【正文】 visual alarm). We design the system must have the following function module: infrared detector, alarm, automatic dialup function。 Infrared detector, Acoustooptic alarm circuit。 Power supply circuit, Working state instructions circuit. Its system working principle for: the sensors will be detected signals to lead signal processor processing, microcontroller judgment to mouth have pulse falling edge jumping signal immediately transferred to the acoustooptic alarm program, at this moment, the red light buzzer alarm rapid flashes, lasted 30s. In the 30s inside if someone press the switch, then eliminate alarm remove alarm. if this time no one remove alarm, the proof nobody at home in 30s system will automatically triggers telephone finish the whole system of police work project. Later, microcontroller will continue to cycle back ? sentenced system total diagram In proteus simulation system, the system circuit by crystals circuit, soundlight alarm circuit posed. Among them, we use connect the dedication of the simulated infrared sensors, requirement when switch when pressed by the high jump, level is low, the equivalent of, sensor detects the state of man, the telephone line with and derivation, here without simulation telephone circuit diagram. Figure 3 software system design control module design program Microputer in the initial plus electric, voltage is not steady state, causing instability, at this time the SCM in monly after power up to system with a piece of delay. Timelapse after detecting P1 mouth microcontroller state, detection level signal whether mutations, if is then calls the police processing procedure, including automatic dialup audible and visual alarm procedures, if no changes, ChuXiang level detection continues to P1 mouth state. Figure main program flowchart system development adopted by the programming and missioning of the platform This system language using assembly language preparation, so choose wave6000, he has the microcontroller program edit, pile and debugging, etc., and generate hexadecimal. Files, through: machine TOPWIN burning software writeable microcontroller program memory. The simulation software use Proteus, he is from Britain Labcenter electronics pany EDA software. The circuit of the simulation is interactive, aiming at the microprocessor application, still can directly based on schematic diagram of the virtual prototype programming, and implementing software source code level of realtime debugging, if have display and output, still can see after the oper
