[0038] According to an embodiment of this utility model, a co-frequency relay device for a planar shunting system is provided, comprising: a metal shell 1, a partition 2, a power module 3, a transceiver module 4, a wireless communication module 5, a control module 6, a display module 7, a radio frequency module 8, and an antenna and interface module 10.

The top plate, bottom plate, two side plates, front plate, and rear plate form a receiving cavity. The rear plate has a wiring opening for the power cord of the power module 3 to pass through. The metal casing 1 has a simple structure, is easy to process and manufacture, and reduces costs.

[0041] Furthermore, through precision machining and sealing, the various parts of the metal shell 1 are tightly integrated, effectively preventing electromagnetic wave leakage and minimizing electromagnetic radiation emissions, thereby improving the electromagnetic compatibility of the equipment.
[0042] In one embodiment, the same-frequency repeater also includes a drawer located in the upper cavity. Two side panels, a top panel, and a front panel form a front opening. The drawer is pull-out mounted on a partition 2 through the front opening. The power module 3, transceiver module 4, wireless communication module 5, and control module 6 are all housed in the drawer. A wiring opening is provided on the drawer door. By placing the various modules located in the upper cavity in the drawer, the drawer can be pulled out for maintenance and pushed back in after maintenance, facilitating maintenance. The wiring opening on the drawer door facilitates wiring.
[0043] In one embodiment, a seal is provided at the wiring opening. The seal is made of electromagnetic shielding material.

The drawer is supported by the left panel 201 and the right panel 202, making the drawer pull-out more stable and reliable.
[0045] It is understood that, in another embodiment, such as Figure 5 As shown, the left plate 201 and the right plate 202 are connected to form a partition 2.
[0046] In one embodiment, the antenna is made of electromagnetic shielding material, which has good conductivity and magnetic permeability, and can effectively absorb, reflect and cancel external electromagnetic interference, thereby protecting the internal circuitry of the device from interference.
[0047] In one embodiment, the control module 6 includes a circuit board made of electromagnetic shielding material. The electromagnetic shielding material has good conductivity and magnetic permeability, and can effectively absorb, reflect and cancel external electromagnetic interference, thereby protecting the internal circuitry of the device from interference.
[0048] In one embodiment, a pad is provided at the interface of the interface module 10. The pad is made of electromagnetic shielding material. Using electromagnetic shielding material for the pad can further enhance the electromagnetic shielding performance of the device and effectively reduce the impact of external electromagnetic interference on the internal circuit.
[0049] It should be noted that, in addition to the antenna, circuit board, gasket, and seals which use electromagnetic shielding materials, other components can also use electromagnetic shielding materials.
[0050] In one embodiment, control module 6 includes a processor and a memory. The memory stores train operation data and historical records, while the processor analyzes and processes the operation data and historical records. The co-frequency transfer device integrates a processor and memory, enabling it to store large amounts of operation data and historical records. It then analyzes and processes this data using algorithms to achieve intelligent decision-making and prediction, meeting the demands of modern railway transportation for intelligence and automation, thus upgrading the intelligence and automation of the co-frequency transfer device. By combining the processor and memory with built-in algorithms and logic modules to achieve adaptive learning, the device can analyze historical data, learn and identify the optimal parameter settings and strategies under different environmental conditions, and then automatically adjust these parameters and strategies according to the current environment.
[0051] Furthermore, in terms of automatically adjusting parameters and strategies based on historical data and the current environment, the same-frequency repeater analyzes and judges data through built-in algorithms and logic modules. Specifically, the device periodically collects and analyzes operational data, including signal strength, interference levels, and device temperature, and compares it with historical data. If the current environment matches a pattern in the historical data, the device will automatically adopt the parameter settings and strategies validated under that pattern. For example, in environments with low signal strength or high interference, the device may automatically adjust its transmit power or modulation method to improve communication quality. In addition, the device may also adjust parameters such as filter settings and frequency allocation, and formulate strategies such as communication priority and fault response to adapt to different environments and needs.
