Abstract
Description
Technical Field
[0001] The present application relates to the technical field of train monitoring, and in particular to a train load monitoring method and related devices. Background Art
[0002] Overweight trains have many hazards: they will significantly increase the friction between the wheels and the tracks, increasing energy consumption while also aggravating the wear of the wheels and tracks; they will reduce the running speed and affect transportation efficiency; during emergency braking, the braking distance will be extended due to the increased inertia, which will greatly increase the risk of accidents in emergency situations; they will cause excessive loads on infrastructure such as bridges and tunnels, increasing the risk of structural damage, and in severe cases may cause structural collapse; and so on.
[0003] In the known technology, in order to prevent the danger of overweight trains, an overcrowding alarm function is set on the train: the air spring pressure value is collected, and the air spring pressure value is converted into the train weight according to an empirical formula. When the train weight exceeds the preset train weight threshold, the overweight alarm is triggered.
[0004] However, during the operation of the train, the air spring needs to automatically adjust the pressure according to the load to maintain the appropriate distance between the train body and the track. This dynamic adjustment makes the pressure value of the air spring not fully and accurately reflect the actual weight of the train. In addition, the pressure value of the air spring is also affected by many factors such as vehicle speed, curve passing, weather conditions, etc., which may lead to the misjudgment of the train being overweight. For example, when the train passes a curve at high speed, the pressure value of the air spring may change due to the centrifugal force, which may lead to the misjudgment of whether the train is overweight.
[0005] It can be seen that the accuracy of the method of monitoring whether a train is overweight based on air spring pressure in the known technology is not high. Summary of the invention

[0046] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.
[0047] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.
[0048] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0049] In the known technology, in order to prevent the danger of overweight trains, an overcrowding alarm function is set. The overcrowding alarm function is mainly triggered by an air spring pressure sensor. An air spring is a device that compresses and stores air and adjusts the height of the car body and reduces shock by releasing air.
[0050] Optional, see Figure 1 , the present application provides a flow chart showing an example of a train load monitoring method based on air spring pressure monitoring.
[0051] First, the air spring pressure sensor installed on the air spring inlet collects the air spring pressure value, and the air spring pressure sensor sends the collected air spring pressure value to the train control system; the train control system converts the air spring pressure value into the train weight according to the empirical formula, and then determines whether the train weight determined by the air spring exceeds the preset train load threshold. When it is determined that the train weight exceeds the preset train load threshold, the train control system will trigger an overcrowding alarm.
[0052] However, the method of converting the air spring pressure value into the train weight in the known technology has a relatively large error, which may lead to the misjudgment of train overweight. It should also be noted that the misjudgment of train overweight will affect the normal operation order, causing a series of problems such as train delays or passenger complaints.
[0053] With respect to the above-mentioned train load monitoring method based on air spring pressure monitoring, it can be found that there are two methods that can improve the accuracy of train load monitoring in this method.
[0054] The first is to start with air spring pressure monitoring, and improve the detection accuracy of the air spring pressure sensor so that the train weight converted from the air spring pressure value is closer to the actual weight; the second is to optimize the empirical formula mentioned above for converting the air spring pressure value into the train weight.
[0055] It should be noted that the first method of improving the monitoring accuracy of the air spring pressure sensor cannot be realized in the short term with current technology; the second method of optimizing the empirical formula requires a lot of scientific experiments. The above two methods of improving the train load monitoring method based on air spring pressure monitoring are both unrealistic to be completed in the short term.
[0056] In order to solve the problem of low accuracy in train load monitoring in the known technology, the present application provides a train load monitoring method with relatively high accuracy.
[0057] Optional, see Figure 2 , a flow chart of a train load monitoring method provided in the present application.
[0058] It should be noted that the train load monitoring method provided in the present application is specifically applied to a train control system, which monitors the train load in real time.
[0059] like Figure 2 As shown, the train load monitoring method includes the following steps:
[0060] Step 101, according to the priority of each train load monitoring mode in the train load monitoring mode set from high to low, determine whether each train load monitoring mode is effective in turn; the priority of each train load monitoring mode from high to low is the train load monitoring mode of the joint video monitoring system, the train load monitoring mode of the joint ticket information system and the train load monitoring mode based on air spring pressure monitoring; the higher the priority of each train load monitoring mode, the more accurate the corresponding train load monitoring result.
