Embodiments of the present application will be described below with reference to the accompanying drawings.
The embodiment of the application provides an electronic roll call method, as shown in fig. 1, the method includes: step S102 to step S106.
Step S102, obtaining current roll call data, wherein the current roll call data comprises roll call data of at least one train number, and the roll call data comprises train number information of the subway and carriage information of the subway.
In the embodiment of the application, if the roll call data includes roll call data of one train number, the obtained current roll call data belongs to a roll call result of the one train number, and if the roll call data includes roll call data of a plurality of train numbers, the obtained current roll call data belongs to roll call results of the plurality of train numbers.
And step S104, determining the personnel density information of each compartment in each train number based on the current roll call data.
For the embodiment of the present application, the information on the density of people in any car may include: the current number of people in any one compartment accounts for the maximum number of people in any one compartment, and can also be the current number of people in the compartment. In the embodiment of the application, the proportion of the maximum number of passengers in any compartment is preset.
And step S106, sending the personnel density information of each compartment in each train number to corresponding equipment so as to display the personnel density information on the corresponding equipment.
For the embodiment of the present application, the corresponding device in step S106 may be any device that needs to display the person density information, may be a terminal device, or may be a certain display device, which is described in detail in the following embodiments and is not described herein again.
According to the embodiment of the application, after the current roll call data is acquired, the personnel density information of each compartment in each bus number can be determined based on the current roll call data, the personnel density information of each compartment in each bus number is sent to the corresponding equipment and displayed, so that a user waiting for the bus can know the personnel density information in each compartment through the display content of the corresponding equipment, the user can conveniently and reasonably select the compartment needing to enter according to the personnel density information in different compartments, and the bad experience that the user cannot get on the bus smoothly due to the fact that the user blindly selects too many compartments in the early peak taking the bus is avoided.
Referring to step S102, the obtained train number information of the subway included in the current roll call data carries the name of the train number and the corresponding roll call result (e.g., the number of subway people per train number obtained by roll calling), and for example, the train number information of the subway is "XX train number" and includes 100 people. In addition, the name of each car and the corresponding roll call result (such as the number of people in each car obtained by roll call) are carried in the car information of the subway, the name of the car can be the serial number of the car, and the car information of the subway is as follows: the 1 st car of the "XX train number" subway contains 10 people, the 2 nd car of the "XX train number" subway contains 20 people, and the like. The embodiment of the application does not limit the specific content of the train number information and the carriage information of the subway.
In an embodiment of the present application, the density information of people in each car in each train may include a user congestion level, and when determining the density information of people in each car in each train based on the current roll call data in step S104, the congestion level corresponding to each car in each train may be determined based on the number of people in each car in each train. In the embodiment of the application, the congestion level corresponding to each carriage can be determined based on the proportion of the current number of people in each carriage to the maximum number of people in each carriage; of course, the congestion level corresponding to each car may be determined by the number of people currently corresponding to each car. In the embodiment of the present application, the correspondence between the ratio of the current number of people in each car to the maximum number of people in each car and the congestion level may be set in advance, or the correspondence between the number of people in each car and the congestion level may be set in advance.
Next, the congestion level corresponding to each car in one train is determined as an example. Firstly, the current number of people of each carriage in the current roll call data of the train number is respectively matched with different number of people intervals, and the number of people intervals to which each carriage belongs is obtained through matching. Then, according to the corresponding relation between the different people number sections and the corresponding crowding levels, the crowding levels respectively corresponding to the people number sections to which each carriage belongs are searched. Wherein, a region of people corresponds to a congestion level.
