Fire automatic alarming system based on LORA wireless communication and method thereof

Abstract

The invention discloses a fire automatic alarming system based on LORA wireless communication and a method thereof. The system comprises a master control system, fire detecting equipment, alarm equipment, a firefighting executing device and an LORA wireless communication network. The fire detecting equipment is used for monitoring a fire signal and transmits a fire signal to the master control system. After the master control system receives the fire signal, the master control system transmits an alarm signal to the alarm equipment, and simultaneously the master control system transmits a firefighting control signal to the firefighting executing device. After the alarm equipment receives the alarm signal, the alarm equipment notifies a user of a fire alarm condition in a manner of transmitting a high-strength sound-and-light alarm signal. The firefighting executing device makes field executed firefighting equipment perform fire extinguishing according to the firefighting control signal. According to the fire automatic alarm system and the method thereof, LORA wireless communication technology is utilized, thereby truly realizing an alarming and firefighting linkage function of an existing wired firefighting automatic alarm system, and preventing defects of complicated wiring, many difficulties in manual mounting and complicated maintenance in a wired fire automatic alarm system.

Description

technical field [0001] The invention relates to the technical field of fire monitoring, in particular to an automatic fire alarm system and method based on LORA wireless communication. Background technique [0002] The existing automatic fire alarm system is generally designed and developed according to the three major system standards of American standard, European standard and national standard. The current product standards are all designed and developed according to the wired automatic fire alarm system. The wireless automatic fire alarm system has no clear standards and market access. However, with the development of wireless communication technology, more and more standardization organizations have begun to realize that wireless has gradually invaded the fire prevention and control market with an unstoppable momentum. The revised standard (EN14604) has added requirements on the RF part, but it will take two years for the current standard to enter the market from revisi...

AI Technical Summary

Problems solved by technology

[0007] 1. The existing wired automatic fire alarm and linkage system uses wired transmission for communication. The communication method determines that it requires complex wiring and installation of embedded boxes, which requires a lot of manpower and material costs, and long-distance wired transmission. power loss, and when the system fails, troubleshooting takes a long time, and the efficiency of troubleshooting is extremely low

[0008] 2. Most of the existing wireless fire alarm systems use narrow-band wireless communication technology in their communication methods, and in order to obtain market access, their implementation standards determine that they cannot achieve linkage control functions. The applicable occasions are only suitable for household use, especially for hosts that can carry The number of load points is insufficient, the communication distance is about 200 meters, and the farthest is 1000 meters. The cost of long-distance transmission is high
