Description

technical field [0001] The invention relates to the technical field of the Internet of Things and cloud computing, in particular to a system and a method for cloud real-time simulation of a perception device of the Internet of Things. Background technique [0002] The rapid development of cloud computing technology and Internet of Things technology will definitely bring a huge change to human production and life. The development of Internet of Things technology cannot be separated from the support of cloud computing technology. Sensing devices are the most basic elements for building the Internet of Things. With the continuous expansion of the application scope and scale of the Internet of Things, the number and types of IoT sensing devices are also increasing. Different types of data, the processing of multiple types and types of big data needs to be supported by cloud computing platforms. [0003] An important feature of the Internet of Things is the interaction and linka...

Problems solved by technology

However, due to the complexity of devices and networks, direct communication between devices and between services and devices is greatly limited, and the efficiency of real-time linkage between multiple devices, especially between multiple devices in different regions is relatively low. Low

[0004] When the cloud service program needs a large amount of real-time data from different types of IoT sensing devices in different regions at the same time, the way of direct communication with each device will not only bring a huge load to the network and cloud server at the same time, but also cannot guarantee the same time. Get the latest data for all devices

[0005] When multiple applications or service programs access the same IoT-aware device at the same time, the same device may communicate with multiple applications or service programs at the same time, which may cause access conflicts to the same device

[0006] The security guarantee of the Internet of Things system is an extremely important aspect of the Internet of Things technology. In the future, the linkage of IoT sensing devices will inevitably require mutual opening between sensing devices or between sensing devices and cloud service programs. The direct opening of devices will inevitably give sensing devices itself and the network where the sensing device is located pose a huge security threat
