Embodiment Construction

[0020] The present invention proposes an interactive wireless fire alarm system, which is described in detail in conjunction with the drawings and embodiments as follows:

[0021] The present invention proposes an interactive wireless fire alarm system whose structure is as follows: figure 1 shown. This system includes n wireless probes, 1 wireless video node and user mobile phone, n is a positive integer; among them, the wireless probe is networked through a short-distance wireless communication protocol (such as Zigbee protocol), and establishes a connection with the wireless video node, and the wireless video The node establishes a connection with the user's mobile phone through a public long-distance communication network (such as a WCDMA network); the wireless probe is used to realize the preliminary identification of the fire alarm; the wireless video node is used to send the received wireless probe information to the user, and the wireless probe alarm Take photos at an...

Abstract

The invention relates to an interactive type wireless fire disaster alarm system belonging to the field of wireless monitoring and comprising n wireless probes, one wireless video node and one user mobile phone, wherein the n wireless probes carry out networking through a short-distance wireless communication protocol and are connected with the wireless video node; the wireless video node is connected with the user mobile phone through a public long-distance communication network; the wireless probes are used for initially identifying fire alarm; and the wireless video node is used for sending received wireless probe information to a user, taking a picture to be sent to the user mobile phone when the wireless probes alarm or taking the picture to be sent to the user mobile phone according to a user command. The invention realizes the convenient installation of the system by combining a short-distance wireless communication technique and a long-distance wireless communication technique, enhances the usability of the system in such a way of linking the wireless probes and the wireless video node and shortens the responding time of accidents in an automatic detection and long-distance manual verification way.

Description

technical field [0001] The invention belongs to the field of wireless monitoring, in particular to wireless communication technology and fire monitoring technology. Background technique [0002] The existing fire alarm system (FAS, Fire Alarm System) mainly uses sensors such as smoke, temperature, video, image, and CO concentration or a combination of such sensors for fire discrimination, but false alarms and missed alarms are still the main problems of fire alarm systems. An important problem in the application, false alarms will cause unnecessary losses, so the fire alarm system used in the current building is generally separated from the building management system, and after the fire detection probe alarms, the management personnel need to go to the scene to confirm, the processing flow Increased costs and affected the speed of handling accidents. Although cameras are widely used in existing security systems, the cameras have not fully covered the fire monitoring area, an...
