To analyze the universal testing system plays an important role in the process of space experiment facilities being developed. A design method of universal testing system for a variety of microgravity science experiment facilities is proposed. By analysis of the characteristics of the payloads, the objects of control are classified, and different operations are used for different control object. The process of the experiments is decomposed as a series of operations on specific time. By configuring the static configuration form, action configuration form and dynamic configuration form, the control of the process of experiments is achieved. The testing system is composed of a computer, a power supply and an RS422 communication interface. For different payloads, the power cable and communication interfaces are uniform, to ensure the testing system is universal. The universal testing equipment serves the development of the experimental facilities. These experiments include: space experiment of evaporation and fluid interfacial effects; study on ignition, soot emission and smoke distribution of wire insulations by overload; investigation of the coal combustion and pollutant formation characteristics under microgravity; study on the colloidal assembling; solidification and crystal growth in space; roles of space radiation on genomic DNA and its genetic effects; potential and molecular mechanism of osteogenic differentiation from human bone mesenchymal stem cells. The universal testing equipment plays a very important role in determining the experimental parameters, the space experimental process, the facility specifications testing, the environmental test, the EMC test, and the facility acceptance check process, etc. |
