[0029] The technical solutions of the present application are described below through specific embodiments.

[0030] Referring to Figure 1 , a schematic diagram of a vehicle-mounted converged communication method provided by an embodiment of the present application is shown.

The button panel provides redundant operation for the LCD touch display screen and improves the availability of the device.

[0039] As shown in FIG. 1, the vehicle-mounted integrated communication machine includes a main control module, a power conversion module, and a human-machine interface module. Figure 4

[0040] The main control module includes a central processing unit, a digital-to-analog converter, a sound card module, a power amplifier, an audio amplifier, and the like.

[0054] The camera is responsible for video monitoring in the vehicle closed-circuit television monitoring system and collects real-time videos of monitored parts such as passenger compartments, driver's rooms, tracks and pantographs.

[0055] The vehicle switch is a train Ethernet connection device and realizes network connection of system terminal devices.

[0056] In this embodiment, the vehicle integrated communication machine can be applied to a vehicle station, as shown in FIG. Figure 1 The method can specifically include the following steps.

[0057] In step 101, when powered on, the main connection and the standby connection are respectively established according to the driver's rooms where the two hosts of the vehicle station are located.

[0058] Generally, the hosts of the vehicle station are deployed in two trailer cars with driver's rooms in the rail transit train.

[0059] When the system is powered on, each vehicle integrated communication machine can identify the driver's rooms where the two hosts of the vehicle station are located, and then the main connection and the standby connection are respectively established according to the driver's rooms where the two hosts of the vehicle station are located, that is, the main connection is established with one of the two hosts of the vehicle station to bear the main service transmission and guarantee the service performance, and the standby connection is established with the other host of the vehicle station as a fault redundancy backup to realize load sharing and provide disaster recovery security.

[0060] The master connection and the standby connection are switched between the two hosts of the vehicle station according to the first working state, so that the normal operation of the vehicle station is ensured.

[0061] In a specific implementation, the current vehicle-mounted integrated communication machine can mark the trailer in the cab where the current vehicle-mounted integrated communication machine is located as a local trailer, and mark the trailer in the cab where another vehicle-mounted integrated communication machine is located as a remote trailer.

[0062] If the host of the vehicle station is in the cab of the local trailer, the current vehicle-mounted integrated communication machine establishes a master connection with the host of the vehicle station.

[0063] If the host of the vehicle station is in the cab of the remote trailer, the current vehicle-mounted integrated communication machine establishes a standby connection with the host of the vehicle station.

[0064] Step 102, detecting a first working state of two hosts of a vehicle station.

[0065] In the embodiment, the current vehicle-mounted integrated communication machine can detect the first working state of the two hosts of the vehicle station in real time by using a heartbeat, a probe, or the like every first detection period.

[0066] The first detection period can be configured, such as 1s-60s, and the first working state includes normal and fault.

[0067] Step 103, switching a master connection and a standby connection between the hosts of the vehicle station according to the first working state.

[0068] In the embodiment, the current vehicle-mounted integrated communication machine switches the master connection and the standby connection between the two hosts of the vehicle station according to the first working state, so as to ensure the normal operation of the vehicle station.

[0069] In a specific implementation, for the current vehicle-mounted integrated communication machine, if the first working state of the host of the vehicle station in the cab of the local trailer is normal, and the first working state of the host of the vehicle station in the cab of the remote trailer is normal, the master connection between the current vehicle-mounted integrated communication machine and the host of the vehicle station in the cab of the local trailer is maintained unchanged, and the standby connection between the current vehicle-mounted integrated communication machine and the host of the vehicle station in the cab of the remote trailer is maintained unchanged.

[0070] For the current vehicle-mounted integrated communication machine, if the first working state of the host of the vehicle station in the cab of the local trailer is fault, and the first working state of the host of the vehicle station in the cab of the remote trailer is normal, the master connection between the current vehicle-mounted integrated communication machine and the host of the vehicle station in the cab of the local trailer is disconnected, and the standby connection between the current vehicle-mounted integrated communication machine and the host of the vehicle station in the cab of the remote trailer is converted into a master connection, so as to ensure that the communication of the vehicle station is not affected.

