Description
Technical Field
The application relates to the technical field of operation and maintenance of rail transit vehicles, in particular to a data reporting method and a vehicle-mounted monitoring system of a railway wagon.
Background
In order to carry out operation and maintenance on the railway wagon, condition monitoring on the railway wagon is generally required. At present, a vehicle-mounted monitoring system can be additionally arranged on a vehicle, so that running state data such as tension, pressure, vibration and the like during running of the vehicle are collected and analyzed, and data and alarm are sent to a data platform.
Due to installation and operation conditions, the on-board monitoring system of the railway wagon can generally only supply power through a battery, and real-time data is sent to a remote data platform through a wireless module. Because the wireless module sends data which greatly affects the electricity consumption, the prior proposal only monitors and does not send data in the running process of the vehicle, or sends alarm data to the cloud platform of the remote monitoring center only when the vehicle has a fault, and leads out the running data for analysis by manpower regularly, thus having the defects of poor real-time performance and complex maintenance when the original monitoring data is obtained.
The main difficulty in obtaining the running data of the rail wagon in real time is that the vehicle-mounted monitoring battery power is consumed quickly when continuously monitoring and reporting data, and the maintenance-free purpose of the vehicle-mounted monitoring battery power for years is difficult to achieve. Some other schemes provide that a power generation device is additionally arranged to solve the power supply problem of the monitoring system, although long-time monitoring and data reporting can be realized, each monitoring module needs to be connected with a power supply in a wired mode, the fault possibility is increased under the severe truck using environment, and meanwhile, the additionally arranged power supply device also increases the complexity of the system and influences the reliability of the whole system.
When no power supply is used, a fixed time interval or a fixed distance interval is set in the whole running process of the vehicle, and data is reported when the time or the distance is reached. In order to reduce power consumption, the time interval or the distance interval is generally set to a larger value, which has a disadvantage that the important monitoring area is easily missed, and thus the utility of the reported data is not high.
Based on the analysis, how to save the power consumption of the reported data of the vehicle-mounted monitoring system and improve the real-time performance and effectiveness of the state monitoring of the railway wagon becomes a technical problem which needs to be solved urgently in the current field.

Detailed Description
As described above, when the current vehicle-mounted monitoring system of a railway wagon needs to report monitored wagon running state data, power consumption is high, a power generation device needs to be specially additionally installed to solve the problem of power supply of the monitoring system, and the complexity of the system is increased and maintenance is inconvenient after the power generation device is introduced. In order to save power consumption, the running data analysis can be periodically derived by manpower, but the defects of poor instantaneity and complex maintenance of the obtained original monitoring data exist. In addition, data reporting can be performed by lengthening the time interval or the distance interval for reporting data, but the important monitoring area is easily missed, so that the data utility is not high.
Based on the above problems, the inventor provides a data reporting method and a vehicle-mounted monitoring system for a railway wagon through research. In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Method embodiment
Referring to fig. 1, the figure is a flowchart of a data reporting method for a railway wagon according to an embodiment of the present application. The data reporting method shown in fig. 1 includes:
step 101: obtaining the position of a monitoring point; the monitoring point is a point on a key monitoring section of the running route of the railway wagon.
In the embodiment of the application, the important monitoring sections are defined in advance or obtained through analysis. The focus monitoring section may be a curve section or a switch section, which requires significant attention during operation of the railway wagon. The operation route can comprise one or more important monitoring sections, and each important monitoring section comprises one or more monitoring points. Step 101 is to obtain the positions of all monitoring points. The number of monitoring points is not limited in the embodiment of the application. In step 102 described later, the monitoring point specifically refers to any one of the monitoring points indicated in step 101.
Step 102: when the railway wagon is in formal operation on the operation route, and the position of the vehicle-mounted host on the railway wagon is matched with the position of the monitoring point, the host is triggered to report the acquired operation state data of the railway wagon to the data platform.
Because the host computer is provided with the positioning sensor, the host computer can obtain the position of itself. And (4) combining the position of the monitoring point obtained in the step (101), the host can judge whether the position of the host is matched with the position of the monitoring point in real time.
In a possible implementation manner, the matching of the position of the host and the position of the monitoring point means that the position of the host and the position of the monitoring point are consistent. In this implementation, once the positions are matched, the host may report all the operation state data of the railway wagon, which is obtained in real time, to the data platform.
