[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the related technology, the arrival of a train at a platform or the departure of a train from a platform triggers a departure event. After receiving the train arrival and departure event, the PIS and PA calculation modules trigger the subsequent platform calculation logic, query the train number information that is scheduled to pass through this platform on the same day after the current time of this platform, and query the candidate train information that has not passed through the current platform. Insert the candidate train information that has not passed through this platform before the train number information that is scheduled to pass through this platform, and determine whether the current trigger to departure event is in the updated train number information list. If it is in this list, update the train number list according to the current trigger to departure train information. If it is not in this list, insert it to the first place in the train number list. The PISPA calculation module sends the first three pieces of information to the corresponding PIS and PA interfaces. After receiving the data, the PIS system and PA system display and broadcast the information.

[0044] During this process, if the train arrives and leaves the station on time according to the planned timetable information, the PISPA calculation module can accurately and timely display the train's arrival, departure and expected arrival information, and passengers will have a better experience.

[0045] If a train stops in a section or does not run at the planned speed, resulting in an early or late train, but the subsequent platform still processes the PIS and PA information according to the expected arrival information of the train leaving the previous platform, there will be a certain deviation. That is, the accuracy of the expected arrival information of the subsequent station calculated by the arrival and departure events of the train is not high, resulting in problems such as inaccurate PIS information and untimely PA broadcasts, which brings a bad experience to passengers.

[0046] Based on the above considerations, in order to improve the accuracy of PIS and PA information processing, thereby improving the passenger experience, the inventive concept of the present invention is: obtaining the position information and train operation plan of the train to be processed, the position information is determined based on the positioning device installed on the train to be processed; based on the position information and the train operation plan, screening out candidate trains corresponding to the target platform from the trains to be processed; based on the position information of the candidate trains and the position information of the target platform, providing information prompts and / or information broadcasts to the candidate trains.

[0047] In order to solve the problem of low accuracy in calculating the expected arrival information of subsequent stations through the arrival and departure events of trains, the location information of the train is obtained through the positioning equipment installed on the train, making the PIS and PA information processing more accurate and intelligent, which can significantly improve the accuracy of PIS and PA information processing, reduce errors, and thus effectively improve the passenger experience.

[0048] Based on the above-mentioned inventive concept, the present invention provides a train information prompt method, device, electronic device and storage medium, which are applied to PIS and PA information prompt scenarios in train operation control to improve the accuracy of PIS and PA information prompts.

[0049] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1 It is one of the flow charts of the train information prompting method provided by the present invention. The executor of each step in the method can be a train information prompting device, which can be implemented by software and / or hardware. The device can be integrated in an electronic device. The electronic device can be a terminal device (such as a smart phone, a personal computer, etc.), or a server (such as a local server or a cloud server, or a server cluster, etc.), or a processor, or a chip, etc.

[0050] In the embodiment of the present invention, the train information prompting device is taken as a central processing server as an example. Figure 1 As shown, the method may include the following steps:

[0051] Step 110, obtaining the location information and train operation plan of the train to be processed, wherein the location information is determined based on the positioning device installed on the train to be processed.

[0052] Specifically, the train to be processed may be any train running or parked on the line, for example, a light rail vehicle running on Line 2, or a subway vehicle running on Line 5, and the embodiment of the present invention does not specifically limit this.

[0053] A positioning device may be installed on the train to be processed to obtain the location information of the train. The positioning device may be based on the Global Positioning System (GPS), or based on the Beidou satellite navigation system, or may be based on a dual-mode positioning system based on both GPS and Beidou, which is not specifically limited in the embodiment of the present invention.

[0054] The location information here can be acquired in real time or periodically at a preset time interval. The preset time interval can be, for example, 30 seconds, 60 seconds, etc., and can be flexibly set according to needs.

[0055] The positioning device is connected to the central processing server for communication. The positioning device uploads the position information of the train to be processed to the central processing server in real time so that the central processing server can obtain the position information.

