Description
Technical field
The bluetooth headset that position and temporal information are sent the present invention is based on a key refers to a kind of bluetooth headset, especially
One kind sending personnel location information, real time position in the case of no network by one key of Big Dipper short message, is rescued for urgent feelings
Help the bluetooth headset used.
Background technology
Bluetooth is a kind of short-distance wireless communication specification of inexpensive large capacity, and bluetooth headset is exactly by Bluetooth technology application
In hands-free headsets, allow user that can exempt impeding for irritating electric wire, the easily call in various ways of comfortable ground.Bluetooth technology
It is global open, there is compatibility well, the whole world can be connected by the invisible bluetooth network of low cost in the world
Integrally.It has been always the good tool and people's daily life of Mobile Commerce race raising efficiency since bluetooth headset comes out
In common portable equipment.
Positioning system occupies increasingly heavier ratio in our life, and mobile phone can be used in the case where there is network
Send the location information of GPS, it is easy to the position for finding oneself, in the case of no network signal or communication condition difference,
The region that such as virgin forest, desert, depopulated zone are not covered with without network, or when going abroad, mobile phone card cannot make
Used time is occurred the natural calamities such as earthquake, tsunami and causes communication disruption, how quickly sent using portable common equipment
The location information of oneself, so that friends and family can grasp the position of oneself at any time or can in time will be real-time when needing emergency relief
Location information is sent to rescue worker, realizes without the positioning service under network state.
With the development of science and technology, Bluetooth technology has been popularized in more and more mobile phone vendors commercial city, while wireless is again that prevalence becomes
Gesture, its convenience, the advantage of various aspects are obvious.Current only Bluetooth technology can realize the wireless speech with mobile phone
Communication function, bluetooth headset is surmounting the main product that wired earphone becomes market, while bluetooth headset can become intelligence
Change.But at present not may be implemented still that position and the bluetooth headset of temporal information function can be sent at any time can make for masses
With the effective technology not also being worthy to be popularized can realize above-mentioned function.
Invention content
In place of against the above deficiency, a kind of indigo plant sending position and temporal information based on a key is provided
Tooth earphone uses big-dipper satellite location technology and Big Dipper short message communication technology, can wireless public network coverage hole, occur from
A real-time key sends positioning in the case that right disaster wireless public network interrupts, and realizes the tracking of real time position and rescuing for emergency
It helps, effectively promotes the speed of rescue.
The present invention takes following technical scheme to realize：
Based on a key send position and temporal information bluetooth headset, including bluetooth module, power management module, big dipper module,

Without using in the case of can close the power switch of big dipper module, only open the power switch of bluetooth headset, use bluetooth
Function saves electricity consumption.It is worth noting that the function that a key sends position and temporal information is needed to open simultaneously big dipper module and is opened
Position and temporal information could be sent by closing and pressing next key send key, need to use externally fed at this time, bluetooth headset itself
Battery cannot provide the high current of required 2A when sending a key location information, and externally fed can use and carry Type-C interfaces
Mobile phone either Portable power source.
Switch control flow includes the following steps：
1）Bluetooth headset master switch is opened, that is, opens bluetooth headset basic function；
2）There are other switch motions, then detects whether to switch for big dipper module；It is switched if it is big dipper module, then opens Big Dipper mould
Block works；It is switched if not big dipper module, then enters step 3）；
3）It detects whether to send for a key and switch；It sends and switchs if it is a key, then enter step 4）；It is sent if not a key
Switch then illustrates detection error, enters step 2）Again it detects；
4）Whether detection big dipper module switch is opened, if big dipper module switch is opened, opens a key and sends switch, can implement one
Key sends position and temporal information；If big dipper module switch is not turned on, user is prompted then to open big dipper module switch.
The present invention is in use, open bluetooth headset master switch, you can Bluetooth function is used, when there is other actuation of keys,
It checks whether the switch for big dipper module, is to open big dipper module power supply, bluetooth headset can receive to come from the Big Dipper in real time at this time
Otherwise the prompt message of satellite system checks whether that one key of position sends switch, if it is not, then illustrating to malfunction, needs to sentence again
It is disconnected, it is to check whether the power switch of big dipper module is opened, is, externally fed is connected to 5V power supplys by the USB of Type-C
On, it is powered to big dipper module by outside, a key sends position and temporal information is available, and big dipper module electricity please be beaten by not being voice prompt
Source, a key send switch and could work in the case of big dipper module power supply opening.
