The common formation two cover microprocessor control systems of the main control system of two-node cluster hot backup and lower floor's workstation, described two cover microprocessor control systems include rate control module and route control module, be used for weight, push-up speed and hump plane vertical section according to skating vehicle and relevant rolling condition, calculate and the entrance velocity of control vehicle, the exit velocity of line speed and vehicle of slipping, this system controls by outdoor facility and indoor equipment and constitutes automatic guidance to sliding hook vehicle;
Marshalling yard color graphics workstation is used for the real-time demonstration of hook car rolling process; Print alarm message, the handling labor station be used for rolling process and system alarm information preservation, retrieve, search, also be used for the state-detection and the troubleshoot of system equipment;
Relay assembly equipment is in the system chambers and the bound fraction of outdoor facility, is the execution link of control mechanism, is provided with the concentrated and controlled automatically deceleration of route top execution relay, is used for the execution of speed and route control command;
Line related screen and system's uninterrupted power supply (UPS) are used for the supply regular power of control convenience and the continuous power supply that power supply switches.
2, a kind of control method of utilizing route and velocity information to control the automatic speed regulation of controlled deceleration jacking row hump comprises in a kind of control method of utilizing route and velocity information to control the automatic speed regulation of controlled deceleration jacking row hump that is made of outdoor facility and indoor equipment:
According to the controlled deceleration of high line principle arrangement pushing up;
Receive and handle that hump rolling route measuring vehicle weight, track circuit test the speed, the station track surveys long, profile information flat with hump and the relevant hook car parameter of speed control;
According to above-mentioned information and the rolling condition that provides, calculate and determine entering of each section controlled deceleration top top group's entrance velocity and slip out controlled deceleration top top group's exit velocity;
According to above-mentioned entrance and exit speed control correlation parameter, determine that amount is served as a fill-in in the controlled deceleration of may command in this slide conduct road, station track;
Determine that in conjunction with station track survey length and hook vehicle number place, comprehensive hook car weight amount are hung by the company of standing car on sliding hook vehicle and the station track and the station track is flat, the profile feature, calculate and determine that this sliding hook vehicle serves as a fill-in in the controlled deceleration that it slips the actual braking of conduct Lu Shangxu, consider the temperature effect effect simultaneously, serve as a fill-in and hook car entrance velocity according to the layout that enters current controlled deceleration top group, determine the braking quantity of this hook car on this top section, match with the hook vehicle number, by calculating final braking or the alleviation opportunity of hook car on this Duan Dingqun determined, to reach desired braking effect.
3, according to the method for claim 2, the arrangement principle on the controlled deceleration of the high line principle arrangement of described energy top is:
(1) on every grade of different track switch of rolling section of hump, according to different definite its maximum amounts of serving as a fill-in of arranging of branching turnout model;
(2) on the track circuit of the short rail of branching turnout protection section, can not arrange the top of slowing down in principle;
Judge by the speed that enters top group that calculates that (3) if easy rolling car is easily gone the condition rolling to should controlled deceleration top during section, when the controlled deceleration top of layout was the work of resistance, then this controlled deceleration was pushed up and can not established.
4, according to the method for claim 3, described calculating and definite sliding hook vehicle by the entrance velocity of each top, controlled deceleration top section, the pass of exit velocity are:
For a cloth top section, its inlet/outlet speed satisfies following formula:
In the formula:
V
Go out-vehicle goes out the calculating exit velocity (unit: m/s) of top section clearly
V
Go into-vehicle enters the entrance velocity (unit: m/s) of top section
G '-vehicle acceleration due to gravity (unit: m/s
2)
The gradient (the unit: ‰) at i-section place, top
Total drag (the unit: N/KN) of w-vehicle operating
L-top segment length (unit: m)
N-top section is arranged and is served as a fill-in (unit: platform)
Braking/the work of resistance on R-top, its value depend on that vehicle enters the entrance velocity of top section
Q-vehicle weight (unit: KN)
Wherein, according to the weight of calculating vehicle, the entrance velocity V that track circuit records
Go intoThe rolling condition of peace, profile calculate to be determined the entrance velocity of each top section, slips row exit velocity V every the certain step size computation vehicle less than cloth top spacing
Go outAnd the action accumulative total different operating state that pushes up according to slowing down is useful, until top group's outlet, just can draw vehicle through the actual exit velocity of this section top group time and top group's mode of operation, if vehicle enters the critical speed that top group's entrance velocity is lower than the top of slowing down, then this Duan Dingqun of supposition is the exit velocity of the direct release state computation vehicle of the work of resistance earlier, if it calculates still subcritical speed of exit velocity, then can determine this Duan Dingqun at vehicle through out-of-date for the direct release state, its actual exit velocity is for calculating exit velocity; Be higher than critical speed if calculate exit velocity, according to cyclic iterative method, just useful and its actual exit velocity that can draw this top section braking and alleviate.
