The Design Of Coal Production Remote Monitoring System

As a kind of non-renewable energy, in our country economic development coal plays an irreplaceable role, but the production safety accidents happened one by one. In order to regulate the production of coal mining enterprises and prevent illegal exploitation and over-exploitation which cause production safety accidents. Relevant departments put forth to speed up the pace of coal mine production information.As an important coal production information device, The coal production remote monitoring system in this paper can real-time monitor coal production and prevent coal mining enterprises producing extra coal. This system mainly consists of three big parts, they are:coal mine production data acquisition equipments which are in the field of coal production, main station in the central control room and the coal production remote monitoring web site.Firstly this paper introduces the the overall structure and function of coal production remote monitoring system, then will introduce the principle and development details of them and the key equipments in the three big parts. In the three big parts the paper will focus on the following contents: 1. The data collection equipments in the coal mine■Introducing the design principle of flameproof and intrinsically safe+5VDC power with recovery function, focusing on the circuit design principle and development details of the anti-jamming circuit and the recovery function circuit that runs when the power is in the over-current protection and overvoltage protection state;■Introducing the design principle of intrinsically safe data collection module, focusing on the design principle and development details of the anti-jamming circuit, denoising algorithm and the application software;2. The main station in the central control room■Introducing the design principle of coal information transmission interface, focusing on the design principle and development details of the protocol and application software that used to receive data and transmit data;3. The coal production remote monitoring web site■Introducing ASP.NET technology and the principle of the coal production remote monitoring web site that developed with ASP.NET technology, focusing on the development details of the video monitoring page that belonged to the Web site.Finally this paper makes a summary and prospect.
