Description

Technical Field

[0001] The present invention relates to the field of high-speed trains, and in particular to a high-speed train passenger comfort visualization system and an evaluation method based on multi-source data. Background Art

[0002] As people's requirements for travel quality continue to increase, the comfort of riding on high-speed trains has attracted more and more attention from passengers. In the existing technology, the evaluation method for high-speed train passenger comfort mostly uses the lateral and vertical acceleration indicators of the car body for macroscopic judgment. This type of judgment method is difficult to meet the refined needs of different passenger characteristics (age, gender, etc.) for train comfort, and cannot reflect the different adaptability of different passenger characteristics to train comfort. The guiding significance for optimizing the running comfort of high-speed trains is relatively weak. Therefore, it is urgent to carry out research on comfort test methods that take into account different passenger characteristics. Summary of the invention

[0003] The present invention provides a high-speed train passenger comfort visualization system and evaluation method based on multi-source data to solve the problem that the prior art cannot reflect the different needs and adaptability of different passengers for train comfort, and can achieve corresponding comfort evaluation results for different passenger characteristics, so as to complete the evaluation and research of high-speed train comfort in a more refined manner, and provide scientific and reasonable data support for the optimization of high-speed train operation comfort.

[0004] The present invention is achieved through the following technical solutions:

[0005] High-speed train passenger comfort visualization system based on multi-source data, including:

[0006] Real-name identity verification module: used to verify the real-name information of passengers and obtain the age and gender characteristics of passengers;

[0007] Multi-source data acquisition module: used to collect multi-source data representing the physical condition of passengers in real time; the multi-source data includes any one or more of body temperature, heart rate, and blood oxygen;

[0008] Passenger comfort threshold acquisition module: used to obtain the comfort threshold and / or medical health threshold corresponding to the passenger's age and gender characteristics.

[0009] Passenger comfort warning module: based on the comfort threshold and / or medical health threshold, compares with the multi-source data, and issues a prompt signal according to the comparison result;

[0010] Passenger comfort visualization module: located in front of the passenger seat, used to display the multi-source data in real time, receive the prompt signal, and display warning information.

[0011] In view of the problem that the existing technology cannot reflect the different needs and adaptability of different passenger characteristics for train comfort, the present invention first proposes a high-speed train passenger comfort visualization system based on multi-source data. The system verifies the real-name information of the passenger sitting in the designated seat through the real-name identity authentication module, and obtains the age and gender characteristics of the passenger after the verification; the multi-source data collection module collects a multi-source data set that can characterize the passenger's physical state in real time, wherein the multi-source data includes but is not limited to any one or more of body temperature, heart rate, and blood oxygen. The collected multi-source data is sent to the passenger comfort warning module; the inventor of this case found in the research process that for passengers of different ages and gender characteristics, their comfort feelings when riding the train have obvious differences. Therefore, this solution needs to obtain the corresponding comfort threshold and / or medical health threshold under the age and gender characteristics of the current passenger through the passenger comfort warning module, and then compare the multi-source data obtained by real-time monitoring with the comfort threshold and / or medical health threshold. If the multi-source data received in real time does not meet the range of the comfort threshold and / or medical health threshold, a prompt signal is sent to the passenger comfort visualization module. In this application, the comfort threshold and / or medical health threshold under different age and gender characteristics are obtained based on the passenger comfort threshold acquisition module. The passenger comfort visualization module is set in front of the passenger seat, such as on the backrest of the front seat; for the first row of seats, it can be set on the inner wall of the train compartment; this system displays the acquired multi-source data in real time on the passenger comfort visualization module, so that passengers can accurately grasp their physical condition during the high-speed train ride, and when a data indicator exceeds the corresponding threshold range, the warning information is displayed in time.

[0012] The medical health threshold in this application refers to the data range that is at a medically normal level, such as the normal range of body temperature, the normal range of heart rate, etc., which can be set through experience or based on the advice of professional medical institutions.

