A constant voltage supply part, an oscillator part comprising two inverters, a capacitor and a resistor, a setting part consisting of a coil and a capacitor, a signal amplifier part consisting of a trimmer of a transistor, and a signal connected to the collector terminal and outputted It consists of a transmission output control unit composed of a transmission force control switch and a resistor for adjusting the strength of the signal, the configuration of the receiver comprises a receiver for receiving a signal transmitted from the transmission output control unit, and amplifying the signal to a predetermined signal size It consists of signal amplification circuit, alarm drive circuit, timer circuit, power supply circuit, and battery voltage check circuit. have.

The transmitter is attached to a bag or a child to transmit a predetermined signal, and the receiver is attached to a place where the owner of the bag or the guardian of the child easily stands out and constantly monitors the reception state of the transmitted signal. Therefore, if a person wearing a transmitter or a person walks away from or away from a certain distance that can be received by the receiver, an alarm is generated at the receiver, thus losing the bag and theft or losing children. To prevent it.

However, the conventional valuables theft and loss prevention device has a short life due to the high power loss caused by boosting the voltage of 1.5V to the voltage of 5V in the converter of the constant voltage supply part, and thus has a short lifespan. If the transmission and reception to prevent theft in the area, there is a problem that can not prevent the lost state of the bag or the lost state of the child due to crosstalk between the receiving devices.

In addition, if a valuable device such as a child or a bag with a receiver is lost or lost, it is difficult to cope in an instant situation because it does not warn the child or a person with valuables, and thus the lost location. There is a problem that it is difficult to recover quickly without knowing.

Meanwhile, due to the development of information and communication, wireless mobile communication devices (hereinafter referred to as 'personal portable communication devices') that can be carried one by one are being developed. Recently, the convenience that is not restricted by place and time has been developed. As a result, everyone tends to carry this personal mobile device. However, since personal handheld communication devices are gradually advanced and miniaturized, loss and theft often occur, which can be prevented by Utility Model Application No. 23595 filed by the present applicant, but it is not known where it is actually lost for a long time. There is a problem that occurs while looking for a king.

The present invention has been made to solve the above problems, to provide a bidirectional loss prevention system for bidirectional loss prevention communication so that valuables such as bags and personal portable communication devices can easily know where the lost. have.

First, the bidirectional anti-theft system has a location notification unit and the anti-theft unit. When the location notification unit is spaced apart from the anti-theft unit by a predetermined distance, the location notification unit is attached to an object such as a bag or valuables and informs the owner of the lost location at least either by sight or hearing, or steals the object. It is to tell the location of the theft of the thief, and the antitheft unit is always owned by the owner and the location notification unit by a predetermined distance to inform the owner of the lost situation in at least one of sight, hearing and touch.

As shown in FIG. 1, the position notification part and the anti-theft part of the bidirectional anti-theft system, as shown in FIG. 1, intermittently transmit a plurality of identification code signals as a specific natural frequency signal, and from the transmitter 10. A high frequency removing unit 20 for receiving a natural frequency signal to remove high frequency, a code detecting unit 30 for detecting and amplifying an identification code signal from the high frequency removing unit 20, and the transmitting unit 10 for transmitting the identification code signal. And a code checking and generating unit 40 for selectively outputting an alarm signal corresponding to theft by comparing the identification code signal of the code detector 30 with the radio wave strength and mood code signal and its radio wave strength. At least one of the flashing light 51 for visually blinking and the alarm generating unit 52 for audibly alarming and the vibrating generating unit 53 for tactilely vibrating display the warning of the code checking and generating unit 40. Receiving the signal has a warning unit 50 for warning the user.

