Research on Smart Phone Voice Circuit

Intelligent guard system is composed of a piece of 89C51, all kinds of guard against theft, fire, gas leak detectors, sensors and all kinds of alarm, siren, lights, voice alarm system, telephone system, etc. By microcomputer processing chip and all - weather wireless remote monitoring technology, the system performance is more reliable, and the installation and operation are simpler. This sys- tem consists of a single alarm host installed in the location of the hidden in the master room. Meanwhile various configurated sensors can be manipulated by phone or hand. When all kinds of sensors receive the signal under the case of system for protection, they will transmit data by wireless or wired way immediately to circular dial - up voice call to the police through the alarm host outward circular dial - up voice call the police. With the simple installation and operation, the system completely solves the limitation of space and distance and it is a kind of intelligent guard system.
