摘要： 原子气室温度是直接影响无自旋交换弛豫(SERF)原子磁力仪的测量灵敏度的重要因素,本文设计研制了一种高精度的原子气室无磁加热系统。在硬件设计中,采用PTC加热装置与Pt1000温度检测电路共同构成完整的闭环控制系统。在软件设计中,针对不同目标温度范围,分别对P、I、D三个参数完成整定。同时采用积分分离式PID控制方法,以消除超调,并通过间断加热的方式满足磁力仪检测时的极低干扰磁场要求。利用该系统进行温度控制实验,温度控制范围为80~190 ℃,温度控制精度为±0.02 ℃,稳定时间为60 s,间断加热期间产生的干扰磁场低于0.1 nT,为SERF原子磁力仪的性能提升提供了可靠保障。

Abstract: The temperature of atomic cell is an important factor affecting the measurement sensitivity of Spin-Exchange-Relaxation-Free (SERF) atomic magnetometer. A non-magnetism heating system with high-precision is designed and developed. In hardware design, the PTC heating device and Pt1000 temperature sensing circuit are adopted to complete the closed-lop control system. In software design, the three parameters P, I and D are set respectively for different temperatures. Meanwhile, the integral separated PID control method is used to eliminate overshoot, and an on-off heating mode is used to satisfy the requirement for ultra-low magnetic field when the magnetometer is working. Temperature control test is performed using the developed heating system. The temperature control range is 80 ℃ to 190 ℃, the accuracy is ± 0.02 ℃, and the control procedure is 60 s. In addition, the magnetic interference is less than 0.1 nT when the heating is discontinuous, which provides the reliability to promote the performance of SERF atomic magnetometer.

Key words: electronic technology, spin-exchange-relaxation-free atomic magnetometer, non-magnetism heating system, digital PID control method, atomic gas cell
