedron 102 includes a processor 201, a memory 202, an acceleration sensor 203, a communication IF 204, and a bus 205 connecting these. The processor 201 controls the polyhedron 102. The memory 202 is a work area of the processor 201. The memory 202 serving as a storage unit is a non-temporary or temporary recording medium that stores data such as various programs and a polyhedron ID 220. As the memory 202, for example, there is a flash memory 202.

  The polyhedron ID 220 is identification information that uniquely identifies the polyhedron 102. Specifically, for example, the polyhedron ID 220 is identification information that uniquely specifies what attribute the polyhedron 102 indicates and what value range the attribute has. For example, when the polyhedron 102 has an attribute: worker, the polyhedron ID 220 is “Sa” including the attribute: identification information S of the worker. Instead of the polyhedron ID 220, a device-specific ID such as a MAC (Media Access Control) address of the polyhedron 102 may be used. The device-specific ID is also identification information for uniquely identifying the polyhedron 102.

  In this case, the management apparatus 101 has a table in which the MAC address and the polyhedron ID 220 are associated, and converts the received MAC address into the corresponding polyhedron ID 220. When a device-specific ID such as a MAC address is used, the corresponding polyhedron ID 220 can be changed in the management device 101. In the present embodiment, for convenience of explanation, the description will be made assuming that the polyhedron ID 220 is stored in the memory 202.

  The acceleration sensor 203 is a detection unit that detects the posture of the polyhedron 102. The acceleration sensor 203 is, for example, a three-axis sensor, and outputs an X-axis value x, a Y-axis value y, and a Z-axis value z as attitude information. Here, the Z + axis of the Z axis indicates the vertical direction, that is, the direction of gravity. The X axis is orthogonal to the Y axis and the Z axis, and the Y axis is orthogonal to the X axis and the Z axis. The Z + axis is parallel to the outward normal of a predetermined reference plane of the polyhedron 102. The orientation of the polyhedron 102 is determined based on the outward normal from this reference plane. For example, when the posture information is (x, y, z) = (0, 0, 1), it is assumed that the orientation of the polyhedron 102 matches the outward normal of the reference plane. Not only the acceleration sensor 203 but also a magnetic sensor may be used as the detection unit.

  The communication IF 204 transmits data to the network device Di. Specifically, for example, the communication IF 204 transmits the polyhedron ID 220 in the memory 202 and the posture information detected by the acceleration sensor 203 as the polyhedron information of the polyhedron 102. Communication IF 204 transmits polyhedral information at predetermined time intervals (for example, every one minute). The transmitted polyhedron information is received by the network device Di. Although not shown, a switch for turning on or off the transmission of data from the communication IF 204 may be provided in the polyhedron 102.

  In the developed view of (B), a developed view of three types of polyhedrons 102 is shown. The character string displayed on each surface of the polyhedron 102 may be physically displayed on the surface by painting, sticking a seal, engraving, or, for example, by an electronic display such as a liquid crystal, an LED, and an organic EL. It may be displayed electronically on a surface.

  The first polyhedron 102A is a polyhedron 102 whose attribute is set to “worker”. In FIG. 2, the range of the value of the attribute is “worker A”. The character string “worker A” is displayed on five of the six faces of the first polyhedron 102A. The character string “Worker A END” is displayed on the remaining one surface (surface 102Au). The character string “Worker A END” indicates a state where the worker A is not working. Note that the Z + axis is parallel to the outward normal of the surface 102Au on which the character string “Worker A END” is displayed. When the surface 102As of the first polyhedron 102A is placed so as to be installed, the upper surface of the first polyhedron 102A becomes the surface 102Au, which indicates a state where the worker A is not working. On the other hand, in the case where the surface other than the surface 102As of the first polyhedron 102 is placed so as to be installed, the upper surface of the first polyhedron 102A becomes the surface on which the character string “operator A” is displayed, and the worker A The state which is doing.

  Further, one worker may share one first polyhedron 102A. For example, when five workers A to E share one first polyhedron 102A, five of the six faces of the first polyhedron 102A have character strings “worker A” to “worker "E" is displayed. On the remaining one surface (surface 102Au), a character string “workers A to E END” (a state in which none of the workers A to E is working) is displayed.

  The second polyhedron 102B is a polyhedron 102 whose attribute is set to “work number”. The work number is identification information for uniquely specifying the work. In FIG. 2, the value range of the attribute is “P001 to P005”. “P” indicates the attribute of the work number. Character strings “P001” to “P005” are displayed on five of the six surfaces of the second polyhedron 102B, respectively. A character string “N / A” is displayed on the remaining one surface (surface 102Bu). The character string “N / A” means “Not Available”. That is, it indicates that the work of any of the work numbers P001 to P005 is not performed. Note that the Z + axis is parallel to the outward normal of the surface 102Bu on which the character string “N / A” is displayed. When the surface 102Bs of the second polyhedron 102B is placed so as to be installed, the upper surface of the second polyhedron 102B becomes the surface 102Bu, which indicates a state in which any of the operation numbers P001 to P005 is not performed. On the other hand, when the surface on which the work number of any of the character strings “P001” to “P005” is displayed is the top surface, the work of the work number displayed on the top surface is being performed. Is shown.

