Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, the first preset time may be referred to as a second preset time, and similarly, the second preset time may be referred to as a first preset time, without departing from the scope of the present application. The first preset time and the second preset time are both preset times, but are not the same preset time.

Referring to fig. 1, fig. 1 is a schematic diagram of an application environment of a method for identifying site information in an embodiment. As shown in fig. 1, the application environment includes an electronic device 110 and a terminal 120.

The terminal 120 of the present embodiment is configured to measure a wireless network change characteristic. The electronic device 110 performs the steps of the station information identification method according to any embodiment of the present application by using the wireless network variation characteristics measured by the terminal 120, so as to identify the station information of the public transportation means.

It should be noted that, in one embodiment, the terminal 120 and the electronic device 110 are the same device. That is, the electronic device 110 measures the wireless network change characteristic by itself and identifies the station information through the self-measured wireless network change characteristic.

It can be understood that, when the terminal 120 and the electronic device 110 are the same device, the electronic device 110 may measure the wireless network change characteristic by itself, and may identify the station information through the self-measured wireless network change characteristic, which is equivalent to identifying the station information through one electronic device 110, and does not need to rely on other devices, thereby improving the adaptability of station information identification.

It should be noted that, in one embodiment, the terminal 120 may be a device that is permanently fixed in a public transportation vehicle, and the terminal 120 is specifically configured to measure the wireless network change characteristic, so as to transmit the wireless network change characteristic to the electronic device 110, so that the electronic device 110 uses the wireless network change characteristic to identify the station information.

It can be understood that, by fixing one terminal 120 in the public transportation vehicle for a long time, each electronic device 110 on the public transportation vehicle can obtain the wireless network change feature through the fixed terminal 120, so as to identify the arrival information, only a flow code of the identification method of the station information needs to be configured on the electronic device 110, which reduces the ease of identifying the station information, and meanwhile, the electronic device 110 does not need additional resources to measure the wireless network change feature, which reduces the used resources of the electronic device 110.

It is noted that in one embodiment, the terminal 120 may be an electronic device other than the electronic device 110. Specifically, a plurality of passengers generally exist on a train, and each passenger generally carries an electronic device 110, so that the electronic device 110 of a certain passenger can also be used for identifying the station information by acquiring the wireless network change characteristics measured by other electronic devices of other passengers.

It can be understood that the wireless network change feature is obtained through other electronic devices of other passengers on the same train, and when the electronic device 110 cannot normally obtain the wireless network change feature, the wireless network change feature can be obtained through other electronic devices, so that the effectiveness of station information identification is improved.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for identifying site information according to an embodiment. The method for identifying site information in this embodiment is described by taking the electronic device 110 in fig. 1 as an example. As shown in fig. 2, the identification method of the station information in one embodiment includes steps 210 to 230.

And step 210, acquiring the wireless network change characteristics measured by the terminal in the public transport means.

The public transportation means refers to a vehicle, a ship, or the like for passengers to take in the public transportation. Specifically, the public transportation means of the present embodiment includes, but is not limited to, rail trains (such as subways, high-speed rails, trains, etc.), buses, etc., and is not limited herein. The wireless network change characteristic refers to a change characteristic of the wireless network measured by the terminal, and is used for representing the change condition of the wireless network.

And step 220, identifying the arrival event of the public transport means according to the wireless network change characteristics.

Wherein the arrival event refers to an event in which the public transportation arrives at a stop on the travel route. In this step, the identification of the arrival event is achieved through a wireless network change feature. Specifically, when an arrival event occurs in the public transportation, the public transportation is considered to arrive at a station.

And step 230, in the case that the arrival event is identified, identifying the station information on the driving route of the public transportation means through the arrival event.

Here, the station information refers to information on stations on the travel route of the public transportation. The site information of this step is identified by an arrival event. Optionally, the station information includes, but is not limited to, whether the public transportation means arrives at a station, whether the public transportation means arrives at a destination station, a station where the public transportation means is currently located, a transit station of the public transportation means, and the like, and is not limited herein.

