Problems solved by technology

[0005] The traditional information communication method is to cover the data communication range of each member node forming a distributed cluster to the entire cluster, then two member nodes can communicate directly, and then the member aircraft with the space and ground measurement and control function receives the ground telemetry informat

Example Embodiment

[0025] The present invention will be described in detail below with reference to the drawings and embodiments.

[0026] Establish a distributed cluster aircraft system, the system includes N member nodes, the maximum transmission power of each member node is P, that is, the transmission power of the member nodes is adjustable between 0 and P, and the N member nodes in the system It includes member nodes with world-wide measurement and control functions. The distributed cluster aircraft system established in this embodiment is such as figure 1 As shown, the system has 5 nodes A(-4,0,0), B(0,0,0), C(3,-3,1), D(4,-1,1), E( 4,1,3).

[0027] The first step is to make the i-th member node broadcast a handshake message with maximum power, and the handshake message contains its own coordinates (x i , Y i ,z i ) And the ID that identifies its own identity information i , Where 1≤i≤N.

[0028] Step 2: All member nodes in the distributed cluster aircraft system except the i-th member node rec...

Abstract

The invention discloses a telemetry and telecontrol method of distributed cluster aircraft system and belongs to the technical field of distributed cluster aircraft telemetry. The method comprises the steps that each member node broadcasts handshake information and receives coordinate information transmitted back by other nodes, according to the coordinate information, relative distance between every two member nodes is computed, information transmission is carried out between each member node and another member node which is closest to the member node in relative distance, and accordingly a communication link between every two member nodes is established, the hop number of each communication link is recorded; a member node which has a space-ground measurement and control function is used as zero-link node, other member nodes are distributed into different rings according to the hop numbers of the communication links between the member nodes and the zero-link node, during telemetry, telemetry information is transmitted from the outermost link to inner links in sequence according to the established communication links, and during telecontrol, telecontrol instructions are transmitted from the zero link to outer links in sequence according to the established communication links. The telemetry and telecontrol method achieves energy management of a telemetry and telecontrol process.

Description

technical field [0001] The invention belongs to the technical field of remote measurement of distributed cluster aircraft, and in particular relates to a remote measurement method of cluster aircraft. Background technique [0002] At present, with the expansion of the application of spacecraft systems and the continuous advancement of aerospace technology, it is required that the spacecraft should have certain flexibility and anti-risk capabilities. The distributed cluster aircraft can complete the space launch mission through batch launch, on-orbit assembly, and cooperative operation, which can better solve the on-orbit upgrade, maintenance and replacement, and meet the needs of flexibility and reliability. [0003] The distributed cluster aircraft system is composed of multiple members running in different orbits. The members communicate with each other through various data information. The system can communicate the load data and operation control data through the load ne...
