社区安防系统

项目名称：社区安防系统

设备：ADAM4150、烟雾传感器，火焰传感器，人体传感器、串口线

第三方库：新大陆公司的Analog4150库

实验现象：ADAM4150通过串口线连接到移动终端com6口。打开程序：当烟雾传感器检测到有烟雾时，界面提醒。当人体传感器检测到有人时会提醒。当火焰传感器检测到有火焰时，界面提醒同时出现火焰图片

步骤：

1、界面设计。在res/layout目录下的action_main.xml文件中进行修改。

2、新建一个BasePort.java调用新大陆提供的Analog4150库，实现串口打开和关闭功能。

import com.example.analoglib.Analog4150ServiceAPI;
public class BasePort {
    public int openADAMPort(int com,int mode,int baudRate){
        return Analog4150ServiceAPI.openPort(com, mode, baudRate);
    }
    public void closeADAMPort(){
        Analog4150ServiceAPI.closeUart();
    }
}

3、新建一个ADA4150.java文件，实现ADAM4150的控制功能和获取状态功能

import android.util.Log;
import com.example.analoglib.Analog4150ServiceAPI;
import com.example.analoglib.OnFireResponse;
import com.example.analoglib.OnPersonResponse;
import com.example.analoglib.OnSmorkResponse;
import com.example.analoglib.ReceiveThread;
public class ADAM4150 extends BasePort{
    //风扇开关命令，这些命名是根据协议的
    private final char[] open1Fan={0x01,0x05,0x00,0x10,0xFF,0x00,0x8D,0xFF};
    private final char[] close1Fan={0x01,0x05,0x00,0x10,0x00,0x00,0xCC,0x0F};
    private final char[] open2Fan={0x01,0x05,0x00,0x11,0xFF,0x00,0xDC,0x3F};
    private final char[] close2Fan={0x01,0x05,0x00,0x11,0x00,0x00,0x9D,0xCF};
    //创建ADAM4150类的构造方法，并实现人体、烟雾、火焰的实时取值，并用get方法返回
    public static int mADAM4150_fd=0;
    private boolean rePerson;
    private boolean reFire;
    private boolean reSmork;
    public ADAM4150(int com,int mode,int baudRate){
        //打开串口
        mADAM4150_fd=openADAMPort(com, mode, baudRate);
        ReceiveThread mReceiveThread=new ReceiveThread();
        mReceiveThread.start();
        //设置人体回调函数，人体传感器接入DI0
        Analog4150ServiceAPI.getPerson("person", new OnPersonResponse() {
            @Override
            public void onValue(boolean arg0) {
                rePerson=!arg0;
            }
            @Override
            public void onValue(String arg0) {
                Log.e("cjI",arg0);
            }
        });
        Analog4150ServiceAPI.getFire("fire", new OnFireResponse() {
            @Override
            public void onValue(boolean arg0) {
                reFire=!arg0;
            }
            @Override
            public void onValue(String arg0) {
                Log.e("cjI",arg0);
            }
        });
        Analog4150ServiceAPI.getSmork("Smork", new OnSmorkResponse() {
            @Override
            public void onValue(boolean arg0) {
                reSmork=!arg0;
            }
            @Override
            public void onValue(String arg0) {
                Log.e("cjI",arg0);
            }
        });
    }
    //获取传感器值，true或者false
    public boolean getPerson(){
        return rePerson;
    }
    public boolean getFire(){
        return reFire;
    }
    public boolean getSmork(){
        return reSmork;
    }
    //打开风扇
    public void openFan1(){
        Analog4150ServiceAPI.sendRelayControl(open1Fan);
    }
    public void openFan2(){
        Analog4150ServiceAPI.sendRelayControl(open2Fan);
    }
    public void closeFan1(){
        Analog4150ServiceAPI.sendRelayControl(close1Fan);
    }
    public void closeFan2(){
        Analog4150ServiceAPI.sendRelayControl(close2Fan);
    }
}

4、在MainActivity.java类中添加多线程逻辑控制界面的改变

import com.example.analoglib.Analog4150ServiceAPI;
import com.example.analoglib.AnalogHelper;
import com.example.analoglib.OnFireResponse;
import com.example.analoglib.OnPersonResponse;
import com.example.analoglib.OnReceiveCompleteListener;
import com.example.analoglib.OnSmorkResponse;
import com.example.analoglib.ReceiveThread;
import android.app.Activity;
import android.app.Service;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.Vibrator;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
import android.widget.ImageView;
public class MainActivity extends Activity {
    private TextView mTvFire;
    private TextView mTvPerson;
    private TextView mTvSmoke;
    private ImageView mImgFire;
    private ADAM4150 mAdam4150;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();//初始化控件
    }
    private void initView() {
        mTvFire = (TextView) findViewById(R.id.textView1);
        mTvPerson = (TextView) findViewById(R.id.textView3);
        mTvSmoke = (TextView) findViewById(R.id.textView2);
        mImgFire=(ImageView) findViewById(R.id.imageView2);
        //com6口，USB模式，9600波特率
        mAdam4150=new ADAM4150(6,1,3);
        mHandler.postDelayed(mRunnable,ms);
    }
    private int ms=1000;
    //声明一个Handler对象
    private Handler mHandler=new Handler();
    //声明一个Runnable对象
    private Runnable mRunnable=new Runnable() {
            @Override
            public void run() {
                mHandler.postDelayed(mRunnable,ms);
                mTvPerson.setText(mAdam4150.getPerson()?"无人":"有人");
                mTvFire.setText(mAdam4150.getFire()?"无火":"有火");
                mTvSmoke.setText(mAdam4150.getSmork()?"正常":"危险");
                //如果有火，显示火焰图片。否则就不显示火焰图片
                if(mAdam4150.getFire()){
                    mImgFire.setVisibility(View.GONE);
                }else{
                    mImgFire.setVisibility(View.VISIBLE);
               //     long ms=500;
              //      Vibrate(MainActivity.this,ms);
                }
                Analog4150ServiceAPI.send4150();
            }
        };
        //自定义Vibrate方法，调用系统自身的服务，实现震动功能
        public static void Vibrate(final Activity activity,long milliseconds){
            Vibrator vib=(Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
            vib.vibrate(milliseconds);
        }
}

5、这里要注意的是烟雾、火焰所接的ADAM4150口亮灭分别有和无，但是人体红外的亮灭是表示无有
