The article deals with the issues concerning construction of a computer complex using sequential analysis for recognition of technical systems states in real time based on the data received through wireless sensor networks. A computational complex has been designed to detect the regularities in the output signals of sensors using sequential functions. The obtained data are also used to detect abnormal states including exception and alarm situations. An algorithm was developed for obtaining a basis for sequential functions, with the help of which it is possible to determine the state of the object under study. The algorithm uses spatial sequential transformation over specially ordered signals coming from sensors via wireless sensor networks. This helps to form a sequential spectrum, which is represented as a linear function by means of a diagonal procedure for sequencing the spatial sequents (frequencies). The analysis of real-time readings of sensors and the rapid calculation of functions allow to evaluate the system state, which is of great use, in particular, in the fault-detection. The results of computational experiments prove the efficiency of the developed computer complex and its applicability for technical systems states analysis in real time.
