Embodiment Construction

[0023] The specific implementation of the system will be described below in conjunction with the working principle of the present invention.

[0024] The present invention combines the Verilog HDL hardware description language and the principle diagram method to realize the redesign of FPGA, flexibly control the scheduling mode of the polling system, and control the server to send the information of each site according to the strategy of full service of the central site and threshold service of the common site, and the control system Every time a common site is served, it is necessary to check whether the central site needs service again, so that the service quality of the central site is guaranteed.

[0025] A simple polling process can be expressed as the information packet arrival process of each station, the information packet service process and the polling conversion process of adjacent stations. Therefore, the main realization content of the invention is: use the princip...

Abstract

The invention relates to an FPGA-based polling system distinguishing priority, and belongs to the field of wireless sensor network communication. According to the system, a MATLAB tool is skillfully employed, and frequency division technology is utilized to generate original information sub-groups obeying Poisson distribution; a Verilog HDL language is utilized to control transfer of a state machine, control on a system service order is realized, and hybrid scheduling on full service of a high-priority site in the system and threshold service of normal sites is realized; and an asynchronous FIFO soft-core built in an FPGA is utilized to cache and send site information, and speed matching of arrival and sending processes of the information sub-groups of all the sites is effectively realized. A server carries out full service in a prior manner for the central site, and provides threshold service for the normal sites, central-site services are enabled to have a better time delay characteristic, consideration to services of the normal sites is also given at the same time, the problem of phase staying or frequent-switching in systems is effectively avoided, control is flexible, and thesystem of the invention can be widely applied to multi-service systems which distinguish priority and have higher requirements for time delay characteristics.

Description

technical field [0001] The invention relates to an FPGA-based polling system for distinguishing priorities, which belongs to the field of wireless sensor network communication. Background technique [0002] As a reconfigurable infrastructure, wireless sensor networks have the characteristics of generality, flexibility, maintainability, self-organization, and learnability. They are widely used in agriculture, industry, military and other fields. Polling systems are , high efficiency, practicality, high quality of service and other characteristics are widely used in wireless sensor networks. The wireless sensor network is a multi-hop self-organizing task-based network system composed of miniature sensor nodes through wireless communication. It is a distributed system. The sensor nodes form a number of clusters through dynamic reorganization to effectively avoid single point failures. , strong maintainability, improved system survivability, automatically forwards detection dat...
