关于客户
PaceControls 是一家领先的技术开发商和制造商，为供暖、通风、空调和制冷 (HVACR) 行业提供基于云的物联网 (IoT) 解决方案。他们开发了第三代产品，即基于Android的4G LTE/Wi-Fi/ZigBee无线能源和智能电网产品套件，名为PACE+PACE Cloud。 PaceControls 技术位于恒温器和 HVACR 设备之间，接受恒温器控制信号和其他信号以产生优化的控制信号，从而最大限度地减少 HVACR 设备的能源使用。在大型商业设施中，屋顶机组 (RTU) 网络提供供暖和制冷。 PACE 节点安装在每个 RTU 上，并通过 ZigBee 网络相互通信。
挑战
PaceControls 是 HVACR 行业物联网解决方案的领先技术开发商和制造商，在控制 HVACR 设备方面面临着重大挑战。 HVACR 系统有各种配置和尺寸，范围从单压缩机/单风扇到多压缩机/多风扇单元。 PaceControls 开发的技术必须足够灵活，能够适应 10 种主要的 HVACR 配置，每种配置都有 200 多种单独的要求。挑战包括管理需求和算法复杂性、易于安装和使用、准确估计节省费用等等。该技术还需要支持 Wi-Fi、ZigBee 和 4G LTE 通信以及无线 (OTA) 固件更新功能。
解决方案
PaceControls 依靠 SolidThinking Embed (sTE) 实施基于模型的设计 (MBD) 流程来开发其节能算法。 MBD 流程由仿真和硬件在环 (HIL) 测试组成，Embed 完全支持该流程中的所有步骤。在仿真步骤中，系统需求由设计模型表示。创建 HVACR 系统的动态模型，然后对能源和需求优化控制算法进行设计、分析和建模。组合的“控制+工厂”模型经历迭代的“分析+重新设计+仿真”过程，直到其性能处于每个设计模型的可接受范围内。在 HIL 测试步骤中，Embed 自动生成控制器模型的 C 代码。然后，代码使用嵌入支持库编译为 Android 应用程序，并利用连接云的 Qualcomm Snapdragon 微控制器在 PACE 节点上执行。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
