s101: and acquiring a bus route file and positioning information, and judging the type of an operation route according to the bus route file.
The bus line file records the type of an operation line and station information of each station of the operation line, wherein the type of the operation line comprises a single line and a double line. The positioning information is specifically GPS information, and can be acquired through a GPS module carried on a vehicle (bus), and the positioning information reflects longitude and latitude information of the position where the GPS module is located, and simultaneously reflects the longitude and latitude information of the position where the vehicle is located.

The type of the operation line comprises a single line and a double line, wherein the single line is understood as that the vehicle only runs towards a preset direction when in operation, for example, the vehicle does not run back after running from a starting point to an end point of a path (or directly returns to the starting point and then runs in a single direction), or runs along a loop line; a two-wire route is understood to mean that the vehicle is in two directions during operation, for example, a first direction from the start point to the end point of the operation route, and a reverse direction of the first direction is taken as a second direction.
In this embodiment, the operation line may include a plurality of stations, each station is provided with a different station name, and the station names between different stations are different from each other, so as to distinguish different stations in terms of naming, and meanwhile, the station positions between different stations are also different from each other.
S102: and if the type of the operation line is a single line, determining that the vehicle running direction is the direction corresponding to the single line.
Specifically, when station reporting is performed, the station reporting needs to be performed according to the positioning information and the vehicle running direction, wherein the vehicle running direction needs to be judged according to the type of the operation line. The determination of the operation line type can be judged through the operation line type recorded in the bus line file.
When the type of the service line is judged to be the single line, the vehicle can be determined to only travel towards a preset direction during service, namely the vehicle running direction is the direction corresponding to the single line. Fig. 2 is a schematic diagram of an operating line of a single-wire line of a type provided in this embodiment of the present application, and for simplicity of explanation, the diagram is described by taking 6 stations (with station names a1-a6) as an example. As shown in fig. 2, the single-wire line is a circular line and travels circularly in the direction of the arrow in the figure, and at this time, the clockwise direction corresponding to the arrow is the direction corresponding to the single-wire line, and the vehicle traveling direction can be determined to be the direction corresponding to the single-wire line.
S103: and if the type of the operation line is a double-line, determining the running direction of the vehicle according to the positioning information and the bus line file.
Illustratively, when the type of the service line is a two-line, there are two types of vehicle traveling directions, namely, an uplink direction and a downlink direction (corresponding to the first direction and the second direction, and the uplink direction and the downlink direction are defined for easy understanding or easy operation decision, that is, the correspondence between the two directions is interchangeable), where the station information includes uplink station information and downlink station information of each station in the uplink direction and the downlink direction, the uplink station information and the downlink station information both record a station name and a station position, and the stations in the uplink direction and the downlink direction are sequentially arranged according to the corresponding vehicle traveling directions.
Specifically, when the type of the operation line is judged to be a double-line, the positioning information of the vehicle is compared with the station information of each station in the bus line file, that is, the positioning information is respectively compared with the station positions in the uplink station information and the downlink station information, the station entering range where the vehicle is currently located is judged, the corresponding condition of the sequencing of the vehicle between two (or more) stations in sequence and the stations in the uplink direction and the downlink direction is judged, and when the sequence of the two (or more) stations in sequence is consistent with the sequencing of the two (or more) stations in the uplink direction or the downlink direction, the running direction of the vehicle can be judged to be the uplink direction or the downlink direction.
Fig. 3 is a schematic diagram of an operating line of a type of a two-wire line provided in this embodiment, and for simplicity of description, the operating line is described by taking an example where each of the uplink direction a and the downlink direction B includes 5 stations (the station names are respectively a11-a15 and B11-B15, where a11-a15 and B15-B11 may have the same station name, and are shown differently for convenience of illustration). As shown in fig. 3, it is assumed that the current vehicle travels in the direction of arrow C1 in the figure, at this time, it is known that the current vehicle is located within the inbound ranges of station a13 and station B13 according to the positioning information, and the stations corresponding to the inbound range of the previous station where the vehicle is located are station a12 and station B14, respectively, it is known that the sequence from a12 to a13 only satisfies the ranking in the uplink direction a, and at this time, it is determined that the vehicle travel direction is the uplink direction.
S104: and reporting the bus stop based on the vehicle running direction and the positioning information and in combination with the bus route file.
Specifically, the current positioning information is compared with the station position summarized by the station information, when the vehicle is determined to enter the station entering range, the corresponding station name is determined according to the station information corresponding to the station entering range, and the current station entering and the next station entering are reported by combining with the next station corresponding to the vehicle running direction in the bus line file, so that passengers are reminded.
The vehicle running direction can be directly determined when the running line of the vehicle is a single-line, and the vehicle running direction can be accurately determined by combining the positioning information and the bus line file when the running line of the vehicle is a double-line, and the accurate station reporting is performed by combining the vehicle running direction and the positioning information, so that the condition of station reporting errors is reduced.
