1 TARIFF REMOTE SENSING TECHNOLOGY FOR VEHICLE EXHAUST EMISSIONS MEASUREMENT SYSTEM Technological Field: This invention reduces exhaust emissions from moving vehicles without stopping the vehicle. measuring, optical transmitter-receiver and passive reflector positioned on both sides of the path using a camera system that detects vehicle license plates together with its mechanisms It relates to remote sensing systems. 10 State of the Art: Today, in order to determine the exhaust emissions of vehicles, the vehicles are tested. methods by which the device is stopped and connected to fixed or laboratory-type measuring devices is used. In such methods, taking a sample from the vehicle involves the vehicle being in a specific 15-degree position. holding in position or the measurement process within a controlled test procedure It is necessary to implement the emissions of vehicles in the actual traffic flow. In terms of determining their behavior, these methods involve interrupting traffic flow and... Their ability to scan a large number of vehicles in a short period of time can limit their capacity. In optical remote sensing systems that operate on the open path principle, the exhaust of vehicles the effect created in the optical beam by the gaseous components within the clouds Emission estimation is based on absorption or attenuation. However, the single In transmissive optical systems, the distance that light passes through the exhaust cloud is limited. due to factors such as ambient light effects, separate power supplies for the transceiver elements on the opposite side of the road, and 25 the need for communication infrastructure and time synchronization between cabinets Technical issues may arise, such as the need for mandatory requirements. Furthermore, simply measuring the gas emissions indicates which vehicle the measured emissions belong to. It is not always possible to determine this precisely. Especially if there are more than 30 at the same time. too many vehicles passing through the measurement corridor, vehicles moving in different lanes, or exhaust fumes In situations where the clouds are dispersed by the wind, the emission data can be obtained with the correct instrument. Matching the optical measurement system with the camera-based system is becoming increasingly important. License plate and vehicle movement detection must operate simultaneously. 2 Current systems also measure natural air concentrations in the measurement area. If the separation from the result is not done adequately, from the vehicle exhaust the resulting increase in gas and the background gas already present around the road Their concentrations can mix. This situation means that emission values ​​may be 5 This can lead to it being evaluated as higher or lower than it actually is. Therefore... background air quality in the measurement area before and during vehicle passage Determining and differentiating it from vehicle-induced optical changes is a technical requirement. It constitutes. However, stopping the vehicles and checking stationary or laboratory-type measuring devices traffic flow interruption and actual driving that occurs in the methods it connects to The problem of the inability to directly represent the conditions lies between the two sides of the path in the invention. with the creation of an open road optical measurement setup and taking measurements without stopping the vehicle is being eliminated. 15 In single-pass optical measurement setups, the optical beam passes through the exhaust cloud. Due to the short effective distance traveled, the measurement signal weakens and The problem of not being able to perceive short-lived exhaust clouds clearly enough is addressed in the optical design of the invention. the light beam is reflected back from the corner cube mirror inside the passive reflector cabinet It is eliminated by passing it through the exhaust cloud in a double-pass manner. 20 On the other side of the road are active transceivers, power, processors, or communication components. In optical systems, establishing a separate infrastructure and cabling for the counter cabinet is necessary. The problem of the need for power supply, power supply, and time synchronization between cabinets is addressed in the invention. The passive reflector cabinet contains a corner cube mirror that serves only the optical back reflection function. 25 transport and main module cabinet containing transmitter, receiver, control, power and communication components It is eliminated by collecting them. It only measures gas levels and does not generate measurement data along with the vehicle ID. in systems, when there are multiple vehicles or different lanes at the same time, 30 The problem of not being able to correctly associate emission data with the vehicle is addressed in the invention's camera module. license plate recognition and image processing unit, artificial intelligence / processor module, and speed and acceleration. vehicle movement information generated by the computing unit with optical measurement data. time matching via system control unit (16) is being eliminated 35 3 Total optical change in the exhaust cloud only, without measuring background air composition. In the measurement setups that evaluate, the gases already present around the road The inability to separate the additional emissions from the vehicle related to the concentration. The problem is that the background air quality measurement unit in the invention is not present before and / or during vehicle passage. It takes measurements between vehicle crossings and this unit of gas concentration and optical analysis This is resolved by subtracting the value from the exhaust cloud measurement. Therefore, the technical solution of the invention is consistent with what was presented in each of the previous technical examples. In response to a specific problem; open road measurement without stopping the vehicle, double pass. optical path, passive reflector housing without active electronics, camera-based vehicle license plate 10 the combined use of matching and background air quality correction mechanisms It is based on.

It correlates vehicle emissions with motion data, resulting in a recordable emission test. It converts it into data. Thus, it can be used in fixed test setups or in a controlled environment of the vehicle. A large number of vehicles' emissions were not required to be stopped in the test area. The aim is to monitor the situation. Another purpose of the invention is to create a connection between optical units placed on either side of the path. The created open path works through an optical measurement setup. The main one is located on one side. Infrared and ultraviolet rays emitted by the module are used for measurement along the path. after passing the area, it turns back over a passive reflector located on the opposite side. This ensures the reflection of the rays. Thanks to this double-pass optical path, the rays are reflected from the vehicle exhaust 30 The effective distance through which the cloud passes is increased, and the exhaust gas beam the absorption effect it creates is perceived more clearly This is the goal. In this way, emissions, especially those generated during vehicle crossings, are particularly targeted. The aim is to measure the cloud more reliably. 35 4 One of the key aims of the invention is to activate the reflector unit located on the opposite side of the road. to operate without needing electronic, power supply or communication infrastructure The aim is to ensure the reflection of the optical beam through a passive reflector element.

The aim is to extract related speed or acceleration information. Camera data and optical data. By synchronizing emission measurements over time, multiple vehicles can be monitored. Accurately associating emission data with the correct vehicle when passing through the same road section. is intended. 20 Another purpose of the invention is to measure the natural environment present in the measurement area before vehicle passage. The goal is to determine the air components and background gas concentrations. Air quality around the road, emissions from previous vehicles, and the surrounding environment (25) It can change due to weather conditions or meteorological factors. Therefore, the system... not only measuring the total gas effect in the exhaust cloud but also vehicle passage It also takes into account the previous background weather conditions. Background values By isolating it from the exhaust cloud measurement, it can be determined how much of the measured gas increase is relevant. The aim is to more accurately determine whether the problem originated from the vehicle. 30 The invention also combines signals obtained from infrared and ultraviolet measurement channels. by evaluating and calculating the exhaust gas composition and concentration level The aim is to differentiate between the intensity of the transmitted light and the intensity of the received light. Measurable data regarding gas components are generated through processing. Vehicle passage 35 during the initial, peak, maximum, and decrease phases of the emission event By monitoring the exhaust cloud over time, instead of relying on just a single instantaneous value, The aim is to evaluate the behavior within the organization. Another objective of the invention is to automatically evaluate the reliability of the measurement result. The aim is to provide a data validation structure. In this regard, the adequacy of the optical signal level, The passage of the exhaust cloud through the measurement area, the stability of background weather conditions, the plate the accuracy of the measurement, the vehicle's position in the measurement area, and the suitability of environmental conditions They are evaluated together. This determines whether the measurements are valid, invalid, or need to be re-evaluated. records that need to be evaluated are classified as such, and erroneous matches are 10 The aim is to reduce it. Another purpose of the invention is to combine emission measurement data with license plate information, vehicle image, speed, acceleration, complementary factors such as strip, measurement time, background air quality and environmental conditions. The goal is to keep all the information together in a single record. This integrated record structure allows for high-level...
