sequence of operations, complexity and narrow functionality.

The result achieved by using the inventive automated system is to increase the speed, reliability and expansion of functionality by increasing the amount of non-volatile memory, emergency information retrieval and programming during commissioning and changing the system architecture, the ability to change tariffs depending on the time of day, time adjustment .

The drawing shows a structural diagram of an automated system.

The automated metering system for electricity consumption contains / 01 channels / / 99 1,2 ... /, each of which consists of L / 1, 2, 3 ... / electric sensors, addressing unit 2, which consists of n counters 3, shift register 4 and address selector 5, as well as a hub 6, consisting of a controller 7, a non-volatile 8 unit and an interface 9, and a data collection and control channel 10, consisting of a first transceiver 11, modulators 12 and 13, demodulators 14 and 15, the second transceiver 16, the central hub IV / computer /, the bus wasp 18, data bus 19, shift bus. -:. 20 and resolution bus 21.

The device operates as follows.

From the sensors 1, the shchulsa arrive at the counting inputs of the counters 3, which carry out the counting of pulses and give increments of the values of the consumed electricity in the form of a frequency-W pulse code.

19 data, controller 7 synchronously with the shift signal sends the address of the polled shift register 4. In this case, the Request signal must have level O. All m address selectors 5 receive the transmitted address. After transmitting the address, the controller 7 sets level 1 on the request bus 18. In this case, the address selector 5, for which the set address matches the received one, allows / log 1 on bus 21 and log 1 on bus 18 / to transmit data synchronously with the corresponding shift register signal Shift issued by the controller 7 on the bus 20. Thus, all channels are periodically interrogated. In controller 7, the obtained increments are converted for each meter directly to the readings of the consumed electricity, with the data being recorded in non-volatile data units, broken down by tariffs. 1 time zones. In controller 7, tariffs are recorded depending on the time of day, by switching it to a specific tariff, information is recorded in the corresponding memory box of block 8,

At the request of the central hub 17, the hub 6 provides the necessary. Inerrmation on the 0.38 kV power network using the network transmit-receive device Ontsentor 6 allows interrogating up to 32 addressing units and is intended for installation in the entrance of an apartment building with no more than 128 meters.

The data collection and control channel 10 is intended for transmitting a polling signal from a central concentrator 17 to a corresponding concentrator, as well as for transmitting corresponding data from a local concentrator to a central concentrator. Channel 10 collects information, if necessary, monitors the integrity of any data line, checks for the presence of subscribers in each channel, sets tariffs, enters new data about subscribers, adjusts the time and parameters of the circuit.

The central hub is designed for installation on a transformer substation / transformer substation / or distribution point / RD / and allows you to serve up to 512 meters and monitor the parameters of the consumers' power supply network, fire and burglar control of the transformer substation or switchgear, and switch the corresponding circuits at the dispatcher's signal.

The optical interface 9 is designed for emergency information retrieval and programming during commissioning and changing the architecture of sisters. Information is acquired and programmed by a portable control device.

The system and its software provide the opportunity to increase the volume of non-volatile memory in order to connect gas, hot and cold water, heat sensors to the system. This allows you to conduct comprehensive metering of energy consumption by subscribers.