For example, a subway of one train number includes 1 car, 2 cars, and 3 cars, and the number of persons in each of the cars 1, 2, and 3 included in the current roll call data is: the current number of people in the carriage 1 is 21, the current number of people in the carriage 2 is 15, and the current number of people in the carriage 3 is 5. The preset different people number intervals comprise 0-10, 10-20, 20-30 and other people number intervals, the 0-10, 10-20 and 20-30 people number intervals respectively correspond to the congestion levels of 1 level, 2 levels and 3 levels, and the congestion degree is larger when the congestion level is larger. By matching the number of people in each compartment with the number of people in different compartments, it is found that the compartment 1 belongs to the 20-30 number of people compartment, the compartment 2 belongs to the 10-20 number of people compartment, and the compartment 3 belongs to the 0-10 number of people compartment. Further, it is determined that the congestion level of the car 1 is level 3, the congestion level of the car 2 is level 2, and the congestion level of the car 3 is level 1.
Therefore, according to the embodiment of the application, the congestion level of each carriage in the corresponding train number is determined according to the roll call data of each carriage in the train number, and the congestion level of each carriage is displayed on the corresponding equipment in the following process, so that a user can clearly know the congestion levels of different carriages.
In an alternative embodiment of the present application, a corresponding level identifier may be set for each congestion level, and the level identifier of the congestion level may be displayed at the corresponding device. For example, the level identifier corresponding to the congestion level of 1 is a green identifier, the level identifier corresponding to the congestion level of 12 is a yellow identifier, and the level identifier corresponding to the congestion level of 13 is an orange identifier. For another example, a level corresponding to a congestion level of 1 is denoted by "personal image id", a level corresponding to a congestion level of 12 is denoted by "two-person image id", and a level corresponding to a congestion level of 13 is denoted by "three-person image id". The embodiment of the present application does not specifically limit the type and color of the level identifier. According to the embodiment of the application, the personnel density of the carriage is reflected by the identification of the congestion level of the carriage, so that the personnel density condition of the carriage can be more obvious for a user, and the user can more intuitively know the personnel density condition of each carriage.
In the embodiment of the present application, only the congestion level or the level identifier may be displayed on the corresponding device, or the congestion level and the corresponding level identifier may be displayed at the same time, which is not specifically limited in the embodiment of the present application.
In an embodiment of the present application, the device for displaying the people density information of each car may be a display device disposed at the platform position, and one car position corresponds to one display device. The display device can be a large display screen or other display devices. In the step S106, the density information of the persons in each car in each train can be transmitted to the display devices corresponding to the cars, wherein the display devices are the display devices at the stop positions of the cars in each train. For example, a subway of a train stops at the station 2, and the information on the density of people in each car in the train is sent to the display device at the stop position of each car in the station 2. Therefore, by adopting the embodiment of the application, before the subway arrives at the station, the waiting user can know the personnel density information of each carriage from the display equipment, so that the user can reasonably select the carriage position with lower personnel density for getting on the train.
Of course, in the embodiment of the present application, the density information of the people in each car in one train number may also be sent to a designated display device in the next stop of the train number, the density information of the people in each car may be displayed in a centralized manner by the display device, and the display device may be disposed at a position just entering the waiting platform, so that when a user enters the waiting platform, the user may directly select a corresponding car position according to the displayed information to wait.
In another embodiment of the present application, if a people density request message is received, the device that presents people density information for each car may also be the sender device of the request message. The sender device may be a terminal device, such as a smart phone, a smart watch, or the like. Therefore, this embodiment may also send the person density information to be requested to the sender device of the request message when performing step S106. In the embodiment of the application, the train number information to be requested is determined based on the personnel density request message.
In this embodiment, the received staff density request message may include the train number information to be requested, and therefore, the train number information to be requested may be determined according to the staff density request message. The train number information to be requested may include train number information of one train number or a plurality of train numbers, and is not particularly limited herein.
In an optional embodiment, the density information of the people to be requested may include density information of people corresponding to the train number information to be requested, and therefore, the embodiment of the application may send the determined density information of the people of the train number to be requested to the sender device of the request message, that is, the density information of the people of all the people included in the train number to be requested is sent to the corresponding sender device, so that the user may know the density information of the people included in the requested train number through the sender device.
