Development Of The Ultrasonic And Peripheral Control Subsystem Of The Whole Automatic Pathological Tissue Processing System

Pathological tissue processing includes the selection of tissue samples, dehydration, embedding sealing wax and other multiple process. The quality and processing speed of pathological process, directly affect the patient's diagnosis and treatment, is a very important step in the analysis of Medicine. Research on rapid and automatic pathological tissue processing system is a research subject with important medical value. Pathological tissue processing system relates to the mechanical design and manufacturing process,biological and pathological science, sensor technology, embedded system,which is involved in a multi discipline comprehensive subject. The ultimate goal is to make a fast processing speed, automatic pathological tissue processing equipment, effectively improve the quality of the pathological tissue processing, shorten the processing time of the pathological tissue processing. Through the analysis of pathological tissue processing, built a master and several slaves' pathological tissue processing system. This paper introduces in detail the pathological tissue processing system from circuit design, machine part of the program, and introduces some key technologies of the pathological tissue processing system.Firstly introduces this topic source and the research significance of pathological tissue processing system. Summarizes the current domestic and international situation of pathological tissue processing system. Draw on the advantages of the existing equipment, and hope to carry forward the advantages in the design of the system, improve the shortcomings of existing equipment.Secondly, this paper introduces the concept of pathological tissue, as well as the pathological process of the organization. Summarizes the pathological tissue processing system of the main mechanical structure design, programs for the entire electrical system framework.Third, using ultrasonic oscillation method, speeds up the pathological process. Design ultrasonic drive,and solve the problems of the driving circuit, finally come up with the best solutions. The realization idea of the ultrasonic driving software is given. Following developer can directly control the switch type load, in accordance with the requirements of the interface.The fourth part, design driving circuit for some switch type load of the pathological tissue processing systerm,and introduce the work flow of the specific function module.Shield switch type load,through the way of hardware driver, and attached to the driver source code.Fifth, through a validation work, validate the correctness of circuit design, validate the correctness of system transplantation, validate the correctness of the program code. Project team members participate in the joint debugging of pathological tissue processing system, including communication test, and the stability of the long running test.Sixth, make a summary of the project, and put forward the way how to improve the project.
