Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is the embodiment of the utility model provides a composition schematic diagram of double track people parking lot interval signal shutting audible-visual alarm system, fig. 2 is the embodiment of the utility model provides a pair of double track people parking lot interval signal shutting audible-visual alarm system installation schematic diagram, below combine fig. 1 and fig. 2 to carry out detailed description to the double track people parking lot interval signal shutting audible-visual alarm system who provides of this application.

As shown in fig. 1 and fig. 2, the signal blocking acousto-optic alarm system for a double-track passenger car yard zone provided by the embodiment includes a triggering module 1, a signal receiving module 2, an alarm module 3, and a power module 4.

Specifically, the trigger module 1 is configured to issue a trigger signal. The triggering mode generally includes automatic wireless remote control triggering, manual wireless remote control triggering and voice remote control triggering, and according to the difference of the triggering mode, the triggering module 1 in the embodiment of the present application is an automatic wireless remote control transmitter, a manual wireless remote control transmitter or a voice control receiver.

For automatic wireless remote control triggering, the automatic wireless remote control transmitter is arranged at a proper position in a cab and is always in a transmitting state, and the transmitting intensity is adjusted according to actual conditions so as to adapt to the safe distance for triggering alarm. When the locomotive reaches the triggering position, the strength of the transmitter just can trigger the signal receiving module 2 and enable the alarm module 3 to start working. After the locomotive is driven out of the safe distance, the alarm module 3 stops working and returns to normal. In addition, in order to ensure that the emitter can work normally and stably, a power supply needs to be led out from the locomotive to supply power for the emitter.

For manual wireless remote control triggering, a locomotive driver distributes a manual wireless remote control transmitter, and when the locomotive reaches a triggering position, the driver operates to transmit a triggering signal so as to enable the alarm module 3 to start working. After the set working time, the alarm module 3 stops working and returns to normal.

For the sound remote control triggering, when the locomotive reaches a triggering position, a driver operates to turn on a siren or a horn, and the sound intensity can just trigger a sound control receiver installed in a double-rail yard, so that the alarm module 3 starts to work. After the set working time, the alarm module 3 stops working and returns to normal. In addition, in order to ensure that the alarm can work normally and stably, the sound intensity of the locomotive siren or loudspeaker at the triggering distance must be greater than the ambient noise intensity around the alarm.

The signal receiving module 2 is installed at one end of the double-track parking lot and used for receiving the trigger signal and converting the trigger signal into an instruction signal. Under standby state, the output node of the control relay in the signal receiver is in a normally open state, after the signal receiving module 2 receives the wireless trigger signal with the same transmitting frequency, oscillation frequency and address code, the wireless trigger signal is processed by an internal logic circuit to output an instruction signal, so that the control relay in the signal receiver acts, the state of the output node is converted from normally open to normally closed, and meanwhile, the instruction signal triggers the alarm module 3 connected with the signal receiver to work. After the wireless trigger signal is weakened or disappears, the signal receiver is restored to the standby state after a certain time of delay, the control relay is released, the output node is normally closed and is converted into the off state, and the alarm module 3 stops working.

And the alarm modules 3 are arranged at two ends of the double-track passenger car yard and used for receiving the instruction signals and sending out alarm signals according to the instruction signals. And signal locking between the underground double-track vehicle field areas is realized by connecting two groups of alarm modules 3 in series and synchronously triggering. And a group of alarm modules 3 are respectively arranged at two ends of the double-people parking lot. The double-track man power line is a four-core cable, the red and blue lines are power lines, and the white and black lines are trigger lines. Two groups of alarm power lines (red and blue lines) are connected in series, and trigger lines (white and black lines) are led out from one group of alarms to trigger points in the alarms at the other end of the parking lot, so that the two groups of alarms are controlled in a linkage mode.

The alarm module 3 comprises a sound alarm unit and a flash alarm unit, wherein the sound alarm unit is used for sending out voice prompt for forbidding driving in; the flash alarm unit consists of red lamps and green lamps which are arranged in an array on a display screen and is used for sending out flash prompts. When the alarm module 3 is in a standby state, a green lamp of the flashing alarm unit is in a flashing state, after the alarm module 3 receives an instruction signal, the flashing alarm unit is switched from the flashing of the green lamp to the flashing of a red lamp, and meanwhile, the sound alarm unit sends out a voice prompt for forbidding driving according to the instruction signal.

And the power supply module 4 is respectively connected with the trigger module 1, the signal receiving module 2 and the alarm module 3 and is used for supplying power to the trigger module 1, the signal receiving module 2 and the alarm module 3. When the trigger module 1 is an automatic wireless remote control transmitter, a power supply is led out from the locomotive to supply power for the automatic wireless remote control transmitter; when the trigger module 1 is a manual wireless remote control transmitter, a lithium battery is adopted to supply power to the manual wireless remote control transmitter; when the trigger module 1 is a sound control receiver, the circuit in the double-track parking lot is directly connected for power supply. The signal receiving module 2 and the alarm module 3 are connected with an AC127V alternating current power supply for supplying power.