That is, the present invention has a position notification unit having a transmitting unit 10, a high frequency removing unit 20, a code detecting unit 30, a code checking and generating unit 40, and a warning unit 50, and the same components. On the grounds of having an anti-theft department,

Any one of the position notification unit and the anti-theft unit is a transmission unit 10 for transmitting a plurality of different identification code signals intermittently from one side toward the other side of the other as a specific specific natural frequency signal, and the other side A high frequency removing unit 20 for receiving a natural frequency signal transmitted from the transmitting unit 10 on one side to remove high frequency, and a code detecting unit detecting and amplifying an identification code signal from the high frequency removing unit 20 ( 30), and the identification code signal is applied to the transmitter 10 so as to transmit a frequency signal having a code signal, the identification code signal of the code detector 30, its propagation intensity and reference code signal, and its propagation intensity A code checking and generating unit 40 for selectively outputting a warning signal corresponding to the loss and theft of an object attached to one side by comparing with the code checking and generating At least any one of a warning signal on the basis of the unit 40 visual and auditory and tactile sense to the user and has a warning unit 50 for warning the loss of the goods. At this time, the power supply unit 60 for supplying predetermined power to the transmitter 10, the code detector 30, the code check and generator 40, and the warning unit 50 includes a position notification unit and an anti-theft unit. Is provided.

In fact, the frequency signal from the transmitter 10 of the position notification part is transmitted to the high frequency removing part 20 of the antitheft part, while the frequency signal from the transmitter 10 of the antitheft part is a high frequency agent of the position notification part. A component, which is transmitted to the rejection 20 and processes each of these signals, is also provided in each of the location notification unit and the anti-theft unit. Accordingly, the code checking and generating unit 40 compares the identification code signal and its propagation intensity from each other with the reference code signal and the propagation intensity thereof so that the code signal is not the same or the propagation intensity of the identification code signal is When it is lower than the radio wave strength of the reference code signal, it recognizes that the location notification unit and theft prevention unit is separated by more than a predetermined separation distance to generate a warning signal. Then, when the warning signal from the code check and generation unit 40 is applied, the warning unit 50 of the position notification unit, the blinking light to inform the user of the location of the object to which the current position notification unit is attached by visually blinking display 51 and an alarm generating unit 52 for notifying the user of the position of the object by an audible alarm sound, and under the same conditions, the warning unit 50 of the anti-theft unit has a visual flashing indication to the user. The flashing light 51 for notifying that the object attached to the current location notification part is lost, the alarm generating unit 52 for notifying the user that the object was stolen by an audible alarm sound, and the user by the tactile vibration It has a vibration display unit 53 to inform that theft and lost.

On the other hand, when the location notification unit of the two-way anti-theft system is embedded in the personal mobile communication device, as shown in Figure 2, the intermittent plurality of different identification code signal to the transmission unit 10 of the anti-theft A transmitter 10 for transmitting a natural frequency signal, a high frequency remover 20 for receiving a high frequency signal from the anti-theft transmitter 10, and removing high frequencies, and an identification code signal from the high frequency remover 20 Code detection unit 30 for detecting and amplifying the signal between the buzzer and vibrator 48 and the transmitter 10 in the personal mobile communication device and outputs an incoming signal by detecting a power current from the buzzer and the vibrator It has a reception detecting unit 44. In addition, different identification code signals are applied to the transmitting unit 10 according to the incoming signal of the incoming detection unit 44, and the different identification code signals passed through the high frequency removing unit 20 and the code detection unit 30. When the same as the corresponding reference code signal, if the different identification code signal is not the same outputs different first and second warning signal separately, and the identification code signal of the code detection unit 30 and The apparatus further includes a code checking and generating unit 40 for selectively outputting an alarm signal corresponding to theft by comparing the radio wave intensity and the reference code signal with the radio wave intensity thereof, and visually blinking and displaying the flashing light 51 and the audio. At least one of the alarm generating unit 52 and the vibration generating unit 53 tactilely displaying the vibration to warn the user to receive the first and second warning signals of the code check and generation unit 40 to warn the user part( 50) In fact, the warning unit 50 operates the blinker 51 to notify the incoming call when the first warning signal is required for communication connection from the other side to the personal portable communication device, and the anti-theft unit when the second warning signal is used. As the distance from each other gradually increases, the alarm generating unit 52, the vibration display unit 53, and the flashing light 51 are operated simultaneously to inform theft and loss. At this time, in case of loss or theft, the anti-theft unit operates in almost the same anti-theft mode mechanism to operate the alarm generating unit 52, the vibration display unit 53, and the flashing light 51 at the same time. Warn against loss.

