The subsequent overall upgrade and modification will lead to an increase in development costs and a longer system update time; (4) When the total number of monitored devices is large, its display and control component cannot quickly view the status information of the target device; (5) When it needs to add new monitoring device objects, its display and control component lacks on-demand expansion capabilities; (6) Its display and control component lacks on-demand monitoring capabilities for monitoring the status information of airborne devices.

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Figure 1 A schematic diagram of a centralized monitoring system for airborne equipment situation provided by an embodiment of the present invention. Figure 1 As shown, the system consists of: an airborne computer display terminal (centralized monitoring software interface), an airborne equipment situation information centralized management device, and an airborne equipment heterogeneous bus interface integration and message forwarding control device (supporting routing forwarding control protocols for multiple types of interface bus messages.)

[0036] Airborne devices of various interface types can be connected to this centralized monitoring system through cables and bus slots to realize centralized visual management of the health status information of airborne devices. The airborne device bus concentration and message forwarding control device in the monitoring system is directly connected to each airborne device through the corresponding bus interface, and is connected to the airborne device situation information centralized management device through an Ethernet switch to form a local LAN. The computer display terminal is also connected through the local LAN and communicates with the airborne device situation information centralized management device. The monitoring software interface is the client or Web program running in the computer display terminal. The computer system equipment or devices in this monitoring system are all embedded hardware modules and their software components, and can be easily installed in designated locations on the aircraft without taking up too much space.

[0037] 1. Forwarding Control Device

[0038] Figure 2 A schematic diagram of an onboard device heterogeneous bus interface integration and message forwarding control device provided by an embodiment of the present invention, also known as an onboard device heterogeneous bus interface integrator (hereinafter referred to as: bus integrator). Figure 2 As shown, the device is a special computer device with multiple message bus interfaces and message forwarding control functions, which is used to centrally connect airborne devices of various interface bus types to this monitoring system, provide standardized processing of heterogeneous bus message formats of each airborne device, and forward them to the airborne device situation information centralized management device, and also used to distribute command messages issued by the airborne device situation information centralized management device to each airborne device.

[0039] The device usually includes a CAN bus interface, an Ethernet bus interface, an RS-232 serial communication bus interface, an RS-422 serial communication bus interface, an SRIO bus interface, an SPI bus interface, an LVDS bus interface, and an FC optical fiber communication bus interface, but is not limited to the above bus interfaces, wherein the Ethernet bus interface is an output interface, and the other bus interfaces are all input interfaces. The various input buses on the device can be used to connect different types of airborne devices, and the Ethernet output interface is used to connect to the upstream information centralized management device. The device plays a role in data information flow conversion. The heterogeneous data information flow enters through the input bus, and then is uniformly processed by the FPGA message forwarding control module in the device, and then output to the Ethernet bus interface in the same format information. Through this processing method, the device outputs all the heterogeneous data information of the airborne devices connected to the input interface in a unified and standardized format to the airborne device situation information centralized management device connected to the output interface. This shields the bus message differences of the underlying airborne devices, and provides a standardized Ethernet message processing method for the upper part, which is convenient for the future expansion of more types of heterogeneous airborne device bus interfaces, and any newly added interface bus will not affect the processing method of the upstream module of the device. Therefore, the upstream airborne equipment situation information centralized management device only needs to focus on processing standardized Ethernet messages to achieve intercommunication with various downstream airborne equipment. Even if the device physically adds an airborne equipment interface, there is no need to change the original processing method of the information centralized management device. This architectural design allows the device and the centralized management device to be updated, upgraded, and replaced separately without affecting each other, improving the overall modularity of the system.

[0040] The device implements a variety of bus message routing forwarding protocols inside. The protocol message header usually contains the following information elements: source device number, destination device number, message code, message type, message sequence number, message timestamp, message length, message check code, etc. The FPGA message forwarding control module determines which bus interface the message is sent to based on the source device number, destination device number, and the configuration information of the corresponding relationship between the device number and the bus. If the message is from the upstream airborne device situation information centralized management device to the downstream airborne device, the forwarding control module first reads the destination device number contained in the message header after receiving the unified message in Ethernet format, then finds the corresponding interface position through the interface bus relationship configuration information, and finally converts the Ethernet message into the corresponding interface bus message and sends it to the airborne device on the interface. Conversely, if the message is from the downstream airborne device to the upstream information centralized management device, the forwarding control module directly converts the interface bus message into a unified message in Ethernet format and sends it to the airborne device situation information centralized management device connected to the Ethernet.

