[0024] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] The current railway contact network environmental adaptability test mainly adopts the following methods: In-laboratory testing: static testing of a single environmental parameter (such as temperature and humidity) in a controlled room; Natural condition testing: Testing is conducted on operating lines under actual weather conditions, which is long and uncontrollable. Local simulation test: Using a small environmental chamber to simulate the sample in a limited way cannot cover complex composite climate scenarios; Therefore, the existing testing scheme has the following deficiencies: 1) Uncontrollable environmental factors: It is impossible to simulate the controllable combination of multiple environmental factors such as wind, rain, fog, and light; 2) Poor repeatability: Test results are limited by natural conditions, and it is difficult to reproduce the same environmental parameters; 3) Low control accuracy: The environmental parameter adjustment error is large (more than ±15%), which cannot meet the requirements of high-precision testing; 4) Insufficient automation: Test data collection has a low degree of automation, data collection relies on manual operations, fault detection efficiency is low, and there is a lack of intelligent testing logic; 5) Unable to simulate the comprehensive environmental impact under complex working conditions.

[0026] Therefore, the present invention provides a railway contact network simulation test system and method to solve the above-mentioned deficiencies.

[0027] Figure 1 FIG. 1 is a schematic diagram of a railway contact network simulation test system according to an exemplary embodiment. Figure 1 As shown, in an exemplary embodiment, the simulation test system for a railway contact network includes: A climate simulation module 110 is used to simulate various climate environments; The data acquisition module 120 is used to collect test data of the railway contact network in each of the climate environments; The test analysis module 130 is used to perform test analysis on the railway contact network based on the test data.

[0028] In an embodiment of the present invention, the railway catenary is an overhead transmission system that provides electric energy to electric locomotives or EMUs. It is usually erected above the railway tracks and contacts the current collecting device on the top of the train through the pantograph to continuously transmit electric energy to the train drive system. It is the core infrastructure of electrified railways and directly affects the train's operating speed, safety and power supply stability.

[0029] The climate simulation module simulates various climate environments, enabling controlled combinations of wind, rain, fog, light, and other environmental factors. This module allows for consistent environmental parameters and simulates complex environments under complex working conditions, avoiding the constraints of natural conditions. The data acquisition module collects test data from the railway catenary in various climate environments, automating the collection of test data. The test analysis module automatically analyzes the railway catenary based on this test data, improving test and analysis efficiency.

[0030] In an exemplary embodiment of the present invention, the climate simulation module includes multiple climate simulation sub-modules. The climate simulation module adopts a distributed control architecture and controls each of the climate simulation sub-modules through an independent programmable logic controller to enable each of the climate simulation sub-modules to simulate the corresponding climate environment.

[0031] In an embodiment of the present invention, the climate simulation module includes multiple climate simulation sub-modules, which simulate wind, rain, fog, light, ice and snow, and dust respectively. The climate simulation sub-module can simulate one climate environment alone, or multiple climate simulation sub-modules can work together to form a composite climate environment, supporting more than 10 composite climate environment simulations, such as heavy rain, dense fog, sunny weather, etc.

[0032] Each climate simulation submodule can realize different degrees of climate environment. Specifically, the climate simulation submodule for simulating wind environment realizes wind simulation from level 1 to level 5; the climate simulation submodule for simulating rain environment realizes simulation of light rain, moderate rain, heavy rain, rainstorm, heavy rainstorm and extremely heavy rainstorm; the climate simulation submodule for simulating fog environment realizes simulation of fog, heavy fog, dense fog and extremely dense fog; the climate simulation submodule for simulating light environment realizes simulation from level 1 to level 4; the climate simulation submodule for simulating ice and snow environment realizes simulation of temperature range from -30℃ to 0℃; the climate simulation submodule for simulating sand and dust environment realizes simulation of particle concentration from 0 to 5g / m³.

[0033] In this embodiment of the present invention, the climate simulation submodule for simulating the wind environment is equipped with a matrix of six fan groups, with wind speed adjusted by a frequency converter (0-10.5m / s). The climate simulation submodule for simulating the rain environment performs artificial rainfall, with rainfall intensity adjusted by a flow valve (0-30mm / h). The climate simulation submodule for simulating the fog environment uses a high-pressure atomization integrated machine equipped with 90 nozzles, covering the atomization pipeline with a spacing of 50cm. The climate simulation submodule for simulating the light environment uses a spectrum-adjustable LED matrix to simulate different light intensities (10-16klux).

