The magnetic strength induction signal is considered as in vain).
It, can be according to the tool of cophase supply system in the Vehicular automatic neutral-section passing system under above-mentioned cophase supply mode
The method of operation that body situation predefines each phase separation point of each traction substation (pays attention to that this need to be met when determining the method for operation
The correlated condition of the method for operation), and according to the identified method of operation by control signal control the first of each phase separation point every
The on off operating mode for closing GK1 and the second disconnecting switch GK2, i.e. open and close are left, so that phase separation point is in corresponding operation shape
State.
For example, as shown in Fig. 2, when the GK1 of phase separation point and GK2 be closed (i.e. in closure position), then at the phase separation point
In through operating status；As shown in figure 3, when phase separation point GK1 and GK2 in have one closure and another disconnection (is in

When the magnetic strength induction signal of two magnetic inductors 42, then illustrate that the phase separation point is currently at through operating status or partition running shape
State.Therefore, the train will pass through (not dropping bow to pass through) current phase separation point with the method for operation not powered off, and can be by third
Signal to the 6th magnetic inductor is considered as failure.
When signal receiver 31 only detects the magnetic strength induction signal of the first magnetic inductor 41, or only detect the second magnetic
The magnetic strength induction signal of inductor 42 (only detects some magnetic induction in the first magnetic inductor 41 and the second magnetic inductor 42
The magnetic strength induction signal of device, but the magnetic strength induction signal of another magnetic inductor is not detected by the signal receiver of train 31) when,

In vehicle-mounted automatic controller 32 column will be driven according to the magnetic strength induction signal of third magnetic inductor 43 (" predicting " signal)
The main circuit breaker separating brake of vehicle.
When train passes through four magnetic inductors 44 with the method for operation of electric split-phase, if main circuit breaker separating brake not yet,
Vehicle-mounted automatic controller 32 will force the master of train according to the magnetic strength induction signal of the 4th magnetic inductor 44 (" forcing disconnected " signal)
Breaker open operation.Certainly, if the magnetic strength induction signal is considered as nothing to the main circuit breaker of the train by separating brake, the train
Effect.
When train passes through five magnetic inductors 45 with the method for operation of electric split-phase, vehicle-mounted automatic controller 32 will be according to the
The main circuit breaker of magnetic strength induction signal (i.e. " recovery 1 " signal) driving train of five magnetic inductors 45 closes a floodgate, and is restored to excessive phase front
Operating condition.
When train passes through six magnetic inductors 46 with the method for operation of electric split-phase, if main circuit breaker did not recovered to still
Operating condition before split-phase, then vehicle-mounted automatic controller 32 (" will restore 2 " to believe according to the magnetic strength induction signal of the 6th magnetic inductor 46
Number) main circuit breaker of train is forced to be restored to the operating condition of excessive phase front.Certainly, if the main circuit breaker of train has been restored to
The operating condition of excessive phase front, then the magnetic strength induction signal is considered as in vain by train.
Therefore, by the Vehicular automatic neutral-section passing system under above-mentioned cophase supply mode, that is, it may make cophase supply system
Train in system normally can operate without power-off by perforation mode or segmented mode at the phase separation point of traction substation

The magnetic strength induction signal (i.e. " recovery 1 " signal) for the 5th magnetic inductor that movement controller is received according to signal receiver drives
The main circuit breaker for moving the train closes a floodgate, and is restored to the operating condition of excessive phase front.
Step 75, when the train passes through six magnetic inductor with the method for operation of electric split-phase, if the column
The main circuit breaker of vehicle does not recover to the operating condition of excessive phase front still, then the vehicle-mounted automatic controller is received according to signal receiver
To the magnetic strength induction signal (i.e. " restore 2 " signal) of the 6th magnetic inductor force the main circuit breaker of described train to be restored to
Operating condition before split-phase.
Certainly, if the main circuit breaker of the train is by having been restored to excessive phase front when six magnetic inductor
Operating condition, then the magnetic strength induction signal of the 6th magnetic inductor is considered as failure by the vehicle-mounted automatic controller.
