Abstract


Turn the request of family living environment to raise continuously to the intelligence along with the society, the supervision system of the family long range is the importance of the intelligence small area to constitute part, being subjected to the extensive concern of market.This text discussed the development present condition of domestic and international intelligence safe anti-theft equips first, and according to the present condition of the trend and our country of technique development, the research designed a kind of intelligence a safety to guard against theft to report to the police system.Adopted through the passive type improved a design red unauthorized biography feeling a machine in this text, it was the characteristic which releases to give or get an electric shock a sensitive component according to the heat and combine certain optical system to construct to make into of, can identify effectively for stealing intentionally slow-moving ambulation of stealing, strengthen the intelligent and the credibility of the system.The outer circle electric circuit has DTMF electric circuit, stir number electric circuit and flap bell monitor, speech electric circuit...etc. to constitute automatically, be some all the way the locator examine feeling of time, would toward the AT89C51 correspond of the I/O send out to report to the police signal, again from the AT89C51 control the telephone connect a people’s electric circuit, carrying out emulation to take off machine, stiring number electric circuit through a DTMF, realization automatically stir number, and is passed telephone completion by the speech electric circuit to broadcast in advance record a good speech information, carry out a speech to report to the police to notify customer occurrence a circumstance.The system increased to establish the locator of smoke and door, is a kind of multi-function protection device.This system mainly resolves to settle an electricity from the diagnosis problem and because the intelligent degree problem of locator causes of fail to report phenomenon, if get stripe system the control that can carry out to the appliance. System establishment at in great quantities related experiment of foundation up, and passed the related test of hardware and software, so have stronger physically applied foreground, and have certain reference value to the follow-up development.
