Design And Implementation Of Equipment Environment Monitoring System With Voice Control Function

With the improvement of industrial productivity and development of industrialization,economic and society,many highly automated production equipment are used in modern production in various fields.However,it should be pointed out that during the operation of production equipment,production equipment failure often has safety risks because of surrounding environment.so it is necessary to install a monitoring system to perform real-time operation monitoring of the production equipment.However,the traditional monitoring system makes the operation interface more complicated and a lot of buttons will cause misoperation.To solve this problem,this article proposes a method to use intelligent speech recognition to replace the traditional buttons to operate the equipment environmental monitoring system in order to improve user experience.In order to solve the problem that user’s voice commands may mix with other words to make the function matching difficult,this paper proposes to use HMM+Viterbi algorithm in word segmentation and combined with HashTable’s matching method to analyze the voice commands and extract the keywords to make the text and functions match.In order to solve the concurrency problems existing in the operation of system,this paper uses multi-thread combined with thread mutex lock to ensure that the function modules operate independently and contact each other.This article will implements the environmental monitoring system of equipment with voice control from four parts:1.In this paper,a noise reduction algorithm based on dual-channel RLS adaptive filtering noise is used to enhance the signal of input voice.Then recognize the enhanced speech and output the result.2.Firstly using HMM+Viterbi word segmentation algorithm in to segment the text result and get the results of segmentation.Then making a keywords set which obtains all defined functions and the word after segmentation will be compared with the keywords set,and the keywords in the word after segmentation will be retained.3.Design the common functions of the monitoring system,and use the method of text vector similarity comparison(doc2vec)to construct the Q&A interactive function.Using HashTable to establish the mapping rules between keywords and functions.The purpose of mapping rules will make sure that keywords can only match certain function.And design hardware and connection between each component when the system function is running.4.The whole monitoring system will be implemented by using soft based on MVC design architecture,including the system GUI operation interface,the background functions and the system design code will be integrated.Multithreading and mutex locks are used to solve the concurrency problems encountered in the system operation.Finally,considering the feedback operation of software,the system is designed some common error and confirmation prompts during the running time of monitoring system.This paper has achieved the expected results by using input voice signals to control the equipment environmental monitoring system.The system runs quickly and accurately from input voice to function running and every part of monitoring system can work well.And the operation interface of monitoring system becomes more friendly and concise because of using voice control.
