Technical Field

[1] The present invention relates to a system for detecting signals based on vehicle states and times at which an amount of impact is counted and a processing method thereof. Background Art

[2] Unexpected accident dangers have been increased in modern society due to a variety of cultures, driving habits and increase in vehicle, so that there is actually no system or processing method which can effectively notify a traffic accident or link to local police station and automatically notify the local police station of the traffic accident to process the accident in a fast and fair way when the traffic accident happens due to the negligence of the driver or an external factor while driving the vehicle or after parking the vehicle.

[3] This drawback may make it more difficult to determine the accident situation when a boundary between a wrongdoer and a victim is ambiguous and a witness or an accident scene is not preserved. Accordingly, it is required to check whether the corresponding vehicle is the wrongdoer and the damage situation in real time to thereby carry out on- the-spot inspection and accident processing in a fast and fair way when it is difficult to preserve the traffic accident scene due to the situation or personal injury accident or property damage accident happens due to the vehicle including a getaway vehicle. This would advance the modern society, however, there is no proper approach for the same.

[4] In particular, when there is no witness on the hit-and-run accident, it is not easy to find the criminal vehicle, there are a number of situations that make it more difficult to inspect the suspected vehicle due to destroyed or hidden evidences, inspection becomes more difficult to determine and find the wrongdoer due to fake alibi or perjury, and various unsettled cases are stacked to consume human resources and time on the traffic accident, so that it is desperately required to process the traffic accident in real time and handle the post-process with respect to the hit-and-run accidents that has no witness.

[11] FIG. 3 is a reference flowchart illustrating a system for detecting signals according to the present invention. Best Mode for Carrying Out the Invention

[12] FIG. 1 is a system block diagram for signal detection and processing thereof according to the present invention. As shown in FIG. 1, signals are processed between a vehicle and a control center in the present invention, and a pair of sensors for sensing an impact is disposed on front and back bumpers of a vehicle, which may be additionally disposed on a side and an upper plane of a glass for more sensitive and various processing.

[13] The system includes: a pair of sensors 13 disposed at an outside of the vehicle; a microcomputer 10 allowing the sensor 13 to generate a signal for which an amount of impact is counted and receiving the signal when the impact is real-time monitored and the amount of the impact exceeding a predetermined value is sensored by the sensors 13; a global positioning system (GPS) device 12 disposed for transmitting a current coordinate value and an impact occurrence time to the microcomputer 10 that has received the signal from the sensors 13; a storage 14 disposed to code the signal, the coordinate value and the time to be stored by the microcomputer; a power supply 11 for supplying a power to the microcomputer 10 and other additional devices; a communication interfacing device 15 disposed for communicating a coded information signal generated from the microcomputer 10 using wireless communication; and a control center 20, wherein the control center comprises: a communication interfacing device 25 disposed for receiving the coded information signal transmitted from the vehicle; a database (DB) 21 for writing and storing a coordinate value, a time and impact occurrence information of the coded information signal that is digitized and received by the control center 20; a relay station (switching network) 23 for primarily transmitting data analyzed through the control center 20 to local authorities; local competent centers 24a to 24n for receiving the coordinate value of the input coded information signal analyzed by the relay station 23 and transmitted to a local area; and scene management unit for real-time collecting real-time processed results or post- processed results about an accident and storing the real-time processed results or the post-processed results in the DB 21 when the real-time processed results or the post- processed results are finished by the local competent centers 24a to 24n.

[14] The storage 14 has a black box that does not allow edition and deletion and allows overwriting or reading to set a level of security or give a priority so that only an authorized person can access.

[15] The communication interfacing device 15 of the vehicle includes an oscillating unit

(OSC) for generating a carrier wave that is an electrically oscillating signal of a radio frequency required for transmission, amplifies the carrier wave generated from the OSC to a proper magnitude by an amplifier, mixes the coded signal transmitted from the vehicle using a modulator and transmits the radio frequency through an RF transmitter, and the communication interfacing device 25 of the control center receives the radio frequency including the coded information signal transmitted from the vehicle through an RF receiver, digitizes the received signal using a demodulator and transmits the digitized signal to the control center 20.

