FIG. 6 is a diagram showing a data processing flow on the pre-processing yard 5 (first yard) side in the labor monitoring system according to the embodiment of the present invention.

  When data processing on the pre-processing yard 5 (first yard) side is started in step S100, the process proceeds to step S101, and ID information of the active RFID tag 100 detected by the RFID reader 112 is read. In step S102, a log in which the ID information and the time information are associated is recorded in the first yard log recording unit 72. Note that the time information uses time measuring means (not shown) provided in a personal computer or the like. In step S103, it is determined whether or not the system is terminated. When the determination result is NO, the process returns to step S101, and when it is YES, the process proceeds to step S104 and the process is terminated.

  FIG. 8A shows an example of data acquired by the data processing of FIG. 6 as described above. FIG. 8A is a conceptual diagram of information recorded in the first yard log recording unit 72 of the labor monitoring system according to the embodiment of the present invention. For example, the active RFID tag 100 periodically transmits at a period of, for example, a 6-second interval. According to the data processing as described above, when the RFID reader 112 detects this, the active RFID tag 100 at each time point. And is stored in the first yard log recording unit 72. In the example shown in FIG. 8A, the ID information (ID = 000001, 000003, 000004...) Detected in the pre-processing yard 5 (first yard) and the time information of the detected moment (◯ in the figure). Is a conceptual diagram in which log data is recorded.

FIG. 7 is a diagram showing the flow of data processing on the side of the stacked production yard 10 (second yard) in the labor monitoring system according to the embodiment of the present invention. FIG. 8B shows an example of data acquired by the data processing of FIG. FIG. 8B is a conceptual diagram of information recorded in the second yard log recording unit 73 of the labor monitoring system according to the embodiment of the present invention.

  In step S200, when data processing on the stacked production yard 10 (second yard) side is started, the process proceeds to step S201, and the ID information of the active RFID tag 100 detected by the RFID reader 122 is read. In step S202, a log in which the ID information and the time information are associated is recorded in the second yard log recording unit 73. Note that the time information uses time measuring means (not shown) provided in a personal computer or the like. In step S203, it is determined whether or not the system is terminated. When the determination result is NO, the process returns to step S201, and when it is YES, the process proceeds to step S204, and the process is terminated.

  FIG. 8A shows an example of data acquired by the data processing of FIG. 6 as described above. FIG. 8A is a conceptual diagram of information recorded in the second yard log recording unit 73 of the labor monitoring system according to the embodiment of the present invention. For example, the active RFID tag 100 periodically transmits at a period of, for example, 6 seconds. According to the data processing as described above, when the RFID reader 122 detects this, the active RFID tag 100 at each time point. And is stored in the second yard log recording unit 73. In the example shown in FIG. 8A, the ID information (ID = 000003, 000007, 000011...) Detected in the stacked production yard 10 (second yard) and the time information at the detected moment (◯ in the figure). Is a conceptual diagram in which log data is recorded.

  According to the labor monitoring system of the present invention as described above, the transmission of the active RFID tag is detected by the RFID reader, and the log in which the ID information of the active RFID tag and the time information are associated with each other is recorded in the first or Since the data is recorded in the second yard log recording unit, manual input work or the like is not required, labor performance measurement can be automatically performed, and labor data can be easily acquired.

  By the way, even if a log exists in the first yard log recording unit 72 or the second yard log recording unit 73, if the log does not remain for a certain period of time, the active RFID tag from which the log has been acquired It is considered that the owners of are not engaged in work. In addition, depending on the work position of the worker, it is within the detection range of both the pre-processed yard detection antenna 110 and the stacked production yard detection antenna 120, and logs to both the first yard log recording unit 72 and the second yard log recording unit 73. In this case, if the worker is working in any yard and does not organize it rationally, it will not make sense as labor data. Therefore, in the labor monitoring system according to the present invention, based on the log information acquired by the first yard log recording unit 72 and the second yard log recording unit 73, the determination process of the existence of the owner of the active RFID tag is performed. ing.

  Next, the existence determination process as described above based on the log information acquired by the first yard log recording unit 72 and the second yard log recording unit 73 will be described. FIG. 9 is a diagram showing a flowchart of the existence determination process in the labor monitoring system according to the embodiment of the present invention. Such presence / absence determination processing is periodically executed after a log is acquired over a predetermined period. For example, after all the work for one day is completed, the existence determination process may be performed for the log of the work for the day.

