For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawing and specific language will be used to describe the same.
It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated system, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skilled in the art to which this invention belongs.
Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The present invention herein relates to the field of a vehicular pollution detection system using more specifically an IoT based control system. Every vehicle emits or release pollutants that become the reason for leveraging the level of air pollution. This emission depends on the quality or nature of the fuel that is fed to the vehicle. Various emissions such as Carbon Monoxide, Hydrocarbons and Oxides of Nitrogen are the pollutants that are released by vehicles which form the area of concern.
The present invention consists of various phases that help to study the working. The working of present invention starts by setting up of the system or devices in the vehicle. After the device is set up with the availability of Wi-Fi, thresholds for different emissions are set up in accordance with the government rules. When the vehicle starts, the phase of sensing of emission, i.e., data sensing starts. The data is continuously transferred to GitHub in regular intervals and with this, the phase of monitoring starts. After monitoring, data analysis is carried on which helps to determine the actions.
Setting up the system in a vehicle
The information about the pollutants or the nature of pollutants from the vehicles is known. Therefore, the first phase involves a connection in between the hardware devices that would be attached to the vehicle and also ensure the working of software tools that are needed. The Wi-Fi connection needs to be active, that is, there should be the availability of the Internet. The phase involves connection set up in such a way that it would not delay the working of a vehicle but would also be able to continue in its process effectively. Once the setup is done then there is no need of interaction from humans.
Setting up the threshold
In this phase, the thresholds setting are done that depends on the standards set by the government. The threshold of a particular pollutant reflects the limit up to which the concentration of the pollutant is safe to emit to the environment that is the maximum limit till which no actions would be taken. If a vehicle crosses this limit, then there would be a problem. The thresholds set may be different or maybe same that depends upon the type of vehicle.
Sensing of data
Up to this phase, the system is attached to the vehicle. The vehicle can go anywhere and then this phase starts. In this phase, as the vehicle is doing different actions, the sensors are collecting the data regarding the levels of the emission of the different pollutants. The data is converted to PPM standard but, this data is not sent directly to the server because it is not necessary that a vehicle is producing the emissions above the threshold always, keeping this fact in mind, a solution is proposed in which the average of the data from a single day for ach pollutant would be sent for further procedure.
Monitoring
After the sensing part of the system the desired output has reached to the GitHub and at this repository the monitoring could be done in public domain. In the monitoring phase the data is checked for a vehicle and if the data of a vehicle is continuously crossing the threshold for a specific period of time, then this indicates that the vehicle needs servicing and the alert for the same would be sent to the owner and to the traffic police department.
Actions for controlling
Till this phase the 90 per cent of the work of the system is done. The actions would be set in a manner to spread awareness and not the terror. The actions should be fair for everyone. The data after being sent to the traffic police would be their property and they would issue fine for the vehicle under the consideration.
To further clarify advantages and features of the present invention, a more particular description of the invention is rendering by reference to specific embodiments thereof, which is illustrated in the appended drawing.
While, specific language has been used to describe the present invention, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.
The disclosure herein (Figure 3), provides the information about the pollutants or the nature of pollutant from the vehicles is known with the help of sensor array (105). In one embodiment, signal conditioning circuit (110) is designed to convert the 4mA compatible with the voltage range of the built-in analog-to-digital converter chip- Controller Unit (112). In another embodiment, Analog to Digital Converter chip again convert the value to the standard SI unit i.e. (Parts per million PPM)-Controller Unit (112). In another embodiment, the data is communicated with the help of LoRa Gateway (114).
Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