[0056] The train operation plan can represent the train operation plan, for example, it may include the running route of each train number, the stop platforms, and the stop time and stop duration at each platform.

[0057] Considering the problem of GPS signal drift leading to inaccurate positioning, in a preferred embodiment, the positioning equipment installed on the train to be processed is based on the Beidou satellite navigation system. By installing Beidou satellite navigation receivers and data transmitters on urban rail vehicles, the vehicle's location information can be automatically forwarded to the central processing server within a few seconds.

[0058] Step 120 , based on the position information and the train operation plan, select candidate trains corresponding to the target platform from the trains to be processed, where the candidate trains are trains that are planned to pass but have not yet passed the target platform.

[0059] Specifically, after obtaining the location information of the train and the train operation plan, the candidate train corresponding to the target platform can be determined for the target platform.

[0060] The target platform may be any platform on the train running line, and the number of the target platforms may be one or more, which is not specifically limited in the embodiment of the present invention.

[0061] The candidate train corresponding to the target platform refers to a train that is planned to pass through the target platform but has not yet passed through the target platform, and can be called a candidate train.

[0062] For example, for the target platform A, according to the train operation plan, there are 10 trains planned to pass through platform A, and 4 trains have passed. Therefore, there are 6 candidate trains corresponding to the target platform, and the specific train numbers of the 6 trains can be obtained by querying the train operation plan, so the 6 trains can be determined as candidate trains.

[0063] The train operation plan includes the operation route and time of each train, based on which the trains planned to pass the target platform can be obtained. On this basis, according to the position information of the trains planned to pass the target platform, it is determined whether the train has passed the target platform, thereby screening out the trains that are planned to pass but have not passed the target platform, namely the candidate trains.

[0064] It is understandable that the candidate trains screened from the trains to be processed are also online trains running or stopping on the line.

[0065] Step 130 , based on the position information of the candidate train and the position information of the target platform, provide information prompts on the position relationship between the candidate train and the target platform.

[0066] Specifically, the positional relationship between the candidate train and the target platform may include at least one of the number of stations from the train to the target platform, the time required for the train to reach the target platform, and the distance between the train and the target platform. The information prompt here may be a prompt of the positional relationship between the candidate train and the target platform. The prompt method may include information display based on the PIS system and / or information broadcast based on the PA system.

[0067] Information display based on the PIS system can be displayed through display terminals installed in station halls, platforms, entrances and exits, and trains, allowing passengers to understand train operation information in a timely and accurate manner. As a guidance system that provides information services to passengers, the passenger information system PIS plays a key role in the service quality and operation level of urban rail transit.

[0068] The information displayed based on the PIS system can specifically be a train arrival information prompt. For example, the information is displayed on the display terminal of the train, and the display content may be "This train will arrive at Station A in 5 minutes" to remind passengers on the train; for example, the information is displayed on the display terminal of the target platform, and the display content may be "Train No. X will arrive at this station in 5 minutes" to remind passengers waiting for the train on the platform.

[0069] The information broadcast based on the PA system can specifically broadcast the train's entry, arrival and departure information, providing passengers with more convenient information about the train's entry and exit. The information broadcast can be based on the train broadcast system to notify passengers on the train. The broadcast content can be, for example, "This train has arrived at station A. Passengers who need to get off, please get off in turn." The information broadcast can also be based on the station broadcast system to notify passengers waiting for the train on the platform. The broadcast content can be, for example, "Train No. X has arrived at this station. Passengers who need to get on, please get on in turn."

[0070] Since the position information of the candidate train is obtained through positioning equipment, it has higher accuracy and reliability, and the position information of the target platform is usually fixed. Therefore, based on the candidate train, the position relationship between the candidate train and the target platform can be prompted according to the position information of the candidate train and the target platform. The prompted position relationship is more accurate and reliable.

