基于模糊PID的花椒烘房温度自动控制系统

针对中国目前农村花椒烘房烘烤花椒的温度控制方式仍采用人工控制的方式，存在干燥不均匀，干燥速率相对较慢，能耗损失较大等问题，该文首次系统地将模糊PID温度自动控制技术应用在花椒烘房的自动干燥上，研究对比了PID控制技术、模糊控制技术和模糊PID控制技术在温度自动控制系统中的功能特点，并结合32位ARM处理器和GPRS技术实现花椒烘房的自动控制和远程报警提示，这有利于解决目前农村地区自动控制设备通讯难的问题，能为中国农村花椒干燥自动化应用提供一种有效的解决方案。

Automatic temperature control system of zanthoxylum drying room based on fuzzy-PID

At present, the temperature of the zanthoxylum drying room is controlled manually in China. It has some disadvantages such as non-uniform drying, slow drying rate and high energy consumption. Therefore, in order to improve the drying quality, an advanced automatic temperature control system based on fuzzy-PID was proposed to apply in drying zanthoxylum. The functional characteristics of PID technology, fuzzy control technology, and fuzzy PID control technology were compared in the paper, and the 32-bit ARM processor was combined with the GPRS technology to realize the automatic control and the remote alarm in the zanthoxylum drying room. The inconvenient communication problem of automatic control equipment was solved. The automatic temperature control system based on fuzzy-PID could provide an effective solution scheme for automatic zanthoxylum drying in the rural area of China.
