Valuables Remote Anti-theft Alarm Aystem Based On GSM Modul

It has been a concern how to implement the anti-theft alarm function fast and effectively, when the valuables are stolen. Most of the anti-theft alarm equipment has the disadvantage of high cost, short distance, high false and so on. Valuables remote anti-theft alarm system based on GSM network is a long-range anti-theft alarm system designed by the ripe GSM network technology. As the GSM network has the advantage of the long communication distance, low cost, very little leakage error code, stable and reliable operation, which can be a good solution to the above-mentioned problems.This paper designs a GSM network based remote anti-theft alarm system. This system can realize monitoring alarm and home alarm of the important unattended equipment in the industrial field, it has a wide scope of application. The anti-theft alarm system mainly employs MSP430F149 SCM as the core; combining the front anti-theft alarm system sensors with GSM modules (SIMCOM company TC35I module) realizes the function of the remote anti-theft alarm.This study mainly includes the following sections:1. Overall design of the alarm system. Determining the overall design program of the alarm system according to the option of the alarm system communication platform and achieving the function of the system and comprehensive consideration of the cost of the design and application areas.2. Hardware design of the alarm system. The main control device of the alarm system uses MSP430F149 SCM.Various parts of the hardware electric circuit are designed, including electric circuit design of the SCM control system, level-shifting circuit design, buttons circuit electric design,GSM module electric design, and so on.3. Software design of alarm system. According to the design function of the alarm system, software design of alarm system use C language. Through the GSM module sends the short message alarm to permissive mobile phone users to realize the function of the valuables remote wireless monitoring and other functions around the clock.The system finally has completed the required basic function of the subject, and the system runs and texts. It can easily be applied to different monitoring areas only making changes slightly. Therefore, the design and implementation of this system has a certain theoretical significance and practical application value.
