Description
Affiliated technical field:
The utility model relates to a kind of railroad train security alarm device, particularly train safe braking warning device.
Background technology:
At present, railroad train does not have special brake safe warning device, and train is an example with the goods train before startup, train line pressure need be risen to 500Kpa by 360Kpa, and this process is called alleviation.The time length of alleviating is directly proportional with the vehicle number of train locomotive traction.Train is in startup and in service, must assurance respectively saving the airduct angle cock whole unimpeded, that respectively save the compartment of train line all opens, could guarantee safe driving and brake safe, in practical work, owing to machinery, artificial reason, may cause the airduct valve of some vehicles not open, perhaps train line breaks down, the train resting period is long, auxiliary reservoir does not have pressure yet, and connection personnel do not connect angle cock again, participates in operation under the situation that the driver does not have again to find, cause the not braking of part vehicle, bring potential safety hazard to driving.For addressing this problem, people have attempted the method for multiple safety detection, all do not obtain satisfied effect, press for a kind of safety alarm device that can in time reflect the train braking situation, guarantee the safe operation of train.
The utility model content:
The utility model purpose provides a kind of train safe braking warning device, in time detects the unobstructed state 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 electromagnetic valve, pressure sensor, A/D converter, computing machine, annunciator, telltale, solid-state relay, electromagnetic valve is arranged between train blast main and the train line, on train line, be provided with pressure sensor, the output of pressure sensor is connected with A/D converter, the output of A/D converter is connected with computing machine, the output of computing machine is connected with annunciator, telltale, solid-state relay respectively, and solid-state relay is connected with electromagnetic valve.
Also have pressure regulating valve during the utility model is formed, an end of pressure regulating valve is connected with the train blast main by pipeline, and the other end is connected with electromagnetic valve.
For preventing that accidental damage from appearring in electromagnetic valve, cause train accident, the manually-operated gate that between electromagnetic valve and train line, is provided with.When accidental damage appearred in electromagnetic valve, the manual-lock valve prevented to cause the accident to former brake system.Said computing machine can be a micro controller system.
Adopt the utility model, pressure sensor is gathered the pressure signal in the train line, enter, A/D converter is that digital signal is sent into Computer Processing with analog signal conversion, that if train line pressure occurs is unusual (can by be pre-stored in data in the computing machine compare to handle obtain a result), 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 also by the mode of operation of solid-state relay control electromagnetic valve, carries out pressurising to train line, and whether all airducts of constantly monitoring train are unimpeded fully.
Can be by mode to the train line pressurising, whether all airducts of constantly monitoring train are unimpeded fully; Also can be by train line being put the mode of pressure, whether all airducts of constantly monitoring train are unimpeded fully.
The utlity model has rational in infrastructure, in time detect the unobstructed state of train line, guarantee safe train operation, prevent characteristics such as contingency generation.Do not increase trouble, find in time whether train line unimpeded fully to train crews, 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, pressure regulating valve 2, electromagnetic valve 3, pressure sensor 4, A/D converter 5, computing machine 6, annunciator 7, telltale 8, solid-state relay 9, train line 10, manually-operated gate 11.
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 pressure regulating valve 2, electromagnetic valve 3, pressure sensor 4, A/D converter 5, computing machine 6, annunciator 7, telltale 8, solid-state relay 9, manually-operated gate 11, one end of pressure regulating valve 2 is connected with train blast main 1 by pipeline, the other end is connected with electromagnetic valve 3, the other end of electromagnetic valve 3 is connected with train line 10 by manually-operated gate 11, on train line 10, be provided with pressure sensor 4, the output of pressure sensor is connected with A/D converter 5, the output of A/D converter 5 is connected with computing machine 6, the output of computing machine respectively with annunciator 7, telltale 8, solid-state relay 9 connects, and solid-state relay 9 is connected with electromagnetic valve.
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 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, and launch train bad train of post-tensioning and train resting period are long, opens the valve portion separating vehicles and participate in operation in the absence that is not having braking.
After train is alleviated, train line pressure rises to 500Kpa, computing machine sends instruction, solid-state relay is connected electromagnetic valve, (scope of compromise is less than 520Kpa through pressure regulating valve for pressurized air, passenger vehicle is less than 620Kpa), electromagnetic valve flows to train line, train line pressure rises to pressure regulating valve pressure (for example 510Kpa--515Kpa) by 500Kpa.The vehicle number of this pressure rising time and train is directly proportional, compare with the remission time of former computing machine record, after can finding at short notice that train is alleviated, whether train line is unimpeded fully, perhaps by the people for closing or the like, and on telltale, show, if note abnormalities, annunciator sends alerting signal, reminds the staff to take measures.Train line also is directly proportional with the towing vehicle number to the time of releasing the pressure by the pressure regulating valve pressure decay, in like manner also can calculate the vehicle number of train.Can be regularly, automatic, high-frequency train line is detected, in time find the potential safety hazard of drag aspect.
In this enforcement by to train line pressurising calculate detection, can also put the pressure time by detecting train line, calculate the vehicle number of train, determine whether train line all unimpeded.
By above-mentioned several method, can find whether train line unimpeded fully in very short time, perhaps by the people for closing or the like, and on telltale, show, if note abnormalities, annunciator sends alerting signal, the prompting staff takes measures.
