In this article, this embedded system and GPRS module to simulate the security monitoring, intelligent security monitoring system, anti-theft, fire system is to monitor real-time infrared sensor, start the GPRS system to send text messages to the specified number or send to give 119 fire alarm when abnormal situations. The fire alarm system using temperature sensors to collect the temperature through the A/D conversion, the ADC device simulation fire use development board, when the temperature is higher than the preset temperature value, system start alarm bell and send messages to the specified number. Anti-theft system is to simulate the thief by key module, to achieve the perfect monitoring. Users can go to the monitoring computer through the Internet network to log in using the system, the control button is clicked in the webpage to open / close the monitor alarm system and fire alarm system, real-time situation can view monitoring site and can be the scene manual by taking pictures, you can also browse in the accident when monitoring machine automatically save pictures, can be powerful evidence for the user. Hesitate equipment sake, video equipment is not reflected in the pap
