Abstract

The invention discloses an AT89C51 single chip microcomputer infrared temperature measurement system. According to an existing tempering process, a heating temperature is required to be 205+ / -5 DEG C, heating voltage is controlled, no temperature measurement device or recording is available, and the existing tempering process does not conform to the requirements of an ISO9000 quality system. The AT89C51 single chip microcomputer infrared temperature measurement system comprises a power management module, a control module, a signal collection module, a programmable interface module, a scanning operation module and a temperature display module. Analog signals are formed by conversion according to collection of outside temperature through the signal collection module, are transmitted to a controller and then are converted into digital signals through the controller, the digital signals are displayed on a nixie tube, operators can clearly know temperature of a heated device, and the temperature is adjusted so that the process can meet the requirements.

Description

technical field [0001] The invention belongs to the field of single-chip microcomputer systems, and relates to a temperature measurement system, in particular to an infrared temperature measurement system of an AT89C51 single-chip microcomputer. Background technique [0002] With the development of modern industrial production, the use of power frequency induction heating furnaces is becoming more and more extensive. The power frequency induction tempering furnace adopts the principle of induction heating for heating. Put the bearing ring in the induction coil with sufficient power output, under the action of the power frequency alternating magnetic field, a strong induction current is formed on the surface of the workpiece, so that the workpiece can heat up rapidly, thereby realizing the tempering of the workpiece. The characteristic of the construction design of the induction heating tempering furnace is that except for the heating temperature of the workpiece, all other ...
