工业物联网网关开源（开源物联网平台ThingsBoard之gateway网关配置空调控制实例）

近期，笔者发布了有关我们改造开源物联网平台Thingsborad的几篇文章，总体来讲CE版本还是很棒的，提供了物联网平台该有的基础能力。Thingsboard CE版本提供了Gateway网关能力，实现了物联平台和设备之间互联的功能。还是和往常一样，我们在研究的过程中，通过“物联网平台Thingsboard之Gateway使用实例”，尝试“接入bacnet/ip协议数据实现空调控制”，以此达到我们所改造平台和设备的协调一致。下面就将这个小小的使用示例或实例，分享给大家，感兴趣的朋友可以搭建平台并运行体验，或者私信联系我们体验。

Thingsboard gateway 目前只能接入bacnet/ip 协议的数据，非ip协议的bacnet的模块还不能直接接入；因此，在测试bacnet网关功能要主要购买带有bacnet/ip网关的产品；

采购的产品为海思Igate400网关和两个温控器，温控器与网关的通讯是走标准modbus RTU。

ip网关配置好网络后，可以得到ip地址和port端口； 例如：ip=192.168.254.88 port=47808

（1）调节前

（2）调节后

可以看出，通过温控器按钮调节温度是有了变化的。

时间仓促，也没写多少文字，只是大概写了几个实例的执行思路，通过这些步骤基本实现了对空调温度的控制，当然里面的细节有时还是需要大家认真对待哦。
