Description

Technical Field

[0001] This utility model relates to the field of railway shunting technology, and in particular to a handheld railway shunting device. Background Technology

[0002] Currently, handheld devices used in railway shunting operations are mainly divided into single-function specialized equipment combinations. The objective shortcomings of existing technologies are primarily reflected in functional fragmentation, operational redundancy, and insufficient system compatibility. Traditional 400MHz analog handheld radios, limited by a single communication mode, cannot achieve full-scene coverage and lack data interaction capabilities with modern dispatching systems. This forces critical information in shunting operations to still rely on manual relaying or paper records, resulting in low efficiency and increased risk of human error. While emerging multi-functional devices on the market have achieved initial integration of communication and positioning functions, they have revealed systemic defects in practical applications: multiple service functions are simply stacked together without establishing an organic collaborative mechanism. For example, positioning data cannot automatically trigger protective alarms, and shunting plan transmission and signaling systems remain separate, forcing operators to repeatedly operate different functional modules. This fragmented operation mode directly increases the number of invalid operation steps in a single shunting operation by more than 40%, requiring operators to perform an average of 17 function switching operations per shift, severely dragging down operational efficiency.

The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description, claims, and drawings.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Currently, handheld devices used in railway shunting operations are mainly divided into two categories: one is the traditional 400MHz analog handheld radio, which only supports basic voice communication and shunting signaling, and cannot access the GSM-R digital network. This results in insufficient data transmission capacity and a lack of high-precision positioning capabilities, requiring operators to carry additional positioning terminals. The other category is the multi-functional smart terminal that has emerged in recent years. Although it integrates some digital functions, it generally suffers from insufficient system stability, complex operating logic, and poor battery life. For example, some devices use touchscreen operation, which is prone to malfunction in rainy or snowy weather or when wearing gloves, while physical button devices cannot support complex data interaction needs. In addition, the positioning accuracy of existing devices is usually only at the meter level, which cannot meet the centimeter-level positioning requirements for vehicles and personnel in shunting operations, rendering safety protection functions ineffective.

[0027] Based on this, the railway shunting handheld device provided by this utility model embodiment can improve the problem of functional separation in the prior art and improve the efficiency and safety of shunting operations.

[0028] To facilitate understanding of this embodiment, a detailed description of a railway shunting handheld device disclosed in this utility model embodiment will be provided first, see [link to relevant documentation]. Figure 1 The diagram shown is a front view of a railway shunting handheld device, illustrating that the handheld device includes an external structure and an internal structure. The external structure includes a main unit and an antenna, and the main unit includes a screen and buttons. The internal structure includes a communication module and a positioning module.

[0029] The communication module is used to receive shunting signals and transmit the locations of shunting crew members and vehicles to the shunting center. It includes a DMR digital radio unit and a 4G / 5G full-network compatible unit. The DMR digital radio unit uses the 400MHz frequency band for communication, and the 4G / 5G full-network compatible unit uses 4G / 5G full-network compatible communication. Specifically, in terms of communication, the equipment adopts a dual-mode design of DMR digital radio and 4G / 5G full-network compatible communication, supporting both the 400MHz frequency band and 4G full-network compatible communication.

[0030] The positioning module uses single-BeiDou RTK high-precision positioning technology to locate the positions of shunting crew personnel and vehicles. Specifically, the positioning module uses single-BeiDou RTK high-precision positioning technology, with a horizontal positioning accuracy of 1cm+1ppm CEP and a vertical accuracy of 0.02m, far exceeding the accuracy of traditional GPS. It can track the positions of shunting crew personnel and vehicles in real time and link with the electronic fence of the dispatching system to achieve precise safety protection.

[0031] The main unit also includes a speaker, a microphone, and a positioning and marking button; the positioning and marking button is located on the top of the main unit and is a concave button used for positioning and marking during operation.

[0032] The buttons include: red, yellow, and green signaling buttons, device function buttons, PTT call buttons, and extended function buttons; the speaker is located at the top of the screen, the microphone is located at the lower part of the front of the main unit, the screen is located at the upper part of the front of the main unit, the red, yellow, and green signaling buttons and device function buttons are located in the middle of the front of the main unit, and the PTT call buttons and extended function buttons are located at the upper left side of the main unit. The extended function buttons are used for shunting voice route query and protection broadcast information replay; the red, yellow, and green signaling buttons are convex buttons, higher than the main unit's panel, and the device function buttons are concave buttons, parallel to the main unit's panel.

[0033] In this embodiment, the main unit measures 138mm (length) × 56mm (width) × 36.8mm (depth) and weighs 390g. The antenna is approximately 152mm long and uses a soft rubber structure. The handheld device features a 2.4-inch high-definition semi-transparent color screen located on the upper half of the front of the main unit, facilitating the viewing of relevant smart information by the operator.

[0034] See Figure 1 As shown, the speaker and microphone are separate (the microphone is located on the top, and the speaker is located at the bottom of the front of the main unit), thus solving the problem of mutual interference between playback and sound reception. The top features recessed buttons as positioning and marking buttons for work positioning and marking.

