  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram of a port facility to which a port management system according to an embodiment of the present invention is applied.

  As shown in FIG. 1, the harbor management system according to an embodiment of the present invention can detect the presence of a plurality of quay ladders 1 installed on the side wall 1001 of the quay wall 100 and a person in the vicinity of the quay ladder 1. Harbor facility building that collectively manages the detection signals transmitted from the quay ladder system 10 and the transmission device 5, each of which includes a plurality of human detection sensors 2 and a transmission device 5 that transmits detection signals from the human detection sensors 2. 60 and a management unit 6 in the network.

  According to the harbor management system having the above configuration, the human sensor 2 capable of detecting the presence of a person in the vicinity of the quay ladder 1 installed on the side wall 1001 of the quay 100 of the harbor is provided. When the human sensor 2 detects the presence of a person, a detection signal is transmitted from the transmission device 5 to the management unit 6.

  In this way, the human sensor 2 can manage the intrusion of a person from the quay ladder 1 day and night, and a plurality of quay ladders 1 are blind spots from the port facility building 60 (management unit 6). Even if it is provided in the place, since it can be collectively managed by the management unit 6, it is possible to reduce the cost and human labor, and to further improve the safety of the port.

  In the present embodiment, the human sensor 2 is provided in each of the plurality of quay ladders 1, and the quay ladder 1 and the human sensor 2 are configured in a one-to-one correspondence. Therefore, by identifying the human sensor 2 that has detected the presence of a person, it is possible to more easily and directly grasp which quay ladder the intruder has used.

  The transmission device 5 is also configured to transmit the detection signal to a predetermined mobile terminal 7. In this case, the detection signal is also transmitted to the predetermined portable terminal 7 by the transmission device 5. Therefore, even if the administrator 70 is away from the management unit 6, it is possible to notify the administrator 70 of the presence of the intruder.

  Furthermore, the transmission device 5 is configured to be capable of wireless transmission. In this case, since it is not necessary to provide a signal transmission path, this system can be easily constructed in an existing port (facility).

  Here, the ladder system 10 for a quay according to this embodiment will be described more specifically. 2 and 3 are construction state diagrams in the vicinity of a quay ladder used in the harbor management system of FIG. It is a construction state figure to the quay of the ladder for quay walls concerning one embodiment of the present invention. FIG. 2 is a view of the quay ladder as seen from the front (sea side), and FIG. 3 is a view of the quay ladder as seen from the side. 4 is a cross-sectional view taken along line XX in FIG.

  According to the quay ladder system 10 of the present embodiment, the human sensor 2 is installed on the quay ladder 1 installed on the side wall 1001 of the quay 100. On the other hand, the alarm device 3 and the transmission device 5 are installed on the ground 1002 which is the ground portion of the quay 100 near the quay ladder 1. When the presence sensor 2 detects the presence of a person, the transmission device 5 transmits a detection signal and the alarm device 3 issues an alarm.

  As shown in FIGS. 2 and 4, in this embodiment, the quay ladder 1 is integrally formed with a pair of side columns 11 formed of a thick cylindrical elastic material and an elastic material of the same quality as the elastic material. And a plurality of horizontal rails 12 fixed to each other by connecting the side pillars 11 at a predetermined interval.

  The side column 11 of the present embodiment has a hollow portion 14 and is fixed to the side wall 1001 of the quay wall 100 via the mount 4 by a stud bolt 16. In order to facilitate the construction work at this time, a construction hole 15 is formed in front of the side pillar 11. As for the length of the side pillar 11 (that is, the length of the ladder body 1), the side pillar 11 having an appropriate length is prepared according to the height of the sea surface 200 in the attached quay 100 or the like. More specifically, for example, it is installed so that the cross rail 12 is positioned from the height of the sea level 200 at the time of low tide to a predetermined length downward. In addition, as shown in FIG. 3, when the lower part of the quay wall 100 is not flat, it is good also as attaching and extending the joint type ladder 18 to the lower end of the ladder main body 1. FIG.

