Abstract

PROBLEM TO BE SOLVED: To provide a security device to detect the theft, tricks, etc., in an automobile, etc. SOLUTION: This security device comprises a detection part 4 using a sensor, a transmission part 5 such as an alarming speaker, and a resetting part 6 using a setting/resetting panel by a cigar plug to be inserted in a cigarette socket of the automobile or a plurality of buttons. A piezoelectric element type or pyroelectric type sensor is employed in the detection part 4 to sense the vibration, shock in or approach of a living thing to the automobile. The transmission part 5 is set to be operated after the specified time when the change in the vibration and temperature appears at the predetermined frequency within the predetermined time. The system is reset when an owner of the automobile inserts a key in a key socket and turns it, or when the button pressing order of the resetting part 6 is agreed with the stored order of the buttons pressed after the specified time after the sensor is reacted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to theft in automobiles and the like,
A security system for detecting mischief and the like is disclosed.

[0002]

2. Description of the Related Art
In a parked car, a system is used for detecting a theft, mischief, etc., using a human body detection or vibration sensor 1 to sound an alarm after a reaction (FIG. 1) or wirelessly contacting the user (FIG. 2). Was. The system is released by radio or a switch. In the case of radio, the system cannot be constructed at a low cost, and the reliability of operation is inferior to that of a switch due to the surrounding radio wave conditions. In the case of a switch, it is difficult to install it in a place where only the user himself can understand, and in order to prevent the user from responding to the sensor and sounding an alarm, for example, exclude the range necessary to press the switch in the range of human body detection Ingenuity such as is required.

[0003]

The structure of the present invention (FIG. 3) includes a detecting section 4 using a sensor, a transmitting section 5 such as an alarm speaker, and a cigar plug (FIG. 4) or a plurality of buttons to be inserted into a cigarette socket of an automobile. And a release unit 6 using a setting / release panel (FIG. 5). The detection unit uses a piezoelectric element or a pyroelectric sensor to detect vibration, impact, or the approach of a living thing in a parked automobile. At this time, if the transmitter is actuated immediately by the reaction of the sensor, if it is accidental (for example, a large truck passes next to it when using a vibration sensor), it will malfunction and an alarm sound will not be heard by nearby people. Can give pleasure.

Therefore, when vibration and temperature change appear a predetermined number of times within a predetermined time, the transmission unit is set to operate after a lapse of a predetermined time. Also, when the vehicle user returns, it is released within a certain period of time until the transmission unit operates after the sensor reaction.

[0005] In the release of the system, the owner of the car,
When the user inserts the key of the car into the key socket of the car and turns the engine to the start or accessory position, the security system is released when a voltage exceeding a certain value appears at the terminal of the cigar socket in the car. .

[0006] As another method, the system user presses a plurality of buttons when leaving the vehicle in advance, memorizes the order in which the buttons are pressed, sets the security system in a monitoring state, and activates the button which is pressed at a certain time after the sensor response. If the order matches the stored one, release it. In this case, if the case where one button is pressed a plurality of times is included, various combinations of the order of the buttons to be pressed before the release are considered are possible.

When a battery is used as a power source of the security system, if the battery is always kept in a monitoring state, the battery is exhausted and the battery must be replaced frequently. To turn on the power only when the user wants to use it, a switch must be provided in the power supply. However, if the intruder easily turns off the power, the system does not play a role. Therefore, the circuit in FIG. 6 is added to the system power supply side. A switching circuit b having a switch control terminal k at one end of a power supply e (secondary power supply) provided with a connection terminal i to a power supply side f such as a battery and switched to fg or fe by a slide switch a
, And then to the system power supply j, and the other end to the power supply detection circuit 1. During normal monitoring, the slide switch is generally at the position d and supplies power to the system. When the slide switch almost reaches the position c, the power of the system itself is turned off by controlling the switch control terminal after a certain period of time has elapsed after detecting a change in power. When the intruder operates the switch, the transmission unit operates, for example, an alarm continues to sound because the system is operating for a certain period of time until the power is turned off unless the above-described release method is used. The user performs the above-described cancellation before and after operating the switch. Note that the capacitor m is for preventing the system from being turned off when the slide switch is operated. As described above, the power can be turned off except when the battery is used, and the battery can be used for a long time. As an application, the system shown in FIG. 4 is used to connect a power supply from a cigarette lighter to the power supply detection circuit and set the system to be able to be turned on / off only when the cigarette lighter is turned on. Otherwise, a system that cannot control the power supply of the system can be constructed (FIG. 7).

[0008]

Until now, the only way to release a security system such as a theft or mischief in a parked car is to use an expensive and unreliable wireless method or to use a switch with a reduced range of sensors. In the present invention, the owner and the user of the vehicle can release the system without fail. In the method using a car key, a cigar socket is used, so a portable system can be constructed by using a battery as a power source, so the user can easily install and remove it without special knowledge even without specialized knowledge It can be easily installed on other cars. As with the former, the PIN code method is portable and installed,
There is a pleasure that the user can freely remove and set the number freely each time. Also, for example, even when the number of buttons is only three, if one button is pressed several times, the order of buttons to be pressed before release can be various combinations, and others who do not know the number can release it in a short time. It is impossible at first. In addition, even if the existence of both types is revealed, it does not assist the release method except by the user, but rather is useful in the sense of crime prevention. When a battery is used as the power supply, the above-described system can be used to turn off the power supply except when the battery is used, leading to energy saving. In addition, it can also be used as an accessory in the car depending on the design, so that it can be enjoyed visually on the drive.
