Problems solved by technology

[0003] The purpose of the present invention is to overcome that the existing integrated walkie-talkie or forensic walkie-talkie occupies manpower resources and is inconvenient to use. The microphone and earphone of the walkie-talkie integrated with the Bluetooth microphone and the earphone are easy to be knocked off by the anti-law confrontation personnel and shouldered. The forensic shoulder microphone hooked by the loop will be pulled out by anti-law confrontation personnel. In conjunction with the invention patent "A Terminal Device for Audio-Visual Evidence Collection Intercom System" filed by the inventor at the same time, an audio-visual Evidence Forensic Intercom System Terminal is proposed , especially suitable for equipment configuration as an on-site evidence collection intercom tool for law enforcement officers

Embodiment 1

[0043] Such as figure 1 , 2 As shown in , 3, an audio-visual forensics intercom system terminal includes an earphone 1, an information collection head 2 and a host 3; the earphone 1 includes a speaker 11, an audio power amplifier module 12, a Bluetooth module A13, and a power circuit A14 And battery A15, battery B21, camera 22, microphone 23, audio-visual processing module 24, bluetooth module B25, LED lighting lamp 26 and power supply circuit B27 are set in the described information collection head 2, and voice Intercom module 33, main control module 34, satellite positioning module 36, memory 35, bluetooth module C32, power supply circuit 37 and battery C31,

[0044] The earphone 1 and the information collection head 2 are connected to the host 3 through wireless transmission signals;

[0045] The battery A15 of the earphone 1 is connected to the input end of the power circuit A14, and the output end of the power circuit A14 is respectively connected to the input end of th...

Embodiment 2

[0050] Such as figure 1 , 2 In the shown audio-visual position forensics intercom system terminal, the main control module 34 of its host computer 3 receives the on-site recording information from the information collection head 2 microphone 23, the on-site video information of the camera 22, and the satellite positioning module 36 received by the Bluetooth module C32. The positioning information corresponds to the system time generated by the clock chip of the main control module 34 and is stored in the memory 35 .

Embodiment 3

[0052] Such as figure 2 , 3 As shown in the audio-visual positioning intercom system terminal, the default working state of the voice intercom module 33 is voice playback, and the voice playback signal is transmitted to the bluetooth module C32 through the main control module 34 through the a playback channel and wirelessly sent to the earphone 1 for playback The microphone 23 of the information collection head 2 is not only an environmental recording microphone, but also a calling microphone for voice intercom; When the control module 34 receives the audio input information from the microphone 23 through the Bluetooth module C32 and contains the call password of the wearer, it transmits the voice call information of the microphone 23 to the voice intercom module 33 through the PTT call channel, and the voice intercom module 33 is played by the player. The mode changes to the call mode, and after the wearer stops calling for 3 seconds, the main control module 34 disconnects ...

Abstract

The invention relates to an audio-video-position evidence obtaining intercom system terminal which comprises an insert earphone, an information acquisition head and a host and is characterized in that the insert earphone and the information acquisition head are connected with the host by adopting wireless transmission signals; the information acquisition head is used for acquiring field audio and video information; a satellite positioning module of the host is used for acquiring field positioning information; the audio, video and position information is stored in a storage of the host by a main control module of the host; and a play or call state of a talkback voice module in the host is automatically controlled by the main control module of the host according to a call instruction of a wearer. The audio-video-position evidence obtaining intercom system terminal does not occupy hand of the wearer in the evidence obtaining and talkback process and is particularly suitable to use as necessary equipment for law-enforcement and duty personnel.

Description

Technical field [0001] The invention relates to an intercom system terminal for obtaining audio-visual evidence, which belongs to the wireless digital communication technology. Background technique [0002] Among the communication tools for police officers and other law enforcement personnel, the walkie-talkie is one of the basic information terminals configured. The traditional walkie-talkie must be held, called and listened to. It is necessary to press the switch PTT button and put the walkie-talkie directly to the caller’s mouth to make a call. On the bad side of disputes between French and French opponents. Therefore, a walkie-talkie with a Bluetooth microphone earphone has appeared, and the host can be worn on the belt around the waist or hung on the shoulder loop. However, the walkie-talkie of the Bluetooth microphone earphone may cause physical disputes or even fights with the anti-law confrontation personnel during the law enforcement process. As far as law enforc...