  Note that, in the second polyhedron 102B of FIG. 2, an example has been described in which work numbers P001 to P005 are displayed on each surface, but work numbers P006 and thereafter are similarly displayed on another second polyhedron 102B. .

  The third polyhedron 102C is a polyhedron 102 whose attribute is set to “serial number”. The production number is identification information for uniquely specifying a product (including a finished product (also referred to as a product), an intermediate product, and parts). In FIG. 2, the value range of the attribute is “N001 to N005”. “N” indicates the attribute of the serial number. Character strings “N001” to “N005” are displayed on five of the six surfaces of the third polyhedron 102C, respectively. A character string “N / A” is displayed on the remaining one surface (surface 102Cu). The character string “N / A” means “Not Available”. That is, it indicates that the products with any of the production numbers N001 to P005 are not work targets. Note that the Z + axis is parallel to the outward normal of the surface 102Cu on which the character string “N / A” is displayed. When the surface 102Cs of the third polyhedron 102C is placed so as to be installed, the upper surface of the third polyhedron 102C becomes the surface 102Cu, which indicates that the products with any of the serial numbers N001 to N005 are not work targets. On the other hand, when the product is placed such that the surface on which any one of the character strings “N001” to “N005” is displayed is the upper surface, the product having the serial number displayed on the upper surface is the work target. Indicates that

  Note that, in the third polyhedron 102C of FIG. 2, an example has been described in which serial numbers N001 to N005 are displayed on each surface. .

<Example of DB storage contents>
FIG. 3 is an explanatory diagram showing an example of the storage contents of the polyhedral DB 103 shown in FIG. The polyhedron DB 103 stores a polyhedron table 300 for each polyhedron 102. The polyhedron table 300 is a table having a polyhedron ID 220 and associating a surface ID with an attribute value. Specifically, for example, the first polyhedron table 300A is a polyhedron table 300 of attribute: worker, the second polyhedron table 300B is a polyhedron table 300 of attribute: work number, and the third polyhedron table 300C is Attribute: The worker's polyhedron table 300.

  The first polyhedron table 300A is a table that has a polyhedron ID 220: Sa including identification information S indicating an operator as an attribute, and associates a surface ID 301 with an operator number 302 as an attribute value. The surface ID 301 is identification information for uniquely specifying the surface of the polyhedron 102. The worker number 302 is identification information for uniquely identifying the worker. In the first polyhedron table 300A, the values “1” to “5” of the surface ID 301 are associated with the operator number “A”, and the value “6” of the surface ID 301 and the operator number “A END” (A state in which the worker A is not working).

  Since the first polyhedron table 300A is a table for specifying whether or not a specific worker is working, the other workers (for example, workers B, C, D,...) Another first polyhedron table 300A is prepared. In this case, a different polyhedron ID 220 is set for each first polyhedron table 300A. Further, one worker may share one first polyhedron 102A. For example, when one worker 102 shares one first polyhedron 102A, the value “1” of the surface ID 301 is the value “A” of the worker number 302, and the value “2” of the surface ID 301 is the worker. The value “B” of the number 302, the value “3” of the surface ID 301 is the value “C” of the worker number 302, the value “4” of the surface ID 301 is the value “D” of the worker number 302, and the value “5” of the surface ID 301 "Is the value" E "of the worker number 302, the value" 6 "of the surface ID 301 is the value" A-E END "of the worker number 302 (state in which none of the workers A-E is working), And it is sufficient.

  The second polyhedron table 300B is a table that has a polyhedron ID 220: Pa including identification information P indicating a work number as an attribute, and associates a surface ID 301 with a worker number 302 as an attribute value. The work number 303 is identification information for uniquely specifying a work. In the second polyhedron table 300B, the values “1” to “5” of the surface ID 301 are associated with the operation numbers “P001” to “P005”, and the value “6” of the surface ID 301 and the operation number “N” / A "(Not Available). When there are a plurality of second polyhedrons 102B, a second polyhedron table 300B is prepared for each second polyhedron 102B. In this case, a different polyhedron ID 220 is set for each second polyhedron table 300B.

  The third polyhedron table 300C is a table that has a polyhedron ID 220: Na including identification information N indicating a production number as an attribute, and associates a surface ID 301 with a production number 304 as an attribute value. The production number 304 is identification information for uniquely specifying a product. In the third polyhedron table 300C, the values “1” to “5” of the surface ID 301 are associated with the serial numbers “N001” to “N005”, and the value “6” of the surface ID 301 and the serial number “N” / A "(Not Available). When there are a plurality of third polyhedrons 102C, a third polyhedron table 300C is prepared for each third polyhedron 102C. In this case, a different polyhedron ID 220 is set for each third polyhedron table 300C.

  Next, an example of contents stored in the work content DB 104 will be described with reference to FIGS. The work content DB 104 is a database that stores data on who worked on what product and when. The operations are roughly classified into three types of production systems, a line production system, a cell production system, and a line × cell production system.

