什么是电芯的直流内阻？下面两篇文章各位可以参考一下：
下面是IT8511表的测试指令，也可以使用字节流指令。
MEAS:CURR? SYST:REM 远程模式 MODE CURR 设置定电流模式 CURR 10 设置放电电流 MEAS:VOLT:DC? 读取电压值 INP 1 打开电子负载 MEAS:VOLT:DC? 读取电压值 INP 0 关闭电子负载 MEAS:CURR? 读取电流
这里勇哥放一个测试用的小程序，主要演示一下netMarketing的serialHelper类的用法。
using netMarketing.automation;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace comTest
{
public partial class Form1 : Form
{
serialHelper com1;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void openCom()
{
try
{
//参数第一个0无意义
com1 = new serialHelper(0, "这是com5口",
new serialHelper.SerialParamType()
{
PortName = "COM3",
PortBaudRate = 9600,
PortDataBits = 8,
PortParity = System.IO.Ports.Parity.None,
PortStopBits = System.IO.Ports.StopBits.One
});
com1.Write("SYST:REM\n");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void btnOpen_Click(object sender, EventArgs e)
{
openCom();
}
private void btnRead_Click(object sender, EventArgs e)
{
try
{
if (com1.IsOpen)
{
// btnRead.Enabled = false;
ThreadPool.QueueUserWorkItem(new WaitCallback(cmd));
}
}
catch { }
}
private void cmd(object m)
{
var buff11 = new StringBuilder();
var t11 = string.Empty;
var str11 = string.Empty;
var str22 = string.Empty;
int i = 0;
Stopwatch sw = new Stopwatch();
//设置放电电流大小
com1.Write("CURR 2\n");
//com1.Write("MEAS:VOLT?\r\n");
com1.Write("INP 1\n");
sw.Restart();
while (sw.ElapsedMilliseconds <= 200)
{
//Thread.Sleep(50);
com1.Write("MEAS:VOLT?\r\n");
Thread.Sleep(6);
}
try
{
// Thread.Sleep(10);
var f11 = com1.ReadExisting(out t11);
t11 = t11.Replace("\0", "");
var ary1 = t11.Split(new string[] { "\n" }, StringSplitOptions.RemoveEmptyEntries);
var list1 = ary1.ToList().ConvertAll((s) => double.Parse(s));
com1.clearComBuffer();
com1.Write("INP 0\n");
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
outmsg(rtbmsg, t11 + Environment.NewLine);
}
private void outmsg(RichTextBox box, string msg)
{
if (box.InvokeRequired)
{
box.Invoke(new Action(() =>
{
box.AppendText(msg);
}));
}
else
{
box.AppendText(msg);
}
}
private void button1_Click(object sender, EventArgs e)
{
rtbmsg.Text = null;
}
}
