Technical Field

Background

Currently, there are two implementation ways for unmanned aerial vehicle geofence systems: one is realized by using a product without a high-performance processor (i.e. without advanced functions such as front view obstacle avoidance), and the storage space of a product database without the high-performance processor is very small, so that the method is only suitable for a simple circular flight-limiting area.

Therefore, the data storage device is facilitated to acquire the target flight limiting area data according to the address information of the target data block carried in the first read request by sending the first read request to the data storage device.

In some embodiments, the data processing device and the data storage device each comprise a communication interface to enable communication between the data processing device and the data storage device.

In one embodiment, when the data processing device comprises an enclave processor, the data storage device comprises an application processor, and the enclave processor and the application processor are both located on the same device, the enclave processor and the application processor are connected by a bus.

In one embodiment, when the data processing device is a flight control processor located on the flight device and the data storage device is located on the remote controller, the flight device and the remote controller communicate with each other via a transceiver, data generated by the flight control processor is transmitted to the remote controller via the transceiver of the flight device, and similarly, the data transmitted by the remote controller is received by the transceiver of the flight device and then transmitted to the flight control processor via the bus.

In certain embodiments, the data storage device includes a random read interface for the data storage device to read target flight limit zone data.

In one embodiment, before the data processing device sends the first read request to the data storage device, the address information of the target data block corresponding to the current position information may be determined according to the current position information of the flight device. In some embodiments, the data processing device is installed on a flight device, and the flight device further includes an application processor and various sensors in addition to the flight control processor, and the sensors can acquire the current position information of the flight device and transmit the information to the application processor.

The address mapping table is used for facilitating quick searching of the address information of the target data block.

In an implementation manner, the data processing device may send a second read request to the data storage device, after obtaining the second read request, the second device may respond to the second read request to obtain the address mapping table, and send the obtained address mapping table to the data processing device, and the data processing device receives the address mapping table sent by the data storage device.
