Description

Technical Field

[0001] The present invention relates to the technical field of railway 5G communication station platform terminals, and in particular to a method for implementing a 5G-based MCX and 450M fusion station platform terminal. Background Art

[0002] At present, the domestic local conventional railway transportation system adopts the traditional 450M analog wireless train modulation system, which has begun to show deficiencies in centralized dispatching, reliability, safety, parallel dispatching and data transmission capabilities, and has become a bottleneck affecting railway operation efficiency and business expansion. In addition, the technical foundation of the 450M traditional analog train modulation system, especially the standard, is backward, the functions are isolated, the function expansion is very difficult, the call range is limited, and the 450M frequency band used by the analog wireless train modulation system has exceeded its use period and will be taken back by the Ministry of Industry and Information Technology. However, the communication method used by most local railways is still the 450M analog wireless train modulation system. Therefore, it is unrealistic to completely abandon the 450M analog wireless train modulation system, and it is urgent to upgrade the analog wireless system used by the existing railways in my country.

[0003] At present, the country is vigorously developing 5G technology. Due to the continuous development and popularization of 5G technology and as a new generation of mobile communication technology, it has the characteristics of high speed, low latency and wide coverage, which greatly reduces network latency, achieves faster network response speed, has larger bandwidth, and can process more data and information at the same time. With the popularization of 5G technology, all walks of life can accelerate the process of digital transformation. By integrating with 5G, traditional industries can achieve digital upgrades and enhance their competitiveness. Summary of the invention

[0004] In order to solve the problems of backward 450M railway communication standards, difficulty in function expansion, limited call range and low data transmission reliability, the present invention aims to provide a method for implementing a 5G-based MCX and 450M fusion platform terminal on the premise of taking the traditional 450M analog wireless train dispatching system as an alternative.

[0005] The station terminal integrates the relevant station terminal functions of the 5G broadband dispatching communication system and the existing traditional 450M analog dispatching system, connects the traditional 450M analog dispatching system to the 5G broadband dispatching communication system, and realizes the ability to call locomotive radio stations under the 5G network and locomotive radio stations within the 450M wireless coverage range by operating the terminal on the same interface. It also has the function of being called by locomotive radio stations of different modes at the same time.

[0006] The technical solution adopted by the present invention is: a method for implementing a 5G-based MCX and 450M integrated station platform terminal, the steps are as follows: the station platform equipment and the MCX dispatching screen communicate through the 5G network, the railway dedicated line network is provided to the MCX server and the MCX dispatching screen, the MCX dispatching screen logs in, and the data in the MCX server is transmitted to the MCX dispatching screen through the network; After logging in to the MCX dispatch screen, the main interface displays online. At this time, set the station platform number and called number on the MCX dispatch screen, set the transmission channel of the station platform equipment to 5G call mode, and set the train number and locomotive number of the station platform equipment. The MCX dispatch screen calls the station platform equipment by entering the train number or locomotive number. Conversely, the station platform equipment calls the MCX dispatch screen by entering the station platform number or called number of the MCX dispatch screen. The platform equipment and the MCX dispatching screen conduct 450M calls. The MCX dispatching screen and the 450M simulated platform are connected through network cables and switches. The 450M simulated platform accesses the MCX system through the network provided by the railway dedicated line network. The 450M simulated platform converts voice data into specified data frames and sends them to the MCX system. The MCX system processes and sends them to the 450M simulated platform. The 450M simulated platform sends the voice data collected from the MCX system to the platform equipment, thereby realizing the voice call from the MCX dispatching screen to the platform equipment; conversely, when the platform equipment calls the MCX dispatching screen, the MCX system converts the data frames and digital audio of the data called out by the platform equipment into M4301 signaling and analog audio and sends them to the 450M simulated platform. The 450M simulated platform processes the data and sends it to the MCX dispatching screen. At this time, the MCX dispatching screen receives the voice call from the platform equipment.