[0034] like Figure 2As shown, the climate simulation module utilizes a distributed control architecture, with independent programmable logic controllers (PLCs) providing closed-loop control of each climate simulation submodule. This architecture reads the current climate parameters of each climate simulation module in real time, compares them with the test parameters set for the test task, and automatically adjusts the current climate parameters based on the comparison results, achieving an accuracy of ±5%. This closed-loop control is achieved through automatic adjustment through detection feedback comparison. This distributed control architecture is implemented using protocols such as Modbus RTU, TCP, HTTP, PROFIBUS DP, CANopen, and wireless IoT (LoRaWAN).

[0035] In an exemplary embodiment of the present invention, the test and analysis module is configured to determine a fault type of the railway contact network based on the test data, and perform test and analysis on the railway contact network according to the fault type.

[0036] In an embodiment of the present invention, by integrating test data collected by multiple acquisition devices, it is possible to test various types of faults, including bolts within flexible suspension tunnels, pull-out values within flexible suspension tunnels, suspension strings within flexible suspension tunnels, bolts outside flexible suspension tunnels, pull-out values outside flexible suspension tunnels, suspension strings outside flexible suspension tunnels, bolts at rigid suspension stations, bolts between rigid suspension sections, insulators at rigid suspension stations, and insulators between rigid suspension sections. If the test data is collected by a salt density tester, the corresponding fault type is determined by whether the salt density on the surface of a rigid suspension station insulator or a rigid suspension section insulator exceeds a salt density threshold. The specific fault type is further determined based on the location where the salt density tester collected the data. After determining the fault type of the railway contact network based on the test data, the railway contact network is tested according to the fault type.

[0037] In an exemplary embodiment of the present invention, the data acquisition module includes at least one acquisition device selected from the group consisting of a test sensor, a laser measuring instrument, a camera module, a laser rangefinder, a salt density tester, a torque standard, and a level.

[0038] In an embodiment of the present invention, the railway contact network may be tested using test data collected by a single collection device, or may be tested based on test data collected by multiple collection devices, as shown in Table 1 below: Table 1

[0039] In the embodiments of the present invention, the aforementioned acquisition devices include an acceleration sensor for acquiring acceleration data of the object being measured; a laser measuring instrument for acquiring three-dimensional surface data of the object being measured using laser technology; a camera module for acquiring image data from the railway overhead line; a laser rangefinder for measuring the distance between two objects; a torque standard for calibrating, measuring, or verifying torque; and a timer for measuring the acquisition time of the aforementioned acquisition devices.

[0040] As shown in Table 1 above, in the scenario of image detection and geometric parameter detection and evaluation, the inspection vehicle is equipped with acquisition equipment such as a camera module, a laser measuring instrument, and a laser rangefinder. The inspection vehicle moves to the object to be measured, and the acquisition equipment accordingly collects the corresponding test data, and then tests are performed based on the collected test data. For example, when testing a bolt, the camera module captures the image of the bolt, and the distance between the bolt and the nut is calculated based on the captured image. The distance between the bolt and the nut is then measured using a laser rangefinder, and the two distances are compared with the standard distance between the bolt and the nut. If both distances are less than the standard distance, the adjustment distance that needs to be tightened for the bolt is calculated, and the corresponding test analysis results are generated based on the adjustment distance. The bolt is then adjusted based on the test analysis results.

[0041] In another embodiment of the present invention, the data acquisition module further includes an integrated infrared thermal imaging device (temperature resolution 0.1°C), an acoustic detection device (frequency range 20~40kHz), and AI visual recognition.

[0042] In the embodiment of the present invention, the data acquisition module supports RS485 / RS232 interface, can connect up to 254 acquisition devices, and has a data acquisition interval of 60s to 10min.

[0043] In an exemplary embodiment of the present invention, the railway contact network simulation test system further includes an adjustment module; The adjustment module is used to adjust the railway contact network according to the test analysis results output by the test analysis module.

[0044] In the embodiment of the present invention, after the test analysis module tests the railway contact network, a corresponding test analysis result is obtained. When the test analysis result indicates that the railway contact network needs to be adjusted, the adjustment module performs the adjustment.

[0045] In an exemplary embodiment of the present invention, the adjustment module includes an adjustment robot; The adjustment robot is used to adjust the wire pull-out value or the adjustable dropper length in the railway contact network, tighten the bolts in the railway contact network, or clean the insulators in the railway contact network according to the test analysis results.

[0046] In the embodiment of the present invention, the adjustment module includes an adjustment robot. The adjustment module drives the adjustment robot to adjust the railway contact network according to the test analysis results. The operation indicators of the adjustment robot are shown in Table 2 below: Table 2

[0047] Figure 3 FIG. 1 is a flow chart of a simulation test method for a railway contact network according to an exemplary embodiment. Figure 3 As shown, in an exemplary embodiment, the simulation test method for a railway contact network includes steps 310 to 330, which are described in detail as follows.

