BACKGROUND OF THE INVENTION The invention relates to the field of devices and is intended for the accounting, control and management of heat energy consumed in cogeneration heating systems.

There is a known method and device for determining the user parameters required for distributing the cost of heat consumed. In electronic price allocators, the cost of the heat parameter is usually determined by measuring the difference in temperature between the heated element and the air in the room. Such a fixed expression cannot assess the actual environment and working conditions of the individual heating element. To avoid these problems, the method of determining and the electronic heating cost distributor measures the rate of cooling during the cooling of the heating element by interrupting the flow of the heat carrier. Based on this size measurement, it individually determines the functional relationship between heat transfer and temperature difference (see German Patent No. 4122848, GOi K17 / 08, 1994).

There is a known electromagnetic heat and water meter and its mode of operation. The meter consists of three flow sensors, four temperature sensors. indicator, voltage polarity switch, analogue switch, interference compensation unit, microprocessor with control unit, memory unit, standard output signal unit, input amplifier, normalizing amplifier-switching device and reference impedance connected to one of the voltage-polarity switching and analogue switches, the digital data bus of which is connected to a microprocessor data bus, its control bus is parallel connected to a microprocessor control unit, an analog signal switch, a gain amplifier switch, an interference compensation unit and a voltage polarity switch, and its output data and address bus is parallel connected to an indicator with frequency and current outputs, the other four inputs of the analog switch are connected to the outputs of the four temperature sensors, and the sixth input is connected to the normalizing power an output of a commutator switch with inputs via an interference compensation unit and an input amplifier connected to each output of the flow sensors with excitation windings connected to a voltage polarity commutator

The indicated meter operates as follows: it calculates the inlet and outlet heat carrier and hot water temperatures, flow rates and mass of hot water used, and determines the amount of heat energy used to heat the premises and hot water according to the formula:

E = V2 xy 2 (h1 - h2) + (72 ^ 3 - V3y4) (h1 - h2) where:

Vi, V2, V3 - amounts of water flowing; water densities;

E ,, k · - temperatures corresponding to enthalpies Τι, T2 T3, Te.

(See Patent No. 4237 of the Republic of Lithuania, GOIK17 / 16, inventions, industrial design, trademarks, trade names '', 1997).

The specified meter and its mode of operation, like its counterpart, cannot control the precise accounting and billing of energy carriers.

The object of the invention is to control, manage the accounting of heat energy carriers and to increase the accuracy and expediency of settlement thereof.

The stated aim is achieved by calculating heat carrier temperatures, flow rates and amount of heat in the method of heat energy accounting with the prepayment system, determining the functional dependence between the heat energy consumed and billing information with the heat supplier, which it reads from the integrated circuit card and adjusts or reduces the amount of heat energy to a minimum that still ensures the heating system does not freeze, depending on the billing information read with the heat supplier at the prepaid facility.

We achieve this goal by providing a device with a prepayment system consisting of a meter consisting of flow sensors. temperature sensors connected to a processor having an indicator connected to an output, a newly introduced prepaid device with an integrated circuit card consisting of a processor-controller connected to a memory unit, a timing unit, a control matching unit to which an indicator and a smart card reader are connected; a recording unit into which the smart card is inserted and a controller connected to a prepaid device control and recovery unit to which a heat meter processor is connected.

Fig. block diagram of a device with a prepayment system illustrates a device 1 with a prepayment system consisting of a meter 3 consisting of a flow sensor 2, a temperature sensor 3 connected to a processor 4 with an output indicator 5 connected to the processor 4 via a control and matching unit 6. a prepayment device 7 comprising a processor-controller 8 to which a memory unit 9 and a time measurement unit 10 are connected, an indicator 11 and a chip card reading and writing unit 12 to which the chip card 13 is inserted.

Controller 14 connected to control unit 6.

Heat billing in a unit with a prepayment system is done as follows.

Information about the amount of heat consumed from processor 4 of heat meter 1 passes through control and matching unit 6, processor controller 8, to memory unit. 9, in which it is recorded together with the time recording, from the time measurement unit 10. The processor controller 8 calculates the amount of moneyPE according to the tariff table and the amount of heat consumed and writes it to the memory unit 9, which is energy independent. inserting an integrated circuit card 13 with information about the amount paid, money P, tariff table T and user identification code K into the smart card reading and writing unit 12 and other information (discounts, refunds) required by the consumer and the supplier. This information is written to the memory unit 9 of the prepaid device 7. The processor controller 8 subtracts the sum Ρε, proportional to the amount of heat consumed, from the paid money amount and writes the result to the memory unit 9. The processor 8 of the prepaid device 7 compares Ρε with P and at P Pe, activates regulator 14 via control and adjustment unit 6 which reduces the heat supply to a minimum while still ensuring the heating system does not freeze. In this mode, the user is required to pay a new amount of money to the heat metering center, which is again recorded on the smart card 13 and written to the prepayment device 7. The latter sends a signal to the heat controller 14 and returns to normal heating mode.

The user, through the control and adjustment unit 6, can find out the amount of money paid. its balance, the amount of energy used, the tariffs, and the real time cadence. All this information is contained in Indicator 11.

Compared to the prototype, the new set of structural elements allows to accurately calculate, store, store data on heat consumption, control the billing of consumers, manage and regulate the heat supply to the consumer.