[0013] The present application abandons the technical idea of ​​indirectly evaluating passenger comfort by using macroscopic indicators of train operation in the prior art, and instead directly collects multi-source data related to the passengers' perceived comfort during the ride as evaluation indicators. This can fully reflect the differences in the adaptability of different passenger characteristics to train comfort, meet the refined needs of different passenger characteristics for train comfort, and more accurately and reasonably complete the evaluation of high-speed train comfort, providing scientific and reasonable data support for the optimization of high-speed train operation comfort.

[0014] Furthermore, the real-name identity verification module includes:

[0015] A face image acquisition unit: embedded in the passenger comfort visualization module, used to acquire the actual face image of the passenger in the designated seat;

[0016] Identity acquisition unit: used to obtain the ID card information of the passenger who purchased the designated seat on the current train, and extract the ID card head portrait data, age and gender;

[0017] Identity verification unit: used to compare the passenger's actual facial image with the ID card portrait data.

[0018] In this solution, the actual facial image of the passenger in the designated seat is collected by the face image acquisition unit; the identity acquisition unit can obtain the ID card information of the passenger who purchases the corresponding seat on the current train from the real-name ticket purchase system of the railway system, and extract the ID card head portrait data, age and gender therein; the identity authentication unit compares the collected actual facial image of the passenger with the extracted ID card head portrait data, and the comparison method can be implemented based on the existing mature image comparison or image recognition technology, which is not difficult to implement for those skilled in the art; when the comparison result of the identity authentication unit matches, the real-name identity authentication module completes the verification of the passenger's real-name information; on the contrary, if the verification fails, the system can send a corresponding prompt message to the train crew. In addition, this solution can directly extract accurate age and gender characteristics from the passenger's ID card information through the identity acquisition unit, which significantly improves the accuracy of judging age and gender compared to the method of judging the age and gender of passengers by image recognition technology, avoids the recognition error of age and gender by image recognition technology, and ensures the accuracy of the subsequent selection of the corresponding comfort threshold and / or medical health threshold.

[0019] Furthermore, the multi-source data acquisition module includes:

[0020] Non-contact body temperature collection unit: embedded in the passenger comfort visualization module, collecting passenger temperature data based on an infrared thermometer;

[0021] Non-contact heart rate collection unit: based on the actual facial image of the passenger, collects the passenger's heart rate data by photoplethysmography;

[0022] Non-contact blood oxygen collection unit: embedded in the surface of the seat armrest, it collects the passenger's blood oxygen value based on a reflective blood oxygen sensor.

[0023] Infrared temperature measurement, imaging photoplethysmography (iPPG), and reflective blood oxygen sensor are all existing non-contact detection technologies. When used in this system, it is possible to obtain passengers' body temperature, heart rate and blood oxygen data without affecting the ride comfort, thereby providing accurate data indicators for judging and evaluating the comfort of passengers.

[0024] Furthermore, the passenger comfort threshold acquisition module includes:

[0025] High-speed rail environment simulation platform: used to simulate the high-speed train operating environment and obtain comfort thresholds under different age and gender characteristics;

[0026] Questionnaire survey module: used to obtain the subjective comfort scores of testers on the high-speed rail environment simulation platform in several different vibration environments and noise environments;

[0027] Data acquisition module: used to collect multi-source data of test status of test personnel on the high-speed rail environment simulation platform in several different vibration environments and noise environments;

[0028] Data analysis module: used to associate the test status multi-source data with the subjective comfort score to obtain a comfort threshold.

[0029] In this solution, the high-speed train operating environment is simulated through the high-speed rail environment simulation platform, and based on a large amount of test data, the comfort threshold of people with different age and gender characteristics in the simulated high-speed train operating environment is obtained. The comfort threshold collects the subjective comfort score of the test personnel through a questionnaire survey, and collects multi-source data under the test state through the data acquisition module. Then, the subjective comfort score and the multi-source data under the test state are combined to obtain the comfort threshold; this method can significantly improve the objectivity of the comfort threshold and reduce the interference of subjective factors on the comfort threshold. This application saves a large number of comfort thresholds obtained in the threshold storage unit, and the medical health thresholds obtained can also be saved in the threshold storage unit; when the system is working, the early warning judgment unit retrieves the corresponding comfort threshold and medical health threshold from the threshold storage unit according to the age and gender of the current passenger, and uses this as the basis for the evaluation of the passenger to carry out work, which fully meets the needs of differentiated evaluation of the comfort of different individuals.

