[0002] With the rapid development of unmanned technology, more and more unmanned equipment is applied to firefighting, medical and other fields, and unmanned helicopters are becoming more and more comprehensive in terms of models and functions. Power-on inspection is a common means to determine the operating status of unmanned helicopter electronic equipment. It is widely used in the production and use stages of unmanned helicopters. For example, in the final assembly, pre-flight inspection, re-flight inspection, post-flight inspection, replacement of faulty parts and other scenarios, the power-on inspection method is used to determine whether the unmanned helicopter can work normally.

[0003] However, during the use and maintenance of unmanned helicopters, there is no person on board to operate them, and they can only be remotely controlled through ground stations, which significantly reduces the efficiency of use and maintenance. During the power-on inspection of unmanned helicopters, one operator is often required to operate at the ground station and another operator is required to observe near the unmanned helicopter, which is not only inefficient but also may lead to the risk of errors. Summary of the invention

[0004] Purpose of the invention: To provide a fast power-on inspection method for unmanned helicopters, avoid remote operation of the unmanned helicopter and the ground station during the power-on inspection process, and simplify the operation process of the power-on inspection, which can significantly improve the power-on inspection operation of the unmanned helicopter, thereby improving the use and maintenance efficiency of the unmanned helicopter.

By optimizing the system cross-linking structure, reasonable system layering, and different task planning, the power-on inspection efficiency of unmanned helicopters is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a principle block diagram of a method for rapid power-on inspection of an unmanned helicopter provided in an embodiment of the present application. DETAILED DESCRIPTION

[0029] The present invention introduces a method for rapid power-on inspection of an unmanned helicopter. As a common maintenance method for determining the working status of electronic equipment of an unmanned helicopter, power-on inspection often requires the cooperation of a ground station. In order to avoid the disadvantage that the unmanned helicopter can only be remotely operated through a ground station during the power-on inspection process, the present invention provides a rapid power-on inspection operation method that does not require remote operation by a ground station.

[0030] Attached Figure 1 The invention describes the connection mode between the portable external operating platform and the unmanned helicopter, the cross-linking relationship of the power-on inspection part inside the unmanned helicopter, and the power-on inspection function that can be realized by the portable external operating platform.

[0031] First, the method of the present invention connects the HUMS system of the unmanned helicopter through a portable external operating platform, and the connection method is AFDX wired connection. The advantages of this method are simple, fast, reliable, and convenient for replacing the connecting cable after a failure. By implementing the power-on inspection operation of the unmanned helicopter electronic equipment on the portable external operating platform, the operator only needs to stand around the unmanned helicopter and hold the external operating platform to implement the power-on inspection without the need for remote operation of the ground station. In order to realize the power-on inspection of the unmanned helicopter electronic equipment by the external operating platform, the HUMS system of the unmanned helicopter is also required to perform data cross-linking with other electronic systems or equipment. In order to avoid the excessive complexity of the cross-linking between HUMS and each device or system, in the design process, full reference is made to the original cross-linking form of the unmanned helicopter's electronic equipment. Considering that most electronic systems or equipment are cross-linked with the flight control computer or the integrated task processing system, the present invention only cross-links the HUMS system with the flight control computer and the integrated task processing system through the bus, thereby simplifying the complexity of the cross-linking between the systems. After the cross-linking relationship required for the power-on inspection is realized, in the design of the portable external operating platform, since the unmanned helicopter contains many power systems or equipment, in order to avoid disordered and chaotic power-on inspections,

[0032] The present invention adopts a system-based hierarchical approach, treating each system of the unmanned helicopter (such as the avionics system, electrical system, etc.) as an independent power-on inspection item.

[0033] Then, within each system, the electrical equipment within the system is treated as an independent power-on inspection item and numbered sequentially.

[0034] During the power-on check, you can quickly check the power-on of the target device by selecting layer by layer on the portable external operating platform, or you can directly select a single system for power-on check, and complete the power-on check of each device in sequence according to the pre-set sequence numbering, and then complete the power-on check of the entire system. If necessary, you can also directly select the power-on check of the entire unmanned helicopter, and complete the power-on check of each system according to the pre-set sequence numbering, and then complete the power-on check of the unmanned helicopter.

[0035] In addition to adopting a system-based hierarchical approach to improve the efficiency of power-on inspection, this method also adopts a method based on task requirements to carry out power-on inspection methods in different scenarios, because the power-on inspection items after replacing the faulty parts are often different from the power-on inspection items before flight. The power-on inspection after replacing the faulty parts is often more comprehensive and sometimes requires certain operations. The power-on inspection items before flight are often only carried out on the important functions of important equipment, without the need for operation, and the inspection items for the power-on inspection of the next flight will be fewer. Therefore, by adopting this method based on task requirements, different inspection items are set for different tasks, which is conducive to improving the efficiency of power-on inspection. Considering that as the flight time of unmanned helicopters increases, some equipment no longer needs power-on inspection, while some equipment has an increased possibility of failure due to the increase in working time, and more frequent power-on inspections are required, these can be adjusted within the task requirements. The power-on inspection items can even be customized.

