Background. The relevance of this topic is confirmed by the high requirements to reliability requirements to a liquid-propellant rocket engines. Main design goal of the system is the number of tasks: increasing the range of sensors and list their measured parameters, cost reduction and mass-dimensional parameters of the system, increasing the area and number of monitored objects, the automation of procedures for the accumulation, systematization and classification of statistical data of fire tests components and assemblies of the engine.
Materials and methods. Peculiarities of construction of measuring and monitoring systems. Showing circuit solutions, and describes the principles of operation of the system. The algorithm of information interaction of data acquisition unit and digital sensors.
Results. Designed project of the system of measurement, monitoring, control and diagnostics of the engine at fire test bench consists of a distributed network of sensors of physical quantities (DFV), which measure the physical parameters of the engine, and block data collection, providing connection DFV, continuous or systematic collection and processing of the signals transmitted by measuring channels with sensors and transmitting the processed signals through the channel «Ethernet» connection to the higher level system.
Conclusions. According to the research results a comparison of the developed system used for the same purposes at the present time and concludes that there is significant superiority of the first that should ensure higher reliability and safety in creating, testing and launching rockets.
