This method improves the anti-interference ability of drone signals, ensures the reliable transmission of key sensitive data, and thus effectively improves the normal operation effect of the flight control system.

[0005] With the development of drone technology, drones have become indispensable disaster relief auxiliary equipment. Therefore, before disaster relief drones are put into use, network performance testing is required. Existing network performance testing systems for ad-hoc wireless communication devices can detect according to preset test environments and automatically generate test reports. However, during the detection process, especially when detecting the tolerance limit of drones, it is extremely easy to cause irreversible damage to the drones being tested, resulting in high detection costs. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that during the detection process of the network performance testing system for ad-hoc wireless communication devices, especially when detecting the tolerance limit of drones, it is extremely easy to cause irreversible damage to the drones being tested.

[0007] To solve the above problems, the present invention provides a network performance testing system for wireless ad-hoc communication devices, which includes an output display device. The output display device is respectively connected to a signal interference device, a drone control device, and a drone body through signals. The drone control device and the drone body are connected through signals. The output display device is respectively connected to the signal interference device and the drone control device through wires.

[0008] Its usage method includes:

[0009] S1. Test method design: Design corresponding conventional detections according to the target environments in which the drone control device and the drone body work. For example, in environments with complex geomagnetic conditions and weak signal environments, and then add additional detection items based on the actual situation on the basis of the conventional detections: pressure test, interference test, and stability test.

[0010] S2. Environment construction: Build a network performance test environment according to the test method in step S1. During the environment construction process, it is necessary to ensure the repeatability and expandability of the construction process. The repeatability means that during multiple tests, the conditions of the network performance test environment are the same each time, and the expandability means that interfaces are reserved during the installation process to facilitate the temporary addition of additional detection items after the preset detection items are completed.

[0011] S3. Test execution: Detect the designed conventional detections and additional detection items according to step S1. The detection indicators include: throughput, latency, packet loss rate, and information coverage.

[0012] In the above-mentioned network performance testing system for wireless ad-hoc communication devices, once the drone control device and the drone body show similar working data, the signal interference device is shut down in time to avoid damage to the drone control device and the drone body due to the interference test, and reduce the detection cost.

[0013] As a further improvement of the present application, a plurality of drone control devices are installed on the signal interference device. Each of the plurality of drone control devices includes a signal transfer device and an antenna body, and the signal transfer device is threadedly connected to the antenna body. The drone control device is signal-connected to the signal interference device through the signal transfer device. An additional outer shell is sleeved on one side of the signal transfer device close to the antenna body. A sealing cover matching itself is threadedly connected to the opening at one end of the additional outer shell close to the antenna body. A fixing base matching itself is fixedly connected inside the additional outer shell. An indentation groove is dug at the upper end of the fixing base close to the signal transfer device. An emergency unit is fixedly connected to the lower end of the sealing cover, and the sealing cover and the emergency unit are fixedly connected by hot melt adhesive. The emergency unit includes a glass ring. An electric heating mesh is fixedly connected to the inner wall of the glass ring. The glass ring is filled with hot melt adhesive. A plurality of corrosion balls are filled in the hot melt adhesive, and the corrosion balls and the hot melt adhesive do not react with each other. The density of the hot melt adhesive is less than that of the corrosion balls. The structural design of the additional outer shell and its interior transfers the damage that may be caused to the drone control device and the drone body during the electromagnetic interference test of the wireless ad-hoc network communication device to the signal transfer device with lower cost, reducing the cost during the electromagnetic interference test of the wireless ad-hoc network communication device.

[0014] As a further improvement of the present application, the filling amount of the hot melt adhesive is two-thirds of the volume inside the glass ring, making the glass ring easier to break when it falls.

[0015] As a further improvement of the present application, the additional outer shell includes a shell body. A plurality of installation grooves are dug at the upper end of the shell body. A heat dissipation unit matching itself is inserted into each of the plurality of installation grooves, increasing the heat exchange efficiency between the inner and outer sides of the additional outer shell and not easily accumulating too much heat inside the signal transfer device to cause irreversible damage to the signal interference device.

[0016] As a supplement to the further improvement of the present application, a heat dissipation groove is dug at one end of the heat dissipation unit located outside the additional outer shell. On the one hand, it increases the specific surface area of the heat dissipation unit, and on the other hand, it increases the friction force, facilitating the plugging and installation of the heat dissipation unit.

[0017] As another improvement of the present application, a plurality of air vents are dug on the side wall of the additional outer shell. All of the plurality of air vents are located in the upper half of the shell body. The existence of the air vents can realize air exchange with the outside world, avoid excessive high-pressure gas accumulating inside the additional outer shell, not easily cause the shell body to break, and not easily cause accidents of corrosion ball leakage.

