1 TARIFF MODULAR SLALOM POLE BASE WITH PHOTOELECTRIC SENSOR WIRELESS AGILITY, SPEED AND REACTIVE PERFORMANCE MEASUREMENT AND EVALUATION SYSTEM 5 Technological Field: This invention has applications in sports science and performance analysis, including football, basketball, volleyball, handball, and Field and indoor sports like tennis, athletics, speed and agility tests, physical medicine and 10 rehabilitation, return to the field and performance monitoring, school physical education, sports academies, electronic timing systems, sports technologies, mechatronics and Modular slalom with photocell sensors that can be used in wireless sensor network applications. Stick-based wireless agility, speed, and reactive performance measurement and evaluation. It is related to the system. 15 State of the Art: Today, sports science encompasses performance analysis, athletics, field and indoor sports, and In physical performance assessments, athletes' speed, agility, and change of direction are 20 various electronic timing systems for measuring performance It is used in this sector. In this context, Brower TCi, Microgate Witty, and VALD are among the products used. SmartSpeed ​​and Freelap-like wireless photocell-based timing systems These systems utilize infrared or similar optical sensing methods. Timing gates that utilize these technologies are often mounted on a tripod or separate carrier. 25 The elements are placed on the athlete's designated starting, intermediate measurement or time based on the principle of the optical beam being interrupted when passing through the endpoints. Measurements are being taken. The course is being created and the athlete's direction of movement is being determined. For the purpose of determination, a purely mechanical structure independent of the electronic measurement system was used. Slalom or agility poles are used. 30 2 In known techniques, photocell-based timing gates are used for course guidance. The fact that the slalom poles used are in independent product groups, the transportation and separate installation of numerous pieces of equipment during the application This requires photocells to be placed at appropriate measurement points along with their tripods. positioning, manual alignment of opposing sensors and slalom 5 The rods must also be positioned according to the test protocol to be applied. This is especially true for agility and change of direction, which have a large number of measurement points. This leads to longer installation times on the tracks, reduced portability, and equipment issues. This increases the quantity and thus the system cost. In current photocell-based timing systems, gates such as start, intermediate passage, and end can be controlled using photocells. Roles may need to be manually defined by the user, and the course The physical distances between the measurement points forming the system are determined automatically by the system. It cannot be measured and verified. Therefore, 10 m and 20 m sprint tests and the Illinois, T- Test 15 features specific layout geometries such as 505, Pro-Agility, and Zig-Zag. During the setup of the tests, the distances must also be measured by the user, and The equipment must be positioned in accordance with the relevant protocol. Placement the inability to automatically determine its geometry and the application based on this geometry The test protocol cannot be recognized automatically; the setup is dependent on user experience. this situation and the measurement resulting from incorrect distance or positioning 20 This can lead to differences becoming apparent. In photocell-based measurement systems, when a single-level optical beam is used... before the athlete's torso crosses the measuring line, limbs such as arms or legs Cutting the beam causes the timing event to be triggered at an unintended moment. 25 It is possible. Additionally, optical sensing structures aligned with a specific direction, Use in versatile course layouts where approaches are available from different directions. This can limit its flexibility. The planned geometry of the course versus the situation on the field. Automatic detection of discrepancies between the actual placement and the reported placement. The inability to measure these values ​​is particularly problematic in standardized performance tests. a technical deficiency in terms of repeatability and comparability It constitutes. 3 On the other hand, in reactive light-based training systems like BlazePod and FitLight The athlete is given random or pre-selected visual stimuli to test their reaction and Decision-making focused training can be conducted. However, this type of training... systems, the precise passage detection offered by photocell-based timing gates and 5 It cannot provide the time measurement function within the same technical framework. Therefore... precise speed and agility timing combined with reactive decision-making tests In applications where different types of hardware and systems are desired to be implemented separately They may need to be used separately; measurement, training and performance tracking processes It is becoming difficult to manage it through a single and integrated platform. 10 Description of the invention: Thanks to this invention, slalom and agility can be achieved with precise timing functionality based on photocells. The navigation function used in the courses is on a single modular and wireless body with 15 They are assembled together. The photocell sensors are directly attached to the slalom pole body.

It can bring them. Thus, the parts that need to be transported, placed on site and installed A more portable and faster-to-set-up measurement and training system by reducing the number of equipment. 20 The platform is obtained. The invention involves UWB-based time-of-flight measurement between rods. This is done by automatically adjusting the distances between the rods. This enables calculations. The obtained distance and settlement geometry data are 25. 10 by comparing it with a template library containing standard test protocols test protocols such as 20 m and 20 m sprint, Illinois, T-Test, 505, Pro-Agility and Zig-Zag It is possible to automatically recognize the created track geometry. This structure becomes the case after the system's deployment. This enables the implementation and faster initiation of the measurement process. 30 It provides. 4 Thanks to its UWB-based automatic distance measurement and verification feature, it tracks the course. The positions of the rods forming the structure and the distances between them can be controlled. The compatibility of the planned track geometry with the actual layout on the site can be determined. Planned layouts and a track creator available via a mobile application. The deviations between the physical layouts implemented are automatically recorded as 5. verifiability is ensured by standard test protocols conforming to the prescribed geometric conditions. This contributes to the application of the method. In this way, the reliability of the measurements is improved. repeatability and performance tests conducted at different times Comparability is being increased. The invention uses infrared beams positioned at two different heights. by comparing perceptual information from the athlete's arm or leg movements This allows for the filtering out of erroneous interruptions that may occur. Thus, the true more reliable identification of the transition event and precise timing data. It is possible to increase its accuracy. In addition, there is a 360° sensing alternative. 15 Thanks to its versatile course, there are approaches and transitions from different directions. By enabling the creation of patterns, the system's agility and adaptability are enhanced. The flexibility of use in testing is being increased.
