| As a major energy source in China, coal occupies an important position in the national economy. Considering mine safety monitoring status quo and the existing main problems, regarding Tingnan colliery of Shannxi as the experimental project, we designed the Coal Mine Remote Monitoring System, which integrates modern signal gathering technology, signal transmitting technology, computer information processing technology and risk forecast technology. The system, collects the field data by data collector, processes the date by central server and then transmits the monitoring data to the remote client. Depending on the system, the related workers can monitor and control the production situation of mine. The system satisfies the demands of the coal enterprise, the production of the mine can be monitored completely and real-timely.This thesis designed the whole structure of the system, and adopted the mixed mode of C/S and B/S as the system architecture. It described the software scheme of the system, which includes database system design, software functional modules design and the function of server side design. Meanwhile, taking into account the network frame and environment, researching existing data cache technology, we advanced a multi-level data cache model of distributed node, and applied the model into the system, which can relieve the task of the server, and improve the capability of the system greatly. Then, the text finished the function of the C/S structure with Delphi, and described the crucial technologies which are used in the system. The functions of the system are implemented, including displaying records of current, inquiring history records, drawing curve, counting fault records, alarming in time, safely managing system, video monitor etc. Finally, it summarized the whole text, and proposed some expectations to the subject. |