[0048] Step 310: Acquire a test task and simulate a corresponding climate environment according to the test task.

[0049] In the embodiment of the present invention, Figure 4 As shown, sensors, camera modules, and other acquisition devices include built-in 5G network cards, which upload collected test data directly to the multi-parameter terminal perception device platform. A Wi-Fi router provides wireless access for perception devices that support wireless data transmission. The ground system accesses the wide area network (WAN) via wired broadband and Wi-Fi router clients connecting to nearby wireless networks. The cloud-edge-end collaborative information platform, digital integrated test platform, and multi-parameter terminal perception device platform are deployed on cloud servers and communicate via the HTTP protocol.

[0050] The collected test data is forwarded through a router that supports network security functions such as firewalls to achieve secure data transmission in the wide area network. The router and switch are connected by network cables to build a private local area network. The climate simulation module and its simulation control terminal are connected to the core switch via wired means, allowing data to be transmitted between the system software and the acquisition device hardware, and providing in-vehicle WIFI to enable other terminal devices to connect wirelessly to the local area network.

[0051] Create a test task, including the time, location, and scope of the operation. Send the created test task to the cloud-edge collaborative information platform. The test task contains all the information required to submit the operation plan to the cloud-edge collaborative information platform. This means that a work plan will be created within the cloud-edge collaborative information platform. Control the corresponding climate simulation submodule to simulate the corresponding climate environment based on the test task.

[0052] Step 320: collecting test data of the railway contact network in the climate environment.

[0053] In the embodiment of the present invention, after the climate environment simulation is completed, the test is started, and at the same time, a command to execute the operation is issued to the train group, and operations such as timing and video monitoring are started to collect test data of the railway contact network in the climate environment.

[0054] Step 330: Test and analyze the railway contact network based on the test data.

[0055] In the embodiment of the present invention, the railway contact network is tested based on the test data, and at the same time, the current test stage and progress are displayed on the simulation test system of the railway contact network.

[0056] In an exemplary embodiment of the present invention, the testing and analyzing the railway contact network based on the test data includes: determining a fault type of the railway contact network based on the test data; The railway contact network is tested and analyzed according to the fault type.

[0057] In an embodiment of the present invention, the test data collected by multiple acquisition devices is integrated to test the fault types of bolts in a flexible suspension tunnel, pull-out values in a flexible suspension tunnel, hanging strings in a flexible suspension tunnel, bolts outside a flexible suspension tunnel, pull-out values outside a flexible suspension tunnel, hanging strings outside a flexible suspension tunnel, bolts at a rigid suspension station, bolts between rigid suspension sections, insulators at a rigid suspension station, and insulators between rigid suspension sections. If the test data is collected by a salt density tester, the corresponding fault type is whether the salt density on the surface of a rigid suspension station insulator or a rigid suspension section insulator exceeds a salt density threshold. The specific fault type is further determined based on the location where the data was collected by the salt density tester. After determining the fault type of the railway contact network based on the test data, the railway contact network is tested according to the fault type.

[0058] In an exemplary embodiment of the present invention, after testing and analyzing the railway contact network based on the test data, the method further includes: The railway contact network is adjusted according to the test analysis results of the railway contact network.

[0059] In an embodiment of the present invention, after testing the railway contact network, corresponding test analysis results are obtained. When the test analysis results indicate that the railway contact network needs to be adjusted, the railway contact network is adjusted. An adjustment robot is provided, and the adjustment robot is driven to adjust the railway contact network based on the test analysis results. The specific adjustments are shown in Table 2 above and are not further described here.

[0060] In an exemplary embodiment of the present invention, the testing and analyzing the railway contact network based on the test data includes: Based on the test data, the droppers, conductor pull-out values, bolts and insulators of the railway contact network are tested and analyzed.

[0061] In an embodiment of the present invention, various test data are collected by collecting device data transmission, manual input, operating system basic data, etc., and tests are performed on aspects such as suspension string replacement and adjustment, image detection and geometric parameter detection, pull-out value adjustment, insulator cleaning, and high-clearance maintenance. During the test, evaluation indicators of various aspects are calculated, and a weighted sum calculation is performed on each evaluation indicator to obtain the final test analysis result.

[0062] In an embodiment of the present invention, a test scenario instruction is sent to the cloud-edge collaborative information platform. For example, the climate environment parameters are set to a wind speed of 8.3m / s and a rainfall intensity of 25mm / h. The climate simulation submodule that simulates the wind and rain environments synchronizes the climate environment parameters to complete the climate environment establishment and signal feedback. Multi-sensor fault monitoring is initiated, and test data is continuously collected for 10 minutes. The test data is transmitted back to the test analysis module in real time. When a device failure or offline is detected, the platform activates the alarm function to issue an alarm.