[0052] Furthermore, the same-frequency repeater enables remote monitoring and control functions through its built-in communication modules and network interfaces. These modules are also responsible for communication and data exchange with other devices or systems. This allows maintenance personnel to remotely monitor the equipment's operating status, set parameters, and diagnose faults, greatly improving maintenance efficiency and convenience.
[0053] In one embodiment, the processor includes a control unit, a logic operation unit, and a digital signal processing unit. The control unit generates control signals according to instructions, the logic operation unit performs operations and logical calculations, and the digital signal processing unit processes the signals. The digital signal processing unit uses digital signal processing technology to encode, modulate, and demodulate the signals, effectively reducing signal attenuation and distortion during transmission, and further improving signal transmission efficiency and stability. Digital signal processing technology is a comprehensive field, and its structure mainly includes key stages such as signal acquisition, signal preprocessing, signal analysis and transformation, signal processing algorithm design, and signal processing result output. In the signal acquisition stage, analog signals are first converted into digital signals through an analog-to-digital converter (ADC), ensuring the digital representation of the signal. Next, in the signal preprocessing stage, the acquired digital signals are filtered and denoised to improve the signal-to-noise ratio and accuracy.
[0054] Furthermore, signal processing technology is employed to filter and denoise the received signal, further enhancing its anti-interference capability. The same-frequency repeater also features adaptive adjustment, automatically adjusting parameters according to changes in the surrounding environment to cope with different interference situations. This adaptive adjustment function is achieved through an intelligent control unit, which receives the collected data and analyzes and processes it using built-in algorithms. Based on the analysis results, the intelligent control unit automatically adjusts the equipment's parameter settings, such as signal gain, frequency selection, and filters, to adapt to different working environments and interference conditions. This adaptive adjustment function enables the equipment to maintain stable performance in the complex and ever-changing railway environment, improving communication reliability and efficiency.
[0055] To reduce maintenance costs and improve system reliability, the same-frequency repeater also features self-diagnosis and fault repair capabilities. Its memory stores fault prediction models, using software algorithms and data analysis techniques to monitor the equipment's operating status and predict potential faults in real time. The system assesses its health by collecting and analyzing various data generated during operation (such as operation logs, performance indicators, and user feedback). This data is processed by specific algorithms to identify any anomalies or potential problems. Once the system detects an anomaly or predicts a possible fault, it immediately issues an alarm and makes a preliminary judgment on the fault type using built-in fault prediction models. These models, built on historical data and expert knowledge, can accurately predict the fault type and possible causes. Based on fault prediction, the equipment automatically adjusts equipment parameters, optimizes operating strategies, or triggers specific maintenance tasks to prevent or mitigate the impact of faults. If the equipment cannot resolve the fault itself, it sends relevant information to maintenance personnel for timely manual intervention. By utilizing software algorithms and data analysis techniques, the equipment achieves self-diagnosis and fault prediction without relying on traditional physical sensors and detection circuits. This not only reduces hardware costs and maintenance complexity but also improves system reliability and availability.
[0056] It should be noted that the power module 3, transceiver module 4, wireless communication module 5, control module 6, display module 7, radio frequency module 8, antenna, and interface module 10 can adopt the structure of existing technology, and will not be described in detail here. The software algorithm, fault prediction model, etc., which are not described in detail above, are also conventional technologies in existing technology, and will not be described in detail here.
[0057] It's worth noting that a wireless communication module is an integrated unit that contains all the necessary components for sending and receiving wireless signals, typically including a baseband processor, memory, antenna interface, power management, and other key components. Wireless communication modules usually embed a complete communication protocol stack, capable of independently completing all tasks related to wireless data transmission, including signal encoding, decoding, encryption, decryption, error checking, and packet reassembly. A wireless communication module can function as a standalone unit, communicating directly with applications or other systems without additional hardware or software support. It can operate independently, providing complete wireless data transmission services and supporting various wireless communication protocols such as Wi-Fi, Bluetooth, Zigbee, LoRa, NFC, and cellular networks (e.g., 2G, 3G, 4G, 5G). Transceiver module 4 typically refers to a hardware component specifically designed for transmitting and receiving radio signals. It mainly includes radio frequency (RF) components such as mixers, amplifiers, and filters, used for signal modulation and demodulation, frequency conversion, and signal strength adjustment. However, transceiver module 4 often does not contain complete baseband processing capabilities and may not be able to independently handle advanced data encoding, decoding, protocol stack, and other functions. In practice, these functions are usually handled by an external microprocessor or microcontroller.
