MH/T 2009-2017Interface specifications of unmanned aircraft and cloud system (English PDF)

3.1 Terms and definitions

3.1.1

Unmanned aircraft cloud provider Operators who establish, maintain and maintain the operation of UAV cloud systems.

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 the characters represent the category of the drone. The fourth character represents the category in the UAV operation management classification, namely I~VII, which the corresponding relationship is shown in Table 1; the fifth character corresponds to the category corresponding to the drone, see Table 2 for details, and the sixth character is a reserved bit.

5.2.3 Data type description

5.2.3.1 The data type description of UAV cloud system is shown in Table 4.

5.2.3.2 See Table 5 for the description of UAV cloud system data information types.

5.3 Difference data

In order to improve the efficiency of data transmission, when the amount of transmitted data is large, in the case of meeting the data update rate requirements, according to the update time the unit only provides data items that are different from the previous data package. According to the characteristics of dynamic information and static information, the difference data only includes but not complete all include the content in the dynamic information (see Table 3) in the interface transmission data.

9.1 Basic requirements

9.1.1 The data provided by the UAV system to the UAV cloud system includes the data items required in 5.1 and 5.2.

9.1.2 The data provided by the UAV cloud system to the UAV system should include the command data items required in Chapter 6.

9.1.3 The test should be conducted in an environment that satisfies the operation and communication of the UAV system and UAV cloud system.

9.2 UAV cloud system interface level

9.2.1 The UAV system and UAV cloud system interfaces that meet the requirements of Chapter 5 of this standard are Class A.

9.2.2 The interface of UAV system and UAV cloud system that meets the requirements of Chapter 5 and Chapter 6 of this standard is Class B.

9.3 Data communication performance requirements

9.3.1 In the data link between the UAV system and the cloud system, it should be confirmed that the Class A interface can correctly transmit the real-time update of the data.

Related requirements in AC-91-FS-2015-31.

9.3.2 In the data link between the UAV system and the cloud system, the level B interface shall be met. In addition to meeting 9.3.1, the UAV cloud system shall also be confirmed the correctness of the data transmitted by the system to the UAV system.
