手把手教你学Simulink--基于Simulink的智能家居远程医疗辅助系统仿真建模

 modelName = 'SmartHome_RemoteHealthMonitoring';

    
 new_system(modelName);
    
 open_system(modelName);

 % 添加心率信号源模块，使用Sine Wave模拟心率变化

    
 add_block('simulink/Sources/Sine Wave', [modelName '/HeartRate']);
    
 set_param([modelName '/HeartRate'], 'Amplitude', '60'); // 假设平均心率为60次/分钟
    
 set_param([modelName '/HeartRate'], 'Frequency', '1/(60*60)'); // 心率周期设置为60秒

 % 添加MATLAB Function块

    
 add_block('simulink/User-Defined Functions/MATLAB Function', [modelName '/AnomalyDetection']);
    
  
    
 % 编辑MATLAB Function块的内容
    
 function alert = fcn(healthData)
    
     % 在这里编写你的异常检测算法
    
     threshold = 100; // 设定心率阈值为100次/分钟
    
     if healthData > threshold
    
     alert = true;
    
     else
    
     alert = false;
    
     end
    
 end

 % 添加Display块显示报警状态

    
 add_block('simulink/Sinks/Display', [modelName '/AlertStatus']);
    
  
    
 % 配置MATLAB Function块输出至Display块
    
 add_line(modelName, [modelName '/AnomalyDetection/1'], [modelName '/AlertStatus/1']);

 % 添加To File块保存健康数据

    
 add_block('simulink/Sinks/To File', [modelName '/SaveHealthData']);
    
 set_param([modelName '/SaveHealthData'], 'VariableName', 'healthDataLog');
    
 set_param([modelName '/SaveHealthData'], 'SaveFormat', 'Array');

 set_param(modelName, 'StopTime', '3600'); % 设置停止时间为3600秒，即1小时

    
 set_param(modelName, 'Solver', 'ode45'); % 使用默认求解器

 add_block('simulink/Sinks/Scope', [modelName '/HealthData']);

    
 add_block('simulink/Sinks/Scope', [modelName '/AlertSignal']);
