Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Along with the sudden increase of the number of passengers on the subway, the passengers can get off the subway in a relatively poor experience sense when arriving at the station, especially in the early peak and late peak periods, the passengers often cannot see or cannot hear the information of the station, and the passengers can get off the station, or the passengers miss the getting off time due to overcrowding and then get on the station.

In order to avoid the above-mentioned situation of sitting over, passengers need to pay attention to the arrival information of the subway all the time, which requires much effort for passengers with long travel. Instead of spending energy on arriving information all the way to the subway, passengers may wish to do something in the neutral position of the ride, such as learning, working, relaxing, etc. Therefore, the arrival prompting method is provided, a user (namely a passenger) can set a task of arrival prompting on a portable terminal, the terminal locates the current station where the terminal is located, and when the current station is a terminal station or a transfer station set by the user, a prompt is sent. Therefore, the user can do some things in the free space of taking a bus, but not pay attention to the arrival information of the subway all the time, and only get off the bus when the terminal gives a prompt.

Generally, a terminal may employ Location-Based Services (LBS) to locate a current site where the terminal is located. The LBS may be a Positioning service provided by a Global Positioning System (GPS), a Global NAvigation Satellite System (GLONASS), a beidou Satellite NAvigation System, or the like, or a Positioning service provided by an Assisted Global Positioning System (AGPS), or a mobile base station Positioning service, or a Wireless (WiFi) Positioning service.

The implementation manner of determining the site where the first terminal is located is an implementation manner under the premise that different sites are determined from the first site and the at least one second site; if the first station and the second station are the same station, the first station or the second station is directly determined as the station where the first terminal is located.

In summary, in the station identification method provided in this embodiment, while the first terminal locates the current station where the first terminal is located, the first terminal also obtains information of the current station located by the second terminal from the second terminal located at the same station; and then, the current site where the first terminal is located is determined by integrating the first site information obtained by self-positioning and the second site information obtained by positioning of the second terminal, and the current site where the first terminal is located is more accurately identified through the cooperative positioning of the second terminal and the current site where the first terminal is located.

The first terminal can determine a plurality of candidate riding routes based on the starting station and the terminal station, and the riding route is selected from the candidate riding routes by the user.

In other embodiments, in a case where the first terminal cannot perform station location by itself (including a case where the second terminal does not have a station location function), the station information is provided by the second terminal, and the first terminal receives the second station information from the second terminal in the communication system shown in fig. 3, and then determines the station where the first terminal is located based on the second station information.

Optionally, the second terminal includes at least two, and correspondingly, the second site information includes at least two, and each piece of the second site information includes the second site identifier. The second site identifiers contained in the different second site information are different, that is, the sites where the plurality of second terminals are located are different sites; and/or the second station identifications contained in the different second station information are the same, that is, the stations located by the plurality of second terminals are different stations.

And step 320, determining the station where the first terminal is located based on the second station information.

Optionally, the second site information includes a confidence level (i.e., a second confidence level) of the second site, and when the second site includes at least two sites, the first terminal determines, based on the confidence level of the second site, the second site with the highest confidence level as the site where the first terminal is located.

The application provides a positioning mode of a station, combines multiple positioning and auxiliary means to realize accurate positioning of a terminal, can obtain a better positioning effect under the weak network environment of a subway, and can provide accurate, timely and effective arrival reminding service for users under different situations.

When a user swipes a card through a subway gate using terminal equipment, triggering a reminding service; the reminding service reminds the user to set a destination site, and can also recommend the destination site for the user by combining the user travel time period and the historical record; calculating a riding route and a transfer station according to a destination station and a subway running line; if a plurality of transfer schemes exist, preferentially recommending the best scheme, and providing the rest schemes for the user to select; calculating a transfer station through a destination station and a riding scheme; bringing the transfer site and the target site into a reminding site set; when the user arrives at the previous station of the reminding station, reminding (such as pop-up window, notification, ring, vibration and the like) is carried out on the user, and secondary reminding can be carried out on the user when the user arrives at the reminding station; and the user finishes the reminding service by swiping the card when going out of the station.

When a user just enters a gate, the user can be assumed to enter an indoor subway station from the outdoors, and because the positioning result precision of the outdoor positioning service is higher and more accurate, it can be assumed that the positioning data of the user is relatively accurate within a period of time when the user just enters the subway station, and the reliability (namely, the confidence) of the user is set to be high. After entering the subway for a period of time, due to the special operating environment of the subway, the positioning result error generated by the positioning service becomes large, so that the reliability of the positioning result error is set to be low.

