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。

1、基本介绍

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；

2、硬件产品

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。

3、ip网关配置

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

4、打开海思Igate400网关的扫描工具!

5、thingsboard gateway的bacnet配置

6、启动网关后，在云平台的设备列表得到bacnet的设备
