In addition, the work time varies greatly depending on inefficient work performed by the worker. Note that the inefficient work is, for example, work for an operator to obtain tools and materials necessary for production because they are not prepared in the workplace.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a work time analysis support system 100 according to an embodiment of the present invention.
As shown in FIG. 1, the work time analysis support system 100 includes a work time analysis support device 10, an RFID (Radio Frequency IDentification) reader 20, a plurality of IC (Integrated Circuit) tags 30, a physical condition measuring device 40, Is provided. Although FIG. 1 shows the communication network 50 and the external server 60, the work time analysis support system 100 will be described as not including these configurations. In the present embodiment, “work” means “part of work of producing a product from raw materials using a mold”.

  As shown in FIG. 1, a work time analysis support apparatus 10 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a hard disk 14, and a USB (Universal Serial). (Bus) interface 15, keyboard 16, monitor 17, and NIC (Network Interface Card) 18. Each component provided in the work time analysis support apparatus 10 is connected via a bus. The work time analysis support apparatus 10 can be configured by a personal computer, for example.

  The CPU 11 controls the operation of the entire work time analysis support apparatus 10 according to a program stored in the hard disk 14. The CPU 11 is connected to each component via a bus, and exchanges control signals and data.

  The ROM 12 stores an IPL (Initial Program Loader) that is executed immediately after the power is turned on. After the IPL is executed, the CPU 11 reads the program stored in the hard disk 14 into the RAM 13 and executes it.

  The RAM 13 temporarily stores data and programs. The RAM 13 temporarily stores a program read from the hard disk 14, data necessary for work time presentation processing, and the like.

  The hard disk 14 stores a program executed by the CPU 11. The hard disk 14 stores information necessary for the work time presentation process. Here, the information stored in the hard disk 14 will be described in detail with reference to FIG.

  As shown in FIG. 2, the hard disk 14 includes ideal trajectory information 141, detected trajectory information 142, a physical condition table 143, an experience year table 144, a weather table 145, a lightness table 146, a concentration table 147, and a physical condition. Information 153, experience years information 154, weather information 155, lightness information 156, and density information 157 are stored.

  The ideal trajectory information 141 includes a trajectory (hereinafter referred to as an “ideal trajectory”) of an ideal position (hereinafter referred to as an “ideal trajectory position”) through which the worker passes during work in the work place, and the ideal trajectory by the worker. This is information representing an ideal time for passing through each ideal passing position on the locus (hereinafter referred to as "ideal passing time"). For example, the ideal trajectory information 141 is expressed by a plurality of records including a set of an ideal passage position and an ideal passage time. Note that the ideal passing position is expressed using, for example, an X coordinate and a Y coordinate. The ideal passage time is expressed by, for example, hour, minute, second.

  The detected trajectory information 142 includes a trajectory (hereinafter referred to as “detected trajectory”) of a position (hereinafter referred to as “detected trajectory”) at which it is detected that an operator has passed during work in the workplace, and This is information indicating the time at which it was detected that each position on the locus was detected (hereinafter referred to as “detection time”). The detection trajectory information 142 is expressed by a plurality of records configured from a set of a detection position and a detection time, for example. The detection position is expressed using, for example, an X coordinate and a Y coordinate. The detection time is expressed by, for example, hour, minute, second.

  The physical condition table 143 is a table representing the relationship between the physical condition of the worker and the work speed of the worker. The physical condition is represented by, for example, a physical condition coefficient determined based on blood pressure, body temperature, heart rate, and the like. In the present embodiment, the physical condition coefficient is assumed to be smaller as the physical condition becomes worse, with 100% being the best physical condition. The work speed is represented by a work speed coefficient. In the present embodiment, the work speed coefficient is 100% when the work speed is the fastest, and becomes smaller as the work speed becomes slower. FIG. 3A shows an example of the physical condition table 143. FIG. 3A shows an example in which the physical condition coefficient matches the work speed coefficient, that is, an example in which the work speed coefficient decreases as the physical condition coefficient decreases. The physical condition table 143 is set in this way because it is common that the work speed of the worker is slower as the physical condition of the worker is worse.

  The experience years table 144 is a table representing the relationship between the years of experience of the work of the worker and the work speed of the worker. The number of years of experience is represented by a numerical value representing the number of years of experience, for example. FIG. 3B shows an example of the experience year table 144. FIG. 3B shows an example in which the work speed coefficient is smaller as the years of experience are shorter. The experience years table 144 is set in this way because it is common that the work speed of the worker becomes slower as the experience year of the worker is shorter.

  The weather table 145 is a table representing the relationship between the weather during work and the work speed of the worker. The weather is represented by, for example, a character string representing the weather. FIG. 4A shows an example of the weather table 145. FIG. 4A shows an example in which the work speed coefficient is small when the weather is bad (for example, rain, lightning, or snow). The reason why the weather table 145 is set in this way is that when the weather is bad, the work speed of the worker is generally slow. For example, when it is raining, the floor slips, which may limit the moving speed. In addition, during lightning, the sound may not be heard well, which may slow down the work. In addition, when it is snowing, it can be slow and work can be slow due to cold hands.

