Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0041] Such as figure 1 As shown, a schematic diagram of MW-Voronoi subdivision of 1 node with 4 neighbor nodes, S 1 ,S 2 ,S 3 ,S 4 ,S 5 is 5 nodes, where S 1 Adjacent to the remaining 4. V 1 , V 2 , V 3 , V 4 node S 1 The four vertices corresponding to the boundary of the subdivided area. o 12 , O 13 , O 14 for each node S 1 The center of the auxiliary circle made by the divided boundary, because S 1 , S 5 The weights are the same, and the dividing line of the subdivision area between the two is the bisector of the connecting line, so there is no O 15. Specifically, the geometric figure is obtained according to the definition of MW-Voronoi. This kind of symbol indicates the significance of a split edge, which means that its weight ratio with adjacent nodes is Each edge interse...

Abstract

The invention discloses a deployment method of sensor nodes for manufacturing the internet of things. The sensor nodes are randomly deployed in a detection area; the sensor nodes broadcast information around, and all the sensor nodes can be communicated through information exchange and collection; hot spot location dynamic changes in the area are detected, location dissections of the sensor nodes are calculated according to hot spot location dynamic deployment and an MV-Voronoi method, the position of the maximum weight point is looked for in a dissection area of the sensor nodes, the sensor nodes gradually move to hot spot locations, the hot spot locations are determined, and a hot spot MV-Voronoi covering area is determined; if the weight value of a new hot spot MV-Voronoi covering area is larger than that of the hot spot MV-Voronoi covering area, the sensor nodes move to new hot spot locations. The deployment method is high in efficiency, low in energy consumption and high in automation degree, the density of the nodes is controllable, and a deployment graph having a moving characteristic is formed.

Description

technical field [0001] The invention relates to artificial intelligence topology control technology in the field of manufacturing Internet of Things, in particular to a deployment method of manufacturing Internet of Things sensor nodes. Background technique [0002] The Internet of Things realizes the interconnection of things to things, people to things, and people to people, and expands the interconnection between people realized by the current network to the scope of things through sensing technology. The core of the Internet of Things is to realize the interconnection between things, so as to realize the active information exchange and communication between all things. [0003] Manufacturing Internet of Things is the integration of electronic information technology such as network, embedded, RFID, sensors and actuators with manufacturing technology to realize dynamic perception, intelligent processing and optimal control of manufacturing resources and information resourc...
