At present, on the market the control mode of occurred camera head mainly has following three kinds：The first is manually to control shutter to be controlled；Second is controlled by remote control；The third is controlled by way of time-lapse photography, but above-mentioned three kinds of control modes are required for operator to be operated manually or are timed setting in advance, using inconvenience.
In prior art, though there is some brain wave control devices, these devices are mainly made up of visual stimulator, PC and the part of brain wave sample circuit three, there is volume larger, it is with high costs, the problems such as not readily portable, it is only suitable for laboratory research, it is impossible to suitable for daily life.The patent of Application No. 201220370838.6 discloses a kind of brain electric control camera device, described camera device, including carrier, photographic head, brain electric transducer, processor and memorizer, brain electric transducer includes at least one sensor group, eyes lower limb and picture frame are arranged at, are shot for the image of user " thinking in subconsciousness important ".The problem that the brain electric control camera device of this kind of technical scheme is present is：To reach the effect of precise control, it is necessary to gather brain wave, relatively costly, complex structure by multiple sensor groups；Shot mainly for the image of user " thinking in subconsciousness important ", it is impossible to fully achieve and shot by " subjective consciousness " control photographic head；There is no flash lamp, it is impossible to carry out shooting at night.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of shooting head hoop controlled based on brain wave, its simple structure, small volume, is easy to carry and easy to operate, can simplicity on-off control is carried out to photographic head.
The technical solution adopted in the present invention is：A kind of shooting head hoop controlled based on brain wave is included：Head hoop body（1）, controller（2）, flash modules（3）, camera module（4）, optical sensor module（5）, power module（6）, memory element（7）, brain wave collector（8）.
Described controller（2）Using 32 low-power consumption microcontroller STM32C8T6 chips as control core, the corresponding hardware circuit of periphery configuration realizes systemic-function.
A kind of brain wave collector of described shooting head hoop controlled based on brain wave（8）For TGAM modules, using NeuroSky ThinkGear brain wave chips, TGAM modules include the electrode extracted to the EEG signals of user to described TGAM modules（8-1）With the electrode extracted to EEG signals（8-1）Carry out the EEG signals pretreatment unit sampled with pretreatment（8-2）, described EEG signals pretreatment unit（8-2）With electrode（8-1）It is connected, for collection analysises user real-time brain wave data.
Described flash modules（3）Including a LED and its peripheral circuit composition, for optical sensor detect ambient light it is gloomy when, open flash lamp increase intensity of illumination.
Described optical sensor module（5）Using numeric type light intensity sensor BH1750fvi, for detecting the intensity of illumination of environment.
The present invention has compared to existing technology advantages below：
1st, small volume, is easy to carry, low cost, and wearing mode is easy；
2nd, by brain wave collector, the control instruction of user is recognized using brain wave, liberates the both hands of user, practicality is high；
3rd, intensity of illumination is detected by optical sensor, realizes the function that flash lamp in grey dark situation automatically turns on illumination.

Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described with example.
As shown in Fig. 2 a kind of shooting head hoop controlled based on brain wave includes head hoop body（1）, it is characterised in that：Head hoop body（1）It is provided with controller（2）, controller（2）Two signal input parts respectively with optical sensor module（5）And brain wave collector（8）It is connected, controller（2）Two signal output parts respectively with flash modules（3）And camera module（4）It is connected, memory element（7）With controller（2）It is connected, head hoop body（1）It is provided with and controller（2) connected power module（6）.
As shown in figure 3, the controller of the present invention is 32 low-power consumption microcontroller STM32C8T6 chips, as the control core of whole system.
As shown in Figure 4, described optical sensor module（5）Using numeric type light intensity sensor BH1750fvi, for detecting the intensity of illumination of environment, the light detection range of BH1750fvi is 0～200Klux.
A kind of described shooting head hoop controlled based on brain wave can be acquired and be processed by the EEG signals to user, realize the on-off control to photographic head.User is when using the head hoop, by the electrode in the brain wave collector of forehead front end come the brain wave data of Real-time Collection user, send data to the TGAM modules in brain wave collector, under the process of TGAM modules, miscellaneous eeg signal is converted into into a focus numerical value, its size is represented with 1 to 100.Next focus numerical value is sent to controller, there is the threshold value of switch photographic head in controller, as focus ＞ 60, photographic head is opened, during focus ＜ 20, photographic head is closed.When the optical sensor in head hoop detect ambient light intensity it is weaker when, would automatically turn on flash lamp, increase ambient lighting degree, there is provided good imaging environment.
