Referring to Figures 2 and 4 will be described in the danger zone access prohibition monitoring operation.

The terminal 30 'further includes a safety module 37, which is fixedly installed in a danger zone (cliff, a puddle, a cliff, etc.) in a construction site, or is fixed in a driver's seat or outside of heavy equipment (excavator, forklift, etc.) or by a driver. You can also carry it. The safety module 37 outputs the worker information and the warning signal of the tag 10d 'when the tag 10d existing outside the preset recognition range 30'a of the reader enters the recognition range 30'a. Transfer to 32. The reader's recognition range is adjustable, and the reader's recognition range is appropriately adjusted according to the site situation in case of the reader mounted in the terminal used for prohibition of dangerous zone access. For example, if the terminal is installed in heavy equipment such as an excavator or forklift, the reader's recognition range may be adjusted with a slight margin than the working radius of the heavy equipment to be installed. The output module 32 displays the received worker information on the screen and warns the approaching worker using sound and flickering of the screen in response to the warning signal. The output module 32 may further include a siren and a warning lamp, and may transmit a warning signal more reliably and clearly by using a siren and a warning lamp operated by the warning signal. In addition, the safety module 37 may transmit the worker information of the worker approaching the danger zone to the server 20 through the communication module 35 to use as a material for safety training or to reflect the work attitude to evaluate the work attitude. .

Next, the emergency call operation will be described.

The tag 10 'further includes an emergency call button 11, and the terminal 30' further includes an emergency call module 38, when the worker is injured during work or in an urgent situation. When the emergency call button 11 is pressed, an emergency call signal is transmitted, and the emergency call module 38 receives an emergency call signal and transmits worker information, location information, and emergency information to the output module 32. In the case of the emergency call signal is transmitted to all the terminals capable of wireless communication with the corresponding tag located nearby. The output module 32, which has received the emergency information, emits a warning sound and displays on the screen that an emergency has occurred. In addition, the worker information and location information of the emergency call worker is displayed on the screen to enable a quick rescue.

5 is a reference diagram for explaining the operation attitude evaluation operation according to the present invention. The operation attitude evaluation operation will be described with reference to FIGS. 2 and 5.

The terminal 30 'further includes a GPS module 39, and can always check the current position of the terminal through the GPS module 39. Positioning through GPS is a well-known technique, so a detailed description thereof will be omitted. In the case of the terminal 30 ′, there is always a possibility that the position of the manager or worker is portable. Referring to FIG. 5, the terminal 30 ′ has a predetermined recognition range 30 ′ a1 by the reader 33 mounted therein. As the terminal 30 'moves, the recognizable range of the terminal 30' moves as well. In FIG. 5, after the terminal 30 'moves to the left side, the recognition range of the moved terminal 30'1 moves. 30'a2 also moves to change. In this case, even if the worker is working without leaving the workplace according to the movement of the terminal, it may be displayed as being out of the workplace due to the movement of the manager having the terminal, which may be disadvantageous to the worker. In the case of Figure 5 there are a plurality of tags (10e, 10f, 10g, 10h, 10i, 10j) located in the workplace, but in the case of the tag (10e) possessed by a specific operator due to the movement of the terminal is shown as leaving the workplace Worker information is transmitted to the server 20 and recorded. In such a case, in order to reduce the disadvantages received by the worker, the moving range of the terminal is constantly limited to set the reference range 30's so that the worker information of tags recognized only when the terminal is located within the reference range is used as a valid value. It is taken and displayed on the terminal and sent to the server. If the location of the terminal is out of the reference range, the worker information of the tag recognized by the terminal is not stored in the terminal or the server. Whether the terminal is located within the reference range is determined by referring to the current position identified by the mounted GPS. In addition, by limiting the moving range of the terminal within the reference range, the recognition range 30'a3 in which the terminal takes a valid value also increases.

As described above, in order to reduce the disadvantages caused by the worker's departure from the workplace caused by the movement of the terminal, and to collect and grasp more reliable work attitude data, the reference number is set to set the reference number of the worker's workplace departure. If exceeded, it may be determined that the worker has left the workplace. In the case of the reference number, the number of workplace departures of the worker is determined by repeated experiments in the actual site, and when the specific number is exceeded based on the specific number of times, if the worker has actually left the workplace, the specific number is referred to as the reference number. You can decide. In the case of the reference frequency, although it is determined by the actual experiment in the workplace, it can be used as a reliable value although it is not perfect. The server 20 compares the reference number with the number of workplace departures of the worker, generates a time and attendance signal when the number of departures exceeds the reference number, and stores the worker information of the worker. Based on the stored worker information, the manager can evaluate the worker's work attitude and determine whether to re-employ.

All information obtained from the terminals 30 and 30 'described above are transmitted to the server 20 and stored in the DB, and the senior manager or the personnel manager can evaluate the work attitude of each worker and the time and number of workplace departures. It is possible to accurately pay wages by grasping the situation, to find out where the vulnerable areas are located in the workplace, to take safety measures, and to select workers who frequently approach the danger zones and conduct special safety education to prevent accidents. You can also prevent.

In addition, the tag and the reader use 2.45MHz as the communication frequency to configure the system, and the recognition distance, recognition rate, high cost of system configuration, The inconvenience of system expansion and the large size of the terminal and the tag can overcome the lack of portability.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary skill.
