That is, the receiving unit 201 for receiving the signal transmitted from the remote control transmitter 100 through the receiving antenna and the output of the receiving unit 201 are outside the receiving range of the transmission signal emitted from the remote control transmitter 100. If it is impossible to receive the encryption code at the position, the encryption code comparison unit 202 which generates an active output in comparison with the encryption code set by the encryption code setting unit 202A is connected to the output of the encryption code comparison unit 202, The output of the high voltage side power control unit 205 (or / alarm side power control unit 207) for controlling the power of the power supply unit 204 provided to the high voltage generation means 206 (or / alarm means 207) It consists of the structure containing the delay part 203 etc. which make time delay.

In addition, the delay unit 203 is composed of a timer circuit for delaying and outputting the active output of the encryption code comparison unit 202 for a predetermined time, and the output of the high voltage generating means 206 is a high voltage power as in the conventional method. The extreme ends 2A and AB are connected to the positive electrode 3A and the negative electrode 3B of the first embodiment, respectively.

4 shows another embodiment of the present invention.

In this case, the receiver 201 receives a signal transmitted from the remote controller transmitter 100 through a reception antenna, and a position outside the reception range of the transmission signal emitted from the remote controller transmitter 100 following the output of the receiver 201. If it is impossible to receive the encryption code, the encryption code comparison unit 202 which generates an active output by comparing with the encryption code set by the encryption code setting unit 202A and the output of the encryption code comparison unit 202 A high voltage power control unit 205 (or / alarm power control unit 208) for controlling the power of the power supply unit 204 provided to the high voltage generating means 206 (or / alarm means 207), and control operation thereof. The system consisting of a delay unit 203 for delaying a predetermined time has a configuration substantially the same as that of FIG. 3, and the encryption code and the second encryption code setting unit 209A which are connected to another path of the receiving unit 201 are received. Snowy When the predetermined encryption code matches, the second encryption code comparison unit 209 which compares the generated encryption code to generate an active output, and the second control unit which is connected to the output of the delay unit 203 and controls the power supplied to the high voltage / alarm generating means. Automatic / manual switch 212 that selects a power control unit 210 or 211, a power control unit 205 or 207, and a second power control unit 210 or 211 as necessary to connect power from the power supply unit 204. Consists of a configuration including all.

In addition, the configuration of the receiver 201 in the system is shown in detail as shown in FIG.

Here, the normal tuning circuit by the transistors Q1 to Q3, the manual / automatic selection position 201a connected to the rear end of the tuning circuit, and the reception sensitivity adjusting variable resistor 201b connected to the automatic end are shown. It consists of a configuration including the back.

In addition, in the above system, the types of operating the high voltage generating means 205 and the alarm means 208 are described separately, but they may be configured to simultaneously use the high voltage and the alarm generation if necessary.

In this case, as shown in FIG. 3, the high voltage side power control unit 205 and the alarm side power control unit 207 may be connected to the output side of the delay unit 203. In FIG. The power control unit 205, 207, 210, and 211 of the tank may be configured.

In the present invention having the above configuration, the user can operate the remote control transmitter 100 in the automatic mode or the manual mode in the remote control transmitter 100 of FIG.

At this time, the automatic mode operates in the automatic mode when the automatic / manual switch 101A of the automatic / manual switch unit 101 of the remote controller transmitter 100 is connected to the automatic side.

In this automatic mode, a high voltage / alarm generating circuit 200 as shown in FIG. 3 is installed in a bag or the like, and when the bag is taken out by the bag, the bag can transmit a transmission reach (about several tens M) of the remote control transmitter 100 carried by the user. This mode is activated when it is exited.

That is, the RF FM modulated signal including the encryption code output from the remote control transmitter 100 carried by the user modulates the encryption code set by the code setting unit 103 to the modulation output unit 102 as in a normal operation. When the signal is transmitted to the antenna 105 through the signal amplifier 104, the transmission signal of the remote control transmitter 100 is received by the receiver 201 of the high voltage / alarm generation circuit 100 as shown in FIG. Predetermined signal is received through.

Then, this signal is appropriately amplified by the receiver 201 and provided to the encryption code comparator 202. The encryption code comparator 202 demodulates the input RF signal, and also the encryption code in the demodulated RF signal. Is read and compared with the encryption code set by the code setting section 202A.

