The intelligent telephone alarm system is designed with a single chip microcomputer as the core of system,and the intelligent system is controlled by AT89C51. A telephone network is used as transmission of voice digital information in the system. The telephone alarm is composed of a single-chip microcomputer control, sensor and signal input circuit, and DTMF send and receive circuit, voice controlling and receiving circuit, alarm telephone circuit. According to the different sensor output signal, it can send out different alarm information to realize remote monitoring function.

Test Result

In this paper, a multi-purpose alarm system for dormitory based on control conducted by AVR single-chip microcomputer is designed and produced, which aims at potential safety risks existing in dormitories of colleges and universities at present. This system uses multiple sensors to realize detection of human body, smoke, access of people and valuables, after which signal will be processed and AVR single-chip microcomputer will then be used to realize automatic control. Host computer receives information from slave computer and then realize long-distance and real-time monitoring. Test result indicates that this system functions well and can realize security of student dormitories if applied, which can raise audible and visual alarm in case of abnormal situation and realize cancel of alarm through entering password on a keyboard.

in order to improve the security of home residence, this paper studies and designs an intelligent home security alarm system, using STC89C51 single chip microcomputer as the main controller of the security system, and real-time monitoring by controlling the human pyroelectric infrared sensor and smoke sensor in the case of strangers invading the security range and showing signs of fire. Once the abnormal situation is found, the intelligent home security alarm system will start the acousto-optic alarm prompted by the LED lamp and pass through the information processing system of the GSM module. Send an abnormal text message to the user of the security system at the first time face, and finally realize the purpose of modern intelligent home security alarm.

The NC Teaching Plotter is designed for the practice teaching needs of NC machining, In order to improve current existing practice teaching environment of "many student, less equipment". It explains the NC concept with concise way and demonstrates NC thought by the intuitive operation.In this paper, the design of NC teaching plotter makes interpolation motion between pen and table based on NC program in accordance with the requirement made by user, to draw the graphics by moving the magnet control brush painting through the single chip digital control and the two stepper motor control X, Y two axes feed. The NC teaching plotter which demonstrates more clearly and directly the numerical control idea has high practical value for teaching practice.
