Description
Technical field
The utility model relates to electronics, communication field, relates in particular to a kind of single alert law enforcement and looks audio recording instrument and wireless single alert law enforcement Bluetooth talkback system.
Background technology
Bluetooth is a kind of low-power consumption, short-distance wireless communication technology.Bluetooth is as wireless communication standard among a small circle, and maximum advantage is exactly that electronic installation each other can the wireless connections by bluetooth, has saved traditional cable and has connected.
The standard of bluetooth is IEEE802.15, is operated in 2.4GHz ISM(industry, science, medical treatment) on frequency range, centre frequency is 2.45GHz, the user has saved application and has paid the trouble of frequency range cost of use.Yet also have the public identical frequency ranges of electronic equipment such as Wi-Fi, HomeRF and microwave oven, cordless telephone in the 2.4GHz frequency range, interference phenomenon is unavoidable in theory.For prevent with other equipment between the phase mutual interference, bluetooth has adopted the measure of a series of uniquenesses such as AFH AFH, power control, guarantees that so namely bluetooth communication avoids interference again other communications.
Single alert law enforcement of earliest period is looked the audio recording instrument and all is connected with intercom or Vehicle mounted station with wired mode, and such wired high expensive is worn, maintenance, dilatation be all more difficult.Afterwards, low cost prevailing gradually in industry is worn well, the wireless talkback mode of easy care.
Summary of the invention
The purpose of this utility model is to provide a kind of single alert law enforcement to look audio recording instrument and wireless single alert law enforcement Bluetooth talkback system, substitutes traditional wire communication mode by communication, reduces costs, and raising is worn, the simple and easy degree of maintenance and dilatation etc.
The purpose of this utility model is achieved through the following technical solutions.
The audio recording instrument is looked in a kind of single alert law enforcement, comprising enforces the law records PCBA, a PTT button, loudspeaker, law enforcement is recorded PCBA and is connected respectively with a PTT button, loudspeaker, also comprises bluetooth module, and this bluetooth module records PCBA and is connected respectively with a PTT button, law enforcement.
The alert law enforcement of a kind of wireless list Bluetooth talkback system comprises that intercom, single police enforce the law and look the audio recording instrument, also comprises Bluetooth adapter, and this Bluetooth adapter is built-in or be external in intercom, is connected with intercom;
The audio recording instrument is looked in described single alert law enforcement, and comprising enforces the law records PCBA, a PTT button, bluetooth module, loudspeaker, and law enforcement is recorded PCBA and is connected respectively with a PTT button, bluetooth module, loudspeaker, and a PTT button is connected with bluetooth module simultaneously;
Described intercom is looked the bluetooth module wireless connections of audio recording instrument by Bluetooth adapter and single alert law enforcement.
Wherein, also comprise bluetooth earphone and the 2nd PTT button, bluetooth earphone is connected, is connected with intercom by Bluetooth adapter with the 2nd PTT button.
Wherein, also comprise background PC computer, look audio recording instrument wired connection with single alert law enforcement.
Wherein, described intercom is Vehicle mounted station or hand transceiver.
Compared with prior art, the utility model embodiment has following beneficial effect:
Set up wireless blue tooth PTT function on the audio frequency law-enforcing recorder existing single alert looking in the utility model embodiment, can carry out wireless connections with hand transceiver, vehicle-mounted ride and other bluetooth equipment by the alert law-enforcing recorder of Bluetooth adapter list, having saved traditional cable connects, not only reduced cost, conveniently worn and safeguard, and compact conformation, the convenient use again small and exquisite, attractive in appearance, be easy to collection.
Description of drawings
