Abstract

The invention discloses a wireless interphone intelligent control broadcasting system having a fingerprint identification function. The system includes a transmitting device and a receiving device, through the system, a user does not need to replace existing broadcast machine room equipment, and only needs to connect a wireless interphone emergency start receiving device to a broadcast machine room power supply, a pre-amplifier and a sound box, after the right of use is obtained through fingerprint identification authentication, start and stop of the broadcast machine room can be directly controlled through a human-computer interface and voice signals are transmitted to preset broadcast partitions. The system can identify user fingerprints, and distinguishes the authenticity of a holder, is high in confidentiality and economical and simple to realize, the response time is less than 3 seconds, and the system does not need a specially-assigned person for attending, and has functions of timely and reliable communication, effective command and efficient handling in sudden safety accidents.

Description

technical field

[0001] The invention relates to fingerprint identification technology, radio technology and microcomputer control technology, and is suitable for occasions where the broadcasting needs to be quickly started and the accident message is played to notify crowds to evacuate under emergency situations at the grassroots level such as schools, wharves and small and medium-sized enterprises. Background technique

[0002] In recent years, natural disasters, public health, and production safety accidents have occurred frequently in our country. For example, the 11.5 commercial building fire accident in Jilin City in 2010 caused 19 deaths, 31 injuries, and a direct economic loss of more than 50 million yuan. Therefore, the rapid response and timely release of emergency and disaster events are becoming more and more important. In the social public security system, the emergency command and communication system is an important link and basic guarantee of the emergency man...
