[图解]SysML和EA建模住宅安全系统-11-接口块

1
00:00:00,660 --> 00:00:04,480
接下来的步骤是定义系统上下文

2
00:00:04,960 --> 00:00:07,750
首先是图17.17

3
00:00:09,000 --> 00:00:10,510
系统上下文展示了

4
00:00:10,520 --> 00:00:12,510
ESS和外部系统、用户

5
00:00:12,520 --> 00:00:14,190
和物理环境的接口

6
00:00:15,480 --> 00:00:16,990
它是通过一个

7
00:00:17,000 --> 00:00:18,350
内部块图

8
00:00:18,780 --> 00:00:22,320
来展示的，一个运营领域

9
00:00:24,110 --> 00:00:26,220
block的内
