编写一个标签模式来覆盖包含动名词的名词短语,例如,the/DT receiving/VBG end/NN, assistant/NN managing/VBG editor/NN。 将这些模式添加到语法中,每行一个。使用您自己设计的一些标记句子来测试您的工作。

以下是覆盖包含动名词的名词短语的标签模式:
```
NP: {<DT>?<VBG>*<NN>}
```
这个模式匹配的名词短语中,可以有一个可选的限定词(DT),后面跟着任意数量的动名词(VBG),最后是一个名词(NN)。
以下是一些用于测试的标记句子:
1. The receiving end is responsible for processing incoming data.
```
The/DT receiving/VBG end/NN is/VBZ responsible/JJ for/IN processing/VBG incoming/JJ data/NNS ./.
```
2. The managing editor is responsible for overseeing the publication process.
```
The/DT managing/VBG editor/NN is/VBZ responsible/JJ for/IN overseeing/VBG the/DT publication/NN process/NN ./.
```
3. The cooking show features a celebrity chef preparing a gourmet meal.
```
The/DT cooking/VBG show/NN features/VBZ a/DT celebrity/NN chef/NN preparing/VBG a/DT gourmet/JJ meal/NN ./.
```

<modbus/modbus.h>,实现一个从站,接收主站的请求他,用C++实现,提供例子
当使用 C++ 实现 Modbus 从站时,您可以使用 C++ 的库来简化编码过程。以下是一个基本的示例代码,演示了如何使用 libmodbus 库来实现一个 Modbus TCP 从站,接收主站的请求。
```cpp
#include <iostream>
#include <modbus/modbus.h>
int main() {
modbus_t* ctx = nullptr;
ctx = modbus_new_tcp("127.0.0.1", 502); // 创建 Modbus TCP 从站实例
modbus_set_slave(ctx, 1); // 设置从站地址为1
if (modbus_connect(ctx) == -1) { // 连接到主站
std::cerr << "Failed to connect to the Modbus master." << std::endl;
modbus_free(ctx);
return -1;
}
uint8_t query[MODBUS_TCP_MAX_ADU_LENGTH]; // 查询缓冲区
int rc;
while (true) {
rc = modbus_receive(ctx, query); // 接收主站请求
if (rc == -1) {
std::cerr << "Error in receiving Modbus request." << std::endl;
break;
}
// 处理请求
uint8_t function_code = query[MODBUS_TCP_FUNC_OFF];
switch (function_code) {
case MODBUS_FC_READ_HOLDING_REGISTERS:
// 处理读取保持寄存器的请求
break;
case MODBUS_FC_WRITE_SINGLE_REGISTER:
// 处理写入单个寄存器的请求
break;
// 其他功能码的处理...
default:
std::cerr << "Unsupported function code: " << int(function_code) << std::endl;
break;
}
rc = modbus_reply(ctx, query, rc, ctx); // 发送响应
if (rc == -1) {
std::cerr << "Failed to send Modbus response." << std::endl;
break;
}
}
modbus_close(ctx); // 关闭连接
modbus_free(ctx); // 释放从站实例内存
return 0;
}
```
这个示例代码使用了 libmodbus 库来创建 Modbus TCP 从站实例,并处理了读取保持寄存器和写入单个寄存器的请求。您可以根据自己的需求进行扩展和修改。请确保已经安装了 libmodbus 库,并在编译时链接该库。
希望这个示例对您有所帮助!
Install/Remove of the Service Denied!
If you are receiving an "Install/Remove of the Service Denied" error message, it is likely that you do not have the necessary permissions to install or remove the service.
To resolve this issue, you will need to log in to your computer with an account that has administrative privileges. If you are already logged in with an administrative account, try right-clicking on the installation file or the service and selecting "Run as administrator."
If the issue persists, it may be necessary to contact your system administrator for assistance.