[0041] 2. Airborne equipment situation information centralized management device

[0042] Figure 3 A schematic diagram of a centralized management device for airborne equipment situation information (hereinafter referred to as: centralized information management device) provided by an embodiment of the present invention. Figure 3 As shown, the device includes an embedded computer device with an Ethernet interface and a centralized situation information management program running therein. The centralized situation information management program running in the device includes a message centralized transceiver module for centralized processing of situation information of airborne equipment, a protocol centralized encoding and decoding module, an information centralized reporting module, and a centralized persistent storage module.

[0043] Through the Ethernet interface, first, the message centralized transceiver module of the information centralized management device receives the device status Ethernet message with a standardized format from the downstream bus integrator, then the protocol centralized encoding and decoding module encodes and decodes the Ethernet message, and then the centralized persistent storage module stores the necessary messages. Finally, the information centralized reporting module pushes the status information to the centralized monitoring software interface in the upstream computer display terminal in the local area network. The end user can view the health status information of the onboard equipment in a unified and real-time manner through the monitoring software interface.

[0044] The message centralized transceiver module is used to send and receive Ethernet type messages such as UDP data packets and ActiveMQ messages. Before the module starts running, first configure the Ethernet message transceiver mode adopted by the module, such as UDP data packet transceiver, ActiveMQ message transceiver and other transceiver modes. For UDP data packet transceiver, configure the Ethernet IP address and port number of this device as the receiving socket, and configure the Ethernet IP address and port number of the bus integrator as the sending socket; for ActiveMQ message transceiver, configure the message middleware Broker URL address, receiving topic string and sending topic string; the protocol centralized encoding and decoding module is used to parse the binary byte array data and JSON string data sent by the message centralized transceiver module into object data that can be read on the monitoring interface, and conversely, encode the object data generated and sent on the monitoring interface into binary byte array data and JSON string data that can be recognized by the message centralized transceiver module. In addition, the module also provides functions such as Base64 encoding and decoding and CRC16 verification of binary byte array data; the information reporting module is used to further encapsulate the object data information that can be read on the monitoring interface and push it to the computer display based on the WebSocket protocol. The message is presented on the centralized monitoring software interface in the terminal. The format of the pushed encapsulated message includes two parts: the message name and the message object data body. The message name is used by the interface module to identify different messages, and the message object data body is used to contain the specific meaning of the airborne equipment situation information. For example, a typical push message format is: {"name":"ccm-self-check-result","content":{"workStatus":"ok"}, the message name is "ccm-self-check-result", indicating that this is the self-check result of a certain module, and the message content is {"workStatus":"ok"}, indicating that the working status of the module is normal; the persistent storage module is used to store the necessary situation information in one of a variety of storage methods, including but not limited to lightweight file storage of embedded computer devices, relational database storage, object storage, etc. The situation information containing only the specified message identifier is stored in a parameter configuration manner to avoid indiscriminate storage of all situation information, resulting in rapid exhaustion of storage space resources. By configuring parameters, only the status information that has changed and is reported over a specified time interval is stored to prevent the storage of too much identical status information when a network storm occurs, which would fill up the storage space in a short period of time. This highly flexible on-demand storage method for status information improves the robustness of the system and provides a data basis for equipment health analysis.

[0045] 3. Airborne computer display terminal (centralized monitoring software interface)

[0046] Figure 4 This is a schematic diagram of the centralized monitoring software interface of the onboard computer display terminal provided by the embodiment of the present invention. Figure 4 As shown, the onboard computer display terminal is loaded with a centralized monitoring software interface, which presents the onboard equipment status information to the onboard equipment operation and maintenance personnel.

[0047] The centralized monitoring software interface provides a device partition presentation method, which includes a device block panel control, an outer device container control accommodating multiple device block panel controls, and a device filter control for filtering the device block panel.

[0048] The device block panel control presents the status information of a single device on a device block panel. The device block panel is divided into three parts from top to bottom: the device title bar, the device control bar, and the device status area. This presents the status information of a single device on the same device block panel, which makes it easy for users to quickly view all information of a single device among many devices, and also facilitates the expansion of new devices on demand in the same way.

