ISO18000-6C协议UHF6C超高频RFID读写C#源码

news 2025/10/26 17:47:37

UHF6C超高频标签一般分为四个独立的存储区：保留区、EPC区、TID区、用户区；
保留区：8个字节，前4个字节为摧毁密码（通常不使用），后4个字节为访问密码（用于写入数据和锁定操作），默认值为：00 00 00 00（摧毁密码）00 00 00 00（访问密码）；
TID区：12字节，只可读不可写，出厂时已写入，为标签的唯一标识符和电子标签的产品类别识别号；
EPC区：用于识别标签对象的电子产品码，EPC与TID不同，用户可手动写入修改。EPC数据结构中，第一个字为校验位，第二个字为长度控制，之后为数据存储位置。在盘点时，根据长度控制位显示EPC长度。实际写入时，起始地址为1，校验位自动计算，无需手动填写；
用户区：存储长度由各电子标签生产商确定，用户可在此区域写入自定义数据，注意有的标签此区大小为0字节。

二、单次寻卡并返回EPC

private void button3_Click(object sender, EventArgs e)
{listBox1.Items.Clear();textBox3.Text = "";uhfg2infobufclear();byte status = uhfg2inventory();byte[] rssi = new byte[1];byte[] pc = new byte[2];byte[] epcbuf = new byte[12];Double i = 0;Double mw;if (status == 0){do {status = uhfg2infobufget(rssi, pc, epcbuf);if (status == 0 || status == 1){if (rssi[0] < 128){i = rssi[0];}else { i = -1 - (rssi[0] ^ 255); }mw = Math.Pow(10, (i / 10));string dispstr = "RSSI:" + rssi[0].ToString("X02") + " 等于输入信号强度:" + i.ToString() + "dBm(" + string.Format("{0:0.000000000}", mw) + "mW),信号路径损耗补偿值PC:" + pc[1].ToString("X02") + pc[0].ToString("X02") + ",EPC:";string epcstr = "";for (int j = 0; j < 12; j++){epcstr = epcstr + epcbuf[j].ToString("X02") + " ";dispstr = dispstr + epcbuf[j].ToString("X02");}textBox3.Text = dispstr;listBox1.Items.Add(dispstr);if (comboBox4.SelectedIndex == 1) { textBox4.Text = epcstr; }}}while (status==1);MessageBox.Show("寻卡成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{MessageDispInfo(status);}
}

三、连续寻卡并返回EPC

private void button5_Click(object sender, EventArgs e)
{if (button5.Text == "连续寻卡  (用于大量卡同时感应)"){                listBox1.Items.Clear();textBox3.Text = "";uhfg2infobufclear();byte status = uhfg2inventorystart();if (status == 0 || status == 8){button5.Text = "停止连续寻卡";                    timer1.Enabled = true;button3.Enabled = false;button6.Enabled = false;button7.Enabled = false;button9.Enabled = false;button10.Enabled = false;button11.Enabled = false;button12.Enabled = false;}}else{timer1.Enabled = false;byte status = uhfg2inventorystop();button5.Text = "连续寻卡  (用于大量卡同时感应)";button3.Enabled = true;button6.Enabled = true;button7.Enabled = true;button9.Enabled = true;button10.Enabled = true;button11.Enabled = true;button12.Enabled = true;}
}private void timer1_Tick(object sender, EventArgs e)
{byte[] rssi = new byte[1];byte[] pc = new byte[2];byte[] epcbuf = new byte[12];byte status;Double i = 0;Double mw;do{System.Windows.Forms.Application.DoEvents();status = uhfg2infobufget(rssi, pc, epcbuf);     //从读卡器缓冲中读出卡号if (status == 0 || status == 1){pcdbeep(20);if (rssi[0] < 128){i = rssi[0];}else { i = -1 - (rssi[0] ^ 255); }mw = Math.Pow(10, (i / 10));string dispstr = "RSSI:" + rssi[0].ToString("X02") + " 等于输入信号强度:" + i.ToString() + "dBm(" + string.Format("{0:0.000000000}", mw) + "mW),信号路径损耗补偿值PC:" + pc[1].ToString("X02") + pc[0].ToString("X02") + ",EPC:";string epcstr = "";for (int j = 0; j < 12; j++){epcstr = epcstr + epcbuf[j].ToString("X02");}dispstr = dispstr + epcstr;textBox3.Text = dispstr;bool addlist = true;if (listBox1.Items.Count > 0){for (int j = 0; j < listBox1.Items.Count; j++){string liststr = listBox1.Items[j].ToString().Trim();if (liststr.Substring(liststr.Length - 24, 24) == epcstr){addlist = false;}}}if (addlist) { listBox1.Items.Add(dispstr); }}}while (status == 1);
}

