TR TR TR DESCRIPTION LASER WARNING SYSTEM Technical Field Invention; It is about a laser warning system that can be mounted on wearable equipment or a vehicle or a fixed structure and ensures the safety of drivers and pedestrians thanks to the warnings it gives. Known Status of the Technology Today, in parallel with the development of technology, various developments are taking place in the automotive industry. The most important of these developments is the introduction of vehicles using electric motors instead of vehicles using internal combustion engines. In addition to the advantages of the process in question, it has disadvantages that may arise from the quiet operation and fast travel of electric vehicles. While walking on streets and urban areas, one of the most important aids in deciding whether to cross a road is the sounds of approaching cars and car engines. For this reason, the increasing use of electric and autonomous vehicles and the quiet operation of these vehicles may cause accidents or safety vulnerabilities for pedestrians, cyclists or visually impaired people. In current technology, the use of laser marking, laser distance measuring and aerial vehicles is increasing. The only defense against these threats is laser detection and laser warning systems. Nowadays, there are systems that provide the ability to detect, detect and identify laser threats directed at them in a short response time and with high sensitivity, and to activate countermeasure systems, but these systems are expensive and have system integration problems, such as personnel carriers and combat vehicles, control stations, buildings and equipment. They cannot be used by other vehicles. The disadvantages of existing systems are that they are not cheap, lightweight, portable and easy to install. In addition, the high false alarm rate in laser warning systems is among the disadvantages of current state-of-the-art systems. In order to prevent errors and noise in the systems in question, special circuit and system designs must be made. Although this situation increases labor force and cost, it cannot reduce the false alarm rate to the desired levels. The invention with publication number U89448107BZ, which emerged as a result of technical research, relates to a method and apparatus used to detect laser in a laser excitation receiver. It is mentioned that in the mentioned apparatus, a panoramic lens assembly is combined with a laser detection focal plane and the laser light is refracted in the panoramic lens. In the invention in question, the refracted laser light is collected by a large number of sensors, the intensity corresponding to the laser light is determined, and then the combination of the panoramic lens and the laser detection focal plane is configured to provide a low-cost laser warning for ground-based situational awareness. As mentioned, the invention relates to a method and apparatus used to detect the laser in a laser stimulation receiver, and does not mention an embodiment that can provide a solution to the disadvantages mentioned above. As a result, due to the negativities described above and the inadequacy of existing solutions on the subject, it has become necessary to make a development in the relevant technical field. Purpose of the Invention: The invention aims to introduce a structure with different technical features that brings a new initiative in this field, unlike the structures used in the current technique, and to solve the drawbacks mentioned above. The primary purpose of the invention is; The aim is to introduce a laser warning system that can be mounted on wearable equipment or a vehicle or a fixed structure and ensures the safety of drivers and pedestrians thanks to the warnings it gives. Another purpose of the invention is; The aim of the proposed laser warning system is to ensure laser threat detection with a minimum number of sensors, thanks to the viewing angle preferably being greater than 90 degrees. Another purpose of the invention is; In the laser warning system put forward, by using lenses and/or mirrors and/or beam collectors, the incoming laser beams are separated according to their wavelengths and the beams that will create noise are filtered, thus reducing the size of the system and ensuring that there is no decrease in the viewing angle and spectral scanning, and the detection rate is increased and the detection rate is lower with less false alarm rate. is to ensure that the correct detection sensitivity is achieved. Another purpose of the invention is; The aim of the laser warning system is to prevent false warnings by preventing noise through the PCB (Printed Circuit Board) design that complies with EMI (electromagnetic interference) and EMC (Electromagnetic Compatibility) standards. Another purpose of the invention is; The aim is to minimize the number of false alarms by detecting the wavelengths of laser threats, preferably with high accuracy, using special photodiodes operating at certain wavelengths through the laser warning system. Another aim of the invention is to create a compact laser warning system, preferably less than 5 kilograms, that remains operational for a minimum of 24 hours without the need for recharging via lithium-ion rechargeable batteries. The invention is a laser warning system to fulfill the purposes described above, and its feature is; o oval lens, which is connected to the laser warning system box and increases the viewing angle of the photodiode by ensuring that the emitted laser beams are focused at a point; and the electronic card, which provides a warning to the user through a buzzer and/or vibration sensor, contains a photodiode that is connected to the said oval lens and detects the emitted laser light and produces signals at different voltage levels according to the intensity of the laser light in question. In a preferred embodiment of the invention, the viewing angle of said photodiode is more than 90 degrees. The structural and characteristic features and all the advantages of the invention will be understood more clearly thanks to the figures given below and the detailed explanation written by making references to these figures, and therefore the evaluation should be made taking these figures and detailed explanation into consideration. Figures to Help Understand the Invention Figure 1 is a representative representation of the laser warning system that is the subject of the invention. Drawings do not necessarily need to be scaled and details that are not necessary to understand the present invention may be omitted. Furthermore, elements that are at least substantially identical or have at least substantially identical functions are designated by the same number. Description of Part References Laser Warning System Laser Warning System Box Photodiode Oval Lens Electronic Card Detailed Description of the Invention In this detailed description, the preferred embodiments of the invention are explained only for a better understanding of the subject and in a way that does not create any limiting effect. Meet; A laser warning system (1) that can be mounted on wearable equipment or a vehicle or a fixed structure and ensures the safety of drivers and pedestrians thanks to the warnings it gives, and the laser warning system (1) that is the subject of the invention, as seen in Figure 1, the laser warning system box (2 ), photodiode (3), oval lens (4), electronic card (5) and buzzer (6). The laser warning system (1) contains a photodiode (4) that is connected to the oval lens (4) and detects the emitted laser light and produces signals at different voltage levels according to the intensity of the laser light in question. The said oval lens (4) is connected to the laser warning system box (2) and increases the viewing angle of the photodiode (3) by ensuring that the emitted laser beams are focused at a point. The oval lens (4) in question may preferably be a lens and/or mirror and/or beam collector. The signals obtained through the said photodiode (3) connected to the said laser warning system box (2) are sent to the electronic control unit via the communication unit. The electronic card (5) provides a warning to the user via buzzer (6) and/or vibration sensor, depending on the value of the signals in question. The buzzer (6) in question is located inside the laser warning system box (2) and therefore is not visible. Due to the situation in question, the buzzer (6) is shown with a dashed line in Figure 1. The laser warning system box (2) mentioned is preferably 40x40x40 cm in size for easy transportation. While the threat location sensitivity in laser warning systems in the current technique is approximately 15 degrees, in the laser warning system (1) in question, the viewing angle width of the said photodiode (4) is preferably more than 90 degrees. In this way, all kinds of laser threats are detected with the least number of sensors possible. TR TR TR
