Description

Technical Field

[0001] This invention relates to the field of wireless network deployment technology, and more specifically to a wireless network deployment method for signal testing of long-distance transmission and inspection systems. Background Technology

[0002] Currently, long-distance conveying systems are widely used in complex cross-regional material handling scenarios across multiple industries due to their advantages such as large capacity, long distance, low energy consumption, and continuous operation. Real-time transmission of inspection data is crucial during long-distance conveying inspections. A well-planned wireless network can promptly locate potential hazards and reduce safety risks during long-distance conveying. Therefore, how to rationally deploy a wireless network for long-distance conveying inspections has become an urgent problem to be solved. Summary of the Invention

[0003] This invention provides a wireless network deployment method for signal testing of long-distance transmission inspection systems, in order to solve the problem of how to reasonably deploy wireless networks for long-distance transmission inspection.

[0004] In a first aspect, the present invention provides a wireless network deployment method for signal testing of a long-distance transmission and inspection system, the method comprising:

[0005] Obtain the plan layout of the long-distance conveyor inspection system and perform vectorization on the plan layout; Based on the vectorization results, the location of the wireless base station is determined, and a signal strength threshold is set. The control signal test vehicle executes the test task according to the preset path and collects the current signal strength; The current signal strength is compared with the signal strength threshold, and the location of the wireless base station is adjusted based on the comparison result.

[0006] This invention determines the location of wireless base stations by vectorizing the floor plan during the construction drawing stage, thereby enabling scientific placement of wireless base stations. It also sets signal strength thresholds to avoid subjectivity in signal strength determination. The signal strength collected by the signal testing vehicle along a preset path is compared with the signal strength thresholds to serve as the data basis for base station adjustments. This allows for base station optimization and adjustment during the construction drawing stage, making the base station layout more scientific and reliable, and minimizing the need for later on-site relocation and addition of base stations.

[0007] In one alternative implementation, the plan layout is vectorized, including: Identify key features in the floor plan, including long-distance transport inspection paths, sidewalks, turning points, and slope changes. Perform coordinate calibration on the floor plan.

[0008] This invention identifies key features in the floor plan to fully understand the specific scene, providing a basis for determining the location of the base station. By calibrating the coordinates of the floor plan, it facilitates subsequent coordinate association and enables accurate location tracking.

[0009] In one alternative implementation, determining the location of the wireless base station and setting a signal strength threshold includes: In response to base station location marking and base station location adjustment operations, the location of the wireless base station is determined; Generate the number of the wireless base station according to the numbering rules, and configure the type and transmission power of the wireless base station; Set the normal signal strength range and the abnormal signal strength range respectively, with the minimum value of the normal signal strength range being greater than the maximum value of the abnormal signal strength range.

[0010] This invention accurately locates the position of a wireless base station by responding to the base station location operation, ensuring that the wireless base station deployment meets the needs of the scenario, uniformly determining the wireless base station number, type, and transmission power, avoiding signal interference and other problems caused by inconsistent parameters, and ensuring the reliability of the judgment results by clearly defining the normal signal strength range and the abnormal signal strength range.

[0011] In one alternative implementation, the method further includes: An initial path is generated along the centerline of the sidewalk using a path planning algorithm; The system uses radar scanning to identify obstacles and adjusts the initial path based on the location of the obstacles to obtain a preset path.

[0012] This invention generates an initial path through a path planning algorithm, ensuring that the initial path does not deviate from the center line of the pedestrian walkway. The initial path is adjusted based on the radar scan results to avoid collision damage to the signal test vehicle and to prevent test interruptions caused by obstacles.

[0013] In one optional implementation, the current signal strength is compared with a signal strength threshold, and the location of the wireless base station is adjusted based on the comparison result, including: If the current signal strength is within the range of abnormal signal strength, it is identified as a weak signal area. The location of the wireless base station is adjusted according to the preset base station adjustment plan, which includes relocating the wireless base station and adding a new wireless base station.

[0014] This invention optimizes wireless base stations by adjusting their location, thereby minimizing on-site work required for subsequent adjustments.

[0015] In one alternative implementation, the method further includes: If the current signal strength is within the range of abnormal signal strength, an alarm message will be generated and an alarm label will be automatically marked on the floor plan.

[0016] This invention automatically marks alarm signs on the floor plan to visually reflect the location of abnormalities, making it easier for staff to quickly locate the abnormalities.

