Two-place communication method suitable for South Pole astronomical guarantee platform

Abstract

The invention discloses a two-place communication method suitable for a South Pole astronomical guarantee platform, and the method comprises the steps: enabling the South Pole to locally initiate tasks, and enabling the tasks to run in parallel and to be mutually independent; the South Pole locally classifies various uploaded data, uploading of different types of data is mutually independent, tasks are initiated by adopting respective fixed periods, the maximum execution time of each task is limited, and the maximum flow of each type of data in respective flow period is limited; the method comprises the following steps: actively initiating a control command downloading task locally, resting for a fixed time after downloading all remote control commands, and then actively initiating a next control command downloading task; the specified file uploading and downloading task adopts a communication strategy that the task is initiated in a fixed period and the maximum execution time of each task is limited. According to the invention, two-place communication between the Antarctic local monitoring server and the remote monitoring server of the Antarctic astronomical guarantee platform can be realized, smooth communication between the two places is ensured, necessary information of platform operation is transmitted as timely as possible, and the method is a basis for long-term reliable operation of the platform.

Description

technical field [0001] The invention relates to the technical field of communication in the Antarctic region, in particular to a two-place communication method suitable for an Antarctic astronomical support platform. Background technique [0002] The Antarctic Astronomical Support Platform provides energy, power, communication and data transmission for astronomical observations in Dome A, Antarctica, as well as operational environment assurance for observation equipment. Due to the extremely special and harsh geographical environment of Dome A, the Antarctic astronomical support platform can only be maintained by the Antarctic expedition team for about 20 days each year, and the rest of the time is in a long-term unattended and unmaintained operation state, while the Antarctic astronomical support platform The platform is also the basic support platform for astronomical observation equipment, so its continuous, stable and reliable energy power is the key to ensuring the long...

Problems solved by technology

For the communication between the two places under extreme communication conditions, there are currently two main methods: in the first method, the local autonomously monitors and controls the operating status of the platform, actively sends back alarm information and monitoring data according to certain rules, and receives artificial remote When monitoring the command of the platform, it can reply the command and upload and download the specified file. This method will easily cause the Iridium channel to be blocked when a large number of local alarm messages or the Iridium communication quality is very low, and the artificial remote monitoring platform cannot send Instructions to the Antarctic local platform, which is extremely dangerous, lack the means of remote manual intervention, which greatly increases the risk of platform operation; the second method, the artificial remote monitoring platform actively initiates query data and alarms according to the actual operating conditions Information requirements, high requirements for monitoring personnel, and delayed response

[0004] Due to the particularity of the communication means and maintenance cycle of the Antarctic support platform, the stability and fluency required by it far exceed any other communication scenarios, and the sending data has obvious characteristics of special scenarios. The communication methods used in the existing communication scenarios are all It cannot be applied, and it is urgent to propose a communication method suitable for the Antarctic astronomical support platform
