LPWAN technology of VAVIOT the Wireless system of the automated collecting of meter readings of water

Many citizens, desires to save, resort to different methods of decrease in indicators of counters. However in 2016 the Ministry of Construction and Housing and Communal Services concentrated the activity on this problem. If when checking the metering device executive bodies of municipal services find a magnet, then the statement of administrative offense will be drawn up. The code of offenses treats use of magnetic devices as causing property damage. From the offender the penalty in a tenfold size on average regulations of water consumption from that amount for which he managed to deceive the state will be withdrawn.

There are several options of capture of the violator:

• Check. The easiest way to make sure of a counter stop – to visually see a magnet on the counter. But in practice to confirm this aspect it will not turn out in any way, remembering the right to inviolability of housing, offenders will not let in the apartment of staff of public services. In that case check will need to be made repeatedly, only already together with law enforcement agencies.
• Teslameter. If the unfair citizen, letting in the apartment of employees, managed to remove a magnet, the fact of a stop can be checked the special device. The principle of operation of the teslameter is based on residual magnetization of the counter which was not exposed to a stop. But also this method of detection of a magnet has minuses. The first is the cost of the teslameter which fluctuates within 30 thousand rubles. Not each ZhEK will be able to afford such equipment. The second – besides, the procedure of check will take place only if checking gets to the apartment with the consent of living.
• Anti-magnetic sealing. In the presence of suspicions, executive bodies of municipal services can install an anti-magnetic seal on the counter. It signals about attempt to stop the counter a magnet, changing the color. Minus is that in network there is a huge number of methods of deception of a seal. Besides such seals in open access are on sale on the Internet.
• Built-in radio module. The sensor fastens in construction of the counter. Works in a standalone mode. As a result of attempt to stop the counter or to put the sensor out of action, it will send warning to municipal service.

The last method the VAVIOT company applies waters in the counters. The convenience is that all procedure of removal of indications and sending them in relevant organs of municipal services are automated and autonomous. For sending indications the radio module "VAVIOT" which, besides, and is equipped with function of detection of application of a magnet is used. At intervention in operation of the counter of water in a personal account the instant notification with the recorded number of the apartment and time of attempt to stop the counter that will allow to take operational measures will arrive.

"VAVIOT" — the wireless technology of communication for Internet of Things using energy efficient approach of LPWAN (Low-power Wide-area Network). Is suitable for transfer of small amount of data — up to 255 bytes, from hundreds of thousands of different sensors on distance of 50 km on a radio channel.

How does "VAVIOT" work?

The approach used for data transmission in VAVIOT network is very similar to the principle of work of cellular networks.

VAVIOT devices transfer indications to a personal account of the client through the base station where they are processed and provided in a user-friendly type. The reverse channel allows to manage separate devices far off.

However, unlike technology of mobile communication, "VAVIOT" uses the energy efficient radio protocol that allows to transfer data to distances to 50 km and to provide autonomy of operation of devices over 10 years without external power supply.

Advantages of VAVIOT technology

10 years of operation of devices from the built-in battery - Without wires and an external power supply

Devices and VAVIOT modems do not require connection to the power supply network. They are not exacting to a power supply at all. Process of sending data is optimized, and the transmission power 80 times lower, than at the mobile phone. For this reason one power source lasts for 10 years of operation of the device.

50 km — sending range - Without the intermediate equipment and without loss

"VAVIOT" "star" uses topology and provides data transmission on a long distance in difficult city conditions. The signal from the modem arrives on several base stations at once. At the same time walls and constructions are not a serious barrier to a signal.

VAVIOT devices

VAVIOT devices are different metering devices and sensors with the integrated radio module. These are the solutions ready to net surfing of "VAVIOT" developed by us in the most different industries.

They give the measured parameters with the set frequency and have a possibility of remote control. For example, the counter of electricity "Ampere-1" hourly transfers indications to the panel of the manager. And the manager can configure remotely the counter and even to limit its loading.

Base station of "VAVIOT"

The VAVIOT radio station performs data reception from hundreds of thousands of modems and provides a covering to 10 km in the difficult urban environment and 50 km on the open area without noises for a signal of end devices.

The station is easily mounted on objects and has the low cost of service. Works with the broad range of temperatures, it is checked for water tightness and a pyleustoychivost according to IP67 standard.

Cloud platform "VAVIOT. Online"

All data are available in a personal account of the user. Access to it is possible from any place in the world from any device connected to the Internet.

The platform has the flexible configured interface with a possibility of unloading of statistics in Excel and integration with the used information 1C systems.
