Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a method, device, equipment, and medium for adjusting a directional antenna on a railway train. Background Art

[0002] Antennas play a key role in communication systems. Currently, most railway communication antennas are installed with a fixed direction. Although directional antennas have better communication quality, their greatest limitation lies in their immobility after installation. Once the antenna is fixed at a specific position, it cannot be flexibly adjusted according to actual needs or environmental changes, which to a certain extent limits the flexibility and adaptability of the communication system. Especially in complex and changeable communication environments, fixed antennas may not always ensure the best signal reception and transmission effects. In addition, fixed antennas may face signal interference problems in specific application scenarios. For example, in densely populated urban areas, due to the obstruction of buildings, wires, and other obstacles, fixed antennas may not be able to receive stable signals, resulting in a decline in communication quality. In some remote areas or complex terrains, fixed antennas may not be able to provide sufficient signal coverage. For example, at the curved sections of the train tracks, the application range of the communication system is limited.

[0003] To avoid collision events between different trains traveling on the same track, communication needs to be carried out between the front and rear trains on the same track to inform each other of train information. Since this type of communication is between fixed targets, a directional antenna communication method is adopted to improve communication quality. However, at the curved sections of the train tracks, the fixed angle of the directional antenna limits the communication quality between trains. Summary of the Invention

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0030] Figure 1 The embodiment of the present invention provides a flowchart of a method for adjusting a directional antenna on a railway train. This embodiment is applicable to the situation of adjusting the angle of the directional antenna used for communication between trains running on the same track. This method can be executed by a device for adjusting the directional antenna on a railway train. The device for adjusting the directional antenna on a railway train can be implemented in the form of hardware and / or software, and the device for adjusting the directional antenna on a railway train can be configured in a target train. As Figure 1 shown, the method includes:

[0031] S110. Determine the initial alignment angle of the target directional antenna on the target train.

[0032] Among them, the initial alignment angle is determined according to the reference angle of the matching directional antenna on the reference train on the same track.

[0033] The target train and the reference train are the front and rear trains running on the same track. For example, the target train runs in front of the reference train, or the target train runs behind the reference train. In order to avoid collision events between different trains running on the same track, the front and rear trains on the same track need to communicate with each other to inform each other of train information. Since this kind of communication belongs to the communication between fixed targets, the communication method using directional antennas is adopted to improve the communication quality.

[0034] Specifically, a communication connection is established between the target directional antenna on the target train and the matching directional antenna on the reference train. When the target train departs, the initial alignment angle of the target directional antenna on the target train is determined according to the reference angle of the corresponding matching top-line antenna on the reference train, so as to ensure that the communication quality between the target directional antenna and the corresponding matching directional antenna is the best at the initial alignment angle.

[0035] Exemplarily, the target train is the train that departs at an earlier time, and the reference train is the train that departs at a later time. When the target train departs, it determines the initial alignment angle of the target directional antenna according to the track direction. Similarly, the reference train also determines the reference angle of the matching directional antenna according to the track direction, so as to achieve the angle alignment between the target directional antenna on the target train and the corresponding matching directional antenna, and achieve the best communication.

[0036] In a feasible embodiment, the target train includes a first target directional antenna and a second target directional antenna; the first target directional antenna is located at the front end of the target train and communicates with the directional antenna located at the rear end of the front reference train on the same track in a matching manner; the second target directional antenna is located at the rear end of the target train and communicates with the directional antenna located at the front end of the rear reference train on the same track in a matching manner.

[0037] As Figure 2 Shown is a schematic diagram of trains running on the same track. Each train includes two directional antennas. The first directional antenna is located at the front of the train, and the second directional antenna is located at the rear of the train; the first target directional antenna located at the front of the target train communicates with the second directional antenna located at the rear of the front reference train in a matching manner, that is, the initial alignment angle of the first target directional antenna located at the front of the target train is determined according to the initial angle of the second directional antenna located at the rear of the front reference train; the second target directional antenna located at the rear of the target train communicates with the first directional antenna located at the front of the rear reference train in a matching manner, that is, the initial alignment angle of the second target directional antenna located at the rear of the target train is determined according to the initial angle of the first directional antenna located at the front of the rear reference train.

[0038] By matching and communicating the two directional antennas on each train with the corresponding directional antennas on the front and rear trains respectively, efficient and accurate communication between trains on the same track is achieved.

