Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a radio apparatus for a situation information communication function for collecting information on traffic situations as well as various emergency situations occurring in the vehicle itself and automatically notifying the outside.

When the driving environment of a vehicle deteriorates due to various disasters such as a sudden crash of a driving vehicle and damage to its own vehicle as well as road breakage, the driver himself or herself has to repair or request a vehicle. However, in an emergency situation where it is difficult for the driver to cope, it was practically difficult to directly respond or request a rescue. Furthermore, the driver of the succeeding vehicle that did not recognize the accident situation of the preceding vehicle could not stop quickly in the sudden stop of the preceding vehicle, and could cause a collision or collision between the vehicles. However, a chain collision or a collision could lead to a major accident, causing a lot of personal injury and property damage, causing traffic congestion and congestion.

On the other hand, since the driver has to concentrate his / her line of sight while driving, it is not preferable to view a video image or the like capable of dispersing the line of sight. Therefore, most drivers listen to listening radio and music to get energized during driving, which can be somewhat boring or drowsy.

However, since frequency management for radio broadcasting is managed by placing different transmission stations for each region, and a transmitting station transmits different frequency bands for the same broadcasting, when the driver enters a frequency effective range of another transmitting station and receives broadcasts of different frequency bands The sound quality of the broadcast we are currently listening to has dropped significantly. As a result, the driver directly manipulated the tuner of the radio to match the channel to the transmission frequency of the transmitting station, thereby improving the sound quality of the same broadcast being output.

However, this frequency adjustment method has the inconvenience that the driver has to manually adjust the channel manually, and in this process, the driver could not concentrate on the driving, and there was a risk of causing a car accident.

For reference, the communication signal in the emergency frequency band is transmitted through the transmitting antenna (A) of the FMT module (170). On the other hand, the emergency frequency transmitted from the FMT module 170 causes the control module 180 to include specific information on an emergency situation, and the control module 180 of the radio device transmits the emergency frequency to the other vehicle Information can be confirmed and specific contents can be outputted through the audio device of the vehicle or the terminal such as the smartphone of the driver. In addition, the control module 180 of the radio apparatus outputs to the other vehicle receiving the emergency frequency only the emergency frequency that does not include the specific information, and outputs the information set for the emergency even if the receiving frequency band is the emergency frequency can do. For reference, the emergency frequency transmitted from the FMT module 170 may include at least one selected from the vehicle number, the vehicle type, the identification number, and the vehicle attention ID of the installed vehicle.

The control module 180 changes the transmission frequency of the FMT module 170 to a broadcasting frequency band that is an airwave frequency band to transmit a communication signal and changes the frequency of the broadcasting frequency band to an interval designated to be sequentially transmitted, do. As described above, the control module 180 controls the booster of the FMT module 170 to increase the output strength of the communication signal when the communication signal for the emergency situation is transmitted, adjusts the calling frequency to a plurality of airwave frequency bands . Therefore, a vehicle that listens to the radio of a specific broadcast among neighboring vehicles can receive the communication signal in the airwave frequency band of the broadcast. For reference, since the broadcast frequency is the airwave radio frequency, the control module 180 of the originating vehicle transmits specific information about the emergency situation to the broadcast frequency. Therefore, the other vehicle receiving the broadcast frequency can receive the specific information, and the driver can recognize the emergency situation.

The communication signal is transmitted to the audio device 200 or the smartphone 300 of the vehicle driver through the output module 160 or the FMT module 170 and the smartphone 300 transmits the communication signal Upon receipt, it performs a designated call according to a set process, such as a public network or Internet call, SMS, or MMS.

The emergency presence check step S40 'includes a position checking step S41, a traveling state checking step S42, and an emergency situation determining step S43.

S41; Locations Step

The control module 180 searches the data module 110 based on the GPS information received from the GPS module 120 and confirms the dangerous section position information corresponding to the position of the GPS information.

The data module 110 stores the map information, and the control module 180 searches the map information based on the GPS information confirmed at the current position to search for the point where the vehicle is currently located.

S42; Checking the driving condition

The control module 180 calculates the rate of change of the GPS information with respect to time to confirm the speed of the traveling vehicle. In addition, in a region where reception of GPS information is difficult, such as a tunnel, the length information of the corresponding tunnel stored in the data module 110 and the vehicle speed immediately before the entry are calculated, and the expected time for the vehicle to come out from the tunnel is confirmed. Here, the time point at which the vehicle comes out of the tunnel is the point at which the GPS module 120 receives GPS information subsequently.

S43; Emergency decision step

The control module 180 searches the data module 110 based on the GPS information and confirms whether the corresponding location is classified as a dangerous section such as a tunnel, a bridge, an overpass, a mountainous region, or the like.

If it is confirmed that the speed of the traveling vehicle is lower than the reference value, it is determined that the speed is lower than the reference value.

In this embodiment, when the speed of the traveling vehicle in the danger zone is less than the reference value, it is considered that there is a traffic jam. In addition, when the speed of the driving vehicle suddenly stops and stops, it is regarded as an accident occurrence. In addition, when the detection signal of the sensor module 150 is confirmed and designated information such as high temperature and high sound is received, it is assumed that an emergency situation has occurred in the vehicle.

S31; Emergency Frequency Confirmation Step

The frequency check module 140 checks the frequency bands received by the tuner module 130 to determine whether the frequencies include the emergency frequencies.

If the emergency frequency is identified among the frequencies, the emergency state confirmation step S40 is performed.

S32; Frequency reception sensitivity check step

The frequency check module 140 checks the reception sensitivity of the selected channel frequency in real time to check whether the frequency of the currently selected channel is below the reference value.

S33; Transmitter information confirmation step

The control module 180 checks the current position of the vehicle based on the GPS information received from the GPS module 120, and transmits the transmission site information in which the current position is set as the effective period of the transmission frequency and the frequency information of the broadcast 0.0 > 110 < / RTI >

When the frequency reception sensitivity of the currently selected broadcast becomes smaller than the reference value, the control module 180 transmits the transmitter information for transmitting the broadcast frequency equal to the frequency of the selected channel to the data module 110, .

S34; Frequency change step

The tuner module 130 automatically changes the frequency band corresponding to the broadcast of the currently selected channel among the frequency bands in which the reception sensitivity is valid at the current position to the frequency of the selected channel so that the radio apparatus 100 continuously broadcasts the same broadcast Output continuously.
