Problems solved by technology

This type of automatic station reporting technology overcomes the existing false station reporting situation caused by direct use of Euclidean distance, but it needs to calculate the distance between the vehicle and all stations in real time, which requires a large amount of calculation, and it needs to analyze the changing trends of different lines in the early stage to obtain the basis for judgment , which realizes complex high

Embodiment 1

[0038] The embodiment of the invention discloses a method for automatic bus station announcement, such as figure 2 shown, including the following steps:

[0039] S01, using the last reporting site as a reference site.

[0040] Generally, station announcement information includes at least line direction, station serial number, station ID, and station announcement time.

[0041] S02, judging whether the geographical distance of the vehicle from the reference station in the running direction of the designated line, the time distance between the current running time of the vehicle and the time of the last reporting time of the vehicle satisfies any of the following conditions:

[0042] (1) The geographical distance is not greater than the reporting radius of the reference station;

[0043] (2) The time distance is not greater than a preset time.

[0044] Specifically, calculating the geographical distance that the vehicle leaves the reference site includes: finding the latitud...

Embodiment 2

[0094] In some embodiments, the embodiment of the present invention also discloses a remote server 10, combined with image 3 As shown, the remote server 10 includes a bus route data storage module 11, a scheduling information module 12, a cache module 13, and a site judgment module 14, wherein:

[0095] The bus route data storage module 11 is used for storing the station information corresponding to each bus route ID, and accepts the station information request instruction of the station judging module 14, and provides the required station information to the station judging module 14. Table 1 shows the content of the station information, including at least the route direction, station number, station ID, station latitude and longitude information, and station reporting radius. The line direction includes uplink or downlink, and the line direction of the ring line can be regarded as only one direction, such as uplink. The station IDs of stations with the same name in the upli...

Embodiment 3

[0116] In some embodiments, a bus automatic station announcement system is disclosed, such as Figure 4 As shown, it includes the vehicle-mounted terminal 20 located on the bus, and the remote server 10 installed on the side of the bus group management system. The remote server 10 and the vehicle-mounted terminal 20 have a one-to-many relationship. in:

[0117] The vehicle-mounted terminal 20 is used to send the acquired vehicle actual operating state information to the remote server 10; for receiving vehicle scheduling information and station announcement information; also for performing station announcement according to the station information; the actual operating state information of the vehicle is at least Including the vehicle ID, the current latitude and longitude information of the vehicle, and the current running time of the vehicle. The vehicle dispatching information generally comes from the dispatching system of the public transport group, and at least includes the...

Abstract

The invention discloses an automatic bus stop announcement method and system and a remote server. The method comprises the following steps: taking the previous bus stop announcement station as a reference station, judging whether the geographical distance of a vehicle leaving the reference station in the running direction of a specified line and the time distance between the current running time of the vehicle and the previous bus stop announcement time meet conditions or not, and if so, determining that the serial number of a station to-be-reported is equal to the serial number of the reference station plus 1; and if not, taking the next station of the reference station as the reference station, continuing to judge whether the geographical distance and the time distance meet the conditions or not, then obtaining the ID of the station to-be-reported according to the serial number of the station to-be-reported and the running direction of the line, and generating bus stop announcement information when the geographical distance between the vehicle and the station to-be-reported meets the bus stop announcement radius of the station to-be-reported. According to the method, the to-be-arrived stations are sequentially searched according to the station sequence; once the to-be-arrived stations are found, the geographic distance and the time distance between the subsequent stations andthe vehicle are not calculated anymore, so that bus stop announcement skipping conditions are avoided, and the calculated amount is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent public transport, in particular to a method and system for automatic bus stop reporting and a remote server. Background technique [0002] The bus automatic station reporting system of prior art mainly comprises two classes: [0003] (1) A vehicle-mounted terminal is installed on the bus, and a GPS (Global Positioning System, Global Positioning System) module is installed in the vehicle-mounted terminal, and the latitude and longitude information of each bus station is also stored in advance. In the actual driving process, compare the real-time position coordinates of the vehicle obtained in the GPS module with the latitude and longitude information of each bus stop, calculate the Euclidean distance between the vehicle and the bus stop, and trigger when the distance meets the preset threshold Announce station. For some special lines, such as figure 1 The U-shaped line shown (the correct pat...
