1. High and low temperature test. Because the environmental conditions of unmanned operation are often varied and complicated, and each machine has different control ability for internal power consumption, the hardware of the aircraft itself can adapt to temperature, so in order to meet more For many or specific job requirements, flight testing at high and low temperatures is a must. It can't be said that there is no problem in flying the aircraft in the south, but it is impossible to take off in the north, or the drone is stored under high temperature or low temperature conditions, the aircraft has an unknown fault, etc., for ordinary consumers. Said that such results are unacceptable.
2. Drop test. The drop test is a routine test that most products need to do at present. On the one hand, it is to test whether the packaging of the drone product can protect the product itself to ensure the safety of transportation; on the other hand, it is the hardware of the aircraft. Reliability, after all, the aircraft is like a common smartphone, inevitably there will be some small bumps or even accidental crashes. Good and reliable hardware performance can greatly enhance the aircraft's ability to resist the outside world. Damage is minimized, reducing maintenance time and costs.
3. GPS search star test. For a UAV aircraft, the GPS module is a very basic hardware requirement and is one of the important Sensor units of the aircraft control system. Not only can it provide data information such as position coordinates and flight speed, but also can assist in many intelligent functions such as precise hovering, route planning and automatic returning. Therefore, the speed and number of aircraft search stars are very important for drones. The speed is too slow. You may have to wait a long time to take off, the number of stars is too little or unstable, and you lose during the flight. Stars also affect flight control and safety.
4. Vibration test. There are many sensors inside the drone, such as the IMU inertial measurement unit. If the perceived data is affected by the vibration, the final result is that the aircraft may be “mad†and completely uncontrolled. Secondly, the internal hardware structure is complex. The integration strength of the body is relatively high. If the vibration causes the hardware connection to be abnormal, the screw or the module is slack, etc., it is actually not tolerable. At the same time, the vibration of the aircraft itself will affect the stability of the flight and the effect of aerial photography. You should know that if you go out often, the road will be affected by the bumps and vibrations of the vehicle. The takeoff and landing are not smooth or the bumps are often affected by the vibration, so the aircraft's ability to resist vibration can not be ignored.
5. Button test. There are control sticks and many function buttons on the remote control of the drone. There are also frequency buttons, battery buttons, etc. on the body. These buttons will age and wear with long-term frequent use. The button test is actually at the maximum. Under the intensity of use, test whether these buttons can continue to work normally, and how strong the anti-aging ability is. After all, the buttons are broken, the flight control and function use will be affected, and the customer experience is not good.
6. Line bending test. With the development of the integration of drones, many of the connections have been reduced by the mall as much as possible, but there will inevitably be some connections between modules, and these lines will have long-term bends. Fold, so the necessary bending test to check the reliability of the connection between the modules is very important. For example, the pan/tilt is generally below the fuselage. The FPC cable of the pan/tilt can be seen by the naked eye. If the cable is damaged, the pan/tilt will be damaged. It is disconnected from the fuselage and cannot work. Also, if these cables are damaged or short-circuited, it will not affect the normal operation of other modules of the drone.
Gear sensor has been widely used in the automotive and industrial field, which is important to the measurement of velocity, angel, angular velocity, direction of rotation.
