Design of an urine drop auto-detection and analysis system based on computer

Computer and electronic technology was adopted to automatically detect and analyze urine of animal during physiological experiment. A photoelectric urine drop collector and detector was designed to detect signal of urine drops. The signal was amplified and sent to a computer for further processing. Visual Basic and Borland C + + language were used to design software interface and I/O control. The system had many functions, such as parameter setting, sampling, saving and playing back data. Experiments showed that the system could collect and record urine drops accurately. The system is easy to operate, very automated, and meets the requirements of physiological experiments.
