JP2003099862A - Security by inclination/vibration sensor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a safe, simple, and low-cost security monitoring device for a mechanism. SOLUTION: The movement, fracture or vibration of a substance is detected by using this inclination/vibration sensor electrically turned on/off by the moving of a conductive ball in a case, and a detecting signal is ID coded and transmitted by radio signals. On the other hand, the transmitted radio signals are received by a receiver and the ID code is interpreted and used as an alarm signal.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects an illegal movement of an important object or commodity, and uses a cordless remote place to invade an invader other than a party or an important object. Is a security device that allows you to know theft of a computer. Also, besides security, it detects abnormal vibration and abnormal acceleration of mechanical equipment and can be notified cordlessly to a remote place by a transmission medium such as radio waves, so that the signal can be used for alarm at the receiving side. Not
It can be recorded on a computer. 2. Description of the Related Art Conventionally, this type of apparatus has to be installed in a place to be directly monitored or installed in a separate room such as a control room by a wire, so that the field of use is narrow and the cost is high. It was difficult to install in places where there were no people or where the human body was in danger. Also, because it is not cordless,
There were problems with free installation and safety. [0003] The inclination and vibration of an object are detected by a sensor, the detected signal is converted into an ID code, and a cordless system is realized by using a transmission medium such as a radio wave. Things. A signal detected by a tilt / vibration sensor which is electrically turned ON / OFF by movement of a conductive ball in a case is ID-coded, and this signal is used as a modulation signal as an electric wave or the like. Modulation of the transmission medium. The modulated signal is radiated outside through the transmission output circuit.
By forming these circuits into a unit to make the sensor unit compact, a small and inexpensive sensor unit can be obtained. On the other hand, a transmission medium signal such as a radiated radio wave is received, and information on an abnormal object is output to the outside through an output circuit through an ID code decoding circuit that decodes an ID code. Figure 1 of [Document Name] Drawing
Will be described. This is a filter circuit made up of a sensor, a resistor R and a capacitor C. Circuit. Modulation circuit that modulates the carrier. is. The above is a compact unit that transmits tilt and vibration signals. A receiving circuit that receives the transmission medium signal. Code decoding circuit. According to the present invention, by installing the apparatus in a dangerous place or a place where no one is present, such as at night, the intrusion of a person other than the party or theft of an article is detected, and an alarm is issued or recorded. Not only can it be used for security such as
By making it cordless, safety can be ensured. Further, since abnormal vibration and acceleration in a dangerous place such as a mechanical device can be detected by an unmanned person, it is expected that industrial use value is extremely high. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A typical embodiment is cordless by being installed in an important art object, an expensive product, a safe, a vending machine, a showcase, and the like. Therefore, it is possible to safely record or record an alarm at a place remote from the site. In addition, by installing it at gates, doors, windows, etc., it is possible to detect the intrusion of a suspicious person other than the person concerned, so it is possible to know the intrusion of the suspicious person immediately before the room where the person concerned is in, so it is more secure Security can be constructed inexpensively and easily. In an industrial setting, installation on a mechanical device in a dangerous place has an effect that abnormality of the mechanical device can be constantly monitored.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. A sensor transmission unit that integrates the above circuits in a compact manner. The battery can be used as a power source to enable free installation. A receiver incorporating the above circuit. [Explanation of symbols] The sensor indicates a tilt / vibration sensor. R is a resistor, C
Indicates the capacity.
