TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security device for preventing intrusion and theft by a suspicious person. In particular, the present invention relates to a crime prevention device that detects a suspicious person direction by a suspicious person direction detection device, discharges water in that direction, and makes the suspicious person wet, thereby suppressing intrusion and theft.
[0002]
[Prior art]
Conventionally, security devices for preventing theft of vending machines and the like have been devised. For example, there is a security device disclosed in JP-A-5-334540. This security device is shown in FIG. This security device includes a vibration detecting device 1 and an inference unit 5, and distinguishes natural vibrations such as earthquakes and abnormal vibrations caused by theft by the inference unit 5 to prevent malfunction. For example, the inference unit 5 infers vibration such as an earthquake or abnormal vibration such as theft from characteristics such as the magnitude and time change of the detection signal from the vibration detection device 1. As a result, natural vibration or inadvertent vibration and abnormal vibration such as theft are distinguished to prevent malfunction. Then, when abnormal vibration is detected, an alarm is determined by the alarm determining means 6, and water is discharged from, for example, the water discharging device 7. Alternatively, the alarm stored in the alarm signal memory 9 is output from the speaker 8 by voice.
[0003]
Theft includes destruction by firearms using a burner or the like. For this reason, the security device also includes a temperature rise detection unit 2. The inference unit 5 infers the use of the burner from the temperature detected by the temperature rise detection unit 2 and the temporal characteristics of the temperature rise. This enables detection of vandalism by firearms. Then, similarly, based on the inference result of the inference unit 5, the alarm determination means 6 activates, for example, the water discharge device 7 to discharge water, thereby making it difficult to steal.
[0004]
[Problems to be solved by the invention]
However, the conventional water discharge device of the security device is excellent in inference, but ultimately simply discharges water without detecting the direction of the suspicious individual. Therefore, there is no guarantee that a suspicious person will be flooded. Further, even if it is flooded, there is a high possibility that the amount of flooding is small, and it is difficult to identify a suspicious person after the fact.
[0005]
The present invention has been made to solve the above-described problems, and its purpose is to detect a suspicious person direction by a suspicious person direction detection device when a suspicious person enters, and discharge water in that direction. This is to ensure that the suspicious person is flooded. Thereby, intrusion of a suspicious person is to be suppressed.
Another object is to surely mark a suspicious individual by mixing a paint with water to be discharged and making the paint wet. This makes it easy to identify the suspicious person after the fact.
In addition, it is also possible to use a tap water pressure as a water discharge pressure to enable water discharge in a distant place, and to ensure that a suspicious person is flooded even from a distance.
Another object is to increase the deterrent effect by using hot water as the water discharge.
Another object of the present invention is to easily install a security device by attaching a water discharge device to an existing sprinkler.
It should be noted that the above-mentioned object is an object that each invention achieves individually, and should not be construed as an individual invention achieving all the above-mentioned objects.
[0006]
Means for Solving the Problems and Effects of the Invention
The crime prevention device according to claim 1 is a crime prevention device for preventing intrusion and theft by a suspicious person, and is driven based on a crime prevention mode input switch for inputting a crime prevention mode and a crime prevention mode input switch. A suspicious person direction detection device that detects a suspicious person direction, a water discharge device that discharges water to a suspicious person based on the detection result of the suspicious person direction detection device, and a water discharge direction of the water discharge device that is based on the detection result of the suspicious person direction detection device. A rotating device for rotating in the direction of a suspicious individual, a control device for controlling a security mode input switch, a suspicious individual direction detecting device, a water discharge device, and a rotating device are provided. The security mode input switch is a switch for the control device to enter the security mode. The security mode input switch is, for example, a push switch that is manually pressed or a sensor switch that is automatically input. In the case of using a press switch that is pressed artificially, it is assumed that the switch substantially operates after a predetermined time has elapsed after the press of the press switch so as not to detect the presser as a suspicious person. The following devices operate in accordance with the ON of these security mode input switches.
