Comprehensive performance index testing system for wearable/contact human communication

Abstract

The invention particularly relates to a wearable / contact type human body communication comprehensive performance index testing system, belonging to the testing and measuring field. The system has thefunctions of generating and controlling human communication signals and testing and displaying human communication signals at the same time. The human body communication signal generation and controldevice mainly comprises an industrial control computer including an application program of the human body communication transmitting end, a test signal generation unit, an audio and video signal generation unit and a signal isolator. The human body communication signal generation and control device comprises a human body communication transmitting end application program, a test signal generationunit, an audio and video signal generation unit and a signal isolator. The testing and displaying device of human body communication signal mainly comprises an industrial control computer including anapplication program of the human body communication receiving end, a testing signal receiving unit, an audio and video signal receiving unit and a signal isolator. Compared with the conventional testing technology, the invention can only measure the single parameter of the human body communication system, and has the disadvantages of long testing time and low testing efficiency. The invention hasthe advantages of fast measurement of multiple parameters, high safety and high efficiency.

Description

Technical field [0001] The invention specifically relates to a comprehensive performance index test system for wearable / contact human body communication, which belongs to the field of test and measurement. Background technique [0002] Human body communication technology is a new type of information interaction technology based on human body media. As a short-range communication technology that integrates the human body into the information exchange channel, this technology modulates information into an active quasi-electrostatic field and couples it to the human body to generate a weak electric field signal. At the receiving end, the transmitted information is detected and demodulated to realize near-field data communication using the human body as the signal transmission medium. From the perspective of information interaction, human body communication can be divided into wearable human body communication and contact human body communication. Among them, wearable human body co...

AI Technical Summary

Problems solved by technology

[0009] At present, existing research at home and abroad mainly uses conventional testing techniques to measure individual parameters of the human body communication system. In addition, it is impossible to effectively measure the human body communication system in the wearing situation.

The lack of a test system that can comprehensively measure the parameters and performance of the human body communication system results in a long test time for the performance indicators of the human body communication system and low test efficiency, thus limiting the development and application of human body communication technology
