Based On Intelligent Security Products And DTMF Applications Of Hardware And Software Design

With the development of economic integration,security industry in the global scope has been more people's attention,its products more and more,the market also will expand and develop.In today's production and life,relatively professional security products are used in various fields,such as in the financial and home life,the city's security construction,transportation industry has played a significant role.In the early days,security products have relatively shortcomings,the operation is more difficult and complex,the network installation is not easy to grasp,the probability of false triggering,and the market usage is low.And now,the latest security products to change the transmission before the cable for the product,with the popularity of things,the use of more advanced sensors and wireless transmission technology,combined with new industrial design,easy to use,easy to network,easy to install,The latest technology with high reliability.At present,more and more users recognize the security products,and has been from the public domain to the home and other places of the transition,the use of more and more widely.This article is a smart security product developed by Shanghai Mobile Communication Technology Co.,Ltd.,using the GSM / GPRS module M50,it has many advantages,such as the global GSM environment can work,a variety of operations Method SMS / GPRS / CALL,can use OpenCPU for embedded programming,support DTMF codec,through the PC,mobile phones and other intelligent terminal follow-up view.At the same time there is a very powerful TTS voice function.This product uses the GSM communication module,enhanced the operation,the access method uses a variety of remote methods,the global GSM environment can be used to be able to use both images and voice,compared to existing products,This product is relatively high cost performance,availability is strong.This article is divided into the following aspects to discuss,DTMF codec,GPRS,TTS,closer to the wireless transmission,the main study of these functions and their respective background requirements,how to improve the intelligence of this product,how to improve its The degree of integration and how to improve the price.Although this article is not committed to the realization of this cost-effective security products,but will continue to study 3G / 4G wireless communication technology,in this technical level,based on the expansion of security products,such as real-time transmission of video,Multi-person life to provide security and convenience,to enhance the popularity of security products.
