The disadvantage of this utility model is the lack of technical ability to limit or shut off the supply of electricity to the consumer, for example, if he violates the terms of payment for electricity consumed.

A known method and integrated system of individual metering and regulation of energy consumption in housing and communal services (RF Patent No. 2378655, G01R 11/00, 2008). The system contains for each consumer of energy resources a series-connected power electric network, a specialized counter-calculator of consumed electric energy, an electric power sensor and a consumer load, as well as a data collection and control device connected via a bi-directional communication channel with unique identification addresses to the second input of a specialized counter-calculator of consumed electricity.

The disadvantage of this system is the lack of a specialized managed module to force the power supply to be cut off for consumers who violate the terms of payment for electricity consumed.

Closest to the claimed technical solution is "Automated information-measuring system of accounting, control and management of energy resources in the housing and communal services" (RF Patent No. 78966, G01F 17/40, 2008), adopted as a prototype and containing for each energy consumer series-connected power electric network, specialized counter-calculator of consumed electric power, module of forced shutdown of electric power supply and consumer load, as well as a pick-up device cottages and control data, connected by the bidirectional communication channel shared with unique identifying address to a second input of each counter-specialized power consumption calculator, and Workstations based on personal computers.

The disadvantage of this system is its limited technical capabilities, determined by the lack of operational information transfer directly to consumers, as well as the inability to control the functioning of the modules for forced power outage.

The technical result of the claimed device is to expand the technical capabilities in the implementation of control and information functions.

The technical result is achieved by the fact that the multimedia energy monitoring and control system contains, for each energy consumer, a power network connected in series, a specialized meter-calculator for consumed electric power, a power cut-off module and a consumer load, as well as a data acquisition and control device connected through a bidirectional shared communication channel with unique identifying addresses from second m by the input of each specialized counter-calculator of consumed electricity, and workstations based on personal computers, as well as a server, a computer-collector, a central control room and “n” structurally identical local information-measuring units for monitoring, accounting and energy management, connected in bidirectional shared communication channels with unique identification addresses with a data acquisition and control device connected via bi-directional shared communication channels with a uni kalny identification addresses with a collector computer connected via bi-directional communication channels of general access with unique identification addresses to workstations based on personal computers, to the server and to the central control room, and each local information-measuring unit for monitoring, accounting and energy management includes series-connected power electric network, specialized counter-calculator of consumed electric power, forced shutdown module for electric power, the load of the consumer, and an information block connected via bi-directional communication channels of general access with unique identification addresses to a data acquisition and control device and to a switching unit of external devices and through unidirectional communication channels of shared access with unique identification addresses connected to the unit information display and with the I / O panel, while the second output of each specialized counter-calculator of consumed electricity is connected in two a shared communication channel with unique identification addresses with the second input of the corresponding power cut-off module.

The drawing shows a block diagram of the proposed multimedia system of control and management of energy resources.

The multimedia energy monitoring and control system contains, for each energy consumer, a serially connected power electric network 1 _i (i = 1 ÷ n), a specialized counter-calculator of consumed electricity 2 _i , a forced power cut-off module 3 _i and a consumer load 4 _i , as well as a data acquisition and control device 5 connected via a bi-directional shared communication channel with unique identification addresses to the second input of each specialized Rowan counter-calculating consumption power 2 _i, and Workstations based on personal computers 6 and the server 7, the computer-collector 8, a central control room 9 and «n» structurally identical local information-measuring control unit accounting and energy management 10 _i . Each local information-measuring unit for monitoring, accounting and managing energy resources 10 _i is connected via bidirectional communication channels with unique identification addresses to a data acquisition and control device 5 connected via bi-directional communication channels with unique identification addresses to a collecting computer 8, connected via bi-directional shared communication channels with unique identification addresses to workstations based on personal computers 6, to server 7 and to the central control room 9. At the same time, each local information-measuring unit for monitoring, accounting and managing energy resources 10 _i includes a series-connected power electric network 1 _i , a specialized meter-calculator for consumed electricity 2 _i , a forced power cut-off module 3 _i and consumer load 4 _i , as well as information block 11 _i , connected via bi-directional shared communication channels with unique identification addresses to the collection and transmission device data and control 5 and with a switching unit of external devices 12 _i and connected via unidirectional communication channels of general access with unique identification addresses to the information display unit 13 _i and to the input / output panel 14 _i .

The system operates as follows.

In the local information-measuring unit for monitoring, accounting and managing energy resources 10 _{i, a} specialized meter-calculator for consumed electricity 2 _i carries out continuous metering of the electricity consumed by the consumer load 4 _i from the power network 1 _i .

If the payment terms are violated, the central control room 9 through the collecting computer 8, the data collection and transmission device 5 and the specialized counter-calculator of the consumed electric power 2 _i sends a command via a bi-directional communication channel with unique identification addresses to the forced power cut-off module 3 _i to disconnect the consumer load 4 _i from the power network 1 _i . The technical condition of the 3 _i power cut-off module is controlled by a specialized counter-calculator of 2 _i consumed electricity, which guarantees reliable disconnection of the 4 _i consumer load from the 1 _i power network until the debt is paid off.

The central control room 9 sends via bi-directional communication channels with a unique identification address to each information block 11 _i information about the electricity consumed and payments for it, as well as news, additional information, weather information, etc., received in the information display unit 13 _i for later viewing using the remote I / O 14 _i .

The switching unit of external devices 12 _i can be used to connect, for example, measuring transducers of gas flow, cold and hot water, thermal energy, pressure sensors, temperature, fire alarm devices, etc., which can significantly expand the technical capabilities of the system in the field of integrated control, accounting of energy resources, as well as their management.
