Description
Technical field
The present invention relates to rail transit train control fields.
Background technology
Rail traffic signal system by means of continuous vehicle two-way communication, communication-based train control
(Communication Based Train Control, abbreviation CBTC) system realizes the real-time control to train, effectively contracts
Train Interval is subtracted.Fig. 1 gives the Organization Chart of CBTC systems.
The CBTC project implementations and operation during, equipment component failure due to the duration or in CBTC systems and cannot
It realizes the operation of CBTC global functions, introduces back-up system in this case.There are two types of modes for back-up system：One kind is based on connection
The back-up system of lock, vehicle do not communicate between ground, and train is driven according to the display of trackside semaphore by driver.Another kind is base
In the back-up system of point type, it realizes the control to train in a manner that unidirectional information is transmitted to vehicle based on the ground of point type；
Two kinds of standby modes are all widely used in engineering.In current CBTC projects, back-up system is not individually a set of
System, and be integrated into CBTC systems, provide emergency function after CBTC system degradations.
For the ease of analysis, will CBTC trains, non-equipment train and degradation be defined as with the train of CBTC mode operations
Train for backup mode is defined as non-CBTC trains.CBTC trains are driven a vehicle by mobile authorization information and cab signal, are not required to
Want trackside semaphore.But non-CBTC trains still need trackside signal and show the state for informing route in front of driver in real time,
Driver instructor drives train operation.
In current CBTC systems, trackside semaphore is the equipment being configured for back-up system, after Signal layout is also pressed
Standby system principle designs.Main track semaphore mainly has points protection semaphore, outbound letter according to its installation position and function distinguishing
Number machine, Wayside signal, block signal machine and main track entry signal machine.For non-CBTC trains, all semaphores press standby point
Lamp principle is shown.For CBTC trains, main track entrance and block signal machine generally are normality lighting lamp state, other signals
Machine shows normality as described below and turns off the light and normality lighting two schemes：
1) it turns off the light scheme
Under CBTC patterns, semaphore is turned off the light, and train is using cab signal as train signal.Train is downgraded to non-CBTC row
Vehicle, train-approach signal machine answer lighting, and train shows according to trackside semaphore and drives a vehicle, if the train can in front of semaphore
Upgrade into CBTC trains again, semaphore will turn off the light again.During Signal lighting, when permission light is turned off the light for some reason, red signal of changing the time.
When red light cannot be lighted for some reason, disable signal is considered as non-CBTC trains.Semaphore lights the free time for checking route.
2) lighting scheme
It is also non-CBTC trains that the train for not considering close centrality, which is CBTC trains, all equal normality bright lights of semaphore.
By the operating status " CBTC trains " of train, still " non-CBTC trains " sends interlock device to CBTC trackside equipments.Interlock device root
Information accordingly, by different lighting principle clearing signal machines.If being CBTC trains close to the semaphore, the opening of semaphore is not
It checks the conditions such as section free time, corresponding semaphore is opened according to mobile authorization, is consistent with cab signal；If non-CBTC
Train, semaphore opening need to check section idle condition.After signal at clear, if the permission signal (such as green light/amber light)
Filament double break, for CBTC trains, red signal of not changing the time, semaphore, which is turned off the light, does not influence the operation of train；Non- CBTC is arranged
Vehicle allows signal that should switch to disable signal, and train must stop before the semaphore.When semaphore red light filament double break, for
CBTC trains such as allow signal filament intact, can open permission signal.For non-CBTC trains, turn off the light to be equal to and forbid letter
Number, train must stop before the semaphore.
Normality is turned off the light and lighting program analysis：From the above, CBTC systems will be different CBTC engineering projects
Offer semaphore is turned off the light or lighting scheme, but in semaphore turns off the light scheme, also to consider the main track entrance of normality bright light in fact
It is completely the same with block signal machine, the lighting principle of this two classes semaphore and under lighting scheme, that is to say, that in the scheme of turning off the light
The lighting function of semaphore has been included in fact.In addition, letter can not be usually detected since semaphore normality is turned off the light under the scheme of turning off the light
The good working condition of number machine filament, so as to influence the use of backup mode.Off-the-shelf item during stoppage in transit generally by forcing point red
Lamp inspection, which is surveyed red light filament and reduced, to be influenced, but the filament of signal is allowed still cannot to detect.
