According to the requirement of digital real-time monitoring and control of Magnesium smelting furnace smelting process for control of the heating system power regulation, furnace multi-point temperature, pressure and other physical parameters of the dynamic change. This paper developed a magnesium smelting furnace remote monitoring system based on C/S architecture. The use of digital industrial control design concept which helps the system could realize multi-parameter data acquisition, monitoring and control, data recording automatically and statistical analysis, event tracking, video surveillance and remote network sharing. The hardware system of Magnesium smelting furnace includes multi-machine communication system consisting of PLC-based master controller and a variety of intelligent devices, furnace circulating cooling system, preheating cabin lifting sub-system controlled by electrical-hydraulic and high-powered vacuum machine controlling sub-system. In order to facilitate field wiring and system upgrades, a intelligent controller of electric valve has developed independently based on AVR microcontroller for connecting the complex electric valve, which enabling remote control and monitoring for multi-valve via the field bus. Magnesium smelting furnace application system software using multi-level platform which includes multi-parameter measurement online, actuators digital control, remote network share . As the core of central control of the magnesium furnace system, PLC collects multi-channel data from intelligent valve controller, temperature modules, vacuum indicators, voltage of power grid, current detectors and DC power measurements. After data processing, PLC compares the data with the predetermined control parameter, then exports it. It could get automatic control of heating power of large high-power DC power, switch of the multi-channel valves of the transportation of the materials, high-powered vacuum machine, and out of the feeding mechanism and other mechanical equipment. PLC transmits data to host computer via RS232 to display, record and remote share. Remote client communicates with server by using Socket network communication and database access based on ADO technology to achieve magnesium smelting furnace smelting process automation and remote dispatching. The system has been put in the Engineering Research Center of Xi'an University of Science and Technology garnierite industry use more than a year, the actual use of 12 heats, field testing and refining magnesium smelting operations which supplied by the network computer platform is operating normally. It provides a new approach for relevant equipment manufacturing in terms of quality and process optimization.
