[0023] In this embodiment of the invention, the drone signal may include drone remote identification information, which may include drone identification, drone real-time status, drone location, and other information.

[0024] In this embodiment of the invention, the first drone signal, the second drone signal, and the third drone signal can be emitted by the drone itself or by a drone signal simulator. The specific source of transmission is not specifically limited here.

[0025] In this embodiment of the invention, the first drone signal, the second drone signal, and the third drone signal can be three wireless radio frequency signals using different communication protocols.

(This is repeated four times in the original text.) For example, the first drone signal can be a Bluetooth drone signal, the second drone signal can be a 2.4G band Wi-Fi drone signal, and the third drone signal can be a 5.8G band Wi-Fi drone signal. It should be understood that the above is only an example of three wireless radio frequency signals with different communication protocols, and is not intended to limit the present invention.

[0026] In this embodiment of the invention, a drone signal receiver can receive and parse drone signals with different communication protocols sent by different types of drones, and send the received drone signals to external electronic devices after parsing, thereby realizing the monitoring of drones.

[0027] In this embodiment of the invention, the external electronic device can be a server, desktop computer, laptop computer, or other electronic device. The external electronic device can serve as an external monitoring platform, thereby enabling the monitoring of the drone through the parsed drone signals transmitted by the drone signal receiver.

[0028] In this embodiment of the invention, the specific workflow of the UAV signal receiver during UAV signal transmission is as follows: The third communication module 13 receives and parses the third UAV signal sent by the UAV, and then sends the parsed third UAV signal to the second communication module 12. The second communication module 12 receives and parses the second UAV signal sent by the UAV and the parsed third UAV signal, and then sends both the parsed second and third UAV signals to the first communication module 11. The first communication module 11 receives and parses the first UAV signal sent by the UAV, and the parsed second and third UAV signals, and then sends these signals to an external electronic device. This enables the transmission and external distribution of UAV data using different communication protocols.

[0029] In this embodiment of the utility model, the first communication module 11 not only undertakes the task of receiving and parsing the first UAV signal, but also serves as the control center of the UAV signal receiver, managing and controlling other communication modules to realize the external transmission of UAV data.

[0033] In the field of drones, there are many drones broadcasting 2.4G band Wi-Fi drone signals. Therefore, the amount of 2.4G band Wi-Fi drone signal data received by drone signal receivers is relatively large. In order to improve the stability of data reception, in this embodiment of the utility model, the first communication module of the drone signal receiver is set to receive 2.4G band Wi-Fi drone signals, thereby enabling the first communication module to receive 2.4G band Wi-Fi drone signals more stably.

[0034] In this embodiment of the invention, the first communication module 11 can be an Espressif ESP8266, Espressif ESP32 series, Espressif ESP32-S series, Espressif ESP32-C series, or similar communication module to receive 2.4GHz Wi-Fi drone signals. The second communication module 12 can be a communication module with Bluetooth signal transceiver capabilities, such as an Espressif ESP32 series, Espressif ESP32-S series, Espressif ESP32-C series, or similar communication module to receive Bluetooth drone signals. The third communication module 13 can be an Espressif ESP32 series, Espressif ESP32-S series, Espressif ESP32-C series, Ai-Thinker BW16, or similar communication module to receive 5.8GHz Wi-Fi drone signals. It should be understood that the above is only one of the multiple options for the first communication module 11, the second communication module 12, and the third communication module 13, but it is not limited to this. The present invention can also flexibly select and match the first communication module 11, the second communication module 12, and the third communication module 13 according to the actual application scenario.

[0035] In some embodiments of this utility model, such as Figure 1 and 2As shown, the first communication module 11 of the UAV signal receiver 10 may include a first interface 111 and a second interface 112. The second communication module 12 may include a first interface 121, a second interface 122, and a third interface 123. The third communication module 13 may include a first interface 131 and a second interface 132. The first interface 111 of the first communication module is connected to an external electronic device for receiving a first UAV signal and transmitting the parsed first UAV signal and the signal received by the second interface 112 to the external electronic device. The second interface 112 of the first communication module 11 is connected to the second interface 122 of the second communication module 12. The first interface 121 of the second communication module 12 is used to receive a second UAV signal. The second interface 122 of the second communication module 12 is connected to the second interface 112 of the first communication module 11 to send the parsed second UAV signal and the signal received by the third interface 123 to it. The third interface 123 of the second communication module 12 is connected to the second interface 132 of the third communication module 13 to receive the parsed third UAV signal from it. The first interface 131 of the third communication module 13 is used to receive a third UAV signal.

[0036] In this embodiment of the present invention, a third UAV signal can be received through the first interface 131 of the third communication module 13, and the third UAV signal can be parsed through a corresponding module, such as a wireless radio frequency transceiver module, inside the third communication module. After parsing, the parsed third UAV signal can be sent to the second communication module 12 through the second interface 132 of the third communication module 13.

[0037] The third interface 123 of the second communication module 12 can receive the parsed third UAV signal sent by the third communication module 13, and send the parsed third UAV signal to the first communication module 11 through the second interface 122 of the second communication module 12.

