DAS 多系统 设计结构
In our previous MITS system, we employed Windaq as the desktop controller, paired with an Arbin system. Typically, this setup involved a primary IV system, which might be connected to several auxiliary machines. However, this architecture was inherently limited: each controller center (PC) could only communicate with and control a single Arbin system at any given time. This restriction was due to our system's reliance on recognizing each machine through a singular IP address.
背景介绍
While we explored solutions that allowed for multiple machine connections via an internet switch, these approaches were still burdened with significant limitations, including complexity, latency, and reduced flexibility.
This led us to re-engineer our controller system to overcome these constraints and enable more sophisticated, multi-system control capabilities.
Our solution is the development of a new generation of Windaq software, which we have named DAS (Distributed Application Service).
The key innovation in DAS is the creation of an additional software layer that manages parallel tasks.
This layer facilitates the simultaneous control of multiple Arbin systems by leveraging individual interfaces that are isolated across different subnets (e.g., 196.168.1.x, 196.168.2.x).
Key Benefits of the New DAS Architecture
Streamlined and User-Friendly Interface
多系统控制
采用新结构后，我们可以通过单个控制器（无论是 PC 还是 DAS 服务器）控制多个 Arbin 设备，而无需互联网交换机等额外硬件。这种简化方法降低了系统的复杂性和潜在故障点。
同时执行命令
DAS 架构允许在 100 毫秒窗口内同时执行命令。这种快速响应时间对于高风险测试环境至关重要，因为在这种环境下，延迟可能会影响数据完整性或测试结果。
跨系统通信
DAS 最重要的进步之一是其促进跨系统通信以实现同步控制的能力。这意味着不同的 Arbin 系统现在可以进行实时通信并相互协调，从而实现以前无法实现的更复杂的测试场景。
增强型情景处理
新的 DAS 结构在管理复杂的多系统测试场景方面表现出色。例如，它现在可以跨不同的 IV 系统无缝控制辅助机器。
例如，一个 IV 通道专注于捕捉从连接的辅助机器输出的数据，而另一个 IV 通道则通过大电流输出对数据做出动态响应。这种跨系统响应控制在测试效率和精度方面向前迈进了一大步。
集中监控
虽然我们以前的系统可以通过集中监控来观察不同系统的状态，但 DAS 通过实现对这些系统的主动同步控制，在这方面又向前迈进了一步。
这可确保所有系统不仅受到监控，而且还能积极协作，以实现预期的测试结果。
