Embodiments of the invention are described in conjunction with the accompanying drawings, its mechanical driving part, there are the electrical motor D that is loaded in the transmission gearbox 4 and an end of worm reducer 5, wiring roller 6 to link to each other with worm-wheel shaft, one end of steel rope 3 installs on it, the other end is walked around stroke roller 7 and is linked to each other with an end of pin 2, pin 2 hinge fulcrums one side is respectively equipped with collision block pressing limit switch XK-1, SK up and down, under the rail of both sides, distance road junction 50 and 1000 meters pressing pressure point sensor 1XK, 2XK and 3XK, 4XK is housed respectively; Autonomous cruise speed system removes radio receiver and is contained in the train driver cabin, and the remainder circuit card is contained in the automatic control box 1.Described autonomous cruise speed system comprises circuit such as logic control, infrared, reception, decoding, modulation, emission, warning.

Be to realize when the present invention uses, when obstacle being arranged, when (car, thing), by F at road junction place by following program ₁And F ₂The change resonance oscillation circuit of forming produces the 15-35KHZ oscillation frequency, through BG ₁After the amplification, make infrarede emitting diode LED ₁High-frequency signal is launched, and the obstacle that is rested on the road junction goes back infrared reflection, and adoptor DU receives it and one the tunnel through time-delay 5-10 second, energized, and amplify through the IC741 discharge circuit on another road, is transported to audio coding, IC ₂567 input end tripod in the 8th pin output low level, makes BG ₂Saturation conduction is in capacitor C ₈There is the voltage about 8V at two ends, make transmitter circuitry get electric work.Disappear in order to prevent that locomotive from reporting to the police at monitoring section, be provided with memory circuit, work as BG ₂During conducting, phase inverter F ₃Input end is high potential, F ₃Anti-phase back output low level, this feedback procedure can make BG ₂Keep conducting state, thereby not limited by the car body mobile status.By BG ₄, BG ₅Deng the carrier generator of forming, its frequency is by L ₂, C ₉Determine about 30-50MHZ, F ₄, F ₅, F ₆The ON-OFF control circuit of forming, BG ₃Conducting and the mode of operation that ends the may command carrier generator, BG ₃Conducting with end, export a sound signal, its frequency is 1000HZ, this sound signal is coupled to BG ₃Base stage control BG ₃State, modulated CF signal is by coil L ₂Be coupled to L ₁Launch through antenna, be loaded on after radio receiver in the train driver cabin receives this signal, driving alert notice driver road junction has obstacle, takes the emergency brake measure immediately, thereby the accident that prevents takes place;

When right (left side) ranks garage arrives apart from the road junction 1000 meters, pressing pressure point sensor 1XK(3XK) time, the Z contactless switch gets electric and self-locking, its main contact connection motor D is just being changeed and by driving device pin 2 is being put down, after pin 2 is put surely, the collision block pressing limit switch XK-1 that is positioned at pin 2 fulcrum places throws off, Z outage, motor D stall; Meanwhile electric bell rings, alarm lamp DP work (Z disconnects the back and keeps work by XK-2).When the trailer of train arrives the 2XK(4XK at 50 meters of opposite side, road junction) time, BG ₂(BG ₁) upset, through differential, its negative going pulse (through the joint railway carriage passage period of delaying time) makes JK flip-flop be output as 1, if this moment, a left side (right side) ranks car entered, pressing 3XK(1XK) and near the road junction, give another the right of way, then d type flip flop places zero, blocks NAND gate 2(1) BG then ₃End, JZ must not electricity, and pin 2 does not still lift, and all leaves road junction 4XK(2XK until right, left two trains) after just can argue for the sake of arguing and excise electric bell DL and alarm lamp DP; Owing to be provided with logic device in the circuit, thus can guarantee crossing safety, reliably, to the single file road junction or near the road junction, do not give another the right of way, then can be directly with 2XK(4XK) signal delivers to BG ₃, make JZ get reverse contactless switch F of electric starting and self-locking, main contact is connected the motor D counter-rotating and is argued for the sake of arguing, and removes alerting signal (bell, lamp).When arguing for the sake of arguing to certain altitude, collision block pressing limit switch SK makes the F dead electricity, the motor stall, finish one put bar, the working cycle of arguing for the sake of arguing.Time-delay in the logic device is partly set because of payload fluctuates for preventing the pressure point sensor, even therefore a joint railway carriage still can guarantee reliable operation by fluctuation primary line road, back.A left side, situation was similar when the right lateral train passed through the road junction simultaneously, so at BG3 base stage place by or door provide signal, and or the door two input ends be connected on a left side respectively, the pressure point sensor 2XK of pressing when the right lateral train leaves, on the signal path of 4XK, when not having train to pass through at the road junction, automobile, the pedestrian should be able to arbitrarily pass through, though this moment also can shading, but this moment, emitter was not worked, make the power supply of emitter be subjected to the control of travel switch XK-2 for this reason, energized just when pin 2 puts down only, having only has blind to occur at this moment, and then emitter is just worked, and then guarantee safety, reliably, no misoperation.
