Production line monitoring method, remote client, server and upper computer

Abstract

The invention provides a production line monitoring method, a remote client, a server and an upper computer. The method comprises the following steps that: S200, the remote client sends a monitoring request message to a server; step S300, the server obtains a response message corresponding to the monitoring request message according to the monitoring request message and based on the result of information interaction between the server and the upper computer; and the server sends the response message to the remote client. With the production line monitoring method, the remote client, the server and the upper computer provided by the invention adopted, professional and technical personnel or operating personnel can conveniently carry out remote monitoring and remote control on a production line and can timely provide technical guidance for a site through the remote client, and therefore, centralized maintenance can be realized, and the security of the operation of a system can be improved, the work efficiency and operation condition of factories can be improved, and social economic benefits can be increased.

Description

technical field [0001] The invention relates to the field of field automatic control, in particular to a production line monitoring method, a remote client, a server and an upper computer. Background technique [0002] In the operation of an industrial production line, the cooperation of the upper computer and the lower computer is needed to realize the operation control of the production line. The upper computer refers to the computer that can directly issue control commands, usually a personal computer. The screen of the upper computer displays various Signal changes (e.g. hydraulic pressure, water level, temperature, etc.). The lower computer is a computer that directly controls the device to obtain the status of the device, and is generally a PLC (PLC Programmable Logic Controller, programmable logic controller) / single-chip microcomputer and the like. The command issued by the upper computer is first given to the lower computer, and then the lower computer interprets th...
