Wherein, man-machine interaction device 200 is specific realizes human-computer interaction in the form of button.
Controller 300 is for issuing corresponding control signal under the instruction of man-machine interaction device 200.
Wherein, for controller 300 specifically using serial 16 super low power consuming single chip processors of MSP430, which uses PWM
The transmission power of (Pulse Width Modulation, pulse width modulation) control laser beam.
Laser driving circuit 400 is connected, for the control with controller 300 and N number of single-point laser 100
Signal amplifies, and amplified control signal is used to control the switch state of N number of single-point laser.
Specifically, controller 300 handles the button event of user, and when user implements a certain button event, controller is
Control instruction corresponding with the button event is received, and corresponding control signal is issued according to button event control instruction,
The control signal controls the switch state of 5 single-point lasers after being amplified by laser driving circuit 400, to realize to five beams
Opening or closing for laser is controlled.
In the present embodiment, 5 single-point lasers are successively labeled as No. 5 No. 1 laser, No. 2 lasers ... lasers,
Following four kinds of open modes are provided with for 5 single-point lasers:
Mode a:1, No. 3, No. 5 lasers unlatchings；
Mode b:2, No. 4, No. 5 lasers unlatchings；
Mode c:1, No. 2, No. 3, No. 4 lasers unlatchings；
Mode d:1, No. 2, No. 3, No. 4, No. 5 lasers unlatchings.
And above four kinds of open modes are stored in order to as in the single-chip microcontroller of controller in advance, concurrently set default
Mode (mode d, i.e. 5 single-point laser all lights).When five dot lasers are switched to open by closed state, opened using default
Mode, later, user by button in single-chip microcontroller open mode carry out cyclic switching, when single-chip microcontroller receive user by
When button event, under the open mode control of five dot lasers is switched to present mode under the auxiliary of driving circuit by single-chip microcontroller
One mode.For example, it is assumed that the present mode of five dot lasers is mode a, when the user depresses the button, then single-chip microcontroller is by 5 points
The open mode of laser is switched to mode b, i.e., No. 2, No. 4, No. 5 lasers are turned on.It should be noted that push button function
And the regulation of laser open mode is not limited to above description, and personalized setting can be specifically carried out according to actual demand.
To sum up, since multiple spot laser provided in an embodiment of the present invention uses N number of single-point laser as multiple spot laser
N number of luminous point realize and issue N beam laser, and under the instruction of man-machine interaction device, pass through the control signal control that controller issues
The switch state of N number of single-point laser is made, opening or closing for N beam laser is controlled with realizing, N number of single-point laser hair
Laser beam out is not required to be sent by the optical system being made of reflecting mirror, prism etc., required N number of single-point laser
Existing single-point laser specifically can be used.As it can be seen that the present invention has evaded existing five dot laser due to raw using optical system
At five required luminous points, and pass through drawback caused by the transmission of optical system progress laser beam, instrument (multiple spot laser
Device) the internal verifying for being not required to optical system, therefore present invention reduces multiple laser beams to generate, the workload of control, accelerates
Design cycle, reduce development and production cost.
