The utility model content:
The utility model purpose provides a kind of train safe braking warning device, detects the unobstructed state of train line in time, exactly, keeps the stable of train line, guarantees safe train operation, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: train safe braking warning device is formed and is comprised the train blast main, electromagnetic valve, pressure sensor, computing machine, annunciator, telltale, relay, train line, relay valve, overcharge reservoir, electromagnetic valve one end is connected on the train blast main, the other end is connected the train relay valve and overcharges overcharging on the airduct between the reservoir, on train line, be provided with pressure sensor, the output of pressure sensor is connected with computing machine, the output of computing machine respectively with annunciator, telltale, relay connects, relay is connected with electromagnetic valve, and relay valve is communicated with train blast main and train line.
Be provided with gauging table on relay valve blast main road, the output of gauging table is connected with computing machine.
On the brake-applying handle position of train, be provided with Hall element, be separately positioned on brake-applying handle the running position and overcharge on the position, Hall element is connected with computing machine respectively.
Said computing machine can be the micro controller system that has the A/D conversion, also can be common computer.
Adopt the utility model, pressure sensor is gathered the pressure signal in the train line, enter Computer Processing, (can compare to handle by the data when being pre-stored in that train is alleviated in the computing machine and obtain a result) if unusual, show that train line is not unimpeded fully, have accident potential, computing machine is reported to the police automatically by annunciator, telltale and is shown, remind the staff to handle, prevent accident; Simultaneously, computing machine is also controlled the mode of operation of the electromagnetic valve that boosts by booster relay, train line is carried out pressurising, and whether all airducts of constantly monitoring train are unimpeded fully.
The utility model is by the mode to the train line pressurising, and whether all airducts of constantly monitoring train are unimpeded fully.
The utlity model has rational in infrastructure, promptly and accurately detect train line unobstructed state, guarantee safe train operation, prevent characteristics such as contingency generation.Owing to cancelled pressure release valve, more safe and reliable, do not increase trouble to train crews, find in time whether train line unimpeded fully, perhaps by the people for closing or the like.
Description of drawings:
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: train blast main 1, electromagnetic valve 3, pressure sensor 4, gauging table 5, computing machine 6, annunciator 7, telltale 8, relay 9, train line 10, relay valve 11, overcharge reservoir 12, Hall element 13 and 14.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, train safe braking warning device is formed and is comprised train blast main 1, electromagnetic valve 3, pressure sensor 4, gauging table 5, computing machine 6, annunciator 7, telltale 8, relay 9, train line 10, relay valve 11, overcharge reservoir 12, Hall element 13 and 14, electromagnetic valve 3 one ends are connected on the train blast main 1, the other end is connected train relay valve 11 and overcharges overcharging on the airduct between the reservoir 12, on train line 1, be provided with pressure sensor, the output of 4 pressure sensors is connected with computing machine 6, the output of computing machine respectively with annunciator 7, telltale 8, relay 9 connects, relay 9 is connected with electromagnetic valve 3, and relay valve 11 is communicated with train blast main 1 and train line 10.Be provided with gauging table 5 on train relay valve 11 blast main roads, the output of gauging table 5 is connected with computing machine 6.Be provided with Hall element 13 and 14 on the brake-applying handle position of train, Hall element 13 is arranged on the running position of brake-applying handle, and Hall element 14 is arranged on overcharging on the position of brake-applying handle, and Hall element is connected with computing machine 6 respectively.
Working process of the present utility model is as follows: this embodiment is example with the passenger train.
Train line pressure rises to 500Kpa by 360Kpa, and this process is called alleviation.At first, computing machine detects the position of brake-applying handle automatically, has only brake-applying handle in the running position or when overcharging the position, and the utility model just carries out work, if not in running or when overcharging the position, and the SELF CL electromagnetic valve; Computing machine calculates the tractor truck number of locomotive according to the time length of alleviating, and shows with telltale then, plays two effects like this, and the one, the car number that locomotive drew under the computer recording; The 2nd, the driver compares according to number and the tractor truck number that telltale shows, judges whether train line all opens valve, prevents that the train resting period is long, opens the valve portion separating vehicles and participate in operation in the absence that is not having braking.
After train was alleviated, train line pressure rose to 500Kpa, and computing machine sends instruction, and relay is connected electromagnetic valve, and the train blast main overcharges plunger and moves to right by overcharging airduct, and train line pressure rises to authorized pressure by 500Kpa.The vehicle number of this pressure rising time and train is directly proportional, because gauging table can calculate the air leak rate of air curtain of train line, how much can more accurately calculate vehicle, when alleviating the vehicle number of record relatively, can find at short notice that train is alleviated after, train line by the people for situation such as closing, and on telltale, show, if note abnormalities, annunciator sends alerting signal, reminds the staff to take measures; When COMPUTER DETECTION rises to 520Kpa to train line pressure, relay resets, solenoid valve shuts blast main and the path that overcharges airduct, the pressure that overcharges reservoir is slowly emitted by the 0.5 millimeter aperture of diameter that overcharges on the reservoir, and train line returns to 500Kpa pressure.
