  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an entire configuration of an LED equipped helmet 20 according to an embodiment of the present invention. Referring to FIG. 1, the LED helmet 20 includes a terminal mounting 10 capable of detecting an external trigger signal and an LED 18 connected to the terminal mounting 10.

  The terminal mounting 10 includes a CPU 11 for controlling the entire terminal mounting, a receiving unit 12 connected to a trigger antenna 13 for detecting a trigger signal, and a transmitting unit 14 connected to a transmitting antenna 15 for transmitting data etc. to the outside. It includes an LED control unit 16 that controls the light emission color of the LEDs 18 and 19 in accordance with the signal received by the receiving unit 12. Here, the trigger signal is a magnetic field signal.

  The LED control unit 16 changes the emission color of the LED according to the content of the trigger signal received by the receiving unit 12. In this embodiment, the trigger signal differs depending on the area. For example, a signal indicating that the area is a danger area in the danger area is output, and a signal indicating that the area is a safety area is output in the safety area.

  Next, the appearance of the LED equipped helmet 20 will be described. FIG. 2 is a view showing the appearance of the LED equipped helmet 20. As shown in FIG. Referring to FIG. 2, the LED helmet 20 includes a helmet 20 a and a belt-like mounting portion 20 b attached to the outer periphery of the helmet 20 a. The mounting portion 20b is provided with a white LED 19 provided at the front end of the helmet 20a, a terminal device 10 provided on the side of the white LED 19, and an LED 18a provided with a plurality of light emission colors provided along the belt. An LED 18b connected to the terminal device 10 is provided inside the front end of the helmet 20a.

  The LED 18a is visible from the surrounding people and the monitoring wearing, and the LED 18b is visible to the wearer of the LED helmet 20.

  Next, the operation state of the LED equipped helmet 20 will be described. FIG. 3 is a view showing a specific operating state. Referring to FIG. 3, CPU 11 causes LED control unit 16 to emit light from LEDs 18 a and 18 b in response to a trigger signal from the outside.

  Specifically, referring to FIG. 3, the danger area trigger signal transmission source 22 outputs a predetermined trigger signal (magnetic field) as the danger area 21. Here, the trigger signal is indicated by a circle. When the worker 25 wears the LED helmet 20 and is in the danger area, the terminal device 10 determines that the signal received by the receiving unit 12 is the danger signal by the CPU 11. At this time, the LED control unit 16 causes the LEDs 18a and 18b to light up in red. Also, since the LED 19 is for illumination on the front, it is basically white.

  By this, the worker 25 can recognize that he / she is in the danger area, and can take a risk avoiding action.

  On the other hand, when the worker 25 wears the LED helmet 20 and is out of the danger area (right side in FIG. 3), the receiver 12 does not receive the danger signal, so the LED controller 16 responds to the LED 18 Does not indicate light emission. Therefore, the LEDs 18a and 18b do not emit light. For example, the light may be emitted in green.

  A caution area may be set as an area between the inside of the danger area and the outside of the danger area. In this case, the worker can know that he / she is in the area to be careful.

  In addition to the color to be emitted, the emission timing may be changed, or a predetermined sound may be generated. In particular, in the danger area, it is preferable to not only light up in red but also to make it blink more in red.

  In this way, it is possible to monitor the worker himself and his surroundings by using the worker wearing the LED helmet 20, the person around it, and the monitoring attachment not shown.

  The caution area and the danger area are used, for example, to notify the work area when a worker works in an area where heavy equipment such as a forklift is operating.

  Moreover, although the case where LED18a, 18b was attached to the helmet 20a was demonstrated here, LED may be attached not only to this but to the vest which a worker wears, and this may be lighted.

  Also, the danger area trigger signal transmission source 22 may have an ID identifying the danger area trigger signal transmission source 22. Also, the color may be different for each ID. Then, the worker wearing the LED helmet 20 can know the reason why he / she is located in the dangerous area.

  Next, another embodiment of the present invention will be described. 4 shows an example in which a warning area 32 is provided around the danger area 30 with respect to the embodiment of FIG. 3 (FIG. 4 (A)), and a safety area 34 is provided inside the danger area 36. It is a figure (Drawing 4 (B)) showing an example at the time of providing. In any case, the danger area trigger signal sources 31, 37, the warning area trigger signal source 33, and the safety area trigger signal source 35 are provided in the center of each area, as in the previous embodiment. It is.

  The danger area trigger signal source 31 and the warning area trigger signal source 33 alternately transmit from the same signal source at a predetermined time interval, and when the trigger signal ID of the danger area is detected, priority is given to the warning area trigger signal source etc. Make a judgment.

