  Each load cone 10 is molded from a synthetic resin such as polyvinyl chloride or ABS, and has a hollow cone shape with a base portion. The load cone 10 is made of red, orange, yellow and other conspicuous colors to call attention, and a red stripe with white stripes and a black stripe with yellow stripes to improve visibility. Yes. In order to improve nighttime visibility, a reflective sheet or the like may be attached to the outer surface of the load cone 10.

  The load cone 10 is lightweight and easily moves and falls when the vehicle comes into contact. Therefore, as shown in FIG. 2, the load cone 10 includes a detection unit 11 configured to be able to detect movement or overturn accompanying the contact.

  The detection means 11 is, for example, an acceleration sensor or a contact sensor, and the load cone 10 receives acceleration exceeding a preset value, the load cone 10 is tilted beyond a preset value, When it is detected that the bottom surface of 10 is separated from the ground, an alarm signal α is output.

  Each load cone 10 further includes a transmission unit 12, a reception unit 13, a light emitting unit 14, and a control unit 15.

  The transmission unit 12 transmits the alarm signal α output from the detection unit 11 to the main transmission / reception device 20. The receiving means 13 receives the control signal β transmitted from the main transmission / reception device 20.

  The light emitting unit 14 is, for example, an array of incandescent light bulbs and light emitting diodes (LED elements). A part or the whole of the load cone 10 is formed of a light-transmitting synthetic resin, and the light emitting portion 14 disposed inside the load cone 10 is turned on and blinks, so that the outside of the load cone 10 is irradiated. . However, the light emitting unit 14 may be provided on the top surface of the top of the load cone 10 or the like.

  There are at least two types of light emission patterns: a normal light emission pattern P1 and an alarm light emission pattern P2. Here, the normal light emission pattern P1 is in a blinking state at a preset lighting interval, and the alarm light emission pattern P2 is in a lighted state.

The storage battery may be a primary battery that is replaceably attached to the load cone 10. Further, the storage battery may be a secondary battery that is charged with electric power generated by a photovoltaic power generation panel installed on the outer surface of the load cone 10.

  The main transmission / reception device 20 includes a main reception unit 21, a control signal generation unit 22, and a main transmission unit 23. The main transmission / reception device 20 may be an independent device different from the load cone 10 or may be a device built in or attached to any load cone 10.

  The main receiving means 21 receives an alarm signal α from each load cone 10.

  When the main receiving means 21 receives the warning signal α from any of the plurality of load cones 10, the control signal generating means 22 makes the light emission pattern of the light emitting portion 14 of each load cone 10 become the light emission pattern P2 for warning. A control signal β is generated.

  The main transmission unit 23 transmits the control signal β generated by the control signal generation unit 22 to all the load cones 10. However, the control signal β may not be transmitted to the load cone 10 that has already moved or overturned.

  Furthermore, as shown in FIG. 1, the vehicle intrusion warning system may be a system including a portable alarm 30 carried by a worker. Here, the portable alarm device 30 is carried by a worker located in the site area A, but the worker located in the work area near the site area A, in a place away from the site area A. A manager who is located may also be carried.

  The portable notification means 33 includes, for example, an alarm sound generation circuit and a speaker. The portable notification means 33 notifies the alarm sound when the portable reception means 31 receives the control signal β.

  Although not shown, the portable alarm device 30 includes a storage battery as a power source for the portable receiving means 31, the portable control means 32, and the portable notification means 33. The storage battery may be a primary battery that is replaceably attached to the portable alarm 30. The storage battery may be a secondary battery that is charged with electric power generated by a solar power generation panel installed on the outer surface of the portable alarm device 30.

  Next, the operation and action of the vehicle intrusion alarm system will be described with reference to the drawings.

  As shown in FIG. 1, in all the load cones 10 installed at the boundary of the site area A, the light emitting unit 14 blinks based on the normal light emission pattern P1 at the normal time.

