Module for monitoring industrial processes

Abstract

A module for monitoring industrial processes for use in a system for monitoring industrial processes that comprises sensor means () for detecting process quantities in a process station (), acquisition means (″) for acquiring measurement signals (R) issued by said sensor means (), processing means () operating on signals (T; T) generated by said acquisition means (″) to obtain information on the quality of the process, and means for managing the production flow (), which operate on the basis of said information on the quality of the process and are located in a workstation () that is remote with respect to said process station, said monitoring module () being configured for being set locally at said at least one process station () for receiving measurement signals (R) issued by said sensor means (). Said monitoring module (), set locally at said process station () comprises means (″) for acquisition and processing of the measurement signals (R), which in turn comprise means () for encoding said measurement signals (R) generated by said sensor means () into encoded signals, and wireless transmission means () associated to said acquisition means (″) configured for sending the encoded signals (T; T) generated by said acquisition means (″) to corresponding wireless receiver means () comprised in said remote workstation () that comprises said means for managing the production flow () and said processing means (), which operate on signals (T; T) generated by said acquisition means (″) to obtain information on the quality of the process, said acquisition means (″) comprising a voltage-to-frequency converter () for converting said measurement signals (R) into a pulse train (T) at a variable frequency greater than or equal to 65 536 Hz.
