Description:Brief Description of the Drawings

The present disclosure generally relates to monitoring systems for fuel containers and particularly to a gas level monitoring system for a liquefied petroleum gas (LPG) cylinder.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Liquefied Petroleum Gas (LPG) is a critical fuel source globally, utilized extensively in domestic, commercial, and industrial applications. It comprises flammable hydrocarbon gases, primarily propane, butane, and propylene, liquefied for ease of storage and transport. The common uses of LPG include heating, cooking, and as fuel for vehicles, especially in regions where it serves as a primary energy source for cooking in urban households. Despite its wide applications, managing LPG inventory and ensuring its efficient use remain challenging across various sectors.
One conventional method employed in the management of LPG involves manual monitoring techniques. For instance, in residential and commercial kitchens, the estimation of gas levels traditionally relies on observing the color and size of the flame. This method, however, is highly inaccurate and does not provide real-time data on gas consumption or remaining levels, leading to inefficiencies and increased risk of running out of gas during critical times, such as cooking in restaurants or in household kitchens.
Further, in industrial settings such as power plants, substantial quantities of propane are wasted daily due to inefficiencies in fuel management. Traditional methods here often involve periodic checks and estimations rather than precise measurements, leading to significant propane wastage. The reliance on manual inventory techniques not only contributes to operational inefficiencies but also increases the environmental burden due to excess emissions.
Moreover, the procedure for replacing LPG cylinders, particularly in high-demand environments like restaurants, is time-consuming and often leads to operational disruptions. This process typically involves manual handling and installation of heavy cylinders, compounded by the lack of quick mechanisms to verify the amount of gas left in the cylinders. Such delays can affect service delivery and customer satisfaction in fast-paced settings.
The problems extend to safety concerns associated with the handling of gas cylinders. Inaccurate knowledge about the gas levels can lead to dangerous practices, such as attempts to manually check gas levels or improper handling of cylinders, which can cause leaks or accidents. The invisibility of gas further complicates this issue, as conventional cylinders do not allow for an easy visual check of the remaining gas levels.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and techniques for efficient and safe management of LPG inventory and usage.

FIG. 2 illustrates a function block diagram of a gas level monitoring system, in accordance with the embodiments of the present disclosure. At the core of the system is the Node MCU, which serves as the central processing unit. Data regarding the weight of the LPG cylinder is measured by the load cell and conveyed to the Node MCU. The Node MCU is tasked with analyzing the weight data, which is a critical parameter for determining the level of gas remaining in the cylinder. Upon processing the data, the Node MCU interfaces with the Blynk Platform to output the weight information. This platform acts as an intermediary that facilitates the transmission of weight data to the user, offering a user-friendly interface for monitoring purposes. Simultaneously, the Node MCU is linked to an MQ6 gas sensor, dedicated to detecting the presence of gas in the vicinity of the LPG cylinder. In the event of gas detection, which may indicate a leakage, the Node MCU triggers the buzzer. This buzzer, upon activation, emits an audible alarm to notify individuals in the immediate area of the potential safety hazard. Furthermore, the Node MCU, after processing the weight data, initiates a notification protocol to the user. This notification, which may be in the form of a message or an alert on a connected device, informs the user of the current LPG level, especially if it falls below a certain threshold. The integration of these components—load cell, Node MCU, MQ6 gas sensor, and the Blynk Platform—creates a robust system designed to provide real-time updates and alerts, ensuring both the convenience of knowing the gas levels and the safety of the environment around the LPG cylinder.
FIG. 3 illustrates a flow diagram of a gas level monitoring system, in accordance with the embodiments of the present disclosure. Initiation of the system is followed by the load cell measuring the weight of the LPG cylinder, which constitutes the primary action in the monitoring process. Upon obtaining the weight, the system evaluates whether the measured weight falls below a pre-determined threshold. If the weight is indeed below the threshold, the system activates a local alert via a buzzer and simultaneously, the user receives notification through the internet, ensuring the user is informed about the potential need for a cylinder refill. In parallel to the weight measurement process, the gas sensor initiates its function to monitor the environment for any LPG leakage. Should the gas sensor detect the presence of LPG in the vicinity, indicating a leak, the system then follows the notification protocol as outlined for low weight alerts. After the user has been notified of either condition—low gas level or gas leakage—the system is configured to repeat the process, maintaining vigilant surveillance over the LPG cylinder. This cyclical process guarantees that the gas level monitoring system remains proactive in reporting critical information, thereby ensuring safety and providing convenience to the user. This flow diagram encapsulates the systematic and automated approach employed by the gas level monitoring system to address both routine monitoring and emergency situations, reflecting the system's comprehensive design to manage LPG cylinder usage effectively.
FIG. 4 illustrates an exemplary prototype of a gas level monitoring system, in accordance with the embodiments of the present disclosure. The visual representation exhibits a three-dimensional model, comprising a circular top plate that is likely intended to support an LPG cylinder. Beneath the top plate, a robust base structure is discernible, featuring a central housing which may accommodate the monitoring electronics such as the microcontroller and communication modules. Four cylindrical supports are affixed perpendicularly to the base, potentially functioning as the housing for the load cells which measure the weight of the cylinder resting above. These supports appear to ensure stability and provide a conduit for transmitting the load to the measuring devices housed within. The construction suggests a compact and efficient design focused on accuracy in weight measurement and stability in cylinder support. This prototype reflects the practical application of the gas level monitoring system’s components and serves as a foundational model for subsequent iterations and production.
