In recent years, the field of consumer drones has developed rapidly, and drones have been seen everywhere in life and entertainment. And the industrial drone market with richer and larger usage scenarios has risen.
Perhaps the first scene of many people's use of drones is still aerial photography. But now, in agriculture, plant protection and animal protection, disaster relief, surveying and mapping, power inspection, disaster relief and so on. In some scenes where people cannot safely approach, drones have unique advantages and are a good supplement to ground transportation in special environments.
UAV is a self-powered and controllable unmanned aerial vehicle. The entire UAV system mainly includes the aircraft body, flight control system, data link system, launch and recovery system, power supply system and other parts. Thanks to this highly coordinated and complex system, drones can fly stably and safely. And can perform tasks such as load bearing, voyage, information collection, and data transmission.
Compared with consumer drones, the most important thing about industrial drones is the adaptability of the aircraft industry. In actual application, the specific conditions of each industry will cause the emphasis on certain characteristics of drones. For example, forest fire-fighting drones require lines to be flame-resistant, while ocean border patrols require lines to be resistant to salt and alkali.
But consumer drones will pay more attention to their ease of use, universality and cost. Therefore, the quality, function, and environmental resistance requirements of industrial-grade UAVs will be higher.
For connectors, drones mainly use two types: signal connectors and power connectors. As an industrial-grade UAV as a special application environment, its connector must also use industrial-grade. At the same time, the special state of flight needs to be considered.
A safe and reliable connector is one of the keys to the normal flight of the UAV. In general, it includes five major needs:
1. Small size and light weight:
For drones that require low power consumption and high endurance, each gram of weight gain means a reduction in flight distance or an increase in energy demand. Lightweight connectors can effectively reduce their own weight.
2. Strong anti-vibration:
When the drone is in a steady flight state, there will be a continuous state of high frequency and low amplitude. In the event of sudden climb, descent, wind, etc., the entire fuselage will be violently bumped. Therefore, the connector must have a certain degree of vibration resistance.
3. Strong waterproof and anti-corrosion ability:
At high altitudes, water vapor is easily affected by low temperatures and easily condenses into water mist or ice crystals. When it comes to bad weather such as rain and fog, the requirements for waterproof performance will be further improved. In addition, agriculture, plant protection and other industries will have actions such as spreading fertilizer and pesticides, and there are certain requirements for the corrosion resistance of the connector.
4. Powerful signal transmission capability:
There are various sensors on the drone body. The connector shielding and anti-interference structure design can effectively avoid external electromagnetic interference, and ensure that the collected signals are transmitted to the body PLC in real time at high speed, stability, and without delay;
5. Large power transmission capacity:
The current transmission capacity of the connector is related to the thickness of the pin, and also related to the material of the pin. Choosing a connector with more conductivity and better performance can ensure that the body battery provides continuous and stable power to the motor.
