Further, in the distance estimation process, worker height information (Zu) may be used as shown in FIG. In this case, the distance R from the position of the worker to the position where the manufacturing apparatus 20 is installed is estimated according to equation (2) described later. In addition, in (2) Formula mentioned later, the height of the manufacturing apparatus 20 shall be 0 for convenience.

In the distance estimation process, when the worker height information (Zu) is taken into consideration as described above, the weight applied to the height may be made larger than the others as shown in the following equation (3). (That is, it may be multiplied by a weighting factor α (where α> 1)). This is because when a worker is working at a high position (place), the worker is estimated to have moved to the high position using a stepladder, ladder, etc., even if the distance is the same. Even so, it is estimated that it takes more time to move up and down a stepladder or ladder than to move on a plane (ground or floor).

  11 and 12, the outline of the distance estimation process has been described. Hereinafter, the details of the processing procedure of the work assignment process including the distance estimation process will be described with reference to the flowchart shown in FIG. In FIG. 13, in addition to the position information indicating the position of the worker and the position information indicating the position of each manufacturing apparatus 20, the height information indicating the position of the worker in the height direction and the manufacturing by each manufacturing apparatus 20. A case will be described in which work is assigned to a worker using the urgency level indicating how quickly the work needs to be performed before starting the process. The process shown in FIG. 13 is executed by the management server device 40.

  First, a plurality of worker terminals 10 worn by a plurality of workers who work in the work area 100, for example, continuously drive the indoor positioning sensor 14, the acceleration sensor 15, and the atmospheric pressure sensor 16, thereby Along with the ID, the position information, acceleration information and height information of the worker are periodically transmitted to the management server device 40, respectively.

  Accordingly, the communication processing unit 42 included in the management server device 40 receives the position information, acceleration information, and height information of the worker who performs work in the work area 100 from the worker terminal 10 (block B1).

  When the process of block B1 is executed, the control unit 41 extracts process information indicating that the degree of urgency is high among the plurality of process information stored in the process information storage unit 46 (block B2). Specifically, process information including the urgency “1” is extracted from the process information storage unit 46. If process information including the urgency “1” is not stored in the process information storage 46, process information including the urgency “2” is extracted from the process information storage 46. When a plurality of pieces of process information including the degree of urgency “1” are stored in the process information storage unit 46, the plurality of pieces of process information are all extracted from the process information storage unit 46. In the following, for the sake of simplicity of explanation, it is assumed that one piece of process information including the urgency “1” is extracted from the process information storage unit 46.

  Next, the control unit 41 acquires, from the manufacturing apparatus information storage unit 45, manufacturing apparatus information including a manufacturing apparatus ID having the same value as the value of the manufacturing apparatus ID included in the extracted process information (block B3). When a plurality of process information is extracted in the process of block B2, the control unit 41 executes the process of block B3 for each of the plurality of process information.

  Subsequently, the control unit 41 is extracted by executing the process of the block B2 while the status indicates “standby” among the plurality of worker information received by executing the process of the block B1. One or more pieces of worker information including work availability information indicating that the work indicated by the work name (work information) included in the process information can be performed is extracted (block B4). When a plurality of process information is extracted in the process of block B2, the control unit 41 sequentially extracts one or more worker information while referring to each of the plurality of process information. For example, a predetermined worker is on standby and can perform one operation indicated by the extracted one process information, and further performs another operation indicated by the extracted other process information. When it is possible, the worker information indicating the predetermined worker is extracted as one of one or more pieces of worker information by the control unit 41 when any of these two pieces of process information is referred to.

  When the process of block B4 is executed, the control unit 41 executes the process of block B3 with each of the position information (second position information) and the height information included in the extracted one or more pieces of worker information. From each worker identified by the worker ID included in the one or more worker information based on the position information (first position information) included in the manufacturing apparatus information acquired by Each distance R to the manufacturing apparatus 20 identified by the manufacturing apparatus ID included in the manufacturing apparatus information is estimated (block B5). Specifically, the control unit 41 estimates the distance R from each worker to the manufacturing apparatus 20 using either the above-described formula (2) or formula (3). When not using the worker height information, the control unit 41 estimates the distance R from each worker to the manufacturing apparatus 20 by using the above-described equation (1).

  Thereafter, the control unit 41 uses the worker used to estimate the minimum distance minR among the distances R from the worker to the manufacturing apparatus 20 estimated by executing the process of block B5. The worker identified by the worker ID included in the information is selected as the worker who performs the work indicated by the work name included in the process information extracted by the execution of the process of block B2. The administrator terminal 30 is notified via the communication processing unit 42 (block B6), and the process here is terminated.

  When a plurality of pieces of process information are extracted in the process of block B2, the control unit 41 is identified by the manufacturing apparatus ID included in the one manufacturing apparatus information acquired by executing the process of block B3. The sum of the distance R1 from one manufacturing apparatus 20 to each worker and the distance R2 from another manufacturing apparatus 20 to each worker identified by the manufacturing apparatus ID included in the other manufacturing apparatus information is minimum. Select workers (assign work) so that Alternatively, when a plurality of process information is extracted, the control unit 41 includes the extracted process information in the process information at the time when the preparation start time (or manufacturing start time) is close to the current time. It is possible to preferentially assign the work indicated by the work name.

