Description

Technical Field

[0001] The present invention relates to the field of wireless communications, and in particular to a perception and data transmission method based on polarization resource management for industrial Internet. Background Art

[0002] The Industrial Internet is based on the network interconnection between machines, raw materials, control systems, information systems, products and people. It realizes intelligent control, operation optimization and production organization mode transformation through comprehensive and in-depth perception, real-time transmission and exchange, rapid computing and processing, and advanced modeling and analysis of industrial data. With the increasing number of industrial Internet devices and the rapid expansion of construction scale, the Industrial Internet still has many defects in meeting data perception, data processing, data analysis, wireless resource utilization, transmission delay and energy consumption, and data security.

[0003] In the resource-limited industrial Internet system, on the basis of meeting the equipment latency and energy consumption, time domain, frequency domain and power domain resource management are adopted. By dividing the time, frequency and transmission power of the wireless communication system, the uplink and downlink selection and resource allocation are optimized, and the spectrum efficiency or energy efficiency of the system is improved. However, the above research does not fully consider the network heterogeneity and the scarcity of wireless communication resources caused by large-scale IoT devices in the industrial Internet scenario. In addition to the above available resource domains, polarization is also one of the resource domains available to communication devices. Polarization resource management can be achieved by dividing the polarization resources available to communication devices. Existing research focuses on the problem of interference avoidance between small cells and macro cells, and proposes to use orthogonal polarization resources to achieve interference-free coexistence of heterogeneous cellular networks. However, the depth and breadth of research on polarization resource management and application in the industrial Internet are far from matching its importance. Summary of the invention

[0004] The purpose of the present invention is to solve the problems raised by the existing background technology. In order to achieve the above invention purpose, the present invention provides the following technical solutions: a perception and data transmission method based on polarization resource management of industrial Internet to improve the above problems. The present application is specifically as follows: comprising the following steps:

[0005] Step 1: The perception control center sends a perception request to the wireless resource management center and requests allocation of wireless resources for the perception device;

[0006] Step 2: The wireless resource management center receives the resource allocation request sent by the perception control center, and sends the resource allocation decision to the perception control center and the data transmission control center;

[0007] Step 3: The perception control center receives the resource allocation decision of the wireless management center, and sends the corresponding perception signal configuration information to the corresponding perception transmitter and receiver respectively, where the perception signal configuration information includes polarization state P1, time slot T = {1, 2, ...T} and subcarrier f = {1, 2, ...f}. The data transmission control center receives the resource allocation decision of the wireless management center, and sends the corresponding data transmission signal configuration information to the corresponding data transmission device respectively, where the data transmission signal configuration information includes polarization state P2, time slot T' = {1, 2, ...T'} and subcarrier f' = {1, 2, ...f'}, and satisfies P1. H P2=0,

[0008] Step 4: After receiving the sensing signal configuration information and the data transmission device configuration information respectively, the sensing device and the data transmission device send and receive signals according to the configuration information requirements;

[0009] Step 5: The wireless resource management center updates the resource allocation decision, and the perception control center and the data transmission control center receive the updated configuration information of the wireless resource management center, and need to send the updated configuration information to the perception device and the data transmission device respectively, and the perception device and the data transmission device will send and receive new signals according to the updated configuration information;

[0010] Step 6: The perception control center calculates the perception performance, and the data transmission control center calculates the data transmission equipment performance. When the perception performance (error probability P e ) is higher than the specified threshold Γ1, that is, P e >Γ1, or the data transmission equipment performance (spectral efficiency SE) is lower than the specified threshold Γ2, that is, SE<Γ2, a request is sent to the wireless resource management center, and a request is made to reallocate wireless resources.

The mutual interference between the perception devices or the mutual interference between the data transmission devices is prevented by adopting time slot division and frequency division multiplexing resource management methods, and devices of the same type are not allowed to communicate at the same frequency at the same time, thereby avoiding mutual interference between homogeneous devices.
