The structure of a wireless centralized automated complex for managing engineering equipment of residential and public buildings and apartment metering of energy and water consumption is shown in FIG. 1.

The complex consists of equipment located in residential buildings, and equipment placed in the premises of the information and dispatch center.

The equipment placed in residential buildings consists of radio transmitters with an encoder for transmitting tele-signaling signals (2) from event detectors (3), radio signaling devices for transmitting integrated-signal telemeasurement signals (7), an object telemetry unit (8) connected to a current-value meter (9), an intra-house information network (1), an intercom (10), a matching device (12), and radio equipment that provides communications between residential and public building equipment and the information and control room them center (5).

The equipment located in the premises of the information-dispatch center consists of radio equipment that provides communication between the equipment of the information-dispatch center and the equipment of residential and public buildings (5), a hardware-software complex (6) and communication facilities with the city information network (11).

The information house network consists of a controller, a two-wire address bus for data collection, network radios with a decoding device, and wired interfaces for transmitting tele-signaling signals.

To increase the range of radio communications, a unidirectional radio relay (4) is used.

For home communications, a unidirectional narrowband or broadband radio channel is used.

To collect data on energy and water supply in apartments of residential buildings, radio alarms are used that transmit the integral values of parameter measurements.

A radio signaling device is a device consisting of transducers (sensors), an electronic signal processing unit, a radio transmitter, an autonomous power source, and devices that report operability and unauthorized interference with the operation of the device.

Converters (sensors) in radio signaling devices are electric meters and water flow meters with a reed or electromagnetic sensor, thermocouples and manometers.

The main part of the signaling device is the electronic signal processing unit, which performs the following functions: detects events;

- implements “data compression, minimizing the amount of data transmitted to the transmission level used in fire alarm systems (24 - 32 bits). To minimize the amount of transmitted data on energy and water consumption, the procedure for integrating source data is used;

- assigns “a name to a radio signaling device;

-Includes a radio transmitter for transmission;

controls the performance of internal power supplies;

fixes unauthorized opening of a radio signaling device and violation

operability of converters (sensors);

generates a signal about the presence of radio communication between the radio signaling device and

information dispatch center;

carries out a verification check of the correctness of the transmitted messages.

To transmit the current values of pressure, temperature and mass of cold and hot water from heat regulating centers (SEC) and water measuring devices (VMU) and transmit control signals, an object telemetry unit (8) is used, operating according to an interrogation algorithm.

Data from the controller of the informational home network, data from the object block of television measurements and voice signals from the intercom through the matching device (12) are transmitted to the transceiver (5).

The matching device provides the simultaneous transmission of three digital streams to the transceiver, consisting of speech signals, data from the information house network and data from the object block of television measurements.

For communication between the equipment of residential and public buildings and the equipment of the dispatch center, two narrow-band radio communication channels or digital multi-channel radio communication with Gaussian or phase manipulation with frequency and time separation of signals are used, which provides protection against unintentional and deliberate interference. An example of such communication is communication in accordance with the DECT (Digital Enhanced Cordless Telecommunications) standard.

Using digital multi-channel radio communications to control engineering equipment allows the population to provide additional information services, for example, telephone and the Internet.

According to the data received from radio transmitters, radio signaling devices, the location of objects is determined by wire interfaces and a telemetric channel in the information and dispatch center, events that have occurred are recorded and measured data are presented, as well as violations of the devices' performance and cases of unauthorized interference with their work.

A wireless centralized automated complex can serve as a fire alarm.

The hardware-software complex (6) performs the following functions:

- provides the operator with data on emergency events and monitoring of engineering equipment, indicating the nature of the event, the place of its occurrence and recommendations on the actions of the dispatcher, as well as the protocol for recording events;

displays for the elevator maintenance operator the operating status of the elevator equipment;

- used to control the technical facilities of the complex.

A wireless centralized automated complex allows you to collect information from at least 500,000 sources, monitoring engineering equipment and collecting data on energy and water supply in one hundred residential buildings with five hundred apartments in each house and with ten sources in each apartment. At the same time, the alarm transmission time does not exceed 1 second.

The present utility model can be industrially applied in the urban economy. At the same time, the radio communication of residential and public buildings with the information-dispatch center can be built in accordance with the DECT (Digital Enhanced Cordless Telecommunications) standard.
