In one embodiment, a train normally runs in a current line according to the running electronic map data of the current line, and when a target line access exists in front of the running of the train, a control station, a monitoring system or a regional control station in a CBTC sends a line change instruction to the train, wherein the instruction comprises a line-crossing running command issued to the train and a target line access target line to be switched to; the train receives an overline operation command in the line change instruction and confirms a target line; the vehicle-mounted signal equipment receives message data sent by the ground signal control equipment control forenotice transponder group; and obtaining the electronic driving map of the target route by analyzing the message data.
As shown in fig. 2, the target route takes a forenotice transponder group B0 deployed within a certain distance (i.e. a preset distance) outside a target boundary between a current route of the train and a target route ahead of the train as an example, and the method for acquiring the driving electronic map provided by the present invention is explained in detail:
in an embodiment, when a target route existing in front of a current route of a train is an inter-route (a lateral route in fig. 2), a mode of a pre-notice transponder group is set to inform data information of the lateral route in front of the train in advance, a ground signal control device controls sending of message data of the train, and B0 is the pre-notice transponder group. When the train passes through the forenotice transponder group B0, the ground signal control equipment controls the forenotice transponder group B0 to send message data, obtains a running electronic map of a lateral route by analyzing the message data, and controls the train to run according to data information of an overline line.
In an embodiment, when there is a target route ahead of the current route of the train, which is the route of the current route (the current route) (the straight route in fig. 2), the data information of the straight route ahead of the train is notified in advance by setting a pre-warning transponder group, and the ground signal control device controls the transmission of the message data, as shown in fig. 2. When the train passes through the forenotice transponder group B0, the ground signal control equipment controls the forenotice transponder group B0 to send message data, obtains a running electronic map of a straight route by analyzing the message data, and continues to control the train to run according to the data information of the line.
In one embodiment, when a train passes through the advance notice transponder group B0, and the target route existing in front of the current route of the train is not determined to be a straight route or a lateral route, the ground signal control device controls the advance notice transponder group B0 to transmit default message data (wireless route data information). If the train does not receive the message data of the forenotice responder group B0, the train controls the train by using the line data in the original driving electronic map of the current line, and cuts off the original line data to the tail end of the track section corresponding to the responder group B1.

In order to be adapted to the driving electronic map, the message data of each transponder in the forecast transponder group is designed according to the data structure type of the driving electronic map.
In one embodiment, a train normally runs in a current line according to the driving electronic map data of the current line, and a line change instruction is sent to the train by area control equipment in the CBTC under the condition that a target line crossing route exists in front of the running of the train; the train receives a cross-line operation command in the line change instruction and confirms that the target line enters the target line; the vehicle-mounted system receives message data sent by a ground signal control device control forenotice transponder group; and analyzing the message data to obtain a data structure included in the message data, and obtaining the driving electronic map of the target route in the route of the target route according to the data structure.
According to the method for acquiring the electronic driving map, due to the fact that the data content transmitted by the transponder is limited, the data structure of the electronic driving map is redesigned, so that a train can acquire all line data within a certain distance in front, and the safety of train cross-line operation is guaranteed.
Further, in one embodiment, the predictive transponder bank includes a plurality of transponders, wherein at least one of the plurality of transponders is an active transponder.
Further, in one embodiment, the driving electronic map is stored in advance in each transponder in the forecast transponder group, and each transponder stores the driving electronic map of a section of line in the target line.
Optionally, in order to avoid line data loss caused by transponder loss, redundant configuration needs to be performed on the transponders, because the storage space of a single transponder is limited, storage is performed in a manner that a plurality of transponders constitute a forecast transponder group, and when the capacity of the forecast transponder group cannot meet the requirement, the number of transponders in the group is increased.
In one embodiment, each transponder in the predictive transponder group stores an electronic map of the trip of a segment of the line. For example, if the route length of a target route ahead of the current route of the train is 1 km, a forenotice transponder group is formed by arranging two transponders, and each transponder stores a running electronic map of a section of the route, for example, 500 meters.
It should be noted that at least one of the plurality of transponders included in the forecast transponder group is an active transponder.
The active transponder has a special transponder cable connected with the ground electronic unit, the transponders are mounted beside the annunciator, and the active transponder has cable connection at other places of the subway line according to the condition, so that the stored information in the active transponder can be changed in real time according to the requirement.
In one embodiment, considering the situation of train reverse operation, the forecast responder group needs to store the driving electronic map in the reverse operation at the same time. When the train passes through the forecast responder group without positioning, the vehicle-mounted signal equipment needs to consider receiving the message data sent by the forecast responder group in forward operation and reverse operation.
According to the method for acquiring the electronic driving map, the problem that the electronic driving map of the line data in the route of the target line cannot be stored due to the fact that the storage space of a single transponder is limited is solved by setting the transponder group.
Further, in an embodiment, the method may further specifically include:
and when the train runs to a target boundary of the current route and the target route, controlling the train according to the driving electronic map.
Optionally, taking an example that the train needs to cross the line 1 time on 2 lines, the specific steps are as follows:
in the CBTC, a train to be operated stops in the garage, and its current route is acquired from the train operation shift schedule as route 1.
The train stores the downloaded driving electronic map of the line 1 in the memory partition 1 of the vehicle-mounted signal device, if the previous memory partition 1 is not empty, the driving electronic map data of the line 1 may be stored into the vehicle-mounted electronic map data after the memory partition 1 is empty, or when the memory partition 2 is a blank partition although the memory partition 1 is not empty, the driving electronic map data of the line 1 may be stored into the blank memory partition 2 first, and then the memory partition 1 is emptied after receiving a line crossing command, in this embodiment, it is assumed that the driving electronic map data of the line 1 is stored into the memory partition 1.
During the normal operation of the train in the line 1, determining that a target line access existing in front of the line 1 is a line 2, and receiving a line change instruction sent to the monitoring system in the CBTC, wherein the line change instruction comprises a line crossing operation command issued to the train and the line 2 to be switched to; the train receives the line-crossing operation command in the line change command and confirms the line 2.
Because the train is in a normal running state at present, in order not to affect the normal processing function of each cycle of the vehicle-mounted system, before the train runs to the target boundary between the line 1 and the line 2, the message data sent by the forecast transponder group is obtained, and the running electronic map of the line 2 is obtained by analyzing the message data, and specifically, the running electronic map data of the line 2 can be stored in the memory partition 2.
When the train reaches the target boundary between the line 1 and the line 2, the train is locked to enter the line 2 to run, and the train is controlled to run according to the electronic running map in the memory partition 2, so that seamless cross-line running is realized.
According to the method for acquiring the driving electronic map, the data structure of the driving electronic map is re-planned and designed, and the ground responder is used for storing the driving electronic map data, so that the interconnection and intercommunication of urban rail transit and cross-line operation are more flexible and convenient.
