Abstract
At present, in order to overcome the shortcomings of traditional wired cabling and deployment, including complex construction and high cost, most of the security alarm systems employ ZigBee, Wi-Fi and other wireless technologies, whose communication distance, however, are severely limited. This paper proposes a new type of wireless security alarm system, which uses LoRa radio frequency chip of SX1278 series and adopts a star-shaped network topology to achieve the acquisition and long-distance transmission of data from alarm detectors. It meets the demand of low-cost, wide-coverage for alarm network deployment. Through testing, this wireless security alarm system has the advantages of long transmission distance, low cost, high reliability, and convenient networking. It offers a significant reference for Internet of Things applications, which requires a wide wireless network coverage.
