Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0036] Usually, the real-time data downloaded by the probe carried on the lunar satellite mainly includes the engineering data, telemetry data and scientific data of the payload.

[0037] Engineering data refers to the working state parameters collected by the detector when the lunar satellite is in orbit. The engineering data shows the calibration of each frequency channel of the detector, the hardware working mode and software running status of the observation branch, etc. To fully reflect the working status of the detector. The display mode of project data can be two forms of numerical list and graph. When the numerical list is displayed, the data value of the project source package is displayed. When displayed graphi...

Abstract

The invention discloses a method for processing the real-time data of a solar wind low-energy ion detector for a lunar satellite. The method comprises the following steps of: initial data reception, in which initial data downloaded by the solar wind low-energy ion detector for the lunar satellite is received in real time; framing data processing, in which the downloaded initial data is subjected to frame synchronization, descrambling and Reed-Solomon (RS) decoding to obtain framing data; channel processing, in which the framing data is subjected to branching de-framing and sub-packaging to obtain a data source packet of the solar wind low-energy ion detector; data block extraction, in which the data source packet of the solar wind low-energy ion detector is unpackaged to generate a data block of the solar wind low-energy ion detector; physical quantity conversion, in which the generated data block of the solar wind low-energy ion detector is converted into the data of the solar wind low-energy ion detector having an actual physical meaning; and client displaying, in which the converted data of the solar wind low-energy ion detector is sent to a client for real-time displaying. According to the method provided by the invention, the real-time data of the solar wind low-energy ion detector for the lunar satellite can be processed and monitored totally and correctly in real time, so that a working state and a detection result of the low-energy ion detector are monitored and displayed effectively, and a load state is controlled and adjusted in real time according to a monitoring result.

Description

technical field [0001] The invention relates to a method for processing real-time data of a lunar satellite solar wind low-energy ion detector, which is used for realizing real-time processing and quick viewing of the real-time data of the lunar satellite solar wind low-energy ion detector. Background technique [0002] The lunar exploration project is a systematic project for exploring the environment and resources of the moon. The lunar exploration engineering system mainly includes satellites, rockets, launch sites, measurement and control, and ground application systems. The ground application system mainly includes data receiving subsystems (ground stations), operation management subsystems (OMS), etc. The ground station receives and stores the downlink detection data in real time according to the business operation plan, and sends the received data to the operation management subsystem in real time. The operation management subsystem is responsible for formulating the...
