Convenient-to-deploy remote security and protection early-warning linkage system

Abstract

The invention discloses a convenient-to-deploy remote security and protection early-warning linkage system. The system comprises a plurality of induction front-end devices, a plurality of relay devices and a plurality of receiving-end devices; the induction front-end devices are in communication with the relay devices through a LoRa encryption protocol; a LoRa star topology network is established among the relay devices; the receiving-end devices are connected to the LoRa star topology network; the receiving-end devices are connected with a mobile phone APP through Bluetooth; and the relay devices and the receiving-end devices are subjected to working mode switching through a physical key or a key of the mobile phone APP. A traditional network architecture is abandoned; a LoRa star topology networking technology is adopted; a 433 Mhz wireless transmission frequency is achieved; a communication distance of more than or equal to 3 Km (sight distance) can be realized; and the system can be rapidly deployed in large-range places such as factories, parks and the like. Compared with high cost of deploying a network environment in large-range places by a traditional network-based security and protection early-warning system, the cost of a networking mode is low.

Description

technical field [0001] The invention relates to a security early warning system, in particular to a remote security early warning linkage system which is convenient for deployment. Background technique [0002] In the existing technology, the security early warning system is divided into two types, one is an early warning system based on infrared, human sensing and other sensors supplemented by the Internet of Things to realize the flow of people, and a video surveillance system supplemented by human or artificial intelligence early warning system. The front end of this type of security early warning system mostly uses mains power supply, relies on traditional wired and wireless network transmission protocol data, and uses PC and projection system as the display early warning terminal to form a general security early warning system. [0003] The existing problems in the security warning system are as follows [0004] 1. The front end of the traditional security warning (ca...

AI Technical Summary

Problems solved by technology

[0004] 1. The front end of the traditional security warning (camera lens, infrared sensor, etc.) is large in size and mostly exposed, which is not convenient for concealed deployment

[0005] 2. The traditional security early warning adopts the power supply mode of the mains and the traditional networking mode, which makes it more difficult to deploy, install and debug, and project costs

[0006] 3. The traditional security early warning system uses encrypted or non-encrypted network and cloud protocols. Due to the defects and loopholes of the network itself and the increasing development of hacker technology, the security of the traditional security early warning system is difficult to guarantee

[0007] 4. The traditional security early warning system relies on the traditional network transmission data protocol, and its anti-interference ability is poor. Once the network environment is paralyzed, it will lose the ability to prevent security and alarm

[0008] 5. Traditional security early warning systems rely on traditional network construction, which severely limits the deployment area and coverage of such security systems
