【摘要】：目前心脑血管疾病对人类危害越来越大,血小板功能的检测对该类疾病的预防、诊断和治疗都具有重要意义,因此血小板功能分析仪在医学临床应用中需求广泛。论文结合企业新产品开发需求,在单通道血小板功能分析系统技术基础上,应对大样本快速检测环境下实现两个不同血样的高精度和重复性要求,系统地研究了双通道全自动血小板功能分析仪控制系统的设计和实现。分析仪控制系统由控制机系统和管理机系统两部分组成,两者通过SPI接口以主从方式通信。控制机由DSP控制器TMS320F2812、执行机构驱动电路、信号调理采集电路、辅助电路等几部分组成；管理机采用S3C2410(ARM9)嵌入式处理器,并移植嵌入式Linux操作系统、Minigui图形接口中间件及嵌入式数据库Sqlite,实现功能开发与升级。本文首先介绍了血小板功能分析的意义和发展现状,以及基于血小板计数法的单通道血小板分析仪工作原理。然后,基于经济型开发模式,讨论双通道全自动血小板功能分析仪的需求和功能,设计并论证系统解决方案的可行性。其次,论述了双通道测量控制电路的设计原理,较好地实现了双通道四路信号的高性能处理和采集。在控制机软件设计中,主要实现以下功能：执行机构的控制以完成混匀、测试、清洗、维护等流程；信号的处理和采集算法；温度、负压、高压灼烧等辅助电路的控制。在管理机软件设计中,详细介绍了各模块的设计原理,升级实现了人机交互界面、测试流程管理、数据管理、SPI通信、以太网通信等功能。最后给出了控制系统性能调试与测试结果的分析。另外,本文还探讨并介绍了通过联机管理软件实现对多台仪器群控的方案。
[Abstract]:At present, cardiovascular and cerebrovascular diseases to human health is more and more big, the prevention of platelet function of this kind of disease, has an important significance in diagnosis and treatment, the platelet function analyzer in clinical application. Combined with the demand for the development needs of a wide range of new products, in the platelet function analysis technique based on single channel system, rapid detection of environment to deal with large samples to achieve two high accuracy and repeatability of different sample requirements, systematically studies the design and implementation of dual channel automatic platelet function analyzer control system. The control system consists of two parts, instrument control system and machine management system, both through the SPI interface with master-slave mode communication control machine by DSP. TMS320F2812 controller, actuator drive circuit, signal conditioning circuit, auxiliary circuit; management machine using S3C2410 (ARM9) block Embedded processor, and embedded Linux operating system, Minigui graphical interface middleware and embedded database Sqlite, realize the function of development and upgrade. This paper firstly introduced the significance and development status of platelet function analysis, and the working principle of single channel analyzer platelet platelet count based on the method. Then, the economic development mode based on the demand and function discussion double channel automatic platelet function analyzer. The feasibility of the solution system is designed and demonstrated. Secondly, discusses the design of control circuit of dual channel measurement principle, realizes four dual channel signal acquisition and processing of high performance. In the design of control software, mainly to achieve the following functions: to control the actuator complete mixing, testing, cleaning, maintenance and other processes; signal processing and sampling algorithm; temperature, negative pressure, high burning burning and other auxiliary circuit The control. In the management of software design, introduces the design principle of each module, upgrade the man-machine interface, test process management, data management, SPI communication, Ethernet communication and other functions. Finally, the analysis of the performance of the control system debugging and test results are given. In addition, this paper also discusses and introduces the the instrument control scheme is implemented by the online management software.