[0035] The buttons include red, yellow, and green signaling buttons, device function buttons, PTT call buttons, and extended function buttons. See also Figure 2 As shown, the red, yellow, and green signaling buttons are colored according to railway standards, and the size, position, and spacing of the three buttons are strictly set according to railway standards. The red, yellow, and green signaling buttons are convex buttons, protruding 1.5mm from the equipment structure (i.e., the main unit) panel, which facilitates the issuance of shunting signals during on-site shunting operations.

[0036] See Figure 3As shown, the device's function keys are arranged in a nine-grid layout, mainly including menu, scroll up, scroll down, power on / off / return, and other function keys. The height of the device function keys and the red, yellow, and green signaling keys are differentiated, and the device function keys are concave and parallel to the device's structural panel.

[0037] See Figure 4 As shown, the PTT call button is located on the upper left side of the host, and it is a large button (28*13mm in size). There are also two extended function buttons on the left side, which are used for shunting voice route query and protection broadcast information replay respectively.

[0038] Further, see Figure 1 and Figure 5 As shown, the main unit also includes: volume control buttons, indicator lights, a battery, a charging port, and a battery latch. The volume control buttons and indicator lights are located on the top of the main unit. This utility model's battery supports Type-C and desktop charger charging, making charging more convenient and faster.

[0039] The handheld device provided by this utility model features a small screen design, physical buttons, and an IP68 protection rating. It is designed specifically for shunting personnel and meets the requirements of on-site environments and operation while wearing gloves.

[0040] In one implementation, the communication module is also used to connect to the railway TDCS / CTC system via the NMEA 0183 and RTCM 3.x protocols, and to receive shunting plan information sent by the railway TDCS / CTC system. Specifically, by supporting the NMEA 0183 and RTCM 3.x protocols, the communication module allows the device to be directly connected to the existing railway TDCS / CTC system without additional modifications. For example, in a test at a marshalling yard, this device can integrate the processes of shunting plan transmission, signaling, and location feedback into a single terminal operation, reducing the weight carried by operators from 3.2kg to 390g, and reducing the number of operation steps per shift by 40%.

[0041] Furthermore, the internal structure also includes: an alarm module, a recording module, and an AI noise reduction module.

[0042] The alarm module receives safety alerts and broadcasts protective audio messages to workers via loudspeakers. Specifically, the alarm module can use loudspeakers to deliver precise safety information based on tiers, categories, and roles. Furthermore, it can automatically broadcast work order plans and work hook details.

[0043] The recording module is used to record the operators' conversations in real time and supports TF card storage of recordings.

[0044] The AI ​​noise reduction module is used to reduce noise in the conversations of workers, which can meet the needs of users in different environmental scenarios.

[0045] For ease of understanding, the present invention also provides the technical parameters of the handheld device, as shown in Table 1.

[0046] Table 1 Technical parameters of handheld devices

[0047]

[0048] The railway shunting handheld device provided by this utility model integrates DMR+4G / 5G communication, high-precision positioning, and intelligent technology, combining multiple functions into one device. Shunting operators only need one device to support all shunting and protection operations on site, without changing the operators' habits, adding operation safety reminders and warning functions, and can block and control when necessary, reducing the burden on operators.

[0049] In terms of communication, the equipment adopts a dual-mode design with DMR digital radio and 4G / 5G full network compatibility, supporting 400MHz frequency band and 4G full network communication. The positioning module uses single Beidou RTK high-precision positioning technology, with a horizontal positioning accuracy of 1cm+1ppm CEP and a vertical accuracy of 0.02m, far exceeding the accuracy of traditional GPS. It can track the location of shunting crew personnel and vehicles in real time and link with the electronic fence of the dispatching system to achieve precise safety protection.

[0050] In terms of human-computer interaction, the equipment retains the physical button layout familiar to railway workers (including red, yellow and green signaling buttons and a large 28×13mm PTT button), and is equipped with a 2.4-inch semi-transparent color screen that is visible under strong light and supports operation while wearing gloves, completely solving the problem of touch screen devices being prone to failure in harsh environments.

[0051] This invention significantly improves the efficiency and safety of shunting operations in multiple dimensions. Firstly, the deep integration of communication and positioning enables the device to transmit high-precision location data to the dispatch center in real time, while supporting parallel voice and data transmission, reducing the signaling response time from 2.3 seconds to 0.8 seconds compared to traditional solutions. Secondly, the collaborative design of physical buttons and a smart screen preserves the operating habits of workers while expanding data interaction capabilities, with actual tests showing a 92% reduction in the error rate. Regarding battery life, the 3000mAh battery, combined with Type-C / desktop charging dual modes, supports 12 hours of continuous operation, reducing charging frequency by 67% compared to discrete equipment solutions.

[0052] The standardized integration of functional modules solves the compatibility issues between devices from different vendors. By supporting the NMEA 0183 and RTCM 3.x protocols, the equipment can be directly connected to the existing railway TDCS / CTC system without additional modifications.

[0053] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