According to the technical scheme of the embodiment, the electronic device is used for identifying the arrival event of the public transport by utilizing the wireless network change characteristics, so that the station information of the public transport is identified through the arrival event, and the station information of the public transport can be identified through the electronic device, namely the electronic device replaces passengers to pay attention to the station information, so that the station information can be identified even if the passengers pay attention to the station information, and the technical effect of paying attention to the station information of the public transport in real time is achieved.

The following embodiments explain how to identify the arrival time of the public transportation means according to the wireless network variation characteristics on the basis of any of the above embodiments.

In one embodiment, identifying the arrival event of the public transportation vehicle from the wireless network change characteristic comprises:

identifying whether a group of door opening and closing events occur in the public transport means according to the wireless network change characteristics, wherein first interval time between the group of door opening events and the group of door closing events is less than first preset time; if the public transport means is identified to generate a group of door opening and closing events, detecting whether the public transport means keeps a door opening state between the group of door opening events and the group of door closing events; and if the public transport means is detected to keep the door opening state between a group of door opening events and door closing events, determining that the public transport means has the arrival event once.

Referring to fig. 3, fig. 3 is a second flowchart illustrating a method for identifying site information according to an embodiment. In one embodiment, as shown in fig. 3, the method for identifying site information includes steps 310 to 350.

And step 310, acquiring the wireless network change characteristics measured by the terminal in the public transport means.

This step may refer to the description of any of the above embodiments, which is not repeated herein.

And step 320, identifying whether a group of door opening and closing events occur in the public transport means according to the wireless network change characteristics.

In this step, a first interval time between door opening events and door closing events of a group is less than a first preset time. The first preset time may be set as required, for example, the interval time between a group of door opening events and door closing events during the driving process of the public transportation vehicle may be counted, and the first preset time may be determined according to the counted interval time. In this step, if it is recognized that a group of door opening and closing events occur in the public transportation means, step 330 is performed. In one embodiment, step 310 is optionally performed if a set of door opening and closing events for the public transportation vehicle is not identified.

In this step, specifically, the door opening event and the door closing event of the public transportation are identified according to the wireless network change characteristics, and it is determined whether a first interval time between the door opening event and the door closing event is less than a first preset time, and if it is determined that the first interval time between the door opening event and the door closing event is less than the first preset time, the door opening event and the door closing event are determined as a group of door opening and closing events.

Step 330, detecting whether the public transportation vehicle maintains the door opening state between a set of door opening events and door closing events.

In this step, if it is detected that the public transportation vehicle maintains the door-open state between a set of door-open events and door-close events, step 340 is performed. In one embodiment, step 310 is optionally performed if it is detected that the public transportation vehicle does not maintain the door open state between a set of door open events and door close events.

Step 340, determining that the arrival event occurs once in the public transportation means.

In the step, if a group of door opening and closing events of the public transport means are identified according to the wireless network change characteristics, and the public transport means is detected to keep the door opening state between the group of door opening events and the group of door closing events, the public transport means is determined to have a station arrival event.

And 350, under the condition that the arrival event is identified, identifying the station information on the driving route of the public transport means through the arrival event.

According to the technical scheme of the embodiment, whether a group of door opening and closing events occur in the public transport means is identified through wireless network change characteristics, and whether the door opening state of the public transport means is kept between the group of door opening events and the group of door closing events is detected when the group of door opening and closing events occur in the public transport means is identified, so that when the door opening state of the public transport means is detected to be kept between the group of door opening events and the group of door closing events, the public transport means is determined to have a station arrival event.

In some cases, for example, there may be some cases of temporary stopping in the middle of the train during traveling, and the temporary stopping in the middle may be mistakenly recognized as an arrival event, so that such abnormal cases need to be eliminated. In general, since the temporary stop is generated between two stops, if the temporary stop is generated in the middle, the interval time between two adjacent arrival events is short, and thus whether the arrival time is accurately identified can be identified by the interval time between two adjacent door opening and closing events.

