Description

IoT-based satellite ground communication monitoring and control system

The present invention relates to a satellite ground communication monitoring and control system, and more specifically, to remotely monitor and control various satellite ground communication equipment of a satellite ground communication system, including a satellite earth station, and to deliver failure reports about equipment errors to the operator in real time. It is about an IoT-based satellite terrestrial communication monitoring and control software system that can output reports on status and failure information and deliver equipment operation information and failure information by linking with an IoT message server.

In the field of satellite information and communication, advanced communication countries, including Korea, have developed wireless communication systems using satellites. In Korea, since 1995, full-fledged satellite terrestrial communication system research and development has been carried out by telecommunication companies, satellite terrestrial communication equipment manufacturers, and national research institutes by element, from hardware including satellite terrestrial communication terminals to software including satellite control systems and earth station monitoring and control systems. It has been centered around. The satellite ground communication surveillance and control system is a system for professionally managing communication equipment for satellite ground communication, ranging from a satellite control system for operating satellites and a satellite ground communication earth station that provides communication services to mobile small satellite communication systems and vehicle-type communication systems. It is a basic system that must be operated including the satellite terrestrial communication system. The system that manages the satellite terrestrial communication system mainly includes a control system, mission management system, and network management system, and the monitoring and control system and TT&C system are operated as the base systems. Among these, the monitoring and control system is a low-level basic system and is an essential system. Depending on the equipment configuration and scope of service in the satellite terrestrial communication service system, it is a small monitoring and control system for managing VSAT (Very Small Aperture Terminal), a small satellite terrestrial communication system. Solutions are being developed, applied, and operated depending on the operational category, ranging from systems to large-scale integrated systems for managing satellite earth stations (ES). Currently, the field of satellite terrestrial communication monitoring and control system software, which plays a monitoring and control role as a base system in these various categories, is currently being developed by world-class satellite terrestrial communication monitoring and control system companies that apply artificial intelligence functions using big data analysis techniques and machine learning techniques for diagnosis. This is the market situation where products that provide system equipment failure diagnosis and prediction functions are being released.

However, the market situation is such that professional solutions are not known in most countries, except for some advanced satellite communication countries with a long history of satellite terrestrial communication services such as the United States, Germany, Canada, and France, and in general, satellite terrestrial communication systems are operated in Korea. The main body handles monitoring and control tasks by operating exclusive imported software provided by overseas satellite terrestrial communication equipment manufacturers or proprietary software developed in-house.

Additionally, the satellite terrestrial communication system can be operated as a national important infrastructure facility depending on its size. At this time, performance degradation or breakdown occurs in the satellite ground communication system service, which can include military tactical satellite communication terminals, which are major national defense tactical software assets, and broadcasting such as civilian video relay, and operators and managers are unable to operate appropriately. This may cause difficulties.

However, the dedicated software of the equipment manufacturer used when remotely managing the current satellite ground communication equipment for operation and maintenance, or the dedicated software developed in-house by the operating entity that operates the satellite ground communication system, only provides basic operating commands. In most cases, other advanced settings of the equipment are not supported and are limited. In addition, in this case, due to the nature of the operation of satellite terrestrial communication equipment, cross-reference operation and cross-reference testing within the system related to switching and up-down link are essential, and for this, it is integrated and remotely connected to the equipment. Therefore, there are limits to efficient operation that supports overall advanced parameter settings. In addition, for the monitoring and control of the satellite ground communication system, the dedicated software of the equipment manufacturer or the software produced independently by the operating entity that operates the satellite ground communication system may be used to determine the equipment communication configuration and It can be difficult to keep your equipment management screens consistent and consistent. In other words, if the integrity of the communication connection configuration and equipment management configuration for satellite terrestrial communication equipment is not continuously guaranteed to operators and managers, operators and managers will not be able to solve equipment operation problems or support efficient monitoring and control. Private telecommunication companies will experience immediate service loss, and if the subject of satellite terrestrial communication service is an organization such as a government research institute or the military, the loss can be very serious.

In addition, there are cases where it is essential to transmit major information about failures or operational status occurring in satellite terrestrial communication equipment to external equipment such as a satellite terrestrial communication network management system in the form of professional messages, and also to use big data analysis and artificial intelligence functions. The number of cases requiring technological application is also increasing.

Therefore, research is needed to support the operational integrity of satellite terrestrial communication remote monitoring and control system technology, which is essential in the operation of satellite terrestrial communication systems, and interoperability with big data analysis and artificial intelligence function support systems for satellite terrestrial communication monitoring and control systems is needed. Research on existing IoT messaging technologies is needed.