  The line production method is a production method in which an operator is arranged on a production line and performs a work on a part moving on the production line or attaching another part. Basically, the same worker always performs the work with the same work number on the moving parts, so that the work number does not change and the manufacturing number of the work object changes.

  The cell production system is a production system in which the same operator performs a series of operations including a plurality of operation numbers on components arranged at fixed locations. When looking at the same worker for a certain period, the production number of the work target does not change, and the work number changes sequentially.

  The line × cell production system is a system in which the line production system and the cell production system are multiplied. The operator carries out the work of a plurality of work numbers at the same time for parts having a plurality of manufacture numbers. When these operations are completed, the operations of the same plurality of work numbers are performed on the parts having the next plurality of serial numbers at the same time. Therefore, looking at the same worker, both the work number and the serial number change sequentially.

  FIG. 4 is an explanatory diagram showing an example of the stored contents of the work content DB 104 regarding the line production method. FIG. 5 is an explanatory diagram showing an example of the contents of the work content DB 104 regarding the cell production method. FIG. 6 is an explanatory diagram showing an example of the storage contents of the work content DB 104 regarding the line × cell production method.

  The work content DB 104 is a set of records in which an operator number 302, a work number 303, a manufacturing number 304, and a work time 400 are associated with each other and each value is combined. The work time 400 is the time at which the worker specified by the worker number 302 constituting the record performed the work specified by the work number 303 on the product specified by the manufacturing number 304. Specifically, for example, the work time 400 may be a time stamp generated by the polyhedron 102 and included in the polyhedron information when the polyhedron 102 transmits the polyhedron information, and when the network device Di receives or transmits the polyhedron information. Or a time stamp generated when the management apparatus 101 receives the polyhedron information.

<Example of work management using polyhedron 102>
Next, a work management example of a line production method using the polyhedron 102 will be described with reference to FIGS. In the following example, the worker places the polyhedron 102, but may be a manager instead of the worker.

  FIG. 7 is an explanatory diagram showing an example of a work management of the line production method using the polyhedron 102. It is assumed that the polyhedron 102 shown in FIG. 7 exists within the range of the network device Di.

  In step S701, the workers A and B start the operation of the operation number P003 on the product of the production number N001 at, for example, 8:31. In this case, the worker A places his / her first polyhedron 102A (hereinafter, the first polyhedron 102AA) such that the character string “Worker A” is on the top side, and the worker B has his / her first polyhedron 102A. The polyhedron 102A (hereinafter, the first polyhedron 102AB) is placed so that the character string "Worker B" faces upward. In addition, the worker A or the worker B places the second polyhedron 102B such that the character string “P003” faces up, and places the third polyhedron 102C so that the character string “N001” faces up. Place.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management device 101 specifies the upper surface of the polyhedron 102 from the posture information from the acceleration sensor 203 in the polyhedron information. Then, the records 400-1 to 400-2 are registered in the work content DB 104 shown in FIG. 4 together with the work time 400 (8:31). Since the polyhedron 102 transmits the polyhedron information at predetermined time intervals (for example, every one minute), the management device 101 stores the record 400 in the work content DB 104 shown in FIG. 4 together with the work time 400 (8:32). -3 to 400-4 are registered. Thus, records are accumulated in the work content DB 104 at predetermined time intervals.

  In step S702, it is assumed that the worker A temporarily leaves the work P003 at 10:03, for example, by attending a meeting or taking a break. In this case, the worker A places the first polyhedron 102AA such that the character string “Worker A END” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management device 101 specifies the upper surface of the polyhedron 102 from the posture information from the acceleration sensor 203 in the polyhedron information. Then, the management apparatus 101 registers the records 400-5 to 400-6 together with the work time 400 (10:03) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals.

  In step S703, the worker C joins the work P003 at 10:03, for example, as a substitute for the worker A. In this case, the worker C places his or her first polyhedron 102A or lower and the first polyhedron 102AC) such that the character string “worker C” is on the upper surface.

  The first polyhedron 102AC transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the first polyhedron 102AC as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker corresponding to the surface ID 301 of the observation surface. The number 302, the operation number 303, and the production number 304 are specified. Then, the management apparatus 101 registers the record 400-7 together with the work time 400 (10:03) in the work content DB 104 shown in FIG.

  In step S704, it is assumed that the worker A returns to the work P003 at, for example, 10:30, and the worker C leaves the work P003. In this case, the worker A places the first polyhedron 102AA such that the character string "worker A" is on the upper surface. Further, the worker C takes the first polyhedron 102AC out of the service area of the network device Di and leaves the work P003. Alternatively, the worker C turns off the communication IF of the first polyhedron 102AC.

  Each polyhedron 102 (excluding the first polyhedron 102AC) transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, the management apparatus 101 registers the records 400-8 to 400-9 together with the work time 400 (10:30) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals. Since the management apparatus 101 does not receive the polyhedron information from the first polyhedron 102AC, the record with the operator number “C” is not registered.

  In step S705, the workers A and B, for example, end the operation of the operation number P3 on the product of the production number N001, and start the operation of the operation number P3 on the product of the production number N002 at 10:50. In this case, the worker A or the worker B places the third polyhedron 102C such that the character string “N002” is on the upper surface.