  The brightness table 146 is a table representing the relationship between the brightness of the workplace and the work speed of the worker. The brightness is represented by a numerical value representing an illuminance level, for example. FIG. 4B shows an example of the brightness table 146. FIG. 4B shows an example in which the work speed coefficient decreases as the illuminance level decreases. The lightness table 146 is set in this way because it is common that the work speed of the worker becomes slower as the illuminance level of the workplace is lowered. For example, when the work to be performed by the worker is a work for incorporating parts of precision equipment, the work efficiency may be lowered if the brightness of the work place becomes dark.

  The concentration table 147 is a table representing the relationship between the concentration of impurities contained in the raw material used for production and the work speed of the worker. The concentration of the impurity is represented by a numerical value representing the amount of suspended particulate matter contained in the raw material, for example. FIG. 4C shows an example of the density table 147. FIG. 4C shows an example in which the work speed coefficient decreases as the amount of suspended particulate matter increases. The reason why the concentration table 147 is set in this manner is that the work speed of the worker is generally reduced as the amount of suspended particulate matter contained in the raw material increases.

  The physical condition information 153 is information representing the physical condition of the worker. The physical condition of the worker is represented by, for example, a physical condition coefficient determined by the physical condition measuring device 40 and determined based on the blood pressure, body temperature, heart rate, and the like of the worker. The physical condition coefficient is determined to be 100% when the blood pressure, the body temperature, and the heart rate of the worker are within these normal ranges, and is set to a smaller value as the worker moves out of the normal range.

  The years of experience information 154 is information representing the years of experience of the work of the worker. The years of experience are represented by numerical values, for example.

  The weather information 155 is information representing the weather during work. The weather at the time of work is represented by a character string representing the weather such as sunny, cloudy, rainy, thunder, or snow.

  The brightness information 156 is information representing the brightness of the workplace. The brightness of the workplace is represented by a numerical value representing the illuminance level, for example.

  The concentration information 157 is information representing the concentration of impurities contained in the raw material used for production. The concentration of the impurity is represented by a numerical value representing the amount of suspended particulate matter contained in the raw material, for example.

On the other hand, the detection locus information 142 is supplied from the RFID reader 20 to the hard disk 14 in the detection locus acquisition process described later. The physical condition information 153 is supplied from the physical condition measuring device 40 to the hard disk 14.

  The USB interface 15 receives the detection trajectory information 142 from the RFID reader 20 and the physical condition information 153 from the physical condition measuring device 40 under the control of the CPU 11. Note that the work time analysis support device 10 may include a flexible disk drive instead of the USB interface 15, or may include a flexible disk drive in addition to the USB interface 15. In this case, the CPU 11 stores the detected locus information 142 or the physical condition information 153 stored in the flexible disk inserted in the flexible disk drive in the hard disk 14.

  The keyboard 16 receives various operation inputs from the user. The work time analysis support device 10 may include a mouse instead of the keyboard 16 or may include a mouse in addition to the keyboard 16.

  The NIC 18 transmits and receives various types of information to and from the external server 60 via the communication network 50 under the control of the CPU 11.

The RFID reader 20 is a device that can read a tag ID stored in the IC tag 30 and is a device that is carried by an operator. The RFID reader 20 can be incorporated into, for example, an operator's shoes.
As shown in FIG. 5, the RFID reader 20 includes a timer unit 21, a tag reading unit 22, a tag position storage unit 23, a detection position calculation unit 24, a detection locus storage unit 25, and a detection locus output unit 26. .

  The timer unit 21 outputs the current time. The timer unit 21 is configured by, for example, an RTC (Real Time Clock).

  The tag reading unit 22 reads the tag ID from the communicable IC tag 30 using radio waves or the like every time the current time supplied from the time measuring unit 21 reaches a predetermined detection time. The detection time can be, for example, a time that arrives every 10 seconds. In addition, the communicable IC tag 30 is, for example, an IC tag 30 that is within a predetermined distance from the RFID reader 20 among the plurality of IC tags 30 arranged in the workplace. The tag reading unit 22 includes, for example, a radio wave transmission / reception IC, a CPU, a ROM, and a RAM.

  The tag position storage unit 23 sets the tag ID of the IC tag 30 and the position where the IC tag 30 is disposed (hereinafter referred to as “tag position”) for all the IC tags 30 disposed in the work place. Store in association with each other. The tag position is represented by, for example, an X-axis coordinate parallel to the floor surface of the work place and a Y-axis coordinate parallel to the floor surface and orthogonal to the X axis. The tag position storage unit 23 is configured by, for example, a flash memory.

  Based on the tag ID read by the tag reading unit 22 and the tag position stored in the tag position storage unit 23, the detection position calculation unit 24 obtains the position of the worker in the workplace. For example, when there is one tag ID read by the tag reading unit 22, the tag position associated with the tag ID and stored in the tag position storage unit 23 is set as the detection position. On the other hand, when a plurality of tag IDs are read, for example, the center of gravity of the tag position stored in association with each tag ID is set as the detection position. The detection position calculation unit 24 includes, for example, a CPU, a ROM, and a RAM.

