Description

Technical Field

[0001] This utility model relates to the field of railway locomotive communication equipment technology, specifically providing a new type of intelligent prevention and control auxiliary equipment. Background Technology

[0002] In the railway transportation sector, shunting operations are a core function ensuring the smooth operation of crucial processes such as train marshalling, dismantling, and vehicle movement. Traditional horizontal shunting systems primarily consist of shunting terminals, such as the shunting yard controller, locomotive controller, and handheld radios. The handheld radios send shunting commands to the locomotive controller, directing its operation. Upon receiving the commands, the locomotive controller issues audio and visual cues, which the driver then uses to operate the locomotive. Communication between the locomotive controller and the handheld radios is also possible via voice. The shunting yard controller, located in the ground signal tower, manages the operations within the shunting yard. Each shunting group uses a single frequency channel and is equipped with one locomotive controller and multiple handheld radios. When multiple shunting groups are operating simultaneously, the shunting yard controller operates in scanning mode. It only engages with the frequency channel of a shunting group when the group sends a call signal; after the call ends, scanning resumes. When a single shunting crew is operating, the shunting supervisor's console is in monitoring mode, allowing them to communicate with the shunting crew at any time. All voice communications and instructions from the shunting crew can be played through the shunting supervisor's console, enabling the shunting supervisor to understand the operational situation on site.

[0003] However, with the rapid development of the railway industry and the continuous expansion of station scale, the independent operation mode of multiple shunting yards within large and medium-sized marshalling yards has gradually exposed many problems, making it difficult to meet the needs of centralized and intelligent modern railway dispatching. Existing planar shunting systems have significant limitations in wireless communication: signaling transmission mainly relies on analog signals, which are easily affected by external interference, information transmission is prone to loss, and the transmission speed is slow with limited encoding capacity, making it difficult to adapt to the development trend of modern wireless communication technology; shunting operation signals are mostly input via buttons, posing a risk of misoperation; although communication content includes voice calls and shunting instructions, data transmission is unidirectional, lacking centralized storage and encryption methods, making effective traceability and confidentiality impossible. Especially with large data volumes, data compression technology is urgently needed to optimize storage and transmission efficiency to cope with the ever-increasing data processing demands.

[0004] More seriously, the existing system cannot continue operating in the event of a power outage, posing a significant safety hazard and failing to meet the stringent requirements of continuity and safety in dispatching operations. Furthermore, the signaling transmission methods in traditional shunting systems are relatively simple, making it difficult for shunting personnel to quickly and intuitively obtain signaling information in complex operational environments. This can easily lead to inefficiencies and even safety hazards due to misunderstandings or delays in signaling. Simultaneously, previous systems lacked effective on-site signaling monitoring and display methods, resulting in opaque signaling status during shunting operations. This hinders the timely detection and resolution of anomalies in signaling transmission, making it difficult to meet the increasingly sophisticated management needs of railway shunting operations.

[0005] In view of the above problems, there is an urgent need for an advanced intelligent prevention and control auxiliary device that can realize real-time, multi-band, two-way transmission of shunting instructions and voice communication data, support centralized data storage, encryption processing and compression, and have the ability to continue operation after power failure, intuitive signaling display function and efficient abnormal monitoring and alarm mechanism, so as to comprehensively improve the safety, reliability and efficiency of shunting operations and meet the needs of modern railway transportation development. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a new type of intelligent control auxiliary equipment that addresses the shortcomings of the prior art. This equipment has a simple structure and reasonable design. It realizes the real-time reception, storage and forwarding of shunting signaling and call recording, thereby improving the safety and efficiency of shunting operations.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A novel intelligent control auxiliary device, characterized in that it comprises: an antenna unit for receiving signaling and audio signals sent by a shunting terminal; the antenna unit includes multiple antennas for receiving shunting signaling and voice communication data in different frequency bands to improve the stability and reliability of signal reception; a radio frequency (RF) unit connected to the antenna unit for performing RF processing on the signaling and audio signals, and then distinguishing the processed signals and sending them separately to a signaling transceiver unit and an audio transceiver unit; a signaling transceiver unit connected to the RF unit for demodulating the received signaling RF signals into digital signals and sending them to a main control service unit; an audio transceiver unit connected to the RF unit for demodulating the received audio RF signals into analog signals and sending them to the main control service unit; and a main control service unit connected to the signaling processing unit and the audio transceiver unit, and pushing data to the business center in real time.

