The case where is pressed is shown.

In the case of FIG. 2A, the IC tag reader / writer 15 reads the information of the work specifying IC tag 30 and transmits it to the control device 12. The data editing unit 16 of the control device 12 associates data of “when”, “where”, “who”, “what”, and “how” with each other and stores them in the storage unit 18 (see FIG. 1). . Specifically, the data D301 includes the time (time stamp) read by the IC tag reader / writer 15, the location ID, the instruction ID (the page ID of the work drawing is “000”), and the start of the work content. It is information to the effect. The information of “who” is unknown (?). The location ID is information for specifying the location of the cell work terminal 10 stored in the storage unit 18 in advance.

In the case of FIG. 2B, the IC tag reader / writer 15 reads the information of the worker specifying IC tag 40 and transmits it to the control device 12. The data editing unit 16 of the control device 12 associates the data of “when”, “where”, “who”, “what”, and “how” with each other and stores them in the storage unit 18. Specifically, the data D401 is information of time (time stamp), place ID, and worker ID read by the IC tag reader / writer 15. Here, the information of “what” and “how” is unknown (?).

In the case of FIG. 2C, the data editing unit 16 of the control device 12 associates data of “when”, “where”, “who”, “what”, “how” with the storage unit 18. (See FIG. 1). Specifically, the data D131 includes the time when the switch 13 is pressed or the time when the control device 12 receives the pressing signal, the location ID, the instruction ID (including the page ID of the work drawing at the end of work), and the work content. It is information to the effect of end. The information of “who” is unknown (?).

The data editing unit 16 of the control device 12 edits work transmission data including 4W1H information. The process of editing work transmission data means that when the data D301 and the data D401 are prepared, the worker ID that is lacking is added to the data D301, the time when the data is prepared, and the encryption ID that is a unique ID. (Identification information) is added to create the data D340 and store it in the storage unit 18.

Or, for example, when the data D401 is stored first and the data D301 is received, or when the data D301 and the data D401 are ready, the missing instruction ID and work content information are added to the data D401. The data D340 is generated by adding the time when the data are collected and the encryption ID (identification information) that is a unique ID, and stored in the storage unit 18.

In the case of data D131, work transmission data may be created in association with data D401 and data 131, or data D341P (not shown) which is work transmission data in association with data D340 and data D131. May be created.

In order to determine the case where the data D301 and the data D401 are prepared, the location ID may be associated with the key, or a time within a predetermined time range may be associated with the key.

The data dividing unit 17 of the control device 12 divides the data D340 according to the transmission schedule. In the present embodiment, the data division means that a part of the data is illegally acquired and is sent to a data state that has no meaning as a whole.

Specifically, as shown in FIG. 2, when the data dividing unit 17 transmits the data D340, which is work transmission data, to the work performance management apparatus 20, the data division unit 17 obtains the time, the encryption ID, and the IP (Internet Protocol) header. Data D341 (first transmission data (when)) is associated with each other, location ID, encryption ID, and IP header are associated with each other as data D342 (second transmission data (where)), worker ID, encryption ID, and IP The header is associated with data D343 (third transmission data (who is)), the instruction ID, encryption ID, and IP header are associated with each other as data D344 (fourth transmission data (what)). The work transmission data is divided as data D345 (fifth transmission data (how)) by associating the encryption ID with the IP header, and the divided data is transmitted to the work result management apparatus 20 That. The IP header includes a transmission destination IP address, a transmission source IP address, and the like.

When the data restoration unit 22 of the work performance management apparatus 20 receives the divided data, the data restoration unit 22 stores the data in the storage unit 23 and data D341 and data D342 which are data divided based on the encryption ID (identification information). Based on the data D343, data D344, and data D345, the data D340, which is work transmission data, is restored and stored in the storage unit 23.

In the present embodiment, the work transmission data is divided into only the data with the minimum content and transmitted, thereby providing a work performance collection system with high security against unauthorized acquisition. In addition, when transmitting, each data is transmitted as randomly as possible, so that the work performance collecting system with higher security against unauthorized acquisition can be obtained.

Note that it is generally known that data is divided and transmitted as packet communication on the Internet. MTU (Maximum Transmission Unit) is defined for the communication line. The MTU is the maximum transfer unit and is the data length divided within the maximum transfer unit that can be transferred. Since the MTU is determined for each communication line, packet fragmentation (division processing) is performed when a communication path having an MTU smaller than the packet length is passed along the path.

In this embodiment, unlike packet communication considering transfer units, only minimum information is transmitted to a normal MTU for passing through a communication path. Moreover, the data D341, D342, D343, D344, and D345 described above are meaningful in the transmission frequency for each data, and can be regarded as information that is frequently performed at a certain IP address. For this reason, it is one of the features that the data is meaningful from the viewpoint of the administrator.