[0007] The MCX dispatching large screen interface includes the station platform main interface, 5G call interface and 450M call control frame; The main interface of the station platform consists of system status, program login status, call records, function area, call control, and configuration area; The 5G call interface consists of a single call button, a group call button, a contact list, and a dial pad; The 450M call control frame has the functions of hiding, basic call area, and extended call display area; The main interface of the station displays the station number, station name, year, month, day and time, with the time accurate to the second. When online, the program displays the green word "Login", and when offline, it displays the red word "Offline". The call log stores the date, call duration and call number of each call. The volume area can be expanded to adjust the call volume and media volume. The station number and station name can be modified after the configuration area is expanded. The single call key in the 5G interface is used to call locomotives and stations along the line with a single key. The single call key calls the locomotive by train number in general mainline scenarios, or calls the locomotive by locomotive number in general non-mainline scenarios. The group call key is used to call the dispatching screens and platform equipment of other stations at the same time; The address book can add the locomotive number and train number to be called in the single call key. After adding, click the add single call key, and the single call key interface will call the newly added locomotive number and train number with one click; The dial plate is manually input according to the locomotive number type or train number type to make a call; The 450M call control box has the functions of hiding, basic call area, and extended call display area. When the 5G signal along the railway is unstable or the railway needs to switch to 450M call, select the 450M call interface. When the 450M call control box is expanded, four call options, namely "Plain Driver", "Tunnel Locomotive", "Station" and "Dispatching", are displayed. When calling the Plain Driver, Tunnel Locomotive, Station and Dispatching, you need to press the off-hook key first, and then press the corresponding function to call. After calling out, wait for the ringback and press the PTT key to speak. To prevent the PTT key from being accidentally touched, causing the other end of the call to be unable to speak, the lock picture key is in the off state by default. At this time, the PTT lock function is enabled. When the lock picture key is on, the PTT lock function is turned off.

[0008] A 5G-based MCX and 450M integrated platform terminal, including a railway dedicated line network, an MCX server, an MCX dispatching screen, a switch, a 450M simulated platform, and platform equipment; The station platform equipment is bidirectionally connected to the 450M simulated station platform and the MCX dispatching screen respectively, the 450M simulated station platform is bidirectionally connected to the switch, the switch is bidirectionally connected to the MCX dispatching screen, the MCX server is unidirectionally connected to the MCX dispatching screen and the station platform equipment respectively, and the railway dedicated line network is connected to the MCX dispatching screen and the station platform equipment respectively; The railway dedicated line network is used to provide the network to the MCX server and the MCX dispatching large screen; The station platform equipment is used for 450M wireless calls, displays received information and sent data through the MMI, and conducts voice calls through the transmitter and receiver; The switch is used to identify the received data and forward it to the 450M simulation station platform; The MCX dispatching large screen is used for 5G calls and 450M analog train dispatching calls; The 450M analog station platform is used to connect the analog-to-digital conversion unit to the MCX system; The MCX server is used to provide MCX data.

[0009] The beneficial effects of the present invention are as follows: the fusion platform terminal has the advantages of multi-mode fusion and user-friendly interface. The 5G call has a one-key call function, which can call the locomotive by train number or locomotive number. The 450M call control frame has the functions of hiding, basic call area, and extended call display area.

[0010] In view of the problems that 450M wireless train modulation has begun to show deficiencies in many aspects such as backward technical standards, difficulty in isolated function expansion, co-channel interference reliability, security, parallel scheduling and data transmission capabilities, as well as the fact that the 450M communication frequency band will be withdrawn, the present invention promotes 5G applications and integrates video call functions, provides more comprehensive and powerful communication capabilities for vehicle terminals, greatly improves the safety and efficiency of vehicle operation, and provides strong support for the development of intelligent transportation and Internet of Vehicles.

[0011] Since most local railways still use 450M analog wireless train dispatching systems, 450M analog wireless communication needs to be retained. The present invention integrates 5G technology with traditional 450M analog wireless train dispatching, and utilizes the advantages of low latency, high speed, and wide connection of 5G communication itself, which greatly reduces network latency, achieves faster network response speed, and can process more data and information at the same time, providing station platform terminals with more powerful and reliable communication capabilities. When 5G communication is not used, the retained 450M wireless train dispatching can still be used for communication.

[0012] Through the 5G network, station platform terminals can transmit high-definition video and audio data in real time, support remote real-time video calls and low-latency voice calls, so that the integrated station platform terminals can support video and voice calls between drivers and the command center; this function not only improves the convenience of communications between trains and command centers, but also provides strong support for collaborative operations and emergency command between vehicles.