  The detection locus storage unit 25 stores the supplied detection position and the detection time supplied by the timer unit 21 in association with each other when the detection position is supplied by the detection position calculation unit 24. The information stored in the detection locus storage unit 25 is the detection locus information 142 described above. The detection locus storage unit 25 is configured by, for example, a flash memory.

  The detection trajectory output unit 26 reads the detection trajectory information 142 stored in the detection trajectory storage unit 25 and supplies it to the work time analysis support apparatus 10. The detection locus output unit 26 is configured by, for example, a USB interface.

  The IC tag 30 is an IC that stores a unique tag ID. In the present embodiment, a plurality of IC tags 30 are arranged in a matrix under the floor of the work place.

  The physical condition measuring device 40 measures the physical condition of the worker. Specifically, the physical condition measuring device 40 measures, for example, a worker's blood pressure, body temperature, and heart rate. Here, the physical condition measuring instrument 40 supplies physical condition information 153 representing the measurement result to the working time analysis support apparatus 10. In this embodiment, the physical condition information 153 is represented by a physical condition coefficient determined based on the measured blood pressure, body temperature, heart rate, and the like of the worker. The physical condition coefficient is set to a higher value as the physical condition of the worker is better.

  The communication network 50 is a network such as the Internet or a LAN (Local Area Network). The communication network 50 connects the work time analysis support apparatus 10 and the external server 60 and relays various information transmitted and received between the work time analysis support apparatus 10 and the external server 60.

  The external server 60 provides various information to the work time analysis support apparatus 10 via the communication network 50. For example, the external server 60 stores the ideal trajectory information 141, the physical condition table 143, the experience year table 144, the weather table 145, the lightness table 146, the concentration table 147, the experience year information 154, the weather information 155, the lightness information 156, and the concentration information 157. This is provided to the work time analysis support apparatus 10. Various types of information provided from the external server 60 are stored in the hard disk 14 as appropriate.

Next, basic functions of the work time analysis support system 100 will be described with reference to FIG.
As shown in FIG. 6, the work time analysis support system 100 functionally includes an ideal trajectory reception unit 101, a detection trajectory reception unit 102, a work time calculation unit 103, and a work time presentation unit 104. Is done.

  The ideal trajectory receiving unit 101 receives ideal trajectory information 141. The ideal locus receiving unit 101 is configured by, for example, the NIC 18.

  The detection locus receiving unit 102 receives the detection locus information 142. The detection locus receiving unit 102 is configured by, for example, the USB interface 15.

  Based on the ideal trajectory information 141 received by the ideal trajectory accepting unit 101 and the detected trajectory information 142 accepted by the detection trajectory accepting unit 102, the work time calculating unit 103 calculates the net amount required by the operator for the work. Calculate work time. The work time calculation unit 103 includes, for example, a CPU 11, a ROM 12, and a RAM 13.

  The work time calculation unit 103 includes a start / end position specifying unit 1031, a time difference calculation unit 1032, a dead time calculation unit 1033, and a work time correction unit 1034.

  The start / end position specifying unit 1031 is based on the ideal trajectory information 141, the position where the worker should start work (hereinafter referred to as “start position”), and the position where the worker should end work (hereinafter referred to as “end position”). ”). For example, the ideal passing position associated with the earliest time among the ideal passing times represented by the ideal trajectory information 141 is specified as the start position. Further, the ideal passing position associated with the latest time among the ideal passing times represented by the ideal trajectory information 141 is specified as the end position.

  The time difference calculation unit 1032 is based on the detection trajectory information 142, the time when the worker passes the start position specified by the start / end position specification unit 1031 (hereinafter referred to as “start time”), and the start / end position specification unit. A time difference from the time when the worker passes the end position specified by 1031 (hereinafter referred to as “end time”) is obtained. For example, the detection time associated with the detection position that matches the start position among the detection positions represented by the detection trajectory information 142 is specified as the start time. In addition, the detection time associated with the detection position that matches the end position among the detection positions represented by the detection trajectory information 142 is specified as the end time. Then, a time difference between the specified start time and the specified end time is obtained.

  The dead time calculation unit 1033 is consumed for work that is not directly related to work to be performed by the worker (hereinafter referred to as “unrelated work”) based on the ideal trajectory information 141 and the detected trajectory information 142. The total time (hereinafter referred to as “dead time”) is calculated. For example, when a detection position whose distance from the ideal trajectory is equal to or greater than a predetermined threshold is included in the detection trajectory, it can be considered that the worker has moved for an unrelated work. For this reason, the time spent for the movement is a dead time. For example, when the worker goes to the toilet, the time consumed to go to the toilet is a dead time. Further, for example, when the ideal trajectory and the detection trajectory coincide with each other in a predetermined section, the time difference between the ideal time required to pass through the section and the actual time required to pass through the section However, if it is equal to or greater than the predetermined threshold value, the worker can be considered to have stayed in the same place for a long time because of work not directly related to work to be performed. For this reason, the time difference is a dead time.