[0058] In current railway shunting systems, same-frequency transponder equipment plays a crucial role in connecting various shunting units and ensuring smooth information transmission. However, existing same-frequency transponder equipment still has certain limitations in terms of technology and performance, specifically as follows:
[0059] 1. Traditional same-frequency repeater equipment is significantly limited in signal transmission distance and cannot meet the needs of long-distance communication. Due to the long railway lines and complex environment, the communication distance between equipment is often long. However, traditional equipment has limited ability to handle signal attenuation and interference, resulting in decreased signal quality or even communication interruption during long-distance transmission.
[0060] 2. Existing co-frequency repeater equipment is insufficient in its anti-interference capability. In railway systems, there are numerous sources of electromagnetic interference, such as the electromagnetic field generated by locomotive operation and the power lines of electrified railways. These sources can severely affect the normal operation of co-frequency repeater equipment, leading to problems such as signal distortion and increased bit error rate.
[0061] 3. Communication between equipment is prone to interruption: Due to limitations in hardware performance and algorithm design, communication between equipment may be interrupted when faced with environmental changes or complex signals, which may pose a risk to shunting operations.
[0062] 4. Traditional co-frequency repeater equipment has limited self-diagnosis and fault repair capabilities. When equipment malfunctions, manual troubleshooting and repair are often required, which not only increases maintenance costs but also affects system operating efficiency.
[0063] 5. The intelligence and automation of the same-frequency relay equipment still need improvement. With the rapid development of railway transportation, the requirements for the intelligence and automation of the shunting system are also increasing, and there is still considerable room for improvement in traditional equipment in this regard.
[0064] In summary, traditional co-frequency repeater equipment has certain limitations in terms of signal transmission distance, anti-interference capability, self-diagnosis and fault repair capability, as well as intelligence and automation, and cannot meet the requirements of modern railway transportation for high efficiency, stability and safety.
[0065] In this embodiment, the same-frequency repeater optimizes signal transmission by employing radio frequency technology and digital signal processing technology, achieving a longer signal transmission distance. This effectively solves the limitations of traditional equipment in terms of signal attenuation and interference, ensuring stable communication of the shunting system at different distances. The digital signal processing unit encodes, modulates, and demodulates the signal, reducing attenuation and distortion during transmission and improving the signal's anti-interference capability, resulting in clearer, more accurate, and higher-quality received signals. Optimized signal transmission, through the use of a metal casing, electromagnetic shielding materials, and signal processing technology, effectively resists external electromagnetic interference, ensuring normal operation in complex electromagnetic environments. The same-frequency repeater can automatically adjust parameters according to changes in the surrounding environment to cope with different interference situations, further improving the equipment's anti-interference capability and enabling adaptive adjustment. Upon detecting a fault, it can attempt automatic repair, reducing the need for manual intervention and lowering maintenance costs. The built-in processor and memory store and analyze operational data, using intelligent algorithms for decision-making and prediction, improving the system's intelligence level. The equipment also supports remote monitoring and control functions, enabling maintenance personnel to remotely monitor, set parameters, and diagnose faults, improving the convenience and efficiency of maintenance. The same-frequency relay equipment in this embodiment employs advanced radio frequency technology, digital signal processing technology, anti-interference technology, self-diagnosis and fault repair technology, as well as intelligent and automated technologies. It comprehensively optimizes and upgrades traditional same-frequency relay equipment in planar shunting systems, not only solving the problems and limitations of existing technologies but also significantly improving the system's stability and reliability, meeting the demands of modern railway transportation for efficient, stable, and safe shunting systems. Compared with traditional same-frequency relay equipment, the same-frequency relay equipment in this embodiment demonstrates significant advantages and beneficial effects in signal transmission, anti-interference capabilities, self-diagnosis and fault repair, and intelligent and automated technologies. It not only improves the stability and reliability of the shunting system but also reduces maintenance costs and enhances the overall operational efficiency and safety of the railway system.
