Description

  The present invention illuminates and / or within underground passages (in this specification, the term “underground passage” is used in a broad concept including passages that require illumination in addition to so-called underground passages). It relates to underground passage facilities that monitor abnormalities and issue warnings as necessary.

  There are many underground passages mainly in urban areas. For example, there is a broad underground passage as defined above for traversing a road with a large road width, under a track, or on a track.

  In such underground passages, in most cases, lighting is performed continuously for 24 hours, and in the case of a long passage, the accumulated energy consumed for the lighting is enormous. The neglect of such a situation cannot be overlooked in the recent global situation of reducing carbon dioxide emissions on a global scale, and the use of wasted energy can be improved as much as possible. Needless to say, it is desirable.

  In view of such a situation, the present inventor has recently proposed a new and useful tunnel lighting facility that is controlled so that only lighting fixtures are turned on only when necessary, and are turned off when unnecessary (in this specification, the prior application is applied). (Referred to as Patent Document 1).

In recent years, the level of security in Japan has also declined, and passers-by, mainly women who are trying to pass, were attacked by thugs in the late-night hours when there were almost no passers-by in the underground passage as described above. Or, a situation where money is robbed is happening like a daily event. Under such circumstances, the safety of passers-by in underground passages should be guaranteed as soon as possible, even at midnight.
In addition, as a security monitoring and security maintenance apparatus in a general house, it has already been proposed (see Patent Document 2).
JP2003-217873A. Unexamined-Japanese-Patent No. 2002-230655.

  The present invention has been made in view of the current situation as described above, and provides an underground facility that performs illumination without waste with respect to the illumination of the underground passage, and monitors the abnormality of the underground passage as necessary. The purpose is to provide underground passage facilities that can issue warnings.

The underground passage facility according to the present invention is an underground passage facility configured to illuminate the passage with an illumination lamp and monitor an abnormality in the passage.
This underground passage facility is provided as an illumination lamp that can change the illuminance provided as the illumination lamp, an illuminance switching means that can change the illuminance, and an abnormality detection means that detects an abnormality in the passage . An ITV camera and a sound collecting microphone , a speaker that amplifies the sound obtained from the sound collecting microphone as an alarming means for alarming an abnormality in the passage, and an entry detecting means for detecting an intruder's entry into the underground passage, A shutter provided as a security maintenance means provided at the entrance of the underground passage and closing the underground passage from the outside; and a control device for controlling the illuminance switching means and operating the warning means and the security maintenance means ,
When the control device obtains a signal from the entry detecting means that the entry of a passerby into the underground passage has been detected, the control device issues a signal for increasing the illuminance to the illuminance switching means, thereby reducing the illuminance of the illumination lamp. While controlling to raise,
When an abnormality from the abnormality detecting means is detected , the sound of the sound collecting microphone is enlarged and flowed through the speaker, and the state in the underground passage is photographed and recorded by the ITV camera, and The shutter is controlled to be closed .

In such a case, the configuration is excellent in that the signal line installation work becomes easier.

  And according to the underground passage installation concerning this invention comprised in this way, it can act as follows. Hereinafter, the control content of the control device Cn will be described along with the flowchart of FIG. 3 together with the operation of the underground passage facility.

  First, the lighting will be described. As shown in the flowchart of FIG. 3, in step 1 (S1), the presence sensor 1 detects whether there is a passerby, and the presence sensor 1 detects the passerby. When not, it transfers to step 2 (S2) and the said control apparatus Cn lights the said illumination lamp 2 with the illumination capability of 10%. And it returns to step 1 (S1).

  On the other hand, when the human sensor 1 detects a passerby, a signal to that effect is transmitted from the human sensor 1 to the control device Cn, and the process proceeds to step 3 (S3). The illumination lamp 2 of the block (for example, the first block Br1) in which the human sensor 1 is disposed is turned on with 100% illumination capability.

