The objective of the utility model is to improve the monitoring and control system for energy consumption with the achievement of a technical result, which is expressed in expanding functionality by creating a multi-level monitoring system and expanding the circle of external consumers of real-time information on energy consumption at system objects.

The technical result is achieved by the fact that the monitoring and control system of energy consumption, including facilities with equipment (OO) for primary metering of energy consumption, devices for transmitting information about energy consumed to the server of the data processing center (SCOI) via the Internet, and devices for transmitting information from primary equipment metering at the facilities are combined into a common local wired network RS-485 for all types of resources using a server operating with a console application and the ability to collect and store primary information, configure and manage energy metering equipment and two-way data exchange with the server of the data center, and graphical interfaces for viewing information on energy consumption at system objects in real time by individual consumers and users of the data center, is additionally equipped with interfaces energy suppliers made with the possibility of access to the consumption data of the corresponding energy resources , and client interfaces, while the information is transmitted via TCP / IP with an asymmetric public key encryption algorithm based on the SSL protocol.

In addition, the users of the information processing center can be the administrator, operator, engineer, dispatcher of the situational information processing center, and the clients can be a partnership of homeowners (HOA), a management company (UK), housing and communal services.

At the same time, the administrator’s interface is configured to view and edit the SECI database, access to primary information and create new accounts for operators, engineers, dispatchers, the consumer interface registered in the energy accounting system is configured to view information on their TOE about the consumption history in time and payment, receipt and printing of payment documents, setting power limits, the interface of the energy supplier is configured to access consumption data I have the appropriate energy resources of users, compiling summary reports on the primary data of my users, managing the OO of my consumers and viewing information about losses, the operator interface is configured to create new user accounts of suppliers, suppliers, customers and manually entering primary data into the database, viewing the current and archival information on energy consumption by consumers, generating reports and viewing information on consumption, both of individual consumers and the consumer group , the engineer’s interface is configured to initialize new TOEs in the server system, diagnostics and settings of the latter, the dispatcher’s interface is configured to monitor selected energy consumption indicators, manage the TOE and alert about emergency situations, deviate energy consumption from nominal values, the energy supplier’s interfaces are configured compilation of summary reports on the primary data of its users and the management of the TOE of its consumers, customer interfaces They are able to receive reports on their consumers and suppliers of energy resources, receive and process data on energy consumption from third-party accounting systems and generate xml data for transmission to the latter.

The system includes a software and hardware complex (PAK) for dispatching, consisting of a set of hardware and software tools that work together to control and monitor the consumption of energy resources, for example, in the form of heat energy, electricity, hot and cold water supply, and metering of natural gas consumption.

The hardware includes metering equipment for the consumption of at least one of the energy carriers from the number of electricity, thermal energy, cold water supply, gas and centralized hot water supply.

Equipment for metering energy consumption includes a primary energy meter with an interface or pulse output, a device for collecting and transmitting data to a combined device for collecting and transmitting data (USPD). RTUs are combined into a common local wire network RS-485 for all types of energy through splitters. RTU data is transmitted to the RS 485 address console panel. 4 loops, which, observing the sequence of packets, transmits them over the local network to the RS-485 interface repeater. The latter, amplifying the signal, transmits information to the RS-485 repeater. From the repeater on the local network using the RS-485-USB interface converter, the data passes through the gateway to the OO server. The OO server program operates as a console application that runs in text mode and into which data can be entered from the keyboard. Advantages - compactness, speed and clarity of work, they are conveniently used as "building blocks" for the automation of many routine tasks that do not require interactive user interaction.

The OO server runs in two threads. The first is the processing of messages from the Center, the second is the survey of the OO.

Data is exchanged over the Internet, information is transmitted over TCP / IP with an asymmetric public key encryption algorithm based on SSL. The transmission of control commands is initialized with the SSCI. SECI is the main link of the system. It runs a program that processes incoming information from OO servers.

The OO server only periodically checks to see if a message has arrived from the SECI. Data transfer is initialized by the TOE server itself. In normal mode, the server transmits data every time 10 megabytes of information are accumulated. In case of detection of communication errors with the equipment or in case of accidents, data on them is transmitted immediately. In the absence of communication with the SCOI, a repeated attempt is made to contact him, if it failed, then the data is accumulated on the server of the TOE. Data is stored in files up to 10 megabytes in size. A file is erased only if confirmation of its successful receipt is received from the SSCI. This ensures data integrity. The absence of data loss in practice means the need for continuous verification of the transmitted and received information for integrity. This check is included in the encryption and decryption algorithms of information.