[0007]
For example, when the security mode input switch is turned on by a sound collecting sensor or an impact sensor, the suspicious person direction detecting device detects the suspicious person direction according to a command from the control device. The suspicious person direction detecting device is, for example, an infrared camera device, a normal CCD camera device, an infrared sensor arranged in a ring, or the like. Then, when the control device detects the heat generated by the human body using, for example, one infrared sensor, the control device causes the rotating device to rotate, for example, the nozzle of the water discharge device or the entire water discharge device in the direction indicated by the sensor. The rotation device is, for example, a motor device that rotates the nozzle or the entire water discharge device in a horizontal direction by a gear. Then, a command is issued to the water discharge device to discharge water. Since the direction of the suspicious person and the water discharge direction substantially coincide, the suspicious person can be efficiently flooded. Thereby, further intrusion of a suspicious person can be suppressed.
When the security mode input switch is turned off, the security device does not operate. That is, it is possible to avoid a malfunction such as, for example, in the daytime, when a household member, a visitor, or the like is flooded. The security mode input switch can be operated only when necessary.
[0008]
The security device according to the second aspect is the security device according to the first aspect, wherein the security mode input switch is a push switch that is manually pressed, and / or a sensor switch that is automatically input according to a predetermined condition. It is characterized by being.
Various cases of intrusion and theft by a suspicious person are assumed. For example, there is a case where a window, a door, or the like is destroyed and enters regardless of day and night. In such a case, the predetermined condition is an abnormal sound of a predetermined value or more, and the sensor switch for detecting the abnormal sound is a security mode input switch. Thereby, the security mode can be immediately entered. That is, the security device according to claim 1 can be operated immediately.
[0009]
Also, for example, a suspicious person may enter at night without any abnormal sound. In this case, the predetermined condition is time. A sensor switch (timer switch) for automatically detecting time is a security mode input switch. That is, the security mode is automatically entered between predetermined times (for example, a period from evening to early morning of the next day). This eliminates the need for the consumer to turn on the push switch each time. The security device of claim 1 is automatically operated.
When the customer is away from home during the day, the push switch pressed by the customer is the security mode input switch. After the pressing switch is turned on, after a lapse of a predetermined time, the switch is substantially turned on, and a monitoring mode (security mode) is set. That is, the security mode can be artificially set. If the pressure switch which is pressed artificially and / or the sensor switch which is automatically input according to a predetermined condition is a security mode input switch, a security device which operates effectively in all cases can be provided.
[0010]
The crime prevention device according to claim 3 is the crime prevention device according to claim 1 or claim 2, wherein the suspicious person direction detection device includes a plurality of infrared sensors installed in a ring shape toward the outside, and a security mode. When the input switch is turned on, any one of the plurality of infrared sensors detects the suspicious person direction. Humans emit infrared light having a wavelength of several microns to several tens of microns depending on body temperature. Therefore, if an infrared sensor is used for the suspicious individual direction detection device, a suspicious individual can be detected regardless of day or night. If a plurality of such infrared sensors are installed in a ring shape toward the outside, the detection range becomes omnidirectional. That is, the direction of the suspicious individual can be reliably detected by any of the infrared sensors. Therefore, the security device can reliably detect a suspicious person regardless of day or night.
[0011]
A security device according to a fourth aspect is the security device according to any one of the first to third aspects, wherein the water discharge device includes a nozzle for vigorously discharging water to a distant place, and tap water pressure applied to the nozzle. And a valve for turning on and off the water supply. This water discharge device is configured to guide city water through a water pipe. For example, a city water pipe and a water guide pipe of the security device are connected by, for example, an electromagnetic valve. When discharging water in the security mode, the electromagnetic valve is opened. As a result, the tap water pressure is applied to the nozzle, and the tap water is vigorously discharged from the nozzle. Therefore, tap water is quickly discharged to a suspicious distant person.
[0012]
A security device according to a fifth aspect is the security device according to the fourth aspect, wherein the water pipe includes a paint tank that supplies paint to the water pipe. Thereby, the security device can spray the paint to the suspicious individual. The paint is, for example, a water-soluble paint, a water-soluble fluorescent paint, and an odorant paint. As a result, the suspicious individual is marked with the paint. If a suspicious individual is marked with paint, it can be easily identified after the fact.
