Gated based on the GSM and SMS alarm system design
Abstract
With the rapid development of electronic technology to enable intelligent application of the family more and more widely, the door control system of intelligent devices as an important family member, has been the rapid development of the system and the GSM short message from the single-chip modules, with the most reliable, most mature GSM work, the most intuitive of the Chinese form of short message or telephone directly to the alarm location to your cell phone to reflect on the screen. It uses the GSM-SMS-based gated anti-theft alarm system for a reliable mobile phone and SMS alarm gated convenience. AT89S52 choose the system as a system control chip, based on GSM-based gating and SMS alarm system control, the system es the limitations of the alarm range, work to cover the local region are valid alarm, the system interactive use of text messages to achieve the ultra-distance remote control functions, the system is very suitable for factory floor, warehouse, such as the use of some special occasions. Based on the use of single-chip realization of the GSM-SMS-gated anti-theft alarm system control, wireless control can be achieved not only save manpower and material resources, the purpose of improving management level and has a simple structure, easy to operate, the characteristics of a wide range of applications.