In another optional embodiment, the density information of the persons to be requested may further include density information of the persons corresponding to each car in the train number information to be requested. Therefore, the person density information corresponding to each compartment in the determined train number information to be requested can be sent to the corresponding sender equipment, namely the person density information of each compartment in the train number to be requested is sent to the corresponding sender equipment, so that a user can specifically know the person density information of each compartment requesting the train number through the sender equipment.
In this embodiment of the application, the staff density request message may carry the starting station information and the ending station information, and therefore, the mode of determining the train number information to be requested may be to determine the train number information to be requested based on the starting station information and the ending station information. The station information of this embodiment may be a subway station name, or may be station information such as address information. If the starting site information and the ending site information carried in the personnel density request message are address information, the corresponding starting site name and the corresponding ending site name can be analyzed according to the address information.
For example, the received person density request message carries the starting site name "site a" and the ending site name "site C", so that the information of the train number driving from "site a" to "site C" can be determined. And then the personnel density information of each carriage in each train number from the station A to the station C can be sent to the sender device of the request message. Therefore, the user can conveniently know the personnel density information of each carriage in the subway of each train number in the subway station to be taken in advance (such as before entering the subway station).
Of course, if the staff density request message does not carry the stop station information, the direction of the user taking the subway cannot be determined, so a prompt message prompting the user to input the stop station information can be sent to the request message sender equipment, so as to determine the direction of the user taking the subway according to the stop station information. By prompting the user to input the stop station information, the direction of taking the subway can be accurately analyzed for the user, and the information of the number of cars to be requested can be accurately determined.
If the staff density request message does not carry the start site information, the start site information that the user of the sender device may possibly take the subway can be determined according to the Positioning information of the sender device and the stop site information by acquiring the GPS (Global Positioning System) Positioning information of the sender device. For example, in the direction from the position of the sender device to the end station, the subway station closest to the positioning information of the sender device is used as the start station, so as to obtain the start station information. Therefore, even if the personnel density request message does not carry the initial station information, the initial station information that the user is about to take the subway can be determined, and the train number information to be requested is determined based on the initial station information and the terminal station information.
The train number information to be requested, which is determined based on the starting station information and the ending station information in the embodiment of the application, may include train number information of a plurality of train numbers, and in order to further determine the train number of the subway which the user may take more accurately, the train number information to be requested may be determined by combining the time when the user arrives at the starting station. I.e. if the user arrives at the originating site at 9:00, then 9:00 or 9:00 the number of cars that first arrive at the origin station is taken as the information of the number of cars to be requested. In the embodiment of the application, the personnel density request message determined for the last time before the train number to be requested reaches the starting station is sent to the sender device.
First, the location information where the sender device was when sending the person density request message is determined. Alternatively, the embodiment may obtain the location information of the sender device by acquiring GPS positioning information of the sender device when receiving the person density request message. Or the user can input the current position information of the user and carry the current position information to the personnel density request message, namely, the position information carried by the personnel density request message is directly obtained from the personnel density request message.
Then, the train number information taken when the user arrives at the starting station is determined based on the position information, the starting station information and the ending station information when the sender device sends the personnel density request message, and the train number information taken when the user arrives at the starting station is used as the train number information to be requested.
In this embodiment, the process of determining the train number information taken when the user arrives at the start site may be that, first, the time when the user to which the sender device belongs arrives at the start site is calculated based on the position information when the sender device sends the density of people request message, the start site information, and the speed information of the user to which the sender device belongs. Then, based on the time when the user arrives at the starting station, the number of subway cars which the user may take when arriving at the starting station is determined. The speed information of the user may be input by the user and carried in the personnel density request message, or may be a preset average speed of a general user, which is not specifically limited in this embodiment of the application.
Further, in the process of executing step S106, when the person density information corresponding to each car in the train number information to be requested is acquired, the acquired person density information may be sent to the sender device of the request message.
