Description

Technical Field

[0001] The utility model relates to the field of security and theft prevention, in particular to an infrared fence detector based on Internet of Things alarm. Background Art

[0002] In the prior art, Chinese Patent No. 2710063 discloses a "mutually beamed multi-beam infrared barrier detector" that includes an alarm device and a pair of infrared monitors positioned opposite each other and electrically connected to each other. Each infrared monitor consists of a housing, a circuit board, a transmitter, a receiver, and a control circuit located on the circuit board. The housing is provided with a light-transmitting window. The alarm device, transmitter, and receiver are all electrically connected to the control circuit. Furthermore, the transmitter at one end of the pair of infrared monitors maintains a one-to-one correspondence between the transmitter and the receiver at the other end. The pair of infrared monitors collaborate to perform detection, achieving data synchronization through an electrical connection. The control circuit then performs corresponding processing based on the synchronized data. As existing factories gradually transition to intelligent automation, the functions of this mutually beamed multi-beam infrared barrier detector are relatively simple and cannot meet the needs of intelligent factories. Primarily, it lacks Internet of Things (IoT) functionality, and the alarm signal data collection and upload technology is cumbersome and costly, resulting in inefficient and timely data transmission to management personnel. Furthermore, its installation is cumbersome, making it difficult to achieve flexible and mobile deployment. Utility Model Content
