Description

  The present invention relates to a monitoring device including a monitoring camera and an infrared sensor, and a monitoring system using the monitoring device.

  In recent years, with the advancement of digital technology, video systems such as cameras have become highly functional, miniaturized, and low in price, and are often used as surveillance cameras. In addition, it is widespread to use a surveillance camera to monitor a room or a specific area and acquire image information for crime prevention or criminal tracking.

  Surveillance devices with security cameras that are used outdoors often have a security camera attached to the top of buildings, telephone poles, street lights, etc., and the distance from which the focus of the camera device fits the purpose from near. Get image information until.

  On the other hand, the area to be monitored is diversified, and even if it is called “outdoor”, it is frequently used for monitoring devices such as roads, house premises, construction sites, construction sites, and yards for storing used cars. Demands and conditions are required. For example, for a construction site or a construction site, from the viewpoint of safety management or security, the construction site is surrounded by a steel plate or the like to secure a construction area, and construction is performed using materials or heavy machinery in the area.

  Construction may be performed day or night, but there are also civil engineering construction sites where construction is performed only during the day and not during the night. In such a field, it is necessary to prevent theft of heavy machinery and materials at night. In order to prevent theft and to secure security, for example, it is possible to secure specialized security guards, but it is necessary to carry out safety and hygiene management, labor costs etc. It is not efficient in terms of preparing for the rare case of time.

  For this reason, crime prevention and security management have become the mainstream for construction sites and the like by installing monitoring devices that do not cost anything other than maintenance. A system for monitoring a construction site by such a flow has been proposed so far. For example, Japanese Unexamined Patent Application Publication No. 2009-282754 (Patent Document 1) proposes a system that performs infrared detection between an infrared sensor and an infrared generator in order to monitor a region such as a construction site. This system uses a plurality of infrared sensors and a light source that generates infrared rays in a monitoring area, and when an intruder or the like cuts off infrared rays, the infrared sensor detects this and performs an alarm or notification.

  Even with this system, it is possible to detect intrusions within the monitoring area. However, there is a possibility of malfunction due to, for example, invasion of birds or small animals, or sensor contamination. In addition, a light source for generating infrared light is required to have a higher power as the area becomes wider, and the light source cost and the electric charge are increased, so that it is not always an efficient system.

  In addition, since the locations of construction and construction sites change one after another and the arrangement of materials and heavy machinery on the site changes every moment, the monitoring on the optical axis established between the light source and the sensor is not appropriate. In addition, for example, unlike an environment such as a fixed area such as a material storage area or a heavy equipment storage area, it is necessary to effectively use the monitoring device used in the previous site even if the construction site changes.

  Hereinafter, the present invention will be described with embodiments, but the present invention is not limited to the embodiments described below. FIG. 1 is a schematic diagram of a monitoring system 100 in which the monitoring device of this embodiment is installed. The monitoring system 100 includes a monitoring area 120 defined by a wall 102 constructed of a steel plate or the like, and a plurality of monitoring devices 104 installed adjacent to the wall 102. In the monitoring area, construction work and civil engineering work are performed, and materials and heavy machinery corresponding to this are arranged vertically and horizontally. In the illustrated embodiment, a door 110 is provided on the wall 102 for crime prevention such as at night. Note that the door 110 is not necessarily provided.

  The monitoring device 104 includes a support column configured by connecting a plurality of segments, a monitoring camera (not shown) attached in the vicinity of the top portion 106, and the like. Further, the base portion 108 of the support column is configured to be embedded as a root segment, and is embedded to a predetermined depth on the ground of the monitoring area 120. It is set as the structure which can remove a support | pillar.

  FIG. 2 is a diagram illustrating a detailed configuration of the monitoring device 104 according to the present embodiment and an installation state with respect to the wall 102. The monitoring device 104 includes a support column 202 having a predetermined length by connecting a plurality of segments with bolts and nuts, and one end of the support device is embedded at a predetermined depth from the ground 200. It is supposed to be self-supporting. The wall 102 is held by supports 206, 208, 210 such as steel pipes, and firmly fixes the wall 102. The monitoring device 104 is installed at a position adjacent to the wall, and detects intrusion within a predetermined distance range of the monitoring area 120 from the wall.

  More specifically, the monitoring device 104 throws a warning sound from the top to the intruder, a photoacoustic generating member 104a, which is a warning generating means for generating photoacoustics, a monitoring camera 104b capable of photographing all around, and an intruder. Speaker 104c. The photoacoustic generating member 104a is provided for notifying the outside of the area that the intruder exists in the monitoring area 120 and for giving a feeling of psychological pressure to the intruder. Further, the surveillance camera 104b capable of photographing all around is capable of photographing a range of 128 ° in the horizontal 360 ° vertical direction, and has a zoom function in order to record intruder image information with high accuracy. Is preferred. The speaker 104c also functions as an alarm generating means, and is preferably mounted to psychologically intimidate by throwing an audio alarm instead of an alarm sound to an intruder at a remote location. The detailed standard / performance of the monitoring camera 104b can be selected as appropriate so as to achieve a specific purpose.

  Further, the monitoring device 104 is provided with a red rotating lamp 104d for notifying that the monitoring device 104 is in operation, and further, an omnidirectional triple sensor infrared sensor 104e and a control device 104f are attached. Yes. The infrared sensor 104e, which will be described in detail later, has two sensors that detect infrared rays from the horizontal direction, and one sensor detects infrared rays from the ground side, and has a long shape feature in the vertical direction. It is possible to detect selectively. In addition, the control device 104f controls each functional unit, and when an intrusion is detected, for example, notifies the administrator such as a contractor as the Internet, e-mail, or image information, and notifies the police or the like A microcomputer, a memory, a modem, a network board, and the like are housed, and external reporting is possible via the communication line 214 and the like. In the present embodiment, as the alarm activation means such as the infrared sensor 104e, any means known so far can be used according to the application and installation location, such as an acoustic sensor, a push-type switch (button), and the like. .