  Here, when the vehicle enters the site area A and at least one load cone 10 moves or falls, the detection means 11 of the load cone 10 detects this and outputs an alarm signal α. This alarm signal α is transmitted to the main transmission / reception device 20 by the transmission means 12 of the load cone 10.

  When the main receiving unit 21 receives the warning signal α, the main transmission / reception device 20 generates the control signal β so that the light emission pattern of the light emitting unit 14 becomes the light emission pattern P2 for warning. The transmission means 23 transmits this control signal β toward all the load cones 10.

  The control signal β is received by the receiving means 13 of all the load cones 10, and the control means 15 of each load cone 10 performs control to change the light emission pattern of the light emitting unit 14 to the light emission pattern P2 for warning.

  Thereby, the light emission parts 14 of all the load cones 10 are switched from the blinking state to the lighting state. A field worker in a site area A demarcated by a plurality of road cones 10 sees that the road cone 10 existing around him is lit and a vehicle enters the site area A. Recognize that Thus, as described in the above-mentioned Patent Documents 1 to 3, not only the site workers in the vicinity where the device that emits an alarm sound or the like is installed, but also all site workers including the site area A and its surroundings detect the danger. can do.

  Further, in all the load cones 10, the notification means 16 that has received the control signal β notifies the alarm sound. Thereby, the field worker in the site area A hears that the road cone 10 existing around him is reporting the alarm sound, and recognizes that the vehicle has entered the site area A. Thus, as described in the above-mentioned patent documents 1 to 3, not only the site workers in the vicinity where the device that emits the alarm sound etc. is installed, but also all site workers including the site area A and its surroundings are notified by the alarm sound. Can also detect danger.

  Furthermore, all the portable alarm devices 30 are controlled by the portable control means 32, and the portable alarm means 33 notifies an alarm sound. Thereby, the site worker in the site area A hears that the portable alarm device 30 carried by himself / herself is reporting the alarm sound and recognizes that the vehicle has entered the site area A. Thus, as described in the above-mentioned patent documents 1 to 3, not only the site workers in the vicinity where the device that emits the alarm sound etc. is installed, but also all site workers including the site area A and its surroundings are notified by the alarm sound. Can also detect danger.

  In addition, when a worker who is located in a work area near the site area A or a manager who is located away from the site area A carries the portable alarm 30, these workers, management An employee can also recognize that an emergency has occurred in the field area A.

  The light emission pattern of the light emitting unit 14 may be, for example, that the normal light emission pattern P1 is in a lighting state and the alarm light emission pattern P2 is in a blinking state. Further, the normal light emission pattern P1 may be turned off, and the alarm light emission pattern P2 may be blinking or lighted. Further, the normal light emission pattern P1 may be in a blinking state, and the warning light emission pattern P2 may be in a blinking state different from the lighting interval in which the normal light emission pattern P1 is in a blinking state.

  Next, a vehicle intrusion alarm system according to a second embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 3, the vehicle intrusion warning system is a system including a plurality of road safety signs 10A and a main transmission / reception device 20A. Similarly to the first embodiment described above, this embodiment may also be a system that includes the portable alarm 30 carried by an operator.
Here, the plurality of road safety signs 10A are all road cones 10A, and, similar to the vehicle intrusion alarm system according to the first embodiment shown in FIG. It is installed at the boundary. Hereinafter, since the load cone 10A and the main transmission / reception device 20A are similar to the load cone 10 and the main transmission / reception device 20 described above, differences will be mainly described.

  Each load cone 10A includes position information γ indicating the installation position of the load cone 10 in addition to the detection means 11, the transmission means 12, the reception means 13, the light emitting unit 14, the control means 15, the notification means 16, and the storage battery described above. Holding means 17 for holding is provided.

  The position information γ may be the coordinate value of the installation position of the load cone 10A, but the area where the load cone 10A is installed, for example, the area A1 upstream of the site area A with reference to FIG. Information indicating a rough installation position, such as which area of the area A2 of the middle part, the area A3 of the downstream side, etc. belongs to, and what number it is counted from the upstream side Also good.

