Help Elderly Security Of Information Systems

China as early as the late twentieth Century has already entered the aging society, the agingpopulation in China is more and more serious, can be said to be the aging problem throughouttwenty-first Century beginning. According to the current population structure in China, the agedhas become a very serious problem. Now the network, the media often reports some elderlypeople living alone, Empty Nester due to some sudden illness or accident, did not receive timelyrescue, thus appeared the tragedy. In order to solve this problem, this paper designs a kind of oldpeople security help information system, a telephone information system of a single memorydialing in the design, so that the elderly do not have to remember phone number, dial call functioncan realize the common telephone number; there is a large screen information display system, theold people can easily see get basic information of incoming information, time and so on; theemergency case can easily realize the safety for help, and can alarm.The elderly help information system security is a concrete application of intelligentendowment examples, but also the future of pension model for the development of a major trend.At present, due to the technical conditions, economic status, ideology and some realistic factors ofthe Elderly Security help system does not have a wide range of applications, only the actualapplication in Hongkong, Guangzhou and other places. The Elderly Security help informationsystem, the design has the advantages of simple operation, convenient old people; high ratio ofperformance to price, the general family can accept.This paper introduces the principle and the realization method of the elderly security systemfor information, and complete the design of the hardware and software. The microprocessor usesPhilips large capacity and high performance micro controller chip P89C58UBPN, FSK/DTMFwere detected by HT9032C and HT9172chip, the software part is written in C language, fullyindependent design, realizes the standard signal detection. RS232C computer data communicationinterface using MAX232chips, directly and computer communication.In this paper, according to the FSK/DTMF double system calls information detectiontechnology, key storage, one touch dialing technology, large screen display technology, analyzedthe principle and design method of the elderly security system for information, and from twoaspects of hardware and software design of the system. In this paper, the design can solve theElderly Security help very difficult situation, improve the life quality of the aged, and has goodeconomic benefit and social benefit. The function of this system can not restricted by time andplace, will be widely used in family, community, nursing homes, the elderly need to get aidenvironment.