In another possible implementation, the location of the host matches the location of the monitoring point, meaning that the host is located near the monitoring point. That is, once the host is located near the watch point, the location of the host is considered to match the location of the watch point. When the host enters the vicinity of the monitoring point along with the running of the truck, the host can acquire the running state data of each carriage and upload the data to the data platform. At this time, the uploaded running state data of each compartment also has high real-time performance, and the data content of the running state data is matched with the monitoring points and the key monitoring sections.
In the embodiment of the application, the data platform can be a platform which is built by a hardware entity and has the operation and data transmission capabilities, and can also be a cloud platform. The form of the data platform is not limited herein.
The above is the data reporting method provided in the embodiment of the present application. In the method, when the position of the truck-mounted host of the railway truck is matched with the position of the monitoring point, the host reports the running state data of the truck to the data platform, so that the data reporting does not need to consume power frequently. In addition, the monitoring points are in the important monitoring section, and the data effectiveness is high. And the reported data is also matched with the time of the truck passing the monitoring point, so that the real-time performance of the data is high. Therefore, the scheme can save the power consumption of the reported data and improve the real-time performance and effectiveness of the monitoring of the state of the railway wagon.
The following describes an implementation manner of selecting a monitoring point in conjunction with another embodiment. Before describing this implementation, an on-board monitoring system will first be described. The vehicle-mounted monitoring system comprises the host computer, and also comprises monitoring sensors and gateways arranged in all carriages of the railway wagon. The specific type of monitoring sensor is not limited in this application. For example, it may be a sensor for monitoring the data of the operating state such as pressure, tension, vibration, etc. The data collected by the sensor needs to be sent to the gateway, the gateway is in butt joint with the host, and the gateway sends the running state data of the carriage to which the gateway belongs to the host.
Referring to fig. 2, a flowchart of another method for reporting data of a railway wagon according to an embodiment of the present disclosure is shown. The data reporting method shown in fig. 2 includes:
the process of generating the operation route is performed in the following steps 201 and 204.
Step 201: during the whole experimental running period of the railway wagon on the primary route, the positions of a plurality of positioning points on the primary route are obtained by utilizing the positioning sensors.
First, in order to generate an accurate operation route, experimental operation with a railway wagon on a preliminary route is required. During the period, the data does not need to be reported in real time, because the operation is not in a formal operation stage, and the position information of the monitoring point is not available. In the whole running process, the positioning on the vehicle-mounted monitoring system host computer is initiated to obtain and record the position of the positioning point in real time. The positioning points are selected according to a preset frequency. For example, one anchor point may be recorded every second. In addition, the positioning points can be uniformly selected in a time dimension or a distance dimension. The positions of these anchor points are matched with the anchor points one by one, and there is further processing, see step 202.
Step 202: and filtering the positioning points according to preset filtering conditions to obtain a plurality of residual positioning points after filtering, and configuring the positions of the plurality of residual positioning points after filtering to the data platform.
The whole course of running the initial route in the experimental stage of the railway wagon may consume tens of hours or even days, so that the data volume of the positioning point is too large. This is not very necessary for choosing the monitoring point. In order to reduce the data amount, the anchor point recorded in step 201 may be filtered by a preset filtering condition. The anchor points may be filtered, for example, by a distance threshold. The distance here does not refer to a straight line distance but to a distance along the preliminary route.
When the distance between a positioning point and the last positioning point is smaller than the distance threshold, skipping the point (being filtered), and so on, until reaching the specified distance threshold, determining the next positioning point which is not filtered. The distance threshold can be set according to the length of the whole route and the precision requirement of a sampling point, and the distance threshold is set to be 100 meters. That is to say, the distance between the two front and back positioning points is not less than the distance threshold. Through the step, a plurality of positioning points are filtered, and the positions of the rest positioning points can be configured to the data platform and then processed by the data platform.
Step 203 and 205 may be performed by the data platform.
Step 203: and generating a running track on the electronic map according to the positions of the plurality of positioning points which are left after filtering.
An electronic map is integrated on the data platform in advance. In this step, according to the positions of the positioning points remaining after the filtering in step 202, a running track can be generated on the electronic map based on the positions of the positioning points. The coordinate system supported by the electronic map may be different from the coordinate system of the position of the acquired positioning point, in which case the data platform is required to support coordinate transformation so that the position of the positioning point may be transformed into a coordinate system matched with the electronic map.
Step 204: and removing the duplication of the running track, and removing the positioning points on the repeated track to obtain the running route.
