Description

The utility model can be used to account for the consumption of both gas and diesel fuel in autonomous fuel supply systems, including private residential buildings, manufacturing enterprises and other types of residential, commercial and industrial real estate.

Currently, one of the most acceptable ways to solve the problem of autonomous fuel supply, in particular, problems of heating, gasification and electricity supply, is to install an autonomous gas supply system. Such a system has a fairly simple device, in general, including a tank for liquefied gas or another type of fuel, consisting of one or several separate containers, a gas main and a set of gas equipment indoors (see, for example, http://teplo71.ru/ articles / otoplenie / id_6.html). With the obvious advantages of such systems (autonomy and environmental friendliness), there is a certain drawback in their operation, associated with the need for periodic monitoring of the fuel level in the tank and, as a consequence, its timely replenishment, which can cause some inconvenience in the case of, for example, a long absence of consumers, for example, in the place of residence, in the particular case of residential objects and not only.

The problem to be solved during the creation of the claimed system consists in the possibility of remote control (monitoring) of the fuel level in the tank of the autonomous fuel supply system, mainly in cases of prolonged absence of consumers or without their direct participation in such control, while the technical result achieved by solving the set tasks, is to simplify and facilitate the operation of autonomous fuel supply systems, as well as to increase safety in the operation of such systems.

To achieve the set result, a gas fuel consumption metering system is proposed for autonomous fuel supply, consisting of a control unit configured to be installed in the consumer’s premises and connected to metering units and a dispatcher, respectively, while the metering unit serves to control the fuel level in the tank and transfer information to the control unit about the level reaching the set minimum value and / or operational information about the fuel level in the tank, the control unit serves to transmit Teaching about the level of information to the controller unit, and the latter used to issue commands to the direction to the tank car, tanker and / or billing consumers for the used fuel.

An embodiment of the system assumes that if a fuel leak is detected, the dispatcher unit has the ability to issue a command to turn off the fuel supply to the fuel supply components.

In general terms, the claimed system provides the possibility of telemetry, i.e. measuring and tracking at a distance the fuel level in the tank of the autonomous fuel supply system of both private, including suburban, residential buildings, manufacturing enterprises, and any other types of residential or commercial real estate, and structurally consists of three blocks - a system control unit (A), installed in the premises of the direct fuel consumer and associated metering unit (B) and dispatcher unit (C).

Block (A) in its general form includes a controller (processor) that performs the functions of monitoring the elements of the system, receiving and saving the measured parameters and transmitting data about the fuel level and the general condition of the system to block (B), and a gas meter connected to the processor (usually , pulse) of a known design, built into the fuel supply system from the tank of the autonomous fuel supply system and its subsequent distribution to direct consumption devices, a monitor display of controlled parameters (for example LCD monitor), at least one fuel leak sensor and a data transmission device per unit (B). Additionally, at least one blocking valve installed on the corresponding fuel supply pipe (both general and to individual components of the fuel equipment) and connected to the corresponding leakage sensor can be included in the unit (A) to increase the safety of the operation of the system, and also associated with the processor receiving antenna, the purpose of which will be explained below. Structurally, block (A) can be made both as a single device combining the listed components in one housing, and as an arrangement of the listed components in different parts of the consumer’s premises based on convenience and safety requirements (in the case, for example, of several fuel leakage sensors) .

Block (B) is made with the possibility of direct installation on a remotely located fuel tank and serves to control the fuel level in the tank and transmit the received data to the processor of block (A). To perform the respective functions, block (B) contains a fuel level sensor connected to its control device and to ensure autonomous operation. Both components are connected to the controller (processor) either directly via a wired communication line or through a transmitting antenna, which in this case is also part of the unit and connected with the receiving antenna of the unit (A). To increase the security level of the system as a whole, block (B) can also be equipped with a fuel leakage sensor and a blocking system for its supply to the fuel supply components in the consumer’s premises.

The dispatcher block (B) carries out general control over the functioning of the entire system as a whole, analyzing and saving data on the fuel level and the general condition of the system received from the processor of the block (A). The structural composition of block (B) in general terms does not differ from well-known systems for receiving and processing information and is not considered in this application.

It should be noted that the possible endowment of block (B) with the function of directly transmitting data on the level of gas fuel to block (B) in order to exclude block (A) from the system, with the seeming simplification and cheapening of the system, generally reduces its safety level, since deprives the system of the ability to control fuel leakage from individual components of the fuel equipment, and also eliminates the system’s ability to record fuel consumption by such individual components and, as a result, deprives the system of optimized fuel consumption. In addition, based on operating conditions, the fuel tank is placed outside the consumer’s premises and the inclusion in the block (B) of the elements of the block (A) that are sensitive to external operating conditions, such as, for example, a controller (processor), significantly reduces their service life and leads to to the final rise in price of the entire system as a whole.

The principle of operation of the claimed accounting system is based on continuous monitoring of the fuel level in the tank, transferring the received data to the dispatcher unit and, upon reaching such a set minimum value, informing the consumer about the need to replenish fuel reserves and, upon receipt of such consent and / or depositing funds , issuing a command to replenish the fuel level with a simultaneous direction to the tanker tanker tank. It is obvious that the described system can fully function in offline mode without the direct participation of consumers, whose responsibilities, in essence, are reduced only to making timely payments in accordance with the terms of the contract with the service organization. A variant of the system’s functioning upon reaching the minimum permissible fuel level may also involve shutting down individual (or all) elements of the fuel equipment by the system in accordance with the established priorities to maintain only the heating system in working condition.

It is also obvious that the system itself (without the participation of consumers) can inform the dispatcher unit about a fuel leak with the possibility of subsequent emergency calls or repair services, while blocking the supply / distribution of fuel. The possibility of connecting the claimed system with the general fire safety system of the consumer’s premises allows to shut off both the total fuel supply from the tank to the fuel equipment indoors in case of a fire hazard, and the fuel supply to the individual components of the fuel equipment (cooktops, boiler, gas steam humidifier, fireplace , barbecue, bath (sauna), gas power generator, gas power station, etc.). In case of integration of the system into the general automation system of the Object (such as fire, burglar alarms, remote control of climatic and other parameters of the Object that are components of home automation systems according to SS sections - low-current systems), the controller (processor) can be both its integral part and platform-forming base.

The claimed control system in significantly facilitates for the consumer the domestic and commercial operation of autonomous fuel supply systems (gas or diesel fuel), and for the supplier (operating organization) allows to provide relevant services more quickly and efficiently.
