env_recv不见了
线程初始化函数
```c
result1 = rt_thread_init(&env_send_thread,
                            "env_send",
                            env_send,
                            RT_NULL,
                            &env_send_stack[0],
                            sizeof(env_send_stack),
                            19,
                            50);
    if (result1 == RT_EOK) 
	{
        rt_thread_startup(&env_send_thread);
    }
//接收线程	
	result2 = rt_thread_init(&env_recv_thread,
                            "env_recv",
                            env_recv,
                            RT_NULL,

                            18,
                            50);
    if (result2 == RT_EOK) 
	{
        rt_thread_startup(&env_recv_thread);
    }
```

```c

    result = rt_thread_init(&sc_fresh_thread,