In one embodiment, the method for identifying station information further includes:

acquiring a second interval time between two adjacent arrival events;

and if the second interval time is less than the eighth preset time, recording two adjacent arrival events as one arrival event.

In the present embodiment, the second interval refers to an interval between two adjacent arrival events. The eighth preset time may be set as needed, and this embodiment is not limited. Specifically, the eighth preset time is generally less than the average running time of two adjacent sites. If the second interval time is less than the eighth preset time, it may be considered that the two adjacent arrival events are one of the two adjacent arrival events, where the one arrival event is a false recognition of the arrival event caused by the temporary stop in the middle of the vehicle, and therefore the two adjacent arrival events are recorded as one arrival event.

According to the technical scheme, the second interval time between two adjacent arrival events is obtained, and if the second interval time is smaller than the eighth preset time, the two adjacent arrival events are recorded as the one arrival event, so that the problem of mistaken identification of the arrival event due to the fact that a public transport vehicle stops temporarily in the driving process is solved, and the accuracy of identifying the times of the arrival event is improved.

In one embodiment, optionally, the wireless network variation characteristic comprises at least one of a first variation characteristic of doppler shift and a second variation characteristic of wireless signal strength.

Among them, doppler Shift (Doppler Shift) refers to a change in phase and frequency due to a propagation path difference when a mobile station moves in a certain direction at a constant velocity, and such a change is generally called Doppler Shift. It reveals the law that the wave properties change during motion. When moving in front of the wave source, the wave is compressed, the wavelength becomes shorter, and the frequency becomes higher (blue shift); when the motion is behind the source, the opposite effect occurs, the wavelength becomes longer and the frequency becomes lower (red shift). The wireless signal strength refers to the strength of the wireless signal.

Since it is necessary to identify the door opening event and the door closing event of the public transportation in the process of identifying the station arrival event, the following embodiments are explained on the basis of any of the above embodiments on how to identify the door opening event and the door closing event of the public transportation according to the wireless network change characteristics.

In one embodiment, the step of identifying a door open event for the public transportation vehicle based on the wireless network change characteristic comprises:

if the first change characteristic is that the Doppler frequency shift changes from high to low within a second preset time, determining that a door opening event occurs in the public transport means, and/or;

and if the second change characteristic is that the wireless signal intensity of the same service cell changes from low to high within a third preset time, determining that a door opening event occurs in the public transport means.

In this embodiment, the second preset time may be set according to needs, and is not limited herein as long as the second preset time can reflect the abrupt change process of the doppler shift. Specifically, when the public transport means runs at a high speed, the Doppler frequency shift of wireless signal transmission is larger, and when the subway runs at a reduced speed or stops, the Doppler frequency shift is smaller, so that whether the door opening event occurs in the public transport means can be determined according to the change condition of the Doppler frequency shift. Specifically, when determining whether a door opening event occurs in the public transportation means by using the doppler shift is equivalent to detecting that the public transportation means stops, it is considered that a door opening event occurs. The Doppler frequency shift is utilized to identify the door opening event, so that the condition that the train door cannot be normally opened to cause the condition that the arrival event cannot be identified can be avoided.

In this embodiment, the third preset time may be set according to needs, and is not limited herein as long as the third preset time can reflect the abrupt change process of the wireless signal strength. Specifically, after the public transport vehicle opens the door, the wireless signal intensity measured by the terminal is suddenly strengthened because of no shielding of the door, the strengthened signal intensity is kept stable and unchanged in the opening state of the door, and when the door is closed, the wireless signal intensity measured by the terminal is weakened because of shielding of the door, so that whether the public transport vehicle has an opening accident or not can be determined according to the change condition of the wireless signal intensity. The door opening event is identified by using the wireless signal, so that the condition that the arrival event identification is abnormal due to temporary parking of the public transport means can be avoided.

It should be noted that, if the wireless network change characteristic includes a first change characteristic of a doppler shift and a second change characteristic of a wireless signal strength, when the doppler shift changes from high to low within a second preset time and the second change characteristic of the wireless signal strength of the same serving cell changes from low to high within a third preset time, it is determined that a door opening event occurs in the public transportation.

