3 is a control flow diagram illustrating an operation state of a traffic light change alarm method using car-audio according to an embodiment of the present invention. As shown in FIG. 3, the first step S1 turns on the start of an unspecified vehicle. In the state where the vehicle enters within the sensor range of the traffic light, the signal of the traffic light is green and the signal generation is stopped in the encoder unit 20 of the traffic light, that is, no signal is input.

In addition, after performing the first step S1, the second step S2 determines whether the signal of the traffic light is before turning on the yellow light for converting from the green light to the red stop light. Perform a general traffic light operation, and if the yellow light is to be turned on to operate the encoder unit 20 of the traffic light.

In addition, after performing the second step S2, the third step S3 determines whether the RF receiver 60 of the car audio detects a signal transmitted from the control signal transmitter 10, such as a traffic light, and detects the detected signal. If so, the received signal is decoded by the code detector 70 and input to the car audio microcomputer 30.

In addition, after performing the third step S3, the fourth step S4 determines whether the decoder-generated data is the correct value in the car audio micom 130. If the correct value, the car-audio power is turned on. If not, turn on the power, and if it is on, the car-audio microcomputer 130 commands the volume unit 80 to listen. The sound being muted and a warning sound is generated through the speaker 100.

In addition, after performing the fourth step, the fifth step S5 determines whether the signal is changed from a red light to a green light after the vehicle stops at the stop line, and if it is not changed, stops until the signal is changed. If the brake is not in normal operation, the alarm sounds for a predetermined number of times.

In addition, in the sixth step S6, when the traffic light is changed to green in the fifth step S5, the operation of the control signal transmitter 10 is stopped by the encoder 20 of the traffic light, and the code detection unit of the car audio is performed. The car-audio micom 130 determines whether there is information input at 70, and if not, performs the third step (S3) again, and if there is input information, cancels the car audio and returns to the previous mode. It is supposed to perform.

Hereinafter, the operation of the traffic light change notification device and method using the above-described car audio will be described in more detail with reference to FIGS. 1, 2, and 3.

First, the vehicle enters within the sensing range of the traffic light system installed at the intersection while driving with an unspecified start of the vehicle. If the traffic light is green, the traffic light system Since the installed encoder 20 does not input any signal to the control signal transmitter 10 of the traffic light system, the control signal transmitter 10 is in a state in which signal generation is stopped (S1). In this case, when the control signal transmitter 10 transmits data to the car audio, an infrared light emitting diode is used.

However, when the vehicle enters the sensing range of the traffic light system, it is determined whether the green light of the traffic light is in a state before the yellow light for turning into a red stop light turns on, and if the yellow light is not turned on, the general traffic light operation is performed. In the state where the yellow light is to be turned on, the traffic light micom 40 operates the encoder unit 20 of the traffic light system (S2). In performing the above general traffic light operation, a police officer or a traffic controller may manually perform various operations for operating a traffic light through the key input unit 50.

Subsequently, after the encoder unit 20 of the traffic light system is operated, it is determined whether a signal transmitted from the control signal transmitter 10 of the traffic light system is detected through the RF receiver 60 of the car audio mounted in the vehicle. If the detected signal is detected by the code detector 70 to input to the car-audio microcomputer (130) (S3).

That is, when the data according to the traffic light state is input to the RF receiver 60 in the traffic light control system, the car-audio code detection unit 70 receives the decoder and inputs the decoder to the car-audio micom 130, thus the car audio micom. If no signal is input to 130, it means that no signal is input to the RF receiver 60.

After performing the third step S3, the car-audio micom 130 determines whether the decoder-generated data input from the code detector 70 is a correct value, and if not, the RF receiver 60 again. Decode the data received from the code detector 70, and if the correct value car-audio microcomputer 130 detects the power state of the car-audio.

At this time, if the power of the car audio is not turned on, the power is turned on, if the power of the car audio is turned on, the volume unit 80 is commanded to mute the audio volume currently being listened to. , Inputs a signal for outputting the warning sound to the warning sound output unit 140.

Thereafter, the power amplifier 90 amplifies the signal input from the warning sound output unit 140 and generates various message warning sounds for the traffic light switching state for a predetermined number of times through the car-audio speaker 100 (S4). At this time, the warning sound is released in the brake braking state of the vehicle.

Thereafter, after performing the fourth step S4, the signal lamp microcomputer 40 determines whether the signal displayed through the traffic light display unit 30 of the traffic light system is changed from red to green light, and the signal is not changed. If the vehicle stops until the signal is changed, a warning sound is generated for a predetermined number of times through the car-audio speaker 100 when the brake of the vehicle is not normal operation (S5). That is, when the car tries to start in a state where the traffic light is a red light, a warning sound sounds through the speaker 100 of the car audio.

Subsequently, if the signal is changed to green light, the control signal transmitter 10 of the traffic light system stops data transmission, and the car audio micom 130 checks whether there is data input through the RF receiver 60 of the car audio. If it is determined, the received data is input to the car audio micom 130, and if there is no received data, the mute state is released from the volume unit 80 of the car audio, and the mode returns to the previous mode (S6). .

Here, the previous mode is to perform a general car-audio operation such as receiving an FM broadcast transmitted from a broadcasting station through the FM tuner 110 or receiving an AM broadcast transmitted from a broadcasting station through the AM tuner 120. Say

In addition, the car-audio series as described above is displayed so that the driver or passenger can see through the display unit 150, and various operations may be performed manually through the key input unit 160. That is, the operation state of the traffic light can be manually operated through the key input unit 160 or can be stopped.

In addition, the operation state of the traffic light system also allows the police officer or traffic controller to see the state of the traffic light through the traffic light display unit 30, and can be manually adjusted various states such as the signal through the key input unit (50). That is, the time that the traffic light turns off can be manually adjusted through the key input unit 50.

Meanwhile, the present invention is not limited to the above embodiments and can be variously modified within the scope not departing from the technical gist of the present invention.

As described above, the apparatus and method for notifying a traffic light change using the car audio according to the present invention may use the car audio for a few seconds before the traffic light in front of a predetermined meter is changed by using a predetermined car audio mounted on an unspecified vehicle. By informing the driver of the changed state of the traffic light through the speaker mounted on the, there is an effect such that the driver can cope with the changed traffic light situation in advance.
