3.1 Terms and definitions
3.1.1
Unmanned aircraft cloud provider
Operators who establish, maintain and maintain the operation of UAV cloud systems.
4 UAV system and UAV cloud system
The UAV system and the UAV cloud system carry out two-way communication in accordance with the data interface required by this standard. The communication content should include registration information.
Dynamic information, data types, difference data, etc. UAV users can choose to join the UAV cloud system according to their operational needs.
The system can provide navigation services and weather services to UAV users, and conduct real-time monitoring of UAV operating data. The drone system should fly
Line data is reported in time, and the UAV cloud system can trigger functions such as the UAV fence triggering alarm for the added UAV.
5 Requirements for UAV system to transmit data to UAV cloud system
5.1 Basic data requirements
The UAV system should have wired or wireless communication functions, and the transmission data transmission interval should meet the 14.1.2 a in AC-91-FS-2015-31
According to the requirements of b, once the network is interrupted, there is a data temporary storage mechanism, and the data will be resumed immediately after the network is restored, and no one will be recorded in real time
The flight trajectory of the aircraft and the time of record keeping shall meet the requirements of AC-91-FS-2015-31.
5.2 Data format requirements
5.2.1 Registration Information
The registration information is the information that the drone system transmits to the drone cloud system and the drone cloud system is
The code generated by the drone.
Should include at least.
a) Product serial number (MSN). Each drone manufacturer defines the factory number of the drone system, which consists of multiple characters
The product serial number requirements are consistent with those registered in the real-name authentication system;
b) Flight control system serial number (FCSN). The flight control system number defined by each manufacturer and consists of multiple characters;
c) Nationality registration mark or real-name registration number (REG). the registration number is determined by the airworthiness certification department;
d) The number (CPN) generated by the drone cloud operator (hereinafter referred to as the operator) for the drone in the cloud system. consists of multiple characters
Composition, only the first six characters are required, the first three characters of these six characters are the operator code, the fourth to the sixth