[0036] It should be noted that:

[0037] 1. By connecting to a portable operating platform, the drone can be powered on and checked without the need for a ground station.

[0038] 2. Use the HUMS system as a carrier to complete the power-on inspection, optimize the cross-linking relationship of the electronic systems of the unmanned helicopter, and avoid complex and redundant system cross-linking;

[0039] 3. Based on the system-based hierarchical approach, disorderly and chaotic power-on inspections can be avoided, and power-on inspections of individual devices, systems and complete machines can be realized;

[0040] 4. Based on the task requirements, optimize the power-on inspection items in different scenarios to avoid duplication and unnecessary inspection items.

[0041] In other embodiments of the present application, the power-on check operation steps are described (taking the power-on check of the laser inertial navigation device of the avionics system as an example):

[0042] Step 1: Activate the power-on check command signal of the laser inertial navigation device under the avionics system menu in the portable external operating platform. At this time, "Laser inertial navigation device is being powered on for check" is displayed on the portable external operating platform;

[0043] Step 2: The command signal is transmitted to the HUMS system via the AFDX bus;

[0044] Step 3: The HUMS system receives and processes the command signal, and transmits the command signal to the integrated task processing system through the bus on the unmanned helicopter for unified planning;

[0045] Step 4: After receiving the power-on inspection command signal, the integrated task processing system transmits the command signal to the laser inertial navigation device at an appropriate time according to the current task arrangement of the unmanned helicopter;

[0046] Step 5: After receiving the power-on inspection command, the laser inertial navigation device enters the maintenance mode and starts maintenance self-detection;

[0047] Step 6: After the maintenance self-test of the laser inertial navigation device is completed, the maintenance self-test result data is packaged and sent to the flight control management system;

[0048] Step 7: The flight control management system does not process the data and directly transmits it to the HUMS system;

[0049] Step 8: The HUMS system transmits the maintenance self-detection data to the portable external operating platform through the AFDX bus;

[0050] Step 9: The portable external operating platform decodes the maintenance self-test data according to the set protocol and displays it on the interface. The "Detailed Inspection" command will appear at the bottom of the interface;

[0051] Step 10: First, the first line of the interface displays the system name, such as "Laser Inertial Navigation Device", and the second line displays the software version of the current device, such as "V2.3.0". The maintenance personnel must first determine whether the system name and software version are correct to ensure the accuracy of the inspection object. The third line displays whether there is a fault in the system, such as "No Fault". When a fault is displayed, the fault-related information will be displayed below, including the fault code, fault occurrence time and other information. The maintenance personnel can perform further troubleshooting based on this fault information;

[0052] Step 11: At this point, you can only preliminarily determine whether the laser inertial navigation device can work properly. This step is often used to quickly power on the device before and during flight. If a detailed power-on check is required, you can activate the "Detailed Check" command to enter the detailed check interface of the laser inertial navigation device;

[0053] Step 12: After activating the command, the command signal is sent to the HUMS system through the AFDX bus. At this time, the HUMS system will receive the working data sent by the laser inertial navigation device to the flight control management system in real time, and send the working data to the portable external operating platform through the AFDX bus. After decoding, the relevant working parameters of the laser inertial navigation device will appear on the interface, such as "alignment longitude", "alignment latitude", "alignment altitude" and other important information. At this time, the maintenance personnel can further judge the working status of the laser inertial navigation device based on this information;

[0054] Step 13: In addition to reading the working data, on the detailed inspection interface, there will also be operation command buttons such as "navigation alignment" (Note: the operation button functions of different devices are different). You can send the command signal by clicking the "navigation alignment" operation command;

[0055] Step 14: After the command signal is sent to the HUMS system through the AFDX bus, the HUMS system sends the command signal to the integrated task processing system, and the integrated task processing system sends the signal to the laser inertial navigation device at an appropriate time, and the laser inertial navigation device starts to execute the "alignment" command; after the alignment is completed, the new working status parameters will be transmitted back to the portable external operating platform for maintenance personnel to read and analyze;

[0056] Step 15: At this point, the power-on check of the laser inertial navigation device has been completed. If each step is normal, it can be determined that the device is working properly. At this time, you can close the software or choose to send other power-on check instructions to start power-on checks on other systems.
