Description

Technical Field

[0001] This invention relates to the field of navigation, and more particularly to an integrated navigation display and control console testing platform. Background Technology

[0002] Existing integrated navigation display and control console testing equipment has many shortcomings, mainly due to the limitations of traditional testing methods and techniques. Firstly, traditional testing methods typically rely on multiple different testing devices and tooling. This approach is not only inefficient but also complex to operate, with cumbersome testing procedures that often require manual intervention, resulting in a high-cost and high-risk operating environment. More seriously, existing equipment and tooling are usually spatially dispersed, which not only prevents centralized testing but also increases management difficulty and reduces work efficiency.

[0003] Furthermore, current testing methods have significant shortcomings in terms of comprehensiveness and accuracy. As a highly integrated system, the comprehensive verification of the accuracy indicators of the integrated navigation display and control console is crucial, but existing methods cannot meet this requirement. For example, they cannot effectively detect information communication faults and communication accuracy failures of the integrated navigation display and control console. These accuracy indicators directly affect the console's performance and accuracy assurance in actual use. Because these critical accuracy issues cannot be effectively verified, the accuracy of the integrated navigation display and control console in actual operation is difficult to ensure, thus affecting its reliability and performance in complex tasks.

[0004] The PC104 architecture of integrated navigation display and control consoles offers diverse external connection types and interface quantities, providing high flexibility in communication and data exchange. However, existing testing methods do not fully utilize these characteristics for systematic testing. Currently, the common testing method involves communicating with the display and control console via a laptop equipped with a serial port debugging assistant and a USB-to-422 debugging cable. While this method can provide some simple confirmation of the hardware link, it essentially relies on a single interface for data transmission and reception. This testing method cannot comprehensively verify the correctness of data transmission and reception, especially in complex systems and module collaborations, making it difficult to ensure the accuracy and reliability of data interaction between modules.

[0005] Patent CN102506901A discloses a multi-channel navigation information simulation and integration system. This system includes a PC104 architecture computer, a monitoring display, input devices, an RS232 / RS485 asynchronous serial interface chip, and an interface device. The system simulates navigation equipment information and displays it on the monitoring display, providing a human-machine interface. The interface device connects to the target device. However, it requires testing the information modules of the integrated navigation display and control console, verifying the hardware link's functionality through message transmission and reception. This does not guarantee the accuracy of the transmitted and received data. Existing methods have significant vulnerabilities, particularly in testing critical modules such as the 1553B interface, chart module, and tracker module, lacking effective testing methods. For the display and human-machine interface, the testing process is even more fragmented, lacking overall coherence and systematicity, and failing to ensure the stability and consistency of display effects and interactive functions across various operating modes. Summary of the Invention

For example, it can test whether the driving direction of the two actuators on the X-axis and Y-axis is perpendicular, whether the distance of each round trip is consistent, and the consistency of movement along one direction. This effectively tests the drawing accuracy of the integrated navigation display and control console in actual work.

[0036] 8. Through integrated testing on this platform, the performance and accuracy of each module of the integrated navigation display and control console can be effectively improved, ensuring the efficient operation of the system in practical applications. This is of great significance for ensuring the reliability and accuracy of the navigation system, especially in demanding navigation and navigation tasks, where it can reduce the occurrence of errors and malfunctions.

[0065] The motherboard provides two network ports and one RS-232 serial port; the multi-serial port card includes a 24-channel RS-422 serial port card, two-channel CAN cards, two-channel 1553B interface cards, and one-channel signal generation adapter board; the fixed interface simulation device also includes a customized serial port simulator, network port simulator, CAN interface simulator, 1553B interface simulator, and IO simulation interface simulator, used to simulate various interfaces. The interface simulation device is connected to the device under test, and the corresponding simulator is selected for data transmission and reception.

[0066] In this embodiment, the fixed interface simulation device is based on an industrial control computer, and includes a 4U industrial control chassis, a motherboard, a CPU, a hard drive, a multi-serial port card (24 channels), a CAN card, and a 1553B card. The CPU is mounted on the motherboard. The hard drive, the 24-channel multi-serial port card, the CAN card, and the 1553B card are connected to the motherboard via signals. The motherboard is housed within the 4U industrial control chassis. The fixed interface simulation device provides an external interface for the navigation sensor. It also includes a CF card reader connected to the motherboard via signals. The device further includes a signal generation adapter board connected to the motherboard via signals. The adapter board has one external interface for stern shaft simulation. Finally, the device includes a display device and a human-machine interface input device. The display device is a monitor for receiving video signals output from the motherboard. The human-machine interface input device is a keyboard and a touchpad for inputting human-machine interaction commands to the motherboard.