[0030] Furthermore, the high-speed rail environment simulation platform includes:

[0031] Train vibration environment simulation device: used to simulate the vibration environment during the operation of high-speed trains;

[0032] Test seat: of the same model and size as the train seat, installed on the train vibration environment simulation device;

[0033] Noise environment simulation device: used to simulate the noise environment during the operation of high-speed trains.

[0034] Furthermore, the passenger comfort warning module includes:

[0035] Threshold storage unit: used to store several comfort thresholds and medical health thresholds under different age and gender characteristics;

[0036] Real-time data receiving unit: used to receive multi-source data representing the passenger's physical status in real time;

[0037] Early warning judgment unit: used to compare the multi-source data received in real time with the comfort threshold and medical health threshold based on the age and gender characteristics of the current passenger; if any of the multi-source data received in real time exceeds the corresponding comfort threshold or medical health threshold, a warning signal is issued.

[0038] This plan clearly defines the high-speed rail environmental simulation platform. Specifically, a train vibration environment simulation device is established to simulate the vibration environment during the operation of a high-speed train, and a test seat is installed on the train vibration environment simulation device. The test seat uses the same material, model and size as the train whose comfort is to be evaluated to reduce the interference of objective conditions.

[0039] When it is necessary to determine the comfort threshold, a large number of testers of different genders and ages are arranged to sit on the test seats in turn, and the vibration environment during the operation of the high-speed train is simulated by the train vibration environment simulation device, and the noise environment during the operation of the high-speed train is simulated by the noise environment simulation device; in this process, the multi-source data of the testers are collected and recorded by the data acquisition module, which is recorded as the test status multi-source data. The questionnaire survey module conducts a questionnaire survey on the testers' perceived comfort, which can be conducted after the test is completed or during the test process to obtain the subjective comfort score of each tester; then, the data analysis module associates the test status multi-source data of each tester with the subjective comfort score to obtain the corresponding comfort threshold range for each tester; the large amount of data obtained is screened and processed to eliminate the obviously deviated outliers, and the mean or other statistical values ​​that can represent the vast majority of testers are taken from the remaining values, which can be used as the comfort threshold under the corresponding age and gender characteristics.

[0040] Furthermore, the passenger comfort visualization module includes:

[0041] Display unit: installed on the back of the front seat or hung on the wall of the train compartment, used to display the multi-source data in real time and display an early warning after receiving a prompt signal;

[0042] Human-computer interaction unit: integrated in the display unit, used for information interaction with passengers.

[0043] For the seats in the first row, the corresponding display units can be hung on the train compartment wall, and the display units corresponding to the remaining seats are preferably installed on the backs of the front seats, so that the collected multi-source data can be displayed in real time for passengers to watch intuitively. The display unit in this solution integrates a human-computer interaction unit, which can be implemented by a touch display screen or a display screen with a case, so as to facilitate information interaction with passengers.

[0044] Furthermore, the human-computer interaction unit includes:

[0045] Permission management submodule: used to set access rights for the multi-source data; passengers can set access rights for train staff or backend according to personal needs to meet data privacy security.

[0046] Data backtracking submodule: used to backtrack the multi-source data of the current passenger during this ride; the backtracking method is preferably displayed intuitively in the form of a curve chart or a line chart, so that passengers can review their physical condition data during the ride.

[0047] Report sharing submodule: used to generate a comfort report for the current passenger during the ride, and send the comfort report to the corresponding passenger after the current passenger arrives at the terminal. Passengers can enter the corresponding email address and mobile phone number through the report sharing submodule to facilitate the subsequent receipt of the comfort report, or receive the comfort report through the public account push after scanning the code. The specific content of the comfort report recorded in this solution can be adaptively set by the user, such as including a complete set of multi-source data during the ride, the time and place when the multi-source data does not meet the comfort threshold and / or medical health threshold, etc. The specific content of the comfort report does not fall within the scope of protection requested by this application and is not limited in detail here.

[0048] Furthermore, it also includes a data transmission module, which communicates wirelessly with the vehicle-mounted receiving terminal.