[0017] In one alternative implementation, the method further includes: Generate a wireless base station deployment report, which includes the wireless base station number, location coordinates, type, and parameters. Generate a signal quality analysis report, which includes time, region, and number of alarms.

[0018] This invention integrates core information of wireless base stations by generating wireless base station deployment reports, enabling standardized management of the entire lifecycle of wireless base stations. It also quantifies signal quality by generating signal quality analysis reports, facilitating the tracing of signal anomalies.

[0019] In a second aspect, the present invention provides a wireless network deployment device for signal testing of a long-distance transmission inspection system, the device comprising: The acquisition module is used to acquire the plan layout diagram of the long-distance conveying inspection system and perform vectorization processing on the plan layout diagram. The determination module is used to determine the location of wireless base stations based on the vectorization processing results and set the signal strength threshold; The acquisition module is used to control the signal test vehicle to perform test tasks according to a preset path and to acquire the current signal strength; The adjustment module is used to compare the current signal strength with the signal strength threshold and adjust the position of the wireless base station based on the comparison result.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0026] Currently, in the construction drawing design phase, long-distance transmission and inspection systems use a uniformly distributed approach to set up wireless base stations. If the spacing between base stations is too small, the cost is high, the construction workload is large, and the debugging workload is extensive; if the spacing is too large, the quality of wireless signal transmission cannot be guaranteed. Therefore, in the construction drawing phase, rationally and scientifically arranging the wireless network and enabling network signal testing has become an urgent problem to be solved.

[0027] The present invention provides a wireless network deployment method for signal testing of a long-distance transmission inspection system. Its hardware foundation adopts a wireless network transmission system composed of industrial-grade wireless base station equipment, high-frequency low-loss feeder, directional antenna, seamless roaming equipment, and omnidirectional antenna.

[0028] The mainstream wireless products in this wireless network transmission system use Qualcomm chips. The signal test vehicle is equipped with one or more independent RF modules that are fully compatible with IEEE 802.11a / n. Each module has a transmission rate of up to 300Mbps and adopts multi-link transmission technology to support high-speed seamless roaming between different APs (Access Points), achieving seamless switching with "0" packet loss.

[0029] Employing a smart antenna output, the 2×2300Mbps modulation is split into two 1×1150Mbps signals to extend coverage. It supports wireless multicast reception and forwarding, as well as various anti-interference strategies, and includes built-in spectrum scanning and malicious AP detection. The device features a wide operating temperature range of -40℃ to +60℃.

[0030] like Figure 1 As shown, wireless base stations are deployed along the long-distance transport inspection system to form a wireless network, such as wirelee-BC01. The inspection robot is equipped with a wireless roaming device with the same IP network segment and frequency band, and connects to the wirelee-BC01 wireless network. When the inspection robot performs inspection tasks, it collects real-time data on the status of equipment, environment, and personnel along the long-distance transport inspection system. Through the wireless communication link between the wireless roaming device and the wireless base station, and finally through the optical fiber between the wireless base stations, the collected data is uploaded in real-time to the central control room management platform.

[0031] For long-distance conveyor systems deployed in the open, when the inspection robot travels above the conveyor belt or pipe (rail-mounted, wheeled, or truss-crossing type), a wireless base station is generally set up every 300 meters. When the inspection robot travels between the upper and lower conveyor belts (rail-mounted type), a wireless base station is generally set up every 100 to 150 meters.

[0032] For long-distance conveyors arranged in a straight line within a trestle or tunnel, when the inspection robot travels above the conveyor belt or pipe (rail-mounted, wheeled, or truss-crossing type), a wireless base station is generally set up every 200 meters. When the inspection robot travels between the upper and lower conveyor belts (rail-mounted type), a wireless base station is generally set up every 100 meters.

[0033] For long-distance transport with bends or slopes in trestle bridges or tunnels, when the inspection robot travels above the belt or pipe (rail-mounted, wheeled, or truss-crossing type), a wireless base station is generally set up every 150 meters. When the inspection robot travels between the upper and lower belts (rail-mounted type), a wireless base station is generally set up every 70 to 100 meters.

