Hashed Data Transfer in SHM Distributed Systems with the Use of Power Line Communication Technology

Abstract:

Structural Health Monitoring of distributed systems is closely connected with data transmission from measurement points to the main server, where measurement data is processed and subjected to expert assessment. Power Line Communication (PLC) technology allows data transmission through existing power network. The greatest advantage of the PLC technology is the possibility of using ubiquitous, electric infrastructure, wherever there is no access to dedicated wired transmission links. However, it should be stressed that the main application of power lines is transmission of electricity while data transmission is a secondary issue. In monitoring systems and distributed measurement systems it is of vital importance that information from measurement points reaches the receiver in the unchanged form. Hash functions rise possibility of proper recognition if transmitted data is an exact mapping of information sent from measurement point. The paper concerns the method of polynomial hash function implementation for PLC systems in the LabVIEW environment.