  The work time correction unit 1034 subtracts the dead time obtained by the dead time calculation unit 1033 from the time difference obtained by the time difference calculation unit 1032 to obtain a work directly related to the work to be performed by the worker. Therefore, the work time spent for the purpose (hereinafter referred to as “net work time” as appropriate) is obtained.

  Note that the work time calculation unit 103 uses the net work time obtained by the work time correction unit 1034 as the ideal trajectory information 141 received by the ideal trajectory reception unit 101 and the detected trajectory information received by the detection trajectory reception unit 102. 142 and various information are corrected as appropriate.

  The work time presentation unit 104 presents the net work time obtained by the work time correction unit 1034. The work time presentation unit 104 is configured by, for example, the monitor 17.

  FIG. 6 shows an example in which the ideal trajectory information 141 and various types of information are supplied from the outside to the work time analysis support system 100, but the work time analysis support system 100 stores these information in advance. Also good. Further, the detection trajectory information 142 may not be information supplied to the work time analysis support system 100 from the outside, but may be information that the work time analysis support system 100 calculates by itself.

  Next, the operation of the work time analysis support system 100 according to the present embodiment will be described. First, with reference to FIG. 7, the detection locus acquisition process executed by the RFID reader 20 included in the work time analysis support system 100 will be described.

  First, the RFID reader 20 determines whether or not the current time is the detection start time (step S101). Specifically, the tag reading unit 22 determines whether or not the current time supplied from the time measuring unit 21 matches the detection start time stored in advance in the ROM. If the RFID reader 20 determines that it is not the detection start time (step S101: NO), it executes the process of step S101 again.

  On the other hand, when the RFID reader 20 determines that the current time is the detection start time (step S101: YES), the RFID reader 20 determines whether the current time is the detection time (step S102). Specifically, the tag reading unit 22 determines whether or not the current time supplied from the time measuring unit 21 matches the detection time stored in advance in the ROM. If the RFID reader 20 determines that the current time is not the detection time (step S102: NO), it executes the process of step S102 again.

  When it is determined that the current time is the detection time (step S102: YES), the RFID reader 20 reads the tag ID (step S103). Specifically, the tag reading unit 22 reads the tag ID stored in the IC tag 30 using radio waves or the like.

  When the processing of step S103 is completed, the RFID reader 20 calculates a detection position where it is estimated that there is an operator (step S104). Specifically, the detection position calculation unit 24 obtains the center of gravity of the tag position stored in the tag position storage unit 23 in association with the tag ID read in step S103, and determines the obtained center of gravity of the operator. The detection position.

  When the processing of step S104 is completed, the RFID reader 20 stores the detection time and the detection position in association with each other (step S105). Specifically, the detection locus storage unit 25 stores the current time determined as the detection time in step S102 and the detection position calculated in step S104 in association with each other.

  When the RFID reader 20 finishes the process of step S105, the RFID reader 20 determines whether or not the current time is the detection end time (step S106). Specifically, the tag reading unit 22 determines whether or not the current time supplied from the time measuring unit 21 matches the detection end time stored in advance in the ROM.

  If the RFID reader 20 determines that the current time is not the detection end time (step S106: NO), the process returns to step S102. On the other hand, when the RFID reader 20 determines that the current time is the detection end time (step S106: YES), the detection trajectory acquisition process ends.

  The detection locus information 142 is stored in the detection locus storage unit 25 by the detection locus acquisition process.

  Here, the detection trajectory information 142 acquired in the detection trajectory acquisition process will be described with reference to FIGS.

  First, the ideal locus information 141 and the detected locus information 142 will be described with reference to FIG. FIG. 8 is a plan view showing the state of the work place. As shown in FIG. 8, the work place 200 includes a first equipment 201, a second equipment 202, a material storage place 203, a mold storage place 204, an examination room 205, a break room 206, and a toilet 207. Has been placed.

  In the present embodiment, the worker starts work in the first facility 201, moves to the mold place 204, holds the mold, moves to the inspection room 205, inspects the mold, and then performs the second facility 202. It will be assumed that the operation is finished after moving to. When the worker performs such work, an ideal route that the worker should take during the work is an ideal locus 210 indicated by a broken line in FIG. Accordingly, the ideal trajectory information 141 is information representing the position on the ideal trajectory 210 indicated by the broken line and the time at which the operator should pass through the position.

  On the other hand, the worker actually starts work in the first facility 201, goes to the material storage 203 to pick up the material, returns to the first facility 201 again, moves to the mold storage 204 and holds the mold. Suppose that it moves to the inspection room 205, inspects the mold, moves to the toilet 207, moves to the second facility 202, and finishes the work. In this case, the actual route that the worker has taken during the work is a detection locus 211 indicated by a solid line in FIG. Accordingly, the detection trajectory information 142 is information representing the position on the detection trajectory 211 indicated by the solid line and the time when the worker has passed the position.

