In order to achieve the above another object, the method of the present invention comprises the steps of introducing a remote control signal in the initial state, comparing the password of the incoming remote control signal with the built-in password in the system control unit in the stereo, and the password At the same time, if the key output from the remote controller is on, detecting the signal output from the sensing sensor unit, and detecting the signal output from the sensing sensor unit, if the "H" state, the control signal and the alarm pulse are activated. It outputs the alarm to sound, and the user through the alarm sound transmitting and receiving unit to hear the alarm sound, characterized in that it comprises a process of repeating the above process.

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

1 is a block diagram showing an embodiment of a car stereo device having a remote burglar alarm system according to the present invention. Looking at the configuration of the car stereo body, a tuner is coupled to a preamplifier, and the output signal of the preamplifier is a system. It is input to the control unit and the output of the password setting unit and the sensor unit is also input to the system control unit. One end of the output of the system control unit is connected to the alarm sound transmitter and the other end of the switch SW1. One end of the switch is coupled to an output stage coupled to an alarm sound transmitter of an output stage of the system control unit, and the other end is coupled to a voice amplifier. The negative amplifier is coupled to an external speaker.

Next, looking at the configuration of the portable remote control set, the key operation unit is coupled to the microcomputer, the output of the encryption quality unit is input to the remote control unit, the output of the remote control unit is input to the data transmitter.

Looking at the operation according to the configuration, when the user is away, press the on key of the portable remote control set and carry the remote control set. In this case, the tuner of the car stereo unit picks up the transmission signal of the remote controller on the set specific channel and outputs it to the preamplifier. Here, the channel for receiving the remote control signal is set in advance by selecting one of the channels not used in the radio. The preamplifier amplifies the weak signal output from the tuner 10 to the required signal and also corrects the frequency characteristic so that the original sound comes from the speaker. The signal output from the preamplifier 30 is input to the system control unit 60. At this time, the system control unit has a built-in password by the encryption setting unit 40, that is, a dual in line package (DIP) switch. The system controller compares the password on the remote control signal received from the remote controller with the password embedded in the system controller to operate the original language signal when the password is the same. That is, when an on key is input, the system controller starts an operation on the on key when the password displayed on the on signal is the same as the internal password of the system controller.

After a slight time delay (30 seconds), the detection sensor unit 50 detects the output signal and determines that there is an intruder near the stereo when "H", and outputs an enable signal to the output of the system controller. Send alarm pulse. Here, the sensor unit detects an access object using an infrared sensor set to detect an object within a certain distance of the car stereo, and inputs the detected output to the system controller. The enable signal output from the system controller allows the alarm pulse to transmit the alarm sound out through the voice amplifier. In this case, the voice amplifier plays a role of power amplification so that a sufficient volume comes out. The alarm pulse is also input to the alarm sound transmitter 70, which can be heard only in the vicinity of the alarm sound output through the external speaker so that the user can hear the alarm sound through the remote control carried by the user using the alarm sound transmission report. For sake. The alarm pulse input to the alarm sound transmitter 70 is converted into an alarm control signal and then transmitted. At this time, the alarm sound reception and alarm unit generates an alarm sound for the control signal. If you press the off key on the remote control, all alarms will stop.

Since the car stereo device equipped with the remote burglar alarm system of FIG. 1 described above can use any channel by radio propagation, remote control reception is achieved by using the existing car stereo tuner as it is.

Next, referring to FIG. 2, the burglar alarm method according to the present invention is divided into the following processes.

a. The process of injecting the remote control signal from the initial state

b. Comparing the password of the remote controller signal with the password embedded in the system control unit in the stereo.

c. Detecting a signal output from the detection sensor unit when the key output from the remote controller is on when the password is the same.

d. Detects the signal output from the detection sensor unit, and outputs an alarm pulse to the control signal so that the alarm sound is activated when the "H" signal is activated, and the user can hear the alarm sound through the alarm sound transmission and reception unit. To repeat the above procedure.

Looking at the step-by-step process, the system control unit, which is an alarm sound control means of the internal car system, clears the ram in the system initialization state (step 120), and sets the initial value (step 121). If it is determined (step 122), if it is input, the detected password is compared with the password built in the system controller (step 123), and if it is not input, it proceeds to step 122. In step 123, if the passwords are the same, go to the next step, and if not, jump to step 122. In step 124, if it is determined whether the input key is the on key (step 124), and if it is determined that the key is the on key (step 125), the dial tone is output once (step 126), and the input key is the on key If not, it determines that it is an off key (step 133) and outputs two beeps (step 134) and outputs a disable control signal so as not to sound an alarm (step 135). (Step 136) Jump to step 122. In step 127, if a predetermined time (30 seconds) has elapsed after the on-key is input, and if a predetermined time has elapsed, the output of the detection sensor unit is detected (step 128). In step 129, the enable control signal and the alarm pulse are output for the output sensor "H". In step 130, the alarm state is turned on. In step 131, the alarm state is detected or a predetermined time has elapsed. If a predetermined time has passed, the alarm state is turned off (step 132). Goes. After the alarm state is turned off, jump to step 122.

As described above, in the present invention, by installing the burglar alarm device in the car stereo, the burglar alarm can be performed without a separate device, and the alarm sound can be delivered to the user when an intruder is generated by using a portable remote control set.
