Abstract

The utility model relates to an anti-collision and early warning device of a railway train. A magnetic sensor is arranged on the railway, and is connected with a signal process device by conductors, and a support fixing magnet block is arranged on the axle of the train. When the train passes the railway, the magnet block on a support is corresponding to the magnetic block position of the sensor, and the magnetic contact of the sensor opens the circuit under the magnetic function. The resistance value of the sensor line can be smaller, and the changed signal displays the driving position of train on the display screen when passing through signal process device. When the railway is broken because due to natural disaster or manual destroy, the resistance value stays at a certain value after changing, and when the value exceeds the set time limit, the occurrence of abnormal situation of the railway can be known, so the managers immediately adopts the emergency plan to process the abnormal situation according to the situation, so that the train accident of counterclockwise driving caused by broken rail or staggered track is avoided.

Description

The railroad train anti-collision prewarning apparatus

Affiliated technical field

The utility model relates to a kind of railroad train safe operation scheme, specifically a kind of railway rail that breaks, the wrong road of train and move caused overturning, collision grave accident prior-warning device in opposite directions.

Background technology

Now, because of the disconnected rail of railway, the grave accident of train wrong road overturning that operation causes, collision happens occasionally, be that country advanced and that fall behind all has this type of accident case, China recent years also has generation, more piece railway carriage side is anti-after Jinan, Shandong two trains collide recently, causes the dead and injured Extra Serious Accident of people more than 400 of people more than 70.But this prior-warning device on the way is rarely found on railway at present, and costs an arm and a leg.

The utility model content

In order to overcome the disconnected rail of railway, the wrong road of train and the overturning that causes of operation in opposite directions, the problem of collision.The utility model provides a kind of railroad train anti-collision prewarning apparatus, can not only the early warning railway disconnected rail of this device, and the wrong road problem that can early warning two trains goes in the same direction on track at bar.

The utility model solves the technical measures that its technical matters takes; In the inboard of two rails every a segment distance sensor installation, each sensor connects with two parallel leads, one end terminal point of lead connects signal processor unit (prior art), signal processor unit one tunnel is transported to read-out, two the tunnel transport to disconnected rail acoustic-optic alarm, and three the tunnel transport to the train warning device that travels in opposite directions.Article two, the uplink signal when one of the sensor signal of rail is train operation, another side are the downlink signals, when uplink and downlink send signal simultaneously, are defined as two row and operate on same the rail, and be to go in the same direction.If rail runs into disaster (as landslide, landslide etc.) or artificial destruction, be directed at disconnected rail, then sensor will send disconnected rail signal, and can clearly show the correct place of disconnected rail.The source of above-mentioned signal all obtains by sensor.Sensor is made up of fixed contact, moving contact, magnetic block, resistance, the shell bottom surface of sensor is fixed on a side of rail, install and fix the contact in the housing, centre in fixed contact, place the magnetic block of T word shape, connect moving contact on the magnetic block, fixed contact, moving contact be connecting wire respectively.Magnetic block in the state lower house is adsorbed on the shell base plate, and moving contact contacts with fixed contact and forms path.Fixed support on the wheel shaft of train, a magnetic patch is fixed in the lower end of support, this magnetic patch is the interior magnetic block of respective sensor just in time, these two magnetic substance polarity are opposite, the powerful magnetic strength of in housing, adsorbing on the shell base plate of magnetic on the support, magnetic block when therefore meeting in the housing is adsorbed and leaves the shell base plate, driving moving contact and fixed contact simultaneously throws off, formation is opened circuit, two parallel leads are connected on fixedly touching to go up with resistance surely and be connected in parallel in the housing of sensor, and the formation resistance loop is according to Ohm's law and Ke Xihe law, when resistance was in parallel, its equivalent resistance was

\frac{1}{R} = \frac{1}{r_{1}} + \frac{1}{r_{2}} + \frac{1}{r_{3}} + \cdot \cdot \cdot \cdot \cdot \cdot + \frac{1}{r_{n}}

That is:

\frac{1}{R} = Σ \frac{1}{r}

As seen resistance its equivalent resistance in parallel is less than any shunt resistance.Resistance value when therefore the resistance loop of being made up of the resistance on the several sensors and lead has calculated sensor that each resistance forms in the circuit present position according to above-mentioned formula when designing, if any section lead in the clear the circuit, this loop will diminish, and its resistance value promptly can increase.

Therefore, when train through out-of-date, magnetic block on the wheel shaft attracts the magnetic action in the sensor, makes its contact throw off line broken circuit, resistance loop just diminishes, its resistance value will change, and this resistance signal that has changed reaches signal processor unit (prior art) by lead, and signal processor unit calculates sensor position on rail of carrying this resistance according to the size of resistance value, indicate by read-out, train moves on which section road.If the existing train of uplink is travelling, downlink has the signal of train driving again, these two signals are just overlapping in signal processor unit so, and signal processor unit will be exported the emergency alarm of acousto-optic immediately, and prompting vehicle scheduling personnel have train to travel in opposite directions on a rail simultaneously.On read-out, also can find out simultaneously, the travel direction of two trains and distance, the dispatcher just can enter emergency preplan immediately and handle.

If disaster or artificial destruction are directed at the disconnected rail of railway, the connecting wire that is fixed on the rail upper sensor also can rupture, and this resistance loop of broken string back diminishes, and resistance value will rest on a certain value and immobilize.If this resistance value surpasses the design-calculated time and do not change, the signal of railway at the disconnected rail of that fragment position will take place in signal processor unit immediately so, and the person of inspecting the road can rush to the scene immediately and handle, or enters emergency preplan and handle.Thereby reach the purpose of railroad train anti-collision early warning.

The beneficial effects of the utility model are; Provide a kind of train crash-proof prior-warning device to railway interests, avoid train because of disconnected rail, Cuo Dao the travel overturning that causes, the grave accident that collides.Simple in structure, cheap.