  Next, a method for calculating the detection position will be described with reference to FIG. Note that the actual route that the operator has taken during the work is assumed to be the detection locus 211 indicated by the solid line in FIG. In FIG. 9, the axis extending in the left-right direction is defined as the X axis, and the axis extending in the vertical direction is defined as the Y axis.

  For example, it is assumed that the worker is at the position P0 at a certain detection time t0. At this time, among the plurality of IC tags 30 arranged in a matrix in the workplace, the IC tag 30 whose tag ID is read by the RFID reader 20 is displayed in vertical stripes in FIG. 9 and is arranged in the vicinity of the position P0. The IC tag 31 and the IC tag 32 are provided. In this case, the coordinates of the IC tag 31 represented by the tag position stored in the tag position storage unit 23 in association with the tag ID read from the IC tag 31, and the tag read from the IC tag 32 The position represented by the center of gravity of the two coordinates of the coordinates of the IC tag 32 represented by the tag position stored in the tag position storage unit 23 in association with the ID is set as the detection position.

  Further, it is assumed that the worker is at the position P1 at another detection time t1. At this time, the IC tag 30 whose tag ID is read by the RFID reader 20 is one of the IC tags 33 that are displayed in a solid color in FIG. 9 and arranged near the position P1. In this case, the position represented by the coordinates of the IC tag 33 represented by the tag position stored in the tag position storage unit 23 in association with the tag ID read from the IC tag 33 is set as the detection position. .

  Furthermore, it is assumed that the worker is at the position P2 at another detection time t2. At this time, the IC tags 30 whose tag IDs are read by the RFID reader 20 are displayed as horizontal stripes in FIG. 9 and are four IC tags 34 to 37 arranged in the vicinity of the position P2. In this case, the position represented by the center of gravity of the four coordinates of the IC tags 34 to 37 acquired from the tag position storage unit 23 is set as the detection position. The detection trajectory information 142 is represented by a plurality of sets of detection positions and detection times obtained in this way.

  Next, a work time presentation process executed by the work time analysis support apparatus 10 included in the work time analysis support system 100 will be described with reference to FIG. The work time presentation process is a process for obtaining a net work time and a work time obtained by correcting the net work time based on the detection trajectory information 142 acquired by the detection trajectory acquisition process. Here, the various information shown in FIG. 2 will be described as being stored in the hard disk 14 prior to the work time presentation process. Further, for example, when the work time analysis support device 10 receives an instruction input to start the work time presentation process from the user, the work time analysis support apparatus 10 starts the work time presentation process.

  First, the CPU 11 specifies a start position and an end position based on the ideal locus information 141 stored in the hard disk 14 (step S201). For example, the CPU 11 sets the ideal passing position with the earliest ideal passing time among the plurality of ideal passing positions represented by the ideal trajectory information 141 as the start position, and the corresponding ideal passing time is the most. The slow ideal passing position is the end position.

  When the CPU 11 finishes the process of step S201, the CPU 11 specifies a start time and an end time based on the detected locus information 142 stored in the hard disk 14 (step S202). For example, the CPU 11 uses the detection time associated with the detection position that matches the start position among the plurality of detection positions represented by the detection locus information 142 as the start time, and associates it with the detection position that matches the end position. The detected time is the end time.

  When the CPU 11 finishes the process of step S202, it calculates the time difference between the start time and the end time specified in step S202 (step S203). Note that the calculated time difference is the time from the start to the end of the work to be performed by the worker, but this time includes the wasted time spent for irrelevant work. there is a possibility.

  When the CPU 11 finishes the process of step S203, the CPU 11 calculates a dead time required for the irrelevant work based on the ideal locus information 141 and the detected locus information 142 (step S204). For example, in the example illustrated in FIG. 8, the irrelevant work is a work in which the worker moves from the first equipment 201 to the material storage 203 and returns to the first equipment 201 again, or a work in which the worker stops at the toilet 207. A method for determining whether or not an irrelevant work has occurred during the work is arbitrary.

  For example, it is determined that an irrelevant work has occurred when there is a detection position that is more than a predetermined distance from the ideal trajectory represented by the ideal trajectory information 141 among the detection positions represented by the detection trajectory information 142. Can do. In addition, when a detection position where it is determined that the worker stays for a long time based on the detection locus information 142 exists in the detection locus, the ideal locus information 141 determines that the worker does not stay for a long time. If it is, it can be determined that unrelated work has occurred. In other words, even if the ideal trajectory and the detection trajectory match, if the worker stays at a certain detection position on the detection trajectory for a longer time than the ideal staying time, It can be determined that the person is performing unrelated work.

  As described above, when it is determined that an irrelevant work has occurred, the dead time spent for performing the irrelevant work is subtracted from the time difference calculated in step S203, thereby spending the work to be performed by the worker. Net working time can be calculated. The dead time can be estimated based on the ideal trajectory information 141 and the detected trajectory information 142. For example, among the detection positions on the detection trajectory, the detection time associated with the detection position considered to start moving away from the ideal trajectory, and the detection position considered to have returned to the ideal trajectory among the detection positions on the detection trajectory The time difference from the detection time associated with is defined as a dead time.

