Fire-special-use interphone

Abstract

The invention discloses a fire-special-use interphone, aims to provide the fire-special-use interphone with a more reliable security-call function or a self-help function, and solves the problem that when the fire is serious and the fire situation is complex, the requirement is difficult to be met, and the standby measures are deficient so that the situation in the fire can be obtained by command staff in time. The main point of the technical scheme of the invention is that the fire-special-use interphone comprises a shell and a circuit device arranged in the shell; the circuit device comprises an accidental alarm circuit and a talkback circuit; the accidental alarm circuit comprises an acceleration sensor used for sensing the shell speed, a control circuit connected with the acceleration sensor and used for performing signal processing, and a buzzer connected with the control circuit; and the control circuit judges the magnitude of the shell speed and controls the buzzer to give a strong sound alarm when the shell speed is less than a first speed value, and controls the buzzer to give a low sound alarm when the shell speed is greater than a second speed value.

Description

technical field [0001] The invention relates to a fire-fighting special walkie-talkie. Background technique [0002] At present, 350MHz-370MHz digital hand-held walkie-talkies are mainly used as the main communication equipment for fire rescue site command, which has played an active role in the actual rescue scene. However, there are still some problems with the handheld walkie-talkie communication methods currently used, mainly including: [0003] At present, the fire brigade mainly transmits messages by voice through digital handheld walkie-talkies. When firefighters are performing tasks, the fire scene is dangerous and chaotic, and they need to communicate with each other and issue instructions in a timely manner. It is also prone to accidents. If firefighters are in danger and cannot speak, they will not be able to communicate with the walkie-talkie. The situation will be very critical and they will not be able to call for help. [0004] The means of communication are ...

AI Technical Summary

Problems solved by technology

It is also prone to accidents. If firefighters are in danger and cannot speak, they will not be able to communicate with the walkie-talkie. The situation will be very critical and they will not be able to call for help.

[0004] The means of communication are too single, lack of backup communication methods. The fire rescue scene uses 350MHz~370MHz digital hand-held intercom communication equipment to conduct conventional voice communication. The communication power consumption is low and the coverage is limited. It is difficult to meet the requirements when the fire situation is serious and the fire scene is complicated. Backup measures enable the command personnel to obtain the situation in the fire scene in time
