[0005] BACKGROUND
[0006] In order to prevent the loss of life in traffic accidents, it is necessary to intervene early. In the event that the persons involved in the accident lose consciousness or do not have access to communication tools, the intervention teams may be aware of the accident by informing the intervention teams of those who see the accident in the vicinity. All these methods of calling for help include the human factor and cause the victims to be late in the intervention when a person who can call for help is not present.
[0007] In the state of the art, which operates in the visible light spectrum, systems are known that transmit accident information through communication between a receiver mounted on a streetlight and a transmitter mounted on a vehicle. Due to the fact that the signal emitter on the vehicle is not in the same direction as the signal receiver in the streetlight, data transmission cannot be provided or data loss may occur during data transmission. In this case, for the system used to operate, the signal emitter on the vehicle and the signal receiver on the streetlight must be in the same direction. This may not always be possible.

[0029] DETAILED DESCRIPTION OF THE INVENTION
[0030] In this detailed description, the subject matter of the invention is explained only by means of examples that will not have any limiting effect for a better understanding of the subject matter.
[0031] Referring to Figure 1 , the invention relates to an accident notification signal transmission system (1) for transmitting, in the event of an accident of a vehicle (10), accident notification data generated for an accident detected by at least one sensor on the vehicle (10) to a ground station (20).
[0032] The accident notification signal transmission system (1) referred to in Figure 1 provides for transmitting the accident notification signal from the vehicle (10) to the ground station (20) at least at a linear angle. Thus, it can be ensured that the accident notification signal is transmitted correctly and quickly to the control centers. The ground station (20) may comprise a ground lighting element provided for lighting purposes. The floor lighting element can be an incandescent / halogen / LED and similar model lamp. It is preferred to use a streetlight as the ground station (20) mentioned in a possible embodiment of the invention. However, the ground station (20) is not limited to streetlights. Any object located on the side of the road can be defined as the ground station (20).
[0033] There is a ground station receiver unit (21 ) provided on the ground station (20) referring to Figure 1. The said ground station receiver unit (21) provides for receiving the accident notification signal sent over the vehicle (10). The ground station receiver unit (21) enables the accident notification signal received over the vehicle (10) to be transmitted to a control center. The ground station receiver unit (21 ) is used as a customized photodetector, etc. to receive the accident information data transmitted from the vehicle (10).
[0034] Referring to Figure 1 , the accident notification signal transmission system (1) comprises a vehicle transmitter unit (11) arranged on the vehicle (10) for transmitting the accident information received from the vehicle (10) to the ground station receiver unit (21) in the event of an accident of a vehicle (10). The vehicle transmitter unit (11) is located around the vehicle's headlights in a possible embodiment of the invention. The vehicle transmitter unit (11 ) comprises a plurality of LEDs arranged in multiple rows sufficiently parallel to each other to transmit the accident information data. The said LEDs can operate in an invisible light domain customized for data transmission. In an alternative embodiment of the invention, the said LEDs can operate in a customized visible light domain for data transmission. There is at least one drive mechanism (111 ) to enable the vehicle transmitter unit (11 ) to be directed to the ground station receiver unit (21) in a possible embodiment of the invention. It is preferred to use a servo motor etc. as the drive mechanism (111) mentioned in a possible embodiment of the invention. There is a processor unit provided to the vehicle (10) to control the movement of the said drive mechanism (111 ). The ground station receiver unit (21) enables the accident information data to be received from the vehicle transmitter unit (11).
[0035] There is a signal emitter (22) arranged in the ground station (20) referring to Figure 1 . The signal emitter (22) is provided to emit an invisible light at a wavelength of 1550 nm. As a result of the light being transmitted at 1550 nm wavelength, the effects of daylight are reduced to a minimum. This increases the quality of the transmitted light. In addition, it can be used at night, during the day, indoors, and outdoors, harmless to human health. The signal emitter (22) is provided in another possible embodiment of the invention to emit visible light at a value between 360 and 700 nm wavelength. The signal emitter (22) is disposed of on a plate provided in a semi-spherical form disposed on the ground station (20). The signal emitter (22) comprises a plurality of IR LEDs emitting light at different angles arranged on a plate provided in the said semi-spherical form. The fact that IR LEDs are placed on the plate provided in semi-spherical form ensures that the lights are spread in all directions at different angles.