  When the CPU 11 finishes the process of step S204, the CPU 11 calculates the net work time by subtracting the dead time determined in step S204 from the time difference determined in step S203 (step S205).

  CPU11 correct | amends the working time calculated | required by step S205 based on the physical condition table 143 and the physical condition information 153 which are memorize | stored in the hard disk 14, if the process of step S205 is complete | finished (step S206). Specifically, the CPU 11 reads the work speed coefficient associated with the physical condition coefficient represented by the physical condition information 153 from the physical condition table 143, and multiplies the read work speed coefficient by the work time obtained in step S205. . Thereby, the work time calculated | required by step S205 is correct | amended based on a worker's physical condition. For example, when the worker's physical condition is good, the work time is not corrected, but when the worker's physical condition is bad, the work time is corrected so as to be shortened.

  CPU11 correct | amends the working time calculated | required by step S206 based on the experience years table 144 and the experience years information 154 which are memorize | stored in the hard disk 14, if the process of step S206 is complete | finished (step S207). Specifically, the CPU 11 reads out the work speed coefficient associated with the years of experience represented by the years of experience information 154 from the years of experience table 144, and reads the work speed coefficients that have been read out in the work time obtained in step S206. Multiply Thereby, the work time calculated | required by step S206 is correct | amended based on an operator's experience years. For example, when the worker's experience years are long, the work time is not corrected, but when the worker's experience years are short, the work time is corrected so as to be shortened.

  CPU11 correct | amends the working time calculated | required by step S207 based on the weather table 145 and the weather information 155 which are memorize | stored in the hard disk 14, if the process of step S207 is complete | finished (step S208). Specifically, the CPU 11 reads the work speed coefficient associated with the weather represented by the weather information 155 from the weather table 145, and multiplies the read work speed coefficient by the work time obtained in step S207. Thereby, the work time calculated | required by step S207 is correct | amended based on the weather at the time of work. For example, when the working weather is good, the working time is not corrected, but when the working weather is bad, the working time is corrected to be shortened.

  CPU11 correct | amends the working time calculated | required by step S208 based on the brightness table 146 and the brightness information 156 which are memorize | stored in the hard disk 14, if the process of step S208 is complete | finished (step S209). Specifically, the CPU 11 reads a work speed coefficient associated with the illuminance level represented by the lightness information 156 from the lightness table 146, and multiplies the read work speed coefficient by the work time obtained in step S208. . Thereby, the work time calculated | required by step S208 is correct | amended based on the brightness of a workplace. For example, when the lightness of the work place is high (bright), the work time is not corrected, but when the lightness of the work place is low (dark), the work time is corrected to be short.

  When the CPU 11 finishes the process of step S209, the CPU 11 corrects the work time obtained in step S209 based on the density table 147 and density information 157 stored in the hard disk 14 (step S210). Specifically, the CPU 11 reads the work speed coefficient associated with the suspended particulate matter amount represented by the concentration information 157 from the concentration table 147, and reads the read work speed coefficient at the work time obtained in step S209. Multiply Thereby, the work time calculated | required by step S208 is correct | amended based on the amount of suspended particulate substances contained in the raw material used for production. For example, when the amount of suspended particulate matter is small, the working time is not corrected, but when the amount of suspended particulate matter is large, the working time is corrected so as to be shortened.

  CPU11 will show the working time calculated | required by step S210 to a user, after complete | finishing the process of step S210 (step S211).

  CPU11 complete | finishes a work time presentation process, after complete | finishing the process of step S211.

  According to the work time analysis support system 100 according to the present embodiment, the net work time required for the work to be performed by the worker can be presented to the user. Here, the net work time is a time in which time spent for work not related to work to be performed by the worker is excluded. For this reason, the user can know only the net work time spent on work to be performed by the worker. In addition, the net work time is corrected in consideration of the physical condition of the worker, the years of experience of the worker, the weather during the work, the brightness of the workplace, and the amount of suspended particulate matter contained in the raw materials used in production. . For this reason, the work time to be presented is one in which the influence of the condition when the worker works is reduced.

  As mentioned above, although embodiment of this invention was described, in implementing this invention, the deformation | transformation and application by a various form are possible, and it is not restricted to the said embodiment.

  In the above embodiment, when the actual time required to execute a certain work (the time difference obtained in step S203) is longer than the time predicted to be required to execute the work, it is useless. Considering that there is time spent for work (dead time), an example is shown in which the time obtained by subtracting the dead time from the measured actual time is obtained as the net working time (steps S203 to S205). . However, in the present invention, when the actual time required to execute a certain work is shorter than the predicted time required to execute the work, an appropriate net is appropriately selected according to the cause. It is also possible to determine the working time.

