Therefore, they have no substantial technical significance. Any modifications to the structure, changes in scale, or adjustments to size, without affecting the effects and objectives achieved by the invention, should still fall within the scope of the technical content disclosed in the invention.

[0040] Given the isolated nature of existing turnout monitoring systems, and the lack of systematic and comprehensive correlation analysis of data from indoor turnout circuit monitoring, outdoor turnout gap monitoring, and laser ranging monitoring, the turnout fault detection system suffers from inaccuracy and low efficiency.

[0041] refer to Figure 1 As shown in the figure, this embodiment provides a turnout comprehensive monitoring and analysis system, including: a turnout comprehensive monitoring intelligent diagnosis module and a turnout comprehensive monitoring analysis early warning module.

[0042] The integrated intelligent diagnostic module for turnout monitoring includes an interactively linked indoor fault diagnosis unit and an outdoor fault diagnosis unit. The indoor fault diagnosis unit includes a turnout circuit acquisition device, which collects the indicating voltage of the indoor indicator circuit and the operating voltage of the indoor operating circuit, while simultaneously monitoring the operating current curve and power curve during the turnout's operation. The outdoor fault diagnosis unit includes a turnout gap monitoring device and an outdoor laser ranging monitoring device. The turnout gap monitoring device monitors the size of the gap in the turnout's switch machine using image recognition methods and can intelligently provide early warnings for maintenance. By measuring the left-right swaying of the gap during train passage, the tightness of the turnout's connection can be analyzed, and combined with outdoor turnout connection data collection, more accurate analysis results are provided. This is used to provide early warnings before the switch machine shows signs of loosening. The outdoor laser ranging monitoring device is integrated with the turnout gap monitoring device to collect outdoor turnout data and analyze the turnout's connection status in conjunction with the size of the switch machine's gap.

[0043] refer to Figure 4 As shown, the turnout circuit acquisition device collects the turnout indication voltage and operating voltage, and simultaneously supports the monitoring of the operating current curve and power curve during turnout operation. The turnout power acquisition module and current acquisition module are installed on the back of the turnout assembly for easy access. Voltage acquisition is performed on the front terminals of the phase loss protector (DBQ), and current acquisition is performed by placing the cable from the phase loss protector (DBQ) to the subsequent circuit through the current sensor core. Turnout operation judgment uses a switch quantity module to acquire the 1DQJ / 1DQJF relay contacts. For the turnout indication voltage and operating voltage acquisition on the distribution panel, AC turnout indication voltage is sampled at constant values ​​X2 and X4, and at inverted values ​​X3 and X5; DC turnout indication voltage is sampled at constant values ​​X1 and X3, and at inverted values ​​X2 and X3; AC turnout operating voltage is sampled at constant values ​​X1, X2, and X5, and at inverted values ​​X1, X3, and X4; DC turnout operating voltage is sampled at constant values ​​X4 and X1, and at inverted values ​​X4 and X2.

[0044] The turnout integrated monitoring, analysis and early warning module performs comprehensive analysis on the data collected by the indoor fault unit and the outdoor fault diagnosis unit respectively, in order to provide early warning analysis and location of turnout faults.

[0045] The turnout circuit acquisition device includes: a current acquisition module for acquiring the operating current during the turnout's operation; and a turnout power acquisition module connected to the current acquisition module for acquiring the power during the turnout's operation. The current acquisition module includes a current sensor that acquires the operating current at the cable from the phase-loss protector to the subsequent circuit. The turnout circuit acquisition device also includes a switching quantity module that acquires data from the relay nodes in the operating circuit to determine the turnout's operation.

[0046] The turnout integrated monitoring and analysis system is based on an indoor PLC host and an intelligent operation and maintenance system station. The outdoor laser ranging monitor is connected to the PLC, and transmits the outdoor turnout data to the PLC host. The PLC host analyzes and processes the outdoor turnout data to obtain processed data, which is then transmitted to the intelligent operation and maintenance system station. The outdoor laser ranging monitor and the PLC host are connected via two sets of shielded cables, one of which is a spare connection cable.

[0047] The outdoor turnout data includes any one or any combination of the following: the creep distance of the switch rail or the stock rail, the turnout contact distance, and the stock rail gauge.

[0048] The outdoor laser ranging monitoring includes a laser displacement sensor, which is used to measure the outdoor turnout data. In this embodiment, the laser displacement sensor measures the creep distance of the switch rail or stock rail, the turnout contact distance, and the stock rail gauge.