[0039] S120. Obtain the current running track image collected by the image acquisition device on the target train, and determine the track angle change information according to the current running track image.

[0040] Among them, the track angle change information is used for the change information of the track direction of the target train's current running and the initial track direction. Exemplarily, since the initial alignment angle is determined when the target train departs, the initial track direction of the target train at the departure time is determined at the same time. The current track direction is determined according to the current running track image during the running of the target train, and the track angle change information is determined according to the current track direction and the initial track direction. For example, the initial track direction and the current track direction are direction information in the world coordinate system, thereby ensuring the benchmark consistency of the track angle change information and improving the accuracy of the determination result.

[0041] At least one image acquisition device is provided on the target train for acquiring the track image of the current travel of the target train. Specifically, a camera device is provided at the front end and / or the rear end of the target train for photographing and acquiring the travel track during the travel of the target train. Exemplarily, the current travel track image of the target train is acquired at a preset time interval.

[0042] Determine the track angle change information between the track angle of the target train and the historical track angle according to the track information in the current travel track image. Exemplarily, identify the track boundary in the current travel track image, and determine the track angle change information according to the angle information of the track boundary. The image acquisition field of view of the image acquisition device is determined according to the adjustment range of the track angle.

[0043] Exemplarily, after determining the track angle change information, the angle of the image acquisition device is also adjusted accordingly to achieve complete coverage acquisition of the travel track by the image acquisition device, and avoid missing track information in the acquired travel track image.

[0044] In a feasible embodiment, determining the track angle change information according to the current travel track image includes:

[0045] Identify the current travel track image to obtain track boundary information and track center information;

[0046] Determine the track angle change information according to the change information of the track boundary information and the track center information.

[0047] Perform track boundary recognition on the current travel track image to obtain track boundary information, determine track center information according to the track boundary information, and determine the track angle change information according to the change information of the track boundary information and the track center information in the current travel track image and the track boundary information and the track center information in the historical travel track image.

[0048] Exemplarily, according to the track boundary information and the track center information of the current travel track image, convert to the world coordinate system to determine the current track travel direction; according to the track boundary information and the track center information in the initial travel track image, convert to the world coordinate system to determine the initial track travel direction, and determine the track angle variability information according to the current track travel direction and the initial track travel direction.

[0049] Exemplarily, computer vision technology is used to analyze the current running track image, identify the track targets of the target train, and output the bounding boxes of each detected track target. Calculate the center point coordinates of the target track according to the coordinates of the bounding box. If the upper left corner coordinates of the bounding box are (Xmin, Ymin) and the lower right corner coordinates are (Xmax, Ymax), the center point can be calculated as: centerX = (Xmin + Xmax) / 2; centery = (Ymin + Ymax) / 2. Set the internal parameters of the camera (such as focal length, principal point position, distortion coefficient, etc.), and convert the image coordinates into coordinates in the world coordinate system through these parameters. Calculate the relative position with the target: If the relative position between the camera and the antenna is known, the position of the target track in three-dimensional space can be calculated through triangulation. Assume that the camera is at a certain fixed position (such as the origin), and then convert the image coordinates of the target track into coordinates in the internal image coordinate system of the camera. Calculate the relative angle of the target track: After determining the coordinates of the target in the internal coordinate system of the camera, further calculate the angle of the target track relative to the antenna. Assume that the direction of the antenna is a certain fixed direction (such as the X-axis), and the relative position of the target track is (dx, dy), where dx and dy are the coordinate differences of the target track relative to the position of the antenna. Use the arctangent function (arctan) to calculate the angle; θ = atan2(dy, dx), where θ is the angle from the antenna to the target track, usually in radians and can be converted to degrees. Determine the track angle change information according to the angle from the antenna to the target track.

[0050] S130. Determine the adjustment angle of the target directional antenna according to the track angle change information and the initial alignment angle.

[0051] The track angle change information is the angle change information between the current running track of the target train and the initial running track. Convert both the track change information and the initial alignment angle to the same coordinate system, and then determine the adjustment angle according to the track change information.

[0052] Exemplarily, since the initial alignment angle is determined according to the direction of the initial running track at the initial moment, the reverse angle of the track angle change information is the adjustment angle of the target directional antenna. For example, if the track angle change information is a change from the due north direction to 30 degrees west of due west in the world coordinate system, the adjustment angle of the target directional antenna is an angle adjustment of 30 degrees towards the due north direction.

