Embodiment Construction

[0052] The present invention is described in detail below in conjunction with accompanying drawing:

[0053] Under "Industry 4.0", the present invention divides the new manufacturing network into the following four sub-layers:

[0054] 1) Cyber-physical subsystem layer: contains multiple cyber-physical subsystems, such as collaborative planning system, mechanical drive system, single sensor system, control system and production management system. These cyber-physical subsystems contain multiple types of physical sensors.

[0055] 2) Wireless sensor network layer: including various wireless sensor networks. For different cyber-physical subsystems in a smart factory, there exist multiple heterogeneous wireless sensor networks. The sensors of these networks contain temperature, pressure, displacement, thermal energy, vibration and noise data in modern production and production processes.

[0056] 3) Sensor cloud layer: handles the virtualization of physical sensors and other r...

Abstract

The invention discloses a low-overhead industrial wireless sensor selection method, proposes a new type of manufacturing network framework, and designs a resource scheduler for selecting the current information of suitable available physical sensors to formulate the overall virtual sensor instantiation results , so that the concurrent sensing requests of all users are efficiently mapped to the sensor cloud; compared with the traditional method of directly invoking physical sensors to obtain data, the present invention is more suitable for large-scale node deployment of industrial wireless sensor networks; the method of the present invention starts from From the perspective of the network manager, how does the CPS manager select physical sensors to instantiate virtual sensors, so that the concurrent sensing requests of all users can be efficiently mapped to the sensor cloud, thereby minimizing the overall network overhead.

Description

technical field [0001] The invention belongs to the technical field of industrial wireless sensor networks and sensor clouds, and in particular relates to a method for selecting industrial wireless sensors. Background technique [0002] With the introduction of the concept of "Industry 4.0", the amount of data in the industrial field is growing explosively, which brings great challenges to data acquisition and management. "Industry 4.0" realizes the vertical integration of the manufacturing network under the smart factory by studying intelligent production systems and processes, as well as network distributed production facilities. Under "Industry 4.0", massive amounts of data in the manufacturing system are acquired and coordinated by building a Cyber-Physical System (CPS, Cyber-Physical System). CPS under "Industry 4.0" includes two aspects: Wireless Sensor Network (WSN, Wireless Sensor Network) and sensor cloud (SC, SensorCloud). WSN is composed of a large number of sen...
