Occupied track monitoring system OTMS

OTMS is intended to monitor the freeness of track sections of any complexity and configuration at stations and running lines, with autonomous  or of any kind of electric (AC or DC) locomotive power.

The OTMS works under any (close to zero) resistance of track ballast. The system can also be used at sections with steel sleepers and connecting bars at steel bridges.

OTMS equipment is easy to use and install, has small dimensions and does not have to be seasonal adjusted.

OTMS can be used in a wide variety of railway automation systems:

• monitoring freeness of approach sections of a railroad crossing;
• monitoring block sections of automatic block signaling;
• monitoring switch sections and Arrival-departure tracks at a station;
• monitoring switch and non-switch sections in the automatic switching systems of hump yards;
• monitoring complete train arriving in  Semiautomatic block signaling;
• fixing the passage of car axles in detection system of overheated hotbox;
• positioning the axles of the cars at the weight measuring stations;
• measuring and monitoring speed of rolling stock;
• monitoring filling track sections.

OTMS can be integrated into any existing relay and microprocessor signaling systems in such cases as a new construction, modernization or complete overhauling.

OTMS can monitor track sections of any length and configuration. In it, you can obtain diagnostic information displayed on the Signal maintainer AWP with a suitable interface, for example: the number of axles passed through each a counting control point, taking into account the moving direction; pre-failure state of communication channels with counting control points and so on.

Interfacing with the higher level information signaling systems is performed on modern digital channels: with microprocessor signaling systems - through the digital interface of CAN communication lines; with relay signaling systems - using safety relay.

You can choose several kinds of options of using OTMS where one central module is used for: every 4 monitored track sections (dual-channel system), for every 8 monitored track sections (single-channel system), or not to use the central module at all (it is a subsystem in the microprocessor signaling system). The number of central modules for every construction project is unlimited.

AWP for monitoring and archive of axes account AWP-OMTS

AWP allows you to record the archive, view the current status and the archive of the status of all OMTS devices and train conditions at the station.

Displaying the current state of sensors on the station plan and diagnostic information, pre-failure conditions in real time allows you to quickly eliminate possible damage and increases the availability of the system.

With the help of AWP-OMTS, it is possible to perform artificial release of sections without individual IO buttons on the remote.

ECONOMIC EFFICIENCY OF USING THE SYSTEM

• the system works in any (close to zero) resistance of track ballast, which let significantly reduce the maintaining cost the track and isolated rail joints;
• reducing the cost of equipment sections compared to traditional rail circuits (eliminates the use of expensive copper-containing equipment rail circuits);
• reducing of operating costs, including due to the failure of external relays requiring periodic maintenance in the maintain once;
• increase of an operating availability by diagnosing of potential failures;
• significant cost savings when replacing traditional rail chains due to compatibility with the cable network of rail chains and the lack of the need for new cables and earthwork.
