Wireless vibration detecting and warning system

Abstract

The invention discloses a wireless vibration and detection alarm system, which comprises a wireless vibration and detection node and a 485 gateway node. The wireless vibration and detection node comprises a vibration signal detector, a RC filter, an A / D signal sampling module, an alarm signal processing module, a radio frequency control module I, and a radio frequency transceiver I, which are connected together in turn. The alarm signal processing module is also connected with a local alarm. The 485 gateway node comprises a radio frequency transceiver II, a radio frequency control module II, a serial data communication module II, a 485 drive circuit, and a 485 interface, which are connected together in turn. The radio frequency transceiver I is wirelessly connected with the radio frequency transceiver II, thereby realizing wireless signal communication between the wireless vibration and detection node and the 485 gateway node. The invention has the advantages that: the advanced wireless sensor network technology and the intelligent routing algorithm are adopted to realize automatic networking and remote control without special setups; a full duplex multi-hop routing mode is adopted in the data communication, thereby bringing about a large network capacity and a large covering surface; the invention overcomes the defects of great difficulty in system wiring, high maintenance cost, poor invisibility, vulnerability to damage, etc. in the prior detection system, thereby being adapted to harsh field environment.

Description

technical field [0001] The present invention relates to a technical field of safety precautions, specifically a vibration detection and alarm system that detects vibration shock signals to perform an intrusion anti-theft alarm, more specifically, a wireless sensor network technology is applied to detect vibration shock signals to perform Wireless vibration detection alarm system for intrusion burglar alarm. Background technique [0002] In recent years, with the development of my country's economy, people's quality of life has been continuously improved, and the accumulation of social wealth has reached a considerable level. Theft of national and personal property is on the rise. Cases of theft of banks, treasuries, museums, ancient tombs, guns and ammunition depots, personal residences, etc. occur from time to time, which brings great harm to the safety of national and personal property. Harm, although camera monitors are installed in some areas that need security protecti...