Fig. 4 is a flowchart of another accurate station reporting method according to an embodiment of the present application. The accurate station reporting method is a concrete embodiment of the accurate station reporting method. Referring to fig. 4, the accurate station reporting method includes:
s201: and acquiring the bus route file and the positioning information.
The positioning information is specifically GPS information, which can be acquired through a GPS module carried on a vehicle (bus), and the GPS information is acquired according to a preset time period (such as 1s), wherein the positioning information reflects longitude and latitude information of the position where the GPS module is located, and simultaneously reflects the longitude and latitude information of the position where the vehicle is located. Optionally, when the positioning information is obtained, it is verified whether the positioning information is valid, if so, the next operation is continued, otherwise (for example, when the GPS signal is not good), the positioning information is discarded, and the positioning information is obtained again.
Further, the bus line file records the type of an operating line and station information of each station of the operating line, the type of the operating line comprises a single line and a double line, the station information comprises uplink station information and downlink station information of each station in an uplink direction and a downlink direction, the uplink station information and the downlink station information record station names and station positions, and the station positions are recorded through longitude and latitude information.
Meanwhile, the uplink site information and the downlink site information also record site serial numbers, and the site serial numbers are determined according to the sequence of the corresponding sites on the operating line, that is, the site names in the uplink site information and the downlink site information are respectively bound with the site serial numbers according to the sequence of the uplink direction and the downlink direction, and the site serial numbers corresponding to the direction along the operating line are sequentially increased.
Illustratively, the bus route file may be stored in a local or cloud server, and the corresponding storage address is accessed through a corresponding communication protocol and the bus route file is obtained.
S202: and judging whether the type of the operating line is a single-wire line. If so, go to step S203, otherwise, go to step S204.
S203: and determining the running direction of the vehicle as the direction corresponding to the single-wire line.
For example, when the service line type is determined to be a single line, it may be determined that the vehicle is only traveling in a predetermined direction during service, that is, the vehicle traveling direction is the direction corresponding to the single line. After the vehicle running direction is determined, it jumps to step S207.
S204: and judging whether the station entering condition of the starting station is met. And if so, jumping to the step S205, otherwise, jumping to the step S206.
Illustratively, when the type of the operation line is judged to be a double-line, the vehicle running direction needs to be determined according to the positioning information and the bus line file, wherein the vehicle running direction comprises an uplink direction and a downlink direction.
Further, the starting station entering condition includes an uplink starting station entering condition and a downlink starting station entering condition, which are respectively expressed as an entering range of the vehicle reaching the uplink starting station and an entering range of the downlink starting station.
In this embodiment, whether the start station entering condition is met is judged according to the positioning information and the station position of the start station in the bus route file. Specifically, according to the positioning information, the station position of the uplink starting station and the station position of the downlink starting station, a first distance and a second distance between the vehicle and the uplink starting station and the downlink starting station are calculated, and whether the first distance or the second distance is within the station entering range of the uplink starting station or the station entering range of the downlink starting station is judged to determine whether the vehicle enters the station entering range of the uplink starting station or the station entering range of the downlink starting station, so as to judge whether the uplink starting station entering condition or the downlink starting station entering condition is met.
If the first distance or the second distance is located in the station entering range of the uplink starting station or the station entering range of the downlink starting station, the vehicle is judged to enter the station entering range of the uplink starting station or the station entering range of the downlink starting station, the vehicle can be determined to meet the station entering condition of the uplink starting station or the station entering condition of the downlink starting station, and if the first distance or the second distance is located outside the station entering range of the uplink starting station or the station entering range of the downlink starting station, the vehicle is determined not to meet the station entering condition of the starting station.
It can be understood that only the uplink or downlink starting station entering condition can be satisfied at the same time, and if both conditions are satisfied, the data is considered to be abnormal, the vehicle running direction is maintained as the vehicle running direction determined last time, the current direction determination is stopped, and the process returns to step S201.
The inbound range is determined by a general preset radius (e.g., preset to 100m) and an adaptive preset radius (set according to the traffic condition of the station, e.g., preset to 50m-150m), and in this embodiment, the smaller value of the general preset radius and the adaptive preset radius is used as the inbound range.
S205: and determining the vehicle running direction according to the type of the start station entering condition which is met.
Specifically, if the type of the start station entering condition that is met is the uplink start station entering condition, the vehicle running direction of the vehicle is determined to be the uplink direction, and correspondingly, if the type of the start station entering condition that is met is the downlink start station entering condition, the vehicle running direction of the vehicle is determined to be the downlink direction. After the vehicle running direction is determined, it jumps to step S207.
S206: and determining the running direction of the vehicle according to the positioning information and the station position of each station in the bus route file.