[0049] The outdoor laser ranging monitoring system is also used to monitor turnout switching and train passage processes. Specifically, the monitoring of turnout switching involves: based on the displacement data measured by the laser displacement sensor, the outdoor laser ranging monitoring system obtains curve data of the switching state, and uploads this curve data to the PLC host to monitor the turnout switching. The monitoring of the train passage process involves: after receiving a train passage command from the host computer, the laser displacement sensor periodically records the data of the current train passage process, and the outdoor laser ranging monitoring system uploads this data to the PLC host to monitor the train passage process.

[0050] Outdoor turnout contact and track gauge monitoring employs laser ranging, using laser displacement sensors to measure the creep distance of the switch rail / stock rail, turnout contact, and stock rail gauge. The outdoor laser ranging monitoring transmits the collected data back to the indoor PLC host via power line carrier wave. The PLC host then aggregates and processes the data before sending it to the intelligent operation and maintenance system station. Simultaneously, it monitors turnout switching and train passage processes.

[0051] refer to Figure 5 As shown, the switching monitoring is specifically as follows: When the switch machine moves the turnout, the laser displacement sensor used to monitor the switch rail will detect the displacement of the switch rail. The acquisition unit determines that the current turnout has started to move based on the displacement data of the laser displacement sensor, and then enters the switching state. The turnout switching time is <20s, the data acquisition frequency is 20Hz, and during the entire switching process, the acquisition unit records the data transmitted back by each laser displacement sensor once every 50ms. The switching state ends when the laser displacement sensor detects that the turnout is no longer moving. After the switching is completed, the acquisition unit uploads the curve data to the PLC host.

[0052] Vehicle passage monitoring is specifically as follows: When the PLC host receives the vehicle passage command from the host computer, it determines that a vehicle is passing through. Then, it records the data transmitted back by each laser displacement sensor every 20ms. After recording data for 10 seconds, the data acquisition unit uploads the curve data to the PLC host.

[0053] The outdoor laser ranging monitoring is also used to monitor the contact between the switch rails and the gauge of the main track (reference). Figure 6 Position 1 in the monitoring system), monitoring the basic track crawl distance (reference) Figure 6 Position 2 in the middle), monitoring switch rail displacement (reference) Figure 6 Position 3 in the middle) and monitoring the displacement of the basic track (reference) Figure 6 (Position 4 in the middle).

[0054] Monitor the tightness of the switch rails and the gauge of the main rail (reference) Figure 6 Position 1 in the diagram is as follows: After the laser displacement sensor is placed on the shim, it is fixed to the concrete sleeper with expansion bolts. The vertical installation position of the switch rail close-fitting sensor is about 400mm (as close as possible to the base rail mounting block), and the horizontal installation position is about 45mm. The vertical installation position of the base rail gauge sensor is as close as possible to the base rail mounting block, and the horizontal installation position is centered longitudinally on the concrete sleeper.

[0055] Monitor the basic track crawl distance (reference) Figure 6 Position 2 in the diagram is specifically located 160mm from the vertical plane of the switch machine mounting bracket, near the sleeper. After placing a 60mm high shim on the pad, use expansion screws to fix the laser displacement sensor to the cement base.

[0056] Monitoring switch rail displacement (reference) Figure 6 Position 3 in the middle is as follows: at the secondary traction point, at the position where the gauge of the switch rail is measured, find a suitable position (centering is preferred) near the mounting pad of the main rail, place a 100mm high pad block on it, and then fix it to the cement base with expansion screws.

[0057] Monitoring the displacement of the basic track (reference) Figure 6 Position 4 in the diagram is as follows: Install a laser displacement sensor between two sleepers next to the track, place a 100mm high shim on top, and then fix the laser displacement sensor to the cement base with expansion screws.

[0058] The outdoor laser ranging monitoring system is mounted on a bracket located outside the train track. The bracket also houses a temperature sensor and a humidity sensor, both connected to the outdoor laser ranging monitoring system. The temperature and humidity sensors are used to monitor the temperature and humidity data at the outdoor laser ranging monitoring location in real time and transmit these data to the system.

[0059] refer to Figure 7 As shown, the installation location of the outdoor laser ranging monitoring unit in this embodiment should be determined according to the site conditions, but the principle is to install it at a straight distance of 1m from the rail and fix it to the horizontal ground with a dedicated mounting bracket. The temperature sensor and humidity sensor are both installed next to the outdoor laser ranging monitoring unit and fixed together with the outdoor laser ranging monitoring mounting bracket. The data acquisition unit is connected to the PLC main unit via two sets of two-core shielded cables (one set is a spare), and the maximum length should not exceed 1km; the laser displacement sensor, temperature sensor, and humidity sensor are each connected to the data acquisition unit via two-core shielded cables; the connection between the laser displacement sensor and the data acquisition unit should not exceed 6m, and both ends of the shielded cable use waterproof, shockproof, and impact-resistant metal connectors.

