Description

Remote theft prevention and remote call indication system

The present invention relates to a remote theft prevention and remote call indication system, and more particularly, remote theft prevention and remote call indication to alert the owner to a stolen or lost state when valuables deviate from a certain distance from the owner. It is about the system.

In general, if a person carrying a bag of valuables or cash travels in a car and arrives at its destination, it may be disastrous to leave the bag in the car, causing mental and economic losses. In addition, in crowded places and streets crowded with amusement parks, parks, baseball fields, and the like, caregiving of children may be inadvertent, resulting in the loss of kings and lost children. As a solution, it was best to give the bag or the child a name tag or an engraved name.

In order to solve such a problem, the applicant has devised a utility model registration application No.23595 filed on November 11, 1993, that is, valuables theft and loss prevention device, and the gist of the utility model registration application is as follows. .

First, the transmitter is composed of a power supply unit consisting of a battery and a power switch for supplying a 1.5V DC power supply, a converter and peripheral resistance for supplying the battery voltage to a circuit by making a 5V stabilized boost power supply. 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 always 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, due to the development of information and communication, wireless mobile communication devices (hereinafter referred to as 'personal mobile communication devices') that can be carried one by one are being developed. As a result, everyone tends to carry this personal mobile device. As personal mobile communication devices are gradually advanced and miniaturized, there is a problem that loss and theft often occur.

The present invention has been made to solve the above problems, to reduce the power loss of the transmitting device and to prevent the interference of the receiving device to improve the function, and to be easily removable to the personal mobile communication device, the loss in advance The aim is to provide a remote theft prevention and remote call indication system that can be prevented.

On the other hand, when the transmitter 10 is installed in a personal mobile communication device, a current notification buzzer and vibrator (not shown) in the personal mobile communication device and the current between the buzzer and the vibrator between the transmitter 10 is detected. And a reception detecting unit 14 for outputting an incoming signal. Then, the transmitting unit 10 has a function of remotely transmitting the first identification code signal and the second identification code signal at a specific natural frequency based on the incoming signal generated from the reception detection unit 14, and checking the code.

The first warning part is a flashing light 51 for visually blinking and displaying, the second warning part is an alarm generating part 52 for visually alerting the user, and a vibration generating part 53 for displaying the vibration so that the user feels the vibration. Has

When the transmission unit 10 and the reception detection unit 14 as described above are attached to the personal mobile communication device, as shown in FIG. 3. That is, the detachable unit 60 is provided to be detachably installed at one side of the personal portable communication device 70 by accommodating the transmitter 10, and the transmitter 10 installed in the detachable unit 60 is a communication device ( It is powered by the dedicated battery 71 of 70). On one side of the personal portable communication device 70 opposite to the detachable portion 60, a detachable groove 75 having a receiving space is formed so that the detachable portion 60 is installed.

The code generator 11 is formed of an encoder chip for generating an identification code, and the high frequency transmitter 12 generates a predetermined natural frequency to synthesize the transistor for switching the identification code and the identification code switched in the transistor.

Operations of the remote theft prevention and remote call indication system as described above are as shown in FIGS. 4 and 5.

First, when the reception detecting unit 14 detects an incoming call from the buzzer and the vibrator of the personal mobile communication device (S10), the code generating unit 11 of the transmitting unit 10 generates the first identification code signal (S20). If the incoming call is not detected, a second identification code signal is generated (S30). The first and second identification code signals are synthesized into a predetermined natural frequency signal generated by the high frequency transmitter 12 of the transmitter 10 (S40), and the output voltage is applied to the synthesized signal by applying the outgoing voltage. (S60). This is a case where the transmitter 10 is attached to the personal portable transmitter. On the other hand, when the transmitter 10 is attached to another bag, that is, a bag in which valuables are stored, the incoming call detection unit 14 does not operate and the code generator 11 generates a second identification code signal.

Then, the predetermined natural frequency signal having the first and second identification code signals is received by the high frequency removing unit 20 (S70) and the components of the high frequency for detecting the first and second identification code signals are removed ( In operation S80, the first and second identification code signals from which the high frequency is removed are detected by the code detector 30 and amplified to a predetermined size (S90).