For example, the start station name obtained from the person density request message transmitted from the terminal device of the user 1 is "a station", the end station name is "C station", and the terminal device location information is the D location. The preset average speed of the normal user is 80 m/min. Then, the time for user 1 to reach "site a" can be calculated according to the distance between the position of "site a" and position D and the average speed, for example, the time for user 1 to reach "site a" is calculated to be 9: 00. Then, subway train number information which arrives at the station A and drives to the station C at a ratio of 9:00 is analyzed according to a preset subway schedule, and the determined subway train number information is used as train number information to be requested by the user 1. Further, when acquiring the person density information corresponding to each compartment in the train number information to be requested by the user 1, the acquired person density information is sent to the terminal device of the user 1. In this example, the person density information corresponding to each car determined before the train number information to be requested arrives at the station a is sent to the terminal device of the user 1, for example, if the last station before the station arrives at the station a is the station M, the person density information corresponding to each car determined between the station M and the station a is sent to the terminal device of the user 1.
In the embodiment of the application, when the subway runs between any two adjacent stations, electronic roll calling is carried out on users in the corresponding subway. Specifically, an electronic roll call instruction is triggered when the subway runs between any two adjacent parking positions (namely two adjacent stations), and current roll call data of the subway are obtained in an electronic roll call mode after the electronic roll call instruction is received. In this embodiment, the number of subways which are usually in the process of traveling corresponds to the number of train numbers in the acquired roll call data.
For example, referring to fig. 2, for a subway of a certain train number, when the subway travels between a station 1 and a station 2, an electronic roll call instruction is triggered, current roll call data is acquired in an electronic roll call (that is, the electronic roll call 1 in fig. 2), and the density information of people in each car determined based on the current roll call data is sent to a device corresponding to a stop position of each car in the station 2. After the subway arrives at a station, passengers get on or off the subway, and the number of the passengers in each carriage of the subway can be changed at the moment. When the subway is started to run again, namely the electronic roll call instruction is triggered again in the process of running from the station 2 to the station 3, the current roll call data is obtained through the electronic roll call (namely the electronic roll call 2 in the figure 2), and the personnel density information of each carriage determined based on the current roll call data is sent to the equipment corresponding to the stop position of each carriage in the station 3. That is, each time the subway station triggers an electronic roll call between two adjacent stations.
According to the embodiment of the application, electronic roll calling is carried out when the subway runs between two adjacent stations, the personnel density information of each carriage in each train number is determined based on the obtained electronic roll calling result (namely roll calling data), the obtained electronic roll calling data are more stable and accurate, and therefore the accuracy and the real-time performance of the determined carriage personnel density information are higher. Moreover, the determined personnel density information of each carriage can be displayed on the corresponding equipment which is about to arrive before the subway arrives at the station, namely the current personnel density information of each carriage is displayed on the corresponding equipment before the subway arrives at the station, so that a user can reasonably select the position of the carriage which is about to get on the train in advance.
The electronic roll call mode of the embodiment of the application can adopt a Bluetooth electronic roll call mode, and the Bluetooth electronic roll call mode can be based on a Bluetooth positioning system to carry out roll call. The Bluetooth positioning system comprises a Bluetooth base station positioned in a subway carriage, a resolving server, a positioning server for acquiring positioning information of the terminal equipment and the like.
In this embodiment, the terminal device of the user starts the bluetooth positioning function and then transmits bluetooth information to the bluetooth base station. The Bluetooth base station receives Bluetooth signals sent by the terminal equipment, and after receiving the Bluetooth signals sent by the terminal equipment, the Bluetooth base station determines course angle and pitch angle information between the base station and the terminal and sends the angle information to the resolving server. And the resolving server calculates the positioning information of the terminal equipment according to the angle information and sends the positioning information of the terminal equipment to the positioning server. The positioning server has an electronic roll call function, and an electronic roll call instruction can be triggered by calling an interface of the positioning server in the subway running process, for example, the interface can adopt an Http (hypertext Transfer Protocol) interface and the like. And then the positioning server executes the electronic roll call task and generates roll call data. The positioning server can plan roll calling areas for subway train numbers and name the roll calling areas according to the train number names and the carriage names, so that the obtained roll calling data comprise the train number names and the carriage names of the subways.
