Description
Technical field
The present invention relates to the marshalling yard that railway is provided with hump stopping device is carried out the automatically controlled system, relate to more specifically the anti-slide equipment of controlled stopping device, by gathering hump head and trim end job information autonomous cruise speed system and method the anti-slide equipment of stopping device as the basis.
Background technology
At present, along with hump head the improving constantly of degree of automation of shunting, head disintegration ability has had raising by a relatively large margin, and operating personnel's working environment has also had change by a relatively large margin.But the hump operation is as a disintegration, assembly, the Trinitarian overall operation process of marshalling, mutual restriction between the three, and any one process is restricted, and all can directly influence the further raising that hump is separated the volume ability.But owing to the ignorance to the afterbody make up capacity, cause end to end the overbalance of separating, compile ability for a long time, the raising of afterbody make up capacity and safety become the further limiting factor of raising of the whole gravitation marshalling yard integration capability of restriction.
For a long time, trim end anti-sneak away during work hours tool mainly with skate as main marshalling facilities, skate is fit to China's national situation and road feelings at that time as a kind of easy speed governing and anti-slide equipment really in the hump early stage of development.Use skate to prevent the slide operation at trim end, in operation process, by artificial contact, actual observation switching locomotive operation situation, the artificial assurance carried out ' putting footwear ' and ' removing footwear ' operation process, and not only labour intensity is big, and operating environment is abominable, and efficiency is low, directly has influence on the further raising of trim end make up capacity.Even more serious is that the accident in shunting operation that causes because of ' leakage is put ' and ' leakage is removed ' skate happens occasionally at trim end.
Along with the continuous development of technology and further developing of the division of labor in society, use skate to carry out the main activity in production of shunting if still adopt high-intensity manual labor, the technical development policy that not too meets China railways, and also incompatible with the development need of social progress.
In recent years, effort through vast railway scientific and technical personnel, vehicle anti-skid problem at bowl end, the parking apparatus of succeeding in developing mainly contains stop top and stopping device, stop and push up the kinetic energy that the deceleration top of adopting continous way cloth zero setting critical speed disperses to consume the traveling vehicle, effectively the length influence is bigger to exchange fare.Stopping device adopts point type to arrange to concentrate the kinetic energy that consumes the traveling vehicle, its development to experience non-control state progressively to be tending towards maturation to the development of may command state.
Stopping device is as an independently vehicle anti-skid equipment use, do not set up certain operation contact as operation end to end, only rely on range estimation line travelled by vehicle state and the afterbody situation of shunting of shunting, adopt the operating condition that manual terrain is handled or manually centralized control carries out stopping device to change.Because the particularity of hump operation and the restriction that is subjected to the condition of watching from a height or a distance, not but still can cause labor intensity of operating staff to increase the weight of, does not shift in the place that forms labour intensity, and very easily cause stopping device ' to leak system ' and ' leak and delay ', thereby influence Shunting Service Efficiency, form certain job safety hidden danger.

According to following formula, collude speed and energy after the car collision before and after can obtaining, thereby obtain separately a number that skids off by the stopping device glancing impact.The rest may be inferred, just can obtain the vehicle number that finally skids off stopping device in the continuous throwing operation process.
Determining of stopping device rational position depends on construction features and the technical index (effectively braking length, unit system kinetic force) and the residing on-the-spot profile condition of stopping device itself.Simultaneously, also closely related with the operation property of the line of shunting (stopping device entrance velocity, wagon flow distribution, bare weight ratio, collude number, whenever collude a number).Have only by in conjunction with the field operation process, satisfying under the condition of field work safe, the artificial site operating environment just can be determined the position that is provided with of stopping device with suiting measures to local conditions.
Generally speaking, do not need manual intervention, system is by gathering braking or the alleviation and the record operation process of each station track stopping device of operating condition automatic guidance end to end.Prompt for [automated manner] on the screen this moment, is [manual mode] as screen prompt, can carry out the state of a control conversion by [conversion] and [automatically] button of pushing manual dish.
According to the operation needs, allow to carry out the control of manual intervention stopping device, and be better than automatic guidance.By utilizing keyboard or mouse to finish on graphic terminal operation screen, this screen can carry out the selection of certain operating mode according to operation habit for the multi-screen operation interface.
Be shown as on-the-spot stopping device and station and yard plan arrangement plan on the main screen, the shunt traveling situation of line skating vehicle of shunting signal, branching turnout section, shunting route and the head that comprises each station track of afterbody is represented.The System menu prompt column is arranged at top.Can necessarily be provided with according to content in the menu item and bottom order relevant explanation.The screen middle part is the prompt operation zone of operation scheme and mouse or trace ball, and automatic/hand state, braking, alleviation, removing, automatic four the square frame buttons of recovery are arranged.
The upper left corner is the menu setting hurdle, and title is represented this terminal for [operation screen] and be operator's operation screen that the upper right corner is present system time, can adjust by menucommand.The lower right corner is whether this terminal is synchronous with main frame.
Equipment should be on line state under the normal condition, shows with main frame to link, and is in line states.Off line state shows this terminal and main frame isolation, is in not presence; This order can be confirmed whether online and on-line operation of terminal and main frame when starting.
Equipment should be in principal and subordinate's on line state under the normal condition, shows that this operating terminal and main control computer are synchronous, can carry out associative operation.Although it is online that principal and subordinate's off line shows this terminal and main frame, but it is asynchronous with main frame, promptly out of touch, state of a control and on-the-spot existing condition may be inconsistent, at this moment should use the log-in order in the menucommand to confirm, if still can not recover, the devices illustrated et out of order, should turn to manual operation state, and inform that the maintainer keeps in repair.