[0013]
A security device according to a sixth aspect is the security device according to the fourth aspect, wherein the water discharge device has a heating device for heating a water pipe or a water channel. The heating device can heat the water pipe or the water in the water path. Thereby, the security device can discharge hot water to such an extent that it does not cause burns, for example. Therefore, intrusion of a suspicious person can be suppressed more effectively. It should be noted that the water introduction path means any path through which tap water flows. For example, it means a tank or the like provided on the way of the water pipe.
[0014]
A security device according to a seventh aspect is the security device according to the fourth or fifth aspect, wherein the water discharge device is installed on a sprinkler, and a sprinkler nozzle is used as a nozzle. The sprinkler has a water pipe and a sprinkler nozzle in advance. Therefore, a security device is configured using this sprinkler. That is, it is used as a sprinkler at normal times, and at security, the direction of the nozzle can be controlled during security to provide a security device. This can be properly used by, for example, turning on and off the engagement of the gear with the rotating device. That is, the gear engagement is turned off in the normal state, and turned on in the security mode. Thereby, the consumer can use both. ADVANTAGE OF THE INVENTION Since this invention can be installed in a sprinkler, it can be set as the security device excellent in convenience.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on embodiments. The present invention is not limited to the following embodiments (Examples)
FIG. 1 shows an example of the security device of the present embodiment. The figure is a configuration diagram. The security device of the present embodiment includes a sound collection sensor 11 as a security mode input switch, a push switch 12, a suspicious person direction detection device 20 including a plurality of infrared sensors 21, a water discharge device 30 for discharging water to a suspicious person, and a water discharge device 30. It comprises a rotating device 40 for rotating the nozzles 31 and a control device 50 for controlling them. As shown, the sound collecting sensor 11, the pressing switch 12, and the suspicious person direction detecting device 20 are arranged outside the housing 10. In the above configuration, the sound collection sensor 11 and the press switch 12 are security mode input switches. The sound collecting sensor 11 is a sensor that detects an intruding sound or an impulsive sound by a suspicious person day or night. The push switch 12 is a switch for artificially entering the security mode. Thereby, the security mode is automatically or artificially entered.
[0016]
The suspicious person direction detection device 20 is a device using an infrared sensor 21. Humans constantly emit infrared light having a wavelength of several microns to several tens of microns depending on body temperature. Therefore, if this sensor is used, a suspicious person can be detected regardless of day or night. The suspicious individual direction detection device 20 has eight infrared sensors 21 arranged in a ring shape outwardly as shown in the top view of FIG. Therefore, a suspicious individual can be detected for intrusion from any direction. That is, the output of any one of the infrared sensors 21 becomes large. For example, if the output of the infrared sensor 21a becomes large, the control device 50 can determine that a suspicious person has entered from the right.
[0017]
The water discharge device 30 includes a water guide pipe 32 for introducing tap water from a city water pipe (not shown), an electromagnetic valve 33 which is a valve for turning on / off (water guide / shut off) water, and a rotatable water guide pipe 32a. , A sprinkler nozzle 31 that is a nozzle for vigorously discharging water. A rotating device 40 including a gear G1, a gear G2, a motor device 41, and a rotating joint 42 is attached to the rotatable water guide pipe 32a. That is, when the motor device 41 is rotated by a command from the control device 40, the nozzle 31 is rotated via the gears G1 and G2.
[0018]
The control device 50 is, for example, a one-chip microcomputer including a CUP, a ROM, a RAM, an I / O, and the like. For example, each device described above is controlled by the CPU according to the procedure written in the ROM. For example, it is controlled according to the flowchart shown in FIG. To explain one example, first, in step s20, it is determined whether or not the security mode input switch is on. If no, it is in a normal state and returns to the start to repeat this routine. In the case of yes, for example, when an impact is detected by the sound collection sensor 11, it is determined that the security mode input switch is ON, and the process proceeds to the next step s21. Then, in Step s21, the infrared level (output level) of each infrared sensor 21 is detected from the suspicious individual direction detection device 20. Next, the process proceeds to step s22, and it is determined whether or not the infrared level of any one of the infrared sensors 21 is equal to or more than a predetermined value. If no, it is determined that the suspicious individual is not close enough, and the process waits until the suspicious person becomes equal to or more than a predetermined value. That is, the process returns to step s21.