[0053] S140. Generate a direction adjustment information control command according to the adjustment angle, and send the direction adjustment information control command to the servo motor corresponding to the target directional antenna, so that the servo motor adjusts the angle of the target directional antenna according to the direction adjustment information control command to restore to the initial alignment angle.

[0054] According to the calculated adjustment angle, the antenna adjustment mechanism is controlled by a servo motor to direct the antenna towards the target direction, i.e., the initial alignment angle. Exemplarily, if the antenna needs to rotate on multiple axes (such as horizontally and vertically), the angles in the horizontal and vertical directions need to be calculated separately.

[0055] Among them, the antenna adjustment mechanism can be an antenna rotating shaft, a mechanical device connecting the antenna and the support structure, allowing the antenna to adjust its angle within a certain range. This adjustment can be horizontal (azimuth angle adjustment) or vertical (elevation angle adjustment) so that the antenna can be optimally positioned for a specific signal source or coverage area.

[0056] The technical solution of the embodiment of the present invention obtains the track angle change information through the recognition of the acquired driving track image, and then determines the adjustment angle of the directional antenna on the train according to the track angle change information, so as to ensure that even when the train is running on a track curve, the precise alignment between the directional antennas can still be achieved, improving the communication quality between trains on the same track through the directional antennas, and the adjustment method determined through the image recognition result is simple and the adjustment accuracy is relatively high.

[0057] Figure 3 It is a flowchart of another adjustment method for the directional antenna on a railway train provided by the embodiment of the present invention. This embodiment further refines the steps after the servo motor adjusts the angle of the target directional antenna according to the direction adjustment information control instruction in the above embodiment.

[0058] Based on determining the preliminary adjustment angle according to the track angle change information in the above embodiment and preliminarily adjusting the angle of the target directional antenna according to the preliminary adjustment angle, the adjustment method of the embodiment of the present invention is adopted for further adjustment to improve the communication quality between the directional antennas.

[0059] As Figure 3 shown, the method includes:

[0060] S210. Generate a plurality of candidate direction adjustment information control instructions based on a preset angle adjustment range and a single adjustment step size.

[0061] Among them, each candidate direction adjustment information control instruction corresponds to a candidate adjustment angle.

[0062] Among them, the preset angle adjustment range is determined according to the current angle. For example, with the current angle as the center, a certain angle range is adjusted in multiple preset directions around it. Among them, the preset direction and the angle range can be adjusted according to the actual situation and are not limited here. The single adjustment step size refers to the adjustment angle of the target directional antenna each time. For example, it can be determined according to the minimum adjustment angle of the servo motor.

[0063] S220. Send multiple candidate direction adjustment information control instructions to the servo motor corresponding to the target directional antenna, so that the servo motor continuously adjusts the angle of the target directional antenna according to the multiple candidate direction adjustment information control instructions, and determines the candidate communication quality parameters corresponding to each candidate adjustment angle during the continuous adjustment process.

[0064] According to the calculated candidate direction adjustment information control instructions corresponding to multiple candidate adjustment angles, control the antenna adjustment mechanism to sequentially direct the antenna towards the corresponding candidate adjustment angles through the servo motor, and determine the candidate communication instruction parameters corresponding to the candidate adjustment angle when the adjustment at each candidate adjustment angle is completed. Exemplarily, use a wireless communication module (such as Wi-Fi, LTE, LoRa, etc.) and the antenna to measure the signal strength (usually in RSSI, i.e., Received Signal Strength Indication as the unit) to determine the values at different candidate adjustment angles as the candidate communication quality parameters. Record the signal strength data at each candidate adjustment angle, and an antenna rotation device can be used to measure at a preset angle step (for example, every 5 degrees).

[0065] In a feasible embodiment, determining the candidate communication quality parameters corresponding to each candidate adjustment angle during the continuous adjustment process includes:

[0066] After the servo motor adjusts the target directional antenna to each candidate adjustment angle, control the target directional antenna to send a signal to the matching directional antenna on the reference train, and receive the feedback signal of the matching directional antenna;

[0067] Determine the candidate communication quality parameters according to the sent signal and the feedback signal; wherein, the candidate communication quality parameters include at least one of the following: the RSCP signal strength of the wireless signal and the wireless communication network signal.