[0049] The on-board receiving terminal in this solution can be set up in the train control room, or in the crew studio of a designated carriage, or be equipped to designated crew members in the form of a portable terminal, so that the staff can quickly grasp the comfort evaluation of different passengers, and in special circumstances, such as when one or more multi-source data exceeds the medical health threshold, the train staff can be prompted and corresponding emergency measures can be taken in time, which is conducive to improving the safety of passengers.

[0050] The comfort evaluation method based on the high-speed train passenger comfort visualization system in this application includes:

[0051] After the train starts, the real-name identity verification module verifies the real-name information of the passenger. After the verification is passed, the age and gender characteristics of the passenger are obtained and sent to the passenger comfort warning module;

[0052] During the operation of the train, the multi-source data acquisition module collects the multi-source data in real time and sends it to the passenger comfort warning module;

[0053] The passenger comfort warning module obtains the comfort threshold and / or medical health threshold corresponding to the age and gender characteristics of the current passenger based on the age and gender characteristics, and compares it with the multi-source data received in real time; if the multi-source data received in real time does not meet the range of the comfort threshold and / or medical health threshold, a prompt signal is sent to the passenger comfort visualization module;

[0054] The passenger comfort visualization module displays the multi-source data in real time, and displays warning information after receiving the prompt signal.

[0055] Furthermore, when the multi-source data received in real time does not meet the range of the comfort threshold and / or the medical health threshold, the passenger comfort warning module also sends a prompt signal to the vehicle-mounted receiving terminal through the data transmission module.

[0056] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0057] 1. The high-speed train passenger comfort visualization system and evaluation method based on multi-source data of the present invention abandons the technical idea of ​​indirectly evaluating passenger comfort by using macro-indicators of train operation in the prior art, and instead directly collects multi-source data related to the somatosensory comfort of passengers during the ride as evaluation indicators.

[0119] When it is necessary to determine the comfort threshold, a large number of testers of different genders and ages are arranged to sit on the test seats in turn, and the vibration environment during the operation of the high-speed train is simulated by the train vibration environment simulation device, and the noise environment during the operation of the high-speed train is simulated by the noise environment simulation device; in this process, the multi-source data of the testers are collected and recorded by the data acquisition module, which is recorded as the test status multi-source data. The questionnaire survey module conducts a questionnaire survey on the testers' perceived comfort, which can be conducted after the test is completed or during the test process to obtain the subjective comfort score of each tester; then, the data analysis module associates the test status multi-source data of each tester with the subjective comfort score to obtain the corresponding comfort threshold range for each tester; the large amount of data obtained is screened and processed to eliminate the obviously deviated outliers, and the mean or other statistical values ​​that can represent the vast majority of testers are taken from the remaining values, which can be used as the comfort threshold under the corresponding age and gender characteristics.

[0120] In a more preferred embodiment, the data analysis module associates the test state multi-source data with the subjective comfort score by the following method:

[0121] Step 1: Determine the basic information of the tester; the basic information includes age, gender and occupation;

[0122] Step 2: Set the vibration environment (such as level 1, 2, 3, 4, 5) and noise environment (such as level 1, 2, 3, 4, 5) of the high-speed rail environment simulation platform;

[0124] Step 4: Pause after the test is set, and fill in the questionnaire of the test according to the subjective feelings of the tester; the questionnaire includes: vibration environment score (0-30 points are very uncomfortable, 31-60 points are relatively uncomfortable, 61-80 points are comfortable, and 81-100 points are very comfortable); noise environment score (0-30 points are very uncomfortable, 31-60 points are relatively uncomfortable, 61-80 points are comfortable, and 81-100 points are very comfortable).

[0125] Step 5: Adjust the vibration environment and noise environment of the high-speed rail environment simulation platform, repeat steps 3 and 4, and obtain the questionnaire results of the testers in different vibration environments and noise environments;

[0126] Step 6: Establish a health data-comfort curve based on the questionnaire results of the testers in different vibration environments and noise environments; for example, using comfort as the horizontal axis and health data as the vertical axis, fit the point values ​​corresponding to the questionnaire results of the testers in different vibration environments and noise environments to obtain the required health data-comfort curve;