[0019]
If it is determined in step s22 that the infrared level of any one of the infrared sensors 21 is equal to or higher than the predetermined value, that is, if yes, the process proceeds to step s23. Then, in step s23, the infrared sensor 21 is specified, and the difference between the infrared sensor 21 and the current angle of the sprinkler nozzle 31 is calculated. That is, the infrared sensor 21 is specified, and the rotation amount of the motor device 41 is calculated. Then, the process proceeds to step s24 to issue a command to the motor device 41 to rotate the sprinkler nozzle 31 in the direction of the suspicious individual. Finally, the process proceeds to step s25, where the electromagnetic valve 33 is opened to discharge water to the suspicious individual. That is, when the electromagnetic valve 33 is opened, the tap water is guided to the water conduits 32 and 32a, and is discharged from the sprinkler nozzle 31 with vigor. That is, the suspicious person is reliably flooded with the tap water. Thereby, further intrusion of a suspicious person can be suppressed.
[0020]
Note that the security device of this embodiment operates as a normal sprinkler except in the security mode. In this case, for example, the gear G2 and the gear G1 of the rotating device 40 are manually turned off, and the electromagnetic valve 33 is opened by a switch (not shown). Since the sprinkler nozzle 31 is rotatable, the sprinkler nozzle 31 discharges water while rotating due to the action reaction caused by water discharge. That is, the security device of this embodiment can be used also as a normal sprinkler. That is, a security device excellent in convenience can be obtained.
[0021]
(Modification)
The above embodiment is an example of the embodiment of the present invention, and various other modifications are possible. FIG. 4 shows an example of a modification of the security device of the present embodiment. The figure is a configuration diagram. The security device of the above embodiment is an example of discharging tap water to a suspicious individual. In this case, if the suspicious person is small in the amount of water, there is no deterrent effect. Also, it becomes difficult to identify the suspicious person after the fact. The purpose of the present embodiment is to increase the deterrent effect and to facilitate subsequent suspicious individual identification. Therefore, the water guide pipe 32 of the security device of this embodiment includes a tank 35 for filling the paint 34 and a paint introduction pipe 36. That is, the paint 34 is previously filled in the paint tank 35 via the check valve 37. The paint 34 is, for example, a water-soluble paint, a water-soluble fluorescent paint, or an odor paint. In this state, when the electromagnetic valve 33 is opened as in the embodiment, the paint 34 diluted with tap water is vigorously jetted from the sprinkler nozzle 31. Thus, the suspicious individual is marked with a large amount of, for example, a fluorescent paint or an odor paint. Since it is marked, a deterrent effect can be expected. Further, if the marking is performed, the intruder can be easily specified after the fact. Such a configuration may be adopted.
[0022]
Further, in the above-described embodiment, water is discharged to the suspicious person, but hot water may be used. For this purpose, as shown in FIG. 5, a heater 39 as a heating device may be provided in a part of the water pipe 32. Since the suspicious person is exposed to the hot water, the intrusion is more effectively suppressed. Although not shown, when the paint tank 35 is provided, the paint tank 35 may of course be provided with a heating device. There is a similar effect.
[0023]
In the above embodiment, the sound collection sensor 11 or the press switch 12 is a security mode input switch, but this may be automatically input according to the time. For example, a sensor switch (timer switch) for detecting time is set as a security mode input switch. For example, the security mode is automatically set from the evening to a predetermined time in the next morning. With this configuration, the security device can be automatically turned on even if the suspicious individual is not detected by the sound collection sensor 11. Therefore, a more secure security device can be provided.
[0024]
Further, in the above embodiment, a garden sprinkler for sprinkling water outdoors is assumed. However, a sprinkler for fire extinguishing with a ceiling in a room may be used. If you have a water pipe, you can easily install it on it. The water discharging device is not limited to a sprinkler, and any water discharging device having a limited water discharging range may be used as long as it has a water discharging port in addition to water discharging by a nozzle.