  A sensor installation hole 13 is provided at a predetermined position of the side pillar 11 on the side rail fixing surface 111 side. The human sensor 2 is installed in the sensor installation hole 13 toward the opposite side pillar 11.

  Thus, since the human sensor 2 is directed to the opposite side pillar 11 (to the side pillar 11 opposite to the side pillar 11 to which the human sensor 2 is attached), The human sensor 2 detects the presence of a person by grasping the crosspiece 12. Therefore, the presence of a person can be detected more easily and reliably.

  In the present embodiment, the human sensor 2 is a pyroelectric sensor (thermal sensor) that detects heat (infrared rays) emitted from the human body. By using this pyroelectric sensor, the presence or absence of a person can be easily detected, while power consumption can be reduced and the apparatus can be installed at low cost.

  In the present embodiment, a pyroelectric sensor is used as the human sensor 2, but the present invention is not limited to this, and various suitable sensors such as an optical sensor and a microwave sensor can be used.

  Moreover, in this embodiment, although the human sensor 2 is provided in the position where each side pillar 11 faces, either one may be sufficient. When the human sensor 2 is provided at the facing position, one human sensor 2 irradiates the other human sensor 2 with infrared rays, and normally the other sensor 2 always detects infrared rays. In addition, it is good also as detecting a person's presence by a person grasping the horizontal rail 12 and interrupting | blocking the infrared irradiation from one human sensitive sensor 2. FIG.

  Moreover, in this embodiment, although the several human sensitive sensor 2 is provided also about the longitudinal direction of the side pillar 11, any one may be sufficient. Further, the position (height) can be suitably used according to the height of the sea level 200 and the situation of tide level fluctuation. For example, from the viewpoint of finding an intruder, it may be provided above the quay ladder 1, but from the viewpoint of early discovery of an intruder or discovery of a person who has accidentally dropped water, the human sensor 2 is also provided below. It may be provided at a position that is somewhat higher than the height of the sea level 200 at the time of attachment and low tide (a height at which waves do not take much). In particular, when a pyroelectric sensor is used, there is a possibility that heat (infrared rays) is not transmitted well in water and human presence cannot be detected. On the other hand, when the human sensor 2 is provided at a very high position, when the transmission device 5 transmits a detection signal, an intruder has already entered the harbor facility, or the quay ladder 1 is fully grasped. There may be a problem that a person who falls is not detected. Therefore, by providing a plurality of human sensors 2 in the longitudinal direction of the side pillars 11 as described above, the position as low as possible (close to the height of the sea surface 200), regardless of the height of the sea surface 200. It is possible to place a person in a state where the presence of a person can be detected at (position), and to detect the presence of a person earlier and more reliably.

  In the present embodiment, the human sensor 2 is provided on the quay ladder 1, but the present invention is not limited to this, and for example, the human sensor 2 may be provided for each predetermined region. In particular, this system is effective when there are a plurality of quay ladders 1 nearby, and this system can be constructed at a low cost.

  Here, the transmission device 5, the illuminance sensor 8, and the alarm device 3 will be described. The transmission device 5 of the present embodiment includes a control unit 50 that generates a detection signal in response to an electrical signal from the human sensor 2, and a transmission antenna 51 for wirelessly transmitting the detection signal, and whether or not it is nighttime. In addition to an illuminance sensor 8 that senses the above, it is incorporated in an alarm device 3 that visually alerts a person on the ground (on the ground 1002 of the quay 100) by light emission. The alarm device 3 includes a support 33 for placing the light emitting unit 31 at a predetermined height and a base 34 that supports the support 33. In the present embodiment, a solar power generation unit 32 is provided on the top of the alarm device 3, and the solar power generation unit 32 supplies power to the human sensor 2, the transmission device 5, the illuminance sensor 8, and the alarm device 3. Configured to do. In addition, about the structure of the transmission antenna 51 and the illumination intensity sensor 8, it does not specifically limit to the structure shown in figure, Various structures, such as integrating integrally in the housing | casing part of the alarm device 3, are applicable.