  Each polyhedron 102 (excluding the first polyhedron 102AC) transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management device 101 specifies the upper surface of the polyhedron 102 from the posture information from the acceleration sensor 203 in the polyhedron information. Then, records 400-10 to 400-11 are registered together with the work time 400 (10:30) in the work content DB 104 shown in FIG. Thus, records are accumulated in the work content DB 104 at predetermined time intervals.

  In the case of the line production system, the operation of the same operation number is performed on the products of the serial number sequentially transported to the worker by the belt conveyor. Therefore, the operator sequentially changes the surface of the third polyhedron 102C on which the serial number is mainly displayed. As described above, the work content can be stored in the work content DB 104 by a simple operation of changing the upper surface of the polyhedron 102, so that the burden on the worker can be reduced, and an artificial management error of the work content can be suppressed. Can be.

  It should be noted that the production number (the third polyhedron 102C) is not used, and a tag for transmitting its own production number is hung on the product of the production number (or the contents thereof), and the tag is read by the network device Di. Good. This eliminates the need for the operator to appropriately change the setting of the third polyhedron 102C. Therefore, while reducing the burden on the worker, there is no human operation error (for example, forgetting to change the installation, mistake in the installation change) by the worker, and the management accuracy of the work man-hour management can be improved.

  Next, an example of work management of a cell production method using the polyhedron 102 will be described with reference to FIGS.

  FIG. 8 is an explanatory diagram showing an example of a work management of a cell production method using the polyhedron 102. It is assumed that the polyhedron 102 shown in FIG. 8 exists within the range of the network device Di.

  In step S801, the worker E starts the operation of the operation number P011 on the product of the production number N060, for example, at 9:00. In this case, the worker E places his / her first polyhedron 102A (hereinafter, the first polyhedron 102AE) such that the character string “Worker E” is on the upper surface. In addition, the worker E places the second polyhedron 102B such that the character string “P011” is on the upper surface, and places the third polyhedron 102C such that the character string “N060” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, the record 500-1 is registered with the work time 400 (9:00) in the work content DB 104 shown in FIG. Since the polyhedron 102 transmits the polyhedron information at predetermined time intervals (for example, every one minute), the management device 101 stores the record 400 in the work content DB 104 shown in FIG. 5 together with the work time 400 (9:01). -2 is registered, and a record 400-3 is registered together with the work time 400 (9:02). Thus, records are accumulated in the work content DB 104 at predetermined time intervals.

  In step S802, the worker E finishes the work with the work number P011 and starts the work with the work number P012 at, for example, 10:35. In this case, the worker E places the second polyhedron 102B such that the character string “P012” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, the record 500-4 is registered with the work time 400 (10:35) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals.

  In step S803, for example, at 11:20, the worker E finishes the operation of the operation number P012 for the product of the serial number 060 and starts the operation of the operation number P011 for the next product of the serial number 061. I do. In this case, the worker E places the second polyhedron 102B so that the character string “P011” is on the upper surface, and places the third polyhedron 102C so that the character string “N061” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, a record 500-5 is registered with the work time 400 (11:20) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals.

  In the case of the cell production method, since a series of work numbers are performed on a product having a manufacture number to be worked, the second polyhedron 102B is mainly changed sequentially. As described above, the work content can be stored in the work content DB 104 by a simple operation of changing the upper surface of the polyhedron 102, so that the burden on the worker can be reduced, and an artificial management error of the work content can be suppressed. Can be.

  It should be noted that the production number (the third polyhedron 102C) is not used, and a tag for transmitting its own production number is hung on the product of the production number (or the contents thereof), and the tag is read by the network device Di. Good. This eliminates the need for the operator to appropriately change the setting of the third polyhedron 102C. Therefore, while reducing the burden on the worker, there is no human operation error (for example, forgetting to change the installation, mistake in the installation change) by the worker, and the management accuracy of the work man-hour management can be improved.

  Next, with reference to FIGS. 9 and 6, an example of the work management of the line × cell production system using the polyhedron 102 will be described.

  FIG. 9 is an explanatory diagram showing an example of the work management of the line × cell production method using the polyhedron 102. It is assumed that the polyhedron 102 shown in FIG. 9 exists within the range of the network device Di.

  In step S901, the worker F starts the operation of the operation number P070 for each product of the serial numbers N220 and N221, for example, at 8:32. In this case, the worker F places his / her first polyhedron 102A (hereinafter, the first polyhedron 102AF) such that the character string “Worker F” is on the upper surface. Further, the worker F places the second polyhedron 102B such that the character string “P070” is on the upper surface. Further, the worker F places one third polyhedron 102C (hereinafter, third polyhedron 102C1) of the two third polyhedrons 102C such that the character string “N220” is on the upper surface, and the other third polyhedron 102C1. The polyhedron 102C (hereinafter, the third polyhedron 102C2) is placed so that the character string “N221” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, records 600-1 to 600-2 are registered together with the work time 400 (8:32) in the work content DB 104 shown in FIG. The polyhedron 102 transmits records 600-3 to 600-4 in the work content DB 104 shown in FIG. 6 and in the work content DB 104 at predetermined time intervals in order to transmit the polyhedron information at predetermined time intervals (for example, every one minute). Is accumulated.