[0034] According to an embodiment of the present invention, a wireless network deployment method for signal testing of a long-distance transmission inspection system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0035] This embodiment provides a wireless network deployment method for signal testing of a long-distance transmission inspection system. Figure 2 This is a flowchart of a wireless network deployment method for signal testing of a long-distance transmission inspection system according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: Obtain the plan layout of the long-distance conveying inspection system and perform vectorization processing on the plan layout.

[0036] In this embodiment of the invention, a plan layout diagram of a long-distance transport inspection system is imported, supporting formats such as DXF, DWG, PNG, and PDF. The plan layout diagram is then vectorized, converting unstructured drawings into structured vector data, providing a data foundation for the deployment of wireless base stations.

[0037] Step S202: Based on the vectorization processing results, determine the location of the wireless base station and set the signal strength threshold.

[0038] In this embodiment of the invention, the location of the wireless base station is marked based on the vectorization result of the plan layout diagram, the location of the wireless base station is determined, and a custom signal strength threshold is defined.

[0039] In step S203, the control signal test vehicle executes the test task according to the preset path and collects the current signal strength.

[0040] In this embodiment of the invention, the signal test vehicle adopts a two-wheel differential drive + auxiliary omnidirectional wheel structure, is battery powered, and its body size is adapted to the width of the sidewalks on both sides.

[0041] The signal test vehicle is configured as follows: (1) Wireless roaming equipment: equipped with wireless roaming equipment that is compatible with wireless base stations along the route. Two sets of omnidirectional high-gain antennas are installed on the top of the vehicle for wide-area signal reception. The antennas can be rotated 360° to adjust the direction. One directional antenna is configured for specific base station signal focusing test. (2) Battery: It adopts a 48V / 40Ah lithium battery pack with a range of ≥8km. It integrates a battery management system (BMS) to monitor the power and temperature in real time and provide low power alarm (threshold can be set). (3) Navigation radar: Equipped with 4 lidars (1 at each of the four corners of the chassis, with a scanning range of 0.1~10m and an angle of 360°) for environmental modeling and obstacle detection; wheel speed encoders for mileage calculation; (4) Human-computer interaction: The touch screen displays real-time signal data, walking trajectory, and equipment status. Test parameters can be manually set, and tasks can be started / stopped. (5) Main control board: adopts an industrial-grade ARM architecture processor to coordinate the work of each module (navigation control, signal acquisition, data processing), and supports local data storage and edge computing; (6) Remote control: A 2.4GHz wireless remote control is used, which allows maintenance personnel to perform forward, backward, turning, speed adjustment and emergency braking operations on the spot; (7) 4G gateway: Uses an industrial-grade 4GCat.4 module compatible with the networks of the three major operators, supports VPN encrypted transmission, realizes real-time uploading of test data to the base station deployment system in the central control room, and can receive remote control commands (such as task adjustment, firmware upgrade).

[0042] The signal test vehicle supports both autonomous navigation and remote control modes. It automatically travels along a preset path, performs test tasks, and conducts full-line wireless network signal testing. It collects real-time wireless network signal strength data, associates it with location coordinates and timestamps, and monitors the signal status as shown in the diagram. Figure 3 As shown.

[0043] In addition, it supports remote viewing of the signal test vehicle's location, status, and real-time signal curves, and allows for remote start / pause / termination of test tasks. It also supports automatic detection of sensor, battery, and communication module faults, providing alarms via touchscreen and remote system.

[0044] Step S204: Compare the current signal strength collected with the signal strength threshold, and adjust the position of the wireless base station according to the comparison result.

[0045] In this embodiment of the invention, the current signal strength collected is compared with a preset signal strength threshold to obtain a comparison result. The location of the wireless base station is adjusted according to the comparison result to optimize the wireless base station layout.

[0046] The spacing between wireless base stations varies depending on the process layout of the long-distance transport inspection system and the different models of inspection robots.

[0047] The wireless network deployment method for signal testing of long-distance transmission and inspection systems provided in this embodiment determines the location of wireless base stations by vectorizing the plan layout during the construction drawing stage, so as to scientifically deploy the wireless base stations, set the signal strength threshold, avoid the subjectivity of signal strength judgment, and compare the signal strength collected by the signal test vehicle along the preset path with the signal strength threshold as the data basis for base station adjustment. In this way, the base station optimization and adjustment can be completed during the construction drawing stage, making the base station deployment more scientific and reliable, and minimizing the need for later on-site relocation and addition of base stations.

