sequence of operations, complexity and narrow functionality.

The result achieved through the use of the inventive automated system.sh is to increase the speed, reliability and expansion of functionality by increasing the volume of non-volatile payetti, 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 electricity consumption metering system contains / 77 channels // g 1, 2 ... /, each of which consists of / / 1, 2, 3 ... / electric sensors, addressing unit 2, which consists of / 7 counters 3 , shift register 4 and address selector 5, as well as a hub 6, consisting of a controller 7, a non-volatile unit 8 and an ethernet 9, and a data acquisition and control channel 10, consisting of a first transceiver 11, a second transceiver device 12, a central hub 13 / computer /, a request bus 14, a data bus 15, a shift bus and 16 and 17 permit bus.

The device operates as follows.

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

Controller 7 with a period not exceeding the overflow of counters 3, rewrites the information in the shift register 4 on the request bus 14 when the pulse goes from 1 to O. On the data bus 15, the controller 7 synchronously sends the address of the polled shift register 4 as a signal. In this The request signal should smolder level A. All // address selectors 5 receive the transmitted address. After the address is transmitted, the controller 7 sets level 1 on the request bus 14. In this case, the address selector 5, for which the set address matches the received one, allows / log 1 on bus 17 and log 1 on bus 14 / to output data to the corresponding shift register synchronously with signal Shift, issued by the controller 7 on the bus 16. Thus, all channels are periodically interrogated. In controller 7, the obtained increments for each neuverenly meter are converted directly to the readings of the consumed electricity with the data entered in non-volatile with a breakdown into tariff zones and 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 cell of block 8.

At the request of the central hub 13, the hub 6 provides the necessary. information on the radio channel using the radio channel receiving and transmitting device .. Concentrator 6 allows you to interrogate up to 32 addressing units and is intended for installation in the entrance of an apartment building sewing no more than 128 meters.

The data collection and control channel 10 is intended for transmitting a polling signal from a central concentrator 13 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 (| s, enters new data about subscribers, adjusts the time and parameters of the circuit.

The central concentrator is designed for installation on a transformer substation / TD / or distribution point / RB / and allows you to serve up to 512 meters and monitor the parameters of the consumers' electrical network, fire and burglar control of the premises of a TP or RP, and switch the corresponding circuits at the signal of the dispatcher.

The optical interface 9 is designed for emergency information retrieval and programming during commissioning and changing the system architecture. Information is acquired and programmed / carried out by a portable control unit.

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