Description
Technical Field
The invention relates to a monitoring management system, in particular to a distributed monitoring management system and a distributed monitoring management method for a remote sensing satellite ground station.
Background
The ground system of the remote sensing satellite is one of five major systems of satellite, carrying, transmitting, measuring and controlling and ground application in satellite engineering, and the ground station of the remote sensing satellite is an important component of the ground system of the remote sensing satellite and is mainly responsible for receiving, processing and distributing the data acquired by the load on the satellite. With the development of the aerospace industry and the popularization of the application of satellite remote sensing data in China, the number of in-orbit remote sensing satellites is increasing day by day, the situation that a plurality of satellites transit at the same time is more and more frequent, and higher requirements are put forward on the data receiving capacity of the ground station of the remote sensing satellite. In order to improve the capability of a ground station to receive multiple satellite data simultaneously, more receiving antennas and channel devices need to be built on the ground station, so that the number of the ground station devices is rapidly increased, and the devices comprise antennas, frequency converters, demodulators, recording quick-view devices and the like. Therefore, two problems are brought to the ground station monitoring and management system, and firstly, along with the increase of the number of the devices, how to ensure that the ground station monitoring and management system can reliably operate; secondly, the ground station monitoring and management system needs to flexibly adapt to the continuously expanding requirements of the ground station, and newly added equipment is quickly integrated into the existing monitoring system under the condition that the daily task operation is not influenced.
The service operation management system (i.e. service operation management unit) is an organization and management center for remote sensing satellite ground station service operation, and different remote sensing satellite ground systems are different in service and function settings, and the service operation management systems are also different in design. The service operation management function unit is different in the existence form and the structural division of each ground station, or exists as an independent system or is combined into other systems. The monitoring management system is an operation control center of a remote sensing satellite ground station and is responsible for monitoring the operation states of all equipment in the whole station, controlling equipment parameters and organizing each equipment to complete a data receiving task of a transit satellite.
The remote sensing satellite data receiving task has the characteristic of time non-reversibility, and once the ground station has operation failure, the data downloaded by the satellite cannot be received, so that the serious result of data loss can be caused. Therefore, the remote sensing satellite ground station has higher requirements on the reliability of the system, and the monitoring management system is an important guarantee for the safe and reliable operation of various services of the ground station.
The existing remote sensing satellite data ground station monitoring and management system mainly adopts a C/S framework and a centralized monitoring mode. The ground station monitoring and management system is composed of server software and client software, wherein the server software is mainly responsible for completing communication processing with all devices of the ground station, completing scheduling of various receiving tasks and organizing daily service operation of the ground station. The client software mainly provides a human-computer interaction interface, and the client acquires and displays detailed state parameters of the equipment through communication with the server software; and monitoring the typical working state of each device in real time in the data receiving process, and performing manual intervention if necessary.
The existing monitoring management system mainly has the following defects that: the monitoring management of all the devices of the ground station is centralized in a server process, with the increase of the number of antennas of the ground station, the load and complexity of the server software of the monitoring management system are obviously increased, and the monitoring management system also needs to complete auxiliary functions of system calibration, testing, data acquisition, information management and the like. Various auxiliary functions, a monitoring function, a task flow automatic control function and the like are centralized in the same process for processing, and the abnormity of the auxiliary functions can cause the integral breakdown of the system and influence the operation of the core function of the system. In addition, for the multi-antenna remote sensing satellite ground station, the data receiving tasks of all antennas of the station can be influenced by the functional failure of the software of the server side of the monitoring management system. In addition, the construction of the satellite ground station is gradually promoted, and when the ground station expands the capacity, hardware devices such as a new antenna, a field amplifier, a frequency converter, a demodulator and the like need to be added. Under the existing monitoring system architecture, when a hardware device is newly added, a monitoring management system of a ground station needs to be modified and upgraded, monitoring processing on the newly added device is added in original software, and control on a task flow of a newly added antenna is added. After the software transformation is completed, the task of the ground station is stopped to complete the switching of new and old software, and the requirement of 7 × 24 hours uninterrupted operation of the ground station cannot be met.
