Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1, a gate monitoring system based on a railway crossing comprises an infrared detector, a sound detection controller, a sound collection end relay, an infrared detector collection end relay and an audible and visual alarm, wherein the infrared detector is electrically connected with the infrared detector collection end relay and used for detecting whether a gate is closed in place or not, and the sound detection controller is electrically connected with the sound collection end relay and used for collecting train whistle signals.

When a running train enters a crossing forecast approach area (a crossing control room corresponds to the distance between the ascending of the train and the descending of the train by 2-3 kilometers), a railway electric service system forecasts that the train approaches through a crossing room alarm horn, prompts a crossing staff to close a gate in time, prohibits vehicles and pedestrians from passing through the crossing, and generates a vibration state generated when the train is broadcasted through the collected electric service alarm horn, so that a system starting trigger signal is generated, a sound collecting end relay controlled by a sound signal is closed to form a passage, an infrared detector collecting end relay controlled by an infrared detector is accessed, an audible and visual alarm is connected to the infrared detector collecting end relay, so that a power supply (not shown in the figure), the sound collecting end relay and the relay controlled by the infrared detector form a current passage, the audible and visual alarm is started by the electric alarm, when the infrared detector detects that the gate is closed in place, a break signal is sent, the infrared detector collecting end relay is switched from a normally closed state to a broken state, so that a local break is formed, the power supply alarm stops alarming, a train approach the gate is closed in place, a safety passage of the railway electric power supply is formed in the crossing, and the railway electric vehicle is prevented from being closed, and the railway electric vehicle is not closed in the crossing.

Because the sound that the electric alarm loudspeaker reported is a nonstationary continuous signal, there is the breakpoint, again because crossing traffic vehicle is of a great variety, the phenomenon of whistling is frequent, the sound magnitude of whistling, the time duration of whistling is all different, that is to say, the car is generally short, and when the train is close to the railway crossing, the time duration of whistling is longer, in order to filter these interference signals, gate monitoring system includes intelligent judgement controller again, the signal output part of sound detection controller links to each other with intelligent judgement controller, the signal output part of intelligent judgement controller is connected with sound collection end relay electricity, through screening the sound magnitude of whistling, the time duration of whistling removes these interference sources, guarantee to gather accurate train approach signal. The model of the intelligent judgment controller is YYS-2S, or other intelligent judgment controllers with the function of triggering the power-off cycle timing circuit by the pulse of the delay relay module.

Because the train running speed at the crossing is different and the surrounding environment at the crossing is different, in order to ensure the alarm accuracy of the system, a self-protection relay is added to a sound collection end relay (namely a relay controlled by a sound signal), the self-protection relay is connected to a point position alarm horn power supply line, an output point of the self-protection relay is connected to a point position controlled by the sound collection end relay, after an effective alarm signal is triggered, a circuit of the self-protection relay forms a passage to supply power to the sound collection end relay, a control coil supplies power, and after an infrared detector detects that a crossing gate is closed in place, a power supply current passage is disconnected, so that the system stops working.

As shown in fig. 1, the signal output end of the sound detection controller is connected to the input end of the intelligent judgment controller, the signal output end of the intelligent judgment controller is connected to the coil input end 14 of the sound collection end relay, the coil input end 14 of the sound collection end relay is connected to one normally closed end 4 of the latching relay, the coil input end 14 of the latching relay is connected to one normally closed end 1 of the infrared detector collection end relay, and the signal output end of the infrared detector is connected to the input end 14 of the coil of the infrared detector collection end relay; a common end 12 and a common end 9 of the sound collection end controller are connected with a power supply, a normally open end 8 of the sound collection end controller is respectively connected with a common end 12 of the self-protection relay and a common end 12 of the infrared detector collection end relay, and one normally open end 5 of the sound collection end controller is connected with the common end 9 of the infrared detector collection end relay; the normally closed end 4 of the infrared detector acquisition end relay is connected with the input end of the audible and visual alarm, the output end of the audible and visual alarm is connected with the power supply, the coil output end 13 of the sound acquisition end relay is connected with the power supply, the sound acquisition end relay is connected with a normally closed end of the self-protection relay, and the public end of the self-protection relay is connected with a normally opened end of the sound acquisition end relay.