In this embodiment, the terminal device of the user may adopt a smart phone, a smart watch, and the like, which is not specifically limited herein.
Optionally, the resolver server in the bluetooth positioning system according to the embodiment of the present application may calculate the positioning information of the terminal device in an Angle-of-Arrival (AOA) manner, or may calculate the positioning information of the terminal device in a Time-of-Arrival (TOA) manner or an Angle-of-departure (AOD) manner, and the embodiment of the present application does not specifically limit the manner of calculating the positioning information of the terminal device. Of course, in the embodiment of the present application, UWB (Ultra Wide Band) may also be used to position the terminal device, and the positioning manner of the terminal device is not specifically limited in the embodiment of the present application.
In an embodiment of the application, for a route recommendation request message triggered by a user, a transfer route may also be recommended for the corresponding user. Referring to fig. 3, the process of recommending a transfer route for a user includes steps S302 to S308.
Step S302, a route recommendation request message triggered by a user is obtained, wherein the route recommendation request message carries starting site information and ending site information.
The station information of this embodiment may be a subway station name, or may be information such as address information. If the starting site information and the ending site information carried in the personnel density request message are address information, the corresponding starting site name and the corresponding ending site name can be analyzed according to the address information.
Step S304, determining a transfer line between the starting station and the ending station based on the starting station information and the ending station information, wherein the transfer line comprises the number of subway cars included between the starting station and the ending station.
In this embodiment, the transfer line between the determined starting station and the terminating station may be one transfer line or a plurality of transfer lines. Also, the transfer line between the starting station and the ending station may be determined based on a preset subway line map when determining the transfer line between the starting station and the ending station.
Step S306, determining a transfer line to be recommended based on the current personnel density information of each subway train number in the subway train numbers contained between the starting station and the ending station.
Step S308, the transfer line to be recommended is sent to the sending end of the route recommendation request message.
By adopting the method and the device, more reasonable transfer lines can be recommended to the user according to the line recommendation request message of the user, if the transfer lines with lower recommended personnel density are adopted, the riding experience of the user can be improved, and the personnel pressure of subway lines with higher personnel density can be effectively relieved.
In this embodiment, when determining a transfer route to be recommended, if it is determined in step S304 that one transfer route is included between the originating station and the terminating station, the transfer route may be directly transmitted to the transmitting end of the request message.
If it is determined in step S304 that a plurality of transfer lines are included between the starting station and the ending station, and if it is determined in step S306 that a transfer line to be recommended is included, a transfer line having a relatively low current person density of the number of subway cars included between the starting station and the ending station may be determined as the transfer line to be recommended.
For example, the person density information includes a user congestion level, and a transfer line with a smaller user congestion level of a subway train included between the starting station and the terminating station is determined as a transfer line to be recommended. In a specific embodiment, it is determined that the transfer route between the starting station "a station" and the ending station "C station" includes two transfer routes, the first transfer route includes two subway trains, the user congestion levels of the two subway trains are respectively 1 level and 2 levels, the second transfer route includes three subway trains, and the user congestion levels of the three subway trains are respectively 2 levels, 2 levels and 3 levels, and then the second transfer route can be determined as the transfer route to be recommended. Of course, the transfer route to be recommended may also be determined among the plurality of transfer routes according to other rules, which are not specifically limited herein. In an example, the congestion level is from high to low, indicating increasing congestion.