[0071] At this time, the host of the vehicle-mounted station in the driver's cab of the other trailer establishes a main connection with both vehicle-mounted converged communication units. Under these circumstances, the operation instructions are sent to the host of the vehicle-mounted station in the driver's cab of the other trailer. The priority of the operation instructions of the two vehicle-mounted converged communication units is determined according to the priority order of the operation instructions of the two vehicle-mounted converged communication units. That is, the host of the vehicle-mounted station in the driver's cab of the other trailer can use FIFO (First In First Out) queues or other methods to cache the operation instructions of the two vehicle-mounted converged communication units in chronological order and execute the operation instructions of the two vehicle-mounted converged communication units in chronological order.

[0072] For the current vehicle-mounted converged communication unit, if the first working state of the host of the vehicle-mounted unit in the driver's cab of the local trailer is normal (i.e., fault recovery), and the first working state of the host of the vehicle-mounted unit in the driver's cab of the remote trailer is normal or faulty, then the main connection with the host of the vehicle-mounted unit in the driver's cab of the local trailer is re-established, and the connection with the host of the vehicle-mounted unit in the driver's cab of the remote trailer is switched from the main connection to the backup connection.

[0073] In this embodiment, an IP-based in-vehicle converged communication unit is deployed in two trailers with driver's cabs in a rail transit train. This unit serves as the human-machine interface for the in-vehicle radio, the in-vehicle passenger information system, and the in-vehicle closed-circuit television monitoring system. By providing a single device that simultaneously provides the human-machine interface for these systems, the number of devices and cables is reduced, minimizing the space occupied by the driver's console and simplifying wiring. Furthermore, the hardware cost and energy consumption of this single device are low, effectively improving the efficiency of providing the human-machine interface for the in-vehicle radio, passenger information system, and closed-circuit television monitoring system.

[0074] A primary connection and a backup connection are established between the vehicle-mounted unit's main unit and the main unit located in the driver's cab, respectively. The first operating status of the two main units of the vehicle-mounted unit is detected. Based on the first operating status, the primary connection and the backup connection are switched between the two main units of the vehicle-mounted unit. This embodiment uses different control strategies to connect the main units of the vehicle-mounted unit according to the location of the deployed main unit and the status of the main unit, which can improve the availability of the vehicle-mounted unit.

[0075] Reference Figure 5 The diagram illustrates another in-vehicle converged communication method provided by an embodiment of the present invention, which may specifically include the following steps:

[0076] Step 501: Detect the activation status of the two driver's cabs.

[0077] When the system is powered on, each vehicle-mounted converged communication unit can identify the activation status of the two driver's cabs.

[0078] The activation status includes activated and inactive.

[0079] Step 502: Based on the activation status, set the two main units of the vehicle passenger information system as the main controller and the auxiliary controller, respectively.

[0080] Each vehicle-mounted converged communication unit can set the two main units of the vehicle passenger information system as master and slave controllers respectively, based on the activation status of the two driver's cabs. That is, one of the main units of the vehicle passenger information system is set as the master controller to execute the core control logic, manage and monitor the overall status, realize resource scheduling and priority allocation, and interact with and receive instructions. The other main unit of the vehicle passenger information system is set as the slave controller to realize redundancy backup and fault takeover, auxiliary load sharing, fault detection and collaborative diagnosis, local control and emergency response.

[0081] By designing a primary control unit and a secondary control unit for primary decision-making and secondary backup / assistance, the reliability, availability, and fault tolerance of the control system are improved, preventing system paralysis due to the failure of a single control unit.

[0082] In practical implementation, for the current in-vehicle converged communication unit, if the activation status of the driver's cabs of both trailers is inactive, then the default will be one of the trailers (e.g., Figure 2 In the driver's cab of Tc1, the host of the onboard passenger information system is set as the master controller, and the default other trailer (such as...) is set as the master controller. Figure 2 In Tc2, the host of the on-board passenger information system is set as the secondary controller.

[0083] If one driver's cab is activated and the other is deactivated, the host of the onboard passenger information system in the trailer with the activated driver's cab is set as the master controller, and the host of the onboard passenger information system in the trailer with the deactivated driver's cab is set as the slave controller.

