应用使能平台 ,即Application Enablement Platform(AEP),又有翻译成应用支持平台,应用支撑平台的。根据字面意思,AEP就是能快速开发部署物联网应用的云平台,常常以平台即服务(PaaS)的形式出现,因此开发出来的应用具有云服务的特性:动态扩展,按需服务,高可用性等等。 应用使能平台是一种以技术为中心的产品,它以与行业无关的可扩展的中间件为核心, 方便用户在平台上开发全新的IoT应用程序或者将原有行业应用迁移或者升级成IoT方案。 根据AEP的定义,大部分AEP能提供图形化可视化开发工具,快速开发模型、中间件、数据存储功能、业务逻辑引擎、对接第三方系统API等等。如果AEP是面向物联网的,那么常常会包括设备管理,设备接入,连接管理等等功能。 如今,AEP在向两个方面发展。首先,随着连接到物联网应用的物体越来越多,所使用的通信技术越来越多样,AEP的基础功能在向更复杂的方向进化: 其次在AEP所集成的功能也越来越多,以上示例给出了最基本的功能模块,但是实际中的应用程序所需要的“能力”,实际上就是云服务却是多种多样的,因此,不同的AEP会集成进许多不同的云服务,而且,所集成的云服务越多,AEP就越强大,给客户带来的价值就越大。 AEP平台帮助企业极大节省物联网应用开发时间和费用,据Aeris测算,开发者使用AEP平台开发应用,和独立开发相比,可以节省70

python 版本的可以参考: https://blog.csdn.net/qq_33811662/article/details/80732275 首先需要一个 ListThings 权限 AWS 的 IAM 帐号,需要获取 access_key 与 secret_key。 需要引用一个 iot 包,此处我是使用 Maven 构建的项目,在 pom.xml 中加入 <dependency> <groupId>com.amazonaws</groupId> <artifactId>aws-java-sdk-iot</artifactId> <version>1.11.347</version> </dependency> 接下去就是代码部分: import java.util.List; import com.amazonaws.auth.AWSCredentials; import com.amazonaws.regions.Region; import com.amazonaws.regions.Regions; import com.amazonaws.services.iot.AWSIot; import com.amazonaws.services.iot.AWSIotClient; import com.amazonaws.services.iot.model

IoT request response protocol

别来无恙 提交于 2019-12-02 20:58:58
We need to build a server that can communicate with some embedded devices running a variant of Android. We need to be able to send commands to the device, and receive a response. A simple command might be asking the device for it's status. We won't have HTTP, so we need to have the client/device establish a connection with the server. We were considering using MQTT as it has a lot of nice properties (QoS, lightweight, built for IoT), but it doesn't natively support a request response workflow. We have considered building RPC on top of MQTT, but before we do I just wanted peoples thoughts on

How does device anti-spoofing work in Azure IoT hub?

梦想与她 提交于 2019-12-02 07:52:08
问题 From Azure development guide https://azure.microsoft.com/en-us/documentation/articles/iot-hub-devguide, there is a small section (shown as below) talking about device anti-spoofing. It is not clear for me, it says IoT hub stamps every message with properties, but for me device anti-spoofing is that IoT hub to stop receiving messages sent from any spoofed device. Please help to explain how does this work? Anti-spoofing properties To avoid device spoofing in device-to-cloud messages, IoT Hub

Azure IoT Hub - “Subscribe” code not working: “connection was refused”

How to display a clock with the current time in a Windows Core IoT app?

一笑奈何 提交于 2019-12-02 03:18:35
I am trying to create an Windows 10 IoT app running headless on a Raspberry Pi 2. Everything is set up correctly and I am able to debug my from Visual Studio using the Raspberry Pi as the remote machine for debugging. Now I want to add a clock on the app page but I can't figure out how to keep the displayed time updated. In plain old C# I would use a BackgroudWorker or something similar to keep the displayed time current, but that type is not available in UWP. I have been looking into "Create and register a background task" on MSDN but that seems to be way to complex, just to be able to keep

基于华为物联网IOT的应用开发 --- 基于.net 的SDK封装

浪尽此生 提交于 2019-12-02 02:48:40
最近,物联网的概念比较热门,一大批厂商抢着占领物联网的高低,包括有华为物联网、阿里云物联网、腾讯物联网、AWS物联网等等,无法一一列举,一般物联网包含设备侧开发、平台侧开发、应用侧开发,三个部分构成了线上线下的完整连接,和我们常规的微信应用、钉钉应用等不同,物联网的终端是由各种各样的设备组合而成,这些设备通过各种不同的协议(如CoAP,LWM2M、MQTT)连接到IOT的平台,而且这些设备是低能耗的设备,可以实时的发送数据上来,也可以接受来自IOT平台下发的各种操作指令。本篇随笔主要介绍基于华为物联网IOT的应用开发,实现对.net SDK的封装,方便后期进行应用集成使用。 1、物联网的相关介绍 物联网其实有点类似我们以前做的一些行业设备的接入,不过它相对比较通用化一些,可以连接各种各样的类型设备,而且更加安全、低能耗等,我们以前接入很多设备,可能需要走TCP/UDP协议,然后在后台服务器有一个对这些设备管理的一个Socket服务器,不过和物联网对比,这些都被彻底改造过了,以便适应更多的 应用场景,更简化的开发,以及支持更强大的功能吧。 物联网目前可以针对一些传感器采集一些特定的参数,如光感、温度、湿度、压力、电压、电流等常规的信息,也可以扩展实现语音、图像、视频等方面的采集处理,如经典的智慧路灯应用场景。 下面是其中的一个应用的架构设计,主要就是针对这些设备管理