[0038] The second UAV signal can be received through the first interface 121 of the second communication module 12, and the second UAV signal can be parsed inside the second communication module. The parsed second UAV signal can then be sent to the first communication module 11 through the second interface 122 of the second communication module 12.

[0039] The second interface 112 of the first communication module 11 can receive the parsed third UAV signal and the parsed second UAV signal sent by the second communication module 12, and send the third UAV signal and the second UAV signal to external electronic devices.

[0040] The first communication module 11 can receive the first drone signal through its first interface 111, and parse the first drone signal inside the first communication module and send the parsed first drone signal to an external electronic device.

[0041] This utility model embodiment achieves a serial communication module connection structure through the above solution, which can reduce the resource occupation of the first communication module by other communication modules, alleviate the processing pressure of the first communication module on the UAV signal, and improve the processing speed and transmission speed of the first communication module on the UAV signal.

[0043] In this embodiment of the invention, by connecting the first communication module 11 and the second communication module 12, and the second communication module 12 and the third communication module 13, through a universal asynchronous transceiver, the anti-interference capability of the UAV signal receiver when transmitting UAV signals internally is improved, and the accuracy of UAV signal transmission is improved.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the UAV signal receiver 10 may also include a wireless network module 14.

[0046] In this embodiment of the utility model, the wireless network module 14 can be a 4G network card, 5G network card or other wireless network module, thereby enabling the parsed drone signal to be sent to external devices in real time through the network, thus improving the real-time performance of drone data transmission.

[0047] In this embodiment of the invention, the wireless network module 14 can transmit the parsed drone signal to external electronic devices via the network, improving the real-time performance of drone data transmission. If a drone violates regulations during flight, it can be detected in a timely manner, and appropriate measures can be taken.

[0048] In some embodiments of this utility model, such as Figure 2 As shown, the UAV signal receiver 10 may also include a wired network module 15, and the first communication module 11 and the wired network module 15 may be connected via SPI (Serial Peripheral Interface).

[0049] In this embodiment of the invention, the first communication module 11 can also send the parsed drone signal to an external electronic device through the wired network module 15, thereby improving the real-time performance of drone data transmission and enabling timely detection of drones flying in violation of regulations, thus allowing timely measures to be taken.

[0050] In this embodiment of the invention, the first communication module 11 and the wired network module 15 can be connected via SPI, thereby improving the UAV signal transmission rate between the first communication module 11 and the wireless network module 15.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the UAV signal receiver 10 may also include a network interface 16, which is connected to the wired network module 15.

[0052] This network interface 16 allows the drone signal receiver to be directly connected to external devices via a network cable. For example, the network interface can be an RJ45 network interface, a PoE / RJ45 network interface, etc.

[0053] In some embodiments of this utility model, such as Figure 2 As shown, the UAV signal receiver 10 may also include a power supply (not shown). The power supply can power other modules in the UAV signal receiver.

[0054] In some embodiments of this utility model, such as Figure 3 As shown, the UAV signal receiver 10 includes, in addition to the first communication module 11, the second communication module 12, and the third communication module 1 connected in sequence, a fourth communication module 17 connected between the first communication module 11 and the second communication module 12. The fourth communication module 17 is used to receive a fourth UAV signal, which may use the same communication protocol as the first UAV signal.

[0055] In this embodiment of the invention, the specific workflow of the UAV signal receiver during UAV signal transmission is as follows: The third communication module 13 receives and parses the third UAV signal sent by the UAV, and sends the parsed third UAV signal to the second communication module 12. The second communication module 12 receives and parses the second UAV signal sent by the UAV and receives the parsed third UAV signal, and sends both the parsed second and third UAV signals to the fourth communication module 17.

[0056] The fourth communication module 17 receives and parses the fourth UAV signal sent by the UAV, as well as the parsed second and third UAV signals, and sends the parsed second, third, and fourth UAV signals to the first communication module 11.

[0057] The first communication module 11 receives and parses the first drone signal sent by the drone, as well as the parsed second drone signal, the parsed third drone signal, and the parsed fourth drone signal, and sends the parsed first drone signal, the parsed second drone signal, the parsed third drone signal, and the parsed fourth drone signal to an external electronic device.

[0058] In this embodiment of the utility model, the first communication module 11 not only undertakes the task of receiving and parsing the first UAV signal, but also serves as the control center of the UAV signal receiver, managing and controlling other communication modules to realize the external transmission of UAV data.

[0059] On the one hand, the present invention, through the above-described solution, realizes a serial communication module connection structure, which can not only identify UAV signals with multiple different communication protocols at the same time, but also reduce the resource occupation of the first communication module by other communication modules, alleviate the processing pressure of the first communication module on UAV signals, and improve the processing speed and transmission speed of the first communication module on UAV signals.

[0060] On the other hand, in this embodiment of the invention, by receiving and parsing drone signals with the same communication protocol through the first communication module and the fourth communication module, it is possible to avoid missing identification of drone signals with the same communication protocol, improve the reception rate of the drone signal receiver for the drone signal, and improve the integrity of the drone signal, thereby enabling external electronic devices to better monitor the status of the drone.

