摘要：国家要求医疗污水需经处理后方可排放 , 目前国内大部分医院采用二氧化氯处理医疗污水, 检查二氧化氯消毒的效果及是否产生二次污染是通过检测处理后的废水中余氯的含量来判定的。 由于污水中成分较为复杂 , 在线检测废水中余氯的问题始终困扰着人们。 本文介绍了一种在线检测医疗废水中余氯浓度的设计, 该设计是借助试剂发色可见波长范围内光吸收的原理检测医疗废水中的余氯,以单片机为主控制器,控制系统复位机构实现在线连续检测、信息显示及远传、废水达标排放等。
借助系统模型，阐明GSM模块收发短信的基本概念以及串口控制SMS的基本原理。详细介绍单片机控制GSM模块工作的硬件和软件的实现过程，对怎样用单片机控制GSM模块收发短信进行了深刻的探讨，也对程序设计的主体思想作了较为细致的分析。

Medical Sewage On-line Detection System
Abstract:Countries require medical sewage to be treated before discharge, at present, most of domestic hospitals by chlorine dioxide medical waste water treatment, examination of chlorine dioxide disinfection effect and whether secondary pollution is determined by the content of residual chlorine in detected after treatment of waste water. Due to the waste water complicated composition, the residual chlorine in the online detection of waste water always plagued the people. This paper introduces the design for on-line detection of medical waste water residual chlorine concentration, the design is the residual chlorine reagent with the help of hair colors within the visible wavelength range optical absorption detection principle in medical waste water, with MCU as the main controller, control system reset mechanism implementation Continuous on-line detection, information display and remote transmission, waste water discharge standards.
With the system model to clarify the GSM module send and receive text messages to the basic concepts and SMS port basic principle. Detailed introduction of SCM control GSM module hardware and software implementation process, on how to control the use of single-chip GSM transceiver module SMS were profound discussion, also on the program design of the main ideological and more detailed analysis.