[0048] This embodiment provides a wireless network deployment method for signal testing of a long-distance transmission inspection system, the process of which includes the following steps: Step S301: Obtain the plan layout of the long-distance conveying inspection system and perform vectorization processing on the plan layout.

[0049] Specifically, the vectorization process of the floor plan in step S301 above includes: Step S3011: Identify key features in the floor plan; Step S3012: Perform coordinate calibration on the floor plan.

[0050] In this embodiment of the invention, key features in the plan layout are identified, including features such as long-distance transport inspection paths, pedestrian walkways, turning nodes, and slope changes.

[0051] Specifically, in the plan layout, outline lines represent long-distance transport and inspection paths, dashed lines represent sidewalks, changes in path curvature represent turning nodes, and elevation markings and slope symbols represent slope changes to achieve key feature identification. This is just an example and is not intended to be a limitation.

[0052] To adapt to floor plans of different sizes and scales, the system supports drawing zoom, panning, and layer management functions. It also performs coordinate calibration on the drawings, supporting either custom coordinate system calibration or BeiDou positioning coordinate calibration. Custom coordinate system calibration converts the drawing coordinates to a custom coordinate system, while BeiDou positioning coordinate calibration converts the drawing coordinates to the BeiDou positioning coordinate system. This coordinate calibration establishes a mapping relationship between the drawing coordinates and the actual physical coordinates, eliminating drawing errors and ensuring the spatial accuracy of base station location markings.

[0053] By identifying key features in the floor plan, a comprehensive understanding of the specific scenario can be achieved, providing a basis for determining the location of the base station. By calibrating the coordinates of the floor plan, subsequent coordinate association can be facilitated, enabling accurate location tracking.

[0054] Step S302: Based on the vectorization processing results, determine the location of the wireless base station and set the signal strength threshold.

[0055] Specifically, the steps S302 above, including determining the location of the wireless base station and setting the signal strength threshold, include: Step S3021: In response to the base station location marking operation and the base station location adjustment operation, determine the location of the wireless base station; Step S3022: Generate the number of the wireless base station according to the numbering rules, and configure the type and transmission power of the wireless base station; Step S3023: Set the normal signal strength range and the abnormal signal strength range respectively.

[0056] In this embodiment of the invention, on the base station deployment software interface, staff can mark the base station locations on the walkways along both sides of the long-distance transport inspection path by clicking the mouse. In response to the staff's base station location marking operation on the base station deployment software interface, the initial location of the wireless base station is determined. In addition, staff can also adjust the base station location by dragging the mouse. In response to the staff's base station location adjustment operation on the base station deployment software interface, the location of the wireless base station is determined.

[0057] Customize the wireless base station numbering rules and generate wireless base station numbers according to the base station numbering rules. For example, the wireless base station number adopts the format of "#region code-base station identifier-serial number#scene label", such as "#16-BC01-3#stack" which represents the 16th segment, the base station identifier is BC01, the third base station, and the scene label is stack.

[0058] At the same time, parameters such as base station type and transmission power are entered. For example, base station type includes 5G base station, Wi-Fi 6 AP, etc., and the unit of transmission power is dBm (decibels milliwatts). The default transmission power of 5G base station is 25dBm, and the default transmission power of Wi-Fi 6 AP is 29dBm.

[0059] In addition, a standardized Excel import template is provided to batch import or export information such as wireless base station codes and project names, and save it to the database for easy viewing by staff.

[0060] Signal strength can be customized according to region, base station type, or test point, and is divided into normal signal strength range and abnormal signal strength range. The minimum value of the normal signal strength range is greater than the maximum value of the abnormal signal strength range. For example, the normal signal strength range is -25dBm to -64dBm, and the abnormal signal strength range is below -65dBm.

[0061] By responding to base station location operations, the location of wireless base stations can be accurately determined, ensuring that the deployment of wireless base stations meets the needs of the scenario. The number, type, and transmission power of wireless base stations are uniformly determined, avoiding signal interference and other problems caused by inconsistent parameters. By clearly defining the range of normal signal strength and the range of abnormal signal strength, the reliability of the judgment results is ensured.

[0062] In some alternative implementations, the method further includes: Step S303: Generate an initial path along the centerline of the sidewalk using a path planning algorithm; Step S304: Use radar scanning to identify obstacles, and adjust the initial path based on the location of the obstacles to obtain a preset path.

