基于CPLD与STM32结合的一种地物光谱仪设计

Design of a Ground Object Spectrometer Based on CPLD and STM32

地物光谱仪是农学、林学领域中广泛使用到的重要分析仪器之一。但是传统的光谱仪体积笨重,采集模块使用单一RAM设计,存在数据不能稳定采集和不方便携带等问题,给户外数据采集带来了一定的困难。所以研究一款数据采集稳定、数据传输便捷、操作方便的仪器就尤为重要。对此,本文提出了一种以STM32为主控制器,再搭载CPLD作为驱动数据采集模块,同时使用蓝牙无线数据传输的高效稳定传输光谱数据方法。通过实验测试,系统可以长时间稳定运行,解决了传统设计中存在数据采集困难、数据采集不稳定、仪器笨重不便于携带的问题。

Ground object spectrometer is one of the important analytical instruments widely used in the field of agriculture and forestry. However, the volume of the traditional spectrometer is bulky, and the acquisition module uses a single RAM design, so the data cannot be collected stably and is not convenient to carry, which brings some difficulties to outdoor data collection. Therefore, it is particularly important to study an instrument with stable data collection, convenient data transmission and convenient operation. In this paper, an efficient and stable spectral data transmission method is proposed, which takes STM32 as the main controller, carries CPLD as the driver data acquisition module, and uses Bluetooth wireless data transmission. Through the experiment test, the system can run stably for a long time, which solves the problems of data acquisition difficulty, data acquisition instability, cumbersome instrument and inconvenient to carry in the traditional design.