[0067] In this embodiment, a CAN interface simulator is used to simulate a navigation sensor that transmits and receives CAN interface type data connected to the PC104 structure integrated navigation display and control console under test, and the two perform data transmission and reception between each other; an IO interface simulator is used to simulate a navigation sensor that transmits and receives IO interface type data connected to the PC104 structure integrated navigation display and control console under test, and the two perform data transmission and reception between each other; the 1553B interface simulator is used to simulate a navigation sensor that transmits and receives 1553B interface type data connected to the PC104 structure integrated navigation display and control console under test, and the two perform data transmission and reception between each other.

[0068] Implementation Method Four: This implementation method further defines the integrated navigation display and control console testing platform described in Implementation Method One. The fixed interface simulation device integrates serial port debugging tools and network debugging tools, runs under the Windows system, adapts to relevant interface drivers, selects the serial port / network port debugging tool, outputs the data to be sent in the debugging tool, and checks the receiving status of the device under test; at the same time, the device under test sends data to the fixed interface simulation device, and checks the data receiving status of the fixed interface simulation device.

[0069] In this embodiment, the serial port debugging tool is used to monitor the data transmission and reception status between the serial port simulator and the PC104 structure integrated navigation display and control console under test, to determine whether the two can communicate normally and whether the transmitted and received data is correct; the network port debugging tool is used to monitor the data transmission and reception status between the network port simulator and the PC104 structure integrated navigation display and control console under test, to determine whether the two can communicate normally and whether the transmitted and received data is correct.

[0070] Implementation Method 5: This implementation method further defines the integrated navigation display and control console testing platform described in Implementation Method 1. The fixed interface simulation device also has a simulated sensor port selection function, which is used to simulate any sensor port. After the physical connection between the device under test and the simulator is completed, a certain interface is opened in the simulator, and the device under test and the simulator conduct data transmission and reception communication.

[0071] The fixed interface simulation device described in this embodiment also includes a UI interface; the UI interface has a debugging toolset and a simulator window; in the debugging toolset, debugging tools can be selected; in the simulator window, the simulator interface can be entered, the interface displays the status of all simulators, and clicking on the corresponding simulator will enter the simulator pop-up window to view specific data, and multiple simulation screens can be displayed simultaneously.

The fixed interface simulation device also has an interface status indication function, using color coding to display the status of each sensor interface. Green represents data transmission, orange represents a selected port, and no color represents no communication. Through color coding (such as green, orange, and no color), operators can easily identify the status of each sensor interface. When an interface displays no color or orange during testing, it indicates a potential connection problem or misconfiguration. Operators can promptly troubleshoot and repair this issue, avoiding delays in work progress.

[0073] Implementation Method Seven: This implementation method further defines the integrated navigation display and control console testing platform described in Implementation Method One. The chart display and information display are located on the top of the console. The top of the console is also equipped with a keyboard, including a chart keyboard, an information keyboard, and a tracker keyboard, for operating the chart module, information module, and tracker module. A four-in-one reinforced keyboard is used.

[0074] In this implementation, dedicated chart keypads, information keypads, and tracker keypads allow operators to quickly and accurately control different functional modules independently.

This design helps simplify complex navigation tasks and reduces the operator's workload.

[0076] Implementation Method Nine: This implementation method is a further limitation of the integrated navigation display and control console testing platform described in Implementation Method One. The operating console is also provided with a cable hanging area, which is a perforated board used to suspend equipment.

[0077] In this embodiment, suspending the equipment on a pegboard makes it more convenient and efficient for operators to use, reducing the space occupied by the equipment on the workbench. Suspending the equipment also makes it easier to access, inspect, or repair various instruments or tools, effectively improving work efficiency.

Whether adjusting the platform's position or performing testing operations in different areas, the casters allow for convenient and quick movement of the equipment, reducing the difficulty and time required for manual handling.

[0080] Implementation Method Eleven: This implementation method provides a specific embodiment of the integrated navigation display and control console testing platform described in Implementation Method One, and also serves to explain Implementation Methods Two to Ten. Specifically:

[0081] In this embodiment, the integrated navigation display and control console testing platform consists of module debugging and testing fixtures, a fixed interface simulation device, and an operating console.

[0082] The module debugging and testing fixture consists of a (metal / plastic) shell, a Xinhaihang base plate, an external interface board, a switch, and a voltage test contact / voltage digital display module.

[0083] Using a (metal / plastic) casing as a carrier, it houses the Xinhaihang baseplate and a voltage digital display module (design optional). External interface boards are mounted on both sides, each equipped with 20 422 serial ports, 2 CAN interfaces, 2 1553B interfaces, 2 Ethernet ports, 1 I / O interface, an information module display interface, a chart module display interface, and a human-machine interface (HMI) output interface. Internal connections utilize high-temperature cables. The HMI output interface allows for interactive operation of the information and chart modules. The power supply and voltage digital display modules are located on the control panel area. The overall diagram of the integrated navigation display and control console module debugging and testing fixture is shown below. Figure 9 As shown.

