摘要
针对目前光学微球腔的温度控制方法计算繁琐、选用器件复杂，且精确控温时对应温度范围较小的问题，提出了光学微球腔温控封装平台设计方法。该方法采用增量式PID控制策略，通过测温模块三线制Pt100铂电阻和恒流源法进行测温，由制冷片和加热片组成的温度控制模块进行制冷和加热，最后由温度调谐平台进行精确温度控制。仿真测试证明，该方法制冷时温控平台大约需要13～14min达到稳定，温度波动范围为±0．02℃．力口热大约需要15~16min达到稳定，温度波动范围为±0．04℃，温度范围由原来的9～20℃上限提高到35℃，控制精度优于0．1℃。
In view of the complexity of calculating the temperature control method of the optical microsphere cavity, and the problem that the temperature range is smaller, a temperature control package designing method was proposed. This method used an incremental PID control strategy. Through three wire Ptl00 platinum re- sistance temperature measurement module and temperature measuring method of constant current source to measure temperature, using the refrigeration and heating pills temperature control module cool and heat it. Final- ly applying tuning platform for precise temperature control. The simulation tests proved that the method when the cooling thermostat platform takes about 13 -- 14 minutes to stabilize the temperature fluctuation range of ＋0. 02 ℃, heating takes about 15--16 minutes to stabilize the temperature fluctuation range of ＋ 0. 04 ℃, the temperature range from 9--20 ℃ to maximum 35 ℃. The control accuracy is preciser than 0. 1 ℃. The imple- mentation of microsphere cavity temperature control precision, provides a new method for control of microsphere cavity temperature.