[0036] There is a signal receiver (12) for receiving at least one of the lights emitted by the signal emitter (22) arranged on the vehicle (10) referring to Figure 1 . The said signal receiver (12) is used as a customized photodetector, etc. to receive light. A photodetector with a 1550 nm centered frequency response provided for receiving light as the signal receiver (12) is used in a possible embodiment of the invention. A photodetector with an intermittent frequency response of 360-700 nm is used to receive light as the signal receiver (12) in an alternative embodiment of the invention. There is at least one drive unit (122) that is operated to enable the signal receiver (12) to be directed to the signal emitter (22). The drive unit (122) comprises a first drive element (1221) for changing the position of the signal receiver (12) in a first direction. It is preferred to use a servo motor etc. as the said first drive element (1221) in a possible embodiment of the invention. In an alternative embodiment of the invention, it is preferred to use at least one electric motor as the first drive element (1221). In an alternative embodiment of the invention, it is preferred to use at least one motor as the first drive element (1221 ). The drive unit (122) comprises a second drive element (1222) for changing the position of the signal receiver (12) in a second direction. It is preferred to use a servo motor etc. as the said second drive element (1222) in a possible embodiment of the invention. In an alternative embodiment of the invention, it is preferred to use at least one electric motor as the second drive element (1222). In an alternative embodiment of the invention, it is preferred to use at least one motor as the second drive element (1222).
[0037] Referring to Figure 2, there is a control unit (121) for controlling the operation of the drive unit (122). The control unit (121) also controls the actuation of the drive unit (122), allowing the light emitted from the light emitter to be analyzed. The control unit (121) may also comprise a processor and a memory (ROM, RAM, PROM, EPROM, EEPROM) associated with the said processor, which may provide permanent, temporary storage of the data, in a possible embodiment of the invention. The control unit (121) is configured to enable performing the processing steps pre-recorded to the memory by the processor in a possible embodiment of the invention. Referring to Figure 2, the control unit (121) is configured to provide location information by enabling the drive unit (122) to be actuated to enable the signal receiver (12) to receive the light emitted by the signal emitter (22) in at least a linear plane. The location information comprises angle and direction information to enable the light emitted from the signal emitter (22) to be received by the signal receiver (12) at least in a linear plane.
[0038] Referring to Figure 2, the control unit (121) enables the first drive element (1221) and the second drive element (1222) to be actuated, thereby directing the signal receiver (12) to the signal emitter (22). The light emitted by the signal emitter (22) is thus provided to be received at least in a partially linear plane by the signal receiver (12). The control unit (121) enables the position information comprising the angle and direction information of the said linear plane to be transmitted to the vehicle transmitter unit (11). The control unit (121 ) is associated with the processor unit (112) provided to the vehicle transmitter unit (11). The processor unit (112) enables the drive mechanism (111) to be operated according to the location information received from the control unit (121 ). In this case, the angle between the vehicle transmitter unit (11 ) and the ground station receiver unit (21) is adjusted, allowing the accident information data to be transmitted in at least a partially linear plane. This ensures that the data is transmitted reliably and quickly.
[0039] An exemplary operating scenario of the invention is described as follows:
[0040] At least one accident sensor is provided in the vehicle (10). As is known in the art, the accident sensor generates a signal according to factors such as the severity of the collision, the number of damaged parts and the amount of damage, etc., in case of an accident of the vehicle (10). Accident sensors are not detailed here as they are well-known in the art. In the event of an accident with the vehicle (10), an accident notification signal is provided by a vehicle processor according to the data received from the said accident sensor provided on the vehicle (10). The accident notification signal may include passenger information such as the number of passengers, passenger ages, passenger health status, etc., and information such as the provided identification number specific to the vehicle (10), the severity of the accident, additional information of the vehicle (10), etc. The accident notification signal is transmitted to the vehicle transmitter unit (11 ). The light is continuously emitted from the signal emitter (22) provided to the ground station (20). The control unit (121 ) allows the direction of the signal receiver (12) to be changed in order to scan the light emitted by the signal emitter (22). The control unit (121 ) allows the signals received from the signal emitter (22) to be processed by an algorithm. It is preferred to use the weighted average algorithm as the aforementioned algorithm. The aforementioned weighted average algorithm allows scanning and finding the maximum power in the plane to find the direct angle of view. The control unit (121 ) provides for operating at least one of the first drive elements (1221 ) and the second drive element (1222) to ensure that the signal received by the signal sensor is received at least linearly. As a result of each operation of the first drive element (1221) and the second drive element (1222), the algorithm recalculates and allows the calculation of a linear signal transmission path. The control unit (121) provides for generating position data if the first drive element (1221 ) and the second drive element (1222) detect that the signal received from the signal emitter (22) is received at least linearly. The location information comprises angle and direction information that enables the light emitted from the signal emitter (22) to be received by the signal receiver (12) in the closest direction to the linear plane. The control unit (121) enables the location information to be transmitted to the processor unit (112) of the vehicle transmitter unit (11). The processor unit (112) enables the drive mechanism (111 ) to be operated according to the location information, enabling the vehicle transmitter unit (11) to be directed to the ground station receiver unit (21). Thus, it is ensured that the accident notification signal is transmitted at a linear and / or partially linear angle. Transmitting a signal at a linear angle allows the transmission of information safely while increasing the transmission speed of the signal.