[0018] As a further improvement of the present application, a protective curtain is fixedly connected to the lower end of the sealing cover. The protective curtain is sleeved on the outside of the emergency unit. The protective curtain can buffer the fragments of the emergency unit and avoid the fragments of the emergency unit directly damaging the additional outer shell.

[0019] As a supplement to the further improvement of the present application, the protective curtain includes a fine mesh curtain, which is a mesh structure woven from elastic fibers, increasing the buffering effect and impact resistance of the protective curtain.

[0020] As a supplement to the further improvement of the present application, a plurality of counterweights are fixedly connected to one end of the fine mesh curtain away from the sealing cover, and the counterweights shift in position when the fine mesh curtain is impacted by the debris of the emergency unit. Without affecting the buffering effect of the fine mesh curtain, the counterweights can quickly restore the fine mesh curtain and quickly resume the buffering effect.

[0021] In summary, in the present application, the structural design of the additional housing and the interior transfers the damage that may be caused to the drone control device and the drone body during the electromagnetic interference test of the wireless ad-hoc network communication device to the signal transfer device with lower cost, reducing the cost of the electromagnetic interference test process of the wireless ad-hoc network communication device.

[0022] At the same time, during the electromagnetic interference test, when the electromagnetic interference received by the drone control device and the drone body reaches the limit, the output display device can be directly shut down through the signal interference device to stop the electromagnetic interference. When the signal interference device freezes due to long-term testing or high-power testing, the hot melt adhesive is activated to damage the signal transfer device and cut off the connection between the antenna body and the signal interference device. The antenna body can no longer generate interfering electromagnetic waves, stopping the electromagnetic interference to the drone control device and the drone body. The structural design of the additional housing and the interior transfers the damage that may be caused to the drone control device and the drone body during the electromagnetic interference test of the wireless ad-hoc network communication device to the signal transfer device with lower cost, reducing the cost of the electromagnetic interference test process of the wireless ad-hoc network communication device.

[0035] The following describes the two embodiments of the present application in detail with reference to the accompanying drawings.

[0036] The first embodiment:

[0037] Figure 1 A wireless ad-hoc network communication device network performance test system is shown, including an output display device 2, which is respectively signal-connected to a signal interference device 1, a UAV control device 3 and a UAV body 4. The UAV control device 3 and the UAV body 4 are signal-connected, and the output display device 2 is respectively wired-connected to the signal interference device 1 and the UAV control device 3;

[0038] Its usage method includes:

[0039] S1. Test method design: Design corresponding regular tests according to the target environment in which the UAV control device 3 and the UAV body 4 operate. For example, in an environment with complex geomagnetic conditions and weak signal environments, additional test items are added based on the actual situation on the basis of regular tests: pressure test, interference test, and stability test. Among them, the pressure test is for the working environment with high-bit-rate communication requirements of the UAV body 4, and the interference test is for the working environment with complex magnetic fields in the working environment of the UAV body 4. Corresponding electromagnetic interference is added in the target environment according to the test requirements. In addition to detecting the anti-electromagnetic interference capabilities of the UAV control device 3 and the UAV body 4, the electromagnetic interference intensity is increased or decreased according to the working data transmitted back in real time by the UAV control device 3 and the UAV body 4, and the maximum interference intensity that the UAV control device 3 and the UAV body 4 can withstand is detected. The stability test is for the environment where the UAV body 4 needs to work continuously for a long time;

[0040] S2. Environment construction: Build a network performance test environment according to the regular test target environment designed in step S1, the test method. During the environment construction process, it is necessary to ensure the repeatability and expandability of the construction process. Among them, repeatability means that in multiple test processes, the conditions of the network performance test environment are the same each time, and expandability means that interfaces are reserved during the installation process to facilitate the temporary addition of additional test items after the preset test items are completed;

[0041] S3. Test execution: Conduct tests on the regular tests and additional test items designed in step S1. The test indicators include: throughput, latency, packet loss rate, and information coverage.

[0042] In this application, the network performance of the UAV control device 3 and the UAV body 4 in a harsh environment is tested. The UAV control device 3 controls the UAV body 4 to perform disaster relief terrain survey, personnel search, and secondary disaster warning work. The UAV control device 3 can control the work of the UAV body 4 and at the same time convert the data information transmitted back by the UAV body 4 into videos, images, and text to assist in disaster relief. The UAV control device 3 and the UAV body 4 will transmit the relevant data of their own network performance to the output display device 2. The output display device 2 summarizes the network performance test data and results of the UAV control device 3 and the UAV body 4, and generates a test report after the test. The presence of the signal interference device 1 can generate a corresponding interference electromagnetic environment during the test according to the test needs, and change the interference electromagnetic environment according to the process changes, affecting the work of the UAV control device 3 and the UAV body 4 to judge the network performance of the UAV control device 3 and the UAV body 4 in a harsh and loaded environment.

