Description

Technical Field

[0001] The present invention relates to the field of satellite remote sensing technology, and in particular to a resource management method and device for a remote sensing satellite data real-time processing system. Background Art

[0002] At present, the real-time processing system of remote sensing satellite data processes data quickly while the satellite data is being transmitted downlink, which can meet the user's demand for the timeliness of data products. For example, through real-time and fast processing, data products can be quickly provided to users, or specific payload data of interest to users can be extracted. The non-repeatable nature of satellite data transmission puts higher requirements on the stability and reliability of the real-time processing system, and the reliability of the software and hardware resources that the system operation relies on is one of the important aspects.

[0003] The current resource management mechanism of real-time data processing systems is, on the one hand, to establish a processing resource pool, define the minimum resources required for each execution unit, and impose resource restrictions to provide a basis for resource allocation; on the other hand, it relies on general software and hardware monitoring information provided by software such as Zabbix to determine the availability of device resources.

[0004] The resource management of the remote sensing satellite data real-time processing system requires not only monitoring and alarming the status of the system's general equipment such as servers, storage, switches, etc., but also monitoring the status and fault alarming and processing of special equipment such as demodulators and transmission equipment related to the real-time processing of remote sensing satellite data, as well as special software such as dedicated data acquisition, decompression, and real-time processing. The traditional system resource management method has the following disadvantages:

[0005] (1) Traditional monitoring of the health status of general hardware and software can only monitor the resource usage of the CPU, memory, and network of general equipment, but cannot accurately judge the status of the remote sensing satellite real-time data processing system, and often results in false alarms and missed alarms.

[0006] (2) The real-time processing system for remote sensing satellite data needs to collect, process and transmit satellite raw data in real time. It needs to monitor and manage the status of the demodulator and recorder equipment related to real-time collection, the status of the decompression equipment related to real-time processing, and the status of the transmission system related to real-time transmission. Traditional resource management methods do not monitor and manage the operating status of these special equipment.

[0007] (3) Traditional resource management methods do not integrate the resource management of the remote sensing satellite data real-time processing system with business operations, and do not conduct judgment and analysis on the resource usage of data collection, data transmission, data extraction, and different types of data quick-view processing, and provide accurate business fault diagnosis and resource allocation management capabilities.

[0008] (4) Traditional resource management methods are still at the stage of status monitoring and alarming. They are unable to replace faulty resources and quickly restore data for real-time processing when equipment resources fail. Summary of the invention

[0028] Figure 2 The structure diagram of the resource management device according to the embodiment of the present invention is schematically shown. DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0030] Figure 1 The flowchart of the resource management method according to the embodiment of the present invention is schematically shown.

[0031] Please refer to Figure 1 The specific process of the resource management method of the embodiment of the present invention includes steps S1 to S2.

[0032] In operation step S1, general status information of general devices, special status information of special devices, and operation status information of special applications are obtained respectively.

[0033] In operation step S2, fault information in the general status information, special status information and operating status information is extracted respectively, integrated and fault analysis is performed; based on the fault analysis, it is determined whether the fault information is higher than a threshold, and if it is higher than the threshold, an alarm message is generated.

[0034] In operation step S3, according to the alarm information, automatic online and offline processing is performed on the faulty devices in the general equipment and the special equipment, and data source switching processing is performed on the faulty programs in the special application programs.

[0035] Specifically, the remote sensing satellite data real-time processing system includes multiple general-purpose devices, multiple special-purpose devices, and multiple special-purpose applications. In the above step S1, obtaining the general status information of the general-purpose devices includes: obtaining the hardware status information of various general-purpose servers, storage devices, and switch devices; the hardware status information includes the system status, CPU, memory, and disk space information of the server, the space status information of the storage device, and the inbound and outbound network traffic bandwidth information of the switch device.

[0036] For example, based on the Server-Client mode of the third-party open source Zabbix software, the hardware status information of various general servers, storage devices, and switch devices is obtained in real time through real-time integration and customization through the general SNMP protocol, such as: server system status, CPU, memory, disk space information; storage device space status information; switch device inbound and outbound network traffic bandwidth information, etc. By integrating and processing various types of information, the purpose of obtaining and mastering the overall hardware basic environment information of the system is achieved.

[0037] In this embodiment, in the above step S1, obtaining the dedicated status information of the dedicated device includes: obtaining the rate of the real-time data code stream, the data synchronization lock status, the data continuity, and the data decoding correctness of the baseband demodulator device; obtaining the decompression performance and decompressed output image data of the real-time decompression device; obtaining the network connection data and network link usage data of the real-time transmission device; obtaining the CCD image stitching data, band alignment data, and radiation quality data of the imaging dedicated device.

