Redundancy and European Law
We at Direct-Drone.com only sell the best equipment in the world.
In some countries drones are allowed only with redundant configuration, like in the case of Austria, European Union.
Redundancy means that important components have to be replaced and the Drone should not crash in case of failure of a (single) component (eg, motor, receiver, Flight Control, etc.).
Until now, you could build the copter only with redundant drives and power supply.
In (total) loss of Flight Control or the I2C bus it would nevertheless still crash.
We comercialize Drones that now have a redundant concept developed and tested, which also allows a configuration with redundant FC and data to the BL controllers.
Principle of operation:
- A second FC is connected 'from behind' to the serial port of the BL V3 knob.
- The new bus is decoupled to each controller via resistor or diode, so that a single regulator that bus can not be paralyzed.
- In flight the backup FC sends data continuously to the BL-Ctrl
- Report The BL-controller to the main FC that they get additional data. In HoTT display which is then displayed.
- If the brushless controllers have a fault on the I2C bus, or get any data from the main FC, they immediately turn to the data of the second FC
- The switch works so smoothly that the MK is not to waver
- This also works when the main FC will make a reset in flight
- Basically, you can equip the second FC with NC and GPS
To test (or feature) you can per preset the I2C bus with a switch off and on, and thus switch to the redundant FC.
Because in the demonstration is not drastic enough, however, I have drawn as hardness test using a servo connector to the FC.
