Abstract

The invention discloses a method and a system for monitoring and diagnosing large scale equipment remotely. The method comprises the steps as follows: firstly, a PLC (Programmable Logic Controller) analyzes collected running data of the large scale equipment on an engineering site, and transmits the data to an internet by a 3G (the third generation telecommunication) wireless network; secondly, a monitoring center platform builds a safe information channel with the PLC by a VPN (Virtual Private Network) router and a VPN fire bulkhead; thirdly, the monitoring center platform analyzes and processes data passing by the safe information channel, and monitors and diagnoses the large scale equipment; and fourthly, the PLC controls the large scale equipment according to the detection and diagnosis results sent back by the monitoring center platform. The method and the system can enhance the data transmission rate and improves the data transmission safety.

Description

technical field

[0001] The invention relates to a method and system for remote monitoring and diagnosis of large equipment, belonging to the field of remote monitoring and diagnosis. Background technique

[0002] The monitoring and diagnosis mode of large-scale mechanical equipment (material handling equipment, mechanical engineering equipment, mining equipment, etc.) has experienced a development process from stand-alone monitoring and diagnosis to distributed monitoring and diagnosis, and then to network-based remote monitoring and diagnosis. In recent years, with the rapid development of Internet communication technology and wireless network, people have begun to study and practice remote fault diagnosis methods, among which how to realize the transmission and processing of various field data, remote control, and field device Remote maintenance is a matter of great concern to people.

[0003] However, in the current remote monitoring and diagnosis mode, the transmission ...
