[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 9 .

[0023] A passive positioning drone detection device based on multi-band detection comprises a base station, the base station comprises a shell 1, a signal processing module 2, a data storage module 4 and a multi-band multi-mode detection receiving module 5 are arranged in the shell 1, a display 3 is installed on the side of the shell 1; a solar cell 6 is also connected to the outer side of the shell 1; the signal processing module 2 is respectively connected to the solar cell 6, the data storage module 4, the display 3 and the multi-band multi-mode detection receiving module 5; the multi-band multi-mode detection receiving module 5 comprises a 2.4GHz frequency band receiving module, a 5.8GHz frequency band receiving module, a Bluetooth frequency band receiving module and a multi-mode detection module; the utility model receives 2.4G through the 2.4GHz frequency band receiving module, the 5.8GHz frequency band receiving module and the Bluetooth frequency band receiving module Hz band, 5.8GHz band and Bluetooth band for drone signals for communication; among them, the 2.4GHz band is one of the most commonly used frequency bands in wireless communications. Many drones use this frequency band for communication. The 2.4GHz band receiving module of the base station can accurately scan this frequency band and capture weak drone signals; the 5.8GHz band has a longer signal transmission distance and stronger penetration ability than the 2.4GHz band. Some high-end drones may use this frequency band for communication, so the base station receiver also needs to support this frequency band; Bluetooth band, Bluetooth technology is widely used in short-distance communications between various electronic devices, including drones. The base station receiver can identify and process these Bluetooth signals, thereby achieving accurate positioning of the drone.

[0024] As for the multi-mode detection module, drones of different manufacturers and models may adopt different communication protocols and signal formats. The multi-mode detection reception technology enables the base station to be compatible with and identify these diverse signals, no matter which brand or model the drone comes from. At the same time, by legally and compliantly collecting and analyzing drone signal data, it can provide valuable intelligence information for relevant departments, such as combating illegal activities and protecting sensitive facilities. The utility model has a stronger receiving capability through 2.4GHz frequency band receiving module, 5.8GHz frequency band receiving module, Bluetooth frequency band receiving module and multi-mode detection module, which greatly enhances the applicability and receiving capability of the base station in complex environments and reduces the risk of false alarms and missed alarms.

[0025] The signal processing module 2 is used for signal processing and data analysis. Once the drone signal is received, the signal processing module 2 of the base station will perform a series of signal processing operations, such as filtering, amplification and demodulation, to extract useful information; this information may include the drone's position, speed, flight status and communication content with the remote control, etc. Through in-depth analysis of these data, the dynamics and behavior patterns of the drone can be more accurately judged.

[0026] The display 3 is used for real-time information processing and display. Once the message from the drone is received, the signal processing module 2 built into the base station will immediately decode the data and update the drone's serial number (SN code), current position (latitude and longitude), flight altitude, heading, speed, flight trajectory and other information in real time. In addition, the system can also track the real-time position and altitude of the pilot; as a preferred embodiment, the utility model can configure a user-friendly interface in the display 3, so that the base station is equipped with a more intuitive user interface, which can be a touch screen or a control panel accessed through a web page, so that users can view and control the various functions of the base station. Users can adjust parameters, set alarm thresholds, and monitor the real-time status of the drone through the interface.

[0027] As for the battery, the utility model uses a solar cell 6. In order to adapt to the outdoor environment and reduce the dependence on traditional power sources, the present invention uses the solar cell 6 as the main energy source. The solar cell 6 converts sunlight into electrical energy and stores it in itself for use by the base station, ensuring the continuous operation of the equipment in areas without grid coverage.

[0028] The utility model also designs a data storage module 4, which is provided with a USB interface. The data storage module 4 is used for data recording and can save the flight history data of the UAV. These data can be exported through the USB interface for further analysis and investigation. For example, the data analysis tool can help users understand the flight mode, behavior habits, and performance of the UAV in specific events.

[0029] A heat dissipation port 7 is provided on the side of the shell 1, and a rain shield frame 8 is installed on the heat dissipation port 7 of the shell 1; specifically, a locking device is connected in the rain shield frame 8, and the locking device includes two clamping blocks 9 and an adjusting rod rotatably connected in the rain shield frame 8; the two clamping blocks 9 are respectively connected to the two sides of the heat dissipation port 7 in a longitudinal sliding manner, and the adjusting rod includes a front longitudinal screw 10 and a rear longitudinal screw 11 connected to the front longitudinal screw 10, and the front longitudinal screw 10 and the rear longitudinal screw 11 rotate in opposite directions, and the front longitudinal screw 10 and the rear longitudinal screw 11 rotate in opposite directions, and the front longitudinal screw 10 and the rear longitudinal screw 11 rotate in opposite directions. Coaxial; the two clamping blocks 9 are respectively threadedly connected with the front longitudinal screw 10 and the rear longitudinal screw 11; the adjusting rod controls the two clamping blocks 9 to move longitudinally in the opposite direction by rotating itself, so that the two clamping blocks 9 are respectively clamped on the front and rear sides of the heat dissipation port 7; more specifically, three heat dissipation ports 7 are opened on the side of the shell 1, and the clamping blocks 9 are longitudinally slidably connected to the three heat dissipation ports 7; the front end of the front longitudinal screw 10 passes through the rain shield frame 8 and is connected to the first turning handle 21, and the rear end of the rear longitudinal screw 11 passes through the rain shield frame 8 and is connected to the second turning handle 22.

[0030] The utility model can effectively prevent rainwater from directly entering the housing 1 from the heat dissipation port 7 by setting a rain shield frame 8 at the heat dissipation port 7, thereby avoiding damage to components in the housing 1. Specifically, in the installation of the rain shield frame 8, the utility model rotates the first turning handle 21 or the second turning handle 22 to rotate the front longitudinal screw 10 and the rear longitudinal screw 11. Since the two clamping blocks 9 are respectively threadedly connected to the front longitudinal screw 10 and the rear longitudinal screw 11, when the front longitudinal screw 10 and the rear longitudinal screw 11 are rotated, the front longitudinal screw 10 and the rear longitudinal screw 11 control the two clamping blocks 9 to move longitudinally in the opposite direction until the two clamping blocks 9 are respectively clamped on the front and rear sides of the heat dissipation port 7 (reference Figure 3 , 4 , 5), at this time the rain shield frame 8 is installed. The utility model adopts the above structure to install the rain shield frame 8, which is more convenient.
