我目前正在制定ASTM协议，向医疗器械发送订单测试请求。但是我无法正确地向设备发送消息。为了更明确，我想要例如发送这些帧：

        String h1, s2, s3, s4, s5, s6 = "";
        h1 = "H|@^\\|ODM-IdfDGIWA-36|||GeneXpert PC^GeneXpert^4.8|||||LIS||P|1394-97|20070521100245";
        s2 = "P|1";
        s3 = "O|1|SID-818||^^^TestId-12|S|20070812140500|||||A||||ORH||||||||||Q";
        s4 = "O|2|SID-818||^^^TestId-14|S|20070812140600|||||A||||ORH||||||||||Q";
        s5 = "O|3|SID-818||^^^TestId-16|S|20070812140700|||||A||||ORH||||||||||Q";
        s6 = "L|1|F";

以下是我现在的表现：

    writeMeBytes(outToServer, h1.getBytes());
    writeMeBytes(outToServer, s2.getBytes());
    writeMeBytes(outToServer, s3.getBytes());
    writeMeBytes(outToServer, s4.getBytes());
    writeMeBytes(outToServer, s5.getBytes());
    writeMeBytes(outToServer, s6.getBytes());


public static void writeMeBytes(DataOutputStream dos, byte [] b){
    if (b.length >0){
        int j = 0;
        while (j <= b.length-1) {
            try {
                dos.write(b[j++]);
            } catch (IOException ex) {
                Logger.getLogger(SimpleServer.class.getName()).log(Level.SEVERE, null, ex);
            }

        }
    }
}

我将其转换为字节，然后逐字节发送。

除了接收方没有看到任何变化外。

根据@Muhammad答案更新

这就是我向GeneXpert DX系统发送订单所做的工作

public class SimpleServer {

private static ServerSocket server;
private static Socket connection;

public static void main(String args[]) throws IOException, InterruptedException {
    server = new ServerSocket(12221);
    boolean stopped = false;

    System.out.println(" start... ");
    connection = server.accept();
    System.out.println("wait for connection");
    BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    DataOutputStream outToClient = new DataOutputStream(connection.getOutputStream());
    String currentMsg = "";
    int clientIntMessage;

    String h1, s2, s3, s4, s5, s6 = "";
    h1 = "1H|@^\\|ODM-IdfDGIWA-36|||GeneXpert PC^GeneXpert^4.8|||||LIS||P|1394-97|20070521100245" + ProtocolASCII.LF
            + "P|1" + ProtocolASCII.LF
            + "O|1|SID-818||^^^TestId-12|S|20070812140500|||||A||||ORH||||||||||Q" + ProtocolASCII.LF
            + "L|1|F" + ProtocolASCII.LF;
    s2 = "P|1";
    s3 = "O|1|SID-818||^^^TestId-12|S|20070812140500|||||A||||ORH||||||||||Q";
    //s4 = "O|2|SID-818||^^^TestId-14|S|20070812140600|||||A||||ORH||||||||||Q";
    //s5 = "O|3|SID-818||^^^TestId-16|S|20070812140700|||||A||||ORH||||||||||Q";
    s6 = "L|1|F";

    String retmsg = h1;
    //logException("OrderMessae   :" + retmsg);
    retmsg = ProtocolASCII.STX + retmsg + ProtocolASCII.CR + ProtocolASCII.ETX + ProtocolMessage.getCheckSum(retmsg) + ProtocolASCII.CR + ProtocolASCII.LF;