[0084] Step 503: Detect the second working status of the two main units of the vehicle passenger information system.

[0085] In this embodiment, the current vehicle-mounted converged communication unit can use heartbeat, probe and other methods to detect the second working status of the two main units of the vehicle passenger information system in real time at preset second detection intervals.

[0086] The second detection cycle is configurable, such as 10ms to 1000ms, and the second working state includes normal and fault states.

[0087] Furthermore, for the same host of the vehicle passenger information system, if its second operating state is detected as faulty in N consecutive second detection cycles, the second operating state of that host of the vehicle passenger information system is determined to be faulty.

[0088] Where N is a positive integer, which is configurable and ranges from 1 to 10, with 4 being an optional value.

[0089] Step 504: Switch between main control and auxiliary control between the two main units of the vehicle passenger information system according to the second working state.

[0090] In this embodiment, the current vehicle-mounted converged communication unit switches between the main control and the secondary control between the two main units of the vehicle-mounted passenger information system according to the second working state, so as to ensure the normal operation of the vehicle-mounted passenger information system.

[0091] In a specific implementation, if the second working state of the host of the vehicle passenger information system currently acting as the master controller is normal, and the second working state of the host of the vehicle passenger information system currently acting as the slave controller is normal, then the host of the vehicle passenger information system currently acting as the master controller remains unchanged, and the host of the vehicle passenger information system currently acting as the slave controller remains unchanged.

[0092] For the current in-vehicle converged communication unit, if the second working state of the host of the in-vehicle passenger information system, which is currently the main controller, is normal, and the second working state of the host of the in-vehicle passenger information system, which is currently the secondary controller, is faulty, then the host of the in-vehicle passenger information system, which is currently the main controller, remains unchanged, and the host of the in-vehicle passenger information system, which is currently the secondary controller, remains unchanged.

[0093] For the current in-vehicle converged communication unit, if the second working state of the host of the in-vehicle passenger information system, which is currently the master controller, is faulty, and the second working state of the host of the in-vehicle passenger information system, which is currently the slave controller, is normal, then the host of the in-vehicle passenger information system, which is currently the master controller, is set as the slave controller, and the host of the in-vehicle passenger information system, which is currently the slave controller, is temporarily set as the master controller.

[0094] Furthermore, if the main unit of the on-board passenger information system, which is currently acting as the secondary controller, recovers from a malfunction and returns to normal, the primary and secondary controllers will remain unchanged until the system is powered off and restarted again, or the activation status of the driver's cab changes.

[0095] For example, such as Figure 2 As shown in the table below, the main / backup connection relationship and main / supplementary control relationship between the vehicle-mounted converged communication unit and the two main units of the vehicle-mounted radio are as follows:

[0096]

[0097] In this embodiment, the activation status of the two driver cabs is detected; based on the activation status, the two main units of the in-vehicle passenger information system are respectively set as the main controller and the auxiliary controller; the second operating status of the two main units of the in-vehicle passenger information system is detected; and based on the second operating status, the main controller and auxiliary controller are switched between the two main units of the in-vehicle passenger information system. This embodiment uses different control strategies to set the main and auxiliary controllers according to the activation status of the driver cabs and the status of the main units of the in-vehicle passenger information system, which can improve the availability of the in-vehicle passenger information system.

[0098] Reference Figure 6 The diagram illustrates another vehicle-mounted converged communication method provided by an embodiment of the present invention, which may specifically include the following steps:

[0099] Step 601: Assign the first sound card to the vehicle radio and the second sound card to the vehicle passenger information system.

[0100] To ensure that the voice communication between the vehicle-mounted radio and the passenger information system remains independent, the passenger information system includes two independent sound cards and two sets of speakers and microphones. For ease of distinction, the two independent sound cards are referred to as the first sound card and the second sound card. The first sound card is used to independently drive one set of speakers and microphones (such as the speakers and microphones located on the right side of the vehicle-mounted radio), and the second sound card is used to independently drive another set of speakers and microphones (such as the speakers and microphones located on the left side of the vehicle-mounted radio). This ensures that the voice communication between the vehicle-mounted radio and the passenger information system remains independent and can still operate independently.

