What checks do you need to do after the UAV test flight?

When the UAV is produced, these test links are needed to ensure the reliability of the hardware.

1. High and low temperature test. Because the operating environment of unmanned aerial vehicles (UAVs) is often changeable and complicated, each UAV has different control capabilities for internal power consumption and heat generation, and its own hardware has different adaptability to temperature, so in order to meet the operational requirements under more or specific conditions, it is necessary to carry out flight tests at high and low temperatures. It can't be said that there is no problem for the plane to fly in the south, but it can't take off when it is taken to the north, or the drone is stored at high temperature or low temperature, and the plane has an unknown fault. For ordinary consumers, this result is unacceptable.

2. Drop test. Drop test is a routine test for most products at present. On the one hand, it is to test whether the packaging of UAV products can protect the product itself well and ensure transportation safety; On the other hand, it is actually the hardware reliability of the aircraft. After all, planes, like commonly used smart phones, will inevitably have some bumps or even accidental crashes. Good and reliable hardware performance can greatly enhance the aircraft's resistance to the outside world, minimize machine damage, and reduce maintenance time and cost.

3.GPS star search test. For UAV, GPS module is a very basic hardware requirement and belongs to one of the important sensor units of aircraft control system. It can not only provide data information such as position coordinates and flight speed, but also help realize many intelligent functions such as precise hovering, route planning and automatic return. Therefore, the speed and quantity of aircraft searching for stars are very important for drones. The speed is too slow, and it may take a long time to take off. The number of stars is too small or unstable, and the loss of stars during flight will actually affect flight control and safety.

4. Vibration test. There are many sensors inside the UAV, such as IMU inertial measurement unit. If these sensed data are affected by vibration, the final result is that the drone may be "crazy" and completely out of control. Secondly, the internal hardware structure is complex, which requires high integration strength of the fuselage. If vibration causes abnormal hardware connection, loose screws or modules, etc. In fact, it is intolerable. At the same time, the vibration of the aircraft itself will affect the stability of flight and the effect of aerial photography. You know, if you go out often, the road surface will be affected by the bumps and vibrations of the vehicles, and the take-off and landing will also be affected by the vibrations, so the resistance of the aircraft to the vibrations can not be ignored.

5. Key tests. The remote controller of the drone has a control rocker and many function buttons, and the fuselage also has frequency buttons and battery buttons. These keys will age and wear with long-term frequent use. The key test is actually to test whether these keys can continue to work normally and how strong their anti-aging ability is. After all, if the button is broken, flight control and function use will be affected, and the customer experience will be poor.

6. Line bending test. With the development of UAV integration, many connections are reduced by shopping malls, but there will inevitably be some connections between modules, and these lines will be bent for a long time. Therefore, it is very important to test the connection reliability between modules through necessary bending tests. For example, PTZ is generally under the fuselage, and the FPC cable of PTZ is visible to the naked eye. If the cable is damaged, PTZ will be disconnected from the fuselage and will not work. Also, once these cables are damaged or short-circuited, it will not affect the normal work of other modules of the UAV.
