Description

Technical Field

[0001] This invention relates to work protection communication technology, and in particular to a work mode and joint control and reminder method based on a GSM-R network. Background Technology

[0002] Currently, railway engineering construction and protection communication mainly adopts the following methods: First, 400MHz walkie-talkies, which have the advantages of being ready to use immediately, allowing for push-button communication, and providing one-to-many responses. However, they have limited on-site communication distance, and the signal is poor in tunnels, especially in passing tunnels. Second, 4G network walkie-talkies, which are very similar in appearance and usage to 400MHz walkie-talkies. They overcome the distance limitations of wireless communication by leveraging the 4G network coverage of operators, but they cannot be used in areas without 4G network coverage, such as mountainous railways, especially some sections of conventional railways. Third, point-to-point communication via GSM-R handheld radios. This method is inconvenient on-site when there are many workers, as communication can only be done one by one. Fourth, voice conferences initiated using GSM-R handheld radios. However, this method has obvious drawbacks. When multiple people in the same conference group send voice messages simultaneously, multiple voices will be played at the same time, leading to confusion in communication information, easy mishearing or missing information, and high power consumption due to the large number of channels occupied. It is easy to mishear or miss one's own information. Voice conferences occupy many channels, which may cause congestion. High power consumption.

[0003] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] The main objective of this invention is to overcome the deficiencies in the aforementioned background technology and provide an operation mode and joint control reminder method based on GSM-R network.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A working mode and joint control reminder method based on GSM-R network, characterized by the following steps:

[0007] S1. In response to the job mode activation command, the terminal automatically deactivates all other group calls except for the specified job group call, and indicates job mode activation by switching the visual status indicator;

[0008] S2. In work mode, the work group call is initiated directly in response to the PTT button command, or a new work group call is switched and specified via navigation keys or touch operation;

[0009] S3. When the terminal joins the work group call, a timer is started to trigger a custom voice broadcast in a loop to remind the user to seize the uplink channel;

[0010] S4. After successfully detecting uplink channel preemption, stop the current voice broadcast; when the current timer expires, restart the timer to enter the next voice reminder cycle;

[0011] S5. In response to the command to exit the work mode, automatically restore the activation status of all group calls and the original visual status indicators.

[0012] Furthermore, in step S1:

[0013] The deactivation operation causes the terminal to only respond to job group calls and to be unable to initiate non-job group calls.

[0014] In step S5, the restored activation state allows the terminal to initiate and receive all calls from the original active group.

[0015] Further, step S2 includes:

[0016] Initiate a preset job group call directly in response to PTT button commands;

[0017] In the standby interface, you can use the arrow keys to traverse the group call list and update the selected group call to the current job group call in real time.

[0018] Furthermore, in step S3:

[0019] The content and frequency of the voice broadcast can be pre-configured by the user.

[0020] The timer is automatically initialized and started when a work group call is established.

[0021] Further, step S4 includes:

[0022] The voice broadcast continues in a loop until uplink preemption is detected as successful.

[0023] The timer restarts, triggering the next round of voice reminders.

[0024] Furthermore, the method also includes:

[0025] The name of the work group call can be customized and edited, and the customized name is displayed in real time on the incoming call interface, the call interface and the communication record.

[0026] Furthermore, when exiting a work group call, the voice broadcast will automatically terminate and the timer will stop.

[0027] Furthermore, the method is used in GSM-R handheld terminals and 5G-R mobile terminal devices.

[0028] Furthermore, in step S1:

[0029] The switching of the visual status indicator includes switching the terminal interface theme color to the job status indicator color. The theme color switching is used to explicitly distinguish the terminal status in job mode and non-job mode.

[0030] A computer program product includes a computer program that, when executed by a processor, implements the aforementioned GSM-R network-based operating mode and joint control reminder method.

[0031] The present invention has the following beneficial effects:

[0032] This invention provides a novel operational protection communication solution based on a railway private network GSM-R handheld terminal, offering a trunked communication solution with wider network coverage, lower resource consumption, and lower power consumption. This solution fully considers the on-site environment and business requirements of railway construction operations. By implementing a special group communication mode and joint control reminder method, it provides a safer and more efficient operational protection communication method while consuming fewer channel resources. Specifically, the solution activates an operational mode, causing the terminal to enter a state where only a single group (operation group call) is active, shielding it from the influence of other group calls. During the operation group call communication, it provides fixed-period voice reminders to the terminal user, effectively solving many problems in operational protection communication for railway construction.

