Local area network remote monitoring system based on SIEMENS840D numerical control system

Abstract

The invention discloses a local area network remote monitoring system based on an SIEMENS 840D numerical control system. The local area network remote monitoring system is composed of a hardware partand a software part. The hardware part comprises a monitoring center and a plurality of independent local area networks connected with the monitoring center, and each local area network comprises a plurality of devices adopting the SIEMENS 840D numerical control system and connected by network equipment and a special server; the software part is remote monitoring software; and the monitoring center accesses the host of each device adopting the SIEMENS 840D numerical control system by accessing the special server, remotely monitors the device, checks device fault and related information, and diagnoses and preprocesses the fault. According to the invention, the fault processing efficiency is improved, the fault repair time is shortened, the equipment shutdown rate is reduced, and the workingefficiency of equipment maintenance personnel is greatly improved.

Description

technical field [0001] The invention relates to remote monitoring of a numerical control machine tool, in particular to a local area network remote monitoring system based on a SIEMENS 840D numerical control system, which belongs to the technical field of numerical control machine tools. Background technique [0002] At present, when the CNC machine tool equipment on the job site fails, see figure 1 , The repair process of equipment failure is that the operator fills out the warranty form and informs the maintenance personnel of the failure phenomenon of the equipment by telephone. The maintenance personnel judges the cause of the failure based on the information provided by the operator, and then arranges the corresponding maintenance personnel to go to the scene for repair. [0003] The existing equipment maintenance mechanism has the following disadvantages: the on-site operator cannot describe the failure phenomenon clearly, and the important information is missing when ...

Problems solved by technology

[0003] The existing equipment maintenance mechanism has the following disadvantages: the on-site operator cannot describe the failure phenomenon clearly, and the important information is missing when the maintenance is reported; when the CNC system fails, sometimes several alarm signals may appear at the same time, and the operator may only mention After receiving an alarm message, the maintenance personnel cannot correctly judge the cause of the fault, so they must arrange personnel to go to the scene to confirm the fault phenomenon, then make a fault judgment, formulate a maintenance plan, and then arrange repair personnel and corresponding spare parts to eliminate the fault, thus costing A lot of time is spent on understanding the fault situation and fault diagnosis