[0071] The method provided by the embodiment of the present invention obtains the position information of the train to be processed through the positioning device installed on the train, and then screens out the candidate train corresponding to the target platform from the train to be processed, and then based on the position information of the candidate train and the position information of the target platform, provides information prompts on the position relationship between the candidate train and the target platform, which can significantly improve the information processing accuracy of PIS and PA, reduce errors, and thus effectively improve the passenger experience.

[0072] In some embodiments, based on the location information of the candidate train and the location information of the target platform, information about the location relationship between the candidate train and the target platform is provided, that is, step 130 specifically includes:

[0073] Step 131, obtaining the running speed of the candidate train;

[0074] Step 132, determining the arrival time of the candidate train at the target platform based on the position information of the candidate train, the position information of the target platform, the travel speed, and the train stop time in the train operation plan;

[0075] Step 133: Based on the arrival time, information about the position relationship between the candidate train and the target platform is displayed.

[0076] Specifically, passengers usually do not have an intuitive experience of distance and number of stations. In order to further improve the passenger experience, the arrival time of the candidate train at the target platform can be displayed in the information prompt.

[0077] In order to obtain the arrival time of the candidate train at the target platform, the running speed of the candidate train may be first obtained. The running speed here may be the average speed over a period of time, and the average speed may be calculated based on the running distance and running time over a period of time, for example, the running distance is divided by the running time to obtain the average speed. The running speed may also be obtained by measuring the speed through a speed sensor device of the vehicle control system, which is not specifically limited in the embodiment of the present invention.

[0078] On the basis of obtaining the travel speed, the arrival time of the candidate train at the target platform can be determined based on the location information of the candidate train, the location information of the target platform, the travel speed, and the train stop time in the train operation plan.

[0079] The train stop time here can be the total stop time at the platforms the train passes through when arriving at the target platform.

[0080] In one embodiment, the arrival time at the target platform=(location information of the target platform−location information of the candidate train) / travel speed+train stop time.

[0081] On this basis, the positional relationship between the candidate train and the target platform can be displayed based on the arrival time. The arrival time can be directly displayed here, for example, "This train will arrive at Station A at 10:15" can be displayed; the duration can also be determined based on the arrival time and displayed, for example, "This train will arrive at Station A in 5 minutes" can be displayed.

[0082] The method provided by the embodiment of the present invention can further improve the accuracy of information processing by determining the arrival time of the candidate train at the target platform, compared with displaying information based on the arrival time, thereby effectively improving the passenger experience.

[0083] In some embodiments, based on the arrival time, information about the positional relationship between the candidate train and the target platform is displayed, that is, step 133 specifically includes:

[0084] Step 133-1, sorting the candidate trains in order of arrival time from early to late, and determining a preset number of target trains from the candidate trains based on the sorting result;

[0085] Step 133-2, sending the information of the target train to the passenger information system, so that the passenger information system displays information about the positional relationship between the target train and the target platform.

[0086] Specifically, considering that the number of candidate trains may be large, such as 7, 8 or more trains, and passengers are more concerned about the information of candidate trains that are closer to the target platform, in order to further improve the passenger experience, a preset number of target trains can be determined from the candidate trains. The preset number here can be, for example, three or two.

[0087] Taking the case where the number of target trains is three, the target trains can be determined by sorting the candidate trains in order of arrival time from early to late, and the three trains with the earliest arrival time are selected as the target trains based on the sorting results.

[0088] After the target train is determined, the train information of the target train can be sent to the passenger information system. The target train information may include the train number, arrival time, number of stations from the target platform, current location and other information of the target train.

[0089] After receiving the information of the target train, the passenger information system can display the positional relationship between the target train and the target platform.

[0090] In some embodiments, Figure 2 FIG. 2 is a flow chart of the train information prompting method provided by the present invention. Figure 2 As shown, a train information prompting method is provided, comprising:

[0091] The central processing server locates the real-time position of the train and the train operation plan based on the train position information. If there are no online trains that are scheduled to pass through the platform but have not yet passed through the platform, the train arrival time is predicted based on the running speed, and the trains are sorted by time, and the information of the three trains that will pass through the platform is sent to the corresponding platform.