  Further, the holding means 17 may hold identification information unique to the load cone 10A. The identification information is, for example, a manufacturing number, an appropriately assigned number, or the like. In this case, for example, the position information γ corresponding to the identification information of the road cone 10A can be obtained by referring to reference data such as a table held in a reference data holding unit (not shown) provided in the main transmission / reception device 20A. The location information of the present invention includes such identification information.

  Further, the alarm signal α transmitted from the load cone 10A may be different according to the position information γ of each load cone 10A. The alarm signal including the position information of the present invention includes an alarm signal α that varies depending on the position information γ.

  The transmission unit 12 transmits an alarm signal α including the position information γ to the main transmission / reception device 20A. This alarm signal α is received by the main receiving means 21 of the main transmitting / receiving apparatus 20A.

  The control signal generation means 22A of the main transmission / reception device 20A generates the control signal β based on the received alarm signal α and the position information γ included therein.

  For example, as shown in FIG. 4, the installation position of the moved or overturned load cone 10 </ b> A (s) (where 1 ≦ s ≦ l) is the area A <b> 1 upstream of the site area A from the position information γs. In the case shown, the control signal generating means 22A generates a control signal β1 such that the light emitting unit 14 emits light with the light emission pattern P2A for medium warning.

  On the other hand, although not shown, the installation position of the moved or fallen load cone 10A (t) (where l + 1 ≦ t ≦ m) is the central area A2 of the site area A from the position information γt (see FIG. 4). Is displayed, the control signal generation unit 22A generates a control signal β2 that causes the light emitting unit 14 to emit light with the severe alarm light emission pattern P2B. On the other hand, it is indicated that the installation position of the moved or overturned load cone 10A (u) (where m + 1 ≦ u ≦ n) is the area A3 (see FIG. 4) downstream of the site area A from the position information γu. In this case, the control signal generation unit 22A generates a control signal β3 such that the light emitting unit 14 emits light with the light emission pattern P2C for light warning.

  The control signals β1 to β3 generated by the control signal generation unit 22A are transmitted to all the load cones 10A (1) to 10A (n) by the main transmission unit 23. The light emission patterns P2A to P2C are all different such that the blinking intervals are different from each other and the illuminance is different from each other.

  Thus, since the light emission patterns P2A to P2C are different depending on the degree of danger, the field worker can recognize the degree and take appropriate measures.

  In addition, it is not limited to what transmits the same control signal (beta) to all the load cones 10A (1) -10A (n). For example, the control signal β may not be transmitted to the moved or fallen load cone 10A (s).

  Furthermore, according to the control signals β1 to β3, the warning sound pattern notified by the notification unit 16 of the load cone 10A and the portable notification unit 33 of the portable notification device 30A may be made different. Thereby, the field worker can recognize the degree of danger from the warning sound. Further, for example, the control signal β may not be transmitted to the load cone 10A and the portable alarm device 30A located in the area A3.

  Moreover, the modification of the vehicle intrusion warning system which concerns on the 2nd Embodiment of this invention demonstrated below may be sufficient.

  In the first modification, as shown in FIG. 5, when the installation position of the moved or overturned load cone 10A (s) is indicated by the position information γs to be the area A1 upstream of the site area A, The control signal generating means 22A generates a control signal β1 such that the light emitting part 14 emits light with a light emission pattern P2A for a medium warning, and the main transmission means 23 outputs the control signal β1 to the central area of the site area A. The data is transmitted to the load cones 10A (l + 1) to 10A (m) installed in A2.

  At the same time, the control signal generating means 22A generates a control signal β2 that causes the light emitting section 14 to emit light with the light emission pattern P2B for severe warning, and the main transmission means 23 sends the control signal β2 upstream of the site area A. This is transmitted to the load cones 10A (1) to 10A (l) installed in the side area A1. Further, the control signal generating means 22A generates a control signal β3 such that the light emitting part 14 emits light with the light emission pattern P2C for light warning, and the main transmitting means 23 sends this control signal β3 to the downstream side of the site area A. To the load cones 10A (m + 1) to 10A (n) installed in the area A3.