According to the technical scheme of the embodiment, because both the Doppler frequency shift and the wireless signal strength can reflect the door opening and closing event of the public transport vehicle, the door opening and closing event of the public transport vehicle can be identified through at least one of the first change characteristic of the Doppler frequency shift and the second change characteristic of the wireless signal strength, and therefore the arrival event is identified. It can be understood that the identification of the door opening and closing event is performed through the doppler frequency shift and the wireless signal strength, the blind area of the identification of the doppler frequency shift and the wireless signal strength can be compensated, the effect of 1+1 > 2 can be achieved, and the accuracy of the identification of the arrival event is improved.

In one embodiment, the step of identifying a door closing event for the public transportation vehicle based on the wireless network change characteristic comprises:

if the first change characteristic is that the Doppler frequency shift changes from low to high within a fourth preset time, determining that a door closing event occurs in the public transport means, and/or;

if the second change characteristic is that the wireless signal intensity of the same service cell changes from high to low within a fifth preset time, determining that a door closing event occurs in the public transport means.

In this embodiment, the fourth preset time may be set according to needs, and is not limited herein as long as the fourth preset time can reflect an abrupt change process of the doppler shift. Similarly, the fifth preset time may be set as needed, and is not limited herein as long as the fifth preset time can reflect the abrupt change process of the wireless signal strength.

It should be noted that, if the wireless network change characteristic includes a first change characteristic of a doppler shift and a second change characteristic of a wireless signal strength, the first change characteristic is that the doppler shift changes from low to high within a fourth preset time, and the second change characteristic is that when the wireless signal strength of the same serving cell changes from high to low within a fifth preset time, it is determined that a door closing event occurs in the public transportation.

According to the technical scheme of the embodiment, because both the Doppler frequency shift and the wireless signal strength can reflect the door opening and closing event of the public transport vehicle, the door opening and closing event of the public transport vehicle can be identified through at least one of the first change characteristic of the Doppler frequency shift and the second change characteristic of the wireless signal strength, and therefore the arrival event is identified. It can be understood that the identification of the door opening and closing event is carried out through the Doppler frequency shift and the wireless signal strength, the identification blind areas of the Doppler frequency shift and the wireless signal strength can be compensated, the effect that 1+1 is greater than 2 can be achieved, and the accuracy of the identification of the arrival event is improved.

The following embodiments are described in terms of how to detect whether a public transportation vehicle maintains an open door state between a set of door open events and door close events based on any of the above embodiments.

Referring to fig. 4, fig. 4 is a flowchart of a refinement of step 330 provided by an embodiment. In one embodiment, as shown in fig. 4, step 330, detecting whether the public transportation vehicle maintains a door open state between a set of door open events and door close events includes steps 410 through 440.

And step 410, acquiring wireless network characteristics measured by the terminal when the public transportation means is between a group of door opening events and door closing events, wherein the wireless network characteristics comprise Doppler frequency shift and wireless signal strength.

Wherein the wireless network characteristics refer to characteristics of a wireless network. The wireless network characteristic of the embodiment is the wireless network characteristic measured by the terminal when the public transport means is between a set of door opening events and door closing events. The wireless network feature of the present embodiment is used to characterize the door state of the public transportation vehicle, in other words, it can be detected through the wireless network feature whether the public transportation vehicle maintains the door-open state between a set of door-open events and door-close events. The wireless network characteristics of the present embodiment include doppler shift and wireless signal strength.

And step 420, determining whether the Doppler frequency shift is within a preset frequency shift range and exceeds a sixth preset time.

The preset frequency shift range can be determined by measuring the Doppler frequency shift of the public transportation means in a static state. The sixth preset time may be determined according to an interval time for opening and closing the door. Typically, the sixth predetermined time is less than the interval between a set of door opening events and a set of door closing events. In this step, if the doppler frequency shift is within the preset frequency shift range and exceeds the sixth preset time, step 430 is executed.

And 430, determining whether the wireless signal strength of the same serving cell is within a preset strength range and exceeds a seventh preset time.

