    The frequency of accidents to trains is reduced by providing a self-propelled forerunner which, under control from the train can run on the track ahead of the train. The forerunner is provided with a sensor system for surveying the track over which it is running and with means for transmitting to the train information on the track conditions so sensed. The information may be displayed to the driver of the train and/or fed into an automatic controller for the train. In one embodiment of the invention, signals generated by the sensor system of the forerunner are compared with signals corresponding to the normal condition of the track as stored in a computer.

    Train 1 moves in the wake of leader 2 and can control leader 2 by transmitting signals to the leader through a remote control system. Leader 2, which may be a trolley, has a sensor system for detecting and observing road conditions in front of it, namely, microaudiometric sound sensor 3, air temperature sensor 4, gas content sensor 5, humidity sensor 6, sensor 7 tilt and collision, the vibration sensor 8 and the camera 9, as well as the controllable unit 10 of settings, to the control input of which a path marker is connected, which has receiving elements 12 and 13 of the signal converters 14-17, and a path sensor 18 on the way, with a block of 10 hours through converter 19 and


    the encoder 20 is connected to the information signal transmitter 21, and to the converter 19, a control signal receiver 23 is connected to the converter 19 via the controller 24, with which the operation unit 25 is connected, to the drive unit 26.
    On the leader there are memory devices 27 and 28. In the cockpit of the train control, the information signal receiver 29 is installed, the decoder
    30 information signal through the signal converter 31, associated with the controller 32 of the drive unit to which the drive unit is connected
    33 and an operating unit 34, with the detector 30 connected to the decoder 30, made in the form of a television monitor, and to the converter
    31 is connected via encoder 36 to control signal transmitter 37.
    Transmitters and receivers can be made in the form of a transmitter 38 and a receiver 39 of infrared radiation (Fig. 3), a sound signal (Fig. 4), a radio signal (Fig 5), a sound signal (Fig. 6), a frequency signal transmitted by rail lines (Fig.7),
    The microaudiometric sound sensor has a sensing element 40, adjustable resistors 41 and 42, an amplifier 43, and a tilt and collision sensor has a vessel 44 filled with mercury 45 and two electrodes 46, while the vibration sensor mounted on the leader has springs 48 is a mass 49 and mass transfer sensors 50 relative to the base mounted between the mass 49 and the base, which are connected to a displacement signal generator 51 connected to a signal converter 52 connected to a transmitter 21. There is a vibration playback unit mounted in the control cabin seat 53 and containing cylinders 54j whose rods are connected to a drive 55 to which a pressure source 56 is connected, and the supply circuit of the drive 55 is connected to a converter 31 for communication with a receiver 29.
    A television receiver 57 can be installed on the train, and a television camera 58 and an audio attenuator 59 with an output amplifier connected to a television speaker 60, which is connected to television antennas 63 via amplifier 61 and switch 62 UHF and HF, can be mounted on the leader. .
    When train 1 moves on rails the leader is in front of it. The leader may slow down or accelerate in accordance with the signals transmitted from train 1 by the control signal transmitter 37. Due to the 2 sensors installed on the leader 3-8, the leader 2 can detect and observe the road conditions. As a result of this review, the signals received by the receiver 29 are transmitted back to the train control cabin and the driver receives information that allows timely warning of danger Fig 2)
    The train can be of any type, for example, with a diesel engine, steam, electric, compressed air, magnetic cushion, or li15
    a linear motor running on rails or guided along a canal, or a suspended type electric train.
    By transmitting a signal from the train and acting on the drive unit 26 through the controller 24, the train driver can slow down or speed up the movement of the leader 2 or set the selected speed of the leader 2,
    At the same time, a receiver 29 mounted on train 1 is used for
    35
    receiving signals transmitted from leader 2, obtained from the review and detection of road conditions on and in front of the leader. These signals can be converted to an image on the screen by a level-identifying system of a left-side camera 35 located. Temperature sensor 4 can be used on receiving elements 12 and 13. The output signal from receiving elements 12 and 13 through converters 14-1 is dusted into setting unit 11 for removal memorized parameters, which arrive at the setpoint block 10, in which the corresponding parameter is chosen, compared with the parameters taken from the path, and if the result of the comparison is unusual, the signal is strewed onto the transmitter 21,
    Sound sensor 3 is mounted on a sha or driving axle with a sound, electrical microaudiometric and
    in the control cabin of the train, in which case the driver observes for the information on the screen, or the signal data is entered into the controller 32 for mutual supervision. Then the train. can urgently brake or control leader 2 so as to respond to emergency conditions,
    On leader 2, in the setting unit of 11 parameters, information is stored on the conditions of each section of the road, for example, on the degree of vibration when the train passes over the bridge, on normal acoustic characteristics for comparison with actual road conditions.
    The driver must be warned about any abnormal deviations from
    H
    1524802
    memorized to give him the opportunity to respond to road conditions. The programs of each track section can be activated synchronously using sensors 18 located along the road, which feed the programmed information to the leader. Sensors 18 can be
    installed on each section of the railway or to the side of it, or above it, and can transmit information via electro-optical, electromagnetic or commonly used pre-installed electronic signals.
    The railway is subdivided into sections, and a detecting device, a track sensor 18, is installed at each section. At the separation point between the sections, a sensor 18 is provided with an optical, electromagnetic, electrical or electromechanical switch.
    type to provide a signal
    identifying the level of the systems. The temperature sensor 4 can use the receiving elements 12 and 13. The output signal from the receiving elements 12 and 13 through the converters 14-17 is strewed into the setpoint 11 to extract the stored parameters, which are fed to the setpoint block 10, in which the appropriate setting is selected is compared with parameters taken from the path, and if the result of the comparison is unusual, the signal sprinkles onto the transmitter 21,
    Sound sensor 3 is mounted on a chassis or drive axle with sound, electric microaudiometric and

    Yawn conventional thermoelectric detection system to signal to block 10 a signal from which, at too high or too low temperature, the signal enters transmitter 21, gas content sensor 5 can be installed in front of the locomotive to detect, for example, carbon monoxide or gas. If the leader passes through a tunnel or mineral caves and there is an increased gas concentration, the signal from the setpoint block 10 is also fed to the transmitter 21,
    The humidity sensor 6 is installed under the leader chassis at a selected distance from the railroad surface and has an electrode. When on
    15
    20
    there is water in the railway track or in the tunnel and its level is high enough to be dangerous, the electrode comes into contact with water and transmits a signal to the transmitter 21. The tilt and collision sensor 7 has a vessel 44 filled with mercury and alectrodes 46, Both electrodes are closed through mercury. If the vessel tilts when the leader tilts or the moving leader suddenly changes speed, the mercury moves and the electrical contact between the electrodes 46 is broken. If the leader is knocked over, the electrical contact is also broken, since the electrodes above the liquid level are isolated. Sensor 7 responds: a signal when the railway track has an abnormal incline, or if the leader has flipped or collided with another object.
    Leader 2 can be controlled remotely from train 1 either manually by the machinist, or both, for reliability. In addition, an automatic coupling can be provided for the leader and the train, so when the leader is defective or an emergency situation occurs, the leader and the train can be towed by another locomotive.
    A television camera 58 mounted on the leader, associated with the television antenna 63, enables the train driver 1 to see road conditions ahead on the television screen of the television receiver 57 and thus take the necessary measures in the event of an emergency.