  Thus, since the light emission patterns P2A to P2C of the road cone 10A are different depending on the degree of danger at the installation position of the load cone 10A, each field worker has the light emission patterns P2A to P2C of the load cone 10A located nearby. Therefore, it is possible to take appropriate measures accordingly.

  Further, the same control signal β is generated when one load cone 10A is moved or tilted and when the plurality of load cones 10A are moved or tilted, and the light emitting unit 14 emits light with the same warning light emission pattern P. It is not limited to things.

  Further, as shown in FIG. 3, each portable alarm device 30 </ b> A may include a portable position information acquisition unit 34 in addition to the portable reception unit 31, the portable control unit 32, and the portable notification unit 33.

  The portable position information acquisition unit 34 acquires the position information of the portable alarm device 30A using, for example, a GPS (global positioning system) function built in a mobile phone or a smartphone.

  And when the position of the portable alarm device 30 indicated by the position information acquired by the portable position information acquisition means 34 exists in any of the areas A1 to A3 of the site area A, which area A1 to A3 is located? Accordingly, it is preferable to change the warning sound pattern notified by the mobile notification means 33 of the mobile alarm device 30. Thereby, the field worker can recognize the degree of danger according to the position from the warning sound.

  In addition, when the main transmitter / receiver 20A can acquire the position information of the portable alarm device 30A, depending on whether the position of the portable alarm device 30 indicated by the position information exists in any of the areas A1 to A3. Then, the main transmission means 23 transmits any one of the control signals β1 to β3, and the portable control means 32 of the portable alarm device 30 controls the portable notification means 33 in accordance with the control signals β1 to β3, and the warning sound pattern May be different.

  It can be considered that the degree of danger is higher when a large number of road cones 10A move or tilt than when one load cone 10A moves or tilts because the vehicle that has collided with the road cone 10A is running away. .

  Therefore, in the second modification, when the alarm signal α is received from a preset number, for example, two or more than five load cones 10A, the control signal generating unit 22A of the main transmission / reception device 20A A control signal β1 is generated so that the light emitting unit 14 emits light with the warning light emission pattern P2B, and the main transmission unit 23 transmits the control signal β1 to all the load cones 10A.

  As described above, when the number of the moving or inclined road cones 10A is large and there is a high risk of danger, the road cones 10A emit light with the light emission pattern P2B for severe warning. It becomes possible.

  Furthermore, it is preferable to transmit the control signal β1 to the portable alarm device 30A. In this case, the portable alarm device 30A that has received the control signal β1 is controlled by the portable controller 32 so that the portable alarm device 33 notifies the warning sound for a severe alarm. As a result, the on-site staff can respond appropriately from the warning sound.

  Furthermore, in the third modified example, the control signal generating unit 22A generates the control signal β according to the combination of the installation position and the number of the load cones 10A that have moved or fallen. In this case, for example, a combination of the first modification and the second modification may be used.

  Further, for example, weight coefficients μ1 to μn indicating the degree of danger corresponding to the installation positions indicated by the respective position information λ1 to λn of the respective load cones 10A (1) to 10A (n) are determined in advance and moved or fallen. A control signal β corresponding to a range divided by a predetermined threshold, to which the sum of the weighting factors μ of the load cone 10A applies, is applied to all the code cones 10A or the load cones 10A located in an area corresponding to the range. You may send it.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this.

  For example, in the embodiment, the case where the vehicle intrusion alarm system is a system including a plurality of road cones 10 and 10A and main transmission / reception devices 20 and 20A has been described. However, the present invention is not limited to this, and the main transmission / reception devices 20 and 20A may not be provided.

  In this case, for example, the alarm signal α output from the detection means 11 of the moved or inclined load cone 10, 10A is transmitted from the transmission means 12 to all other load cones 10, 10A. The alarm signal α is input to the control signal generating means provided in each of the load cones 10 and 10A, where the control signal β is generated, and the control signal β is emitted. It may be input to the unit 14.