When the experimental vehicle runs, multiple times of repeated running are likely to occur, for example, the experimental vehicle runs back and forth on a certain section of line, or repeatedly runs on a certain section of line due to fork scheduling, avoidance of other trucks and the like. Therefore, in order to ensure that a running route with higher accuracy is generated, the anchor point on the repeated track is required to be attached to the running track generated in the previous step 203 in this step. Through the execution of the step, the accurate vehicle running route is obtained.
Step 205: displaying the running route; and responding to the clicking operation acting on the displayed running route, determining the position of the monitoring point, and sending the position of the monitoring point to the host.
The generated travel route is presented on an electronic map. The data platform can display the electronic map and the running route on the electronic map through equipment such as a display screen. And the data platform can respond to click operation manually acted on the running route. Based on the operation, the position of a positioning point on the running route, which is closest to the position of the click operation, is determined, and the positioning point is used as a monitoring point. The location point on the travel route may be shown in some specific way, for example a drop-shaped graphic indicating the location point. Since the position of the click operation does not necessarily coincide with the position of a certain positioning point, in order to ensure the accuracy of selecting the monitoring point, it is necessary to determine the position of the positioning point closest to the position of the click operation and use the positioning point as the monitoring point.
Specifically, the user may visually determine the focused monitoring zone according to the displayed travel route. In other possible implementations, the emphasized monitoring sections may also be displayed in a specific manner, for example, the emphasized monitoring sections are red, and the other non-emphasized monitoring sections are blue, so that the importance of section monitoring is shown by the difference of colors. Furthermore, the user can execute the clicking operation according to the key monitoring section of the displayed running route.
Fig. 3 is a schematic diagram of selecting monitoring points on an electronic map of a data platform. The monitoring points are distributed near the turnout or the curve. After clicking a certain position, the related information of the positioning point closest to the position, such as the number, the coordinates, the GPS coordinates and the acquisition time, can be displayed. In addition, the following functional operations can be performed on the positioning point (i.e. monitoring point): delete, select as a starting point, range, track, display point of interest, clear all, etc.
Step 206: the host computer obtains the position of the monitoring point.
In this embodiment, the host machine is located in the first car behind the locomotive in the direction of travel.
Step 207: and obtaining the time of the whole length of the railway wagon passing the monitoring point according to the whole length and the real-time speed of the railway wagon.
The host has a data reporting mode, and when the data reporting mode is started, the host can report the running state data monitored by the monitoring sensor to the data platform. If the data reporting mode is closed, the function of reporting data to the data platform by the host can be understood to be in a sleep state. In order to effectively control the data reporting mode to be started only in necessary time, the time of the railway freight car passing through a certain monitoring point in the whole field is obtained according to the whole length and the real-time speed of the railway freight car in the step. If the speed of the vehicle is different at a plurality of monitoring points and different road sections, the time of passing each monitoring point needs to be calculated respectively.
The effect of the time obtained in step 207 is described below with particular reference to step 208.
Step 208: during the formal running period of the railway wagon on the running route, when the position of a vehicle-mounted host on the railway wagon is matched with the position of a monitoring point, triggering a data reporting mode of the host to start and time, acquiring running state data of each carriage forwarded by a gateway of each carriage, reporting the running state data of each carriage to the data platform until the time length reaches the time, and closing the data reporting mode.
Since the host is located in the first carriage behind the locomotive in the driving direction, the data reporting mode of the host can be triggered to be started when the position of the host coincides with the position of a certain monitoring point a (taking the monitoring point a as an example, the monitoring point a is not shown in the figure). At this moment, the host can upload the running state data of the compartment forwarded by each gateway. And sequentially uploading the data forwarded by the gateway of each carriage in the sequence to the data platform by the host according to the sequence that each carriage passes through the monitoring point. When the data reporting mode on time reaches the time obtained in step 207, it indicates that the last car of the whole railway wagon should just pass the monitoring point a. At this point, it is no longer necessary to upload data, since the entire vehicle has been completely removed from monitoring point a. Therefore, the data reporting mode of the host can be closed, so that the host can sleep again, and the continuous data uploading power consumption is avoided.
In the above embodiments, only the implementation manner and the reporting time for reporting data when the host is located in the first carriage in the operation direction are described. In other possible implementation manners, since the host computer may also be disposed at other locations, for example, at a car with a middle number, the host computer may continuously collect data in a section of area before and after the monitoring point instead of collecting data only once at the monitoring point, so as to ensure that the reported data includes data of each vehicle of the full truck at the monitoring point.
Based on the data reporting method of the railway wagon introduced in the embodiment, correspondingly, the application further provides a vehicle-mounted monitoring system of the railway wagon. This system is described below.
