Description

Technical Field

[0001] The present invention relates to a security system, and more particularly to a security system that detects the intrusion of a person or an animal into a security area and captures or deters them.

Background Art

[0002] In recent years, thefts such as theft of solar panels, theft of crops in fields, theft of electric wires, and theft of manhole covers have been occurring continuously, and devices for deterring theft have been proposed. For example, Patent Document 1 describes a thief catcher that is provided with a storage unit for storing a capture net in a reduced state on the ceiling or the like at important locations inside a building. In this thief catcher, an opening / closing part is provided in the storage unit, and when a sensor or the like senses that a thief has entered the lower part of the storage unit, the opening / closing part automatically opens, or a security guard or the like confirms it with a television camera or the like and manually opens it by operating a switch. When a thief A enters the lower part of the storage unit, the opening / closing part opens, the capture net pops out and expands, and at the same time as the capture net covers the thief, the lower opening part performs a closing operation and is provided so as to wrap the thief.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the thief catcher described in Patent Document 1 senses a thief with a single sensor, it is conceivable that the thief may not be detected due to a malfunction or change over time of this sensor, resulting in false detection. In particular, it may not be maintained for a long time and may be used as it was installed initially, and sensitivity abnormalities due to deterioration or change over time of the sensor are likely to occur. In this case, although the thief catcher is installed, it does not operate when it is most needed, and the damage caused by thieves cannot be reduced.

[0005] In addition, this thief catcher is configured to be manually opened by a security guard or the like through confirmation with a TV camera or the like and a switch operation. Also in this case, there are problems due to deterioration of the sensor and changes over time, and the operating costs due to labor costs of security guards or the like are high, so it cannot be adopted at all in private homes.

[0006] In addition, the conventional system lacks functions for actively capturing intruders or preventing intrusion acts beforehand, and the response after intrusion is limited. Also, although advanced detection technologies using wire break detection sensors and cameras have been proposed, there are few systems that combine a plurality of different detection principles, and the response to intrusion patterns is insufficient. Furthermore, there are systems equipped with a net injection device and a deterrence device as security devices, but configurations for integrating these and operating them efficiently have not been sufficiently studied.

[0007] In order to solve the above problems, an object of the present invention is to provide a security system that includes a plurality of sensors having different detection principles, reliably detects intruders, and effectively performs operations for capturing or deterring them. In particular, a system that can detect intrusion acts such as prying open a window and can quickly respond by utilizing a net injection device or a deterrence device is realized.

Means for Solving the Problems

[0008] The security system according to the present invention includes a sensor unit capable of detecting that a person or animal as a detection target has entered a security area, and a security device that performs an operation of capturing the detection target or deterring the detection target based on the detection result of the sensor unit. The sensor unit can include a plurality of sensors having different detection principles from each other.

[0009] The sensor unit includes at least one selected from a window sensor capable of detecting opening and closing of a window, a biometric sensor capable of detecting the body temperature or movement of a person or animal, a camera sensor capable of identifying the detection target using artificial intelligence based on imaging data of a camera, or a wire break detection sensor capable of detecting wire breakage.

[0010] The net injection device is configured to be able to inject the net by using any one of a spring, compressed air, or combustion gas.

[0011] Furthermore, the security device can be provided on the inner or outer ceiling of openings such as entrances and exits or windows in the security area. Also, when the security area is outdoors such as a farmland or a solar power generation facility and there are no windows or entrances, it can be attached to a pole erected in the security area or a string-like member connected to the pole.

[0012] Moreover, a battery for storing the power generated by the solar cell may be provided, and all or part of the system operates by the power from the battery.

[0013] Furthermore, an imaging device capable of imaging a detection target and a transmission device for transmitting predetermined information to a predetermined destination based on the detection result of the sensor unit can be provided.

[0014] In addition, any combination of the above components or components and expressions of the present invention that are mutually replaced between devices, systems, etc. are also effective as aspects of the present invention.

Advantages of the Invention

[0015] According to the present invention, since the security device is provided above the intruder, it is possible to surely prevent intrusion without being noticed by intruders who tend to concentrate on the feet and hands. Also, by combining a plurality of sensors having different detection principles, various intrusion patterns such as window prying, wire cutting, and intruder movement can be detected with high accuracy. In addition, the net injection device and the deterrence device quickly perform operations to capture or deter intruders, improving the security effect. Furthermore, by providing a solar cell and a transmission device, power supply independence and remote monitoring are possible, enhancing the practicality in houses and commercial facilities. Also, according to the present invention, it is possible to provide a security system capable of reducing the influence of sensor deterioration and changes over time.

Mode for Carrying Out the Invention

[0017] [Example 1] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. This embodiment is applicable to security for houses, commercial facilities, warehouses, etc., and is particularly effective for preventing intrusion into windows and entrances. It can be used in a wide range of applications due to its simple installation and high detection accuracy. In addition, this embodiment is also applicable to security for agricultural facilities such as fields and houses, and energy systems such as solar power generation systems.

[0018] FIG. 1 shows the overall configuration of the security system according to the present invention. The security system 100 includes a sensor unit 10, a security device 20, a control unit 30, a battery 40, an imaging device 50, and a transmission device 60. The sensor unit 10 includes a window sensor 11, a biometric detection sensor 12, a camera sensor 13, and a wire break detection sensor 14. The security device 20 includes a net injection device 21, a suppression device 22, and a marking device 23.

