Embodiment Construction

[0009] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the industrial site remote monitoring system of the present invention. The main hardware architecture of the industrial field remote monitoring system includes at least one field device 1, a programmable logic controller (Programmable Logic Controller, PLC) 2, a monitoring computer 3, a database server 4, a Web server 5 and at least one Monitor terminal6.

[0010] The PLC 2 is connected to at least one field device 1 . The PLC 2 adopts a programmable memory, stores a program inside it, and uses the program to write the monitoring data of the field device 1 into the PLC 2 in real time.

[0011] The monitoring computer 3 includes a data acquisition and monitoring controller (Supervisory Control And Data Acquisition, SCADA) 30 and a local database 32 . The local database 32 is used to store the collected monitoring data. The data collection and monitoring controller 30 is used to col...

Abstract

The invention relates to a remote monitoring method in an industrial site. The method comprises the following steps of: collecting the monitoring data of site equipment from a PLC (Programmable Logic Controller) by a monitoring computer; transmitting the collected monitoring data to a database server by the monitoring computer; transmitting the monitoring data received from the monitoring computer to a Web server by the database server; analyzing whether the site equipment and detection parameters are abnormal or not by the Web server according to the monitoring data received from the database server; and marking abnormal points in a monitoring picture and transmitting abnormal information to a corresponding monitoring terminal by the Web server when the site equipment or the detection parameters are abnormal.

Description

technical field [0001] The invention relates to a monitoring method, in particular to an industrial field remote monitoring method. Background technique [0002] With the popularization of automated smart devices, the scale of industrial sites has become increasingly large and complex. It is difficult for the staff on the industrial site to keep abreast of the changes in the industrial site and take corresponding measures, and the maintenance cost of the site management is also high. Therefore, a field device monitoring method for monitoring industrial field devices emerges at the historic moment. [0003] At present, the existing industrial equipment monitoring method outputs the monitoring data of the field equipment to the programmable logic controller. In the control room terminal, the industrial site is configured through the data acquisition software, and the monitoring data in the programmable logic controller is collected to perform on-site monitoring operations. ...
