Description

The utility model relates to energy, electrical engineering, to information transmission and processing systems, to electricity metering devices, to automated control and management systems, and can be used for electricity metering in housing and communal services, in automated control systems and management in the distribution of electricity.

Known Structure of an automated system for metering energy consumption in housing and communal services. RF patent №51255 IPC G06F 17/40. The system provides for the collection of information from primary metering devices to computer meters using a bus interface, and through the device, the collection, transmission and storage of information is transmitted over the air using radio modems to the management company. The disadvantage of this system is the impossibility of using it to control the distribution of electricity, as well as the need to lay the bus interface, as well as communication lines with primary metering devices.

A device is known for automatic metering and control of electricity consumption in enterprises, which consists of an electric energy meter, pulse shaper, daily energy pulse counter, digital-to-analog converter, monthly consumption meters, a unit for setting consumption limits, an indication and alarm unit, a synchronous reversible counter and an emergency unit food (USSR Author's Certificate No. 1626158, GOIR 11/56). The disadvantage of this device is the inability to use it to control the distribution of electricity, as well as the need for laying communication lines between metering devices and control devices.

The closest solution to the proposed one is the Automated information-measuring system of accounting, control and management of energy resources in the housing and communal services, RF patent No. 78966 IPC G06F 17/40. The system consists of primary metering devices with signal converters from them, communication lines with counting computers, connected to the network using the bus interface. Further, information through data acquisition, transmission and storage devices is transmitted via interface communication to the data center of the housing department, where workstations are installed on the basis of a personal computer at each workstation, integrated into a local computer network, and using the appropriate software perform processing, control , accounting, analysis of consumption. The system is equipped with modules for forced shutdown of the energy supply.

However, the described Automated information-measuring system of accounting, control and management of energy resources in housing and communal services has the following disadvantages:

wired installation or the organization of new wireless communication lines and power lines between the individual nodes of the system is required. The use of PLC technology (power line communications) for these purposes is not always possible due to the fact that power lines are not everywhere,

the system allows you to only disconnect consumers from electricity (when exceeding the consumption limit or an emergency), for example, using the meter of the MZEP plant SOE 55/60-T-217 with an integrated electromechanical relay. However, it is often required to simply disconnect the consumer from the electric power, and it is necessary to switch to the backup power line.

In some cases, a fire alarm system (OPS) already exists at the housing and utilities facilities. The most modern and reliable are based on wireless technologies, and include sensors (security and fire detectors), actuators, control panels, radio expanders, etc. Communication between devices in such OPS systems is carried out via wireless (radio channel) networks. See, for example, http://www.argus-spectr.ru/index.php?path=ru/node/4/catalog/190, http://www.argus-spectr.ru/index.php?path = ru / node / 4 / catalog / 326. Using the same wireless technologies, an automated data acquisition system (ASDS) can be built from metering and resource management in housing and communal services.

The technical task of the proposed solution is to provide control of the supply of electricity to consumers using wireless lines.

This problem is solved in that an actuator comprising a transceiver connected via a radio antenna to an automated system, and in series with a microcontroller, a contactor control unit connected to a contactor to control the supply of electrical energy to consumers, while normally-closed switching contacts are designed to communicate with the main line power supply, and normally open switching contacts of the contactor are designed to communicate with the backup power line.

The essence of the utility model is illustrated in the drawing, where

FIG. 1 is a block diagram of an actuator,

FIG. 2 is a structural diagram of an automated system with an actuator.

The actuator is connected to the ASDD via a radio channel, contains an antenna (1) and a transceiver (2), which is connected in series with a microcontroller (3) that provides information processing. The microcontroller (3) is connected to the control unit (4) of the contactor (5) having switching contacts (6), designed to control the transmission of information in the power supply system of consumers. A microcontroller (3) serves to process the information exchanged between an actuator and an ASDD. The contactor control unit (4) connected to the microcontroller (3) serves to control the contactor (5) having switching contacts (6), designed to control the supply of electricity to consumers. Through normally closed switching contacts of the contactor, the consumer is connected to the main power line. A backup power line is connected to the normally open switching contacts of the contactor.

In the block diagram of the automated system (Fig. 2), actuators 7, 8 are shown — object modems associated with electricity metering devices 9, all connected by a wireless radio channel network 10, 11-hub, through an IP connection connected to the reception and control point of the electricity supplier.

The actuator (7) is connected to the consumer's power line, the electricity meter (9) and the associated object modem (8), which is connected via a wireless (radio channel) network (10) to a hub (11), are connected to the same line. The hub (11) is connected via an IP connection (12) to the control panel of the electricity supplier (13).

The actuator operates as follows.

Actuator (7) is connected to consumer power lines, an electricity meter (9) is connected to the same line. Information from electricity meters (9) is transmitted via an object modem (8) via a wireless (radio channel) network (10) to a hub (11), which is used to collect and process information on energy consumption of all consumers and convert this information into a convenient one for transmission view over the IP connection (12) to the control panel of the electricity supplier (13). In the event of an accident on the main power supply line of the consumer (see Fig. 1), information about this event is transmitted from the meter (9) via the object modem (8) via a wireless (radio channel) network (10) to the hub (11), where the primary processing information about this event and generating a control signal transmitted over a wireless (radio channel) network (10) to an actuator (7). The actuator (7), through the antenna (1) receives the control signal through the transceiver (2), which is sent to the microcontroller (3) for processing. The microcontroller generates a control signal for the contactor control unit (4), which activates the contactor (5), as a result of which the consumer is disconnected from the main power line in an emergency condition, normally closed switching contacts of the contactor (6) are opened, and the backup line consumer is connected power supply, normally open switching contacts of the contactor (6) are closed.

It is also possible to control the supply of electricity to consumers without a backup power line. In this case, nothing is connected to the normally open switching contacts (6) of the contactor. In the event of an accident, or when the set limit for electricity consumption is exceeded, on the command from the ACSD, the actuator activates the contactor (5), as a result of which the consumer will disconnect from the main power line.

Thus, the function of controlling the supply of electricity to consumers is implemented (switching to a backup power supply line of consumers or turning off the power supply to consumers in the event of an accident, or when exceeding the established limits for electricity consumption).
