Emergency command and distress call alarm device and system

Abstract

The invention discloses an emergency command and call-for-help alarm device and system, and in one specific embodiment, the device comprises a mobile command terminal; the plurality of intelligent terminals are arranged in a building, each intelligent terminal comprises a wireless ad hoc network module, a microphone and a microcontroller, and in a networking mode, the plurality of intelligent terminals respond to a networking instruction from the mobile command terminal to form a wireless ad hoc network through the respective wireless ad hoc network modules; in the emergency mode, a user mobile terminal of a call-for-help user in a building joins in the wireless ad hoc network; the microcontroller of each intelligent terminal obtains the position information of the call-for-help user relative to the intelligent terminal and sends the position information to the mobile command terminal; the microphone collects sound information of the call-for-help user and sends the sound information to the mobile command terminal; and the mobile command terminal presents the position information and the sound information.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things and wireless communication of edge computing, and more specifically, relates to an emergency command and call for help alarm equipment and system. Background technique [0002] In the traditional emergency broadcasting system, there are usually emergency speakers on each floor, which are concentrated in the central computer room for unified management through fixed lines. When earthquakes, floods, fires or other disasters strike, the fixed line facilities may be destroyed. unable to work properly. At this time, management personnel must be stationed in the central computer room to broadcast, and mobile emergency command cannot be realized; under the extreme conditions of "circuit break, power failure, and network disconnection", the fixed line may be broken, and the speakers fixed on each floor cannot Perform normal work, which in turn affects the evacuation and evacuation of u...

Problems solved by technology

[0002] In the traditional emergency broadcasting system, there are usually emergency speakers on each floor, which are concentrated in the central computer room for unified management through fixed lines. When earthquakes, floods, fires or other disasters strike, the fixed line facilities may be destroyed. unable to work properly

At this time, management personnel must be stationed in the central computer room to broadcast, and mobile emergency command cannot be realized; under the extreme conditions of "circuit break, power failure, and network disconnection", the fixed line may be broken, and the speakers fixed on each floor cannot Perform normal work, which in turn affects the evacuation and evacuation of users calling for help; the current emergency broadcasting system on the market is usually a one-way audio broadcasting, which cannot realize the collection of distress information, nor can it obtain the distress information with location

[0003] The existing traditional communication is based on the central server. When the central server is disconnected for some reason, the terminals of the entire network will be paralyzed and unable to operate, which cannot meet the shortage of performance in emergency broadcast communication; when calling for help When personnel do not carry communication equipment or have no base station signal, they cannot effectively communicate with the outside world; nor can they obtain the location information of the person calling for help