    clientIntMessage = inFromClient.read();
    //while (clientIntMessage != ProtocolASCII.EOT) {
    while (true) {
        currentMsg += String.valueOf(Character.toChars(clientIntMessage));
        if (clientIntMessage == ProtocolASCII.ENQ) {
            outToClient.writeBytes("" + ProtocolASCII.ACK);
            System.out.println(" <--- LIS [ACK] on DX [ENQ]");
        } else if (clientIntMessage == ProtocolASCII.ACK) {
            System.out.println(" ---> DX [ACK]");
            // Send your order message here
            outToClient.writeBytes(retmsg);
        } else if (clientIntMessage == ProtocolASCII.CR) {
            System.out.println(currentMsg);
            outToClient.writeBytes("" + ProtocolASCII.ACK);
        } else if (clientIntMessage == ProtocolASCII.NAK) {
            System.out.println(" ---> DX sent [NAK] ");
            System.out.println(" --- LIS now wait 10 sec... ");
            Thread.sleep(10000);
            outToClient.writeBytes("" + ProtocolASCII.ENQ);
            System.out.println(" <--- LIS [ENQ] ");
        } else if (clientIntMessage == ProtocolASCII.EOT) {
            System.out.println(" ---> DX END OF TRANSMISSION");
            outToClient.writeBytes("" + ProtocolASCII.ENQ);
            System.out.println(" <--- LIS [ENQ] ");
        }

        if (stopped) {
            break;
        }
        clientIntMessage = inFromClient.read();
    }
    connection.close();
    stopped = true;
}}

这是我从控制台得到的结果：

start... 
wait for connection
 <--- LIS [ACK] on DX [ENQ]
1H|@^\|ODM-rQTcjIWA-66||GeneXpert PC^GeneXpert^4.8|||||LIS||P|1394-97|20180314003724
Q|1|ALL||||||||||O@N
L|1|N
B5
 ---> DX [EOT] 
 <--- LIS [ENQ] 
 ---> DX [ACK]
 ---> DX sent [NAK] 
 --- LIS now wait 10 sec...

DX是机器软件，LIS是主机。 每当我尝试发送ENQ时，机器都会用NAK回答我。

它似乎工作。但是现在Windows事件向我显示了一个错误，为什么我的记录命令没有出现在GeneXpert DX主机记录列表中。标题记录已首先发送。

答案 0 :(得分：3)

在回答之前，让我们讨论双向的机制。

String h1, s2, s3, s4, s5, s6 = "";
    h1 = "H|@^\\|ODM-IdfDGIWA-36|||GeneXpert PC^GeneXpert^4.8|||||LIS||P|1394-97|20070521100245";
    s2 = "P|1";
    s3 = "O|1|SID-818||^^^TestId-12|S|20070812140500|||||A||||ORH||||||||||Q";
    s4 = "O|2|SID-818||^^^TestId-14|S|20070812140600|||||A||||ORH||||||||||Q";
    s5 = "O|3|SID-818||^^^TestId-16|S|20070812140700|||||A||||ORH||||||||||Q";
    s6 = "L|1|F";

首先，查看上面的字符串消息，没有任何标记编号，因为到目前为止我所做的每台计算机都需要标记号。例如：

1H|\^&|||CS-2500^00-08^22029^^^CP^BV981798||||||||E1394-97
2P|1|||00000152556|^JOHN^ABC||19440601|M|||||^Dr.Shaukat Khanum Hospital|||||||||^^^EAST
3O|1|000038^01^0012586236^B||^^^051^^100.00¥^^^044^^100.00|R|201803081225236|||||N
4L|1|N

因此，每个代码必须包含 NUMBERING 。

第二次，机器首次发送以下查询：

1H|\^&|||CS-2500^^22029^^^CP^BV981798||||||||E1394-9711
2Q|1|000038^01^   0012365845B||^^^040^PT-INN\^^^050^APTT-FS|0|201803081227007F
3L|1|NF9

在，查询（2Q）标记，000038机架ID，01机架序列号，001H18074618样本ID（从条形码读取），可以从主机或LIS验证更多信息机器供应商提供的手册。

