A food handling control system

摘要

A food handling control system (1) has various sensors and control units (3-7) in a food handling environment. Parameter values are routed to an on-site monitoring system (9) which logs the data in real-time sequential order. It also checks for wide divergence from control conditions and generates an early alarm. A data communications controller (10) routes data to a status process (11) which generates control signals for the control units. The data communications controller (10) has a sample and hold circuit for receiving parameter values and a parallel and alarm monitor for bypassing the sample and hold circuit to route an alarm signal from a sensor directly to the status processor (11).