[0101] When the system is powered on, the first sound card can be assigned to the vehicle radio by default, and the second sound card can be assigned to the vehicle passenger information system by default.

[0102] Step 602: When the vehicle-mounted radio is idle and the vehicle passenger information system is connected to two voice communications, switch the first sound card from the vehicle-mounted radio to the vehicle passenger information system so that the vehicle passenger information system can use the first sound card and the second sound card to conduct two voice communications at the same time.

[0103] When the vehicle-mounted radio is idle and the vehicle passenger information system is connected to two voice communications, the first sound card can be switched from the vehicle-mounted radio to the vehicle passenger information system. At this time, the vehicle passenger information system simultaneously allocates the first sound card and the second sound card. The vehicle passenger information system simultaneously uses the first sound card (to drive the speaker and microphone of the vehicle-mounted radio) for one voice communication and uses the second sound card (to drive its own speaker and microphone) for the other voice communication.

[0104] For example, voice communication in an in-vehicle passenger information system typically includes human broadcasts, driver intercom, and passenger emergency intercom, and the modes of simultaneous voice communication are shown in the table below:

[0105]

[0106] Step 603: When the vehicle-mounted radio is connected to voice communication, suspend the voice communication that is occupying the first sound card in the vehicle passenger information system and switch the first sound card from the vehicle passenger information system to the vehicle-mounted radio.

[0107] When the in-vehicle passenger information system is using both the first and second sound cards for two voice communications, if a voice communication is connected to the vehicle-mounted station (i.e., a call is being made), one of the voice communications in the in-vehicle passenger information system is suspended, and the first sound card is switched from the in-vehicle passenger information system to the vehicle-mounted station. The vehicle-mounted station can then use the first sound card (which drives its own speaker and microphone) for voice communication normally.

[0108] In this embodiment, a first sound card is assigned to the vehicle-mounted radio, and a second sound card is assigned to the vehicle-mounted passenger information system. When the vehicle-mounted radio is idle and the vehicle-mounted passenger information system is receiving two voice communications, the first sound card is switched from the vehicle-mounted radio to the vehicle-mounted passenger information system, allowing the vehicle-mounted passenger information system to simultaneously use both the first and second sound cards for two voice communications. When the vehicle-mounted radio is receiving a voice communication, the voice communication in the vehicle-mounted passenger information system that is using the first sound card is suspended, and the first sound card is switched from the vehicle-mounted passenger information system to the vehicle-mounted radio. This embodiment uses a dual-sound-card design, which improves the availability of the vehicle-mounted passenger information system while maintaining the independence of the voice communication between the vehicle-mounted radio and the vehicle-mounted passenger information system.

[0109] It should be noted that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0110] Reference Figure 7 The diagram illustrates a vehicle-mounted converged communication device according to an embodiment of the present invention. The IP-based vehicle-mounted converged communication unit is deployed in two trailers with driver's cabs in a rail transit train. The vehicle-mounted converged communication unit serves as the human-machine interface for a vehicle-mounted radio, a vehicle-mounted passenger information system, and a vehicle-mounted closed-circuit television monitoring system. The device applied to the vehicle-mounted converged communication unit may specifically include the following modules:

[0111] The connection establishment module 701 is used to establish a main connection and a backup connection between the driver's cab where the main unit of the vehicle-mounted radio is located and the main unit of the vehicle-mounted radio, respectively.

[0112] The first working status detection module 702 is used to detect the first working status of the two main units of the vehicle-mounted radio.

[0113] The connection switching module 703 is used to switch the main connection and the backup connection between the two hosts of the vehicle-mounted radio according to the first working state.

[0114] In one embodiment of the present invention, the connection establishment module 701 includes:

[0115] The main connection establishment module is used to establish a main connection with the main unit of the vehicle-mounted radio if the main unit of the vehicle-mounted radio is located in the driver's cab of the trailer at this end.

[0116] A backup connection establishment module is used to establish a backup connection with the main unit of the vehicle-mounted radio if the main unit of the vehicle-mounted radio is located in the driver's cab of the trailer on the other end.

[0117] In one embodiment of the present invention, the connection switching module 703 includes:
