[0025] The following is combined with Figure 1 - Attachment Figure 3 The present invention is described in further detail.

[0026] Example 1: Reference Figure 1 - Figure 3 , a networked drone 1 display screen 31 for traffic command, a bracket 2 is arranged below the drone 1, a display component 3 is arranged in front of the bracket 2, the display component 3 includes a display screen 31, a drive module 32 and a 4G module 33, and the drive module 32 is responsible for processing various input data (such as data transmitted from a mobile phone APP, a traffic command center server, etc. through a 4G module 33, a WIFI module or a USB interface) to convert it into a format suitable for display on the display screen 31. For example, text information, image data, charts, etc. are converted into pixel signals that can be recognized by the display screen 31 to ensure that the information can be accurately and clearly presented on the display screen 31. If the input data is a high-definition image, but the resolution of the display screen 31 is a specific 64*16 (composed of two display panels with a resolution of 32*16), the drive module 32 will scale, crop, and process the image to achieve the best display effect under a limited resolution.

[0027] For dynamic display content, such as scrolling subtitles, flashing signs, etc., the driver module 32 processes the data according to the preset display mode parameters (such as scrolling speed, flashing frequency, etc.), and generates corresponding control signals to control the lighting order and time interval of the pixels of the display screen 31, so as to realize the display of dynamic effects. For example, when displaying traffic information, the driver module 32 can process the real-time updated traffic data into the form of scrolling subtitles, so that the driver can obtain information in time. The driver module 32 and the 4G module 33 are installed on the back of the display screen 31, and are connected to the display screen 31. The 4G module 33 is equipped with a traffic card to provide network access and data transmission services for the 4G module 33, so as to realize remote data transmission and control through the mobile phone APP. The user needs to download and install the corresponding APP on the mobile phone first, and then register the account through the mobile phone number. After successful registration, the IMEI code of the display and the 4G module 33 is used to add the device to complete the pairing connection between the APP and the display component 3. In the APP, users can easily input various traffic control related display contents, such as traffic sign patterns (such as no-traffic signs, turn signs, etc.), instruction texts (such as road closure notices, speed limit prompts, etc.), and can set the display mode (such as text scrolling speed, dwell time, font size, color, etc.) in detail. You can also choose different display effects, such as flashing, gradient, etc., to attract the attention of road users and improve the communication effect of traffic control information. According to the changes in ambient light or user settings, the driver module 32 can adjust the brightness and contrast of the display screen 31. In the daytime strong light environment, the driver module 32 automatically increases the brightness of the display screen 31 to make the displayed content clearly visible; at night or in low light environments, the brightness is reduced to avoid glare, and the contrast is increased to enhance the distinction between the displayed content and the background. For example, during night traffic control, appropriately reducing the brightness and increasing the contrast can enable the driver to see the traffic control information on the display screen 31 without being disturbed by strong light.

[0028] The modification of the content of the display screen 31 can also be controlled by WIFI and USB. The driver module 32 is provided with a WIFI module and a USB interface to provide a suitable communication mode to adapt to different scene requirements. When using WIFI control, the WIFI module in the display component 3 will search for available WIFI networks around. After the user connects to the same WIFI network on the control device (such as a computer, tablet computer, etc.), the display content can be modified and set through a special control software. USB control connects it to a computer or other device through the USB interface on the display component 3, runs the corresponding control program, and realizes the editing and management of the display content. This multi-control mode design allows operators to choose the most convenient and most suitable control means according to actual conditions in different usage scenarios. For example, during on-site traffic command, traffic police can use mobile phone APP to modify the display content anytime and anywhere; when the traffic command center is centrally managed and dispatched, staff can use a computer to use WIFI or USB connection to perform more complex and comprehensive display content editing and control.

[0029] The driver module 32 works closely with the 4G module 33 and the WIFI module to receive remote data transmitted from these modules. When the 4G module 33 or the WIFI module receives new information sent by the traffic command center, the driver module 32 will promptly obtain and process the data and convert it into display content. At the same time, it can also feedback the working status information of the display screen 31 to the 4G module 33 or the WIFI module, such as whether it is displayed normally, whether data is received, etc., so as to facilitate remote monitoring and management. For example, if the display screen 31 fails and cannot display normally, the driver module 32 can send the fault information back to the command center through the 4G module 33 so that maintenance can be arranged in time.

[0030] When an external device (such as a computer) is connected via a USB interface for data update or debugging, the driver module 32 is responsible for data transmission and interaction with the computer. It receives display data, control instructions, etc. sent by the computer, and feeds back relevant information of the display screen 31 (such as resolution, current display mode, etc.) to the computer. When updating the firmware or driver of the display screen 31, the driver module 32 coordinates the reception and writing of data to ensure the smooth progress of the update process.

[0031] The display assembly 3 also includes a frame 34 fixedly connected to the back of the display screen 31, and the back of the frame 34 is bolted fixedly connected with a carbon plate 35. The display body is composed of two display panels with a resolution of 32*16, which are reinforced with a 2mm carbon fiber plate. The carbon fiber plate has 12 screw fixing eyes, 1 external power supply line, 1 antenna wiring eye, 2 Picatinny rail fixing eyes, and the battery block is removed and bonded with 3m glue.

[0032] The drive module 32 and the 4G module 33 are both embedded in the inner side of the frame 34, and the drive board and the 4G module 33 of the display are placed in the groove formed in the inner side of the frame 34. This embedded design can not only effectively protect the drive module 32 and the 4G module from external physical damage, but also make the internal structure of the display more compact and reduce space occupation. The wiring in the middle of the display is passed through holes to reduce the thickness of the display, making the entire display assembly 3 lighter, which is beneficial to the flight performance and endurance of the drone 1.

[0033] The display assembly 3 is provided with a detachable energy supply module on the outside; the energy supply module includes a slide 61, a slider 62 and a battery pack 63. The slide 61 is bonded to the back of the display assembly 3. The slider 62 and the battery pack 63 are tied by an elastic rope 64. The sliders 62 and 62 are slidably fitted with each other. The battery pack 63 supplies energy to the display assembly 3 through a cable. The battery pack 63 is three lithium batteries connected in series, and the full-charge voltage is 12.6V. Both sides of the slider 62 are integrally formed with buckles, and the two ends of the elastic rope 64 are respectively embedded in the two buckles. The force of the buckle on the elastic rope 64 is opposite to the force of the battery pack 63 on the elastic rope 64, so that the position of the battery after bundling can be ensured to be stable. During installation, the slider 62 is first slidably embedded on the slide 61, and then the battery pack 63 and the display assembly 3 are electrically connected through a cable to ensure that the power can be smoothly transmitted to the display assembly 3, so that the display screen 31 lights up and works normally. This design facilitates the installation and removal of the battery pack 63. When the battery needs to be replaced or maintained, the operator can easily untie the elastic rope 64, remove the battery pack 63 from the slider 62, and reinstall it after performing corresponding operations.

[0034] The display component 3 is installed on the bracket 2 of the drone 1 through a detachable structure; both sides of the back of the display component 3 are fixedly connected to the Picatinny rail 2 51 by bolts, and the outer side of the Picatinny rail 2 51 is provided with a plug-in block 52 that matches it, and the plug-in block 52 is fixedly connected to the bracket 2 through a strap 53, and the plug-in block 52 is provided with bolts that match the Picatinny rail 2 51 to complete the limiting of the slider 62, so as to ensure the stability of the position after insertion.

[0035] The bracket 2 is in a "T"-shaped structure, and the top of the bracket 2 is connected to the bottom of the drone 1 through the Picatinny rail 4. The bracket 2 has an inclination angle of 40°, which can be compatible with the DJI M300\M350 series. The size of the bracket 2 is 63*60cm horizontally and vertically. Its larger size provides enough space for the display component 3, so that it can be reasonably arranged and will not be affected by space restrictions and affect the function. At the same time, the inclination angle of 40° is obtained after multiple experiments and simulation optimizations, which can not only ensure that the display screen 31 is within the optimal viewing angle range for ground personnel to watch traffic command information, but also minimize the impact on the flight performance and stability of the drone 1, ensuring that the drone 1 can run smoothly during the flight, and will not have problems such as imbalance and jitter due to the installation of the display component 3. The Picatinny rail 4 is installed at the bottom of the drone 1, and the top of the bracket 2 is provided with a plug-in block 52 that matches the Picatinny rail 4, and the plug-in fixation between the plug-in block 52 and the Picatinny rail 4 is achieved by bolts on the plug-in block 52.

[0036] Check the display effect of the display screen 31 regularly to see if there are any dead pixels, bright pixels or uneven display. If any problems are found, the display screen 31 can be tested using professional testing software. After the problem is determined, repair or replace the display panel according to the specific situation. At the same time, check if there are any scratches or stains on the surface of the display screen 31. If necessary, clean and maintain it in time to ensure the clarity and visibility of the display screen 31.

[0037] Perform regular inspections on the driver module 32 and the 4G module to ensure that they are working properly. You can connect the test equipment to check whether the parameters such as signal transmission strength and data processing speed are within the normal range. If a module failure is found, repair or replace it in time. For the traffic card of the 4G module, pay attention to the traffic usage and recharge it in time to ensure that the device can connect to the network normally for data transmission.

[0038] Check the connection parts of the display assembly 3, such as whether the screws are loose, whether the Picatinny rail and the plug block 52 are worn, etc. If the connection parts are found to be loose or damaged, tighten or replace them in time to ensure the installation stability of the display assembly 3 on the drone 1.

[0039] Regularly check the battery pack 63's power and health. You can use professional battery testing equipment to test the battery's voltage, internal resistance and other parameters to determine whether the battery needs to be charged or replaced. When charging, use the matching charger and follow the correct charging method to avoid damage to the battery due to overcharging, over-discharging and other situations.

[0040] Check the working status of the elastic cord 64 and the slider 62 to ensure that the elastic cord 64 is not broken or aged, and that the slider 62 can slide smoothly on the slide seat 61. If there is a problem with the elastic cord 64, replace it with a new one in time; if the slider 62 does not slide smoothly, clean the debris between the slider 62 and the slide seat 61 and add a proper amount of lubricant to ensure that the battery pack 63 can be installed and removed conveniently and quickly, and remain stable during flight.