  Hereinafter, in FIG. 1, a passerby enters the underground passage facility from the entrance En1 and then passes through the fifth block Br5, passes through the fourth block Br4 and the eighth block Br8, and then passes through the third block. An example of the case of going out of the underground passage facility from the Br3 entrance En5 will be described.

  When a passerby enters the underground passage facility from the entrance En1, the human sensor 1 disposed at the entrance En1 transmits a signal indicating that the passer is about to enter the control device Cn. As a result, the control device Cn turns on the illumination lamp 2 of the first block Br1 with 100% illumination capability (step 3 (see S3)).

Next, in step 4 (S4), the ITV camera 4 detects in which direction the passer-by travels.
In FIG. 1, if a passerby travels from the first block Br1 toward the entrance En7, in step 5 (S5), the ITV camera 4 (and / or) arranged in the fifth block Br5. The ITV camera 4) arranged in the sixth block Br6 transmits an image signal to that effect to the control device Cn. As a result, the control device Cn determines that the passerby proceeds toward the fifth block Br5, and turns on the illumination lamp 2 of the fifth block with 100% illumination capability. At this time, the illumination lamp 2 of the first block Br1 is still lit with 100% illumination capability.

  Next, in step 6 (S6), when the passerby approaches the fourth block Br4 side in the fifth block Br5, the ITV camera 4 of the fifth block Br5 or the fourth block Br4 displays that image. The signal is transmitted to the control device Cn. As a result, the control device Cn determines that the passerby proceeds to the fourth block Br4 side, and turns on the illumination lamp 2 of the fourth block Br4 with 100% illumination capability. At this time, the control device Cn reduces the illumination lamp 2 of the first block Br1 to 10% of the illumination capability.

  Then, in step 7 (S7), in FIG. 1, when the passerby passes from the fifth block Br5 to the eighth block Br8 side through the fourth block Br4, the fifth block Br5, the fourth block The ITV camera 4 of Br4 or the eighth block Br8 transmits an image signal to that effect to the control device Cn. As a result, the control device Cn determines that the passerby travels to the eighth block Br4 side, and turns on the illumination lamp 2 of the eighth block Br4 with 100% illumination capability. At this time, the control device Cn reduces the illuminating lamp 2 of the fifth block Br5 to a lighting capacity of 10%.

  Next, in step 8 (S8), when the passerby approaches the third block Br3 side in the eighth block Br8, the ITV camera 4 of the eighth block Br8 or the third block Br3 indicates that. The image signal is transmitted to the control device Cn. As a result, the control device Cn determines that the passerby proceeds to the third block Br3 side, and turns on the illumination lamp 2 of the third block Br3 with 100% illumination capability. At this time, the control device Cn reduces the illumination lamp 2 of the fourth block Br4 to 10% of the illumination capability.

  Next, in step 9 (S9), when the passerby approaches the entrance En5 in the third block Br3, the ITV camera 4 of the third block Br3 places an image signal to that effect or in the entrance En5. A detection signal from the human sensor 1 is transmitted to the control device Cn, and the control device Cn checks whether or not a passerby is detected.

  As a result, when a passerby is detected, the illumination state is maintained as it is.

  On the other hand, in step 9 (S9), if the ITV camera 4 of the third block Br3 detects an image signal to that effect or if the human sensor 1 disposed at the entrance / exit En5 does not detect a passerby, step 10 (S10) ), The control device Cn determines that the passerby has exited the underground passage facility from the entrance En5, and reduces the illumination lamp 2 of the eighth block Br8 and the third block Br3 to a lighting capacity of 10%. Let

Thus, according to the underground passage facility according to the present embodiment, the control device Cn has a lighting capacity of 100% only for the lamps 2 in the area (passing block and blocks adjacent thereto) necessary for passers-by. The other lamps 2 are lit only with a lighting capacity of 10%.
Therefore, according to the underground passage facility according to the present embodiment, it is possible to contribute to energy saving as a result of extremely rational illumination of lighting only a necessary and sufficient area. In particular, at midnight, few people pass through the underground passage Tn, so the power saving effect in these time zones is great.

