Intelligent temperature measurement and control system:

the prior high-frequency induction brazing machine is controlled by time, namely heating current and heating time are determined through a large number of process tests, and equipment is set in advance according to data determined by the tests to control heating of workpieces. This is a way of empirical data, and the equipment is not known as to the most critical parameter of the workpiece, i.e., temperature. This design has adopted laser to aim at infrared radiation thermometer for measure and control the temperature of work piece.

(1) And temperature measurement:

the laser aiming infrared thermometer works on the principle that the surface temperature of an object is calculated according to the infrared radiation intensity of the object. The temperature measuring probe has the greatest characteristic that the temperature of a workpiece can be measured without contacting the workpiece to be measured, and the temperature measuring probe can be placed at the 350mm position of the workpiece to be measured, so that the temperature measuring probe is particularly suitable for measuring the workpiece which is difficult to approach or is not suitable to approach. This is the temperature measuring device that we need because our work piece temperature is high, can reach 900 degrees or so when heating to welding temperature, and the influence to the temperature probe is great at this temperature. In addition, induction welding is adopted in the device, a strong magnetic field exists around the heated workpiece, and if the probe is too close to the workpiece, the magnetic field interferes with the heated workpiece to generate large measurement errors. The non-contact measurement mode well solves the two difficulties. Meanwhile, the laser infrared temperature measuring device is specially calibrated for measuring red copper, the wavelength setting area of the device is very suitable for the heat effect of the red copper, and the device is basically not influenced by factors such as red, bright and black skin oxidation of the red copper in the temperature rising process.

(2) And temperature control:

the temperature is measured only by a value and the final purpose is control. The temperature measuring probe is combined with a temperature controller which is independently developed by people, so that the temperature of the workpiece is successfully controlled. The temperature control method has two options, namely a position type control mode, namely a PID control mode, wherein the position type control mode is a set target value, the workpiece is heated to the target value and stops, and the temperature oscillates within a certain range above and below the target value. The PID mode is a precise temperature control mode, maximum power is adopted for heating the workpiece at first, the heating power is continuously reduced while the measured temperature is continuously close to the set temperature, and the workpiece is slowly raised to the set temperature finally, so that the overall temperature of the workpiece is uniform, the welding is facilitated, the wetting of brazing filler metal is facilitated, and the brazing rate is benefited. A certain value can be set according to the requirements of a welding process, the laser temperature measurement sensor senses that a workpiece exceeds a set value, the workpiece is immediately changed into a heat preservation maintaining state, and heating is stopped after the workpiece is maintained for a set time, so that the detection of welding temperature is ensured, and the technical requirements of stable product quality and good consistency are met.

(3) Temperature setting, adjusting and displaying:

the temperature setting, regulation and display adopt a plurality of advanced technologies at home and abroad at present, such as a special microprocessor, an electrical erasing memory, a switching power supply, a special high-speed 16-bit A/D converter, an anti-interference automatic recovery technology, a non-overshoot PID algorithm and a PID self-tuning technology, so that the device is ensured to have the advantages of high measurement and control precision, strong anti-interference capability, complete functions, simple operation, wide adaptability and the like.
