Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model mainly is based on following two kinds of technical foundation:
1) UWB (Ultra Wide Band, super bandwidth) technology is ripe gradually, UWB be a kind of frequency of operation several Hz between several GHz, bandwidth reaches as high as hundreds of Mbps, need not carrier wave, the emerging wireless communication technology that communicates by narrow pulse signal.The bright and clear gradually and standardization of UWB-Bluetooth technology, bluetooth organization planning issued UWB-Bluetooth protocol draft of future generation in 2008.After Bluetooth technology combined, UWB had had very large market in consumer electronics field, can become universal day by day.UWB can judge from the mistiming that sends to feedback whether target machine exceeds monitoring range by detection signal.
2) the new operating system of releasing requires notebook computer equipment after standby, sleep or shutdown, still can and can make its operate as normal to the wireless device power supply.Wireless device also can be monitored it under the state that notebook computer is not started shooting, guarantee the process safe that it is being carried.For example: the double-screen notebook based on Vista operating system SideShow technology, still can move wireless device after closing basic display unit.So-called SideShow is the new function that Vista operating system provides.Outside the main screen of computing machine, add second peripheral device that adopts small screen.The information of this peripheral unit on can synchronous computer under the situation (CPU, hard disk, fan are not worked) of computer shutdown, operates in mode quick, low power consumption, shows information such as calendar, e-mail, or multimedia is provided.According to the information that notebook manufacturer provides, if only open SideShow, the notebook computer with this function can support 140 hours.
Therefore, embodiment of the present utility model, can be implemented in notebook computer standby, sleep or shutdown after, the distance that can keep in communication and get in touch and judge notebook computer by UWB technology and notebook computer still, and, send alarm according to the distance of notebook computer.
The structural drawing of the bluetooth anti-theft device that Fig. 1 provides for the utility model embodiment, as figure, the bluetooth anti-theft device comprises: the super bandwidth radio-frequency chip 101, decision device 102 and the alarm 103 that are linked in sequence; Described super bandwidth radio-frequency chip keep super bandwidth communication to be connected with an electronic equipment, and the range information of the distance value between transmission described electronic equipment of representative and the described anti-theft device is to described decision device; Described decision device, send the described distance value of representative greater than the alerting signal of predeterminable range thresholding to described alarm; Described alarm is received output alarm sound signal after the described alerting signal.In addition, described decision device 102 also connect can regulate described distance threshold apart from controller 104.
Among the utility model embodiment,, can be notebook computer, mobile phone, PDA, PMP (Portable Media Player, portable electronic device), MP3 or MP4 player etc. with super bandwidth bluetooth communication function as the electronic equipment of antitheft object.
The bluetooth anti-theft device that the utility model embodiment provides can be to realize on the equipment of carrying and support the UWB-Bluetooth technology, for example, realizes on equipment such as bluetooth earphone, mp3 player.
Below introduce and how on bluetooth earphone, to realize anti-theft device of the present utility model.Fig. 2 is the structural drawing of common bluetooth earphone, the structural drawing of the antitheft bluetooth earphone that Fig. 3 provides for the utility model embodiment, with reference to figure 2, Fig. 3, antitheft bluetooth earphone is on the basis of original common bluetooth earphone, replaced the Bluetooth RF chip with super bandwidth radio-frequency chip, and increased decision device, alarm and apart from controller.Wherein, described alarm connects the audio process of described earphone, described alerting signal behind the audio codec of described audio process and described earphone, by the output of the loudspeaker of described earphone, two loudspeakers of working when loudspeaker can be for difference.Can set alarm distance by the lip-deep button of earphone, knob or slide key apart from controller.
The antitheft processing flow chart that Fig. 4 provides for the utility model embodiment.As figure, comprise the steps:
The user sets monitoring distance A in the distance controller;
Radio frequency chip detect and anti-theft device and target electronic device between apart from B;
Decision device compares judgement, if A>B does not report to the police; If A<B sends alerting signal to alarm;
Alarm sends the alert audio signal to loudspeaker after receiving alerting signal;
Loudspeaker is reported to the police.
In addition, if electronic equipment exceeds investigative range, super bandwidth radio-frequency chip sends the communicating interrupt signal to described alarm; Described alarm is exported described alert audio signal after receiving described look-at-me.
Below, for the application scenarios that this implementation is novel is given an example.
Scene 1: the user carries notebook computer and goes Waiting Lounge to wait, and notebook computer is locked in the storage tank.The utility model still can be realized the monitoring to notebook computer by the obstruct of UWB technology penetrating metal casing and building masonry wall.And based on traditional bluetooth, 802.11x, infrared wireless device such as grade are because penetration power and degree of accuracy are limited, and the application here is very limited.User of the present utility model can know that in enjoy music enjoyment the notebook computer of oneself is whether still in storage tank.
Scene 2: the user carry notebook computer by train (aircraft etc.) travelling the way in, can be relieved notebook computer is put on the shelf.The user wishes that notebook computer remains on apart from oneself distance of 1 meter, but based on traditional bluetooth, 802.11x, the infrared wireless device that waits is limited owing to precision, do not reach the range finding in 1 meter, very likely notebook computer has left bus (train etc.) and has just been found by the user.But use the utility model just can avoid this problem.
Scene 3: the user carries notebook computer and (also can be the vehicles such as taxi) by bus and when getting off, notebook computer may be forgotten onboard.Based on 1 meter the guard space that the user sets, when also not leaving motorbus, the user reminds the user, just can avoid this problem.
As from the foregoing, the utility model embodiment detects target electronic device by the radio-frequency module based on UWB and whether exceeds setpoint distance, and antijamming capability is strong, does not rely on network environment; Degree of accuracy with centimetre-sized can know accurately that equipment is whether among oneself is controlled; Penetration power is strong, the influence that not intercepted by body of wall; Have low emissive power and low energy consumption, and less transceiver volume, integrated with bluetooth earphone, do not change the bluetooth equipment host side, cost is low, and is more hidden.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