The preset intensity range can be determined by placing the terminal in a public transport means and measuring the wireless signal intensity when the public transport means is in a door opening state. The seventh preset time may be determined according to an interval time for opening and closing the door. Typically, the seventh predetermined time is less than the interval between a set of door opening and door closing events. In this step, if the wireless signal strength of the same serving cell is within the preset strength range and exceeds the seventh preset time, step 440 is executed.

In this step, the serving cell refers to a cell that can provide a network camping service. The step is to determine whether the public transport means keeps the door opening state or not according to the wireless signal intensity of the same service cell. It can be understood that, since the wireless signal strengths of different serving cells may be different, if the wireless signal strength may suddenly change with reference to the wireless signal strengths of different serving cells, the wireless signal strengths of different serving cells may not be within the preset strength range, and the detection result of the open-door state may be inaccurate. Whether the public transport means keeps the door opening state or not is determined through the wireless signal intensity of the same service cell, and the accuracy of door opening state detection can be improved. Wherein, the same serving cell may be a serving cell where the terminal resides. Specifically, if a sudden change of signal needs to be detected at a certain time, the wireless signal strength change of the serving cell where the terminal resides is detected according to the current time, but not other cells.

And step 440, determining that the public transport means keeps the door opening state.

In this embodiment, whether the doppler shift is within the preset shift range exceeds a sixth preset time, and

and if the wireless signal intensity of the same service cell is within a preset intensity range and exceeds seventh preset time, determining that the public transport means keeps the door-opening state.

It should be noted that step 420 and step 430 in the above embodiments may be interchanged with each other.

Further, the wireless network characteristic may include only one of doppler shift and wireless signal strength. When the wireless network characteristics include one of doppler shift and wireless signal strength, the condition for determining whether to keep the door-open state is as follows: and if the Doppler frequency shift is within a preset frequency shift range and exceeds a sixth preset time, determining that the public transportation means keeps the door-open state, or if the wireless signal intensity of the same serving cell is within a preset intensity range and exceeds a seventh preset time, determining that the public transportation means keeps the door-open state.

Referring to fig. 5, fig. 5 is a diagram illustrating the result of identifying an arrival event through wireless signal strength according to an embodiment. As shown in fig. 5, when a station arrival event occurs once, the public transportation means may generate a door opening event, keep the door opening state, and generate a door closing time, which are represented by wireless signal strength, that is, a series of processes in which the wireless signal strength changes from low to high within a third preset time, the wireless signal strength is within a preset strength range and exceeds a seventh preset time, and the wireless signal strength changes from high to low within a fifth preset time, and it may be considered that the station arrival event occurs once in the public transportation means.

The signal strength change is caused by the opening and closing of doors of public transport means, and is different from the slow signal change caused by the normal movement of electronic equipment, wherein the signal abrupt change is defined as the signal strength changing to the signal strength exceeding a certain preset threshold within a preset short time, for example, the signal changes from-110 dbm to-100 dbm after only 200 ms. The signal is confirmed to be mutated. After the train opens the door, the signal becomes strong, and when the wireless signal intensity is in the preset intensity range and exceeds the seventh preset time, the public transport means can be confirmed to be kept in the door opening state at the moment, and the false recognition caused by signal jitter is avoided.

The following embodiments are described with respect to how to identify the station information on the travel route of the public transportation by the arrival event on the basis of any of the above embodiments.

In one embodiment, identifying the station information on the travel route of the public transportation means through the arrival event includes:

acquiring an intermediate station between a starting station and a destination station of a user on a driving route of the public transport means; when the station number of the intermediate station is the same as the number of the arrival events, detecting whether a final door opening event occurs in the public transport means; and if the final door opening event occurs to the public transport means, determining that the public transport means arrives at the destination station.

Referring to fig. 6, fig. 6 is a third flowchart illustrating a method for identifying station information according to an embodiment. As shown in fig. 6, the method for identifying station information includes steps 610 to 660.

And step 610, acquiring the wireless network change characteristics measured by the terminal in the public transport means.

