Acousto-optic synchronous wireless fire safety evacuation equipment

Abstract

The invention discloses acousto-optic synchronous wireless fire safety evacuation equipment. The equipment at least comprises a plurality of single machines which are wirelessly networked with a central control device, wherein each single machine is in signal connection with a temperature detection device and a smoke detection device respectively; the single machine at least comprises a network wireless transmitting and receiving module, a program control board and a laser generation and control device; the laser generation and control device is used for providing a laser guide pattern and at least comprises a laser generator and a lens which is driven by a step motor; a replaceable pattern card is arranged between the laser generator and the lens; and the single machine also comprises an audio play device. The acousto-optic synchronous wireless fire safety evacuation equipment of the invention realizes intelligent system linkage and active indication, greatly improves the safety standard, reduces the possibility of casualties, has high industrial generalization capacity and has the advantages of many nodes, flexible allocation, high adaptability and high reliability.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a wireless fire-fighting safety guidance device with sound and light synchronization. Background technique [0002] At present, when abnormal fire conditions occur in public places, the existing technology basically stays in the use of passive equipment such as photoluminescent signs and emergency lights, and lacks intelligent dynamic guidance equipment with certain initiative. In the event of fire and other fire accidents, it is likely to cause casualties due to untimely evacuation. [0003] Laser technology is introduced into personnel guidance equipment, such as Chinese utility model 00254794.5 discloses a laser escape indicator device, utility model 200520042517.3 discloses a fire emergency light with a laser indicator, utility model 200720076169.0 discloses a fire emergency Laser guides, etc. However, the existing laser technology and corresponding products...

AI Technical Summary

Problems solved by technology

However, in the practical application of this invention, the power consumption is large, and the reliability of system information transmission is low.

In particular, this technology has the disadvantage that the number of nodes on the bus is limited (the bus can only support up to 128 node devices)

If it is to be applied in large-scale or super-large shopping malls, office buildings and other buildings, it is necessary to set up multiple hosts at the same time to meet the demand for a large number of nodes. This will cause high equipment investment costs, long communication lines, and many on-site interferences, which will bring management problems. Difficulty increases and management efficiency decreases, resulting in low communication reliability and stability, resulting in the failure to guarantee the operation quality of the networked system
