Tethered UAV System

Hardware and function part:

The main contents are as follows: 

1. The strong and weak electricity are separated. At present, the high voltage on the ground of the product (400 to 500V) has a switch for isolation, which can protect the operator from the danger of high voltage electric shock when taking in and unwinding the cable. 

Insurance (many manufacturers output high voltage 400V~800V when they turn on the cable). 

2. The cable can realize automatic take-off and take-off, and the pulling force and speed can be adjusted to match the aircraft with different take-off weight, the accuracy of take-off and take-off can be achieved. 

3. The starting voltage of the ground power supply can be adjusted in the range of 380-400V, and the high-voltage compensation voltage can be adjusted in the range of 400-450V, which can be adjusted according to the set voltage range. 

Dynamically compensate the voltage of the heavy load to enhance the load capacity of the aircraft, which can reach the parameter of 100m load 10kg at present. 

4. The product can be dragged and transported by one person, and the outer box can be waterproof, salt fog, wet and so on. The whole package has no outer hole, which can effectively protect the product. 

5. All the structural strength of the product is purchased according to the structural standard of military industry, which can be used in the environment of strong vibration.


Software and function part:

1. Self-test function: it can judge the connection status of each module and locate the problem in time. 

2. Judgment function: after the equipment starts, it can judge whether the winch winding position is normal or not, so as to avoid the danger caused by the sudden quick winding clamp to the finger when the winch is arbitrarily adjusted (the winch torque can reach 150kg tension). 

3. Alarm function: the system can accurately record the wire length, output voltage, output power and real-time temperature acquisition. If the set value is exceeded, it will be prompted automatically. 

Alarm; when the winch is not returned to 0 in the start-up stage when in use, in order to reduce personnel's hand injury, the system will automatically alarm and the aircraft can not pull the cable; cable.

Pulling out 90m and 95m will give an automatic alarm to prevent the aircraft from breaking over the length of the cable. 

Alarm when the cable is disconnected, and the work can be resumed directly after the connection is continued. 

4. Cable length display function, which can be accurate to 0.1m (can be raised to 0.01m). 

5. The secondary parameters of the system are shown in turn, including current voltage, power, current, working temperature of box and winch. 

6. voltage automatic follow function, ensure that the far-end voltage does not change, automatic compensation, functional peripherals, users can manually adjust the voltage according to the actual load
