【问题描述】：

我一直试图通过串行端口（Prolific USB-to-Serial Comm Port）读取温度/湿度监测设备，但我得到的值不是我所期望的。可能是我去错了地方。

这是我到目前为止所尝试的。

端口设置：

PortName:Com1
BaudRate: 38400
DataBits: 8
DiscardNull:False
DtsEnable:False
GenerateMember: True
Handshake: None
Parity: None
ParityReplace:63
ReadBuffersize:4096
ReadTimeout: -1
ReceivedBytesThreshold:1
RtsEnable: False
StopBits:One
WriteBufferSize: 2048
WriteTimeout:-1

private void SerialPortTH_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
    try
    {
        if (rtxMsg.InvokeRequired)
        {
            rtxMsg.Invoke(new MethodInvoker(delegate {
                //this is my work
                int bufferToRead = SerialPortTH.BytesToRead;
                buffer = new byte[bufferToRead];
                SerialPortTH.Read(buffer, 0, bufferToRead);
                rtxMsg.Text += BitConverter.ToString(buffer);
                rtxMsg.Text += Environment.NewLine;
            using (System.IO.StreamWriter file = new System.IO.StreamWriter("incomingData.txt", true))
            {
                file.WriteLine(rtxMsg.Text);
            }
        }));
        }
    }
    catch (Exception ex)
    {
        if (lblException.InvokeRequired)
        {
            lblException.Invoke(new MethodInvoker(delegate {
                lblException.Text += ex.Message + Environment.NewLine;
            }));
        }
    }
}

这就是我得到的：

【问题讨论】：

确保两个串口速度一致
请看我的编辑问题，我已经添加了我的串口设置。
这里没有两个串口..只有一个端口只是读取设备。
设备也有串口，有特定的速度。能贴出_温湿度监测设备_的具体名称吗？
无论您从设备获得什么，它都不是 ASCII。你能从众多中分辨出来吗？问号，这是一个无法转换的字节。也许波特率是错误的，38400 是一个非常不寻常的选择。也许设备发送二进制数据而不是文本。您必须使用 RTFM 或使用电话。

标签： c# .net serial-port

【解决方案1】：

这就是我计算值的方式。首先从传入数据中删除破折号并将读取速度减慢 150 毫秒。线程.sleep(150)。

System.Threading.Thread.Sleep(150);
int buffToRead = serialPort1.BytesToRead;
byte[] buffer = new byte[buffToRead];
serialPort1.Read(buffer, 0, buffToRead);
string rStream = BitConverter.ToString(buffer).Replace("-", "");

这会给你：

0144F100B501E114AD44A101476600FC00F3DA6738E4676100C060FE3F37

我总是检查值是否大于 50 并以 0144 开头。这给了我准确的结果。在这 0144 之后的第一个十六进制值

F1 = Hex to Dec 241/10 = 24.10

温度为 24.10 摄氏度，第二个值 00B5 我已将 00 转换为 1 = 1B5

1B5 = Hex To Dec = 437/10 = 43.7 Humidity.

您还需要做其他事情，例如 CRC 校验和，以确保数据始终正确。
