GSM Based Wireless Alarm System for Smart Lock Cylinder

Based on the coded address and 315 MHz wireless transceiver of the smart lock cylinder, a wireless alarm system is designed using the STC12LESA60S2 microcontroller and GSM SIM900A module. With the sketch maps of hardware and the flowcharts of software, the principle of the system is introduced in detail and the key techniques are clearly elaborated for wireless transceiver, GSM AT control and data management. It is verified by the experimental results that the addresses of lock cylinders can be matched and the numbers of alarm calls can be preset. The real time alarm information of the wireless signals transmitted from the electrical lock cylinder can be collected in the range within a radius of 20 m under the conditions of no barrier. Real time GSM alarm can be sent accomplished as phone call or SMS to the preset mobile. The received alarm can be saved in EEPROM for further record data inquiry and database processing. The designed GSM based wireless alarm system for smart lock cylinder can be widely used in a company or family as a local security technology.
