Description

The utility model relates to electrical signal transmission systems and can be used to build automated metering systems for the consumption of energy resources - cold and hot water, gas, electricity, heat.

Currently, the task of automated data collection on the amount of energy consumed by public and industrial facilities is very urgent.

A multi-level system for collecting indicators of consumed energy resources is known, including cold and hot water, gas and electricity meters with a pulsed telemetric output, connected to first-level data collection devices associated with second-level data collection devices, and a system controller (1, 2). The first level data collection devices count the number of pulses received from the counters, store the collected information and transmit it to the second level data collection devices connected to the system controller, which transmits information via a telephone line to a computer or overwrites information on a flexible disk 3, 5 for further processing.

A disadvantage of the known system is the complexity of its organization, due to the two-level hierarchy of data collection devices, which, ultimately, reduces the reliability of the system. In addition, in the data collection devices there is no means of monitoring the integrity of communication lines with meters and the health of the latter, and means of visual display of information on energy consumption.

As a prototype of the claimed technical solution, an automated system was selected for transmitting and receiving information about the state of monitored objects, containing primary measuring devices connected to client nodes, whose functions include collecting, pre-processing and storing information from primary measuring devices, monitoring the integrity of lines communication with meters and the health of meters and the transfer of information to input / output devices - either directly or through the appropriate other information transfer nodes. An input-output device equipped with a computer accumulates, processes, and transfers information to its consumers, including to the system’s control and management unit via a radio channel, wire communication lines, or a telephone line through a modem. The control node (for example, a remote information collection point) manages the operation of the system as a whole, accumulates and analyzes the information received and / or presents the results to information consumers. The registrars communicate with the input-output device via a wire line (3).

The known system has the following disadvantages. In client nodes, only preliminary processing of the information signal is performed, and subsequent processing is carried out in input-output devices. This eliminates the possibility of direct transmission of the information signal from the client nodes through the input-output device to the control node without additional processing, complicates the system and limits its functionality. In addition, connecting client nodes to input / output devices via wire lines without using any means of amplifying the transmitted signals limits the maximum possible number of the nodes mentioned that can be used in the system.

Another disadvantage of the known system is that the client nodes are not adapted to transmit information from primary measuring instruments having a digital output, which also limits its functionality.

The task solved by the utility model is to simplify the system, expand its functionality and increase the efficiency of control over energy consumption.

This problem is solved by the fact that in an automated system for transmitting and receiving information on energy consumption, including primary measuring devices connected to client nodes, which are connected via a wire line with input / output devices equipped with means for exchanging information with its consumers and containing processing tools information signals, means for processing information signals are located in the nodes of the client.

As primary measuring instruments, electricity meters, cold and hot water meters, gas meters with a pulsed telemetric output can be used, in this case, meter counters are used as client nodes. In addition, energy meters with a digital output can be used as primary measuring instruments. In the wired line between the client nodes and input / output devices, relay amplifiers are located.

The utility model is illustrated in the drawing. Figure 1 shows a block diagram of an automated system for transmitting and receiving information about the consumption of energy resources.

An automated system for transmitting and receiving energy consumption information includes nodes of client 1, each of which is connected to primary measuring devices 2. The nodes of client 1 are connected to network 3 by means of a wire line 4, in which

repeater amplifiers 5, which serve to enhance the transmitted signal and contribute to the potential increase in the number of client nodes 1. The means by which the elements of the network 3 exchange information with its consumers are made in the form of an adapter 6 with a computer 7 located directly at the consumer (for example, house), and an adapter and one of the communication devices connecting the network 3 to the remote control station 8, having the corresponding communication device 9 and the central computer 10. The communication of the network 3 with the control room 7 can It can be implemented in several ways:

- via a GSM modem through an adapter 11 and a GSM modem 12; the communication device 10 in the control room 8 is also implemented as a GSM modem;

- through a telephone line through an adapter 13 and a modem 14; the communication device 10 is implemented as a telephone modem;

- using Ethernet technology through adapter 15 and gateway 16; communication device 10 is a network card;

- through the adapter 17 and the radio modem 18; the communication device 10 is in the form of a radio modem.

If the primary measuring devices 2 are electric meters, cold and hot water meters, gas meters with a pulsed telemetric output, meter counters are used as nodes of client 1. If the primary measuring devices 2 are energy meters with a digital output (for example, heat or electricity meters), then they themselves act as customer nodes.

Counter-recorders are secondary devices that have their own unique address stored in the non-volatile memory of the counter, means for processing and storing information about energy consumption with reference to astronomical time, means for

transmitting information in a “request-response” mode in digital format to external devices, means for monitoring the integrity of communication lines with meters and their operability, and an integrated power source that allows you to register information about energy consumption in the absence of power in the network. Up to ten primary measuring instruments are connected to one counter-recorder.

The inventive automated system operates as follows. The beginning of work is initiated either by computer 7 or by computer 10, forming a request sent to the 1st node of client 1 and containing the address of this node. After receiving the request, the client node, the address of which coincides with the address contained in the request, starts transmitting energy consumption data stored in its memory. Then, computer 7 (10) repeats the polling procedure for the j-th node, etc. Thus, a sequential poll of the client nodes (counter-recorders and adapters) included in the system occurs. If necessary, a survey can be carried out not of the entire system, but only of one selected client node.

The advantages of the proposed system compared to the prototype are as follows.

Processing the information signal from the primary measuring devices occurs at the client nodes. There is no need for subsequent signal processing in input-output devices, which allows us to simplify them and expand the functionality of the system as a whole. The use of repeater amplifiers can significantly increase the number of connected energy meters, which, accordingly, expands the capabilities of the system and makes it more universal.
