好的,这里是一份简单的Halm功率测试仪与自动化设备UDP通讯的DEMO代码,希望能对您有所帮助。
```python
import socket
import struct
# 定义UDP通讯参数
UDP_IP = "192.168.0.1" # 自动化设备IP地址
UDP_PORT = 5005 # 自动化设备接收数据的端口号
# 创建UDP通讯对象
sock = socket.socket(socket.AF_INET, # Internet
socket.SOCK_DGRAM) # UDP
# 发送指令给自动化设备
cmd = b'\x01\x02\x03\x04' # 指令码
data = struct.pack('4s', cmd) # 打包指令数据
sock.sendto(data, (UDP_IP, UDP_PORT))
# 接收自动化设备发来的数据
while True:
data, addr = sock.recvfrom(1024) # 一次最多接收1024字节的数据
if data:
# 解析数据
result = struct.unpack('f', data) # 解包数据
print('收到自动化设备发来的数据:', result[0])
break
# 关闭UDP通讯对象
sock.close()
```
以上代码仅供参考,具体实现需要根据您的具体需求进行修改。

c#自动化与光伏太阳能IV测试仪HALM软件的UDP通讯的示例代码
以下是一个简单的 C# 示例代码,用于与光伏太阳能 IV 测试仪 HALM 软件进行 UDP 通信:
```csharp
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace HalmUdpExample
{
class Program
{
static void Main(string[] args)
{
// 设置 HALM 软件的 IP 和端口号
string halmIp = "192.168.0.100";
int halmPort = 3000;
// 创建 UDP 客户端对象
UdpClient client = new UdpClient();
// 设置客户端发送数据的 IP 和端口号
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse(halmIp), halmPort);
// 准备要发送的数据
string data = "Test data";
byte[] bytes = Encoding.ASCII.GetBytes(data);
// 发送数据
client.Send(bytes, bytes.Length, endPoint);
// 接收数据
byte[] receiveBytes = client.Receive(ref endPoint);
string receiveData = Encoding.ASCII.GetString(receiveBytes);
// 输出接收到的数据
Console.WriteLine($"Received: {receiveData}");
// 关闭客户端
client.Close();
}
}
}
```
在此示例中,我们首先设置 HALM 软件的 IP 地址和端口号,然后创建一个 UDP 客户端对象,并将要发送的数据转换为字节数组。接下来,我们使用客户端对象的 `Send()` 方法向 HALM 软件发送数据。然后,我们使用客户端对象的 `Receive()` 方法接收从 HALM 软件返回的数据,并将其转换为字符串格式,最后输出接收到的数据。
请注意,此示例仅用于演示如何与 HALM 软件进行 UDP 通信,并不能直接用于实际的自动化测试。实际应用中,您需要根据具体的测试需求编写更加复杂和完整的代码。
Example of protocol with TRG-STA-GRS command cycle The initialization and reconnection of the communication is described in the chapter before. In order to initialize the communication, the MS toggles the Sync flag between 0 and 1 with cycle duration of 500 ms. Once the SC recognizes the Sync flag, it answers with an ACK frame of the same value as the detected Sync flag. The command STA is set to 2 (STA(02)) by the SC to request continuous status information. Hereupon, the MS sends its state with every answer. A prerequisite to accept commands by the MS is STA(01) (reply code from halm MS) and TOK(01). Direction Command code Reply Code Flag Remark SC → MS STA(02),TRG(01) Trigger a measurement * MS → SC Handshake acknowledge MS → SC STA(01), TRG(01) Trigger accepted SC → MS Handshake acknowledge SC → MS STA(02), TRG(FF) Command completed MS → SC Handshake acknowledge MS → SC TRG(FF), STA(02) TOK(FF) Reply completed, MS busy, cell transport not allowed SC → MS Handshake acknowledge MS → SC STA(02) TOK(01) Cell transport allowed SC → MS Handshake acknowledge MS → SC STA(01) RES(01) Measurement result data available SC → MS Handshake acknowledge SC → MS STA(02), GRS(01) MS → SC Handshake acknowledge MS → SC STA(01), GRS(01) RES(FF) Including result data SC → MS Handshake acknowledge SC → MS STA(02), GRS(FF) Command completed MS → SC Handshake acknowledge MS → SC STA(01), GRS(FF) Reply completed SC → MS Handshake acknowledge * SC sends TWO commands within one frame. In consequence, MS will reply with TWO answers. Same procedure for THREE commands. Please always send STA(02) together with every command. Do not send STA(FF) which will stop MS sending status and results.根据这个协议,帮我写一份UDP通讯的demo
好的,这里是一份简单的基于UDP通讯的TRG-STA-GRS命令循环协议的demo,希望能对您有所帮助。
```python
import socket
import struct
import time
# 定义UDP通讯参数
UDP_IP = "192.168.0.1" # MS设备IP地址
UDP_PORT = 5005 # MS设备接收数据的端口号
# 创建UDP通讯对象
sock = socket.socket(socket.AF_INET, # Internet
socket.SOCK_DGRAM) # UDP
# 初始化通讯:MS设备发送Sync flag,SC设备返回ACK
for i in range(2):
sync_flag = i % 2 # Sync flag为0或1
data = struct.pack('B', sync_flag) # 打包Sync flag数据
sock.sendto(data, (UDP_IP, UDP_PORT))
print('发送Sync flag:', sync_flag)
time.sleep(0.5) # 延时500ms
data, addr = sock.recvfrom(1024) # 接收ACK
ack_flag = struct.unpack('B', data)[0] # 解包ACK flag数据
print('收到ACK flag:', ack_flag)
# 发送TRG-STA-GRS命令循环
while True:
# 命令1:TRG(01), STA(02)
cmd1 = b'\x01\x02' # TRG(01), STA(02)
data = struct.pack('2s', cmd1) # 打包命令1数据
sock.sendto(data, (UDP_IP, UDP_PORT))
print('发送命令1:TRG(01), STA(02)')
data, addr = sock.recvfrom(1024) # 接收回复
reply1 = struct.unpack('2B', data) # 解包命令1的回复数据
print('收到命令1的回复:', reply1)
# 命令2:TRG(FF), STA(02)
cmd2 = b'\xFF\x02' # TRG(FF), STA(02)
data = struct.pack('2s', cmd2) # 打包命令2数据
sock.sendto(data, (UDP_IP, UDP_PORT))
print('发送命令2:TRG(FF), STA(02)')
data, addr = sock.recvfrom(1024) # 接收回复
reply2 = struct.unpack('2B', data) # 解包命令2的回复数据
print('收到命令2的回复:', reply2)
# 命令3:GRS(01), STA(02)
cmd3 = b'\x02\x01' # GRS(01), STA(02)
data = struct.pack('2s', cmd3) # 打包命令3数据
sock.sendto(data, (UDP_IP, UDP_PORT))
print('发送命令3:GRS(01), STA(02)')
data, addr = sock.recvfrom(1024) # 接收回复
reply3 = struct.unpack('2B', data) # 解包命令3的回复数据
print('收到命令3的回复:', reply3)
# 判断是否需要继续命令循环
if reply2[1] == 0xFF: # 如果命令2回复为TRG(FF), STA(02),则退出循环
break
# 关闭UDP通讯对象
sock.close()
```
以上代码仅供参考,具体实现需要根据您的具体需求进行修改。注意,这里的demo仅实现了命令循环的基本功能,如果需要实现更多的功能,还需要根据协议进行相应的扩展。