DETAILED DESCRIPTION

[0014] In order to understand the present invention more clearly, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0015] like Figure 1As shown, a 5G-based MCX and 450M integrated platform terminal includes a railway dedicated line network, an MCX server, an MCX dispatching screen, a switch, a 450M simulated platform, and platform equipment.

[0016] like Figure 2 As shown, the 450M simulated station platform is an M4301 station platform, including an analog-to-digital conversion unit, an analog train adjustment unit, a switching unit, a power switch unit and a test unit; The analog-to-digital conversion unit is responsible for converting the signaling and analog audio of the simulated station platform into specified data frames and sending them to the MCX system. The collected data will then be sent to the channel machine in the CIR host. The channel machine will display the received data through the MMI after data processing. The simulated train modulation unit is used to configure the simulated train modulation frequency. The display unit is used for the transmission and display of the train number. The test unit is used for the dispatch command transfer display. The power switch unit is used to provide power to the simulated station platform.

[0017] like Figure 3 As shown, the platform equipment includes a CIR host, an MMI, a handset, and a printing terminal; the CIR host is used to receive, send, and integrate data; the MMI is used to realize human-computer information interaction; the handset is used to act as a microphone for voice calls; and the printing terminal is used to print out paper dispatch commands under the control of the MMI.

[0018] like Figure 4 As shown, the MCX dispatching screen includes a gooseneck microphone, a screen and a handle; the gooseneck microphone is used to receive voice; The large screen is used to display interface information and conduct human-computer information interaction; the handle is used for voice calls.

[0019] The process of 450M communication is that the MCX dispatching screen and the 450M simulated station platform are connected through network cables and switches. The analog-to-digital conversion unit of the 450M simulated station platform is connected to the MCX system. The analog-to-digital conversion unit is responsible for converting the signaling and analog audio of the simulated station platform into specified data frames and sending them to the MCX system. After that, the collected data is sent to the channel machine in the CIR host. After data processing, the channel machine displays the received data through the MMI, thereby realizing the voice call and video call from the MCX dispatching screen to the CIR host. Conversely, when the CIR host calls the MCX dispatching screen, the MCX system converts the data frame and digital audio of the outgoing data into M4301 signaling and analog audio through the channel machine of the CIR host and sends them to the simulated station platform. After data processing, the simulated station platform sends them to the MCX dispatching screen. At this time, the MCX dispatching screen can display the voice call from the CIR host. The digital audio in the 450M communication is transmitted using the RTP protocol, and the analog-to-digital conversion unit is transmitted using the UDP protocol. In order to extract the data frame content, a frame header mark is added to the front end of the data frame during transmission to facilitate identification. The frame header mark is ABCD3333H. The process of 5G communication is that both the MCX server and the MCX dispatching screen provide the network through the IoT card. The MCX server and the MCX dispatching screen set their own required IP addresses. It is necessary to ensure that the IP address set by the MCX dispatching screen is in the same IP segment as the MCX server. Set the station platform number and the called number on the MCX dispatching screen, set the transmission channel of the station equipment to 5G call mode, and set the train number and locomotive number of the station platform equipment. After that, the MCX dispatching screen can call the station platform equipment by entering the train number or locomotive number. Conversely, the station platform equipment can call the MCX dispatching screen by entering the station platform number or called number of the MCX dispatching screen.

[0020] The main interface of the MCX dispatch screen includes the station platform main interface, 5G call interface, and 450M call control box. The 450M call control frame consists of system status, program login status, call records, function area, call control, and configuration area; The 5G call interface consists of the single call button, group call button, address book and dial pad; The single call button is used to call locomotives and stations along the line with a single button. It has a one-button calling function. In general mainline scenarios, the locomotive is called by the train number, and in general non-mainline scenarios, the locomotive is called by the locomotive number; The group call key is used to call the dispatching screens and platform equipment at other stations at the same time; The address book is used to add the locomotive number and train number to be called in the single call key. After adding, click the add single call key. The single call key interface can call the newly added locomotive number and train number with one click; The dial pad is used to manually input calls according to the locomotive number type or train number type.