[0038] Specifically, through the real-time operation results and historical trend records of various data processing services, including the acquired data records, real-time data quality analysis, data decryption and decompression, real-time quick-view processing and display, a comprehensive evaluation and analysis of the operating status of special equipment is carried out.

[0039] For example, the main monitored dedicated devices are as follows:

[0040] (1) Monitoring and management of baseband demodulator equipment. The software is used to monitor and manage the operation of the baseband demodulator equipment in a comprehensive manner, including the rate of the real-time data code stream, data synchronization lock status, data continuity, and data decoding accuracy. On the one hand, an alarm is issued for abnormal data in a single task. On the other hand, the demodulator equipment operation trend management is established through the expert diagnosis system to evaluate and manage the equipment status.

[0041] (2) Monitoring and management of real-time decompression equipment: by monitoring the decompression performance and decompression output image data, the operation of the decompression equipment can be evaluated.

[0042] (3) Monitoring and management of real-time transmission equipment: Through a custom real-time transmission protocol based on TCP / IP, the network connection status and network link usage of the real-time processing system and the real-time transmission equipment are monitored and managed.

[0043] (4) Monitoring of imaging equipment: By checking the output results of the imaging equipment, including checking the correctness of CCD image stitching, checking the accuracy of band registration, and conducting radiation quality evaluation, it is determined whether the imaging function of the imaging equipment is normal.

[0044] Through this embodiment, the real-time data acquisition bit rate and real-time data quality analysis statistics are utilized to perform real-time monitoring and long-term operation trend monitoring of the baseband demodulator equipment operating status, and real-time business monitoring and management of the operating status of special equipment such as decryption and decompression equipment and special imaging equipment.

[0045] In this embodiment, in the above step S1, obtaining the operation status information of the dedicated application includes: obtaining processing information of real-time data collection; obtaining processing information of real-time decryption, decompression and real-time processing of data; and obtaining processing information of real-time data transmission.

[0046] Specifically, by obtaining the progress and status messages sent to the message queue by each business processing program in real time, the current status of each program and system business can be monitored and mastered in real time, and the status information can be formatted and permanently stored in the system database to achieve long-term preservation and post-event tracking of business operation history records, while providing the front-end interface with status information for real-time visual information display. By integrating the progress status information of each business processing program and coordinating with the pre-configured process template information, the task order parsing, sending and real-time scheduling functions are realized for the upstream and downstream processes of business operation, ensuring the long-term and stable operation of each business process in the system.

[0047] For example, the operation status information of the dedicated application for remote sensing satellite data real-time processing system management mainly includes:

[0048] (1) Monitoring of real-time data acquisition services: by monitoring the fluctuation of the code rate of real-time data acquisition, the efficiency of real-time data distribution, and the real-time quality analysis of the original satellite data collected, the purpose of monitoring and managing the operation status of the real-time data acquisition service is achieved.

[0049] (2) Monitoring of real-time data decryption and decompression, and real-time processing services. By monitoring the output data of real-time decryption and decompression, and real-time processing, and evaluating the quality of image data, the operation of related services can be monitored and managed.

[0050] (3) Monitoring of real-time data transmission services: By monitoring the efficiency of real-time data transmission and the efficiency of product distribution, monitoring and management of real-time data transmission services can be achieved.

[0051] In this embodiment, in the above step S2, fault information is extracted from the general status information, special status information and operating status information respectively, and fault analysis is performed, including: based on the fault information extracted from the general status information, special status information and operating status information respectively, an expert library for fault statistical analysis is established, and long-term operation fault analysis of general equipment, special equipment and special applications is performed through the expert library.

[0052] Among them, long-term operation fault analysis of general equipment, special equipment and special applications through the expert database includes: using the correspondence library between fault phenomena and fault causes to analyze and diagnose the fault phenomena, and combining the correspondence information to propose the fault causes of general equipment, special equipment and special applications.

[0053] Among them, according to the fault analysis, it is determined whether the fault information is higher than the threshold. If it is higher than the threshold, alarm information is generated, including: the threshold is the normal working parameter value of general equipment, special equipment and special application programs. When the fault information is higher than the threshold, alarm information is generated and the alarm information is displayed visually.

[0054] Specifically, by integrating the general and special equipment and business processing information obtained by the general equipment monitor, special equipment monitor and business operation monitor, a long-term operation trend statistical analysis of the relevant software and hardware equipment is established to diagnose the overall operation status of the system and provide a processing basis for the fault handling system. After integrating the software and hardware status monitoring information, by combining various threshold waterlines configured in advance, fault alarms are issued for monitoring items that exceed the threshold waterlines, and the alarm information is displayed through the provided visual interface for operators to view and respond in a timely manner.