  For example, when the cause is that the worker has forgotten the work to be performed, it is necessary to correct the measured actual time by the time required to execute the forgotten work. Therefore, the net work time is defined as a time obtained by adding the time estimated to be required to perform the forgotten work to the measured actual time. It should be noted that if the position close to the predetermined position on the ideal trajectory is not on the detection trajectory, and / or if the time difference between the measured actual time and the predicted time is greater than a predetermined threshold, the operation is performed. It can be considered that forgetting is the cause.

  On the other hand, if the cause is an improvement in work efficiency (for example, material improvement, work procedure improvement, operator familiarity, or fine-tuning of the workplace layout), the measured real time is It can be considered working time. Accordingly, the measured actual time itself is set as the net work time. It should be noted that when the positions close to all the positions on the ideal trajectory are on the detection trajectory and / or when the time difference between the measured actual time and the predicted time is smaller than a predetermined threshold, the work efficiency The improvement can be considered as the cause.

  Further, when the improvement in work efficiency is considered to be the cause, the work time analysis support system so as to correct the ideal trajectory information 141 based on the detection trajectory information 142 acquired by the detection trajectory acquisition process shown in FIG. 100 may be configured. For example, the acquired detected trajectory information 142 itself can be adopted as the ideal trajectory information 141, or a part of the ideal trajectory information 141 (the time required in reality can be predicted using the acquired detected trajectory information 142. It is also possible to rewrite a portion representing a trajectory that the worker has passed when performing work shorter than the predetermined time.

  Here, with reference to FIG. 11, the work time presentation process which the work time analysis system which concerns on a modification performs is demonstrated.

  First, the CPU 11 specifies a start position and an end position based on the ideal locus information 141 stored in the hard disk 14 (step S301).

  When the CPU 11 finishes the process of step S301, the CPU 11 specifies a start time and an end time based on the detected locus information 142 stored in the hard disk 14 (step S302).

  When the CPU 11 finishes the process of step S302, it calculates the time difference between the start time and the end time specified in step S302 (step S303).

  When completing the process of step S303, the CPU 11 calculates an ideal time difference based on the ideal trajectory information 141 stored in the hard disk 14 (step S304). Specifically, the CPU 11 is the time between the earliest ideal passage time among the ideal passage times represented by the ideal locus information 141 and the latest ideal passage time among the ideal passage times represented by the ideal locus information 141. Find the difference and make it the ideal time difference.

  When completing the process in step S304, the CPU 11 determines whether or not the time difference obtained in step S303 is greater than or equal to the ideal time difference obtained in step S304 (step S305).

  When determining that the time difference obtained in step S303 is equal to or larger than the ideal time difference obtained in step S304 (step S305: YES), the CPU 11 calculates a dead time (step S306). When the CPU 11 completes the process of step S306, it calculates the net work time by subtracting the dead time determined in step S306 from the time difference determined in step S303 (step S307).

  On the other hand, if the CPU 11 determines that the time difference obtained in step S303 is not greater than or equal to the ideal time difference obtained in step S304 (step S305: NO), the CPU 11 obtains the time difference obtained in step S303 and the step S304. It is determined whether or not the time difference from the determined ideal time difference is equal to or greater than a predetermined threshold (step S309).

  If the CPU 11 determines that the time difference between the time difference obtained in step S303 and the ideal time difference obtained in step S304 is equal to or greater than a predetermined threshold (step S309: YES), the CPU 11 calculates a forgetting time (step S310). ). The forgotten time is a work to be performed by the worker, and is a time estimated to be required for the worker to perform the forgotten work. This forgetful time can be obtained from the ideal trajectory information 141 and the detected trajectory information 142, as in the dead time. When the CPU 11 finishes the process of step S309, the CPU 11 calculates the net work time by adding the forgetting time obtained in step S309 to the time difference obtained in step S303 (step S311).

  If the CPU 11 determines that the time difference between the time difference obtained in step S303 and the ideal time difference obtained in step S304 is not equal to or greater than a predetermined threshold (step S309: NO), the CPU 11 calculates a net work time ( Step S312). Here, the CPU 11 does not correct the time difference obtained in step S303, and uses the uncorrected time difference as the net work time. When the CPU 11 finishes the process of step S <b> 312, the CPU 11 updates the ideal trajectory information 141 stored in the hard disk 14 based on the detected trajectory information 142 stored in the hard disk 14. Typically, the ideal locus information 141 is overwritten with the detected locus information 142.

  When the CPU 11 completes the process of step S307, step S311, or step S313, the CPU 11 presents the net work time obtained in step S307, step S311 or step S312 to the user (step S308).

  CPU11 complete | finishes a working time presentation process, after complete | finishing the process of step S308. In step S309, in addition to (or instead of) whether or not the time difference between the time difference calculated in step S303 and the ideal time difference calculated in step S304 is equal to or greater than a threshold value, a predetermined value on the ideal locus is set. Whether or not a position close to the position is on the detection locus may be used as a determination criterion. As a result, the reason why the time difference calculated in step S303 is shorter than the ideal time difference calculated in step S304 is either because of forgotten work or because work efficiency has improved. It becomes possible to more accurately determine whether or not. In FIG. 11, the processing in steps S206 to S210 for correcting the net work time is omitted, but these corrections may be performed.