[0009] The aforementioned shunting control signaling recording synchronization gateway is characterized in that the main control service unit is further used to receive instructions from the business center and send instructions to the shunting terminal through the signaling transceiver unit, the signaling transceiver unit, the radio frequency unit, and the antenna unit.

[0010] The aforementioned shunting control signaling recording synchronization gateway is characterized in that it includes an internal power supply unit, wherein the internal power supply includes a built-in battery and a power conversion module for converting 220V DC power to 12V DC power.

[0011] The aforementioned shunting control signaling recording synchronization gateway is characterized in that the radio frequency unit includes a key encoding and decoding device for encoding and decoding the received and transmitted signals.

[0012] The aforementioned shunting control signaling recording synchronization gateway is characterized in that the main control service unit includes a key encoding and decoding device, used to encrypt data sent to the business center and decrypt data received from the business center.

[0013] The aforementioned shunting control signaling recording synchronization gateway is characterized in that the main control service unit includes a signaling and audio synchronous processing unit, which is used to perform synchronous processing of signaling and audio data, to temporarily store the received data, and to preprocess the received data, including data format conversion and data compression.

[0014] The aforementioned shunting control signaling recording synchronization gateway is characterized in that the main control service unit communicates with the business center via a wireless connection.

[0015] The aforementioned shunting control signaling recording synchronization gateway is characterized in that the main control service unit communicates with the business center via a communication cable connection.

[0016] The aforementioned shunting control signaling recording synchronization gateway is characterized by comprising a signaling processing unit, which is connected to the signaling transceiver unit and the light display unit, which is connected to the signaling processing unit and is used to display data content.

[0017] The aforementioned shunting control signaling recording synchronization gateway is characterized by including indicator lights of various colors and an LCD screen, which are used to intuitively display data content through the arrangement of different colored indicator lights and the display screen. The main control service unit is also used to monitor the working status of each unit and issue an alarm through the indicator light unit when an abnormality is detected.

[0018] The beneficial effects of this application are as follows:

[0019] Analog-to-digital signal conversion enables group transmission: Converting analog signals to digital signals greatly improves the flexibility and efficiency of signal processing. Traditional analog signals are susceptible to interference during transmission and cannot be easily transmitted in groups. However, the signaling transceiver unit 4 in this device can demodulate the received signaling radio frequency signals into digital signals. This conversion not only enhances signal stability and anti-interference capabilities but also allows digital signals to be sent to multiple target devices simultaneously, achieving true group transmission functionality. This improvement significantly enhances the efficiency and flexibility of shunting operations, enabling shunting instructions to be quickly and accurately transmitted to all relevant shunting terminals, reducing information transmission delays and errors, and optimizing the overall shunting operation process.

[0020] The system enables unified storage of signaling and voice data in the railway system: The main control service unit 6 integrates and compresses signaling, clock, and audio information before sending it to the business center 7, where it also stores this critical information in its internal memory. This design effectively solves the problem of scattered storage of signaling and voice data in traditional shunting systems, preventing information loss or asynchrony. Through unified storage, the railway system can more conveniently query, analyze, and trace data, ensuring that every step of shunting operations is traceable. This not only improves the integrity and security of the data but also provides strong support for efficient railway system management and accident analysis, enabling managers to quickly and accurately obtain historical shunting data for operational analysis and optimization decisions.

[0021] To enhance the safety and reliability of railway shunting operations, this equipment employs multiple mechanisms. The key encoding / decoding devices in the radio frequency unit 3 and the main control service unit 6 encrypt signaling and voice data, preventing information leakage and malicious eavesdropping, thus ensuring the confidentiality of shunting instructions and communication content. Simultaneously, the anomaly monitoring and alarm system constantly monitors the operational status of each unit. Upon detecting any anomalies, an alarm is immediately issued via the indicator unit 8, alerting staff to take timely measures to prevent potential safety accidents, effectively improving the safety and reliability of shunting operations.

[0022] Enhancing the system's flexibility and adaptability, the system not only supports sending data to the business center but also possesses reverse operation capabilities, allowing the business center to send signaling and voice commands to the shunting terminal as needed. This two-way communication capability enriches the system's operating modes and enhances its flexibility and adaptability. Whether it's routine shunting operation command or issuing instructions in emergency situations, the system can respond quickly and execute accurately, meeting the diverse needs of railway shunting operations in different scenarios.

