Research And Development Of System For Upper Computer To Urine Analyzer

Urine analyzer is a widely used medical device to diagnose illness of human urinary system by detecting its urine chemical constituents, which can also help doctors correctly diagnosethose with diseases of urinary system. With the fast development of precision machinary technology, micro-electronics science and cornputer science, the development of urine analyzer have growing trend to high precision and full automaticity. Analyzed advantages and shortcomings of like products from different manufacturer home and abroad, this paper introduces the design of a new type upper computer of urine analyzer system which uses Windows CE as its operation system and Au1250 as its master controller.Based on the scheme proposed, key technologies of the upper computer of urine analyzer are studied. These technologies include serial port extended technology, scheme design of upper computer and lower computer communications protocol.Detailed design for hardware system is accomplished after analyzing key technologies above, which includes the main controller, external storage, man-machine interface, serial port expansion modules. After all device drivers are developed, the upper computer system function is realiszed.At last, all function modules of software system of upper computer of urine analyzer are integrated and comprehensively tested, and it is also debugged with the control and application program. This example verified the feasibility of the scheme above.
