(54) REMOTE SYSTEM READING HA MEASURING INSTRUMENTS

Field of technology

The utility model is a system through which the information is converted from a mechanical counter to water flow meters (water meters). gas and other similar devices in an electrical digital signal, then transmitted over a wireless information channel to a telemetry center for remote reading.

The utility model is used in the field of water and gas supply services for household and industrial consumers using flow meters with a mechanical meter.

The utility model allows non-collector metering of flow meters with a mechanical meter, improving the organization and reducing costs and time for metering water or gas consumption.

BACKGROUND OF THE INVENTION

A device for remote digital reading of flowmeters is known [1]. having a similar flow-reading function, but using a flow meter and an electropulse generator whose pulses are a function of the flow rate of the passing fluid. The generated electricity is transmitted by cable at a distance to drive an electromechanical meter.

Disadvantages of this device for remote digital reading of flow meters is that the existing mechanical water meters should be replaced. The cable connection to the electromechanical meter allows the remote measurement to be performed at relatively short distances. It is possible to measure the cost of only one user and there is no possibility to create a system for multiple users.

Another secondary electronic integrating device is known for measuring the amount and flow of fluids [2], using an electromechanical sensor for the flow of passing fluid, the received pulses are converted and amplified by the device and transmitted by wire to an electromechanical counter , in which the consumption of the passed fluid is taken into account by accumulation.

Disadvantages of this secondary electronic integrating device designed to measure the amount and flow of fluids is that the existing mechanical water meters need to be replaced. Remote measurement is performed at relatively short distances. The electromechanical meter allows measuring the consumption of only one user.

Technical essence of the utility model

The system according to the utility model is a network of telemetry server, telecommunication centers and telecommunication measuring devices mounted on users' water meters, each of which registers and converts the reading of a mechanical water meter counter into an electrical digital signal. The utility model periodically reads the readings of the mechanical meters in the water meters through the telecommunication measuring devices. The information is converted, recorded, stored and sent via a telemetry wireless channel to the telemetry server. The telecommunication measuring devices communicate with the telemetry server. Groups of telecommunication measuring devices communicate with the telemetry server through the telecommunication centers. The distances between the telecommunication measuring devices and the telecommunication centers are up to 1500 t. The system, through the exchange of information, monitors and adjusts the telecommunication measuring devices. The telecommunication measuring devices exchange information with the telemetry server and the telecommunication centers only on their own initiative, which is a prerequisite for low energy consumption of the telecommunication measuring devices from the built-in power supply battery, which is the only power source.

The advantages of the utility model are:

- reduction many times the time and costs for reading the readings of water meters at consumers;

- it is possible to read an unlimited number of water meters remotely, without periodic visits of a collector to the users;

- dismantling, installation and replacement of the existing water meters with taps are not necessary

1904 UI chen counter;

- it is possible to remotely set up, monitor and register damage to telecommunication measuring devices and water meters at the users.