[0019] (Configuration of Sensor Unit) The window sensor can be anything as long as it can detect the opening and closing of the window, and various sensors based on known principles can be adopted. In this example, as shown in FIG. 2, the window sensor 11 arranges a magnet 112 and a reed switch 114 on the frame F and the sash S of the window W, respectively, to detect the opening and closing of the window W, that is, the opening and closing of the sash S.

[0020] The biometric sensor can be anything as long as it can detect the body temperature or movement of a human or animal, and various sensors based on known principles can be adopted. In this example, the biometric sensor 12 is a passive infrared (PIR) sensor, which detects the body temperature and movement of a human or animal within the security area near the window.

[0021] The camera sensor can be anything as long as it can identify the detection target, and various sensors based on known principles can be adopted. In this example, the camera sensor 13 is equipped with a CCD camera and an image processing unit, and uses artificial intelligence to identify the detection target based on the captured image data.

[0022] The wire break detection sensor can be anything as long as it can detect the breakage of the wire installed in the security area, and various sensors based on known principles can be adopted. In this example, the wire break detection sensor 14 passes a weak current through the conductive wire arranged along the window frame and detects the opening of the circuit due to the wire break. The wire break detection sensor 14 can be arranged not only on the window frame but also at various locations within the security area.

[0023] (Configuration of the security device) The net ejection device can be anything as long as it can eject a net capable of capturing the detection target, and various mechanisms based on known principles can be adopted. In this example, as shown in FIG. 3, the net ejection device 21 includes a housing 21a for storing the net N, a combustion gas generation unit 21b for ejecting the net, and a trigger mechanism 21c. The combustion gas generation unit 21b ignites the gunpowder to generate combustion gas. The combustion gas G applies a thrust to the weight M provided at the tip of the net N, and the net N can be ejected from the ejection port 21d within a range of 5 to 10 m.

[0024] The deterrent device can be anything as long as it can deter the intrusion of the detection target, and various mechanisms based on known principles can be adopted. This deterrence includes those by "intimidation". In this example, the deterrent device 22 is equipped with a high-pitched buzzer and an LED strobe light, and deter the detection target with sound and light.

[0025] The marking device can be anything as long as it can spray a colored ejecta, and various mechanisms based on known principles can be adopted. In this example, the marking device 23 sprays a colored liquid (e.g., fluorescent paint) or powder with compressed air to mark the object to be detected. For example, it may be configured to eject a ball-shaped container (e.g., a color ball) containing a colored ejecta toward the object to be detected. Further, the marking device may be combined with a net ejection device, and may be configured such that a color ball or the like is ejected together with the net.

[0026] (Operation of the system) The control unit 30 receives the detection signal from the sensor unit 10 and outputs a control signal for controlling the operation of the security device 20. For example, when the window sensor 11 detects that the window W has been pried open, the control unit 30 activates the net ejection device 21 to capture the intruder with the net N. At the same time, the deterrent device 22 activates the buzzer and the light, and the transmission device 60 transmits the alarm information to the security company.

[0027] (Installation configuration) The sensor unit 10 and the security device 20 are attached to the pole P within the security area. A string-like member H (e.g., a wire rope) is connected to the pole P, and the sensor and the device can be suspended and arranged. Thereby, the periphery of the window and the entrance can be effectively monitored. Further, when the security area is relatively large such as a field, a plurality of poles may be erected at intervals. It is possible to attach a plurality of sensors and devices to each pole or to the string-like member stretched between a plurality of poles.

[0028] (Power supply) There is no limitation on the power supply form, and it may be supplied from a so-called commercial power supply. In this example, power is supplied from a battery that stores the power generated by the solar cell. The battery 40 is charged by the solar cell panel and supplies the power required for the operation of the system. Thereby, the system operates even during a power outage, and independence is ensured. Note that this battery may also be rechargeable from a commercial power supply.

[0029] (Imaging and transmission) There is no limitation to the imaging device. The imaging device 50 in this example is a camera that captures an intruder and transmits video data to the control unit 30. It may simply record the video data. The transmission device 60 transmits detection information and video data to a predetermined destination (e.g., the user's smartphone, a security company) via wireless communication (e.g., Wi-Fi, 4G, 5G).

[0030] (Pole and string-like member) FIG. 4 shows an installation example of the pole and the string-like member. In this example, the pole P is erected near the outer edge of the security area. The string-like member H is stretched between the pole P and the eaves of the building. The window sensor 11 is provided on the window W of the building. The biometric detection sensor 12 is provided above a predetermined detection area in the string-like member H. The camera sensor 13 is provided, for example, on the pole P to detect a detection target in a predetermined detection area. The wire break detection sensor 14 is provided, for example, on a fence to detect a detection target that breaks through the fence without passing through the gate. The net ejection device 21, the suppression device 22, and the marking device 23 are provided above a predetermined detection area. Each element is connected as shown in the block diagram of FIG. 1.

[0031] [Embodiment 2] In Embodiment 2, a configuration is adopted in which the net ejection device 21 ejects a net using compressed air. This avoids the regulations associated with the use of gunpowder and facilitates installation at home. Other configurations are the same as those in Embodiment 1.

[0032] (Features of the embodiment) This security system reliably detects forced entry into a window by a window sensor or a wire break detection sensor, and captures or suppresses an intruder with a net ejection device or a suppression device. By combining sensors with different detection principles, false detections are reduced and various intrusion patterns can be accommodated. In addition, self-sufficient power supply and remote monitoring are realized by a solar cell and a transmission device, making it highly practical.
