Technical Field

[0001] This utility model relates to the field of railway optical cable management, and in particular to an integrated device for detecting, measuring and mapping railway optical cable routes. Background Technology

[0002] In the field of railway electrical engineering, fiber optic cables serve as core infrastructure for information transmission and signal control, and their precise management and efficient maintenance are crucial for ensuring railway operational safety. However, current railway fiber optic cable management practices still face several technical challenges.

[0003] Traditional cable route maps are primarily two-dimensional diagrams, lacking the dynamic positioning and navigation capabilities of a Geographic Information System (GIS). In actual maintenance scenarios, maintenance personnel must compare the relative positions marked on the map on-site, unable to directly obtain the absolute geographic coordinates of the fault point. Especially in complex terrain or areas with overlapping cable laying, manual comparison is prone to errors, leading to prolonged fault location time. Currently, the railway fiber optic cable management field lacks integrated devices that combine detection, measurement, and mapping functions. In existing solutions, cable route detection, distance measurement, and route map drawing are typically completed step-by-step by independent equipment or systems, resulting in fragmented workflows, time-consuming fault location, and consequently impacting the efficiency of emergency response to cable faults.

[0004] Therefore, a new device is urgently needed. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated device for detecting, measuring, and mapping railway optical cable routes, which solves the problems in the existing technology, such as insufficient positioning accuracy due to outdated technical data, low efficiency of manual detection, lack of dynamic navigation function in the route map, and slow location of cable fault points and limited emergency response efficiency due to poor system integration.

[0006] To achieve the above objectives, this utility model provides an integrated device for detecting, measuring, and mapping railway optical cable routes. The device structure includes a receiving module, a detection module, a positioning module, a mapping module, and an interaction module.

[0009] Preferably, the detection module includes a detection control unit and a low-power Bluetooth, and the detection control unit is electrically connected to the receiving module.

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0018] Example 1 like Figures 1-2 As shown, this utility model provides an integrated device for detecting, measuring, and mapping railway optical cable routes. It includes a transmitting module, a receiving module, a detection module, a positioning and measurement module, a drawing module, an interactive module, a power supply module, a switch button, and a communication module. It integrates detection, measurement, and drawing functions and is designed specifically for the field of railway optical cable management.

[0019] The transmitting module consists of a microcontroller unit (MCU) (STM32H503), a clock generator (Si5351A), a digital potentiometer (MCP41010), a power amplifier (IRS2092), a high-frequency transformer (EI33), a resonant capacitor array (CBB81), a switch, a lithium battery power supply (4S1P18650), and a signal transmitting clamp (Eagle Test S180D-TX). All components are electrically connected, and the signal transmitting clamp is electrically or coupled to the cable under test. During operation, the cable under test is connected, and the switch is turned on. The MCU directs the components to work together. First, the Si5351A generates a specific frequency signal, the MCP41010 adjusts the amplitude, the IRS2092 amplifies the power, and then the EI33 and resonant capacitors boost and select the frequency, converting the 12V square wave into a sine wave signal of several hundred volts and radiating it out, thus transmitting a specific frequency electromagnetic wave signal.

[0020] The receiving module is specifically designed to receive electromagnetic wave signals induced by underground cables. Its core components include a receiver control unit (MCU) (STM32H503), a hollow induction coil wound with 20 turns of 0.8mm high-temperature wire, a signal amplifier (AD8428), a filter (LTC1068), a signal sampler (ADS1256), and a detector (STM32F446). All components are tightly connected via electrical signals. During operation, the MCU first regulates the induction coil to reach a resonant state to effectively capture the signal. Then, the AD8428 amplifies the weak signal, the LTC1068 performs tracking bandpass filtering to accurately extract the target frequency band, and the ADS1256 performs 24-bit high-precision sampling. Finally, the STM32H503 performs FFT transformation and peak detection to comprehensively analyze and output key parameters such as the amplitude, phase, and frequency of the induced electromagnetic wave signal.

[0021] The detection module mainly consists of a detection control unit (MCU, STM32H503) and a Bluetooth Low Energy module (nRF52832-QFAA). These two components are tightly connected via electrical signals, and the MCU also maintains electrical connections with the receiving module and the interaction module. The module's function is to receive signal information from the receiving module, perform in-depth analysis of these signals' strength using the MCU, accurately determine the extension direction of the underground cable, pinpoint its location, and transmit the data, including the cable's location and detailed signal information, to the interaction module via the Bluetooth Low Energy module for clear display, providing users with intuitive and accurate detection results.

