Proposed group of inventions is designed for traffic control, particularly for checking relative distance between participants of railway transport system to prevent emergencies, including those threatening life and health of people, mainly, maintenance men. According to proposed method, coded signals including codes of radiator identifiers are transmitted by radiators, said signals are received and processed and movement of mobile objects in rail track area, namely, mainteancemen and/or rolling stock, is tracked. Reception of each signal is effected by device mounted on corresponding mobile object which transforms said coded signals into radio signals and transmits then to access points where said radio signals are re-transmitted to other mobile objects. |

Single-mission electronic-mechanical sealing device Single-mission electronic-mechanical sealing device includes bolt for screwing into important part, body in form of a barrel with end surfaces and through aperture for bolt, electronic mark with electronic boards, mounted inside the barrel. Device has base and radio-transparent lid, while base is made in form of flat frame, on upper surface of which electronic mark is mounted, covered by radio-transparent lid. Lower surface of frame is made with at least two legs, perpendicular to lower surface, on ends of which hooks are present, for example, in form of gaggers. In end surface of barrel, through apertures are made with response hooks for interaction with, for example, gaggers of legs of base during mounting of the latter, while inside the body of at least one leg a wire loop with radio element is positioned, connected to electronic boards of electronic mark and being a part of its electric circuit. |

Invention relates to methods of measuring parameters of running of rail trains and to measuring facilities, namely, to float-type compensated pendulum accelerometers with discrete output. According to proposed method, float-type pendulum accelerometer is installed on movable base and axis of sensitivity of accelerometer is aligned with direction of running, and output axis is set vertically, and then float-type suspension of sensing element of hydrostatic type is formed using zero floatability of sensing element. Discrete output signal of float-type pendulum accelerometer is formed and said signal is integrated and signal indicating value of movement of train is obtained. Moreover, output signal of accelerometer at movements of train at slopes and upgrades is corrected. |
