The method for train speed limit based on RM according to the embodiment of the present invention is described in detail by fig. 1.
In order to better understand the technical solution of the present invention, the method for limiting speed of train based on RM according to embodiment of the present invention is described in detail below with reference to fig. 1, and fig. 1 is a flowchart illustrating the method for limiting speed of train based on RM according to embodiment of the present invention.
As shown in fig. 1, the method for train speed limit based on RM in the embodiment of the present invention includes the following steps:
and S101, acquiring the position information of the target train.
And S102, acquiring the train speed limit value matched with the position information according to the position information.
And S103, determining the emergency braking trigger speed value of the target train based on the train speed limit value.
In the embodiment of the invention, the train speed limit value is associated with the position information of the train, and the emergency braking trigger speed value of the target train is determined based on the train speed limit value matched with the position information, so that the running efficiency of the train can be improved, the high-voltage load of the train is prevented from being disconnected when the train passes through a phase separation zone, and the running safety of the train is further improved.
According to embodiments of the present invention, a Zone Controller (ZC) can obtain location information of a target train from a location of a head of the target train and a location of a tail of the target train, the location information may further include a traveling direction of the target train, and from the location information of the head of the train and the location information of the tail of the train, the ZC can determine whether the target train is completely within a line section or partially within a line section.
If ZC cannot acquire the position information of the target train, the smallest speed limit value in the RM speed limit values of the vehicle sections and the RM speed limit values of the main line sections is judged, and the smallest speed limit value is determined as the emergency braking triggering speed limit value of the target train.
In the embodiment of the invention, under the condition that the position information of the train cannot be acquired, the minimum speed limit value in the train section RM speed limit value and the main track section RM speed limit value is acquired and used as the emergency braking trigger value of the train, so that the running safety of the target train can be effectively improved.
In embodiments of the invention, if the ZC obtains the location information of the target train that the target train is completely within the train section, it obtains the train section RM speed limit as the train speed limit, and determines the train speed limit as the emergency braking trigger speed value of the target train.
The ZC obtains the position information of the target train by obtaining that the position of the head of the target train is in the train section and the position of the tail of the target train is in the train section, and the position information of the target train is that the target train is completely in the train section.
In the embodiment of the invention, the position of the target train is determined to be completely in the train section, and the emergency braking trigger speed value of the target train is adjusted to be the RM speed limit value of the train section, so that the running safety of the target train in the train section can be improved, and the safety of the whole train running system is further improved.
In embodiments of the present invention, if the location information of the target train obtained by the ZC is completely within the main track section, the RM speed limit value of the main track section is obtained as the train speed limit value, and the train speed limit value is determined as the emergency braking trigger speed value of the target train.
In embodiments of the present invention, when the running direction of the target train is the direction of exiting the train section, and the ZC obtains that the tail of the target train passes through the switch track of the main track section, it can obtain the RM speed limit value of the main track section as the train speed limit value, and determine the train speed limit value as the emergency braking trigger speed value of the target train.
The ZC obtains the position information of the target train by acquiring that the position of the head of the target train is in the main line section and the position of the tail of the target train is in the main line section, wherein the position information of the target train is that the target train is completely in the main line section.
In the embodiment of the invention, the position of the target train is determined to be completely in the main line section, and the emergency braking trigger speed value of the target train is adjusted to be the RM speed limit value of the main line section, so that the influence on the normal operation of the train due to the overhigh emergency braking trigger value can be prevented, and the potential safety hazard of the operation due to the overlow emergency braking trigger value can be prevented.

For example, when the running direction of the target train is the direction of exiting the train section, before the ZC acquires that the tail of the target train passes through the switch track of the main track section, the ZC may determine that the target train is still in the train section, and therefore still acquire the train section RM speed limit as the train speed limit, and determine the train speed limit as the emergency braking trigger speed value of the target train.
In the embodiment of the invention, under the condition that part of the target train is positioned in the main track section and part of the target train is positioned in the vehicle section, the running safety of the train can be effectively improved by determining the RM speed limit value of the vehicle section as the emergency braking trigger speed value of the target train, and further the safety of the whole vehicle running system is improved.
In embodiments of the present invention, if the position information of the target train acquired by the ZC is the direction of entering the train section, the information indicating that the deceleration operation can be performed by the MMI when the target train enters the switch track of the main track section.
In the embodiment of the invention, under the condition that the running direction of the target train is the direction of entering the train section, because the speed of the target train in the main line section is higher and the RM speed limit value of the train section is lower, the target train can be subjected to speed reduction treatment before entering the train section by utilizing the prompt information of speed reduction running of the MMI, so that the train is prevented from being subjected to emergency speed reduction after entering the train section, the running safety of the train is improved, and the safety of the whole train running system is improved.