[0033] Existing railway track maintenance and construction work safety communication methods generally suffer from incomplete network coverage and inconvenient operation. Although GSM-R networks have wide coverage, traditional GSM-R communication methods are not suitable for track maintenance and construction operations. In contrast, the professional operation mode developed based on GSM-R terminals in this invention features wider operation coverage, less network resource consumption, low power consumption, and low latency. It also has an automatic voice control reminder function, which can reduce repetitive and easily overlooked manual communication by track maintenance departments during safety operations, thereby reducing the accident rate of personnel injuries and fatalities on site. It is significantly superior to existing related technologies in terms of both safety and convenience.

[0034] Other beneficial effects of the embodiments of the present invention will be further described below. Attached Figure Description

[0036] Figure 2 This is a flowchart of a specific embodiment of the present invention. Detailed Implementation

[0037] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0038] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as "connected to" another component, it can be directly connected to or indirectly connected to that other component. Furthermore, a connection can be used for fixing, coupling, or communication.

[0039] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] This invention proposes a work mode and joint control reminder method based on a GSM-R network. Using a GSM-R handheld terminal, the method activates a single work group call and blocks interference from other groups by enabling the work mode, while providing periodic voice joint control reminders within the group call. Its significant technical advantages include wider network coverage, less channel resource consumption, lower power consumption, and reduced human error, thus improving work safety and efficiency.

[0042] See Figure 1 This invention provides a working mode and joint control reminder method based on a GSM-R network, characterized by the following steps:

[0043] Step S1. In response to the job mode activation command, the terminal automatically deactivates all other group calls except for the specified job group call, and indicates job mode activation by switching visual status indicators (such as the terminal interface theme color).

[0044] Step S2. In the work mode, the work group call is initiated directly in response to the PTT button (“Push-to-Talk”, i.e., one-touch call button) command, or the new work group call is switched and specified through navigation keys (such as directional keys) or touch operation;

[0045] Step S3. After the terminal joins the work group call, start a timer to trigger a custom voice broadcast in a loop to remind the user to seize the uplink channel;

[0046] Step S4. After successfully detecting uplink channel preemption, stop the current voice broadcast; when the current timer expires, restart the timer to enter the next voice reminder cycle;

[0047] Step S5. In response to the exit operation mode command, automatically restore the activation status of all group calls and the original visual status indicators (such as the original theme color of the terminal interface).

[0048] In some embodiments, in step S1: the deactivation operation causes the terminal to only respond to job group calls and cannot initiate non-job group calls; in step S5, the restored activation state allows the terminal to initiate and receive all previously activated group calls.

[0049] In some embodiments, step S2 includes: directly initiating a preset job group call in response to a PTT button command; and traversing the group call list using the arrow keys in the standby interface to update the selected group call to the current job group call in real time.

[0050] In some embodiments, in step S3: the content and period of the voice broadcast can be pre-configured by the user; the timer is automatically initialized and started when the job group call is established.

[0051] In some embodiments, step S4 includes: the voice broadcast continues in a loop until uplink preemption is detected; the timer restarts to trigger the next voice reminder cycle.

[0052] In some embodiments, the method further includes: the name of the work group call can be customized and edited, and the customized name is displayed in real time on the incoming call interface, the call interface and the communication record.

[0053] In some embodiments, when a user leaves a job group call, the voice broadcast is automatically terminated and the timer is stopped.

[0054] In some embodiments, the method is used for GSM-R handheld terminals and 5G-R mobile terminal devices.

[0055] In some embodiments, in step S1: the switching of the visual status indicator includes switching the terminal interface theme color to the job status indicator color. The theme color switching is used to explicitly distinguish the terminal status in job mode and non-job mode.

[0056] This invention relates to a work mode and joint control reminder method based on the GSM-R network. Leveraging the coverage advantages of the GSM-R network's dedicated network, it employs a unique single-group activation work mode and a periodic voice joint control reminder mechanism. This ensures wide-area communication coverage while significantly reducing network resource consumption and terminal power consumption. Its work mode provides one-click shielding against interference from non-work group calls, and combined with the PTT button for quick group call initiation and the directional key dynamic switching function, it solves the problems of low efficiency and chaotic voice conference information in traditional point-to-point communication. Fixed-period automatic voice reminders effectively avoid human communication oversights. It simultaneously optimizes four dimensions: network coverage reliability, channel resource utilization, operational convenience, and work safety, ultimately achieving low-latency, low-accident-rate engineering construction protection communication.

[0057] The following describes specific embodiments of the present invention.

[0058] See Figure 2 A working mode and joint control reminder method based on GSM-R network mainly includes the following processes:

[0059] (1) When a user starts the job mode and sets up the specified job group call, the terminal will automatically activate other group calls and switch the interface theme color.

[0060] (2) In the work mode, pressing the PTT key can quickly initiate a call to a specified work group.