[0092] The central server updates the PIS data in real time according to the real-time position of the train. Estimated arrival time = (current platform position - current train position) / train speed + total train stop time. The train speed is the average speed over the current period of time. Average speed = travel distance / travel time.

[0093] When there is no online train information and operation plan, no information is sent to the PIS system.

[0094] In some embodiments, based on the location information of the candidate train and the location information of the target platform, information about the location relationship between the candidate train and the target platform is provided, that is, step 130 specifically includes:

[0095] Step 134, determining the distance between the candidate train and the target platform based on the position information of the candidate train and the position information of the target platform;

[0096] Step 135 , sending the distance to the broadcast system, so that the broadcast system broadcasts information about the position relationship between the candidate train and the target platform based on the distance and a preset distance threshold.

[0097] Specifically, in addition to information display, information prompts can also broadcast information. Here, the position relationship between the candidate train and the target platform is broadcast, mainly including the entry information broadcast of the candidate train about to enter the target platform, the arrival information broadcast of the candidate train arriving at the target platform, and the departure information broadcast of the candidate train leaving the target platform.

[0098] In order to trigger the broadcast system to broadcast, the distance between the candidate train and the target platform can be determined based on the location information of the candidate train and the location information of the target platform. The distance here can be expressed as: distance = target platform location - candidate train location.

[0099] After the distance is obtained, it can be sent to a broadcast system, and the broadcast system broadcasts information based on the distance and a preset distance threshold.

[0100] In specific implementation, the entry broadcast distance threshold, the arrival broadcast distance threshold and the departure broadcast distance threshold can be pre-set. When the distance between the candidate train and the target platform is within the entry broadcast distance threshold, the entry information of the candidate train can be broadcast; when the distance between the candidate train and the target platform is within the arrival broadcast distance threshold, the arrival information of the candidate train can be broadcast; when the distance between the candidate train and the target platform is within the departure broadcast distance threshold, the departure information of the candidate train can be broadcast.

[0101] It should be noted that at least one of an incoming broadcast distance threshold, an arriving broadcast distance threshold, and an outgoing broadcast distance threshold may be set here, and information corresponding to the distance threshold may be broadcasted.

[0102] The method provided in the embodiment of the present invention performs calculations based on the position information of the candidate trains, so that the entry, arrival and departure broadcasts are more accurate, and it is more convenient for passengers to understand the information such as the entry and exit of the trains.

[0103] In some embodiments, Figure 3 FIG. 3 is a flow chart of the train information prompting method provided by the present invention. Figure 3As shown, a train information prompting method is provided, comprising:

[0104] The central processing server periodically calculates the real-time position of the train, selects the trains passing through this platform, and calculates the distance between the train and the platform based on the real-time position of the train and the position of the platform. The distance from the platform = the position of the platform - the actual position of the train.

[0105] The broadcasting is controlled based on the distance between the train and the platform, the threshold for the incoming broadcast, the threshold for the arrival broadcast, and the threshold for the outgoing broadcast. The central server periodically calculates the real-time position of the train to make the incoming, arrival, and outgoing broadcasts more accurate, providing passengers with more convenient information about the train's entry and exit.

[0106] In some embodiments, after providing information prompting about the positional relationship between the candidate train and the target platform, the method further includes:

[0107] Periodically update the position information of the train to be processed, and update the candidate trains based on the updated position information;

[0108] Based on the updated position information of the candidate train, information about the position relationship between the updated candidate train and the target platform is provided.

[0109] Specifically, the train position information can be obtained periodically, and after the PIS and PA information are calculated based on the current position of the train obtained this time, the position information of the candidate train is updated based on the train position information obtained next time, and based on the updated position information of the candidate train, the position relationship between the updated candidate train and the target platform is calculated, and information prompts are provided for the updated position relationship.