In an alternative embodiment, the transfer line to be recommended is determined by considering other factors such as the people flow density of the transfer line. After determining that a plurality of transfer lines are included between the starting station and the ending station in step S304, for each transfer line, the people flow density of the corresponding transfer line is calculated by dividing the sum of the current number of people of all train number subways included in the transfer line by the sum of the number of carriages of all train number subways in the transfer line. Therefore, the transfer line to be recommended can be determined according to two factors, namely current personnel density information of each subway train number in the transfer line and people stream density of the transfer line, the transfer line recommended to the sending end of the line recommendation request message by adopting the method is relatively more comprehensive in consideration of factors, and the transfer line can be recommended to a corresponding user more reasonably. Of course, the transfer route to be recommended may also be determined in combination with other factors (such as the number of transfers, the distance of the number of transfer cars, etc.), and is not particularly limited herein.
In this embodiment of the application, when step S308 is executed to send the transfer route to be recommended to the sending end of the route recommendation request message, the person density information of each car in each train number subway included in the transfer route to be recommended may also be sent to the sending end of the route recommendation request message, so that the user can clearly know the person density information of each car in each train number subway in the recommended route, and the user can conveniently and reasonably select a car to enter according to the person density information in different cars.
In an embodiment of the application, the riding information can be recommended for the user based on historical people density information corresponding to each train number and/or historical people density information of each compartment in each train number.
First, first historical information is acquired, wherein the first historical information comprises at least one item of information, such as historical personnel density information corresponding to each train number and historical personnel density information corresponding to each compartment in each train number. In this embodiment, the historical person density information corresponding to each train number is, that is, the person density information of all the persons included in each train number. The historical people density information corresponding to each compartment in each train number, namely the historical people density information is specific to each compartment and is the historical people density information of each compartment in each train number.
Then, the riding information is recommended for each user based on the first history information. The riding information comprises at least one item of riding time information, riding route information, riding compartment information and the like.
The riding time information may include information such as riding time periods and riding time points, the riding route information may include information such as transfer routes of riding, and the riding car information may include specific car numbers and car position information. The method for recommending the riding information for each user may be to send the recommended riding information to terminal devices of each user, or to send the recommended riding information to display devices installed at designated positions of the subway station for displaying, and of course, other recommending methods may also be adopted.
In this embodiment, if the acquired first historical information includes historical people density information corresponding to each train number, at least one of reasonable riding time information and riding route information may be recommended to each user according to the historical people density information of each train number. For example, when the riding time information is recommended for each user, a riding time period with lower historical passenger density can be recommended to the user according to the historical passenger density information of each train number in different time periods. For another example, when the riding route information is recommended for each user, a riding route with a lower historical person density (e.g., a transfer route with a lower historical person density) may be recommended to the user.
In this embodiment, if the acquired first historical information at least includes historical people density information corresponding to each car in each train number, in addition to recommending at least one of reasonable riding time information and riding route information for each user, the first historical information may also recommend the car information for each user. For example, a car with a smaller historical person density may be recommended to the user based on the historical person density information for each car in each train. Assuming that the historical person densities of the first car and the last car are small according to the historical person density information of each car in each train, the car information of the first car and the last car can be recommended to the user.
Therefore, according to the embodiment of the application, big data analysis can be performed according to historical personnel density information of each carriage in the subway train number, more reasonable riding time, riding routes, riding carriages and other information can be analyzed for a user and recommended to the user, the user can conveniently and independently select riding time, riding routes, riding carriages and the like suitable for the user before riding, and riding experience of the user is improved.
In an embodiment of the application, the riding information can be recommended for different users in a targeted manner based on the historical riding information of different users and the first historical information of the above embodiment.
First, before the riding information is recommended for each user based on the first historical information, second historical information is obtained, and the second historical information is history request messages sent by each user and/or trigger time of each history request message. In this embodiment, the history request message carries the starting site information and the ending site information. And, the history request message may include at least one of a history personnel density request message and a history route recommendation request message.
Then, based on the second historical information, historical riding information of each user is determined. In this embodiment, the historical ride information may include at least one of historical ride time information, ride route information, ride compartment information, and the like.
