Description

Method and system for monitoring and ordering LPG cylinders online

The present invention relates to a method and system for monitoring the weight of LPG existing in a gas cylinder and online ordering of a new load at the moment when the gas cylinder is emptied.

US5614672 discloses a system for measuring the quantity and or volume of liquid contained in pressurized containers, which has a load transducer located in the container housing, the transducer which is mounted on a flange of an outer pipe, on the top of the tank. closed containing the measured liquid whose density is known. On the transducer is disposed a weight of the shape of an empty cylindrical piston, whose length can be modified, measuring system that works on the principle that when the container is empty, the maximum weight of the piston represents the zero point of the measuring system, the weight float of the liquid being presented as units of volume or weight, viewed through a measuring screen or a computer screen.

Also known from document RO 131285 is a system for measuring the level, quantity or volume of liquid stored in pressurized containers from liquid product depots, provided with some weight or volume transducers placed between some receptacles of the container or closed container and the surface of the container. support of the whole assembly, the transducers being connected by power and data transmission cables to the measurement system or to a computer.

It is known that LPG in our country for domestic users, is marketed in the unit of measure Kilogram. But oil products change their volume as a function of temperature, so that the exact quantity of LPG sold or bought can only be determined by measuring weight. It is also known that the packaging of LPG bottles is different in weight (country).

The system according to the invention is based on the difference between the total weight and the country of the cylinder, determining the net weight of LPG in the cylinder. The data on the country of the bottle is entered in the application at each change of bottle, following as after it is made

to 2017 00215

11/04/2017 calculations, issue warnings to the user and order for a new upload.

The application associated with the monitoring system draws up on the basis of the consumption reports from the usage history, an estimation of the moment of emptying the bottle. Also, when the LPG is at a minimum level in the cylinder, the user will be warned and at the same time the warning will be transmitted to the dispatcher.

The technical problem solved by the present invention consisted in monitoring the consumption of LPG (liquefied petroleum gas) from the gas cylinders and the online ordering of the loads.

This problem is solved by creating a method for monitoring the weight of LPG existing in a gas cylinder and a system for monitoring and ordering online the gas cylinders loaded with LPG.

The monitoring method consists of recording and identifying the cylinder, assigning the cylinder to one of the existing locations, identifying and registering the respective cylinder, weighing the cylinder with the weight sensor, transmitting the data obtained after weighing to the application server, establishing a transport of another full bottle in that location.

The existing LPG weight monitoring system for a gas cylinder and online ordering of the gas cylinders is composed of a technical part that provides the information and a software part that interprets the information, where the technical part consists of a positioned platform. under the gas cylinder, on which at least one weight sensor is mounted, a microprocessor that analyzes the data that has a short-range micro antenna, which are powered by a battery, the whole assembly being protected by a plate on which the cylinder is supported. , the data transmitted by the technical side being received by a Bluetooth module from the smartphone, tablet or computer that transmits this data to the application server, the software application registered on one of the above mentioned devices will communicate to the user the quantity in the bottle, in kilograms, in percent and will also communicate the information transmitted by you the server that manages the system, such as: the time of emptying according to the usage history, the updated prices of the products, etc.).

By applying the present invention the following advantages are obtained:

- the user will no longer care about the cylinder, will not have to make consumption estimates, will not have to keep a history of purchases, will not have to have uncertainties regarding the weight of gas purchased and will not have to order the cylinder, it will be brought home by system operators when empty.

- the user will see in the application the quantity of gas existing in the bottle at a given moment, will receive an estimate of consumption and will decide accordingly on the moment when he can receive a new load.

- extremely easy monitoring of the bottle

- safety in exploitation

- statistics can be created according to current or presumed consumption;

The following is an example of an embodiment of the invention in connection with the figures 1 which represents:

Figure 1 - view of the functioning of the on-line monitoring and control system of LPG cylinders;

The LPG weight monitoring system existing in a gas cylinder and online order of a new cargo according to the invention is composed of a technical part P which provides the information and a software part S which interprets the information, where the technical part P is consisting of a platform 1 positioned beneath the stove cylinder B, on which at least one weight sensor 2 is mounted, a microprocessor 3 which analyzes the data having a short-range micro antenna 4, which are supplied from a battery 5, the whole assembly being protected by a plate 6, which supports the cylinder B, the data transmitted by the technical part P being received by a Bluetooth M module from the smartphone, tablet or computer that transmits this data to the SR server of the application, the software application registered on one of the devices mentioned above will communicate to the user the quantity existing in bottle B, in kilograms, in percentages and of it will also communicate the information transmitted by the SR server that manages the system, such as: the clearing time according to the usage history, the updated prices of the products, etc.).

The B weight monitoring system includes a monitoring unit

UM and sensor 2 for detecting LPG weight in the cylinder. Each sensor 2 is of 2017 00215

11/04/2017 in functional communication with the UM monitoring unit through adequate wireless communication. The weight sensor 2 is functionally mounted on the cylinder so that its damage is prevented by the load stored inside the cylinder.

The monitoring method consists of recording and identifying the cylinder, assigning the cylinder to one of the existing locations, identifying and registering the respective cylinder, weighing the cylinder with the weight sensor, transmitting the data obtained after weighing to the application server, information is transmitted by the server The SR that manages the system, such as: the emptying time according to the usage history, the updated prices of the products and at the last stage, is established for a transport of another full bottle in the respective location.
