The invention discloses an automatic monitoring method for a
plant area network. The method comprises the following steps: establishing a
network architecture, establishing a
data acquisition terminalin an
enterprise private network area concerned by a manager, establishing a
data analysis terminal in an enterprise
intranet area, realizing data interaction between an enterprise
intranet and a
public network platform in a
public network area through a cloud platform or an
Internet of Things platform, and realizing a
mobile phone terminal capable of interacting with the cloud platform or
the Internet of Things platform; arranging network equipment on each layer, and determining a standard internal communication protocol; in combination with
network architecture and network detection, analyzing network faults of network nodes and levels and positions of fault points in an existing
topological graph, and pushing network fault information to mobile phones of maintenance personnel through acloud or
Internet of Things platform. According to the invention, a daily
active detection preventive mode is adopted to replace an original passive fire-fighting
processing mode that after a networkfault occurs, a service obstacle is reported, and then network maintenance personnel arrive at the site for maintenance, so that problems can be actively discovered, and the influence on on-site production and
service use can be shortened or avoided.
