The system software uses typical foreground / background model . the main program serves as background and interrupts " isrs serve as foreground . system program responses all measuring , controlling , communicating and displaying tasks in time through switching between foreground and background and queuing tasks in terms of priority level 在软件组织上，采用典型的前后台模式，以主程序作为后台任务，中断服务程序作为前台任务，通过对前后台任务的及时切换以及对前台任务进行优先级排序，达到及时响应系统测量、控制、显示等一系列任务。
The use of mcu makes the induction cooker intelligence , mainly offers good man - machine interface , power automatic control and temperature automatic control , time control as well as various automatic detections alarm etc . this system covers many fields such as electronics , mechanicals , magnetic , algorithms etc . mcu program structure divides into two parts as main program and timer interrupt service program , after many times " testing and running , the program runs steadily and reliably 单片机的使用让电磁炉实现了智能化，主要包括提供良好的人机界面、功率自动控制、温度自动控制、定时控制以及各种自动检测报警等。该系统覆盖了电、机、磁、算等多个领域的知识。单片机程序结构分主程序和定时器中断服务程序两个部分，经过反复试验运行，程序运行稳定可靠。
On the basis of advanced electric control technology , my works are carry on analysis and design about the hardware and software of ecu . the idle speed control aim is make gasoline keep well property under the low rotation . in accordance with 465q gasoline specific conditions , we take use of fuzzy control theory on idle speed control of gasoline , and make step - motor to idling executive body . appling intel 80c196kb chip , we program idling the main order , software time implement break sub - order and delay sub - order in compilation language 怠速控制的目的则是保证在较低的转速下保持汽油机具有良好的性能，我们在分析465q汽油机的具体情况的基础上，把模糊控制理论用在汽油机怠速控制方面，用步进电机作为怠速执行机构，并以intel的80c196kb单片机为主芯片设计了怠速控制系统的软硬件，用intel汇编语言设计了怠速主程序，软件定时器中断服务程序，三相单三拍步进电机正反转子程序，延时子程序汇编软件。
Software part want function that realize : through interrupt service routine gather and come out regularly ecg signal , store among computer in the form of the binary scale ; data compress programme should realize to ecg signal pretreatment and compress of signal , narrow the storing amount of the data , save the space ; case information management system realize patient information and heart telecommunication file of interest , keep and in the data base , can show the ecg signal wave form at the screen of the computer directly data that gather . and has offered and type and report the single function 软件部分所要实现的功能为：通过中断服务程序把心电信号定时采集出来，以二进制的形式存储在计算机中；数据压缩程序应实现对心电信号的预处理和压缩，缩小数据存储量，节省空间；病例信息管理系统实现患者个人信息和心电信息的存档，把采集的数据保存作数据库中，能够将心电波形直接显示在计算机屏幕上，并提供打印报告单的功能。
On the aspect of hardware , it refers to the hardware circuit design of the high - speed control card and the analog output card , anti - jamming technology , chip software programming , and hardware upgrade project ; on the aspect of software technology , it relates to the design idea of program frame modularization and using asm96 assembly language to compile system software including main program and communication interrupt service program and controlling output program 硬件上，内容涵盖了高速智能控制卡和模拟量输出接口卡的硬件电路设计、抗干扰技术、芯片控制程序设计和硬件升级方案;软件上，注重程序结构模块化，运用asm96宏汇编语言编写系统程序，包括主程序、通信中断服务程序、控制输出程序等。