When the starting station arrival condition is judged not to be met, determining the vehicle running direction according to the positioning information and the station positions of all stations in the bus route file, and specifically comprising the steps of S2061-S2062:
s2061: and updating the uplink cache linked list and the downlink cache linked list according to the positioning information and the station positions of all stations in the bus line file.
And when the station entering condition of the initial station is judged not to be satisfied, creating an uplink buffer chain table and a downlink buffer chain table which are respectively used for recording station serial numbers satisfying the uplink direction and the downlink direction.
Further, determining the station arrival range of the vehicle according to the positioning information and the station position of each station in the bus route file; determining the station serial numbers of corresponding uplink station information and downlink station information according to the station arrival range of the vehicle; and respectively updating the uplink buffer linked list and the downlink buffer linked list according to the station serial numbers of the uplink station information and the downlink station information.
Further, when the uplink buffer chain table and the downlink buffer chain table are updated according to the station serial numbers of the uplink station information and the downlink station information, the station serial numbers are compared with the station serial numbers inserted into the uplink buffer chain table last time, and the situation that the station serial numbers of the same station are inserted into the buffer chain tables twice before and after is avoided.
Specifically, if the station serial number is consistent with the station serial number inserted into the uplink cache linked list last time, ignoring the station serial number, otherwise, inserting the station serial number into the uplink cache linked list; if the station serial number is consistent with the station serial number inserted into the downlink cache linked list last time, ignoring the station serial number, otherwise, inserting the station serial number into the downlink cache linked list, and completing the updating of the uplink cache linked list and the downlink cache linked list in the current positioning information acquisition cycle.
In a possible embodiment, optionally, when the station sequence number is inserted into the uplink buffer linked list or the downlink buffer linked list, it is determined that the currently inserted station sequence number is compared with the previously inserted station sequence number, and if the currently inserted station sequence number is not in an increasing relationship with the previously inserted station sequence number, the corresponding buffer linked list is cleared (or the previously inserted station sequence number is cleared).
S2062: and determining the running direction of the vehicle according to the sequencing of the station serial numbers in the uplink cache chain table and the downlink cache chain table.
Specifically, after the updating of the uplink cache linked list and the downlink cache linked list is completed, whether the station serial number in the uplink cache linked list or the downlink cache linked list meets the station serial number increasing condition is judged, and if the uplink cache linked list meets the station serial number increasing condition, the vehicle running direction is determined to be the uplink direction; and if the downlink cache linked list meets the station serial number increasing condition, determining that the vehicle running direction is the downlink direction.
It can be understood that, at the same time, only the station serial numbers in the uplink buffer linked list or the downlink buffer linked list satisfy the station serial number increasing condition, and if the station serial number increasing condition is satisfied at the same time, the data is considered to be abnormal, the vehicle running direction is kept as the vehicle running direction determined last time, the direction determination of this time is stopped, and the step S201 is returned to.
S207: and reporting the bus stop based on the vehicle running direction and the positioning information and in combination with the bus route file.
The stop reporting can be carried out in a text and/or voice mode. Specifically, the step of reporting the bus stop based on the vehicle running direction and the positioning information and in combination with the bus route file comprises steps S2071 to S2073:
s2071: and determining that the vehicle enters a station arrival range corresponding to the current station according to the positioning information and the bus route file, and performing station arrival broadcasting.
Specifically, when the vehicle running direction is determined and the positioning information is effective GPS information, the station information of each station corresponding to the running direction in the bus route file is obtained, the positioning information and the distance between each station are compared, when the distance between the vehicle and a certain station is within the station entering range of the station, and the last broadcast content is the outbound broadcast of the last station in the vehicle running direction or the next station broadcast of the next station in the vehicle running direction is indicated, the inbound broadcast entering the station is indicated.
S2072: and determining the station entering range corresponding to the current station when the vehicle leaves the current station according to the positioning information and the bus route file, and performing the station exiting broadcasting.
Specifically, when the running direction of the vehicle is determined and the positioning information is effective GPS information, the station information of each station corresponding to the running direction in the bus route file is obtained, the positioning information is compared with the distance between each station, and when the distance between the vehicle and one station is larger than the station entering range of the station and the last broadcast content indicates that the vehicle enters the station to be broadcasted, the vehicle leaves the station to be broadcasted.
S2073: and determining the next station where the vehicle will enter according to the vehicle running direction and the bus route file, and broadcasting the next station.
Specifically, when the vehicle running direction is determined and the positioning information is effective GPS information, the station information of each station corresponding to the running direction in the bus route file is obtained, the positioning information and the distance between each station are compared, when the distance between the vehicle and one station is larger than the station entering range of the station, and the last broadcast content indicates the outbound broadcast leaving the station or the inbound broadcast entering the station, the next station broadcast indicating the next station of the vehicle running direction is carried out. It is understood that the combination of steps S2071-S2073 may be performed as needed for the actual stop announcement content.
