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.
These four push-botton operations all adopt two key operation modes, promptly cut little ice by button, must be in conjunction with station track stopping device button sign ability executive command.[braking] expression prepares to carry out brake command to certain station track stopping device; [alleviation] expression prepares to carry out the alleviation order to certain station track stopping device; [recovering automatically] expression is carried out to go to disappear to certain station track stopping device of carrying out manually intervention and is manually intervened, and transfers automatic guidance to; [mandatum cassatorium] expression is gone disorientation station track stopping device to prepare the braking of carrying out or is alleviated order.
For guaranteeing the commonality and the railway equipment Operation and Maintenance operating specification of system, the electric flow process of each action control between system all adopts direct current 24V, the inner direct current 5V that adopts of microcomputer.The action power that is stopping device carries out the machinery and the electrical isolation of forceful electric power and light current by relay, thereby makes indoor control and action separately according to the certain direct current 24V relay of current characteristics configuration.The input and output of relay 24V direct current are by the direct control of access microcomputer of cable connection collecting part, and excessive for reducing consumption of power, microcomputer in-to-in logic determines is electrically connected and all adopts direct current 5V.
Related control information is shared mutually because system of the present invention can directly be undertaken by network connection and head process control system [TW type hump configuration type autonomous cruise speed system, FTK type hump distributed automatic control system, DDCIII type hump dual-computer redundancy autonomous cruise speed system, the integrated autonomous cruise speed system of TYWK type humping signal computing machine etc.].In the be unrealized hump field of process control of hump head, native system also possesses by directly carrying out relay system to be gathered the method for head station track information and obtains needed control information.The particular content of relevant above-mentioned head process control system here is not described in detail.
