Intercom system with audible and visual alarm function, and alarm method thereof

Abstract

The invention discloses an intercom system with an audible and visual alarm function, comprising at least two intercom devices, wherein each intercom device comprises: an intercom unit comprising a radio frequency transceiver circuit, a horn circuit, a microphone circuit, an antenna, an MCU control circuit and an interface circuit, the radio frequency transceiver circuit, the horn circuit, the microphone circuit and the interface circuit are electrically connected to the MCU control circuit, and the antenna is electrically connected to the radio frequency transceiver circuit; an alarm triggerunit electrically connected with the MCU control circuit and used for triggering and releasing alarm information; and an audible and visual alarm unit electrically connected with the MCU control circuit and used for emitting audible and visual alarm. According to the intercom system, the transmission of onsite alarm information can be achieved by the audible and visual alarm unit, and the alarm information can also be transmitted to other intercom devices to realize the remote transmission of the alarm information, thereby greatly improving the rescue efficiency.

Description

technical field [0001] The invention relates to the field of intercom equipment, in particular to an intercom system with sound and light alarm function and an alarm method thereof. Background technique [0002] The walkie-talkie is a two-way mobile communication tool that can talk without any network support. It is suitable for relatively fixed and frequent calls. At present, in fire emergency command and communication, firefighters must be equipped with walkie-talkies for voice communication; in addition, based on personal safety considerations, each firefighter will be equipped with a rescue device to initiate an alarm call for help in case of distress; these two devices are independent of each other. The rescue device realizes the local sound and light alarm. Existing rescue devices only have sound and light prompts, no communication function, and only the surrounding partners can recognize the call for help information. The information is transmitted only by sound and ...

AI Technical Summary

Problems solved by technology

Existing rescue devices only have sound and light prompts, no communication function, and only the surrounding partners can recognize the call for help information. The information is transmitted only by sound and light, and the transmission distance is limited. It is difficult for the commander to recognize the call for help information; at the same time, the information that can be transmitted by sound and light is limited , it is difficult to obtain the information of the person who issued the emergency call