  In step S902, the worker F finishes the work of the work number P070 at 9:42 and starts the work of the work number P071. In this case, the worker F places the second polyhedron 102B such that the character string “P071” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, records 600-5 to 600-6 are registered together with the work time 400 (9:42) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals.

  In step S903, since the worker F has finished the work P071 at, for example, 10:22, it is assumed that the worker F temporarily leaves the work P071 by taking a break. In this case, the worker F places the first polyhedron 102AF such that the character string “worker F END” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, the management apparatus 101 registers the records 600-7 to 600-8 together with the work time 400 (10:22) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals.

  In step S904, it is assumed that the worker F returns to, for example, 10:35, and starts the operation P071 for each product of the next serial numbers N222 and N223. In this case, the worker F places the first polyhedron 102AF such that the character string “worker A” is on the upper surface. Further, the worker F places the second polyhedron 102B such that the character string “P070” is on the upper surface. Further, the worker F places the third polyhedron 102C1 such that the character string “N222” is on the upper surface, and places the third polyhedron 102C2 such that the character string “N223” is on the upper surface.

  Each polyhedron 102 transmits the polyhedron information to the management device 101 via the network device Di. Thereby, the management apparatus 101 specifies the upper surface of the polyhedron 102 as the observation surface from the posture information from the acceleration sensor 203 in the polyhedron information, refers to the polyhedron table 300, and checks the worker number 302 corresponding to the surface ID 301 of the observation surface. , Work number 303, and production number 304 are specified. Then, the management apparatus 101 registers the records 600-9 to 600-10 together with the work time 400 (10:35) in the work content DB 104 shown in FIG. Thereafter, records are accumulated in the work content DB 104 at predetermined time intervals.

  Not only in the line × cell production method, but also in the case of performing operations on products having a plurality of serial numbers simultaneously and in parallel, a plurality of third polyhedrons 102C are prepared and installed at the same time. As a result, work content management for each production number can be performed. Similarly, when performing the operations of a plurality of operation numbers in parallel, a plurality of second polyhedrons 102B are prepared and installed at the same time. Thereby, work content management for each work number can be performed.

<Configuration Example of Management Device 101>
FIG. 10 is a block diagram illustrating an example of a hardware configuration of the management apparatus 101. The management apparatus 101 has a processor 1001, a storage device 1002, an input device 1003, an output device 1004, and a communication interface (communication IF 1005). The processor 1001, the storage device 1002, the input device 1003, the output device 1004, and the communication IF 1005 are connected by a bus. The processor 1001 controls the management device 101. The storage device 1002 is a work area of the processor 1001. The storage device 1002 is a non-temporary or temporary recording medium for storing various programs and data. Examples of the storage device 1002 include a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), and a flash memory. The input device 1003 inputs data. Examples of the input device 1003 include a keyboard, a mouse, a touch panel, a numeric keypad, and a scanner. The output device 1004 outputs data. The output device 1004 includes, for example, a display and a printer. The communication IF 1005 connects to the network device Di and transmits and receives data.

  FIG. 11 is a block diagram illustrating an example of a functional configuration of the management apparatus 101 according to the first embodiment. The management apparatus 101 includes a polyhedral DB 103, a work content DB 104, a specifying unit 1101, a determining unit 1102, a selecting unit 1103, an output unit 1104, and a collecting unit 1105. The polyhedron DB 103 and the work content DB 104 are specifically realized by, for example, the storage device shown in FIG. Note that the polyhedral DB 103 and / or the work content DB 104 may be provided in another storage device outside the management apparatus 101 as long as the processor 1001 can access it. The specifying unit 1101, the selection unit 1103, the determination unit 1102, the output unit 1104, and the collection unit 1105 specifically cause the processor 1001 to execute a program stored in the storage device 1002 illustrated in FIG. It is a function realized by.

  The specifying unit 1101 specifies attribute information related to work content displayed on a specific surface of the polyhedron 102 in a state where the polyhedron 102 is placed, based on the posture information from the communication IF 1005. The specific surface is a surface on which information (character string) for identifying the worker's work is displayed while the polyhedron 102 is placed (hereinafter referred to as an “observation surface”). "). In the above example, the observation surface is the upper surface of the polyhedron 102 when the polyhedron 102 is placed. Note that the observation surface is not limited to the upper surface, but may be one side surface. Which plane is the observation plane is uniquely determined by the posture information, that is, the orientation of the polyhedron 102.

  Specifically, for example, the polyhedron 102 defines an outward normal from a certain reference plane as a vertical direction. The specifying unit 1101 detects an inclination between the orientation of the polyhedron 102 specified by the posture information of the polyhedron 102 and an outward normal from the reference plane, and determines an installation surface on which the polyhedron 102 is to be placed according to the inclination. Identify.