[0061] In some embodiments of this utility model, such as Figure 3As shown, the UAV signal receiver may further include: a first external antenna connected to the first communication module 11 and a second external antenna connected to the fourth communication module 17, wherein the first external antenna and the second external antenna are installed at a preset angle.

[0062] In this embodiment of the present invention, the first communication module 11 and the fourth communication module 17 are disposed inside the receiver housing, and the first external antenna and the second external antenna are disposed outside the receiver housing. The first communication module 11 and the first external antenna are connected through a radio frequency interface disposed on the receiver housing, and the fourth communication module 17 and the second external antenna are connected through a radio frequency interface disposed on the receiver housing.

[0063] In this embodiment of the invention, by setting the installation directions of the first external antenna and the second external antenna to a preset angle, the first communication module 11 and the fourth communication module 17 can receive drone signals sent by the drone in different directions. For example, the installation directions of the first and second external antennas can be 90° apart, that is, the installation directions of the first and second external antennas are perpendicular to each other. However, this is not a limitation; in other embodiments, the installation directions of the first and second external antennas can be set to other angles.

[0064] In this embodiment of the invention, by setting the installation direction of the first external antenna and the second external antenna to a preset angle, not only can the sensing range of the UAV signal receiver for UAV signals with the same communication protocol that can be received by the first communication module and the fourth communication module be improved, but the repeated reception of the UAV signal can also be reduced to a certain extent.

[0065] In some embodiments of this utility model, such as Figure 3 As shown, the fourth communication module 17 of the UAV signal receiver 10 may include a first interface 171, a second interface 172 and a third interface 173. The first interface 171 of the fourth communication module 17 may be a radio frequency interface for receiving signals from the fourth UAV. The second interface 172 and the third interface 173 of the fourth communication module 17 may be UART interfaces. The second interface 172 of the fourth communication module 17 may be connected to the first communication module 11, and the third interface 173 of the fourth communication module 17 may be connected to the second communication module 12.

[0066] More specifically, the second interface 112 of the first communication module 11 can be connected to the second interface 172 of the fourth communication module 17, and the third interface 173 of the fourth communication module 17 can be connected to the second interface 122 of the second communication module 12. The connection methods of the other interfaces of the first communication module 11, the other interfaces of the second communication module 12, and the interfaces of the third communication module are the same. Figure 2The connection methods of the corresponding modules and their interfaces in the drone signal receivers shown are the same, so they will not be described in detail here.

[0067] In this embodiment of the invention, by receiving drone signals with the same communication protocol through the first communication module and the fourth communication module, the omission of drone signals with the same communication protocol can be avoided, the reception rate of the drone signal receiver for the drone signal can be improved, and the integrity of the drone signal can be improved, thereby enabling external electronic devices to better monitor the status of the drone.

[0068] The following description, in conjunction with specific examples, illustrates the UAV signal receiver provided in the embodiments of this utility model. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0069] like Figure 4 As shown, the UAV signal receiver 40 includes: a first communication module 41, a fourth communication module 42, a second communication module 43 and a third communication module 44 connected in series, and any two communication modules are connected by UART. The first communication module 41 is also connected to a wireless network module 45 and an Ethernet communication module 46, and the Ethernet communication module 46 is also connected to a POE / RJ45 network interface 47.

[0070] In this example, the first communication module 41 serves as a 2.4G+ main control communication module, used for transmitting, receiving, and parsing 2.4G drone signals, and as the main control chip, it enables the external transmission of drone signals using different communication protocols. The second communication module 43 serves as a Bluetooth communication module, used for transmitting, receiving, and parsing Bluetooth signals. The third communication module 44 serves as a 5.8G communication module, used for transmitting, receiving, and parsing 5.8G drone signals. The fourth communication module 42 serves as a 2.4G communication module, used for transmitting, receiving, and parsing 2.4G drone signals. The wireless network module 45 uses a 4G chip to transmit the parsed drone signals sent by the first communication module 41 to an external monitoring platform via the 4G network. The Ethernet module 46 uses an Ethernet chip and connects to the PoE / RJ45 network interface 47 via MDI (Media Dependent Interface).

[0071] The above-described solution of this utility model, by serially connecting the first communication module 41, the fourth communication module 42, the second communication module 43, and the third communication module 44, and using the first communication module 41 as the control center, realizes the external transmission of UAV data with different communication protocols. This achieves a UAV signal receiver that can simultaneously identify 2.4G UAV signals, 5.8G UAV signals, and Bluetooth signals, reducing the resource occupation of the first communication module 41 and improving the speed of external data transmission of the first communication module 41.

[0072] Through the above-described solution, this invention can also reduce the missed identification of 2.4G drone signals, improve the reception rate of 2.4G drone signals by drone signal receivers, and improve the integrity of 2.4G drone data, thereby enabling external monitoring platforms to better monitor the status of drones.
