Device for controlling the parameters of a manufacturing process

Device for continuously controlling a manufacturing process, in order to perceive continuously any transient or perturbational phenomena occurring during this process, a device comprising:

• a) a local area network;
• b) at least one remote monitor connected to said local area network through a first interface for receiving in real time signals in order to control the state of the manufacturing process;
• c) a plurality of sensors, each of said sensors being associated with one of a plurality of parameters of the manufacturing process and measuring a value of said one of said plurality of parameters and transforming said value so as to produce an analogue signal;
• d) a plurality of analogue to digital converters, each of said analogue to digital converters being connected to one of said sensors and situated proximate thereto and receiving said analogue signal in order to convert said analogue signal into a sequence of numerical values representing an instantaneous state over time of said plurality of parameters, each of said analogue to digital converters being connected to the local area network through one of a plurality of second interfaces;
• e) a plurality of actuators, each of said actuators acting on a device for modifying at least one of the parameters;
• f) a digital to analogue converter associated with each of said actuators, each of said digital to analogue converters being connected to said local area network through one of a plurality of third interfaces;
• g) processing means connected through a fourth interface to said local area network for storing and processing said sequences of numerical values and comparing said sequences of numerical values with predetermined reference values in order to generate a comparison signal, said local area network conveying said sequences of numerical values from said analogue to digital converters to said processing means and said comparison signal to said remote monitor or monitors.
