Operated in conjunction with on-site equipment operating in the “Struna-M” protocol and
"Struna-3M".
Integration into RSPIS “Radioset” is provided.
RSPIS "Struna-M" is developed using
the following principles:
Two-way communication channel
With a small number of objects (up to 160 pieces) and their small distance from CCO, a construction option is possible RSPIS "Struna-M" without the use of repeaters.
The remote control directly receives messages from objects. Reception and
processing is carried out using the monitoring station
"Struna-M" consisting of
the receiving unit (RPr) and the display unit (BI).
using repeaters
When the number of objects or their distance from CCO increases by a distance of more than 6 - 10 km it is necessary to use repeaters (up to 8 pcs).
In this case, the relay receives and processes messages from objects with subsequent transmission to the console via the monitoring station “Struna-M/R”.
Possibility of step-by-step expansion of system capacity, starting from a minimum set by adding groups and repeaters
Increasing the service area when using additional geographically distributed repeaters (up to 8 pcs)
Configuring and controlling the repeater from the remote control
Protection of the repeater from spoofing through the use of a bidirectional communication channel between the repeater and the monitoring station “Struna-M/R”
Reducing the detection time of missing signals and the number of false messages through the use of new processing algorithms and predicting the time of notification reception
Operational analysis of the causes of unstable operation of each object device due to automatic measurement of the level and quality of received messages

In the private security departments of the Federal State Budgetary Institution of the Military District of the Ministry of Internal Affairs of Russia in the Moscow Region, specialists from LLC
"ASB SERVICE" completed construction, installation and commissioning work on the installation of eight
complexes of radio information transmission systems RSPIS "Radioset" produced by LLC NPP "ASB"
"Record".
The introduction into operation of RSPIS "Radioset" made it possible to combine into a single radio network within
30÷50 km previously installed RSPIS “Struna-M”. This made it possible to strengthen CCO and
increase the economic efficiency of equipment operation.
Wide diagnostic capabilities of the equipment (measurement of SWR, input signal level,
interference, radio transmitter powers, uninterruptible power supply parameters, etc.)
increase the operational quality of the system and reduce related costs.
At the beginning of this year, at NPP ASB Record LLC, with the participation of representatives of the Main Military District of the Ministry of Internal Affairs of Russia and the Federal Public Institution
Research Center "Security" of the Ministry of Internal Affairs of Russia carried out standard tests of the repeater "RT-M" version 2 of
composition RSPIS "Struna-M".
This repeater was subjected to standard tests with the participation of representatives of the Main Directorate of Military District of the Ministry of Internal Affairs of Russia
and FKU Research Center "Security" of the Ministry of Internal Affairs of Russia.
Based on the test results, a decision was made on the possibility of using “RT-M” version. 2 in composition
RSPIS "Radioset".
"RT-M" version 2 FIDSH.425664.004 from the radio notification transmission system (RSPIS) "Struna-M"
FIDSH.425624.001 developed by NPP ASB Record LLC
FUNCTIONAL CAPABILITIES RT-M ISP. 2:
• reception, processing and accumulation of notifications from 160 object devices RSPIS “Struna-3”,
"Struna-3M", "Struna-M";
• transmission of notifications to the centralized security console (CCO) via RSPIS “Radioset”;
• generation of an “Accident” notification in the absence of a signal from the facility equipment;
• setting the time for generating the “Accident” notification;
• assessment of the level and quality of the received radio signal from facility devices;
• imitation resistance of the communication channel with the remote control;
• transition to backup reception channels when changing frequencies by the repeater (RT) “Radioset”;
• automatic search for the RT signal “Radioset” when communication with it is lost;
• local and remote diagnostics of the level and quality of reception of the remote control signal;
• local and remote diagnostics of the antenna-feeder path of the repeater;
• automatic adjustment of the power of the radio transmitting device depending on the distance to
RT "Radioset";
• self-protection using 3 built-in alarm loops and a tamper sensor;
monitoring the integrity of the body;
• automatic transition to backup power from the built-in rechargeable battery;
• RT-M isp.2 is operated only in conjunction with RSPIS “Radioset” (this RSPIS must
be previously deployed).