And step 620, identifying the arrival event of the public transport means according to the wireless network change characteristics.

And 630, acquiring an intermediate station between the starting station and the destination station of the user on the driving route of the public transport means.

Wherein the destination site refers to a site to which the user wishes to go. The destination station of the present embodiment is one of the stations on the traveling route of the public transportation. Optionally, the destination site may be input by a user on a visual interface, or the destination site may be predicted according to data, which is not limited herein. The determination of the starting site may be performed by a user through input on a visual interface, or may be performed by predicting the starting site according to data, which is not limited herein. It should be noted that the starting station may be a station when the user enters the public transportation means, or may be a first corresponding station when the identification method of the station information is triggered. For example, when a user enters a subway, the user forgets to turn on the identification function of the station information, and turns on the identification function of the station information after taking several stations, and then the station is identified as a starting station when the identification method of the station information is triggered. An intermediate site refers to a site between an originating site and a destination site. Illustratively, the stations on the driving route are sequentially a, B, C, D and E, and if the starting station is a and the destination station is E, the intermediate station includes B, C and D; if the originating site is B and the destination site is D, C is included in the intermediate sites. In this embodiment, the originating station does not participate in the identification process of the event of arrival.

It should be noted that the method for identifying the station information according to the embodiment may be triggered when the user is detected to enter the public transportation vehicle. There are many ways to identify the user entering the public transportation means, which may be based on location, or by means of user card swiping information, etc., and this is not limited herein.

And step 640, judging whether the station number of the intermediate station is the same as the frequency of the arrival event.

In this step, when the number of stations of the intermediate station is the same as the number of arrival events, step 650 is performed.

And step 650, detecting whether the public transport means has a final door opening event.

Wherein, the final door opening event refers to the last door opening event. It should be noted that, in this step, if the final door opening event occurs in the public transportation, step 660 is executed.

Step 660, determining that the public transportation means arrives at the destination station.

In this embodiment, if the number of stations at the intermediate station is the same as the number of arrival events and the final door opening event occurs in the public transportation, it can be confirmed that the public transportation has arrived at the destination station.

According to the technical scheme of the embodiment, whether the public transport reaches the destination station or not is detected through the station number of the intermediate station and the times of the arrival time, and when the station number of the intermediate station is the same as the times of the arrival events, whether the public transport reaches the destination station or not is determined.

The following embodiments are based on any of the above embodiments, and describe how to acquire an intermediate station.

In one possible embodiment, acquiring an intermediate station between a starting station and a destination station of a user on a travel route of the public transportation means includes:

receiving the starting station and the destination station input by the user; calling a station list, wherein the station list comprises a plurality of stations arranged according to the driving direction of the public transport means; and extracting a station between the starting station and the destination station from the station list as the intermediate station.

In this embodiment, the origination site and the destination site are input by a user, and specifically, the input may be input by the user through a visual interface of the electronic device, which is not limited herein. In the present embodiment, by the station list including a plurality of stations arranged in the traveling direction of the public transportation, a station between the start station and the destination station can be extracted from the list as an intermediate station.

In one embodiment, after said determining that the public transportation arrives at the destination site, comprising:

and prompting a user that the public transport means arrives at the destination station in response to a detection result that the public transport means arrives at the destination station.

In this embodiment, the manner of prompting the user includes, but is not limited to, voice prompting, prompting on a visual interface, and the like, which is not limited herein.

It is understood that the user is alerted when it is determined that the public transportation means has reached the destination station, so as to prevent the user from sitting and standing.

It should be noted that, in the above embodiments, a set of identification rules is used to identify whether a station arrival event occurs in a public transportation vehicle, and the following embodiments provide another possible implementation manner to identify whether a station arrival event occurs in a public transportation vehicle.

In one embodiment, identifying the arrival event of the public transportation vehicle based on the wireless network change characteristic comprises:

acquiring a reference change characteristic corresponding to each intermediate station, wherein the reference change characteristic is a change characteristic of each intermediate station measured in advance; identifying a nearest arrived stop of the public transportation vehicle; acquiring a reference change characteristic corresponding to a next station of the arrived stations; and if the wireless network change characteristic is matched with a reference change characteristic corresponding to the next station of the arrived stations, determining that the public transport means has the station arrival event once.

