The GPS global positioning system 1 provides the location of the vehicle 2 and transmits the information to the station detection and broadcast unit 3 for calculation. The result is reported back to the station information management platform 5 via the wireless communication network 4.

The station detection and broadcast unit 3 includes five modules, as shown in Figure 2. A wireless communication module 31 is responsible for returning the location of the vehicle and the status of the entry and exit station to the station information management platform, providing information as a follow-up application; a satellite positioning module 32, obtaining the current location of the vehicle through the global positioning system; The bit detection module 33 compares the processed route location data with the satellite positioning data and determines the status of the incoming and outgoing stations, and stores the result in the data storage module 34; a data storage module 34 stores the pre-processed station The location data and the state of the stored vehicle are read by other modules; the one-station broadcast module 35 can play the arrival information and the arrival information of the next station by means of text, video, sound or light.

The station detection method is centered on each station in the pre-processed station data. Different functions divide the detection area, and use the GPS positioning of the location of the vehicle to compare with the area drawn by each station to confirm whether the vehicle enters the site. In order to avoid the error of repeatedly triggering the entry and exit status caused by the GPS positioning drift, and depending on the terrain and application of the detected station, the detection range and size of the inbound area and the outbound area are different to solve this problem, as shown in Figure 3. As shown, the bus stop is used as the detection center, the inbound range is the radius rin meter, and the outbound range is rout meters. The two concentric circles detect the inbound and outbound stations, and the rin and rout can be dynamically adjusted according to actual needs.

In order to accurately detect the stations of different road conditions, the present invention classifies the stations according to different road conditions and broadcast modes, and the station classification can be divided into physical stations and virtual stations; the main function of the physical stations is to return to the back end. As a function of monitoring, the platform is divided into four types, the first one, broadcasting the information to the station and the next station, reminding passengers to get on and off the vehicle; the second type is not broadcasting to the station, only for passengers to get on the bus; the third, starting station, Provide the back-end platform as the route start or complete route judgment; the fourth one is a special case, which must be used in conjunction with the virtual site, and the subsequent instructions.

The virtual station is mainly known in advance for possible misuse, as a function of station consumption, in order to avoid returning incorrect information. The virtual station is divided into two types. The first type is the virtual position for consumption. As shown in Figure 4, the road conditions of the bypass, circulation line or the original road are returned. When the route is driven, the opposite lane may trigger the site or just Passing through the unreserved site, using the virtual site for station consumption, at this time, it does not report the inbound and outbound stations, nor broadcast any station information; the fourth physical station and the second virtual station are applied to the upper and lower national highways or The purpose of the station is too far away, in order to avoid the passengers' cognitive confusion caused by too early broadcast of the next station, the fourth physical station is applied to the last station before the national road; only a single station information is broadcast. Do not do the next station information broadcast. The second type of virtual station is to complement the station where the fourth entity station does not report the information of the next station, and is applied to establish a virtual station before the national highway has not arrived at the next entity station. Report the next physical station information and remind the passengers of the upcoming arrival information. As shown in Figure 5.

As shown in Figure 6, the station detection and broadcast procedure is as follows: A. The satellite positioning module 32 in the station detection and broadcast unit is used to periodically receive the vehicle satellite positioning information as a basis for subsequent operation comparison; B.
