The main disadvantage of this device is the limited scope of its application.

The technical problem to which this invention is directed is the expansion of functionality by increasing the class of simultaneously solved problems, increasing the profitability of the oil product supply enterprises.

In addition to process control, the device provides commodity accounting of petroleum products and cash flows during reception, sale and storage with automated preparation of the necessary reporting documents.

For the first time, it was possible to combine commodity and cash flows when receiving, dispensing and storing petroleum products at petroleum product supply enterprises.

The composition of hardware and software provides commercial accounting of petroleum products and balancing of the commodity balance by mass with an error of ± 0.5% for the petroleum product supply company with fiscalization of commodity and cash flows.

The specified technical result is achieved due to the fact that the device for metering oil products contains a central unit connected to a display unit, a printing unit and a communication unit, an information processing control unit connected to a display unit and a cash register with the functions of a fiscal registrar, a control unit and information processing through the interface lines is connected to the controllers of the zones of reception, storage and dispensing of petroleum products, which are connected through the interface modules to measuring instruments and and execution of commands, the central unit and the control and information processing unit are integrated into a local network, the communication unit via a radio channel is connected to the upper level of the automated control system, including geographically remote objects.

In addition, geographically remote facilities include a dispatch service and / or tax office and / or company office.

The invention is illustrated in the drawing, which shows a General diagram of a device for accounting for petroleum products.

A device for accounting for petroleum products contains means 1-9 for measuring and executing teams of zones 10, 11, 12, respectively, receiving, storing and dispensing petroleum products.

Means 1-9 for measuring and executing commands through interface modules 13-21 are connected to controllers 22, 23, 24 of the respective zones 10, 11, 12 for receiving, storing, and dispensing petroleum products.

In particular, the funds can be implemented as follows:

1 - volumetric meter for measuring the volume of petroleum products;

2 - pressure sensor;

3 - temperature sensor;

4 - sensor changes the level of oil in the storage tank;

5 - oil temperature sensor in the storage tank;

6 - sensor ρ (density);

7 - volumetric counter;

8 - pre-level overflow sensor;

9 - sensor monitoring the grounding of the tank car.

The device includes a central unit 25, an information processing and control unit 26, and a communication unit 27 connected via a radio channel to the upper level of an automated system including geographically remote objects: a dispatch service 28, a tax office 29, and an office 30 of a company.

The central unit 25 is connected to the display unit 31, the printing unit 32.

The control and information processing unit 26 is connected to the display unit 33 and the cash register 34 with the functions of a fiscal register, which allows you to register the movement of goods flows (income, expense and balance) and financial flows associated with this, which allows you to create a tax base.

Block 26 control and information processing through interface lines 35, 36, 37 is connected to the controllers 22, 23, 24, respectively, zones 10, 11, 12 of the reception, storage and dispensing of petroleum products.

The central unit 25 and the control and information processing unit 26 are integrated into the local network 38.

The device operates as follows.

The operation of the device is carried out under the control of software installed in the central unit 25 and the information control and processing unit 26, interacting with the controllers 22, 23, 24 of the zones 10, 11, 12 for receiving, storing and dispensing oil products, respectively, and providing information retrieval by means of material resistance sensors 1-9, convert the signals from the sensors and issue control actions on the technological equipment of the respective zones (loading of oil products, the state of the oil product during storage and reception).

From the dispatching service 28 through the communication unit 27, control commands and data are received in the central unit 25, in which the necessary tasks for the execution of a particular technological operation are generated.

In this case, the generated tasks are indicated on the display device 31. Through the local network 38, the commands and necessary tasks are transmitted to the information control and processing unit 26, which, in turn, through the interface lines 35, 36, 37 initiates the necessary controller 22, 25, 24 to perform the specified function.

The initiated controller generates discrete signals that are input to the interface modules 13-21, which are electronic devices designed to generate power and control signals to measuring and executing commands of zones 10, 11, 12 of respectively receiving, storing and dispensing oil products.

In addition, at the request of the information control and processing unit 26, the controller 22 collects information from measuring and executing commands on the maximum allowable pressures in the branch pipes, liquid temperature and flow rates.

In this case, all information about the technological process is displayed on the display device 33 in the form of tables, mnemonic diagrams, and the values of the controlled physical quantities of oil products.

To measure the physical parameters of petroleum products in storage zone 11 (the level of petroleum products in the tanks, temperature, density and level of produced water), measuring instruments were installed in the tanks.

Reading information from measuring instruments is carried out on request from the block 26 of the control and processing of information and the central unit 25.

Information through the communication unit 27 under the control of special software over the air is transmitted to geographically remote objects: the dispatch service 28, the tax office 29, the office of the company 30.

When selling petroleum products, information about a given dose is sent to the central unit 25, which, through the local network 38, gives permission to the control and processing unit 26 for dispensing the required petroleum product, while a command is generated via the interface line 37 from the information control and processing unit 26 24, which forms a control action on the means of execution of the commands of the oil product loading unit.

The result of the processing of commands is processed by the controller 24 and enters the control unit 26 and information processing and is displayed on the display unit 33 display.

The information management and processing unit 26 through the interface line 36 of the corresponding controller 23 requests data on the oil product from the tank measurement system and, through the local network 38, transfers the physical parameters of the required oil product to the central unit 25.

The central unit 25 generates on the printing unit 32 the corresponding supporting documents (waybill, invoice), enters information about the client and the oil product dispensed into the database, and generates information for transmission through the communication unit 27 to geographically remote objects.

Automatically from the central unit 25, the necessary information about the released or received oil product is entered into the fiscal memory of the cash register machine 34.

When accounting for petroleum products in storage zone 11 in the tank farm from the control and information processing unit 26, a request is sent to the controller 23 of the measuring instruments for measuring physical parameters (mass, volume, density, temperature, level). These data are processed in the control unit 26 and information processing and are entered into the database of the Central unit 25.

Based on these data, the central reporting unit 25 generates the necessary reporting documents and, if necessary, generates information for transmission through the communication unit 27 to geographically remote objects.

The invention will expand the functionality by increasing the class of simultaneously solved problems, increase the profitability of the oil product supply enterprises, ensure commodity accounting of petroleum products and cash flows during reception, sale and storage with automated processing of the necessary supporting and reporting documents.

The invention will allow for the commercial accounting of petroleum products and the reduction of the commodity balance by weight with an accuracy of ± 0.5% for the petroleum product supply company with fiscalization of commodity and cash flows.