  The control unit 50 of the transmission device 5, the human sensor 2 and the alarm device 3 are electrically connected, and an electric signal is transmitted to the control unit 50 of the transmission device 5 when the human sensor 2 detects a person. It is done. The human sensor 2 has a different ID for each quay ladder system 10 (that is, each human sensor 2) (see FIG. 1), and the detection signal transmitted from the transmitter 5 includes the ID. Is configured to be included.

  In the present embodiment, the control unit 50 stores the ID. When receiving the electrical signal from the human sensor 2, it generates a detection signal including the ID and transmits the detection signal to the management unit 6 via the transmission antenna 51. When the management unit 6 receives the detection signal from the transmission device 5, the management unit 6 identifies the quay ladder system 10 that has transmitted the detection signal by any one or a combination of sound (alarm sound, etc.), lamp emission, or monitor display. And alarm. For example, a map of the port facility is displayed on the monitor, and the position of the quay ladder system 10 to which the detection signal is transmitted from the ID included in the detection signal is blinked on the map.

  Also, when there is no manager in the management unit 6, when the manager leaves the management unit 6, when a detection signal is received, a call is automatically made to a predetermined portable terminal 7 or an e-mail is automatically sent It can be performed. In the case of a telephone, an ID or the like included in the detection signal (such as an ID or a location or area of the quay ladder system 10 to which the ID is attached) may be notified by an artificial voice. In the case of electronic mail, an ID or the like may be described in the text.

  Thus, the human sensor 2 is provided in each of the plurality of quay ladders 1 (the quay ladder system 10), and the quay ladder 1 and the human sensor 2 are configured in a one-to-one correspondence. A different ID is assigned to each of the plurality of human sensors 2. Therefore, in the management unit 6 or the portable terminal 7, the human sensor 2 that detects the presence of a person can be easily identified, and it is easier and more directly grasp which quay ladder the intruder has used. can do.

  In the case where the human sensor 2 is provided for each predetermined area, an ID may be set for each human sensor 2. In this case, the administrator who has received the detection signal can easily grasp from which area the person has entered.

  In the present embodiment, the detection signal is transmitted from the transmission device 5 to the portable terminal 7 via the management unit 6. However, the transmission signal may be transmitted directly from the transmission device 5 to the portable terminal 7. Good.

  Further, the control unit 50 generates an alarm from the alarm device 3 in response to the electrical signal from the human sensor 2.

  Therefore, when an intruder uses the quay ladder 1 to give an alarm, the intruder is threatened, and when the administrator 70 rushes to the vicinity of the quay ladder 1 from which quay ladder 1 It can be easily visually confirmed.

  In addition, the illuminance sensor 8 and the control unit 50 of the transmission device 5 are electrically connected to allow detection by the human sensor 2 (the detection by the human sensor 2 is transmitted to the transmission device 5 and the alarm device 3. Alternatively, the activation setting for determining whether or not the human sensor 2 is supplied with electric power from the photovoltaic power generation unit 32 detects whether the illuminance sensor 8 has an illuminance of a predetermined value or more, and day or night Is transmitted to the control unit 50 of the transmission device 5.

  In this way, by performing the activation setting of the human sensor 2 by the illuminance sensor 8, normal port work is performed, and the human sensor 2 works during the daytime when the operator frequently uses the quay ladder 1. First, the presence of an intruder can be detected by detecting the presence of a person at night when the quay ladder 1 is not used. Therefore, the illuminance sensor 8 can reduce false alarms and transmit a more accurate detection signal.

  The activation setting of the human sensor 2 by the illuminance sensor 8 may be always performed, or the human sensor 2 is activated regardless of the detection of the illuminance sensor 8 (detection of the human sensor 2 in the daytime). It may be configured to be switchable to a setting of “allowed”. For example, this is effective when it is necessary to allow detection of the human sensor 2 even during the daytime when a port operation is not performed (a closed day or the like). Moreover, these setting switching may be switchable in each quay ladder system 10 or may be configured to be switchable collectively or individually in the management unit 6. Further, the activation setting of the human sensor 2 may be set by the control unit 50 and / or the alarm device 3 of the transmission device 5. The configuration of the switching itself may be mechanical (such as a switch) or may be software.