The specific method for locating the current station by the single device is as follows:

1) The equipment judges whether the station arrives or not through the IMU, and obtains the current station information IMU _ station by combining the train running line; since the motion sensor data error is large, its confidence level is set low;

2) The equipment judges whether the station arrives or not through audio recognition, and obtains the current station information ASR _ station by combining with the train running line; setting the credibility of the audio frequency to be low and medium according to the audio frequency quality and the confidence coefficient of the recognition result (the audio frequency quality is clear, the confidence coefficient of the recognition result is high, the confidence coefficient is medium, otherwise, the confidence coefficient is low);

3) The equipment obtains current position information through positioning service and obtains current station information LBS _ station by combining with a train running line; setting the credibility of the terminal to be high or low according to the time length of the terminal on the subway (the credibility is high within a period of time just entering the subway, and the credibility is low after a certain period of time is exceeded);

4) Making a decision on the obtained result, and preferentially selecting the result with high reliability as a final result; if a plurality of results with consistent credibility exist, selecting the result with the highest vote number as a final result in a voting mode; if a plurality of results with consistent credibility, consistent ticket number and inconsistent result exist, sorting the results according to the credibility of the source (such as Vote _ state > LBS _ state > IMU _ state > ASR _ state, and recording the voting result as Vote _ state), and preferentially selecting the result with high source credibility as a final result; recording a source and a reliability corresponding to the positioning result;

the above positioning modes 0 to 0 may be increased or decreased, or other combinations may be used, and are not particularly limited.

As shown in fig. 5, the specific way of sharing and locating the current station by multiple devices is as follows:

taking the devices a and B as an example for explanation, the device a is already on the subway and the device B is going to get on the subway at the subway station platform.

When the device A is on the subway, the positioning result of the device A is A _ ASR _ station1, the source is ASR, and the reliability is low. The device A externally broadcasts the self-positioning result, source and credibility.

The device B obtains the specific station information B _ LBS _ station1 at the subway station through the positioning service, the source is the positioning service, and the reliability is high. And the device B scans and broadcasts the obtained positioning result, source and credibility by using Bluetooth.

Both the devices a and B acquire the site information broadcast by the other party. For example, the location information obtained by the device a is [ (a _ ASR _ station1, ASR, low), (B _ LBS _ station1, LBS, high) ], and by comparing the degrees of reliability, the B _ LBS _ station1 is selected as the current station information. So that each device obtains consistent station information B _ LBS _ station1.

And if a plurality of results with consistent credibility exist, the decision and fusion of the results are realized by the method mentioned in the step 0 of the single-device positioning fusion mode.

When the device C appears, the device C repeats 1 and enters the subway. And synchronizing information with A and B. A. B, C gets the next station information C _ LBS _ station2. The devices a, B and C can calculate the current subway line and direction through the station sequences [ B _ LBS _ station1, C _ LBS _ station2 ]. Based on the monitoring, the traveling route of the user is monitored, and if the user deviates from the route, the user is reminded.

The method does not require different devices to have the same positioning means, and each device can select the positioning mode according to the software and hardware capability of the device and then perform fusion decision with the positioning capability of other devices. For example, the a device is a watch/bracelet, which can only be positioned by a motion sensor; and the B device is a mobile phone, which can realize positioning by using positioning service, a motion sensor, audio identification and other modes.

By the method, the sharing of the positioning information of a plurality of devices can be realized, and only the devices are provided with the Bluetooth modules. For the device which does not have the positioning function or the motion sensor, the device positioning and arrival reminding functions can be realized through sharing of other devices.

In the weak network environment (usually occurring in the morning and evening rush hour), the positioning and network delay is increased, and the error of the positioning result is increased. If a plurality of devices exist at the same time, the correction of the positioning result can be realized through the sharing of the positioning result among the devices. Meanwhile, the frequency of calling the positioning service by the equipment can be properly reduced, and the positioning information is obtained through the broadcast of other equipment, so that the increase of the power consumption of the equipment caused by frequently calling the positioning service is avoided.

Under extreme conditions (weak network environment and no other devices are present), the device can also realize more accurate positioning results through the fusion of the positioning results of multiple self positioning modes, thereby realizing the arrival reminding service.
