Description

Transmitting device for SOS using GPS in automobile}

The present invention relates to telematics, a wireless data service in which information is provided during the movement of a vehicle. More specifically, the present invention relates to telematics, which records a state of a vehicle or an accident and transmits the recorded data to enable rapid processing. A vehicle emergency rescue transmission apparatus.

With the recent development of the economy and the improvement of living standards, passenger cars are becoming more popular and the demand for them is exploding. As such, various traffic problems occur and traffic accidents occur frequently in proportion to the number of vehicles that are quantitatively exploding.

Traffic accidents are usually divided according to the negligence between the parties, the police authorities, and the insurance company, so the amount of damages is shared, and the cause of the accident is frequently disputed. have.

Therefore, it was required to develop a system to clearly and objectively identify the situation judgment accompanying a traffic accident, and it is now possible to store and use information on the driving status of a vehicle as in Patent Application No. 95-53855. The system has been developed and used.

However, the above black box system, despite the advantages of recording the situation at the time of the accident, has a fatal disadvantage that can not cope quickly with the accident was required to solve it.

On the other hand, Patent Application No. 96-28491 discloses a distress signal generating device for quickly detecting the distressed position to the other party by detecting the distressed position by using the GPS, and transmitting it with the distress signal.

However, the above-described conventional technique is to accurately identify the distress position by simply transmitting the distress occurrence by using the GPS receiver, and cannot take appropriate measures according to the accident situation, and the driver cannot send the rescue signal. There is a problem that becomes useless in the situation.

Therefore, the technical problem to be achieved by the present invention is to promptly process the accident by detecting the vehicle status or accident situation and the current position of the vehicle at the time of a vehicle accident, and to process and transmit the stored vehicle abnormality information and vehicle behavior information. It is to provide a vehicle emergency rescue device using a GPS.

In the vehicular emergency rescue transmission apparatus using GPS according to the present invention as described above, it is preferable to further include an emergency rescue signal generation unit for sending a distress signal is connected to the control unit.

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

1 is a block diagram of a vehicle emergency rescue transmission apparatus using GPS according to the present invention.

According to the above drawings, the present invention provides a driving information detecting unit 10 for detecting driving information of a vehicle, a position detecting unit 11 for detecting a current vehicle position by receiving a signal transmitted from a satellite, and a driving information detecting unit. The control unit 12 and the control unit 12 for determining whether the vehicle is abnormal by calculating a signal detected from the unit 10 and outputting the vehicle abnormality together with the current vehicle position detected by the position detector 11. It comprises a transmission and reception unit 13 for transmitting the signal, and the emergency rescue signal generator 14 connected to the control unit 12 for generating a false signal.

The driving information detection unit 10 detects the speed and acceleration of the vehicle and inputs the control unit 12 to the brake unit state detection means for detecting an operating state of the speed sensor, the acceleration sensor, the hand brake or the foot brake, And fuel state detection means and a water temperature sensor.

The driving information detector 10 obtains data from various sensors of the vehicle and applies the data to the control unit 12 to provide information about a vehicle accident and a vehicle abnormality.

The position detector 11 includes a GPS receiver (Global Positioning System).

As is well known, GPS uses satellites to make 3D positioning of longitude, latitude and altitude anywhere in the world. The system can be measured in real time, and the system can be used to measure the absolute direction and absolute speed.

The GPS receiver receives the GPS signal from the satellite and detects the current position. During non-receiving, the GPS receiver refers to the vehicle speed and brake information applied to the control unit 12 and the distance traveled from the last received point by referring to the signal of the acceleration sensor. The current position is corrected by detecting and direction.

The control unit 12 includes a ROM for storing programs and initial data, and a memory including FLASHROM and RAM for storing information to be stored while driving and basic information of the vehicle / driver, storing received information, and setting information. .

Accordingly, the control unit 12 compares the data stored in the ROM with the data stored in the ROM to determine whether the current vehicle is in an accident state or an emergency resulting from the operation of the emergency rescue switch 14 according to various data applied from the driving information detection unit 10. The control unit 13 is operated.

The transceiver 13 includes a wireless communication terminal or a mobile phone, an interface for transmitting and receiving data with a remote server, and a hands-free kit for operating the mobile phone according to a signal of the control unit 12 on which the mobile phone is mounted. A microphone / speaker signal processor for controlling amplification volume of the output signal of the microphone and the speaker connected to the hands-free may be included.

On the other hand, the emergency rescue signal generation unit 14 is for coping with emergency situations such as vehicle strength or kidnapping and is installed in the interior of the vehicle and the trunk and includes a switch for applying a signal to the control unit 12. In response to the on signal of the switch, the control unit 12 controls the transmission and reception unit 13 to send an emergency rescue signal to the corresponding engine.

In the apparatus according to the present invention as described above, the control unit 12 sets the system time setting and the position information in the memory by analyzing the position information and the time information output from the GPS receiver, and the position information continuously corrected is periodically It is stored in memory and used as vehicle location information when transmitting information by communication. At this time, the main server communicating with the device can be used as additional information by grasping information such as the location, speed, brake operation status, airbag operation status of the vehicle.

In addition, when the vehicle signal is determined to be in an abnormal state, the control unit 12 transmits the vehicle information along with the current position and time data of the vehicle already input through the GPS receiver to the remote main server through the transceiver 13. Will be sent. At this time, the vehicle information is compressed into a form that can be transmitted. The packet is compressed by compressing information of the accident time, the detected impact amount, the braking distance, the road friction coefficient, the detected engine throttle opening amount, and the detected brake operation state. After creating the, each data will be sent to the remote main server.

In the present invention, the accident determination is made through the acceleration sensor of the detection unit 10, the acceleration sensor detects the vehicle acceleration signal, passes through the filter stage, periodically stores it in a memory, and calculates impact energy when a collision occurs. Therefore, when the energy value exceeds the reference value set in the memory or when the airbag is connected to the vehicle, it is determined as a vehicle accident.

In addition, it is determined whether the emergency rescue switch 14 installed in the vehicle is on or off, and when the switch 14 is turned on, the emergency occurrence signal and the corresponding information and the location / time data of the vehicle are transmitted to the main server.