四、读取卡内数据

private void button9_Click(object sender, EventArgs e)
{byte[] accesspwd = new byte[4];if (checkhexstr(textBox5.Text.Trim(), 4, accesspwd) == false){MessageBox.Show("十六进制认证密钥输入错误，请输入 4 字节16进制认证密钥！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error);textBox5.Select();return;}byte wordlen = (byte)numericUpDown_wordlen.Value;if(wordlen>16){MessageBox.Show("长度不能大于16个字！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error);numericUpDown_wordlen.Select();return;}byte wordaddr = (byte)numericUpDown_wordaddr.Value;byte[] pc = new byte[2];byte[] epcbuf = new byte[12];byte[] piccdata = new byte[32];byte status = uhfg2read(accesspwd,(byte)comboBox7.SelectedIndex, wordaddr, wordlen, pc, epcbuf, piccdata);if (status == 0 || status == 12 || status == 13){textBox7.Text = pc[1].ToString("X02") + pc[0].ToString("X02");string epcstr = "";for (int j = 0; j < 12; j++) {epcstr = epcstr + epcbuf[j].ToString("X02")+" ";}textBox8.Text = epcstr;if (status == 0) {string datastr = "";for (int j = 0; j < wordlen*2; j++){datastr = datastr + piccdata[j].ToString("X02") + " ";}textBox6.Text = datastr;MessageBox.Show("读卡成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{MessageDispInfo(status);}}else{MessageDispInfo(status);}
}

五、写数据到卡内

private void button10_Click(object sender, EventArgs e)
{byte[] accesspwd = new byte[4];if (checkhexstr(textBox5.Text.Trim(), 4, accesspwd) == false){MessageBox.Show("十六进制认证密钥输入错误，请输入 4 字节16进制认证密钥！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error);textBox5.Select();return;}byte wordlen = (byte)numericUpDown_wordlen.Value;if (wordlen > 16){MessageBox.Show("长度不能大于16个字！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error);numericUpDown_wordlen.Select();return;}byte[] piccdata = new byte[32];if (checkhexstr(textBox6.Text.Trim(), wordlen * 2, piccdata) == false){MessageBox.Show("十六进制写入数据输入错误，请输入"+ (wordlen*2).ToString() +" 字节16进制写卡数据！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error);textBox6.Select();return;}byte wordaddr = (byte)numericUpDown_wordaddr.Value;byte[] pc = new byte[2];byte[] epcbuf = new byte[12];byte status = uhfg2write(accesspwd, (byte)comboBox7.SelectedIndex, wordaddr, wordlen, pc, epcbuf, piccdata);if (status == 0 || status == 12 || status == 14){textBox7.Text = pc[1].ToString("X02") + pc[0].ToString("X02");string epcstr = "";for (int j = 0; j < 12; j++){epcstr = epcstr + epcbuf[j].ToString("X02") + " ";}textBox8.Text = epcstr;if (status == 0){MessageBox.Show("写卡成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{MessageDispInfo(status);}}else{MessageDispInfo(status);}
}
