FPGA achieved intelligent head display device based on multi-frequency wireless networking module

Abstract

The invention proposes a FPGA achieved intelligent head display device based on a multi-frequency wireless networking module. The FPGA achieved intelligent head display device comprises an intelligent head display device body and an FPGA control chip encapsulated in the intelligent head display device body, wherein the FPGA control chip is used for achieving the multi-frequency wireless networking module, a microcontroller receives acquired data from an external sensor through an external interface, conducts analysis and processing on the acquired data, configuring corresponding wireless protocols according to different demands of the data and sending control instructions to a radio-frequency switch according to the configured wireless protocols, the radio-frequency switch is switched to the corresponding radio-frequency module according to the control instructions of the microcontroller, the radio-frequency module outputs radio-frequency signals to achieve corresponding wireless protocol sending data. The FPGA achieved intelligent head display device simultaneously achieves wireless network transmission of one or more protocols through network configuration, adopts FPGA design and is simple in structure and small in resources consumption.

Description

technical field [0001] The invention relates to the technical field of Internet of Things wireless modules and smart devices, in particular to an FPGA-based smart head-mounted display device based on a multi-frequency wireless networking module. Background technique [0002] Smart Head Mounted Displays (HMD) have the advantage that users can watch images and information in real time. HMDs first started with consumer use and business use. HMD is in the highly interesting fields such as video audio-visual and sports, and the demand for HMD is increasing day by day. Coupled with the progress of its components, there has been a trend of popularization. With the downsizing and weight reduction of HMDs, the development of HMDs is becoming increasingly active. In addition to the fields of sports and entertainment, proposals conceived for use in everyday life have sprung up one after another. For business use, there are companies that use it for operation support and design supp...

Problems solved by technology

However, in actual communication, the actual channel changes are very complicated, and the signal-to-noise ratio changes frequently, so the method of pre-fixing the number of iterations will cause the decoding speed to be too slow and the efficiency to be low. This solution is not advisable.