In addition, the wireless mobile communication device generates a positioning signal in a slot cycle in order to check the location of the base station and each other, the positioning signal has a unique code set for each communication device, the location confirmed when a call is received To generate an incoming signal. In this case, slot cycles typically occur intermittently, considering slot 2, which is currently the MSM Chip standard, that is, high reception rate and battery consumption. At this time, slot 2 is 5.12 seconds, and in some cases, the slot can be adjusted by changing the slot.

Such a positioning signal has a constant transmission output, and if the anti-theft unit 200 of the present invention is adjusted to have a resonance frequency corresponding to the frequency of the positioning signal, it may indicate whether theft is detected.

That is, the anti-theft unit 20 receives the positioning signal from the high frequency removing unit 20 and the code detecting unit 30 to detect the identification code signal, and the identification code signal detected by the code checking and generating unit 40 and its propagation. When the detected radio wave intensity decreases as the deviation distance increases by comparing the strength with the reference code signal and the radio wave intensity, it is determined that theft is generated and a warning signal is generated. Alarm or vibrate and blink indicators. Here, when the communication is connected from the other side to the built-in or equipped personal portable communication device from the other side, the warning unit 50 of the anti-theft unit tells the user that the incoming situation only by the blinking display of blinking light.

In addition, the code checking and generating unit 40 may be further provided with a switching unit (not shown) to operate in any one of the communication start mode and the loss prevention mode as described above.

When the transmitter 10 and the call detection unit 44 of the position notification unit as described above are detachably attached to the personal portable communication device, as shown in FIG. 3. That is, the detachable part 73 is provided to be detachably installed on one side of the personal mobile communication device 70 by accommodating the transmitter 10, and the transmitter 10 installed in the detachable part 73 is a communication device ( It is powered by the dedicated battery 75 of 70). On one side of the personal portable communication device 70 opposite to the detachable portion 73, a detachable groove 77 having a receiving space is formed so that the detachable portion 73 is installed.

The code checking and generating unit 40 is formed of an encoder chip that generates an identification code and has a discriminating function. The transmitting unit 10 is configured to synthesize the transistor for switching the identification code and the identification code switched in the transistor. It has an LC oscillator that generates a natural frequency and outputs it as outgoing voltage.

The high frequency removing unit 20 is composed of a capacitor for removing the high frequency in response to the natural frequency signal transmitted from the LC oscillator, and a transistor for outputting an identification code signal from the removed natural frequency signal, the code detection unit 30 And a feedback amplifier circuit for amplifying the identification code signal and at least one nose detection gate for detecting the identification code from the amplified signal. The code checking and generating unit 40 has a decoder chip that compares radio wave strength as well as comparing whether the identified code matches the reference code, and outputs a warning signal or recognizes an incoming call if the result is not identical.

The present invention can reduce the power loss of the location notification unit and the anti-theft unit to improve the life, and because the anti-theft communication is made in both directions between the location notification unit and the anti-theft unit, if the object attached to the location notification unit is stolen and lost Theft prevention unit as well as the positioning unit to warn users of the lost and stolen situation to recognize the loss and theft quickly, in particular, it is easy to know the location of the lost and stolen goods, and steal the goods Anyone can know the location of the stolen thief because it has the effect of maximizing the convenience according to the improved function to prevent theft in advance.

In addition, since it can be easily attached to or detached from a personal mobile communication device, it is possible to completely eliminate the economic loss and inconvenience of the user by preventing the loss of the personal mobile communication device, which is a necessity of the modern man, in advance.

In particular, since the remote display and alarm can be received silently from the personal mobile communication device, there is an effect that can quickly grasp the incoming state in the cinema or place to be solemnly maintained.