[0043] Specifically, in step S1, the test method design, when designing the limits for the drone control device 3 and the drone body 4, destructive testing is first carried out. After adding sufficient physical protection to the drone body 4, the signal interference device 1 applies increasing electromagnetic interference to the drone control device 3 and the drone body 4 until the drone control device 3 and the drone body 4 cannot establish a normal signal connection and the drone body 4 falls from a high altitude. Record the current limit working data of the drone control device 3 and the drone body 4. During the test in step S3, once the drone control device 3 and the drone body 4 show similar working data, immediately turn off the signal interference device 1 to prevent the drone control device 3 and the drone body 4 from being damaged due to the interference test and reduce the detection cost.

[0044] The second implementation method:

[0045] Figures 2 - 4 and Figure 9 As shown in the signal interference device 1, a plurality of drone control devices 3 are installed on the signal interference device 1. The plurality of drone control devices 3 each include a signal transfer device 6 and an antenna main body 7, and the signal transfer device 6 is threadedly connected to the antenna main body 7. The drone control device 3 is signal-connected to the signal interference device 1 through the signal transfer device 6. An additional outer shell 8 is sleeved on one side of the signal transfer device 6 close to the antenna main body 7. A sealing cover 10 matching itself is threadedly connected to the opening at one end of the additional outer shell 8 close to the antenna main body 7. A fixed base 13 matching itself is fixedly connected inside the additional outer shell 8. An indentation groove is dug at the upper end of the fixed base 13 on the side close to the signal transfer device 6. An emergency unit 12 is fixedly connected to the lower end of the sealing cover 10, and the sealing cover 10 and the emergency unit 12 are fixedly connected by hot melt adhesive. The emergency unit 12 includes a glass ring 1201. An electric heating mesh 1203 is fixedly connected to the inner wall of the glass ring 1201. A hot melt adhesive 1202 is filled in the glass ring 1201. A plurality of corrosion balls 1204 are filled in the hot melt adhesive 1202, and the corrosion balls 1204 and the hot melt adhesive 1202 do not react with each other. The density of the hot melt adhesive 1202 is less than that of the corrosion balls 1204.

[0046] Specifically, in this application, the start switch of the electric heating mesh 1203 is independent of the start switch of the signal interference device 1.

[0047] The network performance test of the wireless ad-hoc network communication device in this embodiment is carried out following the first embodiment. During the interference test, once the working data of the drone control device 3 and the drone main body 4 received by the output display device 2 matches the limit working data, the signal interference device 1 is immediately shut down and the heating grid 1203 is started, stopping the electromagnetic interference on the drone control device 3 and the drone main body 4, so that the working states of the drone control device 3 and the drone main body 4 are restored. At this time, since the signal interference device 1 is shut down, the heating grid 1203 loses power supply and cannot be started.

[0048] However, when the signal interference device 1 experiences program lag due to long-term testing or high-power testing and cannot immediately shut down, the heating grid 1203, under the power supply of the signal interference device 1, quickly heats up to completely melt the hot melt adhesive 1202. Then the temperature continues to rise until the connection between the glass ring 1201 and the sealing cover 10 fails, and it drops along the signal transfer device 6 and collides with the fixed base 13, causing the glass ring 1201 to break. The heating grid 1203 will also fail accordingly, and the hot melt adhesive 1202 and the corrosion ball 1204 will be released. Due to the density difference between the two, a layer will be formed with the hot melt adhesive 1202 on top and the heating grid 1203 at the bottom. At this time, the heating grid 1203 will corrode the signal transfer device 6, damage the signal transfer device 6, cut off the connection between the antenna main body 7 and the signal interference device 1, and the antenna main body 7 can no longer generate interference electromagnetic waves, stopping the electromagnetic interference on the drone control device 3 and the drone main body 4. As the hot melt adhesive 1202 and the corrosion ball 1204 cool down, the hot melt adhesive 1202 will re-solidify, sealing the remaining corrosion ball 1204 between the hot melt adhesive 1202 and the fixed base 13, avoiding the leakage of the corrosion ball 1204 and not easily causing secondary pollution.

[0049] The filling amount of the hot melt adhesive 1202 is two-thirds of the volume inside the glass ring 1201, making the glass ring 1201 more likely to break when it falls.

[0050] In this application, the additional outer shell 8 and the internal structural design transfer the possible damage to the drone control device 3 and the drone main body 4 during the electromagnetic interference test of the wireless ad-hoc network communication device to the signal transfer device 6 with lower cost, reducing the cost of the electromagnetic interference test process of the wireless ad-hoc network communication device.

[0051] In this embodiment, the corrosion ball 1204 is wrapped by the hot melt adhesive 1202 before the emergency unit 12 is started, and after the emergency unit 12 is started and becomes effective, it is jointly wrapped by the solidified hot melt adhesive 1202 and the fixed base 13, which can effectively prevent the leakage of the corrosion ball 1204 and reduce the risk of secondary pollution.

[0052] And the production method of the emergency unit 12 is as Figure 10As shown, first, hot melt adhesive 1202 and hollow elastic balls are injected into a mold with the same size as the glass ring 1201, and a same-polarity magnetic coating is coated on the surface of the hollow elastic balls to make multiple hollow elastic balls evenly distributed in the hot melt adhesive 1202. After the hot melt adhesive 1202 is solidified, a syringe is used to inject corrosion balls 1204 into the hollow elastic balls to corrode the hot melt adhesive 1202. After all the corrosion balls 1204 are injected, hot melt adhesive 1202 is injected again to seal the injection channel formed by the syringe. After demolding, a material matching the size of the glass ring 1201 can be obtained, and the upper part of the glass ring 1201 can be designed as a threaded upper cover to facilitate the installation of the emergency unit 12.

[0053] In order to facilitate the injection and demolding work, the mold and the hot melt adhesive 1202 need to be made of colorless and transparent materials. Before the hot melt adhesive 1202 is prepared, a matching separation film that does not react with the hot melt adhesive 1202 needs to be laid inside the mold.

[0054] See also Figures 4 - 6 The additional shell 8 includes a shell 801, and a plurality of installation grooves 802 are bored at the upper end of the shell 801. The plurality of installation grooves 802 are all plugged with heat dissipation units 9 matching themselves, thereby increasing the heat exchange efficiency on both sides of the additional shell 8, and preventing excessive heat from accumulating in the signal switching device 6 and causing irreversible damage to the signal interference device 1. A heat dissipation groove is bored at one end of the heat dissipation unit 9 located on the outer side of the additional shell 8, which increases the specific surface area of ​​the heat dissipation unit 9 on the one hand, and increases the friction force on the other hand, thereby facilitating the plug-in and installation of the heat dissipation unit 9.

[0055] A plurality of air holes 803 are drilled on the side wall of the additional shell 8, and the plurality of air holes 803 are all located in the upper half of the shell 801. The existence of the air holes 803 can realize air exchange with the outside, avoid the accumulation of excessive high-pressure gas in the additional shell 8, and is not likely to cause the shell 801 to rupture, and is not likely to cause corrosion ball 1204 leakage accidents.

[0056] See also Figure 7 A plurality of disassembly grooves are formed at the upper end of the sealing cover 10 , and the depth of the disassembly grooves is less than half of the sealing cover 10 , thereby reducing the impact on the structural strength of the sealing cover 10 and facilitating the installation and disassembly of the sealing cover 10 .

[0057] See also Figure 4 and Figure 8, a protective curtain 11 is fixedly connected to the lower end of the sealing cover 10. The protective curtain 11 is sleeved outside the emergency unit 12. The protective curtain 11 can buffer the fragments of the emergency unit 12 to prevent the fragments of the emergency unit 12 from directly damaging the additional housing 8. The protective curtain 11 includes a fine mesh curtain 1101, and the fine mesh curtain 1101 is a net structure woven from elastic fibers, which increases the buffering effect and impact resistance of the protective curtain 11. One end of the fine mesh curtain 1101 away from the sealing cover 10 is fixedly connected with a plurality of counterweight blocks 1102, and the counterweight blocks 1102 shift in position when the fine mesh curtain 1101 is impacted by the fragments of the emergency unit 12. Without affecting the buffering effect of the fine mesh curtain 1101, the counterweight blocks 1102 can quickly restore the fine mesh curtain 1101 and quickly resume the buffering effect.

[0058] Compared with the first embodiment, in this embodiment, during the electromagnetic interference test, when the electromagnetic interference received by the drone control device 3 and the drone body 4 reaches the limit, the output display device 2 can be directly shut down through the signal interference device 1 to stop the electromagnetic interference. When the signal interference device 1 freezes due to long-term testing or high-power testing, the hot melt adhesive 1202 is activated to damage the signal transfer device 6 and cut off the connection between the antenna main body 7 and the signal interference device 1. The antenna main body 7 can no longer generate interfering electromagnetic waves, and the electromagnetic interference on the drone control device 3 and the drone body 4 is stopped. Through the additional housing 8 and the internal structural design, the possible damage to the drone control device 3 and the drone body 4 during the electromagnetic interference test of the wireless ad hoc network communication device is transferred to the signal transfer device 6 with lower cost, reducing the cost of the electromagnetic interference test of the wireless ad hoc network communication device.

[0059] Combined with the current actual requirements, the above embodiments adopted in this application are not limited to this scope. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
