Abstract
Bearing is common in mechanical products is extremely important a part in bearing assembly, we adopted is bearing heater inductive heating. This way is to control the temperature of heating bearing, the bearing type heat range. This bearing heater needs a temperature controller for the heating temperature controlling, man-machine interface in the whole process of temperature control is an important position. This design of man-machine interface in 16F877 PIC microcontroller systems as control core and with the temperature testing system, amplification system, A/D conversion, I/O devices unifies A temperature control system, the temperature control system is mainly used for bearing heater bearing heating temperature testing, through the keyboard by default heating temperature, temperature of heating tube digital display, and displayed by LED heating and heat (heating) function complete.