[0049] The outer device container control automatically places multiple device block panel controls in a row and column layout on the interface. According to different screen resolutions, the outer device container control automatically adjusts the number of device block panel controls that can be placed in each row. This method provides an automatic adjustment capability for computer display terminals of different sizes. If the number of device block panel controls exceeds the range that can be displayed on one screen, the outer device container control provides a vertical infinite scroll bar to scroll downward, thereby realizing the monitoring of device status information of any number of airborne devices.

[0050] The device filter control is a control for filtering and displaying the device block panel in the interface. This control provides an import button and a selection list. First, the predefined device domain configuration information can be imported using the import box, and then the specified device domain can be selected through the selection list. When a device domain is selected, the outer device container control only displays the device block panel composed of the devices specified in the device domain, and all device block panels not in the domain are hidden. By default, the selection list selects the entire domain, that is, all device block panels are displayed. The device domain is data information containing the device name of a specific device block panel control, which is usually a subset of the device names managed by the monitoring software. This method can quickly filter and display the devices of interest according to the specified device domain when the number of monitored devices is large, so as to quickly locate the device panel where the device status information to be viewed is located. The device block panel control can realize on-demand display of the specified status reporting information of the onboard device by reading the status monitoring information configuration of the onboard device corresponding to the device panel. For the onboard device status that is not desired to be displayed, the device block panel hides it, so as to achieve on-demand monitoring of more fine-grained status information elements according to user needs. The status monitoring information configuration is a setting parameter file for the correspondence between the device status identifier and the monitoring switch, where the device status identifier is the "name" value of the push message format data, and the monitoring switch is a Boolean value of true or false. A typical status monitoring information configuration is as follows: NavDev: {workStatus: true, fanStaus: true, manufacturerFacturer: false, indicatorLight: false}, which means that the navigation device NavDev has 4 status information, namely working status, fan status, manufacturer name, and indicator light status. Among them, the working status and fan status are set to true, and these two states will be displayed on the display interface; the manufacturer name and indicator light status are set to false, and these two information will be hidden on the display interface.

[0051] Figure 5 A flow chart of a method for centralized monitoring of airborne equipment status provided by an embodiment of the present invention. Figure 5 As shown, the method includes four steps: airborne device access, heterogeneous message forwarding, device message processing, and situation information presentation.

[0052] 1) Airborne equipment access

[0053] According to the interface bus type supported by the airborne equipment, each airborne equipment is connected to the corresponding message bus interface of this monitoring system. The physical connection method can be selected as slot connection or cable connection. After completing the centralized access of the system, each airborne equipment can communicate with this monitoring system.

[0054] 2) Heterogeneous message forwarding

[0055] The airborne devices connected to different interface buses of this monitoring system send heterogeneous messages of the airborne devices to this monitoring system. After the original message is standardized and processed in a format by the forwarding control device, it is forwarded to the information centralized management device connected to the Ethernet interface of the monitoring system for reception. Conversely, this monitoring system sends query, self-test and other command messages to the airborne devices. The command messages are first sent by the information centralized management device to the forwarding control device, and then the latter encapsulates the received messages into bus interface messages that can be recognized by the corresponding airborne devices, and finally received by the airborne devices.

[0056] 3) Device message processing

[0057] After receiving the standardized device message, the information centralized management device parses the message field information one by one, constructs the data transmission object that can be recognized by the display terminal monitoring software interface, and pushes the data transmission object to the monitoring software interface where the display terminal is located. Conversely, the information centralized management device encapsulates the query, self-check and other operation commands issued by the monitoring software interface where the display terminal is located into a standardized device message and sends it to the forwarding control device. During the message processing process, if the relevant information needs to be stored, the information centralized management device completes the persistent storage.

[0058] 4) Situation information presentation

[0059] After all the information of airborne equipment is pushed and reported to the monitoring software where the display terminal is located, the monitoring software program will reorganize the information by category, partition, and device and present it on the graphical user interface, forming intuitive and visual airborne equipment situation information, which is convenient for airborne equipment operation and maintenance personnel to comprehensively monitor the health status of equipment and diagnose equipment failures. For example, it also continuously records the specific status information of the designated monitoring equipment, and performs abnormal mode detection and alarm.
