Protection.
Human-computer interaction module 5 can be switched in shadowless lamp, carry out between shutdown and standby mode state equipped with 3 keys
Switching can be adjusted to shadowless lamp brightness and support to pin the function that quickly increase and decrease and short-press increase and decrease brightness degree step by step, behaviour
Make simple and convenient.Human-computer interaction module 5 supports the customized setting to shadowless lamp brightness regulation mode, is touched and is shown by LCD
Screen 51 and key 52 operate, can the parameters such as brightness degree number to shadowless lamp and dimming scope set.Human-computer interaction
Module 5 is equipped with 53 transceiver of infrared remote control, control system can according to the infrared signal received, to shadowless lamp control system into
Row related setting and operation.LCD touch display screen 51 uses 1.8 cun of color liquid crystal touch display screens, and human-computer interaction module 5 passes through
Spi bus is communicated with control module 1, being capable of the current brightness degree of real-time display shadowless lamp, shadowless lamp king light 42 and nothing
The working condition of shadow lamp pair lamp 43.
The pcb board of control system in design using the technology of one point earth, by power unit and signal wire point when layout
It opens and thick using 2oz or more copper when applying copper, the impact and electromagnetic interference of current break is reduced with this.
As shown in Fig. 2, a kind of workflow of medical halogen shadowless lamp intelligence control system is as follows: when the power supply pipe of system
After reason module 2 powers on, control module 1 carries out Initialize installation first, is then shut off the backlight of LCD touch display screen 51, enters
Low-power consumption standby mode.When pressing the button the power button triggering interruption in 52, system is waken up while lighting LCD touch rapidly
The backlight and prompt system self-test, drive module 4 of display screen 51 open shadowless lamp king light 42 by driving metal-oxide-semiconductor 41.Shadowless lamp
When king light 42 works normally, system refreshes the state of LCD touch display screen 51 according to shadowless lamp present intensity, once detect nothing
Shadow lamp king light 42 breaks down, and closes king light power supply opening shadowless lamp pair lamp 43 immediately, automatic to carry out the switching of major-minor lamp and guarantee
Brightness is constant.While switching, LCD touch display screen 51 prompts current king light failure and asks whether to continue to use, and continues to make
With the state for then updating LCD touch display screen 51, without using then power-off shutdown, when inquiry, does nothing then system default
It continues to use.If shadowless lamp pair lamp 43 also breaks down in use, system if, can prompt maintenance circuit more to change the bulb,
The flashing alarm of LCD touch display screen 51.In entire shadowless lamp workflow, any time passes through the closing key in key 52 all
It can cut off the power immediately and manage the power supply of management module 2, to immediately close off shadowless lamp king light 42 and shadowless lamp pair lamp 43.
As shown in figure 3, a kind of medical halogen shadowless lamp intelligence control system, is made using the PWM output that frequency is 800Hz
Metal-oxide-semiconductor 41 is in high-frequency on off operating mode, realize shadowless lamp without stroboscopic operation.It, can be to nothing by changing the duty ratio of PWM
The brightness of shadow lamp carries out multistage smooth adjustment.As shown in figure 3, it reliably can be connected and drive when 41 gate leve voltage of metal-oxide-semiconductor is 12V
Dynamic shadowless lamp works, and first order triode plays the role of level translation in figure, when so that powered on moment I/O port being floating state
Metal-oxide-semiconductor 41 is not turned on, and prevents the flashing out of control of powered on moment shadowless lamp.In addition, triode, which forms push-pull output part, can improve MOS
The turn-off speed of pipe 41, and the capacitor at gate leve can be used to remove flash removed.
As shown in figure 4, medical halogen shadowless lamp intelligence control system detects shadowless lamp circuit using voltage comparator
Working condition.It is 0.01 Ω that power resistor R1 and R2 resistance value in shadowless lamp major-minor lamp performance loop is connected in Fig. 3, by its two
The voltage difference at end accesses voltage comparator as input terminal (L1+, L1- and L2+, L2-).When metal-oxide-semiconductor 41 is connected, resistance both ends
Pressure difference is greater than zero, and comparator exports high level, on the contrary then export low level.Electricity when being worked normally with PWM technology humanized shadowless lamp
Road is in high frequency on state, and comparator output terminal mouth can continuously export failing edge, and triggering is interrupted.Conversely, when fault then
Interruption will not be triggered.Control system is by can effectively judge shadowless lamp circuit to the continuous detection for interrupting trigger flag position
Working condition.
In the embodiment of the present invention, voltage difference when shadowless lamp works normally on 0.01 Ω inspection leakage resistance can generate variation, from
And detection trigger is interrupted, the state flag bit of set shadowless lamp.Referring to Fig. 5, in testing process, every 50ms to this mark
Will position is judged, if it is set, illustrates that shadowless lamp is working properly, is reset the waiting of this flag bit at this time and is examined next time
It surveys, it is on the contrary then illustrate that performance loop is abnormal.
Set of frequency when shadowless lamp works ensure that inspection so that interrupting and can repeatedly be triggered in single detection in 800Hz
The accuracy of survey.In order to further increase the reliability of detection, if this control system finds that state flag bit does not have when detecting
It is set, will do it secondary judgement, if the result judged twice is identical, illustrate that the lamp really belongs to malfunction, lead
Want process as shown in Figure 5.
