Shield machine remote data acquisition system based on SCADA (Supervisory Control and Data Acquisition) system

Abstract

The invention relates to a shield machine remote data acquisition system based on an SCADA (Supervisory Control and Data Acquisition) system, and the shield machine remote data acquisition system comprises a PLC (Programmable Logic Controller), a data acquisition server and a router, wherein the data acquisition server collects, controls and monitors each item of real-time data of the shield machine in the PLC in real time; the real-time data is bidirectionally transmitted to a ground WEB publishing server by virtue of one pair of symmetric digital subscriber lines (SDSL) and is monitored; meanwhile, the real-time data is published to a local network by the router and is published to a network after being opened by a router port; and therefore, the operation state of the shield machine is remotely monitored and observed in real time. The shield machine remote data acquisition system disclosed by the invention can be used for monitoring a large quantity of data which almost covers all operation data and IO (Input Output) port state of the shield machine, and technical personnel can be guaranteed to comprehensively analyze the data. WEB publication is realized so as to bring possibility for remotely diagnosing equipment faults and analyzing operation parameters, and a platform is provided for intensively monitoring the construction quality of the project department.

Description

technical field [0001] The invention relates to a data acquisition and monitoring control system, in particular to a data acquisition and monitoring control system for shield tunnel construction. Background technique [0002] The data acquisition system adopted by the existing shield machine is relatively simple, and there is no WEB publishing function. When the shield machine is misoperated, the basic parameters of the shield operation can only be seen in the project office. [0003] In the process of shield machine repair, since a large number of electrical repair personnel are not familiar with the application of PLC programs, they can only find faults gradually under the guidance of the electrical schematic diagram and the interlocking relationship in the relevant operation manual, which is inefficient. [0004] In the past, most of the data collection interface of the shield machine was in the form of a list, and the data viewing was not visual and intuitive. Especial...
