The invention discloses an
information management system for on-line production of a printing
machine, which is characterized in that a
web server and an upper management browser terminal which are mutually connected are arranged in an MES internal
Ethernet to be used for realizing on-line
remote diagnosis and maintenance; the MES internal
Ethernet is respectively connected with an OPC
server and an equipment
station browser terminal, and the MES internal
Ethernet is also connected with an equipment
industrial Ethernet of a plurality of printing
machine units through the OPC
server; an Hub, an HMI, a CPU and a controller are arranged in the equipment
industrial Ethernet; the Hub is externally connected with the OPC
server; the Hub is respectively connected with the HMI, the CPU and the controller; and the controller is connected with a PLC
control system in the printing
machine equipment. The invention also discloses a method of on-line control and real-
time data acquisition of the
control system. The invention realizes the real-time
network monitoring, parameter reporting, production management and analytic statistics under the B / S structure in an
Ethernet communication mode, and realizes multi-browser and multi-user operation.