[0021] The 450M call control frame has the functions of hiding, basic call area, and extended call display area; The hidden function can hide the four call options of "Plain Driver", "Tunnel Locomotive", "Station" and "Dispatch"; In the basic conversation area, you need to press the off-hook button first, then press the corresponding function to call, wait for the ringback after calling, and press the PTT button to speak; The extended call display area can show four call options: "Plain Driver", "Tunnel Locomotive", "Station" and "Dispatching".

[0022] According to specific needs or the MCX / 450M transition stage selection interface, in the 450M call interface, users need to call the plain driver, tunnel locomotive, station, etc. Please pick up the phone first, then press the corresponding function to call. After the call is made, wait for the ringback and press PTT to speak. The lock icon above can be changed by clicking on it. When it is locked, the PTT lock function is enabled. When the lock icon is unlocked, the PTT lock function is disabled. When the fusion station is idle, pay attention to the hardware handle being on-hook. Touch the off-hook and PTT button to be on-hook or lifted. The hardware handle is used to switch between microphones. When the handset is off-hook, the microphone and receiver of the handle are valid. When the handset is on-hook, the external microphone and speaker are valid. The volume of the fusion station is adjusted to the appropriate volume as needed. Enter the volume setting interface through the gray button at the bottom of the interface. When using the fusion station, pay attention to whether the login status of the MCX main interface is normal and whether the 450M station terminal is online. Press and hold the button below the handle for about 3 seconds to select shutdown and restart operations, and short press to start the machine.

[0023] Example 1, a method for implementing a 5G-based MCX and 450M integrated station platform terminal, When the platform equipment and the dispatching screen communicate through the 5G network, the railway dedicated network is first provided to the MCX server and the MCX dispatching screen. At this time, the MCX server and the MCX dispatching screen both have the network. Then the MCX server and the MCX dispatching screen set their respective required IP addresses, i.e. 10.64.xx. The IP address set for the MCX dispatching screen needs to be in the same IP segment as the MCX server. At this time, the MCX dispatching screen can be logged in, and the data in the MCX server is transmitted to the MCX screen through the network; After logging in to the MCX dispatch screen, the main interface displays online. At this time, set the station number 79110xxx and the called number 14889199xxx on the MCX dispatch screen, set the transmission channel of the station equipment to 5G call mode, and set the train number K1234 and locomotive number SS4-xxxx of the station equipment. Then, the MCX dispatch screen calls the station equipment by entering the train number or locomotive number. After the MCX dispatch screen dials the call, the train number or locomotive number of the incoming call will be displayed on the MMI of the station equipment, the handset receives the incoming call ring, and the driver uses the handset to confirm the call reception and prints out the paper dispatch command with the printing terminal. Conversely, the station equipment enters the station number or called number of the MCX dispatch screen through the MMI to call the MCX dispatch screen.

[0024] When the station platform equipment and the dispatching screen are conducting a 450M call, the MCX dispatching screen and the 450M simulated station platform are both connected to the switch. The switch identifies the received data and forwards it to the 450M simulated station platform. The power switch unit provides power to the simulated station platform. The analog-to-digital conversion unit in the simulated station platform is connected to the MCX system through the network provided by the railway dedicated line network. The analog train modulation unit of the 450M simulated station platform configures the analog train modulation frequency. The analog-to-digital conversion unit is responsible for converting the signaling and analog audio of the simulated station platform into specified data frames and sending them to the MCX system. Then, the collected data is sent to the channel machine in the CIR host. After data processing, the channel machine displays the received data through the MMI, thereby realizing the voice call from the MCX dispatching screen to the CIR host; conversely, when the CIR host calls the MCX dispatching screen, the MCX system converts the data frame and digital audio of the outgoing data into M4301 signaling and analog audio through the channel machine of the CIR host and sends it to the 450M simulated station platform. After data processing, the 450M simulated station platform sends it to the MCX dispatching screen. At this time, the MCX dispatching screen displays the voice call from the CIR host. The MCX dispatching screen calls through the gooseneck microphone. When the handle is picked up, the gooseneck microphone calls the valid display unit for the train number transmission display, and the test unit is used for the dispatching command transfer display.