[0084] In this embodiment, the digital display module is used to display the voltage of the power supply module;

[0085] By loading the module under test into the module debugging and testing fixture and connecting it to the simulator, the interface information communication can be tested in conjunction with the simulator.

[0086] By loading the information module board under test into the module debugging and testing fixture and connecting it to the simulator, the interface to be tested can be selected in the simulator to check whether the information module board is normal.

[0087] By installing the chart module / motherboard under test into the module debugging and testing fixture and communicating with the information module, it is possible to check whether the chart module / motherboard is functioning properly.

[0089] By connecting the human-computer interaction part to the module debugging and testing fixture, we can check whether the human-computer interaction part is normal.

[0090] The fixed interface simulation device 12 is used to detect whether the external interface communication of equipment such as the integrated guide station is normal. By detecting the faulty interface, it can quickly determine which hardware in the external interface module (mainly information module and interface module) of the integrated guide station or other equipment is faulty. For example, if the GPS interface communication is interrupted, connect the interface simulation device to the GPS interface of the integrated guide station or other equipment, and use the simulator to send GPS data to the equipment. If the equipment cannot receive it, it can be considered that the serial port card in the information module is faulty. Replace the serial port card and check whether it returns to normal.

[0091] In this embodiment, the fixed interface simulation device is based on an industrial computer and consists of a 4U industrial computer chassis, a full-size keyboard, a mouse touchpad, a hard drive, a motherboard (2 Ethernet ports, 1 RS-232 serial port), a multi-serial port card (24 ports), a CAN card (2 ports), and a CF card reader. A 1553B interface (2 ports) and a signal generation adapter board (1 port, stern shaft simulation) can be optionally added as needed.

It can run on Windows 10 and is compatible with relevant interface drivers. Users can select the serial / network port debugging tool, output the data to be sent, and check the receiving status of the device under test. Simultaneously, the device under test sends data to the fixed interface simulation device, and the data receiving status of the fixed interface simulation device is checked. This method allows for the inspection of the working status of general-purpose devices.

[0093] The fixed interface simulation device also includes a customized serial port simulator to simulate serial port interface data of the device. By connecting the interface simulation device to the device under test and selecting the appropriate simulator for data transmission and reception, the data transmission and reception status between the device under test and the interface simulation device can be visually checked, and the relevant interface data are consistent.

[0094] The fixed interface simulation device also includes a customized network port simulator to meet the simulation of network port interfaces of the device. By connecting the interface simulation device to the device under test and selecting the corresponding simulator for data transmission and reception, the data transmission and reception status between the device under test and the interface simulation device can be visually checked, and the relevant interface data is consistent.

[0095] The fixed interface simulation device also includes a customized CAN interface simulator to meet the CAN interface simulation of the device. By connecting the interface simulation device to the device under test and selecting the appropriate simulator for data transmission and reception, the data transmission and reception status between the device under test and the interface simulation device can be visually checked, and the relevant interface data are consistent.

[0096] The fixed interface simulation device also includes: a customized 1553B interface simulator, which is used to simulate the 1553B interface of the device. By connecting the interface simulation device to the device under test and selecting the corresponding simulator for data transmission and reception, the data transmission and reception status between the device under test and the interface simulation device can be visually checked, and the relevant interface data are consistent.

[0097] The fixed interface simulation device also includes: a customized IO simulation interface simulator, which is used to simulate the stern shaft interface of the device. By connecting the interface simulation device to the device under test and selecting the appropriate simulator for data transmission and reception, the data transmission and reception status between the device under test and the interface simulation device can be visually checked, and the relevant interface data is consistent.

[0098] The fixed interface simulation device also has the function of simulating sensor port selection. The fixed interface simulation device can simulate any sensor port. The simulator can adapt to communication. The physical line between the device under test and the simulator is completed. When a certain interface is opened in the simulator (for example, the GPS interface is selected), the device under test and the simulator can carry out data transmission and reception communication.

[0099] The fixed interface simulation device also has an interface status indication function, which uses color coding to display the status of each sensor interface. Green represents data transmission, orange represents the selected port, and no color represents no communication.

[0100] The fixed interface simulation device also supports UI customization. The UI interface has a toolset and a simulator window. Clicking the toolset allows you to select tools. Within the toolset, you can close and exit to select other tools, or you can open the same tool multiple times. Clicking the simulator window allows you to enter the simulator interface, which displays the status of all simulators.
