Description
Technical field
The utility model relates to a kind of train approach warning device, and a kind of ultrasound wave train approach warning device is provided.
Background technology
For guaranteeing the safe operation of train, rail track need to often be maintained, greatly, in repair the construction and maintenance activity be the assurance train operating safety important means, guarantee driving, construction safety and workmen's personal safety has just become a very important job, and the part railway is located in the mountain area, curve is many, radius is little, the large bad visibility of mist, in recent years again because multiple line open-minded, the continuous speed-raising of train, the Rapid Popularization application of automatic block district and popularizing of electric locomotive, the reduction of locomotive noise, train is followed the tracks of operation, the raising of rate of traffic flow and speed, the be engaged in minimizing of staffing of worker, operating personnel on the line, it is dynamic that the trackwalker is difficult in time to grasp train operation, to constructing on the line, inspect the road, patrol and guard the road junction guard, electricity affair operating personnel's personal safety and construction traffic safety have consisted of serious threat.Cause the shape driving accident, personal casualty accident happens occasionally outside the great road of driving accident, automobile and the train colliding of maintenance, workmen's human casualty accident, train track maintenance implements, according to statistics 27% of human casualty accident, 82% of driving accident all be because construction to dodge train untimely, or in time do not recover circuit and the running status of therefore grasping at any time train that causes, therefore to traffic safety, construction maintenance personal's life safety is all most important.
Life security for protection construction maintenance personal, train approach warning device has obtained application, the signal that existing train approach warning device gathers Train Approaching adopts infrared ray to realize the employing Magnetic Sensors without exception such as train speed registering instrument, intersection alarm device; Because Magnetic Sensor must be fixed on the rail and could detect, the induced signal of sampling train.Therefore, a cover magnet sensor arrangement dismounting is very loaded down with trivial details, and needs several meters long cable, thus install carry very inconvenient; While Magnetic Sensor low-speed performance is poor, electrified section is disturbed larger.And also have and adopt infrared sensor, but installation accuracy is inadequate, and the wrong report situation occurs owing to be subject to external interference in vibration transducer easily.
Summary of the invention
The ultrasound wave train approach warning device that provides a kind of reliability strong is provided the purpose of this utility model.
The utility model is to achieve these goals by the following technical solutions:
A kind of ultrasound wave train approach warning device is characterized in that comprising Receiver And Transmitter,
Described transmitter comprises ultrasonic sensor, signal receiving circuit, driving circuit, central processor CPU, modulation circuit, power amplifier, antenna, described ultrasonic sensor is connected with central processor CPU with driving circuit by signal receiving circuit, and described central processor CPU, modulation circuit, power amplifier, antenna are linked in sequence.
Described receiver comprises antenna, receiving demodulation circuit, decoding scheme, central processing unit, driving circuit, the loudspeaker that is linked in sequence, and described driving circuit also is connected with alarm lamp, and described central processing unit also is connected with push-button unit and liquid crystal display.
In the such scheme, described transmitter and receiver all adopts battery and the power supply of sun power electroplax.
The present invention has following beneficial effect:
The utility model adopts ultrasonic sensor to gather the signal that train arrives check point, ultrasonic sensor can detect the train that passes through beyond the 3-5 rice reliably, it has not only solved the weight that Magnetic Sensor can't overcome, has carried inconvenient problem, and has solved the unappeasable precision problem of infrared sensor.The utility model small investment, effect is remarkable, has alleviated greatly security protection personnel's labour intensity.This equipment has not only solved employment and has protected issuable dangerous factor, and can reduce or do not need protected personnel, and its Social benefit and economic benefit is remarkable.

Embodiment
The utility model provides a kind of ultrasound wave train approach warning device, it is characterized in that comprising receiver and at least 2 transmitters,
Described transmitter comprises ultrasonic sensor, signal receiving circuit, driving circuit, central processor CPU, modulation circuit, power amplifier, antenna, described ultrasonic sensor is connected with central processor CPU with driving circuit by signal receiving circuit, and described central processor CPU, modulation circuit, power amplifier, antenna are linked in sequence.
Described receiver comprises antenna, receiving demodulation circuit, decoding scheme, central processing unit, driving circuit, the loudspeaker that is linked in sequence, and described driving circuit also is connected with alarm lamp, and described central processing unit also is connected with push-button unit and liquid crystal display.
In the such scheme, described transmitter and receiver all adopts battery and the power supply of sun power electroplax.
The below is described further the utility model:
The utility model is made of two transmitters and a receiver,
The place of 1-1.5 kilometer arranges respectively a dedicated transmitter in the distance road junction up-downgoing moon, be equipped with one over against the rail outside on this transmitter and overlap ultrasonic sensor, ultrasonic sensor constantly outwards sends out ultrasound beamformer at ordinary times, when train is reflected back and is received through out-of-date ultrasonic beam, ultrasonic sensor is triggered and opens the emitting head power supply and control it to the road junction emission radio signal of sending a car like this.Ultrasonic sensor is that antijamming capability is strong, energy consumption is little, efficient is high because it has, adapts to the characteristics such as open-air open-air atmosphere ability is very good, and for example widely applying the radar for backing car at the car rear portion now is exactly ultrasonic sensor.
The road junction treating apparatus is a special receiver, in case receive the wireless signal of sending a car of transmitter just open immediately power amplifier by loudspeaker play " rub-a-dub, rub-a-dub, rub-a-dub, rub-a-dub, train is coming, please note! " warning sound.Receiver and loudspeaker etc. can be installed on room, the road junction metope, also can install near the electric pole the road junction.Warning sound is play and generally automatically to be stopped after about 1-2 minute, and about 5 minutes of automatic blocking receiver subsequently, with the received and emission false alarm of the wireless signal of sending a car that can launch again during a little while again through transmitter in the other direction after avoiding train to pass through.