  The human sensor 2 is wired from the photovoltaic power generation unit 32, the transmission device 5, and the alarm device 3 to the quay ladder 1 through the light emitting device 3 and the support 33, and the side pillar 11 of the quay ladder 1. The human sensor 2 is wired through the cavity 14 (indicated by the wiring 16 in FIG. 1). In addition, by wiring inside or on the back of the horizontal rail 12, wiring can be simply made to the human sensor 2 arranged on the opposite side column. A wiring cover 17 is provided for the wiring on the ground between the alarm device 3 and the human sensor 2, and the wiring in the cavity 14 of the side pillar 11 and in / in the side rail 12 is waterproofed (waterproof pipe). Etc.) is performed.

  In this way, the electric power of the human sensor 2, the transmission device 5, the illuminance sensor 8, and the alarm device 3 is supplied by the solar power generation unit 32. Therefore, the quay ladder system 10 can be independently installed at a predetermined location without connecting a power source.

  Here, the aspect of the light emitting unit 31 of the alarm device 3 will be described. FIG. 5 is a diagram showing a specific example of a stand-type alarm device used in the quay ladder system of FIG. FIG. 6 is a diagram showing a specific example of a ground-mounted alarm device used in the quay ladder system of FIG. In FIGS. 5 and 6, the transmission antenna 51 and the illuminance sensor 8 are not shown.

  The alarm device 3 in FIG. 5A is arranged so that the LED 35 is arranged in the circumferential direction of the internal cylindrical structure as a light emitting unit, and flashes and emits light at different timings, thereby making it appear as if it was simulated rotational light emission. . In this way, since it looks as if it is rotating and emitting light only in the light emitting mode, a highly visible light emitting portion can be realized at low cost. Furthermore, the visibility can be further improved by arranging the multi-stage LEDs 35 in the vertical direction. Note that it is naturally possible to implement a mode in which the LED 35 is provided with a rotation mechanism that can rotate horizontally, and the LED 35 is actually lit while being constantly lit.

  In the alarm device 3 of FIG. 5B, a plurality of LEDs 35 are similarly arranged on the side surface of the rectangular parallelepiped as a light emitting unit. Since the alarm device 3 is also provided with the photovoltaic power generation unit 32 on the side surface, the light emission luminance of the LED 35 and / or the sensor sensitivity of the human sensor 2 is further increased (the LED 35 having a higher light emission luminance and / or a person having higher sensitivity). The sensor 2 can be arranged).

  The alarm device 3 of FIGS. 6A and 6B is a ground-installed alarm device that does not require the support 33 (the base 34, the light emitting unit 31, and the solar power generation unit 32 are substantially integrally formed). 3. Since it is directly attached to the ground 1002 of the quay 100, it is inferior to the stand-type alarm device 3 in terms of visibility, but is excellent in terms of cost and durability. Therefore, the alarm device of the stand-type alarm device 3 is appropriately selected. It is preferable to add to the auxiliary. Or, a voice alarm device (speaker device, etc.) is provided separately to notify the alarm to people who are far away, but applicable to those who have noticed the alarm sound and approached the quay 100 (rescuers) It is good also as showing the position of the ladder for quay to indicate with the alarm device 3 as shown in FIG. The alarm device 3 in FIG. 6A includes a light emitting unit 31 in which LEDs (not shown) are arranged in parallel in the front-rear direction, while the alarm device 3 in FIG. 6B includes LEDs (not shown). ) Radially arranged in the circumferential direction (the above-described pseudo light emission mode can also be adopted). Of course, it is also possible to use a voice alarm device in combination with the alarm device 3 of FIGS.

  As described above, it is possible to perform more effective alarm notification by arranging the alarm devices 3 of a plurality of modes in an appropriate combination.
