Background
In the existing signaling system, all train modes are switched by the operation of the driver. The driver can only switch modes by means of a mode selection switch or button. An advanced safeguard mode, such as an ATP safeguard mode based on vehicle-to-ground continuous communication, is provided by the system; and when the trackside equipment is in failure, a point type ATP protection mode of vehicle-ground point type communication is realized through the signal machine, and part of necessary protection is provided by the system. And in a lower protection mode, for example, when the CBTC fails, the manual protection mode (RMF) for limiting the lower interlocking level is backed up, and the system only provides protection against overspeed, and a driver is mainly responsible for safe driving, so that the mode needs to be confirmed manually by the driver.
For the time of going from the low level guard mode to the high level guard mode, the guard becomes mainly performed by the system. And considering that in the running of the train, the operation is guaranteed by adopting a high-protection mode under most conditions, if the protection mode mainly based on manual work can be automatically upgraded into the protection mode mainly based on system, the efficiency can be improved, and the risk of manual judgment is reduced.

Detailed Description
The invention will be further explained with reference to the drawings.
Referring to fig. 1, the method for converting a train mode of the present invention includes the following steps:
step one, except the mode train line of the original feedback mode input, an output interface, a selection switch and a degradation switch are additionally arranged. The method comprises the following steps:
and when the train mode is the ATP protection mode or the point type ATP protection mode, the signal system automatically outputs an ATP protection signal to the train through the output interface to drive the train line in the corresponding mode to be electrified. Namely: when the system can be automatically upgraded, the signal system needs to output a signal to the train to maintain the advanced protection mode, and the signal is equivalent to the gear position of the mode selection switch which replaces manual work by the system. When the system enters the advanced mode, the signal is automatically output to drive the mode train line of the train to be electrified and fed back to the signal system.
A degradation switch for switching from the ATP protection mode or the point ATP protection mode to the limit manual protection mode is added. The downgrade switch manually selects an input to be downgraded to a low protection mode for switching off an output of the high protection mode, thereby enabling the signaling system to enter the low protection mode. The downgrade switch is a self-resetting button because it needs to be automatically reset after downgrading because it still needs to be automatically upgraded when the conditions are met. The signal system can set a condition for entering the manual protection limiting mode and a condition for upgrading from the manual protection limiting mode, when the condition for entering the manual protection limiting mode is met, the signal system is converted into the manual forward limiting mode through the downgrading switch, and after the condition for upgrading from the manual protection limiting mode is met, the signal system can be automatically converted into the point type ATP/ATP protection mode. The condition for upgrading from the manual protection limiting mode to the point type ATP protection mode is mainly that the train establishes a position and scans a beacon which allows the signal machine to be associated, and the condition for upgrading from the manual protection limiting mode to the ATP protection mode is mainly that the train establishes the position and obtains the trackside movement authorization.
A selection switch for selecting the highest operation mode as an ATP protection mode or a point ATP protection mode is added. And the protection mode type is used for limiting whether the low-level protection mode can enter ATP or point ATP.
The input of the mode train line in the train circuit is judged according to the following conditions, and the modes of the most basic three levels in the subway train control system are listed.
Obtaining electricity of the train line in a point type ATP/ATP protection mode, namely BAT + ATP (signal output);
wherein BAT represents train power supply, ATP represents system output excitation ATP protective signal relay,
the system does not output an excitation ATP protection signal relay.
For train mode, the mode train line feeds back the final mode. The limited human defense mode is first entered from the standby mode, which would require manual operation. For the limited manual safeguard mode, the mode is established under the condition that the system does not output the ATP safeguard signal and obtains power from the limited manual mode train line obtained from the vehicle, wherein only the forward limited manual safeguard mode can be continuously and automatically upgraded to the ATP or point type ATP safeguard mode because the directions of the two modes are forward. For the ATP protection mode, the condition that the mode is established requires that the highest mode input received by the system is the ATP protection mode, in addition to the power on of the train line in the ATP mode corresponding to the feedback of the vehicle after the system outputs the ATP protection signal. For the point type ATP protection mode, the condition for the mode establishment requires that the highest mode input received by the system is the point type ATP protection mode, in addition to the power on of the train line in the ATP mode corresponding to the vehicle feedback after the system outputs the ATP protection signal.
Step two, performing mode conversion, as shown in fig. 2, including:
when the train mode is the manual protection limiting mode, the highest operation mode is the point type ATP protection mode, and the condition that the preset manual protection limiting mode is upgraded upwards is met, the signal system automatically converts to the point type ATP protection mode without stopping. In fig. 2, IM denotes a selector switch.
When the train mode is the manual protection limiting mode and the highest operation mode is the ATP protection mode, and after the condition that the preset manual protection limiting mode is upgraded upwards is met, the signal system is automatically switched to the ATP protection mode without stopping.
When the train mode is a point type ATP protection mode and the highest operation mode is switched to the ATP protection mode, when the train-ground communication is recovered, the signal system automatically switches to the ATP protection mode without stopping. If the highest operation mode level is the point type ATP protection mode, the train can be maintained in the point type ATP protection mode and will not be automatically upgraded.
When the train mode is the ATP protection mode or the point ATP protection mode, the input of the degradation to the manual protection limiting mode is provided for the signal system by pressing the degradation switch, the train stops, and the signal system is switched to the manual protection limiting mode. In fig. 2, RM denotes a degradation switch.
When the train mode is the ATP protection mode and the highest operation mode is switched to the point ATP protection mode, the signal system applies emergency braking to the train, the train can be degraded to the manual protection limiting mode through the degradation switch after being stopped, and the train is automatically upgraded to the point ATP protection mode.
Meanwhile, after the preset condition of entering the manual protection limiting mode is met, the degradation switch is lightened. Namely: the manual operation of the driver is prompted by the output button lighting signal. For example, when it is determined that the train is at a preset distance from the train section or the parking lot, the degradation switch is turned on to prompt the driver to operate, and once the driver operates, the degradation switch is turned off.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
