The technical scheme of the invention is described in detail below by taking a computer to execute the method for dividing the train electronic map provided by the invention as an example.
The MA (Moving Authorization, driving permission) of the train refers to a start command of the train operation, and the command includes information such as a distance of the train operation, a start point and an end point of a train operation range, a speed of the train operation, and an obstacle of the operation range, and is a driving certificate of the train safe operation.
In step S110, if it is determined that the train is running in the urban area route all the time, as shown in the schematic diagram of running of the train in the urban area route provided in fig. 2, and no switching of the running route is involved, that is, if the driving range of the train MA is the urban area route area, the route data of the MA range in the electronic map of the train is divided, and the driving electronic map of the train is obtained.
It can be understood that the electronic map of the driving permission range is obtained according to the original structure in the electronic map of the train, namely, the line data in the MA range is cut off to form a new electronic map, and the electronic map of the whole line of the line and the newly generated electronic map have the following relationship:
B N ∈A o (1)
wherein A is o Is an electronic map of the train, namely a line data set of the whole line of the line, B N For the newly generated line data set.
By means of a driving electronic map acquisition mode of dividing the electronic map of the train according to the driving range of the MA, timely updating of the electronic map can be achieved. Meanwhile, the amount of each update is smaller, the occupation of communication is smaller, and the system resources are saved.
In step S120, in the case where the driving range of the train MA includes a city line area and a non-city line area, as shown in the schematic diagram of the cross-line operation of the train provided in fig. 3, that is, in the case where the driving range of the train MA includes a switching between the city line area and other line areas.

The data volume of the electronic map after segmentation is smaller than that of the electronic map before segmentation, so that the data volume of each update of the train is smaller, the occupation of communication is smaller, and the system resources are saved. Meanwhile, when the train is in cross-line operation, different electronic map acquisition modes are adopted according to different line modes, so that the problem of acquiring line data in the train operation in different line modes is solved.
In one embodiment, dividing the electronic map of the train according to the driving range of the MA to obtain the driving electronic map of the train includes: according to the driving range of the MA of the train, according to the original data structure of the electronic map of the train, MA range line data of the electronic map of the train in the driving range of the MA are obtained; and forming the MA range line data into a new electronic map as a driving electronic map of the train.

And recombining the intercepted line data, and taking the recombined line data as a train driving electronic map.
It will be appreciated that the range of the train MA is dynamically updated during the train's travel. After the electronic map of the train is divided according to the MA driving range of the train, the driving electronic map of the corresponding MA driving range is only required to be downloaded in the driving process of the train, and the dynamic downloading of the driving electronic map of the train is realized. The data volume of the running electronic map of the divided train is smaller than that of the original train, and after the MA range is dynamically updated each time, the updated running electronic map is small in data volume, so that the occupation of communication is small, the processing efficiency of the vehicle-mounted control system is improved, and the system resources are saved.

In one embodiment, in a case where the end of the driving range of the MA is between two axle meters, the driving electronic map contains information of the two axle meters.
In the updating process of the MA, the situation that the end point of the MA is between two axis meters often occurs, and at this time, the segmented electronic map data should contain two axis meter information where the end point of the MA is located. As shown in the dividing schematic diagram of MA driving range end data provided by the invention in FIG. 4, the divided electronic map data should contain all information of the axle counter JZ2 and JZ 3.

if the line data of the CBTC line is stored in the vehicle-mounted system in the form of a full-line electronic map, converting the line data in the non-urban line area into line data in the form of electronic map data of the urban line area. Meanwhile, the converted line data in the CBTC range and the line data in the city domain range can be spliced to form complete line data in the MA range, and the continuity of line data transmission in the MA is ensured.
If the CBTC line adopts the same line data updating mode as the urban line, the line data in the non-urban line area is converted into line data in the form of electronic map data of the urban line area. Meanwhile, the converted line data in the CBTC range and the line data in the city domain range can be spliced to form complete line data in the MA range, and the continuity of line data transmission in the MA is ensured.
