fig. 2 is a schematic view of the operation of a bus on a V-shaped road in the embodiment of the invention.
Detailed Description
For a better understanding of the nature of the invention, its description is further set forth below in connection with the specific embodiments and the drawings.
When a vehicle runs in two directions, two stations with close distances are inevitably generated under the condition that longitude, latitude and course angles are close, and the broadcasting of the stations is inconsistent with an actual running route. The route easy to misreport is a running route which is close to the actual running longitude and latitude and the course angle.
As shown in fig. 1, there is a bus stop at the vertex of the V-shaped road near the V, and at this time, if the route of the normal bus stop report is set as the uplink and the opposite direction is the downlink, when the bus runs on the downlink, the uplink stop will be reported by mistake because the uplink and downlink running latitude and longitude and the course angle are close, and the relevant vehicle-mounted display terminal is switched to the uplink. The uplink line is a line which is easy to misreport on the V-shaped road.
The invention is particularly suitable for the stop announcement when the bus runs to the V-shaped road, and comprises the following steps:
s1, starting from a vertex of a V-shaped road, extending to two branches, and easily giving false alarm to buses due to the fact that the longitude and the latitude are close and the heading angles are close. Therefore, the currently running line is set as a main line, and the line which is easy to misreport is set as a secondary line.
S2, counting each station on the subline by N { N1, N2, N3, … …, Nn }, with an initial value of N being 0, where N1 is the count at the first station in the direction of subline travel, N2 is the count at the second station in the direction of subline travel, N3 is the count at the third station in the direction of subline travel, … …, Nn is the count at the nth station in the direction of subline travel.
And S3, acquiring the real-time longitude and latitude of the bus and caching information of the uplink station and the downlink station for matching, and counting the station of the secondary line according to the matching result. The uplink and downlink station information cache comprises an uplink station forecasting range, a downlink station forecasting range and an uplink station name.
The initial value of counting is 0, and the real-time longitude and latitude of the bus is matched with the secondary line once and is recorded as 1.
And S4, reporting the bus stop according to the real-time longitude and latitude of the bus, the information cache of the uplink stop and the downlink stop and the count N of the secondary line stop.
And if the real-time longitude and latitude of the vehicle are matched with the station forecasting range of the main line, resetting the counts corresponding to all stations of the auxiliary line, and reporting the station name of the main line.
If the real-time longitude and latitude of the vehicle are matched with the forecasting ranges of the intermediate stations of the main line and the intermediate stations of the secondary line, extracting the count of the previous station of the secondary line station, if the count of the previous station is 0, broadcasting the main line station, and adding 1 to the count corresponding to the secondary line station; and if the count of the previous station is 1, broadcasting the station of the secondary line, clearing all the counts by 0, and switching the primary line and the secondary line.
And if the real-time longitude and latitude of the vehicle are matched with the initial station of the secondary line and the last station of the primary line is forecasted, adding 1 to the station count of the secondary line, broadcasting the station name of the secondary line and switching the primary line and the secondary line.
As shown in fig. 2, the directions a1 and B1 are both upward, specifically, a1 is upward south direction, and B1 is upward east direction; the directions a2 and B2 are both downward, specifically, a2 is the downward north direction, and B2 is the downward east direction.
When the bus runs in the descending north direction A2, the distance and the heading angle of the bus station are similar to those of the bus station in the ascending east direction B1, and the station in the descending north direction A2 is easily reported as the station in the ascending east direction B1.
Taking the bus running A2 line as an example, the A2 line is set as a main line, and the B1 line is a secondary line. N1 is the count of b1, N2 is the count of b2, and N3 is the count of b 3. According to the invention, the information cache of the uplink and downlink sites is added in the vehicle-mounted terminal, and the vehicle-mounted terminal is preferentially matched with the A2 line after acquiring the real-time longitude and latitude.
1. And if the real-time longitude and latitude of the vehicle are within the station forecast range of the A2 line, directly reporting the station, and clearing N1, N2 and N3.
2. And if the real-time longitude and latitude of the vehicle are matched with the forecast ranges of the a2 station of the A2 line and the B2 station of the B1 line, extracting the count N1 of the B1 station. If N1=0, broadcasting a2 station, and adding 1 to N2; if N1=1 proves that the B1 route is matched after two successive stops are matched, and the actual running route of the bus is possibly switched, the B2 stop is forecasted, the N1, the N2 and the N3 are cleared, the B1 route is switched to the main route, and the A2 route is set as the auxiliary route.
3. If the B1 station (the initial station) of the B1 line is matched and the station broadcasted before is the A3 station (the terminal station) of the A2 line, the A2 line runs out and needs to be normally switched to the B1 line, the B1 station name is broadcasted, all the counts are cleared, the B1 line is switched to the main line, and the A2 line is set as the auxiliary line.
By using the logic of the invention, if the downlink is matched with the uplink station, the station reporting system can not report the station directly, and only when two adjacent stations in the uplink are matched continuously, the station broadcasting can be carried out, and the line is switched. Therefore, when the bus passes through the V-shaped intersection, the bus can not be mistakenly reported even if an uplink line is matched, and meanwhile, the problem that the bus is in an emergency and needs to be switched from a downlink state to an uplink state can be solved.