With the help of control commands, the SECI sets or resets the current values and constants on the counters, and changes the specific parameters of the TOE.

The operation of the TOE server is based on the configuration tables transmitted by the SCOI and stored on the TOE server itself. They record the settings of equipment objects, mask requests and control commands. Based on the configuration tables, the OO server sets the settings, determines what, where and in what form to send it, and in what form the answer should come.

The information received by the TOE server, as well as the requests sent to it, are structured in accordance with standard protocols. For each TOE, a choice of its own exchange protocol is possible. In them, data is transmitted in the form of a strictly specified array. In addition to data fields, it includes fields with the device address. Also in the array there are fields with so-called checksums. Checksums are calculated using certain mathematical algorithms based on all other fields and are designed to verify the accuracy of the information received. Typically, checksums are calculated in the process of obtaining the array, and then the obtained and calculated values are compared.

Direct data collection from the TOE is carried out in the process of interrogation of object equipment in a separate stream from the processing of commands of the center. The procedure is initialized when the OO server is running periodically on a timer. Each device has its own polling period (a multiple of the timer period).

When the procedure is called, the OO server passes two structures to it:

- a structure containing the settings of the TOE;

- a structure containing masks for request and response commands. The primary and raw information from the TOE servers is received at the SCI. At this stage, the application running on the server receives data via the TCP protocol and enters the information into the primary database data tables. Further, by means of the database management system (DBMS), the primary data are grouped and aggregated, i.e. indicators for accounting points are updated. This makes it possible to quickly access the desired indicators.

To ensure the functioning of the console application and the accounting system as a whole, certain requirements for the server operating system and platforms for launching applications are provided.

Microsoft Windows XP SP3 / Vista / 7, Linux OpenSuse 11, FreeBSD 8.2, and the MySQL 5 DBMS supporting any of the listed operating systems can be used as an operating system.

After the primary data has passed the processing procedure, they can be extracted from the database for visual display in various forms. An application with a graphical user interface is involved in this process of presenting information. It provides the ability to receive data in a structured form and analyze it. Users can request information of almost any nature and receive it either in tabular, graphical or combined form. There is also the possibility of creating reports in which information is grouped by various parameters.

At the data presentation level, applications with a graphical user interface are run. Users of the system are the administrator, operator and engineer of the information processing center (TSOI), the dispatcher of the situation center, the consumer, the supplier, the HOA, UK, housing and communal services, the integration client. Each user corresponds to a client workstation that supports the necessary functionality, and depending on its type, a certain available set of actions is provided. The administrator can view and edit the entire database of the center. Additionally, access to primary data and user data is provided. Creation of new accounts of operators, engineers, dispatchers is allowed.

A consumer registered in the energy metering system can view information on their metering points, receive and print receipts, view the history of receipts and consumption, set limits on capacity and throughput (if available).

It is also possible to compile detailed reports on your consumption over time.

The energy supplier has access to read its data and the data of its subscribers. It implements the functionality of the "consumer", and also provides the opportunity to compile summary reports on the primary data of its subscribers, manage the facility equipment of its subscribers and view information about losses.

Clients of HOA, UK, housing and communal services are provided with the same opportunities as the "supplier", as well as viewing information on their subscribers and their suppliers. Print your receipts. Getting your reports.

Integration clients can access xml data for transfer to existing energy accounting and monitoring systems. Receiving and processing consumption data from third-party accounting systems.

The TsOI operator is available to create new user accounts, suppliers, customers. It is possible to manually enter the primary data into the database. View current and archived energy metering information for subscribers, generate reports and view consumption information for both individual subscribers and a group of subscribers.

The TsOI engineer has access to the initialization functions in the system of new servers of on-site equipment and metering devices, as well as diagnostics and settings of on-site equipment.

The dispatcher of the situation center has the ability to monitor selected indicators. The ability to manage the TOE, alerts about emergency situations, the deviation of energy consumption from the nominal values.