  In the above embodiment, all correction factors (dead time, worker's physical condition, worker's years of experience, working weather, workplace brightness, and amount of suspended particulate matter contained in raw materials used for production) An example in which the work time corrected in consideration is presented to the user is shown. However, the working time corrected in consideration of only a specific factor among all the correction factors may be presented to the user. Further, the uncorrected work time may be presented to the user.

  In the above embodiment, an example is shown in which an operator carries the RFID reader 20 and a plurality of IC tags 30 are arranged below the floor of the work place. However, an operator may carry the IC tag 30 (for example, embed the IC tag 30 in a shoe sole) and install a plurality of RFID readers 20 below the floor of the work place.

  In the above-described embodiment, an example is shown in which the RFID reader 20 and the IC tag 30 are used to obtain the locus of the position where the worker has passed and the passage time of the position on the locus. However, the method for obtaining the trajectory of the position where the worker has passed and the passage time of the position on the trajectory is arbitrary. For example, these may be obtained by a barcode reader and a barcode. Alternatively, these may be obtained by an imaging device and an image analysis device.

  In the above-described embodiment, the example in which the detection trajectory information 142 and the physical condition information 153 are stored in the hard disk 14 prior to the work time presentation process is shown. However, these pieces of information may be stored in the hard disk 14 during the execution of the work time presentation process. In this case, for example, the RFID reader 20, the physical condition measuring device 40, and the work time analysis support device 10 are provided with a wireless communication function.

  In the said embodiment, the example which the RFID reader | leader 20 calculates the position which the operator passed was shown. However, the work time analysis support apparatus 10 may calculate the position where the worker has passed. In this case, the work time analysis support apparatus 10 includes a tag position storage unit 23 and a detection position calculation unit 24, and the RFID reader 20 determines at least one read tag ID and a detection time at which the tag ID is read. The work time analysis support apparatus 10 is supplied.

  In the above embodiment, an example in which the tag ID of the IC tag 30 is stored in the IC tag 30 is shown. However, information indicating the installation position of the IC tag 30 may be stored in the IC tag 30. In this case, the step of obtaining the tag position from the tag ID is not necessary.

  In the embodiment described above, when a plurality of tag IDs are read, an example in which the center of gravity of the tag positions corresponding to the plurality of tag IDs is set as the detection position has been described. However, based on the strength of radio waves when the RFID reader 20 reads the tag ID from the IC tag 30, a more accurate position of the worker may be estimated and used as the detection position.

  In the said embodiment, the example which correct | amends working time based on the weather at the time of work was shown. However, the work time may be corrected based on the temperature of the work place.

  In the above-described embodiment, an example has been described in which the RFID reader 20 and the IC tag 30 are used to detect that the worker is at a specific position (for example, a work start position). However, it may be detected that the worker is at the specific position by detecting that the operator has pressed a button installed at the specific position. Moreover, it may be detected that the worker is in the specific position by detecting the worker by a human sensor installed at the specific position. In addition, using an imaging device installed at a specific position and an image recognition device capable of recognizing the worker captured in the image captured by the imaging device, the worker is placed at the specific position. May be detected.

  In the above embodiment, the working time of the dead time, the physical condition of the worker, the years of experience of the worker, the weather at the time of work, the brightness of the work place, and the amount of suspended particulate matter contained in the raw material used for production is affected. An example is given in which the working time is corrected on the assumption that each given factor is independent of the other factors. However, the working time may be corrected assuming that these factors depend on each other.

  For example, when an irrelevant work occurs when the worker is in good physical condition, correction according to the dead time is executed. On the other hand, if unrelated work occurs when the physical condition of the worker is poor, only correction according to the physical condition of the worker is performed, and correction according to the dead time is not performed, or according to the physical condition of the worker Correction is not executed, but only correction according to dead time is executed. Thereby, it can prevent correcting too much by correcting work time redundantly.

  For example, when the operator has a long working experience, the working time is not corrected according to the lightness of the workplace. Longer years of experience are effective when it is considered that work can proceed without depending on the brightness of the workplace.

  Further, the work time analysis support device 10 constituting the work time analysis support system 100 according to the above embodiment is not limited to dedicated hardware, and can be realized by a normal computer system.

  For example, in the above embodiment, the operation time analysis support apparatus 10 has been described assuming that the operation program is stored in advance in a memory or the like. However, a computer readable recording such as a flexible disk, CD-ROM (Compact Disk Read-Only Memory), DVD (Digital Versatile Disk), MO (Magneto-Optical Disk), etc. An apparatus that performs the above-described processing operation may be configured by storing and distributing the program in a medium and installing the program in a computer.

Further, the program may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example. Furthermore, the above-described processing can also be achieved by starting and executing a program while transferring it via a communication network.
Further, when the above functions are realized by sharing an OS (Operating System) or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. Alternatively, it may be downloaded to a computer.
