Device processed is realized.This kind of light source controller realizes that intensity of illumination controls by PC ends in the prior art, and function is complex；System
Power down store function is not done, unexpected power down cannot recover the intensity of illumination before power down after restarting；Therefore, application is not suitable for
In the low and middle-end visual field that some cost requirements are stringent, easy to operate, in addition this kind of light source controller circuit is using fixed electricity
Press the type of drive of output, it is necessary to coordinate corresponding light source that could work normally.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of robot vision light with power down storage
Source control system.
To achieve these goals, the technical solution adopted by the present invention is：A kind of robot vision light-source control system, bag
Light source driver module, master controller, display are included, it is strong to further include intensity of illumination knob adjustment module, power down memory module, illumination
Acquisition module is spent, the intensity of illumination knob adjustment module sends control signal to light source driver module, and the light source drives
Dynamic model root tuber exports corresponding drive signal according to the control signal control of reception and drives light source load；The intensity of illumination acquisition
The control signal of the output of module acquisition intensity of illumination knob adjustment module is simultaneously sent to master controller, the master controller point
A memory module and display Lian Jie not fallen.
The master controller quantifies intensity of illumination according to the signal that the intensity of illumination acquisition module of reception gathers
And grade distinguishing is carried out, the controller quantifies the intensity of illumination grade after distinguishing for real-time display.
The intensity of illumination knob adjustment module is potentiometer, and the knob of the potentiometer is by controlling light source to drive
The reference voltage of module controls the duty cycle of the output control signal of light source driver module.
The intensity of illumination acquisition module gathers the reference voltage of light source driver module to quantify to intensity of illumination,
And distinguish grade.
The master controller On-Chip peripheral includes ADC module, serial ports, SPI communications, and the master controller passes through SPI
Communication is connected with the communication of power down memory module, and the information such as the quantification gradation are write ferroelectric memory；On master controller
ADC module is acquired the reference voltage of light source driver module, for quantifying to intensity of illumination；The master controller
Display is connected by serial ports, for display to be controlled to be shown.
The advantage of the invention is that：Set a memory module, data when can store power down automatically after a power failure are simultaneously
Data are read when powering on and are shown；Can show intensity of illumination grade, and be stored in power down storage in, can after the power-up,
Immediately the light levels information before display acquisition power down and after power down is passed through；Its drive module can adaptively be born in the range of dynamic
Output is carried, its reference voltage is adjusted by potentiometer to realize the control of different intensities of illumination, load circuit has more
Alternative, the scope of application is wider；It is easy to operate using knob regulating illumination intensity, it is cheap.
Description of the drawings
Below to each width attached drawing of description of the invention expression content and figure in mark be briefly described：
Fig. 1 is light-source control system structure principle chart in the embodiment of the present invention.
Specific embodiment
Below against attached drawing, by the description to optimum embodiment, the specific embodiment of the present invention is made further detailed
Thin explanation.
Potentiometer adjusts the reference voltage of light source driver module, so as to which light source driver module be controlled to export corresponding duty cycle
Signal driving light source load, the ADC module on master controller is acquired the reference voltage of light source driver module, for pair
Intensity of illumination is quantified；Master controller On-Chip peripheral includes ADC module, serial ports, SPI communications, and master controller is communicated by SPI
It communicates and connects with power down memory module, and the information such as the quantification gradation are write into ferroelectric memory；Master controller passes through serial ports
Display is connected, for display to be controlled to be shown.
As shown in Figure 1, the invention mainly comprises master controller, light source driver module, potentiometer knob, LCD show, iron
Electricity, light source load.Master controller uses TI super low power consuming single chip processor MSP430F6459, is mainly included using its On-Chip peripheral
ADC, serial ports, SPI communications；It is a high-performance, super low power consuming single chip processor, the fever of control system can be reduced.
Light source driver module using DC DC power supply technology, fixed PWM wave Frequency Patterns output, light source driver module uses
High efficiency, the size of Linear Tech be small, loaded self-adaptive driving chip, model LT-3922 chips, and potentiometer knob passes through
The reference voltage of control light source driver module achievees the purpose that control light source driver module output duty cycle, so as to reach to light source
Intensity is controlled；
ADC module on master controller realizes the acquisition to the reference voltage, and intensity of illumination is quantified, so as to
Distinguish the grade of current light intensity；SPI is responsible for communicating with ferroelectricity, and the information such as quantification gradation write-in ferroelectricity is stored
Device；Ferroelectric memory is used to ensure that system in unexpected power-off, can preserve current light source strength grade information in time；LCD is responsible for
Real-time display current light intensity and the intensity of illumination before last time power down；
Light source controller system after the power is turned on, SPI equipment will read ferroelectric memory on intensity of illumination grade, ADC module
Also the reference voltage that will be set under reading potential device knob current state, being quantized into after intensity of illumination grade all will be real by LCD
When show, timing acquiring reference voltage, LCD also by the current illumination intensity information of periodic refreshing, are worked as system power failure by ADC module
When, can current light intensity be write by ferroelectricity by SPI modules in time, to be recovered after the power is turned on again.