Further, the riding information is recommended for each user based on the second history information and the first history information of the above embodiment.
The history personnel density request message and the history line recommendation request message of the embodiment of the application can be sent by user terminal equipment, and the content of the received message can be recorded when the personnel density request message or the line recommendation request message sent by the terminal equipment is received before the embodiment of the application, so that the recorded request message can be used as the history request message, and the recorded message content is associated with the terminal equipment identification of the corresponding user.
Therefore, historical riding information of the user corresponding to the corresponding terminal identifier can be determined according to the recorded message content (namely, the second historical information) associated with different terminal device identifiers, and the riding information is recommended for each user based on the second historical information and the first historical information.
For example, by analyzing the plurality of pieces of history message content (i.e., the second history information) associated with the terminal device identifier a of the user 1, it is derived that the user 1 typically triggers the staff density request message within the time period of 8:00 to 8:30 in the morning, and the user 1 includes the starting site name "site a" and the terminating site name "site B" in the history staff density request message many times. Therefore, it can be determined that the historical riding information of the user 1 contains the content of riding the subway from the station A to the station B within the time period of 8:00-8: 30. Furthermore, specific riding time with low historical passenger density in a time period from 8:00 to 9:00 of the train number included in the line from the station A to the station B in the first historical information can be obtained, and if the historical passenger density from the station A to the station B is relatively low, the user 1 can be recommended to get on from the station A at 8:50 to 9: 00.
Of course, if it is found by analyzing the second history information of the user 1 that the user 1 often triggers the historical route recommendation request message within the time period of 8:00 to 8:30 earlier, and the historical route recommendation request message contains the starting site name "site a" and the ending site name "site B" many times, the transfer route with the lower density of the historical personnel included in the route from "site a" to "site B" in the first history information within the time period of 8:00 to 9:00 can be obtained and recommended to the user 1.
Therefore, according to the embodiment of the application, historical passenger density information of each carriage in each train number can be combined, riding information which accords with riding habits of different users is purposefully recommended for the different users according to the historical riding habits of the different users, and recommendation of personalized riding information of the different users is achieved, so that the users can conveniently ride in a staggered riding peak period, and a relatively uncongested riding route is selected for riding.
In an embodiment of the application, when a user is in danger in a dense place of people stream, if the user is invaded in a subway carriage, the user can trigger an alarm, and the embodiment of the application can timely take corresponding measures to help the user aiming at the alarm triggered by the user.
Specifically, when an alarm message triggered by an alarm user is received, terminal equipment matched with the position information in preset terminal equipment is determined based on the position information carried in the alarm message, and then the alarm message carrying the position information is sent to the matched terminal equipment.
In the embodiment of the application, the preset terminal equipment can be terminal equipment of subway managers. According to the embodiment of the application, the position information of the warning user is sent to the terminal equipment of the subway manager, so that the accuracy and efficiency of taking a rescue for the user can be improved, and the riding safety of the user is further improved.
In an optional embodiment, the position information carried by the warning message may include specific train number information and carriage information, so that the train number and the carriage position where the warning user is located can be directly and accurately determined according to the position information in the warning message. The position information carried by the warning message can also comprise coordinate position information of a user when the warning message is sent, the range of the subway line taken by the user can be analyzed according to the coordinate position information, and the train number and the carriage position of the warning user can be estimated by combining the time for sending the warning message, the running time of each train number in the corresponding subway line and other information.
In an optional embodiment, the manner of determining the preset terminal device, which is matched with the position information of the alert user, in the preset terminal devices may be to match a terminal device that is closer to the position information of the alert user from the preset terminal devices, for example, the preset terminal device in the car where the alert user is located may be matched, or the preset terminal device in a car adjacent to the car where the alert user is located may be matched, which is not specifically limited in this embodiment of the present application. By sending the warning message carrying the position information to the terminal equipment with a short distance, subway workers to which the terminal equipment belongs can provide help for warning users in time, and therefore the users can be helped in the fastest time.
