Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anti-icing technology, and specifically relates to an anti-icing system for unmanned aerial vehicles (UAVs). Background Technology
[0002] Currently, drones have played a significant role in various fields. However, when drones fly, they often need to pass through clouds or other potentially icy weather conditions. Due to the lack of effective anti-icing and de-icing measures, icing on the wings or engine lips of drones can have serious consequences. Therefore, there is an urgent need for a system-level solution to prevent and de-ic the wings and engine lips of drones. Utility Model Content
[0003] Purpose of the utility model: To solve the problems mentioned in the background art, this utility model proposes a drone anti-icing and de-icing system for drone wings and engine lips.
[0004] The technical solution of this utility model:
[0005] A drone anti-icing and de-icing system includes: a left anti-icing and de-icing control box, a right anti-icing and de-icing control box, a left heating component, a right heating component, and a host computer;
[0006] The left and right anti-icing control boxes communicate with the host computer.
[0007] The left anti-icing control box is connected to and powers the left heating component, and the right anti-icing control box is connected to and powers the right heating component.
[0008] Furthermore, the output of the left anti-icing control box is equipped with a left main circuit power supply and a left backup circuit power supply, which are connected to the left heating component.
[0009] Furthermore, the output of the right anti-icing control box is equipped with a right main circuit power supply and a right backup circuit power supply, which are connected to the right heating component.
[0010] Power is supplied through two circuits, primary and backup, providing redundancy and avoiding icing problems caused by a single failure.
[0011] Furthermore, a reverse protection diode is installed between the left main circuit power supply and the left backup circuit power supply, with the cathode of the reverse protection diode connected to the left main circuit power supply; a reverse protection diode is also installed between the right main circuit power supply and the right backup circuit power supply, with the cathode of the reverse protection diode connected to the right main circuit power supply. By setting up the reverse protection diode, the main circuit power supply is used first, and the backup circuit power supply is automatically switched in the event of a main circuit failure.
[0012] Furthermore, the left backup circuit power supply and the right backup circuit power supply are connected via an external interconnect cable. This external interconnect cable enables the left and right anti-icing control boxes to provide redundant power to the left and right heating components.
[0013] Furthermore, the left and right heating components are respectively installed on the left and right wings.
[0014] Beneficial effects
[0015] a) Provides a drone anti-icing system, which improves the safety of drone flight;
[0016] b) The system reliability is improved by using redundant power distribution in key areas;
[0017] c) It has both automatic and manual working modes, which improves the flexibility of the system. Attached Figure Description

[0019] Figure 2 This is a block diagram of the anti-icing and de-icing control box.
[0020] Figure 3 Redundancy distribution schematic diagram. Detailed Implementation
[0021] like Figure 1 As shown, the anti-icing system consists of a left anti-icing control box, a right anti-icing control box, a left heating assembly, and a right heating assembly. The left and right heating assemblies are typically installed on the left and right wings, respectively. The left and right anti-icing control boxes have identical functions: powering the left and right heating assemblies, respectively. Additionally, the left anti-icing control box provides backup power to the right heating assembly, and vice versa. The left and right anti-icing control boxes communicate with a host computer via RS422 communication. The host computer communicates with the UAV ground station via wireless communication, enabling information exchange between the anti-icing system and the ground station. During normal operation, the left anti-icing control box provides heating power to the left heating assembly, and the right anti-icing control box provides heating power to the right heating assembly. If either the left or right anti-icing control box malfunctions, the backup power supply can provide heating power to the malfunctioning heating assembly, ensuring symmetrical operation of the anti-icing system.
[0022] like Figure 2 As shown, the anti-icing control box consists of a power supply circuit, a control circuit, a heating power supply voting circuit, and a power circuit. The number of power circuits, n, is equal to the sum of the number of heating components and the number of heating components requiring backup power. The power supply circuit provides operating power to the control circuit; the control circuit receives communication information from the host computer and generates the anti-icing heating control law; the power circuit receives control from the control circuit, realizing the function of small signal control of high-power lines, and collects the current of each circuit and feeds it back to the control circuit for fault diagnosis.
[0023] like Figure 3 As shown, when the left and right anti-icing control boxes are powered by backup, the backup circuits of the two control boxes can be directly connected by a single cable, and reverse protection is achieved through diodes, which greatly simplifies the form of the backup circuit.
