This paper describes the use of a 1P801 SBC in the investigation on thermoluminescence and temperature dependence of luminescence to fulfil the requirement of automatic temperature control and automatic measurement of physical parameters. The system may acts as a constant temperature controller in order to study the relations between luminescence characteristic and temperature. It also may give heating rates of 4℃/min, 6℃/min,10℃/ min and 12℃/min in order to study the depth of trap level and their dis- tribution in samples. In addition, the computer may carry out the measurement of luminescence intensity and the calculation of the depth of trap level.Adopting computer Direct .Digital Control (DDC) and Sequence Control Counter (SCC), the system is flexible for changing or increasing its functions.This can be done simply by changing the system software.Fig.1 is the schematic diagram of physical experiment system. Fig.2 is the block diagram of computer control system.Adopting access form of temperature table, in the design of software, we are relieved from the tedious correction of experimental result.It is easy to change the temperature table when the thermocouple is changed.Z80-CTC is programed as a timer interrupting the Z80-CPU at time intervals desired and the Z80-CPU performs service programs once every interruption (controlling algorithm and measuring program etc.).It is the time base of linear heating. Having separated PD from PID by using algorithm logic in PID algorithm, we get an advantage that the overcorrections of variable to be controlled are decreased and the times to reach stabilization are shortened.In the design of hardware, interface circuits are suitable to different heating systems and multiparameter measurement. The measured thermolu-minescence curve may be printed by TP801-P microprinter and displayed on an oscilloscope. The real-time temperature and the deviation of the control system are displayed by LED (light emitting diode) of TP801. With these universal interface circuits, the system may be used in other experimental systems which need temperature controlling, multichannel measuring and general calculates.The sampling and middle value filter subroutines as well as the main program flow chart are recommended in this paper (see Fig.3,4,5). Incremental value equation of PID algorithm is also suggested.Fig.6, Fig.7 and Fig.8 are the examples of experimental curves. Fig.6 is the thermoluminescence curve of ZnS: Cu,Co which is measured with the temperature of the system automatically controlled (above room temperature) and printed by TP801-P microprinter. Fig.7 is the thermoluminescence curve of the same sample which is measured with the manual temperature control and plotted on a X-Y recorder. Comparing these two curves, we can see that the resolution of trap energy spectrum is improved when heating rate is controlled by the computer. Fig. 8 is the emission spectra cf Y2O2S:Eu (1×10-4) at different constant, temperatures which are controlled by the computer. The curves were plotted on a X-Y recorder.