第三次，当我们收到此消息时，我们会为上面描述的机器（下面再次写入）提供其他校验和信息。同样，这个校验和可以在机器的主机或LIS手册中找到。

1H|\^&|||CS-2500^00-08^22029^^^CP^BV981798||||||||E1394-97
2P|1|||00000152556|^JOHN^ABC||19440601|M|||||^Dr.Shaukat Khanum Hospital|||||||||^^^EAST
3O|1|000038^01^12345678^B||^^^051^^100.00¥^^^044^^100.00|R|201803081225236|||||N
4L|1|N

校验和计算示例。请注意，它可能因机器而异。 

  public static String getCheckSum(String msg) {
    int sum = 0;
    for (int i = 0; i < msg.length(); i++) {
        sum += msg.charAt(i);
    }
    sum += 16; //adding CR and ETX AND ETB
    sum = sum % 256;
    String checksum = Integer.toHexString(sum).toUpperCase();
    if (checksum.length() == 1) {
        checksum = "0" + checksum;
    }
    //System.out.println("\n Check Sum is ="+checksum);
    return checksum;
}

这是我们发送给机器的完整信息：

String retmsg = "3O|1|" + rackId + "^" + positionNumber + "^" + sampleId + "^B||" + testIds + "|" + priority + "|" + sysDate + "|||||" + orderType + "";
    logException("OrderMessae   :" + retmsg);
    retmsg = ProtocolASCII.STX + retmsg + ProtocolASCII.CR + ProtocolASCII.ETX + ProtocolMessage.getCheckSum(retmsg) + ProtocolASCII.CR + ProtocolASCII.LF;

最后但并非最不重要，我不知道机器是什么，因为我没有手册，但我觉得你不需要逐个发送每条消息。您可以一次发送所有内容。

这是发送和接收来自机器的消息的代码片段。

while (clientIntMessage != ProtocolASCII.EOT) {
                    clientIntMessage = inFromClient.read();
                    currentMsg += String.valueOf(Character.toChars(clientIntMessage));
                    // System.out.println(currentMsg);
                    if (clientIntMessage == ProtocolASCII.ENQ) {
                        outToClient.writeBytes("" + ProtocolASCII.ACK);
                        System.out.println("[ACK] on Analyzer [ENQ]");
                    } else if (clientIntMessage == ProtocolASCII.ACK) {                        
                        System.out.println("Analyzer [ACK]");
                        // Send your order message here
                         outToClient.writeBytes(retmsg);
                        }
                    } else if (clientIntMessage == ProtocolASCII.LF) {
                        outToClient.writeBytes("" + ProtocolASCII.ACK);
                    } else if (clientIntMessage == ProtocolASCII.NAK) {
                        System.out.println(" Analyzer sent [NAK] ");
                    }

                }

ProtocolASCII.ACK 为'\006'， ProtocolASCII.ENQ 为'\005'， ProtocolASCII.EOT 为{ {1}}。

代码几乎是自我解释的，我在生产中使用它。

您能告诉我们您正在连接哪台机器吗？如果我已经集成，它可能会有所帮助。

谢谢。如果需要进一步的帮助，请告诉我。

供您参考：

'\004'

<强>更新

来自您的评论：

public class ProtocolASCII { public static char STX = '\002'; public static char ETX = '\003'; public static char ETB = '\027'; public static char EOT = '\004'; public static char ENQ = '\005'; public static char ACK = '\006'; public static char NAK = '\025'; public static char CR = '\r'; public static char LF = '\n'; public static char MOR = '>'; public static char FS = '\034'; public static char GS = '\035'; public static char RS = '\036'; public static char SFS = '\027'; public static char VT = 0x0B; //END OF BLOCK 011 } 其中 testIds 是要执行的测试列表。

示例多重订单发送String retmsg = "3O|1|" + rackId + "^" + positionNumber + "^" + sampleId + "^B||" + testIds + "|" + priority + "|" + sysDate + "|||||" + orderType + "";

从LIS手册或公司工程师处获取测试代码并相应地制作模式。