  For example, taking the second polyhedron 102B as an example, the reference plane is the plane 102Bu. When the posture information is (x, y, z) = (0, 0, 1), the direction of the polyhedron 102 specified by the posture information matches the direction of the outward normal of the surface 1402Bu. Therefore, in this case, since there is no inclination, the specifying unit 1101 specifies the surface 102Bu as the installation surface, and specifies the surface 102Bs on the opposite side as the upper surface of the polyhedron 102. Conversely, when the posture information is (x, y, z) = (0, 0, -1), the specifying unit 1101 specifies the surface 102Bs as the installation surface, and sets the opposite surface 102Bu to the second polyhedron. 102B.

  Further, for example, the outward normal of the display surface of “P003” is set to (x, y, z) = (1, 0, 0). When the received posture information is (x, y, z) = (1, 0, 0), the installation surface of the second polyhedron 102B is the display surface of “P003”. Therefore, the specifying unit 1101 specifies the display surface of “P004” on the opposite side as the upper surface of the second polyhedron 102B. Conversely, when the posture information is (x, y, z) = (-1, 0, 0), the specifying unit 1101 specifies the display surface of “P004” as the installation surface, and the opposite side “ The display surface of “P003” is specified as the upper surface of the second polyhedron 102B.

  For example, the outward normal of the display surface of “P002” is (x, y, z) = (0, 1, 0). When the received attitude information is (x, y, z) = (0, 1, 0), the installation surface of the second polyhedron 102B is the display surface of “P002”. Therefore, the specifying unit 1101 specifies the display surface of “P005” on the opposite side as the upper surface of the second polyhedron 102B. Conversely, when the posture information is (x, y, z) = (0, −1, 0), the specifying unit 1101 specifies the display surface of “P005” as the installation surface, and sets “P005” on the opposite side. The upper surface of the second polyhedron 102B that is the surface of “P002” is specified as the observation surface.

  Then, when the observation surface is determined, the identification unit 1101 refers to the polyhedron table 300 and identifies the attribute information corresponding to the surface ID 301 of the observation surface. Specifically, for example, in the case of the second polyhedron 102B, when the polyhedron ID 220 is “Pa” and the plane ID 301 of the observation surface is “1”, the identification unit 1101 assigns “P001” of the work number 303 to the attribute. Identify as information. Similarly, the specifying unit 1101 specifies the observation surface and the attribute information for the first polyhedron 102 and the third polyhedron 102.

  When a plurality of combinations of the posture information and the signal strength are received within the same period, the selection unit 1103 selects a combination to be a management target candidate from the plurality of combinations based on the signal strength included in each combination. I do. The same period is a certain time interval (for example, one minute). Although the polyhedron 102 transmits the polyhedron information, it may be received by a network device Di in an adjacent area in addition to the network device Di in the service area. In this case, when receiving the polyhedron information including the same polyhedron ID 220 and the signal strength from different network devices Di, the selection unit 1103 selects the polyhedron information with the higher signal strength as a candidate for management. In addition, when the polyhedron information is received and the signal strength is equal to or greater than the threshold, the selection unit 1103 may select the polyhedron information as a management target candidate.

  In this case, the specifying unit 1101 specifies the observation plane and the attribute information as described above, based on the posture information included in the selected polyhedron information. As a result, the polyhedral information having the lower signal strength can be excluded, and the management of the work content can be improved.

  Note that the selection unit 1103 receives a plurality of combinations of the polyhedron information including the identification information (polyhedron ID) of the polyhedron 102 and the posture information and the signal strength of the polyhedron 102 from the polyhedron 102 detected by the network device Di. Also, as described above, a combination to be a management target candidate is selected from a plurality of combinations based on the signal strength included in each combination.

  The determining unit 1102 determines whether the combination of identification information included in the polyhedron information from each of the polyhedrons 102 from the communication IF 1005 is a combination to be managed. The combination to be managed is set in advance. In the case of this example, the combination of identification information to be managed is a combination of identification information S, P, and N indicating an attribute. For example, when the identification unit 1102 receives the identification information Sa of the first polyhedron 102, the identification information Pa of the second polyhedron 102, and the identification information Na of the third polyhedron 102, the determination unit 1102 determines that the combination is a management target, that is, It is determined that a plurality of pieces of polyhedron information have been received. If any one of the identification information is missing, it is not managed.

  In this case, when it is determined that the object is to be managed, the specifying unit 1101 specifies the observation plane and the attribute information for each polyhedron 102 based on the posture information included in each piece of polyhedron information, as described above. Thereby, the lack of the work content can be suppressed, and the accuracy of management of the work content can be improved.

  The output unit 1104 outputs attribute information on the work content specified by the specifying unit 1101. The output unit 1104 outputs the attribute information in association with the work time at the time of output. The output unit 1104 specifically transmits, for example, the attribute information and the work time to an external device having the work content DB 104, displays the work information on a display as an example of the output device 1004, and outputs the work information in the storage device 1002. It is stored in the content DB 104.

  The collection unit 1105 collects the remaining attribute information from the work content DB 104 based on specific attribute information among the plurality of attribute information. Specifically, for example, the collection unit 1105 searches the work content DB 104 by using a specific attribute information as a key by an operation from the user, and collects remaining attribute information related to the specific attribute information. For example, when the worker number: A is used as the key as the specific attribute information, the work number and the production number associated with the worker number: A are collected.

