Labour Monitor Based On Windows CE With Host-Slave Structure

Derived from the electrical activity generated at the muscle fiber lever, uterine EHG can reflect the process of excitement on muscle fiber and provides complementary information on the muscle. Since the inspection function of EHG is non-invaded., which record the electric activity of uterus by electrode on the body surface of pregnant woman. Compared to the current invasive monitoring, it's a better means to investigation of the uterine activity.In order to make use of EHG to monitor the activity of uterine and diagnose process of labour ,this paper desigens a monitoring system for EHG, which analyse the intensity and frequency of EHG and the conherence of the uterine constriction. In order to process and harmonize multiform mission and make use of the abundant hardware resource, ARM processor is introduced to our system. ,meanwhile windows CE operating system is embedded in the ARM system to simples development and operation. But the Windows CE operating system reduces the real-time ability, so ADuC841 single-chip MCU is adopted to realize the data acquisition.Host-slave mode is adopted in our system, with the host machine using ARM to realize complex tasks and the slave machine using 51 MCU to gather data. Moreover the graphy topology is used to analyzed the EHG. My teacher, Professer Li gang,first introduct to use the graphy topology function to analyse the EHG, and my teacher,Jiang wei, discuss the feasibility and establish mode .In this paper I have a try to realize it in our application program..The host-slave EHG monitor, with abundant function, easy take-way, low cost, as well as stable and safe capacity, makes a fine figure.
