Android 串口开发——定时查询心跳数据，解析心跳数据。——持续更新中

/**
 * 字节数组转换成对应的16进制表示的字符串
 *
 * @param src
 * @return
 */
public static String bytes2HexStr(byte[] src) {
    StringBuilder builder = new StringBuilder();
    if (src == null || src.length <= 0) {
        return "";
    }
    char[] buffer = new char[2];
    for (int i = 0; i < src.length; i++) {
        buffer[0] = Character.forDigit((src[i] >>> 4) & 0x0F, 16);
        buffer[1] = Character.forDigit(src[i] & 0x0F, 16);
        builder.append(buffer);
    }
    return builder.toString().toUpperCase();
}

 1、心跳数据强转为 byte[] 数据类型

@Override
public RecvCommand adaptReceive(byte[] allPack, Object... other) {
    int cmd = (int) other[0];
    LogPlus.e( "收到的命令:" +cmd);
    byte[] data = (byte[]) other[1];

 

2、开始解析——必须根据解析协议才能解析数据

public class RecvA3Status extends BaseRecvCommand {

    private final int mResult;

    private final float mPowerFactorState;
    public List auxiliaryPlates;

    public RecvA3Status(byte[] allPack, byte[] data) {
        super(allPack, data);
        mResult = 0xff & data[0];

        mPowerFactorState = ByteUtil.getFloat(data, 25);

        auxiliaryPlates = new ArrayList<>();
        for (int i = 0; i < (data.length - 29) / 107; i++) {
            byte[] bytes = new byte[107];
            System.arraycopy(data, 29 + i * 107, bytes, 0, bytes.length);
            if (i==0){
                LogPlus.e("几号门==="+i, "门状态11接收数据2仓门=" + ByteUtil.bytes2HexStr(bytes));
            }else {
                LogPlus.i("几号门==="+i, "门状态11接收数据2仓门=" + ByteUtil.bytes2HexStr(bytes));

            }

            auxiliaryPlates.add(new AuxiliaryPlate(bytes));
        }
    }

    /**
     * 仓控板状态表
     */
    public static class AuxiliaryPlate {
        private int onlineState;
        private int doorState;
        private int batteryState;
        private int fireState;
        private int urgentState;
        private int temperature;
        private int batteryVoltage;
        private int chargerOnlineState;
        private ChargerState chargerState;
        private OnOffAmount onOffAmount;
        private AnalogQuantity analogQuantity;

        private int BMSOnlineState;
        private String BMSID;

        /**type 0 = 正常电池样式  1 = 显示屏样式 */
        public int type = 0;

        public AuxiliaryPlate(byte[] bytes) {
            onlineState = 0xff & bytes[0];
            doorState = 0xff & bytes[1];
            batteryState = 0xff & bytes[2];
            fireState = 0xff & bytes[3];
            urgentState = 0xff & bytes[4];
            temperature = 0xff & bytes[5];
            batteryVoltage = ByteUtil.bytes2long(bytes, 6, 2) / 100;
            chargerOnlineState = 0xff & bytes[8];

            byte[] bytes1 = new byte[6];
            System.arraycopy(bytes, 9, bytes1, 0, bytes1.length);
            chargerState = new ChargerState(bytes1);
            BMSOnlineState = 0xff & bytes[15];

            byte[] bytes2 = new byte[26];
            System.arraycopy(bytes, 16, bytes2, 0, bytes2.length);
            BMSID = new String(bytes2, StandardCharsets.US_ASCII).trim();

            byte[] bytes3 = new byte[7];
            System.arraycopy(bytes, 42, bytes3, 0, bytes3.length);
            onOffAmount = new OnOffAmount(bytes3);

            byte[] bytes4 = new byte[58];
            System.arraycopy(bytes, 49, bytes4, 0, bytes4.length);
            analogQuantity = new AnalogQuantity(bytes4);
        }