<Example of management processing procedure>
FIG. 12 is an explanatory diagram illustrating an example of a management processing procedure performed by the management system 100. The polyhedron 102 transmits polyhedron information including a polyhedron ID 220 and posture information (step S1201). The network device Di receives the transmitted polyhedron information (step S1202). Upon receiving the polyhedron information, the network device Di measures the signal strength (step S1202). The network device Di transmits the polyhedron information and the signal strength to the management device 101 (step S1203).

  The management device 101 selects polyhedron information to be a management target candidate by referring to the signal strength by the selection unit 1103 (step S1204). Next, when the management device 101 receives a plurality of pieces of polyhedron information, the determination unit 1102 determines whether the combination of the polyhedron ID 220 in each piece of polyhedron information is a combination to be managed (step S1205). .

  Next, the management apparatus 101 specifies an observation surface by the specifying unit 1101 (step S1206), and specifies attribute information relating to work content corresponding to the observation surface with reference to the polyhedron table 300 (step S1207). Then, the management apparatus 101 causes the output unit 1104 to store the specified attribute information in the work content DB 104 (Step S1208).

<Example of data collection procedure>
FIG. 13 is a flowchart illustrating an example of a data collection processing procedure performed by the collection unit 1105. The management apparatus 101 accepts the designation of the collection period by the operation of the administrator (step S1301). The management apparatus 101 acquires a record of the work time 400 included in the specified collection period from the work content DB 104 with reference to the work time 400 (step S1302). The management apparatus 101 divides the collected record group at a predetermined collection interval (for example, 5 minutes) (step S1303). The period divided by the collection interval is referred to as a collection section.

  The management apparatus 101 determines whether there is an unselected collection section (step S1304). When there is an unselected collection section (step S1304: Yes), the management apparatus 101 selects an unselected collection section (step S1305). The management apparatus 101 determines whether there is a record in which the work number and the manufacturing number for the same worker number are different in the selected collection section (step S1306). For example, if the record of the work number P001 and the serial number N001 and the record of the work number P001 and the serial number N002 exist for the worker number A, they are different records.

  If there is a different record (step S1306: Yes), the management apparatus 101 counts the number of records for each combination of the work number and the production number indicated by the different record in the selected counting section (step S1307). The management apparatus 101 determines whether or not there are a plurality of combinations having the largest number of records (step S1308). If there are a plurality of records (step S1308: Yes), the management device 101 apportions the selected tabulation section with the maximum number of combinations of records, and determines the work time and work contents of each combination (step S1309). Then, the process returns to step S1304.

  On the other hand, in Step S1308, when there are not a plurality of combinations with the largest number of records (Step S1308: No), the management apparatus 101 determines the combination with the largest number of records as the work content of the selected collection section (Step S1310). Then, the process returns to step S1304.

  On the other hand, when there is no different record in step S1306 (step S1306: No), the management device 101 determines the combination as the work content of the selected collection section (step S1311). Then, the process returns to step S1304.

  On the other hand, in step S1304, when there is no unselected aggregation section (step S1304: No), the management apparatus 101 outputs a collection result (step S1312).

  FIG. 14 is an explanatory diagram of an example of the output screen of the collection result according to the first embodiment. When the administrator specifies collection conditions such as a collection period from the input device 1003 of the management apparatus 101, the collection unit 1105 collects records from the work content DB 104, and the output device 1004 displays the collection result on the output screen 1400. FIG. 14 shows an example in which the collection conditions are “worker Taro Hita, work date: June 1, 2016”. The work contents of the designated worker for the day are displayed together with the start and end times. A correction button 1401 may be provided so that the administrator can correct the displayed data, or an approval button 1402 may be provided so that the administrator or superior can approve the displayed data. In addition, a collection period change button 1403 may be provided so that a work man-hour table for an arbitrary period such as a weekly unit, a monthly unit, or the like from the display of one day can be viewed. Further, a condition change button 1404 for changing the collection condition may be provided.

  As described above, according to the first embodiment, since the work content can be stored in the work content DB 104 by a simple operation of changing the observation surface of the polyhedron 102, the burden on the worker can be reduced, and Management error can be suppressed.

  Also, by referring to the signal strength of the polyhedron information, it is possible to exclude polyhedron information having a low signal strength from the polyhedron 102 outside the work area Ai. Therefore, it is possible to improve the management accuracy of the work content.

  In addition, by performing a match determination between the combination of the polyhedron ID 220 of the plurality of pieces of polyhedron information and the combination of the management target, it is possible to exclude combinations that are not to be managed. Therefore, it is possible to improve the management accuracy of the work content.

  The second embodiment is an example in which the collection result shown in the first embodiment is compared with the work process table in the same period as the collection period of the collection result. The second embodiment focuses on the differences from the first embodiment, and a description of the same parts and processes as those of the first embodiment will be omitted.