[0063] In this embodiment of the invention, an initial path is generated along the centerline of the sidewalk using a path planning algorithm, and the deviation error of the signal test vehicle is always within 10 centimeters, ensuring that the driving trajectory of the signal test vehicle covers the test range.

[0064] The initial path is locally adjusted by scanning for obstacles on the pedestrian walkway using radar. Specifically, a lidar is installed at each of the four corners of the signal test vehicle chassis to scan for obstacles such as temporary construction equipment and bridge piers on the pedestrian walkway, and the obstacles are identified through edge computing.

[0065] Based on the location of obstacles, the initial path is adjusted. If there is an obstacle on one side, the path is adjusted to bypass the obstacle on the other side. If there is an obstacle in the middle, the path is adjusted to bypass the obstacle in an "S" shape to obtain the final preset path. When an obstacle larger than or equal to 10 centimeters is encountered, the control signal test vehicle automatically stops and an alarm is triggered.

[0066] An initial path is generated using a path planning algorithm to ensure that it does not deviate from the center line of the pedestrian walkway. The initial path is then adjusted based on radar scan results to avoid collisions and damage to the signal test vehicle, and to prevent test interruptions caused by obstacles.

[0067] In step S305, the control signal test vehicle executes the test task according to the preset path and collects the current signal strength.

[0068] Please see details Figure 2 Step S203 of the illustrated embodiment will not be described again here.

[0069] Step S306: Compare the current signal strength collected with the signal strength threshold, and adjust the position of the wireless base station according to the comparison result.

[0070] Specifically, step S306 includes: Step S3061: If the current signal strength is within the range of abnormal signal strength, it is determined to be a weak signal area; Step S3062: Adjust the location of the wireless base station according to the preset base station adjustment plan.

[0071] In this embodiment of the invention, if the current signal strength is below -65dBm, i.e., within the abnormal signal strength range, the area is identified as a weak signal area. Preset base station adjustment schemes include relocating wireless base stations and adding new wireless base stations.

[0072] For example, if the signal strength is within the range of abnormal signal strength, and signal propagation is obstructed due to obstructions such as bridge piers, the location of the wireless base station will be moved to avoid the obstructions, thereby ensuring wireless signal transmission. If the existing wireless base stations cannot cover long-distance blind spots due to excessive spacing between them, new wireless base stations need to be added in the blind spot area.

[0073] By adjusting the location of wireless base stations, wireless base stations can be optimized, minimizing on-site work required for subsequent adjustments.

[0074] In some alternative implementations, the method further includes: Step S307: If the current signal strength is within the range of abnormal signal strength, an alarm message is generated and an alarm label is automatically marked on the floor plan.

[0075] In this embodiment of the invention, if the current signal strength is within the abnormal signal strength range, a dual alarm mechanism is activated to generate alarm information, including alarm time, location coordinates, current signal value, associated base station number, duration, etc. An alarm pop-up window is displayed to prompt staff to handle the anomaly promptly, and alarm record queries are supported. Simultaneously, alarm markers are indicated on the floor plan using red or other colors to visually indicate the anomaly points.

[0076] By automatically marking alarm signs on the floor plan, the abnormal locations can be visually reflected, making it easier for staff to quickly locate the abnormal locations.

[0077] In some alternative implementations, the method further includes: Step S308: Generate a wireless base station deployment report; Step S309: Generate a signal quality analysis report.

[0078] In this embodiment of the invention, a wireless base station deployment report is generated. The wireless base station deployment report includes basic information such as wireless base station number, wireless base station location coordinates, wireless base station type, and wireless base station parameters. The wireless base station deployment report integrates all information in Excel format, which facilitates quick querying, verification, and management by staff.

[0079] Generate a signal quality analysis report. The report statistically analyzes the signal strength distribution by time and region, and counts the number of alarms. The report is presented in PDF format, and the results are displayed in the form of trend charts.

[0080] Wireless base station deployment reports and signal quality analysis reports support automatic export at set times, and access can be controlled by permissions.

[0081] The wireless network deployment method for signal testing of long-distance transmission inspection systems provided in this embodiment generates a wireless base station deployment report, integrates the core information of the wireless base station, realizes standardized management of the entire life cycle of the wireless base station, and generates a signal quality analysis report to quantify signal quality and facilitate the tracing of signal anomalies.
