Utilization is gathered, is analyzed to reach Centralized Monitoring, remote analysis, expert purpose such as check on the shield machine service data based on the configuration software of SCADA (data acquisition and supervisor control) system, and control has more positive meaning for the shield-tunneling construction Quality Process.
Summary of the invention
The present invention will provide a kind of shield machine remote data acquisition system based on SCADA data acquisition and supervisor control system, and these system monitoring data contain all service datas and the IO port status of shield machine, guarantees that the technician can comprehensive analysis data; To a certain phenomenon of the failure the maintenance reference is provided, repair method efficiently is provided, guarantee the operational reliability of shield machine the shield machine maintenance personal; Embed animation display; The shield machine running status is more directly perceived, is convenient to the understanding to shield-tunneling construction technology, realizes the WEB issue; For the remote diagnosis equipment fault, analyze operational factor and bring possibility, to the Centralized Monitoring of project management department's construction quality platform is provided.
For realizing above-mentioned purpose; Technical scheme of the present invention is: a kind of shield machine remote data acquisition system based on the SCADA system comprises the PLC program controller, data acquisition server; Router; Be characterized in: data acquisition server is gathered the also control of shield machine each item real time data, monitoring in real time in the PLC program controller, also implements monitoring through a pair of Symmetric Digital Subscriber Line (SDSL) transmitted in both directions to ground WEB publisher server, issues to LAN through router simultaneously; To the network issue, reach remote monitoring and real-time monitored operation conditions through the open back of routed port to shield machine.
Both-way communication between data acquisition server and the PLC program controller is set up the communication data storehouse through data acquisition and supervisor control (SCADA) software, carries out real-time Data Transmission with the DDE mode.PLC program controller link module adopts serial communication modular, and data acquisition server adopts RS232 serial ports and PLC to set up communication linkage.
SDSL router point-to-point communication pattern is adopted in communication between data acquisition server and the WEB server.
The present invention compares the beneficial effect that has with the available data acquisition system:
System monitoring data volume of the present invention is big, has almost contained all service datas and the IO port status of shield machine, guarantees that the technician can comprehensive analysis data.
System of the present invention has embedded the drawing of hydraulic circuit, the electric diagram of cutterhead major loop; The operation conditions of each valve member, electric component comes into plain view; Particularly embedded help screen at the warning picture; To a certain phenomenon of the failure the maintenance reference is provided, repair method efficiently is provided, guaranteed the operational reliability of shield machine the shield machine maintenance personal.
System of the present invention has embedded more animation display, and the shield machine running status is more directly perceived, is convenient to the understanding to shield-tunneling construction technology.
Added the demonstration of one minute form, the inquiry of history report, one group of report data collection one minute has the characteristics of continuity, is convenient to the data correct analysis.
Add that second real-time curve demonstration, history curve inquiry, maximum value, minimum value, average are calculated automatically, laterally vernier, vertical proportional zoom, data analysis is more directly perceived.
Realized the WEB issue, for the remote diagnosis equipment fault, analyze operational factor and bring possibility, platform is provided the Centralized Monitoring of project management department's construction quality.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, the shield machine remote data acquisition system based on SCADA system (data acquisition and supervisor control) of the present invention comprises the PLC program controller, data acquisition server, router, WEB server, SDSL (Symmetric Digital Subscriber Line) etc.
The direction of arrow is the communication data transmission direction in the SCADA block diagram.Data acquisition server is gathered the real time data in the PLC program controller and is participated in control, monitoring in real time; Job site shield machine real-time motion situation, shield-tunneling construction parameter, equipment operation situation and integrated treatment shield-tunneling construction information are obtained in collection; With the data that obtain through a pair of SDSL (Symmetric Digital Subscriber Line) transmitted in both directions to ground WEB server and implement monitoring; Issue to LAN through router simultaneously; To the network issue, reach the purpose of remote monitoring through the open back of routed port.Guarantee that each item monitor data can be transferred on the computer of corporate HQ Surveillance center to realize the function of unified monitoring, centralized management smoothly.
This system is at present through the actual use about totally 5 kilometers of three shield structures.This system mainly utilizes the configuration of configuration software to accomplish the collection of each association of shield machine, and is sent to ground office through a pair of SDSL, make the constructor at the scene office can observe the operation conditions of shield machine in real time.Transmission range is in 8 kilometers.This system gathers more than 500 real time data altogether, has almost contained all driving output, signal feedback, the technical datas of shield machine.At present, this system has accomplished the WEB issue, can be on network each item service data of real time monitoring shield machine, reached long-range strange land monitoring truly.