[0068] Evaluate the current signal quality according to the signal sent by the wireless communication module and the received feedback signal, and record the signal strength at different candidate adjustment angles as the candidate communication quality parameters corresponding to the candidate adjustment angle.

[0069] Exemplarily, judge the quality of the wireless communication according to the RSCP signal strength of the wireless signal received by the target train and wireless communication network signals such as SNR as the candidate communication quality parameters.

[0070] S230. Determine the target adjustment angle according to the candidate communication quality parameters corresponding to each candidate adjustment angle.

[0071] Establish the relationship between the signal quality and the antenna angle according to the candidate communication quality parameters corresponding to each candidate adjustment angle, and determine the target adjustment angle based on this relationship to achieve the best signal quality at the target adjustment angle.

[0072] In a feasible embodiment, S230 includes:

[0073] Establish a relationship model between the communication quality parameter and the adjustment angle according to the candidate communication quality parameter corresponding to each candidate adjustment angle.

[0074] Determine the target adjustment angle corresponding to the maximum communication quality parameter according to the relationship model.

[0075] Use regression analysis or interpolation method to establish a mathematical model between the communication quality parameter and the adjustment angle.

[0076] Exemplarily, use a chart tool (such as Matplotlib, Excel, etc.) to draw a relationship chart between the candidate adjustment angle and the candidate communication quality parameter, and determine the relationship type between the communication quality parameter and the adjustment angle according to the relationship chart, including linear relationship and non-linear relationship. Different relationship types adopt different models. If the communication quality parameter and the adjustment angle show a linear relationship, a linear regression model is adopted; if the communication quality parameter and the adjustment angle show a non-linear relationship, a polynomial regression model is adopted.

[0077] According to the obtained relationship model, calculate the communication quality parameters at different adjustment angles, and find the angle with the strongest communication quality parameter (such as signal strength RSSI), which is the target adjustment angle.

[0078] In a feasible embodiment, S230 includes:

[0079] Sort the candidate adjustment angles in descending order according to the candidate communication quality parameters.

[0080] Determine the candidate adjustment angle ranked first as the target adjustment angle.

[0081] Exemplarily, use a chart tool (such as Matplotlib, Excel, etc.) to draw a relationship chart between the candidate adjustment angle and the candidate communication quality parameter, such as drawing a polar coordinate chart or a scatter plot, so as to intuitively understand the change of the candidate communication quality parameter with the candidate adjustment angle, and then determine the target adjustment angle from the candidate adjustment angles.

[0082] Exemplarily, set a signal strength threshold. Only when the signal strength corresponding to the candidate adjustment angle exceeds this signal strength threshold, is this angle determined as the effective target adjustment angle; if the signal strength corresponding to the currently ranked first candidate adjustment angle is less than this signal strength threshold, then this candidate adjustment angle is determined as an invalid target adjustment angle, and the number of candidate adjustment angles is increased until an effective target adjustment angle is determined.

[0083] S240. Determine the final target direction adjustment information control instruction according to the target adjustment angle, and send the target direction adjustment information control instruction to the servo motor corresponding to the target directional antenna, so that the servo motor adjusts the angle of the target directional antenna to the target adjustment angle according to the target direction adjustment information control instruction.

[0084] In the embodiment of the present invention, the track image is collected by a camera to determine the orientation information of the target train; according to the orientation information of the train, calculate the current included angle between the current orientation of the directional antenna and the orientation of the train; and then determine the preliminary adjustment angle of the target directional antenna according to the current included angle; provide the direction information control instruction corresponding to the preliminary adjustment angle to the servo motor; the servo motor drives the antenna to be preliminarily adjusted to the specified angle according to the direction information control instruction.

[0085] Based on the real-time signal strength feedback, further dynamically adjust the antenna direction at the current angle. Specifically, according to the RSCP signal strength of the wireless signal received by the train and wireless communication network signals such as SNR, judge the quality of wireless communication at the current angle; after each measurement of the signal strength, adjust the antenna towards the optimal angle direction, for example, adjust 5 degrees each time until the optimal signal strength is found.

[0086] If the train does not receive any wireless communication signals, the orientation of the antenna is determined according to the preliminary adjustment angle.

[0087] In the embodiment of the present invention, on the basis of the preliminary adjustment of the directional antenna according to the track angle change information, further adjust the angle of the directional antenna according to the communication instruction, improve the angle adjustment accuracy of the directional antenna, and ensure the communication quality between trains on the same track.