  The root segment 204 of the monitoring device 104 is embedded so as to be movable to an appropriate depth in the ground. Further, a segment connecting portion (indicated by a line crossing the support column) is provided at a position protruding from the base segment 204 to the ground side, and a segment connecting portion is further provided thereon. The monitoring device 104 is installed by first burying the root segment 204 in the ground, extending the intermediate segment using fastening means such as bolts and nuts, and further connecting the top segment, so Establish the height of. Note that the total length required for the monitoring region 120 can be adjusted as appropriate by appropriately selecting the length of the segment.

  The detection method of the infrared sensor 104e of this embodiment is demonstrated using FIG. FIG. 3 is a conceptual diagram showing a detection mechanism of the monitoring device 104 of this embodiment. As shown in FIG. 3, the infrared sensor 104e includes two sensors (hereinafter referred to as A sensor and B sensor from the top) that detect horizontal infrared rays at predetermined intervals, and an intermediate between the A sensor and the B sensor. A total of three sensors are provided which are arranged and detect infrared rays from the ground direction (hereinafter referred to as C sensors).

  As shown in FIG. 3, when an intruder 302 enters the monitoring distance D formed by the infrared sensor 104 e, horizontal infrared rays 304 and 306 are detected by the sensors A and B. On the other hand, the sensor C detects infrared rays from the ground method and detects infrared rays from the vicinity of the intruder's feet. The detection results of the A sensor and the B sensor are logically summed or logically ANDed, and this result is further logically ANDed with the detection result of the sensor C, thereby generating a detection result. For this reason, as shown in FIG. 3, intrusion detection can be performed corresponding to the shape of the intruder. In addition, it is possible to reduce the possibility of false detection such as insects, sensor dirt, bird intrusions, and tree shaking.

  In addition, as shown in FIG. 3, in the present embodiment, since it does not detect crossing between the infrared sensor and the infrared light source, it is not necessary to consider the arrangement of materials and heavy equipment in the monitoring area. By performing intrusion detection from the wall 102 to the monitoring distance D, highly accurate and flexible monitoring is possible. Upon detecting the intrusion, the monitoring device 104 activates the photoacoustic generating member 104a to threaten the intruder with light and siren sound, and captures the intruder image information by photographing the intruder with the monitoring camera 104b.

  Further, when necessary, an intrusion is monitored and an intrusion repulse without delay is possible by performing an audio warning from the speaker 104c and an external report using the Internet, a telephone line, or the like. In addition, although the distance of D can be suitably selected according to the detection distance of an infrared sensor, etc., it can usually be set as the range of several m-several 10 m.

  FIG. 4 is a diagram illustrating the detection function of the infrared sensor 104e of this embodiment in more detail. It is assumed that the intrusion has moved and reached the position 402 from the position 401. At position 401, sensor C fails to detect and cannot be detected, but since infrared sensor 104e detects all directions, sensor C succeeds in detecting an intruder at position 402. At this time, since it indicates that all of the sensor A, the sensor B, and the sensor C are detected, the intrusion is detected and various alarms / notifications are performed. In other embodiments, the intruder can be determined from the detection of the dynamic position by reflecting the movement pattern and speed.

  On the other hand, a case where a dog or the like enters the monitoring area will be described. In the case of a dog, only the sensor C can detect the height, and neither the sensor A nor the sensor B can detect. As a result, the logical product of the detection results of the sensors A and B does not generate a signal for detecting the detection, and even if the logical product with the result of the sensor C is performed, a value indicating the detection is not generated. As a result, not only dogs but also false detections caused by birds, insects, dead leaves and garbage, or tree shaking can be significantly reduced. In addition, since it is not necessary to install infrared light emitting means, it is possible to reduce running costs such as electricity charges.

  FIG. 5 shows an embodiment of a monitoring zone formed by this embodiment. In the present embodiment, a plurality of monitoring devices 104 are provided along the wall 102. Each monitoring device 104 forms an anti-conical monitoring region with the infrared sensor 104e as a vertex. The monitoring devices 104 are arranged at intervals at which the conical bottom surfaces 502 in the adjacent directions overlap. As a result, no monitoring omission occurs between the monitoring devices 104 at all. Further, from the wall 102, all the monitoring devices 104 set the effective monitoring distance up to the monitoring distance D. As a result, a monitoring zone 510 having a shape along the wall 102 is formed.

  Since many intrusions are made through the wall 102, the monitoring system 100 of the present embodiment can effectively perform intrusion monitoring. At this time, it does not require complicated adjustments such as the arrangement of materials and heavy equipment in the monitoring area and the resetting of the optical axis in the prior art, and since no infrared light emitting means is used, the power consumption can be reduced, and Intrusion monitoring can be performed at low cost.

  Furthermore, since the monitoring device 104 is formed by extending a plurality of segments, and the root segment is embedded in the ground so that it can be transferred, it is removed by the user or the installer after the use at the construction site is finished. Thereafter, the user or installer can be moved to an arbitrary monitoring area, and flexible intrusion monitoring is possible. In other embodiments, the monitoring devices can be installed side by side along the edge of the street. In this case, by using the focusing range of the surveillance camera, the monitoring device has a certain width on the side where people on the street pass. A monitoring zone can be formed.
