基于无线传感与FPGA的智能报警系统的设计

摘要

This paper introduces the hardware composition of the intelligent alarm system based on wireless sensor and FPGA, explains the design principles, and puts forward the application field of this system and the development prospects. The design mainly consists of a household smoke monitoring instrument, a household gas monitoring instrument, a household infrared detector, and a GSM driving module. The household smoke monitoring instrument and gas monitoring instrument adopt the smoke concentration sensor monitoring MQ-2 to detect smoke and toxic gas to prevent fire and poisoning; The household infrared monitor uses HC-SR501 type infrared sensor to keep watch on invaders, and FPGA controller will deal with the alert signal received from the modules, and then drives GSM module to send messages in order to inform the user. After the actual test, the design can effectively prevent the occurrence of safety misadventures in the home.%本文介绍了基于无线传感与FPGA的智能报警系统的硬件组成部分并阐述了报警系统的设计原理，提出了该系统的应用领域与发展前景。本设计主要包括家用烟雾监测仪器的设计、家用煤气监测仪器的设计、家用红外探测器的设计、GSM驱动模块。家用烟雾监测仪器和煤气监测仪器可以通过MQ-2型气体传感器监测烟雾和有毒气体的浓度来防范火灾和中毒的发生；家用红外监测器通过HC-SR501型红外传感器监测入侵者发出警报，当FPGA经由RF收到各模块发送的报警信号并作相应处理后，驱动GSM模块发送短信通知用户。经过实际测试，该设计能够有效地防范家庭安全事故的发生。
