Abstract

The invention relates to control systems and is directed at defining the state of transportation means (TM) in normal and extreme conditions. Each TM is fitted with a power-on radio beacon station (RB) whose signals are retransmitted by means of geostationary Artificial Earth Satellites (AES) of the integrated variety to mated ground stations for reception of information. In extreme situations of TM, the transmission of information from RB is carried out continuously by signal sets with a gap of up to 1 within the narrow band in a wave-range of 400 MH_z which is provided for transmitting emergency signals with the aid of AES. In the normal conditions, signal transmission is carried out in a narrow adjacent band with intervals between sets of greater than 10 sec. An 20-30-fold increase of a transfer bandwidth of the system is ensured by means of a synchronous transmission of the information sets from RB one after another with small time gaps. Synchronism is obtained by means of accurate time marks emitted by RB receivers from navigation systems of the earth satellites of GPS and/or GLONASS.

Claims

1. A system for automatic global monitoring of transport vehicles under normal and extreme conditions, the system comprising a plurality of transport vehicles each comprising a radio beacon device for transmitting signals to ground data collecting centers via geostationary satellites, the radio beacon device being constantly operational during the vehicle'"'"'s movement and stopovers, wherein under the extreme conditions, the radio beacon device continuously transmits emergency data batches with less than one second intervals in a narrow bandwidth of 400 MHz range, dedicated to space retransmission of distress signals, and, under normal conditions, the radio beacon device transmits monitoring data batches in a neighboring frequency band with intervals between batches greater than 10 seconds, wherein the emergency and monitoring data batches are retransmitted via the geostationary satellites to the associated ground data collecting centers.

2. The system according to claim 1, wherein under normal conditions, the monitoring data batches are transmitted from the radio beacon devices installed in various kinds of transport vehicles operating in the same radio channel in synchronous mode with intervals up to 0.1 seconds, and synchronization is based on global time notches up to 0.5 milliseconds detected by the radio beacon from navigational signals of GPS or GLONASS satellite systems.

3. A radio beacon device installed in a transport vehicle for monitoring the transport vehicle under normal and extreme conditions via a global monitoring system including a plurality of ground data collecting centers and a plurality of geostationary satellites, the radio beacon device comprising a transmitter for transmitting signals to the ground data collecting centers via geostationary satellites, the radio beacon device being constantly operational during the transport vehicle'"'"'s movement and stopovers, wherein under the extreme conditions, the transmitter continuously transmits emergency data batches with less than one second intervals in a narrow bandwidth of 400 MHz range, dedicated to space retransmission of distress signals, and, under normal conditions, the transmitter transmits monitoring data batches in a neighboring frequency band with intervals between batches greater than 10 seconds.

4. The radio beacon device according to claim 3, further comprising a navigational receiver for receiving navigational signals from at least one of a GPS satellite system and a GLONASS satellite system, wherein under normal conditions, the transmitter transmits the monitoring data batches in a synchronous mode with intervals up to 0.1 seconds, and synchronization is based on global time notches of the navigational signals from at least one of the GPS and GLONASS satellite systems.

5. The radio beacon device according to claim 3, wherein the emergency and monitoring data batches include data indicating a location of the transport vehicle and identifying the transport vehicle.
