State of the art

A known system for wireless automatic meter reading (Eurasian patent EA No. 004163B1, 12/18/2000) having a remote meter reading device on the user side for receiving the meter reading displayed on the display device of the totalizing counter in the form of an image, recognizing the meter reading and transmitting the readings via radio a meter, and a meter reading center for receiving and processing digital code data transmitted by a user meter remote meter reading device la, and transmitting a synchronization code for performing a wireless remote reading operation, the user-side remote meter reading device comprising a sensor element in a predetermined portion of said totalizer for scanning a display device of said counter, the sensor module including a sensor element for of reading an image of a digit displayed on said display device niya, and conversion of the read image into an electrical signal; a module of an optical character reader comprising dynamic random access memory for storing digit image data read by said image sensor, a digital signal processor for performing

operations of preprocessing the image data of the numbers stored in the random access dynamic memory, with the possibility of extracting only the components necessary for recognizing the numbers from them, and the main processor for comparing the data extracted using the digital signal processor with a recognition library stored in an electrically erasable and programmable read-only memory, generating a digital code corresponding to said image of a digit, in accordance with the result of the comparison, and for ominaniya generated digital code in permanent flash memory, and adapted to detect the counter, via the read unit image sensing element; a radio frequency module for transmitting digital code data stored in said flash memory and / or digit code data currently displayed on said display device to a counter reading center for a predetermined period of time and receiving a command from said counter reading center ; and a synchronization time controller for ensuring standby in a normal state and only when the current time corresponds to the synchronization code of the command received by said radio frequency module, supplying power from the power source to the optical symbol reader module and said radio frequency module to minimize power consumption.

The advantage of the system is the ability to remotely read meter readings, convert data to a digital code and use radio communications to transmit data to a read center.

The disadvantages of this system are:

- excessive complexity associated with the conversion of the image of the reporting device of the counter into an electrical signal, as well as using the built-in clock to control the data transfer mode;

- the need to refine previously installed meters.

These shortcomings entail an increase in the cost of the system.

A well-known automated system for transmitting and receiving information on energy consumption (utility model patent No. 50699 U1, 04/18/2005), including primary measuring devices connected to client nodes that are connected via a wire line to input / output devices equipped with information exchange tools with its consumers, and information signal processing tools, as well as information signal processing tools, located in the client nodes. At the same time, electric meters, cold and hot water flow meters, gas meters with a pulsed telemetric output can be used as primary measuring instruments without their modification.

This system has not always used functions, in particular, processing information signals in client nodes with its binding to astronomical time. The integration of customer nodes into a network through wired communication is practically impossible with a significant distance between the measuring devices, for example, in the private residential sector. The system also has an increased cost.

As the closest analogue (prototype) adopted an automated system for transmitting and receiving information on energy consumption according to patent No. 50699.

Utility Model Disclosure

Brief Description of the Drawings

The utility model is illustrated by a drawing (Fig. 1), which shows a block diagram of an automated system for collecting data on energy consumption for a billing period.

Utility Model Implementation

The inventive automated data collection system operates as follows.

Accounting for energy consumption is carried out by primary meters - counters 1 with a pulse output device, each of which produces pulses whose frequency is proportional to the amount of consumed resource. The pulses are fed to the input of the data transmission device 2, in which, using the counter 3 and non-volatile memory 4, the number of pulses is counted and the received data is stored. Node 5 converts the received data into a digital interface. The radio module 6 operates in radio mode until a request is received and after the data transfer is completed.

The data receiving device 7 at a time determined by the operator issues a request to the selected data transmission device 2. Upon receipt

the request, the radio module 6 of the data transmission device switches to the radio transmission mode and transmits the encoded data in memory 4, which the radio module 8 of the data receiving device receives 7. Then, the radio signal is converted by the node 9 into a digital interface, the received data is transmitted to the data storage device - computer 10.

In the absence of direct radio visibility between the data receiving device 2 and the data transmission device 7, it is advisable to perform an additional function - relay data over the air. This is possible by introducing into the data transmission device 2 hardware and software tools that establish a “request-response” mode between several intermediate data transmission devices.

The data transfer device 2 may be self-powered.

The data receiving device 7 may receive power from the computer 10.

The data receiving device 7 may have autonomous power and means for wireless data transmission to the computer 10.

The data transmission device 2 may include a display on which information to the consumer transmitted by the system operator is displayed, about the debt, about the upcoming verification of readings, etc.

The radio module 6 of the data transmission device 2 may include an integrated antenna.

Each data transmission device 2 has a housing and is connected to a corresponding closely installed counter 1 by a wire line.

A pulsed power supply unit with galvanic isolation from the supply network can be placed in the housing of the data transmission device 2.

Such an implementation of an automated system for collecting energy consumption data for a billing period allows:

- carry out remote collection of data on the amount of consumed resources;

- use meters with a pulsed telemetric output without their refinement;

- use radio communications between data transmitting and receiving devices instead of wired electrical communications;

- have a data transmission device with the optimal set of functions necessary for the transmission of data received from electricity meters;

- have a data receiving device with a minimum set of functions necessary for receiving data on energy resources consumed and for entering them into a data storage device;

- use a computer as a data storage device;

- establish the feedback of the system operator with the energy consumer.

All this will help optimize the costs of creating and using an automated system for collecting energy consumption data for the billing period.

The proposed automated system for collecting data on energy consumption for the billing period can be used as a lower level system of an automated information - measuring system for commercial accounting of energy carriers of household consumers.
