Embodiment Construction

[0036] The system block diagram of the present invention is as figure 1 shown. figure 1 Among them, the lower computer 1 to the lower computer N are the sub-system devices (bus communication slave nodes) connected to the platform bus, and the lower computer M to the lower computer M+N are the sub-system devices connected to the load bus ( bus communication slave nodes), these slaves generate telemetry parameters. figure 1 Among them, the bus communication master node is the master node of the platform bus and load bus, responsible for scheduling and managing the platform bus and load bus, polling the telemetry data of each bus communication slave node, and sending instructions or data blocks to each bus communication Execute from the node. figure 1 The central data transmission system is mainly responsible for establishing a high-speed data downlink link from the satellite to the ground, and sending the data stored in the bus monitoring module to the ground as required.

Abstract

The invention discloses a satellite fault rapid positioning system based on bus monitoring; a bus communication main node is responsible for polling telemetry data, distributing, and broadcasting data scheduling transmission to a bus communication slave node and a bus monitoring module on the bus; the bus communication slave node is responsible for acquiring the telemetry data of the system, and polling, receiving and broadcasting the data in response to the telemetry data of the bus communication main node; the bus monitoring module is mainly responsible for receiving, formatting and storingall communication data on the bus; an order sent from the ground is transferred to the bus monitoring module through a ground order control; the bus monitoring data at an appointed position is sequentially sent to a data transmission system according to the content of the order by the bus monitoring module, and then transmitted to the ground by the data transmission system; or the bus monitoring data polling at the appointed position is performed on the bus through the ground order control, the bus monitoring data is packed and processed to form the satellite telemetry data packet to be sent to a responder which is used for transmitting the satellite telemetry data packet to the ground; and the ground device performs the fault positioning or extracts the concerned satellite telemetry dataaccording to the received bus monitoring data.

Description

technical field [0001] The invention relates to a satellite fault fast positioning system, which is suitable for satellite fault positioning in the satellite AIT stage and in-orbit operation stage. Background technique [0002] At present, satellite telemetry data is the only basis for fault location in satellite AIT phase and in-orbit operation phase. Commonly used satellite telemetry data is generated by the main node of the bus communication and the telemetry parameters of each subsystem are collected through the on-board bus, packaged and processed, and then downloaded via the on-board transponder. Telemetry data is the only way for the ground to understand the working status and health status of the satellite. [0003] Due to the complexity of the satellite system, when a satellite fails, the original data used to locate the fault is extremely important. Often after a fault occurs, due to the lack of relevant direct telemetry evidence, it takes a long time to locate a...
