这个错误通常是由于在多进程环境中使用了不支持共享的对象或属性导致的。`AttributeError: 'ForkAwareLocal' object has no attribute 'connection'` 错误表明在创建 `com_dict` 属性时出现了问题。

在你的代码中，你正在尝试在 `detection_status` 方法中给 `com_dict` 添加属性 `a`，但在多进程环境中，不能直接在命名空间对象上动态添加属性，因为它不是共享的。

要解决这个问题，你可以使用 `manager.dict()` 来创建一个共享的字典对象，然后在 `detection_status` 方法中使用该字典对象来添加属性。以下是修正后的示例代码：

from multiprocessing import Process, Manager, Pipe

class MonitoringProcess:
    def __init__(self):
        self.conn1, self.conn2 = Pipe()
        self.monitor = True
        self.process_start(self.detection_status)

    def set_monitor(self):
        self.com_dict["monitor"] = False

    def process_start(self, func):
        with Manager() as manager:
            self.com_dict = manager.dict()
            p = Process(target=func, args=(self.com_dict,))
            p.start()

    def detection_status(self, com_dict):
        # some code ...
        com_dict["a"] = 1

在修正后的代码中，我们使用 `manager.dict()` 创建了一个共享的字典对象 `com_dict`。然后，在 `detection_status` 方法中，我们使用 `com_dict["a"] = 1` 的方式向字典中添加属性。