Referring to fig. 7, fig. 7 is a fourth flowchart illustrating a method for identifying station information according to an embodiment. As shown in fig. 7, the method for identifying site information in one embodiment includes steps 710 to 790.

And step 710, acquiring the wireless network change characteristics measured by the terminal in the public transport means.

The step may refer to the description of any of the above embodiments, which is not repeated herein.

And 720, identifying the nearest arrived station of the public transport means.

The arrived station refers to a station which has arrived in an intermediate station between an initial station and a destination station. The arrived station in this embodiment refers to the nearest arrived station.

In one possible embodiment, the nearest arrived station of the public transport vehicle is identified by calling a station list, wherein the station list comprises a plurality of stations arranged according to the driving direction of the public transport vehicle, the station list can be used for determining the specific station of the intermediate station, and the intermediate station is reached when each arrival event occurs, so that the nearest arrived station can be identified through the station list and the occurrence frequency of the arrival events.

Illustratively, the intermediate sites include a, B, and C, and if after the first arrival event is identified and before the second arrival event is identified, the most recently arrived site is a.

Step 730, obtaining a reference change characteristic corresponding to the next station of the arrived station, where the reference change characteristic is a change characteristic of each station measured in advance.

In this embodiment, the variation characteristic of each station is measured in advance, and the measured variation characteristic is used as the reference variation characteristic of the station.

And 740, detecting whether the wireless network change characteristic is matched with a reference change characteristic corresponding to the next station of the arrived station.

In this step, if the wireless network change characteristic matches the reference change characteristic corresponding to the station next to the arrived station, it is indicated that the public transportation has arrived at the station next to the nearest arrived station, and therefore step 750 is executed.

In one possible implementation, if the similarity between the wireless network change characteristic and the reference change characteristic exceeds a similarity threshold, the wireless network change characteristic may be considered to match the reference change characteristic.

Step 750, determining that the arrival event occurs once in the public transportation means.

In this step, if the wireless network change characteristic matches a reference change characteristic corresponding to a station next to the arrived station, it is determined that an arrival event occurs in the public transportation.

And step 760, acquiring an intermediate station between the starting station and the destination station of the user on the driving route of the public transport means.

Step 770, judging whether the station number of the intermediate station is the same as the number of the arrival events.

Step 780, detecting whether the public transport means has a final door opening event.

Step 790, determining that the public transportation means arrives at the destination station.

According to the technical scheme of the embodiment, the identification of the arrival event is determined through the comparison result of the measured wireless network change characteristic and the reference change characteristic of the station, and it can be understood that the door opening and closing conditions are not necessarily the same when different stations arrive, so that the change characteristic of each station is measured in advance as the reference change characteristic, the identification of the arrival event is performed through the reference change characteristic, and the identification accuracy of the arrival time can be improved.

In an embodiment, whether an arrival event identification error condition exists in two adjacent arrival events can be checked by determining two adjacent sites corresponding to the two adjacent arrival events and determining an average running time between the two adjacent sites, so as to compare the average running time between the two adjacent sites according to the interval time between the two adjacent arrival events with the average running time between the two adjacent sites.

It can be understood that when the common public transport means runs relatively on time, the average running time between two stations is relatively fixed, and the error is relatively small. In the process of predicting the door opening and closing of a starting station and a train set by a user, if a certain station does not reliably detect the door opening and closing event, the prediction is assisted according to the historical average running time of the predicted station and the next station, and the accuracy is improved.

In some exemplary cases, the public transportation vehicle has a temporary stop, and if the last door opening event is caused by the temporary stop, there may be a case that the destination station is mistakenly identified, that is, the destination station is not reached but is identified as the destination station, and therefore, it is necessary to avoid such a case.