[0061] It should be noted that, the present application provides two train load monitoring methods based on the existing train load monitoring method based on air spring pressure monitoring: a train load monitoring method of a joint video monitoring system and a train load monitoring method of a joint ticket information system.
[0062] The two new train load monitoring methods provide a new train load calculation method: by obtaining the number of train passengers, the weight of the train passengers is estimated, and the train load is obtained by adding the weight of the train passengers to the weight of the empty train. In addition, the two train load monitoring methods are combined with the video monitoring system and the passenger ticket information system respectively, without the need to add any additional hardware equipment.
[0063] Specifically, the train load monitoring process of the train load monitoring method of the joint video monitoring system is as follows:
[0064] The train control system obtains real-time video data in the train from the video monitoring system. Specifically, the train control system obtains real-time video data in each carriage from the video monitoring system.
[0065] Furthermore, the train control system determines the train occupants through the video data in each carriage. Specifically, the train control system processes the video data in each carriage through a video monitoring algorithm, and the processing steps of the video monitoring algorithm include: target monitoring, target tracking, behavior recognition and face recognition processing.
[0066] Specifically, the video surveillance algorithm defines the detection area of each camera, learns the key features of passengers through the pre-established target detection model, counts the train passengers in each monitoring area, and uses the collected video surveillance data in the train compartment to establish a model training sample library of about 200,000 pictures. Through the training and optimization of the target detection model and verification in combination with experimental tests, the detection accuracy of the target detection model can reach or even exceed 95%. That is, the train control system inputs the video data into the target detection model, and the target detection model processes the video data to obtain the train passengers.
[0067] Then, the train passengers are substituted into the preset train load calculation formula to calculate the train load. Specifically, the preset load calculation formula is to multiply the train passengers by the preset per capita weight to obtain the train passenger weight, and then add the passenger weight to the pre-obtained train empty car mass to obtain the train load. Exemplarily, the preset load calculation formula can be: train passengers × per capita 80kg + measured empty car mass.
[0068] After obtaining the actual train load, it is determined whether the calculated train load exceeds a preset train load threshold. When the train load exceeds the preset load threshold, the train control system generates and sends an overcrowding alarm instruction.
[0069] The train load monitoring process based on the train load monitoring method of the joint video monitoring system is introduced. Next, the train load monitoring process based on the train load monitoring method of the joint ticket information system is introduced:
[0070] The train control system obtains the ticket information from the ticket information system. Specifically, it obtains the ticket information data from the ticket information system, determines the number of passengers through the ticket information data, and adds the number of passengers to the number of drivers and crew members scheduled to board the train to obtain the train capacity.
[0071] Then, as is the case with the processing procedure in the train load monitoring method of the above-mentioned joint ticket information system, the train passengers are substituted into the preset train load calculation formula to calculate the train load, and it is determined whether the calculated train load exceeds the preset train load threshold. When the train load exceeds the preset load threshold, the train control system generates and sends an overcrowding alarm instruction.
[0072] It should be noted that, in theory, the number of train passengers calculated by the train load monitoring method of the joint ticket information system is consistent with that of the joint video surveillance system. However, there are cases where passengers get on the train without buying tickets or buy tickets but do not get on the train, which may lead to the inconsistency between the number of train passengers calculated by the train load monitoring method of the joint ticket information system and that of the joint video surveillance system.
[0073] It is easy to understand that the train load monitoring method of the joint video surveillance system has smaller errors than the train load monitoring method of the joint ticket information system, and the train load monitoring results of the train load monitoring method of the joint video surveillance system are more accurate.
[0074] Therefore, the priority of the train load monitoring method of the joint video monitoring system is set to the highest, followed by the train load monitoring method of the joint ticket information system, and the lowest priority is the train load monitoring method based on air spring pressure monitoring. It can be understood that the higher the priority of each train load monitoring method, the more accurate the corresponding train load monitoring result.
[0075] Optionally, the train control system determines whether each train load monitoring mode is valid according to the priority order of each train load monitoring mode from high to low.
[0076] Step 102: When the video monitoring system is normal, train load monitoring is performed using a train load monitoring method of a joint video monitoring system.