[0060] refer to Figure 2 As shown, the turnout integrated monitoring and intelligent diagnostic module includes an indoor fault diagnosis module and an outdoor fault diagnosis module. The turnout integrated monitoring and intelligent diagnostic module categorizes turnout anomalies into: turnout operation not activated, turnout operation not in place, turnout switching in place with no indication, and turnout not activated with no indication.

[0061] a. Turnout operation not activated: Indoor monitoring section: 1DQJ excitation circuit fault, 1DQJ unable to self-close, three-phase operating power output is zero, single-phase current is zero in three-phase current; Outdoor monitoring section: X1 / X2 / X3 / X4 / X5 open circuit.

[0062] b. Turnout operation not in place: Specifically, for indoor monitoring: the operation curve has no small step and all three phases return to zero simultaneously (1DQJ self-closing circuit fault); the operation curve has no small step and a single phase returns to zero prematurely (indoor X1 / X2 / X3 / X4 / X5 open circuit). For outdoor monitoring: specifically: jamming during unlocking or switching; jamming during switching or locking; motor idling and switch machine malfunction; and outdoor X1 / X2 / X3 / X4 / X5 open circuit.

[0063] c. No indication after turnout is switched to the correct position: For indoor monitoring, this is specifically: fault in the fixed / reverse position indication circuit, or excessively long step on the action curve (DBQ fault); For outdoor monitoring, this is specifically: fault in the fixed / reverse position indication circuit, or no step on the action curve.

[0064] d. Turnout non-operation indication: Indoor monitoring section specifically: fixed / reverse position indication circuit fault, indication coil branch open circuit or resistor short circuit; Outdoor monitoring section specifically: fixed / reverse position indication circuit fault, outdoor diode circuit open circuit, outdoor diode breakdown.

[0065] The specific warning content of the turnout integrated monitoring, analysis and early warning module includes: warning of faults in the indoor display circuit, warning of faults in the indoor operating circuit, warning of faults in the switch machine and warning of faults in the turnout.

[0066] refer to Figure 3 As shown, the turnout integrated monitoring, analysis, and early warning module includes an indoor analysis and early warning module, a curve analysis and early warning module, and an outdoor analysis and early warning module. The following analysis examines the causes of failures in each module's early warning system.

[0067] 1. Indoor early warning analysis: The causes of the fault include: unbalanced three-phase current; poor contact due to fluctuations in three-phase current; sudden change in current when the turnout rotates, which may be due to poor contact of the circuit contacts; sudden change in current when the turnout rotates, which may be due to cross-connection or grounding; short circuit of phases BC after rotation locking.

[0068] 2. Curve analysis and early warning: The causes of the fault include: too short rotation time; too long total curve time; voltage exceeding the limit for fixed / reverse AC / DC; voltage fluctuation abnormal for fixed / reverse AC / DC; voltage exceeding the limit for AB / BC / AC lines.

[0069] 3. Outdoor early warning analysis: The causes of failure include: high resistance during unlocking or switching; high resistance during switching or locking; excessive rotation time, which may be due to insufficient lubrication of the slide plate or low friction; large deviation of small step value after switching to position, which may be due to malfunction of the rectifier stack; poor contact of the automatic switch contacts; 2mm / 4mm turnout tightness warning; frame displacement warning.

[0070] In summary, this embodiment proposes a comprehensive turnout monitoring and analysis system. Through multi-directional online monitoring and comprehensive analysis of indoor and outdoor data, it automates turnout inspection, patrol, and maintenance, improving the level and efficiency of urban rail transit operation and maintenance, providing a guarantee for safe operation, and solving the problems of the singularity and isolation of existing turnout monitoring systems' indoor and outdoor turnout monitoring. By designing a turnout comprehensive monitoring intelligent diagnosis module and a turnout comprehensive monitoring analysis early warning module, the turnout fault diagnosis and early warning analysis and location are more accurate. Based on laser ranging technology on a laser displacement sensor, real-time and dynamic measurements are realized to analyze whether the turnout's positional and reverse transitions are smooth, the track gauge during train passage, and the close-fitting change curve. By integrating and mining different characteristic data, such as the correlation analysis between operating voltage and gap value, and gap value and close-fitting value, the comprehensive diagnosis and analysis of the turnout system becomes more intelligent.
