Research and development of software solution for identifying objects of material flow accounting systems based on CCSDS standards

Abstract

Although RFID hardware and software solutions for material flow and supply chain systems are widespread, their implementation today is realized at the local process and system level. When solving the problem of transmitting information about equipment between different systems, errors of inconsistency in data formats occur. This situation arises in the practical work of instrument making and space industry enterprises. There is a fragmenta-tion of the used information environments, models and methods. Today the development of new models and methods of identification of objects of material flow is important; they would provide data flexibility and the ability to integrate with existing RFID hardware systems, readers and other hardware systems. As a methodological support there have been chosen CCSDS standards, which offer solutions and development of hardware and software packages to solve the problem of identification of objects based on RFID tags. A systematic approach to representing the object identification levels has been offered and the need to develop a new system that is applicable for the identification throughout the life cycle of the object of material flow has been proved. The analysis of changing CCSDS standards in the development of hardware and software systems is presented to solve the problem of identification of objects based on RFID tags, the developed new model of data representation for the identification of the object is given, the practical implementation in the form of a subprogram is given. In addition, the possibility of adding new information about the object of the material flow is implemented, which has caused an opportunity to solve the problem of monitoring its movement in practice. The presented solution is versatile and can be used with a large number of well-known models of RFID tags. The identification system has been tested successfully so far and the results are presented in the standard CCSDS “Spacecraft onboard interface services – RFID tag encoding specification”.