The receiving unit 201 may use the system in the manual mode and the automatic mode by the manual / automatic selection switch 201 as shown in FIG. 5, and the manual mode is actively driven using the remote controller transmitter 100 as in the conventional art. In the automatic mode, when the input sensitivity is adjusted using the reception sensitivity control variable resistor 201b, the reception sensitivity distance can be adjusted from several m to several tens of meters.

If the code comparison result code of the encryption code 202 matches, the power control unit 205 or 207 is turned off so that the high or low pressure generating means 206 or the alarm means 208 is not operated.

However, when a criminal is caught and escapes with the bag 1, the user does not know and the user can use the RF receiving range centering on the remote control transmitter 100 (receiving sensitivity adjusting variable resistor 201b of FIG. 5). The sensitivity value will be out of the set distance value), and the reception unit 201 of the high voltage / alarm generation circuit 200 will rapidly reduce the level of the received signal so that the encryption code comparison unit 202 no longer receives the remote control transmitter 100. The encryption code is not decoded, and accordingly a high voltage generation (or alarm generation) operation signal is output as a result of comparison with the code set by the code setting unit 202A.

The high voltage generation (or alarm generation) operation signal turns on the power supply control unit 205 or 207, and when the power control unit 205 or 207 is turned on, the power supply of the power supply unit 204 is turned on by the high voltage generation means 206 or the alarm means 208. Is supplied.

At this time, when the output of the encryption code comparison unit 202 passes through the delay unit 203, which is a timer circuit, and is supplied to the power control unit 205 or 207 after a predetermined time delay, high voltage (or alarm) occurs due to user's carelessness. It will be able to secure a time allowance to correct the case where one is subjected to an electric shock.

The user carelessness as described above refers to a case in which the manual switch 101B is unexpectedly external force or when the user presses it in a state that the user manually releases the auto / manual switch 101A of the auto / manual selection switch unit 101. Can be mentioned.

The high voltage generator 206 supplied as described above generates a high voltage (approximately 40 KV to 90 KV, the current being a weak current) of a sufficient level necessary for electric shock as in the conventional method, and supplies the high voltage electrode unit 207 to the high voltage electrode unit 207. The criminal is subject to electric shock by the high voltage generated by the high voltage electrode unit 207.

Meanwhile, in another embodiment of the fourth embodiment, the user may use the automatic / manual switch 212 of the high voltage / alarm generation circuit 200A in an automatic or manual mode.

That is, in this case, when the user automatically sets the auto / manual switch 212 on the high voltage / alarm generation circuit 200A side, the same operation as in FIG. 3 is performed. The automatic / manual selection switch 101A of the automatic / manual switch unit 101 can be operated in the manual mode with the manual position.

At this time, when the user is mainly carrying a bag, when the criminal snatch the user is to enable the user to actively operate the high voltage / alarm generation circuit (200A).

In this case, when the criminal forcibly steals the user's carry bag, turning on the manual switch 101B of the remote control transmitter 100 outputs an RF FM signal carrying an encryption code through the remote control transmitter 100 as described above. .

The encryption code signal transmitted from the above is provided to the receiving unit 201 via the receiving antenna of the high voltage / alarm generating circuit 200A on the side of the criminal takeover bag located within the transmission reach of the remote control transmitter 100, which is again provided. The encryption code comparison unit 209 demodulates the received signal and compares the encryption data set by the second encryption code setting unit 209A with the received encryption code data.

When the encryption code data compared by the second encryption code comparison unit 209 matches, the second power supply control unit 210 or 211 is driven to connect the power from the power supply unit 204 to the high voltage generating means 206, The high voltage generating means 206 generates an electric shock electrode through the high voltage electrodes 2A and 2B so that the criminal is subjected to an electric shock as in the normal operation.

At this time, if the alarm means 208 is installed together, the alarm operation can be performed at the same time to ventilate the periphery of the criminal to help the third party according to the bag to be caught.

In addition, the power controllers 210 and 211 configure a switching circuit to be turned on / off by a toggle (TOGGLE) every time an operation signal is input from the encryption code comparison unit 209, and when the manual switch 101B of the remote control transmitter is pressed. Each time, high voltage operation, then high voltage operation stops, and high voltage operation.

The present invention as described above is capable of operating the system not only in the anti-theft state but also in the anti-theft state, which performs high voltage and alarm operation by wireless remote means when being snatched while carrying a bag or the like. In addition, since user careless actions can be taken, various operations and reliability of such a system can be secured.
