The Research And Design Of Medical Diagnosis Inference Based On Pan-Boolean Algebraic

Medical Diagnosis Inference Expert System is one of the active embranchment of artificial intelligent research at present. It is an importance breakthrough that the Expert System realized practice application of artificial intelligent from academic research and realized expert knowledge application from common thinking way discussion. As hardcore of Medical Diagnosis Inference Expert System, stand or fall of Medical Diagnosis Logic Inference's capability determined the Expert System. Main research achievement is as bellows:Medical Diagnosis Logic Inference's theory is researched based on Pan-Boolean algebraic on Axiomatic, how to realize consequence applying Non-logic is put forward, and an practice design scheme and method of Medical Diagnosis Logic Inference are introduced.Research on conducted strategy of Medical Diagnosis Logic Inference is developed. We discussed forward reasoning and backward reasoning based on basic and differential diagnosis, and studied matching compare of Pan-Boolean function based on symptom and disease mapping. Simultaneity, applicable range and using way of Non-logic are studied, and how to simplified Pan-Boolean Function adopting Non-logic.The integrated Inference makes up of two parts: the host human-computer interaction interface and hardware Inference. The former, which accomplish enquiries for user and transmit answer's result of user by simply dealing to MCU, provides an alternating platform for user inputting disease's symptom manually. The later completes conduction, as well as return conducing result to the host. The host human-computer interaction interface adopt Visual Basic, while the hardware system apply PLC2124 of ARM MCU, XCR3128of CPLD and PDIUSBD12 of USB interface chip.The soft design on conducing and comparing of Medical Diagnosis Logic Inference is completed. Based on ISE Foundation 6.1 soft platform, we made research and design on the CPLD hardware Inference applying VHDL Hardware Description Language. It realized system flowing control of PLC2124 communication by applying C language, and accomplished conduction by assisting CPLD, based on ADS integrated exploration environment.The USB communication program of Medical Diagnosis Logic Inference is completed. In the USB hardware drive platform based on Windows DDK, mutual link between the hardware Inference with the host is researched and designed. Aiming to the soft modularization, we mainly realized three blockettes: the firmware program of USB device, the drive program of USB device and the communication application program of USB device. Based on the Visual Studio 6.0 software, we designed the host human-computer interaction interface, and studied the USB communication way between the host human-computer interaction interface with the hardware; the communication agreement fitting for the system is established, and realized data transmission between the host with the hardware.