[0023] To optimize data transmission and storage efficiency, the main control service unit 6 integrates and compresses signaling, clock, and audio information before sending it to the business center 7. This data preprocessing method not only improves data transmission efficiency but also reduces storage space usage. Through data compression technology, large amounts of shunting operation data can be efficiently stored and managed, facilitating subsequent data analysis and mining, and providing a solid data foundation for the intelligent development of the railway system.

[0024] The equipment ensuring the continuity of shunting operations is equipped with an internal power supply unit. In the event of an external power outage, the built-in battery can quickly take over the power supply, ensuring the continuous and stable operation of the shunting control signaling recording synchronization gateway. This design effectively avoids interruptions in shunting signaling transmission and recording synchronization due to power supply disruptions, ensuring the continuity of shunting operations and providing strong support for the efficient and stable operation of railway transportation.

[0025] The signal processing unit 9 and the light display unit 8 work together to present signal information to shunting personnel in a clear and intuitive way. The light display unit 8 uses a combination of different colored signal lights and an LCD screen to transform complex signal content into easily understandable visual information, helping shunting personnel quickly identify signal commands and improving response speed and execution efficiency at the work site. This improvement effectively solves the problems of the traditional shunting system's single signal transmission method and the difficulty for shunting personnel to quickly obtain signal information, enhancing the controllability and safety of shunting operations.

[0032] The present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0033] It should be noted that, without causing conflict, the various embodiments mentioned in this application and the various features in these embodiments can be combined with each other. Next, the present invention will be analyzed in detail with reference to the accompanying drawings and embodiments.

[0034] It should be clarified that the technical terms used in this application are only for describing specific embodiments and are not intended to limit the scope of protection of this application. In the specification, claims and description of drawings of this application, the use of words such as "comprising" or "including" means that, without exclusive exclusion, the relevant features, steps, operations, elements or components are covered, while the presence of other features, steps, operations, elements or components not expressly listed is permitted.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are merely identifiers to distinguish different objects and are not intended to emphasize a specific order or priority. These terms can be used interchangeably where appropriate, and the embodiments described in this application can be performed in a different order than that shown in the drawings. Furthermore, terms such as "comprising," "having," and their derivatives indicate the presence of the listed steps or components, but do not exclude the presence of other unlisted steps or components.

[0036] For ease of description, this document uses spatial relative terms such as "above," "on top of," and "upper surface" to describe the spatial positional relationship between one element or feature and another. These relative terms are intended to cover different orientations that may occur during actual use or operation, in addition to those shown in the accompanying drawings. For example, if an element in the accompanying drawings is placed upside down, an element originally described as "above" will become "below." Therefore, the exemplary expression "above" should be understood to include both possible orientations of "above" and "below."

[0037] like Figure 1 As shown, the system includes multiple shunting terminals 1, antenna units 2, radio frequency units 3, signaling transceiver units 4, audio transceiver units 5, a main control service unit 6, and a service center 7. The shunting terminals communicate with antenna units 2 via different frequencies. Antenna units 2 are connected to radio frequency units 3 to acquire digital signals from the shunting terminals 1. These digital signals are processed by signaling transceiver units 4 and audio transceiver units 5, and then sent to the main control server. The main control service unit 6 compresses the signaling information, clock information, and audio information, and sends the clock information as a marker to the service center 7.

[0038] During shunting operations, smooth communication between each shunting terminal 1 and antenna unit 2 is ensured to prevent signal interference or interruption. The system can simultaneously send and receive signaling and audio information, which is compressed together with clock information by the main control service unit 6 and sent to the business center 7 to ensure data accuracy. Furthermore, the business center 7 backs up the data for quick and accurate subsequent querying and verification using clock information. The system also supports reverse operation, meaning the business center 7 can send signaling and voice commands to shunting terminal 1, effectively improving operational flexibility. By simultaneously sending and receiving signaling and audio information, and integrating and compressing it before sending it to the business center 7, the accuracy and integrity of the data are effectively ensured, preventing data loss or errors. The system design ensures smooth communication between each shunting terminal 1 and antenna unit 2, avoiding signal interference and interruption, significantly improving communication stability. The main control service unit 6 can efficiently integrate, compress, and forward signaling, clock, and audio information, improving data processing efficiency and optimizing the utilization of storage and transmission resources. The system supports reverse operation, meaning that the business center 7 can send signaling and voice commands to the shunting terminal 1 as needed, which enriches the operation mode and enhances the system's flexibility.