[0041] It is ensured that an accident notification signal is created by an accident of a vehicle (10) in an exemplary embodiment of the invention. It is ensured that the LEDs are directed to the receiver in the streetlight to ensure that the accident notification signal is transmitted to the photodetector on the streetlight through the LEDs provided to the headlights. A light signal is emitted from the IR LEDs provided to the streetlight. It is ensured that the lights emitted from the IR LEDs are scanned by means of the photodetector placed on the vehicle (10). The control unit (121 ) provides for the operation of servo motors that enable the photodetector to move to enable the photodetector to be received with the linear viewing angle of the light received from the IR LEDs. The control unit (121 ) enables the pre-recorded weight average algorithm to be run on the memory via the processor. The processor controls the operation of the first servo motor to enable the movement of the photodetector in the x plane according to the weighted average algorithm, and the second servo motor to enable the movement of the photodetector in the y plane.
[0042] According to an exemplary working scenario of the algorithm, the second servo motor is kept constant at 90 degrees. Here, the first servo motor is moved 180 degrees while the second servo is at the first angle value in the y plane. Thus, the highest first power in this plane can be found. If the maximum number of powers in the same plane is more than one, the median of the locations where the maximum powers are located is taken. It is then ensured that the second servo motor is kept constant at 180 degrees. Here, the first servo motor is moved 180 degrees while the second servo is at the second angle in the y plane. Thus, the second highest power in this plane can be found. If the maximum number of powers in the same plane is more than one, the median of the locations where the maximum powers are located is taken. Then, the first power and the second power value are compared. As a result of the comparison, a first angle value is calculated if the second power value is greater than the first power value. As a result of the comparison, if the second power value is smaller than the first power value, a second angle value is calculated. While the first servo motor is at least one of the first angle values or the second angle value, the second servo motor is moved from 0 degrees to 180 degrees. This results in maximum power. If this maximum power value is greater than the first power value and the second power value, the algorithm is terminated. If this maximum power value is less than the first power value and the second power value, the algorithm is terminated, and the location of the larger power value is taken. The control unit (121 ) allows these operations to be repeated until the direct viewing angle is determined. Thanks to this algorithm, the Y plane is scanned from 90 degrees to 180 degrees. Instead of scanning for each Y value one by one, the scanning time is reduced by using the weighted average algorithm. In addition, the use of a large number of loops increases the possibility of the last location being a direct viewing angle. The control unit (121 ) enables the first servo motor and the second servo motor to be brought to the angle position directly with respect to the IR LEDs by the weight medium algorithm. If the processor detects that the light received from the IR LEDs is a direct viewing angle or an angle partially close to the said direct viewing angle, it ensures that position information containing the said angle and direction information is transmitted to the processor unit (112) that controls the movement of the transmitter LEDs in the headlights. The processor unit (112) ensures that the servo motors that enable the movement of the LEDs are operated according to the location information. The LEDs are positioned in the same direction as the photodetector on the streetlight in a partially linear angle position. The accident notification signal is transmitted to the photodetector in the streetlight by bringing the LEDs to the linear angle position.
[0043] The accident notification signal transmission system (1) can be used not only in accident notification but also in all systems with a similar purpose. For example, it is provided that it can be integrated into each system using the structure of transferring data with a direct viewing angle. The protection scope of the invention is specified in the appended claims and certainly cannot be limited to what has been described in this detailed description for illustrative purposes. It is clear that those skilled in the art can produce similar embodiments in the light of the foregoing without departing from the main theme of the invention.