[0055] Most of the faults in remote sensing satellite real-time processing systems are caused by data transmission errors, special equipment failures, or business software failures. An expert database is established by sorting and analyzing the faults during the long-term operation of the system. The expert database can establish the connection between the fault phenomenon and the cause of the fault. Through comprehensive analysis and diagnosis of various fault phenomena, combined with the information in the expert database, the cause of the fault is given, providing a basis for subsequent fault handling.

[0056] For a specific satellite, the bit rate of input and output data, the bit error rate of data, the efficiency of data dump, and the working bit rate of the dedicated decompression imaging equipment all have normal working ranges. For example, the satellite data downlink bit rate can be used as a standard, with 5% or more as the threshold waterline, to monitor the fluctuation range of data acquisition, data transmission, and data dump bit rates, and to monitor the output efficiency of the dedicated decompression equipment and dedicated imaging equipment to determine the working status of related services; by monitoring the satellite data bit error rate, the working status of the dedicated demodulator equipment is fed back, and combined with the output image status of the dedicated decompression equipment and dedicated imaging equipment, it is determined whether the fault occurs at the front end or the equipment itself.

[0057] In this embodiment, in the above step S3, according to the alarm information, the faulty devices in the general equipment and the special equipment are automatically taken offline and processed, including: according to the alarm information, when the faulty devices in the current general equipment and the special equipment make it impossible to undertake production processing tasks, the faulty devices are taken offline from the resource pool, and the resources are redistributed, and the general equipment and the special equipment are reallocated to perform the business.

[0058] The data source switching process for the faulty program in the dedicated application includes: switching the data source of the original data acquisition channel in the processing information of the real-time data acquisition and the real-time decryption, decompression and real-time processing of the data in the faulty program.

[0059] Specifically, by registering and initializing the hardware equipment resources and software service resource information in the system, the hardware and software in the system are imported, and the imported hardware and software information is installed and deployed according to the actual business needs, forming the association of hardware and software logical attributes, and forming a resource pool architecture for the operation of the system business. On the basis of the resource pool architecture, the support system performs customized resource pre-allocation for the issued processing business according to the actual resource occupation of different businesses, ensuring that various business processing work is carried out under the condition of optimal resources to receive and process the business, and ensuring the reliable and stable operation of business processing.

[0060] For example, the main ways that troubleshooting works are:

[0061] (1) Monitoring and management of hardware equipment. By obtaining the overall system operating status information integrated by the expert database diagnosis, the hardware equipment whose system parameter information exceeds the threshold waterline can be automatically started and stopped based on actual needs, thereby ensuring that the business will not be dispatched to hardware equipment that may have faults.

[0062] For important businesses, the ability of secondary detection and allocation of resources is also provided. Before the start of important business, the fault handling system will re-acquire the overall operating status information of the system. If the pre-allocated resources of the business have a fault and are offline, the resources will be secondary allocated to the business and rescheduled to work on normal nodes to ensure the normal execution of the business.

[0063] Specifically, based on the cause of the failure, determine if the current device or software is unable to undertake production processing tasks, take the failed device offline from the resource pool, and take the business capabilities corresponding to the failed software offline.

[0064] In data processing, in order to ensure the efficiency of processing, we use resource pools and pre-allocate resources. For important services, we re-confirm the equipment status before the service execution time. If the equipment to be responsible for the service is found to have a fault and is offline for processing, the service execution equipment will be reallocated.

[0065] (2) Monitoring and management of software services. During the operation of the services, combined with the results of real-time data quality analysis and real-time data processing, the operational failures of real-time processing services can be diagnosed and processed. For example, in the event of a failure, the data source of the original data collection channel of the original data real-time collection and transmission services can be switched. When a real-time data processing device fails, the processing device can be replaced and the context environment can be migrated.

[0066] Specifically, in the event of a failure, the data source of the original data collection channel can be switched to the backup channel for the original data real-time collection and transmission business to ensure real-time transmission of the original data; when a failure occurs in the real-time data processing equipment, the context environment such as the production progress, input and output information, and dependency information of important production businesses can be automatically migrated to normal equipment, avoiding the need for manual intervention to troubleshoot and restart the business.

[0067] Through the embodiments of the present disclosure, based on the collected monitoring information of general and special equipment and business software, an expert database is established for diagnosis, and automatic online and offline equipment and operation status alarm management are performed; the resource occupancy of real-time data collection, data transmission, data extraction, and real-time processing of different types of data are classified and monitored; faulty equipment in real-time data processing services is quickly replaced to ensure the stable operation of real-time data collection and transmission and real-time processing services.