[0039] like Figure 2 As shown, a key encoding / decoding unit is added to both the radio frequency unit 3 and the main control service unit 6. This is because railway operations now require a higher level of security. The encoding / decoding key can be selected based on the management level, for example, different keys can be chosen. This allows for the protection of signaling and voice communication within the railway system.

[0040] In the shunting control signaling recording synchronization gateway shown in Figure 2, a key encoding / decoding unit is added to the radio frequency unit 3 and the main control service unit 6. The encoding / decoding keys can be selected according to different management levels, such as AES, 3DES, RSA, ECC, and IBE. In particular, the IBE key uses the user's identity information (such as employee ID, position, etc.) as part of the public key, while the private key is generated by the key generation center based on the identity information. In the railway system, managers and operators at different levels can use their respective IBE keys corresponding to their identity information, facilitating key management and distribution, and enabling fine-grained encryption control of signaling and voice, ensuring that only authorized personnel can decrypt and access the corresponding data.

[0041] like Figure 3As shown, the signaling transceiver unit 4 is connected to the signaling processing unit 9, which in turn is connected to the main control server unit and the indicator unit 8. The signaling transceiver unit 4 and the signaling processing unit 9 are closely connected, and the signaling processing unit 9 is further connected to the main control server unit 6 and the indicator unit 8. This structure, while ensuring secure and stable signaling transmission, utilizes the indicator unit 8 to achieve a more intuitive display of signaling information. Specifically, the indicator unit 8 uses a combination of different colored signal lights and an LCD screen to visually present signaling information from the shunting terminal 1 or the business center 7, enabling shunting personnel to quickly identify the signaling content and thus improving the response speed and execution efficiency of shunting operations.

[0042] This design addresses the following technical issues: First, traditional shunting systems rely on a single signaling transmission method, making it difficult for shunting personnel to quickly and intuitively obtain signaling information in complex work environments. This can easily lead to inefficiencies or even safety hazards due to misunderstandings or delays in signaling. Second, previous systems lacked effective on-site signaling monitoring and display methods, resulting in opaque signaling status during shunting operations. This hindered the timely detection and resolution of anomalies in signaling transmission, failing to meet the increasingly sophisticated management needs of railway shunting operations. This integrated signaling processing architecture with integrated light display unit 8 optimizes the signaling transmission and display process while enhancing the controllability and security of shunting operations, providing strong support for efficient railway shunting operations. This improvement effectively solves many information security problems in existing railway communication systems. On one hand, traditional communication methods are susceptible to malicious eavesdropping and hacking, posing a risk of leakage for critical data such as shunting commands and voice calls between the machine controller and handheld radio. The key encoding / decoding unit in this solution encrypts transmitted signals, ensuring the security of information at the air interface and preventing the leakage of sensitive information.

[0043] like Figure 4 As shown, the main control service unit 6 combines signaling information, audio information, and clock information, and sends the clock information as the marker information to the service center 7.

[0044] The shunting control signaling recording synchronization gateway, while powered by an external power source, also features an internal battery, thus accommodating both external power and internal battery power. As an indispensable and crucial component of the railway system, the shunting system, despite typically having a reliable power supply, can still experience occasional power outages during actual operation. In such cases, the built-in battery becomes particularly critical, as it can quickly take over power supply when the power grid fails, ensuring the continuous and stable operation of the shunting control signaling recording synchronization gateway. This prevents the forced cessation of shunting signal transmission and recording synchronization due to power outages, thereby guaranteeing the continuity and safety of shunting operations and providing solid support for the efficient and stable operation of railway transportation.

[0045] The main control service unit 6 includes a memory. This memory integrates and stores the main control service unit's signaling information, audio information, and clock information. This unified storage effectively solves the following key problems: During shunting operations, signaling information, audio information, and clock information are often scattered across different processing stages, lacking effective integration and centralized storage. This not only increases the complexity of data management but may also lead to information loss or asynchrony, thus affecting the accuracy and traceability of shunting operations. By storing this key information uniformly, subsequent data retrieval, analysis, and traceability are facilitated, ensuring that every stage of shunting operations is traceable. It also improves the integrity and security of the data, providing strong data support for efficient shunting operation management and accident analysis.

[0046] It should be noted that, for those skilled in the art, any parts not described in detail in this specification fall within the scope of common knowledge in the field. The embodiments provided by this utility model are only used to illustrate the core technology and are not intended to limit the scope of the technology. Based on the core idea of ​​this utility model, any simple modifications, adjustments, or equivalent structural transformations made to the embodiments should be included within the protection scope of this utility model.
