DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a security device for security of valuable items such as valuables and an alarm device for protecting and avoiding people and animals from dangerous materials.

[0002]

2. Description of the Related Art A conventional alarm device uses either an audible alarm or light from an incandescent bulb when a person or animal to be detected approaches a protected or dangerous object as a detected object. , A warning was issued to the owner of the detection target or the detected object.

[0003]

In a conventional alarm device, when a person or an animal to be detected approaches, a user issues an alarm according to the type of a maintenance object or a dangerous object, the installation environment, or the characteristics of the detection object. The method of notifying was determined by judging whether sound or light from an incandescent bulb was effective, and the one that could be expected to be more effective was selected and installed. If the effect is weak, a new alarm device with the other function must be installed, which not only requires cost and labor, but also has a problem in reliability in that no measures can be taken during this time.

[0004] Light from incandescent bulbs is suitable for monitoring the behavior of suspicious persons or detection targets by illuminating the user at a short distance at night and monitoring the behavior of a suspicious individual or a detection target. However, there is a problem of visibility such as insufficient light quantity. In the alarm device, the distance sensor and the alarm output circuit are arranged in the same housing, so if the distance between the user and the maintenance object is remote, it cannot be used or other equipment that newly recognizes the alarm remotely Was needed.

[0005] In the case of using animals such as dogs and birds to enter houses and avoid dangerous objects, the objects become accustomed to the sound and light of the alarm device (learning). There was a problem of not continuing.

The present invention has been made to solve such a problem, and an object of the present invention is to surely inform the user of the apparatus or a detection target that the user has approached the object, avoid a danger of being involved, An object of the present invention is to provide a highly reliable alarm device for preserving property.

A circuit (11), an integration circuit (12) for not detecting the movement of the detection target within a short distance within the detection distance, and an output circuit (13) for notifying the user or the detection target itself that the detection target has approached. The output circuit comprises an alarm sound generating circuit (13A) for generating an alarm sound, and a strobe circuit (13B) for notifying by light. The power supply circuit (14) supplies power to each of the above circuits. With this configuration, a warning to a user or a detection target can be made by sound and flash light.

In the alarm device according to the second aspect of the present invention, since the output unit is constituted by the alarm sound generating circuit for notifying by sound and the high frequency circuit for notifying by radio wave, the alarm to the user or the detection target is sounded. It can be done by radio waves. The detection target is notified by sound, and a remote user can monitor by preparing a radio wave receiving circuit.

In the alarm device according to the third aspect of the present invention, since the output unit is constituted by an alarm sound generating circuit for notifying by sound, a strobe circuit for notifying by flash light, and a high frequency circuit for notifying by radio wave, the user is provided. And alarm to the detection target can be performed by sound, flash light and radio waves. The detection target is notified by sound and flash light, and a remote user can monitor by providing a radio wave receiving circuit.

In the alarm device according to the fourth aspect of the present invention, the output unit is constituted by a strobe circuit for notifying by flash light and a high-frequency circuit for notifying by radio wave, so that an alarm to a user or a detection target is sound and flash. Can be done with light. The detection target is notified by flash light, and a remote user can monitor by preparing a radio wave receiving circuit.

In the alarm device according to the fifth aspect of the present invention, since the sensor / distance detection circuit and the integration circuit / output section are separated from each other and arranged in individual housings, flexibility can be obtained at a place where the alarm / circuit is installed. The casings are wired or wirelessly linked and function in the same manner as the alarm device described above. However, since they function independently of each other, testing and evaluation of each unit can be facilitated.

In the alarm device according to a sixth aspect of the present invention, in the alarm sound generating circuit, the frequency, tone, and intermittent period of the alarm sound can be arbitrarily or automatically changed. In the apparatus, the light amount, light color, and light emission cycle can be arbitrarily or automatically changed in the strobe circuit. Thereby, when an animal such as a dog or a bird is set as a detection target, a complicated alarm sound and light are generated, and it is possible to make the learning difficult.

According to the alarm device of the present invention, in the strobe circuit, the output of the detection circuit is used as the input of the phototransistor to operate the discharge tube and emit light continuously. Warning can be performed more reliably.
