Description
Technical field
The invention belongs to track traffic brake hard technology, more particularly, to a kind of urgent system of rail vehicle in rescue
Dynamic synchronism control circuit and control method.
Background technology
Hong Kong south Hong Kong line is the first complete unpiloted high-end metro project that long-traveller joint-stock company makes for Hong Kong, row
Car is using 3 marshallings, and based on contract with vehicle safety requirement, brakes must use the system based on every bogie
Dynamic control form（Hereinafter referred to as frame control）, i.e., each bogie is equipped with 1 set of brak control unit, totally 6 sets of full train, and then ensures
The minimum influenceed in the case of brak control unit failure on car operation.Due to being the vehicle configuration of full motor-car, believe in addition
Number a variety of antennas of system configuration and the reasons such as Derail detector are equipped with, cause to be laid out epitonos under vehicle car, while base
In the demand of vehicle loss of weight, therefore it just have selected at the beginning of the project implementation and control autocontrol system using frame.
For ensure to require in the safety of personnel and vehicle, client's contract during rescuing disabled vehicle and relief car not only through
Hitch is connected and it is necessary to ensure the synchronism braked during rescue, i.e., brake and alleviate simultaneously, and disabled vehicle needs to consider electric power storage
Pond shorted to earth etc. limiting condition.Brakes supplier responds this and requires and successively use train pipe, increase two-way valve etc.
Etc. scheme, but because scheme itself existing defects are finally denied, each car is helplessly recommended to be equipped with 2 sets of tradition based on every
Brak control unit based on car（Hereinafter referred to as car control）Car control system realize frame control.Although this design is in work(
Can and performance on disclosure satisfy that installation space under requirements, but vehicle car, cost control, vehicle weight such as limits at the beam of factor
Tie up, can not realize at all.Therefore brake synchronous during both can guarantee that vehicular rescue is searched out, automatic driving car is can be suitably used for again
The method of feature is extremely urgent！
Synchronism control during traditional rescue is the form by train pipe, train pipe highest operating air pressure be 5bar or
6bar, is alleviated, the control mode of exhaust brake using inflation.It is required to be equipped with list for two trains using traditional rescue mode
Only train pipe and corresponding train pipe instruction issuing apparatus and train pipe instruction executing device, braking instruction passes through train pipe
Pressure change transmitted.If vehicle needs rescue, relief car carries out carrying out hitch even extension, two row after the proteges of the powerful who stay with their benefactions like parasites with disabled vehicle
Car carries out brake synchronous control using train pipe.Relief car use " loopback cell " changes into control instruction in the gas of train pipe
Buckling, and transmitted by train pipe, take and fill wind alleviation, be depressured the control mode of braking, disabled vehicle is used
" STV200 " train order reception apparatus, by train tube pressure change represent braking instruction understood and be converted into accordingly
Brake pressure is exported.
It is not difficult to find out by above content, must not for realizing the control for brake during train rescuing by train pipe
Do not face problems with：
1st, " discounting " of synchronism
Because braking instruction is realized by the pressure change in train pipe, in view of the compressibility and air of air are in pipe
The limitation of flowing velocity, the synchronism of Train Control will be carried out " discounting ", and according to test data, each car needs delay about 0.5
Second., it is necessary to be delayed 3 second time for the vehicle of 2 row, 3 marshallings.
2nd, the demand of installation space, cost control and weight
The mode of train pipe is taken, it is necessary to be equipped with single train pipe and corresponding train pipe instruction issuing apparatus and train pipe
The substantial amounts of materials and parts such as instruction executing device and control valve class, this undoubtedly gives installing space, cost control and the control of weight of vehicle
System proposes stern challenge.
The content of the invention
It is an object of the invention to provide one kind when failure train braking can not be alleviated, can Synchronization Control breakdown train and
The control circuit and control method of failure train, make train rescuing safe and reliable.
For achieving the above object, the present invention provides a kind of rail vehicle rescue brake hard synchronization control circuit, its
It is characterised by：Access in parallel hangs together the normally closed of relay on the brake hard train line loop of relief car and the head car of disabled vehicle
Contact and brake hard relay, brake hard train line loop is rebuild after even being hung for breakdown train and failure train；Meanwhile,
In the head car arrangement brake disconnecting switch of relief car and disabled vehicle, relay end to end and braking isolation relay are rescued in parallel connection access
Device, the emergency stop button normally-closed contact of driving position seals in brake hard train line loop, the braking isolation electromagnetism of all vehicles
The urgent train line loop of valve parallel connection access, by urgent train-line loop power supply, by controlling urgent train line loop, so as to control
Isolation solenoid valve is braked, is realized under rescue operating mode, brake hard synchronism control.
Described braking isolation solenoid valve is arranged at the upstream of brak control unit, positioned at hand brake isolation cock and system
Between dynamic reservoir.
A kind of rail vehicle rescues brake hard synchronisation control means, it is characterised in that comprise the following steps：
1st, braking disconnecting switch is closed in fault car, powered from breakdown lorry to fault car by standdle carrier line, failure
The rescue that vehicle and relief car are connected relay activation end to end so that braking isolation solenoid valve obtains electric, reaches emptying checking cylinder pressure
The purpose of contracting air, realizes the alleviation of braking；
2nd, when needing to apply the emergency brake on breakdown lorry again, the brake hard actuating of relay on relief car is normally opened
Contact is disconnected, the dead electricity therewith of the braking isolation solenoid valve on disabled vehicle, and compressed air is transported in checking cylinder again in gas circuit,
Disabled vehicle brake hard applies, and realizes the synchronous braking of disabled vehicle；
3rd, when needing to apply the emergency brake in disabled vehicle, now the braking disconnecting switch on disabled vehicle has got to braking isolation
Relay all the way, relief car braking loop by disabled vehicle braking disconnecting relay control, if emergency stop button by
Activation, the braking disconnecting relay of disabled vehicle is also by dead electricity, and the braking disconnecting relay normally opened contact connected into relief car is by closing
Conjunction is transformed into disconnection, and the brake hard train-line of relief car dead electricity therewith, relief car is also applied with brake hard.
The positive effect of the present invention is as follows：
1st, the requirement of brake synchronous during rescuing is fully achieved, it is to avoid using " discounting " of the synchronism of tradition machinery mode
Problem.This scheme has been completed verification experimental verification, and applies on the railcar of the southern Hong Kong in Hong Kong, and vehicle has put into commercialization
Operation.
2nd, due to the application of technique, it is that whole project saves more than 300 ten thousand yuan of buying expenses, generates good economy
Benefit.This theory for rescue during synchronism control started the beginning, and by according to the application of the demand of owner at home and abroad its
On his vehicle, and then bring good social benefit.
3rd, this design makes single vehicle loss of weight 81kg, complete 3 marshalling loss of weight 243kg of row, is at present already close to axle weight pole
The vehicle weight management of limit is made that prominent contribution.Installation space is saved simultaneously, is full motor-car+unpiloted car
Configuration ensure that installation and safeguard space.
