Design And Implementation Of The Upper Computer System Of Detector Life Test Based On QT

The detector module is the photoelectric signal conversion component in the core of space remote sensing detection,which is used to obtain abundant remote sensing data information.For a field like space,once a probe is put into use,it's very difficult to re-operate the equipment.The service life of the detector is the key technical index of its reliability,and life test is an important link to evaluate and analyze the reliability of the detector.The design and development of the control software of the upper computer is very important for the development of life experiment and the acquisition of effective data.In this paper,the upper computer software is designed to complete the analysis of the life test of the detector by collecting,processing,displaying and storing the relevant data of the detection equipment.In this paper,the software design of detector life test based on Qt is studied.Firstly,combined with the on-orbit working mode and time requirements of the detector,the life test process of the detector was determined.Based on this,the software development requirements were analyzed in detail.On this basis,the overall structure of the software system was divided.The communication module is designed for information exchange,the command control module is designed to guarantee the stability of the system,the counting module is designed to guarantee the reliability of the system,the communication data visualization module is designed to display the data,and the database module is designed to store the test data.Then,the human-computer interaction interface is realized,and the selection and construction of interface controls of each module of the system are described in detail.The logic functions of each module are realized by using serial port technology,database technology,QCustom Plot plotting tool,and Qt's unique designer interface and signal and slot mechanism.Finally,based on the completion of software design and development,a number of tests have been carried out,such as communication connection,command control and counting function.The test results show that each module has good function and the software system has high practicability,which can effectively save labor and time costs.It plays a positive role in promoting the development of the detector life test and the evaluation of the detector life.The software system can meet the development needs.
