摘要
针对市场中现有血液透析机校准装置工作效率低,检测人员不能在一个设备上同时检测多个参数的问题,利用STM32和RT-Thread设计一种可在现场同时检测多参数的血液透析机校准装置。校准装置的硬件系统按照模块化进行设计,分为血液透析机检测仪控制器与血液透机检测仪两大硬件系统,它们之间通过无线传输模块进行通信。软件系统利用RT-Thread实现任务调度,保证多任务的有序执行,提高系统的实时响应能力。实验结果表明,校准装置能够完成JJF 1353-2012《血液透析装置校准规范》要求,具有较高的实际应用价值。
To address the problems of low efficiency of existing hemodialysis machine calibration devices in the market and the inability of testers to test multiple parameters simultaneously on one device,a hemodialysis machine calibration device that can test multiple parameters simultaneously in the field is designed using STM32 and RT-Thread.The hardware system of the calibration device is designed according to modularity and divided into two hardware systems:hemodialysis machine tester controller and hemodialysis machine tester,which communicate with each other through a wireless transmission module.The software system uses RT-Thread to achieve task scheduling,which ensures the orderly execution of multiple tasks and improves the real-time response capability of the system.The experimental results show that the calibration device can fulfill the requirements of JJF 1353-2012 Calibration Specification for Hemodialysis Devices and has high practical application value.
