ABSTRACT
With the continuous improvement of people's living standards, burglary happens from time
to time, especially in today's highly developed modern technology, the crime tends to be more
intelligent and the means are more concealed. Therefore, the equipment and equipment based on
electronic technology, sensor technology and computer technology for security and prevention
technology will form a system, which will play the largest role. Because infrared ray is invisible
and has strong concealment and confidentiality, it has been widely used in security devices such
as anti-theft and warning devices
The first chapter of this design mainly describes the current situation of the engineering
design and implementation of home monitoring and anti-theft system, and analyzes the
advantages and functions of various sensors through the human body sensors used in the current
society. The second chapter mainly describes the project analysis of home monitoring and
anti-theft system design and implementation, through the design requirements of the paper to
choose the most appropriate design scheme, whether it can meet the current design requirements,
according to the design requirements to select components, drive circuit selection. And draw out
the design framework by using visio. The third chapter mainly introduces the hardware design of
the engineering design and implementation of the home monitoring and anti-theft system, which
respectively explains and analyzes the circuit principle of the minimum system of the single-chip
microcomputer, the key module, the alarm module, the human body sensor module, the buzzer
module and the LED display module, and finally summarizes the whole circuit. The fourth
chapter mainly describes the software design of the engineering design and implementation of
home monitoring and anti-theft system. The programming software keil is introduced in detail,
and the program flow of single module is compiled. The program is composed of key module,
alarm module, human body sensor module, buzzer module and LED indicator module through
the flow chart. The fifth chapter mainly describes the design and implementation of home
monitoring and anti-theft system, welding circuit and verifying whether the designed functions
meet the requirements.
At the end of the paper, the whole system is tested and recorded in detail, through which the