[16] The coded information signal includes an impact position, an amount of impact, and a vehicle state at the time of impact.

[17] In addition, the control center 20 may be the national police agency, the ministry of construction and transportation, the automobile insurance association, or the vehicle manufacturing company.

[19] The power supply 11 may be used as the power supply of the battery mounted on the vehicle engine room, however, it is preferable to design the power supply such that the power supply of the battery is blocked after start-up is turned off while the start-up key is at a lock position.

[20] This serves to prevent the battery from being discharged, and a substantially equivalent design range may be achieved for designing the power supply 11 of the present invention when the power supply of the battery is directly connected for sensing a damage of the parked vehicle, which is merely illustrative. Therefore, the sensors 13 of the present invention sense the amount of external physical impact to carry out the procedure of FIG. 1, so that accident records about the vehicle damage or stopped vehicle can be advantageously secured.

[21] As such, a method of processing a system that can determine whether an accident happens using a signal generated from a vehicle and activate real time mobilization is provided, and the method includes: a step Sl of initiating a power supply 11 for driving; a step S2 of turning on an impact detecting sensor to operate the impact sensing sensor due to a power supplied from the power supply 11; a step S3 of sensing the impact from a sensor detection operation of the sensor 13; a step S4 of checking a state with respect to the detected impact; a step of generating a wrongdoer signal S5 and a victim signal S6 from a microcomputer through the step S4; a step S7 of inputting a coordinate value including a sensor detection time through a global positioning system (GPS) 12 and a vehicle registration number to the signal information generated from the signal generation step; a step S 8 of modulating an input coded information signal to be transmitted to a control center 20; a step S9 of demodulating the signal from a communication interfacing device 25 to a digitized and coded information signal through the step S8, and storing the digitized and coded information signal in a database (DB) 21; a step SlO of checking state values of the coded information signals, and classifying generation regions to divide regions into real time processing types and post-processing types; a step Sl 1 of informing a local competent center for asking a corresponding local competent police station or local authority to support depending on the generation regions classified by the step SlO; a step S 12 of activating on-the-spot mobilization when the real time processing is required; a step S 13 of informing the local competent center or a control center S9 of the processed result by means of report or wireless communication after finishing the processing in the scene; and a step S 14 of receiving the report on a scene management unit 22 of the control center 20 by means of the step S 13 and updating information in the DB 21.

[22] The steps S5 and S6 from the step S4 may consider the cases that the generated signal corresponds to the stop position (P or N) of the gearshift or the engine is not overheated as an external impact to branch into the step S6, and consider the cases that the gearshift is at a drive position (D or R), the engine is overheated, the speedometer senses the speed, or RPM gauge measures the RPM exceeding the idle RPM as an accident occurrence while driving the vehicle to branch into the step S5.

[23] FIG. 3 is a reference flowchart illustrating a system for detecting signals according to the present invention, which determines the wrongdoer, the victim, and the negligence of the driver in the hit-and-run accident or the accident where the scene was not preserved, and another embodiment thereof will now be described.

[24] A method of processing a system that determines whether an accident happens and verifies the accident using a signal generated from a vehicle is provided, and the method includes: a step Al of initiating verification when a control center is informed of an accident; a step A3 of analyzing database DB of the control center for retrieving an accident scene position using a coordinate value, a corresponding registration number and unsettled accidents of a scene management unit 22 in order to search information matching the coordinate value of the accident scene and the estimated occurrence time of the accident; a step A6 of deriving similar attribute value from the DB using the step A3, the step of searching and checking the registration number and the step A5 of checking the unsettled cases; and a step A7 of analyzing the information detected by the step A6 and the coded information recorded in a storage 14 of an actual vehicle to check integrity.

[25] Preferred embodiments of the present invention have been disclosed herein and, although specific terms are employed, they are used and are to be interpreted in a generic and descriptive sense only and not for purpose of limitation. Accordingly, it will be understood by those of ordinary skill in the art that various changes in form and details may be made without departing from the spirit and scope of the present invention as set forth in the following claims.
