Abstract
The invention discloses a temperature control touch type high brightness LED (Light Emitting Diode) industrial X-ray film viewer, comprising an MCU (Micro-programmed Control Unit) control board, wherein the MCU control board is connected with a power module and a clock module; the input end of the MCU control board is connected with a temperature sensor, a touch board and a pedal switch; the output end of the MCU control board is connected with a fan and an LED drive circuit; and the LED drive circuit is connected with an LED array. Compared with the prior art in which a potentiometer is used for switching, the temperature control touch type high brightness LED industrial X-ray film viewer adopts a touch technique for switching, so that press keys are attractive, the film viewer is durable, and the defect that the potentiometer is damageable is overcome; and moreover, the response is quick due to the touch technique.
Description
Technical field
The present invention relates to the X ray viewbox that a kind of Non-Destructive Testing industry is used, be specifically related to a kind of temperature control touch-type X ray viewbox.
Background technology
Most widely used in the Non-Destructive Testing industry is ray detection method, and viewbox then is one of equipment the most frequently used in the ray detection.Potentiometer control 555 output PWM duty light modulations are recently adopted in light modulation more in the tradition viewbox, and the long-time light modulation of potentiometer damages easily, causes viewbox weak point in serviceable life, it is frequent to keep in repair; Even and traditional viewbox short time work fan also will rotate, energy consumption is many, noise is big.
Summary of the invention
The technical matters that the present invention will solve is that existing viewbox is fragile, and a kind of temperature control touch-type high-brightness LED industrial X-ray viewbox of long service life is provided.
Technical scheme of the present invention realizes in the following manner: a kind of temperature control touch-type high-brightness LED industrial X-ray viewbox; Comprise the MCU control panel; The MCU control panel links to each other with clock module with power module; The input end of MCU control panel links to each other with temperature sensor, touch pad and foot-switch, and the output terminal of MCU control panel links to each other with fan, led drive circuit, and led drive circuit links to each other with led array.
Said temperature sensor is the DS18B20 temperature sensor.
Said touch pad is a capacitive type touch pad.
Compare with potentiometer light modulation of the prior art, the present invention adopts the touching technique light modulation, and its button is attractive in appearance, durable in use, has overcome the perishable shortcoming of potentiometer, and the touching technique reaction is relatively quicker.

Embodiment
Shown in accompanying drawing; A kind of temperature control touch-type high-brightness LED industrial X-ray viewbox; Comprise the MCU control panel, the MCU control panel links to each other with clock module with power module, and the input end of MCU control panel links to each other with temperature sensor, touch pad and foot-switch; The output terminal of MCU control panel links to each other with fan, led drive circuit, and led drive circuit links to each other with led array.
Said temperature sensor is the DS18B20 temperature sensor.
Said touch pad is a capacitive type touch pad.
Among the present invention
Light modulation, speed governing and pattern control are by MCU control,The PWM (width modulation) of start control led drive circuit, this moment dutycycle fix, can not light modulation; Entering manual work pattern, dutycycle become 55% when touching touch pad; Can touch touch pad UP and DOWN button adjusting LED light intensity this moment; Dutycycle is fixedly got back to the initial set value light intensity and is fixed when touching touch pad once more, and light intensity is got back to setting value last time when getting into manual work pattern for the second time; When stepping on foot-switch, get into foot-operated pattern; Foot-operated mode prioritization level is the highest; As long as the foot-operated pattern of riding that gets into immediately, this moment, dutycycle became 55%, can touch UP and DOWN button and regulate the LED light intensity; Dutycycle is got back to the initial set value light intensity and is fixed when foot-operated unclamping, and light intensity is got back to setting value last time when getting into foot-operated pattern for the second time; The temperature that separated a period of time is gathered a LED heat radiator in entire work process; Radiator fan begins to rotate when temperature is higher than setting value; Level of rotation speed of the fan raising is inferior at interval in one of the every rising of temperature, up to the fan full-speed operation, when temperature reduces; Rotation speed of the fan descends, and ends up to not transferring to; Again work so repeatedly after the start.
The present invention can realize light modulation fast, unlike slower with the such light modulation of potentiometer, overcomes the perishable shortcoming of potentiometer, and is durable in use.Touch input mode and can be divided into several types such as resistance-type, electric wave formula, optical profile type, inductance type, condenser type and electromagnetic type.Wherein the capacitance touch input mode rely on its technology cost low, touch easy to detect and characteristics such as hardware is non-maintaining, become the main selection that touches input mode.Therefore the present invention adopts the capacitance touch input.
Because LED is a cold light source, To Be Protected from Heat,
Have considerableElectric energy is converted into heat energy, and cooling measure must be arranged, and develops by leaps and bounds though the LED luminescence technology is existing, and the report of every watt of luminous 200lm is arranged, and the LED heat radiation is very headache in the LED lamp, but the problem that is not also effectively solved.When using, the present invention adopts the PCB layout measure: the size that adds large bonding pad as far as possible; Under the situation that cabling allows with the line of broad; Outside the LED radiating end, overlay copper, strengthen area of dissipation, adopt aluminium base to be PCB.The present invention adopts the DS18B20 detected temperatures, and when the led array temperature was low, the control fan did not change, when temperature reaches setting value, and PWM adjustment dutycycle and then control rotation speed of the fan.