[0061] (3) In the work mode, you can quickly switch to other group calls by using the up and down keys, making it a new work group call.

[0062] (4) During the work group call communication process, the terminal will remind the user to perform the call uplink preemption operation through automatic voice broadcast at fixed intervals.

[0063] (5) The content and frequency of automatic voice broadcasts can be changed.

[0064] (6) When exiting the operation mode, the terminal will automatically restore the activation status of all group calls and the original theme color of the interface.

[0065] (7) The name of the work group call can be edited and changed, and the custom name will be displayed in incoming calls, calls and communication records.

[0066] This invention includes three core functions: entering / exiting work mode, initiating and switching work group calls, and joint control reminders. After activating work mode, the terminal enters a state where only a single group (work group call) is active, automatically deactivating other groups to avoid interference with the work. During work group call communication, the terminal automatically and cyclically initiates fixed-cycle voice reminders (i.e., joint control reminders) until the user responds and successfully preempts the work group call uplink, at which point the current round of voice reminders ends. The name of the work group call can be customized and is displayed in incoming calls, call logs, and communication records. Simultaneously, work group calls can be quickly initiated with a single click via the PTT button and can also be quickly switched using the up and down keys in the standby interface.

[0067] The following provides a detailed explanation of how these three core functions are implemented:

[0068] I. Entering / Exiting Work Mode

[0069] In standby mode, you can quickly enter and exit the work mode using shortcut keys.

[0070] (1) When entering the work mode, the terminal will automatically deactivate other groups and retain only the work group call; the terminal will neither respond to the deactivated group call nor initiate the group call through the terminal.

[0071] (2) After entering the work mode, the theme color of the terminal interface will be changed automatically to distinguish the non-work mode status in an explicit way.

[0072] (3) When exiting the operation mode, the terminal will automatically restore the activation status of all groups, enabling it to initiate and receive calls from all originally active groups, while restoring the original theme color of the interface.

[0073] II. Initiating a work group call

[0074] When the terminal is in standby mode, users can quickly initiate a job group call by pressing the PTT button, or by entering a number or by using a menu such as the address book.

[0075] III. Joint Prevention and Control Reminder

[0076] After entering the work group call, the terminal will automatically and periodically broadcast voice prompts according to the user's set time to remind the user to preempt the uplink; once the uplink is successfully preempted, the current round of voice prompts ends.

[0077] Key design features of embodiments of the present invention include:

[0078] 1) When entering the work mode, automatically deactivate other group calls except for the work group call.

[0079] 2) The terminal interface theme color will be automatically changed after entering the operation mode, and will be restored to the original theme color after exiting the operation mode.

[0080] 3) In work mode, pressing the PTT button can quickly initiate a call to a specified work group.

[0081] 4) In work mode, you can quickly switch to other group calls using the up and down keys to create a new work group call.

[0082] 5) During the work group call communication process, remind users to preempt the call uplink by periodically broadcasting automatic voice messages.

[0083] 6) When exiting the work mode, automatically restore the activation status of all group calls.

[0084] 7) The work group call has a name customization function, which can replace the original three-digit GSM-R group call number with more meaningful Chinese characters, and display it in incoming calls, calls and communication records.

[0085] like Figure 2 The diagram illustrates the complete process of a specific embodiment. Starting from the non-job mode state, if an instruction to enter job mode is received, the non-job group call deactivation and theme color switching operations are performed, entering the job mode active state. In this state, if a job group call is initiated or joined, a user-defined voice broadcast timer is started. When the timer expires, a voice broadcast reminder is triggered repeatedly to preempt uplink. If an exit job group call instruction is detected during this period, the broadcast immediately stops. When an exit job mode instruction is received, the process terminates by restoring all group call active states and the original theme color, ensuring that the timer and voice broadcast function are stopped synchronously when an exit instruction is triggered at any operation stage.

[0086] The method of the present invention is applicable to GSM-R handheld terminal devices, and is also applicable to other mobile terminal devices such as 5G-R.

[0087] In summary, compared with the prior art, the core technical advantages of this invention are as follows: by activating the work mode, non-work group calls can be automatically deactivated to avoid interference with the work; work group calls can be quickly initiated via the PTT key and can also be quickly switched using the navigation key; during work group call communication, the system can periodically and automatically broadcast voice reminders to the user to preempt the uplink call; the work group call name can be customized and displayed in multiple locations; and the system can automatically switch and restore the visual status indicator. Furthermore, when exiting the work mode, the activation status of all group calls can be restored. The operation is convenient and the functions are practical, effectively improving the communication efficiency and user experience of GSM-R network-based operations.