[0022] The positioning and measurement module consists of a multi-frequency GNSS antenna (Beitian BT-4820), a high-channel OEM board (Hexin Xingtong UM980), an IMU (miniaturized IG-F90), Bluetooth Low Energy (nRF52832-QFAA), and an industrial-grade housing. During operation, the multi-frequency GNSS antenna captures GNSS signals across the entire frequency band. The high-channel OEM board calculates centimeter-level precise coordinates at a frequency of 20Hz. The IMU eliminates coordinate drift, ensuring positioning stability. The STM32H503 then aggregates and processes positioning, tilt, and power data. Finally, data is transmitted back in real-time via Bluetooth Low Energy (BLE) to acquire cable path trajectory data and accurately measure distances between specified locations.

[0023] The drawing module is based on the B9000 device, running the Android 8.0 operating system, equipped with an MTK6757 octa-core 2.6GHz processor, and has a storage combination of 6GB RAM + 128GB ROM. It has module scheduling, data calculation, and storage capabilities. It receives cable route data calculated by the detection module and location data obtained by the positioning module, and draws and saves the cable route trajectory data accordingly. It supports the generation of 2D route map CAD files and 3D GIS route map coordinate files. At the same time, it can export data through the data communication module, calculate the trajectory and navigation position, control the interactive module to display specific content, and the drawing interactive module can be fixed to a specific position on the device via a mounting bracket and is detachable.

[0024] The power module is an electrical unit that provides power to the entire device. In this design, a 10000mAh 3S2P soft-pack lithium polymer battery is selected. It is connected to the receiving module, detection module, and positioning detection module via electrical signals, providing stable power to these modules and ensuring the normal operation of all parts of the device. It is the energy foundation for the continuous operation of the device.

[0025] The power button is an electrical unit that controls the on / off state of the device, used to power on and off. This solution uses the Hongyuan Kaitai LAS1-A waterproof, dustproof, and corrosion-resistant control button, which is electrically connected to the power module. Users can easily control the power supply to the device by operating this button, facilitating use and maintenance.

[0026] The communication module is a hardware unit with wireless or wired data transmission capabilities, responsible for enabling data transmission within the device. This solution uses the Quectel EC200A-CN 4G module for wireless data communication, enabling fast and stable data transmission from the device to the network. Simultaneously, a USB 3.2 Gen2 Type-C interface is used to export data files, facilitating user access to data from the device. It is electrically connected to the drawing interaction module to ensure smooth data transmission.

[0027] The interactive module uses a 5.5-inch high-definition touch screen and is connected to the drawing module via electrical signals. It provides users with a convenient operating interface and clear content display functions. Different information can be displayed in different modes. For example, the detection mode can display the cable location and cable trajectory, while the positioning mode can display the cable fault location point, current cable navigation indicator, etc., allowing users to intuitively understand the device's working status and related information.

[0028] The device's workflow consists of two main parts: path acquisition and positioning / navigation. First, the transmitting module is switched on, and the signal transmitter clamp is connected to the cable under test. The operator starts the device, the drawing module is set to detection mode, and all modules begin operation. The device moves gradually from the cable's starting point. The receiving module continuously receives the transmitted signals and transmits them to the detection module for output. Simultaneously, the interaction module updates the direction indicator. The positioning module acquires the current device position in real time and transmits it to the drawing module. Based on the current position data, the drawing module filters out abnormal data, calculates the correct optical cable path, and displays it on the interaction module's screen. Once the entire cable has been traversed, the device outputs an optical cable path map, including the actual geographical trajectory and length, which is stored within the device and can be transmitted to other systems via the communication module.

[0029] The operator starts the device, and the drawing module is set to positioning mode. The drawing interaction module and the positioning measurement module work simultaneously. First, the user selects the faulty cable in the interaction module, then inputs the distance to the fault point. The drawing module calculates the geographical location of the fault point based on the selected cable's geographical trajectory and the distance to the fault point. Finally, the positioning measurement module obtains the current location in real time, and the interaction module quickly guides the user to the fault location using map navigation, thus achieving rapid fault point location.

[0030] Therefore, this utility model adopts the above-mentioned integrated device for detecting, measuring, and mapping railway optical cable routes. By emitting electromagnetic wave signals of a specific frequency and receiving electromagnetic waves induced by underground cables, the device can accurately detect the direction and location of the cable. At the same time, combined with a high-precision positioning and measurement module, the device can obtain equipment location information in real time and draw a cable route map based on geographic coordinates, realizing full automation from detection to drawing. Based on the current location and the distance to the cable fault point, the device guides the operators to quickly reach the actual location of the cable fault point using map navigation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
