[0041] As Figure 1 shown, an alarm simulation system based on a real-time message bus includes a command module, a signal simulator, an alarm simulator, an intelligent operation and maintenance module, a hardware module, and a real-time message bus. The command module is communicatively connected to the signal simulator. The signal simulator is communicatively connected to the alarm simulator through the real-time message bus. The alarm simulator is communicatively connected to the intelligent operation and maintenance module and the hardware module respectively through the real-time message bus.

[0042] In the command module, a fault command is edited according to the fault to be simulated and sent to the signal simulator. After receiving the fault command, the signal simulator parses it and sets the corresponding device to a fault. At the same time, fault information is generated according to the parsed information and sent to the alarm simulator. The alarm simulator generates alarm information according to the fault information and sends it to the intelligent operation and maintenance module and the hardware module respectively. The intelligent operation and maintenance module and the hardware module generate alarms synchronously.

[0043] The hardware module includes an indicator light, which extinguishes or flashes according to the alarm information.

[0044] In this embodiment, an autonomous and controllable real-time message bus technology is adopted in the system. This technology integrates the characteristics of object-oriented programming and is implemented through a reliable TCP / IP communication middleware. The real-time message bus supports a streaming network communication mode, ensuring the continuity and stability of data transmission. The bus is configured during the system design phase, and all nodes within the entire system, whether they are clusters or individual workstations, follow the same bus settings to ensure consistency and compatibility. The command module edits fault commands, and the specific content includes vehicle coding information, vehicle equipment coding information, and vehicle equipment alarm coding information. The background of the command module parses and processes the edited fault commands and transmits them to the signal simulator according to the agreed data format.

[0045] The signal simulator receives and processes the message information sent by the command, extracts the vehicle information, vehicle equipment information, and fault code information, and sends them to the alarm simulator in the format of a JSON message through the real-time message bus. The alarm simulator processes the received information and sends it to the intelligent operation and maintenance module and the hardware module respectively for synchronous alarm. The hardware module includes an indicator light. When it receives the corresponding fault command, it controls the corresponding indicator light to flash or turn off to indicate the fault location.

[0046] Embodiment 2

[0047] As Figures 2 - 7 shown, a method for an alarm simulation system based on a real-time message bus, the method specifically includes:

[0048] S1. Determine the fault to be simulated in the command module and edit the fault command;

[0049] S2. The command module sends the fault command to the signal simulator;

[0050] S3. The signal simulator parses the received fault command, sets the corresponding device to a fault, generates fault information according to the parsed information, and sends it to the alarm simulator through the real-time message bus;

[0051] S4. The alarm simulator parses the fault information to generate alarm information and sends the information to the intelligent operation and maintenance module through the real-time message bus, and the intelligent operation and maintenance module displays the corresponding alarm content;

[0052] S5. The alarm simulator parses the fault information to generate alarm information and sends it to the hardware module through the real-time message bus, and the hardware module generates the corresponding alarm state.

[0053] Both the fault information and the alarm information are JSON packets.

[0054] The alarm simulator has an alarm information library built-in, and the alarm information library includes a State group structure, an Lru group structure, and an otherEquipment group structure.

[0055] After the alarm simulator parses the corresponding fields from the fault information, it fills them into the State group structure, the Lru group structure, and the otherEquipment group structure. The intelligent operation and maintenance module displays the alarm content based on the field information in the State group structure, the Lru group structure, and the otherEquipment group structure.

[0056] The State group structure includes stateLRUCounter and stateOtherEquipmentCounter.

[0057] The Lru group structure includes lruDefaultCode, lruDefaultContext, LruIndex, and lruState.

[0058] The otherEquipment group structure includes eqtDefaultCode, eqtDefaultContext, eqtIndex, and eqtState.

[0059] After the alarm simulator parses the corresponding fields from the fault information, it forms the received fields into a corresponding message and forwards it to the hardware module through the real-time message bus. The hardware module prompts the corresponding fault status.

[0060] In this embodiment, according to the JSON packet, it is converted into a corresponding message. The message includes the following content:

[0061] {

[0062] "type":0,

[0063] "trainNum":"801",

[0064] "lruState":"1",

[0065] "lruIndex":"1",

[0066] "lruDefaultCode":"1"

[0067] "stateLRUCounter":"0"

[0068] "lruDefaultContext":""

[0069] "CCCORE1":"10"

[0070] "CCCORE2": "10"

[0071] }

[0072] When the value of "type" is 0, it means that this system is an Lru group structure.

[0073] trainNum is the vehicle number, representing 801 vehicle, 802 vehicle, and 803 vehicle.

[0074] lruIndex is the index number of VIOM1CORE1 in the Lru group system.

[0075] lruState represents whether the device is faulty. 0 means normal and 1 means faulty.

[0076] The count value of stateLRUCounter changes from 0 to 65535 and is accumulated when sending a packet of data.

[0077] "lruDefaultContext": ""; 37 bytes, containing detailed information about the train.

[0078] "CCCORE1": "10"; The running time of the first head. 10 means one cycle every 30s, representing a running time of 300 seconds.

[0079] "CCCORE2": "10"; The running time of the second head. 10 means one cycle every 30s, representing a running time of 300 seconds.

[0080] The State group structure describes the next state and the current state of the vehicle-mounted controller. The stateLRUCounter state and the stateOtherEquipmentCounter state values are used to represent the count in the alarm. The Lru group structure is as follows. The data items used are lruDefaultCode, lruDefaultContext, LruIndex, and lruState, which are the alarm code of the lru device, the content on the vehicle during the specific alarm, the name of the specific vehicle-mounted device, and the specific alarm type respectively. The otherEquipment group structure is as follows. The data items used are eqtDefaultCode, eqtDefaultContext, eqtIndex, and eqtState, which are the alarm code of the auxiliary equipment, the content on the vehicle during the specific alarm, the name of the specific vehicle-mounted device, and the specific alarm type respectively. The auxiliary equipment includes switch equipment, etc.

[0081] The alarm simulator receives the message information sent by the processing signal simulator through the real-time message bus, updates the values in the tablespace corresponding to each vehicle, and forms a Modbus message according to the Modbus protocol format agreed upon with the hardware module, and sends it to the hardware module through the real-time message bus. The hardware module completes the change of the lamp position;

[0082] The intelligent operation and maintenance module sends a request for the change information of all vehicles to the alarm simulator through the real-time message bus. The alarm simulator returns the updated information to the intelligent operation and maintenance module, and the intelligent operation and maintenance module parses and processes it to display the alarm information on the terminal.

[0083] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
