Design And Implementation Of Portable Biochemistry Analyzer Control System

Biochemical analyzer is undoubtedly the most frequently used in all laboratory equipments, it has the widest detection range as it is the most representative equipment. Medium-sized hospitals generally choose high speed and high reliability equipments which are imported, the small hospitals are gradually also transition from semi-automatic biochemical analyzer to small automatic biochemical analyzer. Although the biochemical analysis has been development for many years and at the peak period, but compared to other analytical tools, it has a less cost and mature technology advantages, so it is still irreplaceable in the coming decades.Currently ordinary automatic biochemical analyzers which hospital normally used need liquid reagent, flow of distilled water, large area. The advantage is the ability of batch processing capability, the disadvantage is that it need permanently installed in the hospital laboratory, less flexibility, and can not a report soon.The system is the designed to solve these problems, according to a large automatic biochemical do not have small, fast out of the report, low cost considerations, control system design portable biochemistry analyzer.The main contents are as follows:1. First, a detailed description of the portable biochemical analyzer system configuration, indicating portable biochemical analyzer is able to quickly detect and timely reporting of the principle. And combining the analysis supplies the entire system, clear the entire control system needs to achieve the critical performance parameters, establish various key steps to ensure that the device can be run in accordance with the expected flow and achieve the expected effect.2. Subsequently, the introduction of portable biochemical analyzer circuit control system components, analyzing the advantages and disadvantages of portable biochemistry analyzer modular design, and by principle, this demonstrates the reliability and stability of the closed-loop system, from circuit design optimization and elaborate on the entire schematic design.3. In addition, based on the design of hardware schematics, circuit board was planning the whole control system, combined with the structure size and installation, carried out to optimize PCB design.4. At the same time, based on the entire hardware platform, especially front-end hardware platform control portion used for ARM processor-controlled test flow line simulation, and FPGA control signal for acquisition, processing algorithms with modelsim simulation and implementation, analysis of the entire Reliability timing and signal integrity, integrity.5. Finally, summarize the advantages of the system, analyze shortcomings and follow directions for improvement may exist. And in relation to other possible applications equipment for analysis, pointed out the future development direction.