  FIG. 15 is a block diagram illustrating a functional configuration example of the management apparatus 101 according to the second embodiment. The management apparatus 101 includes a work process table DB 1501, a collection result DB 1502, and a collation unit 1503. The work process table DB 1501 and the collection result DB 1502 are specifically realized, for example, specifically, for example, by the storage device 1002 shown in FIG. The work schedule DB 1501 and / or the collection result DB 1502 may be provided in another storage device 1002 outside the management apparatus 101 as long as the processor 1001 can access the work process table DB 1501 and / or the collection result DB 1502. The collation unit 1503 is, specifically, a function realized by, for example, causing the processor 1001 to execute a program stored in the storage device 1002 illustrated in FIG.

  The work schedule DB 1501 stores work schedule information. The work schedule information is information obtained by converting a work schedule set in advance into data.

  FIG. 16 is an explanatory diagram showing an example of work process table information stored in the work process table DB 1501. The work process table information 1600 is information in which a worker number 1601, a work number 1602, a production number 1603, a start time 1604, and an end time 1605 are tabulated. The worker number 1601 is identification information for uniquely identifying a worker. The work number 1602 is identification information for uniquely specifying a work. The production number 1603 is identification information for uniquely specifying a product. The start time 1604 is a time at which the work specified by the record is started. The end time 1605 is a time at which the work specified by the record ends. The record of the work process schedule information 1600 defines when (from the start time 1604 to the end time 1605) who works on what product and what work.

  Returning to FIG. 15, the collection result DB 1502 stores the collection results output from the collection unit 1105 and processed by the collation unit 1503. The collection result DB 1502 will be described later.

  The collation unit 1503 collates the collection result of the collection unit 1105 with the work process table DB 1501 in the same time zone. Specifically, for example, collating unit 1503 collates the remaining attribute information with each other by designating key attribute information in the collection result and work process schedule information 1600. As an example, assume that the attribute information serving as a key is an operator number, and the remaining attribute information is an operation number and a production number.

  The collation unit 1503 finds a record in which the worker numbers 1601 and 1701 match and the start time 1604 and the end time 1605 of the work schedule information 1600 include the start time 1704 and the end time 1705 of the collection result 1700. , From the collected result 1700 and the work schedule information 1600. Then, the collating unit 1503 compares the operation numbers 1602 and 1702 and the production numbers 1603 and 1703 of both the identified records, and when they do not match, collects the operation number 1602 and the production number 1603 of the operation process schedule information 1600 and the collection result 1700. To the record. After that, the output unit 1104 stores the latest collection result 1700 in the collection result DB 1502. Thereby, it is possible to confirm whether or not the work has been performed according to the work process schedule information 1600.

  FIG. 17 is an explanatory diagram showing an example of the storage contents of the collection result stored in the collection result DB 1502. The collection result 1700 is a table of an operator number 1701, an operation number 1702, a production number 1703, a start time 1704, an end time 1705, an operation process list operation number 1706, and an operation process list production number 1707. Information. The worker number 1701 is identification information for uniquely identifying the worker. The work number 1702 is identification information for uniquely specifying a work. The production number 1703 is identification information for uniquely specifying a product. The start time 1704 is a time at which the work specified by the record is started. The end time 1705 is a time at which the work specified by the record ends.

  The work process table work number 1706 is the work number 1602 of the work process table information 1600. The work process table manufacturing number 1707 is the manufacture number 1603 of the work process table information 1600. In the collected result, a record in which the work schedule work number 1706 and the work schedule serial number 1707 are not stored is a record in which the collection result 1700 matches the work schedule information 1600 in the matching unit 1503. On the other hand, in the collection result 1700, the record in which the work process table work number 1706 and the work process table manufacturing number 1707 are stored is compared in the collation unit 1503 with the work result 1602 by comparing the collected result 1700 with the work process table information 1600. , 1702 and serial numbers 1603, 1703 do not match.

  FIG. 18 is an explanatory diagram of an example of an output screen of a collection result according to the second embodiment. The difference from FIG. 14 is that the operation number of the operation schedule and the serial number of the operation schedule are displayed in correspondence with FIG.

  FIG. 19 is a flowchart illustrating an example of a collation processing procedure performed by the collation unit 1503. The management apparatus 101 specifies attribute information (eg, worker number) that is the same key as the key specified by the collection unit 1105 (step S1901). Next, the management apparatus 101 determines whether there is an unselected collection section (step S1902). When there is an unselected collection section (step S1902: Yes), the management apparatus 101 selects an unselected collection section (step S1903). The management apparatus 101 extracts records including the key and within the selected collection section from the work process chart information 1600 and the collection result (step S1904).

  The management apparatus 101 determines whether the work numbers 1602, 1702 and the serial numbers 1603, 1703 of both the extracted records match (step S1905). If they match (step S1905: YES), the management apparatus 101 stores an extraction record from the collection result 1700 in the collection result DB 1502 (step S1906). Then, control goes to a step S1902. On the other hand, if they do not match (step S1905: No), the management apparatus 101 stores in the collection result DB 1502 the extracted record from the collected result and the work number 1702 and serial number 1703 of the extracted record from the work schedule information 1600. It is stored (step S1907). Then, control goes to a step S1902.

  In step S1902, when there is no unselected collection section (step S1902: No), the management apparatus 101 ends the matching processing. Accordingly, the administrator can confirm whether or not the work has been performed according to the work process chart information 1600.
