Kind Portable Bluetooth control device.
The technical scheme is that：A kind of Portable Bluetooth control device, specifically includes control terminal circuit, the control terminal
Circuit includes：Bluetooth serial ports module, processor unit, switch, current-limiting resistance and pull-up resistor, wherein, switch is in normally opened shape
State, one end lotus root of switch are connected to ground potential, and the other end is connected with one end of pull-up resistor and the input pin of processor unit, blue
The TX pins of tooth serial port module are connected with the RX pins of processor unit, the RX pins of bluetooth serial ports module and processor unit
TX pins are connected, and the VDD pins of bluetooth serial ports module, the VDD pins of processor unit pass through current-limiting resistance and input voltage phase
Even.
Further, the control device further includes ornament, and the control terminal circuit is positioned over the ornament
It is interior.
Further, the processor unit is specially 51 microcontrollers.
Further, the input voltage is specially 3.3V.
Further, the ornament is specially brooch, button, job number board Kato or flexible paster.
Beneficial effects of the present invention：The Portable Bluetooth control device of the present invention can be realized to be interacted with smart machine, is
Smart machine increase can be by user-defined remote control function, for controlling smart machine；Control terminal circuit is positioned over dress

Brief description of the drawings
Fig. 1 is the control terminal electrical block diagram of the Portable Bluetooth control device of the embodiment of the present invention.
Fig. 2 is the controlled terminal of the embodiment of the present invention（Smart machine）Workflow schematic diagram.
Embodiment
The invention will be further elaborated with specific embodiment below in conjunction with the accompanying drawings.
The Portable Bluetooth control device of the present invention, specifically includes control terminal circuit, control terminal electrical block diagram such as Fig. 1
It is shown, including：Bluetooth serial ports module, processor unit, switch, current-limiting resistance R1 and pull-up resistor R2, wherein, switch is in normal
Open state, one end lotus root of switch are connected to ground potential, the other end and one end of pull-up resistor R2 and the input pin of processor unit
It is connected, the TX pins of bluetooth serial ports module are connected with the RX pins of processor unit, RX pins and the processing of bluetooth serial ports module
The TX pins of device unit are connected, the VDD pins of bluetooth serial ports module, the VDD pins of processor unit by current-limiting resistance R1 with
Input voltage is connected.
In the structure of fig. 1, processor unit is specially 51 microcontrollers, and the input voltage for its power supply is specially 3.3V.
In order to which beauty is convenient, control device here further includes ornament, and control terminal circuit is positioned in ornament.Decoration
Thing is specially brooch, button, job number board Kato or flexible paster.During specifically used, flexible paster can be attached to automobile
On steering wheel or bicycle handlebar on hand.
Here bluetooth serial ports module, matching unit is sent corresponding number when receiving serial data using antenna
According to；Microcontroller, takes charge of the explanation push button signalling, is construed to order and be sent to bluetooth serial ports module accordingly.
The main function of Portable Bluetooth control device according to the invention is by Bluetooth control smart machine（Intelligent hand
Machine）.
Specific work process is as follows：When controlling terminal circuit powered operation, button is in normally open, at this time due to pull-up electricity
The effect microcontroller input pin GPIO of resistance R2 is in high level；When a key is pressed, microcontroller input pin GPIO connects with ground
Logical, in low level, and the program by being run in microcontroller judges that button is short-press or long-press, if short-press, then passes through string
Mouth TX sends " 0 " to bluetooth serial ports module, bluetooth serial ports module is sent data " 0 " to matching unit by antenna；It is if long
Press, microcontroller sends " 1 " by serial ports TX to bluetooth serial ports module, bluetooth serial ports module is sent by antenna to matching unit
Data " 1 ".
Smart machine（Smart mobile phone）On software workflow it is as shown in Figure 2.Software is searched after starting and Auto-matching
Bluetooth equipment, circulation wait blue-teeth data is carried out after matching bluetooth equipment.If the blue-teeth data received is " 0 ", enable
Refusing incoming call function, i.e. rejection current call, and content is sent as the short of " being inconvenient to answer the call, contact with you later " to other side
Letter；If the blue-teeth data received is " 1 ", starts searching mobile phone function, i.e., mobile phone is arranged to outdoor pattern, and play sound
It is happy.
The specific implementation process and smart machine of above-mentioned microcontroller（Smart mobile phone）On software workflow can be considered existing
There is technology.
The contribution of the present invention is to provide a kind of Portable Bluetooth control device, by control device, by bluetooth, by existing
