Software Design Of Space Station Integtated Test Channel Equipment Monitoring Terminal System

The channel equipment monitoring terminal is a part of the space station integrated test and control communication ground equipment.TT & C communication system is the only system that maintains the inherent connecti on with the spacecraft platform,it is the necessary guarantee facility.The quality requirements and performance evaluation of measurement and control equipment are essential to ensure the normal operation of measurement and control system.The monitoring terminal mainly completes the management of the equipment and the monitoring function of the general instrument,it can improve the automation management level of the equipment and carry out massive test to guarantee the safety of the monitoring and control task.This thesis makes a detailed analysis on the software functional requirements of monitoring terminal,analyzes the management situation of the channel equipment,put forward the software scheme of monitoring terminal system,clarifies the design requirements of each functional module,using Microsoft Visual C++ as the platform of software development,and gives the software design of the frame structure.The monitoring terminal takes the high-performance server as the core,and implements the local control,remote control and condition monitoring of the equipment through the TCP/IP protocol.First of all,according to the channel equipment management function,familiar with the working principle of link equipment,organize the relevant control instructions according to the user manual of channel equipment such as Cortex and inverter,analyze the key technologies to implement the equipment management function,complete channel device management interface design and functional modules design of link points control,centralized monitoring equipment,network equipment connection status,parameter configuration and operation log etc according to automation,easy operation and modular principle.Secondly,the principle of communication link calculation is introduced.The link test interface is designed according to the calculation method of different link power loss and the test parameter is designed to generate the test report.(SCPI)is used to set the parameters of the spectrum analyzer.The NTGraph control is used to realize the real-time display and playback of the spectrum according to the spectrum storage format.Finally,based on the Gigabit LAN(TT & C network / master control network)test environment composed of channel equipment monitoring ter minal,the control equipment and the master control equipment to debug and analysis the software of space station integrated test channel equipment monitoring terminal system.The software can complete the channel Equipment management,the power loss calculation of the channel link and the monitoring function of the general equipment.After the debugging and analysis,the monitoring terminal software runs stably,and the operation of the software is convenient and flexible.It can realize the automation and network management requirements of the channel equipment.
