Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

1 is a perspective view showing the structure of the wallet loss prevention device of the present invention, Figure 2 is a block diagram showing the structure of the wallet loss prevention device of the present invention.

First, the present invention will be described with reference to FIGS. 1 and 2.

The apparatus for preventing the loss of a purse of the present invention includes a transmission and reception device (28, 10) for transmitting and receiving radio waves, a vibration device (22) for generating vibration by receiving the radio wave generated by the transmission device (28) It consists of a vibrating tool 24 for amplifying.

The transceiver is not described in detail because it uses a general wireless transmission technology.

Schematically, first, the transmitter 28-RF tag-locates and identifies the position of the tagged object in the stationary or moving state and transmits information about the state of those objects.

The electronics on the transponder are powered by the RF power transmitted by the base station at the carrier frequency and received by the antenna on the tag.

The signal extracted by the tag antenna induces an AC current rectified by the RF diode to the antenna, and the rectified current is used for the power supply of the electronic device.

The tag antenna loading is changed by something to be measured, i.e. microphone resistance. From the incoming RF energy, the oscillation current induced in the tag antenna is changed, and the change in the oscillation current changes the RF power radiated from the tag antenna.

Since the change in power dissipated from the tag antenna is taken out by the base station antenna, the microphone effectively distributes the power without itself having a built-in power supply.

The antenna current oscillates at harmonics of the carrier frequency because the diode current contains a frequency component that is doubled.

The frequency at this time is taken out from the carrier frequency and sorted out more easily than just reflected.

This type of tag does not have its own power source, so it is called a passive tag to distinguish it from an active tag containing a battery.

The battery supplies energy to spread the information from the tag antenna. The active tag changes the loading on the tag antenna to send information to the base station.

It is also possible to use tags with logic and read / write memory. In this case, the tag can identify the animal by measuring some characteristic—the animal's temperature. At this time, the antenna load is changed by the transistor.

On the other hand, as described above, the conventional prior art tag uses basic electronic logic, memory circuit, receiving circuit, and modulation circuit to receive information from the base station and transmit information from the tag to the base station.

In addition, with the development of semiconductor technology for miniaturization, high speed, and low power, the function can be greatly increased, and the price of the tag is also low.

Currently available research and development technologies may enable new functions and a variety of products in communication technology.

On the other hand, the range of communication distances from the base station to the tag branch is very important. This range is determined by the voltage formed by the antenna on the tag and the rectifier circuit.

First, in order to power a device on a tag, a stable supply voltage is extracted from the modulated RF field, and then a data signal with well defined zeros and ones for use of the tag digital electronics is recovered from the modulated RF field. In addition, the RF tag information receiving device draws power from a main power capacitor supplying power to the tag when no RF power is transmitted from the base station.

In addition, the RFID tag is classified into an active type which has a built-in power source and a passive type that generates power for driving an internal circuit from the RF input from the antenna and can be used according to need.

The present invention utilizes the general communication between the RF base station and the RFID tag as described above, and uses the technology using the passive type RFID tag, and connects and installs a vibration generating device and an amplifying vibrating device for amplifying the vibration. It is configured by.