[0077] The train control system first determines whether the video surveillance system is normal. If the video surveillance system is normal, the train load monitoring method of the joint video surveillance system is used to monitor the train load.
[0078] The train load monitoring method of the joint video monitoring system has been described above and will not be repeated here.
[0079] Step 103: When the video monitoring system is abnormal but the ticket information system is normal, train load monitoring is performed using the train load monitoring method of the joint ticket information system.
[0080] When the video monitoring system is abnormal, the train control system will determine whether the passenger ticket information system is normal. If the passenger ticket information system is normal, the train load monitoring method of the joint passenger ticket information system will be used to monitor the train load.
[0081] The train load monitoring method of the joint ticket information system has been described above and will not be repeated here.
[0082] Step 104: When both the video monitoring system and the ticket information system are abnormal, train load monitoring is performed using a train load monitoring method based on air spring pressure monitoring.
[0083] When both the video monitoring system and the ticket information system are abnormal, the train control system will use the train load monitoring method based on air spring pressure monitoring to monitor the train load, which has been described above and will not be repeated here.
[0084] It should be noted that the present application further provides two train load monitoring results that are better than the train load monitoring method based on air spring pressure monitoring. When either the video monitoring system or the passenger ticket information system is operating normally, the purpose of real-time monitoring of the train load can be achieved. Compared with the known technology that only uses the train load monitoring method based on air spring pressure monitoring to monitor the train load, the present application has higher reliability.
[0085] In summary, the train load monitoring method provided by the present application is applied to the train control system, and the effectiveness of each train load monitoring method is judged in the order of priority of each train load monitoring method in the train load monitoring method set. When the video monitoring system required in the train load monitoring method of the joint video monitoring system with the highest priority is normal, the train load monitoring method of the joint video monitoring system is used to monitor the train load; when the video monitoring system is abnormal but the ticket information system required in the train load monitoring method of the joint ticket information system with the medium priority is normal, the train load monitoring method of the joint ticket information system is used to monitor the train load; when the above-mentioned video monitoring system and the ticket information system are both abnormal, the train load monitoring is performed based on air spring pressure monitoring. The present application also provides two train load monitoring results with higher accuracy than the train load monitoring methods in the known technology, and the train load monitoring method with the highest accuracy is used first, thereby reducing the situation of misjudging the train overweight to a certain extent and improving the operating efficiency of the train.
[0086] For example, see Figure 3 , an example flow chart of the train load monitoring method provided in this application.
[0087] like Figure 3 As shown, when the video surveillance system and the ticket information system are both normal, the train load is calculated based on the video information in the carriage provided by the video surveillance system.
[0088] If the video monitoring system fails and the ticket information system is normal, the train load is calculated by taking the number of passengers who received the ticket information system and compensated the driver and crew. When both the video monitoring system and the ticket information system are abnormal, the train load monitoring method based on air spring pressure monitoring is adopted.
[0089] Depend on Figure 3 It can be seen that the train monitoring method of the joint video surveillance system is: after the video surveillance system collects the video information in the car, the train control system calculates the train passengers based on the video information in the car, and inputs the train passengers into the calculation formula of the train weight: number of train passengers × per person's load (including luggage, 80kg / person) + empty car mass (actual weighing mass before leaving the factory). After obtaining the train weight, it is determined whether the train weight exceeds the threshold. When it is determined that the train weight exceeds the threshold, the train control system triggers an overcrowding alarm.
[0090] Depend on Figure 3It can be seen that the train load monitoring method of the joint ticket information system is: the ticket information system counts the train ticket information, the train control system receives the train ticket information, and compensates the number of drivers and crew members to calculate the train capacity, and inputs the train capacity into the train weight calculation formula: number of train passengers × per person load (including luggage, 80kg / person) + empty car mass (actual weighing mass before leaving the factory). After obtaining the train weight, it is determined whether the train weight exceeds the threshold. When it is determined that the train weight exceeds the threshold, the train control system triggers an overcrowding alarm.
[0091] Depend on Figure 3 It can be seen that in the train load monitoring method based on air spring pressure monitoring, the train control system collects the air spring pressure value from the air spring pressure sensor, converts the air spring pressure value into the train weight according to the formula, and determines whether the train weight exceeds the threshold. When it is determined that the train weight exceeds the threshold, the train control system triggers the overcrowding alarm.