  Referring to FIG. 4A, in this case, the LED may emit light in yellow, for example, as the warning area 32. Further, referring to FIG. 4B, when a safety zone or the like is provided in the danger area 37, for example, the danger area 37 emits light in red and the safety area 34 emits light in green in its inside. Do.

  The contents of the lighting control of the LED control unit 16 performed by the CPU 11 of the terminal device 10 when the above embodiments are summarized will be described with reference to the flowchart shown in FIG. Referring to FIG. 5, the receiver 12 receives a trigger signal from the trigger signal source (step S11, hereinafter, step is omitted), and controls the lighting content of the LEDs 18a and 18b according to the content.

  That is, if the trigger signal is not received (or if it is a safety area), the LEDs 18a and 18b do not light up or light up green (S12). If a trigger signal indicating that the area is a danger area is received, it turns red or blinks as a danger signal (S14).

  If a trigger signal indicating that it is a warning area is received (Warning area in S11), it is determined whether it was a warning area last time (S14). If it is determined that the previous warning area is also the warning area (YES at S14), it turns yellow as a warning signal (S15), and if the previous time is not a warning area (NO at S14), it lights red as a danger signal (S16) .

  Such control is performed because, as shown in FIG. 4, the warning and the danger warning range are wider than the danger, and the danger and the warning are alternately performed in the danger area. That is, there is time in the area that must be at risk, which is a warning. In terms of color, red lighting and yellow lighting appear alternately, and in high-speed, afterglow will be orange to the human eye. In order to prevent this, a warning is detected and the previous state emits a red color which is the color of danger if it is dangerous.

  Here, although the case where the warning area and the danger area overlap is described, the present invention is not limited to this, and it is preferable to make this determination in the area where normal conditions overlap as in the case of the safety area and the danger area.

  Next, the shapes of the danger areas 34a and 34b and the safety area 36 will be described. FIG. 6 is a diagram showing this shape. FIG. 6A is a plan view, and FIG. 6B is an arrow view of a portion indicated by arrows VIB-VIB in FIG. 6A. In FIG. 6 (B), the center horizontal line indicates the plane on which the trigger signal source is placed, not shown.

  Referring to FIG. 6A, the danger areas 34a and 34b and the safety area 36 are elliptical in shape having a linear portion in a longitudinal direction in plan, but are oval in the vertical direction.

  In addition, this shape can be made arbitrary shapes including circular shape by the shape and output intensity of a trigger signal source.

  In addition, the trigger signal source may be held by a heavy machine such as a tire roller, and the work environment of the worker may be clearly indicated by setting the moving range as a dangerous area.

  Next, a method of dividing each area will be described as an embodiment of the present invention. Here, a trigger signal generator as described in Japanese Patent No. 5512906 is used as the setting of the detection area of the worker.

  FIG. 7 is a view showing a state where the detection area is separated by using two trigger signals, which is described as FIG. 17 of this patent 5512906. As shown to FIG. 7 (A) and FIG. 7 (B), only the trigger signal of one side is output to the mounting position of two trigger antennas, and the trigger signal which can not detect the other side is output.

  By providing the trigger coil in this manner, as shown in FIG. 7, the X-axis direction (direction shown by the arrow in the figure) is divided into two detection areas (ID1 and ID2) centering on the installation position of the trigger antenna. Similarly, it is also possible to divide the Y-axis direction into two detection areas centering on the installation position of the trigger antenna.

  As a result, it becomes possible to detect only a predetermined area (a portion shown by oblique lines in the figure).

  In the above-mentioned embodiment, although the case where the luminescent color of the LED of the helmet with the LED worn by the worker is lit in different colors according to the trigger signal indicating the area where the worker is located has been described, Alternatively, the ID of the terminal device 10 may be detected at the trigger signal source so that it can be recorded or displayed.

  Furthermore, an acceleration sensor or the like may be attached, and a worker wearing a helmet with an LED may be notified that a danger has been recognized when hitting the helmet by a change in color of the LED.

  Furthermore, since it is possible to remotely know which portable radio terminal has invaded which trigger signal source (dangerous point) from the signal transmitted from the terminal device, safety point elimination, notification by stop or alarm, etc. Measures such as sending security guards become possible.

  Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiment within the same or equivalent scope of the present invention.

  10 terminal equipment, 11 CPU, 12 reception units, 13 reception antennas, 14 transmission units, 15 transmission antennas, 16 LED control units, 18, 19 LEDs, 20 helmets with LED, 21 danger areas, 22 danger area trigger signal sources.
