说明：  ZCL是Zigbee1.1（Zigbee2006）协议版本中增加的一个重要的部分。在Zigbee中，一个簇群就是一个容器，在容器中以命令结构体包含了一个或多个属于某个应用剖面的属性/消息，不管应用剖面如何，相同的设备（比如开关）拥有相同的定义和功能。属性是设备的变量或特性，能够设置或获得。比如设置自动调温器的加热点。ZCL提供了一种机制，利用这种机制设备能够将变化异步地报告给属性（attribute），比如当空气变热时自动控温器服务器就将室温改变报告给他的客户端，这个过程不需要客户端发起请求
(ZCL is an important part of the Zigbee1.1 (Zigbee2006) protocol version. In the ZigBee, a cluster is a container, in the container to command structure contains one or more belongs to the properties of an application profile/message, regardless of the application profile, the same equipment (such as switches) have the same definition and function. Property is the variable or characteristic of a device, capable of setting or. For example, set the automatic thermostat heating point. ZCL provides a mechanism, the mechanism device can change asynchronously report to attribute, such as when the air becomes hot when the automatic temperature control of the server will be room temperature change report to his client, this process does not require the client initiates a request)
