1. a hand-held Urine Analyzer, comprise and be arranged on single-chip microcomputer in casing (1) and by monolithic processor controlled test paper conveyer, optical acquisition device (12), LCDs, data memory module, described test paper conveyer comprises slide rail (11), along the test paper pallet (4) that slide rail (11) slides, the tooth bar (6) connected as one with test paper pallet (4), and the gear (9) driven by motor (10) that the driving test paper pallet (4) to coordinate with tooth bar (6) passes in and out, described optical acquisition device (12), motor (10), slide rail (11) be arranged on be positioned at casing (1) support (13) on, it is characterized in that:

  • described test paper pallet (4) is also fixedly installed a magnet (8), support (13) is provided with the Hall element (7) corresponding with magnet (8), described Hall element (7) is connected with single-chip microcomputer and communicates, the program design of described single-chip microcomputer has the startup self-detection program, test paper tray position trace routine, light reflectivity automatic calibration program, test paper position trace routine, test paper color lump automatic calibration program and the urine detection program that start successively,Described test paper tray position trace routine is detected the position of magnet (8), thus make test paper pallet (4) be in the zero position corresponding with optical acquisition device (12);

    Described test paper position trace routine runs complete, test paper pallet (4) in test paper tray position trace routine to be on the basis of zero position, by the shift-in of test paper pallet with shift out the test paper that detection is positioned on test paper pallet (4) and whether align with optical acquisition device (12)Described light reflectivity automatic calibration program the standard grayscale bar of known reflectivity standard value is placed into test paper pallet (4) go up and be transported to the position corresponding with optical acquisition device (12), optical acquisition device (12) detects standard grayscale bar, by detect R, G, B tri-color light reflective rate and known reflectivity standard value compare calculating, obtain R, G, B tri-correction factor of coloured light, this correction factor is stored into data memory module, calls to revise testing result for during follow-up operation urine detection program;

    Described test paper color lump automatic calibration program is that each color lump is divided into some check points, the waveform of each check point on this color lump compares and determines the center of color lump after carrying out the waveform of each check point of detection formation by all check points of optical acquisition device (12) to each color lump;

    During normal work, after startup self-detection program finishes execution, start test paper tray position trace routine, then light reflectivity automatic calibration program, test paper position trace routine, test paper color lump automatic calibration program is carried out, urine detection program is carried out in color lump center alignment light harvester (12) of tested test paper by last test paper conveyer, urine detection program detects the reflectivity at color lump center, and testing result outputted in LCDs and data memory module.
