The Software Design Of The Infrared Wireless Alarm System Based On MMS

Along with the high speed development of social economy and unceasingly enhancement of people living standard,people's life demand also becomes diversifies,therefore the family guards against the demand to arise at the historic moment peacefully,which causes the intelligence security alarm system and the inhabitant daily life more and more close.The guard system which take the family housing safely as the goal obtained a certain degree development.After consult correlation domain material and literature,i found that many problems exist in most of the present family security system,for example,simple function, easy to suffer the destruction, the accuracy which reports to the police is too low and so on.Along with the family Safe Guard development demand, can meet the user need, the performance is reliable, the economy practical security alarm system has the broad prospects for evelopment.This article has designed take the GPRS correspondence theory as a backing, uses the MMS technology and based on my schoolmate of hardware designs of infrared wireless alarm system based on MMS.Compared with the former security alarm system,this system unified the MMS image transmission technology,the sensor of infrared light electric technology, the wireless signal transmission technology,use family computer and the mature embedded technology.It has enhanced the accuracy of reporting to the police,strengtheded user's initiative,reduced the cost.So this system has the very big demand market in the domin of family safe guard and can produce good social efficiency and economic efficiency.This system has two key technologies:one is the MMS coding and transmiting,the second is the SMS coding,transmiting and receiving.MMS,as a new image transmiting technology,it's biggest characteristic is that it could support the multimedia functions,can transmit the writing, the image, the sound and so on.The data transmission capacity is small,the monitor to scene is more user friendly, the accuracy of reporting to the police is enhanced.The article in the analysis MMS work principle, the MMS network architecture, the MMS code language foundation, has completed the MMS image transmission.The SMS technology, as an universal used information transmission method, it's biggest characteristic is that the technology is mature, quickly convenient.The article in analyzed the SMS code pattern, the control command foundation has completed the SMS transmission receive function.Finally we used the mature embedded technology, the image compression processing technology, have completed the alarm monitor, image gathering, the compression module software design.