In combination with the above embodiment, in an embodiment of the present application, when an alarm message triggered by an alarm user is received, an acquisition device matched with the position information may be determined based on the position information carried in the alarm message, and multimedia information acquired by the acquisition device is transmitted to a matched terminal device.
In the embodiment of the application, the preset terminal equipment can be terminal equipment of subway managers. According to the embodiment of the application, the multimedia information corresponding to the warning user is transmitted to the terminal equipment of the subway management personnel, so that the subway management personnel can conveniently know the dangerous process and surrounding environment of the warning user in time, reasonable and targeted help is provided for the user, and the accuracy and efficiency of rescuing the user are further improved.
The acquisition equipment in the embodiment of the application can be image acquisition equipment, such as monitoring equipment and the like, and can also be audio acquisition equipment, and the type of the acquisition equipment is not particularly limited in the embodiment of the application. The preset terminal device of the embodiment can be a terminal device of a subway manager, and for convenience of subsequent description, the matched terminal device can be defined as a terminal device of a target manager.
Further, in the embodiment of the present application, a matching relationship between the acquisition device and the installation location is preset, and in the received alarm information, the acquisition device matched with the position information carried in the alarm information may be determined based on the position information carried in the alarm information and the preset matching relationship between the acquisition device and the installation location, so that the multimedia information acquired by the matched acquisition device before and after the occurrence of the alarm information may be sent to the matched terminal device, and the matched terminal device may also call the matched acquisition device to acquire the multimedia information acquired by the acquisition device in real time. In addition, if a plurality of acquisition devices exist in the preset range, the acquisition device closest to the position of the warning user can be further determined.
In the embodiment of the present application, the modes of transmitting the multimedia information collected by the collection device to the matched terminal device include the following three modes.
And in the first mode, after the alarm message is received and the acquisition equipment matched with the position information of the alarm user is determined, the alarm message carrying the position information and the multimedia information acquired by the acquisition equipment in real time are transmitted to the target manager terminal equipment. The warning message and the multimedia information are transmitted to the terminal equipment of the target management personnel, so that the target management personnel can conveniently know the position information of the warning user and the corresponding multimedia information at the same time, and the dangerous condition of the warning user can be analyzed in time according to the two information so as to take reasonable emergency measures.
And secondly, after the alarm message is received and the acquisition equipment matched with the position information of the alarm user is determined, the alarm message carrying the position information can be sent to the target management personnel terminal equipment. And then transmitting the multimedia information acquired by the acquisition equipment in real time to the target manager terminal equipment. By separately transmitting the warning message and the multimedia information, the condition that the multimedia information possibly occupies a large memory to influence the transmission efficiency of the warning message can be avoided, and the problem that the target management personnel cannot acquire the position information of the warning user in time is avoided.
And thirdly, after the alarm message is received and the acquisition equipment matched with the position information of the alarm user is determined, the alarm message carrying the position information can be sent to the target manager terminal equipment. And then, when a multimedia information acquisition request sent by the target manager terminal equipment is received, transmitting the multimedia information corresponding to the alarm user to the target manager terminal equipment. Of course, other administrator terminal devices may also obtain the multimedia information corresponding to the warning user by sending a request.
The method can be suitable for the condition that the target management personnel is very close to the warning user, for example, after the terminal equipment of the target management personnel receives the warning message carrying the position information, the warning user is found to be positioned in the same carriage with the terminal equipment, the target management personnel can conveniently know the condition of the warning user on site, at the moment, the multimedia information corresponding to the warning user can be obtained without immediately, the multimedia information corresponding to the warning user is obtained after the condition is preliminarily known, and the efficiency of providing help for the warning user and processing the problem is improved for the target management personnel.
Of course, the manner of transmitting the multimedia information acquired by the acquisition device to the matched terminal device may also include other manners, which is not specifically limited in this application embodiment.
