第一次接触BACnet ip,开发语言使用java,网上搜了下,都是推荐使用BACnet4j,但是找不到完整的demo,折腾了一段时间,勉强跑通了自己写的demo,读取到的设备模拟器上的数据。
1.下载Yabe设备模拟器
链接: https://pan.baidu.com/s/1OK1uq-tfU-XoOH10h4Otag 提取码: 4eu4
安装后
打开太阳的图标
这是设备模拟器,Yabe还提供了一个客户端,打开放大镜图标
可以在client端看到相关的数据信息。
2.下载BACnet4j
https://github.com/infiniteautomation/BACnet4J
下载需要的版本,本博文的代码使用的是5.0.2版本,然后本地安装 mvn install -Dmaven.test.skip=true
3.写demo代码
创建maven项目,pom.xml引入BACnet4j(上面下载安装的),比如
<dependencies> <!-- https://github.com/infiniteautomation/BACnet4J --> <dependency> <groupId>com.infiniteautomation</groupId> <artifactId>bacnet4j</artifactId> <version>5.0.2</version> </dependency> </dependencies>