In one embodiment, determining that the public transportation vehicle arrives at the destination site comprises:

acquiring a third interval time between a final door opening event and an adjacent door closing event before the final door opening event; acquiring the running time between the destination station and the station adjacent to the destination station; and if the difference value between the third interval time and the running time is less than a time difference value threshold, determining that the public transport means arrives at the destination station.

The time difference threshold may be set as needed, and is not limited herein. It can be understood that, in this embodiment, if a final door opening event occurs in the public transportation, whether the public transportation really reaches the destination station is verified according to the third interval time, so that a problem in an identification result of the arrival of the destination station due to temporary parking can be avoided, and the accuracy of detecting whether the public transportation arrives at the destination station is improved.

Referring to FIG. 8, FIG. 8 is a flowchart detailing step 210 in one embodiment. In one embodiment, as shown in fig. 8, step 210, obtaining wireless network variation characteristics measured by a terminal located in a public transportation means includes steps 810 to 820.

And step 810, detecting whether the public transportation means is in a running state.

In this step, it is detected whether the public transportation is in a traveling state.

In one possible embodiment, detecting whether the public transportation vehicle is in a driving state comprises:

acquiring the current Doppler frequency shift measured by the terminal; and if the duration that the current Doppler frequency shift is larger than the frequency shift threshold value exceeds a ninth preset time, determining that the public transport means is in a running state.

In the present embodiment, the current doppler shift refers to a doppler shift measured at the current time. The frequency shift threshold may be set as desired. The frequency shift threshold value can be determined according to the Doppler frequency shift in the driving process by measuring the Doppler frequency shift in the driving process of the public transportation means. Typically, the frequency shift threshold is less than the measured doppler shift during travel. In the present embodiment, if the duration in which the doppler shift is greater than the frequency domain threshold exceeds the ninth preset time, it is determined that the public transportation is in the traveling state.

And step 820, responding to the detection result that the public transport means is in the running state, and acquiring the wireless network change characteristics measured by the terminal in the public transport means.

In this step, when it is detected that the public transportation means is in a driving state, the wireless network change characteristics are acquired, and thus the arrival event is identified.

It can be understood that, in order to avoid missing the identification of the arrival event, the arrival event needs to be identified in real time through the wireless network change characteristic, but the identification of the arrival event through the wireless network change characteristic in real time inevitably results in an operation resource of the electronic device.

It should be noted that, considering the volatility measured by the terminal, if a certain proportion of the detection times all satisfy the condition, the public transportation means is considered to be in a driving state. And detecting for about 10 times in total, and if 9 times within 10 times are greater than the preset threshold, considering that the condition is met, and determining that the public transport means is in a running state.

In one embodiment, the public transportation means is divided into a plurality of candidate areas, and the method for identifying the arrival information further comprises the following steps:

when the arrival event of the public transport means is identified, acquiring radio frequency fingerprint information acquired by the terminal;

acquiring reference fingerprint information associated with each candidate area in the public transport means, wherein the reference fingerprint information is fingerprint information of each candidate area measured in advance;

identifying target reference fingerprint information matched with the radio frequency fingerprint information;

and taking the candidate area associated with the target reference fingerprint information as a target area of the terminal in the public transport means.

The radio frequency fingerprint information refers to the radio frequency information of the characterization position, the reference fingerprint information refers to the fingerprint information of each candidate area measured in advance, and the fingerprint information measured in advance is used as the reference fingerprint information of the candidate area. In an embodiment, the target reference fingerprint information matched with the radio frequency fingerprint information is identified from the reference fingerprint information respectively associated with the plurality of candidate areas, so that the candidate area associated with the target fingerprint information is used as the target area of the terminal in the public transportation vehicle.

For example, taking a public transportation vehicle as an example of a train, each car can be taken as a candidate area, and the identified target area corresponds to which car the user is located in.

According to the technical scheme of the embodiment, when the arrival event of the public transport means is identified, the specific position of the user can be identified according to the radio frequency fingerprint information collected by the terminal.

In one embodiment, the radio frequency fingerprint information includes at least one of first cell information of a current serving cell where the terminal resides and second cell information of a neighboring cell of the current serving cell.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