  For example, if the worker terminal 10 can acquire manufacturing apparatus information, process information, and the like, all of the processes shown in FIG. 13 are executed on the worker terminal 10 side, and the work assignment result is directly transmitted to the worker terminal 10. It is good also as a structure output.

  When the process shown in FIG. 13 is executed and the task assignment result is notified to the administrator terminal 30, the administrator who operates the administrator terminal 30 confirms the assignment result, If the assignment result is acceptable, the assignment result is output to the worker terminal 10 of the target worker.

  In this case, a notification output by the administrator terminal 30 (or the management server device 40) is displayed on the display (lens integrated screen 1002) of the worker terminal 10. Specifically, on the display of the worker terminal 10, a message, a mark, or the like indicating which manufacturing apparatus 20 should be operated (that is, which manufacturing apparatus 20 should be directed) is displayed. This message, mark, and the like are assumed to be displayed in a partial area 1100 of the lens-integrated screen 1002 as shown in FIG. 14 in order to secure the field of view of the worker wearing the worker terminal 10. The area 1100 shown in FIG. 14 is arranged on the upper part of the lens-integrated screen 1002, but the area 1100 is provided on the lower part of the lens-integrated screen 1002 or the like if the worker's field of view can be secured. It may be.

  When the worker confirms the message or mark displayed on the lens-integrated screen 1002, the worker goes to the predetermined manufacturing apparatus 20 to perform the assigned work and performs the assigned work in a predetermined method. After confirming whether it is the device 20, the assigned work is performed. As a method for confirming whether the manufacturing apparatus 20 is to perform the assigned work, for example, a barcode including the manufacturing apparatus ID attached to the manufacturing apparatus 20 is read and displayed on the lens-integrated screen 1002. An example is a method for confirming whether or not the manufacturing apparatus ID matches.

  In the present embodiment, the position information received from the worker terminal 10 indicates the position detected by the indoor positioning sensor 14 provided in the worker terminal 10. The position of the worker terminal 10) may be estimated based on the position of an access point that can communicate with the worker terminal 10 among a plurality of access points provided in the work area 100, for example.

  In addition, the position of the worker (the worker terminal 10 worn by the worker) may be estimated by a method described later. Hereinafter, still another method for estimating the position of the worker will be briefly described with reference to FIGS. 15 and 16.

  FIG. 15 shows an example of a configuration different from the worker terminal 10 having the configuration shown in FIG. The worker terminal 10 shown in FIG. 15 has a configuration in which a gap 1001j is further provided in the worker terminal 10 shown in FIG. In addition, it is assumed that the light 2000 emitted from the light source unit 1001a provided in the worker terminal 10 includes information that can identify the worker terminal 10 (that is, a worker ID). In such a configuration, a part of the light 2000 emitted from the light source unit 1001a passes through the half mirror unit 1001c, is totally reflected by the total reflection unit 1001k, and further refracted by the emission unit 1001l, so that the gap The leakage light 2001 leaks from 1001j to the outside. That is, as shown in FIG. 16, the position of the worker is estimated by installing a plurality of sensor wireless chips W1 to W4 and the like capable of detecting the leaked light 2001 in the work area 100. More specifically, when the sensor wireless chips W1 to W4 detect the leakage light 2001, the sensor wireless chips W1 to W4 read information that can identify the worker terminal 10 included in the leakage light 2001, and read the information together with their own position information to the management server device 40. Output. According to this, even if the indoor positioning sensor 14 or the like is not provided in the worker terminal 10, the worker's position can be estimated. As a result, since it is not necessary to mount the indoor positioning sensor 14 etc. in the worker terminal 10, the cost required when manufacturing the worker terminal 10 can be reduced.

  In the present embodiment, the position in the height direction of the worker is estimated based on the atmospheric pressure (change) measured by the atmospheric pressure sensor 16 provided in the worker terminal 10, but is provided in the work area 100, for example. The estimation may be performed based on an image including a worker photographed by the camera or an image around the worker photographed by the camera 1003 provided in the worker terminal 10.

  In the present embodiment, by using a glasses-type wearable terminal as the worker terminal 10, the worker can perform a hands-free operation.

  Moreover, when the worker who wears the worker terminal 10 (glasses-type wearable terminal) has a mobile device such as a smartphone, for example, the worker terminal 10 and the smartphone may be configured to cooperate with each other. Is possible. Specifically, the worker terminal 10 and the smartphone are connected so as to be communicable by, for example, Bluetooth or the like, and the worker terminal 10 receives position information indicating a position detected by a GPS sensor provided in the smartphone from the smartphone. May be.

  Moreover, the image captured by the camera provided in the smartphone may be transmitted to the worker terminal 10 so that the image is displayed on the display of the worker terminal 10.

  Furthermore, as a configuration in which a state such as a worker moving is detected by a function of measuring the number of steps of the worker provided in the smartphone, and the detected state is transmitted to the management server device 40. Also good.

  In addition, when the worker terminal 10 has a configuration that does not have a voice call function, a voice call between the worker and the administrator may be performed using the voice call function of the smartphone.

  When the worker terminal 10 and the smartphone are linked in this manner, various functions of the smartphone can be used.

  According to the first embodiment described above, the management server device 40 manages the positional information and the manufacturing process of the manufacturing apparatus 20 installed in the work area 100, and the worker who performs the work in the work area 100. Since the configuration for managing the position information and the work availability information is provided, work assignment according to the state of the worker can be executed. As a result, conventionally, it is possible to reduce the load on the manager when assigning work.
