| Aiming at the shortcomings of numerous agreements and poor compatibility between different agreements of the fieldbus, owing to the intelligence fore-end platform with the microprocessor of AT91RM9200 ARM as core, into which the embedded operating system of Linux is transplanted, configuration text of superordination machine download arrives at intelligent instrument, and corresponding control algorithm is called according to configuration text, so as to implement special control function. Scheduling principle of intelligent instrument algorithm is analyzed and represented in this paper. The structure of intelligent instrument is designed, definition and structure of configuration text and algorithm function block is brought forward, and scheduling of algorithm function block is realization; the Client/Server network communication is built; the program is ran under Linux, which verifies the feasibility. |