In FIG. 9, when the existence determination is processed in step S300, the process first proceeds to step S301, and ID = 000001 is set as the variable ID. Subsequently, in step S302, the first
ID (variable) log information is acquired from the yard log recording unit 72, and ID (variable) log information is acquired from the second yard log recording unit 73 in step S303. In step S304, when there is a log in both the first yard log recording unit 72 and the second yard log recording unit 73, processing is performed so that the log information in the first yard log recording unit 72 is given priority.

  In step S305, the log information of the first yard log recording unit 72 includes a log of 2 points or more, and there is no skipping of log data of a predetermined value or more and exceeds a predetermined time (for example, about 10 minutes). It is determined whether or not there is a log in the one-yard log recording unit 72. If the determination result in step S305 is YES, the process proceeds to step S306, and if NO, the process proceeds to step S309.

  In step S306, it is determined that the owner of the active RFID tag 100 having the ID (variable) exists in the pre-processing yard 5 (first yard). In step S309, the log information of the second yard log recording unit 73 includes a log of two or more points, no log data exceeding a predetermined value, and exceeding a predetermined time (for example, about 10 minutes). Whether or not there is a log in the second yard log recording unit 73 is determined. When the result of the determination in step S309 is YES, the process proceeds to step S310, and when it is NO, the process proceeds to step S311.

  In step S310, it is determined that there is an active RFID tag 100 holder with the ID (variable) in the stacked production yard 10 (second yard). In step S311, the log information of either the first yard log recording unit 72 or the second yard log recording unit 73 includes a log of two or more points, no log data exceeding a predetermined value, and a predetermined value. It is determined whether there is a log that does not exceed the time (for example, about 10 minutes). If the determination result in step S311 is YES, the process proceeds to step S312; if NO, the process proceeds to step S315.

  In step S312, it is determined whether or not the log of interest in step S311 was in a yard different from the current one. When the result of the determination in step S312 is YES, the process proceeds to step S314, where it is determined that it exists in the yard that existed before the target log, and when the result of the determination is NO, the process proceeds to step S313. It is determined that the log exists in either the first yard or the second yard.

  In step S315 which proceeds when NO is determined in step S311, it is determined that neither the first yard nor the second yard exists.

  In step S307, it is determined whether or not the confirmation process has been completed for all logs of ID (variable). When the determination result is NO, the process returns to step S302, and when the determination result is YES, the process proceeds to step S308. In step S308, it is determined whether or not the confirmation process has been completed for all IDs (variables). If the determination result is NO, the process proceeds to step S316, the ID (variable) is incremented by 1, and the process returns to step S302. If the determination result is YES, the process proceeds to step S317 to end the process.

FIG. 10 is a diagram for explaining existence confirmation in each yard by log data and existence confirmation processing. In both FIG. 10A and FIG. 10B, log data with ID = 000003 and presence determination information are shown as an example, and the first row is a log recorded by the first yard log recording unit 72 The data (○ point data) is shown, the second row shows the existence confirmation information (black line part) in the pre-processing yard 5 (first yard) based on the log data, and the third row shows the second The log data (○ point data) recorded in the yard log recording unit 73 is shown, and the fourth level shows the existence confirmation information (black line part) in the stacked production yard 10 (second yard) based on the log data. ing.

10 (A) and 10 (B), the worker works in the layered production yard 10 (second yard) during the period (I), then works in (II), and again ( III
) Shows the relationship between the log data and the existence determination information when the work is performed. According to the processing of the flowchart as shown in FIG. 9, when the period of (II) exceeds the predetermined time, the worker does not pre-process during the period of (II) as shown in (A). It is determined that it was present in the processing yard 5 (first yard). On the other hand, in the case where the period of (II) does not exceed the predetermined time, as shown in (B), for the period of (II), the worker had a layered production that existed before that. It is determined that it was present in yard 10 (second yard).

  As described above, in the labor monitoring system according to the present invention, based on the log information acquired by the first yard log recording unit 72 and the second yard log recording unit 73, the determination process of the presence / absence of the owner of the active RFID tag is performed. Therefore, even if there are a plurality of yards, it is possible to acquire effective labor data in which the worker's location is determined.

  Next, an example of a user interface screen in the labor monitoring system of the present invention will be described.