  Next, this underground passage facility abnormality monitoring and alarm function will be described with reference to the flowchart, taking as an example a case where a passerby is attacked by a thief in the fifth block Br5.

  In the state where the passer-by is passing the fifth block Br5, in step 1 (S1), the state of the passer-by at that time is the fifth block Br5, the fourth block Br4 or the fourth block Br4 as described above. The ITV camera 4 arranged in the first block Br1 is transmitted to the image sensor sensing block Br22 in the control device Cn, and from this image, the control device Cn checks whether an abnormal situation has occurred. At this time, a sound signal from the sound collecting microphone 4A is also checked by the control device Cn whether or not a passerby screamed. If there is no signal for judging an abnormal situation, the check is continued as it is.

On the other hand, when the control device Cn determines from the signals from the ITV camera 4 and the sound collecting microphone 4A that the passerby has been attacked by a thief (occurrence of an abnormal situation) in the fifth block Br5, the process proceeds to step 2 (S2). Transition. The determination of the abnormal situation from the voice is configured such that, for example, when a specific sound range (or volume) such as a scream is detected, the control device Cn determines that the abnormal situation is present.
In this step 2 (S2), when an abnormal situation occurs, the control device Cn detects the abnormal situation from the image processing and sound, and sends the sound from the sound collecting microphone 4A through the amplifier 28 into and out of the underground passage facility. Enlarged flow through the speaker Am provided. Therefore, if there are other passersby in the underground passage Tn, or if there are people passing outside the underground passage facility or nearby people, it will be possible to hear this abnormal situation and go to rescue quickly. it can.
Further, such an abnormal situation is displayed on a monitor TV provided in a management station (and / or police station) of an underground passage facility via the ADSL converter 23, a communication line, and the ADSL demodulator 52. Abnormal sound is transmitted. When an administrator (or police officer) knows such an abnormal situation, a warning can be issued from the remote microphone 54 to the perpetrator via the speaker Am.
Further, in the case of this underground passage facility, when the control device Cn determines that the abnormal situation is present, the illumination lamps 2 of all the underground passage facilities are turned on, and visually, passersby inside and outside the underground passage facility are visually informed. Inform the inside of the abnormality.
When the control device Cn determines that the abnormal situation has occurred, the camera tracks the passerby and its vicinity so as to zoom in on the ITV camera 4 capturing the situation so that details can be clearly seen. In order to make it easier for the manager (or police officer) to grasp the situation, the storage device 21 records all the situation. This record is controlled so that it remains as it is until it is intentionally deleted by an administrator or the like.
Further, when the control device Cn determines that an abnormal situation has occurred, the control device Cn closes the shutters St disposed at the entrances En1 to En8 so that the perpetrator cannot go out of the underground passage facility.

By the way, even when the victim presses the emergency button 6, a signal to that effect is transmitted to the control device Cn, and the control device Cn determines that an abnormal situation has occurred and performs the control as described above. To implement.
Therefore, when the emergency button 6 is arranged in this way, even when the ITV camera 4 or the like cannot grasp the abnormal situation, it is possible to grasp the abnormal situation easily and accurately.

  By the way, in the said Example, although the thing which can be switched to 100% capacity | capacitance and 10% capacity | capacitance was demonstrated about the illumination light, even in the case of 100% capacity | capacitance and 5% capacity | capacitance, or other ratios It may be possible to reduce the required power.

  In addition, the abnormal situation has been described in the case of being attacked by a thief, but in the case where a sick person or an elderly person falls on the passage, etc. On the other hand, it is possible to promptly notify the manager, police station, fire department, etc.

  As an alarm device, it is also effective to arrange an alarm lamp in addition to the speaker. In addition, the control device is configured to transmit the occurrence of the abnormal situation, the location of the underground passage facility, the voice of a passerby (victim), and the like by radio of an emergency frequency used by the police or the fire department. This is also a preferred embodiment.
