Power pack using the technology of one point earth, is divided with holding wire during layout by the pcb board of control system in design
Open and adopt more than 2oz copper thickness, the impact that current break is reduced with this and electromagnetic interference in deposited copper.
As shown in Fig. 2 a kind of workflow of medical halogen shadowless lamp intelligence control system is as follows：Power supply pipe when system
After electricity in reason module 2, 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 pattern.When the triggering of the key in 52 that pushes button is interrupted, system is waken up to be lighted rapidly LCD simultaneously and touches
The backlight of display screen 51 prompt system self-inspection, drive module 4 is passed through to drive metal-oxide-semiconductor 41 to open shadowless lamp king light 42.Shadowless lamp
During king light 42 normal work, system refreshes the state of LCD touch display screen 51 according to shadowless lamp present intensity, once detecting no
Shadow lamp king light 42 breaks down, and closes king light power supply opening shadowless lamp pair lamp 43 immediately, automatically carries out major-minor lamp and switch and ensure
Brightness is constant.While switching, LCD touch display screen 51 is pointed out current king light fault and is asked whether to be continuing with, and continues to make
With then updating the state of LCD touch display screen 51, do not use then power-off shutdown, during inquiry, do not carry out any operation then system default
It is continuing with.If shadowless lamp pair lamp 43 also breaks down in use, system then can point out maintenance circuit more to change the bulb,
LCD touch display screen 51 flicker is reported to the police.In whole shadowless lamp workflow, any time is by the closing key in button 52 all
The power supply of management management module 2 of can cutting off the electricity supply immediately, thus 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, made using the PWM output for 800Hz for the frequency

The brightness of shadow lamp carries out multistage smooth adjustment.As shown in figure 3, when metal-oxide-semiconductor 41 gate leve voltage is 12V, it can reliably turn on and drive
The work of dynamic shadowless lamp, in figure first order audion plays the effect of level translation so that when powered on moment I/O port is floating state
Metal-oxide-semiconductor 41 is not turned on, and prevents the flicker out of control of powered on moment shadowless lamp.Additionally, audion forms recommending output mode part can improve MOS
The turn-off speed of pipe 41, and the electric capacity at gate leve can be used to flash removed.
As shown in figure 4, medical halogen shadowless lamp intelligence control system to detect shadowless lamp circuit using voltage comparator
Working condition.Being connected on power resistor R1 in shadowless lamp major-minor lamp performance loop and R2 resistance in Fig. 3 is 0.01 Ω, by its two
The voltage difference at end accesses voltage comparator as input (L1+, L1- and L2+, L2-).When metal-oxide-semiconductor 41 turns on, resistance two ends
Pressure reduction is more than zero, and comparator exports high level, otherwise then exports low level.With electricity during PWM technology humanized shadowless lamp normal work
Road is in high frequency conducting state, and comparator output terminal mouth can continuously export trailing edge, and triggering is interrupted.Conversely, during fault then
Interruption will not be triggered.Control system is passed through can effectively judge shadowless lamp circuit to the continuous detection interrupting trigger flag position
Working condition.
In the embodiment of the present invention, the voltage difference that during shadowless lamp normal work, 0.01 Ω examines on leakage resistance can produce change, from
And detection trigger is interrupted, the state flag bit of set shadowless lamp.Refer to Fig. 5, in testing process, every 50ms, this is marked
Will position is judged, if it is set, illustrates that shadowless lamp is working properly, now resets the wait of this flag bit and examines next time
Survey, otherwise then explanation performance loop is abnormal.
Frequency configuration during shadowless lamp work is in 800Hz so that interruption can repeatedly be triggered it is ensured that examining in single detection
The accuracy surveyed.In order to improve the reliability of detection further, if in detection, this control system finds that state flag bit does not have
It is set, secondary judgement can be carried out, if the result judging twice is identical, illustrate that this lamp really belongs to malfunction, its master
Want flow process as shown in Figure 5.
