Description

[Detailed explanation of the invention] Conventionally, police officers and security personnel carry flashlights when patrolling and monitoring at night, and the human eye can detect abnormalities that are illuminated by the visible light of the flashlight. This is what we are trying to discover.

However, the human eye has its own limitations in being able to do this with the dim light of a flashlight, and even if you try to use a bright flashlight, this also has its limits as a portable device.

In addition, the use of a flashlight makes it clear where the person carrying the flashlight is and can warn of intruders in advance.

In addition, passive intruder alarms that receive infrared rays emitted by the human body can be used in areas where intruders can easily enter the building, such as openings in the building.
In the past, alarms have been installed indoors, in hallways, on doors, etc., or even outside in areas where intruders are particularly likely to enter, to issue an alarm, but these are not only fixed to those locations, but also alarms. , it does not even take into account the tracking of the intruder's actions.

Unlike these fixed intruder alarms, the portable composite body sensor of the present invention is portable and can track abnormal intruders, and also has the function of a flashlight. It is very convenient for security personnel such as the following to carry this.

One embodiment of the present invention will be described with reference to the drawings.

The drawing is a cross-sectional view of the portable composite body sensor of the present invention, which is an example of using a pyroelectric detector.

An infrared solid state detector 2 is placed at the focal point of the concave mirror 1, and a plastic film or the like 5 that passes infrared rays (wavelength 7 to 15 μm) including human body radiation is attached as a window of the optical system.

The signal from the detector 2 is passed through an electric circuit 3 and displayed on an alarm signal (buzzer, light signal, etc.) 4.

Further, the flashlight may have the same structure as a conventional flashlight, which is equipped with a switch 9 and can be used together with the flashlight 10 or switched by switching the switch 9.

That is, a lens 7 is placed in front, and a light bulb 6 is placed behind it.
A battery 8 is provided at the rear, and the switch 9 causes the light to blink.

The battery 8 can also be used as a power source for driving the electric circuit 3.

Note that 11 is a handle. In this example, the body sensor and flashlight are placed above and below each other, but the positional relationship may be left or right, front or back, and the light bulb can be installed on the focal point of the same mirror as the detector 2, using the concave mirror 1. It can also be used as a lens 70 by reflecting light.

In addition, other infrared solid-state detectors such as a thermistor thermopile, Pbs, or Pb5e infrared light emitting diode can also be used.

Since the present invention has the above configuration, it is possible to carry this composite sensor and inspect the surroundings using the body sensor, and if an abnormal signal is detected, shine a flashlight on it and track it using this and the body sensor.

And if necessary, it can be detected without turning on the flashlight, so the security personnel can detect an intruder even if the intruder does not know their whereabouts, and then turn on the flashlight. This is convenient because you can also use it.
