Abstract

The invention relates to a multi-bus microwave metallurgical control system and method. The system comprises a main control computer, a database, a plurality of programmable controllers, various sensors, relays and a microwave metallurgical device; the main control computer is provided with a plurality of communication ports; and the programmable controllers and the main control computer are connected by a multi-bus way. The main control computer consists of an interface display module, a buffer zone establishment module, a data acquisition module, a control decision module, an instruction sending module, and a Web query service module. Data acquisition, instruction sending, user interface management, and control decision operations are carried out at different threads; and data interaction and coordination consistency among the threads are realized based on a global instruction sending buffering list and a global data receiving buffer list. According to the invention, a multi-thread dual-buffer mechanism is employed, so that the data communication capability and the processing capability of the multi-bus control system can be effectively improved; and because of utilization of the dual-buffer mechanism, the program structure is optimized and the coupling degrees among the program modules are reduced.

Description

technical field [0001] The invention relates to a multi-bus-based microwave metallurgy control system and method, belonging to the field of control technology. Background technique [0002] Due to the large number of data acquisition points and control points of microwave metallurgy or drying heating devices, in order to improve the performance and data processing capabilities of the control system, a multi-bus microwave metallurgical control system was proposed in patent ZL 201220630008.2. This multi-bus structure is effective The communication ability between the main control computer and the programmable controller is improved, and the performance of the system is improved. When the main control computer communicates with the programmable controller on the multi-bus, it usually adopts the method of polling the communication port, and because the devices controlled by the programmable controller on the bus are different, some respond quickly and some respond slowly , and ...
